Applicable to the laying method of power supply cables for shore power system of ships with water level drop

Abstract

A Method for laying power supply cable of ship shore power system for water level drop is provided. The cable bridge is arranged along the inclined bank, the cable net jacket is arranged through the cable connected with one end of the barge power receiving equipment and connected with the tension sensor, and the barge is connected through the tension sensor. When the barge changes with the water level, the control equipment controls to start the cable winch to shrink or release the cable. The cable bridge is arranged along the inclined bank, and the cable net jacket is connected with the tension sensor. The Method for laying power supply cable of ship shore power system for water level drop overcomes the problems of high cable laying cost, low cable life and potential safety hazard of theoriginal ship shore power system. The method has the advantages of low construction cost, no need of high-altitude operation, precise control of cable shrinkage and release amount, long service life,safety and reliability.

Description

Technical field [0001] The present invention belongs to the technical field of ships shore power, relates to a method suitable for system level drop ship shore power supply cable laying. Background technique [0002] Currently, along the river, lake or the island pier, there is usually set the platform for the use of ships docked supplies, floating in the water, docked at the shore, also known as barges. It is a non-powered barge rectangular device, which is the source of power provided by the shore power system. Currently, most of the shore power supply system with the overhead cable strand laying undulating shape; laying the need to erect the gantry propped across the strand path, disposed side strand-like barge winch, with water level fluctuation automatic retractable steel cable winch. The method of laying the presence of the ship shore power cable system is the problem: [0003] Overhead cable, overhead need to build support, high cost; [0004] Overhead cables, installation...

AI Technical Summary

Problems solved by technology

[0003] The cables are overhead, and overhead support needs to be built, which is costly;

[0004] Cables are overhead, installation and maintenance are inconvenient, and there are potential safety hazards in high-altitude operations;

[0005] When the cable is retracted and retracted in the fluctuation of water level, it will frequently rub against the steel wire strands, and the frequency of cable folding is too high, which will affect the service life;

[0006] The overhead cables are located in the wind direction area with water, and the wind force is erratic, which requires high stability of the overall transmission structure. In the case of sudden strong winds, it is difficult to control the retraction and release between the barge, the cable and the steel strand, and it is easy to cause the barge to capsize ,There are security risks
