Description

Technical Field

[0001] The utility model belongs to the technical field of ship cables, in particular to a ship light anti-interference cable. Background Art

[0002] Marine light anti-interference cable is a cable with specific performance and purpose. It is mainly used for power supply and communication transmission of ships. This cable can effectively prevent the influence of external electromagnetic interference and noise on the ship's power system, ensuring the stable and reliable operation of the system.

[0003] At present, it is found in the actual application of existing marine cables that due to the use environment on the water or sea surface, the cables are inevitably in contact with water for a long time, which causes the microorganisms in the water to adsorb the cables, accelerates their aging, and easily causes short circuits inside the cables, which is not conducive to the stable use of the cables on the water surface;

[0004] In order to solve the above problems, the present application proposes a ship-use lightweight anti-interference cable. Utility Model Content

[0005] The utility model aims to provide a light-weight anti-interference cable for ships, which solves the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a light anti-interference cable for ships, comprising: a cable, the interior of which is braided with copper wires to enhance its anti-interference capability; a telescopic ring is arranged on the outside of the cable, one side of the telescopic ring is arranged with an outer folding tube for protecting the cable from being corroded by microorganisms in water, and an elastic rope for controlling the installation tension state is arranged on the outside of the telescopic ring; a convex ring for installing the outer folding tube is arranged on one side of the telescopic ring, and an inner folding tube is arranged on the inner side of the outer folding tube, and an air cavity filled with gas to increase buoyancy is formed between the two.

[0008] Furthermore, a transfer shaft is provided at the end of the elastic cord, and a positioning groove for installing the elastic cord is provided on the outer side of the telescopic ring.

[0009] Furthermore, a blocking pad is provided on the inner side of the telescopic ring to press against the cable to fill the gap and form a seal.

[0010] Furthermore, adapter blocks are provided at both ends of the adapter shaft to form a rotational connection with the limiting grooves at both ends of the elastic rope.

[0011] Furthermore, a protruding screw is provided on one side of the adapter block, and screw holes for connecting the screw are provided at both ends of the adapter shaft.

[0012] Furthermore, a positioning hole for filling the tube with gas is provided inside the upper end of the convex ring.

[0013] Furthermore, a convex tube and a sealing cover mechanism are provided at the upper end of the positioning hole.

[0014] The utility model has the following beneficial effects:

[0015] The utility model adjusts the use length by stretching the outer folding tube and then rotates the adapter block to drive the elastic rope to lock the telescopic ring so that the blocking pad is tightly pressed against the surface of the cable to form a seal, which can effectively prevent water from entering the interior and affecting the cable, while ensuring its use stability and avoiding the erosion of microorganisms in the water, so as to extend the service life and environmental adaptability of the marine cable.

[0016] The utility model can increase the occupied space of the air cavity by stretching the outer folding tube, and then fill air through the positioning hole to make the air cavity exert buoyancy on the cable. When the cable falls into the water, it can automatically float, forming a slowing effect on the sinking and preventing the joint part from entering the water, thereby ensuring the safety of the cable and preventing the cable from directly sinking, which is convenient for salvage.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-4 As shown, the utility model is a light anti-interference cable for ships, comprising: a cable 1, the interior of which is braided with copper wires to enhance its anti-interference ability;

[0028] A telescopic ring 2 is arranged on the outside of the cable 1, an outer folding tube 3 is arranged on one side of the telescopic ring 2 to protect the cable 1 from being corroded by microorganisms in water, and an elastic rope 4 for controlling the installation tension state is arranged on the outside of the telescopic ring 2;

[0029] A convex ring 5 for mounting an outer folding tube 3 is provided on one side of the telescopic ring 2, and an inner folding tube 9 is provided on the inner side of the outer folding tube 3, and an air cavity 14 filled with gas to increase buoyancy is formed between the two;

[0030] The present embodiment provides an automatically floating marine cable 1. The protection of the outer folding tube 3 can effectively prevent the cable 1 from being corroded by microorganisms in the water, thereby ensuring the service life and stability of the cable 1. After the outer folding tube 3 is stretched, gas can be filled inside to allow the cable 1 to automatically float when it falls into the water, making it easy to salvage.

[0031] Among them, a transfer shaft 6 is provided at the end of the elastic cord 4, and a positioning groove 7 for installing the elastic cord 4 is opened on the outer side of the telescopic ring 2. The positioning groove 7 adopts a spiral staggered structure to prevent the elastic cord 4 from being dislocated and knotted.

[0032] The inner side of the expansion ring 2 is provided with a blocking pad 8 which abuts against the cable 1 to fill the gap and form a seal, so as to prevent water from entering.

[0033] Wherein, adapter blocks 10 are provided at both ends of the adapter shaft 6, which are rotationally connected with the limiting grooves 12 at both ends of the elastic rope 4, and a protruding T-shaped ring body mechanism is provided on the outer side of the adapter block 10.

[0034] A protruding screw rod 11 is provided on one side of the adapter block 10 , and screw holes 13 for connecting the screw rod 11 are provided at both ends of the adapter shaft 6 .

[0035] A positioning hole 15 for filling gas is provided inside the upper end of the convex ring 5 .

[0036] Among them, the upper end of the positioning hole 15 is provided with a convex tube and a sealing cover mechanism. When the outer folding tube 3 and the inner folding tube 9 are stretched to obtain insufficient gas, filling can be carried out through the convex tube mechanism.

[0037] It can be understood that the utility model can effectively prevent the microorganisms in the water from corroding the cable 1, so that it can maintain long-term stable performance. At the same time, it can also automatically float and slow down the falling of the cable 1 when it falls into the water, so as to facilitate salvage and recovery.

[0038] A specific application of the operation process of this embodiment is as follows: when in use, first, the telescopic ring 2 and the outer folding tube 3 are sleeved on the outside of the cable 1, and then the placement area is adjusted according to its use position and the outer folding tube 3 is stretched to increase the coverage range. At the same time, the inner folding tube 9 is driven to expand to increase the use space of the air cavity 14, and then the elastic rope 4 is wrapped around the outside of the positioning groove 7 and the screw 11 is screwed and installed inside the screw hole 13. The telescopic ring 2 can be pressed so that the blocking pad 8 is tightly pressed against the outer surface of the cable 1 to fill the gap and form a seal. At this time, air can be injected into the air cavity 14 through the positioning hole 15 to increase its buoyancy. At this time, the cable 1 can effectively prevent erosion by microorganisms in the water and avoid accelerated aging of the outer skin. At the same time, it can also automatically float when it falls into the water, forming a resistance to the falling force when falling, preventing the cable 1 from sinking, and facilitating salvage.
