Description

GENERATOR OF EOLIC ENERGY FOR AN URBAN AREA TECHNICAL FIELD The present invention relates to a wind power generator that can be installed in an urban area, and more particularly, to a wind power generator that can be installed in an urban area that can supply electricity that is consumed in a building of a urban area, making it possible to carry out the generation of electrical energy by installation in the urban area where there is not much wind.

BACKGROUND OF THE INVENTION A general method of generating energy includes generating hydroelectric energy using water energy, generating thermal energy using fossil fuel, and generating nuclear energy using nuclear energy.

Such generation methods require large-scale generation equipment and a large amount of energy source to operate the generation equipment, and there is a restriction at one installation site thereof. Particularly, because the fossil fuel of petroleum or mineral coal as a source of energy that is used for the generation of thermal energy has great dependence, compared to other fuel, there is a problem of depletion of resources. In addition, there is a problem in that generation methods are not environmentally friendly methods due to air pollution and the flow of radioactivity and resources to generate energy are limited, and thus there is a limitation that the use of Generation methods is not permanent.

Therefore, in order to prevent the depletion of resources according to the use of oil or coal and environmental pollution due to the appearance of various pollutants and various calamities according to the global warming that occurs due to the combustion of oil or mineral coal today, a method of generating energy that can use an environmentally friendly and permanent source of energy, using the natural energy of a solar heat, tidal energy, wave energy, wind energy, and energy from the water, has been developed and applied.

A method of generating energy from a method of converting solar energy or wind energy into electrical energy, and storing electrical energy in an energy storage battery, receives considerable restriction of the climate and the environment. Because the generation of tidal energy can obtain electrical energy when a tidal power generator is installed in an area in which a waning difference and the tidal flow is large, the generation of energy from the tides tides can only be applied to a locally limited site, and a wave energy generator can also be installed only at a limited site in which the waves occur continuously as the generation of tidal energy, and thus there is a defect in which there is a restriction on an installation site.

The generation of wind energy mainly uses a method of generating energy by rotating a wind blade using strong wind by installing a wind power generator on a hill or in a field where there is a lot of wind, and a wind farm. Generation of electricity generated by such method is very separate from a site that effectively uses electricity, and thus there is a cost of electricity transmission.

In the generation of wind energy that generates energy in general directly using an external wind, there is a problem in which electric power is not properly generated with less wind.

In addition, because an axis of rotation of a wind blade is vertically fixed by gravity, a problem is that a fatigue fracture occurs in a fixing portion by a blade weight and it is difficult to decrease a frictional force of the shaft of the blade. rotation.
