The whole of operations can be automatically controlled by the help of a monitoring anemoscope and anemometer 9 and a computer 11.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention can rotate a windmill and generate power regardless of whether or not there is a wind.

[0002]

2. Description of the Related Art Conventional wind power generation has relied only on wind power, so that the wind power has been weakened, and in the absence of wind, the rotation of a windmill has been slowed down or stopped, and power generation has also been stopped.

[0003]

In the case of wind power generation, no power is generated unless wind is generated. However, according to the present invention, a windmill can be rotated even when there is no wind. Therefore, the present invention
This solves one of the methods of generating electricity by turning a windmill even when there is no wind.

[0004]

A solar power generation device is used in combination with a wind power generation device. At this time, the photovoltaic power generator may be installed separately from the wind power generator, but it is preferable to mount the photovoltaic power generator on the body of the wind power generator because it is compact. In addition, an electric motor (2) using electricity of solar power generation as a power source is attached to a tip of a propeller (3) for rotating a windmill of a conventional wind power generator. (B) When the wind is the only required wind power to the power generator or when the wind power stops, the wind power is turned into a wind turbine instead of the wind power and the function of the wind power generator is connected. (B) When the wind power becomes weak or the number of revolutions required for power generation does not reach the level required for power generation, the shortage is compensated for by the solar power generator. (C) Store electricity in advance in case sunlight cannot be obtained.

[0005]

When the wind power required for rotating the wind turbine of the wind turbine is not obtained, the propeller is rotated by the electric motor attached to the tip of the propeller of the wind turbine to rotate the wind turbine. Switching from the wind to the electric motor is determined by a computer based on the measurement of the wind anemometer, and the electric motor is instructed to switch automatically. In addition, the switching from the electric motor to the wind rotation is automatically determined by the computer based on the measurement of the wind anemometer.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. If there is wind, there is no problem, but if the wind becomes weak or the wind stops, the tower (12) will be described. Each data obtained by the wind anemometer (9) attached to is analyzed and judged by the computer (11),
The electricity obtained by the photovoltaic power generators (4), (5) and (13) is automatically transmitted to the electric motor (2) installed at the tip of the propeller (3) of the wind turbine according to the instruction of the computer (11),
The propeller (1) is rotated to set the number of revolutions of the propeller (1) with a computer, and is rotated to rotate the windmill. The angle of the propeller (3) of the windmill is adjusted by the angle changing device (7) to reduce the resistance of the rotation of the windmill. By this operation, the rotation of the wind power generation device is maintained and the stop of the power generation is prevented. When wind power comes out, the data of the wind anemometer (9) is analyzed by the computer (11), and the data is switched to wind power. In this case, the propelling propeller (1) falls backward along the propeller (3) of the windmill as shown in FIG. 2 so as not to obstruct the rotation of the wind power.

In the case of wind power, when the electric motor (2) having uneven rotation and the propeller (1) are used, the motor rotates smoothly. However, since the propulsion is performed by the propeller (1), the rotation speed is low, and the wind pressure affects the rotation speed behind the propeller (1). Therefore, it is necessary to consider a third propulsion device. It can be solved by improving it.

[0008]

According to the present invention, since the solar power generation device is used in combination with the wind power generation device, even when there is no wind, or when the wind becomes weak or the number of revolutions required for power generation is not reached, the solar light generation device is not used. This can be supplemented by a power generator, and the windmill can be rotated to generate power regardless of the wind.
