專利名稱：一種具有較高風(fēng)能利用效率的垂直軸風(fēng)力發(fā)電機(jī)的制作方法
技術(shù)領(lǐng)域：
本發(fā)明涉及一種發(fā)電裝置，特別是一種高效率垂直軸風(fēng)力發(fā)電機(jī)，屬風(fēng)力發(fā)電 技術(shù)領(lǐng)域。
背景技術(shù)：
風(fēng)力發(fā)電機(jī)根據(jù)主軸安裝方位分為水平軸和垂直軸，迄今為止應(yīng)用較為普遍的 是水平軸風(fēng)力發(fā)電機(jī)。水平軸發(fā)電機(jī)盡管應(yīng)用普遍，但結(jié)構(gòu)上存在一些問題，如需要 偏航、對槳等迎風(fēng)和控制迎風(fēng)面增大阻力差的結(jié)構(gòu)，這使發(fā)電機(jī)的結(jié)構(gòu)復(fù)雜、占用零部 件多且容易造成故障。基于水平軸發(fā)電機(jī)的結(jié)構(gòu)缺陷，近年來，垂直軸發(fā)電機(jī)技術(shù)發(fā)展 迅速，應(yīng)用日益廣泛。垂直軸發(fā)電機(jī)可通過對葉片結(jié)構(gòu)的優(yōu)化設(shè)計(jì)，增大風(fēng)阻力，提高 風(fēng)阻力差，使風(fēng)機(jī)即使在較低的風(fēng)速下仍可以正常啟動(dòng)運(yùn)行，無需偏航、變漿裝置，因 而結(jié)構(gòu)相對簡單。垂直軸發(fā)電機(jī)關(guān)鍵技術(shù)是葉片結(jié)構(gòu)的設(shè)計(jì)，葉片形狀優(yōu)劣直接影響其 啟動(dòng)性能和風(fēng)能利用效率。目前，垂直軸發(fā)電機(jī)存有升力型葉片自起動(dòng)性能差、低風(fēng)速 發(fā)電性能差，阻力型風(fēng)能利用效率低等問題，因此優(yōu)化葉片結(jié)構(gòu)是解決上述問題的關(guān)鍵 所在。

發(fā)明內(nèi)容
本發(fā)明用于克服已有技術(shù)的缺陷而提供一種能量轉(zhuǎn)換利用率高、低風(fēng)速發(fā)電性 能優(yōu)良的具有較高風(fēng)能利用效率的垂直軸風(fēng)力發(fā)電機(jī)。本發(fā)明所稱問題是由以下技術(shù)方案解決的

全文摘要
一種具有較高風(fēng)能利用效率的垂直軸風(fēng)力發(fā)電機(jī)，構(gòu)成中包括中心柱、葉片和橫撐桿，各葉片垂直設(shè)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(jìn)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(cè)為鉤狀端，鉤狀端朝外設(shè)置。本發(fā)明通過對葉片及橫撐桿截形的優(yōu)化設(shè)計(jì)，可明顯增大風(fēng)阻力，提高風(fēng)阻力差，尤其是風(fēng)機(jī)在較低風(fēng)速下的發(fā)電能力可大幅度提高。對比試驗(yàn)表明，與同類垂直軸風(fēng)力發(fā)電機(jī)相比，本發(fā)明低風(fēng)速時(shí)發(fā)電機(jī)發(fā)電電壓提高近10倍，高風(fēng)速時(shí)發(fā)電電壓提高50%以上。
