The invention relates to a sail type wind energy power automatic conversion method and a device, belonging to the technical field of wind energy conversion. The technical scheme is: the multiple sail wind power and turns to undertake common rotation driven wind generator connected with the rotation, output power, wind automatic conversion; the sail includes at least an activity and a matched sail sail sail leaf rachis, activities are arranged on the sail leaf axis, rotation range the activities of the sail leaf limited to less than 90 degrees. The invention can generate huge energy at low speeds, solidity ratio; low wind speed (a wind) can start, high wind speed can automatically change the work point of sail, in strong winds can also be normal operation, ensure the stability of the speed; the invention can rely on wind energy automatic control, automatic operation, automatic conversion, reasonable structure, low cost, high wind energy conversion efficiency.

1.一种帆式风能动力自动转换方法,其特征在于采用多个风帆轮流承接风能动力并共同转动,带动与之连接的风力发电机转动,输出动力,实现风能自动转换;所说的风帆包括至少一片活动帆叶和与之匹配的帆叶轴,活动帆叶设置在帆叶轴上,活动帆叶的转动范围限制在90度以内,帆叶轴在活动帆叶上偏心设置,将活动帆叶分为面积大小不等的两部分,面积较大部分的重量大于等于面积较小部分的重量;风帆共同转动的圆周,被风力方向分割成做功区和非做功区,风力吹到位于做功区的风帆上,活动帆叶垂下,承受风力并带动风帆转动做功,风力吹到位于非做功区的风帆上,活动帆叶与风平行,减少阻力,不承受风力,随风帆一起转动,转动至做功区活动帆叶垂下做功,如此往复完成风力转换。
