As shown in FIG. 1 , in the embodiment, a ship charging method according to the present invention comprises the following steps:

Step S10, connecting one ends of the plurality of cables 2 to the charging device respectively;

Step S20, pulling one end of each of the cables 2 away from the charging device to the step bridge 1;

Step S30, when the ship to be charged reaches the parking position of the water surface, the cable 2 is pulled to the ship through the step bridge 1 and connected to the charging socket.

Step S40: After the charging is completed, the cable 2 is disconnected from the charging socket of the ship.

The ship is charged by connecting the cable 2 to the ship to be charged, and the design can directly charge the battery in the ship without burning diesel fuel for power generation, thereby reducing the use of the diesel engine of the ship and avoiding the process of burning the diesel oil. The exhaust gas generated in the environment pollutes the environment. Wherein, the cable 2 is pulled into the step bridge 1 so that the cable 2 is fixedly mounted on the step bridge 1 in advance. When the ship needs to be charged, the step bridge 1 is adjusted so that the step bridge 1 approaches the ship and is opposite to the ship to be charged. When the cable 2 is pulled along with the step bridge 1 to the ship, the ship is charged, so that the cable 2 can be pulled to the ship to be charged, and the cable 2 is not required to be manually charged each time the ship is charged. Re-apply the ship to be charged from the charging device to prevent the cable 2 from being shaken or dropped into the water due to the influence of the surface wave, posing a safety hazard. When charging is complete, unplug the cable 2 from the ship's charging outlet. Specifically, the charging device can be placed on the shore or on a ship dedicated to charging.

In actual use, the total length of the cable 2 is determined according to the distance between the charging device and the vessel to be charged, and in view of the wave compensation, an appropriate margin is reserved on the cable 2 for wave compensation.

In the step S20, a cable winch 7 for winding the cable 2 is arranged between the charging device and the step bridge 1. The cable 2 is wound by the cable winch 7 and the length of the cable 2 is adjusted according to the distance between the charging device and the charging socket in actual use, so as to avoid the excessive length of the cable 2 Fall into the water or avoid accidental pulling of the cable 2 by the construction personnel during the construction process to ensure the safety of the cable 2 and improve the alignment of the cable 2. Specifically, the cable winch 7 is powered by a charging device.

In order to make the charging device charge a plurality of ships at the same time, the number of cables 2 plugged into the charging device is larger than the number of charging plugs on the ship, and the design can fully utilize the charging device to charge the ship and improve the utilization of the charging device. Rate, reducing the manufacturing cost of the ship.

In the present embodiment, the cable winch 7 includes a plurality of cable drums, and the cable drums are disposed corresponding to the respective cables 2.
