Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable laying technology, and in particular to a cable bundle and fireproof partition bracket for dense cables. Background Technology
[0002] In industrial production, high-rise buildings, data centers, and other scenarios, dense cable cabling systems are the core carriers of power transmission and signal communication. Traditional dense cable cabling often uses simple cable ties, ordinary metal brackets for support, or direct conduit laying, lacking systematic cable bundling and fireproof separation design, leading to many prominent problems. Regarding cabling order, when dense cables lack effective bundle constraints, they are prone to tangling, stacking, and compression. This not only increases the difficulty of construction and subsequent maintenance, leading to low troubleshooting efficiency, but also causes poor heat dissipation due to the messy cable arrangement. Prolonged high-temperature environments accelerate the aging of cable insulation layers, creating potential safety hazards. At the same time, disordered cabling occupies too much space and is difficult to adapt to the compact and orderly requirements of modern cabling scenarios. More importantly, fire safety is insufficient. Traditional supports are mostly made of ordinary metal and lack fire-resistant partitions. When a fire breaks out due to overload or short circuit in a single cable, flames and smoke can easily spread rapidly along the gaps between the cables, causing the fire to escalate, resulting in large-scale power outages and equipment damage, and even threatening the lives of people. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a cable bundle and fireproof partition bracket for dense cable routing. It solves the technical problems of traditional dense cable routing, which easily leads to cables stacking and tangling, making construction and maintenance difficult and causing poor heat dissipation, thus increasing the risk of fire. Furthermore, traditional brackets lack sufficient fire safety and cannot promptly block the spread of fire. This invention achieves the purpose of sorting and separating cables to avoid stacking and tangling, which leads to poor heat dissipation and fire, and can also block the spread of fire in the event of a fire.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a cable bundle and fireproof partition bracket for dense cables, including a bracket and a top cover covering it. Multiple fireproof partition plates are fixedly arrayed in the bracket to form multiple cable routing cavities. Fireproof brackets that block the spread of fire are fixedly connected in the cable routing cavities. Insertion blocks are slidably installed in the fireproof brackets. Slider blocks that slide in the sliding grooves on the inner wall of the fireproof brackets are fixedly connected to both sides of the insertion blocks. A liquid storage cavity for storing flame retardant is opened inside the insertion blocks. Liquid outlet holes are opened at the bottom of both side walls of the insertion blocks. Bismuth-based alloy blocks are adhered to the liquid outlet holes with strong adhesive.
[0005] A further improvement is that the fireproof bracket has a U-shaped structure, and the bottom of the plug block has a semi-circular groove that matches the U-shaped bracket.
[0006] A further improvement is that the fireproof bracket has a sliding hole extending into its groove, and the slider also has a sliding hole. A plug rod slides in the sliding hole, and a spring sleeved on the plug rod is installed in the cavity inside the sliding hole of the fireproof bracket.
[0007] A further improvement is that the bracket has insertion holes at all four corners of its top, and the bottom of the top cover has fixing rods that are compatible with the insertion holes at all four corners.
[0008] A further improvement is that a smoke sensor is installed on the top wall of the cover, and an alarm light electrically connected to the smoke sensor is installed on the top of the cover.
[0009] A further improvement is that the bracket and the top cover are both made of steel fireproof board material, the fireproof partition and the fireproof bracket are both made of flame-retardant resin material, and the surface of the above components is provided with a fireproof layer, which is made of fireproof felt material.
[0010] By employing the above technical solution, this utility model provides a cable bundle and fireproof partition bracket for dense cables, which has at least the following beneficial effects: 1. This utility model avoids the cables from stacking and tangling by placing them separately on fireproof brackets inside the cable routing cavity, thus achieving independent separation of the cables. Then, the sliders on both sides of the plug block are aligned with the grooves on the fireproof bracket and inserted. The semi-circular groove at the bottom of the plug block cooperates with the fireproof bracket to seal and fix the cable from the top and bottom sides. An independent fireproof space is formed between two adjacent fireproof brackets, thereby blocking the fire and preventing its spread.
[0011] 2. When a cable in one section of the space catches fire, the high temperature generated will melt the bismuth-based alloy block with a melting point of about 108°. At this time, the flame retardant stored in the liquid storage chamber inside the plug block will flow out through the liquid outlet hole, blocking the fire in that section of the space and thus preventing the fire from spreading.
[0012] 3. When a local cable catches fire, the smoke generated is captured by a smoke sensor in that space and sends an electrical signal to the alarm light. The alarm light then emits an audible and visual alarm to alert people that the cable is on fire, making it easier for people to pinpoint the fire source in time, extinguish it accurately, and prevent the fire from spreading.

[0016] 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.
[0017] Addressing the issues of traditional dense cable routing leading to cable tangling, difficult construction and maintenance, poor heat dissipation, and increased risk of fire, as well as the inadequacy of traditional fire-resistant supports in preventing the spread of fire, this embodiment provides a cable bundling and fire-resistant partitioning support for dense cables. This support effectively organizes and separates cables, preventing tangling and subsequent poor heat dissipation that could lead to fires. Furthermore, it can effectively block the spread of fire in the event of a fire. Please refer to... Figures 1-5 The cable bundle and fireproof partition bracket for dense cables includes a bracket 1 and a top cover 11 covering it. Multiple fireproof partition plates 2 are fixedly arranged in an array inside the bracket 1 to form multiple cable routing cavities 3. Fireproof brackets 4 are fixedly arranged inside the cable routing cavities 3 to block the spread of fire. Insertion blocks 5 are slidably arranged inside the fireproof brackets 4. Slider blocks 6 are fixedly arranged on both sides of the insertion blocks 5 and are slidably arranged in the sliding grooves on the inner wall of the fireproof brackets 4. A liquid storage cavity 7 for storing flame retardant is opened inside the insertion blocks 5. Liquid outlet holes 8 are opened at the bottom of both side walls of the insertion blocks 5. Bismuth-based alloy blocks 9 are adhered to the liquid outlet holes 8 with strong adhesive.
[0018] The fireproof bracket 4 has a U-shaped structure, and the bottom of the plug-in block 5 has a semi-circular groove that matches the U-shaped bracket. The cables are placed on the fireproof bracket 4 in the cable routing cavity 3 to avoid the cables from stacking and tangling, thus achieving independent separation of the cables. Then, the sliders 6 on both sides of the plug-in block 5 are aligned with the grooves on the fireproof bracket 4 and inserted. The semi-circular groove at the bottom of the plug-in block 5 cooperates with the fireproof bracket 4 to seal and fix the cables from the top and bottom. The cables are separated into multiple relatively independent spaces by two adjacent fireproof brackets 4. When the cable in one of the spaces catches fire, the high temperature generated melts the bismuth-based alloy block 9 with a melting point of about 108°. At this time, the flame retardant stored in the liquid storage cavity 7 in the plug-in block 5 flows out through the liquid outlet 8 to block the fire in that space, thereby preventing the fire from spreading.
[0019] To prevent the cable from lifting the connector block 5 and creating a gap at the connection point, which could lead to the spread of fire, the fireproof bracket 4 has a sliding hole 61 extending into its groove, and the slider 6 also has a sliding hole 61. A connector rod 62 slides inside the sliding hole 61, and a spring 63 is installed in the cavity inside the sliding hole 61 of the fireproof bracket 4 and fitted onto the connector rod 62. When the sliders 6 on both sides of the connector block 5 are inserted into the groove on the inner wall of the fireproof bracket 4, the connector rod 62 is pulled in advance, causing it to move backward along the sliding hole 61 and compressing the spring 63. When the connector block 5 is fully inserted into the fireproof bracket 4 and presses against the cable, the connector rod 62 is released, and the spring 63 returns to its original position under its own elasticity, thereby pushing the connector rod 62 into the sliding hole 61 on the slider 6, completing the fixation of the connector block 5, thus preventing a gap from appearing between the connector block 5 and the top of the cable, which could lead to the spread of fire to the adjacent fireproof section.
[0020] To prevent the top cover 11 from sliding on top of the bracket 1, causing local misalignment and thus spreading the fire, insertion holes are provided at the four corners of the top of the bracket 1, and fixing rods 111 that match the insertion holes are fixed at the four corners of the bottom of the top cover 11. By inserting the fixing rods 111 at the bottom of the top cover 11 into the insertion holes at the top of the bracket 1, the top cover 11 and the bracket 1 are fixed, thereby preventing the top cover 11 from sliding on top of the bracket 1, causing misalignment and thus spreading the fire.
[0021] To promptly alert people to cable fires, a smoke sensor 112 is installed on the top wall of the cover 11, and an alarm light 113 electrically connected to the smoke sensor 112 is installed on the top of the cover 11. When a local cable catches fire, the smoke generated is captured by the smoke sensor 112 in that space and sends an electrical signal to the alarm light 113. The alarm light 113 then emits an audible and visual alarm to alert people to the cable fire, making it easier for people to pinpoint the fire source in time, extinguish it accurately, and prevent the fire from spreading.
[0022] Specifically, the bracket 1 and the top cover 11 are both made of steel fireproof board material, the fireproof partition 2 and the fireproof bracket 4 are both made of flame-retardant resin material, and the surface of the above components is provided with a fireproof layer 21, which is made of fireproof felt material.
