Abstract
The invention provides a fan blade protective sleeve which comprises a protective sleeve body. The protective sleeve body is made of soft ductile materials and is used for being arranged on the side face of a fan blade in a sleeved mode. The protective sleeve body is in a cylinder-shaped structure with two ends opened, and a wind rope is fixedly connected with the outer side face of the protective sleeve body. Positioning belts which are used for being attached to the side face of the fan blade are arranged on the inner side face of the protective sleeve body along a circumferential direction. The positioning belts are fixedly connected with the inner side face of the protective sleeve body, and one ends of the positioning belts are fixedly provided with dismounting ropes which are used for enabling the positioning belts and the inner side face of the protective sleeve body to be separated from being connected. The fan blade protective sleeve can be sleeved at the position which is far away from the sharp portion of the fan blade on the fan blade, the potential risk that the sharp portion of the fan blade can be snapped when the blade is adjusted by pulling the wind ropes is removed, and the fan blade is prevented from being damaged in hoisting process.
