Description

垂直轴风力发电机增能翼的位移机构 技术领域 本发明属于风力发电机技术领域， 提供一种垂直轴风力发电中的构 件， 尤其是一种带有增能翼的垂直轴风力发电机中增能翼的位移机构。 背景技术 在现有技术中， 垂直轴风力发电机越来越显示出其效率高、 功率大和 便于安装使用、 寿命长等优点。 但是， 在风轮被风吹动旋转时， 风轮的转 动速度并不能随风力成比例增加，在风力不是很大的情况下这一情况更加 突出， 究其原因是， 当来风气流冲击风轮时， 在其迎风面的一侧受到的是 使得风轮转动的有效推力， 而在另一侧受到的则是阻止风轮转动的阻力， 上述两种力的合力是推动风轮旋转作功的有效动力。 由于迎风面上一侧风 阻的存在， 显著降低了垂直轴风轮的有效受风性能， 使得发电机的效率降 低。
现有技术中解决这一问题的方法是在风轮迎风面设置导流装置，使得 来风按照导流装置提供的通道吹向风轮而推动风轮转动，构建一个导流风 场。这种通过将自然风引入导流通道，再推动风轮叶片消除风阻力的方法， 存在降低自然风的风力的缺点， 同时， 自然风的风向会频繁变化， 如果导 流装置不随风向改变导流方向， 导流装置带来的风能损耗将更大， 如果设 计可以随风向变化而改变导流方向的导流装置，势必使得导流装置的结构 变得复杂， 这给在风场这样特定的、 往往也是严酷的环境中的使用、 管理 和维护都会带来不便。
