Description

Technical Field

[0001] This utility model relates to the field of PVC pipe technology, specifically a high-strength PVC cable protection pipe to prevent pipe body rupture. Background Technology

[0002] PVC pipes (polyvinyl chloride pipes) are a type of plastic pipe material widely used in construction, agriculture, industry, and daily life. PVC cable protection pipes are cable protection pipes made primarily of PVC resin. They play an important role in cable laying, not only being usable in humid and saline-alkali areas but also able to withstand high voltages of over 30,000 volts. They possess excellent electrical insulation properties, ensuring reliable line operation. However, if the protection pipe lacks good torsional resistance, it will be difficult to return to its original shape after being twisted or deformed, affecting subsequent use and greatly reducing its performance.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application number CN202221904685.9, application date 2022-07-23) provides a high-strength CPVC cable protection pipe that can prevent the protective pipe from breaking. It includes a CPVC pipe body that can be disposed on the outer layer of the cable, with a cavity inside the CPVC pipe body; a composite layer disposed inside the cavity; an anti-torsion layer fixed to the outer wall of the composite layer; and an anti-torsion strip disposed inside the anti-torsion layer. The anti-torsion strip is spirally fixed inside the anti-torsion layer, and a wavy elastic strip is uniformly connected between adjacent spiral portions of the anti-torsion strip. The anti-torsion strip and the wavy elastic strip can improve the overall strength of the CPVC protection pipe, making it less prone to breakage and damage. When the CPVC protection pipe becomes twisted and deformed under pressure, the spiral anti-torsion strip can generate rotational force, facilitating the restoration of the twisted and deformed CPVC protection pipe to its original shape. Furthermore, the wavy elastic strip can limit the distance between adjacent spiral portions of the anti-torsion strip, reducing the occurrence of deformation and damage under pressure.

[0004] Cable protection pipes buried under urban roads experience significant vertical pressure when heavy trucks and other vehicles pass over them. Because the pipes are not strong enough to withstand this pressure, they often rupture. Furthermore, the aforementioned devices fail to improve the compressive strength of the pipes during use, leading to rupture under significant external forces. They also fail to distribute the pressure evenly, reducing the pipes' lifespan. Utility Model Content

[0005] The purpose of this utility model is to provide a high-strength PVC cable protection pipe that prevents pipe body rupture, so as to solve the problems mentioned in the background art, which are that the compressive strength of the protection pipe cannot be improved, resulting in the protection pipe rupture when the external force is large, and that the pressure cannot be evenly distributed, thus reducing the service life of the protection pipe.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength PVC cable protection pipe for preventing pipe rupture, comprising a cable protection pipe, wherein an isolation cover is fixedly connected to the surface of the cable protection pipe, and through holes are provided inside the isolation cover, and the through holes are evenly distributed inside the isolation cover; one end of a support frame is fixedly connected to the surface of the isolation cover, and a reinforcing protective cover is fixedly connected to the other end of the support frame, and the support frame is triangular in view; a circular hole is provided inside the reinforcing protective cover, and reinforcing ribs are fixedly connected to the surface of the reinforcing protective cover, and the reinforcing ribs are evenly distributed on the surface of the reinforcing protective cover.

[0007] The above structural design, through the setting of reinforcing ribs and support frames, improves the protection of the cable protection pipe. When the cable protection pipe is subjected to external pressure, the reinforcing ribs can disperse the pressure and prevent the pressure from concentrating at a certain point or in a certain area, thereby enhancing the compressive strength of the entire protection structure.

[0008] Preferably, the surface of the cable protection pipe is bonded with a wear-resistant layer, and the wear-resistant layer is made of smooth PVC material.

[0009] The above structural design, through the use of a smooth PVC wear-resistant layer, can effectively reduce the coefficient of friction, reduce scratches and wear on the inner wall of the cable protection pipe caused by friction, protect the cable protection pipe body from excessive wear, and maintain its structural integrity and performance stability.

[0010] Preferably, a reinforcing layer is bonded to the surface of the wear-resistant layer, and the reinforcing layer is made of carbon fiber.

[0011] The above structural design, by setting a reinforcing layer made of carbon fiber, can effectively improve the overall tensile strength of the cable protection pipe. The reinforcing layer can bear most of the tensile stress, preventing the cable protection pipe from cracking or deforming due to tension, and ensuring that the pipe can maintain its structural integrity under various working conditions.

[0012] Preferably, a buffer layer is bonded to the surface of the reinforcing layer, and the buffer layer is made of PVC elastic material.

[0013] The above structural design, by setting a buffer layer of PVC elastic material, greatly reduces the impact force transmitted to the reinforcing layer and the internal tube, thereby reducing the risk of tube rupture due to impact and preventing cracks or damage to the tube.

[0014] Preferably, an electromagnetic shielding layer is bonded to the surface of the buffer layer, and the electromagnetic shielding layer is made of aluminum foil.

[0015] The above structural design, by setting an electromagnetic shielding layer made of aluminum foil, significantly reduces the impact of external electromagnetic interference on cable signals, ensuring that the cable can transmit signals stably and accurately.

[0016] Preferably, a heat insulation layer is bonded to the surface of the electromagnetic shielding layer, and the heat insulation layer is made of ceramic fiber.

[0017] The above structural design, by setting a ceramic fiber insulation layer, helps to maintain the stability of the cable's operating temperature, ensuring that the cable can transmit power or signals stably and reliably in various environments, and reducing signal interference or power transmission failures caused by temperature fluctuations.

[0018] Preferably, a water-blocking layer is bonded to the surface of the heat insulation layer, and the water-blocking layer is made of water-absorbing and swelling rubber material.

[0019] The above structural design, by setting a water-blocking layer made of water-absorbing and expanding rubber material, can effectively prevent water from penetrating into the pipe when there is water accumulation or a humid environment around the cable protection pipe, protect the cable from water damage, prevent the cable insulation layer from being damaged by moisture, and ensure the stable electrical performance of the cable.

[0020] Compared with the prior art, the beneficial effects of this utility model are: the high-strength PVC cable protection pipe that prevents pipe body breakage adopts a novel structural design, the specific details of which are as follows:

[0021] (1) The high-strength PVC cable protection pipe that prevents pipe body rupture improves the protection of the cable protection pipe through the setting of reinforcing ribs and support frame. When the cable protection pipe is subjected to external pressure, the reinforcing ribs can disperse the pressure and avoid pressure concentration, thereby enhancing the pressure resistance of the entire protection structure.

[0022] Furthermore, the wear-resistant layer of smooth PVC material can effectively reduce the coefficient of friction, thereby reducing scratches and wear on the inner wall of the cable protection pipe caused by friction.

[0023] (2) The high-strength PVC cable protection pipe that prevents pipe body rupture can effectively improve the overall tensile strength of the cable protection pipe through the reinforcement layer of carbon fiber material, prevent the cable protection pipe from rupturing or deforming due to tension, and ensure that the pipe can maintain structural integrity under various working conditions.

[0024] Furthermore, the electromagnetic shielding layer significantly reduces the impact of external electromagnetic interference on cable signals, ensuring that the cable can transmit signals stably and accurately.

[0025] (3) The high-strength PVC cable protection pipe that prevents pipe body rupture greatly reduces the impact force transmitted to the reinforcing layer and the inner pipe body through the buffer layer of PVC elastic material, thereby reducing the risk of pipe body rupture due to impact and preventing cracks or damage to the pipe body.

[0032] 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.

[0033] Example 1: By incorporating the cable isolation cover 2, reinforcing ribs 7, and reinforced protective cover 5, the protection of internal cables is improved, such as... Figures 1-3 As shown: It includes a cable protection pipe 1 and a cable isolation cover 2. The isolation cover 2 has through holes 3 inside, and the through holes 3 are evenly distributed inside the isolation cover 2. One end of the support frame 4 is fixedly connected to the surface of the isolation cover 2, and the other end of the support frame 4 is fixedly connected to a reinforcing protective cover 5. The support frame 4 is triangular in view. The reinforcing protective cover 5 has round holes 6 inside, and reinforcing ribs 7 are fixedly connected to the surface of the reinforcing protective cover 5. The reinforcing ribs 7 are evenly distributed on the surface of the reinforcing protective cover 5.

[0034] Workers guide one end of the cable into the cable protection pipe 1, allowing the cable to pass smoothly through the pipe. Simultaneously, they move the cable protection pipe 1, now with the cable inserted, to the designated location and accurately position it according to design requirements. The reinforcing ribs 7 and support frames 4 enhance the protection of the cable protection pipe 1. When the cable protection pipe 1 is subjected to external pressure, the reinforcing ribs 7 can disperse the pressure, preventing it from concentrating at a single point or in a specific area, thereby enhancing the overall compressive strength of the protection structure.

[0035] Example 2: In this example, unlike Example 1, the wear-resistant layer 8, buffer layer 10, and reinforcing layer 9 are used to extend the service life of the device. Figure 4 As shown: A wear-resistant layer 8 is bonded to the surface of the cable protection pipe 1, and the wear-resistant layer 8 is made of smooth PVC material. A reinforcing layer 9 is bonded to the surface of the wear-resistant layer 8, and the reinforcing layer 9 is made of carbon fiber material. A buffer layer 10 is bonded to the surface of the reinforcing layer 9, and the buffer layer 10 is made of elastic PVC material. An electromagnetic shielding layer 11 is bonded to the surface of the buffer layer 10, and the electromagnetic shielding layer 11 is made of aluminum foil material.

[0036] The wear-resistant layer 8 made of smooth PVC material effectively reduces the coefficient of friction, thereby reducing scratches and wear on the inner wall of the cable protection pipe 1 caused by friction. This protects the cable protection pipe 1 from excessive wear and maintains its structural integrity and performance stability. At the same time, the reinforcing layer 9 made of carbon fiber material effectively improves the overall tensile strength of the cable protection pipe 1, preventing it from cracking or deforming due to tension. This ensures that the pipe maintains its structural integrity under various working conditions. The buffer layer 10 made of elastic PVC material greatly reduces the impact force transmitted to the reinforcing layer 9 and the inner pipe body, thereby reducing the risk of pipe rupture due to impact and preventing cracks or damage to the pipe body.

[0037] In Example 3, unlike Example 2, the electrical performance of the internal cable is ensured by using a heat insulation layer 12, a water-blocking layer 13, and an electromagnetic shielding layer 11. Figure 5 As shown: A heat insulation layer 12 is bonded to the surface of the electromagnetic shielding layer 11, and the heat insulation layer 12 is made of ceramic fiber. A water-blocking layer 13 is bonded to the surface of the heat insulation layer 12, and the water-blocking layer 13 is made of absorbent rubber.

[0038] By setting a ceramic fiber insulation layer 12, the ceramic fiber insulation layer 12 helps to maintain the stability of the cable's operating temperature, ensuring that the cable can transmit power or signals stably and reliably in various environments, reducing signal interference or power transmission failures caused by temperature fluctuations. At the same time, the water-blocking layer 13, which absorbs water and expands rubber, can effectively prevent water from penetrating into the pipe when there is water accumulation or a humid environment around the cable protection pipe 1, protecting the cable from water damage, preventing the cable insulation layer from being damaged by moisture, and ensuring the stability of the cable's electrical performance.

[0039] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
