Wind power blade bolt sleeve embedded molding structure A wind power blade bolt sleeve embedded molding structure, which mainly includes the connection between the blade and the hub of the wind turbine. It is characterized by: a plurality of bolts near the middle position of the glass fiber reinforced structure at the root of the blade The sleeve is evenly, pre-buried and fixed on the corresponding position of the blade root, and the pre-buried bolt sleeve is wrapped with glass fiber unidirectional roving, and the gap between the bolt sleeves is embedded with wedge-shaped strips. The connection structure is together with the rest of the blade After the blade is formed, the connecting structure and the blade work together as a whole. Through the embedded bolt sleeve structure, a reliable connection between the blade and the hub can be realized. The structure can avoid processing damage to the root structure layer, and the force of the root structure is reasonable. The position and angle of the bolts are guaranteed by the positioning tooling, which is more accurate and guarantees the smooth installation of the impeller.
