Abstract

The invention relates to the technical field of ocean corrosion prevention, and provides a double corrosion prevention method for an ocean structure. The double corrosion prevention method comprises the following steps that a dual corrosion prevention system is provided, wherein the dual corrosion prevention system comprises a self-power-generation unit, a current conversion unit, a working electrode and a counter electrode; the self-power-generation unit is adopted to collect ocean mechanical energy and convert the ocean mechanical energy into alternating current electric energy, and the current conversion unit is adopted to convert the alternating current electric energy into direct current electric energy; the negative electrode end of the output voltage of the current conversion unit is connected with the working electrode; the working electrode is connected with the ocean structure; the positive electrode end of the output voltage of the current conversion unit is connected with the counter electrode; and the counter electrode is immersed in seawater to form a protection loop to protect the ocean structure.

Description

technical field [0001] The application belongs to the technical field of marine anticorrosion, and in particular relates to a double anticorrosion method for marine structures. Background technique [0002] The development of coastal cities plays an important role in my country's overall economic take-off, and the construction of infrastructure, especially marine facilities, is crucial to the economic development of the entire coastal city. Affected by the environment, the reinforced concrete used in the construction of marine facilities in coastal cities is vulnerable to the impact of waves and the erosion of seawater, causing corrosion of the internal steel bars, which seriously affects the durability of its structure. Therefore, it is of great economic significance to provide new and efficient anti-corrosion methods (metal anti-corrosion) for steel reinforcement materials in reinforced concrete structures. At present, people mainly use anti-corrosion coatings and cathodi...
