In the case of a general wind turbine generator, there is a disadvantage in that a bearing is required between the first housing 100 and the second housing 200 to attenuate wear, thereby further adding components.

However, according to the present invention, there is an effect that the portion of the second housing 200 contacting the first housing 100 is not worn away when the second housing 200 rotates without the configuration of the bearing.

Also, the first housing 100 can include the generator 110, the gear box 120 in which the drive gear is embedded, the controller 130, and the battery 140.

Referring to FIG. 1, although the shape is provided in a triangular shape, it is not limited thereto, and it is preferable that it is provided in an upward convex shape so that it is resistant to wind and floated.

Next, the outer vane 220 may be formed to alternate with the rotary vane 210.

That is, it may be provided at a non-corresponding position and may be formed as a square frame through which wind can pass.

Here, since the outer blades 220 are provided in a rectangular shape, the outer blades 220 are provided with a space through which a certain amount of wind can flow, thereby making it possible to make the rotation axis 300 rotate when wind power is generated.

The first to fourth frames 221, 222, 223, and 224 may be formed of carbon fiber, vinyl, or cloth. In this case, if the first to fourth frames 221, 222, 223, and 224 are made of vinyl or cloth, The carbon fiber, the vinyl cloth and the cloth are strong against the brittle phenomenon and have excellent elasticity, so that they have good heat resistance, impact resistance and are not likely to corrode.

Also, when used in a wind turbine that is lighter than metal, there is a strong point that the outer vane 220 is easy to rotate.

In addition, the rotation of the outer wing can be much faster and can be more efficient in producing power.

In addition, vinyl or cloth can be purchased at a lower cost than metal, and it is also easy to replace, which can reduce manpower burden and reduce maintenance cost.

In general, the wing attachment method of a vertical type wind turbine via a bond or welding has a drawback in that it must be repaired as a whole when it is required to be repaired due to rust in the future.

Therefore, by using the structure of the coupling portion 240 of the present invention, the outer blades 220 can be individually repaired, which facilitates maintenance.

The coupling portion 240 may be formed of carbon fiber as in the outer blade 220.
