A water conservancy water retaining gate power generation device

Abstract

The invention relates to a water retaining gate electric generation device in water conservancy projects. The water retaining gate electric generation device comprises a first gate, a second gate, a third gate, an impeller device, an electric generator set, a wastewater treatment device and a floating object collecting device. By improving the impeller device and the electric generator set, rotating potential energy can be provided for the electric generator set when the gates are laid down and raised, accordingly, the wastewater treatment device and the floating object collecting device can be energized, no extra electric energy needs to be provided, energy consumption is reduced, and paving of external lines is reduced. By arranging the floating object collecting device, floating objectsfloating on one sides of the gates in a centralized mode can be collected, and the phenomenon that the floating objects flow to the down stream through rotational flow or flow to and fro for a long time to impact the gates, and loss caused to the fatigue strength of gates is avoided.

Description

technical field [0001] The invention belongs to the fields of water conservancy engineering and new energy power generation, and in particular relates to a power generation device for a water conservancy water retaining gate. Background technique [0002] In today's increasingly serious environmental pollution in China, the development of new energy is becoming more and more important. Both water conservancy and wind power generation use the flow of water or wind to transmit kinetic energy to the rotating blades, and the energy is transmitted to the generator set through the rotation of the rotating blades, thereby generating electrical energy. [0003] In many large and small water conservancy projects in China, the water retaining gate is a kind of component that must be installed. Through the opening and closing of the water retaining gate, the operation of water storage and flood discharge is realized. The current retaining gate is only this kind Because the water retai...

Problems solved by technology

[0003] In many large and small water conservancy projects in China, the water retaining gate is a kind of component that must be installed. Through the opening and closing of the water retaining gate, the operation of water storage and flood discharge is realized. The current retaining gate is only this kind Because the water retaining gate bears high pressure on one side all the year round, it is easy to cause deformation of the water retaining gate and affect the side seal, resulting in water leakage

And when the sluice gate is raised (especially sometimes when a small amount of water needs to be released, half of the sluice gate needs to be raised), the shear stress of the lower flowing water on the lower end of the sluice gate is very concentrated, which easily causes the lower side of the sluice gate to the bend

[0004] Due to the eddy effect of water, a lot of floating objects will be concentrated on the side of the water retaining gate all the year round. The floating objects not only pollute the water quality and affect the landscape, but also repeatedly impact the water retaining gate with the impact of the water flow, reducing the water retaining gate fatigue strength

The existing method is manual fishing, but this operation not only consumes a lot of manpower, but also causes production accidents
