Description

[0001] APPARATUS FOR GENERATING BY WIND POWER [0002]

The present invention relates to a wind power generator, and more particularly, to a wind power generator capable of increasing wind pressure and minimizing a drag force, and also capable of generating stable power by generating a rotary power by a strong rotation moment action, Generating device.

Generally, a wind power generator is a device that generates electric power by generating mechanical energy by wind force and then converting it into electric energy. Wind energy due to wind is infinite and clean, so it is recognized as an alternative energy.

As a new alternative energy generation device, the wind power generation device has a sufficient possibility. However, it is difficult to move the blade when the wind speed is low (for example, about 2 to 6 m / sec) There is a problem in that the efficiency of power generation is remarkably low.

To solve such a problem, Korean Patent Registration No. 10-1206701 discloses a wind turbine generator capable of generating wind at low wind speed. Such a wind turbine generator includes an air foil type wind capturer which generates an overlapping force in the same direction by constituting an overlapped region with respect to the center shaft, thereby enabling the use of drag and lift of wind simultaneously, And accelerated the output coefficient so that wind power can be generated even in a small wind.

However, since the conventional wind power generation apparatus including the above-described prior art for generating power even at low wind speed is capable of increasing the rotational power of the blades by focusing the wind mainly by the shape and arrangement of the blades, When the wind speed is changed to 2 / sec or less, the rotation of the blades is rapidly lowered and the power generation efficiency is lowered. In addition, in the case of a strong wind such as a typhoon, the blades are excessively rotated to cause damage or breakdown of the blades, .

On the other hand, in the 'wind turbine generator' of Japanese Patent No. 1815067 and No. 1817229 disclosed by the inventor of the present invention, it is possible to generate stable power by generating rotational power by a strong rotation moment action even when the wind speed is low. The present invention has another type of wind turbine generator which is simple in structure and greatly improved power generation efficiency based on the technical content.
