The diameter of the opening end of the protruding part 32 is smaller than that of the closed end, so that the flow channel between the adjacent protruding parts 32 is of a trapezoid structure with a smaller bottom and a larger top, and when the water quantity is smaller, the lower part of the flow channel is correspondingly smaller, the flow speed is correspondingly increased, and impurities possibly existing in water are prevented from forming impurity precipitation due to too low flow speed, and part of holes are blocked.
The elevation of the bottom of the drainage ditch 5 is lower than the elevation of the top surface of the bottom plate 2. The purpose of this is that the water level in the drain is guaranteed to be lower than the closed bottom 321 of the bulge of the drain plate for the most of time, so that when the water level of the drain 5 rises, water accumulation is avoided in the space of the lower runner of the drain plate 3, and impurity precipitation is avoided.
