Abstract

本发明属于垂直轴风力发电机风叶装置领域，包含外转子发电机和风叶片。其特征在于，在垂直轴风力发电机的风叶外，装一个导流罩，在风向导航标的作用下，风力对迎面风的一半风叶做功，另一半风叶由导流罩罩住，风的能量对导流罩内的叶片无反向做功，导流罩在风向导航标的指引下，始终对着迎面风，导流罩围着风叶做360°的自由运动。

Description

一种导流罩式垂直轴发电机风叶装置
技术领域：
本发明涉及垂直轴风力发电装置领域，尤其关于风叶装置范畴。
背景技术：
垂直轴风力发电机的风叶，由于垂直轴的风叶在转动作圆周运动时，必须要克服风力对它的叶面反向做功，虽然在叶片的设计上可以解决一些问题，但要在微风状态下，既要解决风力对风叶的反做功，又要解决叶片圆周运动直径过大问题，同时要克服电机起动力矩阻力，所以启动至运转很困难。
发明内容：
本发明的目的在于提供一种导流罩式垂直轴发电机风叶装置，既解决垂直轴电机在微风中启动，而且叶片圆周运动直径较小，并且能克服发电机起动力矩阻力，在微风中顺利起动，满负荷发电。
本发明解决上述技术问题的技术方案是：
导流罩式垂直轴发电机风叶装置，包含外转子风力发电机，和风叶片。其特征在于，在垂直轴风力发电机的风叶外，安装一个导流罩，罩住风叶片圆周运动的一半，在风向导航标的作用下，风力对一半迎风面的风叶做功。另一半风叶，由于有导流罩罩住，风的能量沿着导流罩的流体型表面吹向后方，对导流罩内的叶片无做功，导流罩在风力的作用下，在风向导航标的指引下，始终对着迎面风，导流罩在风向导航标的指引下，围着风叶做360°的自由运动。
本发明的有益效果是：既解决了风力对一半风叶的反做功，又解决了叶片圆周运动直径过大的问题，并克服发电机起动力矩阻力，能在微风的状态下，起动并满员负荷发电。
利用导流罩表面上安装太阳能光伏发电装置，在风力发电的同时，导流罩上的太阳能光伏发电装置也同时发电。
附图说明
图1是本发明的结构示意图
风叶1，外转子发电机转子2，风叶固定件3，外转子发电机定子轴4，导流罩下轴承5，导流罩上轴承6，风向导航标7，风叶8，导流罩9，外转子发电机定子10，固定端11。
具体实施方式：
本发明如图1所示，将外转子发电机定子10，安装在外转子发电机的定子轴4上，并将外转子发电机定子定位在外转子发电机外转子中心。风叶1,8，通过风叶固定件3，固定在外转子发电机的外转子2上，在定子轴上装上导流罩下轴承5，导流罩上轴承6。将风向导航标7，安装在导流罩9上，并整体固定在上轴承，下轴承上，同时对风叶做360°圆周自由运动，固定端11固定在支架上。同时在导流罩表面上安装太阳能光伏发电装置。
上述应用案例：导流罩直径1.5m，风叶5片，微风4.4m／s，离地10m，发电机起动力矩1N*M，转速360转／分，发电量1KW／h，导流罩上的太阳能光伏发电装置3.5m2，发电量达到600W／h。
