AI Technical Summary

Technical Problem

Traditional offshore wind turbine towers cannot effectively adjust to changes in water level, causing the water level fluctuation zone to be exposed to ultraviolet radiation after seawater erosion. This further accelerates the damage to the anti-corrosion coating on the tower surface, reducing structural strength and anti-corrosion performance.

Method used

A corrosion-resistant offshore wind turbine tower assembly structure was designed, including a tower in the water level fluctuation zone, an assembly tower ring, and a protective mechanism. It utilizes a cleaning component driven by tides and sea breezes for automatic cleaning, and combines a transmission component and a locking component to achieve rapid assembly and locking. Multi-layer anti-corrosion layers are used to improve structural strength.

Benefits of technology

It effectively prevents ultraviolet rays from damaging the tower, keeps the tower surface clean, extends service life, reduces maintenance costs, improves assembly efficiency and stability, and enhances corrosion resistance.
