Hydraulic dam support rod unlocking device and use method

Abstract

The invention relates to a hydraulic dam support rod unlocking device and a use method. The hydraulic dam support rod unlocking device comprises a support rod, wherein the support rod is used for supporting a gate plate, a hinge is arranged on the upper end of the support rod, the support rod is fixed to the back of the gate plate by the hinge, support steps are arranged on a foundation of the lower end of the support rod, the lower end of the support rod is supported on the support steps, and the support rod and the gate plate are in a lambdoidal support state. The hydraulic dam support rod unlocking device is characterized in that a vertical rotating block is arranged on the front surface beside the support steps, the rotating block can rotate towards the support steps around a rotatingshaft under the action of external force, a reset device is arranged on the rotating block, the reset device is used for enabling the rotating block to return to the vertical state after the externalforce is eliminated, a groove or a pit is formed in the top surface of the rotating block, and the rotating circumferential surface of the groove or the pit exceeds the support steps when the rotatingblock rotates, so that the support rod cannot fall on the steps when the rotating block is pushed to rotate in the groove or the pit, and the support rod crosses the steps to be unlocked. The problemthat the support rod needs to be unlocked by external power is solved.

Description

technical field [0001] The invention relates to a dam structure of a water conservancy facility, in particular to a hydraulic dam support bar unlocking device and a using method. Background technique [0002] The hydraulic dam is a relatively simple movable dam. It is widely used in the construction of agricultural irrigation, fishery, ship locks, seawater tidal protection, urban river landscape engineering and small hydropower stations. The mechanical structure of the hydraulic lifting dam is scientific, not blocking water, not afraid of mud and sand deposition; not affected by floating objects; in the case of a very small loss of water, it can easily wash away the floating objects upstream, making the river clear; the dam is released quickly, Does not affect flood control safety; strong ability to resist flood impact. The structure of the hydraulic dam is usually composed of a gate plate, a gate plate lifting cylinder and a hydraulic pump station. It uses the gate plate...

AI Technical Summary

Problems solved by technology

However, when these structures are unsupported (unlocked), hydraulic cylinders are required to adjust the position of the support rods. The structures are too complicated, prone to failure, and the manufacturing and use costs are high, and the installation and construction are relatively difficult.
