The cross section of the flexible rotary blade of the wind power generator is formed in a streamlined shape.

The flexible rotary vane, the variable plate, the flexible rotary vane and the rotary column of the wind power generator are hinged to each other by a hinge member.

The wind turbine further includes a reinforcing plate coupled to both ends of the flexible rotary blades to maintain the shape of the flexible rotary blades.

The wind power generator further includes a hook formed on one of the reinforcing plate and the rotating pillar, and a hook formed on the other one of the reinforcing plate and the rotating pillar and hooked to the loop.

The wind power generator includes a fixing member formed on one of the rotating column and the reinforcing plate, and a locking member formed on the other one of the rotating column and the reinforcing plate and hooked to the loop.

According to the wind turbine generator of the present invention, when the wind generator is operated without blowing wind, or when the wind generator is not operated, or when the wind generator is being operated, the flexible rotary blades are not bent, Thereby making it easy to move and store and also to set the curvature of the flexible rotary blade accurately to a desired shape, thereby improving the power generation efficiency.

A support unit 600 is disposed below the generator 100, and the support unit 600 serves to fix the generator to the ground. The supporting unit 600 and the generator 100 have a structure that can be mutually coupled or separated.

The rotating column 200 is formed in a columnar shape or a rod shape and the axial direction of the rotating column 200 and the axial direction of the rotating shaft 110 are arranged parallel to each other. Accordingly, electricity is produced from the generator 100 while the rotating shaft 110 is rotated by the rotation of the rotating pillar 200.

In one embodiment of the present invention, the rotating pillar 200 may be formed in a cylindrical shape, a square pillar shape, or a polygonal pillar shape.

The rotating pillar 200 may be formed in an empty shape or an interior filled shape, and the rotating pillar 200 may be formed of metal or synthetic resin.

The variable plate 300 is formed in the shape of a plate having an opening at its center, and the variable plate 300 is inserted into the outer peripheral surface of the rotating column 200. The variable plate 300 has a structure that is raised or lowered along the outer peripheral surface of the rotating column 200.

The flexible rotary vane 400 has a shape similar to a rectangular parallelepiped plate, and the cross section of the flexible rotary vane 400 is formed into a streamlined shape similar to an airplane wing.

In one embodiment of the present invention, a plurality of flexible rotary blades 400 are coupled to the rotating columns 200 and the variable plate 300.

One end of each flexible rotation blade 400 is fixed to the variable plate 300 and the other end opposite to the one end of the flexible rotation blade 400 is fixed to the upper end of the rotation column 200.

In one embodiment of the present invention, the one end of the flexible rotary vane 400 is hinged to the variable plate 300, and the other end opposite to the one end of the flexible rotary vane 400 is connected to the rotary pillar 200 .

When the one end of the flexible rotary vane 400 is hinged to the variable plate 300 and the other end of the flexible rotary vane 400 is coupled to the rotary pillar 200, The blades 400 are not bent but are formed in a shape parallel to the side surface of the rotating pillar 200 or by moving the variable plate 300 in a direction parallel to the axial direction of the rotating pillar 200, And has a curved shape in a curved shape.

When the flexible rotary vane 400 is curved upward by downwardly moving the variable plate 300 in a state where the flexible rotary vane 400 is hinged to the rotary column 200 and the variable plate 300, The power generation efficiency of the wind turbine generator 700 is greatly changed depending on the curvature and shape of the flexible rotary blade 400. [

Also, since the curvature of the flexible rotary vane 400 should be always constant when the flexible rotary vane 400 is repeatedly bent in the curved shape by up-down the variable plate 300, The reinforcing plate 450 is disposed on the flexible rotary vane 400 as shown in FIG.

The reinforcing plate 450 may be disposed on the inner surface of the flexible rotary blade 400 facing the rotary column 200, for example, among the flexible rotary blades 400.

Specifically, the reinforcing plate 450 is disposed at the end of the flexible rotary blade 400 adjacent to the variable plate 300 and at the end adjacent to the rotary column 200, respectively.

The reinforcing plate 450 is formed, for example, in a plate shape, and the reinforcing plate 450 is made of a material having a higher strength than the flexible rotating blades 400. When the flexible rotary blade 400 is formed of a synthetic resin material, the reinforcing plate 450 may use a metal plate having a higher strength than the synthetic resin.

In addition, the reinforcing plate 450 may be formed in a shape that is in close contact with the surface of the flexible rotary vane 400.

The fixing member 500 may have various configurations for fixing the variable plate 300 to the pillar 200. In one embodiment of the present invention, the fixing member 500 includes a ring 510 and an engagement member 520 ).

The ring 510 may be formed, for example, in a reinforcing plate 450 facing the pillar 200. The ring 510 may be coupled to the reinforcing plate 450 by welding or the like.

The engaging member 520 is coupled to the rotating column 200 and the end of the engaging member 520 is bent in a rounded state and the bent portion is caught by the loop 510. [

As the latching member 520 is coupled to the loop 510, the variable plate 300 is fixed at a designated position of the pillar 200 so that the flexible rotary blade 400 can generate electricity with maximum efficiency by the wind And is bent in a shape suitable for the following.
