    • A wind mill structure of a lift-type vertical axis wind turbine. The lift-type vertical axis wind turbine includes a vertical shaft and the wind mill includes a plurality of blades and supporting arms. The supporting arms hold the blades, and the blades are connected to the vertical shaft via the supporting arms. A setting angle, formed by a chord of the blades and a tangent line that goes through the center of the blades, ranges from −12° to 12°. An angle, formed by the chord of the blade and the rotatable supporting arm, ranges from 7° to 100°. The wind mill can maintain relatively stable rotation speeds under wind speeds exceeding the rated wind speed by adjusting the angle of the supporting arms, thereby ensuring stable output from the vertical axis wind turbine.
    • 升降式立轴风力发电机的风车结构。 升降式垂直轴风力涡轮机包括竖直轴,风车包括多个叶片和支撑臂。 支撑臂保持叶片,叶片通过支撑臂连接到垂直轴。 由叶片的弦和通过叶片中心的切线形成的设定角度为-12°至12°。 由叶片和可旋转支撑臂形成的角度范围为7°至100°。 通过调整支撑臂的角度,风车可以在超过额定风速的风速下保持相对稳定的转速,从而确保来自竖直轴风力涡轮机的稳定的输出。
