Furthermore, during the movement of the mounting frame (2), the rotating wheel (11.43) is driven to rotate by the friction force. The rotation of the rotating wheel (11.43) drives the fan blade (11.42) to rotate through the rotating shaft (11.44), so that the air outside the cleaning box (11.2) is transported from the air pipe (11.41) to the cleaning box (11.2) and passes through the filter (11. 46) to purify the air, while the air in the cleaning box (11.2) is discharged from the air holes (11.3) and acts on the photovoltaic panel (1) and the bristles (11.12). When the photovoltaic panel (1) is completely moved to the side of the cleaning brush (11.1) away from the cleaning box (11.2), the movement stops, and the mounting frame (2) still abuts against the rotating wheel (11.43), and the mounting frame (2) is supported by the rotating wheel (11.43); The order of step 1, step 2 and step 3 is the same, and they can be switched freely according to annular factors such as light intensity, weather conditions, wind speed, wind direction, etc.
