[0031] Embodiment 1:

[0032] As Figures 1-5 shown, the present invention. Specifically, a drone with an automatic cleaning function for a photovoltaic panel includes a drone 300 for cleaning the photovoltaic panel 400. A cleaning component 200 that can move along the surface of the photovoltaic panel 400 is provided on the photovoltaic panel 400. The drone 300 can be connected to the cleaning component 200 to drive the cleaning component 200 to move; the drone 300 includes a drone frame 301, propellers connected to the drone frame 301, and landing gears connected to the bottom of the drone frame 301. A liquid storage tank 303 is connected to the bottom of the drone frame 301.

[0033] In this embodiment, the cleaning component 200 includes end plates 201 located at both ends of the surface of the photovoltaic panel 400. The two end plates 201 are connected by a connecting rod 202. A limiting column 205 is also provided at the bottom of the end plate 201.

[0034] In this embodiment, the cleaning component 200 further includes a rotary brush 204. The rotary brush 204 is sleeved on the outer periphery of the connecting rod 202 located in the middle. A water outlet pipe 203 and a wiping cotton 206 are respectively arranged on the left and right sides of the rotary brush 204. Both the water outlet pipe 203 and the wiping cotton 206 can contact the surface of the photovoltaic panel 400.

[0035] In this embodiment, a plurality of water outlet holes are formed in the water outlet pipe 203 along its length direction on the side close to the photovoltaic panel 400. One end of the water outlet pipe 203 is communicated with a first connecting pipe 209, and the first connecting pipe 209 is exposed outside the end plate 201.

[0036] In this embodiment, rollers 207 are arranged on the inner side of the end plate 201, and positioning columns 208 are arranged on the outer side of the end plate 201.

[0037] In this embodiment, the landing gear of the drone 300 includes two landing gear main rods 302 connected to the drone frame 301 and a landing gear bottom rod 3021 horizontally connected to the bottom of the landing gear main rods 302. The landing gear main rods 302 are inclined. A connecting head 3022 is arranged at the end of the landing gear bottom rod 3021. A positioning hole column 3024 adapted to the positioning column 208 is formed inside the connecting head 3022 on one of the landing gear bottom rods 3021. A second connecting pipe 3023 is arranged inside the connecting head 3022 on the other landing gear bottom rod 3021. The first connecting pipe 209 can extend into the inside of the second connecting pipe 3023 to realize the connection between the second connecting pipe 3023 and the first connecting pipe 209.

[0038] In this embodiment, the liquid storage tank 303 is communicated with the second connecting pipe 3023 through an infusion pipe 304, and a control valve 305 for controlling the flow of the infusion pipe 304 is installed on the liquid storage tank 303.

[0039] In this embodiment, an image acquisition module 306 for acquiring images of the photovoltaic panel 400 is also carried on the drone 300.

[0040] When using the drone of the present invention for cleaning photovoltaic panels, first, place the cleaning assembly 200 on the surface of the photovoltaic panel 400, and make the limit posts 205 cooperate with the edge of the photovoltaic panel 400 or the mounting bracket to ensure that the cleaning assembly 200 is stably placed on the photovoltaic panel 400. At this time, the rollers 207 are in contact with the surface of the photovoltaic panel 400, facilitating the subsequent movement of the cleaning assembly 200. Then, control the drone 300 to fly towards the cleaning assembly 200. When approaching the cleaning assembly 200, it can be achieved based on the image acquisition module 306 through the visual assistance system carried on the drone 300, so that the positioning hole column 3024 on the end connector 3022 of the bottom rod 3021 of the landing gear accurately aligns with the positioning post 208 outside the end plate 201, and at the same time aligns the second connecting pipe 3023 with the first connecting pipe 209. Then, insert the positioning post 208 into the positioning hole column 3024, and insert the first connecting pipe 209 into the second connecting pipe 3023 to complete the connection between the drone 300 and the cleaning assembly 200. After the connection is completed, open the control valve 305 on the liquid storage tank 303, and the cleaning liquid in the liquid storage tank 303 enters the water outlet pipe 203 through the infusion pipe 304, the second connecting pipe 3023 and the first connecting pipe 209, and is evenly sprayed on the surface of the photovoltaic panel 400 from the water outlet holes on the water outlet pipe 203. At the same time, start the propeller of the drone 300 to drive the cleaning assembly 200 to move on the surface of the photovoltaic panel 400. During the movement, the rotary brush 204 rotates to brush the wet surface of the photovoltaic panel 400 to remove dirt. The wiping cotton 206 is behind the rotary brush 204 to wipe the surface of the photovoltaic panel 400 after brushing to dry the remaining water stains. During the cleaning process, the image acquisition module 306 continuously acquires the image information of the photovoltaic panel 400 and transmits the image data to the control system (not shown in the figure) of the drone 300. The control system analyzes the images to judge the pollution degree and pollution area of the photovoltaic panel 400. If it is found that a certain area is severely polluted, the control system can adjust the flight speed and direction of the drone 300 to make the cleaning assembly 200 stay in this area for a longer time for key cleaning, and at the same time can appropriately increase the water supply in this area to improve the cleaning effect.

[0041] After the cleaning is completed, close the control valve 305 to stop the water supply. Control the drone 300 to fly laterally to pull out the positioning post 208 from the positioning hole column 3024 and draw out the first connecting pipe 209 from the second connecting pipe 3023 to separate the drone 300 from the cleaning assembly 200. Then, fly the drone 300 back to the designated location, and the cleaning assembly 200 remains on the photovoltaic panel 400 waiting for the next cleaning task.
