Description
Technical field
The utility model relates to technical field of wind power generation, specifically, and particularly a kind of blade of wind-driven generator.
Background technique
Outburst along with each energy crisis; And the reserves of petroleum resources are not unlimited, and the reserves that can exploit and utilize at present are few, therefore; People must estimate the crisis that the fossil energy resource exhaustion possibly bring, and exploration that should be as early as possible, research and develop and utilize novel energy.Generation along with the nuclear leakage incident of Chernobyl accident and Fukushima, Japan nuclear power station impels people to seek the new energy of safe green all the more.
Wind-force is the very big new energy of a kind of potentiality, and once the someone estimated, the wind resource that can be used to generate electricity on the earth has 10,000,000,000 kilowatts approximately, almost is 10 times of present whole world hydroelectric power amount.The present energy that obtained of the annual coal combustion in the whole world, only account for wind-force in 1 year the energy that provides 1/3rd.Therefore, all take much count of both at home and abroad utilizing wind-force to generate electricity, tap a new source of energy.The principle of wind-power electricity generation is to utilize wind-force to drive the air vane rotation, and these blades become to drive the rotatory force of one or more generators with wind energy transformation, thereby change wind energy into electric energy through mechanical energy.
As the free of contamination energy of a kind of environmental protection, in the global range, wind-power electricity generation more and more comes into one's own and develops; Particularly in countries such as Finland, Denmark; At present, China also advocates just energetically, because it need not use fuel; Also can not produce radiation or atmospheric pollution, it has the incomparable advantage of other energy.
