Figure 2 is a plan view showing a vertical axis wind power generator according to the present invention.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing a vertical axis wind power generator according to the present invention, Figure 2 is a plan view showing a vertical axis wind power generator according to the present invention.

The vertical axis wind turbine generator according to the present invention is a generator 10, the rotating shaft 20, the upper arc support 30, the lower arc support 40, the blade 50 and the auxiliary blade 60 It is configured to include.

Since the generator 10 may use a generator used in a conventional wind turbine, a detailed description thereof will be omitted. The rotary shaft 20 is rotatably coupled with the lower end of the generator 10 and extends vertically upward from the portion coupled with the generator 10. The configuration of the rotary shaft 20 is also found in all conventional vertical shaft wind turbines.

Lower and upper circular arc supporters 40 and upper arc supporters 30 are respectively coupled to the lower and upper portions of the rotation shaft 20. The upper arc-shaped support 30 and the lower arc-shaped support 40 are the same size and shape, the difference is that the upper arc-shaped support 30 is coupled to the upper portion of the rotation shaft 20, the lower arc-shaped support 40 is coupled to the lower portion of the rotary shaft (20).

The upper arc-shaped support 30 and the lower arc-shaped support 40, as shown in FIG. However, it does not have to be shaped like an arc of a semicircle, but just curved and curved.

One end of the upper arc-shaped support 30 and the lower arc-shaped support 40 is combined with the rotating shaft 20 extends horizontally outward from the rotating shaft 20 which is the center, the upper arc-shaped support 30 and Lower arcuate support 40 is coupled to the rotating shaft 20 at regular intervals of three each. However, the upper arc-shaped support 30 and the lower arc-shaped support 40 are not necessarily three, but may be more, but considering the weight to install three is excellent in terms of efficiency.

At this time, the lower arc-shaped support 40 is located at a position corresponding to the vertically lower portion of the upper arc-shaped support 30, and as shown in FIG. 2, the lower arc-shaped support 40 is the upper arc-shaped support 30. Overlapping with In addition, as shown in FIG. 2, when viewed from above, both the upper arcuate support 30 and the lower arcuate support 40 are equally bent in the clockwise direction outwardly from the axis of rotation 20, or are all the same in half. Bent clockwise.

The blade 50 and the auxiliary blade 60 have a semicircular pipe shape in which the horizontal cross section has a semicircular shape. However, the shape of the blade 50 and the auxiliary blade 60 does not necessarily have to have a semicircular cross section, and one surface may have a concave surface and a convex surface. The blade 50 extends in the vertical direction, the upper end of the blade 50 is coupled to the outer distal end of the upper arcuate support 30 and the lower end of the blade 50 is outside the lower arcuate support 40 Binds to the distal end; The auxiliary blade 60 extends in the vertical direction, and an upper end portion of the auxiliary blade 60 is between the rotation axis 20 and the half of the entire length of the upper arc-shaped support 30 of the upper arc-shaped support 30. Coupled to a portion located at the lower end portion of the auxiliary blade 60 is located between the portion of the lower arc-shaped support 40 between the rotation axis 20 and the half of the full length of the lower arc-shaped support 40 To combine.

In addition, the blade 50 and the auxiliary blade 60 is coupled to the upper arcuate support 30 and the lower arcuate support 40 when they are bent clockwise from the rotation shaft 20 as shown in FIG. 2. The upper arc-shaped support 30 and the lower arc-shaped support 40 are coupled to protrude convexly in a counterclockwise direction when viewed about the rotation axis 20, and the upper arc-shaped support 30 and the lower arc-shaped support ( When the 40 is bent in the counterclockwise direction from the rotation shaft 20, the projection protrudes in the clockwise direction when viewed about the rotation shaft 20 from the upper arc support 30 and the lower arc support 40 coupled thereto. To be combined.

On the other hand, between the blade 50 and the auxiliary blade 60, and between the auxiliary blade 60 and the rotating shaft 20 is formed in the horizontal direction. The weight of the structure supported by the rotating shaft 20 is greatly reduced by constructing a large number of perforated portions between the upper arc supporter 30 and the lower arc supporter 40.

Referring to the operation of the vertical axis wind power generator according to the present invention configured as described above are as follows.

When the wind blows, the concave surfaces of the blade 50 and the auxiliary blade 60 receive the wind and go round with the rotating shaft 20 in the opposite direction. The convex portions of the blade 50 and the auxiliary blade 60 are blown by the wind. Orientation is due to the convex portions of the blade 50 and the auxiliary blade 60, the drag which is a force against the wind is reduced. Since the blade 50 is located farthest from the rotation shaft 20, the rotational torque is the largest so that the rotation shaft 20 is sharply rotated, and the auxiliary blade 60 rotates any blade 50 according to the rotation of the blade 50. The concave surface of the blade 50 allows to receive the wind even in a certain section where the wind is not well received. At this time, the upper arc-shaped support 30 and the lower arc-shaped support 40 to bear the blade 50 and the auxiliary blade 60 at the top and bottom, respectively, because it forms a semi-circular arc shape can withstand strong winds well.

As described above, the present invention has been described only with respect to specific examples, but it will be apparent to those skilled in the art that various changes and modifications can be made within the technical spirit of the present invention based on the above specific examples. And modifications belong to the appended claims.
