Description

Technical Field

[0001] This application relates to the field of bundled tube technology, specifically a rodent-proof bundled tube. Background Technology

[0002] With the acceleration of urbanization, underground cables and communication lines are being laid more and more densely. However, the problem of rodents gnawing on cables has always been a major challenge for the power and telecommunications industries. Statistics show that cable faults caused by rodents account for more than 15% of all cable faults annually, causing huge economic losses and social impacts. Currently, the industry mainly uses physical isolation and chemical repellents to deal with the rodent problem, but these methods have limited effectiveness and are costly.

[0003] The main drawback of existing technologies is that they cannot balance protective effectiveness, cost, and ease of use. While metal sheaths offer good protection, they are expensive and difficult to install; chemical rodent repellents have a short shelf life and may pollute the environment; and rigid plastic sheaths are prone to aging and cracking, resulting in poor long-term protective performance. To address these issues, a rodent-proof bundled tube is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a rodent-proof cable bundle that effectively prevents rodents from gnawing and damaging cables without the need for chemical rodent repellents, and offers significant protection.

[0005] To achieve the above objectives, this application provides the following technical solution: a rodent-proof bundled tube, comprising a bundled tube assembly, a rodent-proof assembly, and an outer sheath assembly. The rodent-proof assembly is located between the bundled tube assembly and the outer sheath assembly. The rodent-proof assembly includes a rodent-proof inner layer fixedly connected to the outer surface of the bundled tube assembly. An annular aluminum honeycomb core is sleeved on the outside of the rodent-proof inner layer. Each honeycomb cell in the annular aluminum honeycomb core is embedded with a silicone damping ball. A rodent-proof outer layer is sleeved on the outside of the annular aluminum honeycomb core. Multiple spirally wound stainless steel wires are installed inside the rodent-proof outer layer. Uniformly distributed barbed protrusions are installed on the inner wall of the rodent-proof outer layer. The outer sheath assembly includes an outer sheath layer fixedly connected to the outer surface of the rodent-proof assembly.

[0006] Through the above-described solution, this rodent-proof bundled tube achieves layer-by-layer synergistic protection through the bundled tube assembly, rodent-proof assembly, and outer sheath assembly. This structure effectively reduces rodent-related failure rates without the need for chemical rodent repellents. It also integrates heat dissipation, wear resistance, and corrosion resistance, extending service life and significantly improving the safety and economy of underground cable systems. The outer sheath layer makes it difficult for rodents to bite through. Even if the outer sheath is bitten, the rodent-proof assembly can still provide protection. The inner rodent-proof layer uses ultra-high molecular weight polyethylene fiber mesh, which physically blocks rodent teeth penetration through the mesh openings. The annular aluminum honeycomb core combined with silicone damping balls disperses impact energy, improving compressive strength. The spirally wound stainless steel wire and the barbed protrusions inside the outer rodent-proof layer reduce rodent gnawing through mechanical interference. The barbed protrusions can scratch the rodent's oral mucosa, thus creating a conditioned reflex of avoidance and actively changing the rodent's gnawing behavior, making it more practical.

[0007] Furthermore, the bundle tube assembly includes a bundle tube body, and a thermally conductive layer is fixedly connected to the outer surface of the bundle tube body. The thermally conductive layer is a graphene thermally conductive film.

[0008] The above solution, through the setting of the heat-conducting layer and the limitation of the material of the heat-conducting layer, enables the heat-conducting layer to have an ultra-high thermal conductivity, which can quickly and evenly dissipate the heat generated during cable operation, reduce the internal temperature of the outer sheath layer, effectively extend the service life of the cable and improve transmission stability.

[0009] Furthermore, the inner side of the bundle tube body is provided with an inner lining layer, which is a polytetrafluoroethylene film.

[0010] The above solution, through the design of the inner lining layer and the limitation of its material, enables the inner lining layer to have an extremely low coefficient of friction and self-lubricating properties, which can reduce the resistance of threading. At the same time, it has corrosion resistance and insulation properties, which significantly improves construction efficiency and long-term safety.

[0011] Furthermore, the rodent-proof inner layer is made of ultra-high molecular weight polyethylene fiber mesh.

[0012] The above solution limits the material of the rodent-proof inner layer, giving it ultra-high strength and wear resistance. Its mesh can physically block rodent teeth from penetrating, while maintaining lightweight design, achieving a balance between high-efficiency protection and ease of construction.

[0013] Furthermore, the annular aluminum honeycomb core is located between the rodent-proof inner layer and the rodent-proof outer layer.

[0014] The above scheme uses an annular aluminum honeycomb core as an intermediate buffer layer. Its honeycomb structure efficiently disperses the biting impact force, and combined with the elastic energy absorption characteristics of the silicone damping ball, it improves the impact resistance of the rodent-proof component.

[0015] Furthermore, the outer sheath is made of high-density polyethylene.

[0016] The above solution, by limiting the material of the outer sheath, enables the outer sheath to have excellent mechanical strength and corrosion resistance, while also being lightweight. It can effectively resist external impact and chemical erosion, is easy to install, and is inexpensive.

[0017] Furthermore, a wear-resistant layer is fixedly connected to the outer surface of the outer sheath layer, and the wear-resistant layer is made of polyurethane material.

[0018] Through the above scheme, by setting the wear-resistant layer and limiting the wear-resistant layer material, the wear-resistant layer can have excellent impact resistance and wear resistance, effectively resist construction friction and mechanical damage, extend the service life of the outer sheath layer, and at the same time maintain flexibility for easy bending and laying.

[0019] Furthermore, an outer anti-corrosion layer is fixedly connected to the outer surface of the wear-resistant layer, and the outer anti-corrosion layer is a fluorocarbon coating.

[0020] The above solution, through the setting of the external anti-corrosion layer and the limitation of the external anti-corrosion layer material, enables the external anti-corrosion layer to have super weather resistance and chemical inertness, which can significantly extend the service life of the outer sheath layer and is suitable for harsh environments such as humidity and salt spray.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This rodent-proof bundled tube achieves layer-by-layer synergistic protection through bundled tube components, rodent-proof components, and outer sheath components. This structure effectively reduces rodent-related failure rates without the need for chemical rodent repellents. It also integrates heat dissipation, wear resistance, and corrosion resistance, extending service life and significantly improving the safety and economy of underground cable systems. The outer sheath layer makes it difficult for rodents to chew through. Even if the outer sheath is chewed through, the rodent-proof components can still prevent rodent penetration. The inner rodent-proof layer uses ultra-high molecular weight polyethylene fiber mesh, which physically blocks rodent teeth penetration through the mesh openings. The annular aluminum honeycomb core combined with silicone damping balls disperses impact energy, improving compressive strength. The spirally wound stainless steel wire and the barbed protrusions inside the outer rodent-proof layer reduce rodent gnawing through mechanical interference. The barbed protrusions can scratch the rodent's oral mucosa, thus creating a conditioned reflex to repel them and actively changing their gnawing behavior, making it more practical.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 2 and Figure 3 This embodiment of a rodent-proof bundled tube includes a bundled tube assembly 1, a rodent-proof assembly 2, and an outer sheath assembly 3. The rodent-proof assembly 2 is located between the bundled tube assembly 1 and the outer sheath assembly 3. The bundled tube assembly 1 includes a bundled tube body 101, and a heat-conducting layer 102 is fixedly connected to the outer surface of the bundled tube body 101. The heat-conducting layer 102 is a graphene heat-conducting film. By setting the heat-conducting layer 102 and limiting the material of the heat-conducting layer 102, the heat-conducting layer 102 can have an ultra-high thermal conductivity, which can quickly and evenly dissipate the heat generated by the cable during operation, so that the outer sheath layer... The internal temperature of 301 is reduced, which effectively extends the service life of the cable and improves the transmission stability. The inner side of the bundle tube body 101 is provided with an inner lining layer 103, which is a polytetrafluoroethylene film. By setting the inner lining layer 103 and limiting the material of the inner lining layer 103, the inner lining layer 103 has an extremely low coefficient of friction and self-lubrication, which can reduce the resistance of wire pulling. At the same time, it has corrosion resistance and insulation properties, which significantly improves construction efficiency and long-term use safety. By optimizing the composition of the bundle tube assembly 1, the actual use effect of the bundle tube assembly 1 can be improved.

[0032] Please see Figure 3 , Figure 4 and Figure 5The rodent-proof component 2 includes a rodent-proof inner layer 201 fixedly connected to the outer surface of the bundle tube assembly 1. The rodent-proof inner layer 201 is made of ultra-high molecular weight polyethylene fiber mesh, which limits the material of the rodent-proof inner layer 201, giving it ultra-high strength and wear resistance. Its mesh can physically block rodent teeth from penetrating, while maintaining lightweight, achieving a balance between high-efficiency protection and ease of construction. Rodents cannot embed their teeth in the mesh and continue gnawing, thus achieving the rodent-proof effect of the rodent-proof inner layer 201. The outer surface of the rodent-proof inner layer 201 is fitted with an annular aluminum honeycomb core 202. Each honeycomb unit in the annular aluminum honeycomb core 202 is embedded with a silicone damping ball 203. The outer surface of the annular aluminum honeycomb core 202 is fitted with a rodent-proof outer layer 204. The inner surface of the rodent-proof outer layer 204 is fitted with multiple spirally wound stainless steel wires 205. The inner wall of the rodent-proof outer layer 204 is fitted with... The component is equipped with evenly distributed barbed protrusions 206. The spirally wound stainless steel wire 205 causes the rodent's teeth to slide along the spiral direction when it bites in a ring, preventing sustained force. The barbed protrusions 206 further scratch the rodent's oral mucosa, creating a conditioned reflex of avoidance. The stainless steel wire 205 and the barbed protrusions 206 work together to dynamically disrupt the biting rhythm. Combined with the inner rodent-proof layer 201, this provides a double rodent-proof effect without the need for chemical rodent repellents, making it safer. The annular aluminum honeycomb core 202 is located between the inner rodent-proof layer 201 and the outer rodent-proof layer 204, serving as an intermediate buffer layer. Its honeycomb structure efficiently disperses the biting impact force, and combined with the elastic energy-absorbing properties of the silicone damping ball 203, it improves the impact resistance of the rodent-proof component 2.

[0033] Please see Figure 1 , Figure 2 and Figure 3 The outer sheath assembly 3 includes an outer sheath layer 301 fixedly connected to the outer surface of the rodent-proof assembly 2. The outer sheath layer 301 is made of high-density polyethylene. By limiting the material of the outer sheath layer 301, it has excellent mechanical strength and corrosion resistance, while also being lightweight. It can effectively resist external impact and chemical corrosion, is easy to install, and is inexpensive. A wear-resistant layer 302 is fixedly connected to the outer surface of the outer sheath layer 301. The wear-resistant layer 302 is made of polyurethane material. Through the setting of the wear-resistant layer 302 and the limitation of the material of the wear-resistant layer 302, the wear-resistant layer 302 is effectively protected. The design ensures that the wear-resistant layer 302 has excellent impact resistance and abrasion resistance, effectively resisting construction friction and mechanical damage, extending the service life of the outer sheath layer 301, while maintaining flexibility for easy bending and laying. The outer surface of the wear-resistant layer 302 is fixedly connected to the outer anti-corrosion layer 303, which is a fluorocarbon coating. Through the design of the outer anti-corrosion layer 303 and the limitation of its material, the outer anti-corrosion layer 303 has excellent weather resistance and chemical inertness, which can significantly extend the service life of the outer sheath layer 301 and is suitable for harsh environments such as humidity and salt spray.

[0034] It should be noted that the diameter of the mesh openings in the stainless steel wire 205 winding and the inner rodent-proof layer 201 is smaller than the width of a rodent's teeth. This prevents rodents from embedding their teeth into the mesh openings and continuing to gnaw, thus optimizing the rodent-proof effect.

[0035] In this embodiment, the rodent-proof bundled tube achieves layer-by-layer synergistic protection through the bundled tube assembly 1, the rodent-proof assembly 2, and the outer sheath assembly 3. This structure effectively reduces the rodent-related failure rate without the need for chemical rodent repellents. It also integrates heat dissipation, wear resistance, and corrosion resistance, extending its service life and significantly improving the safety and economy of underground cable systems. The outer sheath layer 301 makes it difficult for rodents to bite through. Even if the outer sheath layer 301 is bitten through, the rodent-proof assembly 2 can still provide rodent protection. The inner rodent-proof layer 201 uses ultra-high molecular weight polyethylene fiber mesh, which physically blocks rodent teeth penetration through the mesh openings. The annular aluminum honeycomb core 202, combined with silicone damping balls 203, disperses impact energy and improves compressive strength. The outer rodent-proof layer 204 has spirally wound stainless steel wire 205 and barbed protrusions 206 inside, which reduce rodent gnawing through mechanical interference. The barbed protrusions 206 can scratch the oral mucosa of rodents, thereby forming a conditioned reflex to repel them and actively changing their gnawing behavior patterns, making it more practical.

[0036] The working principle of the above embodiment is as follows: The rodent-proof bundle tube of this utility model achieves efficient protection through the synergistic effect of multi-layer composite structure and dynamic mechanical design. The outer sheath layer 301 of the outer sheath assembly 3 serves as the first line of defense, resisting the initial gnawing of rodents with its high mechanical strength. If the outer sheath layer 301 is partially bitten, the rodent-proof assembly 2 immediately activates secondary protection. The rodent-proof inner layer 201 uses ultra-high molecular weight polyethylene fiber mesh, which physically blocks rodent teeth from penetrating through its mesh. At the same time, the silicone damping ball 203 embedded in the annular aluminum honeycomb core 202 absorbs impact energy through elastic deformation. Combined with the honeycomb structure to disperse stress, the compressive strength is improved. The spirally wound stainless steel wire 205 and the barbed protrusions 206 inside the rodent-proof outer layer 204 further disrupt the rodent's gnawing rhythm. The protrusion 206 scratches the oral mucosa of rodents when they gnaw, triggering a conditioned reflex to repel them and reducing their gnawing behavior. At the same time, the heat-conducting layer 102 of the bundle tube assembly 1 quickly dissipates the heat generated by the cable through its high thermal conductivity, reducing the internal temperature and preventing the insulation layer from overheating and aging. The inner lining layer 103 uses a low coefficient of friction to reduce the resistance of threading and improve construction efficiency. The wear-resistant layer 302 of the outer sheath assembly 3 can resist mechanical damage, and the outer anti-corrosion layer 303 extends the service life of the outer sheath assembly 3 through its superior weather resistance and adapts to harsh environments such as humidity and salt spray. The components work together layer by layer to effectively reduce the failure rate of rodents without the need for chemical rodent repellents. At the same time, it integrates heat dissipation, wear resistance, and corrosion resistance, significantly improving the safety, economy, and service life of the underground cable system.
