Description

[0001] The present invention relates to a horizontal rotation blade for wind turbines,

The present invention relates to a horizontal rotary blade for a wind turbine generator, more particularly, to collecting the amount of wind contact with a blade to concentrate the largest moment to a position where the moment is greatest, So that the power can be stably and efficiently generated even in low winds.

In recent years, in order to protect the global environment, power generation facilities using clean energy sources such as solar power, tidal power, and wind power that can replace conventional fossil fuels have become more important.

Wind power generation using dual wind power is a power generation facility that generates electric energy by driving the generator by the rotational force of the rotating blades rotated by the wind.

Generally, a wind turbine is composed of three parts: a rotary wing, a transmission, and a generator. The rotary wing is rotated by the wind to convert wind energy into mechanical energy. The transmission changes the rotational force The generator transmits the rotational speed of the rotating blades to the generator by increasing the rotational speed of the rotating blades to a required rotational speed of the generator. The generator serves to convert the mechanical energy generated from the rotating blades into electrical energy.

Such a wind turbine generator is mainly constructed such that the direction of the rotation axis of the blade is horizontally arranged with respect to the ground, and the blade is rotated in a direction perpendicular to the ground.

Patent Document: Domestic Publication No. 10-2001-0093793 (Published Date October 29, 2001)

However, a wind turbine having a blade rotating perpendicularly to the ground requires a high level of technology and equipment to be installed in order to maintain a sufficient distance from the ground.

In addition, the direction of the wind is greatly affected.

Generally, a wind turbine generator is an apparatus that generates electric energy by rotating a rotary blades by wind, so it is important to optimize the resistance of the rotary blades to wind.

Conventionally known rotary blades have been mainly applied with a structure in which they are twisted in a certain direction similar to a blade structure of an electric fan or a helicopter.

However, since several blades are provided in the same structure and are twisted in the same direction, there is a disadvantage in that the rotational force by the wind is maximized and the rotational resistance of the rotating blades is not minimized.

Therefore, the rotary blades are generally not optimized according to the direction and intensity of the wind.

In addition, when the wind intensity is higher than a predetermined speed, since the rotary blade rotates, there is a problem that when the wind intensity is weak, the rotary blade does not rotate and is inefficient in terms of energy production.

An object of the present invention is to provide a wind power generator capable of efficiently producing an energy despite a small amount of wind by directing the amount of wind to be contacted with a blade in a direction corresponding to the direction and intensity of the wind, And to provide a horizontal rotary blade for use.

It is another object of the present invention to provide a horizontal rotary blade for a wind turbine generator which is installed at a low cost and which can be easily installed in a home or a building by installing wings to rotate horizontally with respect to the ground.

It is a further object of the present invention to provide a wind turbine blade for a wind turbine that is highly efficient by reducing the wind resistance, To provide a rotating wing.

In order to achieve the above object, the present invention provides a blade (10) that is rotated by a wind force to operate a generator (2) while being attached to a rod (1)

The blade (10) has an acute angle blade (20) having a sharp edge portion (21) formed along the longitudinal direction on the back surface of the blade portion (a) so as to be inclined gradually from front to back,

A resistance blade 30 is provided so as to have a slanting angle portion b larger in angle than the protrusion portion a in a state in which the induction hole 22 is projected toward the opposite end of the rotation center in front of the acute angle blade 20, . ≪ / RTI >

According to the present invention, the amount of wind contact with the resistance blade 30 is guided to the position of the induction hole 22 at the end where the moment is most applied, thereby enabling efficient energy production in spite of a small amount of wind It will be done.

In addition, by installing the wings so as to rotate horizontally with the ground, it is easy to install, low installation cost, and can be easily installed in a home or a building to be used as a private generator.

The resistance blade 30, which is in contact with the wind direction to resist the wind, increases the rotational force by applying a large resistance, and the acute angle blade 20 which is rotated in the opposite direction greatly improves the efficiency by reducing the wind resistance There is a number.

1 is a perspective view showing the installation state of the present invention.
2 is a plan view
3 is a front view of the installation state of the present invention.
Fig. 4 is a front view showing only enlarged wings of the present invention. Fig.
5 is a longitudinal sectional view showing the blade of the present invention cut.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in the drawing, the wind turbine generator of the present invention is constructed such that the rods 1 attached with the vanes 10 are equidistantly mounted and rotated by the wind power to obtain electricity from the generator 2, The wings 10 are installed such that the direction of rotation is horizontal to the ground but relatively close to the ground.

At this time, the rotation of the rods 1 is not directly transmitted to the rotation axis of the generator 2, but the pinion 4, which is engaged with the gear 3 via the comparatively large gear 3 as shown in Figs. 2 and 3, It is preferable to increase the number of revolutions thereof so as to be able to operate the rotary shaft of the compressor.

The blade 10 has an acute angle blade 20 having a sharp edge portion 21 formed along the lengthwise direction of the blade 10 and having an inclined edge portion gradually inclined from front to back,

A resistance blade 30 is provided so as to have a slanting angle portion b larger in angle than the protrusion portion a in a state in which the induction hole 22 is protruded toward the opposite end of the rotation center in front of the acute angle blade 20, .

The material of the blade 10 is made of a synthetic fiber such as FRP or Tetron which is excellent in strength and toughness and is sufficiently resistant to wind to increase the rotational force against the rotating blades.

When the wind is blown in a specific direction, the wing 10 of the present invention having such a structure is installed mainly at a portion of the resistance blade 30 and the acute angle blade 20 That is, in the position of the induction hole 22.

At this time, most of the force of the wind is applied to the induction hole 22, which is located at a position farthest from the rotary shaft 5 after being acted on the slanting portion b, .

Therefore, after a part of the rotational force is generated in the resistance blade 30, the force of the wind is concentrated in the induction hole 22 at the position having the greatest moment again. As a result, It is possible to operate it largely.

Since the acute angle blade 20 located at the rear of the blade 10 has a sharp blade 21 at its end by the angular portion a, the blade 10 is rotated in the direction in which the wind is applied The contact resistance is greatly reduced.

Therefore, the efficiency of electric energy can be greatly improved even with a relatively small wind strength.

This feature makes it possible to generate electric energy by installing individual power generation devices on the rooftops of buildings or rooftops of ordinary homes without the necessity of confining power generators to specific locations such as high seas and high mountains, It can be profitable.

The foregoing description is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention.

Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments.

It is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
