Steel hydraulic river sluice

Abstract

The invention discloses a steel hydraulic river sluice which comprises a control system and a plurality of sluice gate units. Each sluice gate unit comprises a secondary concrete sluice gate groove, amain anchor bolt embedded part, a sluice gate body, a sensor, an oil cylinder, a swing oil cylinder, a hydraulic system and a limiting switch. All the sluice gate bodies harmoniously move on the whole. According to the river sluice, rising and falling of the multiple sluice gate units are automatically controlled; during outage caused by flooding, hydraulic oil can be pressed back to an oil tankthrough the self-weight of water, and the water level is controlled to achieve safe flood discharge; through the combined-type design, the installation process is simplified, no middle sluice pier isneeded, and maintenance is easy, convenient and feasible; the arc-shaped sluice gate bodies and a stiffened plate can effectively smoothen a water flow; the sluice is supported through the oil cylinders and the swing oil cylinders, and a foundation is simple; no mechanical bearing is needed, no guiding groove is needed so that a water seal cannot be blocked by sand entering of the guiding groove,and no space is occupied by a hydraulic arm; and information collected by the sensors is transmitted to the control system, and the control system sends an instruction to the hydraulic systems to automatically control the oil cylinders to adjust the elevation angles, namely the water retaining heights, of the sluice gate bodies.

Description

technical field [0001] The invention relates to a water conservancy gate, in particular to a steel hydraulic barrage. Background technique [0002] The barrage dam is a water retaining device that intercepts the water flow of a river channel to raise the water level or regulate the flow. It can raise water level, form reservoir, regulate runoff, concentrate water head, and be used for flood control, water supply, irrigation, hydroelectric power generation, improve navigation, form landscape, etc. Generally speaking, a traditional barrage is composed of a barrage and a gate. The barrage is used for water storage, and the closing and opening of the gate is used to control water storage or release. [0003] The integration of barrage and gate into one is a brand-new barrage mode that has become more popular in recent years. It omits the barrage structure of the dam and replaces it with a gate to block the river and adjust the water level, which greatly simplifies the overall ...
