Water conservancy channel gate

Abstract

The invention provides a water conservancy navigation channel gate. The water conservancy navigation channel gate comprises two gates, wherein the two gates are respectively constructed on a high-water level side and a low-water level side; each gate comprises a base which is constructed at the bottom of a river, two frame columns are constructed upwards on the base, and a door plate which can move up and down along the frame columns is arranged between the two frame columns; plungers which are fixed to the door plate are symmetrically arranged on both sides of the door plate, the plungers are inserted into vertical tubular hydraulic cylinders which extend downwards from above the frame columns, and the bottoms of the hydraulic cylinders extend below the base; a high-water level communicating pipe which is communicated with water on the high-water level side and a low-water level communicating pipe which is communicated with water on the low-water level side are respectively led from the bottom of each hydraulic cylinder; two electromagnetic valves are respectively connected with the high-water level communicating pipe and the low-water level communicating pipe in series. The water conservancy navigation channel gate has the advantage of low energy consumption.

Description

technical field [0001] The invention relates to the field of water conservancy engineering, in particular to a water conservancy ship channel gate. Background technique [0002] In many hydrological environments, the two sides of the river gate usually have different water levels, and in many cases, the water level difference on both sides of the gate is relatively large; such as various hydropower stations, and various inner and outer rivers in cities; considering ships Generally, the gate needs to design a channel, and the design of the channel needs to ensure that the water level on both sides of the channel remains stable after the ship passes through; When the ship sails from the low water level side to the high water level side, first keep the high water level side gate closed, and open the low water level side gate, so that the water level between the two gates is equal to the water level on the low water level side, and wait until the ship enters the two gates After...

AI Technical Summary

Problems solved by technology

In this regard, when ships enter and exit frequently in the shipway gate, it is necessary to open and close the two gates frequently, and the driving source usually uses a motor, so the energy consumption is relatively large
