Novel gate system for water conservancy and hydropower

Abstract

The invention discloses a novel gate system for water conservancy and hydropower. The system comprises a gate mounting seat, a speed reducing motor, a driving rotating shaft, a first gear, a second gear, a third gear, a first rack, a movable gate plate, a second rotating shaft, a fourth gear, a second rack, a guide mechanism and a driving mechanism, wherein the second rack is connected with the adjacent first rack and the second rack through a horizontal sliding mechanism. The system has the beneficial effects that the second rack and the fourth gear are controlled by the driving mechanism tobe engaged or disengaged, so that the opening number of movable gates is changed, the flow of the gates is adjusted, and the height of the water level is roughly controlled; and the movable gates canbe opened or closed only through rotation, lifting is not needed, the space, occupied by a lifting device, of a dam crest is reduced, and passing of people and vehicles on the dam crest is facilitated.

Description

technical field [0001] The invention relates to the technical field of gates, in particular to a novel gate system for water conservancy and hydropower. Background technique [0002] The gate is used to close and open the control facility of the discharge (discharge) channel. An important part of a hydraulic structure, which can be used to intercept water flow, control water level, adjust flow, discharge sediment and floating objects, etc. When selecting the gate form, it needs to be based on the working nature of the gate, the setting position, the operating condition, the span of the gate hole, the opening Closing force and project cost, etc., combined with the characteristics of the gate, referring to the existing practical experience in operation, are determined through technical and economic comparison. [0003] The existing planar gate is an integral structure, and the motor drives the screw or the sling to lift the gate. Although the structure is simple, the water fl...

AI Technical Summary

Problems solved by technology

[0003] The existing planar gate is an integral structure, and the motor drives the screw or the sling to lift the gate. Although the structure is simple, the water flows out from the bottom of the raised gate. The adjustment of the water level requires the staff to observe at all times, and then when it is about to reach the control Lower the gate when the water level is high; and the lifting device of the gate is high, occupying the space on the top of the dam and hindering the passage of people and vehicles on the top of the dam
