Description

Technical Field

[0001] The present application relates to the field of cable technology, and in particular to a cable interlayer fire extinguishing device. Background Art

[0002] A cable mezzanine is a structural layer used to route cables entering instruments, control devices, panels, desks, and cabinets within control rooms and / or electronic equipment rooms. Control rooms or electrical rooms are often the lifeblood of the entire factory or enterprise, with numerous cables flowing in and out. Therefore, a cable mezzanine is typically installed beneath or above electrical equipment such as panels and cabinets within these rooms. Because cable mezzanines are located within walls or floors, they are rarely inspected by employees, making them difficult to detect as fire hazards. Furthermore, the cables are densely packed and their outer coverings are flammable. If a fire occurs within the mezzanine, it can spread rapidly. Therefore, fire prevention and fire suppression measures are essential for cable mezzanines.

[0003] In the prior art, there are some fire prevention and fire extinguishing devices for cable interlayers. For example, Patent No. CN205516092U discloses a fire prevention and fire extinguishing device for cable interlayers, comprising a fireproof board and a fire-blocking bag arranged on the surface of the fireproof board, an angle iron bracket is arranged on the periphery of the fireproof board, and the fireproof board is fixed to the wall surface through the angle iron bracket, a cable is arranged on one side of the fire-blocking bag, and the cable passes through the bottom of the cabinet, a cable-type differential temperature detector is arranged on the surface of the cable, a mounting buckle is arranged on the surface of the cable-type differential temperature detector, and the mounting buckle is slidably connected to the guide rail, a data interface is arranged on the side wall of the cable-type differential temperature detector, a fireproof pillow is arranged on the surface of the fireproof board, an ultra-fine dry powder fire extinguishing device is arranged on the surface of the wall, and a nozzle is arranged on the surface of the ultra-fine dry powder fire extinguishing device.

[0004] However, the existing cable interlayer fire prevention and extinguishing device wraps the entire cable interlayer and does not provide a corresponding structure to separate individual cables. Once a fire occurs, the fire spreads between adjacent cables and is difficult to control. Moreover, when the device is used to prevent and extinguish the fire in the cable interlayer, it is not possible to selectively move the fire extinguishing device to the fire area, and the entire cable interlayer can only be protected centrally. In this way, when a fire occurs, not only will the fire spread between adjacent cables, but the entire area will also burn, increasing the difficulty of fire extinguishing. At the same time, bundling the cables is not convenient for the inspection and maintenance of individual cables. Utility Model Content

[0005] The existing fire prevention and fire extinguishing devices of cable interlayers wrap the cable interlayer as a whole for fire prevention and fire extinguishing, which is not conducive to workers' daily inspection and replacement of cables. At the same time, when a fire occurs, the fire will quickly spread to other unburned cables, causing unnecessary losses. As more cables catch fire, the difficulty of fire fighting increases.

[0006] The present application provides a cable夹层fire extinguishing device. By arranging fireproof partitions in the cable夹层, the cables are separated, preventing the quickly spreading of the burning cables to the non-burning ones. Additionally, the device can move between cable夹层s, enabling targeted enclosure of the cable夹层 where a fire has occurred and reducing losses.

[0007] The present application provides a cable夹层fire extinguishing device, including a placement frame and two adjustment plates for adjusting the size of the front and rear openings of the placement frame. A vertically arranged fireproof partition for dividing the interior of the placement frame into multiple independent cable accommodation frames is provided in the placement frame, and the adjustment plates are movably connected to the placement frame;

[0008] Among them, the bottom of the placement frame is open for each cable to enter each cable accommodation frame through the bottom opening. And a plurality of connection ports for connecting the fire extinguishing device are provided on one of the adjustment plates, and the plurality of connection ports correspond to the plurality of cable accommodation frames one by one. The fire extinguishing device is used to extinguish the cables in the corresponding cable accommodation frames through the connection ports.

[0009] Furthermore, a bottom plate is movably connected to the bottom of the placement frame for closing the bottom opening of the placement frame.

[0010] Furthermore, one end of the bottom of the placement frame is connected to one end of the top of the bottom plate through a rotating shaft. A connection groove is provided at the middle position of the other end of the bottom of the placement frame, and a connecting rod that can be inserted into the connection groove is provided at the middle position of the other end of the top of the bottom plate. Limiting holes are opened on the outer wall of the connection groove and on the connecting rod.

[0011] Furthermore, "凵"-shaped slots are opened at both the front and rear openings of the placement frame, and the adjustment plates are movably arranged in the slots.

[0012] Furthermore, a plurality of limiting rings for limiting the adjustment plates at different heights are provided on the side walls of the placement frame near the front and rear openings, and a limiting rod matching the limiting rings is provided on one side of the adjustment plate.

[0013] Furthermore, an arc-shaped opening for clamping the cable is opened at the lower end of the adjustment plate.

[0014] Preferably, it further includes a plurality of smoke-temperature composite detectors arranged at intervals on the cable夹层. The plurality of smoke-temperature composite detectors are connected to a control device, and the control device is also connected to a fire alarm bell.

[0015] Compared with the existing technology, the beneficial effects of the present application are reflected in:

[0016] 1. This device separates the placement frame into multiple independent cable accommodating frames through fireproof partitions, and separates the cables. This slows down the spread of fire after the cable interlayer catches fire, protects the unburned cable interlayer, and reduces losses.

[0017] 2. Through the movable connection between the adjustment plate and the placement frame, the device can be used for cables of different specifications and thicknesses;

[0018] 3. Through the movable connection between the placement frame and the bottom plate, it can be applied to the layout of multi-layer cable mezzanine and single-layer cable mezzanine.

[0019] 4. The cable interlayer fire extinguishing device of the device can extinguish the fire at the fire site of the cable in a targeted manner. It does not need to wrap the entire cable interlayer, and it will not affect the technicians' routine maintenance work on the cable interlayer. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application are clearly and completely described below. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts also fall within the scope of protection of this application.

[0033] The inventors have found that in a specific application, the existing fire prevention and extinguishing device of the cable interlayer needs to completely surround the entire cable interlayer from the outside. In the event of a fire, the burning cable will ignite the unburned cables, increasing the loss.

[0034] Based on the problems existing in the prior art, the inventors have studied a cable interlayer fire extinguishing device. In specific applications, when a single cable is found to be on fire, the burning cable is first separated from the unburned cables to prevent the fire from spreading, and then the fire is extinguished, reducing losses.

[0035] See also Figures 1-9 The cable interlayer fire extinguishing device provided in this application includes a placement frame 1 and two adjustment plates 2 for adjusting the size of the front and rear openings of the placement frame 1. The placement frame 1 is provided with a vertically arranged fireproof partition 6 for dividing its interior into multiple independent cable accommodating frames 12. The adjustment plates 2 are movably connected to the placement frame 1;

[0036] Among them, the bottom opening of the placement frame 1 is used for each cable to enter each cable accommodating frame 12 through the bottom opening, and one of the adjustment plates 2 is provided with multiple connection ports 3 for connecting the fire extinguishing device, and the multiple connection ports 3 correspond one-to-one to the multiple cable accommodating frames 12. The fire extinguishing device is used to extinguish the cables in the corresponding cable accommodating frames 12 through the connection ports 3.

[0037] When a cable fire is detected, placement frame 1 is placed over the burning cable. Through the bottom opening of placement frame 1, each cable is placed into a cable containment frame 12 separated by fire partitions 6. This isolates the burning cable from other cables and prevents the fire from spreading laterally to nearby, unburned cables. Adjustment plates on the front and rear openings of placement frame 1 are moved downward until they fit over the cable, sealing the front and rear openings of placement frame 1. This seals the burning cable segment within cable containment frame 12 and prevents the burning cable segment from spreading to unburned cable segments within the same cable. A fire extinguishing device is connected to the corresponding connection port of cable containment frame 12 containing the burning cable. Fire extinguishing material is sprayed into cable containment frame 12 through the fire extinguishing device to extinguish the burning cable within the cable containment frame 12. This allows for more targeted fire extinguishing of the burning cable and reduces the use of fire extinguishing material.

[0038] In the present application, the fireproof partition 6 is configured to be a fireproof material, so that the fireproof partition 6 can not only divide the interior of the placement frame 1 into multiple independent cable accommodating frames 12, which is convenient for separating and placing the cables, but also has a fireproof function. When the cable catches fire, the fireproof partition 6 can better block the flames and provide better protection for the remaining cables.

[0039] In addition, the placement frame 1 and the adjustment plate 2 are both made of fireproof materials.

[0040] Furthermore, a bottom plate 14 movably connected to the bottom of the placement frame 1 is used to close the bottom opening of the placement frame 1 .

[0041] It should be noted that the installation of a bottom plate 14 at the bottom of the placement frame 1 enables the placement frame 1 to be used in structures with multiple cable layers. Since there are gaps between the cable layers, when the placement frame 1 needs to be installed in a cable mezzanine other than the bottom layer, fire below the upper layer cables can be prevented from igniting the lower layer cables. Therefore, the installation of the bottom plate 14 can be used to isolate the burning cables. Furthermore, the connection between the bottom plate 14 and the placement frame 1 facilitates the stability of the device during the fire extinguishing process.

[0042] The placement frame 1 is movably connected to the bottom plate 14 (e.g., by sliding, rotating, or hinged connection). The bottom plate 14 can either close or open the bottom opening of the placement frame 1. During use, the bottom opening of the placement frame 1 is opened by operating the bottom plate 14, and individual cables can be placed through the bottom opening of the placement frame 1 into the cable receiving frames 12 separated by the fire partitions 6. The bottom plate 14 is then operated to close the bottom opening of the placement frame 1.

[0043] In a possible implementation, one end of the bottom of the placement frame 1 is rotatably connected to one end of the top of the bottom plate 14 through a pin 13. At the middle position of the other end of the bottom of the placement frame 1, there is a connection groove 15. At the middle position of the other end of the top of the bottom plate 14, there is a connecting rod 16 that can be inserted into the connection groove 15. Limiting holes 17 are provided on the outer wall of the connection groove 15 and on the connecting rod 16.

[0044] When the connecting rod 16 is inserted into the connection groove 15, a threaded rod or a limit pin can be inserted into the limiting holes 17 in the connection groove 15 and the connecting rod 16 to improve the stability of the connection between the bottom plate 14 and the bottom of the placement frame 1.

[0045] During the specific use process, pull down the bottom plate 14, sleuth each cable receiving frame 12 of the placement frame 1 on each cable 21 in the cable interlayer to achieve cable isolation. Insert the connecting rod 16 on the bottom plate 14 into the connection groove 15 at the bottom of the placement frame 1. The limiting holes 17 on the connecting rod 16 are aligned with the limiting holes 17 on the outer wall of the connection groove 15. Use a threaded rod or a limit pin to insert into the limiting holes 17 to fix the connecting rod 16 in the connection groove 15, so as to stably place the cable in the placement frame 1.

[0046] In a possible implementation, "U"-shaped notch 5 is provided at both the front and rear openings of the placement frame 1, and the adjusting plate 2 is movably arranged in the notch 5.

[0047] The thickness of the notch 5 matches the thickness of the adjusting plate 2, ensuring that after the adjusting plate 2 is inserted into the notch 5, it can completely close the front and rear openings of the placement frame 1 and enclose the burning cable in the placement frame 1. Among them, the height of the scheduling plate 2 should be higher than the height of the notch 5.

[0048] In a possible implementation, a plurality of limiting rings 7 for limiting the adjusting plate 2 at different heights are provided on the side walls of the placement frame 1 near the front and rear openings, and a limiting rod 8 matching the limiting rings 7 is provided on one side of the adjusting plate 2.

[0049] A limiting rod 8 matching the limiting rings 7 is provided on the outer side of the adjusting plate 2. After the placement frame 1 and the adjusting plate 2 are placed on the cable, according to the thickness of different cables, the limiting rod 8 on the adjusting plate 2 is matched with the limiting rings 7 at different positions on the outside of the placement frame 1, so as to adjust the position of the adjusting plate 2 and limit the adjusted position of the adjusting plate 2, ensuring the stability of the adjusting plate 2 during the operation of the device.

[0050] In addition, the limiting rod 8 includes a connecting section 9 and a limiting section 10. The connecting section 9 is connected to the limiting section 10 through a rotating shaft 11. The connecting section 9 is connected to the outer side of the adjusting plate 2, and the limiting section 10 cooperates with the limiting ring 7.

[0051] Furthermore, an arc-shaped opening 4 for clamping a cable is formed at the lower end of the adjustment plate 2 .

[0052] The opening at the lower end of the adjusting plate 2 is set to be arc-shaped because the cable is cylindrical. The arc-shaped structure can fit more closely to the surface of the cable, avoiding a large gap between the adjusting plate 2 and the cable. When the cable catches fire, flames will spray out from the gap, igniting nearby cables or causing harm to workers.

[0053] Furthermore, it also includes a plurality of smoke and temperature composite detectors 18 spaced apart on the cable interlayer. The plurality of smoke and temperature composite detectors 18 are connected to a control device 20 , and the control device is also connected to the fire alarm 19 .

[0054] During specific use, the smoke and temperature composite detector 18 corresponding to the fire section transmits the fire information of the detected cable interlayer to the control device 20 (for example, the control device 20 can be a mobile phone, computer, etc.), and the control device 20 transmits the fire information to the fire alarm 19. The fire alarm 19 sounds an alarm. After hearing the alarm, the staff obtains the specific location of the cable fire from the position of the smoke and temperature composite detector 18 reported by the control device 20 according to the location of the cable fire, and uses the cable interlayer fire extinguishing device of this application corresponding to the fire location of the cable to extinguish the cable.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
