Abstract

垂直轴叶片是涉及风力发电机的垂直轴叶片结构的改进。本发明就是提供一种可提高风的利用效率的垂直轴叶片。本发明包括垂直中心轴，其结构要点垂直中心轴外均布有奇数个叶片，叶片的截面的一侧为流线弧形迎风面，相对迎风面的另一侧为凹形背风面。

Description

垂直轴叶片
技术领域：
本发明是涉及风力发电机的垂直轴叶片结构的改进。
背景技术：
风力发电机的叶片通常分为两种，一种是在平行于地面的轴上设置叶片，另一种是在垂直于地面的轴上设置叶片，称为垂直轴叶片。垂直轴叶片的发电装置可省去笨重的旋转平台；因此，结构相对比较简单，但目前叶片的结构不尽合理，影响了风的利用效率，也就影响了发电功率。
发明内容：
本发明就是针对上述问题，提供一种可提高风的利用效率的垂直轴叶片。
为实现上述目的，本发明采用如下技术方案，本发明包括垂直中心轴，其结构要点垂直中心轴外均布有奇数个叶片，叶片的截面的一侧为流线弧形迎风面，相对迎风面的另一侧为凹形背风面。
本发明的有益效果：
由于本发明的垂直中心轴外均布有奇数个叶片，叶片的截面的一侧为流线弧形迎风面，相对迎风面的另一侧为凹形背风面，无论什么风向，都可为本发明的叶片所充分利用，因此，可提高风力发电机的发电功率。
附图说明：
图1是本发明的结构示意图；
图2是图1的A-A剖视图。
具体实施方式：
本发明包括垂直中心轴1，垂直中心轴1外均布有奇数个叶片2，叶片2的截面的一侧为流线弧形迎风面5，相对迎风面5的另一侧为凹形背风面4。
为增加本发明的叶片2的强度，可在叶片2的迎风面5、背风面4之间设置有圆筒3，圆筒3分别同迎风面5、背风面4相连。
