The accumulated water of the grid plate flows into the water receiving groove 21 to increase the overall weight of the water receiving groove 21, and in the case that the water receiving groove 21 continues to increase in weight, the water receiving groove 21 gradually moves downward against the elastic force of the driving elastic member 23, so that the connecting rod 11 no longer moves downward under the upward pushing force of the water receiving groove 21. After the water receiving groove 21 moves downward, the drainage mechanism 3 drains the accumulated water in the water receiving groove 21, and the water receiving groove 21 moves upward under the pushing of the driving elastic member 23 to drive the cleaning rod 1 to move upward.

[0034] The lower end of the water receiving groove 21 is penetrated by a water outlet 211 in communication with the inner cavity of the water receiving groove 21, and the accumulated water in the water receiving groove 21 is drained through the water outlet 211.
