Abstract

본 발명은 풍력발전기에 관한 것으로, 보다 상세하게는 무동력으로 특별한 모터나 제어장치를 구성하지 않아도 바람의 세기에 따라 블레이드에 의한 회전 정도를 조절할 수 있어, 풍력발전기의 구성부재들이 손상되는 것을 미연에 방지하도록 하는 블레이드지향각도조절부가 구비된 풍력발전기에 관한 것이다. 이와 같은 본 발명의 특징은 주축의 상부에 회전가능하게 결합된 다수의 블레이드의 회전에 의해 발전되도록 하는 풍력발전기에 있어서, 풍력발전기의 후방에는 바람에 의하여 작동되는 풍속감지판이 구비되고, 풍속감지판과의 연동으로 블레이드의 지향각도가 변화되도록 하여 발전부 회전자의 회전속도가 조절되도록 하는 블레이드지향각도조절부가 구비되는 것을 특징으로 한다.
