In recent years, in order to reduce environmental pollution, various countries in the world change the conventional diesel-powered ship technology of various ports into electric power. Each port worldwide has established a shore-based power plant or shore-based vessel to power a ship that is berthed on shore. However, this technique operates in a number of technical disadvantages. For example, in a process of charging a ship which is parked on the shore, a plug on the ship is often manually inserted into a shore power facility to supply power to the ship. As is well known, the charging cable of a ship is very heavy and not easy to plug, a great deal of manpower resources are consumed in the operation of charging the ship, and if the cable is damaged, the personal safety is threatened.
In addition, an emergency situation often occurs in the operation of charging the ship. If the ship starts to run when the charging plug is not pulled out after the ship is charged or the charging is completed, the charging cable pulls the shore power plug, which can cause damage to the socket of the shore power box and cause the situation that the whole shore power equipment is in electric leakage, short circuit and the like, which can cause serious threat to personnel safety or equipment operation and has hidden danger of serious safety accidents.
