In the prior art, a housing is formed in which a wind can be easily moved with a predetermined space, and a wind-driven driving fan is installed at the opposite side of the housing, A connection rotary bar is provided to be rotated by the rotation of the driving fan, and a generator for converting electric energy into electric power by rotation is provided at one end of the connection rotation bar,

It is possible to increase the rotational force of the driving fan compared to the intensity of the wind (wind speed) of the inhaled air, thereby improving the electric power generation amount, enabling electric power generation in an area where the wind is little, This is a technology for providing a power generation device using wind power capable of rotating a fan to produce desired electricity.

However, in the above-mentioned prior art, there is a problem in that when strong winds are applied to two driving fans disposed side by side, the supporting member, which is supported by the housing or the ground, may be bent or broken.

Particularly, when the two drive fans are disposed at positions deviated from the center of the support, and the structure of the housing and the drive fan are arranged eccentrically from the support, there is a problem that the support may be damaged due to strong wind.

In the present invention, when two or more impellers are horizontally disposed adjacent to each other when the wind is influenced by a wind of a predetermined intensity or more, the impeller is moved away from the left and right so as to be hidden behind the induction plate. The present invention provides an impeller left and right displacement type wind turbine system capable of reducing the fatigue and minimizing the damage rate.

Another object of the present invention is to provide an impeller left and right displacement type wind turbine system in which two concealed impellers can be operated in the original position by return means, that is, repeatedly operated in accordance with the intensity of wind .

And a returning means for returning the impeller moved to the left and right to the original position along the rail when the impellers are influenced by a wind of a predetermined intensity or less.

At this time,

And the first and second weights are suspended from the lower ends of the rotating shafts of the respective impellers through wires and embedded in the struts.
