The second mounting plate 301 is stuck at one end of the mounting frame 1. Two second rollers 402 are fixed to one side of the second mounting plate 301 by bolts. The second rollers 402 roll at one end of the mounting frame 1, so as to facilitate the movement of the device. A collection box 6 and an air suction pump 7 are fixed to the top of the first mounting plate 3 by bolts. A drawer is slidably inserted into one end of the collection box 6. The air outlet end of the air suction pump 7 is hermetically inserted with an air inlet pipe 8. The other end of the air inlet pipe 8 is communicated with the collection box 6. A first shunt pipe 9 is fixed to the bottom of the first mounting plate 3. A plurality of dust suction heads 10 are hermetically inserted into the bottom of the first shunt pipe 9. Under the suction of the air suction pump 7, the dust on the photovoltaic panel 2 is sucked into the first shunt pipe 9 from the dust suction heads 10. Then, the dust is input into the drawer of the collection box 6 through the air inlet pipe 8 for collection;

[0028] An installation opening is provided at the top of the first mounting plate 3. An installation frame 16 is fixed in the installation opening by bolts. A third mounting plate 18 is slidably connected in the installation frame 16. A sponge block 19 is bonded to the bottom of the third mounting plate 18. An installation cover 17 is fixed to the top of the installation frame 16 by bolts. Two telescopic rods 20 and two springs 21 are welded to the bottom of the installation cover 17. The springs 21 are sleeved on the outside of the telescopic rods 20. The bottom ends of the springs 21 and the telescopic rods 20 are fixedly connected to the top of the third mounting plate 18. Under the elastic action of the springs 21, the telescopic rods 20 are stretched, so that the third mounting plate 18 moves downward in the installation frame 16, and then the sponge block 19 is closely attached to the photovoltaic panel 2. A handle 5 is fixed to the top of the first mounting plate 3 by bolts. Pulling the handle 5 makes the first rollers 4 and the second rollers 402 roll on the mounting frame 1, thereby driving the device to move, and then the sponge block 19 rubs on the photovoltaic panel 2, so as to scrub the photovoltaic panel 2. The outer wall of the handle 5 is provided with anti-slip grooves;

[0029] The top of the mounting cover 17 is fixed with a liquid storage box 22 by bolts. A plurality of liquid storage cavities 2201 are provided in the liquid storage box 22.

[0031] A U-shaped sliding rod 14 is slidably connected to the bottom of the first mounting plate 3. A brush 15 is adhered to the inner wall of the bottom of the U-shaped sliding rod 14. The brush 15 contacts the sponge block 19. Pulling the U-shaped sliding rod 14 drives the brush 15 to move, so that the brush 15 rubs against the bottom of the sponge block 19, thereby cleaning the sponge block 19 for the next use. The output end of the photovoltaic panel 2 is electrically connected to a photovoltaic controller. The model of the photovoltaic controller is JR3220. The output end of the photovoltaic controller is electrically connected to a storage battery. A plurality of liquid adding tubes 2301 are welded to the top of the sealing cover 23. The top ends of the liquid adding tubes 2301 are threadedly connected with dust-proof covers. Unscrew the dust-proof covers to inject water into the liquid storage cavities 2201 through the liquid adding tubes 2301 for storage.

[0032] The working principle of this embodiment: When in use, unscrew the dust-proof cover and inject water into the liquid storage cavity 2201 through the liquid adding tube 2301 for storage. Then, cover the dust-proof cover. When removing dust, first, start the suction pump 7. Under the suction of the suction pump 7, the dust on the photovoltaic panel 2 is sucked from the dust suction head 10 into the first shunt tube 9. Then, the dust is input into the drawer of the collection box 6 through the air inlet pipe 8 for collection;

[0033] Next, under the elastic action of the spring 21, the telescopic rod 20 is stretched, so that the third mounting plate 18 moves downward in the mounting frame 16, and then the sponge block 19 is closely attached to the photovoltaic panel 2. Then, the water in the liquid storage cavity 2201 flows into the diversion pipe 24 and is absorbed by the sponge column 25. Next, the water is transferred from the sponge column 25 to the sponge block 19. Then, the handle 5 is pulled to make the first roller 4 and the second roller 402 roll on the mounting frame 1, thereby driving the device to move, and then the sponge block 19 rubs on the photovoltaic panel 2, so as to scrub the photovoltaic panel 2.

[0034] Then, the air inlet pump 11 is started. Under the suction of the air inlet pump 11, the gas is sucked into the second shunt pipe 12 and then sprayed onto the photovoltaic panel 2 from the air outlet nozzle 13, so as to dry the photovoltaic panel 2 and avoid water stains left on the photovoltaic panel 2. After dust removal, the U-shaped slide rod 14 is pulled to drive the brush 15 to move, so that the brush 15 rubs against the bottom of the sponge block 19, so as to clean the sponge block 19 for the next use.

[0035] All the electrical components mentioned in this article are electrically connected to the external main controller and 220V mains, and the main controller can be a conventional known device such as a computer that plays a control role.
