Anti-silt rotating water blocking gate

Abstract

The invention discloses an anti-silt rotating water blocking gate in the technical field of water conservancy facilities. Gate walls on the two sides of a riverway are included; a bottom plate is arranged at the bottom of the riverway; an opening and closing machine is arranged on at least one side of the riveryway; a gate body used for intercepting water is arranged in the riverway; rotating armsare arranged at the two ends of the gate body, and are rotationally supported on the gate wall through a rotating shaft; a piston rod stretching end of the opening and closing machine is hinged to the rotating arms; the bottom plate comprises a high position face and a low position face between which an arc-shaped face is arranged; the arc-shaped face is matched with the gate body; and the lowestend of the arc-shaped face is not lower than the plane where the low position face is located. In use, sediment, stone, trees and the like in upstream incoming flow can directly pass through the gatebody to be discharged to the downstream, and cannot be accumulated at the arc-shaped face position on the bottom plate, and therefore it can be avoided that the gate is clamped and blocked. The anti-silt rotating water blocking gate has the technical effects of being reliable to use and capable of performing silt removing automatically.

Description

technical field [0001] The invention relates to a gate device, in particular to a rotary water-retaining gate device. Background technique [0002] A two-way flip arc gate is disclosed in the Chinese patent database, its application number: CN201320472037.5; application date: 2013-08-02; publication number: CN203420260U; publication date: 2014-02-05, its structure includes civil engineering Structure, curved gate body, support mechanism, hydraulic cylinder and bottom sill, the civil structure is arranged on the left and right sides of the curved The arc-shaped gate body is fixedly connected and hinged to the civil structure, the hydraulic cylinder is horizontally fixed on the civil structure, and its piston rod is hinged to the support mechanism. The gate body in this device can be flipped down and opened under the drive of the hydraulic cylinder. After opening, the arc-shaped gate body is located below the water surface, without any equipment or structures above the water ...

AI Technical Summary

Problems solved by technology

Its shortcoming is that: the bottom sill of the device is provided with an arc-shaped groove matching with the gate body, and the groove is at the bottom of the river, which is easy to cause sediment deposition, resulting in the gate switch being blocked, and even directly causing the gate to be deformed and damaged
