Technical Field

[0001] The utility model relates to a self-rescue device for falling into water, in particular to a drone-mounted self-rescue device for falling into water, belonging to the technical field of drone mounting devices. Background Art

[0002] A drone is an unmanned device controlled by a radio remote control device and a self-contained program control device. Drones can perform dangerous tasks in various fields. However, when a drone is performing tasks over water and the airframe falls into the water due to unstable control and system, the drone will take in water and sink to the bottom, affecting recovery and reuse.

[0003] When the existing equipment protects drones from falling into water, the protection effect is poor; traditional self-rescue devices cannot effectively protect drones from the impact of water and the erosion of water on the self-rescue devices, resulting in damage and failure of the equipment and devices; due to the unreasonable structure, traditional self-rescue devices are not suitable for all drones and lack generality and adaptability. Summary of the Invention

[0004] To solve the deficiencies of the prior art, the purpose of the utility model is to provide a drone-mounted self-rescue device for falling into water.

[0005] To achieve the above objectives, the utility model adopts the following technical solutions:

[0006] A drone-mounted self-rescue device for falling into water includes a self-rescue box hung at the bottom of the drone.

[0007] In the middle of the box body, there is a longitudinal rotating shaft linked by the shaft of the motor, and a gear is sleeved on the rotating shaft.

[0008] In the box body, there is an airbag assembly linked by the gear.

[0009] The airbag assembly includes a baffle with an airbag on the outer side, and a rack for engaging the gear on the inner side of the baffle.

[0010] Sliders are arranged at the top and / or bottom of the baffle, and the sliders slide along the first chutes arranged horizontally on the top wall and bottom wall of the box body.

[0011] The side wall of the box body is provided with airbag holes matching the airbag.

[0012] An air pump for supplying air to the airbag is arranged in the box body.

[0013] A liquid sensor is arranged on the outer wall of the box body, and the control device opens and closes the motor and the air pump according to the feedback of the liquid sensor, and the power supply module is powered by the control device.

[0014] The above-mentioned airbag assemblies are in a pair. A pair of baffles are respectively arranged at both ends inside the box body. The racks that link the baffles are respectively engaged with the gears on both sides of the gears; the pair of baffles make opposite movements under the linkage of the gears.

[0015] Furthermore, the above-mentioned air pump is arranged between the baffles and supplies air to the airbag through a telescopic tube.

[0016] The above-mentioned self-rescue box is hung at the bottom of the drone through a plurality of clamping assemblies;

[0017] The clamping assembly includes a U-shaped frame arranged on the side wall of the self-rescue box. A pair of clamping blocks are respectively connected to the opposite inner side walls in the U-shaped cavity; among them, one clamping block is connected to the inner side wall through a pair of springs, and the other clamping block is connected to a screw rod passing through the inner side wall. A handle is arranged at the other end of the screw rod.

[0018] Furthermore, an arc-shaped clamp is fixedly arranged on the inner side surface of the above-mentioned clamping block.

[0019] Furthermore, a second sliding groove is arranged between the opposite inner side walls on the inner side wall of the above-mentioned U-shaped frame;

[0020] The end of the clamping block is matched with the second sliding groove and slides along the second sliding groove.

[0021] Still further, the cross section of the above-mentioned second sliding groove is T-shaped.

[0022] The beneficial effect of the present utility model is as follows:

[0023] A drone-mounted water-falling self-rescue device of the present utility model detects the state of the drone immersed in water through a liquid sensor. The control device opens and closes the motor and the air pump according to the feedback of the liquid sensor. The motor drives the rotating shaft to push the baffle to slide in the self-rescue box through the rack, pushes the airbag out of the self-rescue box, and at the same time, the air pump inflates the airbag. The buoyancy of the airbag makes the drone float on the water surface to complete self-rescue. Combined with the clamping assembly, the assembly and disassembly separation of the self-rescue box and the drone can be flexibly completed, which is convenient for the classified recycling of the drone and the self-rescue box, and is convenient for maintenance and repair, and has strong practicability and wide applicability.

Detailed implementation manners

[0029] The present utility model will be specifically introduced below in conjunction with the attached drawings and specific embodiments.

[0030] A UAV-mounted water rescue device includes a self-rescue box 3 hung at the bottom of the UAV 1.

[0031] As Figure 1 shown, 4 support tripods 2 are provided at the bottom of the UAV, and a pair are provided on each side of the self-rescue box 3, with a total of four clamping assemblies 5 that can clamp the support tripods 2; through the clamping assemblies 5, the self-rescue box 3 is hung at the bottom of the UAV 1.

[0032] The clamping assembly 5 is composed of a U-shaped frame, a pair of clamping blocks and a pair of arc clamps 19.

[0033] The U-shaped frame is composed of a back plate 16 and a pair of side plates 17. The U-shaped frame is fixed to the side of the self-rescue box 3 through the back plate 16. A pair of clamping blocks are placed in the U-shaped cavity and connected to the two side plates 17 respectively, and the connection methods are different. One of the clamping plates 18 is connected to the side plate 17 through a pair of springs 21, and the other clamping plate 18 is axially arranged at the end of the screw rod 22. The screw rod 22 is screwed to the side plate 17 and penetrates to the outside. A handle 23 is provided at the outer end of the screw rod 22. The arc clamps 19 are respectively arranged on the opposite surfaces of the clamping blocks, that is, the inner sides.

[0034] On the inner side surface of the back plate 16, a second chute 20 with a T-shaped cross section is provided horizontally. The end of the clamping block is placed in the second chute 20 and can slide along the second chute 20.

[0035] Preferably, an anti-slip pad is pasted on the inner side surface of the arc clamp 19.

[0036] The inside of the self-rescue box 3 is hollow. A rotating shaft 7 arranged longitudinally is provided in the middle of the box body. The rotating shaft 7 is linked by the shaft of the motor 6. Preferably, the motor 6 is arranged on the top wall of the box body. A gear is fixedly sleeved on the rotating shaft 7.

[0037] In the box body, a pair of baffles 9 are respectively placed at both ends and are mirror images based on the rotating shaft 7. The outer side surface of the baffle 9 is connected to the airbag 14, and the inner side surface is connected to the rack 8. The rack 8 is in tooth connection with the gear. The pair of racks 8 are respectively in tooth connection with the gear on both sides of the gear. That is, by rotating the gear, the rack 8 can move in opposite directions.

[0038] On the top wall or bottom wall of the box body, a first sliding groove 11 is provided. At the top and / or bottom of the baffle 9, a slider 10 is provided which can slide along the first sliding groove 11.

[0039] The airbag 14, the baffle 9, the first sliding groove 11, the slider 10, and the rack 8 form an airbag 14 assembly. The side plate 17 of the box body is provided with a bladder hole 15 corresponding to the airbag 14. Preferably, an air pump 12 is provided between the two baffles 9; the air pump 12 can supply air to the two airbags 14 simultaneously through a T-shaped telescopic tube 13.

[0040] The liquid sensor 4 is arranged outside the box body and is connected to the control device. The control device opens and closes the air pump 12 and the motor 6 according to the feedback of the liquid level sensor, and the power supply module is powered through the control device.

[0041] During use,

[0042] When the support leg frame 2 is placed in the U-shaped cavity of the U-shaped frame, the arc-shaped clamp 19 contacts the support leg frame 2.

[0043] Rotate the handle 23 clockwise to rotate the screw rod 22, thereby pushing the arc-shaped clamp 19 into close contact with the support leg frame 2, compressing the spring 21, and clamping the support leg frame 2 by the arc-shaped clamp 19 to fix the self-rescue box 3 on the support leg frame 2.

[0044] When the liquid sensor 4 detects that the self-rescue box 3 is immersed in water, the control device makes the motor 6 work according to the feedback of the liquid sensor 4. The motor 6 drives the rotating shaft 7 to rotate in the box body, and through the rack 8 meshing with the gear, drives the two push plates to slide away from each other along the first sliding groove 11 through the slider 10, so that the airbag 14 on the baffle 9 moves outside the self-rescue box 3.

[0045] At the same time, the air inflation pump 12 starts to work, and inflates the airbag 14 through the telescopic tube 13, and the airbag 14 unfolds after being inflated.

[0046] That is, when the unmanned aerial vehicle 1 falls into the water, the buoyancy of the airbag 14 can be used to make the unmanned aerial vehicle 1 float on the water surface, realizing self-rescue when the unmanned aerial vehicle 1 falls into the water, extending the floating time of the unmanned aerial vehicle 1, so that the rescue personnel can salvage it in time.

[0047] When the personnel arrive, the handle 23 can be rotated counterclockwise, so that the clamping plates 18 fixing the support leg frame 2 move away from each other, and the self-rescue box 3 can be disassembled from the unmanned aerial vehicle 1 for the later maintenance and repair of the self-rescue box 3 and the equipment inside.

[0048] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form. Any technical solutions obtained by using equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
