Description
Technical field
The present invention relates to a kind of unsteady no axle collar type vertical vane wind energy engine, belong to the wind energy power technology field.
Background technique
THE WIND ENERGY RESOURCES IN CHINA is abundant.According to the initial estimate of China Meterological Science Research Institute, be 2.53 hundred million kw but China land 10m highly locates development reserves, but the sea development reserves are 7.5 hundred million kw, total reaches 1,000,000,000 kw approximately, and Wind Power Utilization has a high potential.
The main mode of modern Wind Power Utilization is a wind-power electricity generation, and the superiority of wind-power electricity generation: ⑴ builds the cost of wind power plant, and is more much lower than the expenditure of construction of hydroelectric power station, thermal power plant or nuclear power station; ⑵ wind-force is a kind of natural energy resources of cleaning, does not have the environmental pollution problem of coal electricity, oil electricity and the association of nuclear power institute; ⑶ do not have coal electricity, oil electricity and any other required fuel consumption of nuclear power except that the routine maintenance, operating cost is low; ⑷ the most important thing is, wind is a kind of renewable, pollution-free and energy that reserves are huge.Along with global warming and energy crisis, each state of the whole world reduces carbon dioxide isothermal chamber gas purging, the earth of protecting us to depend on for existence all in the development and utilization that steps up wind-force as far as possible.The core of wind-power electricity generation is a wind turbine, and wind turbine is a wind-force cumulative device, is divided into two big types of horizontal axis and vertical shaftes, and the scale wind-power generating system that uses at present mainly is horizontal shaft type wind-force cumulative device.The cumulative but horizontal shaft type wind energy engine must facing the wind, Wind Power Utilization space basically can only be in tens of meters spaces below 100 meters more than the face of land, and the electric power output of continous-stable can not be provided, and the unit installed power is very limited.As, Denmark has more than 3000 of wind-driven generator at present, but only 10,000,000,000 degree that generate electricity in year.At a rough estimate, only at this level, recent available wind energy total output is about 10～10,000,000,000 kw, and this numerical value is big 10 times than the utilizable waterpower resourses in the whole world.If can utilize the wind-force of thousands of meters high-altitude scopes, wind energy even can directly offer the electric power that our whole world is used so.The annual wind-powered electricity generation adding new capacity of China is doubled year after year since 2005.Wherein, electric motor power in 2005 reaches 1,260,000 kw, has surpassed 1,000 ten thousand kw to wind-powered electricity generation electric motor power in the end of the year 2008.Show according to the up-to-date report of GWEC (GWRC): 2010, the wind energy capacity of newly-increased 1,890 ten thousand kw of China, thus make total installation of generating capacity reach 4,470 ten thousand kw.
Natural wind speed, wind direction can acute variation occur with the difference of altitude, and there is not the windward side problem in large-scale vertical vane wind energy engine, can assemble the energy of the different wind directions on the different level simultaneously.But the perpendicular axis type wind energy engine of present non-mainstream use exists equally that cumulative power is little, efficient is low and problem such as electric power output instability.
Summary of the invention
