The invention relates to an impressed current cathodic protection device for a marine outboard cooling well. The device comprises a marine outboard cooling well and a constant potential rectifier, auxiliary anodes, an anode shielding layer and a reference electrode. The impressed current cathodic protection device is characterized in that each auxiliary anode mainly comprises an anode body, an insulating sheath and an anode base, wherein one end of the anode body is inserted into the insulating sheath, the insulating sheath is hermetically connected with the anode base, and the anode base is fixedly connected with the wall of the outboard cooling well. The two vertical auxiliary anodes are mounted on the surfaces of the two adjacent well walls respectively, so that two vertical auxiliary anodes are respectively positioned on the internal surfaces of the two adjacent well walls on the same layer between the two adjacent strengthening gussets. The impressed current cathodic protection device provided by the invention is used to protect the underwater part of an outboard cooler from sea water corrosion, and can effectively prevent corrosion of various parts of the outboard cooling well. The product has the characteristics of high reliability, distinct effect, low energy consumption and no environmental pollution, is simple in operation and maintenance, and the like.
Description
technical field [0001] The invention belongs to a marine cathodic protection system, in particular to an impressed current cathodic protection device for a marine outboard cooling well. Background technique [0002] Electrochemical corrosion of metal components in seawater has always been the main factor jeopardizing the safety of naval seawater systems. All steel surfaces exposed to seawater, based on various factors, such as uneven impurities in the steel, different stresses, uneven paint surfaces, and oxygen content in seawater, can cause steel corrosion and seriously threaten the safety of ships. In order to prevent the corrosion of steel in seawater, appropriate protective measures must be taken. There are two main types of anti-corrosion technology at present, one is coating, such as anti-rust paint and so on. The second is the ship's cathodic protection system. The two must be used in combination to effectively achieve the purpose of protection. Ship cathodic prote...
