Abstract
The invention relates to a tower of an offshore wind turbine generator. The tower comprises an outer wall of a tower body (1), a tower platform (21) outside the tower body (1), a rail (3) erected upwards the periphery of the tower platform (21), and a ladder (41) arranged between the tower platform (21) and the outer wall of the tower body (1) and coated with three corrosion-resistant coatings including an epoxy zinc rich priming paint layer (10), an epoxy micaceous iron intermediate paint layer (20) and a fluorocarbon surface paint layer (30). According to the invention, an inner wall of the tower body (1), a tower platform (22) inside the tower body (1) and a ladder (42) arranged between the tower platform (22) and the inner wall of the tower (1) are coated with three corrosion-resistant coatings including the epoxy zinc rich priming paint layer (10), the epoxy micaceous iron intermediate paint layer (20) and the fluorocarbon surface paint layer (30), so that the requirement that the service life of corrosion protection of the wind turbine generator in a marine environment reaches 30 years can be met.
Description
【Technical field】 [0001] The invention relates to a tower frame, in particular to a tower frame of an offshore wind power generating set. 【Background technique】 [0002] According to the ISO 12944-1 standard, long-term surface protection, the service life of the steel structure tower of the wind turbine is at least 15 years, and its anti-corrosion protection goal is to meet the 30-year service life requirements in the marine environment. 2. The steel structure corrosion level in the marine environment is C5-M, which is the area with the most severe corrosion environment and corrosion degree. It is also the key and difficult point of anti-corrosion protection. Protection brings severe challenges. In addition, once the anti-corrosion coating of offshore wind turbines fails, it is difficult and costly to repair. Therefore, it is crucial to design an efficient and durable anti-corrosion coating system. 【Content of invention】 [0003] The present invention provides a tower fo...
