Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a technology for increasing power generation efficiency by providing a magnet on one shaft end rotor and a coil on the other shaft end rotor of two wind turbines that are inverted with a tower interposed therebetween.
[0002]
[Prior art]
In a conventional wind power generator, since one wind turbine is installed in one tower, the only way to obtain a large amount of power in a limited space is to increase the size of the wind turbine.
[0003]
[Problems to be solved by the invention]
The only way for a conventional windmill to obtain a large amount of power was to increase the size or increase the number of windmills.
[0004]
Therefore, the construction of wind turbines has to move to a place where installation is more difficult due to the expectation of clean energy.
[0005]
The places where the windmills are already installed are limited places suitable for wind power generation.
[0006]
The present invention aims to increase the amount of power generation in a limited space and reduce the construction cost, which could not be achieved by a conventional wind power generator.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, in the dual wind turbine generator of the present invention, two wind turbines are installed on the same line with one tower interposed therebetween, and each of the wind turbines is received by two bearings. One of the rotors at the shaft ends of the two windmills has a large number of magnets and the other has a coil mounted thereon to form a multi-pole.
[0008]
[Action]
When the two rotors are inverted, the peripheral speeds of the magnet and the coil are relatively increased, producing a large amount of power in a limited space.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings. In FIG. 1, a dual wind turbine installed at the top of a tower In FIG. On the other hand, it receives wind efficiently. A large number of magnets 1 are provided on one shaft end rotor of the two wind turbines, and a coil 2 is provided on the other shaft end rotor, and the shafts of each wind turbine are received by two bearings 3 respectively. Since the two rotors constituting the multiple magnetic poles are inverted, the generated power can be increased. The current thus generated can be taken out as electric power through the brush 4.
[0010]
【The invention's effect】
The present invention is configured as described above, and has the following effects.
[0011]
By inverting the rotor, the relative peripheral speed between the magnet and the coil is increased, and a large electric power can be generated.
[0012]
Since it is installed in one tower, the limited space can be effectively used, and the installation cost can be extremely reduced.
[0013]
The remaining wind power in the conventional wind power generator can be used effectively.
[0014]
By replacing the already installed conventional wind turbine with the present invention, it is possible to use the same space at the conventional installation location to increase the amount of power and increase the power generation efficiency.
Of course, it is possible to generate more electric power in a newly installed location in the future.
