Description

Technical Field

[0001] The present invention belongs to the technical field of optical cables, and particularly relates to a desert anti-radiation and anti-wear optical cable. Background Art

[0002] With the rapid development of modern communication technologies, fiber optic communication, as a high-speed, high-capacity, and low-loss communication method, has been widely applied in various fields. However, in some special environments, such as desert areas, traditional optical cables face many severe challenges, which seriously limit the reliable deployment and application of fiber optic communication networks in desert regions.

[0003] In the prior art, solar radiation in desert areas is intense, and the intensity of ultraviolet radiation is particularly prominent. When exposed to high-intensity ultraviolet radiation for a long time, the fiber structure of ordinary optical cables will be damaged. Ultraviolet rays can penetrate the outer sheath of the optical cable and act on the fiber core and cladding materials, causing changes in the molecular structure of the materials, thereby changing the refractive index distribution of the fiber and reducing the communication performance of the optical cable. In the case of frequent sand activities, sand grains and gravel will continuously impact and rub the outer sheath of the optical cable with the flow of air. Under the action of such long-term mechanical wear, ordinary optical cable outer sheath materials are prone to breakage, scratching, etc., reducing the integrity and reliability of the optical cable. For this reason, we propose a desert anti-radiation and anti-wear optical cable to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a desert anti-radiation and anti-wear optical cable that can overcome or at least partially solve the above problems.

[0005] To solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a desert anti-radiation and anti-wear optical cable, including an optical fiber, and further including: an outer protective layer, on the outer surface of which a dynamic deformation area is provided; wherein, the dynamic deformation area includes an adaptive rough layer formed by a piezoelectric ceramic array and a matrix, and the matrix has a hollow microcapsule structure; when the piezoelectric ceramic array is impacted by sand grains to generate a pulsed current, it is converted into energy to the dynamic deformation area to adjust the roughness of the outer protective layer; a transition layer, provided on the inner wall at the bottom of the outer protective layer, for thermal radiation shielding and mechanical shock buffering; a gas transmission channel arranged in a spiral shape, provided inside the transition layer, and a medium is filled in the gas transmission channel; a repair layer, provided between the transition layer and the optical fiber, for self-repair protection of the core sheath of the optical fiber.

[0006] Preferably, the matrix includes a first protective layer, a second protective layer, and a conductive graphene grid, and a repair unit is provided in the second protective layer to prevent surface wear and damage.

[0007] Preferably, the first protective layer and the second protective layer are made of shape memory polyurethane material, and silicon carbide nanowires are arranged inside. The silicon carbide nanowires are inserted into the first protective layer at an angle of °.

[0008] Preferably, capsule bodies are arranged in an array inside the second protective layer. Liquid silane is arranged inside the capsule bodies, and the rupture threshold of the capsule bodies is MPa.

[0009] Preferably, the piezoelectric ceramic array is embedded in the surface of the matrix in a right-handed helical shape. The bottom of the piezoelectric ceramic array is connected with an energy conversion module through a conductive adhesive. The energy conversion module includes a thermoelectric generator and a micro power storage unit. The energy conversion module is arranged inside the second protective layer.

[0010] Preferably, the transition layer includes a sealing layer fixed on the bottom surface of the outer protective layer. The bottom of the sealing layer is fixedly connected with an isolation layer. The bottom of the isolation layer is fixedly connected with a compressive layer. The bottom of the compressive layer is fixedly connected with an interface layer.

[0011] Preferably, the sealing layer is made of a fluororubber-aramid woven composite film material. The isolation layer is made of a silica aerogel material. A heat conducting member is embedded in the isolation layer to form a three-dimensional heat conduction barrier. The heat conducting member is a silicon carbide nanowire.

[0012] Preferably, the isolation layer is prepared by sol-gel method with silica nanochains interwoven into a three-dimensional network with a porosity of 99.2%. The compressive layer includes a high-density graphene foam layer and a low-density graphene foam layer. The interface layer is a boron nitride h-BN nanosheet coating.

[0013] Preferably, the gas transmission channel is arranged inside the compressive layer. The inner wall of the gas transmission channel is provided with a heat insulation layer. The heat insulation layer is a silica aerogel coating. The medium inside the gas transmission channel is argon. Rubber sealing caps are arranged at both ends of the gas transmission channel.

[0014] Preferably, the repair layer includes a UV-cured acrylic resin layer fixed on the bottom surface of the transition layer. Repair capsules and platinum catalyst nanoparticles are arranged inside the UV-cured acrylic resin layer. A polyhexamethylene guanidine antibacterial coating is fixed on the top of the UV-cured acrylic resin layer.

[0015] After adopting the above technical solutions, the present invention has the following beneficial effects compared with the prior art:

[0016] Through the adaptive rough layer formed by the composite of the piezoelectric ceramic array and the matrix, when the pulsed current is generated by the impact of sand grains, the energy can be converted to this area to adjust the roughness of the outer protective layer. This enables the optical cable to adaptively change the surface state when suffering from wind and sand impact in the desert environment, reducing the abrasion of the sand grains on the outer protective layer, improving the abrasion resistance of the optical cable. At the same time, the transition layer can form a good protective area outside the optical fiber, having good heat insulation and radiation resistance effects, preventing the influence of high temperature on the optical fiber communication performance; meanwhile, it plays a role in mechanical shock buffering. When being impacted by external forces, it can absorb and disperse the impact force, protecting the internal optical fiber structure of the optical cable from damage.

DETAILED DESCRIPTION OF THE INVENTION

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, so that those skilled in the art can implement it with reference to the text of the specification.

[0026] It should be understood that the terms such as "having", "comprising" and "including" used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0027] In the description of the present invention, the orientation or positional relationship indicated by the terms "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0028] Embodiment 1: Refer to Figures 1 - 6 , a desert anti-radiation and anti-wear optical cable, optical fiber 6, further comprising: an outer protective layer 1, the outer surface of the outer protective layer 1 is provided with a dynamic deformation area; wherein, the dynamic deformation area includes an adaptive rough layer formed by a piezoelectric ceramic array 14 and a matrix, and the matrix has a hollow microcapsule structure; when the piezoelectric ceramic array 14 is impacted by sand grains to generate a pulsed current, it is used to adjust the roughness of the outer protective layer 1 through energy conversion to the dynamic deformation area; a transition layer 2, arranged on the inner wall of the bottom of the outer protective layer 1, for heat radiation shielding and mechanical shock buffering; a gas transmission channel 3 arranged in a spiral shape, arranged inside the isolation layer 22, and the gas transmission channel 3 is filled with a medium; a repair layer 5, arranged between the isolation layer 22 and the optical fiber 6, for self-repair protection of the core sheath of the optical fiber 6.

[0029] In this embodiment, the optical cable is composed of an outer protective layer 1, a transition layer 2, a gas transmission channel 3, and a repair layer 5. Its core innovation lies in realizing long-term protection in the extreme desert environment through the synergistic mechanism of dynamic deformation - energy closed-loop - self-repair. Among them, the surface layer of the outer protective layer 1 is a dynamic deformation area, and its core is composed of a composite of a piezoelectric ceramic array 14 and a matrix with hollow microcapsules. When the piezoelectric ceramic array 14 is impacted by sand grains, it generates a pulsed current, triggering a change in the molecular chain structure of the matrix, dynamically adjusting the surface roughness. The smooth state can reduce sand grain adhesion, and the rough state reduces the subsequent impact energy. The microcapsules in the matrix rupture when cracks form, releasing a repair agent to fill the damage, forming a continuous protective surface, blocking the intrusion path of sand and dust. Compared with the external silica gel layer in the traditional optical cable structure, in the high-roughness state, the contact area between sand grains and the surface decreases, the friction coefficient decreases, and the further wear rate decreases, thus achieving a good anti-wear effect and well coping with the application of the optical cable in the desert area environment. Moreover, the outer protective layer 1 has the characteristic of self-repair. For example, when the optical cable is damaged by friction with the sandy ground during erection and dragging, it can be self-repaired through the structure on the outer protective layer 1, effectively reducing the manual maintenance cost and improving the maintenance work efficiency. Moreover, driving the roughness adjustment and repair process does not require external energy supply, is convenient to operate, and saves manufacturing costs;

[0030] The isolation layer 22 is located on the inner wall of the outer protective layer 1 and realizes thermal radiation shielding and mechanical buffering through a multi-layer composite structure. A spiral gas transmission channel 3 is embedded inside it. The flow of the medium in the channel can carry away the surface friction heat. The composite structure material reflects most of the infrared radiation, blocking the inward transfer of external high temperature, and absorbs the impact vibration energy through a flexible structure. The gas transmission channel 3 is embedded in the isolation layer 22 in a spiral structure, and the flow of the medium forms an air flow barrier around the surface of the optical cable. At the same time, the spiral path enhances heat convection, preventing local overheating of the outside of the optical cable in the high-temperature desert environment and making the outside surface of the optical cable receive heat more evenly;

[0031] The repair layer 5 is located between the isolation layer 22 and the optical fiber 6 and contains a protective layer and a repair agent. The protective layer can well wrap the optical fiber 6 and protect the outer core sheath of the optical fiber 6, enhancing the anti-bending and anti-impact strength; the repair agent releases repair materials when the core sheath of the optical fiber 6 is damaged, and is cured by light or heat to restore the structural integrity. The repair process does not interfere with the signal transmission, ensuring the stable transmission of optical signals, avoiding the cumbersome maintenance operation method of finding and repairing through specific instruments and manual work in the prior art, and reducing the occurrence of fault phenomena during the use of the optical cable.

[0032] Example 2: Refer to Figure 4, which is basically the same as Embodiment 1. Furthermore: The substrate includes a first protective layer 101, a second protective layer 102, and a conductive graphene grid 13. A repair unit is provided in the second protective layer 102 to prevent surface wear and damage. The first protective layer 101 and the second protective layer 102 are made of shape memory polyurethane material. Silicon carbide nanowires are provided inside 101, and the silicon carbide nanowires are inserted into the first protective layer 101 at an inclination angle of 30°. An array of capsule bodies 1021 is provided inside the second protective layer 102. Liquid silane 1022 is provided inside the capsule bodies 1021. The rupture threshold of the capsule bodies 1021 is 5 MPa.

[0033] Among them, the first protective layer 101 uses a shape memory polyurethane matrix, and silicon carbide nanowires are inserted into it at an inclination angle of 30°. The traditional homogeneous protective layer relies on the material thickness to resist impact. In the present invention, when sand grains impact the surface at high speed, the inclined arrangement of the silicon carbide nanowires decomposes the impact force into axial and tangential components through the stress deflection mechanism. The tangential component is absorbed by the elastic deformation of the polyurethane matrix, and the axial component is conducted along the nanowires to the deep structure, avoiding local cracking caused by stress concentration. The thermal response characteristics of the shape memory polyurethane enable the material to undergo controllable soft-hard state switching under the desert day-night temperature difference. It softens during the day to absorb the impact kinetic energy and hardens at low temperature at night to maintain the structural rigidity. In addition, the staggered network structure formed by the nanowires at an inclination angle of 30° significantly improves the shear strength and prevents interlayer delamination caused by sand grain embedding. The capsule bodies 1021 of the second protective layer 102 are embedded in the shape memory polyurethane in a honeycomb array. The rupture threshold of a single capsule body 1021 is set at 5 MPa, which is equivalent to the stress generated by a 1-mm-diameter sand grain impacting at 25 m / s. When the impact force that the first protective layer 101 fails to completely dissipate is transmitted to the second protective layer 102, the capsule bodies 1021 in the impacted area rupture, releasing the liquid silane 1022. The liquid silane 1022 infiltrates into the cracks through capillary action and reacts with trace moisture in the environment or a preset photoinitiator to form a three-dimensional cross-linked silicone network, realizing in-situ curing repair. The shape memory polyurethane matrix provides a contraction stress during the repair process to assist in crack closure, ensuring seamless bonding at the repair interface;

[0034] The piezoelectric ceramic array 14 is embedded in the surface of the matrix in a right-handed spiral shape. When sand grains impact the surface at high speed, the spiral arrangement causes stress waves to propagate along a spiral path, triggering adjacent piezoelectric ceramic sheets to deform in sequence, forming a continuous pulsed current. A single impact can generate a voltage of 0.1 - 0.5V. The right-handed design gives a tangential component to the impact force, and through the centrifugal effect, the sand grains are thrown away from the surface along the spiral tangent direction, reducing the probability of secondary impact, effectively reducing the wear caused by repeated impacts, and at the same time preventing heat dissipation problems caused by dust accumulation. The energy conversion module 15 is integrated inside the second protective layer 102. The piezoelectric ceramic array 14 is electrically connected to the thermoelectric generator. A part of the electrical energy is used to assist in adjusting the surface roughness of the matrix through the Joule heat generated by the self-heat dissipation of the piezoelectric ceramic array 14, and another part of the electrical energy is transmitted to the micro energy storage unit through the thermoelectric generator. The energy storage unit uses a solid-state lithium-sulfur battery and is embedded in the second protective layer 102 for storing electrical energy. In a preferred embodiment, an energy conversion module 15 is provided every 10 meters in each cable, and the energy conversion modules 15 are connected in series with each other, which can be used for power supply of sensors in overhead cable sections to optimize the energy utilization rate. The thermoelectric generator uses a Bi2Te3-based material.

[0035] Example 3: Refer to Figure 5 , which is basically the same as Example 2. Further: The transition layer 2 includes a sealing layer 23 fixed to the bottom surface of the outer protective layer 1. The bottom of the sealing layer 23 is fixedly connected to an isolation layer 22. The bottom of the isolation layer 22 is fixedly connected to a compressive layer 21. The bottom of the compressive layer 21 is fixedly connected to an interface layer 24. The sealing layer 23 is made of a fluororubber-aramid woven composite film material. The isolation layer 22 is made of silica aerogel material. A heat conduction member 221 is embedded in the isolation layer 22 to form a three-dimensional heat conduction barrier. The heat conduction member 221 is a silicon carbide nanowire. The isolation layer 22 is prepared by a sol-gel method with silica nanochains intertwined into a three-dimensional network with a porosity of 99.2%. The compressive layer 21 includes a high-density graphene foam layer 211 and a low-density graphene foam layer 212. The interface layer 24 is a boron nitride h-BN nanosheet coating. The gas transmission channel 3 is arranged in the compressive layer 21. The inner wall of the gas transmission channel 3 is provided with a heat insulation layer 31. The heat insulation layer 31 is a silica aerogel coating. The medium inside the gas transmission channel 3 is argon. Rubber sealing caps 7 are arranged at both ends of the gas transmission channel 3.

[0036] With the above solution, the sealing layer 23 is based on a fluororubber-aramid woven composite film to form a dual sealing system: the elasticity of the fluororubber compensates for the bending deformation of the optical cable, and the aramid fiber inhibits the expansion of cracks. The underlying isolation layer 22 is prepared by the sol-gel method, and the silica nanochains are intertwined into a three-dimensional network with a porosity of 99.2%, which has a good effect of reflecting infrared radiation. The compression layer 21 is gradient-composited by a high-density graphene foam layer 211 and a low-density graphene foam layer 212. The high-density layer with a porosity of 70% resists the instantaneous pressure of sand grain impact, and the low-density layer with a porosity of 90% absorbs vibration energy through elastic collapse. The gas transmission channel 3 is embedded inside the compression layer 21, and the heat insulation layer 31 on its inner wall blocks the interference of the heat exchange during the flow of argon gas to the optical fiber 6. Since the medium inside the gas transmission channel 3 is argon gas, the temperature difference between day and night on the surface of the optical cable forms a periodic bending stress, the sand foundation bed settles, and strong winds in the desert environment blow towards the optical cable, generating alternating vortices that shed behind the optical cable, triggering transverse vibrations and superimposing its own rotation. The force generated by the rotation drives the argon gas to flow inside the gas transmission channel 3, making the temperature difference across the cross-section of the optical cable more uniform, effectively improving the service life of the optical cable. Rubber seals 7 are then provided at both ends of the gas transmission channel 3, and a U-shaped tube is further arranged. The U-shaped tube is not located at the exposed end of the optical cable, but is embedded in the optical cable sheath. The U-shaped tube is made of a nickel-titanium alloy with shape memory characteristics, which deforms adaptively when the optical cable bends, and the head and tail are connected and communicated, so that the argon gas forms a circulating flow inside the gas transmission channel 3. Further, a micro air pump can be embedded and installed inside the gas transmission channel 3 to accelerate the flow of argon gas. The micro air pump is electrically connected and driven to operate by the stored electric energy. The interface layer 24 is used to quickly export the working heat of the optical fiber 6, and the chemical inertness of h-BN inhibits the attachment of microorganisms. The rubber seals 7 at both ends of the gas transmission channel 3 are made of a fluorosilicone rubber-carbon nanotube composite material to maintain the seal and prevent argon gas leakage.

[0037] Example 4: Refer to Figure 6 , which is basically the same as Example 3. Further, the repair layer 5 includes a UV-cured acrylic resin layer 501 fixed on the bottom surface of the isolation layer 22. Inside the UV-cured acrylic resin layer 501, there are repair capsules 503 and platinum catalyst nanoparticles 502, and a polyhexamethylene guanidine antibacterial coating 504 is fixed on the top of the UV-cured acrylic resin layer 501.

[0038] In the present invention, the UV-cured acrylic resin layer 501 serves as the matrix of the repair layer 5. Photosensitive groups (such as acrylate functional groups) are pre-polymerized in its molecular chain. Under the irradiation of desert ultraviolet rays, crosslinking and curing are rapidly completed to form a dense protective film. The repair capsules 503 uniformly distributed inside the resin layer encapsulate the silicone oligomer and the double-bond monomer. When microcracks are generated at the core-sheath of the optical fiber 6 due to stress, the stress concentration at the crack tip triggers the rupture of the repair capsules 503, releasing the repair agent into the crack. The platinum catalyst nanoparticles 502 act as free radical initiators to accelerate the hydrolysis and condensation reaction of the silicone in the repair agent, rapidly generating a three-dimensional silicone network to fill the crack, having a good self-repair effect, effectively saving human resources for maintenance work and reducing the maintenance cost. The polyhexamethylene guanidine antibacterial coating 504 is covalently anchored on the surface of the UV-cured acrylic resin layer 501. Its cationic polymer chain destroys the microbial cell membrane (such as the common halophilic bacteria in the desert) through electrostatic adsorption, having a good antibacterial effect and prolonging the service life of the optical cable.

[0039] The above embodiments only represent several implementation modes of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can be made. These are all equivalent modifications and evolutions of the above embodiments based on the essence of the present invention, and all belong to the protection scope of the present invention.
