Abstract

PROBLEM TO BE SOLVED: To increase the areas of a side rotating against wind and a side rotating with the reception of wind, so as to generate a large rotating force by fixing a lattice-like frame orthogonally or radially, and pivotally mounting a plurality of separation wind receiving plates capable of rotating to one surface of each frame. SOLUTION: A plurality of lattice-like frames 3 are arranged or thogonally or radially on a rotational shaft 1 of a vertical shaft type windmill. A plurality of separation wind receiving plates 4 capable of rotating are pivotally mounted on only one surface of each frame 3. At the side to receive wind, the plates 4 function as wind receiving vanes as they lean on the frame 3 so as to cover the whole of the frame 3, to thereby receive wind without releasing it. At the side to cause rotation against the wind, the plates 4 of the frame 3 are rotated by the wind force and changed in the mode to pass wind therethrough, so that large rotating force is generated.

Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical axis wind turbine used for wind power generation, for example.

2. Description of the Related Art A vertical axis wind turbine will be described with reference to FIG. A windmill in which a radial integral wind receiving plate 2 is provided on a rotating shaft 1, and a rotational force is obtained by a difference in resistance coefficient applied to the wind receiving plate.

The conventional example has a simple structure in which a rotational force is obtained by a difference between the following resistance coefficients R applied to the integrated wind receiving plate 2 receiving the wind. The simple formula did not lead to a large torque. Accordingly, an object of the present invention is to efficiently extract the rotational force by automatically and greatly reducing the resistance coefficient and the area S of the entire wind receiving plate 6 on the side rotating against the wind, as compared with the conventional method.

SUMMARY OF THE INVENTION The present invention is constructed as described in claim 1, wherein the grid frame 3 is vertically and radially fixed, and a plurality of divided frames which can be rotated only on one side of the grid frame 3 are provided. In a device in which the wind receiving plates 4 are linked, on the side receiving the wind, the divided wind receiving plates 4 are arranged on the windward side of the lattice-shaped frame 3 with respect to the windward side, and become the whole wind receiving plate 5 so that the rotating shaft 1 is formed. The divided wind receiving plate 4 is pivoted to the leeward center, and reaches the leeward and moves to the leeward side. Hinge 6 was provided on one side of lattice frame 3 and one side of divided wind receiving plate 4.

The first embodiment of the present invention will be described below with reference to FIG. One example shown in FIG. 2 is a vertical side 7 of a lattice frame 3 provided radially from the rotation axis 1.
And the corresponding vertical side 8 of the divided wind receiving plate 4 is rotatably joined, and the divided wind receiving plate is vertically mounted, and the whole wind receiving plate 5 receives wind from the windward to generate rotational force. When it is on the side, the lattice-shaped frame 3 and the divided wind receiving plate 4 are in a substantially parallel form, become the whole wind receiving plate 5 and rotate to the leeward, and the divided wind receiver of the whole wind receiving plate 5 rotated to the leeward Board 4
Is rotated around the hinge 6 by the force of the wind, is contoured to the leeward side, and rotates while allowing the wind to escape upwind. Next, a second embodiment will be described with reference to FIG. FIG.
In the example shown in FIG. 3, a vertical side 9 of a lattice-shaped frame 3 provided radially from the rotation shaft 1 and a vertical side 10 of a corresponding divided wind receiving plate 4 are rotatably joined. When the overall wind receiving plate 5 is on the side that receives wind from the wind and generates rotational force, the lattice-shaped frame 3 and the divided wind receiving plate 4 are substantially parallel, and The wind receiving plate 5 rotates to the leeward side, and the divided wind receiving plate 4 of the whole wind receiving plate 5 rotated to the leeward side rotates around the hinge 6 by the force of the wind, and is contoured to the leeward side, and heads toward the windward side as it is. Rotate while letting the wind escape.

According to the wind turbine for wind power generation of the present invention described in claim 1, the difference in area between the side that rotates against the wind and the side that rotates in response to the wind increases, and a large rotational force can be obtained. .
