A steel dam gate with the function of removing sediment

Abstract

The invention relates to a steel dam gate having a silt clearing function and strong anti-pressure ability. The steel dam gate comprises a dam body, a base, a groove, a connecting block, a supportingblock, a hydraulic cylinder and a piston, wherein the groove is formed in the upper portion of the base; the bottom end of the dam body is hinged to the inner wall of the groove; the dam body is vertically arranged at one side in the groove; the supporting block is positioned at the other side in the groove; the supporting block is hinged to the inner wall of the groove; one end of the hydraulic cylinder is fixed to one side of the supporting block; the other end of the hydraulic cylinder sleeves one end of the piston; the other end of the piston is hinged to the connecting block; the connecting block is fixed to one side, close to the hydraulic cylinder, of the dam body; and a pressure relief mechanism and a silt clearing mechanism are arranged on the dam body. The steel dam gate having the silt clearing function and strong anti-pressure ability can realize reducing impact force on the dam body through the pressure relief mechanism, and avoids damage to the dam body; and the silt clearing mechanism prevents underwater silt from being accumulated to affect opening and closing of the steel dam gate.

Description

technical field [0001] The invention relates to the field of steel dam gate equipment, in particular to a steel dam gate with the function of removing sediment. Background technique [0002] The academic name of the steel dam is the bottom shaft driven flap gate. The steel dam gate is used to close and open the control facility of the discharge channel. It is an important part of the hydraulic structure and can be used to intercept water flow, control water level, adjust flow, and discharge sediment. and floaters etc. [0003] Existing steel dam gates still have some deficiencies in actual use. For example, after the water flow is intercepted, sand and sand in the water tend to accumulate at the bottom of the gate, and the accumulated sand will cause damage to the opening and closing of the gate. The resistance will affect the opening and closing of the gate. Not only that, but also undercurrent and vortex will be generated in the water. After the steel dam gate is subjecte...

Problems solved by technology

[0003] Existing steel dam gates still have some deficiencies in actual use. For example, after the water flow is intercepted, sand and sand in the water tend to accumulate at the bottom of the gate, and the accumulated sand will cause damage to the opening and closing of the gate. The resistance will affect the opening and closing of the gate. Not only that, but also undercurrent and vortex will be generated in the water. The steel dam gate will be deformed after being subjected to the impact force of water for a long time, which will affect the sealing performance, and in severe cases, the steel dam gate will be damaged.
