Description

Technical Field

[0001] This utility model belongs to the field of cable protection technology, and specifically relates to a reinforcement structure for CPVC cable protection pipe. Background Technology

[0002] In the field of power and communication engineering, cable protection pipes are key facilities to ensure the safe operation of cables. In particular, CPVC (chlorinated polyvinyl chloride) protection pipes are widely used in sections where communication cables and power lines cross due to their excellent insulation, corrosion resistance and mechanical strength. They can effectively prevent line faults caused by external damage or short circuit accidents.

[0003] In existing technologies, such as the CPVC power cable protection pipe disclosed in Chinese Patent No. CN214429156U, the combination design of fixing posts, outward-facing panels, and fixing cones enhances the fixing effect of the bottom of the protection pipe in the soil, solving the problem of protection pipe breakage caused by bottom loosening or partial collapse. However, this device still has obvious limitations: First, the protection pipe and the fixing mechanism adopt an integrated or tightly fitted installation method. When it is necessary to perform regular maintenance or replacement of the cable or protection pipe, it is difficult to quickly remove the protection pipe from the fixing mechanism, resulting in cumbersome maintenance operations and significantly increasing maintenance time and labor costs. Second, the complex fixing structure requires the use of professional tools for the installation and removal of the protection pipe, and may even cause secondary damage due to mechanical stress during the disassembly process, affecting the reliability of the cable system. These problems restrict the maintenance efficiency and ease of use of cable protection pipes in actual engineering. It can be seen that the existing technology has certain defects and shortcomings, so it is necessary to improve its design. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a reinforcement structure for CPVC cable protection pipes to solve the problem of inconvenient maintenance during the application of existing technologies.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A reinforcement structure for a CPVC cable protection pipe includes a mounting plate, a reinforcement mechanism fixedly mounted at the top center of the mounting plate, and a heat-resistant protection pipe mounted on the top of the mounting plate through the reinforcement mechanism.

[0007] The heat-resistant protective tube includes a CPVC outer tube, which is clamped and installed inside the reinforcement mechanism. A heat-resistant layer is fixedly connected inside the CPVC outer tube, and a heat-resistant filler layer is filled inside the heat-resistant filler layer. The cable body is fixedly connected inside the heat-resistant filler layer.

[0008] As a preferred technical solution, the heat-resistant layer is configured as a heat-resistant aerogel layer, and the heat-resistant filling layer is configured as a ceramicized silicone rubber filling layer.

[0009] As a preferred technical solution, the reinforcement mechanism includes a rail frame, which is fixedly installed at the top center of the mounting plate. Two lead screws are rotatably connected inside the rail frame, and the inner ends of the two lead screws are fixedly connected to each other. The two ends of the two lead screws have opposite thread directions. A slider is threaded to both ends of the lead screws. The slider is slidably connected inside the rail frame. A base plate is fixedly connected to the top of the slider. A clamping frame is fixedly installed on the top of the base plate. An adjustment component is provided through the rail frame at the end of the lead screw.

[0010] As a preferred technical solution, the clamping frame includes connecting arms, which are linearly arranged at equal intervals and fixedly connected to the top of the substrate. A clamping seat is fixedly connected to the top of the connecting arms. A clamping groove is provided on the inner side of the clamping seat. The overall cross-sectional shape of the clamping groove is V-shaped. The outer corners of the clamping seat, connecting arms, rail frame and mounting plate are all rounded.

[0011] As a preferred technical solution, the adjustment component includes a mounting plate, which is fixedly installed on the outer end of the rail frame. An adjustment handle is rotatably connected to the outer side of the mounting plate. A locking screw is threaded to the upper end of the outer surface of the adjustment handle. Limiting holes are provided on the outer side of the mounting plate in a ring at equal intervals. The end of the locking screw is inserted into the limit hole. The locking screw is configured as a hand-tightening screw.

[0012] As a preferred technical solution, the mounting plate is fixedly installed with support rails on both sides of the top, and the support rails are slidably connected with support blocks inside, and the top of the support blocks is fixedly connected to the top of the base plate.

[0013] As a preferred technical solution, mounting holes are provided at the four corners of the top of the mounting plate, and the mounting holes on the mounting plate are countersunk holes.

[0014] In summary, the present invention has the following main advantages:

[0015] First, this CPVC cable protection pipe adopts a synergistic design of an aerogel heat-resistant layer and a ceramicized silicone rubber filler layer, which significantly enhances its heat resistance. The aerogel, with its nano-porous structure and extremely low thermal conductivity, can effectively block heat conduction and withstand temperatures exceeding 600℃, effectively delaying the aging of the cable insulation layer. The ceramicized silicone rubber filler layer is flexible at room temperature and can tightly fill the gaps in the cable, buffering external mechanical impacts; at high temperatures, it rapidly ceramicizes to form a heat insulation layer, which, together with the aerogel, constitutes a double heat-resistant barrier, blocking heat and flames. The combination of the two not only improves the high-temperature resistance of the protection pipe but also enhances its structural stability, making it suitable for complex environments such as high temperature, fire, and vibration, and extending the service life of the cable.

[0016] Secondly, this device adopts a reinforcement mechanism with mechanical transmission design, which can ensure the stable installation of the heat-resistant protective tube. The protective tube is placed in the clamping groove, and the adjustment handle is rotated to drive the lead screw to rotate. The reverse threads at both ends of the lead screw drive the slider to slide symmetrically along the guide rail, so that the base plate moves closer to the clamping seat. The inclined inner wall of the V-shaped clamping groove can adaptively fit the outer surface of the protective tube to form a uniform clamping force and prevent it from shifting under external force. The standard mounting holes of the bottom mounting plate are matched with bolts, which can be quickly fixed to various carriers. After installation, the locking screw is inserted into the limit hole to fix the lead screw, further enhancing the overall stability.

[0017] Third, during the application of this device, the reinforcement mechanism makes its operation simple and efficient during maintenance. During use, simply rotate the locking screw in the reverse direction to disengage it from the limit hole, release the screw constraint, and then rotate the adjusting handle to move the screw-driven slider outward, causing the clamping seat to separate, and the heat-resistant protective tube can be easily removed. The whole process does not require special tools, and the operation process is simple and clear, greatly shortening the maintenance time. This design not only ensures the stability of the protective tube in daily use, but also significantly improves the convenience of equipment maintenance and reduces operation and maintenance costs and manpower consumption.

[0024] Example

[0025] refer to Figures 1 to 5 The reinforcement structure of a CPVC cable protection pipe in this embodiment includes a mounting plate 1, a reinforcement mechanism 2 fixedly installed in the middle of the top of the mounting plate 1, and a heat-resistant protection pipe 3 installed on the top of the mounting plate 1 through the reinforcement mechanism 2.

[0026] The heat-resistant protective tube 3 includes a CPVC outer tube 31, which is clamped and installed inside the reinforcement mechanism 2. A heat-resistant layer 32 is fixedly connected inside the CPVC outer tube 31, and a heat-resistant filler layer 33 is filled inside the heat-resistant filler layer 33. The cable body 34 is fixedly connected inside the heat-resistant filler layer 33. During the use of this CPVC cable protection tube reinforcement structure, the mounting plate 1 is first fixed to the ground, wall, or other carrier using bolts through the standard mounting holes 4 on the top of the mounting plate 1 to provide stable support for the whole structure. Then, the heat-resistant protective tube 3 is placed between the clamping slots 253 of the reinforcement mechanism 2. The adjusting handle 262 of the reinforcement mechanism 2 is rotated, which drives the lead screw 22 to rotate. The reverse threads at both ends of the lead screw 22 are utilized. The two sliders 23 are driven to slide symmetrically along the guide rail, thereby moving the base plate 24 and connecting arm 251 on the top of the slider 23, so that the clamping seats 252 are brought closer to each other. The V-shaped clamping groove on the inner side of the clamping seat 252 can adaptively fit the circular outer surface of the CPVC outer tube 31 by means of the inclined inner wall, forming a uniform and firm clamping force, and stably fixing the heat-resistant protection tube 3 in the reinforcement mechanism 2. Inside the heat-resistant protection tube 3, the CPVC outer tube 31 provides basic protection, the heat-resistant layer 32 of aerogel material effectively blocks the conduction of external heat, and the ceramicized silicone rubber filling layer buffers vibration and impact at room temperature and quickly ceramicizes to form a heat insulation layer at high temperature. The three work together to protect the internal cable body 34 and ensure its safe and stable operation in complex environments.

[0027] refer to Figure 1 and Figure 4The heat-resistant layer 32 is a heat-resistant aerogel layer, and the heat-resistant filling layer 33 is a ceramicized silicone rubber filling layer. This CPVC cable protection pipe is first installed securely on the ground, wall, or other carriers using bolts through the mounting holes 4 on the mounting plate 1, providing a solid foundation for the whole. After the heat-resistant protection pipe 3 is placed in the clamping groove 253 of the reinforcement mechanism 2, the adjusting handle 262 is turned to drive the lead screw 22 to rotate. Due to the reverse threads at both ends of the lead screw 22, the slider 23 slides symmetrically along the guide rail, driving the base plate 24, connecting arm 251, and clamping seat 252 to move. The V-shaped clamping groove adaptively fits the CPVC outer pipe 31, forming a firm clamp. The heat-resistant protective tube 3 inside and the CPVC outer tube 31 resist external mechanical damage; the heat-resistant aerogel layer, with its nano-porous structure and low thermal conductivity, effectively blocks external heat, withstands temperatures exceeding 600℃, and delays cable aging; the ceramicized silicone rubber filling layer is flexible at room temperature, filling cable gaps and buffering vibration and impact, and rapidly ceramicizes at high temperatures to build a hard heat insulation layer. The three work together to protect the cable body 34 in all aspects, ensuring its stable operation under complex conditions such as high temperature and vibration.

[0028] refer to Figures 1-3The reinforcement mechanism 2 includes a rail frame 21, which is fixedly installed at the top center of the mounting plate 1. Two lead screws 22 are rotatably connected inside the rail frame 21, with their inner ends fixedly connected to each other. The two ends of the lead screws 22 have opposite thread directions. Slider blocks 23 are threaded to both ends of the lead screws 22, and the sliders 23 are slidably connected inside the rail frame 21. A base plate 24 is fixedly connected to the top of the sliders 23, and a clamping frame 25 is fixedly installed on the top of the base plate 24. An adjustment assembly 26 is provided at the end of the lead screws 22, penetrating the rail frame 21. The clamping frame 25 includes connecting arms 251, which are linearly arranged at equal intervals and fixedly connected to the top of the base plate 24. The top of the connecting arms 251... A clamping seat 252 is fixedly connected to the part. A clamping groove 253 is provided on the inner side of the clamping seat 252. The overall cross-sectional shape of the clamping groove 253 is V-shaped. The outer corners of the clamping seat 252, connecting arm 251, rail frame 21 and mounting plate 1 are all rounded. During the use of this device, when installing, the lead screw 22 can be rotated by adjusting component 26. Since the inner ends of the two lead screws 22 are fixedly connected and the threads at both ends are opposite, rotation can drive the two sliders 23 on the same lead screw 22 to slide in opposite directions along the inside of the rail frame 21. At the same time, it drives the two base plates 24 on both sides to move synchronously towards or away from each other. The connecting arm 251 and the clamping seat 252 at the top of the base plate 24 move with the base plate 24. The inclined inner wall of the U-shaped clamping groove 253 generates guiding force, which can adaptively fit the circular outer surface of the heat-resistant protective tube 3. The uniform clamping force is formed by symmetrical extrusion, ensuring that the protective tube is firmly fixed. The rounded corner design of components such as the rail frame 21 and the base plate 24 can reduce stress concentration and avoid sharp edges from scratching the operator or abrading the surface of the protective tube. At the same time, it can improve the impact resistance of the overall structure. The entire clamping process is precisely controlled by mechanical transmission, which can not only ensure installation stability, but also quickly release the clamp by rotating the screw 22 in the opposite direction, meeting the needs of convenient disassembly and assembly.

[0029] refer to Figures 1-2 and Figure 5The adjusting assembly 26 includes a mounting plate 261, which is fixedly mounted on the outer end of the rail frame 21. An adjusting handle 262 is rotatably connected to the outer side of the mounting plate 261. A locking screw 263 is threadedly connected to the upper end of the outer surface of the adjusting handle 262. Limiting holes 264 are evenly spaced and arranged in a ring on the outer side of the mounting plate 261. The end of the locking screw 263 is inserted into the limiting hole 264. The locking screw 263 is a hand-tightening screw. Supporting guide rails 265 are fixedly mounted on both sides of the top of the mounting plate 1. Supporting blocks 2 are slidably connected inside the supporting guide rails 265. 66. The top of the support block 266 is fixedly connected to the top of the base plate 24. Mounting holes 4 are provided at the four corners of the top of the mounting plate 1. The mounting holes 4 on the mounting plate 1 are countersunk holes. During the use of this device, it works in coordination with the support structure through the adjustment component 26 to achieve stable clamping and convenient adjustment of the heat-resistant protective tube 3. During installation, by turning the adjustment handle 262 by hand, the lead screw 22 in the mounting plate 261 is rotated. Utilizing the reverse thread characteristics at both ends of the lead screw 22, the slider 23 is driven to slide along the rail frame 21, thereby moving the base plate 24 and the clamping frame 25, so that V The U-shaped clamping groove 253 is fitted into the heat-resistant protective tube 3 to complete the fixation. After fixation, the hand-tightening locking screw 263 is screwed into the limiting hole 264 of the mounting plate 261 to limit the rotation of the adjusting handle 262, prevent the screw 22 from loosening due to external force, and ensure clamping stability. The sliding cooperation between the support guide rail 265 and the support block 266 provides guidance and auxiliary support for the movement of the base plate 24 and avoids the base plate 24 from shifting. The countersunk holes at the four corners of the mounting plate 1 can be used with countersunk bolts to firmly install the reinforcement mechanism 2 on the ground, wall and other carriers. The screw head is countersunk into the hole to make the mounting surface flat, enhance the overall structural strength, and facilitate disassembly and maintenance. The clamping can be loosened and the protective tube can be quickly removed by simply reversing the operation of the locking screw 263 and the adjusting handle 262.

[0030] Operating principle and advantages: This CPVC cable protection pipe possesses strong heat resistance through the synergistic design of an aerogel heat-resistant layer 32 and a ceramicized silicone rubber filler layer. During application, the heat-resistant layer 32, made of aerogel, effectively blocks external heat conduction due to its nano-porous structure and extremely low thermal conductivity, withstanding temperatures above 600℃. This significantly reduces cable surface temperature and slows down insulation aging. Simultaneously, the heat-resistant filler layer 33, made of ceramicized silicone rubber, is a flexible rubber at room temperature, tightly filling the gap between the cable and the protection pipe, absorbing vibration and impact energy, and effectively buffering external mechanical damage. In high-temperature environments, this material rapidly ceramicizes to form a hard heat-insulating layer, working together with the aerogel to construct a double heat-resistant barrier, blocking heat transfer and flame spread. This combination not only significantly improves the high-temperature resistance of the protection pipe but also enhances structural stability, preventing deformation and wear caused by external forces. It is suitable for complex environments such as industrial high temperatures, fire hazards, and frequent vibrations, significantly extending cable service life.

[0031] During the application of this device, its reinforcement mechanism 2, through mechanical transmission design, can achieve stable clamping and convenient disassembly / removal of the heat-resistant protective tube 3. During use, the heat-resistant protective tube 3 can be placed between the two clamping slots 253. Manually rotating the adjusting handle 262 drives the lead screw 22 to rotate synchronously. Because the lead screw 22 has a reverse thread design at both ends, it can drive the two sliders 23 to slide symmetrically along the guide rail, thereby causing the base plate 24 on top of the sliders 23 to move towards each other. When the base plate 24 moves, it pushes the clamping seats 252 closer together through the connecting arm 251. The V-shaped clamping slots 253 inside the clamping seats 252 generate [something] due to the inclined inner wall. The guiding force can adaptively fit the outer surface of the circular heat-resistant protective tube 3 to form a tight and uniform clamping force, ensuring that the protective tube will not shift due to external shaking or vibration after installation. During the installation process, the mounting plate 1 at the bottom of the reinforcement mechanism 2 is equipped with standard mounting holes 4, which can be quickly fixed to the ground, wall or other support frame by bolts, providing a stable foundation support. After the heat-resistant protective tube 3 is clamped, the locking screw 263 is inserted into the corresponding limiting hole 264. The screw and the hole are used to fix the lead screw 22 axially, preventing it from rotating due to external force during use, and further enhancing the stability of the overall structure.

[0032] During the inspection and maintenance phase, the mechanism demonstrates exceptional convenience. Simply rotate the locking screw 263 in the reverse direction to disengage it from the limiting hole 264, releasing the constraint on the lead screw 22. Then, rotate the adjusting handle 262 to drive the lead screw 22 to move the slider 23 outward in the reverse direction, thereby causing the clamping seat 252 to separate to both sides. The heat-resistant protective tube 3 can be easily removed from the clamping groove 253. The entire disassembly and assembly process requires no complex tools, and the operation procedure is clear and efficient, significantly shortening the maintenance time. This ensures the stability of daily use and significantly improves the convenience of equipment maintenance.
