[0035] A plurality of nozzles 9 are sealed and plugged into one side of the water tank 2. The nozzles 9 are located on one side of the cleaning brush 4. An air pump 10 is fixed to the top outer wall of the outer shell 1 by bolts. A pressurized pipe 11 is sealed and plugged into the air outlet end of the air pump 10. The other end of the pressurized pipe 11 is connected to the water tank 2. Under the action of the air pump 10, gas is input from the pressurized pipe 11 into the water tank 2, thereby increasing the pressure in the water tank 2. Under the action of the pressure, the water in the water tank 2 is sprayed from the nozzles 9 onto the photovoltaic panel 23.

[0036] The top outer wall of the housing 1 is fixed with a mounting box 12 by bolts. Two guide ropes 18 are provided between the two sides of the mounting box 12. A plurality of guide wheels 13 and two drive wheels 14 are rotatably connected between the top inner wall and the bottom inner wall of the mounting box 12. The guide ropes 18 pass between the drive wheels 14 and the two guide wheels 13. Two drive motors 15 are fixed with bolts to the top outer wall of the mounting box 12. The output end of the drive motor 15 is fixedly connected to the top of the drive wheel 14.

Then, the processor controls the drive motor 15 to start, and the drive wheel 14 rotates under the drive motor 15. Therefore, under the auxiliary transmission action of the guide wheel 13, the installation box 12 moves along the guide rope 18, thereby driving the device to move on the photovoltaic panel 23.

[0041] During the movement, first, the processor controls the motor 6 and the air pump 10. Under the action of the air pump 10, the gas is input from the pressurized pipe 11 into the water tank 2, thereby increasing the pressure in the water tank 2. Under the action of the pressure, the water in the water tank 2 is sprayed from the nozzle 9 onto the photovoltaic panel 23. At the same time, driven by the motor 6 and the transmission action of the toothed belt 8, the rotating shaft is driven to rotate, so that the cleaning brush 4 brushes on the photovoltaic panel 23, and then brushes the photovoltaic panel 23. Then, the water-absorbing roller 5 is driven to rotate under the transmission action of the toothed belt 8, so that the water-absorbing roller 5 rolls on the photovoltaic panel 23, and then absorbs the water on the photovoltaic panel 23.
