Description

Technical Field

[0001] The utility model generally relates to the technical field of ships, and particularly relates to a ship with a shore power cable guiding and conveying device. Background Technique

[0002] A ship is equipped with a shore power cable. When the ship is docked, the ship is connected to a power source on the shore through the shore power cable to realize shore power supply to the ship. The shore power cable on the ship is wound on a cable winch. When shore power needs to be connected, the shore workers at a lower position pull the cable to the shore power source and then connect the shore power cable connector to the shore power source. In order to reduce the wear between the shore power cable and the hull, a shore power cable guiding and conveying device is configured on the ship deck. The Chinese patent (authorization announcement number: CN207200240U) discloses a marine cable support and guiding device, which includes a fixed seat and a rolling support frame that can rotate relative to the fixed seat. The fixed support frame includes two swing arm plates and a plurality of fixed rollers arranged between the two swing arm plates. The rolling support frame switches between vertical and horizontal positions to reduce the floor area during normal times. When the rolling support frame is in the horizontal position, the cable is supported by the fixed rollers, reducing the friction problem during dragging. The above-mentioned existing marine cable support and guiding device is installed on the ship deck. When in use (i.e., when the rolling support frame is in the horizontal position), the plurality of fixed rollers are arranged close to the horizontal.

[0003] However, the above-mentioned marine cable support and guiding device has the following problems:

[0004] 1. After connecting to the shore power, the part of the shore power cable that extends out of the marine cable support and guiding device and is suspended will swing significantly under the drive of the sea breeze and the swaying ship, increasing the risk of the shore power cable breaking away from the last fixed roller;

[0005] 2. After connecting to the shore power, the shore power cable will bend downward outside the last fixed roller under the action of gravity and the bending degree is relatively large, increasing the risk of damage to the shore power cable. Summary of the Utility Model
