Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable bridge fire protection, and in particular to a cable bridge based on the application of perfluorohexanone. BACKGROUND

[0002] The cable bridge is an open metal or non-metal structure system for supporting, protecting and organizing various cables, which acts as a "highway" for cable laying. The main functions of the cable bridge include supporting the cables to prevent damage from sagging, providing mechanical protection, neat management for easy maintenance, promoting heat dissipation and planning a safe path. The cable bridge is usually composed of straight sections, bends, supports / hangers, connecting pieces, grounding devices and optional cover plates, partitions and other accessories.

[0003] When the cables in the cable bridge are densely packed, the air circulation will be severely hindered, causing the heat generated by the operation of the cables to be unable to dissipate in time, resulting in a continuous abnormal rise in local temperature. The high-temperature environment will accelerate the thermal aging process of the cable insulation material, making it brittle and cracking, and the insulation performance will rapidly decrease, thereby greatly increasing the probability of short circuit between conductors or between conductors and metal bridges. Once the high-temperature arc or spark produced by the short circuit contacts the deteriorated insulation material, it will quickly ignite the combustible components, and the densely packed cables form a continuous combustible channel, promoting the rapid spread of flames along the bridge, ultimately triggering a fire.

[0004] The perfluorohexanone automatic fire extinguishing sticker installed on the top of the cable bridge can quickly release the extinguishing agent when a fire breaks out inside the bridge, effectively extinguishing the fire source and suppressing the rekindling, providing precise and efficient initial fire protection for the densely packed cable area. Since there are differences in the cable filling amount and layer height inside different cable bridges, the existing perfluorohexanone automatic fire extinguishing sticker installed on the top is installed at a fixed height position, which cannot quickly cover the bottom fire source. SUMMARY

[0043] In order for those skilled in the art to better understand the present application, the present application will be further described in detail below in conjunction with specific embodiments and drawings.

[0044] The terms used in the present application are those general terms currently widely used in the art in consideration of the functions related to the present application, but these terms can be changed according to the intention of those skilled in the art, precedents, or new technology in the art. In addition, specific terms can be selected by the applicant, and in this case, the detailed meaning thereof will be described in the detailed description of the present application. Therefore, the terms used in the specification should not be understood as simple names, but based on the meaning of the terms and the overall description of the present application.

[0045] REFERENCE Figures 1-6 The present embodiment provides a cable tray based on perfluorohexanone application, comprising a tray body 1, which stores cables inside, and a support unit 2 provided at the top position; the support unit 2 comprises a connecting seat 21 fixedly installed on the top of the tray body 1, a fixed plate 22 hinged to the connecting seat 21, a telescopic plate 23 slidingly matched with the fixed plate 22, and a reset member 24 pushing the fixed plate 22 and the telescopic plate 23 away from each other.

[0046] It should be noted that the tray body 1 is made of stainless steel, and the inner and outer surfaces of the tray body 1 are sprayed with intumescent fire paint. The intumescent fire paint foams and expands fifty times rapidly at high temperature of 200-300℃, forming a dense carbonized layer to isolate the internal and external air circulation channels of the tray body 1.

[0047] Specifically, the side wall of the bridge main body 1 is provided with a heat dissipation hole, and the inside of the heat dissipation hole is also sprayed with an intumescent fire paint. When high temperature is encountered, the intumescent fire paint expands and carbonizes rapidly, which can block the heat dissipation hole of the bridge main body 1, effectively prevent oxygen from entering the inside of the bridge main body 1, and inhibit the combustion inside the bridge main body 1.

[0048] Further, in the embodiment, the connecting seat 21 is fixedly connected between the bridge main body 1 through bolts, and the connecting seat 21 is installed at the top position of the bridge main body 1. It should be noted that the number of connecting seats 21 is two, and the two groups of connecting seats 21 are symmetrically arranged along the center line of the bridge main body 1. The fixed plate 22 and the telescopic plate 23 are in sliding fit. The reset member 24 is arranged between the fixed plate 22 and the telescopic plate 23, and the reset member 24 releases elastic potential energy and can push the telescopic plate 23 to move away from the fixed plate 22. At the same time, the reset member 24 can also push the end of the telescopic plate 23 to abut against the side wall of the bridge main body 1.

[0049] The mounting net 3 is connected with the connecting seat 21, and the bottom surface of the mounting net 3 is provided with a fire extinguishing sticker 4. The two ends of the mounting net 3 are respectively connected and fixed with a group of connecting seats 21. The number of fixed plates 22 is at least one group, and one group of fixed plates 22 is relatively staggered. The telescopic plate 23 supports the expansion of the mounting net 3, and the end of the telescopic plate 23 extrudes the mounting net 3 to abut against the side wall of the bridge main body 1. The bottom surface of the mounting net 3 remains flat and covers above the cable.

[0050] Specifically, the number of fixed plates 22 can be multiple groups, and the multiple groups of fixed plates 22 are arranged in linear array, which can satisfy the mounting net 3 with large area and cover the surface of the cable. For details, please refer to the drawings Figure 6 .

[0051] It should be noted that the mounting net 3 is made of spandex, so that the mounting net 3 can extend outward to a certain area. Under normal circumstances, the telescopic plate 23 expands the mounting net 3 and ensures that the bottom surface of the mounting net 3 remains horizontal.

[0052] The device can cope with different scenes when in use: when the height of the cable stacked in the bridge main body 1 is not high, the telescopic plate 23 supports the expansion of the mounting net 3, and ensures that the mounting net 3 is at a certain distance from the bottom of the bridge main body 1, which can be defined as X. And the mounting net 3 is located on the upper surface of the cable. When the height of the cable in the bridge main body 1 increases, the telescopic plate 23 shrinks towards the fixed plate 22, and then the position of the telescopic plate 23 abutting against the mounting net 3 is raised, thereby driving the position of the bottom surface of the mounting net 3 away from the bottom of the bridge main body 1 to increase. At this time, the distance between the bottom surface of the mounting net 3 and the bottom of the bridge main body 1 will be greater than X.

[0053] Further, the end of the fixed plate 22 is installed in a fixed position and is hinged, and the two fixed plates 22 are staggered, and the bottom surface of the mounting net 3 is supported to be kept in a horizontal state by the telescopic plate 23 in sliding fit with the fixed plate 22.

[0054] Specifically, the fire extinguishing sticker 4 is fixed on the bottom surface of the mounting net 3 by adhesion, and the fire extinguishing sticker 4 is a perfluoroketone automatic fire extinguishing sticker, and such products are mature prior art and will not be described in detail here.

[0055] The device can meet the requirement that the number of cables inside the cable bridge is small and the cables are located at a low position inside the cable bridge. When it is necessary to install the fire extinguishing sticker 4 inside the cable bridge, the fixed plate 22 is turned over by the torsional spring, so that the end of the telescopic plate 23 extrudes the mounting net 3 to the side wall position of the bridge body 1. At this time, the mounting net 3 is arranged on the surface of the cable, and when a fire occurs, the fire extinguishing sticker 4 can quickly extinguish the fire by vaporizing perfluoroketone.

[0056] Referring to Figures 1-6 As an optional embodiment, the bridge body 1 includes a wire embedding groove 11 and a cover plate 12, and the cover plate 12 is buckled to the top opening position of the wire embedding groove 11.

[0057] It should be noted that the wire embedding groove 11 and the cover plate 12 are both made of metal, and the cover plate 12 is buckled to the top opening position of the wire embedding groove 11. The cover plate 12 can ensure the closure of the internal space of the wire embedding groove 11, and when a fire occurs, the oxygen inside the wire embedding groove 11 can be quickly consumed, thereby achieving the purpose of inhibiting the further expansion of the fire.

[0058] Further, the number of the connecting seat 21 is one set, and the connecting seat 21 is symmetrically arranged along the center line of the cover plate 12. The end of the fixed plate 22 is connected with a rotating shaft 221, and the rotating shaft 221 is sleeved with a torsional spring 25 outside. The torsional spring 25 can push the fixed plate 22 to turn over to the side away from the cover plate 12.

[0059] It should be noted that in order to further facilitate the quick installation between the connecting seat 21 and the bridge body 1, the surface of the cover plate 12 is provided with a sliding rail, and the connecting seat 21 and the sliding rail are in sliding fit. The worker can quickly push the connecting seat 21 into the sliding rail, and then fix the connecting seat 21 in the sliding rail by using the limiting device, thereby improving the working efficiency of installing the connecting seat 21.

[0060] Specifically, the end of the fixed plate 22 is provided with a rotating shaft 221, and the rotating shaft 221 is in interference fit with the fixed plate 22. The bottom of the connecting seat 21 is provided with a hinge seat, and the rotating shaft 221 penetrates through the through hole of the hinge seat and extends to the outside. The fixed plate 22 can rotate along the axis of the rotating shaft 221.

[0061] Further, the torsion spring 25 is sleeved outside the rotating shaft 221, and the torsion spring 25 comprises two free ends; one end of the torsion spring 25 abuts against the connecting seat 21, and the other end abuts against the fixed plate 22; in the absence of external force, the torsion spring 25 releases elastic force and pushes the fixed plate 22 to turn away from the cover plate 12.

[0062] In the embodiment, when it is needed to cover the cover plate 12 on the top opening position of the wire slot 11, first, the worker needs to pinch the two groups of telescopic plates 23 by hand, so that the spacing between the two telescopic plates 23 can be put into the wire slot 11; then, the hand is released, and the telescopic plate 23 will turn in the direction of the cover plate 12 under the elastic force of the torsion spring 25; at the same time, the end of the telescopic plate 23 will press the mounting net 3 to the side wall of the wire slot 11, and one group of telescopic plates 23 moves away from each other, so that the mounting net 3 can be unfolded, and it is ensured that the mounting net 3 covers the cable inside the wire slot 11.

[0063] Further, the telescopic plate 23 comprises a U-shaped buckle 231, and the U-shaped buckle 231 is fixedly arranged on both sides of the telescopic plate 23; the telescopic plate 23 abuts against the fixed plate 22, and the U-shaped buckle 231 tightly abuts against the side wall of the fixed plate 22.

[0064] It should be noted that, in order to ensure that the telescopic plate 23 will not be separated from the fixed plate 22 in the sliding process, the side wall of the telescopic plate 23 is fixed with the U-shaped buckle 231, and the U-shaped buckle 231 is clamped on the side wall of the fixed plate 22, which can effectively avoid the misalignment between the telescopic plate 23 and the fixed plate 22.

[0065] Specifically, the U-shaped buckle 231 is symmetrically arranged along the center line of the long axis direction of the telescopic plate 23, that is, when the fixed plate 22 and the telescopic plate 23 are combined together, the side wall of the fixed plate 22 is coincident with the end surface of the side wall of the telescopic plate 23.

[0066] Further, the telescopic plate 23 further comprises a through hole 232 penetrating through the surface thereof, and the through hole 232 is arranged at the central position of the telescopic plate 23; the reset member 24 comprises a fixed sleeve 241, a push rod 242 arranged in the fixed sleeve 241, and a spring 243 sleeved outside the push rod 242; the end of the push rod 242 abuts against the end of the fixed plate 22 away from the connecting seat 21.

[0067] It should be noted that the through hole 232 is arranged along the long axis direction of the telescopic plate 23, and the through hole 232 penetrates through the end of the telescopic plate 23 close to the fixed plate 22; the fixed sleeve 241 is fixedly connected with the telescopic plate 23 by bolts, and the fixed sleeve 241 extends to the inside of the through hole 232.

[0068] Specifically, the fixed sleeve 241 is hollow inside, and the push rod 242 is coaxial with the fixed sleeve 241; the push rod 242 comprises a rod part and a head part, the rod part of the push rod 242 is located inside the fixed sleeve 241, the head part of the push rod 242 is fixedly connected with the rod part, and the head part of the push rod 242 abuts against the end of the fixed plate 22 away from the connecting base 21.

[0069] The spring 243 is sleeved outside the push rod 242, and the spring 243 abuts against the inner wall of the fixed sleeve 241 during compression; one end of the spring 243 is connected with the fixed sleeve 241, and the other end is connected with the head part of the push rod 242.

[0070] It should be noted that the fixed plate 22 is fixed at a proper position on the bottom of the cover plate 12 and is hinged with the connecting base 21, the fixed plate 22 can only rotate along the axis of the rotating shaft 221 and cannot move in other directions; when the spring 243 releases the elastic potential energy, the spring 243 pushes the push rod 242 to abut against the fixed plate 22, and since the position of the fixed plate 22 cannot be moved, the spring 243 can only push the telescopic plate 23 to move away from the fixed plate 22.

[0071] The elastic potential energy released by the spring 243 further pushes the end of the telescopic plate 23 away from the fixed plate 22 to push the mounting net 3 to tightly abut against the side wall of the wire slot 11.

[0072] When the cables arranged inside the wire slot 11 are few and the height of the cables is not high; the staff needs to fix the fire extinguishing sticker 4 at the bottom of the mounting net 3, and then needs to cover the cover plate 12 on the top opening position of the wire slot 11; the staff pushes a group of telescopic plates 23 by hand to make the ends of the telescopic plates 23 close to each other, and then places the telescopic plates 23 inside the wire slot 11; then under the action of the elastic force of the torsion spring 25, a group of telescopic plates 23 are driven to move away from each other; the ends of the telescopic plates 23 push the mounting net 3 to abut against the inner wall of the wire slot 11; then the cover plate 12 needs to be continuously pressed to cover the top opening position of the wire slot 11, so that the inside of the wire slot 11 is in a closed state; a group of telescopic plates 23 cooperate to unfold the mounting net 3 and ensure that the surface of the mounting net 3 is flush, and the fire extinguishing sticker 4 arranged at the bottom of the mounting net 3 can extinguish the fire of the cables; and the fire extinguishing sticker 4 is closer to the cables than when it is arranged on the surface of the cover plate 12, and can quickly extinguish the fire source when a fire occurs.

[0073] Referring to Figures 1-6 Figures 1-6 In an embodiment provided in the present application, the adjusting unit 5 comprises a guide rod 51 fixedly connected with the telescopic plate 23, a pressing plate 52 penetrating through the fixed plate 22 and the telescopic plate 23 and cooperating with the guide rod 51, and a stepping plate 53 hinged with the pressing plate 52; the pressing plate 52 comprises a waist hole 521 penetrating through the surface thereof and matched with the guide rod 51.

[0074] In this embodiment, when the cable in the cable trench 11 is stacked more, in order to avoid the installation net 3 completely covering the cable to cause the fire extinguishing sticker 4 to be limited in space when extinguishing the fire, the adjusting unit 5 is increased, when the height of the cable in the cable trench 11 is increased, the position of the installation net 3 is also increased synchronously, thereby ensuring that there is a certain space between the cable and the fire extinguishing sticker 4, and the fire extinguishing sticker 4 is better for extinguishing the fire.

[0075] It should be noted that the pressing plate 52 is in a plate structure, the pressing plate 52 can penetrate through the fixed plate 22 and the telescopic plate 23 and extend to the outside thereof; the waist hole 521 formed on the surface of the pressing plate 52 is matched with the guide rod 51, and the guide rod 51 is fixedly connected between the telescopic plate 23; when the pressing plate 52 penetrates through the surface of the fixed plate 22, the pressing plate 52 is limited by the through groove 222, so that the pressing plate 52 can only move along the through groove 222; through the cooperation between the waist hole 521 and the guide rod 51, the telescopic plate 23 can be further limited, and the telescopic plate 23 and the fixed plate 22 are effectively prevented from being completely separated.

[0076] Further, the end of the pressing plate 52 is provided with a ball head 522, and the inside of the pedal 53 is provided with a rotating groove 531; the ball head 522 is matched with the rotating groove 531; the pedal 53 can be multi-angle flipped relative to the pressing plate 52.

[0077] It should be noted that, since the cross section of the cable is in a circular structure, when the pressing plate 53 abuts against the outer wall of the cable, the pressing plate 53 can not necessarily be in a horizontal state, in order to ensure that the pressing plate 53 abutting against the cable can drive the pressing plate 52 to move, the pressing plate 53 can be rotated relative to the pressing plate 52, that is, even if the pressing plate 53 abuts against the side wall of the cable, the pressing plate 52 can also be pushed to move.

[0078] Further, the pressing plate 52 moves in a direction perpendicular to the surface of the fixed plate 22; the movement of the pressing plate 52 can drive the telescopic plate 23 to move along the long axis direction of the fixed plate 22.

[0079] It should be noted that, during the movement of the pressing plate 52 along the inner wall of the through groove 222, the inner wall of the waist hole 521 formed on the surface of the pressing plate 52 will extrude the guide rod 51 and drive the guide rod 51 to move along the long axis direction of the fixed plate 22; and the guide rod 51 is fixedly connected with the telescopic plate 23, so that when the guide rod 51 moves, the telescopic plate 23 can be driven to move synchronously.

[0080] Further, the bottom surface of the pedal 53 abuts against the installation net 3 and is limited by the cable; the pedal 53 moves upward to drive the telescopic plate 23 to move upward along the side wall of the cable trench 11, so that the bottom surface of the installation net 3 moves toward the cover plate 12.

[0081] The end of the telescopic plate 23 away from the fixed plate 22 is provided with a fixed end 233; the number of the fire extinguishing stickers 4 is multiple groups, and the multiple groups of fire extinguishing stickers 4 are fixed at the bottom position of the installation net 3.

[0082] Further, the fixed end 233 is fixedly connected with the mounting net 3. In the embodiment, the mounting net 3 includes flexible parts fixed on both sides of the connecting seat 21 and a fiber part located in the middle of the two flexible parts; the fiber part has no ability of tensile deformation; the flexible parts of the mounting net 3 can change their tensile state along with the change of the position of the telescopic plate 23.

[0083] When the height of the cables accumulated in the wire slot 11 is high, the pedal 53 will be pushed upward by the cables during the process of covering and covering the cover plate 12, so that the pedal 53 moves upward, and the pedal 53 can push the pressing plate 52 to move along the inner wall of the through groove 222 at the same time; the movement of the pressing plate 52 can drive the telescopic plate 23 to move along the long axis direction of the fixed plate 22; and then the telescopic plate 23 moves to the direction close to the fixed plate 22, and the torsional spring 25 releases the elastic potential energy to further drive the telescopic plate 23 to flip to the side close to the cover plate 12, so that the telescopic plate 23 is closer to the cover plate 12; since the telescopic plate 23 always needs to press the mounting net 3 to abut against the side wall of the wire slot 11, when the position of the end part of the telescopic plate 23 moves upward, the bottom surface of the mounting net 3 also moves upward at the same time, and then the fire extinguishing sticker 4 can be lifted to a distance from the cables, which is helpful to better extinguish the fire.

[0084] Finally, it should be pointed out that the methods and devices described in detail above are only embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present application.

[0085] It is important to note that the above embodiments are only used to illustrate the technical solutions of the present application and not to limit it. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the present application, and they should be covered in the scope of the claims of the present application.
