When moving to one side of the signal light, the water in the water tank is first pumped out by controlling the water pump, and then the water is sprayed to the signal light through the sprinkler head. , then the U-shaped support mounting plate continues to move, and the second telescopic device drives the movable support mounting frame forward, so that the cleaning roller contacts the signal light sprayed with water. At the same time, the third rotating motor is controlled to work, driving the cleaning roller to rotate to clean the signal light. Then the third telescopic device drives the bellows forward, so that the air outlet of the bellows is close to the cleaned signal light. At the same time, the fan is controlled to start working, and air flow is blown out through the bellows outlet box to the cleaned signal light, and the water stains remaining on its surface are blown away. After the signal light is cleaned, the above steps are reversed to make the cleaning assembly separate from the support mounting assembly, contact and cooperate with the lifting support assembly, and finally descend back to one side of the bottom end of the support vertical plate.
