[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1:

[0027] Figure 1-3 As shown, the present invention provides a foldable flying rescue board, including a float 1, a folding device 2 and a rotor assembly 3, wherein the float 1 includes a float 11 and a float 12, the folding device 2 includes a sleeve 21 and a sleeve 22, the float 11 is inserted and fixed in the sleeve 1 21, the float 2 12 is inserted and fixed in the sleeve 22, the sleeve 1 21 and the sleeve 2 22 are rotatably connected by a hinge 25, and the rotor assembly 3 is respectively installed at the opposite ends of the float 11 and the float 2 12;

[0028] During rescue, the sleeve 1 21 and the sleeve 2 22 are rotated and opened to the same straight line, and the buoy 1 11 and the buoy 2 12 form a long rod-shaped structure, and then the rotor assembly 3 is controlled to fly and land, and multiple people to be rescued can stay afloat on the water by climbing on the middle position of the rotor assembly 3 to avoid continuous drowning, so as to achieve rapid rescue of multiple people drowning at the same time;

[0029] In addition, when storing, the sleeve 1 21 and the sleeve 2 22 are folded in half to reduce the length and optimize the storage space, making it easier to store and carry.

[0030] A hinge groove 1 23 and a hinge groove 24 are respectively preset on the sleeve 1 21 and the sleeve 2 22. The hinge groove 1 23 and the hinge groove 24 are connected and used to set and store the hinge 25. At the same time, a lock buckle groove 1 26 and a lock buckle groove 27 are respectively preset on the sleeve 1 21 and the sleeve 2 22 on the side away from the hinge 25. The lock buckle groove 1 26 and the lock buckle groove 2 27 are aligned and connected. A female buckle and a sub buckle are respectively arranged in the lock buckle groove 1 26 and the lock buckle groove 2 27;

[0031] When the folding device 2 is rotated to open, the mother buckle and the child buckle are locked together to achieve stable unfolding of the flight rescue board. At the same time, the arrangement of the hinge groove 1 23, the hinge groove 24, the lock groove 1 26 and the lock groove 2 27 avoids the protrusions of the hinge 25 and the mother buckle and the child buckle, thereby reducing the possible scratch damage to people when climbing.

[0032] (The following structure is simple and is not shown in detail in the figure) In addition, aligned through holes are provided on the folding device 2 and the floating body 1, and long bolts are inserted into the through holes and used with nuts to lock the floating body 1 and the folding device 2. Embodiment 2:

[0033] The difference from the first embodiment lies in the locking device 4 used to lock the folding device 2 and the floating body 1, which is as follows:

[0034] like Figure 4 As shown (a simple structural schematic diagram is used for ease of understanding), a fixed shaft 41 is coaxially fixed in both the sleeve 1 21 and the sleeve 2 22, a fixed ring 42 is coaxially fixed to one end of the fixed shaft 41 away from the bottom, and a moving ring 43 is slidably sleeved on the other end, and at least one strut 1 44 is hinged on the fixed ring 42, and the same number of struts 2 45 as the struts 1 44 are hinged on the moving ring 43, and the hinge axes of the struts 1 44 and the struts 2 45 are perpendicular to the fixed shaft 41, and the movable ends of the struts 1 44 and the struts 2 45 are hinged to the same pressing plate 46, wherein the fixed shaft 41, the fixed ring 42, the moving ring 43, the struts 1 44, the struts 2 45 and the pressing plate 46 constitute a locking device 4, and at the same time, a cavity 13 is preset at one end of the buoy 1 11 and the buoy 2 12 and extends inward;

[0035] When float 11 and float 2 12 are inserted into the folding device 2, the movable ring 43 is away from the fixed ring 42, and the folding device 2 can extend into the cavity 13, and then the movable ring 43 is controlled to move toward the fixed ring 42 until the pressure plate 46 is squeezed with the inner wall of the cavity 13, thereby locking the movement of the float 1.

[0036] At the same time, a connecting rod 47 extends from one side of the movable ring 43 away from the fixed ring 42, and the connecting rod 47 extends to penetrate the folding device 2, and a power plate 48 is fixed to the end of the connecting rod 47. In addition, a thrust spring 49 is sleeved on the connecting rod 47, and the thrust spring 49 is located between the power plate 48 and the folding device 2;

[0037] When the folding device 2 is in the folded state, the thrust spring 49 is in a relaxed state, and the supporting power plate 48 enables the moving ring 43 to be kept away from the fixed ring 42, so that the pressure plate 46 is away from the cavity 13, and the floating body 1 can be disassembled and assembled; and when the folding device 2 is unfolded, the power plate 48 is squeezed, and the moving ring 43 is synchronously gradually approached to the fixed ring 42 until the folding device 2 is fully unfolded, and a certain squeezing force is formed between the pressure plate 46 and the inner wall of the cavity 13, thereby locking the movement of the floating body 1. In order for the folding device 2 to be fully unfolded, a storage groove 30 is preset on the folding device 2, and the storage groove 30 can fully accommodate the power plate 48 and the thrust spring 49, and at the same time, the squeezing and fitting between the power plate 48 and the storage groove 30 can effectively prevent water from entering through the gap.

[0038] The working principle of the present invention is:

[0039] Rescue preparation: different lengths of the float 1 can be selected according to the number of rescuers. The float 1 is simply inserted into the folding device 2, and the folding device 2 is unfolded, so that the float 1 is fixed in the folding device 2 simultaneously.

[0040] Then, by controlling the rotor assembly 3 to fly and land, multiple people to be rescued can climb to the middle position of the rotor assembly 3 to stay afloat on the water to avoid continued drowning, thereby achieving rapid rescue of multiple people drowning at the same time.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
