Anti-backflow waterpower automatic gate

Abstract

The invention relates to an anti-backflow waterpower automatic gate which belongs to the technical field of drainage system equipment and comprises a buffer pool and an underground storage tank disposed inside a flow way, wherein the underground storage tank is placed below the buffer pool, a gate is disposed between the buffer pool and the underground storage tank, the gate is fixed on one side of a spindle, and two ends of the spindle are respectively hinged to flow way walls on two sides of the flow way. The anti-backflow waterpower automatic gate also comprises a buoyant box room which is disposed inside the underground storage tank and realizes water inflow later than the underground storage tank, wherein a buoyancy box is fixed on the other side of the spindle, the buoyancy box is disposed inside the buoyancy box room, a buoyancy box room water outlet hole is disposed in the bottom of the buoyancy box room, the buoyancy box room water outlet hole is communicated with the underground storage tank, a plug sealing the buoyancy box room water outlet hole is disposed at the buoyancy box room water outlet hole, a floater is disposed inside the underground storage tank, and a linkage device is connected between the floater and the plug. The anti-backflow waterpower automatic gate provided by the invention prevents water in the underground storage tank from flowing back to the buffer pool.

Description

Technical field [0001] The invention belongs to the technical field of drainage system equipment, and specifically relates to an anti-backflow hydraulic automatic gate. Background technique [0002] In systems where municipal rainwater or sewage pipe networks overflow to natural water bodies (river, lake, etc.), gates are often used to control the water level. The gate needs to discharge flood according to different water levels. It needs to be driven by power, consumes more energy, and is inconvenient for maintenance. Moreover, the water level of the underground storage tank cannot be controlled. When the water level of the local lowered storage tank is too high, water will flow back into the buffer tank , Discharged into natural water bodies, thereby polluting the environment. Therefore, how to design a gate structure that is simple in structure, does not consume energy, and can control the water level of the underground storage tank is a current problem. Summary of the inven...
