[0002] With the increasing number of water activities, water safety issues have also attracted more and more attention. In water rescue, the performance of life-saving equipment is crucial. A water life-saving backpack came into being, aiming to provide more reliable and efficient rescue protection for people who fall into the water. This life-saving backpack is exquisitely designed and can quickly play a role in an emergency, buying precious rescue time for people who fall into the water;

[0003] At present, traditional water rescue equipment mainly includes lifebuoys, life jackets, etc. These equipment are usually made of buoyant materials, which can make the drowning person float on the water surface by providing buoyancy. During use, the drowning person needs to actively grab the lifesaving equipment or wear it on his body to float himself out of the water;

[0004] Traditional equipment has great limitations when it comes to floating a drowning person to the surface of the water. The drowning person needs to hold on to the life-saving equipment for a long time, which not only consumes a lot of physical strength of the drowning person, but also when the water flow is turbulent, the life-saving equipment is easily overturned by the water flow, causing the drowning person to fall into the water again, which poses a great threat to the life safety of the drowning person and also brings great difficulties to the rescue work. Therefore, an aquatic life-saving backpack is proposed to solve the above problems. Summary of the invention

[0005] In order to make up for the above shortcomings, the present invention provides a water life-saving backpack, which aims to improve the problem that when traditional equipment floats the drowning person to the water surface, the drowning person needs to hold the life-saving equipment for a long time, and when the water flow is turbulent, the drowning person is easily knocked over, causing him to fall into the water again.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

One side of the sub-airbag 3 is fixedly connected to a self-adhesive tape 4, and the other side of the sub-airbag 3 is fixedly connected to a self-adhesive tape 2 5, self-adhesive tape 1 4 and self-adhesive tape 2 5 are made of durable nylon material, which has strong viscosity and can maintain good adhesion effect in water, ensuring that the sub-airbags 3 are firmly connected, and the outer wall of the sub-airbag 3 is provided with a connecting component, and the connecting component is used to enhance the stability of the connection between two adjacent sub-airbags 3.

[0033] Specifically, in the specific use of the device, firstly, the two adjacent sub-airbags 3 need to be tightly adhered, and the two adjacent sub-airbags 3 are adhered by the self-adhesive tape 1 4 and the self-adhesive tape 2 5, and then the device is thrown into the water. After the device enters the water surface, it will trigger the automatic inflation valve 9. The automatic inflation valve 9 is a high-precision mechanical device that can sensitively sense the pressure changes of the water. Once the device enters the water, it will quickly open and inject gas into the main airbag 2 and the sub-airbag 3. Under the injection of gas, they will quickly expand into a circle, and at this time the device will slowly float to the landing with the water flow. The drowning person can enter the top of the main airbag 2 and use the buoyancy of the main airbag 2 and the sub-airbag 3 to steadily lift the drowning person out of the water. After being inflated, the main airbag 2 and the sub-airbag 3 present a spherical tumbler structure as a whole. Due to its unique shape and center of gravity distribution, it will not be easily overturned by wind and waves even in rapids or rough seas. Even if it is overturned by huge waves, it will quickly turn right due to gravity, ensuring that the drowning person is always in a safe state. If the sub-airbag 3 accidentally gets water in the drifting process, the self-adhesive tape 1 4 and the self-adhesive tape 2 5 can be torn off. The design of the self-adhesive tape facilitates quick operation in an emergency, allowing the user to clean out the water in time to ensure that the weight of the equipment is not increased due to the entry of water, thereby affecting its buoyancy and stability. Then, the person who falls into the water can use the rescue items inside the storage bag 8 to ensure his own safety and transmit rescue signals. When rescue equipment such as a lifeboat or an airplane finds the person who falls into the water, one end of the rope 22 is firmly fixed to the rescue equipment, and the pull ring 7 at the other end is fixed to the inner wall of the fixing ring 6. The person who falls into the water is rescued by pulling, thereby successfully rescuing the person who falls into the water from danger.

[0034] Reference Figure 3 and Figure 4The connecting component includes a shell 11, which is made of high-strength plastic material with certain toughness and corrosion resistance. The surface is specially treated to be smooth and not easy to wear. The shell 11 is arranged on the two of the sub-airbags 3, and the outer walls of the sub-airbags 3 are fixedly connected with a plurality of connecting belts 10, and the connecting belts 10 are fixedly connected to the outer wall of the shell 11. A movable groove 19 is opened inside the shell 11, and the inner wall of the shell 11 is fixedly connected with a push plate 14, and the outer wall of the push plate 14 is fixedly connected with a limiting block 15. The limiting block 15 is made of plastic, and the internal structure is reasonably designed, which can effectively limit the semicircular slider 13 to prevent it from deflecting during the rotation process. The limiting blocks 15 are fixedly connected to the inner wall of the shell 11, and the inner wall of the limiting blocks 15 is rotatably connected with the semicircular slider 13. The semicircular slider 13 is made of wear-resistant plastic, and the surface is finely processed with high smoothness, which can be The interior of the limit block 15 rotates smoothly, and one side of the semicircular slider 13 is fixedly connected to a control rod 12, which is made of high-quality plastic material, is sturdy and durable, and can accurately transmit force. The control rod 12 is slidably connected to the inner wall of the moving groove 19, and a baffle 16 is arranged inside the control rod 12, and the baffle 16 is fixedly connected to the inner wall of the shell 11, and the outer wall of the control rod 12 is fixedly connected to a sliding column 21, and the outer wall of the sliding column 21 is slidably connected to a fixed column 17, and the interior of the fixed column 17 is smooth, which can provide good guidance for the sliding of the sliding column 21, and the fixed column 17 is fixedly connected to the inner wall of the shell 11, and the outer wall of the fixed column 17 is fixedly connected to a spring 18, which has good elasticity and fatigue resistance, and can quickly return to its original state after compression, so as to provide power for the resetting of the semicircular slider 13, and the spring 18 is fixedly connected to the outer wall of the control rod 12.

[0035] Specifically, when the drowning person enters the top of the main airbag 2, the shells 11 on both sides can be moved to the opposite side. The design of the shell 11 can protect the internal components without adding too much weight.

[0036] Working principle: When using the device, firstly, two adjacent sub-airbags 3 are adhered by self-adhesive tape 1 4 and self-adhesive tape 2 5, and then the device is thrown into the water. After the device enters the water surface, the automatic inflation valve 9 is used to inject gas into the main airbag 2 and the sub-airbag 3 to expand them into a round shape. The device floats to the drowning person with the water flow. The drowning person enters the top of the main airbag 2 and is lifted up from the water by the main airbag 2 and the sub-airbag 3. After the main airbag 2 and the sub-airbag 3 are inflated, they are in a spherical tumbler structure as a whole. The rescue equipment 22 is fixed to the rescue equipment, and the pull ring 7 at the other end is fixed to the fixed The inner wall of the ring 6 is pulled to rescue the drowning person. When the drowning person enters the top of the main airbag 2, the shells 11 on both sides can be moved to the opposite side, and the push plate 14 on one side is used to squeeze the semicircular slider 13 on the other side, so that the semicircular slider 13 rotates inside the limit block 15. During the rotation of the semicircular slider 13, the spring 18 is compressed through the control rod 12, and the slide column 21 slides inside the fixed column 17. The slide column 21 is used to limit the slide column 21 to prevent When the semicircular sliders 13 on both sides overlap, the rebound force of the sliding column 21 is used to drive the semicircular slider 13 to rotate, so that the convex surface of the outer wall of the limit block 15 is used to block the semicircular slider 13 to prevent it from moving, thereby achieving a fixed connection between the two shells 11, thereby enhancing the stability of the connection between the two adjacent sub-airbags 3, preventing the self-adhesive tape 1 4 and the self-adhesive tape 2 5 from being loosely adhered, causing the two connected sub-airbags 3 to be disconnected, and enhancing the use effect of the equipment.
