[0002] With the adjustment of the global energy structure and the rapid development of renewable energy, offshore wind farms, as a clean, renewable energy source, have received widespread attention and application. Offshore wind farms typically refer to facilities built in offshore waters that utilize wind energy for power generation. Their wind turbines are typically installed on fixed foundations or floating platforms at sea, utilizing the abundant offshore wind energy resources to generate electricity.

[0003] However, offshore wind farms face numerous challenges due to their unique operating environment. The maintenance of offshore wind turbine blades is particularly critical. As a core component of a wind turbine, blade performance directly impacts the turbine's power generation efficiency and operational stability. However, the complex offshore environment, particularly salt spray corrosion, accelerates blade aging and severely impacts its service life. While existing offshore wind turbine maintenance equipment can meet basic maintenance needs to a certain extent, it still lacks a targeted solution for effectively combating salt spray corrosion.
