Hydraulic control system and hinge dam assembly

Abstract

This application relates to a hydraulic control system and a hinge dam assembly. The hydraulic control system includes a first branch, and the first branch includes a diverter synchronous valve. The diverter synchronous valve includes a chamber, a rotating shaft arranged in the chamber, and a plurality of rotors arranged on the rotating shaft. The rotors are distributed at intervals along the axial direction of the rotating shaft. , each rotor rotates synchronously with the rotating shaft, the diverter synchronous valve has a first opening and a plurality of second openings for medium circulation and communication with the chamber, each second opening communicates with each hydraulic cylinder one by one, each rotor communicates with each second opening One-to-one corresponding setting, when each rotor transports the medium from the first opening to each second opening, each hydraulic cylinder generates a first stroke, and in the first stroke, each hydraulic cylinder drives each hinge dam to rise synchronously; When each rotor transports the medium from each second opening to the first opening, each hydraulic cylinder generates a second stroke, and in the second stroke, each hydraulic cylinder drives each of the hinge dams to descend synchronously.

Description

technical field [0001] The present application relates to the technical field of movable dams, in particular to a hydraulic control system and a hinge dam assembly. Background technique [0002] Hinge dam is a new type of movable sluice. It is mainly composed of dam surface, hydraulic rod, hydraulic cylinder and hydraulic pump station. The dam surface is connected with the foundation connecting plate fixed on the foundation of the river bank. The way is to use the hydraulic cylinder to straighten the back of the dam surface with the bottom as the axis of the movable water-retaining dam, so as to realize the purpose of raising the dam to stop the water and lowering the dam to discharge the flood. [0003] Multiple hinge dams can be set in the river channel. When all the hinge dams are raised, the flow in the river channel is the largest. When only a few hinge dams are raised, the flow control in the river channel can be realized. So as to achieve the purpose of throttling. ...

AI Technical Summary

Problems solved by technology

[0004] There are often a lot of floating objects on the water surface in the river. When the single leaf hinge dam is raised, the floating objects are easily stuck between the two hinge dams, which will cause unsafe factors for the operation of the hinge dam.

At the same time, since the shape of the cross-section of the river channel is trapezoidal and the flow velocity of the water is relatively large, the impact force produced by the water in the river channel on each hinge dam is also different, which makes the loads borne by each hydraulic cylinder different.
