Description

Technical Field

[0001] This utility model relates to the field of power supply conversion technology, and more specifically, to a ship cable line adapter. Background Technology

[0002] During port operations, vessels require power, but port operating areas are limited, and vessels often need to be moored side by side to meet loading and unloading needs. Due to the influence of strong winds and water current fluctuations in the port, the length of shore power cables must be strictly controlled to avoid the risk of being dragged and broken. This makes it difficult for distant vessels to directly obtain shore power from the dock. Therefore, it is necessary to install adapters. By installing adapters on nearby vessels, the shore power from the dock is connected to the nearby vessels, and then transmitted from the nearby vessels to the distant vessels.

[0003] However, in actual operation, the adapter still has the following problems: 1. Traditional adapters require manual connection of multiple cable interfaces, which is complicated and time-consuming, and the efficiency drops sharply in bad weather; 2. The conversion process involves plugging and unplugging high-voltage cables, which poses a safety hazard of arc discharge due to misoperation; 3. The adapter specifications are not fixed and cannot achieve fast conversion. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a ship cable line adapter, which aims to solve the problems mentioned in the background art.
