Washing device Shanghaidong motor driving unit 710 reversely rotates the washing device Shanghaidong motor 600 in response to a reverse rotation motor driving control signal, and the washing device Shanghaidongdong wheel 1300, 1400 reverse rotation while the washing device is below From (downward) to upward (upward), the first washed solar panel is washed second.

When the control device 400 that raised the cleaning device 100 in the upward direction senses the limit detection signal, it determines that the upward cleaning has been completed, and the control device 400 switches the washing device moving direction switching motor 500. Then, the washing device 100 is moved to the next provided solar panel. That is, the washing device 100 is moved to the left when viewed based on the automatic washing device, and the control device 400 outputs a driving control signal for moving left and right to the motor driving unit 710 for moving the washing device left and right to move the washing device left and right. The motor 600 is rotated.

Then, as mentioned above, the wheels 1500 for moving left and right for the washing apparatus rotate by the rotation of the motor 700 for moving left and right for the washing apparatus, and the auxiliary wheel of the horizontal guide rail 200 rotates in conjunction with this. .

The control device 400 moves the washing device 100 in the left-right direction and then moves it to the upper portion of the solar panel to be cleaned. This continues until a limit detection signal is input from the limit sensor 900.

When the limit detection signal is input, the control device 400 determines that the washing device 100 is seated in the next solar panel washing position, and outputs a forward rotation motor driving control signal to the motor driving unit 710 for vertical movement of the washing device. Let the top surface of the solar panel be cleaned. Subsequent descriptions will be omitted due to the relationship detailed above.
