[0028] The transmission mechanism 2 is composed of two groups of transmission units, which are respectively arranged on two groups of side frames 7. The transmission units include a driving transmission wheel 8, a driven transmission wheel 9, a conveyor belt 10 and an auxiliary transmission wheel 11. A driving shaft 12 and a driven shaft 13 are rotatably provided between the two groups of side frames 7. The driving transmission wheel 8 is sleeved on the driving shaft 12, the driven transmission wheel 9 is sleeved on the driven shaft 13, and the auxiliary transmission wheel 11 is rotatably provided on the side frame 7 through the wheel shaft.

[0031] When in use, the water outlets of the detergent supply device and the clean water supply device are connected to the water inlets of the two groups of pump bodies 22 respectively, and then the device can be used normally to clean the solar cells. When cleaning the solar cells, the solar cells are placed on the conveyor belt 10, and the two groups of side frames 7 can limit the solar cells from both sides to prevent the solar cells from shifting during the transmission process. Then the first motor 28 is started, and the solar cells are transported through the conveyor belt 10. When the solar cells pass through the first group of cleaning mechanisms 3, the detergent is first sprayed on the solar cells through the spray head 24. After the solar cells are transported to the cleaning mechanism 3, the first motor 28 is turned off, and the cylinder 26 is started.

The cleaning roller brush 15 rotates and moves at the same time, so that the solar cell can be scrubbed more comprehensively and thoroughly. After the scrubbing is completed, the cylinder 26 drives the U-shaped positioning frame 27 to move down, cancels the clamping limit of the U-shaped positioning frame 27 on the solar cell, and then starts the first motor 28 again to continue to convey the solar cell. When the solar cell passes through another group of spray mechanisms 4, the spray head 24 will spray clean water to rinse the solar cell. Through this device, the solar cell can be automatically cleaned, and the cleaning effect is better and the cleaning efficiency is higher.
