Abstract
A bolt sleeve connector, a blade of a wind turbine generator system and manufacturing method thereof and a wind turbine generator system are provided. The bolt sleeve connector includes at least two extension portions arranged side by side and spaced apart, and each extension portion has a first end and a second end. The first ends of the extension portions are connected together and the second end of each extension portion is connected with the corresponding bolt sleeve. By using the bolt sleeve connectors to connect multiple pre-embedded connection sleeves at the position of the blade root of the blade of the wind turbine generator system, the multiple pre-embedded connection sleeves are connected as a whole, thus can disperse the stress of the bolt and the bolt sleeve and then improve the bearing capacity of the blade root bolt and facilitate reducing the weight of the blade root.
