Description

Windmill fan blade combination in the shape of a meter

The present invention relates to a wind power generator, and more particularly to a wind turbine blade combination in which a windmill is increased in size and a wind turbine blade is combined in a m-shape to maintain output speed stability. Background technique

With the development of civilization, technology has been constantly advancing, and patents are constantly improving. As invented by the inventor, Taiwan Patent No. 096214228 (Patent Registration No. M331580) "Large Safety and High Efficiency Windmill" patent (the patent number in China is ZL961200928), which provides a design for the large-scale windmill to Reduce investment costs and increase power generation revenue. At the same time, it can greatly improve the safety of the windmill system and reduce the loss of personnel or materials.

However, after a long-term test, the aforementioned patents found that there are still shortcomings that should be improved. First, referring to FIG. 1 and FIG. 1A, when the combination of the upper and lower blades of the prior art is in a cross shape (top view), the extra force generated by the flange a at the end of the blade a in the second quadrant causes the whole The rotation speed of the shaft is not uniform. If the generator is driven by the generator, the voltage and frequency will be unstable. The upper blade 7 and the lower blade 8 shown in FIG. 1A alternately form a cross shape, because the flange a of the end of each small blade a is a folded edge at an angle with the blade a. When the blade a enters the side of the downwind, the blade a The wind receiving area is increased from small to large (as shown in Fig. 2A from X to y), and when the wind direction is 90 degrees, the wind receiving area of the blade a is the largest. When the blade a receives the largest wind area, it turns 180 degrees with the wind direction, g卩:

(1) The blade a is gradually reduced by the wind surface;

(2) When the blade a is at 90 degrees, the area of the blade of the upper blade 7 or the lower blade 8 just entering the wind receiving side gradually increases, and the gradually increasing blade area compensates for the blade area which has been gradually reduced with the wind receiving surface, so Maintaining the same area of the blade output speed is the same, the output is the same;

(3) When the blade a is turned from 90 degrees to 180 degrees y, the end flange 71 of the upper blade 7 starts to generate force until it is parallel with the wind direction (when the position of z) is stopped (as shown in FIG. 2A), The force curve is y-xl-x2, because the blade is in the shape of a cross, at this time, the flange 81 on the outer side of the lower blade 8 starts to generate force (as shown in Fig. 2A), and the output curve is χ2- _Χ 3-χ4, due to the blade output 7 and 8 are not continuous, there _Χ output gap 1-χ2-χ3, resulting in uneven speed, driving the generator speed will be unstable.

It can be seen that the traditional combination of windmill blades and blades still has to be improved and needs to be improved. Summary of the invention
