Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, specifically a fireproof and flame-retardant cable tray. Background Technology

[0002] As is generally known, cable trays are classified into trough-type, tray-type, ladder-type, and mesh-type structures, consisting of supports, brackets, and installation accessories. Cable trays within buildings can be installed independently or attached to various building and pipe rack supports. They should feature simple structure, aesthetically pleasing appearance, flexible configuration, and convenient maintenance. All parts must be galvanized. Cable trays installed outdoors are considered to be rigid structural systems that provide close support for cables, consisting of straight sections, bends, tees, and crosses of trough-type, tray-type, or ladder-type structures, as well as brackets and hangers.

[0003] For example, the utility model patent with application publication number CN208423662U, application publication date of January 22, 2019, and titled "A Fireproof Cable Tray", has the following specific structure: cable tray body, first fireproof and flame-retardant plate, and cover plate. The inner wall of the cable tray body is coated with a fireproof coating. A front edge plate is installed on the top of the cable tray body. The first fireproof and flame-retardant plate is installed on the inner side of the first U-shaped mounting plate and the second U-shaped mounting plate. A second fireproof and flame-retardant plate is installed on the top of the first support plate. The inside of the cable tray body below the second fireproof and flame-retardant plate is filled with fireproof and flame-retardant material. A third fireproof and flame-retardant plate is installed on the top of the second support plate. A cover plate is installed on the top of the front edge plate. A limit plate is installed on one side of the cable tray body, and a limit groove is provided on the other side of the cable tray body.

[0004] The shortcoming of the existing technology is that the first, second and third fire-retardant plates in the cable tray are used to surround and protect the cables in the cable tray, so as to play a role in flame retardant and fire prevention when the cables catch fire. However, since multiple fire-retardant plates seal and protect the cables in the cable tray, the cables will generate heat during use. The heat will accumulate in the cable tray and is difficult to dissipate, which will easily lead to high temperature damage to the cables in the cable tray. Utility Model Content

[0005] The purpose of this invention is to provide a fire-resistant and flame-retardant cable tray to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fireproof and flame-retardant cable tray, comprising a cable tray and a cover fixedly installed thereon, wherein a U-shaped flame-retardant seat is fixedly installed inside the cable tray, and through grooves are arrayed on both the cable tray and the flame-retardant seat; flame-retardant plates are symmetrically fixedly connected to the cover via hot-melt seats, and the flame-retardant plates are provided with connecting grooves aligned with the through grooves; the hot-melt seats melt to separate the flame-retardant plates from the cover and insert them into the flame-retardant seat, and the connecting grooves and through grooves are misaligned and separated.

[0007] As a further description of the above technical solution: the hot melt base is fixedly provided with a plug-in part that is inserted into the end of the flame retardant base.

[0008] As a further description of the above technical solution: the flame-retardant base is symmetrically provided with fitting grooves, the cover is symmetrically fixed with guide slides, and the flame-retardant plate is parallel to the guide slides with its end located in the fitting groove.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] Example 1

[0027] Combination Figure 1 and Figure 2As shown, this embodiment improves the flame-retardant structure based on the original cable tray. Specifically, a flame-retardant seat 3 is installed inside the cable tray 1, and a flame-retardant plate 5 is installed on the cover 2. When the cover 2 is installed on the cable tray 1, the flame-retardant plate 5 extends into the inside of the flame-retardant seat 3, so that the connecting groove 51 of the flame-retardant plate 5 is aligned and connected with the through groove 91 of the cable tray 1 and the flame-retardant seat 3. At this time, the connecting groove 51 and the flame-retardant seat 3 can serve as ventilation grooves for the cable tray 1 to dissipate heat from the cables inside the cable tray 1. If the cables inside the cable tray 1 heat up to the combustion temperature, the heat-melting seat 4 is melted and destroyed, causing the flame-retardant plate 5 to detach from the cover 2. At this time, the cover 2 slides into the flame-retardant seat 3 to separate the through groove 91 from the connecting groove 51, thereby sealing the cables inside the cable tray 1 to reduce the entry of external air, and using the flame-retardant seat 3 and the flame-retardant plate 5 to achieve fire prevention and flame retardancy for the cables.

[0028] Specifically, the flame-retardant base 3 has several placement slots 31 for placing and installing cables. The flame-retardant base 3 is U-shaped to fit the inner wall of the cable tray 1. The cable tray 1 has threaded holes, and the cover 2 has through holes. The cover 2 can be fixedly installed onto the cable tray 1 by bolts 8.

[0029] In the above technical solution, the flame-retardant plate 5 connected to the cover 2 by the hot melt seat 4 is used. When the internal temperature of the cable tray 1 is normal, the connecting groove 51 of the flame-retardant plate 5 and the through groove 91 on the cable tray 1 and the flame-retardant seat 3 serve as ventilation grooves to dissipate heat from the cables in the cable tray 1. If the internal temperature of the cable tray 1 rises to the combustion temperature, the hot melt seat 4 is heated and melted, causing the flame-retardant plate 5 to separate from the cover 2, and the through groove 91 is separated from the connecting groove 51, thereby completing the fire prevention and flame retardant protection of the cables in the cable tray 1.

[0030] Example 2

[0031] Combination Figure 2 As shown, this embodiment improves upon the first embodiment by modifying the hot melt base 4. When the cover 2 is installed on the cable tray 1, the hot melt base 4 is inserted into the U-shaped end of the flame retardant base 3, thereby further improving the installation stability between the flame retardant base 3 and the flame retardant plate 5. When the temperature inside the cable tray 1 rises, the hot melt base 4 melts, allowing part of the hot melt base 4 to melt into the gap between the flame retardant base 3 and the cover 2, thereby further sealing the top of the inner cavity of the cable tray 1 and preventing external air from entering and causing internal fire.

[0032] Specifically, the plug-in part 41 and the hot melt base 4 are integrally formed, and the two U-shaped ends of the hot melt base 4 are provided with plug-in grooves that cooperate with the plug-in part 41.

[0033] Example 3

[0034] Combination Figure 2As shown, this embodiment improves the installation structure of the flame-retardant plate 5 based on the first embodiment. When the temperature inside the cable tray 1 rises, the hot melt seat 4 is damaged so that the flame-retardant plate 5 is separated from the cover 2. The flame-retardant plate 5 can slide along the surface of the guide slide 21 and detach from the cover 2, so that the flame-retardant plate 5 can be further slid into the fitting groove 32, ensuring further fitting and flame-retardant protection between the flame-retardant plate 5 and the flame-retardant seat 3.

[0035] Specifically, when the flame-retardant plate 5 is connected to the cover 2 through the hot melt seat 4, the flame-retardant plate 5 is attached to the guide slide 21 so that the end of the flame-retardant plate 5 can be embedded in the fitting groove 32 of the flame-retardant seat 3. Thus, when the cover 2 and the bridge body 1 are installed as one unit, the flame-retardant plate 5 and the flame-retardant seat 3 cooperate to improve the installation stability between the two and ensure the stable connection between the connecting groove 51 and the through groove 91 to achieve stable heat dissipation of the cables in the cable tray 1.

[0036] Example 4

[0037] Combination Figure 2 As shown, this embodiment provides an additional airbag component 6 based on embodiment one. When the internal cable of the cable tray 1 heats up to the combustion temperature, the heat-melting seat 4 is melted and destroyed by heat, so that the flame-retardant plate 5 is separated from the cover 2. At this time, the cover 2 slides into the flame-retardant seat 3 to separate the through groove 91 from the connecting groove 51. At this time, the airbag component 6 on the flame-retardant plate 5 slides to align with the through groove 91. The high temperature inside the cable tray 1 will cause the airbag component 6 to expand due to heat and extend into the through groove 91, thereby sealing the through groove 91 and further preventing external air from entering the cable tray 1 and causing the cable tray 1 to catch fire.

[0038] Specifically, the airbag components 6 are fixedly arranged in a rectangular array on the flame-retardant plate 5. The airbag components 6 and the flame-retardant plate 5 can be connected by glue, and the number of airbag components 6 is the same as that of the through groove 91.

[0039] Example 5

[0040] Combination Figure 3 As shown, this embodiment improves the flame-retardant plate 5 and flame-retardant seat 3 based on embodiment 3. When the temperature inside the cable tray 1 rises to the combustion temperature, the hot melt seat 4 melts, causing the flame-retardant plate 5 to separate from the cover 2. The flame-retardant plate 5 slides into the fitting groove 32, so that the fitting groove 52 and the protrusion 33 are inserted and engaged, thereby completing the further sealing connection between the flame-retardant seat 3 and the flame-retardant plate 5, and improving the flame-retardant ability of the flame-retardant seat 3 and the flame-retardant plate 5 inside the cable tray 1.

[0041] Specifically, the mating groove 52 is provided at the end of the flame-retardant plate 5 facing the fitting groove 32, and the end of the flame-retardant plate 5 is located inside the fitting groove 32 so that the mating groove 52 is aligned with the protrusion 33.

[0042] Example 6

[0043] Combination Figure 3 As shown, this embodiment provides an additional liquid storage bladder 7 based on embodiment five. When the temperature inside the cable tray 1 rises to the combustion temperature, the hot melt seat 4 melts, causing the flame retardant plate 5 to separate from the cover 2, and the flame retardant plate 5 slides into the fitting groove 32, so that the fitting groove 52 and the protrusion 33 are inserted and engaged. At this time, the puncture tip 53 can puncture the liquid storage bladder 7 so that the water stored in the liquid storage bladder 7 overflows into the fitting groove 32, thereby completing the further sealing between the flame retardant plate 5 and the flame retardant seat 3, and the overflowing water can be heated and evaporated to further reduce the temperature inside the cable tray 1 and improve the fire resistance of the inside of the cable tray 1.

[0044] Specifically, the reservoir 7 can store water or other fire-retardant liquids.

[0045] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
