Problems solved by technology

[0003] At present, the hinge movable dam usually uses a hydraulic cylinder as the power structure to drive the dam body to lift, and when the dam body needs to maintain a specified height to achieve water retention, the hydraulic cylinder must always maintain a state of resisting water loads, that is: the The hydraulic cylinder needs to maintain the working state of supporting the dam body at all times, but due to the instability of the drive of the hydraulic cylinder, if only the hydraulic cylinder is used to support the dam body, it is easy to cause the hydraulic cylinder to lose pressure and leak water, making the dam body unable to maintain accurate water retention Or the height of water storage. In addition, because the hydraulic cylinder is always in the working state of supporting the dam body, the hydraulic cylinder is prone to excessive fatigue and damage, which shortens the service life of the hydraulic cylinder

Abstract

The invention relates to the technical field of water conservancy projects, in particular to a hinge movable dam. The hinge movable dam comprises a dam body, a power structure, a self-locking structure and a supporting structure. The power structure is connected with the dam body, and the power structure drives the dam body to rotate. The self-locking structure comprises a drive part and a limiting part, the drive part is connected with the limiting part and drives the limiting part to rotate, and the limiting part is provided with a limiting groove. The supporting structure comprises a supporting part and a sliding part connected with the supporting part, the supporting part is rotationally connected with the dam body, and the sliding part slides into the limiting groove or slides out ofthe limiting groove when the supporting part and the dam body relatively rotate. According to the hinge movable dam, the dam body can be kept at an appointed height all the time, and the service lifeof the power structure can also be prolonged.

Description

Technical field [0001] This application relates to the technical field of water conservancy engineering, in particular to a hinged movable dam. Background technique [0002] In recent years, due to the flexibility of the water level adjustment of the hinged movable dam, the hinged movable dam has been widely used in water conservancy projects to achieve functions such as flood control, water supply, and hydroelectric power generation. [0003] At present, hinged movable dams usually use hydraulic cylinders as the power structure to drive the dam body to move up and down, and when the dam body needs to maintain a specified height to achieve water retention, the hydraulic cylinder must always maintain a state of resisting water load, namely: The hydraulic cylinder needs to always maintain the working condition of supporting the dam. However, due to the instability of the drive of the hydraulic cylinder, if the dam is only supported by the hydraulic cylinder, the hydraulic cylinder is...
