Abstract
Proposed are a submarine power supply system and power supply method using a seawater battery, the system having a chargeable/dischargeable battery that is arranged on the outside of a pressure hull, so as to use, as a cathode, sodium ions dissolved in seawater, and thus produce electric power, which is then used as electric power required for operating a submarine.
Claims4
A submarine power supply system using a seawater battery, the system comprising:
- an anode array formed of at least one anode line comprising a plurality of anodes disposed at a predetermined interval along a longitudinal direction of an outer side surface of a pressure hull between an outer hull and the pressure hull of a submarine;
- a cleaning means configured to move along a longitudinal direction of the anode array between the outer hull and the pressure hull, thereby cleaning foreign substances attached to the anode array;
- and
- a pair of guide rails provided along both side end portions of the anode array, the pair of guide rails guiding the cleaning means to be capable of being moved along the longitudinal direction of the anode array,
- wherein, as the anode array is formed such that seawater introduced through a space between the outer hull and the pressure hull is in contact with the anode array, electric power generated by sodium ions accumulated according to a contact between the seawater and the at least one anode line is gathered, thereby providing the electric power as electric power required for propelling the submarine.
A submarine power supply method of a submarine power supply system using a seawater battery, the method comprising:
- a contacting process in which seawater introduced through a space between an outer hull and a pressure hull of a submarine is in contact with an anode array that is formed of at least one anode line disposed at a predetermined interval along a longitudinal direction of an outer side surface of the pressure hull between the outer hull and the pressure hull;
- and
- a supplying process in which electric power is generated as the seawater and the at least one anode line are in contact with each other and sodium ions are accumulated, and a generated electric power is gathered and then is provided as electric power required for propelling the submarine,
- wherein the system comprises:
- the anode array;
- a cleaning means configured to move along a longitudinal direction of the anode array between the outer hull and the pressure hull, thereby cleaning foreign substances attached to the anode array;
- and
- a pair of guide rails provided along both side end portions of the anode array, the pair of guide rails guiding the cleaning means to be capable of being moved along the longitudinal direction of the anode array.
