Title: BOLT SLEEVE CONNECTOR, BLADE AND MANUFACTURING METHOD OF BLADE, AND WIND TURBINE SET
Abstract:
A bolt sleeve connector, a wind turbine blade, a manufacturing method for the wind turbine blade, and a wind turbine set. The bolt sleeve connector comprises at least two extensions (250, 350) arranged side by side and separated apart. Each extension (250, 350) has a first end (210) and a second end (220). The first ends (210) of the extensions (250, 350) are connected. The second ends (220) of the extensions (250, 350) are connected to corresponding bolt sleeves (206). Connecting multiple pre-embedded connecting sleeves by using bolt sleeve connectors at the blade roots of a wind turbine allows the pre-embedded connecting sleeves to be connected as a whole, further dispersing stress on bolts and blot sleeves, increasing bearing capacity of bolts at the blade roots and helping reduce the weight of the blade roots.
