Description

Technical Field

[0001] This utility model relates to the field of bundled pipe technology, and in particular to a bundled pipe for overhead laying. Background Technology

[0002] Overhead cabling is a method of laying cables, pipes, and other facilities above the ground. It is widely used in power transmission and communication, such as urban power grid upgrades, communication base station cable laying, and railway electrification projects. It primarily relies on supporting structures such as utility poles and towers to keep the cables or pipes a certain distance from the ground. This method offers many advantages, avoiding damage caused by ground construction, reducing conflicts with other underground facilities, and lowering maintenance difficulty and costs.

[0003] Overhead cable bundled conduits are a new type of conduit used for overhead cable laying. Generally made of high-quality plastic materials, they are corrosion-resistant, aging-resistant, and have good insulation properties. Compared to traditional direct burial or pipe laying, their overhead laying method offers advantages such as convenient construction, lower cost, and easier maintenance and repair. During overhead laying, bundled conduits can place multiple cables in different sub-conduits, protecting the cables and preventing mutual interference. They also effectively prevent damage to the cables from external environmental factors. Furthermore, bundled conduits have a neat and aesthetically pleasing appearance, enhancing the overall image of overhead lines. They are widely used in the construction of overhead lines in fields such as communications and power, providing an efficient and reliable cable protection and laying solution.

[0004] Currently, overhead cable laying commonly employs single-cable independent suspension or simple bundling. With the increasing demand for intensive urban space utilization, the need for integrated multi-cable laying has significantly increased. Traditional PVC or PE protective conduits, due to insufficient tensile strength and susceptibility to aging, cannot meet the mechanical performance and insulation requirements for mixed laying of high-voltage cables and communication optical cables. In recent years, composite material conduits (such as fiberglass) have partially solved the strength problem, but suffer from drawbacks such as heavy weight and limited bending radius, leading to low construction efficiency and high costs. Metal armored conduits, with spiral steel strip winding to enhance compressive strength, have problems such as electromagnetic shielding interference with communication signals and susceptibility to corrosion. Split-type plastic corrugated pipes, using multiple independent corrugated pipes connected in parallel with clips, reduce weight but are prone to water leakage at joints and have poor wind resistance. Integral extruded HDPE bundled pipes, with multiple cavities formed in one piece, suffer from poor wall thickness uniformity and localized stress concentration leading to cracking. Therefore, to address these shortcomings, a bundled pipe for overhead laying is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a bundled pipe for overhead laying, which aims to improve the problem that some bundled pipes in the prior art have poor protection effect and cannot effectively resist wind and water.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a bundled pipe for overhead laying, comprising an outer sheath, wherein a protective mechanism is provided inside the outer sheath, and a separation mechanism is provided inside the protective mechanism; the protective mechanism includes a wind-resistant mechanism, the wind-resistant mechanism is fixedly connected to the outside of the outer sheath, a wear-resistant layer is fixedly connected to the outside of the outer sheath, an anti-ultraviolet coating is fixedly connected to the outside of the wear-resistant layer, an isolation liner is fixedly connected to the inner wall of the wind-resistant mechanism, and a shielding layer is fixedly connected to the inner wall of the isolation liner.

[0007] Through the above technical solution: the wind-resistant mechanism in the protective structure is fixed inside the outer sheath. The outer sheath is connected in sequence with a wear-resistant layer and a UV-resistant coating. The inner wall of the wind-resistant mechanism is connected in sequence with an isolation liner and a shielding layer. In an outdoor overhead environment, the UV-resistant coating blocks ultraviolet rays, reducing the aging of the bundle tube due to sunlight. The wear-resistant layer resists external friction, reducing the risk of wear. The aramid fiber braided mesh and modified polyurethane in the wind-resistant mechanism work together to disperse wind stress and absorb vibration energy, ensuring the stability of the bundle tube in the wind. The isolation liner expands when exposed to water to seal micro-cracks, preventing moisture intrusion. The shielding layer shields electromagnetic interference, ensuring the normal operation of the internal cables. The combined effect of these structures improves the applicability and safety of the bundle tube in complex outdoor environments.

[0008] As a further description of the above technical solution:

[0009] The partitioning mechanism includes multiple cavity partitions, which are externally slidably connected to the inside of the outer sheath. T-shaped slide rails are fixedly connected to the opposite sides of the multiple cavity partitions. Multiple cables are installed inside the outer sheath, and multiple dovetail grooves are opened inside the outer sheath.

[0010] Through the above technical solution: when the cable is inserted into the bundle tube, the partition plate is displaced by the cable compression. The T-shaped slide rails at both ends slide in the dovetail groove, driving the partition plate to move and adjust its position. This movement process allows the partition plate to adaptively change the shape and volume of the tube according to the cable diameter, realizing the separation and fixation of cables of different diameters, avoiding mutual compression and friction between cables, effectively improving the bundle tube's adaptability to accommodate various cables, and ensuring the stability and safety of the cables in the bundle tube.

[0011] As a further description of the above technical solution:

[0012] The wind-resistant mechanism includes a modified polyurethane layer, the outside of which is fixedly connected to the inside of the outer sheath, and an aramid fiber woven mesh is fixedly connected to the inside of the modified polyurethane layer.

[0013] The above technical solution involves a wind-resistant mechanism composed of a modified polyurethane layer and an aramid fiber braided mesh. The modified polyurethane layer is externally and internally fixed to the outer sheath, while internally it is fixed to the aramid fiber braided mesh. Under wind load, it disperses the stress brought by the wind through its own shear deformation. The modified polyurethane layer fills the gaps in the aramid fiber braided mesh, and its matrix has good elasticity. When the aramid fibers disperse stress, they absorb vibration energy. The two work together to effectively reduce the vibration amplitude of the bundled tube in the wind, enhance the wind resistance of the bundled tube, and ensure that the bundled tube can maintain structural stability even when encountering strong winds during overhead installation, reducing damage to the internal cables and its own structure caused by wind-induced vibration.

[0014] As a further description of the above technical solution:

[0015] The aramid fiber woven mesh is woven at a 45° angle with a weaving density of ≥12 bundles / cm², and the height of the partition plate is adjustable from 10 to 25 mm.

[0016] Through the above technical solution: In the bundled tube, the aramid fiber braided mesh is cross-woven at 45° with a weaving density ≥12 bundles / cm², and the height of the partition plate is adjustable from 10-25mm. When the bundled tube is subjected to wind load, the special weaving structure of the aramid fiber braided mesh allows the fibers in all directions to synergistically generate shear deformation under the action of wind, effectively dispersing stress, thereby reducing the degree of swaying and deformation of the bundled tube in the wind and improving wind resistance. The height of the partition plate can be adjusted according to the cable diameter by sliding in the dovetail groove through the T-shaped slide rails at both ends, flexibly changing within the range of 10-25mm to meet the needs of cables of different diameters, achieving a tight fit and stable separation of the cables, avoiding mutual compression and friction between the cables, and ensuring the normal operation of the cables.

[0017] As a further description of the above technical solution:

[0018] The dovetail grooves are arranged in a circular array inside the outer sheath, and the external T-shaped slide rail is slidably connected to the inside of the dovetail grooves.

[0019] Through the above technical solution, the T-shaped slide rail can slide smoothly in multiple directions, guiding the compartment partition to make precise position adjustments. This movement process realizes the flexible movement of the compartment partition, enabling the compartment partition to adaptively change the shape and volume of the cavity according to the actual situation of the cable, thereby effectively separating and fixing cables of different diameters, improving the adaptability of the bundle tube to various cables, and ensuring the orderly arrangement and safe operation of cables in the bundle tube.

[0020] As a further description of the above technical solution:

[0021] The outer side of the partition plate is in contact with the outer side of the cable, and the outer side of the partition plate is slidably connected to the outer side of the isolation liner.

[0022] The above technical solution works as follows: when cables of different diameters are inserted into the bundle tube, the cables exert pressure on the partition plate, causing the partition plate to slide outside the isolation liner. During the sliding process, the partition plate adaptively adjusts its position according to the cable diameter, achieving separation and protection of the cables by tightly fitting them together, thus preventing the cables from squeezing or rubbing against each other.

[0023] As a further description of the above technical solution:

[0024] The external cavity partition is slidably connected to the outside of the shielding layer, and the external T-shaped slide rail is slidably connected to the outside of the modified polyurethane layer.

[0025] Through the above technical solution: when it is necessary to adjust the cavity to accommodate cables of different diameters, the cavity partition will be displaced under the action of external force. Since its exterior is slidably connected to the shielding layer, the cavity partition can slide smoothly along the surface of the shielding layer, ensuring that the shielding layer will not be damaged during cavity adjustment, and maintaining the shielding layer's function of reducing electromagnetic interference.

[0026] As a further description of the above technical solution:

[0027] The outer sheath is co-extruded to cover the wind-resistant mechanism, and the partition plate is joined by tenon and mortise to form 3 to 6 variable diameter cavities.

[0028] Through the above technical solution: during use, the aramid fiber braided mesh and modified polyurethane in the wind-resistant mechanism work together to resist wind loads and ensure the stability of the bundled tube. When laying cables, cables of different diameters are inserted into the bundled tube, and the partition is squeezed by the cables. Due to the flexibility of the tenon and mortise joint structure, the partition can adaptively adjust its position and tube shape to form a variable diameter tube that closely fits cables of different diameters, achieving effective separation and protection of the cables, avoiding mutual squeezing and friction between the cables, and improving the bundled tube's adaptability and protection capability for different cables.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the outer sheath of the bundled tube is made of weather-resistant TPU material with a Shore hardness of 85D, giving it good strength and toughness. It can effectively resist external mechanical impacts and has a UV resistance level of ≥8, preventing aging and discoloration caused by ultraviolet rays. In the wind-resistant mechanism, the aramid fiber braided mesh is woven at a 45° angle with a braiding density of ≥12 bundles / cm². Combined with modified polyurethane, the aramid fibers disperse stress under wind load, and the polyurethane absorbs vibration energy, significantly improving wind resistance. At the same time, the water-swellable isolation liner can seal micro-cracks, prevent moisture intrusion, and ensure the insulation performance of the cable. These structures work together to greatly improve the overall performance of the bundled tube, providing better protection in terms of strength, wind resistance, and waterproofing, and solving many defects of traditional bundled tubes.

[0031] 2. In this utility model, the partition plate forms 3-6 variable-diameter cavities through mortise and tenon joints. It is made of fiberglass-reinforced PP material with a thickness of 2.5mm, ensuring structural strength and cavity stability. The T-shaped slide rails at both ends of the partition plate slide in conjunction with the dovetail grooves on the inner wall of the outer sheath. The height is adjustable from 10-25mm, and the T-shaped slide rail tolerance is ±0.1mm, ensuring adjustment accuracy. When cables are inserted, the partition plate can adaptively adjust its position according to the cable diameter. Under pressure, it finely adjusts the cavity volume through the slide rails, achieving precise fixing and separation of cables of different diameters. This avoids mutual squeezing and friction between cables, improving the adaptability of the bundled tube to different cable laying requirements. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figures 1 to 3 One embodiment of this utility model is a bundled pipe for overhead laying, including an outer sheath 1. The outer sheath 1 is the outermost structure of the bundled pipe. It is tightly combined with the wind-resistant mechanism 21 by co-extrusion process. The material is weather-resistant TPU with a Shore hardness of 85D and a UV resistance level of ≥8. It has good weather resistance and can be used for a long time in complex outdoor environments. The Shore hardness of 85D gives it a certain degree of hardness and toughness, making it difficult to be easily damaged by external forces. The UV resistance level of ≥8 ensures that it will not age, discolor, or degrade in performance under ultraviolet radiation. The main function of the outer sheath 1 is to provide overall protection for the bundle tube, resisting external mechanical impacts, rainwater erosion, etc. The outer sheath 1 has a protective mechanism 2 inside, and the protective mechanism 2 has a separation mechanism 3 inside. The protective mechanism 2 includes a wind-resistant mechanism 21. The outer sheath 1 is coated with the wind-resistant mechanism 21 using a co-extrusion process. The wind-resistant mechanism 21 includes a modified polyurethane layer 2101. The modified polyurethane layer 2101 is externally fixed to the inside of the outer sheath 1. The modified polyurethane layer 2101 fills the gaps in the aramid fiber woven mesh 2102 and is cured. On the one hand, it fixes the aramid fibers. On the other hand, the polyurethane matrix has good elasticity and can absorb vibration energy, reducing the vibration of the bundle tube in the wind, thereby improving the wind resistance of the bundle tube.

[0040] An aramid fiber woven mesh 2102 is internally fixedly connected to the modified polyurethane layer 2101. The aramid fiber woven mesh 2102 is woven at a 45° angle with a weaving density of ≥12 bundles / cm². This weaving method allows the aramid fibers to effectively disperse stress in all directions. Aramid fibers have high strength and high modulus, and can withstand large tensile forces. Under wind load, they disperse the stress generated by wind force through their own shear deformation. The wind-resistant mechanism 21 is externally fixedly connected to the inside of the outer sheath 1. A wear-resistant layer 22 is externally fixedly connected to the outside of the outer sheath 1. The wear-resistant layer 22 enhances the wear resistance of the bundle tube and effectively reduces the damage caused by friction to the bundle tube, extending its service life. An anti-ultraviolet coating 23 is externally fixedly connected to the outside of the wear-resistant layer 22. The anti-ultraviolet coating 23 enhances the anti-ultraviolet capability of the bundle tube. Ultraviolet rays will cause material aging and performance degradation. The anti-ultraviolet coating 23 effectively blocks ultraviolet rays, protecting the internal structure and cable 33 of the bundle tube from ultraviolet rays. To protect against external interference and maintain the stability of the bundle tube's performance, the wind-resistant mechanism 21 has an isolation liner 24 fixedly connected to its inner wall. The material of the isolation liner 24 has the property of expanding when exposed to water. When rainwater seeps into the bundle tube, the isolation liner 24 expands upon contact with water, sealing micro-cracks and preventing further water intrusion. This protects the internal cables 33 from water erosion and ensures the insulation performance and normal operation of the cables 33. The inner wall of the isolation liner 24 is also fixedly connected to a shielding layer 25. The shielding layer 25 reduces electromagnetic interference. In scenarios where power transmission and communication cables 33 are laid together, electromagnetic interference will occur between different cables 33. The shielding layer 25 can effectively shield these interference signals, ensuring the signal transmission quality of the communication cables 33 and the normal operation of the power cables 33.

[0041] Specifically, the outer sheath 1 is tightly integrated with the wind-resistant mechanism 21 using a co-extrusion process. Its weather-resistant TPU material has a Shore hardness of 85D and a UV resistance rating of ≥8, giving it excellent weather resistance and enabling it to withstand mechanical impact and rainwater erosion, providing overall protection for the bundled tubes. The wind-resistant mechanism 21 in the protective mechanism 2 has a modified polyurethane layer 2101 filled with and fixed an aramid fiber woven mesh 2102. The aramid fiber woven mesh 2102 is woven at a 45° angle with a weaving density of ≥12 bundles / cm². Under wind load, the aramid fibers disperse stress through shear deformation, and the polyurethane matrix absorbs vibration energy, improving wind resistance. The wear-resistant layer 22 outside the outer sheath 1 reduces friction damage and extends service life. The UV-resistant coating 23 blocks ultraviolet rays to maintain the stable performance of the bundle tube. The isolation lining 24 on the inner wall of the wind-resistant mechanism 21 expands when exposed to water to seal micro-cracks, preventing moisture intrusion and protecting the insulation performance of the cable 33. The shielding layer 25 shields electromagnetic interference and ensures the normal operation of the cable 33. Under the influence of various complex outdoor environmental factors, the various structures move in coordination, effectively improving the comprehensive performance of the bundle tube in terms of mechanical properties, insulation, wind resistance, waterproofing, UV resistance and compatibility with different cables 33, ensuring the safe and stable operation of the cable 33 inside the bundle tube.

[0042] Reference Figures 2 to 4 The partition mechanism 3 includes multiple partition plates 31. The partition plates 31 are externally slidably connected to the inside of the outer sheath 1. The height of the partition plates 31 is adjustable from 10 to 25 mm. The partition plates 31 form 3 to 6 variable diameter cavities through tenon and mortise joints. The partition plates 31 are made of glass fiber reinforced PP material with a thickness of 2.5 mm. Glass fiber reinforced PP has high strength and rigidity, which can withstand the pressure of the cable 33 and ensure the stability of the cavity shape. The partition plates 31 are externally slidably connected to the outside of the isolation liner 24 and the outside of the shielding layer 25. T-shaped slide rails 32 are fixedly connected to the opposite sides of the multiple partition plates 31. The design of the T-shaped slide rails 32 allows the partition plates 31 to slide smoothly in the dovetail groove 34 with a tolerance controlled within ±0.1 mm, ensuring the accuracy and stability of the sliding of the partition plates 31 and enabling the partition plates 31 to be accurately positioned when adjusting the cavity volume.

[0043] The T-shaped slide rail 32 is externally slidably connected to the outside of the modified polyurethane layer 2101. Multiple cables 33 are arranged inside the outer sheath 1. When the cables 33 are inserted, the partition plate 31 is compressed. The T-shaped slide rail 32 at both ends slides and finely adjusts in the dovetail groove 34 to balance the volume of the tube. This achieves tight fit and separation protection for cables 33 of different diameters, avoiding mutual squeezing and friction between the cables 33. The outside of the partition plate 31 is in contact with the outside of the cables 33. Multiple dovetail grooves 34 are opened inside the outer sheath 1. The dovetail grooves 34 are arranged in a ring array inside the outer sheath 1. The T-shaped slide rail 32 is externally slidably connected to the inside of the dovetail grooves 34. The dovetail grooves 34 and the T-shaped slide rail 32 cooperate with each other to provide guidance and support for the T-shaped slide rail 32, ensuring that the partition plate 31 can slide along the set trajectory to achieve dynamic adjustment of the volume of the tube. At the same time, it also enhances the connection stability between the partition plate 31 and the outer sheath 1.

[0044] Specifically, the partition plate 31 is made of glass fiber reinforced PP material with a thickness of 2.5mm. It forms 3-6 variable diameter cavities through tenon and mortise joints, with an adjustable height range of 10-25mm. It is externally slidably connected to the outer sheath 1, the isolation liner 24 and the shielding layer 25. The opposite side is fixedly connected to the T-shaped slide rail 32. The outer sheath 1 has dovetail grooves 34 arranged in a ring array inside. The T-shaped slide rail 32 and the dovetail grooves 34 slide in fit, with the tolerance controlled within ±0.1mm. When the cable 33 is inserted into the bundle tube, the partition plate 31 is subjected to the pressure of the cable 33 and slides and finely adjusts in the dovetail groove 34 via the T-shaped slide rail 32. During this movement, the partition plate 31 adaptively adjusts its position according to the diameter of the cable 33, and uses its variable diameter tube to achieve close fit and separation of cables 33 of different diameters, avoiding mutual squeezing and friction of the cables 33. At the same time, the cooperation between the dovetail groove 34 and the T-shaped slide rail 32 not only provides guidance and support for the sliding of the partition plate 31 and realizes dynamic adjustment of the tube volume, but also enhances the connection stability between the partition plate 31 and the outer sheath 1, ensuring the efficient accommodation and safe protection of various cables 33 in the bundle tube, and improving the adaptability and reliability of the bundle tube in the cable 33 laying scenario.

[0045] Working Principle: In this bundled tube, the outer sheath 1 is co-extruded to cover the wind-resistant mechanism 21. The aramid fiber woven mesh 2102 in the wind-resistant mechanism 21 is cross-woven at 45° with a weaving density ≥12 bundles / cm², and is composited with modified polyurethane. Under wind load, the aramid fiber mesh disperses stress through shear deformation, and the polyurethane matrix absorbs vibration energy, thus playing a wind-resistant role. The outer wear-resistant layer 22 and the UV-resistant coating 23 enhance the wear resistance and UV resistance of the bundled tube, respectively. The inner isolation liner 24 expands when exposed to water to seal micro-cracks, and the shielding layer 25 reduces electromagnetic interference. The partition plate 31 of the separation mechanism 3 forms 3-6 variable diameter cavities through tenon and mortise joints. The T-shaped slide rails 32 at both ends slide in conjunction with the dovetail grooves 34 on the inner wall of the outer sheath 1. The height is adjustable from 10 to 25 mm. When the cable 33 is inserted, the partition plate 31 adjusts its position according to the cable diameter. After being compressed, the volume of the cavity is balanced by fine adjustment of the slide rails, so as to achieve separation and protection of cables 33 of different diameters. Compared with the existing technology, it effectively solves the problems of mechanical performance, insulation, compatibility and sealing of traditional bundled tubes.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
