The present invention relates to an apparatus for amplifying rotating force of a wind power generator, and more particularly, to an apparatus for amplifying rotating force of a wind power generator, which doubles the rotating speed of a blade by ascending air current and rotational inertia, thus enhancing power generating efficiency and simultaneously facilitating the continuous rotation of the blade even when the blade rotates at low speed due to a lack of wind power.
In general, a typical power generating method for producing electricity may include thermal power generation in which mechanical energy generated by the combustion of fossil fuel is converted into electric energy, thus producing electric power, and nuclear power generation in which water is heated using energy generated by fission chain reaction to produce vapor and then a turbine of a generator is rotated by the vapor, thus producing electric power. However, such a power generating method is problematic in that huge construction cost is required to build power generating facilities, a quantity of harmful substances, such as radiation, radioactive waste or exhaust gas that are harmful for environment and human bodies in a power generating process, may be discharged, and serious environmental destruction may be caused when an accident occurs in power generating facilities. Thus, research into the power generating method of utilizing natural energy, such as wind power, tidal power, water power or solar heat, as an energy source is actively conducted, because the natural energy does not cause pollution unlike thermal power- or nuclear power-generation and there is no possibility that the natural energy is depleted. Here, wind power generation in which wind power energy is converted into electric energy using a blade that may be rotated by wind, thus producing electric power is simple in structure or installation of power generating facilities and is easy to operate and manage the power generating facilities due to unmanned or automatic operation. For this reason, recently, the adoption of the wind power generation is rapidly increased.
For example, a wind power generator has been proposed in Korean Appl. No. 10-2008-0083107. According to the cited document, a blade rotated by wind power is fastened via a spoke to an outer surface of a rotor that is inserted into a rotating shaft. Thus, even when the blade is rotated at low speed because the wind power acting on the blade is insufficient, the wind power generator may generate electromotive force by electromagnetic induction action between the rotor and a stator.
However, the above-described invention is configured such that the rotor and the stator that may generate electromotive force by electromagnetic induction action between them are opened to an outside. Thus, this is problematic in that power generating equipment may be damaged by external force acting on the power generating equipment or by water that may penetrate into the power generating equipment in the case of rain during a power generating process, and it is impossible to produce electricity of constant output when uniform wind power does not act on the blade fastened to the outer surface of the rotor, so that the wind power should be converted into constant output using a separate electric power converter.
In order to solve the problems, the present invention is intended to provide an apparatus for amplifying rotating force of a wind power generator, in which an upper horizontal rotating unit and a lower horizontal rotating unit that are inserted into the same rotating shaft as a blade rotatable by wind power and are provided under the blade are rotated by the rotation of the blade, so that the rotating speed of the blade is increased by ascending air current produced in the upper horizontal rotating unit and rotational inertia increased by the lower horizontal rotating unit, thus allowing the wind power generator to efficiently generate power, and magnetic members are inserted into ends of the upper horizontal rotating unit and a vertical rotating unit that is rotatable by the rotation of the upper horizontal rotating unit such that the same poles are opposite to each other, so that the blade is continuously rotated by repulsive force between the magnetic members even when the blade rotates at low speed due to a lack of wind power acting on the blade, thus facilitating continuous power generation, and simultaneously the rotating speed of the blade may be doubled when the blade rotates at high speed.
Accordingly, the present invention has been made keeping in mind the above problems occurring in the related art, and an aspect of the present invention is directed to an apparatus for amplifying rotating force of a wind power generator, in which an upper horizontal rotating unit capable of generating ascending air current as the upper horizontal rotating unit is rotated by the rotation of a blade by wind power and a lower horizontal rotating unit capable of increasing rotational inertia may be inserted into the same rotating shaft as the blade, the blade may be continuously rotated even when the blade rotates at low speed due to a lack of wind power acting on the blade, and simultaneously the rotating speed of the blade may be doubled when the blade rotates at high speed.
In order to accomplish the object, the present invention provides an apparatus for amplifying rotating force of a wind power generator, including a central rotating shaft provided to pass through a multilayered rack-like frame unit to be rotated by wind power; a blade coupled to an uppermost end of the central rotating shaft; and upper and lower horizontal rotating units fastened to upper and lower fastening plates that are installed about the central rotating shaft to produce ascending air current or increase rotational inertia, by spreading the horizontal rotating units upwards or downwards when the blade is rotated.
Further, the present invention provides an apparatus for amplifying rotating force of a wind power generator, including a vertical rotating unit rotated vertically in conjunction with a central rotating shaft so as to increase rotating force of an upper horizontal rotating unit; a vertical rotating unit coupled via a horizontal rotating shaft to continuously rotate the upper horizontal rotating unit by repulsive force between magnetic members fastened to a side of a vertical wing of the vertical rotating unit and simultaneously double rotating speed of the upper horizontal rotating unit; and a bearing provided to smoothly rotate the central rotating shaft and the horizontal rotating shaft by wind power acting on the blade.
