Abstract

The invention relates to a manufacturing process method for integrated formation of a horizontal shaft segmented wind power blade and an integrated device applicable to the method. The wind power blade at least comprises two segments of composite material blade segments. A metal bolt sleeve is embedded into the connecting part of the two adjacent segments during manufacturing, and integrated formation is realized by a positive pressure auxiliary vacuum perfusion mode, so the defects of the traditional perfusion process are overcome, and the manufacturing problem of the segmented blade is solved. In addition, the integrated formation process avoids various disadvantages and risks caused by that the traditional process shell adopts adhesive to adhere.

Description

technical field [0001] The invention relates to a segmented wind power blade integrated forming process, in particular to a blade segmented manufacturing process and integrated forming method and an integrated device suitable for the method, which belongs to the key components of wind power generation equipment. Background technique [0002] With the increasingly prominent energy and environmental issues, wind power, as a clean energy and renewable energy, has received global attention and attention. With the investment in research and development in various countries, wind power technology has also made great progress, and the capacity of single wind turbines has continued to increase. From the initial kilowatt level to today's multi-megawatt level, the blade length has also increased from a few meters to more than 80 meters at present. At present, the longest blade commercialized has reached 61.5 meters, and larger and longer blades are also under development. Large-scal...
