Description

Wind generators with variable wings that rotate horizontally with the wind {WIND POWER GENERATOR WITH THE VARIABLE BLADE TURNING HORIZONTALLY WITH THE WIND}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind power generator, and in particular, in order to obtain sufficient rotational force while rotating in the wind direction and the horizontal direction, between the fixed wing (a) and the variable wing (b) according to the direction of the wind, the rotational force of the windmill. Mechanism for driving the rotor of the windmill part (2) and the power generation part (3) consisting of a single windmill or a plurality of windmills, which are widened or reduced, and which have a plurality of variable vanes geometrically centered on a rotation axis. The generators <G> are configured to be connected so that the center of gravity is formed on the rotary shaft <sa> formed perpendicular to the ground, so that several windmills can be connected to one rotary shaft, and the center of weight is kept constant regardless of the capacity of the generator. It is possible to maintain and improve the spatial constraints of the installation site of wind power generators, which has been a problem in the prior art, and to restrict the design power generation capacity. The problem of limiting power generation is improved, and relates to a wind power generator that allows a generator to vary the amount of power according to a change in the strength of the wind.

In general, a wind turbine is installed on the hill or coast to generate electricity by using wind power. In such a wind turbine, the windmill's wings rotate in a direction perpendicular to the direction of the wind with a fixed wing, and the axis of rotation is opposite to the windmill. The power generation unit connected to the center is installed and is composed of a support perpendicular to the ground centered on the center of gravity between the power generation unit and the windmill unit. The wind power generator is provided with a windmill unit in which the power generation capacity is constant and the weight balance. The support of the wind turbine is formed at a predetermined height according to the size of the rotation radius of the blade of the windmill. Thus, the wind turbine operates normally while the wind strength is within a certain range, and the power of the designed capacity can be produced.

However, such a prior art can generate power only in a certain level when the fluctuation of the wind intensity is severely generated, and if the wind is too weak or weak, the power generation is stopped and the efficiency decreases significantly. Due to the rotor blades need to be spaced more than a certain distance from the ground, there was a problem that the space is limited to the installation site. On the other hand, when the windmill is composed of a wing that rotates horizontally with the direction of the wind is not used because it does not obtain the proper rotational force.

The present invention has been made to solve the above problems,

An object of the present invention is a variable wing <A> of a windmill unit equipped with a single windmill or several windmills on a rotating shaft of a generator installed perpendicular to the ground is installed to rotate in parallel with the direction of the wind and drive the rotor of the power generation unit By installing two generators, the wind turbine unit 2 and the generator unit 3 around the rotating shaft have a weight balance irrespective of their respective weights, and thus the power generation capacity is fixed by the weight of the windmill unit, which has been a problem in the prior art. In addition to solving the problem, the power generation can be changed and generated in conjunction with the strength of the wind pressure, and the design can be freely designed without the limiting elements required to obtain a constant torque such as the wing radius of the windmill and the separation distance from the ground. It is to provide a wind power generator which is very efficient and installable even in severe places.

Wind turbine according to the present invention for achieving the above object consists of a windmill consisting of variable wings 1, 2, 3, 4 or one or more windmills that rotate in parallel with the wind direction and vary according to the wind strength and direction A power generation unit 3 consisting of a windmill unit 2 and a rotating shaft perpendicular to the ground and one or more power generating devices for driving the rotor of the generator for generating electricity and a supporting structure formed outside the rotating shaft It is characterized in that each of the windmill part 2, the power generation unit 3, the rotation axis <sa>, the support is mechanically connected and installed so that the center of gravity is formed on the rotation axis <sa>.

It will be described below in more detail for the practice of the invention.

As described above, the wind power generator equipped with a variable wing that rotates horizontally with the wind according to the present invention stops power generation when wind pressure occurs above or below a predetermined design wind pressure, which has been a problem in the prior art, and thus the efficiency and economic efficiency of the generator. The problem of deterioration is improved, and as the wind pressure increases, the power generation amount is increased by increasing the rotational force while maintaining the rotational speed, thereby rotating the rotor of the power generation unit more. Therefore, there is an excellent effect to greatly improve the efficiency and economics of the generator.

On the other hand, the rotating wing of the windmill rotates in parallel with the ground, so that this windmill can be installed at the longest distance from the ground, and it is possible to mount several windmills on the rotating shaft so that the radius of the wing can be freely reduced while maintaining the rotational force. It is possible to greatly improve the installation site limitations of the wind turbines that have been used, so it can be installed in various places.

Hereinafter, with reference to the accompanying drawings, embodiments 2, 3 of the wind power generator of the present invention will be described in more detail.

The fixed blade (a) of the variable wing (A) remains constant regardless of the direction and strength of the wind, but the variable blade (b) is located at the balance point between the weight of the variable blade itself and the force of the spring (d). When it blows inward as in 2, it expands from the position of the variable wing (b) to the position of the variable wing (b ') in proportion to the wind strength, (wind strength) + (variable wing weight) = (tension of the spring). At this balanced position, the rotational force F1 acts in the rotational direction of (e). On the other hand, the fixed wing (a) of the variable wing (C) located on the opposite side of the variable wing (A) around the axis of rotation (sa) maintains a constant shape regardless of the direction and strength of the wind, but the variable wing (b) is the variable wing itself. When the position of the balance between the weight of the spring and the force of the spring (d) and the wind blows out as shown in Figure 3 and narrowed from the position of the variable blade (b) to the position of the variable blade (b ') in proportion to the strength of the wind At the position where (variable blade weight) = (tension force of the spring) + (wind strength) is in equilibrium, rotational force F2 acts in the opposite direction of rotation of (e). Therefore, the rotational force F of the windmill is generated by the difference between the rotational force F1 and the rotational force F2. This rotational force F fluctuates in proportion to the wind strength.

On the other hand, if the rotational force is generated at a certain level while driving the initial generator <A> with this rotational force (F), it is possible to continuously operate the generator <B>, the generator <C>, in order to be proportional to the rotational speed of the shaft. By installing the control unit in the power generation unit, the amount of power generation increases in proportion to the wind strength. However, in the case of a strong wind, such as a typhoon, even if all of the power generation equipment can be a case that the rotation axis exceeds a certain number of revolutions. In this case, the windmill uses the centrifugal force generated in proportion to the rotational speed in the variable vanes, and the hydraulic latch (c) acting hydraulically reduces the limit of the gap between the fixed blade (a) and the variable blade (b) to reduce the rotational force F1. It is designed not to exceed the rotation speed of more than a certain level.

Here, the terms or words used in the present specification and claims should not be construed as being limited to ordinary or dictionary meanings, but should be construed as meanings and concepts corresponding to the technical spirit of the present invention.
