Description

Technical Field

[0001] The invention relates to the technical field of ICCP anti-corrosion equipment, in particular to an ICCP anti-corrosion equipment installation structure for oil tankers. Background Art

[0002] The ICCP system is a device that protects the steel surface of the hull from water corrosion, so all ships will be equipped with this device. Conventional bulk carriers will arrange the ICCP system at the stern or bow and stern according to the area to be protected (including the propeller area, rudder protection area and underwater hull protection area). On oil tankers, because the cargo hold area and the bow empty compartment are both dangerous areas, explosion-proof requirements must be considered when arranging the ICCP system at the bow.

[0003] Currently, few ICCP system manufacturers can provide explosion-proof equipment, and the cost of explosion-proof equipment is relatively high compared to ordinary equipment. We have designed a solution for arranging ICCP systems in hazardous areas: an independent sealed space is designed in the structure to install the electrodes of ordinary ICCP systems. Through this design method, the installation requirements of explosion-proof equipment can be avoided, and installation and maintenance are also very convenient.

[0004] In the ICCP system of oil tankers, the anode is powered by a constant potential meter to achieve corrosion protection for the bottom of the hull. However, the anode is placed in the bow empty compartment. The constant potential meter is limited in adjusting the power supply to the anode. As a result, it cannot provide enough current for the larger area of ​​the bottom of the hull, which limits the protection surface of the bottom hull of the oil tanker and the protection range. In addition, the sealing between the anode and the reference electrode in the empty compartment cannot be guaranteed, which greatly reduces the corrosion resistance of the hull. Summary of the invention

[0005] The object of the present invention is to provide an installation structure of ICCP anti-corrosion equipment for oil tankers, which can adjust the current of appropriate size to the larger area of ​​the hull at the bottom of the oil tanker, thereby ensuring that the bottom hull of the oil tanker can be fully protected, and the anode and the reference electrode can be sealed and protected, thereby improving the stability of the anti-corrosion equipment.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an installation structure of ICCP anti-corrosion equipment for oil tankers, comprising a first sealed box, a second sealed box, an anode, and a reference electrode, wherein a first sealed cover is sealedly installed on the top of the first sealed box, and a hand hole cover is detachably installed in the middle of the first sealed cover, the anode comprises an electrical connection column fixedly installed at the bottom of the inner wall of the first sealed box, a first contact block is fixedly installed at an equal interval on the top of the electrical connection column, mounting blocks are fixedly installed on the side walls of the first sealed box respectively, a shaft rod is fixedly installed between the two groups of the mounting blocks, electrical connection plates are fixedly sleeved at equal intervals on the outside of the shaft rod, an electromagnet is fixedly installed on one side of the electrical connection plate, a magnet block is fixedly installed on the top of the electrical connection plate, electrical connection wires and a sliding sleeve are movably sleeved on the outside of the shaft rod, and a second contact block is fixedly installed on the bottom of the sliding sleeve.
