Abstract

The present invention relates to a wind power generation system for generating electricity by using two impellers, wherein two impellers arranged side by side and adjacent to each other are influenced by winds of a predetermined intensity and are rotated away from each other to the left and right to be concealed behind the induction plate. By repeating the operation of returning to the original position by the means, the fatigue of the struts and the guides supporting the two impellers is reduced and prevented from being damaged,
In addition, the present invention relates to an impeller left and right displacement type wind turbine system in which two impellers disposed adjacent to each other are allowed to always face the wind direction depending on the wind direction, thereby enhancing power generation efficiency.

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 .

According to an aspect of the present invention, there is provided an impeller left and right displacement wind turbine system,

First and second impellers arranged side by side adjacent to each other and having rollers at respective upper and lower ends thereof;

First and second guides disposed on upper and lower portions of the impellers, respectively;

Shoring is installed each said guide; And

, &Lt; / RTI >

Each guide is characterized in that the rails are coupled to each of the rollers has a track that can be moved so that the impellers arranged side by side adjacent to each other left and right by a wind of a predetermined intensity or more.

And it is characterized in that it further comprises a return means for returning each of the impellers left and right away from the wind of a certain intensity or less to the original position along the rail.

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.

In the meantime, the strut is provided with an induction plate for guiding the inflow air into the inner ends of the impellers disposed adjacent to the right and left adjacently and for concealing the left and right impellers.

In the impeller left-right displacement type wind power generation system according to the present invention,

When two or more impellers are moved horizontally, the two impellers are shifted to the left and the left to be hidden behind the induction plate. When the impellers of two impellers decrease their rotational force, they move to return to the original position. There is a great effect that the damage rate can be minimized by reducing the fatigue of the structure of the guide or the support structure.
