Power connection protective device for battery service ship

The invention relates to a power connection protective device for a battery service ship. The power connection protective device comprises a main ship body and the battery service ship. The main shipbody is provided with a power connection output head. The battery service ship is provided with a power connection output base. A protective body is arranged between the power connection output head and the power connection output base. The protective body telescopically extends from the power connection output head to the position of the power connection output base and the protective body is used for shielding rainwater when the power connection output head and the power connection output base are butted. The situation of water seepage due to the climate or the fluctuation of the navigationwater plane during the power connection can be avoided so as to better protect the power connection performance of the main ship body and the battery service ship and protect the safety performance ofthe battery service ship i
