Description

Technical Field

[0001] The invention relates to the technical field of cables, in particular to a rat-proof, ant-proof and ultraviolet-resistant power cable. Background Art

[0002] Wires are used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables. In modern society, wires and cables can be seen everywhere, such as wires and broadband access lines used in homes and hotels; power cables and overhead cables laid by power departments. Wires and cables occupy a very important position in the national economy and social activities. With the rapid development of the economy, the wire and cable industry has become the second largest industry in my country. Cables can be laid underground, in pipelines, or in cable trenches. In the construction of some bridges, tunnels or large projects, power cables are generally laid in open-air locations. No matter what laying method is used, cables are inevitably damaged by termites, insects or rodents. Once the cable is damaged by gnawing, it will cause water ingress and short circuit. In severe cases, it will cause the cable to explode, causing fire or power outages.

[0003] Termites and rats are the main hazards to plastic cables and optical cables, causing many accidents every year and huge economic losses. In the prior art, toxic anti-termite agents are added to the plastic materials of the cable outer sheath, mainly for "poisoning". However, when adding the agent, most of them are filled in the interlayer of the cable in the form of liquid or powder. When termites or rats damage the surface of the cable, these powders or liquids will flow out, and termites or rats will die after using these agents, thereby playing the role of anti-rat and ant. However, after the protective layer outside these powders or liquids is damaged, it is easy to flow out from this position, resulting in the loss of the protective effect of this position after the powder or liquid flows out. In addition, the powder or liquid that flows out will pollute the surrounding environment. Summary of the invention

[0004] The purpose of the present invention is to provide a rat-proof, ant-proof and UV-resistant power cable, so as to solve the problem that the rat-ant-proofing method used in the prior art is easy to cause pollution to the surrounding environment.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: A rat-proof, ant-proof and UV-resistant power cable comprises a conductor, an insulating layer, a shielding layer, an inner protective layer, an armor layer, a drug layer and an outer protective layer which are closely arranged in sequence from the inside to the outside. The drug layer comprises a plurality of drug strips which surround the armor layer and are arranged along the length direction of the armor layer. A tube cavity is arranged in the drug strip along the length direction thereof, and the tube cavity is filled with a colloid mixture formed by mixing gel and a rat-killing and ant-killing drug.

[0006] A further technical solution is that the rodent-ant killer includes a combination of one or more of cypermethrin, imidacloprid, and fipronil, and a combination of one or more of fipronil, dalon, and coumatetralyl; and the gel is a combination of one or more of carrageenan, xanthan gum, gelatin, and guar gum.

[0008] A further technical solution is that the rat-proof and ant-proof material includes a combination of one or more of capsaicin, menthol, cyromazine, and triptolide; the anti-ultraviolet material is a UV absorber or a hindered amine light stabilizer; the UV absorber is a combination of one or more of benzophenones and benzotriazoles; the hindered amine light stabilizer is specifically a combination of one or more of piperidine derivatives and imidazolinones.

[0009] A further technical solution is that the inner protective layer is made of polyethylene or polyvinyl chloride, the armor layer is steel strip armor or steel wire armor, the insulation layer is made of cross-linked polyethylene or polyvinyl chloride, and the shielding layer is copper strip shielding or copper wire braided shielding.

[0010] A further technical solution is that a plurality of medicine strips are densely arranged in a spiral shape around the surface of the armor layer, and the plurality of medicine strips are overlapped and arranged in at least two layers between the armor layer and the protective layer, and the spiral directions of the medicine strips in two adjacent layers are opposite.

[0011] A further technical solution is that a filler is arranged between the plurality of drug strips, and the filler includes polyethylene resin and capsaicin mixed in the polyethylene resin.

[0013] A further technical solution is that the preparation steps of the slow-release rat and ant repellent are as follows: Step S1, weighing a certain amount of triptolide powder, dispersing it in deionized water, and ultrasonically treating it to make it uniformly dispersed to obtain a triptolide solution; Step S2, in another container, dissolving the monomer N-isopropylacrylamide in deionized water, and stirring evenly to obtain a monomer solution; Step S3, slowly adding the triptolide solution into the monomer solution, and continuing stirring to obtain a mixed solution; Step S4, adding ammonium persulfate to the mixed solution, reacting at 60° C. for several hours under nitrogen protection, initiating monomer polymerization to form a nanogel network, wherein triptolide is encapsulated inside the nanogel network, and a sustained-release rat and ant repellent is obtained.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting an outer protective layer, it can play a preliminary protective role and ensure the internal safety and stability; 2. By setting a medicine strip in the medicine layer and a gel mixture filled in the medicine strip, compared with traditional powders or liquid medicines, the gel mixture will not leak out even if it is destroyed, and can still maintain a fixed shape, and can stably play a role before the medicine strip is completely bitten through or broken and missing; and with the help of the gel, the rat and ant killing agent mixed inside it can be protected, the service life of the rat and ant killing agent is increased, and it is ensured that it can exert its efficacy; 3.

[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] Figure 1 to Figure 2 An embodiment of the present invention is shown.

[0020] Embodiment 1: A rat-ant-proof and ultraviolet-resistant power cable comprises a conductor 1, an insulating layer 2, a shielding layer 3, an inner protective layer 4, an armor layer 5, a drug layer 6 and an outer protective layer 7 which are arranged closely from the inside to the outside. The drug layer 6 comprises a plurality of drug strips 8, which surround the armor layer 5 and are arranged along the length direction of the armor layer 5. A lumen 9 is arranged in the drug strip 8 along its length direction, and the lumen 9 is filled with a gelatinous mixture formed by mixing gel and a rat-ant-killing drug. By arranging the outer protective layer 7, a preliminary protective effect can be played to ensure the safety and stability of the interior. By arranging the drug strip 8 and the gelatinous mixture filled in the drug strip 8 in the drug layer 6, compared with traditional powder or liquid medicine, the gelatinous mixture will not leak out even if it is destroyed, and can still maintain a fixed shape, and can stably play a role before the drug strip 8 is completely bitten through or broken and missing; and the rat-ant-killing drug mixed therein can be protected by means of gel, and the service life of the rat-ant-killing drug is increased to ensure that it can play its efficacy. By providing the armor layer 5, the protection effect of the cable can be further improved.

[0021] The rat and ant killer includes a combination of one or more of bifenthrin, imidacloprid, and fipronil, and a combination of one or more of fipronil, dalon, and coumatetralyl; the gel is a combination of one or more of carrageenan, xanthan gum, gelatin, and guar gum.

[0022] The outer protective layer 7 includes polyethylene resin, polypropylene resin, EPDM rubber, styrene-butadiene rubber, rat-proof and ant-proof materials and UV-resistant materials. By adding UV-resistant materials to the outer protective layer 7, it is possible to prevent the cable from being exposed to the outside and aging rapidly under UV irradiation, thereby reducing the service life of the cable. The UV-resistant materials can effectively increase the service life of the outer protective layer 7, thereby improving the internal stability.

[0023] The rat and ant-proof material includes a combination of one or more of capsaicin, menthol, cyromazine, and triptolide; the anti-ultraviolet material is an ultraviolet absorber or a hindered amine light stabilizer; the ultraviolet absorber is a combination of one or more of benzophenones and benzotriazoles; the hindered amine light stabilizer is specifically a combination of one or more of piperidine derivatives and imidazolinones.

[0024] The inner protective layer 4 is made of polyethylene or polyvinyl chloride, the armor layer 5 is steel tape armor or steel wire armor, the insulating layer 2 is made of cross-linked polyethylene or polyvinyl chloride, and the shielding layer 3 is copper tape shielding or copper wire braided shielding.

[0025] A plurality of agent strips 8 are densely arranged in a spiral shape around the surface of the armor layer 5, and the plurality of agent strips 8 are overlapped and arranged in at least two layers between the armor layer 5 and the protective layer, and the spiral directions of the agent strips 8 of two adjacent layers are opposite. Through the multiple layers of agent strips 8, effective protection can be formed, and due to the cross-spiral arrangement, all gaps can be effectively sealed to prevent termites from invading the interior of the cable through the gaps.

[0026] A filler is arranged between the plurality of medicine strips 8, and the filler includes polyethylene resin and capsaicin mixed in the polyethylene resin. By arranging the filler with capsaicin, termites and mice can be driven away by the smell of capsaicin, so that termites and mice will not have the desire to gnaw the medicine strips 8 or the filler.

[0027] The outer wall of the outer protective layer 7 is provided with an anti-rat and ant block 10 at intervals, and a storage cavity is provided inside the anti-rat and ant block, and the storage cavity is filled with a slow-release agent to repel rats and ants. The upper side of the anti-rat and ant block 10 is provided with an addition port 11 and a sealing plug for closing the addition port 11, and the lower side of the anti-rat and ant block 10 is provided with a plurality of slow-release holes 12. By providing the anti-rat and ant block 10, it can be arranged on the cable at intervals, so as to drive away the surrounding termites, mice, etc. with the help of the slow-release agent to repel rats and ants in the anti-rat and ant block 10, and prevent the termites, mice, etc. from approaching the cable and causing damage to the cable. The present invention adopts a variety of defense and repelling measures. Even if a certain layer of defense measures loses its effect, there will be other defense measures to protect the cable. For example, the anti-rat and ant block 10 is used as the first layer of defense measures to repel termites or mice by emitting a smell that termites or mice do not like to the surrounding air. When the anti-rat and ant block 10 fails to work, the anti-rat and ant material contained in the outer protective layer 7 is used to repel termites or mice. When the outer protective layer 7 fails to work, the agent layer 6 is used to kill termites or mice. And after these are destroyed, the armor layer 5 can be used for protection. Multi-layer protection can effectively prevent termites or mice from the cable, and the cable can work stably for a long time.

[0028] The preparation steps of the slow-release rat and ant repellent are as follows: Step S1, weighing a certain amount of triptolide powder, dispersing it in deionized water, and ultrasonically treating it to make it uniformly dispersed to obtain a triptolide solution; Step S2, in another container, dissolving the monomer N-isopropylacrylamide in deionized water, and stirring evenly to obtain a monomer solution; Step S3, slowly adding the triptolide solution into the monomer solution, and continuing stirring to obtain a mixed solution; Step S4, adding ammonium persulfate to the mixed solution, reacting at 60° C. for several hours under nitrogen protection, initiating monomer polymerization to form a nanogel network, wherein triptolide is encapsulated inside the nanogel network, and a sustained-release rat and ant repellent is obtained.
