Problems solved by technology

Existing electrolytic seawater antifouling devices are relatively fixed and cannot be applied to steel pile antifouling with multiple structures or irregular structures
However, the electrolytic copper-aluminum antifouling technology is not suitable for large processing capacity, occupies a large area, has little impact on slime organisms and plants, and has high water quality requirements

Abstract

The invention provides an ocean steel structure electrolysis antifouling device, which comprises a power supply cabinet, a flexible rope-shaped electrode and an ocean steel structure, and is characterized in that the rope-shaped electrode is wound on the ocean steel structure; the rope-shaped electrode comprises an anode, a cathode and a hollow shell, the anode and the cathode are arranged in the shell at an interval, the anode and the cathode are oppositely arranged in the shell, the anode and the cathode are electrically connected with the power supply cabinet, and a through hole for seawater to enter the shell is formed in the shell; the rope-shaped electrode is used for electrolyzing seawater so as to generate available chlorine in the seawater near the marine steel structure, so that the marine steel structure is subjected to antifouling treatment.

Description

technical field [0001] The invention relates to the technical field of marine equipment anti-fouling, in particular to an electrolytic anti-fouling device for marine steel structures. Background technique [0002] The steel structure foundation of offshore wind farms is subject to the attachment and corrosion of various marine organisms, including marine animals, shellfish, and algae. This greatly affects the safe operation and service life of offshore wind turbines. Therefore, the construction of offshore wind farms puts forward higher requirements for the anti-fouling technology of basic steel structures. The steel structure of the wind farm in Shanghai suffers from serious biological growth and large damage to the coating, making it difficult to repair on site and guaranteeing the quality. At the same time, the damage to the coating leads to the problems of large consumption of sacrificial anode blocks and large positive shift of cathodic protection potential, which is fa...
