Description

Blade for wind power generator {a blade for wind power generator}

The present invention relates to a wind turbine blade, and more particularly, the wind blowing forward in the direction of rotation of the rotating body is coupled to the blade enters the suction port is configured to be coupled to the front of the blade, the wind entering the suction port is It is combined with the suction port and enters a space that can receive air therein, and the wind entering the space strikes the inside of the edges of the rear and side surfaces which are combined with the space to obtain the effect of the rotating body obtaining rotational force. And, the wind blowing forward in the opposite direction of rotation of the rotating body that is coupled to the wing is made of a streamlined back side of the wing has the effect of reducing the resistance of the air on the back of the wing and the wind blowing from the front, Since the side of the wing is also streamlined, the back of the wing Likewise, the effect of reducing the resistance of the wind blowing from the front to increase the rotational force of the rotating body, the disk wing is configured vertically by one or more by combining with one or more shafts by the side surface of the lower portion perpendicular to the back of the wing The present invention relates to a wind turbine blade, which is characterized in that it is possible to obtain an effect of efficiently utilizing the wind speed according to the "altitude change table of the wind direction" without being made into a plane.

In general, a wind turbine generates electric energy by generating a generator coupled to a rotor by obtaining a rotational force by using a wind in which a rotor composed of at least one wing is coupled to the rotor. Particularly, in a wind turbine having a vertical shaft, the rotor is configured. The front of the wing is pushed backward by the wind blowing from the front, giving the rotational force of the rotor, while the back of the wing is rotated due to the resistance of the air on the back of the wing and the wind blowing from the front as the rotor rotates. There was a problem that was inhibited.

In recognition of this problem, in order to reduce the resistance of the air on the back of the wing and the wind blowing from the front as the rotor rotates, the "U" shaped wing with the low air resistance coefficient, the "S shaped wing, angle" The rotors have been developed by combining various types of wings such as quasi-wings and angled wings. However, when the wings are combined with the vertical axis wind turbine, the resistance on the back of the wing can be reduced, but Since the side surface of the wing that is vertically coupled consists of a plane, the resistance of the wind blowing from the front while the rotor rotates is greater than the resistance of the back of the wing.

In addition, the back of the wing is a medium- and large-sized vertical axis using a rotating body that combines a variety of wings such as "U" shaped wings, "S" shaped wings, angled wings, angled wings, etc. In order to develop a wind power generator, the cross section of the wing becomes wider, and the side surface of the lower portion perpendicular to the back of the wing becomes wider in plane, so that the rotor is blown from the air and the front blows when the rotor rotates. There is a problem that the rotor does not obtain the rotational force at low wind speed because the wind resistance increases.

Therefore, the present invention forms a front surface configured by the combination of the absorber that can enter the wind to obtain a rotational force by the front wind blowing in the rotational direction of the combined rotor blades, the space that can accommodate the wind entering the absorber Forming, and the wind enters the space to hit the rim inside the space so that the rotor can obtain a rotational force, the rotor body combined with the wing by the wind blowing in the opposite direction of rotation by the wing back and side In order to reduce the resistance of the wing and the side and the side is formed in a streamlined upper / lower housing without forming a plane, and by forming a border coupled to the streamlined upper / lower housing to form a rotor when rotating The rotor is rotated by the wind blowing in front of the back and side of the wing In order to rotate, the resistance coefficient is further lowered, and when the wing is coupled to a small wind power generator, such as when the wing is coupled to a small wind power generator, the cross section of the wing and the back of the wing such as a small wind power generator are increased even though the wing cross section is widened. It is an object of the present invention to provide a wing for a wind turbine so that the side is not made like a plane.

The configuration of the present invention provides a wind turbine blade, characterized in that the front side is formed of one or more streamlined disc blades cut in combination, the disc blades are composed of one or more shafts.

In addition, the disc wing forms a streamlined upper / lower housing in which the front face is cut, and is configured to be coupled to the upper / lower housing to form an intake port in the cut face to suck outside air, and is coupled to the suction port. It is configured to form a space to accommodate the air therein, and is configured to combine with the space to form one or more outlets through which the internal air can escape, form one or more frames configured to be combined with the outlet, Forming the inner edge of the back and side so as to be struck while the air inside the frame is combined with the frame, characterized in that the inside and the outside of the frame is configured to combine.

In addition, the border is formed in a curved shape or an angled form or a flat shape inside the border, characterized in that the outer frame is formed of a combination of a curved shape or an angled form or a date.

In addition, when the disk blade is configured to combine more than one, characterized in that the front surface is made as a corrugated tube shape cut.

In addition, the blade is characterized in that the coupling is made of a vertical axis wind turbine generator.

By combining the wind turbine blade of the present invention with a vertical shaft-type wind turbine, the wind blown from the front by the suction port formed on the front of the blade enters the inner space of the blade to push the blade back to obtain a rotating force It works.

In addition, the blade is composed of a streamlined disk blade, the wind blowing in the opposite direction in which the rotor rotates and the air on the back of the blade hit the edge of the disk blade air and wind of the streamlined upper / lower housing The effect of being dispersed in up, down, left and right, the effect of lowering the resistance of the back and side of the disc blade and the medium-large wind power generators, such as a small wind power generator, it is possible to obtain the effect that the rotor can obtain the rotational force at low wind speed.
