Description

Blade of wind power generator

The present invention relates to a blade of a wind turbine, and more particularly, to a variable structure of the blade of the wind turbine capable of actively embracing the wind blowing toward the blade.

In general, blades used in wind power generators can increase power generation efficiency only if they can actively embrace the blowing wind.

Conventionally, various types of blades have been developed to increase the wind capacity.

As an example, there has been a technique of increasing the capacity of the wind by forming the blade of the blade to be swollen by the wind, and before that, there has been an effort to increase the capacity by changing the shape and structure of the blade.

However, the techniques developed in the past have been limited in increasing the blade's capacity in this way because the blade is only blown in place.

As a conventional known technology for solving such a problem, "vertical wind power generator" of Republic of Korea Patent No. 10-0485494 is disclosed through Figs.

1 is a perspective view showing a vertical wind power generator according to the prior art, Figure 2 is a plan view schematically showing the vertical wind power generator of Figure 1 to explain the operation relationship between the wind vane and the impeller by the wind, Figure 3 Is a partial cross-sectional view schematically showing a part of a vertical wind power generator according to the prior art.

The vertical wind power generator of the prior art as shown in the figure is connected to the generator (2) at the bottom of the main shaft (1), a plurality of upper connecting shaft (3) and the lower connection radially from the main shaft (1) The shaft 5 extends, and the impeller 11 is mounted between the upper connecting shaft 3 and the lower connecting shaft 5, respectively, and the impeller 11 is wind vane through the wing front angle adjusting device 31. Connected with (7).

The vertical wind turbine operates as follows.

The wind vane 7 is always aligned in a straight line in the wind blowing direction. Therefore, assuming that the wind blows in the X-axis direction, the wind vane 7 is always aligned in the X-axis direction, but the impeller always rotates clockwise with a large rotation moment, so that the wing front angle adjusting device 31 (Fig. 1). The impeller 11 is arranged to have a constant angle in the direction of the wind portion, and at the same time, the circumferential movement is performed clockwise around the main shaft 1 by the wind.

That is, when the wind vane 7 and the impeller 11a are positioned in the X-axis direction at the a position, and the impeller is positioned at the b position by the circumferential movement (orbit), the wind vane 7 is rotated to match the direction of the wind. The impeller 11b is inclined in the direction of −45 degrees with respect to the X axis by the vane angle adjusting device 15 by the rotation angle of the wind vane 7, and the impeller is driven around the main shaft 1. By further rotating to reach the c position, the wind vane 7 is rotated to coincide with the direction of the wind, so that the wing front angle adjusting device 15 transmits the rotation angle of the wind vane 7 to the impeller 11c. (11c) is rotated by -90 degrees perpendicular to the direction of the wind, the impeller 11d by the wind vane 7 and the wing front angle adjuster 15 in the d position is -125 degrees to the direction of the wind It is arranged to be inclined.

Therefore, the impeller always carries the wind and circumferentially moves in one direction with a large rotation moment by the wing front angle adjusting device 31 which transmits the angular rotation of the wind vane to the impeller, and the main shaft 1 by the circumferential movement of the impeller. By rotating), the generator 2 arranged at the lower end of the main shaft 1 is generated.

As an example, the wind is blown in the 0 degree direction from above, but the impeller is disposed at the position illustrated above because the wind vane 7 is always aligned in a direction in which the wind is blown in any direction.

In addition, in the related art as described above, the circumferential motion and rotation ratio of the impeller 11 are most preferably 2: 1.

As described above, the wind vane is always placed in the direction of the wind when the wind is blowing, but for the wing front angle adjuster 31 which allows the impeller 11 to be placed in front of the direction of the wind. This will be described in detail.
