ANODE POLE AND IDENTIFICATION SYSTEM OF ANODE POLE FOR MARINE STRUCTURE}

The present invention relates to an electrode installed in the marine structure in order to prevent marine organisms from engrafting in the marine structure or to prevent corrosion of the marine structure. The present invention relates to an identification device for the electrode in order to maintain the quality of the electrode. The present invention relates to an electrode identification system of an offshore structure and an electrode thereof.

A large amount of seawater is introduced as cooling water for cooling devices such as desalination plants, seawater magnesia manufacturing plants, and power plants.However, due to the inflow of seawater, spores such as mussels, barnacles, and sea horses attach to and grow in the pipeline. There is a problem. In addition, surfaces such as pipelines react with seawater to generate corrosion.

This problem not only occurs in land-based plants, but also occurs in ships and the like. In other words, the vessel is required to supply seawater for cooling the engine and balancing the vessel (Ballast), the same problem occurs in the area where the seawater is supplied.

In order to solve this problem, the prior art uses the anti-fouling electrode and the anti-corrosion electrode together to prevent the contamination of the structure by marine natives while preventing the contamination of the structure by corrosion.

As a conventional technology related to the present invention, Korean Patent Application Publication No. 2001-0097221 "A marine life habitat prevention apparatus and method thereof", Korean Utility Model Registration No. 249437 "Preventing attachment of marine organisms Device "and the like.

According to the prior art, copper (Cu) is mainly used as an antifouling electrode, and aluminum (Al), iron (Fe), etc. are used as an electrode for corrosion prevention.

In addition, the anticorrosive electrode is known to have a certain antifouling effect as well as the anticorrosive effect, and is generally used together with the antifouling electrode.

1 and 2 are schematic diagrams of a conventional antifouling and anticorrosion system.

1 is a seawater is introduced into the tank, and equipped with a pair of anti-fouling rods for releasing copper ions and a positive electrode rod for releasing aluminum or iron ions, the anode rod for antifouling and anti-corrosion rods receiving AC power A constant current automatic rectifier for supplying DC power is connected to the anti-fouling anode rod and the anti-corrosion anode rod.

FIG. 2 relates to an antifouling and anticorrosion system for seawater flowing into a cooling water into a vessel, and is basically a technology having the same identity as that of FIG. 1.

According to these conventional techniques, an antifouling anode rod and an anticorrosion anode rod are used while contacting with seawater, and an antifouling anode rod and an anticorrosion anode rod are coupled to a fixed part and fixedly coupled to an offshore structure such as a hull and a tank.

On the other hand, anode rods, fixtures, and power supplies (eg, constant current automatic rectifiers) are directly related to the quality of antifouling and anticorrosive systems, so they are all manufactured directly by one manufacturer. As a result of the release, they should be replaced approximately every two years.

When the anode rod is replaced as described above, the new anode rod to be replaced is often manufactured and supplied by a different manufacturer than the original supplier of the antifouling and anticorrosive system.

However, if third-party anode rods are used in antifouling and anticorrosion systems, manufacturers of the original antifouling and anticorrosion systems will find it difficult to maintain the same quality of their products, and this impairment of the quality of the products will affect the credit in the market. There is a risk of massive damage.

Therefore, the present invention is to maintain the independence of the other company to the electrode by providing an identification mark on the electrode, and by providing an identification device for identifying the identification mark on the fixed part to which the electrode is fixed.

The controller 700 transmits a signal for controlling the power supply of the power supply unit 600 to the power supply unit 600 according to the signal transmitted from the wireless identification readers 520a and 520b.

That is, only when the electrode 300 read by the wireless identification readers 520a and 520b is genuine, the power supply unit 600 supplies power to the electrode 300, and by the wireless identification readers 520a and 520b. When the read electrode 300 is produced by another company, the power supply unit 600 does not supply power to the electrode 300.

In addition, even when the electrode 300 read by the wireless identification readers 520a and 520b is a genuine product, when the electrode 300 is used for a predetermined period, the power supply unit 600 does not supply power to the electrode 300. Do not That is, the same radio identification tag may not be used for a certain period of time, for example, two years or more. For this operation, the controller 700 not only receives information on the authenticity of the electrode 300 from the wireless identification readers 520a and 520b, but also the controller 700 from the time when the electrode 300 is first used. It is configured to determine how long the period has passed.
