Description

A kind of vertical three-wing wind wheel
(1) technical field
The present invention is a kind of device of wind power utilization, particularly relates to a kind of wind wheel apparatus structure of gathering wind energy.
(2) background technique
As everyone knows, our only one earth, mineral resources wherein are limited, are not inexhaustible; With coal, rock gas, oil, water conservancy and nuclear matter is that the conventional electric power exploitation of raw material or resource has caused a large amount of environmental pressures, as environmental pollution, acid rain, climatic anomaly, radioactive waste handle, oil reveals or the like.The sustainable development of harmonious society will force people to go to seek the development and utilization of renewable energy sources actively or passively.Wherein important one is exactly development and utilization to wind energy, is that the electric power exploitation of resource is then very small to the influence of environment with the wind energy, has significant environmental friendliness characteristic, is typical clean energy resource.In the moderate breeze district (per hour 20～2.4 kilometers), one 750 kilowatts wind-powered electricity generation machine can substitute the CO of 1179 tons in thermoelectricity plant every year on average 2, 6.9 tons SO 2NO discharging with 4.3 tons.
Wind energy resources is innumerable, and production capacity is abundant.According to the estimation of AWEA (AWAE), if produce the energy total amount that the U.S. can exploit wind energy, the annual burning 20,000,000,000 barrels of crude oil (almost being the whole crude outputs in the present world) that need.But compare with oil, wind energy but is reproducible resource, and is lost and found again, and simultaneously wind energy has the characteristics of independence, can not be subjected to impacts such as price concussion that international dispute causes and embargo.The AWAE measuring and calculating is used prior art in the U.S., utilizes the land development wind energy less than 1%, and State Grid's demand of 20% can be provided.And in 1% the soil, having only 5% to be that equipment installation etc. must be used, other 95% can also continue on for agricultural or pastoral farming.
The relatively abundant area of wind energy resources is outlying mostly, and wind energy development is that outlying district growth of employment, economic development, agricultural land are increased income etc. and to be brought chance.From world wide, wind energy and solar energy industry may become one of industry that job opportunity is maximum in the new century manufacturing industry.
Because wind energy development has huge economy, society, the value of environmental protection and development prospect, wind power technology has had great advance over nearly 20 years, wind-powered electricity generation exploitation speedup in various energy developments is the fastest: global wind-powered electricity generation installation total amount 1997 to 2002 5 in the period of increase by 4 times, increase to 31128 megawatts in 2002 by 7600 megawatts in 1997, increased by 2.3 ten thousand megawatts, average year amplification reaches 32%.And the wind energy price also can be born for power consumer: the preferential price of wind-powered electricity generation that the power company of some U.S. offers the client has reached 2～2.5 cents/kilowatt-hour, this price makes American family have 25% electric power to obtain by buying wind-powered electricity generation, and only need pay 4～5 dollars every month.
Wind energy more and more is subjected to the attention of countries in the world as a kind of renewable energy sources of cleaning.Its amount of accumulateing is huge, and the wind energy in the whole world is about 2.74 * 109MW, and wherein available wind energy is 2 * 107MW, and is also bigger 10 times than the water energy total amount that can develop on the earth.The Chinese feature energy storage capacity is very big, distribution is wide, and only the wind energy content of land is just had an appointment 2.53 hundred million kilowatts.
Along with development of global economy, wind energy market also develops rapidly.Over nearly 5 years, wind energy market, world every year is all with 40% speed increment.Whole world wind-powered electricity generation electric motor power in 1997 has only 7000 megawatts, existing 90,000 megawatts in 2007, and this numeral to 2010 year will be 160,000 megawatts.Estimate in the following 20-25 that wind energy market, the world will increase progressively 25% every year.Along with the development of technological progress and environmental protection cause, wind energy power will can be competed with coal fired power generation fully commercial.
Tenth Five-Year Plan Period, the grid connected wind power of China is developed rapidly.Reach 1,260,000 kilowatts by in June, 2006 whole nation wind-powered electricity generation installation total capacity, occupy the 10th in the world, the 3rd in Asia becomes after Europe, the U.S. and India and develops one of staple market of wind-power electricity generation.
2006, the electric motor power of Chinese wind-powered electricity generation accumulative total reached 2,600,000 kilowatts, and adding new capacity is 1,330,000 kilowatts then, increases by 166% on a year-on-year basis.Expectation is except 5 provinces and regions such as Tibet, Yunnan, Xinjiang, and the wind energy resources of domestic all the other 26 provinces and regions also has 3,200,000,000 kilowatts of electric motor powers can supply exploitation.Wherein, Inner Mongolia Autonomous Region can account for half of 26 provinces and regions for the wind energy resources of exploitation, reaches 14.6 hundred million kilowatts.
The demand of estimating following wind-powered electricity generation unit will grow at top speed, and estimates can reach 3,610,000 kilowatts, 5,050,000 kilowatts and 6,570,000 kilowatts respectively in 2008～2010 years, increases by 50%, 40% and 30%, three annual compound growth rate on year-on-year basis respectively and reaches 40%.
Wind-powered electricity generation develops into the current stage, and its cost performance is forming the competitive advantage with coal electricity, water power.The advantage of wind-powered electricity generation is: ability whenever doubles, and cost just descends 15%, and world's wind-powered electricity generation growth in recent years remains on more than 30% always.Along with the production domesticization of Chinese feature Denso machine and the scale of generating, wind power cost is expected to fall again.Therefore wind-powered electricity generation begins to become more and more investors' the ground by gold.
The main cause that China's wind-powered electricity generation construction lags far behind world development speed is, do not go into overdrive to rely on the dynamo-electric manufacturing industry basis of domestic richness, absorbs to introduce advanced foreign technology the wind-powered electricity generation complete sets of equipment is carried out independent development.The domestic inappreciable wind-powered electricity generation capacity that has built up is the complete sets of equipment of import all almost, causes that wind energy turbine set investment is high, electricity price is high, with thermoelectricity, water power ratio, lacks the market competitiveness.
Under current market situation, China's wind energy industry should accelerate to introduce and absorb external advanced large-scale wind electricity manufacturing technology, add speed wind-power and build localization process, reduce device fabrication and wind field construction cost, form the wind-powered electricity generation complete sets of equipment manufacture base and the wind energy turbine set construction team of in enormous quantities, big capacity, production domesticization, international most advanced level rapidly, play an active part in the international competition of wind energy industry.Accelerate to build large-scale wind generating factory in the abundant area of wind resource, explore the avenue to success that wind-powered electricity generation with Chinese characteristics is built.
German wind-driven generator from the windmill in Tang Jikede epoch mill room to today, people are exploring the clean energy resource that utilizes this nature of wind-force better always.But the centuries, from the windmill to the wind-driven generator, its basic structure there is no great change, and their basic characteristics are: in order to obtain huge wind energy, must have the huge wind wing.For supporting the huge wind wing, must build corresponding high tower.For adapting to the variation of wind direction, empennage or similar structure and the control of adjusting wind wing windward side must be arranged also.And the huge wind wing and root thereof be accept wind-force converting whirler tool can the capacitation device, it simultaneously is again the gravity support that supports whole workpiece, therefore stress is abominable especially, damages easily, therefore very wishes to have the wind wheel structure of a kind of improvement, ameliorative measure.
