However, in the invention described in Patent Document 1, since the wind guide plate is excessively installed in the surrounding area, the wind guide plate becomes resistant to the wind flowing in and out of the wind, and the wind blow-off is bad, and therefore the windmill Since the flow velocity of the wind blown on the wing drops due to resistance, there is a problem that the efficiency of the windmill is not improved as a result.
Further, the invention described in Patent Document 2 has a problem that the structure of a windmill, fixed wings, and the like is too complicated, and is expensive compared to other devices.
And in the invention described in patent document 3, there existed a problem that a windmill could receive only the wind from a fixed direction by installing a guide plate so that a windmill might be covered.

  An object of the present invention is to provide a wind turbine device that is inexpensive, versatile, simple in structure, and efficient without impairing its advantages by using two types of rectifying plates for a vertical axis wind turbine device.

  In order to achieve the above object, a vertical axis wind turbine apparatus according to the present invention comprises a wind turbine blade and a rectifying plate device having a plurality of two kinds of rectifying plates whose directions can be moved, and a support frame for fixing the rectifying plate. Has been. The wind turbine blades are those of vertical axis type wind turbine blades, and there are two types of rectifying plates: a first rectifying plate in the shape of a wing and a second rectifying plate obtained by cutting the first rectifying plate in half in the thickness direction. is there.

In the vertical axis wind turbine apparatus of the present invention, the direction of the blowing wind changes depending on the angle of the first rectifying plate and the second rectifying plate. Due to the shape of the current plate, the side with the bulges bends better and merges with the wind that hits the flat side. The direction of the wind is changed by the first rectifying plate and the second rectifying plate, and the wind is concentrated on the wind turbine blade on one side that can receive the drag force of the blowing wind. The wind turbine blade on the opposite side is hit by the wind weakened by the second rectifying plate.
The wind that blows in the direction of rotation of the windmill can be converged, or the wind that blows in the direction of rotation can be weakened.

  According to the vertical axis type wind turbine apparatus of the present invention, the wind is concentrated on the wind turbine blades on one side as described above, so that the rotational speed of the wind turbine is increased. Further, since the wind turbine blade on the opposite side is subjected to weakened wind, the rotational resistance of the wind turbine is reduced. Therefore, since the wind energy is concentrated on a part of the wind turbine used, the rotational efficiency of the wind turbine is improved as compared with the conventional vertical axis wind turbine. Moreover, this windmill apparatus is simple in structure, and can respond to various types of windmill blades by changing the size, shape, and orientation of the current plate of the current plate apparatus. And it inherits the advantages of a vertical axis wind turbine.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention applied to a vertical axis wind turbine device will be specifically described below with reference to the drawings.
As shown in FIG. 1, the vertical axis wind turbine apparatus according to the present invention alternately rectifies a plurality of first rectifying plates (1) and second rectifying plates (2) around the vertical axis type wind turbine apparatus (4). Install at the plate installation angle (8). A support frame (6) is used to fix each current plate. All installed baffles rotate within the range of movable angle (3). As shown in FIG. 3, the shape of the rectifying plate is such that the first rectifying plate (1) has an airfoil cross-sectional shape having an outline in which two arcs bulging outward are connected to each other at both ends. The second rectifying plate (2) has an airfoil cross-sectional shape having a contour in which one arc line and one straight line bulging outward are connected to each other at both ends.

  In FIG. 2, the wind turbine device (4) is connected to the generator (7), the boundary surface (10), the wind flow (9), the wind flow (11) introduced into the device, and repelled outside the device. Wind flow (12) is shown. In addition, the wall that cannot be seen as the boundary surface, the wind inside the boundary surface is changed by the rectifying plate and the direction of the wind is changed and concentrated in the rotation direction of the rotor. Decrease. Further, the position of the boundary surface changes depending on the wind direction. As shown in the figure, the wind flowing in the vicinity of the first rectifying plate is bent in a direction along the installation angle (8) of the rectifying plate. The wind that flows in the vicinity of the second rectifying plate flows in the direction of rotation of the vertical axis type windmill when the wind passes through one side of the rectifying plate, and flows in the direction that does not affect the rotation of the vertical axis type windmill. As a result, wind concentrates on the wind turbine blades on one side, and the rotational speed of the wind turbine increases. Further, since the wind turbine blade on the opposite side is subjected to weakened wind, the rotational resistance of the wind turbine is reduced. As a result, the efficiency of the vertical axis wind turbine device is improved.
