Abstract
The utility model discloses a 2.0MW57 rice aerogenerator blade, including the blade casing, this aerogenerator blade is laid by the glass fiber cloth of laminating blade mould and is formed, lays the glass fiber girder of high -modulus in the middle of the blade casing, and the tiling of glass fiber girder both sides has PVC foam and cork wood layer. Blade length increases, sweeps the long -pending increase of windpiston, and the wind energy of acquireing is the increase just, has increased blade power, the glass fiber girder of the adoption high -modulus of blade has improved the intensity of blade, has reduced blade weight, through the improvement of wing section, improved the rotational speed of blade, reduced the volume and the weight of directly driving the formula generator, reduce manufacturing cost.
Description
Technical field
The utility model relates to a kind of blade of wind-driven generator, particularly relates to a kind of 2.0MW/57 rice blade of wind-driven generator.
Background technique
Wind power technology is since the development seventies in last century, and single-machine capacity develops into MW class from multikilowatt, and global electric motor power has reached 282,000,000 kilowatts.Blower fan type is double-fed type and directly driving type blower fan mainly, and installation region is marched from land, intertidal zone to sea.China is since Renewable Energy Law in 2006 is promulgated, wind-powered electricity generation obtains and develops fast, and current electric motor power has reached 7532.4 ten thousand kilowatts.Development of Wind Power In China ubiquity serious problems, be exactly that wind-powered electricity generation almost spreads over Chinese North China, northwest, Northeast Regional, the wind-resources in this region is good, and wind energy utilization efficiency is high; But due to transformation, the industry problem such as less-developed of electrical network, cause the wind-powered electricity generation in such region to be substantially in unserviceable situation.Chinese industrial is flourishing, be badly in need of the region of green energy resource development in East China, southwest, South China Regional, and the wind-resources in this type of region is undesirable, is substantially in four Lei Feng districts.From the angle of energy conservation, if obtain specified power, the shortage of wind-resources must be made up by the length increasing blade.Therefore, develop overlength fan blade and carry out the inexorable trend that satisfied southern wind-power market is the development of current wind-power electricity generation.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of 2.0MW/57 rice blade of wind-driven generator.There is the shear web that intensity is large, rigidity is large.
The technical solution adopted in the utility model is:
A kind of 2.0MW/57 rice blade of wind-driven generator, comprise blade shell, this blade of wind-driven generator is laid by the glass fiber cloth of blade mold of fitting and is formed, and is equipped with the glass fibre girder of high-modulus in the middle of described blade shell, and the tiling of described glass fibre girder both sides has PVC foam and cork wood layer.
Further, the glass fibre girder of suction surface blade shell is fixedly connected with web by adhesive, the two ends of described web are fixed on the glass fibre girder of suction surface.
Further, the length of blade of wind-driven generator is 57 meters.
Further, the maximum chord length of blade of wind-driven generator is 3.7 meters, and the maximum pre-bending of blade of wind-driven generator is 4.0 meters.
The beneficial effects of the utility model:
1, length of blade increases, and wind sweeping area increases, and the wind energy of acquisition just increases, and its wind district being useful in 9.0m/s uses, and expands Applicable scope, adds fan power;
2, the glass fibre girder of the employing high-modulus of blade, improves the intensity of blade, reduces leaf weight and is about 1000Kg;
3, by the improvement of aerofoil profile, improve the rotating speed of blade, bring up to 14.5rpm by common 12rpm, reduce the volume and weight of direct drive generator, reduce cost of production;
4, new blade blade tip adopts flexible design, reaches the object reducing blade loading further.
