Description

Technical Field

[0001] This utility model relates to the field of cable trays, and more specifically, it relates to a cable tray with fire extinguishing function. Background Technology

[0002] Cable trays, as a key infrastructure for supporting and protecting cable lines, are widely used in various fields such as power, communications, rail transportation, data centers, and industrial plants. With the continuous improvement of electrification and intelligence, the number, density, and power of cables laid in the trays are increasing day by day, which leads to a significant increase in the risk of fire caused by cables due to overload, short circuit, external fire source intrusion, etc. Moreover, cable fires are characterized by strong concealment, rapid spread, and difficulty in firefighting, posing a great safety threat.

[0003] The patent with publication number CN116667240A discloses an easy-to-assemble earthquake-resistant cable tray and its assembly method, including a cable tray and a controller installed on the outer side of the cable tray; it also includes at least three earthquake-resistant suspension units, at least one pair of cable organizers, multiple temperature node detection modules, a fire extinguisher body, a directional fire extinguishing unit, a pair of isolation components, and a triggering unit; each earthquake-resistant suspension unit includes a pair of wall mounting blocks, a pair of inclined hangers, a bracket, and mounting ears.

[0004] The cable tray in the above solution can immediately form a highly efficient fire extinguishing response in the local area once a fire is confirmed. It can also drive directional fire extinguishing and oxygen isolation measures with the help of the triggering unit, thereby greatly improving the timeliness and accuracy of fire prevention and control. However, in order to successfully isolate oxygen, the cable tray fixes the cable tray to the cover plate to make the inside of the cable tray sealed. This will cause the cable to be unable to dissipate heat, which will increase the cost of the cable's entire life cycle by more than 30%.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a cable tray with fire extinguishing function. If the cable catches fire during the use of the cable tray, the triggering component will immediately contact the fire extinguisher to extinguish the fire. Moreover, the cable tray will be sealed during fire extinguishing, thus preventing heat dissipation from being affected and improving fire extinguishing efficiency.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cable tray with fire extinguishing function includes a cable tray box, a sliding plate slidably connected inside the cable tray box, a placement plate fixedly connected to the sliding plate, a handle fixedly connected to the placement plate, two stabilizing blocks fixedly connected to the placement plate, a fire extinguisher placed between the two stabilizing blocks, and a triggering component for triggering the fire extinguisher on the cable tray box.

[0008] The present invention is further configured such that: the triggering component includes a plurality of sliding rods slidably connected to the cable tray and a cover plate fixedly connected to the upper side of the plurality of sliding rods; the sliding rods are fitted with springs between the cover plate and the cable tray; and the placement plate is provided with a support member for preventing the cover plate from contacting the fire extinguisher.

[0009] The present invention is further configured such that: the support member includes a sleeve fixedly connected to the placement plate and a support rod fixedly connected to the sleeve, the support rod being made of paraffin wax, and the top end of the support rod abutting against the cover plate.

[0010] The present invention is further configured such that a lifting block is slidably connected to the cable tray.

[0011] The present invention is further configured such that an extension rod is fixedly connected to the placement plate.

[0012] The present invention is further configured such that: several partition frames are fixedly connected inside the cable tray.

[0013] In summary, this utility model has the following beneficial effects: if the cable catches fire during the use of the cable tray, the support rod will melt and stop pushing up the cover plate. Then the cover plate will immediately come into contact with the fire extinguisher, triggering the fire extinguisher to extinguish the fire. During the fire extinguishing, the cable tray will be in a sealed state, thus not affecting heat dissipation and improving fire extinguishing efficiency. Furthermore, by setting up a separator, there is a clear separation between the cables, which further improves the fire extinguishing efficiency. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] A type of cable tray with fire extinguishing function, such as Figures 1-4 As shown, the device includes a cable tray 1, a sliding plate 2 slidably connected inside the cable tray 1, a placement plate 3 fixedly connected to the sliding plate 2, a handle 4 fixedly connected to the placement plate 3, two stabilizing blocks 5 fixedly connected to the placement plate 3, and a fire extinguisher 6 placed between the two stabilizing blocks 5 on the placement plate 3. The fire extinguisher 6 can be a carbon dioxide fire extinguisher or a clean gas fire extinguisher. The cable tray 1 is provided with a triggering assembly for triggering the fire extinguisher 6. The triggering assembly includes several sliding rods 7 slidably connected to the cable tray 1 and a cover plate 8 fixedly connected to the upper side of several sliding rods 7. A spring 9 is sleeved between the cover plate 8 and the cable tray 1 on the sliding rods 7. The placement plate 3 is provided with a support to prevent the cover plate 8 from contacting the fire extinguisher 6. The support includes a sleeve 10 fixedly connected to the placement plate 3 and a support rod 11 fixedly connected to the sleeve 10. The support rod 11 is made of paraffin wax, and the top end of the support rod 11 abuts against the cover plate 8. The spring 9 can lift the cover plate 8 to prevent the cover plate 8 from excessively squeezing the support rod 11 and causing deformation of the support rod 11.

[0021] like Figures 1-4 As shown, during cable tray installation, the cable tray 1 is first fixedly connected to the external mounting frame. Then, the cable is passed through the cable tray 1. Next, the mounting plate 3 and sliding plate 2 are lifted by grasping the handle 4, and the sliding plate 2 is inserted into the cable tray 1. The fire extinguisher 6 is inserted between the two stabilizing blocks 5, and the support rod 11 is inserted into the sleeve 10. Several springs 9 are then fitted onto several sliding rods 7. Finally, the cover plate 8 is installed on the cable tray 1. If the cable catches fire after installation, the support rod 11 will melt due to the high temperature. At this time, the support rod 11 will no longer lift the cover plate 8, and the cover plate 8 will slide downwards, pressing down on the fire extinguisher 6, causing the fire extinguisher 6 to spray the extinguishing medium. At this time, the spring 9 is in a compressed state, and the cable tray 1 is sealed. After the extinguishing medium is sprayed out, the oxygen inside the cable tray 1 is isolated, and the extinguishing medium is prevented from leaking out, thereby improving the fire extinguishing efficiency.

[0022] like Figures 1-4As shown, after the fire is extinguished and the staff arrives at the scene, the cover plate 8 and spring 9 can be removed, the damaged cable can be replaced, and after the replacement is completed, the empty fire extinguisher 6 can be taken out and replaced with a new fire extinguisher 6. The new support rod 11 can be inserted into the sleeve 10, and then several springs 9 can be respectively sleeved on several sliding rods 7. Finally, the cover plate 8 can be installed on the cable tray box 1.

[0023] like Figure 1 , Figure 2 , Figure 4 As shown, a lifting block 12 is slidably connected to the cable tray 1. During routine inspections, when it is necessary to check the fire extinguisher 6 and the support rod 11, the cover plate 8 can be manually lifted first, and then the lifting block 12 can be slid so that the lifting block 12 is under the cover plate 8. Then, the handle 4 can be pulled out to pull out the placement plate 3 to check the fire extinguisher 6 and the support rod 11. After the inspection is completed, the handle 4 can be pushed to reset the placement plate 3, and then the lifting block 12 can be pushed to reset the lifting block 12. When the lifting block 12 is reset and no longer in contact with the bottom side of the cover plate 8, the cover plate 8 will slide down due to its own weight and contact the support rod 11.

[0024] like Figure 4 As shown, an extension rod 13 is fixedly connected to the placement plate 3. When the placement plate 3 needs to be reset, the lifting block 12 needs to be pushed to reset first, and then the cover plate 8 needs to be manually lifted before pushing the placement plate 3 to reset. If the lifting block 12 is not pushed to reset, the extension rod 13 will contact the lifting block 12, making it impossible for the placement plate 3 to reset normally. This can avoid the situation where the fire extinguisher 6 cannot be triggered because the lifting block 12 is not pushed to reset after the placement plate 3 is reset.

[0025] like Figures 1-3 As shown, several partitions 14 are fixedly connected inside the cable tray 1, which can clearly separate the cables and further improve the fire extinguishing efficiency.

[0026] Working Principle: During cable tray installation, the cable tray 1 is first fixedly connected to the external mounting frame. Then, each cable is passed through the partitions 14 inside the cable tray 1. Next, the mounting plate 3 and sliding plate 2 are lifted by grasping the handle 4, and the sliding plate 2 is inserted into the cable tray 1. The fire extinguisher 6 is inserted between the two stabilizing blocks 5, and the support rod 11 is inserted into the sleeve 10. Several springs 9 are then fitted onto several sliding rods 7. Finally, the cover plate 8 is installed on the cable tray 1. If the cable catches fire after installation, the support rod 11 will melt due to the high temperature. At this time, the support rod 11 will no longer lift the cover plate 8, and the cover plate 8 will slide downwards, pressing down on the fire extinguisher 6, causing the fire extinguisher 6 to spray the extinguishing medium. At this time, the springs 9 are compressed, and the cable tray 1 is sealed. After the extinguishing medium is sprayed, the oxygen inside the cable tray 1 is cut off, preventing the extinguishing medium from leaking out, thereby improving the fire extinguishing efficiency.
