Description

Technical Field

[0001] This application relates to the field of cable protection pipe technology, and in particular to an impact-resistant reinforced cable protection pipe. Background Technology

[0002] Cable protection pipes are tubular protective components used to wrap power and communication cables. They are widely used in underground pipe laying, building wiring and outdoor wiring. Their core function is to isolate soil corrosion, mechanical scratches and water erosion. Conventional products are mostly made of plastic and metal in one piece, relying on the pipe body structure to isolate the external environment and provide physical isolation protection for the internal cables.

[0003] However, most existing cable protection pipes are single-layer structures. Single-layer cable protection pipes lack a graded buffer and energy absorption structure. When subjected to impacts such as heavy objects or soil compaction, the pipes are prone to cracking due to stress concentration. Furthermore, due to the lack of multi-layer energy absorption components, the impact load may be directly transmitted to the internal cables, potentially causing damage to the cable insulation layer. In addition, conventional cable protection pipes lack anti-slip structures on the outer wall, have a relatively large overall weight, and are prone to slippage and displacement after burial. They also have poor compressive and bending resistance, resulting in a short service life under heavy load conditions, and cannot meet the requirements for high-strength impact-resistant laying. Summary of the Invention

[0004] Therefore, it is necessary to provide an impact-resistant reinforced cable protection pipe to address the aforementioned technical problems.

[0005] The impact-resistant reinforced cable protection pipe provided in this application adopts the following technical solution: it includes an integrated sleeve, a cable is provided inside the integrated sleeve, an elastic mechanism is connected to the outside of the integrated sleeve through a support ring, a middle sleeve is provided outside the elastic mechanism, an energy-absorbing sleeve is provided outside the middle sleeve, and an outer sleeve is connected to the outside of the energy-absorbing sleeve.

[0006] The elastic mechanism includes a fixed sleeve, an inner hole, and a buffer mechanism. The outer side of the support ring is provided with a fixed sleeve. The inner end of the fixed sleeve is connected to the support ring through the inner hole. There are not less than two sets of buffer mechanisms connected to the outer side of the fixed sleeve.

[0007] By adopting the above technical solution, the cable is protected by an integrated sleeve. The elastic mechanism is supported by a support ring and forms a multi-layer composite protective structure with the middle sleeve, energy-absorbing sleeve and outer sleeve. At the same time, the fixed sleeve block of the elastic mechanism cooperates with the support ring through the inner hole and carries multiple sets of buffer mechanisms, so that external impacts can be dispersed and absorbed layer by layer, effectively enhancing the overall impact resistance of the pipe.

[0008] Preferably, the buffer mechanism includes a first buffer sleeve, a buffer shell, a second buffer sleeve, and buffer rings. At least two sets of first buffer sleeves are provided at equal intervals on the outer side of the fixed sleeve block. A set of buffer shells is connected to the other end of the first buffer sleeve. Two sets of second buffer sleeves are arranged radially on the side of the buffer shell close to the first buffer sleeve. At least two sets of buffer rings are provided inside the buffer shell.

[0009] By adopting the above technical solution, the buffer mechanism uses buffer sleeve one and buffer sleeve two to provide multi-level elastic support. Combined with the graded deformation of the buffer shell and buffer ring, it can quickly dissipate impact energy, making the buffer energy absorption effect of the elastic mechanism more uniform and reliable.

[0010] Preferably, the buffer shell includes a front layer and a rear shell, the ends of the first and second buffer sleeves away from the fixed sleeve block are connected to the rear shell, and the end of the rear shell away from the first buffer sleeve is connected to the front layer.

[0011] By adopting the above technical solution, the impact force can first be absorbed and diffused by the front layer, and then transferred to the rear shell and buffer sleeve one and buffer sleeve two by the buffer ring, so as to achieve layered buffering and effectively improve the impact resistance and energy absorption layer of the buffer shell.

[0012] Preferably, the inner side of the outer jacket has at least two sets of reinforcing ribs arranged in a circular pattern, the inner side of the outer jacket has at least two sets of reinforcing rings arranged axially, and the outer side of the outer jacket has an outer texture.

[0013] By adopting the above technical solutions, the combination of reinforcing ribs and reinforcing rings can significantly improve the radial compressive strength and axial bending strength of the outer jacket. The outer texture of the outer jacket can increase surface friction and gripping force, which can prevent displacement after laying and improve the protection and installation stability of the outer jacket.

[0014] Preferably, the energy-absorbing sleeve is a honeycomb structure sleeve.

[0015] By adopting the above technical solution, the plastic deformation and elastic buckling of the honeycomb pore walls can be used to fully absorb impact energy, while reducing the weight of the tube, thus achieving a balance between high-efficiency energy absorption and lightweight design.

[0016] Preferably, the rear housing is made of a rigid material, and the front layer is made of an elastic material.

[0017] By adopting the above technical solution, the rear shell is made of rigid material to ensure support rigidity, while the front layer is made of elastic material to achieve flexible buffering. This combination of rigidity and flexibility in the buffer shell can effectively attenuate impact force and enhance the protection effect on cables.

[0018] Preferably, the first and second buffer sleeves have built-in buffer springs.

[0019] By adopting the above technical solutions, the elastic reset capability and dynamic energy absorption amplitude of the buffer mechanism can be improved, making the buffer response faster and having the ability to withstand repeated impacts.

[0020] Preferably, the fixing block has a regular hexagonal structure.

[0021] By adopting the above technical solution, the regular hexagonal structure facilitates the close splicing and regular arrangement of multiple buffer mechanisms in the circumferential direction, effectively enhancing the overall uniformity of force distribution, torsional resistance and space utilization of the elastic mechanism.

[0022] Preferably, the outer side of the integrated sleeve is axially arranged with at least two sets of support rings.

[0023] By adopting the above technical solutions, continuous support at multiple points can be formed, so that the load on the elastic mechanism can be uniformly transmitted and dispersed along the axial direction, avoiding local stress concentration and improving the overall structural consistency and deformation resistance of the protective pipe.

[0024] Preferably, the support ring has a hollowed-out groove at its middle end.

[0025] By adopting the above technical solution, the hollowed-out groove helps to reduce the self-weight of the support ring and provides a certain flexible clearance space when subjected to impact, thus optimizing the force transmission path.

[0026] In summary, this application includes the following beneficial technical effects:

[0027] 1. This application, through the support ring and elastic mechanism set on the outside of the integrated sleeve, combined with the middle sleeve, energy-absorbing sleeve and outer sleeve, can form a multi-layer composite protection system. The hexagonal fixed sleeve block inside the elastic mechanism can carry multiple sets of spring-loaded buffer sleeve one and buffer sleeve two. Combined with the soft and hard layered buffer shell and the internal buffer ring, multi-level flexible buffering can be achieved. External impacts are dissipated layer by layer through elastic deformation. Compared with traditional single-layer pipes, it can effectively avoid stress concentration and greatly improve the overall impact resistance of the cable protection pipe. Moreover, the buffer component has elastic reset performance, can withstand multiple impacts without failure, and has a long service life.

[0028] 2. This application uses a honeycomb structure energy-absorbing sleeve and a buffer shell with different materials on the inner and outer sides. With the cooperation of both, the energy-absorbing sleeve absorbs residual impact energy by plastic deformation of the honeycomb hole wall, while reducing the weight of the cable protection pipe. In the buffer shell, the rigid rear shell can provide rigid support, and the elastic front layer can achieve initial flexible force relief. The rigid-flexible coupling energy-absorbing structure can effectively make up for the shortcomings of traditional pipes that rely solely on the hardness of the material to resist impact, and achieve both lightweight and high strength under the same wall thickness conditions.

[0029] 3. This application uses circumferentially arranged reinforcing ribs on the inner side of the outer casing and axially arranged reinforcing rings to form an integrated reinforced and anti-slip structure with the outer texture of the outer casing. The reinforcing ribs and reinforcing rings combine to form a cage-like support skeleton, which simultaneously improves the radial compressive strength and axial bending strength of the outer casing. The outer texture of the outer wall can increase the gripping friction with the backfill soil, prevent the pipe from slipping and misaligning after being buried, solve the problems of insufficient pressure difference and laying stability of existing protective pipes, and is not prone to displacement and deformation after long-term use.

[0030] 4. This application uses multiple sets of support rings axially arranged on the outside of the integrated sleeve to evenly distribute the load borne by the elastic mechanism along the axial direction. The support rings have hollowed-out grooves, which can further reduce the overall weight of the pipe, while reserving space for stress relief, optimizing the impact load transmission path, avoiding pipe cracking caused by local stress concentration, and improving the axial structural consistency and deformation resistance of the entire protective pipe.

[0039] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0040] An impact-resistant reinforced cable protection pipe, as described in the reference Figure 1 , Figure 2 and Figure 5 The system includes an integrated sleeve 1, which integrates at least two sets of cables 2 for initial protection. At least two sets of support rings 3 are axially arranged on the outer side of the integrated sleeve 1, and elastic mechanisms 4 are connected to the support rings 3. This forms continuous support at multiple points, ensuring that the load on the elastic mechanism 4 is evenly transmitted and distributed axially, avoiding local stress concentration, and improving the overall structural consistency and deformation resistance of the protective tube. The support rings 3 have a hollowed-out groove in the middle, which helps reduce the weight of the support rings 3 and provides some flexible clearance space under impact, optimizing the force transmission path. The elastic mechanism 4 has a middle sleeve 5 on the outside, and an energy-absorbing sleeve 6 on the outside of the middle sleeve 5. The energy-absorbing sleeve 6 is a honeycomb structure sleeve, which can fully absorb impact energy by utilizing the plastic deformation and elastic buckling of the honeycomb hole wall, while reducing the weight of the tube body, thus achieving a balance between high-efficiency energy absorption and lightweight. An outer sleeve 7 is connected to the outside of the energy-absorbing sleeve 6. Furthermore, the elastic mechanism 4 includes a fixed sleeve block 41, an inner hole 42, and a buffer mechanism 43. Fixed sleeve blocks 41 are provided on the outside of the support ring 3. The inner end of the fixed sleeve block 41 is connected to the support ring 3 through the inner hole 42. At least two sets of buffer mechanisms 43 are connected to the outside of the fixed sleeve block 41.

[0041] Specifically, the integrated sleeve 1 is used to protect the cable 2. The elastic mechanism 4 is supported by the support ring 3 and forms a multi-layer composite protective structure with the middle sleeve 5, the energy-absorbing sleeve 6 and the outer sleeve 7. At the same time, the fixing block 41 of the elastic mechanism 4 cooperates with the support ring 3 through the inner hole 42 and carries multiple sets of buffer mechanisms 43, so that external impacts can be dispersed and absorbed layer by layer, effectively enhancing the overall impact resistance of the pipe.

[0042] An impact-resistant reinforced cable protection pipe, as described in the reference Figures 2-3The buffer mechanism 43 includes a first buffer sleeve 431, a buffer shell 432, a second buffer sleeve 433, and a buffer ring 434. The fixed block 41 has a regular hexagonal structure, which facilitates the tight splicing and regular arrangement of the buffer mechanism 43 in the circumferential direction, effectively enhancing the overall uniformity of force distribution, torsional resistance, and space utilization of the elastic mechanism 4. Each plane on the outer side of the fixed block 41 is provided with a set of first buffer sleeves 431. The other end of the first buffer sleeve 431 is connected to a set of buffer shells 432. Two sets of second buffer sleeves 433 are arranged radially on the side of the buffer shell 432 near the first buffer sleeve 431. The first buffer sleeve 431 is located between the two sets of buffer sleeves. Between the two sleeves 433, the buffer shell 432 is supported and connected together. The buffer sleeve 431 and the buffer sleeve 433 have built-in buffer springs, which can improve the elastic restoring ability and dynamic energy absorption amplitude of the buffer mechanism 43, making the buffer response faster and having repeated impact resistance. Each buffer shell 432 is provided with no less than two sets of buffer rings 434. The buffer rings 434 are made of elastic material. When the outer side of the buffer shell 432 is subjected to force and indents inward, it can be buffered and supported again by the buffer rings 434. After the external force disappears, the outer side of the buffer shell 432 is restored by the elasticity of the buffer rings 434, which can further improve the buffering effect.

[0043] Specifically, the buffer mechanism 43 utilizes buffer sleeve one 431 and buffer sleeve two 433 to provide multi-level elastic support. Combined with the graded deformation of the buffer shell 432 and the buffer ring 434, it can quickly dissipate impact energy, making the buffering and energy absorption effect of the elastic mechanism 4 more uniform and reliable.

[0044] An impact-resistant reinforced cable protection pipe, as described in the reference Figure 3 and Figure 4 The buffer shell 432 includes a front layer 4321 and a rear shell 4322. The ends of the first buffer sleeve 431 and the second buffer sleeve 433 away from the fixed sleeve block 41 are connected to the rear shell 4322 to ensure stable force transmission. The end of the rear shell 4322 away from the first buffer sleeve 431 is connected to the front layer 4321. The rear shell 4322 is made of rigid material, and the front layer 4321 is made of elastic material. The use of rigid material for the rear shell 4322 can ensure support rigidity, while the use of elastic material for the front layer 4321 can achieve flexible buffering. This combination of rigidity and flexibility in the buffer shell 432 can effectively attenuate impact force and enhance the protection effect on the cable 2.

[0045] Specifically, the impact force can first be absorbed and diffused by the front layer 4321, and then transferred to the rear shell 4322, buffer sleeve 1 431 and buffer sleeve 2 433 by the buffer ring 434, so as to achieve layered buffering and effectively improve the impact resistance and energy absorption layer of the buffer shell 432.

[0046] An impact-resistant reinforced cable protection pipe, as described in the reference Figure 6 and Figure 7 The inner side of the outer jacket 7 has at least two sets of reinforcing ribs 71 arranged in a circular shape, and the inner side of the outer jacket 7 has at least two sets of reinforcing rings 72 arranged axially. The reinforcing ribs 71 and the reinforcing rings 72 cooperate to form a cage-like structure, which effectively improves the protection effect on the cable. The outer side of the outer jacket 7 has an outer texture 73.

[0047] Specifically, the combination of reinforcing rib 71 and reinforcing ring 72 can significantly improve the radial compressive strength and axial bending strength of the outer jacket 7. The outer texture 73 on the outside of the outer jacket 7 can increase surface friction and gripping force, prevent displacement after laying, and improve the protection and installation stability of the outer jacket 7.

[0048] This application provides an impact-resistant reinforced cable protection pipe. Through the multi-layer protective structure on the outside of the integrated sleeve 1, combined with the multi-level buffer components in the elastic mechanism 4, it achieves layered impact dissipation, avoids stress concentration, and can withstand repeated impacts, significantly improving the impact resistance of the pipe. The honeycomb energy-absorbing sleeve 6 and the soft and hard buffer shell 432 work together to absorb impacts with a rigid-flexible coupling structure, balancing lightweight and structural strength with the same wall thickness. The reinforcing ribs 71 and reinforcing rings 72 on the inside of the outer sleeve 7 form a cage-like skeleton to improve compressive and bending resistance. The outer texture 73 on the outside of the outer sleeve 7 can increase soil friction and prevent pipe displacement after laying. The multiple sets of support rings 3 with hollowed-out grooves on the outside of the integrated sleeve 1 can evenly distribute the load, reduce the weight, optimize the force transmission path, prevent local cracking, and improve the overall deformation resistance of the pipe.
