The invention discloses a wind turbine blade rotating device. The wind turbine blade rotating device includes a blade root tool and a blade tip tool; the blade root tool is located at a blade root ofa blade and is rotatably connected with the blade root; the blade tip tool is located at a lifting point of a blade tip of the blade, and is connected with a blade main beam at the lifting point of the blade tip; the blade root tool drives the blade root of the blade to rotate, and the blade tip tool drives the blade tip of the blade to rotate with the rotation direction of the blade root, so as to adjust the placement direction of the cross section of the blade. According to the wind turbine blade rotating device, the blade root tool and the blade tip tool are divided, synchronous rotation between the blade root tool and the blade tip tool can be realized, and the problem of the blade damage caused by excessive torque generated by the blade root and the blade tip is solved.

    本发明公开了一种风力发电叶片转动装置,包括:叶根工装和叶尖工装;所述叶根工装位于叶片的叶根处,与所述叶根转动连接;所述叶尖工装位于叶片的叶尖吊点处,并与所述叶尖吊点处的叶片主梁连接;所述叶根工装带动所述叶片的叶根旋转,所述叶尖工装带动所述叶片的叶尖跟随所述叶根的旋转方向转动,以调节所述叶片的截面放置方向。本发明分为叶根工装和叶尖工装,其之间可以实现同步自转,解决叶根和叶尖产生过大扭矩,所引起的叶片损伤的问题。
