Background

The offshore wind power installation platform needs to use a steel frame base as a foundation, and the marine environment is a complex corrosion environment relative to the steel frame foundation, including chemical corrosion, physical erosion corrosion, biological corrosion and the like, wherein the chemical corrosion is dominant. Typically, cathodic protection is used to electrochemically protect a steel frame base, on which a plurality of sacrificial anodes are distributed. However, the sacrificial anode is likely to loosen due to strong vibration in the steel frame installation and piling processes, so that the sacrificial anode is installed by adopting an underwater welding method under partial working conditions. In the process of installing the sacrificial anode, because the sacrificial anode is heavier, the adjustment of a common sacrificial anode in the processes of hoisting, positioning and welding is inconvenient, the welding efficiency is lower, and meanwhile, in order to ensure that the sacrificial anode is firmly connected with the steel frame base, the depth of a welding line is generally larger, welding spots are more, and the influence on the foundation structure of the steel frame base is larger.
