Problems solved by technology

During the water blocking process of this kind of hydraulic dam, the hydraulic cylinder plays the role of supporting the dam body. As a power component, the hydraulic cylinder supports the dam body under high oil pressure all the year round, and the loss is serious; at the same time, the high-pressure oil in the hydraulic cylinder is affected by the external temperature change. Influenced by thermal expansion and cold contraction, the angle of the dam body is not fixed when blocking water

Abstract

The invention discloses a folding rod self-locking type hydraulic dam, and belongs to the field of hydraulic dams. The problems that an existing hydraulic dam is large in hydraulic cylinder supporting dam body loss, and sediment is likely to block a groove fixedly installed in the hydraulic cylinder are solved. The folding rod self-locking type hydraulic dam comprises a dam body, a folding rod, a hydraulic cylinder and a dam foundation. The bottom of the dam body is fixed to the dam foundation through a bearing pedestal and can be folded by winding a shaft. The folding rod is a foldable rigid rod, and the middle of the folding rod is hinged, wherein one end of the folding rod is movably connected to the dam body through a dam connecting base, and the other end of the hydraulic cylinder is movably connected to the back face of the dam body. The middle of the folding rod is hinged, one folding direction is fixed and cannot be folded in the fixed direction. A self-locking device is arranged on the folding rod. The folding rod can be locked and can be prevented from being folded in the other folding direction. The folding rod replaces the hydraulic cylinder for supporting, and no groove needs to be formed.

Description

technical field [0001] The invention belongs to the field of hydraulic dams, in particular to a folding rod self-locking hydraulic dam. Background technique [0002] Hydraulic dams are widely used in agricultural irrigation, fishery, ship locks, seawater tide blocking, urban river landscape projects and small hydropower stations. Traditional hydraulic dams use hydraulic cylinders to straighten the back of the movable dam surface with the bottom as the axis to achieve dam elevation. The purpose of blocking water, lowering dams and discharging floods. During the water blocking process of this kind of hydraulic dam, the hydraulic cylinder plays the role of supporting the dam body. As a power component, the hydraulic cylinder supports the dam body under high oil pressure all the year round, and the loss is serious; at the same time, the high-pressure oil in the hydraulic cylinder is affected by the external temperature change. Influenced by thermal expansion and cold contractio...
