Description

Technical Field

[0001] The invention relates to the technical field of cables, and in particular to a high-toughness cable that is rat-proof. Background Art

[0002] When cables are installed, the installation environment is complex and they are often bitten by rodents. Due to their nature, rodents need to grind their teeth frequently. In order to prevent rat bites, existing cables on the market mainly use heated rodent-proof materials in rubber materials. The rodent-proof effect is achieved through odor, which will gradually weaken over time. In addition, heating the rodent-proof material will affect the toughness of the rubber layer. Based on this, a high-toughness cable that is rat-proof is proposed. Summary of the invention

[0003] The purpose of the present invention is to solve the problem that the existing cables mainly adopt heating rat-proof materials in rubber materials to prevent rat bites, and the rat-proof effect is achieved through smell, but the effect will gradually weaken over time, and heating the rat-proof material will affect the toughness of the rubber layer. A high-toughness cable that is rat-proof is proposed. By arranging a heating protective layer on the cable, when rodents (rats) damage the cable, the bubble capsule will be bitten, so that the colloidal liquid inside flows out and contacts with the heating layer composed of quicklime. The lime reacts with water to generate a large amount of heat in a short time. The heat will cause harm to rodents (rats), and will scare away rodents (rats) in the first place, thereby preventing rodents (rats) from causing fatal damage to the wires inside the cable.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A rat-proof high-toughness cable comprises a high-toughness cable body, wherein the high-toughness cable body comprises an outermost heating protection body, an isolation insulation body, a solid protection body and a metal wire core;

[0006] The heating protection body is composed of a rubber insulating surface layer, an internal fiber layer and a heating composite body;

[0007] The heating composite body comprises an inner rubber layer and an outer rubber layer, bubble capsules are evenly arranged between the inner rubber layer and the outer rubber layer, and a heating layer is filled between the inner rubber layer and the outer rubber layer.

[0008] The isolation and thermal insulation body is composed of a metal shielding layer, a gas inner protective layer, a gas buffer layer and a gas outer protective layer, and the gas buffer layer is injected with a driving gas;

[0009] The solid protective body comprises a shaping disk arranged in a polygonal shape, and an adapting opening for the metal wire core to pass through is provided in the shaping disk.

[0010] Preferably, a colloidal liquid is arranged inside the bubble capsule, and the heating layer is filled with quicklime and dispersed inside the bubble capsule.

[0011] Preferably, a plurality of axial fiber rods are arranged between the gas inner sheath and the gas outer sheath, the driven gas is filled around the axial fiber rods, and the gas inner sheath and the gas outer sheath are connected by a plurality of traction fibers.

[0012] Preferably, the shaping disk is located inside the metal shielding layer, and a rubber filling layer is arranged between the shaping disk and the metal shielding layer, and the rubber filling layer is composed of densely arranged rubber particles.

[0013] Preferably, a serrated layer is provided on the outside of the shaping disk, and the serrated layer is in close contact with the rubber particles to achieve rotational positioning of the shaping disk.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention provides a heating protection layer on the cable. When rodents (rats) damage the cable, they will bite through the bubble capsule, causing the colloidal liquid inside to flow out and come into contact with the heating layer composed of quicklime. The lime reacts with water to generate a large amount of heat in a short period of time. The heat will cause harm to the rodents (rats) and will scare away the rodents (rats) immediately, thereby preventing the rodents (rats) from causing fatal damage to the wires inside the cable.

[0016] 2. The present invention dries the colloidal liquid by heating quicklime, and the dried colloidal material will further solidify the quicklime, thereby effectively reinforcing the cables damaged by rodents (rats), enhancing the strength of the damaged parts of the cables, and ensuring that the normal use of the cable body is not affected.

[0017] 3. An isolating insulation layer is provided inside the heating protection layer, and the heat generated by the quicklime is isolated by the expelling gas in the isolating insulation layer, thereby protecting the metal wire core. Moreover, the pungent smell of the expelling gas after damage can drive away rodents (rats), thereby further achieving protection. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Example, see Figure 1-4 , a rat-proof high-toughness cable, comprising a high-toughness cable body, the high-toughness cable body comprising an outermost heating protection body, an isolation insulation body, a solid protection body and a metal wire core 17;

[0025] The heating protection body is composed of a rubber insulating surface layer 1, an internal fiber layer 2 and a heating composite; the heating composite includes an inner rubber layer 3 and an outer rubber layer 4, bubble capsules 5 are evenly arranged between the inner rubber layer 3 and the outer rubber layer 4, and a heating layer 6 is filled between the inner rubber layer 3 and the outer rubber layer 4.

[0026] It should be noted that the heating composite is arranged between the rubber insulating surface layer 1 and the built-in fiber layer 2, and will be triggered at the moment the rubber insulating surface layer 1 is damaged by rodents, thereby effectively avoiding damage to the metal wire core 17 inside.

[0027] Furthermore, a colloidal liquid is provided inside the bubble capsule 5 , and the heating layer 6 is filled with quicklime and dispersed inside the bubble capsule 5 .

[0028] It is worth noting that, except for the adhesive material, most of the materials inside the colloid liquid are water. When rodents destroy the heating complex, the bubble capsule 5 arranged inside will be damaged. The damaged colloid liquid will flow out and contact the heating layer 6 composed of quicklime. In this state, the quicklime reacts with water to generate a large amount of heat in a short time. The heat will cause harm to rodents (rats), and will scare away rodents (rats) in the first place, thereby preventing rodents (rats) from causing fatal damage to the wires inside the cable.

[0029] The colloidal liquid will dry during the heating process, and the dried colloidal material will further solidify the quicklime, thereby effectively reinforcing the cables that have been damaged by rodents (rats), enhancing the strength of the damaged parts of the cables, and ensuring that the normal use of the cable body is not affected.

[0030] The isolation insulator is composed of a metal shielding layer 7, a gas inner sheath 8, a gas buffer layer 9 and a gas outer sheath 10. The gas buffer layer 9 is injected with a repelling gas. The repelling gas is under a relatively high pressure inside. When it is not damaged, the gas can protect the cable. After being damaged, it can rush out from the damaged part as soon as possible to scare away rodents (rats).

[0031] It is worth noting that the gas buffer layer 9 is arranged in stages in the cable, and there will not be a situation where the entire cable cannot be used due to damage in one place.

[0032] It should be noted that the repelling gas is mainly composed of ammonia and other pungent odor gases, which can further scare away rodents (rats), and the gas filling effect can isolate the heat generated by the quicklime from affecting the solid protective body and the metal wire core 17;

[0033] Furthermore, a plurality of axial fiber rods 13 are arranged between the gas inner sheath 8 and the gas outer sheath 10 , the driven gas is filled around the axial fiber rods 13 , and the gas inner sheath 8 and the gas outer sheath 10 are connected by a plurality of traction fibers 14 .

[0034] It is worth noting that the tensile etching generated by the pulling fiber 14 acts between the gas inner sheath 8 and the gas outer sheath 10 to ensure the connection between the two;

[0035] Furthermore, the axial fiber rod 13 can improve the compression and cutting strength of the cable, which is a commonly used technical means. It is arranged between the gas inner sheath 8 and the gas outer sheath 10, which will absorb the smell of ammonia, reduce the chewing desire of rodents (rats), and further achieve the protection effect of the metal wire core 17 inside.

[0036] The solid protective body includes a polygonal shaping disk 11, in which an adapter port 12 is provided for the metal wire core 17 to pass through. The shaping disk 11 is multiple and stacked on top of each other to effectively fix the metal wire core 17 and ensure that the metal wire core 17 will not move inside the cable.

[0037] Furthermore, the shaping disk 11 is located inside the metal shielding layer 7, and a rubber filling layer 15 is provided between the shaping disk 11 and the metal shielding layer 7. The rubber filling layer 15 is composed of densely arranged rubber particles.

[0038] A sawtooth layer 16 is disposed outside the shaping disk 11, and the sawtooth layer 16 is in close contact with the rubber particles to achieve rotational positioning of the shaping disk 11;

[0039] It is worth noting that the serrated layer 16 is arranged at the edge of the shaping disk 11, which has two effects. First, during use, it increases the friction between the shaping disk 11 and the outer rubber filling layer 15, thereby preventing the metal wire core 17 in the shaping disk 11 from rotating and angularly offset, thereby effectively ensuring the positioning of the metal wire core 17 under different stress states; secondly, the serrated layer 16 arranged in a serrated shape will affect the normal chewing of rodents (rats) when they chew, causing them to be injured, thereby achieving the effect of protecting the metal wire core 17 in the shaping disk 11.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
