DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] Reference Figures 1-7 As shown, a water tank battery cooling system for a drone includes a water tank 1 and a battery body 4, wherein a protective shell 11 is provided in the water tank 1 for placing the battery body 4, a processing shell 12 is provided in the water tank 1 and is covered outside the protective shell 11, and water outlets 121 are provided on all four sides of the bottom of the protective shell 11, and a plurality of U-shaped fixing plates 21 are provided at equal distances between the outer wall of the protective shell 11 and the inner wall of the processing shell 12, and a plurality of first water outlets 211 are provided on each of the fixing plates 21, a heat conducting layer 111 is provided on the protective shell 11 and between each adjacent two fixing plates 21, and a processing mechanism 2 is provided between the outer wall of the protective shell 11 and the inner wall of the processing shell 12 for performing scale treatment on the heat conducting layer 111 of the protective shell 11.

[0026] In this embodiment, the processing mechanism 2 includes a plurality of U-shaped movable plates 22, and the plurality of movable plates 22 are respectively arranged directly below a plurality of fixed plates 21. Each of the movable plates 22 is sealed and slidably connected to the outer wall of the protective shell 11 and the inner wall of the processing shell 12. A plurality of second water openings 221 are provided on the movable plates 22. A plurality of first springs 23 are connected to the bottom of each of the fixed plates 21, and the lower end of each of the first springs 23 is connected to the movable plate 22. A U-shaped scraper 24 is provided on the top and bottom surfaces of each movable plate 22 and on the side close to the protective shell 11. A control unit is provided on each movable plate 22 and at each second water opening 221 for controlling the opening and closing of the second water opening 221.

[0027] In this embodiment, the control unit includes a control box 25, which is mounted on the movable plate 22 and located on one side of the second water outlet 221. A piston plate 26 is sealed and slidably connected inside the control box 25, and a slide rod 27 is connected to the side of the piston plate 26 close to the second water outlet 221. The end of the slide rod 27 away from the piston plate 26 extends to the outside of the control box 25 and is connected to a baffle 28. The size of the baffle 28 is larger than the size of the second water outlet 221. The slide rod 27 is sealed and slidably connected to the control box 25. A second spring 271 is connected to the side of the piston plate 26 away from the slide rod 27. The other end of the second spring 271 is connected to the inner wall of the control box 25. A plurality of liquid flow holes 261 are provided on the piston plate 26, and the control box 25 is filled with hydraulic oil.

[0028] In this embodiment, an electromagnet 29 is provided at the bottom of each fixed plate 21 and at a corresponding position of the control box 25 on the movable plate 22. A pressure sensor 291 is provided on each fixed plate 21. The pressure sensor 291 is electrically connected to the control circuit of all the electromagnets 29 on the fixed plate 21. The piston plate 26 is made of ferromagnetic material. When the pressure sensor 291 is contacted and pressed, all the electromagnets 29 on the fixed plate 21 will be energized and magnetic.

[0029] In this embodiment, except for one liquid flow hole 261 on each piston plate 26, the remaining liquid flow holes 261 are all provided with a one-way valve 262, and the one-way valve 262 only allows liquid to flow from the side of the piston plate 26 close to the second spring 271 to the side of the piston plate 36 located on the slide rod 27.

[0030] In this embodiment, a water pump 3 is installed on the top of the water storage tank 1. The water inlet and outlet of the water pump 3 are respectively connected to a water pumping pipe 31 and a water supply pipe 32. The end of the water pumping pipe 31 away from the water pump 3 extends into the processing shell 12.

[0031] In this embodiment, the top of the water storage tank is provided with a water inlet 13, and the heat-conducting layer 111 is made of high-thermal-conductivity material, so as to quickly conduct the heat generated by the battery body 4 to the water in the water storage tank 1.

[0032] The working process and principle of the present application are as follows:

[0033] In use, the heat generated by the battery body 4 during charging and discharging is transmitted to the water in the water storage tank 1 through the heat-conducting layer 111 on the protective shell 11 and is absorbed by the water to reduce the temperature. When the battery body 4 is discharging, the unmanned aerial vehicle is also in a working state, and the water pump 3 will be started to work to draw the water between the protective shell 11 and the processing shell 12 through the water suction pipe 31. After the water at the top of the processing shell 12 is drawn away, all the moving plates 22 will slide up under the action of water pressure. When the moving plates 22 slide up to press the pressing sensors 291 on the fixed plates 21, all the electromagnets 29 will be energized to have magnetism to generate a magnetic attraction force on the piston plate 26 in the control box 25 to make the piston plate 26 slide to the side where the electromagnets 29 are located. Since the flow direction of the hydraulic oil in the control box 25 is the same as that of the one-way valve 262 at the flow liquid hole 261, all the flow liquid holes 261 are in a flow-through state, the flow of the hydraulic oil is large, and the piston plate 26 slides fast. When the piston plate 36 slides, the baffle 28 is pulled to move by the slide rod 27, and the second water inlet 221 is not covered. The water in the water storage tank 1 can be drawn away by the water suction pipe 31 through the water outlet 121, the second water inlet 221 and the first water inlet 211. At this time, the moving plate 22 loses the water pressure and slides down under the action of the first spring 23. After the moving plate 22 slides down, it no longer acts on the pressing sensor 291, the electromagnet 29 is de-energized, and the piston plate 26 will slide back under the action of the second spring 271. At this time, the flow direction of the hydraulic oil in the control box 25 is opposite to that of the one-way valve 262 at the flow liquid hole 261, only one flow liquid hole 261 without the one-way valve 262 flows the hydraulic oil, the flow is small, the speed of the piston plate 26 sliding back is slow, the second water inlet 221 will not be quickly covered, and the moving plate 22 can slide down to the original position. When the second water inlet 221 is completely covered, the moving plate 22 will be affected by the water pressure again to repeat the above steps to realize periodic up-and-down sliding. On the one hand, the water scale on the heat-conducting layer 11 can be scraped off by the scraper 24 driven by the moving plate 22 to slide up and down, so as to ensure the good heat exchange efficiency of the heat-conducting layer 111. On the other hand, the water between the protective shell 11 and the processing shell 12 is always in a flowing state, which can well cool the battery body 4, and the water after absorbing heat is drawn away and used up. Even if the water level in the water storage tank 1 is lowered below the height of the battery body 4, the protective shell 11 and the processing shell 12 are always in a water state and the water is at a low temperature, which can keep the battery body 4 at a good cooling effect.

[0034] It is apparent that the application can be carried out by other embodiments that do not depart from the spirit or essential characteristics thereof. Thus, the embodiments disclosed in this specification are to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the application are intended to be embraced therein.
