On the other hand, apart from the air volume control gate 130 connection structure, the support structure of the air volume control blade 120 may be fastened from the rear. In this case, there is an advantage that the air volume control surface increases.

That is, the usual air volume control blade 120 has a function of concentrating the wind to the multi-stage vertical blades 200 in the left and right by the inclined structure on both the left and right sides. In addition, the air volume control vane 120 also performs a rudder function for rotating the wind turbine in the left-right direction with respect to the direction control main shaft 140 described later.

On the other hand, as the amount of wind or wind pressure increases, as the degree of rotation to the rear increases, the concentration of the wind is lowered above a certain angle to reduce the amount of wind. In addition, as the air volume or wind pressure increases, the air volume control blade 120 adjusts the amount of wind entering the multi-stage vertical blades 200 by moving the air volume control gate 130 in the direction of the multi-stage vertical blades 200.

Providing high quality electrical energy with little variation in power generation can be generated. In addition, the rearward rotation is prevented from damage of the air volume control blade 120 itself due to strong winds.

In addition, the direction control main shaft 140 is extended from the ground and the blade rotation axis 300 and the center thereof is the same and fastened to the body portion 100 to correspond to the direction of the wind to the body portion 100 It is installed rotatably. That is, the direction control main shaft 140, the front surface of the multi-stage vertical blades 200 serves to rotate so as to face in the wind blowing direction.

In addition, at the rear end of the body portion 100, a rudder (not shown) may be further configured. That is, the rudder (not shown) is provided in the discharge port formed on the rear side of the body portion 100 so that the front of the multi-stage vertical blades 200 around the direction control main shaft 140 blows wind in response to the wind direction. It rotates to face in the direction of coming.

Accordingly, the wind power generator according to the present invention can freely adaptively drive corresponding to the entry wind direction.
