Description
The present invention relates to a wind turbine for a wind power generator having a variable wing capable of efficiently converting the force of the wind into mechanical energy, and more particularly, the wing of the rotating direction by the wing is folded or unfolded according to the direction of the wind Wing is located in the direction opposite to the direction of the rotation is wider and rotated to the wind relates to a windmill for a wind turbine having a variable wing that can improve the power generation efficiency by narrowing the area in contact with the wind.
In general, currently used power generation methods are widely used, such as thermal power generation using a large fossil fuel, nuclear power generation using uranium, and hydroelectric power generation requiring a large amount of fresh water. Since thermal power generation requires power generation by burning fuels such as coal or petroleum, a lot of combustion gas is generated to increase air pollution, and nuclear power generation does not emit combustion gases polluting the air, but a large amount of radioactive waste that is fatal to the human body is generated. It is discharged, hydroelectric power does not emit a combustion gas or radiation waste, etc. and does not require a separate fuel, while destroying the environment there is a problem that is not environmentally friendly. Recently, research on solar power generation and wind power generation, which are environmentally friendly and can use fuel permanently, has been conducted.
Wind power generation using dual wind power is a technology that obtains electric power by converting rotor into mechanical energy by using aerodynamic characteristics of kinetic energy of air flow. Are classified into a horizontal type and a vertical type according to the direction of the rotation axis with respect to the ground, and the main components include a rotor composed of a blade and a hub, a speed increaser for driving a generator by increasing the rotation of the rotor, a generator and various It consists of a control device for controlling safety devices, a hydraulic brake device, a power control device, and a steel tower.
In addition, wind power generation uses no-pollution and infinite wind scattered everywhere, so there is little effect on the environment, and the land can be used efficiently, and in the case of large-scale power generation facilities, power generation costs can compete with existing power generation methods. It is a level of new energy generation technology.
In such a wind generator, the windmill is converted into electrical energy by using kinetic energy rotated by the wind. At this time, the windmill theoretically converts about 60% of the kinetic energy of the wind into mechanical energy, which is then converted into electrical energy. Is converted to a lot of energy. Therefore, the conversion efficiency of converting wind energy into electrical energy is substantially different depending on the shape of the windmill, but it is only about 20 to 40%.
However, in the conventional wind power generation as described above, the wind is maintained at a constant speed or higher and the density of the air is high so that the kinetic energy of the wind is transmitted to the wings, and thus the windmill is rotated, thereby converting the kinetic energy of the wind into electrical energy. It is implied. In other words, when the wind is weak and the breeze blows, since the rotation of the windmill is weakened, the situation that the generation of wind power generation is impossible.
The present invention has been made to solve the conventional problems as described above, by installing the wings of the windmill to be folded or unfolded in accordance with the direction of the wind, so that the wings located in the direction of rotation of the windmill so that the area of contact with the wind is wider Unfolded, the wings located in the opposite direction of the rotation direction of the windmill is installed to be folded so as to narrow the area in contact with the wind is to provide a windmill for a wind turbine having a variable wing that can improve the power generation efficiency.
