Underwater hydraulic quick-closing gate capable of being opened and closed quickly

Abstract

The invention relates to an underwater hydraulic quick-opening and quick-closing gate which comprises a gate frame and a gate body, a fluid passing hole is formed in the gate frame, the gate body vertically slides along the gate frame to open or block the fluid passing hole, and the underwater hydraulic quick-opening and quick-closing gate further comprises a hydraulic cylinder and a hydraulic power unit used for driving the hydraulic cylinder. The hydraulic power unit is arranged in a drying area above the water surface, a gap between the gate frame and a wall body is filled with water-blocking sealing rubber strips after the gate frame is installed on the wall body, the gate frame and the gate body are each provided with a hydraulic cylinder support, and the two ends of a hydraulic cylinder are connected with the hydraulic cylinder supports on the gate frame and the gate body respectively. Frame guide rails used for guiding the gate body to slide are arranged on the two sides of the gate frame, and sealing strips shaped like a Chinese character'hui 'are arranged on the portions, around the fluid passing hole, of the frame guide rails. Compared with the prior art, the supporting thrust is large, opening and closing are rapid, and opening and closing are stable.

Description

technical field [0001] The invention relates to a drainage engineering gate, in particular to an underwater hydraulic quick-opening and closing quick-closing gate. Background technique [0002] As global warming causes climate change, there is a dramatic increase in extreme weather events. The demand for waterlogging and risk-removing equipment in drainage projects is also increasing. In the event of flood disaster, the key is to ensure the smoothness of the pipe network, and the fast and stable operation of the outlet equipment is particularly important. In order to meet the requirements of rapid drainage and risk elimination, the gate in the drainage project should have the following characteristics: fast opening and closing, strong sealing, easy operation and convenient maintenance. [0003] At present, the quick-closing gates produced at home and abroad generally use electric gates. The commonly used electric gates are mainly composed of electric hoists, driving screws...

AI Technical Summary

Problems solved by technology

The disadvantages of this structure are that in actual use cases, the size is small, the opening and closing speed is slow, and there are high-voltage cables under water, so there are certain safety hazards during operation; and the sealing of the equipment body cannot be guaranteed, and there are different degrees of leakage.
