Description

Wind turbine of wind turbine with variable wings {THE VARIABLE BLADE OF THE WIND POWER GENERATOR}

The present invention relates to a windmill of a wind turbine, and in particular, in order to obtain a sufficient rotational force to rotate in the horizontal direction and the wind direction of the variable wing <A> according to the direction of the wind (a) and the lower variable (b) The windmill part (2) consisting of one or a number of windmills, which are widened or reduced to improve the rotational force of the windmill, and whose number of variable wings are geometrically centered on the axis of rotation, is formed perpendicular to the ground. The center of gravity is installed on the rotating shaft so that several windmills can be connected to one rotating shaft and the center of weight is kept constant regardless of the capacity of the generator. In addition to improving the restriction, the problem of limiting the development of the place where the strong change in the wind is severely improved, which is proportional to the change in the strength of the wind. Relates to a windmill for wind power generation apparatus according to obtain the rotational force to vary the power generation by the generator.

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 installed so that one windmill or several windmills are rotated in parallel with the direction of the wind on the rotary shaft of the generator installed perpendicular to the ground and the weight balance is independent of the weight of each of the windmill unit 2 around the rotary shaft The variable wing (A) consisting of the variable wing (a) and the variable wing (b) of the windmill part is changed according to the direction and intensity of the wind, and when the rotational force exceeds a certain standard, the centrifugal force is used. It is driven and consists of a windmill part equipped with a hydraulic latching device (C) that limits the variation of the variable blades. It generates electricity by varying the amount of electricity generated, and it is necessary to obtain a constant rotational force such as the wing radius of the windmill and the separation distance from the ground. Free design is possible, efficiency is very good in places with severe spatial restrictions, without limiting factor of the body is a wind turbine generator that can be installed to provide.

Windmill of the wind power generator according to the present invention for achieving the above object rotates in parallel with the direction of the wind and the variable wing (a) and the variable wing (b) consisting of up and down or left and right have a width depending on the strength and direction of the wind Windmills consisting of variable variable vanes 1, 2, 3 and 4, with a mechanical device for limiting the width of the variable vanes by using centrifugal force of the blades when excessive rotational forces occur, or a windmill unit consisting of one or more windmills (2 Each windmill is mechanically connected to the rotating shaft <sa> so that the center of gravity is formed around the rotating shaft <sa> which is perpendicular to the ground.

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 it is possible to install several windmills on one rotating shaft to obtain various rotational strengths, and to design a generator whose power generation can be changed according to the characteristics of the user. have.

On the other hand, it is possible to install several windmills on one rotating shaft to freely reduce the radius of the wing while maintaining the rotational force, thereby greatly improving the installation site limitation of the wind power generator, which has been a problem in the prior art. It is possible.

Hereinafter, with reference to the accompanying drawings, embodiments 2, 3 of the windmill of the wind power generator of the present invention will be described in more detail. It is possible to have a variable wing that fluctuates vertically or horizontally, but here it is explained based on a variable wing that fluctuates vertically.

The upper variable blade (a) and the lower variable blade (b) of the variable blade (A) are supported by the support (g) for supporting the variable blade (A) and the hydraulic latch (c) for limiting the opening and closing allowable width of the variable blade (A). And the spring (d) maintains a constant shape. The variable blade (a) and the variable blade (b) are positioned at the balance point of the weight of the variable blade itself and the force of the spring (d), and the wind blows inward as shown in FIG. In proportion to the strength of the wind, the position of the variable wing (a) is changed from the position of the variable wing (a ') to the position of the variable wing (b') at the position of the variable wing (b), and the spring (d) The rotational force F1 acts in the rotational direction of (e) at the position where (wind's strength) + (variable blade weight) = (tension force of the spring) is balanced by spring (d '). On the other hand, the upper variable blade (a) and the lower variable blade (b) of the variable blade <C> located on the opposite side of the variable blade <A> around the axis of rotation <sa> and the support (g) for supporting the variable blade <C> and It maintains a constant shape by the hydraulic latch (c) and the spring (d) limiting the allowable opening and closing width of the variable wing <C> and the variable wing (a) and variable wing (b) is the weight of the variable wing itself and the spring (d) When the wind is blown out as shown in Fig. 3, when the wind blows out as shown in Fig. 3, the position of the variable blade a is changed from the position of the variable blade a to the position of the variable blade b in proportion to the wind intensity. At the variable wing (b ') and the spring (d) as the spring (d') (variable wing weight) = (spring tension) + (wind strength) at the equilibrium position (e The rotational force F2 acts in the opposite direction of rotation. 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, the rotational force (F) is used as the power generator of the generator. In the case of installing several windmills on one rotating shaft, it is possible to increase or decrease the rotational force in proportion to the wind strength by installing the windmill number controller that senses and drives the wind strength and speed. However, in the case of a strong wind, such as a typhoon, even if all the power generators are operated at the maximum power generation, the rotation shaft may exceed a certain number of revolutions. In this case, by using the centrifugal force generated in proportion to the rotational speed in the variable vanes and hydraulically actuated hydraulic latch (c) reduces the limit of the gap between the variable blade (a) and the variable blade (b) by reducing the rotational force F1 It is designed not to exceed the rotational speed of the windmill above a certain level.
