Abstract
本申请公开了双模态风力发电机，其叶片安装框架套接于垂直主轴；双模态叶片系统中包括的多个双模态叶片结构的顶端及底端均通过棘轮棘爪锁定结构连接于叶片安装框架，且多个双模态叶片结构环绕叶片安装框架均匀设置；每一双模态叶片结构均包括内侧叶片和外侧叶片，且通过棘轮棘爪锁定结构及内侧叶片的重力复位结构根据当前风速进行内侧叶片与外侧叶片之间张开角度的调节。本申请实施例中的双模态风力发电机能在不同风速下，无需传感器或外部驱动源，仅依赖风速变化引发内侧叶片与外侧叶片之间张开角度的调节，实现模式自动切换，使得双模态叶片系统在阻力型风机状态或升力型风机状态切换，能在正弦风场中实现连续稳定发电且提高了发电效率。
