Method for laying power supply cable of ship shore power system for 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 invention belongs to the technical field of ship shore power, and relates to a method for laying a power supply cable suitable for a ship shore power system with water level drop. Background technique [0002] At present, docks along rivers, lakes or islands are usually provided with platforms for ships to dock for supplies, float in the water, and berth on the shore, also known as barges. It is a rectangular flat-bottomed boat without a power device, and its power source is provided by the power supply system on the shore. At present, most of the power supply cables of the shore power system are laid in a wave shape along with the overhead steel strands; The water level fluctuates and the winch automatically retracts and unwinds the steel strand. The problems of laying the shore power system cable by this method are: [0003] The cables are overhead, and overhead support needs to be built, which is costly; [0004] Cables are overhead, install...

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
