Description
Technical field
The present invention relates to a kind of blade and use the wind power generating set of this blade, particularly a kind of wind power generating set that is used for the blade of wind generating unit and uses this blade.
Background technique
As can be wind energy being transformed to the windmill of power than higher energy conversion efficiency, the known in the past running shaft that to have with Dutch type windmill be representative with respect to the horizontal axis type windmill of eolian level and running shaft with respect to eolian vertical vertical shaft windmill.
Wherein, the horizontal axis type windmill adopts in the major part of large-scale windmill; For vertical shaft windmill, shortcoming with the self-starting when lacking weak wind, do not need fully the following control, on which direction of the four corners of the world, all equally bring into play the advantage of performance of wind direction but have, expect its development and application therefore especially as the small-sized windmill that is suitable for the setting in city and the life range.
Vertical shaft windmill is known to be included and is used in the resistance that produces on the blade rotates the resistance-type vertical axis type windmill of windmill and be used in the lift vertical shaft type windmill that the lifting power that produces on the blade is rotated windmill as Darrius type and gyroscope type etc. as paddle type and Sa Funiusi type etc.; Resistance-type vertical axis type windmill will reduce towards the resistance of the blade of direction against the wind, utilize resistance difference to make the windmill rotation, and relative with it, lift vertical shaft type windmill is to utilize the lift that produces on blade to make the windmill rotation.
; resistance-type vertical axis type windmill just can not produce the moment that windmill is rotated quickly when all speed ratios (the wing tip speed/wind speed of blade) when being 1, though thereby just exist wind speed to rise; but can not obtain surpassing the rotating speed of wind speed, generating efficiency is hanged down such problem; On the other hand, though all speed ratios of lift vertical shaft type windmill 1 when above, the aerodynamic characteristics of windmill improves, and windmill is rotated efficiently, when all speed ratios 1 when following, the aerodynamic characteristics variation of windmill, the moment of rotating windmill diminishes.In addition, also have starting torque little, start the very shortcoming of difficulty that becomes from halted state.
As Fig. 1, Fig. 2, shown in Figure 3, existing wind generating unit is made of running shaft 1, generator 2 and two pairs of blades 3, running shaft 1 upper and lower end is respectively arranged with land 5, land 5 is used to connect two pairs of blades 3 and the land that is arranged on the running shaft 1 by connecting rod 4, and running shaft 1 is rotatable; Wind generating unit drives blade 3 by wind-force, and blade 3 rotates by connecting rod 4 driven rotary axles 1, thereby makes generator 2 work that are arranged on running shaft 1 bottom.
The sectional shape of the aerofoil profile of blade 3 be similar (being similar to) in the section configuration of aircraft main wing, rotating force A blows wind from the side surface direction of blade 3, produces lift in the front of blade 3, thereby drives the blade rotation.
And, blade 3 is connected the plat part 4b of connecting plate 4a in the existing wind generating unit by connecting rod 4, when running into long-time high wind, when in use, blade 3 can produce pressure to the plat part 4b of connecting plate 4a, in order to guarantee the soundness of blade 3 and connecting plate 4a, just need carry out material thickening or heat treatment to part relatively more fragile on the blade 3, but this method can increase the weight of blade 3 or make the processing difficulties of blade 3, has increased cost greatly.
