An assembled movable dam that can play a role of mutual support

Abstract

The invention discloses an assembled movable dam capable of supporting each other, and relates to the technical field of movable dams. Above and corresponding to the positions of the first dam body unit and the second dam body unit, a first decompression unit and a second decompression unit are respectively fixed and installed, and the movable dam is respectively provided with a mutual support mechanism that supports each other and It acts as a decompression unit that shares the pressure on the electric hydraulic cylinder. The mutual support mechanism can make each movable dam have mutual support force. In actual use, it can make the entire movable dam-shaped interception structure withstand the water pressure capacity. It is stronger and will not affect the opening and closing of a single movable dam. The decompression unit can form a pulling force on the baffle of the dam body, thereby reducing the pressure on the electric hydraulic cylinder and prolonging the service life of the electric hydraulic cylinder when the water is stored and intercepted. .

Description

technical field [0001] The invention relates to the technical field of movable dams, in particular to an assembled movable dam capable of supporting each other. Background technique [0002] Active dam is a revolutionary achievement of water conservancy science and technology, and is currently the world's leading arc dam technology. It is widely used in agricultural irrigation, fishery, ship locks, sea tide blocking, small river management, construction of small hydropower stations, urban water systems and tourist landscapes. Engineering etc. Hydraulic dam is a new type of water retaining device, which has a significant effect on retaining water. [0003] The existing movable dams have the following deficiencies in actual use: [0004] 1. In actual use, the existing movable dams need to be subjected to strong water pressure and impact force when several movable dams jointly intercept the flow, which has higher requirements on the compressive performance of the existing mov...

[0005] 2. In the actual use of the existing movable dam, the water pressure acts on the dam body, and the dam body transmits the pressure to the electro-hydraulic cylinder. Compared with the dam body, the electro-hydraulic cylinder can bear less pressure and has a long Closure of time will easily lead to damage to the electro-hydraulic cylinder, resulting in the inability of the movable dam to open and affecting the flood discharge speed of the entire closure structure. pressure;
