AI Technical Summary

Technical Problem

Existing wind turbine main shaft components are prone to problems such as elliptical deformation, stress concentration, and wear during use. Traditional repair methods have problems such as high risk of welding heat damage, difficulty in installing the integral steel ring, and inability to carry out rapid on-site construction, which cannot meet the needs of rapid installation, lightweighting, and extended service life.

Method used

A split-type carbon fiber radial support device is adopted, which is spliced ​​into a ring support structure by multiple arc-shaped trapezoidal blocks. Combined with carbon fiber reinforced composite materials and interlocking positioning structure, it achieves support with no heat damage, lightweight and high strength. The installation method includes surface pretreatment, laying of buffer transition layer, splicing positioning and curing of outer wrapping layer.

Benefits of technology

It achieves safe construction without heat damage, convenient on-site installation, lightweight and high-strength support, significantly improves the uniformity of stress distribution, extends the service life of the wind turbine main shaft and reduces operation and maintenance costs.
