Watercourse sluice gate with stratified water intake function and operation method thereof

Abstract

The invention provides a watercourse sluice gate with a stratified water intake function thereof. The sluice gate comprises a plurality layers of platforms which form a step-like structure and are arranged in the water flowing direction. The platforms below the topmost platform are all of hollow structures. The top of each hollow structure is covered with turning plates. The turning plates are rotatably connected with the corresponding platforms. Each hollow structure is internally provided with water buckets with top openings. A piston is arranged in the middle of each water bucket. The top of each piston is provided with a push head used for pushing to the corresponding turning plate to rotate. The two sides of the bottom of each water bucket are connected with a water inlet pipe and a water outlet pipe correspondingly. Liquid level control valves are arranged in the water inlet pipes and the water outlet pipes. The bottoms of the water buckets of the bottommost platform are furtherprovided with underground pipes. Water inlets of the underground pipes communicate with water inlets of the water inlet pipes and are internally provided with electric valves. The turning plates can rotate up and down through the liquid level control valves according to the water level, and stratified water intake and surface water intake can be realized through internal water passing or top waterpassing of the watercourse sluice gate.

Description

technical field [0001] The invention relates to the field of water conservancy engineering equipment, in particular to a novel gate structure for water conservancy engineering, that is, a river gate with layered water intake function and its working method. Background technique [0002] The construction of the water conservancy project has a significant impact on the environment of the reservoir area and the downstream river course. The formation of the reservoir turned the original natural river with fast flow velocity and uniform water temperature into a relatively static large-scale water body. Affected by solar radiation, convective mixing and heat transfer, the vertical water temperature of the water body in the reservoir area appeared a climatic distribution, and the water temperature of the bottom water body was relatively low. The natural water temperature is low. The traditional single-layer water intake method will cause the temperature of the water discharged fro...

AI Technical Summary

Problems solved by technology

The traditional single-layer water intake method will cause the temperature of the water discharged from the reservoir to be lower than the natural water temperature of the river in summer and higher than the natural water temperature of the river in winter. The low temperature water discharged from the reservoir will have a significant adverse effect on the reproduction and growth of aquatic organisms in the downstream river.

[0003] At present, in some agricultural irrigation projects, it is strictly required to take warm surface water for agricultural irrigation to increase crop yields, but ordinary gates cannot fulfill this functional requirement
