Claims (3)
- 風上方向にブレードを備えたプロペラ型風力発電装置の可変ピッチ装置であって、複数のブレードを取付けるハブと、該ハブの中央位置に立設された回転中心軸と、該回転中心軸の軸方向に巻回して設けられたバネ材と、該バネ材の一端側に設けられ前記ブレード基端部側と当接する当接部材と、前記バネ材の他端側に設けられ前記バネ材を所定の付勢力で圧縮して固定する固定部材と、前記回転中心軸周りに基部固定部材を介して設けられた複数のブレードと、該基部固定部材及び前記ハブにブレードの中心軸に対してヒンジ軸が反時計回りに15度となるよう取付けられたヒンジとから構成され、風圧によって前記ブレードの先端部が前記バネ材の付勢に抗して風下方向に揺動すると共に、ピッチ角度を減少させることを特徴とする可変ピッチ装置。
- 風下方向にブレードを備えたプロペラ型風力発電装置の可変ピッチ装置であって、複数のブレードを取付けるハブと、該ハブの中央位置に立設された回転中心軸と、該回転中心軸の軸方向に巻回して設けられたバネ材と、該バネ材の一端側に設けられ前記ブレード基端部側と当接する当接部材と、前記バネ材の他端側に設けられ前記バネ材を所定の付勢力で圧縮して固定する固定部材と、前記回転中心軸周りに基部固定部材を介して設けられた複数のブレードと、該基部固定部材及び前記ハブにブレードの中心軸に対してヒンジ軸が反時計回りに15度となるよう取付けられたヒンジとから構成され、前記ブレードが遠心力によって前記バネ材の付勢に抗して揺動し、ピッチ角度を減少させることを特徴とする可変ピッチ装置。
- 前記ヒンジを前記ブレートの中心軸に対して時計回りに15度となるよう取付け、ブレードのピッチ角度を増加させることを特徴とする請求項1又は請求項2のいずれかに記載の可変ピッチ装置。
