The present invention relates to a wind turbine, and more particularly, to a wind turbine that is suitable for improving the wind power generation efficiency of high-altitude wind turbines.

Fossil fuels, such as petroleum, coal, and natural gas, which are generally used, can be exhausted not too far due to the limitations of underground resources. It is becoming a major culprit that causes warming and destroys the natural environment.

Accordingly, much attention has been paid to wind power generation technology, which is one of the most advantageous renewable energy, both technically and economically, which is permanently available and does not pollute the environment.

Generally, wind power generation technology is classified into onshore wind power generation technology and offshore wind power generation technology. These technologies are fixedly installed on land and offshore. These technologies include a blade and a generator using a rotational force of the blade. It consists of a nacelle, a main post supporting the nacelle, and the like.

Since the conventional wind power generation technology is installed at fixed positions on land and at sea, it is impossible to operate in a wind-free condition, and because it is a structure in which one generator is installed in one power generation facility, power efficiency is achieved. There is no choice but to increase the size of the blade in order to increase. In addition, since the structure of the rigid body such as the main post, the blade, etc. is included, the risk of breakage accident due to the gust can be increased.

In order to compensate for such drawbacks, a technique has been proposed in which a blade is installed on a post of a relatively flexible material and an airship is installed on the post to prevent the entire structure from falling.

However, even in such a structure, not only the blade is difficult to manage, but also there is a disadvantage in that there is a structural limitation in improving the power efficiency.

Therefore, an embodiment of the present invention is to propose a wind power generator that can increase the wind power generation efficiency as compared to the fixed wind power generator.

In addition, an embodiment of the present invention, by connecting a plurality of airships to each other, by collecting the electricity generated through each airship through the wire to propose a wind power generation device that can increase the wind power generation efficiency.

The wind power generator according to the embodiment of the present invention includes an airship supported from the ground, a plurality of wires extending below the airship, and a wind power generation unit supported by the plurality of wires and generated by wind. The wind power generation unit may include a propeller rotating by wind, a shaft extending in the longitudinal direction of the airship, coupled to the propeller, and rotating in accordance with the rotation of the propeller, and corresponding to the rotation of the shaft. A generator to generate, a power supply line for supplying power generated through the generator to the ground, a connecting beam having a predetermined horizontal width perpendicular to the longitudinal direction of the airship, and the peripheral beam disposed around the connecting beam A support beam forming a polygon together with connecting the shaft, the shaft of the polygon Located at the position of the vertex, the connecting beam may be located at the position of the horizontal longest inner side of the polygon.

Here, the power supply line, the first power supply line for supplying the power to the airship while fixing and connecting the generator and the airship, and the second power supply line for supplying the power supplied to the airship to the ground It may include.

In addition, the second power supply line may be connected to the airship by a hinge anchor.
