Description
Technical field
The present invention relates to a kind of astable, low current hydraulic power generation system, this power generation system can directly absorb the kinetic energy of current and be converted into electric energy, without building dam, needn't damming to great rivers, can at rivers and utilizing ocean current each section along the line, build power station neatly.
Background technique
China soil is vast, river distributes extensively, current through line is long, along sea, southeast seashore, has ocean current, containing very huge energy, and the energy that we can utilize at present seldom.Take the Changjiang river makes a simple computation as example: get flow velocity V=2m/s, hundred million tons of flow m=900 are (by 3000 kilometers long, flow 30000m
3/ s calculates), generated output is 1.8 hundred million Mw, the utilization ratio by 1%, its theoretical generated output is 18 hundred million Kw, and its actual generator installation total amount is only 1,820 ten thousand Kw.Also having in addition a lot of tributaries also to contain has huge energy.If can develop, be just equivalent to increase by tens up to a hundred pipe of reinforced concrete at Three Gorges Power Stations.China has not just needed to build nuclear power station and thermal power station.
Because current hydro-electric power generating equipment generally adopts water turbine, lean on higher head that larger water flow impact pressure is provided, need to build dam and dam.Like this, first possibility influence ecological environment, secondly affects navigation, affects human lives.Build dam simultaneously and dam that to need upstream and downstream physical features to reach a certain height poor, can not arbitrarily build.
Also have a kind of waterwheel of traffic cycle formula to generate electricity for river waterflow, but can only be in the surface operation in river, and institute takes up space greatlyr, should not build on a large scale power station.
Consistent with the power taking mode of similar " water flow power ship and power station thereof " (patent No. 200710120011.3) patent of invention of patent of the present invention, but because this invention is provided with guide rail, not only affect current and also increased resistance, on the one hand that peculiar to vessel to make buoyancy aid resistance relatively large in addition, the resistance of series connection waterpower plate is larger, if build power large-scale electric generating station, just can not use Anchor Cable, Security is unreliable.
Make water can be converted into mechanical energy with patent of the present invention similar " river waterflow and utilizing ocean current power generation system " (patent No. 201120196017.0), then by mechanical energy, be converted into electric energy.But this kind of mode, because the flow velocity of water is unstable, can not guarantee that the electricity sending is constant, thereby can not meet national grid usage requirement.
Utilize compressed air and water flow to form gas pressure energy with patent of the present invention similar " utilizing the method for compressed air and water flow generating " (publication number CN1063145), pressurized gas are that directly ejection promotion gas-turbine rotates and drives generator operation to send electric energy.Also has the method and the equipment thereof that relate to a kind of wind-power electricity generation with similar " a kind of method of wind-power electricity generation and power generation system thereof " (the publication number CN101482099) of patent of the present invention.The method of this kind of wind-power electricity generation, is first stored into air compressing in air holding vessel, then with the high-pressure air in air holding vessel, promotes gas-turbine, and gas-turbine drives generator to realize wind-power electricity generation.What above-mentioned two kinds of methods all existed is that turbine machine driving generator is lower than motor driven energy utilization ratio, next is delivery pressure and flow that pressurized gas can not be set up gas, thereby can not control the stability of output voltage and frequency, do not reach national grid usage requirement, it three is not consider safety control measure.
The present invention has adopted tandem windsurfing device to drive main shaft to rotate with water movement, and whole system comprises that a plurality of windsurfings are connected into an annular chain, walks around main shaft and rear axle, by floating platform, supports whole system weights.The quantity energy regulating system that changes windsurfing is obtained the size of water energy, windsurfing passes to drive sprocket axle by the energy obtaining, drive sprocket axle drives air compression plant to fill pressure air to the fixedly floating platform of high-pressure bottle formula by speeder, finally by pressure air, drives pneumatic motor to drive generator set to generate electricity.
Recently because sea of Japan seismic sea wave causes nuclear power station blast, cause nuclear leakage, the mankind are trapped among fearful core crisis, find and utilize safe environment protection type new energy imperative, the present invention can provide safety and environmental protection reproducible new energy for the mankind.The generating of Ke Yong river, land, ocean current power generation can be used in ocean, and this technology is applied to wind-power electricity generation, seawave power generation again, can meet human needs completely, and nuclear power station cost is also much lower relatively.
