AI Technical Summary

Technical Problem

Due to the increase in size of the large megawatt wind turbine, the overall transportation cost increases and cannot be transported beyond the limited size of the highway. The post-curing deformation of the fiberglass material leads to inaccurate hole positions, affecting assembly accuracy.

Method used

Design a large megawatt wind power multi-piece flow conduit assembly and high-precision inspection device, including the main platform, internal interface verification device and external interface verification device. The verification device simulates the blade hub interface, accurately detects the key size and angle of the flow conduit to ensure assembly accuracy.

Benefits of technology

High-precision inspection of the assembly of multiple pieces of the shroud is achieved, which avoids the difficulty of adjustment of later verification, improves product quality and production efficiency, and reduces transportation and assembly costs.
