There are precautions for safety in the seaWhich

To determine the date of going to the sea, you must understand the weather and sleep on the day before going out to sea.

Before sailing: Observe the maritime conditions (understanding the marine, sea conditions, self -physical, supporting situations), the planning of the voyage (time, route, reporting, watching), checking the boat, the guidance of the coach, the preparation of the lifeboat, the preparation of the lifeboat, the preparation of the lifeboat.Wait.

During sailing: observe all kinds of changes (weather, physical strength, walrus) at any time, and immediately return to flights, do not make unsure or beyond physical and technical scope.

After returning navigation: After returning, return to the base, review the lack of this voyage, check the maintenance boats, etc.

Clothing and equipment: Comfortable clothes, non -slip and white -footed white background shoes with both feet, and do not step on beautiful decks, just like getting off the shoes after getting started in other people's homes to show respect and keep them clean.Sailor hats, sunscreen oil and sunshade glasses with protective bands.With more warm clothes to use the sea breeze, the waterproof jacket can maintain the dryness of the body.Bringing gloves at work can also protect your hands while pulling.waterproof lift Bags and all -weather clothes are the best equipment for bad Tianhou.

Be careful when boarding the Ship: Pay attention to boarding etiquette. First of all, you need to obtain the captain's consent to board the Ship. Just as you are invited to enter the house of others, you must be very careful when boarding the Ship, especially when you use a ladder or a small boat when you are at a low tide.When connecting to the big Ship, when crossing the side cable, the feet are bent back to maintain the center of gravity of the body. After boarding the Ship, place your own personal equipment on the proper position of the cabin and prevent it from being moved when the hull is tilted.

The boat club often keeps tilting or suddenly unexpectedly tilted, especially for beginners who are not accustomed to acting in the tilt hull. In real timeThe fixed device on the planting boat can help you stand up. When walking, your body is slightly bent and walks, keeping the center of gravity reduction, and be careful not to hit the truffle mast or let it hit you.Walk on the deck to keep on the upper side for safety.

Safety equipment: Not only protecting Ship equipment but also protecting individuals, they must know their location and proper use method, and it must be used to use it; it is necessary to prepare items when sailing near the shore (list some of the following equipment).

Safe vest: Each person must have a qualified and suitable vest, and children must prepare special size vests for them.

Lifeline: It is easy to use on the boat, and some people can quickly throw them towards the falling water when they fall into the water.

In addition, emergency medication packs, pumps, buckets, fire extinguishers, anchors and anchor ropes, sea charts, fog numbers, waterproof flashlights, flame signal bombs, auxiliary engines, sailing Lights, communication equipment, Telescope, and so on.

For the safety and joy of your maritime journey, please read the following content carefully and strictly obey before going out of the sea.

1.No smoking on the dock and boat;

2.Any disease, hypertension, diabetes, asthma, asthma, infectious diseases, muscle paralysis, osteoporosis, and other diseases that affect the safety of the boat and pregnant women and severe seasickness, please do not take the boat.The boat was unexpected, and the consequences were at your own risk;

3.Tourists must line up to board the boat under the guidance of the staff. Pay attention to safety on the sea viewing platform and floating pier, so as not to lose their feet and fall into the sea.

4.Elderly people over 60 years old and children under the age of ten should be accompanied by a boat, and the approved by the captain must be obtained before going to the sea;

5.After boarding the Ship, please listen to the explanation of the captain or other staff on board, including the use of itineraries, sea conditions, safety facilities, etc., and consciously wear life jackets;

6.Please keep your own mobile phones, cameras, cameras and other valuable items to avoid being lost or falling into the water;

7.During the navigation process, tourists should be firmly grasped and worn in life clothes. At the same time, they should obey the commander of the captain or staff. If there is discomfort, report to the captain in time;

8.During the speedboat, it is strictly forbidden to take an umbrella, take pictures, photography and other behaviors that affect speedboats and personal safety;

9.Do not touch the navigation instruments and instruments on the driving table and other boats.

10.In order to protect the marine environment and maintain the hygiene of the boat, it is strictly forbidden to discard garbage in seawater and cabin;

11.It is strictly forbidden to bring a pet, cat and other pets to bring up the upstream yacht;

12.In the process of diving, fishing or swimming activities, tourists should strictly abide by the captain or staff in accordance with the conditions and requirements of the situation and the environment at the time, and generally can only move around 8 meters around the yacht.

What are the precursors of Earthquake

In recent years, the frequent Earthquake has brought a lot of threats to people's lives, which has also caused a lot of difficulty to make up for it.The occurrence of natural disasters will always be accompanied by some signs. As long as you look closely, you may avoid some disasters.Mastering the precursor of earthquakes may be able to fight for more escape opportunities.(Special explanation: The statement of the precursor of Earthquake exists only in the people, and it is not supported by scientific theory. The following content cannot be regarded as a scientific fact, but it is worthy of our attention.)

Prior to the Earthquake, various signs of the occurrence of earthquakes and the occurrence of the occurrence of earthquakes are called seismic precursors.There are two categories:

1. Micro -precursor: Human senses are not easy to detect, and the pre -Earthquake changes that can be measured by instruments must be used.For example, the deformation of the ground, the changes in the magnetic field of the earth, the changes in gravity fields, the changes in the chemical composition of groundwater, and the activity of small earthquakes.

2, macroendross: human sensory can notice the precursor of earthquakes.Most of them appear near the Earthquake.Such as the rising and downs of well water, abnormal animal behavior, sound, ground light, etc.

Why is there abnormal changes in groundwater before the Earthquake?

When the underground rock layer is deformed before the Earthquake, the groundwater buried in the water -containing rock layer will also change.Sometimes, the water -containing layer is squeezed out of the water like a sponge full of water; sometimes, the water partial layer is ruptured to mix the original layered flowing water; and so on.These changes may be reflected through well water, spring water, etc. At this time, wells or springs have become the "window" for people to observe the precursor of the Earthquake.

What are the abnormal changes in groundwater before the Earthquake?

The abnormal changes in water Levels and water volume.For example, the water level of the well in the season rises, and the amount of water in spring increases the water;Sometimes the phenomenon of self -flow and self -spraying of well water.

change of water quality.Such as well -changing, taste -changing (such as becoming bitter, sweet), turning, odor, etc.

change of water temperature.Water temperature exceeds the range of normal changes.

others.Such as bubbling, jets, and deformation of the well wall.

Is the groundwater abnormalities related to the Earthquake?

uncertain.Because groundwater is easily affected by the environment, its abnormal changes are not necessarily related to the Earthquake.The factors that affect the changes in groundwater are: meteorological factors, such as drought, rainfall, air pressure changes, etc.; Geological factors, such as non -Earthquake geological reasons, change the state of underground water layer; human factors, such as changes in water volume, underground engineering activities, environmental environmentPollution, etc.Therefore, after discovering abnormalities, it is necessary to reflect the causes to find out the cause and make judgments in a timely manner.

What are the performances of animal behavior abnormalities?

Many Earthquake examples show that animals are "living instruments" to observe the precursor of earthquakes. They often experience various abnormal behaviors before the Earthquake, which foreshadow people's approaching the disaster.At present, there have been hundreds of abnormal performance before the Earthquake is found. Among them, there are more than 20 kinds of abnormal reactions. The most common animal abnormal phenomena are:

A panic reaction, such as the big livestock, the Dogs bark, the birds or insects are shocked, and the non -normal movement is relocated.

Inhibitory abnormalities, such as behavior becomes slow, or dazed, at a loss; or not willing to eat.

The changes in living habits, such as hibernating snakes, mice are not afraid of people during the day, and a large number of frogs go ashore activities.

Is the abnormal animal behavior related to the Earthquake?

uncertain.There are many factors that cause animal abnormalities, such as weather changes, environmental pollution, improper breeding, and animal discomfort, such as illness, pregnancy, and so on.Therefore, the abnormal manifestations of animals are not necessarily a precursor to Earthquake.In addition, sometimes (especially after the strong Earthquake occurs), people are too nervous, and may also have an illusion when observing animal behavior.Therefore, do not panic after discovering abnormalities, and should be reflected to the seismic department in time.

What do you think of abnormal weather?

Radio Cloud: The floating clouds will have a very long ray in the sky. The position of the shot center is the position of the central Earthquake. Such a ray cloud is easily observed by people.

Earthquake cloud: Earthquake clouds are a cloud of cloud classification in non -meteorological science. The color of the cloud body before the Earthquake is: white, gray, orange or orange -red.The characteristics of Earthquake clouds: The wind is not easy to change its form. The sky and the cloud have obvious boundary lines, and there are more waves.

There are two ways of formation of Earthquake clouds:

Calorie theory: When the Earthquake is about to occur, a large amount of heat is caused by the geothermal gathered in the Earthquake Belt or due to the strong gravity effect of the Earthquake Belt.A "Earthquake cloud" is formed at a high altitude, and the end of the cloud is pointed at the location of the Earthquake.

Electromagnetic theory: Before the Earthquake, the rocky of the rocks occurred under geomantic stress, which caused local changes in the geomagnetic field; the geographical stress caused the rock to be compressed or stretched, causing the resistivity of the resistivity, and the corresponding local changes in the electromagnetic field.Because the electromagnetic wave affects the high -altitude ionization layer, the concentration of the ionizing layer of the plasma decreases sharply, which makes the orderly arrangement of water vapor and dust and the non -freedom of dust forming a Earthquake cloud.

Earthquake cloud detailed analysis:

If the length of the Earthquake cloud is very long, the closer to the time of the Earthquake; if the color of the Earthquake cloud looks deep, the depth of the corresponding Earthquake is deep; if the Earthquake cloud lasted for a long time, then the place will beThe closer to the corresponding epicenter; if the color of the Earthquake is gray, it means that the Earthquake is very serious.

What are the characteristics of the ground and what are the characteristics of it?

Before the Earthquake occurred, there was often a sound from the depths of the ground. This is the "sound of the ground."The sound of the ground generally appears in the before, hours, days, or earlier; the most minutes before the Earthquake appear.

The sound of the ground sound is different from the familiar sounds that people are usually familiar with.Such as: "It's like a train coming from underground Mercedes", "sound like a stone -picked beaded cannon", "similar to the roar of the machine", "the sound of the wind", "the sound of the stone rubbing each other" and so on.However, sometimes it is not easy to distinguish between wind, thunder, and roar from the distance from the distance.

What are the characteristics of the light?

Di Guang is also a macro phenomenon before the Earthquake. my country has been observed before many earthquakes. They generally appear in front of the Earthquake or when the Earthquake, and there are also some hours or earlier before the Earthquake.

There are many colors of ground light, including red, yellow, blue, white, purple, etc. Some are also like electric fire light.They have different shapes, including light, sheets, spherical light, cylindrical light, fire -like light, etc.The time when the ground light appears is generally short, so it is not easy to observe.It is also difficult to identify the light, because its shape and color are sometimes similar to the welding light and lightning.

In summary, observation of micro -precursor is the work of scientists.It is found that the macro -precursor near the Earthquake depends on both scientists and the masses.Because macro -precursors often occur when the Earthquake occurs near the Earthquake. Therefore, understanding its characteristics and learning to identify them will play an important role in Earthquake prevention and disaster reduction.

What are the characteristics of abnormalities?

Earthly gas refers to the fog before the Earthquake, also known as the fog or ground fog.This mist has a variety of colors such as white, black, yellow, and sometimes colorless. It often appears within a few days before the Earthquake, often accompanied by strange taste, sometimes accompanied by sound or high temperature.

What are the characteristics of ground movement abnormal?

Di movement abnormal refers to the shaking of the ground before the Earthquake.The severe vibration of the ground during the Earthquake is a well -known phenomenon.However, before the Earthquake occurred, sometimes I felt the ground shaking. This shaking is different from the Earthquake. The swing is very slow. The seismometer is often recorded, but many people can feel it.The most significant ground movement appeared before the 7.3 magnitude Earthquake of Haicheng on February 4, 1975. From late December 1974 to the end of January 1975, in Dandong, Kuandian, Fengcheng, Shenyang, Xi [xi],There have been 17 places in the place.

What are the characteristics of ground drums?

Drum abnormalities refer to drums on the ground before the Earthquake.About half a year before February 6, 1973, Sichuan Huohuo 7.9 earthquakes, a drum appeared on a lawn in Daoba District, Ganzi County, with a shaped iron pot, which was about 20 cm high.After a few days, disappearing, repeated multiple times until the Earthquake occurred.Similar abnormalities as ground drums include ground cracks and land.

What are the characteristics of electromagnetic abnormalities?

Electromagnetic abnormalities refer to abnormalities in household electrical appliances such as radios, televisions, Solar lamps, etc. before earthquakes.The most common electromagnetic abnormalities are the failure of the radio, and it is more common before the sunlight in the northern region before the Earthquake.A few days before the 7.8 magnitude Earthquake in Tangshan on July 28, 1976, many radios in Tangshan and its neighbors failed. The sound was big and small, sometimes there was no frequency, and sometimes noise appeared continuously.Before the Tangshan Earthquake, some people in the city saw the off -off fluorescent Lights turned red at night. Some people in Beijing turned off the sunlight before going to bed, but the Lights were still lit.

Electromagnetic abnormalities also include the abnormal work of some motor equipment, such as microwave abnormalities, disturbing radio plants, and electronic alarm failure.

Why do the ground bump and shake before the Earthquake?

When the Earthquake bumps first and shakes, the speed and method of the spread of Earthquake waves are different.The spread of Earthquake waves is usually divided into two categories, one category spreads inside the earth into a body wave; the other is spread along the ground surface and the surface of the rock layer, which is called face waves.Body waves are divided into longitudinal waves and horizontal waves.The longitudinal waves were passed on to the surface first, and the range was between 1 km and 20 kilometers, with a speed of 7 to 8 km/s; and the speed of the horizontal wave was only 4 to 5 km/s, and the slowest of the face wave was only 3 kilometers per second.Due to the physical characteristics of waveforms caused by the physical characteristics of waveforms, the upper and lower bumps of the ground objects, that is, people feel that they are moving up and down first.The horizontal waves are slow, and then the waveform characteristics are to shake the object left and right.Therefore, people feel that they move up and down after moving up and down, and the coherent Earthquake comes to bump and shake.

Earthquake escape self -rescue knowledge

What should we do when the Earthquake comes?There is a "12 -second self -rescue opportunity" in the Earthquake psychology, that is, after the Earthquake, if you can quickly avoid it to the safe place within 12 seconds, you can provide yourself with the last chance of self -rescue.

1. Hiding under the table and other solid furniture.The large shaking time during the Earthquake is about 1 minute.Avoid the low center of gravity and strong and firm table, and grasp the table legs tightly.In the case where there are no tables such as a table, you must also use cushions and other things to protect your head.

2. Turn off the fire immediately when shaking, and immediately extinguish the fire when the fire is lost.During the Earthquake, turning off fire and fire extinguishing is an important factor in controlling the minimum degree of Earthquake disasters.1Within -2 minutes, it can still be extinguished.

3. Don't run outdoors.After the Earthquake, it was very dangerous to run out of panic, crushing glass, bricks and tiles on the roof, billboards, etc., which was very dangerous.In addition, the cement prefabricated board wall and automatic vending machine also have the danger of collapse, do not approach these objects.

4. Open the door to ensure export.Houses with steel cement structures, etc. Due to the shaking of the Earthquake, doors and windows are misplaced, and the door cannot be opened. Therefore, the door should be opened to ensure export.

5. Outdoor occasions should protect the head and avoid danger.When earthquakes, people have the psychology of helping and catching.Most of the pillars and walls around them will become the object of help.However, these things that look strong and firm are actually dangerous.In the prosperous street and building area, the most dangerous is glass windows, billboards, etc. falling down and smashing people. Pay attention to protecting the head by hand or handbags.In the building area, it is safer to enter the building according to the situation.

6. In the instructions of the staff during the department store and theater.There are many places such as department stores, underground streets, and other people, in accordance with the instructions of store staff and guards, take action calmly.

In case you encounter an Earthquake when you ride an elevator, press all the buttons on each floor on the operation board. Once stopped, quickly leave the elevator and confirm the safe shelter.

7. car parking on the side of the car, the control area is prohibited from driving.When the Earthquake occurs, the car will not be able to grasp the steering wheel and it is difficult to drive.You must avoid the crossroads and stop the car on the side of the road.In order not to prevent people who evacuate from evacuation and emergency vehicles, the middle part of the road must be given.

8. Be sure to pay attention to landslides, cliffs fall or tsunami.In the mountains and steep tilt areas, there is a danger of landslide and cliffs.On the coast, there is a danger of tsunami, and quickly goes into refuge in a safe place.

9. Hiking should be treated during refuge, and items should be carried at least.After the Earthquake, it is advisable to take a trekking asylum, and the items you carry should be at least.You must not use cars and bicycles to take refuge.

10. Don't listen to rumors, don't act lightly.When a Earthquake occurs, people are psychologically shaken.In order to prevent confusion, everyone takes action calmly according to the correct information.Grasp the correct information from the radio and other carriers.I believe that the information directly from the government, police, fire protection institutions and other disaster prevention agencies will never trust irresponsible rumors, and don't act lightly.

Different places to avoid points during earthquakes

1. school.In school, we usually need to combine teaching activities to tell students about Earthquake and prevention, Earthquake avoidance knowledge, and arrange the routes and venues of students' transfer and evacuation. In relatively strong and secure houses, they can avoid it under the desk, the podium, and the podium.Beside, students in the teaching building can go to the room with small and pipelines, and never let students run or jump off the building, do not go to the balcony.After the Earthquake, evacuated in an orderly manner.

2. Pedestrians.When the Earthquake occurs, the glass fragments of high -rise buildings and concrete pieces outside the building, as well as advertising signs, pamura iron plates, neon light racks, etc., may be hurt. Therefore, when walking on the streetThe items are on the head, and when there is no item, you can also use your hand on your head to prepare for self -defense as much as possible. To be calm, you should quickly leave the electric pole and wall and run to a broader area to avoid.

3. Drive.(1) The driver should slow down as soon as possible to gradually brake; (2) Passengers (especially on the train) apply to hold their hands, pillars or seats, etc., and pay attention to prevent the luggage from falling from the rack from the rack, facing the driving facing the driving faces, facing the driving facing the driving facing the driving facing the driving faces, facing the driving facing the driving facing the driving facing the driving facing the driving faces facing the driving facing the driving facing the driving faces facing the driving facing the driving facing the driving faces facing the driving facing the driving facing the driving facing the driving facing the driving facing the driving facing the driving facing the driving.The person in the direction should lean his arms on the chair cushion in front of the front seat, protect the face, the body tends to the passage, and protect the head with both hands; the person who is facing the direction of the driving direction, should protect the back of the brain with both hands, and lift your knees to protect the abdomen.Tighten your body and make a defensive posture.

4. Inside the building.First of all, keep a sober and calm mind and judge the vibration status in time. Do not jump off the building in a panic. This is extremely important.Secondly, you can avoid it under solid furniture (remember not to hide under the bed, but you can hide from the bed, the area of the bed is large, and the person who has too much weight can easily overwhelm the person under the bed, and the bedside can play a supporting role), or the corner corner of the cornerAt the point, you can also transfer to the load -bearing wall, the kitchen and the toilet for a temporary avoided.These places have strong combination, especially the pipelines have been treated with good support, and the seismic coefficients are large.

5. In the store.Due to the panic and the whereabouts of the goods, the shelter channel may block.At this time, you should hide next to the large pillars and big products (avoid the product display cabinet), or avoid the passage of no obstacles, and then squat and wait for the Earthquake to calm down.In the upstairs position, it is better to transfer to the bottom layer in principle.However, stairs are often weak parts of building earthquakes. Therefore, it is necessary to see the right time to escape risk, but avoid it nearby and evacuate after the Earthquake.

Common sense of hedging self -rescue after Earthquake

1. If you are buried under the ruins during the Earthquake, you must establish the confidence of survival. I believe someone will save you.

2. After the Earthquake, there are often many aftershocks, avoiding the sturdy collapse above the body and other objects that are easily caused by falling.After the occurrence, the environment worsen further.

3. Protect the Smooth breath and move the debris on the head and chest. When smelling gas and poisonous gas, cover the mouth and nose with wet clothes (but the protective fabric of dust pollution to cover the mouth and nose).

4. Try to leave the danger.If you can't find a passage from the danger, try to keep your physical strength, use stones to knock on objects that can make sounds, send a call for help, don't cry, irritability, and blindly act.Control your emotions or rest, wait for rescuers to come.If you are injured, you must bandage to avoid excessive bleeding.

5. Maintain life.If the time buried under the ruins is relatively long, the rescue personnel have not arrived, or if they do not hear the call for help, you must find a way to maintain your life.Putting water from water to prepare for the need, when necessary, your urine can also play thirst for quenching thirst.

skills and precautions for water rescue

The principle of rescue on the shore is not easy to get off the water for rescue

"Breathing" is the basis of all water rescue activities. Breathing is called "life -saving qi". Only by mastering the water breathing method can we rescue the drowning person with time, and the breathing will also run through the entire water rescue process.

In the case of drowning, the rescuer should handle it from the following four aspects:

1. When seeing someone drowning, the first reaction must be shouted loudly to attract the attention of the surrounding people. If the rescuer is unfamiliar with water, he can call the people who are familiar with water.As the saying goes, many people are powerful, attracting the attention of other people to make subsequent rescue operations more timely and efficient.

2. Play 119 or 110 alarm and contact 120 emergency units in time.

3. Rescuers can use life -saving equipment to rescue the sober drowning people.These life -saving equipment include lifebladder, bamboo poles, wooden boards, foam blocks, ropes, etc.Rescuers should respond in time and create rescue conditions in the limited environment.When the drowning person is closer to the land, you can use a bamboo pole to rescue the drowning person. If it is far from the land, you can tie the rope to the drowning person after the rope is tied to the drowning.

4. After the above three methods are carried out, if the drowning person cannot be separated from the water, the rescuer can fix one end of the rope on the wooden stake or stone on the land, and the other end is firmly tied to the ground.Put your waist and launch.However, Wang Tao believes that if you have to do not have, it is best not to launch the water if the rescue should not be launched.

[Inflatable life jacket] The scope of application principle of inflatable life jacket work inflatable life jacket

Origin -Who invented the "life -saving vest"

In 1944, the former President Bush, as a naval pilot, was shot down over the Pacific Ocean, but he succeeded in parachute and escaped. He was wearing an inflatable "life -saving vest".And the invention of life vestAndrew Totti has always been considered a hero.

However, today, who has invented the "life vest" for decades later, it has caused controversy.After investigation, there was no record of Totti invented in the patent record.A person named Peter Marcus registered the patent of life jacket in 1928, and his design was very similar to the World War II military life jacket.

Is there a patent record of Macus in the archives?

The life -saving vest is an inflatable vest life jacket worn by pilots when flying over the sea.As the inventor, Totti has been praised by people. Of course, the most grateful to him is the old Bush.

Until March this year, after the 89 -year -old Totti died, people still praised his invention as always in the prosecution, grateful for everything he did to save the life of the future president.

But then, the government's documents showed that Peter Marcus had obtained the patent right in 1928.That is, a few years ago when Tott began to design a life jacket, Marcus had begun to study and improve life jackets with the military.Marcus died in 1973.Macus's son and Alvin from Los Angeles provided several certification documents to the Associated Press.The document shows that on December 11, 1928, Marcus's "inflatable life utensils" obtained a patent with patent number 1694714.At that time, Totti was only about 11 years old.

Subsequently, the Associated Press reporter found in the military -related records of the National Archives that since 1930, the Naval military has begun to create a life jacket designed by Marcus.

Toti frankly accepted the praise and wrote the "Congress Records"

Tetty's will and mechanic Russell Hindley revealed that Totti said that when he was a teenager, he sold his life -designed life jacket to the US Army at the time.

"(He) has never said that he is the inventor. He has always called himself a partnership," Xinkeli told the Associated Press reporter that he worked with Totti for decades. ") Have contributed. But Peter Marcus is the inventor. "

Totti has hundreds of invention patent rights, including automatic chicken wiper and respiratory straws for surgery.Over the years, when others praised him invented a life -saving vest, Totti obviously had not denied it.

In 1995, the "ranked" magazine in the United States also wrote Totti.Last year, Republican Dennis Cato from California also praised him to save the life of the future president.Kadaza even wrote Totti's deeds into the Congress record.

The life jacket has continued to improve the reporter's investigation and the inventor failed

Prior to the release of Toti, Alvin said that he had never heard of Totti, let alone Totti selling the life jacket to the military."Selling $ 1500 is a joke at all," he said.According to him, his father, Macus, has obtained thousands of dollars of patent use fees from two authorized rubber companies.However, he also acknowledged that Totti may have improved some improvement in life jacket design.

In order to clarify the matter, the New York Times hired a professional patent lawyer Steven Liberman to inquire about the patent records, but no record of Totti inventing a life jacket was found.The life jacket designed by Marcus is the most similar to the life vest used by the military in the patent record.

In fact, before World War II, people have been constantly improving life jackets.A long time ago in Marcus's registration patent, some people have obtained similar patent rights.Therefore, the life jacket used by the military during World War II may also be from the hands of others.

The working principle of inflatable life jacket

The inflatable life jacket has two functions: manual exhaustion and automatic inflatable.

1. Manual inflatable: Pull the pull rope on the inflatable device before or after falling or after falling or after falling or after the water, so that the tie rod is not less than 90 degrees, the thorns are pierced to pierce the gas cylinder film, the high -pressure CO2 gas is poured into the airbag, and the buoyant is generated after the gas swells.

2. Automatic inflation: After the water is dropped into the water, the life jacket is immersed in the water to soften the water sensitive element in the automatic device, loses blocking the needle, and the spring stretch pushes the piercing needle to pierce the gas cylinder sealing film CO2 gas to fill the airbag and generate buoyancy.

3. Blowing the mouth is a one -way valve type, and the one -way valve is automatically closed after blowing.
