[Industrial applications]

  The present invention relates to a power generation wind turbine, and in particular, its impeller automatically changes to a direction opposite to the wind direction. It is related to a power generation wind turbine that is capable of generating electricity by being positioned correctly in the headwind.

[0002]

[Prior art]

  We were hit by two oil shocks in 1973, caused environmental damage and After being taught by a sense of crisis such as depletion of energy, wind power was generated as clean energy. The applied research of electric power came into the spotlight again, and now, over the past 10 years, The total amount of power generated by wind turbines in the world has reached a considerable amount, It is said that it is comparable to the amount of power generated by a certain place, and it has the characteristic that it does not cause pollution. So, while the attention of the people around the environment is gathering attention, future development will be noted.

[0003]   Especially, for example, in an island country with a lot of seasonal winds such as Taiwan, its coastal area and mountainous area The annual average wind speed is as high as 5.5 m / sec, and there is a lot of wind energy. Very suitable for applied research on wind power. However, since ancient times, the wind has been Vehicles are installed in a nearly fixed orientation, ie the most statistically high year of installation in the area This is because the blades of the windmill are mounted accurately in the almost opposite wind direction relative to the wind direction. Even if a strong wind with a different wind direction blows against the fixed headwind direction, the windmill's wings The roots remain stationary or cannot rotate at full wind speed.

[0004]

[Problems to be solved by the device]

  In view of the above problems of the conventional power generation wind turbine, the present invention makes the wind turbine itself depending on the wind direction.
