Hinge dam

Abstract

The invention discloses a hinge dam. The hinge dam comprise an arched dam body and first bases; the arched dam body is connected with the first bases through driving mechanisms; each driving mechanismcomprises a hydraulic press; telescopic rods are mounted at the upper ends of the hydraulic presses correspondingly; the telescopic rods are connected with the arched dam body through connecting rodsand connected with the hydraulic presses through connecting frames; second bases are mounted in the first bases; first tracks are disposed on one sides of the second bases; second tracks are disposedon the inner walls of the second bases; the second tracks are connected with base plates through protruding blocks; mounting cavities are formed in the base plates; a plurality of power generating mechanisms are mounted on the upstream surface of the arched dam body; and each power generating mechanism comprises a first cavity, wherein the middle of the first cavity is connected with an impellerthrough a rotary shaft, and a net is mounted in an opening of the first cavity. By means of the hinge dam, the water flow impact resistance can be effectively enhanced, the risks of deformation or collapse of the hinge dam are lowered, usage is convenient, fast and efficient, the safety is high, and the practicability is good.

Description

technical field [0001] The invention relates to the technical field of waterproof engineering equipment, in particular to a hinge dam. Background technique [0002] Sluice gates are required when intercepting river water storage or drainage. Sluice gates can be divided into flap dams, hydraulic dams, hinge dams and other dam bodies. The hinge dam is a dam body panel and foundation that can be lifted and lowered under the action of a hydraulic rod, similar to a door. Shaft hinge. [0003] For example, a hinge dam disclosed in the Chinese invention patent No. 201610095221.0 includes a dam surface, a bottom support, a hydraulic cylinder, and a supporting member. The dam surface is hinged to the bottom support, and the hydraulic cylinder includes a cylinder and a piston rod. The cylinder is hinged with the bottom support, one end of the piston rod extends into the cylinder, and the other end of the piston rod is hinged with the back of the dam surface. The supporting member inc...

Problems solved by technology

[0004] Although the use of this hinge dam reduces the load on the hydraulic system after the dam surface is raised, thereby reducing the risk of hydraulic system collapse, it cannot adjust the separation and closure of the hinge dam according to the river water level, and it cannot effectively use water energy to carry out Power generation, inconvenient to use, low efficiency
