如图 10所示, (3 ) 利用起重机 4将第三叶片单元 23吊装到中心塔柱 1上, 吊装过程中, 第三叶片单元 23的行走小车 6在中心塔柱 1的导轨 7 上行走, 直到第三叶片单元 23位置确定后停止, 利用电动锁将第三叶片单 元 23固定在导轨 7上,并且利用第一连接结构和第二连接结构将第三叶片 单元 23与第二叶片单元 22连接起来, 以完成整一个叶片的安装;
(4) 安装上述步骤 (1 ) ~ (3 ), 完成风轮的其他叶片安装。
拆卸叶片 2的步骤是按照先拆卸第三叶片单元 23, 在拆卸第二叶片单 元 22, 最后拆卸第一叶片单元 21。在遭遇强风时, 通过拆卸风轮来保护发 电机及叶片免受损坏。
本发明 Φ形风轮由若干叶片组成, 每个叶片由若干叶片单元组成, 体 积更小的叶片单元能够有效解决大型垂直轴风力发电机风轮运输及安装较 难的问题, 进一步降低发电成本。
