[0002] Drowning is a common type of accident, especially in summer, when there are often many people playing in the water in rivers, lakes and reservoirs in cities, and accidents can easily happen. In the process of searching and rescuing drowning people on the surface of natural lakes or oceans, traditional rescue methods mainly rely on rescuers carrying life-saving equipment to approach and rescue. The rescue process is difficult, requires high physical endurance from lifeguards, and is somewhat dangerous.

[0003] The existing underwater rescue devices generally use a propulsion mechanism to drive an uninflated airbag close to the drowning person, and then separate from the airbag. The airbag is inflated by a high-pressure gas cylinder to make the airbag float and bring the drowning person to the surface. However, the problem that the drowning person loses consciousness or cannot actively grab the lifebuoy in the drowning state has not been solved; and the current underwater rescue devices cannot fold and organize the airbag. When the airbag is in an uninflated state, its underwater state cannot be controlled, which to a certain extent will cause unnecessary drag and resistance during underwater rescue, or there is a risk of blocking the shooting module on the underwater propulsion mechanism, resulting in the rescue personnel being unable to accurately judge the state and position of the drowning person through the shooting information, delaying the rescue operation, and there is a risk of endangering the life safety of the drowning person.

In the above, the radial line of the inflatable airbag 11 refers to a ray extending outward from the center of the inflatable airbag 11. The support assembly includes a first fixed block 12, a second fixed block 13, an elastic rubber strip 14 and a telescopic adjustment member. The side walls of the first fixed block 12 and the second fixed block 13 are respectively bonded to the outer side walls of the inner diameter and the outer diameter of the inflatable airbag 11. The sides of the first fixed block 12 and the second fixed block 13 that are close to each other are respectively fixedly connected to the two ends of the telescopic adjustment member, and the sides of the first fixed block 12 and the second fixed block 13 that are close to each other are respectively rotatably connected to the two ends of the elastic rubber strip 14. A magnetic block 17 is provided on the side of the second fixed block 13 that is away from the first fixed block 12. A plurality of connecting members for locking the position of the magnetic block 17 are provided on the telescopic mechanism 2, and the plurality of connecting members correspond to the plurality of magnetic blocks 17 respectively. The first fixing block 12 and the second fixing block 13 are rotatably connected to the two ends of the elastic rubber strip 14 on one side close to each other, and an embedded rotating structure can be adopted. The method adopted is that a ring bearing made of metal or hard plastic is embedded in the elastic rubber strip 14, and the ring bearing is embedded in the groove on the side wall of the second fixing block 13 to realize the rotation function; specifically, the outer ring of the ring bearing is fixed by tightly bonding with the elastic rubber strip 14, and the inner ring is placed in the machined groove on the second fixing block 13, so as to ensure a low-friction rotating fit between the two. Specifically, Figure 6 , Figure 7 , Fig.15 As shown, the telescopic adjustment member includes a first movable rod 15 and a second movable rod 16, one end of the first movable rod 15 is fixedly connected to the side wall of the first fixed block 12, the other end of the first movable rod 15 is provided with a sliding groove matching the outer side wall of the second movable rod 16, one end of the second movable rod 16 is slidably arranged in the sliding groove, and the other end of the second movable rod 16 is fixedly connected to the side wall of the second fixed block 13; The elastic rubber strip 14 is provided with a slot 113 on one side adjacent to the first movable rod 15, which matches the outer wall of the first movable rod 15.
