An energy-dissipating buffer hydraulic dam

Abstract

The invention relates to an energy dissipation buffer type hydraulic dam which comprises a dam body. A first mounting base is arranged on the dam body and is connected with a connecting baffle througha first hinge shaft, a second mounting base is arranged on the right side face of the baffle and is connected with a top head of a piston rod of a first multistage hydraulic cylinder through a secondhinge shaft, the tail end of the multistage hydraulic cylinder is connected with a third mounting base through a third hinge shaft, and the third mounting base is fixedly connected to a top head of apiston rod of a second multistage hydraulic cylinder, and the second multistage hydraulic cylinder is horizontally arranged in a foundation pit on the dam; a plurality of drainage holes are formed in the upper portion of the baffle, guide sliding rails are arranged on the two sides of the drainage holes, a sliding plate in sliding connection with the guide sliding rails are arranged between theguide sliding rails, and a displacement adjusting device is arranged above the sliding plate; and a buffer energy dissipation device is connected to the left side of the baffle through a connecting device. According to the energy dissipation buffer type hydraulic dam, the buffer energy dissipation device is additionally arranged in front of the baffle; meanwhile, the anti-rusting treatment on thebaffle is strengthened, the service life of the overall hydraulic dam is prolonged, the practicability is high, and the dam is worthy of popularization.

Description

technical field [0001] The invention belongs to the technical field of hydraulic dams, and in particular relates to an energy-dissipating and buffering hydraulic dam. Background technique [0002] The hydraulic dam is a dam with many advantages. It uses a row of hydraulic cylinders to withstand the rotatable dam surface to achieve the purpose of water retention and flood control. However, the current hydraulic dam has some disadvantages: [0003] a. The hydraulic force directly acts on the dam body, and long-term direct impact can easily cause damage to the hydraulic support rod; [0004] b. Since the dam body and hydraulic support rods are soaked in water for a long time, they are prone to rust and are easily damaged; [0005] c. The flow can only be discharged by adjusting the overall height of the dam body, and the discharge method is single; [0006] d. The upstream water level cannot be adjusted automatically; [0007] e. Vulnerable components lead to low overall ser...
