1. What is swimming life -saving equipment

swimming life -saving equipment, scientific name, swimming float, also known as floating ball, is a life -saving float, a striking orange airbag, a long strap, one tied to the swimmer's waist, and one orange airbag.Looking from a distance, like a chubby little bug followed the swimmer.

This kind of life -saving float is a life -saving equipment designated by the International swimming Federation and the China swimming Association. The design of the double airbags will not affect the swimmer swimming, and it is safer than the lifeburn.In terms of use, it is also more convenient. The length of the band is well controlled and is not easily entangled.And the swimming float color is eye -catching, and it can be used as a life -saving symbol in water.Carrying swimming life equipment in open waters can prevent many swimming accidents from happening.

2. What are the advantages of swimming floating?

1. It can play a warning.The color is bright and can prevent accidents with the traversal.

2. When swimming needs to supplement food or water, you can grasp the swimming float and press it into the water with the help of buoyancy to rest. After the discomfort is eliminated, the physical strength recovers, you can continue to swim.

3. It can play a role in self -rescue.In the event of an accident when swimming, or cramps in the legs, you can save yourself and rest, waiting for others to help further.

4. Can play a role in rescue.Once you really meet a swimmer, you need to help, unlock your swimming float in time, and use it for swimming friends to save each other.

5. You can support it when you are inadequate.Tour swimming floating in the river, lake, and reservoir, tired, you can climb in swimming floating and rest, and then take a rest and rest, so that the swimmers can quickly improve the travel journey.

Third, the shortcomings of swimming floats

1. It may leak air.

2. It is not easy to catch it too much. When the flood is large, it is easy to entangle floating bamboo, branches, anchor cables (ropes), etc., and it is not easy to liberate.

3. When saving people, they cannot dive in time. After swimming in deep water, after the drowning person sinks, the general rescuers generally give up because they cannot dive to the end.

4. What are the types of swimming floating?

1. Rugby -style swimming float

This is the most common float. This kind of swimming float is suitable for swimming pools, rivers, and lakes.Generally speaking, it is suitable for waters with small storms.

2. Flying sauce swimming float

swimming floating inner storage warehouses are suitable for swimming enthusiasts in the shore with small waters with small storms and Outdoor swimming.

3. Pillow -shaped swimming float

This swimming float is large, because there are ropes on the side, which are easy to grab in the water, and are often used in open waters of large storms.

4. Cillar swimming float

Because of its large buoyancy, it can be used in clothing and other characteristics. It is often used for long -distance drift swimming and winter swimming.

Swimmer said

The warning and psychological suggestion of swimming floats are greater than the actual effect.I bought one, tens of yuan, can put some small things, which is very convenient.The trumpet can provide enough buoyancy of adults, but this person who can swim and has a floating foundation.

Do not swim, do not float, or have no sense of balance, and the effect will be poor.

Check the closed conditions before. After launching, be careful not to damage the sharp objects. Pay attention not to entangle your body and cause panic.

swimming is not absolutely safe. It is best to keep the three -point strength in the wild.

What is the material of the life jacket

Life -saving fabric

1. Special nylon material

This kind of fabric is relatively low in price, wide use, but not durable

2. Neoprene choprene rubber (diving material)

This kind of fabric is more expensive, feel soft and comfortable, friction, as long as high -end life jackets can use this fabric.

Life -saving clothing

1. Polyethylene foam plastic

The price of this linoleum is relatively low, with sufficient buoyancy and wide use surface, but the buoyant of the buoyance will change with the time of soaking in the water at about 5%.

2. EPE pearl cotton

The price of this linoleum is obviously more expensive than the foam plastic, and its advantages are obvious.The buoyancy is strong, the life jacket is easy to fold, and it is easy to dry. More importantly, the buoyancy is soaked in the water for a long time.

Life clothing material requirements

1. Plastic should be a soft -closed foam plastic. During the validity period, it is not affected by the erosion of seawater, oil or mold and affects its normal use.It can be stored within the temperature range of -30C to 65C (243 ~ 338K) without damage. It can maintain its performance within the water temperature range of -1c to 30C (272 ~ 303K).

2. Rich kapok oil and must not contain other impurities. The physical properties and moisture content should meet the requirements of norms.After being surrounded by hydrocarbon flames for 2 seconds, the source of the fire should not be burned.Between the kapok and the raw clothing cloth of the kapok life jacket, there must be a waterproof inner cover made of rubber or other waterproof materials.

What is the role of life jacket

1. Help people float on the water

Putting on a life jacket allows people who can't swim to keep their heads exposed to water, thereby reducing the probability of drowning.For those who can swim, the buoyancy of life jackets can save them more physical strength.

2. Cold protection and warmth

Most of the life jackets are made of foam plastic. In the cold water, it can effectively keep warm and reduce the loss of human heat.

3. increase the rescue rate

life jackets are generally bright in color and have anti -light strips, which are convenient to be discovered.At the same time, many life jackets and survival whistle can help people send a distress signal without physical saving.

4. increase the survival rate

Safe clothes can help people float on the surface, which greatly reduces the probability of drowning.At the same time, many life jackets are also equipped with first -aid Bags, which can help people survive better in the harsh living environment.

1. Put your head into the life jacket.

2. Tie the straps on the left and right sides.

3. Pull the tension on the left and right sides, the inflatable valve is opened, and the life jacket is inflated within a few seconds.

The inflation function of the qi -blee -type life jacket

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.

What are the types of qi -style life jackets?

Blay -type life jackets are divided into three types according to the appearance style:

1. Vest -style qi qi and life jackets are commonly known as horses -type qi qi life jackets.

2. scarf -style qi and life jackets are tied to the neck like a scarf.

3. Belt Bloating life jacket, also known as qi -type Belt life ring, water seat Belt.

There are two specifications of all styles of qi and life jackets, one manual type and one automatic type.Suitable for fire, maritime police, water police, armed police, border defense, maritime affairs, fishery administration and other units to engage in water rescue activities.

The performance indicators of qi -blee -type life jackets

1. Automatically inflatable within 5 seconds of water, generate more than 15 kg of buoyancy.The 24 -hour buoyancy loss is less than 5%, and the performance of the main accessories and materials meets national standards.

2. The airbags are made of imported polyether TPU materials, which have excellent aging resistance and hydrolysis characteristics.

3. The dry side of the water is greater than 120mm, and the backward angle is 20-50 degrees.

4. The product is standard for search whistle and reflective stickers.

What are the fabrics of qi -qi -type life -saving clothing

Bid-type life jackets use TPU fabrics, TPUs (Thermoplastic Polyurethanes), and thermal plastic polymethlate, which is a linear embedded cluster composed of low polymer polymirol soft segments and diisocyanate-expansion hard segments.The TPU can be made of saliva, film blowing, pressure delay, or coating, which has the excellent characteristics of good elasticity, strong toughness, abrasion resistance, good cold resistance, and environmental protection and non -toxic.TPU fabric has the following characteristics:

1. Hardness planning wide

After changing the ratio of the components of the TPU composite fabric, the Tent cloth can get products of different hardness, and follow the hardness of the hardness. Its product still adheres to excellent elasticity and abrasion resistance.

2. High mechanical strength

The carrying capacity, impact resistance and shock absorption function of TPU composite fabric products are excellent.

3. Extremely cold -resistant

The glass state changing temperature of the TPU composite fabric is relatively low, and the canvas factory still adheres to excellent elasticity, softness and other physical functions at minus 35 degrees.

4. Good processing function

TPU composite fabrics can be processed with common thermoplastic materials, such as injection molding, extrusion, pressure extension, and so on.At the same time, the TPU composite fabric/cloth processing with certain polymer materials can obtain a polymer alloy with complementary functions.

5, oil resistance, water resistance, mold resistance.

6. Good recycled utilization.

There are two methods of TPU composite fabric. One is called and then sticked: first make it into a TPU film, then fit the glue with the fabric, and the other is called online composite: apply the glue on the fabric may not be glued.The fabric is made into a TPU composite fabric or clipped mesh.

Usually the material is formed by polyethylene, and the internal filling of foam plastic. According to the requirements of the regulations, it must be orange.

4. Lifeboat

Refers to a boat used to rescue the dangerous personnel.For example, a crew is settled and needed a small boat to rescue. At this time, rescue boats are generally used. One is that the rescue boat is good at maneuverability, and the second is that the rescue boat releases relatively quickly.The rescue boats used on the Ship are usually rigid, and the power is the out -of -out -of -out engine.The passenger Ship of the international route is equipped with 75%of the total number of members.At the passenger Ship of domestic routes, the entire Ship's lifeboat is equipped with 40%of the total number of members.

5. Safe raft

Determine the number of life rafts according to the number of passengers. Usually, the number of people with any life raft configured at any side is 1.5 times that of the number of crew members.Divided into rigid and qi -type life rafts. The rigid life raft has fewer applications. Most of the qi -type life rafts used on the merchant Ship. In short, it is a non -dynamic inflatable raft.When there is no inflatable, put it in a container. When needed, the compressed gas cylinder in the container quickly inflate the life raft.

6. Safe Floating Host

The passenger ships on class B are equipped with a total of 3%of the life -saving floats.
