Alignment and fastening structure for use in e.g. windmill power plant, has insertion alignment pin and bushing precisely aligned at complementary point to alleviate association of set of frames of set of blade body sections

摘要

The structure has a set of frames (130) of set of blade body sections (100), where one of the frames for the sections including an insertion alignment pin (160) in predetermined point extending up to an outer side (135) and perpendicular to the outer side of the opposite frames. One of the frames of the sections includes a bushing at predetermined complementary point for the insertion alignment pin of the opposite frames. The insertion alignment pin and bushing are precisely aligned in complementary point to alleviate association of a set of frames of a set of sections.
