Submarine cables are buried in the submarine surface, which is applied to the deep sea area, and after trenching, to the coastal low deep sea area.

The construction of cables in coastal deep-sea areas where cables and protective materials are installed after the excavation of the sea floor by a trench for a certain depth or more is carried out by using stones or stones is very vulnerable to external shocks caused by shellfishes or general fishing vessels Therefore, it is very important not only to back up enough depths but also to manage aftermath.

After the submarine cable is installed, it is often difficult to manage the submarine cable because the cable is exposed and the location is shifted due to the loss of the soil around the cable due to the strong waves during fast tidal currents and typhoons. come.

For example, Korean Patent Publication No. 10-2013-0039967 discloses a technique in which a light sensor and a GPS position recognizer are embedded in a cable or a cable protection tube at a predetermined depth, When the surveillance terminal is exposed to the water because the backfill material on the cable is lost due to the current, the light sensor senses sunlight transmitted through the water and the switch is turned on, And transmits the position information on the GPS provided by the GPS position recognizing unit to the alarm signal transmitting unit and the alarm signal transmitting unit transmits the alarm signal to the alarm signal monitoring unit based on the wired / .

In this case, however, it is difficult to supply power to the monitoring terminal by the sunlight in the deep sea, and it is difficult to maintain the charged state by the natural discharge in the case of the battery.

Hereinafter, a submarine cable position transceiver according to an embodiment of the present invention will be described with reference to FIGS. 1 to 5. FIG.

1, a submarine cable position transceiver according to an embodiment of the present invention includes a cathode 210 having one end exposed to seawater to cause a reduction reaction, and a cathode 220 having one end exposed to seawater to generate an oxidation reaction ), And it is attached to the submarine cable and transmits / receives location information to the outside.

Here, the anode 210 uses either a carbon rod, silver chloride, or copper.

That is, the transceiver 100 can supply power to the transceiver 100 by using saline contained in seawater as an electrolyte, performing a reduction reaction with the anode 210, and an oxidation reaction with the cathode 220.

At this time, as the anode 210, copper, a carbon rod, silver chloride, or copper may be used. In the case of copper, a crack may occur, and a carbon rod may be mainly used.

On the other hand, as the cathode 220, zinc, magnesium, or aluminum can be used, and the volume is increased due to the density change due to the oxidation reaction.

At this time, the cathode 220 may coat the outer surface of the cathode 220 to slow down the oxidation reaction. In order to prevent the coating from being unstable due to the coating breakage due to the change in volume caused by the oxidation reaction of the cathode 220, the coating may be sequentially broken at one end, or the metal of the cathode 220 It can also be used in foam form so as not to affect the coating.

2 is a block diagram showing the transmission / reception device 100 of FIG. 1 in detail.

2, the transceiver 100 includes a power source 200 having an anode 210 and a cathode 220 to supply power to the transceiver 100, a communication unit for transmitting and receiving information to and from the outside And a control unit 400 that receives power from the power supply unit 200 and controls transmission and reception of the communication unit 300.

The transceiver 100 may further include a magnetic marker unit 500 for indicating the position of the transceiver 100 using a magnetic body.

That is, the transmitting / receiving device 100 can receive the power from the power source 200 and communicate the location information of the transmitting / receiving device 100 and various information of the submarine cable installed in the transmitting / receiving device 100 to the outside.

Meanwhile, the power supply unit 200 may periodically supply power to the communication unit 300 and the control unit 400 only when the charging of the power supply unit 200 exceeds a predetermined value.

The power supply unit 200 may further include a monitoring electrode 240 to be described later on the cathode 220 to allow the control unit 400 to detect the degree of oxidation of the cathode 220 to improve the lifetime of the transmission / Can be monitored remotely.

3 is a diagram showing the cathode 220 of FIG. 2 in more detail.

3, the power supply unit 200 includes an anode 210 that makes contact with sea water to cause a reduction reaction, a cathode 220 that causes an oxidation reaction in contact with seawater, and a cathode 220, And a coating film 230 for exposing the coating film 230 to the substrate.

The coating layer 230 includes a bent portion 231 on which the cathode 220 can bend and break when the volume of the cathode 220 increases due to the oxidation reaction.

In addition, the coating film 230 uses any one of enamel, epoxy, paint, coole tar, or PVD as the coating material on the outer surface of the power source unit 200.

Here, the coating film 230 is formed by plating, cladding, or vapor deposition of a metal having high corrosion resistance on the outer surface of the cathode 220.

That is, by using the cathode 220 as a foaming metal, the expansion of the cathode 220 occurs inside the cathode 220 and the overall volume expansion can be suppressed, so that it is necessary to provide the bending portion 231 in the coating film 230 And the coating film 230 can be maintained for a long period of time.

The coating film 230 is plated, cladded or deposited on the outer surface of the cathode 220 by using a metal having a high corrosion resistance so that the coating film 230 is separated from the cathode 220 even when the coating film 230 is exposed to seawater for a long time And the cathode 220 can be protected.

That is, the monitoring electrodes 240 are provided at regular intervals along the cathode 220, and may be provided with a cathode 220 and a constant air layer. At this time, the surveillance electrode 240 is not in direct contact with the seawater, so electricity is not supplied. However, when corrosion of the cathode 220 proceeds and the seawater contacts the surveillance electrode 240, power is supplied to the surveillance electrode 240 And the control unit 400 can detect this.

The control unit 400 can detect the degree of corrosion of the cathode 220 according to the position of the monitoring electrode 240 to which the power is applied by the seawater and can detect the corrosion state of the cathode 220 through the communication unit 300, It is possible to externally predict the service life of the transmission / reception device 100 by transmitting the information.
