The accompanying drawing 1 of the description shows the top view of the local buried pump gate station. The local buried pump gate station takes the working well 100 as the main frame, and its two ends are respectively connected with the water inlet 110 and the water outlet 120. In order to reduce the resistance encountered when the water flows through, the water inlet 110 and the water outlet 120 are arranged at opposite side. Moreover, in order to reduce solid debris from entering the working well 100 with the water flow, a trash grid 600 is provided at the water inlet 110 .

When the hydraulic rod 300 expands and contracts, it can drive the gate 200 to turn over; moreover, the hydraulic rod 300 also serves as a lock. When the gate 200 blocks the water flow, the hydraulic rod 300 continuously exerts pressure on the gate 200 to resist the impact of the water flow.

A water pump 400 is installed on the gate 200 , and the upstream area 130 and the downstream area 140 can communicate with each other through the water pump 400 after the gate 200 is closed. When the water level in the downstream area 140 is higher than the water level in the upstream area 130, and it is necessary to continue to drain urban rainwater to the open sea, the water pump 400 can be turned on after closing the gate 200 to force the water in the upstream area 130 to be exported to the downstream area 140.
