Description

In general, power generation that produces electricity includes thermal power generation, hydropower generation, nuclear power generation, solar power generation, and wind power generation. In the construction of a power plant for thermal or nuclear power generation, it is not only difficult to secure the site, but also difficult to preserve the surrounding environment and to treat waste. In addition, since the hydroelectric power generation is limited, it is difficult to continue power generation, so it is difficult to secure the power generation quantity.

In addition, the device for wind power generation is generally composed of a generator having a plurality of blades installed at the upper end of the installation column fixedly installed at a height of 5m or more, and generating electricity according to the rotation of the propeller. In such a wind power generator, since the propeller rotates only when the wind is maintained at a constant speed or higher and the air density is high, there is a problem that efficient power generation cannot be achieved when a breeze blows or the direction of the wind is not constant.

Accordingly, the applicant of the present invention is proposing a new type of wind power generation device capable of generating power even when a breeze blows or the direction of the wind is not constant, and is improving the power generation device so that more stable and efficient power generation can be achieved. .
