The second gear 712 rotates, the second gear 712 drives the first gear 710 to rotate, the first gear 710 drives the rotating cylinder 706 to rotate, and the rotating cylinder 706 drives the support member 707 to rotate, so that the upper and lower two absorbent cotton cloths 709 are turned over, avoiding one absorbent cotton cloth 709 Too much moisture affects the wiping effect, then start the drive motor 703, the output end of the drive motor 703 drives the two-way threaded screw rod 701 to rotate, and the two-way threaded screw rod 701 drives the two moving blocks 702 to approach or move away from each other, and the two moving blocks 702 squeezes the water-absorbent cotton cloth 709 during the moving process so that the water contained in it is squeezed out and falls into the collection tank 713, and the water is guided to the outside of the photovoltaic panel by the collection tank 713, and the delivery pipe 16 will be filtered The air filtered by the net 608 is sent into the transmission cylinder 13, and is sprayed to the surface of the photovoltaic panel through the cooperation of the air supply pipe 18 and the air outlet bucket 17, so as to increase the air velocity near it and further increase its drying speed. Rotation occurs over time, the transmission blade 15 drives the transmission shaft 14 to rotate, and the transmission shaft 14 drives the rubber column 12 to rotate, and the rubber column 12 can be pressed against the outer frame of the photovoltaic panel so that the sewage remaining between the bottom of the outer frame and the photovoltaic panel is removed, thereby The dust cleaning device on the photovoltaic panel has a better cleaning effect.
