At the same time, the collection tank 91 can also collect rainwater, and the water inside the collection tank 91 is filtered through the filter plate 94. The filtered water flows into the water tank 88 through the water pipe 98, realizing water recycling and saving water resources. When the scraper rod 82 continues to move and contacts the third L-shaped rod 92 and squeezes the third L-shaped rod 92, the third L-shaped rod 92 The third L-shaped rod 92 moves away from the solar panel 6 under the extrusion force, contacts the hammer rod 95 and squeezes the hammer rod 95, and the hammer rod 95 moves towards the filter plate 94 under the extrusion force. The movement of the hammer rod 95 drives the filter plate 94 to move, and the movement of the filter plate 94 drives the second spring piece 96 to move. The second spring piece 96 moves and contacts the second arc block 97 and generates vibration to prevent the filter plate 94 from being blocked, affecting the water circulation and reducing the working efficiency of the water circulation.
