Abstract
A wind power generator comprises a generator and wind wheels, which is characterized in that the wind wheels are specially shaped, wherein the section of the body of each wind wheel is specially shaped, formed by a straight section and/or an arch section. The special shape is umbellate-shape, hook-shape T-shape or L-shape. The utility model provides a wind power generator, having low wind resistance, thus is beneficial for the start and generation of the wind power generator from low wind speed, and the wind power generator has strong wind catch ability and high wind energy utilization factor.
Description
Technical field
The utility model relates to a kind of wind-driven generator, belongs to the wind-driven generator field.
Background technique
The more options annual mean wind speed is that 6m/s or above high wind speed district build Large-scale Wind Turbines both at home and abroad.The area of China's 76% area, annual mean wind speed are 3～5m/s, because wind speed is little unstable again, do not reach the requirement of wind energy turbine set addressing, but are fit to promote small-sized wind power generator.It is that bigger advantage is arranged that H type vertical axis aerogenerator starts generating for low wind speed, and the higher vertical axis aerogenerator of power coefficient is also fewer at present.
Summary of the invention
Technical problem to be solved in the utility model is to provide power coefficient higher a kind of wind-driven generator.
The technical solution of the utility model is as follows:
A kind of wind-driven generator comprises generator, fan blade, it is characterized in that, described fan blade is a special-shaped fan blade, and promptly the sectional shape of wind blade main body (main lobe) is special-shaped shape, and special-shaped shape is made up of straightway and/or arc.
Above-mentioned wind-driven generator, described wind blade main body is cross section special-shaped to be shaped as the umbrella shape shape, or hook-like shape, or T shape shape, or shape.
Above-mentioned wind-driven generator, described wind blade main body cross section umbrella shape shape can be circular arc umbrella shape shape, or bullet umbrella shape shape, or wedge angle umbrella shape shape, or trapezoidal umbrella shape shape, or fillet hypotenuse umbrella shape shape, or the like.Straightway and/or camber line are done variation slightly, also can make other umbrella shape shapes, do not enumerate one by one here.
Above-mentioned wind-driven generator, described wind blade main body cross section hook-like shape can be single hook-like shape, or double hook shape shape.Straightway and/or camber line are done variation slightly, can make multiple single hook-like shape, double hook shape shape.
Above-mentioned wind-driven generator, described fan blade can be spliced into a fan blade from beginning to end by two or more special-shaped fan blades.Connecting method can be grafting, snapping, axle connection, welding or riveted joint.
Above-mentioned wind-driven generator, described fan blade, material can adopt aluminum alloy, glass fibre reinforced plastics, composite material, or is made of high strength fibre cloth, skeleton.Skeleton is metal or composite material.High strength fibre cloth is carbon fibre cloth, or aryl fiber cloth, or high-module high-strength polyethylene fibre cloth, or basalt fiber cloth or the like.
When above-mentioned wind-driven generator, described fan blade, material adopted high strength fibre cloth, skeleton formation, high strength fibre cloth can be fixing, or the extension contraction.The extension of high strength fibre cloth is shunk, and can realize by the motor, pulley, the rope that are located on the skeleton.
Above-mentioned wind-driven generator is mainly vertical axis aerogenerator.If when adopting sectional shape to be the fan blade of single hook-like shape, above-mentioned wind-driven generator can also be a horizontal axis wind-driven generator.
Advantage of the present utility model and beneficial effect:
A kind of wind-driven generator of the utility model, windage is little, help the low wind speed of wind-driven generator and start generating, and it is strong to catch wind energy power, has higher power coefficient.

Embodiment
As shown in Figure 1, be a vertical axis aerogenerator.1 is generator, and 2 is fan blade, and 3 is support arm.Generator 1 is to couple together by support arm 3 with fan blade 2.One end of support arm 3 connects generator 1, and the other end connects fan blade 2.Generator adopts outer rotor generator in this embodiment.
Fig. 2 to Fig. 9 is the sectional view of the more representational fan blade of the utility model.With the aluminum alloy material is example, according to the required width of fan blade, thickness, can adopt aluminium alloy extruded mode, and the section bar of extruding all-in-one-piece odd-shaped cross section cuts into required length again, can obtain the required fan blade of the utility model.Or, cutting into required length along the tangential segmentation extruding of fan blade, splicing gets final product again.
