專利名稱：一種具有較高風能利用效率的垂直軸風力發(fā)電機的制作方法
技術領域：
本實用新型涉及一種發(fā)電裝置，特別是一種高效率垂直軸風力發(fā)電機，屬風力發(fā) 電技術領域。
背景技術：
風力發(fā)電機根據主軸安裝方位分為水平軸和垂直軸，迄今為止應用較為普遍的是 水平軸風力發(fā)電機。水平軸發(fā)電機盡管應用普遍，但結構上存在一些問題，如需要偏航、對 槳等迎風和控制迎風面增大阻力差的結構，這使發(fā)電機的結構復雜、占用零部件多且容易 造成故障。基于水平軸發(fā)電機的結構缺陷，近年來，垂直軸發(fā)電機技術發(fā)展迅速，應用日益 廣泛。垂直軸發(fā)電機可通過對葉片結構的優(yōu)化設計，增大風阻力，提高風阻力差，使風機即 使在較低的風速下仍可以正常啟動運行，無需偏航、變槳裝置，因而結構相對簡單。垂直軸 發(fā)電機關鍵技術是葉片結構的設計，葉片形狀優(yōu)劣直接影響其啟動性能和風能利用效率。 目前，垂直軸發(fā)電機存有升力型葉片自起動性能差、低風速發(fā)電性能差，阻力型風能利用效 率低等問題，因此優(yōu)化葉片結構是解決上述問題的關鍵所在。

實用新型內容本實用新型用于克服已有技術的缺陷而提供一種能量轉換利用率高、低風速發(fā)電 性能優(yōu)良的具有較高風能利用效率的垂直軸風力發(fā)電機。本實用新型所稱問題是由以下技術方案解決的一種具有較高風能利用效率的垂直軸風力發(fā)電機，構成中包括中心柱、葉片和橫 撐桿，各葉片垂直設置，它們相對中心柱軸線均勻分布，葉片由橫撐桿連接中心柱，其特別 之處是所述各葉片的截面形狀相同，所述葉片截形的一側為鉤狀端、且鉤狀端朝外設置。所述葉片截形輪廓由0-Q、0-R、P-Q、P-R四條曲線組成，四條曲線由下述參數確 定建立平面直角坐標系，以所述截形的一端為坐標原點，各曲線上相應點的坐標值 如下O-Q 曲線Xo0Yao0Xl1Yal0.6312X22Ya20.8929X33Ya31.1320X44Ya41.3510X55Ya51.5522X66Ya61.7376X77Ya71.9089X88Ya82.0674

專利摘要一種具有較高風能利用效率的垂直軸風力發(fā)電機，用于解決提高垂直軸風力發(fā)電機風能利用率及低風速發(fā)電性能。其技術方案是構成中包括中心柱、葉片和橫撐桿，各葉片垂直設置，它們相對中心柱軸線均勻分布，葉片由橫撐桿連接中心柱,改進后,所述各葉片的截形輪廓由O-Q、O-R、P-Q、P-R四條曲線組成，所述葉片截形的一側為鉤狀端，鉤狀端朝外設置。本實用新型通過對葉片及橫撐桿截形的優(yōu)化設計，可明顯增大風阻力，提高風阻力差，尤其是風機在較低風速下的發(fā)電能力可大幅度提高。對比試驗表明，與同類垂直軸風力發(fā)電機相比，本實用新型低風速時發(fā)電機發(fā)電電壓提高近10倍，高風速時發(fā)電電壓提高50%以上。
