Problems solved by technology

The oil pressure of the hydraulic cylinder of this structure decreases step by step during the lifting process, and the support for the dam slab is insufficient. Usually, the hydraulic cylinder is overloaded, which makes the hydraulic cylinder easy to fatigue and damage, and the single-point support is not reliable. Weak, poor safety performance, high accident rate

Embodiment Construction

[0019] The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

[0020] Hydraulic lifting dam of the present invention, as figure 1 As shown, the movable dam slab 1 is included, and the bottom end of the movable dam slab 1 is a movable hinge connection, which can rotate along the hinged shaft. On the backwater side of the movable dam 1, there is a hydraulic cylinder assembly supported by the movable dam 1 in the shape of a "herringbone", and the lifting control of the movable dam is realized through the expansion and contraction of the hydraulic cylinder. The hydraulic cylinder assembly is composed of multiple single-section hydraulic cylinders arranged in a row. The single-section hydraulic cylinder can ensure sufficient jacking oil pressure, strong jacking force, and quick response to lifting. The cylinder blocks 10 of the hydraulic cylinders are connecte...

Abstract

The invention discloses a hydraulic lifting dam which comprises a movable dam plate (1). The bottom of the movable dam plate (1) is in hinge connection, a hydraulic cylinder component in an inverted V-shaped support with the movable dam plate (1) is arranged on the backwater side of the movable dam plate (1) and comprises a plurality of single-section hydraulic cylinders which are in arrangement layout, cylinder bodies (10) of the hydraulic cylinders are mutually connected, the hydraulic cylinders are reversely arranged, a piston rod (20) arranged downwardly is connected with a lower support (4) in a hinged manner, and the piston rods (20) arranged upwardly are connected with upper supports (5) of the movable dam plate (1) in a hinged manner. The hydraulic lifting dam is firm and reliable in structure, sufficient in lifting strength, rapid in response, high in flood impact resistance and high in safety.

Description

technical field [0001] The invention belongs to the technical field of water conservancy, hydropower and urban river landscape engineering, and relates to a dam structure, more specifically to a hydraulic lift dam. Background technique [0002] In the construction of modern water conservancy and hydropower projects, dams have been widely used in response to the needs of urban water systems, landscape construction, environmental improvement, irrigation, and power generation in my country. At present, steel dams, rubber dams, and flap dams are the main products selected for engineering construction. However, rubber dams are difficult to manage, easy to damage and age, take a long time to raise the dam, have poor safety performance, and have a high accident rate; the manufacturing cost of steel dams High; the automatic flap dam has serious water blocking, which is not conducive to flood discharge, and floating objects can easily cause the dam to become unusable, so the safety p...
