Abstract

The present invention pertains to a wind power generator. The angular velocity and the radius of gyration of a rotating blade section are large so that power generation efficiency may be greatly improved and a low starting torque is excellent such that the rotating blade section may readily rotate despite low wind intensity. In addition, the noise generated by the wind in the process of the rotation of the rotating blade section may be largely reduced. In the case that the rotating blade section is damaged by external force or the like, the rotating blade section would not be exposed to the outside and thus accidents that may result from the damaged rotating blade section may be readily prevented. Furthermore, the appearance thereof may be aesthetically designed.

Since the rotary blade unit 30 is provided in the 110, when the rotary blade unit 30 is damaged by an external force or the like, the damaged rotary blade unit 30 does not have to be exposed to the outside of the cylindrical case 10. 30) it is possible to more easily prevent safety accidents, and also has the advantage that the appearance can be beautifully designed.
본 발명의 풍력발전기는 회전블레이드부의 회전각속도와 회전반경이 크기 때문에 발전효율이 보다 크게 향상될 수 있음은 물론 바람의 세기가 약하더라도 상기 회전블레이드부가 보다 용이하게 회전할 수 있는 즉, 저시동토크가 우수하고, 나아가 바람에 의해 상기 회전블레이드부가 회전하는 과정 중에 발생되는 소음을 크게 저감시킬 수 있을 뿐만 아니라 상기 회전블레이드부가 외력 등에 의해 파손된 경우 파손된 상기 회전블레이드부가 외부로 노출될 우려가 없어 파손된 상기 회전블레이드부로 인한 안전사고를 보다 용이하게 방지할 수 있고, 아울러 외관을 미려하게 디자인할 수 있는 이점이 있다.Wind turbine according to the present invention can improve the power generation efficiency because the rotational angular velocity and rotation radius of the rotary blade is large, of course, even if the wind strength is weak, the rotation blade can be more easily rotated, that is, low starting torque Is excellent, and furthermore, it is possible to greatly reduce the noise generated during the process of rotating the rotating blade unit by wind, and there is no fear of exposing the damaged rotating blade unit to the outside when the rotating blade unit is damaged by external force. Safety accidents due to the broken rotating blade unit can be more easily prevented, and the appearance can be beautifully designed.
