Hinge movable dam

A hinge movable dam and movable dam technology, which is applied in water conservancy projects, sea area projects, coastline protection, etc., can solve the problem of being stuck between the dam surface that has been laid down and the dam surface that has not been put down, and the dam surface cannot rise and fall again. Smooth, unsynchronized rise and fall of several dam surfaces, etc., to achieve the effect of long service life, good flood drainage effect, simple and practical structure

Problems solved by technology

If there are slightly larger debris such as gravel in the upstream during flood discharge, it is easy to bend or damage the exposed support rods.
This will cause the dam surface to be unsmooth or not support at all when it rises and falls again.
And because the whole dam is made up of multiple dam surfaces, and the rise and fall of several dam surfaces are asynchronous, this may cause after a dam surface is put down, the floating objects in the upstream are concentrated on the put down dam surface and the dam surface. Between the dam surfaces that have not yet been put down, causing the adjacent dam surfaces to fail to collapse

Abstract

The invention discloses a hinge movable dam, which consists of a plurality of movable dam units, wherein the lower end of the water retaining dam face (1) of each movable dam unit is connected with a gate bottom tilting fillet (3) through a gate hinge (2). The hinge movable dam is characterized in that a hydraulic oil cylinder (5) is connected to the middle part of the inner side of each water retaining dam face (1); the hydraulic oil cylinders (5) are connected through synchronous motors (21); a support rod (7) is connected to the upper part of the inner side of each water retaining dam face (1); a chain (20) is connected to the lower end of each support rod (7), and is connected to a driving chain wheel (15) and a driven chain wheel (15'); each driving chain wheel (15) is connected with a driving shaft (16); each driven chain wheel (15') is connected with a driven shaft (16'); each driving chain wheel (16) is connected with a hydraulic motor (18). The hinge movable dam is simple and practical in structure, convenient to use, high in damage prevention capability, long in service life, safe and reliable, and has a good floodwater draining effect, water blocking is avoided, and good stress conditions are ensured.

Description

Technical field: [0001] The invention relates to a hinge movable dam, which belongs to the technical field of water conservancy barrages. Background technique: [0002] At present, the existing hinge movable dam is supported by other support rods in addition to the hydraulic rod support. When the dam surface is fully laid down for flood discharge, its support rods are exposed outside the dam surface, which has the disadvantage of being able to directly contact sundries. If there are gravel and other slightly larger debris in the upstream during flood discharge, it is easy to bend or damage the exposed support rods. This causes the dam surface to be unsmooth or simply unable to support when it rises and falls again. And because the whole dam is made up of multiple dam surfaces, and the rise and fall of several dam surfaces are asynchronous, this may cause after a dam surface is put down, the floating objects in the upstream are concentrated on the put down dam surface and ...
