The supercharging propeller can increase the downstream flowing speed of rainwater from the water outlet, and the water turbine can drive the transmission disc to rotate, so that the first connecting rod and the second connecting rod synchronously move left and right and drive the grid plate to move left and right.
As a further optimization, the driving assembly comprises a connecting shaft which is vertically arranged and connected with an output shaft of the water turbine, horizontally arranged and penetrates out of the vertical section and is connected with the output shaft in a transmission manner, and an input shaft which is vertically arranged and is connected with the connecting shaft in a transmission manner, and the transmission disc is coaxially arranged on the input shaft.

Specifically, when the rainwater is accumulated in the environment where the drainage system is located due to the fact that rainwater is increased and the like, the pressurizing propeller can start to work, water flow from the rainwater grate flows downwards at a larger flow speed and pressure, and the flowing speed of the water flow in the drainage pipeline is greatly improved, so that the drainage efficiency of the whole drainage system is improved.
