Arc-shaped terrace beam sluice gate with layered water intake function and working method thereof

Abstract

The invention relates to an arc-shaped terrace beam sluice gate with a layered water intake function and a working method thereof. The sluice gate comprises the arc-shaped terrace beam sluice gate, anarc-shaped sluice gate slot, a fixed pulley, a hydraulic hoist, a rotating shaft, a hoist rod and an electric motor; the arc-shaped terrace beam sluice gate comprises a first arc-shaped sub sluice gate, a second arc-shaped sub sluice gate and a third arc-shaped sub sluice gate; and the third arc-shaped sub sluice gate is provided with a third cavity which can accommodate the insertion of the second arc-shaped sub sluice gate, the second arc-shaped sub sluice gate is provided with a second cavity which can accommodate the insertion of the first arc-shaped sub sluice gate, the first arc-shapedsub sluice gate is inserted into the second cavity of the second arc-shaped sub sluice gate, and the second arc-shaped sub sluice gate is inserted into the third cavity of the third arc-shaped sub sluice gate. According to the arc-shaped terrace beam sluice gate with the layered water intake function, the overall movement of the terrace beam sluice gate is controlled through the hydraulic hoist, lifting of the first arc-shaped sub sluice gate is controlled through the electric motor, and layered water intake and surface water intake of the arc-shaped terrace beam sluice gate are realized. Thehydraulic hoist is used for controlling whole movement of the terrace beam sluice gate to the height of flood scouring and silting, and a function of flood scouring and silting of the terrace beam sluice gate is realized.

Description

technical field [0001] The invention relates to an arc stacked beam gate with layered water intake function and a working method thereof, belonging to the field of hydraulic engineering equipment. Background technique [0002] The investigation of the data of the built water conservancy and hydropower projects shows that the deep reservoir and high dam with multi-year regulation performance have obvious vertical stratification of reservoir water temperature, the surface water temperature is high, the deep water temperature is low, and some mineral indicators in the deep water exceed the standard, which has a certain stench , Deep water intake cannot provide high-quality water sources, and it is difficult to guarantee the quality of water supply. [0003] The main functions of the reservoir are water supply and irrigation, and the gravity flow pressurized pipeline is used for water delivery. The low temperature and low turbidity water in the lower part of the reservoir is not...

Problems solved by technology

[0002] The investigation of the data of the built water conservancy and hydropower projects shows that the deep reservoir and high dam with multi-year regulation performance have obvious vertical stratification of reservoir water temperature, the surface water temperature is high, the deep water temperature is low, and some mineral indicators in the deep water exceed the standard, which has a certain stench , deep water intake cannot provide high-quality water sources, and it is difficult to guarantee the quality of water supply

[0003] The main function of the reservoir is water supply and irrigation. The gravity flow pressure pipeline is used for water delivery. The low temperature and low turbidity water in the lower part of the reservoir is not conducive to the treatment of the water plant and is not conducive to the growth of crops.
