Pumped storage power station

Abstract

The invention belongs to the technical field of generating sets, in particular to a pumped storage power station. The pumped storage power station adopts the structure that two power transmission floating body water tanks are communicated with each other through two or more water flow passages; power transmission floating bodies are arranged in both the power transmission floating body water tanks; liquid ballast chambers are arranged in the power transmission floating bodies, and are communicated with one another through water feed / drainage pipelines; an on-off valve is arranged on each water flow passage; water is fed into and drained from the power transmission floating body water tanks through a feed pump and a drainage pump; two power transmission floating bodies are connected with one end of a corresponding lever; the other ends of the levers are connected with a connecting rod; one end of the connecting rod is connected with a generator through a booster engine, or two ends of the connecting rod are connected with generators through booster engines respectively; water level variation in the power transmission floating body water tanks drives the levers to swing around a fulcrum, so as to drive the connecting rod to work and further drive the generator(s) to generate power. The pumped storage power station has the advantages that the efficiency is high; the operation is simple; the application is wide in range and free from limitation of districts; the operation is safe and reliable.

Description

Technical field: [0001] The invention belongs to the technical field of power generation devices, in particular to a pumped storage power station. Background technique: [0002] Electric energy refers to the ability of electricity to do work (that is, generate energy) in various forms. Electric energy is widely used in various fields such as power, lighting, metallurgy, chemistry, textiles, communication, broadcasting, etc. It is the main driving force for the development of science and technology and the leap of the national economy. At the same time, electric energy also brings great convenience to people's life. In daily life, electricity is also inseparable. Electricity is currently the most scarce. At present, thermal power generation is still used more. Thermal power generation generally refers to the general term for the method of using the heat generated by the combustion of fuels such as oil, coal, and natural gas to heat water, turning the water into high-tempe...

AI Technical Summary

Problems solved by technology

[0004] First, the dam needs to be built, the location is remote, the project volume is large, the power grid needs to be erected, and the cost is high;

[0005] Second, the site selection has limitations and occupies a large area, and the surrounding area of ​​the dam must have a solid foundation;

[0006] Third, the drop between the upper and lower reservoirs should be large;

[0007] Fourth, pumping water from the lower reservoir to the upper reservoir has high lift, high power consumption, low efficiency, and a long cycle from pumping water to generating electricity;

[0008] Fifth, it is easily affected by floods, droughts, etc., and has a certain impact on the natural environment;

[0009] Sixth, during the entire operation process, part of the energy will be lost during conversion, which will not increase the power generation, and can only use the price difference of electric energy to realize profits
