Degaussing cable trough, laying device for ship cable and cable laying method

Abstract

The invention provides a degaussing cable trough, a laying device for a ship cable and a cable laying method and relates to the technical field of cable laying. The degaussing cable trough comprises a cable trough body, a cover board and a cable fastening hook for fixing the cable, wherein the section of the cable trough body is rectangular and an opening is formed in the top; the cover board covers the opening in the top of the cable trough body; the cable fastening hook is internally arranged in the cable trough body and comprises a U-shaped bracket and two opposite and parallel lifting rods; the U-shaped bracket is formed by two vertical bars and a bottom bar; two grooves are formed in the inner side of each lifting rod and are correspondingly limited in the outer ends of the two vertical bars; and the two lifting rods are connected through a fastener. The laying device for the ship cable is formed by connecting a plurality of degaussing cable troughs and two adjacent degaussing cable troughs are connected through one sleeve. The cable laying method is implemented by adopting the laying device for the ship cable. The cable laying work of a constructor can be greatly facilitated through laying the cable in each cable trough body, and a scratched injury to the cable is reduced.

Description

Technical field [0001] The invention relates to the technical field of cable laying, in particular to a degaussing cable trough, a cable laying device for ships, and a cable laying method. Background technique [0002] When the degaussing cable is arranged below the waterline and in the liquid tank, engine room, power station, etc., it must be effectively protected to prevent damage to the degaussing cable and destroy the degaussing system. In the construction of surface ships, the form of cable tube is generally used to protect the degaussing cable in China, that is, the degaussing cable tube is installed at the above-mentioned position, and the degaussing cable is laid and installed in the tube. Since the degaussing cable will pass through almost all the watertight next walls, in order to support the overall anti-sinking performance of the whole ship, after the degaussing cable is laid, it is necessary to fill the nozzle of the cable tube with sealing filler. In the actual con...

Problems solved by technology

Since the degaussing cable is spread over the entire outline of the ship, increasing the degaussing cable duct may increase the opening on the hull structure, which will cause serious damage to the hull structure

[0005] The overall airtightness of the degaussing cable pipeline is difficult to guarantee. Since the degaussing cable of the whole ship is divided into multi-winding cables, each set of windings may intersect in some places and change the laying direction. The degaussing cable pipeline is generally installed with a conversion box in these places. form to lay the windings of each cross

In the process of ship construction, the sealing of a single cable tube is relatively easy to achieve, but the means to ensure the sealing of the conversion box are limited, and the conversion box and cable tube are generally arranged in the bilge of the cabin, which will be contaminated by oil, water and other liquids. Long-term immersion and corrosion, it is difficult to ensure that the seal of the conversion box has the same life as the whole ship. In the case where the overall seal of the degaussing cable pipeline of the whole ship is difficult to guarantee, the anti-sinking performance and vitality of the whole ship will have a greater risk
