Cleaning beam auxiliary driving assembly and photovoltaic cleaning robot

The invention provides a cleaning beam auxiliary driving assembly and a photovoltaic cleaning robot. The cleaning beam auxiliary driving assembly comprises a cleaning beam stretching across the photovoltaic panel array and an auxiliary driving mechanism arranged between the two ends of the cleaning beam, the cleaning beam comprises an upper beam section and a lower beam section which are arranged in a segmented mode, the upper beam section and the lower beam section are connected through a movable part, and the auxiliary driving mechanism is arranged between the upper beam section and the lower beam section. The movable part allows the butt joint ends of the upper section beam and the lower section beam to relatively rotate in the direction perpendicular to the photovoltaic panel array so as to generate an included angle; the auxiliary driving mechanism comprises auxiliary wheels, the auxiliary wheels are arranged at the butt joint ends of the upper section beam and the lower section beam, and the auxiliary w
