Hydraulic movable dam

Abstract

The invention discloses a hydraulic movable dam, which comprises a rebar ground anchor piece, a hinged support, a movable plate, a hydraulic station, an oil pipe, a hydraulic cylinder and two support rods, wherein the rebar ground anchor piece is deeply buried in the foundation of the dam; the part, which extends out of the ground, of the rebar ground anchor piece is provided with the hinged support; the hinged support is a loop-type hinged support; the hinged support is provided with a concentric shaft; the concentric shaft penetrates through the hinged support and is movably connected with the hinged support; the movable plate is provided with two hydraulic rods and the two support rods; the hydraulic rods and the support rods are in articulated juncture with the movable plate; the hydraulic rods and the support rods are controlled by the hydraulic cylinder; the hydraulic cylinder is connected with the hydraulic station through the oil pipe; the hydraulic station is used for controlling the direction, the pressure and the flow of oil flow. The movable dam disclosed by the invention is simple in structure and convenient in operation, and can swing within a range of 0-180 degrees, and thus, single-sided and two-sided water stopping of the movable dam can be conveniently realized; the concentric shaft is fixedly arranged on the loop-type hinged support, so that the concentric shaft and a base are prevented from being changed in position, and the water leakage of the bottom part of the movable dam is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of hydraulic dam design, in particular to a hydraulic movable dam. Background technique [0002] The movable dam is a revolutionary achievement of water conservancy science and technology. It is currently the world's leading arc 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 tourist landscapes. engineering etc. [0003] The hydraulic dam is a new type of water storage device, which has a significant effect on water storage. The overall cost of the hydraulic dam is only lower than that of the sluice and rubber dams of the same specification. During the wet season, nothing can be seen on the riverbed, which neither affects flood control nor navigation. Therefore, there is no need to build ship locks. But after the movable plate of the hydraulic dam was put dow...

AI Technical Summary

Problems solved by technology

However, after the movable slab of the hydraulic dam is lowered, the movable slab is higher than the top of the fixed embankment, and the dam surface cannot be parallel to the river bed.

Moreover, the movable plate of the hydraulic dam is hinged to the base. During the lifting process of the movable plate, the position of the movable plate and the base will change, which will easily cause water leakage at the bottom of the hydraulic dam, making the reliability and safety of the hydraulic dam lower.
