Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a fireproof cable tray. Background Technology

[0002] The core significance of fire-resistant cable trays lies in building a fire safety barrier. Through fire-resistant materials and structural design, they slow down the burning speed of the cable trays and cables in a fire, preventing the fire from spreading along the cables and buying time for personnel evacuation and fire rescue. At the same time, they can ensure the continuous operation of critical cables during a fire, maintain the normal operation of the fire protection system, and reduce loss of life and property. They are an important part of electrical safety in modern building fire protection systems.

[0003] Fire-resistant cable trays achieve fire resistance through fire-resistant materials and structural design. They utilize fire-retardant coatings, flame-retardant boards, and other fire-resistant materials. When exposed to fire, the coating expands to form an insulating layer, or the boards block heat conduction. Their multi-layered composite structure slows heat transfer to the cables, while the sealed design prevents flame spread. The key lies in utilizing the flame-retardant and heat-insulating properties of the materials to maintain structural stability during a fire, extend the normal operating time of the cables, and prevent the fire from spreading along the cable channels.

[0004] In existing technologies, some fire-resistant cable trays cannot actively isolate oxygen. When the cable itself spontaneously combusts or the external fire exceeds the fire resistance limit of the fireproof layer, the fireproof layer will fail due to high-temperature carbonization and peeling, and cannot prevent the fire from directly damaging the cable. It only relies on the fire resistance of the material to delay the fire and has no fire extinguishing ability. Therefore, a fire-resistant cable tray is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a fireproof cable tray, which aims to improve the problem that existing fireproof cable trays cannot actively isolate oxygen, rely only on the fire resistance of materials to delay the spread of fire, and have no fire extinguishing ability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fireproof cable tray includes a base, with two mounting slots on the inner wall of the base, temperature sensing elements installed on the inner walls of the two mounting slots, and baffles fixedly connected to the outer walls of the temperature sensing elements. The inner wall of the base has two storage slots, and the outer wall of the base has multiple fixing slots. The inner walls of the two storage slots are provided with flame retardant. The outer wall of the baffle is slidably connected to the inner wall of the storage slots. A connecting device for connection is installed on the outer wall of the base.

[0008] As a further description of the above technical solution:

[0009] The connecting device includes a top cover, the bottom of which is slidably connected to the outer wall of the base. The inner wall of the top cover has two movable grooves, and the inner walls of the two movable grooves are slidably connected to connecting rods. The outer walls of the connecting rods are fixedly connected to a stop block, and the outer walls of the stop block are fixedly connected to a fixed shaft.

[0010] As a further description of the above technical solution:

[0011] The inner wall of the base is detachably connected to a fixing frame, and the inner wall of the fixing frame is detachably connected to a cable;

[0012] As a further description of the above technical solution:

[0013] A slider is fixedly connected to the outer wall of the base, and a groove is opened on the outer wall of the base;

[0014] As a further description of the above technical solution:

[0015] The outer wall of the baffle is slidably connected to the inner wall of the mounting groove, and the outer wall of the slider is slidably connected to the inner wall of the slide groove.

[0016] As a further description of the above technical solution:

[0017] A return spring is fitted on the outer wall of the fixed shaft, and the other end of the return spring is fixedly connected to the inner wall of the movable groove.

[0018] As a further description of the above technical solution:

[0019] The outer wall of the connecting rod is slidably connected to the inner wall of the top cover, and the outer wall of the stop is slidably connected to the inner wall of the fixing groove.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when a fire occurs and fire extinguishing and flame retardancy are required, the temperature sensing element detects the high temperature, and the internal thermal expansion liquid rapidly expands, causing its outer wall to rupture. This causes the baffle to fall down along the mounting groove and slide out of the storage tank, allowing the flame retardant in the tank to slide outward into the base to cover the cable. If the cable spontaneously combusts, the flame retardant isolates oxygen to extinguish the fire; when the outside catches fire, it forms a protective layer to protect the cable. This structure is simple and reliable, relying on the physical principle of thermal expansion and the linkage of mechanical structures to reduce the risk of failure.

[0022] 2. In this utility model, when multiple bases need to be connected, the slider of one base is precisely aligned with the groove of another base and slid in. Then, the top cover is slid in along the outer wall of the base, and the connecting rod is pressed inward to drive the stop block to retract outward. After the top cover is slid in, the stop block is inserted into the fixing groove by the reset spring. Multiple bases are firmly connected by snap-fit ​​fixing. This structure ensures connection stability and reliability and facilitates the disassembly and maintenance of cables in the later stage. Attached Figure Description

[0029] 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.

[0030] Reference Figures 1 to 3 This utility model provides an embodiment of a fireproof cable tray, including a base 1, which provides an installation environment for subsequent connections. Two mounting grooves 2 are formed on the inner wall of the base 1, providing an installation environment for subsequent parts. Temperature sensors 3 are installed on the inner walls of the two mounting grooves 2. If the temperature sensor 3 becomes too high, it indicates a fire and breaks. A baffle 4 is fixedly connected to the outer wall of the temperature sensor 3, fixing a flame-retardant material 6. Two storage grooves 5 are formed on the inner wall of the base 1, holding the flame-retardant material 6. Multiple fixing grooves 16 are formed on the outer wall of the base 1, fixing blocks 13. The flame-retardant material 6 is provided on the inner walls of the two storage grooves 5, blocking flames. The outer wall of the baffle 4 is slidably connected to the inner wall of the storage grooves 5. A connecting device for connection is installed on the outer wall of the base 1.

[0031] The inner wall of the base 1 is detachably connected to a fixing frame 7, which fixes the cable. The inner wall of the fixing frame 7 is detachably connected to a cable 8, which is a protected target. The outer wall of the base 1 is fixedly connected to a slider 9, which connects to a slide groove 10 to connect multiple bases 1. The outer wall of the base 1 has a slide groove 10, which connects to the slider 9 to connect multiple bases 1. The outer wall of the baffle 4 is slidably connected to the inner wall of the mounting groove 2, and the outer wall of the slider 9 is slidably connected to the inner wall of the slide groove 10.

[0032] Reference Figures 2 to 3 The connecting device includes a top cover 11, which provides an installation environment for subsequent parts. The bottom of the top cover 11 is slidably connected to the outer wall of the base 1. The inner wall of the top cover 11 has two movable slots 17, which provide an installation environment for subsequent parts. The inner walls of the two movable slots 17 are slidably connected to a connecting rod 12, which drives the stop block 13 to slide. The outer wall of the connecting rod 12 is fixedly connected to the stop block 13. After the stop block 13 is connected to the fixed slot 16, it fixes multiple bases 1. The outer wall of the stop block 13 is fixedly connected to a fixed shaft 14, which fixes the return spring 15.

[0033] A reset spring 15 is sleeved on the outer wall of the fixed shaft 14. The reset spring 15 resets the stop block 13. The other end of the reset spring 15 is fixedly connected to the inner wall of the movable groove 17. The outer wall of the connecting rod 12 is slidably connected to the inner wall of the top cover 11. The outer wall of the stop block 13 is slidably connected to the inner wall of the fixed groove 16.

[0034] Working Principle: When a fire occurs requiring fire extinguishing and flame retardant treatment, the temperature sensing element 3 detects the high temperature of the ignition point. The thermally expanding liquid inside rapidly expands, and as the pressure increases, the outer wall of the temperature sensing element 3 eventually ruptures. This causes the baffle 4 to fall vertically along the inner wall of the mounting groove. As the baffle 4 falls, it slides out of the inner wall of the storage tank 5, causing the flame retardant material 6 on the inner wall of the storage tank 5 to slide outwards and quickly into the base, evenly covering the cable. If the cable spontaneously combusts, the flame retardant can isolate oxygen to extinguish the fire; if an external fire occurs, the flame retardant forms a protective layer, protecting the cable from flame attack. This structure is simple and reliable, requiring no complex electronic components or control systems, relying solely on the physical principle of thermal expansion and mechanical structure linkage to reduce the risk of failure.

[0035] When multiple bases 1 need to be connected, the slider 9 of one base 1 is precisely aligned with the slide groove 10 of another base 1. The slider 9 is then smoothly slid into the slide groove 10. The top cover 11 is then slid in along the outer wall of the base 1. At this point, the connecting rod 12 needs to be pressed inward to move the stop block 13 outward, allowing the top cover 11 to slide into the outer wall of the base 1. When the stop block slides into the fixing groove 16, the return spring 15 causes the stop block 13 to insert into the inner wall of the groove 16. Through this snap-fit ​​fixing method, multiple bases 1 are firmly connected together. This structure ensures the stability and reliability of the connection structure and facilitates the disassembly and maintenance of cables later.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
