Description

Technical Field

[0001] This invention relates to the field of network transmission cable technology, specifically a high-frequency insect- and ant-proof shielded network transmission cable. Background Technology

[0002] Currently, in scenarios such as building interconnection in industrial parks, community security monitoring, courtyard low-voltage network networking, and short-distance ground-to-ground interconnection in computer rooms, network transmission cables are generally laid using a short-distance direct burial method of 10-30 meters. Most conventional network cables on the market are of ordinary PVC sheath structure and lack specialized underground direct burial protection design. Directly laying them underground presents many technical defects in actual use, especially in damp, humus-rich soil, green belts, and garden soil environments, where the problems are more pronounced, as follows: 1. Poor resistance to insect and termite damage: Termites, ants, underground worms, mole crickets, and other insects are commonly found in underground soil. Conventional network cables only use ordinary PVC outer sheaths and lack insect-proof and termite-proof formulations and structural protection. Long-term gnaw and bore into the cable's outer sheath and insulation layer by insects and termites, easily causing sheath perforation, insulation damage, and short circuits in the conductors. Furthermore, insects and termites gnaw inward along cable seams, gradually destroying the twisted-pair structure, leading to increased network crosstalk, signal loss, and unstable network speed. Once a short-distance buried line of 10-30 meters is damaged by insects and termites, it directly paralyzes the entire communication link, resulting in high costs for subsequent investigation and re-excavation.

[0003] 2. Weak mechanical protection and insufficient resistance to external pressure and tension: Short-distance direct-buried cables of 10 to 30 meters often lack armor or pressure-resistant structures. Construction backfilling with stones, soil settlement, ground pedestrian and vehicle traffic, and freeze-thaw expansion and contraction of frozen soil can easily cause the cables to flatten, twist, and break the core wires. Conventional network cables cannot withstand the complex underground mechanical stress, resulting in a short service life.

[0004] To address the shortcomings of the existing technology, we provide a high-frequency insect- and ant-proof shielded network transmission cable to solve the aforementioned technical problems. Summary of the Invention

[0005] (a) Technical problems to be solved The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a high-frequency insect-proof shielded network transmission cable to solve the problems of poor insect resistance, weak mechanical protection, and short service life of existing direct-buried network cables.

[0006] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: A high-frequency insect- and ant-proof shielded network transmission cable includes: Battery cell; Inner sheath, which is fitted onto the battery cell, and spiral ribs are provided on the outer periphery of the inner sheath; An outer sheath is movably fitted onto the spiral rib. The outer sheath has multiple holes, and the inner wall of the outer sheath has multiple conical holes communicating with the holes. A void is formed between the outer sheath and the inner sheath, and a first sleeve and a second sleeve that communicate with the void are fitted on the outer sheath; Insect repellent is filled into the empty area through the first sleeve. The insect repellent is diverted through the holes into the soil outside the outer sheath to form a leaf-stem-shaped insect repellent. The insect repellent in the empty area forms a column-shaped functional protective layer.

[0007] First, the assembled network cable and the first and second sleeves are buried underground, and the feed joint of the feed pipe and the air outlet of the branch pipe are placed on the ground. Soil is laid on the outer sheath, and the outer sheath is pressed on the spiral ribs of the inner sheath, leaving space for subsequent filling of the empty area. The feed pipe is connected to an external peristaltic pump, which feeds the heated liquid insect repellent gel into the space between the outer and inner sheaths. The pressure in the space is discharged through the vent pipe of the second sleeve and the gap in the branch pipe, so that the space is in a depressurized state and the insect repellent gel can be well filled in the space. When the liquid insect repellent is filled into the exhaust pipe, some of the liquid insect repellent impacts the plug ball, causing the plug ball to move along the inner wall of the trumpet-shaped branch pipe until the plug ball seals the branch pipe. At this time, the empty area is in a closed pressure state. The feeding peristaltic pump continues to feed the liquid insect repellent. Under pressure, the insect repellent in the empty area flows through the conical hole and diffuses into the gaps of the filling soil to form leaf-stem-shaped insect repellent. After multiple leaf-stem-shaped insect repellents solidify, they are spirally and evenly distributed around the periphery of the outer sheath to repel insects and ants, effectively preventing insects and ants from approaching the outer sheath, thereby ensuring that the network cable is not bitten by insects and ants. The feed pipe is sealed, and the liquid insect repellent in the empty area solidifies to form a functional protective layer. This layer is placed between the outer and inner sheaths to form plastic protection. When soil subsidence or when pedestrians or vehicles run over the wires, the functional protective layer also provides a plastic buffering effect on the core, preventing it from being flattened or twisted, which could lead to core wire breakage. This enhances the network cable's ability to withstand complex underground mechanical stresses, ensuring its service life. Furthermore, it forms a column-shaped, fully enclosed insect repellent protective layer to prevent the inner sheath from being bitten by insects and ants, achieving multiple protective effects for the network cable.

[0008] This network cable has a simple overall structure design without any complex features, resulting in low manufacturing costs and good insect-proof performance.

[0009] Preferably, the plurality of holes and conical holes are distributed in a spiral pattern at equal intervals on the outer sheath.

[0010] Preferably, the functional protective layer is located between the outer sheath and the inner sheath.

[0011] Preferably, the inner circumference of the first sleeve is provided with a first cavity communicating with the empty area, and the first sleeve is provided with a feed pipe communicating with the first cavity.

[0012] Preferably, the feed inlet of the feed pipe is located on the ground, and a peristaltic pump is connected to the outside of the feed pipe.

[0013] Preferably, the inner circumference of the second sleeve is provided with a second cavity communicating with the empty area, and the second sleeve is provided with an exhaust pipe communicating with the second cavity.

[0014] Preferably, the exhaust pipe is connected to a branch pipe, and the outlet of the branch pipe is located on the ground.

[0015] Preferably, the branch pipe is trumpet-shaped, and the diameter of the branch pipe is gradually varied.

[0016] Preferably, the branch pipe is provided with an arc-shaped stop at its maximum diameter, and a plug ball that cooperates with the arc-shaped stop is provided inside the branch pipe, the diameter of the plug ball being larger than the minimum diameter of the branch pipe.

[0017] Preferably, when the ball stopper is located at the arc-shaped stopper of the branch pipe, a gap is formed between the ball stopper and the inner wall of the branch pipe, and the gap is connected to the exhaust pipe and the air outlet port of the branch pipe.

[0018] (III) Beneficial Effects Compared with the prior art, the present invention provides a high-frequency insect- and ant-proof shielded network transmission cable, which has the following beneficial effects: 1. This high-frequency insect-resistant shielded network transmission cable provides dual insect-repellent protection, preventing insect and ant damage and ensuring stable communication links. The invention utilizes the inner sheath's spiral ribs and the outer sheath to create a void. Relying on the synergistic effect of the first and second sheaths, it constructs a dual insect-resistant system with internal protection and an outer barrier. Combined with the filling and diversion of insect repellent adhesive, it achieves all-around protection. During construction, liquid insect repellent adhesive is filled into the void through the first sheath. After curing, it forms a columnar functional protective layer that completely encloses the inner sheath and the battery core, directly blocking the path of insects and ants to erode inwards. Simultaneously, under pressure, the insect repellent adhesive is diverted into the soil through the conical holes and pores of the outer sheath, forming a spirally distributed, leaf-stem-shaped insect repellent adhesive that creates a protective barrier around the cable, actively repelling insects and ants.

[0019] Compared to the shortcomings of traditional PVC sheathed cables lacking insect-proof design, this structure combines active insect repellency with passive protection, providing wide coverage and long-lasting insect-proof effects. It effectively solves the problem of termites, ants, and other insects in underground soil gnawing at the sheath and damaging the stranded core structure. It avoids faults such as sheath perforation, insulation damage, short circuits and open circuits in the core, signal crosstalk, and packet loss, preventing the entire short-distance direct-buried communication link from becoming paralyzed. This significantly reduces the maintenance costs of subsequent troubleshooting, excavation, and re-laying, ensuring stable transmission of high-frequency network signals. Furthermore, it eliminates the need for insect-proof formula modification of the sheath, simplifying the production process and controlling manufacturing costs.

[0020] 2. This high-frequency insect- and ant-bite resistant shielded network transmission cable features plastic buffer protection, enhancing mechanical performance and extending service life. This invention utilizes a functional protective layer formed by the curing of insect-repellent adhesive filling the voids, combined with the structural support of the inner sheath's spiral ribs, to construct a comprehensive mechanical buffer system that effectively resists complex underground mechanical stresses. When encountering external forces such as pressure from backfilled stones during construction, soil settlement, ground traffic from pedestrians and vehicles, and the stretching and contraction of frozen soil during freeze-thaw cycles, the column-shaped functional protective layer, with its excellent plasticity, buffers and disperses these forces, preventing the cable from being flattened or twisted, and preventing core wire breakage. The inner sheath's spiral ribs also enhance the structural strength of the inner sheath, further improving the cable's tensile and compressive strength.

[0021] This design addresses the industry pain points of traditional direct-buried cables, which lack armor and pressure-resistant structures, resulting in weak mechanical protection, susceptibility to external damage, and short service life. This structure eliminates the need for additional armor components, integrating mechanical protection and insect prevention through an insect-repellent protective layer. While simplifying the structure, it significantly enhances the cable's ability to withstand the mechanical stress of complex underground environments, making it suitable for various complex underground scenarios such as damp humus soil, green belts, and garden soil, thus significantly extending the cable's service life.

[0022] 3. This high-frequency insect-proof and ant-bite-resistant shielded network transmission cable features convenient filling construction, reducing construction difficulty and improving construction efficiency. This invention optimizes the design of the sleeve and pipeline, placing the feed pipe of the first sleeve and the air outlet of the branch pipe of the second sleeve on the ground. Combined with a peristaltic pump and an automatic sealing structure using a plug, it constructs a convenient and efficient insect repellent filling system. During construction, there is no need for repeated soil excavation; only feeding connection, filling observation, and sealing operations need to be completed on the ground. Air in the initial filling voids can be discharged through the gaps in the branch pipes, ensuring the insect repellent is filled densely without air bubbles. After filling, the plug automatically seals the branch pipes, achieving pressure closure in the voids and ensuring the insect repellent flows smoothly into the soil, eliminating the need for manual monitoring of the filling progress.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] This embodiment provides a high-frequency insect-proof and ant-bite-proof shielded network transmission cable with the following technical features.

[0037] Please see Figures 1 to 8 A high-frequency insect-proof and ant-bite-proof shielded network transmission cable, including a battery core 5; Inner sheath 4 is fitted onto the battery cell 5, and spiral ribs 41 are provided on the outer periphery of the inner sheath 4. It should be noted that: Cell 5 uses Category 6 unshielded twisted-pair cable for high-frequency network transmission. The core material is oxygen-free copper, and the twisting method is two-to-two twisting, with all four pairs of twisted wires twisted together. This effectively reduces signal crosstalk and ensures stable transmission of high-frequency signals up to 500MHz, meeting the needs of high-definition monitoring and high-speed data transmission in building interconnection within the park. The inner sheath 4 is made of wear-resistant, corrosion-resistant, and low-temperature-resistant modified PVC material with a Shore hardness of 85±5D. It is tightly fitted onto cell 5, providing initial insulation, moisture protection, and protection. The outer perimeter of the inner sheath 4 is integrally formed with spiral ribs 41. These spiral ribs 41 not only increase the structural strength of the inner sheath 4 and prevent it from being deformed by compression, but also create a uniform void 8 between the outer sheath 1 and the inner sheath 4, providing sufficient and uniform space for the insect repellent to fill, ensuring that the insect repellent can completely cover the inner sheath 4.

[0038] Outer sleeve 1, the outer sleeve 1 is movably sleeved on the spiral protrusion 41, the outer sleeve 1 is provided with multiple holes 11, and the inner wall of the outer sleeve 1 is provided with multiple conical holes 12 communicating with the holes 11. It should be noted that the conical hole 12 structure reduces the resistance when the insect repellent is diverted, making it easier for the insect repellent to flow smoothly through the hole 11 into the soil under pressure. The multiple holes 11 and conical holes 12 are distributed in a spiral pattern at equal intervals on the outer sheath 1 to ensure uniform diversion of the insect repellent, forming an all-round, no-dead-angle insect and ant barrier around the cable, avoiding blind spots in protection.

[0039] A void 8 is formed between the outer sheath 1 and the inner sheath 4. A first sleeve 2 and a second sleeve 3 that communicate with the void 8 are fitted on the outer sheath 1. The first head 2 fills the empty area 8 with insect repellent glue, which is then diverted through the holes 11 into the soil outside the outer sheath 1 to form leaf-stem-shaped insect repellent glue 7. The insect repellent glue in the empty area 8 forms a column-shaped functional protective layer 6.

[0040] First, the assembled network cable and the first sleeve 2 and the second sleeve 3 are buried underground, and the feed joint of the feed pipe 21 and the air outlet of the branch pipe 32 are placed on the ground. Soil is laid on the outer sheath 1, and the outer sheath 1 is pressed on the spiral rib 41 of the inner sheath 4, leaving space for subsequent filling of the empty area 8. The feed pipe 21, connected to an external peristaltic pump, feeds the heated liquid insect repellent gel into the cavity 8 between the outer sheath 1 and the inner sheath 4. The pressure in the cavity 8 is discharged through the exhaust pipe 31 of the second sleeve head 3 and the gap 34 in the branch pipe 32, so that the cavity 8 is in a depressurized state, allowing the insect repellent gel to fill the cavity 8 well. When the liquid insect repellent is filled into the exhaust pipe 31, some of the liquid insect repellent impacts the plug ball 33, causing the plug ball 33 to move along the inner wall of the trumpet-shaped branch pipe 32 until the plug ball 33 seals the branch pipe 32, achieving the self-sealing function of the branch pipe 32. At this time, the empty area 8 is in a closed pressure state, and the feeding peristaltic pump continues to feed the liquid insect repellent. Under pressure, the insect repellent in the empty area 8 flows through the conical hole 12 and diffuses through the hole 11 into the gap 34 of the filling soil to form leaf-stem-shaped insect repellent 7. After multiple leaf-stem-shaped insect repellents 7 are cured, they are spirally and evenly distributed around the periphery of the outer sheath 1 to achieve the purpose of repelling insects and ants, effectively preventing insects and ants from approaching the outer sheath 1, thereby ensuring that the network cable is not bitten by insects and ants. The feed pipe 21 is sealed, and the liquid insect repellent in the empty area 8 solidifies to form a functional protective layer 6, which is placed between the outer sheath 1 and the inner sheath 4 to form plastic protection. When soil subsidence or pedestrians and vehicles run over it, the functional protective layer 6 also provides a plastic buffer effect for the battery core 5, preventing it from being flattened or twisted, which could lead to core wire breakage. This enhances the ability of the network cable to withstand complex underground mechanical stress, ensures its service life, and further forms a column-shaped, fully enclosed insect repellent protective layer to prevent the inner sheath 4 from being bitten by insects and ants, thus achieving multiple protective effects for the network cable.

[0041] This network cable has a simple overall structure design without any complex features, resulting in low manufacturing costs and good insect-proof performance.

[0042] The insect repellent adhesive used in this embodiment is an environmentally friendly, long-lasting insect repellent formula. Its main components are natural plant extracts (peppermint oil, camphor oil), butyl rubber, and a curing agent. It is non-toxic, harmless, and odorless, and will not pollute the soil environment. It also has good adhesion and curing properties. The curing temperature is 25-30℃, the curing time is 2-3 hours, and the hardness after curing is 60±5D. It is not easy to fall off or be decomposed by the soil, and can achieve a long-term and stable insect and ant repellent effect. It can effectively repel termites, ants, underground worms, mole crickets, and other insects and ants in the underground soil.

[0043] Multiple holes 11 and conical holes 12 are distributed in a spiral pattern at equal intervals on the outer sheath 1.

[0044] The functional protective layer 6 is located between the outer sheath 1 and the inner sheath 4.

[0045] The first sleeve 2 has a first cavity that communicates with the empty area 8 inside, and a feed pipe 21 that communicates with the first cavity is provided on the first sleeve 2.

[0046] The feed inlet of feed pipe 21 is located on the ground, and a peristaltic pump is connected to the outside of feed pipe 21.

[0047] The inner circumference of the second sleeve head 3 is provided with a second cavity that communicates with the empty area 8, and the second sleeve head 3 is provided with an exhaust pipe 31 that communicates with the second cavity.

[0048] The exhaust pipe 31 is connected to a branch pipe 32, and the outlet of the branch pipe 32 is located on the ground.

[0049] Branch pipe 32 is trumpet-shaped, and its diameter is gradually varied.

[0050] The branch pipe 32 is equipped with an arc-shaped stop at its maximum diameter section, and a plug ball 33 that cooperates with the arc-shaped stop is installed inside the branch pipe 32. The diameter of the plug ball 33 is larger than the minimum diameter of the branch pipe 32.

[0051] When the ball stopper 33 is located at the arc-shaped stop of the branch pipe 32, a gap 34 is formed between the ball stopper 33 and the inner wall of the branch pipe 32, and the gap 34 is connected to the exhaust pipe 31 and the air outlet of the branch pipe 32.

[0052] It should be noted that: the branch pipe 32 is trumpet-shaped with a gradually changing diameter. The maximum diameter section of the branch pipe 32 has an arc-shaped stop. The plug ball 33 is made of elastic silicone material and has a diameter larger than the minimum diameter of the branch pipe 32. This ensures that the plug ball 33 can move flexibly within the branch pipe 32 and can effectively seal after filling, preventing the insect repellent from overflowing. When the plug ball 33 is located at the arc-shaped stop of the branch pipe 32, a gap 34 is formed between the plug ball 33 and the inner wall of the branch pipe 32. The gap 34 is connected to the exhaust pipe 31 and the air outlet of the branch pipe 32. In the initial filling stage, the air in the empty area 8 can be smoothly discharged through this gap 34, ensuring that the insect repellent can be evenly and densely filled into the empty area 8, avoiding the formation of air bubbles due to air residue, which would affect the protective effect of the functional protective layer 6.

[0053] Working principle: The first step is to bury the assembled network cable and the first and second connectors 2 and 3 underground, and place the feed inlet of the feed pipe 21 and the air outlet of the branch pipe 32 on the ground. Soil is laid on the outer sheath 1, and the outer sheath 1 is pressed on the spiral ribs 41 of the inner sheath 4, leaving space for subsequent filling of the empty area 8. The second step is to connect the feed pipe 21 to an external peristaltic pump. The heated liquid insect repellent gel is fed through the feed pipe 21 and the first cavity into the cavity 8 between the outer sheath 1 and the inner sheath 4. At this time, the air in the cavity 8 is discharged to the ground through the second cavity, the exhaust pipe 31, and the gap 34 in the branch pipe 32, so that the cavity 8 is in a depressurized state, ensuring that the insect repellent gel can be evenly and densely filled into the cavity 8. Third, when the liquid insect repellent is filled into the exhaust pipe 31, some of the liquid insect repellent impacts the plug ball 33, causing the plug ball 33 to move along the inner wall of the trumpet-shaped branch pipe 32 towards the end of the largest diameter pipe until the plug ball 33 fits against the arc-shaped stop of the branch pipe 32, completely sealing the branch pipe 32. At this time, the empty area 8 is in a closed pressure state. The feeding peristaltic pump continues to feed the liquid insect repellent. Under pressure, the insect repellent in the empty area 8 is diverted through the conical hole 12 and the hole 11 to the gap 34 of the filling soil, forming leaf-stem-shaped insect repellent 7. After multiple leaf-stem-shaped insect repellents 7 are cured, they are spirally and evenly distributed near the periphery of the outer sheath 1, forming an all-round insect and ant barrier, achieving the purpose of repelling insects and ants, effectively preventing insects and ants from approaching the outer sheath 1, thereby ensuring that the network cable is not bitten by insects and ants. The fourth step is to stop feeding and seal the feed pipe 21. The liquid insect repellent in the empty area 8 solidifies to form a column-shaped functional protective layer 6, which is placed between the outer sheath 1 and the inner sheath 4 to form plastic protection. When soil subsidence, pedestrians and vehicles run over it, or freeze-thaw expansion and contraction occur, the functional protective layer 6 provides a plastic buffer effect for the battery core 5, preventing it from being flattened or twisted, which could lead to core wire breakage. This enhances the ability of the network cable to withstand complex underground mechanical stress and ensures its service life. At the same time, the column-shaped functional protective layer 6 completely wraps around the inner sheath 4, further preventing the inner sheath 4 from being bitten by insects and ants, thus achieving multiple protective effects for the network cable.

[0054] In this embodiment, the insect repellent adhesive uses an environmentally friendly, long-lasting insect repellent formula that is non-toxic and harmless, and has good adhesion and curing properties. After curing, it is not easy to fall off or be decomposed by the soil, and can achieve a long-term insect and ant prevention effect. Both the outer sheath 1 and the inner sheath 4 are made of moisture-resistant and corrosion-resistant materials, which can adapt to complex environments such as underground damp humus soil, green belts, and garden soil, further extending the service life of the cable.

[0055] In summary, this high-frequency insect- and ant-resistant shielded network transmission cable aims to solve the problems of poor insect and ant resistance, weak mechanical protection, and short service life of existing direct-buried network cables. Insect repellent is filled into the empty area 8 through the first sleeve 2. The insect repellent is then distributed into the soil through the holes 11, forming a leaf-stem-shaped insect repellent 7. Within the empty area 8, the insect repellent forms a column-shaped functional protective layer 6. This invention achieves all-round insect and ant protection through the dual distribution of the insect repellent. The plasticity of the functional protective layer 6 also provides good mechanical buffering. The structure is simple, the manufacturing cost is low, and the construction is convenient. It is suitable for short-distance direct burial scenarios of 10-30 meters, effectively extending the cable's service life and reducing maintenance costs.
