This study aims to address the issue of failures caused by corrosion in wind turbine towers,with the goals of reducing manual maintenance costs and improving safety.To achieve this,researchers have developed an intelligent equipment for corrosion protection and maintenance of wind turbine towers,and conducted research on the automatic spray performance of its coating module.The study combines the corrosion environment characteristics of wind turbine towers with the coating properties of the equipment,and carries out a series of indoor accelerated corrosion tests,including evaluations of UV aging,salt fog resistance,alkali resistance,and water resistance.Through these tests,the researchers evaluated the performance of commonly used anti-corrosion coating systems in wind turbines and selected a coating system suitable for the automatic spray module used in the corrosion protection and maintenance of wind turbine towers.These choices aim to meet the requirements of manual spraying and adapt to the conditions of corrosion protection and maintenance in typical tower environments.
