Inclined axis hydraulic automatic control gate

Abstract

The invention relates to an oblique-shaft type hydraulic self-control gate comprising gate piers, a gate floor plate, a gate plate, a waterstop, an oblique shaft and arc hydraulic damping devices. The gate piers are symmetrically and vertically disposed on two sides of the gate floor plate, and the oblique shaft is disposed on the gate pier on one side and is in rigid connection with the gate pier through an anchoring structure; the lower end of the oblique shaft is fixed at the joint of the gate pier on the side and the gate floor plate, and the upper end of the oblique shaft faces the upstream direction of water flow, and the oblique shaft is mounted obliquely with a 45-degree angle formed between the oblique shaft and the bottom edge of the gate pier of the side; the gate is fixed on the oblique shaft, and the arc hydraulic damping devices are arranged between the gate and one gate pier. By the oblique-shaft type hydraulic self-control gate, opening and closing of the gate can be controlled automatically according to the upstream water level, automatic control of the gate through upstream coming water is realized, a working system of unattended operation is realized, and popularization and application in practice are facilitated.

Description

[0001] 1. Field

[0002] The invention relates to an inclined-axis hydraulic automatic control gate. 2. Background technology

[0003] The hydraulic automatic flap gate is a kind of hydraulic gate, which is an energy-saving and environment-friendly gate developed by Chinese hydraulic engineering technicians after more than 40 years of hard work and has completely independent intellectual property rights. Since the birth of the first generation of hydraulic self-controlled flap gates in the early 1960s, it has experienced four development stages: horizontal axis double hinge type, multi-branch hinge type, roller linkage type and slider type hydraulic automatic control type.

[0004] The main structure of the hydraulic automatic flap gate is reinforced concrete, which can generally be used to replace flat lift gates, arc gates and rubber dams, and is suitable for river water storage and flood discharge. Because the hydraulic automatic flap gate has a relatively simple structure...
