Abstract
The utility model discloses a 2.0MW/54m low-wind-speed super-long type power turbine generator blade. The wind turbine generator blade comprises a blade casing, a glass fiber main beam and a web. The blade casing comprises a suction face and a pressure face, the glass fiber main beam is laid in the middle of the blade casing, flat plates are arranged on the two sides of the glass fiber main beam, and the web is fixed to the suction face of the glass fiber main beam. The 2.0MW/54m low-wind-speed super-long type power turbine generator blade has the advantages that the blade length is increased, the wind sweeping area is enlarged, obtained wind energy is increased, the wind turbine generator blade is suitable for areas with the wind speed of 10.5m/s, the using range is expanded, and the blade power is improved. By means of the high-modulus glass fiber main beam, the blade strength is improved, and the blade weight is reduced by 1500Kg. Due to wing section improvement, the blade rotation speed is improved from general 15rpm to 17rpm, the size of a direct-driving power generator is reduced, the weight of the direct-driving power generator is reduced, and the production cost is reduced. Due to the fact that the blade tip is in the pre-bent design, the purpose of further reducing the blade load is achieved.
Description
Technical field
The utility model relates to a kind of blade of wind-driven generator, relates in particular to the low wind speed overlength of a kind of 2.0MW/54 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 mainly double-fed type and directly driving type blower fan, and installation region is marched to sea from land, intertidal zone.China is since Renewable Energy Law in 2006 is promulgated, wind-powered electricity generation has obtained development fast, and electric motor power has at present reached 7532.4 ten thousand kilowatts.Serious problems of Development of Wind Power In China ubiquity, are exactly that wind-powered electricity generation almost spreads over Chinese North China, northwest, Northeast Regional, and the wind-resources in this region is good, and wind energy utilization efficiency is high; But due to problems such as the transformation of electrical network, industry are less-developed, cause the wind-powered electricity generation in such region substantially in unserviceable situation.Chinese industrial prosperity, be badly in need of green energy resource development region in East China, southwest, South China Regional, and the wind-resources in this type of region is undesirable, substantially in Si Leifeng district.From the angle of energy conservation, if obtain specified power, must make up by increasing the length of blade the shortage of wind-resources.Therefore, exploitation overlength fan blade meets the inexorable trend that southern wind-power market is current wind-power electricity generation development.
Model utility content
The utility model discloses the low wind speed overlength of the 2.0MW/54 rice blade of wind-driven generator that a kind of intensity is large, rigidity is large.
The technical solution adopted in the utility model: the low wind speed overlength of a kind of 2.0MW/54 rice blade of wind-driven generator comprises blade shell, glass fibre girder and web, blade shell comprises suction surface and pressure side, the middle lay glass fibre girder of blade shell, the both sides of glass fibre girder are provided with tiling plate, on the glass fibre girder of suction surface, are fixed with web.
Blade shell is laid and is formed by glass fiber cloth, and the material of tiling plate is PVC foam.
Further, the length of blade shell is 54m, and the maximum chord length of blade shell is 3.7m, and maximum pre-bending is 4m, and the root bolt pitch diameter of blade shell is 2110mm, 60 of Number of Bolts.
The beneficial effects of the utility model: length of blade increases, wind sweeping area increases, and the wind energy of obtaining increases, and in the wind speed region of 10.5m/s, is all suitable for, and has expanded using scope, has increased blade power; Blade adopts the glass fibre girder of high-modulus, has improved the intensity of blade, has reduced the about 1500Kg of weight of blade; By the improvement to aerofoil profile, improve the rotating speed of blade, there is common 15rpm to bring up to 17rmp, reduce the volume and weight of direct drive generator, reduce cost of production; The blade tip of blade adopts the design of pre-bending, reaches the object of further reduction blade loading.
