Abstract

本发明提供了一个结构简单、成本低的带导风板的双层风筒式风力发电机，由于本发明可利用水平方向360度风力发电，无需再对角度；每层设备由导风板引导汇聚的风都可分成内外两层带动发电机发电，提高了风能利用率；既结合了垂直轴水平方向风力可全方位发电的优点，又解决了垂直轴风力发电机风能利用率低的问题。

Description

导风板式双层风筒风力发电机
本发明涉及一种发电机，特别是涉及一种风力发电机。
目前现有的风力发电机技术，大致分为两类。一类是水平轴风力发电机，其优点是工艺成熟、结构简单、风能利用率高；但其存在工作中需要追寻风向、需要对缠绕的电缆进行解缆、大型机叶片材料要求高、加工难度高和抗强风难度大等缺点。另一类是垂直轴风力发电机，包括S型、H型和Φ型机等，其优点是无需对风向，水平方向风力可全方位发电；但其存在风能利用率低的缺点。
本发明的任务是提供一个结构简单、成本低的带导风板的双层风筒式风力发电机，既要解决发电机需要对风向、需要解缆的问题，又要解决水平方向风力可全方位发电的问题，还要解决垂直轴风力发电机风能利用率低的问题。
为达到上述目的，本发明实现方法如附图1或附图2所示，下导风筒1通过导风挡版2与上导风盘3相连接并固定，导风挡板2以设备中心线为轴心，在水平面上呈360°环形阵列，上导风盘3为中空的圆盘形，内缘向上翘起，下导风筒1为下大上小的喇叭形筒，其直径较小的上口的内部形成内出风口10，下导风筒1的上口与上导风盘3内缘有一定空间，形成外出风口11；发电机7通过支架6与下导风筒1固定；外圈风叶4通过固定环8和内圈风叶5固定在轴套9上，并在固定于发电机轴头后，可带动发电机主轴自由旋转，外圈风叶4和内圈风叶5中的每个叶片，以其伸展方向为轴心，相对于风叶旋转平面，有一个偏转角。
多台机(两台以上)经由下至上累加并且固定(最下层的设备，内圈风叶5由固定板代替)构成本发明设备，如示意图附图1所示。
下面结合附图和具体实施方式对本发明作进一步详细的说明。
图1是本发明累加后拼接成整体设备的示意图；
图2是本发明单体机设备的三视图；
图3是本发明单体机设备的主视图放大图。
参照图2，水平向风力无论从哪个角度吹向本机，都会先遇到下导风筒1和导风挡板2，受下导风筒1、导风挡板2和上导风盘3的引导向上从外出风口11处吹出，同时推动外圈风叶4旋转，带动发电机发电；由外出风口11吹出的风力经由其上一层设备的下导风筒1汇聚，从该层设备内出风口10处吹出，推动该层内圈风叶5旋转，带动该层发电机发电。
参照图1，每层设备都可由导风板引导汇聚的风推动该层外圈风叶4旋转，带动发电机发电；除最下面第一层设备无有内圈风叶5外，其余各层内圈风叶5都可受其下层上升风力作用带动发电机发电。
由于本发明中导风挡板2在水平面上呈360度环形阵列，故可利用水平方向360度风力发电，无需再对角度；发电机轴虽是垂直放置，但其风叶却是在以水平轴方式工作，既解决了发电机需要对风向、需要解缆的问题，又解决了水平方向风力可全方位发电的问题，还解决了垂直轴风力发电机风能利用率低的问题。
