Description

Marine ratproof cable

Technical Field

The invention belongs to the technical field of cables, and particularly relates to a rat-proof cable for a ship.

Background

The rat damage in the daily use of the marine cable is extremely painful for people, and two methods are generally used for rat prevention: 1. a thicker metal layer is wrapped outside the cable, and the metal layer is high temperature resistant and mouse bite resistant; 2. the cable is manufactured by adding capsaicin or other stimulating materials into an insulating layer and a sheath material, and the strong pungent taste of the capsaicin is utilized, so that the oral mucosa and gustatory nerves of the murine are strongly stimulated to abandon chewing, and the rat leaves immediately.

However, the first method is high in cost, and can increase the weight and reduce the flexibility of the cable, so that the cable is not easy to lay; by using the second method, after the cable is bitten by a mouse, the bitten local capsaicin can lose the smell in the air, the mouse likes to stare at the same place to bite, and the cable is bitten by the mouse in such a reciprocating way.

Meanwhile, the place where the mouse gnaws is often hidden and not easy to find, and the cable bitten needs to be replaced in the whole section, so that the cost is high. Therefore, the marine cable capable of overcoming the defects is designed, and has a wide market prospect.

Disclosure of Invention

In order to meet the requirements, the invention provides the marine ratproof cable which not only has an excellent ratproof function, but also is easy to find after being bitten by a rat and damaged so as to remind workers of overhauling.

The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a marine protection against rodents cable, includes the cable core, the cable core is formed by a plurality of wires and the transposition of poly-p-benzamide fibre, the wire structure is: the innermost layer is a copper core, a fluoroplastic layer is arranged outside the copper core, and an aluminum foil layer is arranged outside the fluoroplastic layer;

a quartz glass fiber cloth layer is arranged outside the cable core, a radiation crosslinking polyolefin sheath is arranged outside the quartz glass fiber cloth layer, and a plurality of rat-proof sleeves are arranged outside the radiation crosslinking polyolefin sheath;

the structure of the rat-proof sleeve is as follows: the inlayer is for blocking water yarn and nylon wire and thoughtlessly compile the layer, it scribbles deliquescent substance, capsaicin and coloring agent powder on yarn and the nylon wire of blocking water thoughtlessly compile the layer, it is equipped with the rubber sleeve outside yarn and the nylon wire thoughtlessly to block water, be equipped with the recess on the terminal surface of rubber sleeve one side, be equipped with the lug on the terminal surface of rubber sleeve another side, the cooperation that the protection against rodents cover transversely passes through recess and lug is connected, be equipped with magic tape matt surface on the outside one side of rubber sleeve, be equipped with the magic tape hook surface that corresponds with magic tape matt surface on the outside other surface of rubber sleeve.

Preferably, the fluoroplastic layer is made of: any one of polytetrafluoroethylene, polyfluorinated ethylene propylene and polyvinylidene fluoride.

Preferably, the radiation cross-linked polyolefin sheath is made of the following materials: radiation crosslinked polyethylene or radiation crosslinked polypropylene.

Preferably, the deliquescent substance is: any one of calcium chloride, potassium carbonate or quicklime.

Preferably, the dye powder is: any one of carmine, lemon yellow or grass green.

Deliquescence refers to the phenomenon in which some substance absorbs or adsorbs water from the air, causing the surface to become increasingly moist and lubricious, and eventually the substance changes from a solid to a solution of the substance. When the water-blocking yarn fiber main body meets water, the water-blocking yarn fiber main body can be rapidly expanded to form jelly with a large volume, and the jelly has quite strong water-retaining capacity and can effectively prevent the growth of water trees, so that the water is prevented from continuously permeating and diffusing, and the purpose of blocking water is achieved.

Two kinds of characteristics above utilizing, when the protection against rodents cover is bitten broken, the mouse can eat inside capsaicin, leave by pungent taste stimulation, deliquescent substance in the protection against rodents cover can follow the breach department deliquescence, the yarn that blocks water can the water absorption inflation, prevent the absorptive water of deliquescent substance on the one hand, on the other hand is extruded from the breach, the jelly that the yarn that blocks water formed is through the dyeing of coloring agent, make breach department can become very striking, the staff just can in time discover, overhaul.

The protection against rodents cover is removable design, as long as tear the magic subsides and just can dismantle, it is very convenient to use, need not carry out whole section change to the cable, adopts the cooperation zonulae occludens through recess and lug between the protection against rodents cover.

The waterproof yarn has large volume after absorbing water and expanding, if too much waterproof yarn is arranged, the space in the ship is compact, the cable beside the ship can be extruded after being bitten, if too little waterproof yarn is arranged, the rat-proof sleeve is too thin and is easy to be bitten by a mouth to damage the sheath, and the design effect is lost, so the waterproof yarn and the nylon wire are mixed and woven in the rat-proof sleeve, the rat-proof sleeve has certain thickness, can not be bitten easily, and simultaneously can not expand too much after being bitten.

The fluoroplastic layer insulating layer used for the cable has excellent electric insulating property, high heat resistance, outstanding oil resistance, solvent resistance and wear resistance, good moisture resistance and low temperature resistance, and can not delay burning when encountering fire. The poly-p-benzamide fiber is a special fiber with high strength and high modulus, has good corrosion resistance and can effectively protect the lead.

The quartz glass fiber has the advantages of high-temperature insulation, ablation resistance, corrosion resistance, heat insulation, wave transmission, excellent dielectric property and good chemical stability. The cable core can be effectively protected, and the strength of the cable is improved.

The radiation crosslinking polyolefin material has excellent comprehensive performances such as mechanical property, waterproofness, environmental stress cracking resistance, chemical corrosion resistance, creep resistance, electrical property and the like, and is an excellent sheath material.

The invention has the beneficial effects that: through the improvement to cable structure, obtain one kind and have fabulous protection against rodents function, easily discover after being bitten by the mouse and destroy simultaneously, remind the staff to overhaul the cable.
