Abstract

The invention relates to the technical field of wind power blade parts manufacturing, in particular to a molding method for the root bolt structure of wind power blades, comprising the following steps: fabric laying: laying at least one layer of fabric in the mould; bottom filler setting: composite The material filling is placed in the cavity formed after the fabric is laid; the setting of the metal screw sleeve: the metal screw sleeve of the bolt structure is placed on the placed composite filling; the setting of the top filling: the composite filling Set on the metal screw sleeve that has been placed; Closing of the fabric edge: Closing the exposed two ends of the fabric; Forming: Forming the combined structure in the mold. Through the invention, the quality of the blade root can be effectively guaranteed, the connection reliability between the bolt sleeve and the composite material and the bearing capacity of the root bolt can be improved, and the service life and safety of the product can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of manufacturing wind power blade components, in particular to a forming method for a bolt structure at the root of a wind power blade. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. China's wind energy reserves are large and widely distributed, and the wind power industry has developed rapidly, becoming one of the world's major wind power markets after Europe, the United States and India. [0003] According to the comprehensive survey and development trend analysis of China's wind power blade market status from 2019 to 2025 released by China Industry Research Network, fan blades are the key core wind turbine components for the progress of wind energy technology, and their good design, reliable quality and superior performance are the guarantees. Determinants of normal and stable operation of the unit. The de...
