[0002] Cable protection conduit is more than just a simple casing; it is a metal or non-metallic tubing with multiple functions, including high strength, corrosion resistance, and UV resistance. It plays a vital role in modern communications and power systems. With the advancement of technology and the improvement of infrastructure, cable laying is becoming more and more widespread, involving a growing number of fields, including communications, transportation, and power supply. To ensure the stable operation of cables in complex environmental conditions and prevent damage from various potential threats, cable protection conduits can protect cables from physical damage such as extrusion, abrasion, and impact. At the same time, cable protection conduits can effectively isolate magnetic field interference generated by power lines, ensuring stable transmission of communication cable signals. However, some existing cable protection conduits have problems during installation and use. When installing multiple cables, the arrangement and installation of these conduits are often cumbersome and complex, causing certain difficulties for construction workers. Furthermore, due to poor fixing, cable protection conduits are prone to slipping, resulting in unstable installation alignment and even bending, further affecting the stable operation of the cables.

[0028] See also Figure 1-4 , the utility model provides a technical solution:

[0029] A UV-resistant CPVC cable protection tube, comprising a connecting bottom plate 1 and an iron fixed frame seat 3, three iron fixed frame seats 3 are provided, the front lower portion and the rear lower portion of the three iron fixed frame seats 3 are fixedly connected to a limited length sliding frame 6, the upper middle portion of the three iron fixed frame seats 3 are each provided with a U-shaped groove 4, the inner middle portion of the left wall and the inner middle portion of the right wall of the three iron fixed frame seats 3 are each provided with an H-shaped slot 5 with an upper end passing through, and the left iron fixed frame seat 3 is respectively provided with two H An H-shaped magnetic suction block 8 is movably inserted into the slot 5, and a card plate 7 is fixedly connected between the two H-shaped magnetic suction blocks 8. An arc groove 10 is opened in the middle of the lower end of the card plate 7. A protective tube assembly 9 is arranged in the card plate 7, and the protective tube assembly 9 is located in the arc groove 10. The upper front end and the upper rear end of the connecting base plate 1 are both provided with a limiting slide groove 2 that passes through the left end. The connecting base plate 1 is slidably connected to the three iron fixed frame seats 3 through two limiting slide grooves 2 and two limiting long slide frames 6.

[0030] In this embodiment, the protective tube assembly 9 includes a CPVC tube body 91. The upper portion of the outer surface of the CPVC tube body 91 is fixedly connected to the clamping plate 7. The inner wall of the CPVC tube body 91 is fixedly connected to an insulating layer 92. The inner wall of the insulating layer 92 is fixedly connected to a metal wire reinforcement layer 93. The inner wall of the metal wire reinforcement layer 93 is fixedly connected to a corrosion-resistant layer 94. The upper portion and the lower portion of the outer surface of the CPVC tube body 91 are respectively located in the arc groove 10 and the U-shaped groove 4.

[0031] Through the above solution: the CPVC pipe body 91 serves as the main body of the protective tube assembly 9, providing an external protective structure and protection against ultraviolet radiation. The insulating layer 92 can isolate the current, preventing current leakage or unnecessary electrical conduction with the outside world, and ensuring electrical safety. The metal wire reinforcement layer 93 enhances the overall strength and toughness of the pipe body, enabling it to better withstand external forces and prevent easy damage and deformation during use. The innermost corrosion-resistant layer 94 can effectively resist erosion of the interior of the pipe body by various corrosive substances. By positioning the upper outer surface of the CPVC pipe body 91 within the arcuate groove 10 and the lower outer surface within the U-shaped groove 4, the pipe body can be limited and fixed to ensure its stable position. On the other hand, the arcuate groove 10 and the U-shaped groove 4 also provide specific installation space and support for the pipe body, ensuring that the protective tube assembly 9 can perform its function in the corresponding structure, effectively protecting the cables inserted inside and enhancing its strength, thereby greatly extending the service life of the pipe body.

[0032] In this embodiment, the two H-shaped magnetic suction blocks 8 are respectively adapted to the sizes of the two H-shaped slots 5, and the clamping plate 7 is magnetically adsorbed and connected to the iron fixed frame seat 3 through the two H-shaped magnetic suction blocks 8 and the two H-shaped slots 5. The two limiting long sliding frames 6 are respectively adapted to the sizes of the two limiting slide grooves 2, and the lower end surface of the iron fixed frame seat 3 is tightly attached to the upper end surface of the connecting base plate 1 but not fixed.

[0033] Through the above scheme: first, the upper outer surface of the CPVC tube body 91 is fixed to the card plate 7, and the upper outer edge thereof is located in the arc groove 10, and then the CPVC tube body 91 is clamped in the U-shaped groove 4 to achieve preliminary positioning and limiting. Next, the H-shaped magnetic suction block 8 on the card plate 7 is aligned with the H-shaped slot 5 on the iron fixed frame seat 3. Due to the size adaptation and magnetic adsorption force, the card plate 7 can be quickly and firmly connected to the iron fixed frame seat 3, thereby achieving the fixation of the protective tube assembly 9. At the same time, the adaptation of the limiting long sliding frame 6 and the limiting sliding groove 2 ensures the accurate installation and stable sliding of the card plate 7 and the protective tube assembly 9 connected thereto in a certain direction, which facilitates the sequential installation of multiple protective tube assemblies 9. Because the iron fixed frame seat 3 is close to the connecting base plate 1 but not fixed, it is convenient for personnel to quickly and accurately complete the installation of multiple protective tubes, thereby improving the installation efficiency, and the installation and disassembly are relatively convenient, which is beneficial to the subsequent cable maintenance and replacement work.

[0034] It should be noted that the present invention is a CPVC cable protection tube that is resistant to UV aging. During use, the cable is first inserted into the adapted CPVC tube body 91. The CPVC tube body 91 serves as the main protective structure, providing physical protection for the cable to prevent external mechanical damage, wear, and UV irradiation aging. The insulating layer 92 is provided to isolate the current, thereby preventing the cable from leaking and contacting external conductive objects, thereby ensuring electrical safety. The metal wire reinforcement layer 93 enhances the overall strength of the tube body, making it less likely to deform and be damaged when the tube body is subjected to the cable's own gravity, external pressure, etc., thereby ensuring continuous and effective protection of the cable. The corrosion-resistant layer 94 can resist various corrosive substances in the environment, extend the service life of the tube body, and ensure that the cable can work stably under various environmental conditions. When installing multiple cables When installing, the three iron fixed frame seats 3 can be slid along the limiting slide groove 2 on the connecting bottom plate 1 through the limiting long sliding frames 6 at the front and rear ends thereof. The position of each iron fixed frame seat 3 can be determined as needed. At the same time, the H-shaped magnetic suction block 8 on the card plate 7 is aligned with the H-shaped slot 5 on the iron fixed frame seat 3, and the card plate 7 and the iron fixed frame seat 3 are quickly connected by magnetic adsorption force. At this time, the upper part of the outer surface of the CPVC pipe body 91 is located in the arc groove 10, and the lower part is located in the U-shaped groove 4, which can achieve preliminary fixation of the cable in the pipe. For subsequent cables, the above steps can be repeated and installed in different protective tube assemblies 9 in turn. During the installation process, due to the size adaptability and convenient connection method between the various structures, the installation of multiple cables can be carried out efficiently and orderly, and it is also convenient for the subsequent adjustment or maintenance of individual cables.
