Abstract
縦軸型で抗力型水風車の起動性向上と水風流逆行時の抵抗を減じた回転効率改善と危険回転回避を簡易で速急に行う方法を提供する。
【解決手段】
縦軸型とする中心回転軸と回転対称にある翼は弓状の円弧で両端を支持板に固定された構造とし、その翼は幾つかの羽で構成され、その羽は垂直辺の一辺が羽回転軸に取り付けられ対辺をフリーとする、その回転範囲は、翼線形の円弧中心点側にあり、両側隣接羽回転軸までとする扇形範囲とし、水風車の翼が水風流に逆行する凸時には羽が水風流なびかせとなり開放され、さらに回動して翼が凹時には羽回転軸間を塞いで翼全面で水風圧を受け回動する。危険回避は、全羽を羽回転軸に羽の根元を半回転〜2回転巻き込み両側隣接羽回転軸間より羽の水平辺を短くして羽回転軸を中心に360°回転形態とし、水風車の回動力を失わせ全体の抵抗を大きく減じて危険を回避する。
