Underwater power supply system
First Claim
1. An underwater power supply system that supplies electrical power underwater to one or a plurality of underwater moving bodies, the system comprising:
- an ascending/descending station that ascends and descends underwater between a water depth at which the underwater moving body works and the vicinity of the water surface, and has a rechargeable battery, a power-receiving coil and a power-supplying coil; and
a charging station that supplies electrical power wirelessly to the ascending/descending station in the vicinity of the water surface, wherein,at the water depth, the underwater moving body moves adjacent to the ascending/descending station, and electrical power is supplied wirelessly from the ascending/descending station to the underwater moving body.

a moving device by which the underwater moving body moves underwater,the charging station has;
a first power-supplying coil; and
a first power-supplying circuit that is connected to an external electrical power supply and drives the first power-supplying coil in a voltage/current waveform that is suitable for a wireless power supply, andthe ascending/descending station has;
a second rechargeable battery;
a second power-receiving coil;
a second power-supplying coil;
a power-reception/power-supply circuit that supplies electrical power from the second power-receiving coil to the second rechargeable battery, and that is connected to the second rechargeable battery and drives the second power-supplying coil in a voltage/current waveform that is suitable for a wireless power supply; and
an ascending/descending apparatus by which the ascending/descending station ascends and descends underwater. - View Dependent Claims (7, 8, 9)
