Problems solved by technology

But at the same time, it also brings some new problems: the quality of deep water is deteriorating, and the accumulation of sediment is high, which has a great impact on the quality of water supply; the temperature of deep water has adverse effects on ecological living environment problems such as downstream irrigation and ecological water replenishment.
Layered water intake with gate holes on each floor has a complex structure, and there are many buildings, large land occupation, and large investment; the traditional stacked beam layered water intake structure relies on hoists and automatic hanging beams to take out the gates one by one to achieve stratification. The effect of water intake can only be taken from the upper layer of water, and the control of layered water intake is not flexible

Abstract

The invention relates to a device for controlling water feeding, particularly to a gate structure of taking water from different layers or taking water together by a plurality of layers, and specifically to a layered water intake gate. The device comprises a stop log gate arranged at a water intake, wherein the complete gate is placed in a gate groove; the gate groove is fixed on a concrete dam base, and is characterized in that the stop log gate comprises a plurality of gate sections, wherein a telescopic rod is arranged between every two gate sections for connection; each telescopic rod is connected with a main beam of each gate section; a power output device for driving the telescopic rod to move is arranged on each telescopic rod. The device has flexile operation, simple structure, and small investment, is beneficial to popularization and application, and has active using effect.

Description

technical field [0001] The invention relates to a water supply control device, in particular to a gate structure for layered water intake or multi-layer common water intake used at water intakes in water conservancy and hydropower projects, in particular to a layered water intake gate. Background technique [0002] With the rapid development of water conservancy and hydropower, various domestic reservoirs are mostly used for water supply, irrigation, power generation, flood control and other purposes, which have played a huge role in promoting regional economy and improving people's lives. But at the same time, it also brings some new problems: the quality of deep water is deteriorating, and the accumulation of sediment is high, which has a great impact on the quality of water supply; the temperature of deep water has adverse effects on ecological living environment problems such as downstream irrigation and ecological water replenishment. [0003] For example, in order to s...
