The fixing rod 143 moves toward the direction of the protective plate 7 and contacts the inclined surface of the trapezoidal block 144. The fixing rod 143 squeezes the trapezoidal block 144 to move upward. The upward movement of the trapezoidal block 144 drives the hollow rod 145 to move upward. The upward movement of the hollow rod 145 causes the water in the collection box 141 to flow out through the water inlet hole 147, so that the cleaning brush can be cleaned. 133 intermittently flows out rainwater when cleaning the protective plate 7 to prevent the cleaning brush 133 from directly scraping the protective plate 7, which may cause scratches on the protective plate 7 and affect the service life of the protective plate 7. At the same time, the cleaning brush 133 can be cleaned more thoroughly with water, thereby improving the cleaning effect. At the same time, when the linear motor 131 moves downward, it will drive the fixed rod 143 to move downward. The downward movement of the fixed rod 143 will drive the contact with the trapezoidal block 144 to be separated, so that the trapezoidal block 144 is reset by the reset spring. The reset of the trapezoidal block 144 will drive the hollow rod 145 to move downward. The downward movement of the hollow rod 145 will drive the sealing plate 146 to move downward. The sealing plate 146 is used to seal to prevent rainwater from leaking and affecting the subsequent cleaning effect.
