Description

Technical Field

[0001] This utility model relates to the technical field of cable laying protection devices, specifically to a metal armored isolation cable fireproof device, which is suitable for power plants, substations, power distribution rooms and other places. Background Technology

[0002] Cable trenches are indispensable infrastructure in power plants, substations, and other similar locations. They are primarily used to lay and protect cables, and the environment within the trench is closely related to the safe operation of the cables and the extent of damage from faults. Taking substations as an example, cables are distributed throughout the entire substation, their main function being the transmission of energy and signals. The selection of cable routes should avoid various forms of damage and corrosion to the cables, and should avoid areas requiring excavation for planned construction projects. Cable laying plays a crucial role in these locations, not only affecting the stable operation of the power system but also directly impacting the safety and lifespan of equipment. Therefore, when laying cables, relevant standards and specifications must be strictly adhered to to ensure high-quality installation and maintenance.

[0003] However, currently, there are many cables laid out in cable trenches, which have poor fire resistance, mainly because they are prone to flame spread. Utility Model Content

[0004] The purpose of this invention is to provide a metal-armored, isolated cable fireproof device with a reasonable structure and reliable use, which solves the problem that a large number of cables in a cable trench can easily cause the spread of flames, greatly improves the fireproof performance, and significantly reduces fire losses in the event of a fire.

[0005] The technical solution of this utility model is: A metal-armored, partitioned cable fireproof device includes a fireproof sealing assembly installed in a cable trench. The key technical features are: the fireproof sealing assembly includes multiple uprights spaced along the length of the cable trench and fixed to the sidewalls of the trench; multiple crossbeams spaced along the height of the uprights; and a pull-out right-angle partition plate overlapping between two adjacent crossbeams in the horizontal direction. Multiple overlapping grooves are symmetrically provided on both sides of the crossbeams. The horizontal ends of the pull-out right-angle partition plate overlap the overlapping grooves of the crossbeams. The vertical ends of the pull-out right-angle partition plate are abutted against the free ends of the crossbeams. The vertical ends of two adjacent pull-out right-angle partition plates overlap each other, forming a cable laying channel in a horizontally adjacent row. The pull-out right-angle partition plate is composed of a fireproof board and a metal armor layer covering the outside of the fireproof board.

[0006] The aforementioned metal armored cable fireproof device has a C-shaped steel column, with a corresponding crossbeam socket on the side wall of the column. The end of the crossbeam has a locking block that mates with the socket. The locking block is inserted into the socket and welded to the column for fixation.

[0007] The aforementioned metal-armored, partitioned cable fireproof device has a row of pull-out right-angle partition panels supported between two adjacent rows of crossbeams, with the two adjacent rows of pull-out right-angle partition panels arranged in a connected manner.

[0008] The aforementioned metal-armored, partitioned cable fireproof device has a top plate consisting of a pull-out right-angle partition panel at the top, which is not used for cable installation.

[0009] The aforementioned metal armored partition cable fireproof device has a corresponding clearance opening for the column at the front edge of the horizontal panel of the pull-out right-angle partition plate, and the front edge of the horizontal panel extends to the side wall of the cable trench.

[0010] In the aforementioned metal-armored, partitioned cable fireproof device, a transmission roller assembly is provided on the horizontal surface of the pull-out right-angle partition plate, and the center line of the rollers of the transmission roller assembly is perpendicular to the side wall of the cable trench.

[0011] The beneficial effects of this utility model are: A multi-row, pull-out right-angle partition panel forms a multi-layered cable laying space. The pull-out right-angle partition panel is composed of a fireproof board and a metal armor layer, which can isolate flames and heat. The effective combination of the metal armor layer and the fireproof board prevents external flames from directly contacting the cables, isolating the cable channel from other areas and limiting the spread of fire. This utility model can be used for layered isolation of power cables, control cables, communication cables, optical fibers, etc. In the event of a fire, it prevents the spread of flames to other cable layers, effectively protecting the reliable operation of each layer of cables, ensuring the safe and reliable transmission of power, and avoiding major accidents caused by fire.

[0014] The present invention will be described in detail with reference to the accompanying drawings. Example

[0015] like Figure 1 , Figure 2 As shown, the metal-armored, isolated cable fireproof device includes a fireproof sealing component installed in the cable trench.

[0016] Wherein: the fireproof sealing component includes multiple columns 1 arranged at intervals along the length of the cable trench and fixed to the side wall of the cable trench, multiple crossbeams 3 arranged at intervals along the height of the columns 1, and a pull-out right-angle partition 2 that overlaps between two adjacent crossbeams 3 in the horizontal direction.

[0017] The crossbeam 3 has symmetrically arranged multi-layer overlapping grooves 301 on both sides. The horizontal surfaces 201 of the pull-out right-angle partition 2 overlap in the overlapping grooves 301 of the crossbeam 3, and the vertical surfaces 202 of the pull-out right-angle partition 2 are attached to the free ends of the crossbeam 3. The multi-layer overlapping grooves 301 are designed to adjust the overlap height. The vertical surfaces 202 of two adjacent pull-out right-angle partitions 2 are stacked together, and a row of horizontally adjacent pull-out right-angle partitions 2 forms a cable laying channel. A row of pull-out right-angle partitions 2 is supported between two adjacent rows of crossbeams 3, and the two adjacent rows of pull-out right-angle partitions 2 are arranged together. The top pull-out right-angle partition 2 is the top plate and is not used for cable laying.

[0018] In this embodiment, the column 1 is a C-shaped steel structure. The side wall of the column 1 is provided with a corresponding slot for the crossbeam 3. The end of the crossbeam 3 is provided with a locking block 302 that cooperates with the slot. The locking block 302 is inserted into the slot and welded to the column 1 for fixation.

[0019] The pull-out right-angle partition 2 is composed of a fireproof board and a metal armor layer covering the outside of the fireproof board. The front edge of the horizontal panel 201 of the pull-out right-angle partition 2 is provided with a clearance opening corresponding to the column 1, and the front edge of the horizontal panel 201 extends to the side wall of the cable trench.

[0020] Working principle: 1. When in use, this utility model shall be arranged along the two side walls of the cable trench, with a passageway for workers to walk in the middle.

[0021] 2. This utility model can be arranged from bottom to top, and multiple layers of cables can be laid from bottom to top.

[0022] 3. When a fire occurs on a certain layer of cable, the upper and lower layers of the cable laying channel are isolated by the pull-out right-angle partition 2, which greatly slows down the spread of the flames, achieves the purpose of fire prevention, and greatly reduces economic losses.

[0023] 4. When a fire occurs in the cables on a certain floor, pull out the pull-out right-angle partition 2 of the corresponding floor to extinguish the fire on that floor. Example

[0024] like Figure 3 , Figure 4 As shown, in this embodiment, a transmission roller group 4 is provided on the horizontal surface 201 of the pull-out right-angle partition 2, and the center line of the rollers of the transmission roller group 4 is perpendicular to the side wall of the cable trench. The transmission roller group 4 on the horizontal surface 201 of the pull-out right-angle partition 2 helps to reduce the friction of cable laying, saving time and effort.

[0025] Everything else is the same as in Example 1.

[0026] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this utility model.
