A hydraulic movable dam with strong impact resistance

Abstract

The invention discloses a hydraulic movable dam with strong impact resistance, and relates to the technical field of hydraulic movable dams. The impact force energy dissipation unit is respectively provided with a primary energy dissipation mechanism and a secondary energy dissipation mechanism. The primary energy dissipation mechanism passes through a simple The spring and telescopic rod structure initially offset the impact force generated when the wave impacts on the anti-pressure plate. The overall technical feature of the secondary energy dissipation mechanism is to convert the remaining impact force, that is, kinetic energy into potential energy, and because the entire There are several impact energy dissipation units, which are evenly distributed on the structure of the existing movable dam body, which is equivalent to the large area of ​​impact force generated by the impact of waves on the compression plate instead of the dam body. On the one hand, it can protect the entire dam structure, and on the other hand, it protects the entire electro-hydraulic cylinder to prevent the damage of the dam body and the electro-hydraulic rod due to long-term impact, and then the problem that it cannot be opened and closed normally, prolonging the service life of the hydraulic movable dam. service life.

Description

technical field [0001] The invention relates to the technical field of hydraulic movable dams, in particular to a hydraulic movable dam with strong impact resistance. Background technique [0002] The movable dam is a revolutionary achievement of water conservancy science and technology. It is currently the world's leading movable dam technology. It is widely used in agricultural irrigation, fishery, ship locks, seawater tidal protection, small river management, small hydropower station construction, urban water systems and tourism landscape projects. Wait. The movable dam is a new type of water storage device, which has a remarkable effect on water storage and overflow. [0003] During the water storage period of the movable dam, due to the large water storage area and the larger water surface, under the action of the wind, waves will be formed. The waves themselves carry impact and will directly hit the dam body of the movable dam. The impact will cause slight deformatio...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a hydraulic movable dam with strong impact resistance, which solves how the movable dam can automatically offset the impact force generated by the water body when it hits the dam body during water storage, thereby prolonging the entire The service life of movable dams
