Abstract
【解決手段】鉛直回転軸のまわりに、複数の縦方向のブレードをほぼ等間隔で設けた揚力型の風力発電用風車において、各ブレードを前部ブレードと後部ブレードに縦方向に二分して記後部ブレードを前部ブレードに対して分割線を回転軸に回動可能に軸支し、各前部ブレードを鉛直回転軸側に傾斜させた風力発電用の風車と発電装置。風速に応じて後部ブレードが回動し起動時または微風下ではサボニウス型の抗力型として機能し、高速時にはジャイロ型の揚力型として機能する。発電機は、鉛直回転軸の下方に設置され、風車と同軸的に連結される。
【選択図】図1
Description
また、構造が簡単なので、小型や中型の風車を安価に製造することができ、管理メンテナンスも容易である。
なお、これらの図の中で、同一部分については同一符合を付す。
前部ブレード3aの外側の翼面の後縁部は後部ブレード3bの前縁部よりも後方に延長されて後方カバー31aとなり、後部ブレード3bの全幅の30〜100%、好ましくは50〜70%がこの後方カバー31aに覆われた状態になっている。なお、後方カバー31aの幅は、所定の風速以上になったとき、後部ブレードの翼端に発生する遠心力が抗力より大きくなるような幅とする。
後部ブレード3bは、無風時又は微風時には、自重により、図1に示した状態となっており、前部ブレード3aの後方カバー31aと後部ブレード3bがなすサボニウス構造の凹部に後方又は斜め方向からの風を受けて微風の状態でも効率よく抗力を発生しブレード支持杆5、ハブ6を介して回転モーメントを鉛直回転軸2に伝達する。
