Hydraulic movable dam with high impact resistance

Abstract

The invention discloses a hydraulic movable dam with high impact resistance, and relates to the technical field of hydraulic movable dams. A first-stage energy dissipation mechanism and a second-stageenergy dissipation mechanism are arranged in an impact force energy dissipation unit, the first-stage energy dissipation mechanism performs primary offsetting on impact force which is generated during wave impacting and acts on a pressure-resistant plate through a simple spring and a telescopic rod structure, the second-stage energy dissipation mechanism is integrally and technically characterized in that remaining impact force, namely kinetic energy, is converted into potential energy, due to the fact that multiple whole impact force energy dissipation units are arranged and evenly distributed on an existing movable dam body structure, impact force generated during wave impacting acts on the pressure-resistant plate in a large area instead of a dam body, so that on one hand, the whole dam body structure can be protected, on the other hand, a whole electric hydraulic cylinder is protected, the problem that the dam body and an electric hydraulic rod are damaged due to long-term impactand the dam body cannot be normally opened and closed is solved, and the service life of the hydraulic movable dam is prolonged.

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...
