Offshore wind power sacrificial anode protection process

Abstract

The invention discloses an offshore wind power sacrificial anode protection process which comprises the following steps that firstly, a steel pipe pile is divided into an atmosphere area, a tidal range area, a total immersion area and an under-mud area according to the actual situation; then the sum of the area of the atmosphere area and the tidal range area is calculated, the outer side of the steel pipe pile within the range of the atmosphere area and the tidal range area is coated with mineral anti-corrosion paste, and the outer side of the mineral anti-corrosion paste is coated with a mineral anti-corrosion belt after coating is completed. The steel pipe pile is divided into the atmosphere area, the tidal range area, the total immersion area and the under-mud area, coating anti-corrosion operation is carried out in the range of the atmosphere area and the tidal range area, corrosion of corrosive media to a steel structure can be effectively prevented, meanwhile, seawater can be isolated, mechanical damage can be resisted, and sacrificial anodes are protected by calculating the using amount of sacrificial anodes in the total immersion area and the under-mud area according to the actual situation, so that corrosion of the steel pipe pile can be effectively inhibited, meanwhile, the protection effect is stable and reliable, and maintenance and management by a specially-assigned person are not needed.

Description

technical field [0001] The invention belongs to the field of protection technology, in particular to an offshore wind power sacrificial anode protection technology. Background technique [0002] In existing life, steel pipe piles are often installed on wind turbine platforms in shallow water areas of offshore wind power, and most of the existing steel pipe piles are fixed steel structures. The corrosion areas in the lower area and the mud area are exposed without coating, which seriously threatens the safe operation and long-term use of steel pipe piles. Therefore, timely and effective cathodic protection for steel pipe piles is very necessary. Invention content: [0003] The object of the present invention is to provide an offshore wind power sacrificial anode protection process to solve the above problems, which solves the problems mentioned in the background technology. [0004] In order to solve the above problems, the present invention provides a technical solution: ...
