1. How long can the Underwater propeller battery be used?

Underwater pusher uses lithium batteries.Because lithium batteries have the advantages of small size, light weight, high energy density, long service life, no memory effect, environmental protection, safety and reliability, etc., so far they can use one of the most widely used battery products on military and civilian products.So how long can the Underwater pusher battery be used?

The lithium battery of the Underwater propeller is generally about two years. Lithium batteries are mainly based on aluminum alloy materials and batteries using non -hydraulic solution.Therefore, when used, if the lithium battery is often full of electricity, the lithium inside runs to the negative electrode in the battery, which cumulates too much to cause the crystal phenomenon of the negative version, thereby reducing the battery capacity of the lithium battery.Basically, it is equivalent to shortening the life of the battery.

2. How to change the battery Underwater propeller

The previous article has briefly understood how long the Underwater pusher battery can be used, and then let's take a look at how to change the battery Underwater pusher!

1. Turn off the power switch of the Underwater pusher.

2. Open the battery warehouse cover of the Underwater pusher and remove the old battery.

3. Put the new battery in the battery warehouse.

4. Close the battery warehouse cover to ensure the seal.

5. Connect the power cord, turn on the power switch, and check whether the battery works properly.

PS: (When replacing the battery, please ensure that the battery contact and battery compartment battery contacts are dry and clean in the dry environment.)

1. Basic sprint training training

1, Spinal strength (analyzing the functional disorders of the body)

2, Model mode training: physical posture, legs and knee -knee stretching movements (hip opening), arm movement (the shoulder joints must be flexible, the more the arm swinging amplitude, and the larger the amplitude of the lower limb movement)

3, Training in large core areas (the principles of pelvis, thorax, hip joints and the entire spine, cylinder principle)

4, Power Training (General PowerSpecial force)

2. Training method training method

1, Frog jump: Be careful to jump continuously without staying in the middle.Try to jump as far as possible, but don't rush to achieve success. Generally30arrive50About rice, enhance the practice of thighs and basic forces.

2, Jumping steps or stairs: You can jump with one foot, feet, and jump continuously. It is best to wear a leg protection when jumping. Be careful to scratch your calf (enhance the explosiveness of the thighs and the speed of the calf).

3Steak: The spare time can use this simple movement to enhance the toughness and strength of the ankle joint.

4, Live high -lifting and high legs: Find a barbell or other load -bearing things (you can buy a secondary sandbag to tie your legs, the weight is suitable for you), quickly high -lifting, increase the comprehensive ability of the thighs.

5, run back: Find the wall or double bar, hold your hands, your body and the ground become45--60At the angle, quickly exchange your legs. Pay attention to the support of the legs and move your legs as much as possible.

6Running: run with leg tied sandbags.Garway Running: one time Running600rice or800rice.The straight road is at full speed, jogging or walking.

3. How to carry out sprint training plans

1When Running at the beginning, it is not easy to train too much. It takes a step -by -step, the strength is restored, and the muscle adaptation training stage takes about a week.

2Before exercise, you must take jogging warm -up to prevent exercise from injury.Cross -legged steps should be quickly and improve the muscle strength of the calves (this is the key to Running fast). It is done in five groups daily.

3, Highly lift your legs and send cross -exercise exercises. The steps must be large, increase the amplitude of the swing, the Running posture must be standard, and the spring rope is pulled forward to improve the waist and abdomen power.

4After 20 meters of frog jet, accelerate the Running, increase muscle explosive power, chase between athletes, and improve training fun.I believe that these methods will adhere to one month, and your grades will make progress rapidly.

Fourth, sprint training skills

1, Starting stage

The focus of the human body should be higher and at the front of the support point, which is conducive to acceleration.

The characteristics and structure of the action are as follows

FootThe foot distance (the distance from the back of the toe to the front foot is personalized)

Ankle jointEx to the greatest extent, appointment45Spend

Knee angle90120Spend

Hip heightPest by person

Starting movement: The power of the lower limbs and the upper limbs is sufficient, and the shoulder joint muscles are developed.When the Running is accelerated, the back of the back is straight, the arm and the shoulder joint are very flexible, the angle between the legs is very large, the hip joint is fully opened, and the ankle joint is fully stretched.

2, Accelerate stage

Accelerate goals: Maintain a balanced body posture to consume less energy and achieve maximum speed as soon as possible.

Accelerated Running action characteristics:

Physical posture (leaning forward45-55Spend)

Placing legs (hip and formation90Degree, the knee joint is smaller than90Degree, tight ankle joint)

Arms movement (elbow joint90110Spend)

Participate muscles: hip and knee joints participating in exercise (quadriceps and gluteal muscles), ankle joint and toe strength (gastrocity muscle and anterior tibia)

Explosive starting training is required to produce strength through the common effects of the hip, knee, and ankle, because the rapid starting technical requires the hip and knee tissue to have great elasticity.Good hip power helps athletes to separate their legs when the knee is raised. When contacting the ground, the elastic power reduces the power of the knee and hips, while reducing the time for contact with the ground.Starting ability training can help athletes provide the maximum acceleration ability.Starting training includes starting exercises in various poses, short -distance acceleration exercises, and sprint assistance technology exercises.

3, Transitional stage

The transition to the upright body posture and maintaining the speed of the acceleration stage, the transitional stage still needs to increase the power of the ground. The speed has been accumulating.2040The speed of the rice interval has been increasing.

Objectives to be achieved: By improving the movement economy of Running, reducing the rotation movement of the body during the Running process (the feet kick back and outside the outside, swing back and outer sides of the abdomen), maximize the rapid Telescope of muscle and nerves.The reaction ability makes the body reach the maximum speed.

4The absolute speed stage

The body leaning forward is not to run faster, but to maintain speed.The acceleration stage emphasizes the kicking action, and the maximum speed stage emphasizes"Cutting on the ground" action

Physical posture: Keep your body upright posture (shoulder to your hip, your hip to ankle is out of the ankle)

5. precautions for sprint training

1Do a good job of preparing activities before exercise.Track and field movement can easily cause muscle, joints, and ligament damage, especially the chance of injury to the lower limbs.The only way to prevent is preparation activities before the game.The more fully the preparation activities, the less easily injured.On the basis of jogging, the shoulder joint, elbow joint, back waist muscles, legs, knee, ankle joints and other parts are activated to strengthen the strength of muscle and ligaments, improve the sensitivity and coordination of the body, and prevent injuries.Essence

2, Before exercise or game, students should pay attention to maintaining good sleep and physical savings. Before the game, they should control too much diet and drinking water, let alone drink.

3After exercise or competition, you should do a good job of relaxing activities to restore physical and muscle strength as soon as possible.The method is to relax and beat each part of the body, massage each other, and massage each other.

4When the whole body is hot, take off the coat. After Running, you should put on the coat immediately to prevent the wind from the wind.The shoes and socks worn during long -distance Running should be soft and feet.

6. Relax after sprint training

1Relax of muscle groups on the back of the calf

The calf rear muscle group (than the fisheyle muscle, the gastrocnemiosus) relaxes, the foam shaft is placed on the calf13The position of Zusanli, the hand can45You can also support it ahead.Get rolled to the position of the knee nest and came back to the top side of the ankle.

2, Relax of muscle groups on the back of the thigh

From the top of the knee, the four -headed muscle of the stock, rolling to the lower edge of the buttocks.Adjusting the position of the support hand can increase the amplitude.Note all the power to add to the leg you relaxed.

3, Relaxation of the tibia of the calf

Kneel on the foam axis and roll to the upper side of the ankle joint. Note that it is easy to put the strength on the tibia.

4, Relax of the quadriceps of thigh stock

Because the load required for the quadriceps of the thigh stock is very heavy, everyone knows that it is such a large muscle group on the upper side of the knee, so in the process of Running, especially in the process of Running the mountain, the quadriceps muscle must be done.Many, let's take a look at a lot of excellent runners. The volume and volume and lines of thigh stocks are very large.

5, Relax

The iliac tibial beam is the deep fascia around the thighStidal part of the outer side of the wide fascia.The outer edge of the iconic part,,It is divided into two layers,,Wrap wide fascia tension,,And closely combined with it should not be separatedThen, thenThe vertical fiber in the lower part is significantly thickened and flat -shaped,,The rear reed of the gluteal muscle tendon continuesThen, thenThe lower end of the tibial tibia is attached to the outer tibia, fibula head and knee capsule.Clinically, the iliac tibial beam is often used as a repair and reconstruction material for the repairs and reconstruction of the body wall defect, weak parts or knee cross -ligament damage.

6Relax of upper and lower back

If you are uncomfortable on the top, the lower back feels uncomfortable, for example, many people have the posture of pot and waist when they are Running. After a long distance, the whole shoulder is unwell, or many Desks work more.The neck and spine are helpful.

1. Why should the surfing board wax

surfing board is a Tool for our entertainment. Of course, no matter how good the surfing board is, it is also necessary to wax. The waxing surfboard can effectively increase the friction of the human body and the body.Sitting on the surfboard is easier to sit straight.

surfing plate wax (non -slip wax) is a special wax, mainly composed of wax, vegetable oil, pine fat, resin and natural essential oil.Generally, two waxes, bottom wax and facial wax.3a2418-24Water temperature is 14-18 C), and the cold water wax (below the water temperature below 15 C).

2. How to maintain and clean the surfboard

To make the surfing board play the greatest role, it is essential for maintenance and maintenance. So how to maintain and clean the surfboard?

1. surfing plate cleaning

Rinse and wipe it after each use. The sea water will cause considerable damage to the completeness of the surfing plate, especially when it suffers from some collisions and impacts, the salt section will cause damage from the inside through the small wound of the salt.Rinse with fresh water after each surfing.This is easy to achieve, and it will not take up too much.

In addition to rinse, deep cleaning is needed after several surfing.Depending on where you surf and the frequency of stay in the water are maintained in different ways.

2. surfing maintenance

(1) Ready to open board

The first step is always the most challenging.The first step is to confirm that there are no old, sand and dirty wax on the board.It takes a little time to clean up the old wax and place the surfboard in a sunny place.The sun helps to soften the wax.In this way, it is easier to melt and harden.With no sun, you can use hair dryers. Whether it is from the sun or a hair dryer, pay attention to the heat.

(2) Cut the diagonal line with a wax comb

Before waxing, scrape the wax on the surfboard with the knife surface of the wax comb and clean it with cloth. If you can't find a wax comb in a while, you can get a plastic card or replace the wax comb.The surface layer was scraped almost some warm water on the board.Softening the residue in warm water, wipe it off with a wet cloth.

(3) Use a surfboard to clean spray

After the warm water is cleaned, there will be some residues on the plate. In order to clean it more thoroughly, you can use a surfboard to clean the spray.Apply the surfing plate evenly, and finally wipe it clean according to the use time on the instruction manual.

(4) Apply with coconut oil

The last step is to completely wipe the entire surfboard.Apply a thin layer of coconut oil to protect the body.Apply a layer of fresh wax or fine processing spray after air drying.

[How to save self -rescue at sea] How to save self -rescue and rescue methods on the sea of self -rescue at sea

How to save self -rescue at sea Self -rescue and rescue methods at sea

1 Generally speaking, it is not encouraged to jump first, because in the water, the body temperature of the human body is lost quickly, and it may be taken away by the water.Under the circumstances of environmental permission, you can skip the boat, pay attention to avoid the shallow beach reef.To quickly leave the shipwreck, if the Ship is covered, you must jump to the head of the bow.

2 Once the water falls, be sure to leave the hull quickly to prevent the vessels from being inhaled again.At the same time, you should raise your head to tilt your body.After maintaining this attitude for a few seconds, you can slowly float on the water with the powerful buoyancy of the life jacket.

3 Do not make unnecessary swimming after falling into the sea, to save physical strength and wait for rescue.

4 Creation of swimming will be rescued!When the Ship is sinking, the sucking power will be generated. Paralying, the place where the fluid is high at a high speed, and the sinking Ship is slightly stronger. Pressing people around the Ship, can't get out, and make people drown.

5 Self -rescue methods that do not swim: When sinking down, keep calm, close your lips, bite your teeth and hold your breath. Do not struggle in the water.Slowly float on the water.After floating on the water, do not lift your hand out of the water, and place it under the water to keep your head above the water surface so that you can breathe air.

6 The most important thing is to maintain physical strength. When someone comes to rescue, use the whistle and reflective equipment on the life jacket to attract the attention of the rescue staff.

Method for forced to drift on the sea

1 , Warm with your companions

When encountering the drifting condition, if the companions are around, they will match each other to warm the back to maintain the body temperature.

2 , Use the mirror reflection principle to create signals

Use metal items floating at sea as a reflector.The slightly shaking mirror allows the reflected light flash to intermittent, attracting the attention of search and rescue personnel.

3 , Avoid sunburn

Surviving on the sea, sunburn is a question worthy of face -to -face.We must avoid direct contact with the sun with the body, and try to find a paste from the first aid tools to isolate the damage caused by the sun to the Skin to prevent the occurrence of sunburn.In addition, the reflected strong light brought from the sun to the water surface is also a sunscreen element that cannot be ignored. Therefore, the head and eyes must be careful of the damage caused by such strong light.

4 , Avoid dehydration

Galmic (sea) may increase the occurrence of dehydration.To survive on the sea, in order to avoid dehydration, we should try to reduce the number of times to go to the toilet and keep ourselves in the body. If you feel uncomfortable, try not to make ourselves more comfortable by vomiting.

5 , Avoid the trouble of blindness and head damage

If you are infected with flames, cigarettes or other pollutants on the water, we must first wash the pollutants with salt water and then rinse it with fresh water.Eye cover18 to twenty four Hours, even longer.In order to avoid strong light from the sky and water harm your eyes, if you are prepared, wear Sunglasses to protect your eyes.

6 , Pain caused by salt water

Soaking in the body for a long time may cause the Skin wound, and the original blisters or scars on the body may be thick or torn again. At this time, in addition to avoid touching the wound, we must use fresh water to rinse it.EssenceIf possible, keep the wound dry and use the desiccant.

7 , Keep physical energy (1)

The loss of body fluid and exhaustion of physical strength will cause more damage.If you start to feel a halo, start vomiting, try to change the place, and stay away from vomit and smell.

8 , Keep physical energy (2)

Do not deliberately rely on exercise to maintain body temperature. Instead of deliberately circulating, the body temperature is easier to lose, and the exhaustion will make it easier for us to accelerate the temperature loss of the body in cold water.Maintaining buoyancy and using various kinds of materials is the best way to save self -help.

If the waves on the sea, if you do not wear water and lung Diving equipment, you may not be able to breathe at sea and the method, then according to the following practice:

Step 1: Take a deep breath.Step 2: Put your face in the water, close your mouth, stretch your arms forward, and relax.Step 3: Keep this posture rest.Step 4: Looking out of the water, stepping on the water, and venting the head into the water.Such a cycle.

9 ,keep Calm

Keep your head calm, do not shout without any help, and do unknown and physical action.

The importance of field emergency courses

At any degree of field emergency courses, it is helpful to outdoor activities, just like the concept of buying insurance.What's more valuable is that wild emergency technology can reduce risks as soon as possible.

The content of the first aid package must be commensurate with your field first aid knowledge: First of all, the item of the first aid packaging must be what you know how to use, if you don't know or not be sure how to use it.Then, the larger the first aid package, the greater the burden on you.

In fact, in the field of field first aid, it is more important skills to correctly judge the patient's symptoms, and this ability must be achieved through the wild emergency courses. Therefore Good guarantee.As for the degree of participating in the field of emergencyly, it depends on the degree of participation in field activities.

precautions for Outdoor emergency emergency first aid

The rescue time at the scene is urgent. For the treatment of severe condition, one must abide by the principle of first aid, and the other must grasp the key points, accurately judge, and quickly follow the following steps to check the patient. If necessary Essence

1. Judgment consciousness

Pat in the patient's shoulder (or face), and call in his ear loudly: "Hey, what's what are you!" Try to react, the baby uses the heel or the harmony of its valley. If you can cry, it will be consciousEssence

2. Call for help loudly

The patient had no response to light patting and calling, showing that he was unconscious and immediately shouted loudly in place: "Come on! Help!"

3. First aid position

The patient's position should be "lying on the hard plane".If the patient is prone or sideways, he should flip him into a supine and place it on a hard plane, such as wooden beds, flooring or back pads on wooden boards, so that the heart can be squeezed effective.Patients should not lie on the soft objects, such as sofa or spring beds, so as not to directly affect the effect of the heart squeezing of the chest.Pay attention to protecting the head and neck.

How to turn over: The rescuer first Kneeling on the shoulder and neck of the patient on one side, straightening the upper limbs in the head, and then placing the remote calf from the rescuer on the close leg, cross the legs, and then cross the leg.Use one hand to hold the patient's back and neck, and hold the patient's remote armpits, so that the head, neck, shoulders, and trunk is turned into an upper position as a whole. FinallyBack to the sides of the body.

4. Open the airway

The rescuer's deduction, tie tie, scarf, etc. of the patients quickly cleared the sludge, soil, sputum, vomit, etc. in the patient's mouth, nose, and nose to facilitate the Smooth respiratory tract.The respiratory tract is a must for gas to enter and exit the lungs.Because the consciousness loses the patient's tongue muscle relaxation and the back of the tongue, he will be tired of falling.Raise your head and lift the mandibular Bone, move the throat wall back and widener the airway, make the airway open, and breathe smoothly.The rescuer put one hand in the patient's forehead and pressed down, so that his head was leaning back, and the index finger and middle finger of the other hand were placed near the mandibular Bone near the mandibular part, lifting the pupae forward to help the head lean back.The connection between the jaw angle and the earlobe below the back of the head to be vertical and vertical to the ground.The baby's head is gently leaned back.

Note that the foreign body in the oral cavity should not take up too much time. The entire open airway process must be completed within 3-5 seconds, and during the whole process of cardiopulmonary resuscitation, the airway must be unobstructed from beginning to end.

5. Seeing, listening, feeling breathing

After the patient's airway is unblocked, the rescuer uses the method of watching, listening, and feelings for 3-5 seconds to check whether the patient has an auto breathing.Examination method: The rescuer stiches the patient's mouth and nose with his ears on the side. Seeing the patient's chest (or the upper abdomen), there is an ups and downs; the sound of the breath of the patient's mouth and the nose is the sound of air flow;

6. Artificial breathing

If the patient has no autonomous breathing, the rescuer should immediately perform artificial breathing on the patient -two times (nose) blowing air.Each time blowing time is 1.5 seconds.The amount of gas blowing should be 800 ml each time.

7. Check the pulse and judge the heartbeat

The rescuer uses a touches of the carotid arteries or the aeral artery to observe whether there is a fight for 5-10 seconds to determine whether the patient has a heart beating.You should touch it gently during inspection and do not press hard.In order to judge accuracy, bilateral carotids can be touched, but it is forbidden to touch both sides at the same time to prevent blood supply to the brain.If there is no pulse beating, the chest heart extrusion can be performed, squeezing 15 times, and the squeezing speed is 60-80 times per minute.The ratio of squeezing gas to blowing is 15: 2.After four consecutive or 1 minute, judge, check the pulse, respiratory recovery, and pupils.

8. Urgent hemostasis

For those who have severe trauma, the rescuers should also check whether the patients have severe bleeding wounds. If so, emergency hemostatic measures should be taken.Avoid death caused by shock caused by major bleeding.

9. Protect the spine

Severe trauma caused by accidental injuries and emergencies. During the treatment, pay attention to protecting the spine and moved by medical supervision.Avoid further aggravation of spinal cord injury or injury spine, causing paraplegia or even death.
