Description

TECHNICAL FIELD

[0001] The present application relates to cable shaft installation technology, in particular to a cable shaft based on perfluorohexanone fire extinguishing material. BACKGROUND

[0002] As a core component of modern building electrical systems, the vertical channel function of the cable shaft mainly provides vertical wiring paths for power cables, communication cables and other cross-floor paths. This structure connects power distribution equipment or communication equipment on different floors, realizing hierarchical layout of strong and weak electrical systems. To ensure safe operation, the shaft is usually fixed by cable bridge or special support, and strong current cables (high voltage, large current) and weak current cables (communication, signal) need to be strictly separated and laid to avoid the influence of electromagnetic interference on signal transmission quality.

[0003] In terms of fire protection, the design of the cable shaft needs to follow strict fire protection specifications. Fireproof partitions are provided at each floor, and physical isolation is achieved by fireproof mortar, fire-retardant sealant and other materials at the cable crossing, forming vertical fireproof partitions. It is worth noting that the cable itself is a potential fire source, and its outer layer often needs to be sprayed with fire-retardant paint or coated with fire-retardant sheath to enhance fire-retardant performance. However, although this type of fire protection can effectively delay the spread of fire, the fire-retardant coating will sacrifice the original mechanical flexibility of the cable, making it more prone to stress concentration during frequent stretching, bending or twisting operations during installation. And under the condition that the existing support is in a vertical rigid clamping mode, long-term bending stress of the cable will easily cause material fatigue accumulation. This contradiction between rigid constraint and dynamic deformation of the cable may lead to the risk of fire-retardant coating falling off, thereby weakening the overall fire protection performance and increasing maintenance costs. SUMMARY

[0004] Therefore, the technical problem to be solved by the present application is to solve the problem of existing vertical shaft support using vertical rigid clamping, which easily causes the risk of cable fire-retardant coating falling off.

[0005] The above technical problem is solved by the following technical scheme: the present application proposes a cable shaft based on perfluorohexanone fire extinguishing material, which includes a support unit, including a vertical stand embedded around the side wall of the vertical shaft, a cross arm fixed to the inner side of the vertical stand, a side stand fixed to the other side of the vertical stand, and a plurality of groups of row stands fixed to the end face of the cross arm at equal intervals;

[0006] The interval unit includes a sliding rail fixed to one side of the row stand;

[0007] The fixing unit includes a sliding block slidingly arranged in the inner side of the sliding rail, a clamping table hingedly connected to the inner side of the sliding block, a tightening member clamped in the inner side of the clamping table, and a plurality of groups of confinement members arranged on both sides of the end portion of the clamping table;

[0009] In a preferred embodiment of the cable shaft based on the perfluorohexone fire extinguishing material of the present application, a perfluorohexone coating is externally applied to the cable.

[0010] In a preferred embodiment of the cable shaft based on the perfluorohexone fire extinguishing material of the present application, the sliding block comprises a clamping plate slidingly clamped inside the sliding rail, a plurality of sets of one-way rollers equally spaced and slidingly clamped inside the clamping plate, and a rotating member clamped to the axis of the one-way rollers.

[0011] In a preferred embodiment of the cable shaft based on the perfluorohexone fire extinguishing material of the present application, the clamping table comprises a mounting plate, a centering block protruding from the end of the mounting plate, a connecting bolt for fixedly connecting the sliding block, and an avoiding circular groove provided at the axis of the mounting plate.

[0012] The rotating member is slidingly clamped inside the avoiding circular groove.

[0013] In a preferred embodiment of the cable shaft based on the perfluorohexone fire extinguishing material of the present application, the confinement member comprises a telescopic rod arranged in a circumferential array at the end of the mounting plate, a flexible binding plate fixed to one side of the telescopic rod, and a bolt block provided at one end of the flexible binding plate.

[0014] In a preferred embodiment of the cable shaft based on the perfluorohexone fire extinguishing material of the present application, the mounting plate comprises a slot for fixing the bolt block, a slot hole for radially limiting the telescopic rod, and a ring groove for accommodating the tightening member.

[0015] In a preferred embodiment of the cable shaft based on the perfluorohexone fire extinguishing material of the present application, the tightening member comprises a ring tooth clamped inside the ring groove, and a driving rod engaged outside the ring tooth.

[0016] In a preferred embodiment of the cable shaft based on the perfluorohexone fire extinguishing material of the present application, the driving rod comprises a driving wheel engaged with the ring tooth, and a rectangular block protruding from the end of the driving wheel.

[0017] In a preferred embodiment of the cable shaft based on the perfluorohexone fire extinguishing material of the present application, the telescopic rod comprises a nut radially clamped inside the slot hole, a screw threadedly connected inside the nut, and a rotating cap circumferentially limited inside the end of the screw.

[0018] In a preferred embodiment of the cable shaft based on the perfluorohexone fire extinguishing material of the present application, the screw is provided with a clamping hole consistent with the cross-sectional shape of the rectangular block.

[0019] The beneficial effects of the present invention are: through the setting of the one-way roller and the rotating part, combined with the rotational adaptation of the avoidance circular groove of the clamping table and the connecting bolt, the flexible adjustment of the cable installation angle and the automatic reinforcement function triggered by sliding are realized. The one-way sliding of the slider along the slide rail can drive the rotating part to rotate, and then through the engagement of the ring teeth and the drive rod, the shaking of the cable is converted into the axial displacement of the restraining part, so that the flexible bundle plate fits the cable surface in real time. Ensure that the restraining part can still maintain a stable lock after dynamic adjustment, significantly improving the redundant safety of cable clamping. In addition, the coating process of the perfluorohexanone coating and the wavy texture of the flexible bundle plate synergistically optimize the diffusion efficiency of the fire extinguishing agent, so that the cable can quickly form a gaseous protective barrier in a fire scene, blocking the fire spread path.

[0030] Referring to Figures 1-7 , the embodiment provides a cable shaft based on perfluorohexanone fire extinguishing material, comprising a support unit 1, a vertical stand 11 inlaid around the shaft wall, a cross arm 12 fixedly arranged on the inner side of the vertical stand 11, a side stand 13 fixedly arranged on the other side of the vertical stand 11, and a plurality of groups of row stands 14 fixedly arranged at equal intervals on the end surface of the cross arm 12;

[0031] The spacing unit 2 comprises a sliding rail 21 fixedly arranged on one side of the row stand 14;

[0032] The fixing unit 3 comprises a sliding block 31 slidingly arranged on the inner side of the sliding rail 21, a clamping table 32 hingedly arranged on the inner side of the sliding block 31, a tightening member 33 clamped on the inner side of the clamping table 32, and a plurality of groups of confinement members 34 arranged on both sides of the end of the clamping table 32;

[0033] The cable 4 is clamped on the inner side of the fixing unit 3.

[0034] Further, the cable 4 is externally coated with a perfluorohexanone coating layer 41.

[0035] Further, the sliding block 31 comprises a clamping plate 311 slidingly clamped on the inner side of the sliding rail 21, a plurality of groups of one-way rollers 312 slidingly clamped on the inner side of the clamping plate 311 at equal intervals, and a rotating member 313 clamped on the shaft of the one-way roller 312.

[0036] Further, the clamping table 32 comprises a mounting plate 321, a centering block 322 protruding from the end of the mounting plate 321, a connecting bolt 323 for fixedly connecting the sliding block 31, and an avoidance circular groove 324 arranged at the shaft of the mounting plate 321;

[0037] The rotating member 313 is slidingly clamped in the avoidance circular groove 324.

[0038] In the embodiment, as Figure 1As shown, the support unit 1 is the core support frame of the cable shaft, which is a three-dimensional grid structure composed of vertical supports 11, cross beams 12, side supports 13 and row supports 14. The rectangular slot is well bonded with concrete. The vertical support 11 is a H-shaped steel frame extending in the vertical direction, and its two side edges are welded and fixed with the embedded steel plate of the shaft side wall through anchor bolts, forming a rigid embedded structure. The transverse section of the vertical support 11 is a rectangular hollow structure, and the inside is reserved with threaded holes for the subsequent installation of the cross beam 12 and the side support 13. The cross beam 12 is a horizontally extending I-beam, and its two ends are connected with the inside flange plate of the vertical support 11 through bolt set, forming a horizontal support layer. The upper surface of the cross beam 12 is provided with equally spaced clamping grooves for fixing and clamping with the bottom of the row support 14, realizing the horizontal positioning of the row support 14. The side support 13 is an L-shaped support perpendicular to the vertical support 11, and its two ends are welded to the outside wall of the vertical support 11.

[0039] Preferably, the row support 14 is a transversely arranged U-shaped steel frame, the bottom end of which is fixedly embedded in the clamping groove of the cross beam 12, and the end is connected with the fixed end of the sliding rail 21 through bolts. The interval unit 2 is composed of the sliding rail 21 and the row support 14 of the support unit 1, and its core function is to provide dynamic positioning space for the fixed unit 3. The sliding rail 21 is a long strip-shaped track, and its cross section is an inverted "T"-shaped notch structure, and the inside is provided with a smooth sliding surface, which forms a low friction fit with the sliding block 31. The bottom of the sliding rail 21 is provided with a plurality of positioning holes for fixing with the top end of the row support 14 through bolts, ensuring the vertical stability of the sliding rail 21 in the shaft.

[0040] Preferably, the fixed unit 3 is composed of a sliding block 31, a clamping table 32, a tightening member 33 and an enclosure 34, and its design goal is to realize the flexible fixation of the cable 4 and the protection of the cable 4 coating. The sliding block 31 is a moving part in the sliding rail 21, and its main body is composed of a clamping plate 311, a one-way roller 312 and a rotating member 313. The clamping plate 311 is a rectangular metal plate, and its two side edges are provided with protruding guide strips buckled with the inner wall of the sliding rail 21, and the bottom is matched with the sliding surface of the sliding rail 21 through the one-way roller 312. The one-way roller 312 is arranged in equal intervals on the upper and lower surfaces of the clamping plate 311, and its axis is nested in the rotating member 313, and the rotating member 313 is connected with the one-way roller 312 through the notch clamping structure, forming a transmission structure. The one-way roller 312 is provided with a ratchet inside, which makes the one-way roller 312 can only slide on one side, preventing it from sliding outward. The rotating member 313 is a hollow cylinder, and its axis is slidably connected with the avoiding circular groove 324 of the clamping table 32, allowing the sliding block 31 to move freely in the sliding rail 21 to adapt to the installation requirements of the cable. In addition, when the one-way roller 312 rolls along the inside of the sliding rail 21, the one-way roller 312 will drive the rotating member 313 to rotate, and after the rotating member 313 rotates, it will indirectly drive multiple sets of enclosures 34 to tighten, finally intensifying the enclosure of the cable 4.

[0041] The clamping table 32 is a flexible platform for clamping the cable 4. The mounting plate 321 is in a rectangular plate structure, and the end face of the mounting plate 321 extends a centering block 322, which is a semicircular structure protruding from the end of the mounting plate 321, and an arc-shaped groove is provided on the inner side of the centering block 322, which is used to guide the cable to the center position of the clamping table 32, and the cable surface is in contact with the elastic material such as rubber pad to avoid mechanical damage. The mounting plate 321 and the centering block 322 are in an integral structure, and a slot hole is provided on the inner side of the mounting plate 321, which is convenient for the shaft connection of the clamping table and the clamping plate 311 through the connecting bolt 323 and the clamping plate 311, and the clamping table is adjusted in angle with the clamping plate 311. The avoiding circular groove 324 is an annular groove at the shaft center of the mounting plate 321, and the inner diameter of the avoiding circular groove 324 matches the outer diameter of the rotating part 313, allowing the rotating part 313 to freely slide in the avoiding circular groove 324, thereby cooperating with the rotation adjustment function of the clamping table 32. The tightening member 33 is a rotating driving structure mounted on the inner side of the clamping table 32, which adjusts the clamping force of the clamping member 34 through the rotation of the screw knob itself, tightly fixes the cable in the non-slip pattern of the centering block 322, and avoids excessive clamping to cause the cable to deform. One end of the clamping member 34 is provided with an L-shaped lock at both ends of the end of the clamping table 32, and the other end is threadedly combined in the slot hole on the other side of the end of the clamping table 32.

[0042] Preferably, the cable 4 is flexibly fixed by the clamping table 32 of the fixing unit 3, and the outer surface is coated with a perfluorohexone coating layer 41. The perfluorohexone coating layer 41 uniformly covers the outer sheath of the cable 4 through a spraying process to form a continuous flame-retardant layer. The coating is in a transparent solid state at room temperature, adheres to the outer skin of the cable 4, and rapidly decomposes into gaseous perfluorohexone when exposed to high temperature to achieve fire extinguishing through heat absorption cooling and oxygen isolation. The thickness of the coating layer 41 is controlled by multi-layer spraying to ensure that it has sufficient fireproof performance and does not affect the flexibility of the cable. The cable 4 can adapt to the bending arrangement of the cable itself in the clamping table 32, and can be flexibly adjusted to the wiring demand of different floors in the shaft through the sliding adjustment of the sliding block 31.

[0043] The sliding block 31 is pushed into use along the sliding rail 21, the clamping table 32 is fixedly connected through the connecting bolt 323 at the shaft center thereof and is adjusted in angle with the same as the pivot to adapt to the change of the installation angle of the cable 4. The perfluorohexone coating layer 41 forms a fireproof barrier on the surface of the cable, and when the cable causes a fire due to overload or short circuit, the coating layer 41 rapidly decomposes the fire extinguishing agent to block the fire spreading path. The sliding block 31 can slide on the sliding rail 21 to allow the laying path of the cable 4 to be dynamically adjusted according to the actual demand. The cable 4 can be first tightly bound by the clamping member 34, and the one-way roller 312 in the sliding block 31 is further rolled to drive the rotation of the tightening member 33, thereby realizing the screwing of the clamping member 34 to the cable 4. The further locking function of the clamping member 34 ensures that the cable can still be stably clamped during frequent maintenance operations, reducing the frequency of manual intervention.

[0044] Referring toFigures 3-7 As an optional embodiment, in one embodiment provided in the present application, the confinement member 34 comprises a plurality of telescopic rods 341 arranged in a circumferential array at the end of the mounting plate 321, a flexible binding plate 342 fixed to one side of the telescopic rod 341, and a peg 343 arranged at one end of the flexible binding plate 342.

[0045] Further, the mounting plate 321 comprises a slot 3211 for fixing the peg 343, a slot hole 3212 for radially limiting the telescopic rod 341, and a ring groove 3213 for accommodating the tightening member 33.

[0046] Further, the tightening member 33 comprises a ring tooth 331 clamped on the inner side of the ring groove 3213, and a driving rod 332 engaged on the outer side of the ring tooth 331.

[0047] Further, the driving rod 332 comprises a driving wheel 3321 engaged with the ring tooth 331, and a rectangular block 3322 protruding at the end of the driving wheel 3321.

[0048] Further, the telescopic rod 341 comprises a screw cap 3411 radially clamped on the inner side of the slot hole 3212, a screw rod 3412 threadedly connected on the inner side of the screw cap 3411, and a rotating cap 3413 circumferentially limited on the inner side of the end of the screw rod 3412.

[0049] Further, the screw rod 3412 is provided with a clamping hole 51 consistent with the cross-sectional shape of the rectangular block 3322.

[0050] In the present embodiment, the structure of the confinement member 34 is further refined as a cooperative combination of the circumferential array of the telescopic rods 341, the flexible binding plate 342, and the peg 343. Specifically, the telescopic rod 341 is a metal rod body threadedly screwed in the slot hole 3212 and radially slidable. The flexible binding plate 342 is an arc-shaped elastic plate structure, with a rubber non-slip layer coated on the inner side surface, and two rope-shaped structures extending out at both sides, facilitating fixation at both ends of the clamping table 32 on both sides, so as to confine the cable 4 inside the centering block 322. One end of the flexible binding plate 342 is fixed to the end of the telescopic rod 341, forming a flexible clamping surface that can displace with the telescopic rod 341. The peg 343 is a T-shaped cylindrical metal rod, which is slidably embedded in the slot 3211 of the mounting plate 321, forming a mechanical lock structure to ensure the stability of the confinement member 34 in the locked state.

[0051] Preferably, the slot 3211 is located at the end of the mounting plate 321. Its cross-section is L-shaped, and its depth is adapted to the insertion length of the bolt block 343. The bottom of the slot is provided with anti-slip teeth to enhance the friction of the bolt block 343. The slot holes 3212 are hexagonal through-holes distributed along the width of the mounting plate 321. Their width matches the outer diameter of the telescopic rod 341, allowing the telescopic rod 341 to slide freely radially within the slot holes 3212. The annular groove 3213 is located in the center area of ​​the mounting plate 321. Its inner wall is embedded with an annular ring 331 with teeth on both the inside and outside. This facilitates the formation of a meshing transmission relationship with the drive rod 332 of the tightening member 33, while also forming a meshing transmission relationship with the gear in the middle of the rotating member 313. The driving mechanism of the tightening member 33 is composed of a ring tooth 331 and a driving rod 332. When the one-way roller 312 rolls along the inner side of the slide rail 21, the rotating member 313 is restricted by the one-way roller 312 and driven to rotate. The rotating member 313 drives the ring tooth 331 and the driving rod 332 engaged on the outside of the ring tooth 331 to rotate, thereby realizing the axial displacement of the telescopic rod 341.

[0052] The driving rod 332 includes a driving wheel 3321 and a rectangular block 3322, wherein the driving wheel 3321 is a gear structure, and the outer side is engaged with the ring gear 331; the rectangular block 3322 is a rigid protrusion, and its cross-sectional shape is completely matched with the clamping hole 51 of the screw 3412, and the rotational motion of the driving rod 332 is converted into axial displacement of the screw 3412 through plug-in cooperation.

[0053] Preferably, the nut 3411 is a hexagonal metal cap body with a hexagonal cross-section, and the inner thread matches the thread of the screw 3412, and the axial movement range of the screw 3412 is limited by screwing adjustment. The nut 3411 is fixedly embedded in the slot 3212 to achieve circumferential fixation of the nut 3411. The screw 3412 is a hollow cylinder, the outer thread is connected to the nut 3411, and a snap-in hole 51 matching the rectangular block 3322 is provided on the inner side. The rotation drive of the screw 3412 is achieved by inserting the rectangular block 3322. The rotating cap 3413 is an annular cover plate, and a convex rib matching the limit groove at the end of the screw 3412 is provided on the inner side. The circumferential limit is used to prevent the screw 3412 from loosening in the non-driven state. The movement of the screw 3412 is limited in displacement direction by the thread locking of the nut 3411.

[0054] The bolt block 343 is securely connected to the mounting plate 321 via the slot 3211. Even if the flexible binding plate 342 experiences elastic fatigue due to long-term use, the bolt block 343 maintains the basic fixed state of the cable 4 through its mechanical locking action, preventing the cable 4 from falling out due to vibration or external impact. In addition, the wavy raised pattern of the flexible binding plate 342 evenly distributes pressure during tightening, preventing localized stress concentration that could cause rupture of the cable 4 outer sheath.

[0055] When the cable 4 causes a fire due to short circuit or overload, the perfluorocyclohexanone coating 41 rapidly vaporizes to form a gaseous fire extinguishing agent, covering the clamping area between the flexible cable clamp 342 and the cable 4. The high elasticity of the flexible cable clamp 342 allows the fire extinguishing agent to freely penetrate the surface of the cable 4, while its wavy pattern can act as a diffusion guide channel for the fire extinguishing agent, accelerating the uniform distribution of gaseous perfluorocyclohexanone in the shaft.

[0056] When installing and fixing the cable 4, the slider 31 is pushed into use along the slide rail 21, the clamping table 32 is fixedly connected through the connecting bolt 323 at its axis, and the angle is adjusted with it as the pivot to adapt to the installation angle requirements of the cable 4. After the angle is adjusted, when the cable 4 needs to be tightened, the operator first embeds the bolt block 343 into the slot 3211 to clamp the cable 4; then rotates the screw rod 3412 to displace the screw rod 3412 along the slide rail 21, thereby tightening the flexible cable clamp 342.

[0057] When the slider 31 is slightly slid by external force, the one-way roller 312 rolls one-way to further rotate the tightening member 33, thereby rotating the ring teeth 331 and the driving rod 332 engaged outside the ring teeth 331, finally realizing the rotation of the rectangular block 3322 to drive the screw rod 3412 to rotate, which is transmitted to the screw rod 3412 through the clamping hole 51 of the screw rod 3412, so that the screw rod 3412 moves axially, and the flexible cable clamp 342 further adheres to the surface of the cable 4. When the flexible cable clamp 342 contacts the cable 4, the bolt block 343 is embedded in the slot 3211 and locked, completing the enclosure of the cable 4. At this time, the limiting convex rib of the rotating cap 3413 engages with the end of the screw rod 3412, without hindering the rotation of the screw rod 3412 itself.

[0058] During use, when the operator installs and fixes the cable 4, the slider 31 is first pushed into the target position along the slide rail 21. The clamping plate 311 of the slider 31 is in contact with the sliding surface of the inner wall of the slide rail 21 through the one-way roller 312, and the one-way ratchet structure of the one-way roller 312 ensures that the slider 31 can only slide in the preset direction, preventing accidental reverse displacement. After the slider 31 is in place, the clamping table 32 is circumferentially limitedly connected with the axis hole of the clamping plate 311 through the connecting bolt 323 at its axis, and the threaded end of the connecting bolt 323 is screwed into the center screw hole of the clamping plate 311, forming a rigid fixation. At this time, the operator can manually rotate the clamping table 32 with the connecting bolt 323 as the pivot to adjust the plane angle of the clamping table 32, so that it matches the layout direction of the cable 4. After adjustment, the operator embeds the bolt block 343 into the slot 3211 at the end of the mounting plate 321, and the flexible cable clamp 342 moves towards the cable 4, preliminarily completing the clamping of the cable 4.

[0059] When the slider 31 is slightly slid under the intervention of external force, the tightening member 33 is self-locked, the one-way roller 312 rolls one-way to further roll and drive the rotation of the tightening member 33, thereby driving the rotation of the ring teeth 331 and the driving rod 332 engaged outside the ring teeth 331, through the rotation of the rectangular block 3322 of the driving rod 332, the corner of the rectangular block 3322 is embedded in the clamping hole 51 of the screw rod 3412, and the rotation of the driving rod 332 is converted into the axial displacement of the screw rod 3412. The screw rod 3412 pushes the nut 3411 to slide along the inner side of the slot hole 3212 through the threaded connection, drives the telescopic rod 341 to extend outward, and the flexible binding plate 342 applies pressure to the surface of the cable 4, realizing flexible binding. In this process, the limiting convex rib of the rotating cap 3413 is clamped with the annular groove at the end of the screw rod 3412, allowing the screw rod 3412 to rotate freely but limiting its axial retreat, ensuring the one-way locking feature of the tightening operation.

[0060] In summary, through the setting of the one-way roller 312 and the rotating member 313, combined with the rotation adaptation of the avoiding circular groove 324 of the clamping table 32 and the connecting bolt 323, the flexible adjustment of the installation angle of the cable 4 and the automatic reinforcement function triggered by sliding are realized. The one-way sliding of the slider 31 along the slide rail 21 can drive the rotation of the rotating member 313, and then through the meshing of the ring teeth 331 and the driving rod 332, the shaking of the cable 4 is converted into the axial displacement of the confinement member 34, so that the flexible binding plate 342 is in real time. The surface of the cable 4 is adhered. Ensure that the confinement member 34 can still maintain stable locking after dynamic adjustment, significantly improve the redundant safety of cable 4 clamping. In addition, the coating process of perfluorohexanone coating 41 and the wave-shaped pattern of flexible binding plate 342 optimize the diffusion efficiency of fire extinguishing agent, so that the cable 4 can quickly form a gaseous protective barrier under the fire scene, blocking the fire spread path.

[0061] 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.
