Description

带导风罩的风力发电机叶片装置
技术领域
本发明涉及风力发电机技术领域，更具体地说涉及一种风力发电机的叶片装置。
背景技术
风力发电机靠风叶利用风能产生机械能，由叶片推动发电机风轮旋转而发电。风能发电的运行效率，取决于叶片在空气动力作用下，叶片是否能充分获得风能量决定，风能利用率越宽泛，风能发电机发电效率就越高。
如图1所示，现有风力发电机的叶片的曲线形状虽受风能力较好，由于垂直轴外转子永磁发电机的磁阻力巨大，在3M／S风速时很难切入启动风机运转。为了确保风机机械结构的运行安全，考虑风力发电机组自身重量和体积及安装位置和高度限制，所以不可能将叶片设计的太宽太长。
发明内容
本发明的目的就是针对现有技术之不足，而提供带导风罩的风力发电机叶片装置，它增大了受风面积，一倍左右，提高了风能利用率，避免了自身重量和体积的增大。
本发明的技术解决措施如下：
带导风罩的风力发电机叶片装置，包括主叶片1，在主叶片1的后部固定有加强筋板2，加强筋板2上固定有导风罩3，导风罩3为具有弧形开口的罩体，导风罩3的前罩边31比后罩边32短，加强筋板2上成型有通风孔21。
所述加强筋板2、导风罩3和主叶片1通过螺钉固定一起。
本发明的有益效果在于：
1.它增大了受风面积，一倍左右。2.风叶第一次受风使叶片转动，余风进入前端的导风罩口，利用二次余风能量跟进推动。3.叶片旋转，变换角度后，使切入导风罩的风能从背后再次受风。4.导风罩的曲线风阻力小，双边的几何曲线与原叶片对称，高速时无哨叫声。5.导风罩前后通风面为前短、后长，前通风曲线短，进风口就大，后曲线长，风在导风罩内停留时长，推力就增加，降低了启动风速，提高了风能利用率，避免了自身重量和体积的增大。

具体实施方式
实施例：见图1至3所示，带导风罩的风力发电机叶片装置，包括主叶片1，在主叶片1的后部固定有加强筋板2，加强筋板2上固定有导风罩3，导风罩3为具有弧形开口的罩体，导风罩3的前罩边31比后罩边32短，加强筋板2上成型有通风孔21。
所述加强筋板2、导风罩3和主叶片1通过螺钉固定一起。
工作原理：导风罩3增大了主叶片1工作时的受风面积，主叶片1受风使叶片转动，余风进入前端的导风罩口，利用二次余风能量跟进推动。导风罩3的弧形开口使得导风罩前后通风面为前短、后长，前通风曲线短，进风口就大，后曲线长，风在导风罩内停留时长，推力就增加，降低了启动风速，提高了风能利用率，避免了自身重量和体积的增大。
