[Background Art]
A propeller-type windmill, a Savonius type windmill, a Darrieus type windmill, a multi-wing type windmill of U.S.A., and a helical type windmill are representative ones of the related art.
[Disclosure] [Technical Problem]
It is an objective of the present invention to provide a rotational plate for windmill, which facilitates assembly according to local environment while adjusting the number of wings for producing a required power.
[Technical Solution]
In one aspect, the invention is directed to four kinds of circular rotational plates for windmill, wherein each of the rotational plates has a boss inside for safe rotation and is safely coupled to a wing pole having different configuration so that they are integrated to have a rotational power.
[Advantageous Effects]
According to the present invention as described above, the windmill can be easily installed while the number of wings is adjusted depending on the wind speed and local site such as in areas such as general houses or islands having an average wind speed of 2 m/s, 3 m/s, 4 m/s, 5 m/s, so that an electric power generation efficiency can be enhanced by a small amount of electric power.
[Description of Drawings]
The foregoing and other objects, features and advantages of the invention will be apparent from the more particular description of preferred embodiments of the invention, as illustrated in the accompanying drawings.
The drawings are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the invention.
