Photovoltaic cleaning robot for photovoltaic panel

The utility model discloses a photovoltaic cleaning robot of a photovoltaic panel, which comprises a cross beam, a rolling brush assembly and a rolling wheel capable of rolling along the upper edge of the photovoltaic panel, the rolling brush assembly is arranged on the cross beam, and the rolling wheel is arranged on the cross beam through a movable assembly used for changing the position of the rolling wheel relative to the cross beam. According to the photovoltaic cleaning robot for the photovoltaic panels, the movable assembly capable of adjusting the positions of the idler wheels in a sliding mode is designed, when the photovoltaic cleaning robot corresponds to the photovoltaic panels of different sizes, only the positions of the idler wheels need to be adjusted in a sliding mode, and then photovoltaic panel splicing seams and rolling brush splicing seams can be aligned; therefore, one photovoltaic cleaning robot can be suitable for cleaning photovoltaic panels of various models, generalization of the ph
