Straight-blade vertical-axis wind driven generator

Abstract

The invention provides a straight-blade vertical-axis wind driven generator. The pitch angle of a blade of the wind driven generator can be adjusted. The wind driven generator comprises a pitch angle control unit for adjusting the pitch angle of the blade of the wind driven generator, an opposite wind direction control unit and a blade bearing unit; and the pitch angle control unit comprises a connecting mechanism movably connected with the blade, and a guide mechanism installed at the bottom end of the blade, the guide mechanism comprises a control ring and a control track which are arranged below the blade, the control ring and the control track are matched so that the pitch angle of the blade can be changed when the blade rotates, wherein the control track is an annular track with a variable polar radius. 本发明提供一种直叶片垂直轴风力发电机，所述风力发电机的叶片的俯仰角能够被调节，所述风力发电机包括对所述发电机的叶片的俯仰角进行调节的俯仰角控制单元，所述俯仰角控制单元包括与所述叶片形成活动连接的连接机构；以及安装在所述叶片底端的导向机构，所述导向机构包括设置在所述叶片下方的控制环和控制轨道，所述控制环和控制轨道配合使得当所述叶片旋转时所述叶片的俯仰角能够被改变，其中，所述控制轨道为具有变化的极径的环形轨道；以及对风向控制单元和叶片承重单元。
