Each one or more stages of the on-off valve 36 connected to be opened and closed each integrally to be opened according to the wind speed, and the one or more generators 82 to generate electrical energy, and the detection sensor Control unit 85 for adjusting the direction of the wind turbine rotor (1) by the wind direction detection of 84, and a drive motor 88 for rotating the wind turbine rotor (1) or the support (81). ), And installed on the wind turbine rotor (1) It consists of a drive unit 42 and a power supply unit 86 for supplying power to the drive motor 88.

That is, the wind power generator 70 is similar to the embodiment of the wind power generator 70 described in the first embodiment, except that the wind power generator 70 is the sensing sensor installed in the wind power generator 70 ( When the wind speed is sensed by 84, the control unit 85 performs the one or more on / off valves 36 which are integrally connected to each stage in accordance with the current wind speed condition by the signal of the sensor 84. The driving unit 42 is to be driven to open a stage or a plurality of stages.

Therefore, the area of the blade 30 of the wind turbine rotor 1 configured in the wind turbine 70 is controlled by the control unit 85 according to the wind speed, thereby adjusting the area of the wind turbine. By minimizing the resistance, the rotational force of the wind turbine rotor 1 can be kept constant, and of course, the wind turbine rotor 1 can be prevented from being damaged by strong winds such as typhoons. .

What has been described above is merely an embodiment for implementing a wind turbine rotor and a wind turbine using the same, the present invention is not limited to the above embodiments, as claimed in the claims below Without departing from the gist of the present invention, anyone of ordinary skill in the art will have the technical spirit of the present invention to the extent that various modifications can be made.
