Larger impurities can be filtered through the filter plate 9 to reduce the problem of larger impurities entering the interior of the L-shaped plate 8 and affecting the normal flow of water.

[0024] The blocking mechanism 11 includes a curb body 111, a limiting column 112 and a card plate 113. The bottom of the curb body 111 is in contact with the top of the cushion layer 1 and the top of the L-shaped plate 8. There are several limiting columns 112, and the limiting columns 112 are evenly fixedly connected to the bottom of the curb body 111.
