The invention discloses a detecting and cleaning device of a robot integrated with electrified detection and cleaning, which comprises a vertical installing frame, a cross installing frame, a driving device, a cleaning power device and a cleaning brush; a grab groove with a downward opening is arranged on the cross installing frame, and the cleaning power device is installed on an entity around the grab groove on the cross installing frame; the cross installing frame is connected to the vertical installing frame, and the driving device can make the cross installing frame to lift along the vertical installing frame; the cleaning brush is installed on an output part of the cleaning power device. Through the movement of the cleaning power device, the cleaning brush is driven to remove dust on the inner wall of an insulator. Meanwhile, the cross installing frame can stably lift along with the vertical installing frame, so that the cross installing frame can keep away from the insulator when the robot is translated. The detecting and cleaning device has the advantages of simple structure, stable movement, high cleaning efficiency and good effect.
