The invention discloses a wind power generation blade rotating device, and relates to the technical field of wind power generation, the wind power generation blade rotating device comprises a movable supporting plate, a concentric rotating mechanism, a connecting seat and a fan blade, the concentric rotating mechanism comprises a connecting piece, a fixing hole is formed in the inner wall of the connecting piece, the connecting seat is fixedly installed with the fixing hole through a fixing piece, and the connecting piece is fixedly connected with the connecting seat; one side of the connecting seat is fixedly connected with the fan blade, the concentric rotating mechanism is arranged, and the annular supporting plate and the connecting piece are concentric, so that the blade root and the blade tip of the fan blade can rotate around the axial rotating center of the blade root of the fan blade even if the blade root and the blade tip of the fan blade are not on the same straight line due to different shapes; and the risk that when the two ends or one end of the fan blade is pulled to rotate through a lifting rope of a crane, due to different rotation speeds, amplitudes and rotation circle centers, the internal axial torque of the fan blade is too large, the internal stress is continuously changed, and deformation and damage are caused is also avoided.
本发明公开了一种风力发电叶片转动装置,涉及风力发电技术领域,包括移动支板、同心旋转机构、连接座与风叶,所述同心旋转机构包括:连接件,所述连接件内壁开设有固定孔,所述连接座通过固定件与固定孔固定安装,所述连接座一侧与风叶固定连接,通过设置同心旋转机构,因为环形托板与连接件是同心圆的关系,使得在风叶的叶根与叶尖即使因为形状不同,不在同一直线上时,也会以风叶叶根的轴向旋转中心进行旋转,也避免了风叶两端或者一端通过吊机的吊绳拉扯旋转时,由于旋转速度、幅度以及旋转的圆心不同,而出现风叶内部轴向扭矩过大,导致内部应力不断发生变化出现变形损坏的风险。
