Background technique

Present improving constantly along with rapid economy development and people's living standard, people to the demand of electricity in continuous increase, the power consumption that increases gradually in order to satisfy social progress, many countries constantly drop into huge fund and build on a large scale with thermoelectricity, rock gas, nuclear power is main big power station, this traditional power station is usually with coal, oil, gas is main generating raw material, their combustion gas bring very big pollution and destruction for the physical environment and the ecosystem, the human simultaneously coal that is had, oil, gas is extremely limited, along with yield increase year by year, the available energy is fewer and feweri, directly has influence on descendants's survival and development.

1/5 energy is from hydroelectric power in the world at present, and the water power plant utilizes the energy of the water of landing to drive turbo machine, sends a large amount of electric power thereby turbo machine then drives generator.But this traditional hydroelectric power system is normally built in some Water Energy such as reservoir, river course, lake big area of upstream and downstream drop of abundance and water relatively, and to environment requirements than higher, require to form the basin shape area of a large amount of water storages.Nonetheless, owing to be subjected to the restriction of physical features, the construction cost of hydroelectric power station is relatively more expensive comparatively speaking, builds very difficultly in the country of some poverty-stricken areas and some economics of underdevelopment, and universal face is very little.In some arids countries and regions short of rain, be subjected to the restriction of weather conditions and physical environment simultaneously, traditional hydroelectric system does not have the effect of any generating at all.With regard to the present available water system of China, major part belongs to the water system of small flow, low head, blocks the water water storage with rubber dam or lower artificial dam usually.Because the water drop is lower, the water energy can not drive turbine generation, causes the waste of water.

For this reason, it mainly is made up of pneumatics pump, impulse chamber, pressure chamber etc. to have the inventor once to design a kind of " supercharging potential energy pump ", after water with potential energy enters impulse chamber, close the impact valve, compressing the pneumatics pump simultaneously strengthens air pressure, and wash the valve block of pressing in the upright chamber open with water with impact force, air in the compression pressure chamber produces very big reaction force, water is sprayed from the mouth of a river of lifting of supercharging potential energy pump, this pump is a power with very little water drop potential energy, pumping lift is very high, can raise up to 15～30 meters usually, is not consume the valency energy, free of contamination suction pump.But at present big with this suction pump supporting water storing device complex structure, floor space, be not suitable for using.

Summary of the invention

The purpose of this utility model provides a kind of device that utilizes circulation water electricity generation, be power and make water can lift very high and effectively store and circulate with very little drop potential energy water by supercharging potential energy pump, and can provide power for driving turbine generation, the consumption of the valency energy is arranged with minimizing.For this reason, the utility model adopts the wet pit one end approach channel that communicates, the wet pit two ends are respectively equipped with intake gate and go out sluice, the upper end of wet pit is provided with the water tower pond in the lift of lifting the mouth of a river of supercharging potential energy pump, the supercharging water pipe water tower pond inner bottom part that communicates, the supercharging water pipe the other end turbo machine water intake that communicates, the turbo machine water outlet communicates in the dam, the wet pit lower end is provided with circulatory pool, circulatory pool one side is provided with circulatory pool and goes out sluice, the potential energy pump water inlet mouth of supercharging potential energy pump communicates in the wet pit lower end, the mouth of a river of lifting of supercharging potential energy pump communicates in the water tower pond, the drain opening of supercharging potential energy pump communicates in the circulatory pool upper end, with the supercharging potential energy pump that communicates in the circulatory pool lower end lift the water tower pond that communicates, the mouth of a river, its drain opening water channel that communicates out.The said structure design has realized the purpose of this utility model.

The utility model has the advantages that and to be power with very little drop potential energy water and to make water can lift very high and effectively store and circulate by supercharging potential energy pump, and can provide power for driving turbine generation, to reduce the consumption that the valency energy is arranged significantly, and it is rational in infrastructure, occupation area is little, and user cost is low.
