Vehicle-mounted solar photovoltaic panel cleaning device

The utility model relates to the technical field of photovoltaic panel cleaning equipment, in particular to a vehicle-mounted solar photovoltaic panel cleaning device which comprises a carrier loader,a hydraulic mechanical arm, a hydraulic rotating mechanism, a hydraulic station, a diesel generating set, a centrifugal fan, a purging device, a hydraulic station and a diesel generating set. A hydraulic rotating mechanism is installed at the tail of the carrying vehicle hopper, a hydraulic mechanical arm is installed on the hydraulic rotating mechanism, and a purging device is installed at the outwards-extending end of the hydraulic mechanical arm. According to the utility model, the hydraulic slewing mechanism and the hydraulic mechanical arm are arranged, so that the purging device can beadjusted to a working posture which is relatively parallel to the solar photovoltaic panel, and air from the air outlet nozzle can be downward along the slope of the solar photovoltaic panel; in thisway, sand dust or floating
