?-shaped fan blade combination for windmill

TECHNICAL FIELD The windmill blades were shaped rice

The present invention relates to a wind power generator, in particular refers to a large-scale windmill, windmill blades by the combination was rice-shaped manner, in order to maintain a stable output speed combination for the purpose of windmill blades. Background technique

With the development of civilization, science and technology has been constantly into ho, patents are also constantly improving. As the inventors previously filed the first China Taiwan No. 096 214 228 (Patent Registration No. M331580) "safe and efficient large-scale windmill" patent (in the case of Chinese patent number is ZL961200928), which provides a large-scale windmill designed to reducing investment costs, thus increasing revenue generation. At the same time can significantly improve the security of the windmill system, reduce the loss of personnel or materiel.

But the aforementioned patents After a long test, find that there is drawback shall be improved. First, please refer to FIG. 1, 1A, a prior art compositions on the blade when the lower layer is cross-shaped (top view) the way that the leaves of a folding al additional output terminal makes the entire second quadrant generated shaft speed does not mean, at this time if the temerity to drive a generator, will cause voltage and frequency instability. Upper blade shown in FIG. 1A 7-8 lower leaves were interactive cross, because every little blade end of a blade with a hem al an angle of folding, when entering the downwind side of a blade, a blade when the wind area from small to large (FIG. 2A from the X to the point y) 90 degrees to the wind, the blades of a wind largest. When a wind vane largest area, the wind turned 180 degrees, g Jie:

(1) decreased by a wind vane surface;

(2) When a blade 90 degrees, the upper or the lower blade 7 blade 8 has just entered the wind side of the leaf area gradually increased, the gradual increase in leaf area and that has to make up for the decreasing wind blade surface area, so they can the same area of ​​the blade to maintain the same output speed, output the same;

(3) When a blade from 90 degree turn 180 y position of the upper tip of the blade 7 of 71 began hemming (z position) is output to the wind direction was parallel with the output stop (shown in Figure 2A), which the Force curve for the y-xl-x2, because the leaves into a cross, this time outside of hemming the lower blade 8 81 began to produce output (shown in Figure 2A), the output curve χ2-_Χ3-χ4, since the blade 7 and 8 output discontinuity, there _Χ1-χ2-χ3 the output gap, resulting in uneven speed, the speed will be unstable when driven generator.

Thus, the combination of traditional windmill blades place while still not entirely be be improved. SUMMARY

The main object of the present invention is to provide a combination of rice-shaped windmill blades were, to increase its blade, so that the power of the majority of the leaf area which is concentrated on the vertical axis, but its weight and shaking when they are dispersed in operation on the whole structure, so large-scale blade is safe.
