The present invention can be used in multiple industrial fields such as optical computing, fiber optic sensing, and smart grid. Background Art

[0002] As a carrier for high-speed wired communication, the usage amount of optical cables is increasing day by day. The core of an optical cable is the optical fiber for transmitting light. In an optical cable, the components other than the optical fiber are all for protecting the optical fiber. However, after the optical cable is laid indoors and outdoors, it is often gnawed, bitten, and chewed by various toothed animals, and in severe cases, it causes communication interruption, bringing immeasurable economic losses. For this reason, people in the technical field have conducted a large amount of research to prevent damage by rats and ants.

[0003] CN107065088A discloses an anti-rat optical cable, a preparation method thereof, and an outer sheath material for the anti-biological optical cable. The anti-biological optical cable includes a cable core, and the cable core is formed by twisting a central strengthening member and a plurality of tubes around the strengthening member, and a plurality of optical fibers are provided in the tubes; a steel strip is wrapped around the cable core, and an outer sheath is extruded on the outermost layer of the cable core; the stainless steel strip is a crimped stainless steel strip with a crimping width of 5 mm and a height of 2.5 mm, and hot melt adhesive is first injected at the lap joint of the crimped steel strip, and then a plurality of stainless steel wires with a diameter of 0.4 mm are wrapped around the crimped stainless steel strip; its outer sheath has effects such as wear resistance, ultra-low smoke, halogen-free, and rat repellent; the outer sheath material includes the following components in parts by mass: 25-35 parts of modified high molecular weight polyethylene, 3-6 parts of polyphenylene sulfone resin, 9-13 parts of thermoplastic polyurethane elastomer, 1-2 parts of a mixture of pentaerythritol ester and phosphite ester, 2-4 parts of carbon black masterbatch, 0.5-1 part of a rheological modifier, 1-3 parts of stearic acid, 0.5-1.5 parts of zinc stearate, 3-5 parts of diatomaceous earth, 1-3 parts of β-type hemihydrate gypsum, 2-4 parts of silicon dioxide, 1-3 parts of asbestos fiber, 5-6 parts of rhododendron molle pollen; the rheological modifier is specifically at least one monomer with a carboxyl functional group of 8%-60%, acrylamide of 40%-92%, and phosphorus atoms of 0%-5%, and the total of the monomer, acrylamide, and phosphorus atoms is 100%. However, it has defects such as overly complex chemical components, very slow processing speed of the crimped stainless steel strip with a width of 5 mm and a height of 2.5 mm, not very ideal actual anti-rat and ant performance, and complex manufacturing.

[0004] CN101661142A discloses an anti-rat-bite strengthening yarn for an optical cable and a preparation method thereof. The anti-rat-bite strengthening yarn for an optical cable is composed of 76.8-83.2 wt% of ECR glass fiber yarn, 16-22 wt% of EVA hot melt adhesive, and 0.8-1.2 wt% of capsaicin. The production of its capsaicin causes a large amount of environmental pollution, and the anti-rat performance is not ideal enough.

[0005] CN221883959U discloses an optical cable that prevents rats from gnawing, which includes a protective sleeve. Long grooves are circumferentially formed on the surface of the protective sleeve, and protective grooves located above the long grooves are circumferentially formed on the surface of the protective sleeve. An anti-rat layer is fixedly installed inside the protective sleeve. Hollow capsules are circumferentially and fixedly installed inside the anti-rat layer. A reinforcing layer is fixedly installed inside the hollow capsules. A waterproof layer is fixedly installed inside the reinforcing layer. For this optical cable that prevents rats from gnawing, during the manufacturing process of the optical cable, a certain amount of drugs for expelling or poisoning rats can be added inside the hollow capsules. When underground rats gnaw on the optical cable, the drugs stored inside the hollow capsules will enter the rats' bodies, thereby expelling or poisoning the rats. Then, waterproofing is carried out through the waterproof layer, and an insulating layer is used for insulation, thus achieving multiple protections for the optical cable. However, the drugs for expelling rats inside the hollow capsules cannot achieve the desired effect. After the drugs for poisoning rats are eaten by the rats, the poisoned rats cause further environmental pollution.

[0006] Therefore, the methods of mechanical and physical anti-rat and chemical anti-rat in the existing optical cable industry need to be further improved. Summary of the Invention

[0034] Embodiment 3: Please refer to Figure 6 and refer to Figures 1 to 5 A bio - resistant optical cable with a frame structure is basically the same as Embodiment 1 and Embodiment 2, except that: an annular cavity 614 is provided inside the outer protection layer 61. The annular cavity 614 is located inside the outer sleeve 611 and the outer connecting strip 612. The annular cavity 614 is fully or partially penetrated. Penetration means connecting adjacent outer holes 6110, and there are also cavities between the outer holes 6110.

[0035] In this embodiment, the annular cavity 614 is filled with a rat - sticky material.

[0036] The above - mentioned rat - sticky material is rat - sticky glue, which is the rat - sticky glue used in the prior art, such as the rat - sticky glue coated on the rat - sticky board sold in the Pinduoduo or Taobao APP, for example, the rat - sticky glue of the brand: MIEBOSHI (Dr. MIE). Again, for example, the glue used in the product named: Weishenhu Powerful Upgraded Rat - Sticky Board, or the whole rat - sticky board, or the rat - sticky board is crushed and filled in. The above - named rat - sticky boards can be purchased on Pinduoduo and Taobao APP; other similar ones, as long as they can achieve the corresponding functions and effects, are acceptable.

[0037] In any of the above - mentioned embodiments of a bio - resistant optical cable with a frame structure, the outer cavity 610 is filled with a rat - proof material; the filling degree of the rat - proof material in the outer cavity 610 is not less than 98%.

[0038] The above - mentioned bio - resistant optical cable with a frame structure has a rat - proof material that is iron filings, glass powder, fiberglass, or glass fiber yarn with a length less than 0.3 mm, or a mixture of at least two of the above.

[0039] In any of the above - mentioned embodiments of a bio - resistant optical cable with a frame structure, the first protective layer 4 is a rat - proof layer.

[0040] Furthermore, in any of the above - mentioned embodiments of a bio - resistant optical cable with a frame structure, the material of the first protective layer 4 is glass fiber - reinforced plastic, where the glass fiber content is not less than 80%, the glass fiber distribution uniformity is not less than 95%, and the length of the glass fiber is not greater than 0.3 mm.

[0041] In any of the above - mentioned embodiments of a bio - resistant optical cable with a frame structure, the material of the second protective layer 5 is plastic.

[0042] In any of the above-described embodiments, a bio-resistant optical cable having a frame structure, the material of the central strength member 1 is steel wire, iron wire, aluminum wire or glass fiber reinforced plastic rod.

[0043] In any of the above-described embodiments, a bio-resistant optical cable having a frame structure, the material of the loose tube 2 is modified polypropylene or polybutylene terephthalate.

[0044] In any of the above-described embodiments, a bio-resistant optical cable having a frame structure, the optical fiber 3 is of single-mode type or multi-mode type.

[0045] In any of the above-described embodiments, a bio-resistant optical cable having a frame structure, the material of the peripheral strength member 7 is steel wire, iron wire, aluminum wire or glass fiber reinforced plastic rod.

[0046] In any of the above-described embodiments, a bio-resistant optical cable having a frame structure, the material of the third protective layer 8 is glass fiber reinforced plastic tape or steel tape.

[0047] In any of the above-described embodiments, a bio-resistant optical cable having a frame structure, the material of the outer sheath 9 is plastic.

[0048] A method for manufacturing the above-described bio-resistant optical cable having a frame structure, comprising the following steps: First step: The step of manufacturing the cable core component: First, manufacture the cable core, wrap the first protective layer outside the cable core, and make the butt joint of the first protective layer firmly bonded. Wrap the melted plastic outside the second protective layer. The thickness of the first protective layer is not less than 3 mm; Second step: The step of manufacturing the protective component: Take the inner protective layer, the outer protective layer, and the peripheral strength member; embed the peripheral strength member into the inner hole of the inner protective layer and the outer hole of the outer protective layer; fill the annular cavity of the outer protective layer with a rat glue material; by rotation, make each outer convex strip completely snap into the corresponding clamping groove, and make the outer convex strip and the corresponding clamping groove tightly combined to form a connecting component, so that the inner protective layer, the connecting component, and the outer protective layer are combined to form an integrated frame structure; fill the outer cavity with a rat-proof material, and make the filling degree of the rat-proof material in the outer cavity not less than 98%; the overall thickness of the protective component is greater than 5 mm; Third step: The step of manufacturing the semi-finished product: Take the cable core component manufactured in the first step and pass it through the inner cavity of the protective component to form a semi-finished product; Fourth step: Steps for manufacturing the finished product: Take the semi-finished product and pass it through the pre-forming die of the third protective layer to form a coated semi-finished product. Further draw the coated semi-finished product and pass it through the die core of the sheath extrusion head. Melted plastic is extruded between the die core and the die sleeve of the sheath extrusion head and coated on the coated semi-finished product, and then drawn through the cooling water tank to form a finished anti-biological optical cable with a frame structure, thus completing the manufacturing of the anti-biological optical cable with a frame structure.

[0049] As a further improvement, in this application, at least one middle protective layer can be added between the outer protective layer 61 and the inner protective layer 62 of the protective component 6, and the adjacent layers of the outer protective layer 61, the middle protective layer, and the inner protective layer 62 are connected by the connecting component 63. After manufacturing, the protective component 6 is an integral structure.

[0050] In this application, the cable core component is not limited to that in Embodiment 1. It can be in other forms as long as it contains at least one optical fiber inside. For example, the cable core can be a sleeve, and the inside of the sleeve has an optical fiber or an optical fiber ribbon; in the cable core, there can also be at least one optical fiber ribbon in the loose tube 2, and the optical fiber ribbon has optical fibers inside; in the cable core, there can also be at least one loose tube 2, and other loose tubes are replaced by filling ropes; even, it can be a tight jacket or a single soft optical cable; there can also be several protective layers between the second protective layer 5 and the cable core.

[0051] Similarly, in this application, there can also be more protective layers between the protective component 6 and the outer protective layer 9.

[0052] In this application, the thickness of the first protective layer 4 is at least 3 mm; the first protective layer with such a thickness and the material of the first protective layer make it easy to penetrate into the meat and tooth gaps of animals, causing severe pain, making it difficult for mice and ants to persist in gnawing to the cable core. Therefore, it has better protective performance for the cable core and optical fibers.

[0053] In this application, through the overall structure of the outer protective layer 61, the connecting component 63, and the inner protective layer 62 of the protective component 6, the protective component 6 has a relatively thick thickness and actually forms a hard frame structure. Mice and ants need to gnaw through the outer sleeve 611 or the outer connecting strip 612, as well as the inner sleeve 621 or the inner connecting strip 622, and the anti-rat material filled in the outer cavity 610; then they can reach the cable core component. Therefore, excellent anti-rat performance is achieved through a hard and thick enough frame structure and the like.

[0054] In this application, the anti-rat function is creatively achieved by filling the annular cavity 614 with rat-catching material. After testing, even when the rat-catching material is laid flat indoors and outdoors, due to its excellent bonding performance, rats will be stuck after climbing on it or biting it with their mouths. Even rats as long as 40 cm can be easily stuck. For even larger rats, after biting, due to the bonding, a memory effect is formed on them. After being used and tested in mountainous areas with a large number of rats, for the cable, cameras are externally installed along the line direction for monitoring. There is no phenomenon that the protective component 6 is bitten or punctured for 269 consecutive days. For ants, once they bite, they will be stuck and unable to move. Therefore, the design requirements are fully met.

[0055] In the present application, for the peripheral strengthening member, compared with the central tube-type optical cables in the prior art, such as the structures in GYXTY and GYXTS, no stranding is required. Therefore, the production speed is faster, and the investment in equipment, labor, and site is saved.

[0056] As a further improvement, in the present application, the inner anti-layer and the outer anti-layer can also have a spiral structure in the same direction. In this way, the anti-biting performance can be made better.

[0057] In the present application, the hard material of the third protective layer serves as the first anti-rat and anti-ant layer, which can be a closed pipe structure, such as the steel belt lap joint being welded; the protective component is a frame body, serving as the second anti-rat and anti-ant layer. On the one hand, it prevents rats and ants through its hardness. On the other hand, through its sufficient thickness, it can prevent the limited biting ability of rats and ants, so that they cannot bite it completely and then actively give up. In addition, it also has the protection of anti-rat materials and creatively uses rat-catching materials to bond and prevent rats and ants; in addition, the first protective layer also has excellent anti-rat and anti-ant performance; through the above combination, a very ideal anti-rat and anti-ant effect is achieved.

[0058] As a further simplified improvement, a bio-resistant optical cable with a frame structure in the present application has a cable core component, the cable core component is coated with rat-catching material, and the rat-catching material is coated with an outer protective layer.

[0059] Furthermore, there is a tape layer between the rat-catching material and the outer protective layer to prevent the rat-catching material from overflowing. The tape layer is a water-blocking tape or non-woven fabric or polyester tape, which is helically coated outside the rat-catching material. There is an overlap between the front and back spirals of the tape layer, and the back spiral covers at least 3 mm of the front spiral; moreover, the rat-catching material is the rat-catching cardboard in the prior art, and the rat-catching cardboard is composed of a first bonding paper, rat-catching glue, and a second bonding paper. The rat-catching cardboard is longitudinally or helically coated on the cable core component. An ideal anti-rat and anti-ant effect is achieved through the strong bonding property of the rat-catching material.

[0060] As a further improvement, the present application is not limited to being used for optical cables and can also be used for electric cables, that is, the cable core component has conductive components, and even has both optical fibers and conductive components.

[0061] In the present application, the annular cavity, as a deformation and improvement, may be only inside the outer connecting strip 612, that is, each outer connecting strip 612 has an annular cavity filled with mouse glue.

[0062] Certainly, as a further improvement, the inner connecting strip 622 may also have an annular cavity, and the annular cavity is also filled with mouse glue.

[0063] In the present application, the percentage content of the solid substance is based on weight percentage.

[0064] The present application has the following main beneficial technical effects: simple structure, easy to manufacture, good environmental protection performance, and excellent mouse-proof performance.

[0065] The present application can be used as an intelligent sensor and an intelligent sensing element; since it can transmit voice and images, it can also be used as a physical sensor, such as a voice sensor and an image sensor; since it transmits optical signals through the total reflection principle, it can also be used as a distance sensor; the optical fiber in the present application is itself an optical waveguide, so it can be used as an optical waveguide, such as an array optical waveguide and a diffraction optical waveguide; the present application can also be used in the field of optical computing, as part of optical computing, optical computing, and optical network computing, and as part of optical chip computing.

[0066] The above embodiments are only the preferred technical solutions of the present invention and should not be regarded as limitations on the present invention. The protection scope of the present invention should be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, the equivalent replacement improvements within this scope are also within the protection scope of the present invention.
