A wind turbine generator is composed of rotating blades that are rotated by wind introduced from the outside, a rotating shaft that transmits rotational force of the rotating blades, a power transmission unit that is driven by the rotating shaft to transmit power, and a generator that generates electricity.

The wind turbine generator is divided into a horizontal type and a vertical type according to the arrangement direction of the rotation shaft described above.

However, as the conventional wind power generator is designed so that the turbine is exposed to the outside space and is affected by wind from all directions, in areas where the wind direction changes frequently or the wind speed is slow, the wind is dispersed around the turbine and the wind blows toward the front of the turbine. This is not accurately transmitted, and accordingly, the turbine is not sufficiently rotated, so that continuous and stable power generation is difficult.

In addition, as the conventional wind power generator has a structure that is matched 1:1 with the generator, in order to increase the amount of power generation, the overall size of the wind power generator must be increased or a plurality of wind power generators must be installed on the ground, thereby As a result, a lot of cost is required, and there is a very inefficient problem in space utilization.

In addition, in the conventional wind turbine generator, as wind turbulence flows into the turbine, air resistance is generated in the reverse direction during rotation, and as a result, there is a difficulty in reducing power generation efficiency.

In addition, conventional wind power generators are damaged by external environments such as temperature, humidity, sand, foreign matter, algae, etc., or noise generated during operation, as the turbine is disposed in a state exposed to the external space. There were problems with installation.
