The visual monitoring module 11 is used to monitor the position of the heating plate on the upper side of the photovoltaic panel and to determine whether there is an ice layer on the upper side of the photovoltaic panel; the angle sensor 10 detects the angle relationship between the heating plate and the photovoltaic panel, and transmits the data to the controller. If the heating plate is not parallel to the photovoltaic panel, the controller issues instructions to control the first position adjustment component, the second position adjustment component 6, the first angle adjustment component 7 and the second angle adjustment component 9 to make corresponding adjustments according to the data of the angle sensor 10, until the heating plate is parallel to the photovoltaic panel and the cleaning component 8 is facing the position to be cleaned.

The visual monitoring module 11 is used to monitor the position of the heating plate on the upper side of the photovoltaic panel and determine whether there is an ice layer on the upper side of the photovoltaic panel; the angle sensor 10 detects the angle relationship between the heating plate and the photovoltaic panel, and transmits the data to the controller. If the heating plate is not parallel to the photovoltaic panel, the controller issues instructions to control the first position adjustment component, the second position adjustment component 6, the first angle adjustment component 7 and the second angle adjustment component 9 to make corresponding adjustments according to the data of the angle sensor 10, until the heating plate is parallel to the photovoltaic panel and the cleaning component 8 is facing the position to be cleaned. If there is an ice layer on the surface of the photovoltaic panel, start the electric heating plate 801 to heat and melt the ice. After the ice melting is completed, the second motor 808 is started to drive the cross-shaped transmission rod 807 to rotate, driving the rotating block 806, the bevel gear ring 805 and the bevel gear 8031 ​​to rotate, so that the cleaning roller brush 803 starts to rotate to clean the surface of the photovoltaic panel; at the same time, the fourth motor 8092 is started to drive the screw 8091 to rotate, so that the cleaning roller brush 803 moves back and forth during the rotation process to achieve cleaning of a larger area. After cleaning, the electric heating plate 801 dries the remaining water stains on the photovoltaic panel.

[0049] Step 4: After the cleaning work is completed, the output shaft of the fourth motor 8092 is controlled to rotate to drive the screw 8091 to rotate, so that the cleaning roller brushes 803 are squeezed against each other, and then the cleaning roller brushes 803 are controlled to rotate to squeeze out the water in the cleaning roller brushes 803 to achieve self-cleaning of the cleaning roller brushes 803.
