Ship shore-based power supply system adapting to water level changes

The utility model discloses a ship shore-based power supply system adapting to water level changes. The ship shore-based power supply system is arranged on the wharf boat; the system comprises: a system; the wharf boat comprises a high-voltage cable take-up and pay-off device, a high-voltage socket box, a transformer, a high-voltage power distribution cabinet and a low-voltage power distribution cabinet, one end of the high-voltage cable take-up and pay-off device can be connected with a shore-based incoming power supply, the other end of the high-voltage cable take-up and pay-off device is connected with a high-voltage incoming side of the high-voltage power distribution cabinet; the low-voltage power distribution cabinet is provided with a plurality of electrical intervals. The problem that ships berthed in a service area with large water level change in the Yangtze River basin get electricity from the shore is solved. The high-low voltage power supply and distribution system structure is optimized, the low
