Description

Technical Field

[0001] This utility model relates to the field of fire safety technology, and in particular to a fire monitoring cabinet. Background Technology

[0002] In modern industrial and building facilities, various electrical equipment (such as power distribution devices, control modules, servers, and communication equipment) are typically installed centrally inside cabinets for unified management and protection. While this centralized deployment method facilitates maintenance and saves space, it also brings specific safety hazards: the cabinet space is relatively enclosed, with dense equipment, numerous cables, and high heat generation. Once an electrical short circuit, equipment overload, or poor contact occurs, it can easily lead to localized high temperatures or even fires. Moreover, fires can spread rapidly in confined spaces, with serious consequences.

[0003] However, existing products mostly rely on a single sensor (such as temperature or smoke alone) for judgment. In cabinets with dense electrical equipment, this single-factor monitoring method has a very high risk of false alarms. For example, in dusty industrial environments, smoke sensors alone may frequently trigger false alarms due to dust interference; and in areas near heat sources or direct sunlight, temperature sensors alone may also trigger alarms due to temperature increases for reasons other than fire (such as equipment overload heat dissipation or ambient temperature fluctuations). False alarms not only interfere with normal work, but may also lead to a sense of desensitization to alarms in the long run, resulting in delays in response when a real fire occurs.

[0004] Furthermore, the internal sensors of existing products are usually installed in a fixed manner, which makes it difficult to adapt to monitoring when monitoring electrical cabinets with different structures or equipment layouts. This results in a significant reduction in monitoring effectiveness and often requires reinstallation and setup, making operation extremely inconvenient and failing to meet the needs of flexible deployment and subsequent maintenance. Utility Model Content

[0005] The main purpose of this utility model is to propose a fire monitoring cabinet that aims to improve adaptability and alarm accuracy.

[0006] To achieve the above objectives, the fire monitoring cabinet proposed in this utility model includes:

[0007] The cabinet has a guide rail on the top inner side, and the brightness monitor is slidably connected to the guide rail;

[0008] The cabinet sidewall is provided with a connecting strip that extends along the height of the cabinet. The connecting strip is provided with multiple connecting slots spaced apart. The temperature monitor is fixed at different heights inside the cabinet by connecting to different connecting slots.

[0009] The cabinet door has a magnetic component embedded in its inner wall, and a switch monitor is provided on the side wall of the cabinet to monitor the opening and closing of the cabinet door.

[0010] An alarm is installed on the outer wall of the cabinet, and the alarm is electrically connected to the brightness monitor, the temperature monitor, and the switch monitor.

[0011] In one embodiment, the guide rail extends along the opening direction of the cabinet, and the brightness monitor is slid to move the brightness monitor away from or towards the cabinet door.

[0012] In one embodiment, the brightness monitor includes a connecting plate that abuts against one side of the guide rail near the top of the cabinet, and the brightness monitor is slidably connected to the guide rail via the connecting plate.

[0013] In one embodiment, the guide rail has an insertion interface on the side near the cabinet door. The cross-sectional shape of the insertion interface is adapted to the connecting plate, and the connecting plate is inserted into the guide rail through the insertion interface.

[0014] In one embodiment, the brightness monitor further includes a mounting block, the connecting plate is fixedly connected to the mounting block, and a mounting groove is formed in the monitoring surface of the mounting block away from the connecting plate, the mounting groove being used to mount a brightness sensor;

[0015] The mounting slot is equipped with a dustproof glass at its opening.

[0016] In one embodiment, there are two brightness monitors, and the two brightness monitors are respectively located on opposite sides of the guide rail along its length.

[0017] The monitoring surfaces of the two brightness monitors are both inclined and face the center of the cabinet interior.

[0018] In one embodiment, the temperature monitor includes a first clamping plate, a second clamping plate, and a first connector. The first clamping plate and the second clamping plate are located on opposite sides of the connecting strip, and the first connector passes through the first clamping plate, the connecting groove, and the second clamping plate in sequence. The first clamping plate and the second clamping plate are connected by the first connector to clamp the connecting strip.

[0019] In one embodiment, the first clamping plate is provided with an adjustment plate, the extension direction of which is consistent with the opening direction of the cabinet;

[0020] The temperature monitor also includes a mounting plate, on which a temperature sensor is mounted. The mounting plate is slidably connected to the adjustment plate to change the position of the temperature sensor within the cabinet.

[0021] In one embodiment, the adjustment plate includes support bars located on opposite sides of the mounting slide plate, and the mounting slide plate is slidably inserted between the two support bars.

[0022] In one embodiment, the mounting slide plate has positioning grooves on both sides that are adapted to the two support bars, and the support bars are located in the positioning grooves and abut against the inner wall of the positioning grooves;

[0023] The mounting plate also includes a second connector. The support bar has a groove. The second connector passes through the groove and the sidewalls of the positioning grooves on opposite sides of the groove. The second connector is adjusted to adjust the friction between the positioning grooves and the support bar.

[0024] This utility model's technical solution employs a brightness monitor, a temperature monitor, and a switch monitor to form a three-factor judgment mechanism. The alarm is triggered only when both temperature and brightness—two key fire characteristic parameters—simultaneously reach the danger threshold and the switch monitor detects the cabinet door is closed. This reduces false alarms caused by a single environmental factor and ensures that no personnel are operating the cabinet at this time. The guide rail allows the brightness monitor to move within the plane of the top of the cabinet, and the temperature monitor's height inside the cabinet is adjustable via the connecting strip and connecting groove. Users can precisely align the brightness and temperature monitors with the areas requiring focused monitoring based on the actual hotspot distribution or ignition points, rather than being fixed in a potentially ineffective position, thus improving applicability and monitoring effectiveness.

[0038] Furthermore, the internal sensors of existing products are usually installed in a fixed manner, which makes it difficult to adapt to monitoring when monitoring electrical cabinets with different structures or equipment layouts. This results in a significant reduction in monitoring effectiveness and often requires reinstallation and setup, making operation extremely inconvenient and failing to meet the needs of flexible deployment and subsequent maintenance.

[0039] This utility model proposes a fire monitoring cabinet 100.

[0040] Please see Figures 1 to 4 In one embodiment of this utility model, the fire monitoring cabinet 100 includes:

[0041] Cabinet 11, with a guide rail 111 on the top inner side of the cabinet 11, and the brightness monitor 2 is slidably connected to the guide rail 111;

[0042] The cabinet 11 has a connecting strip 112 on its side wall. The connecting strip 112 extends along the height of the cabinet 11. The connecting strip 112 is provided with a plurality of connecting slots 113 spaced apart. The temperature monitor 3 is fixed at different heights inside the cabinet 11 by connecting to different connecting slots 113.

[0043] Cabinet door 12, the inner wall of which is embedded with a magnetic element 5, and the side wall of the cabinet body 11 is provided with a switch monitor 4 to monitor the opening and closing of the cabinet door 12.

[0044] Alarm 13 is located on the outer wall of the cabinet 11, and is electrically connected to the brightness monitor 2, the temperature monitor 3 and the switch monitor 4.

[0045] It is understood that the top of the cabinet 11 refers to the side of the cabinet 11 that is away from the ground when the cabinet 11 is placed on the ground. The cabinet 11 has an opening on its side, and the cabinet door 12 is provided at the opening. The top of the cabinet 11 is defined as the upper side, and the opening of the cabinet 11 is facing forward.

[0046] It should be noted that the switch monitor 4 includes a Hall sensor. The opening and closing of the cabinet door 12 is identified by the Hall sensor and the magnetic component 5. When the cabinet door 12 is closed, the magnetic component 5 is close to the Hall sensor. When the cabinet door 12 is open, the magnetic component 5 is away from the Hall sensor. The switch state of the cabinet door 12 is determined by sensing the change in the magnetic field through the Hall sensor.

[0047] It should be noted that in some embodiments, the number of cabinet doors 12 is one, while in other embodiments, the number of cabinet doors 12 is two. It can be understood that the number of switch monitors 4 corresponds to the number of cabinet doors 12.

[0048] It should be noted that the fire monitoring cabinet 100 also includes a processor, which is electrically connected to the alarm 13, the brightness monitor 2, the temperature monitor 3 and the switch monitor 4. The processor processes the monitored information and controls the alarm 13 to sound an alarm.

[0049] The technical solution of this utility model uses a brightness monitor 2, a temperature monitor 3, and a switch monitor 4 to form a three-factor judgment mechanism. When the two key fire characteristic parameters, temperature and brightness, simultaneously reach the danger threshold and the switch monitor 4 detects that the cabinet door 12 is closed, the alarm 13 is triggered. This reduces false alarms caused by a single environmental factor and ensures that no personnel are operating the cabinet 11 at this time. The brightness monitor 2 can move within the plane at the top of the cabinet 11 through the guide rail 111, and the temperature monitor 3 can be adjusted in height inside the cabinet 11 through the connection of the connecting strip 112 and the connecting groove 113. Users can accurately align the brightness monitor 2 and the temperature monitor 3 with the areas that need to be monitored according to the actual hot spot distribution or easy ignition points, rather than being fixed in a position that may not be effective, thus improving applicability and detection effectiveness.

[0050] It is understandable that when the cabinet door 12 is opened, it usually means that there are operators nearby. If there is an abnormality inside the cabinet 11 at this time, the operator can directly perceive it and there is no need to sound an alarm. Furthermore, the opening of the cabinet door 12 will increase the brightness inside the cabinet 11. If there is no indication of the high temperature at this time due to the opening and closing of the cabinet door 12, misjudgment is likely to occur.

[0051] Secondly, electrical equipment may generate electric sparks during operation. If only the brightness is measured, the electric sparks may be mistaken for open flames.

[0052] Furthermore, the alarm is only triggered when the temperature monitor 3 detects a sudden change in temperature, in order to prevent false alarms.

[0053] Optionally, the guide rail 111 extends along the opening direction of the cabinet 11, and the brightness monitor 2 is slid to move away from or closer to the cabinet door 12.

[0054] It is understandable that the internal equipment layout varies greatly not only in height and width, but also in depth, where critical equipment may exist, such as power supplies installed at the rear, cable bundles deep inside, or areas with poor heat dissipation, such as rear corners. Fixed sensors may not be able to effectively monitor these areas due to distance or obstruction. By moving the brightness monitor 2 closer to or further away from the cabinet door 12, the observation angle and field of view of the brightness monitor 2 over the cabinet space can be changed, thereby adapting to different scenarios.

[0055] Optionally, the brightness monitor 2 includes a connecting plate 21, which abuts against one side of the guide rail 111 near the top of the cabinet 11, and the brightness monitor 2 is slidably connected to the guide rail 111 through the connecting plate 21.

[0056] It is understood that the connecting plate 21 abuts against the top plane of the guide rail 111 over a large area, providing a stable and flat support base for the brightness monitor 2. Furthermore, without external force, the friction between the connecting plate 21 and the plane of the guide rail 111 makes it difficult for them to shift, thus ensuring the stability of the position of the brightness monitor 2. When the position needs to be changed, it can be changed manually.

[0057] like Figure 3 As shown, optionally, the guide rail 111 has an insertion interface 1111 on the side near the cabinet door 12. The cross-sectional shape of the insertion interface 1111 is adapted to the connecting plate 21, and the connecting plate 21 is inserted into the guide rail 111 through the insertion interface 1111.

[0058] Understandably, the operator only needs to align the connecting plate 21 with the plug interface 1111 and push it in horizontally to complete the installation. No tools are required, which simplifies the installation process and facilitates subsequent maintenance and replacement.

[0059] It should be noted that the guide rail 111 is arched and connected to the inner top wall of the cabinet 11. The connecting wires between electrical devices can pass through the gap between the guide rail 111 and the cabinet 11, so as to avoid the guide rail 111 affecting the installation of the equipment.

[0060] like Figure 4 As shown, optionally, the brightness monitor 2 further includes a mounting block 22, the connecting plate 21 is fixedly connected to the mounting block 22, and the monitoring surface of the mounting block 22 away from the connecting plate 21 is recessed to form a mounting groove 221, which is used to mount the brightness sensor 24.

[0061] The mounting groove 221 is provided with a dustproof glass 23 at its opening.

[0062] It is understood that the brightness sensor 24 is embedded in the mounting block 22 through the mounting slot 221 to form an independent module. If the sensor fails or needs to be upgraded, the dustproof glass 23 of the mounting slot 221 can be opened to directly replace the sensor module without disassembling the entire monitor or rewiring.

[0063] Furthermore, the opening of the mounting groove 221 faces downwards, making it difficult for dust to accumulate at the dustproof glass 23, thus ensuring the accuracy of the brightness sensor 24. The dustproof glass 23 also prevents dust from entering the mounting groove 221 and affecting the normal operation of the brightness sensor 24.

[0064] In some embodiments, the mounting groove 221 has a mounting opening 222 on its side, and the dustproof glass 23 is inserted through the mounting opening 222 to cover the mounting groove 221, which facilitates installation and maintenance.

[0065] Optionally, there are two brightness monitors 2, and the two brightness monitors 2 are respectively located on opposite sides of the guide rail 111 along the length direction;

[0066] The monitoring surfaces of the two brightness monitors 2 are both inclined and face the center of the cabinet 11.

[0067] like Figure 3As shown, it can be understood that by using the two brightness detectors located on the front and rear sides of the guide rail 111, the blind spots in the monitoring of the cabinet space are reduced and the effective monitoring coverage is improved. For example, when the brightness detector is located on the front top of the cabinet 11, if an open flame occurs on the rear bottom of the cabinet 11, it may not be detected immediately due to the obstruction of the equipment inside the cabinet 11. By symmetrically arranging the two brightness detectors 2, the detection area is increased and the blind spots in the monitoring are reduced.

[0068] Furthermore, the monitoring surfaces of both brightness monitors 2 are tilted towards the center of the cabinet 11, forming an intersecting viewing angle, which further reduces monitoring blind spots.

[0069] Optionally, the temperature monitor 3 includes a first clamping plate 31, a second clamping plate 32, and a first connector 33. The first clamping plate 31 and the second clamping plate 32 are respectively located on opposite sides of the connecting strip 112. The first connector 33 passes through the first clamping plate 31, the connecting groove 113, and the second clamping plate 32 in sequence. The first clamping plate 31 and the second clamping plate 32 are connected by the first connector 33 to clamp the connecting strip 112.

[0070] like Figure 2 As shown, it can be understood that the first clamping plate 31 and the second clamping plate 32 are connected by the first connector 33, and the first clamping plate 31 and the second clamping plate 32 are brought closer or further apart by adjusting the first connector 33, thereby achieving the clamping or release of the connecting strip 112.

[0071] The first clamping plate 31 and the second clamping plate 32 generate sufficient pressure to fix the temperature monitor 3 to the connecting strip 112. The first connecting member 33 is located in the connecting groove 113. If horizontal movement occurs, the first connecting member 33 will abut against the connecting groove 113 to prevent the temperature monitor 3 from moving and ensure stability. The temperature monitor 3 can be adjusted in height by connecting to the connecting groove 113 at different heights.

[0072] Optionally, the first connector 33 includes a bolt and a nut, wherein the bolt may be a wing bolt to facilitate rotation.

[0073] Optionally, there are two first connectors 33, located on the upper and lower sides of the first clamping plate 31 respectively, to prevent the first clamping plate 31 and the second clamping plate 32 from rotating.

[0074] In some embodiments, the inner walls of the first clamping plate 31 and the second clamping plate 32 are provided with serrated anti-slip surfaces to improve the friction with the connecting strip 112.

[0075] Optionally, the first clamping plate 31 is provided with an adjusting plate 311, the extending direction of the adjusting plate 311 being consistent with the opening direction of the cabinet 11;

[0076] The temperature monitor 3 also includes a mounting plate 34, on which a temperature sensor 341 is mounted. The mounting plate 34 is slidably connected to the adjustment plate 311 to change the position of the temperature sensor 341 within the cabinet 11.

[0077] like Figure 2 As shown, it can be understood that the installation slide plate 34 and the adjustment plate 311 are used to adjust the horizontal front and back position of the temperature sensor 341 in the cabinet 11. With the connecting strip 112, the spatial position of the temperature sensor 341 can be adjusted to adapt to different scenarios. The temperature sensor 341 can be set to correspond with the ignition point, thereby improving adaptability and detection sensitivity.

[0078] It is understood that the connecting strip 112 extends along the height direction of the cabinet 11, while the extension direction of the adjusting plate 311 is consistent with the opening direction of the cabinet 11, that is, the extension direction of the adjusting plate 311 is perpendicular to the extension direction of the connecting strip 112.

[0079] Optionally, the adjustment plate 311 includes support bars 3111 located on opposite sides of the mounting plate 34, and the mounting plate 34 is slidably inserted between the two support bars 3111.

[0080] It is understood that the temperature sensor 341 is adjusted in the front-back direction by means of the two support bars 3111.

[0081] In some embodiments, the mounting plate 34 can be directly inserted from the support bar 3111 near the cabinet door 12 without the need for other tools, thus improving installation and maintenance efficiency.

[0082] Optionally, the mounting slide plate 34 is provided with positioning grooves 342 on both sides that are adapted to the two support bars 3111, and the support bars 3111 are located in the positioning grooves 342 and abut against the inner wall of the positioning grooves 342;

[0083] The mounting plate 34 also includes a second connector 343. The support bar 3111 has a groove 3112. The second connector 343 passes through the groove 3112 and the sidewalls of the positioning grooves 342 on opposite sides of the groove 3112. The second connector 343 is adjusted to adjust the friction between the positioning grooves 342 and the support bar 3111.

[0084] It should be noted that the slide groove 3112 is adapted to the second connector 343. When the mounting slide plate 34 moves, the second connector 343 moves within the slide groove 3112. Furthermore, the positioning groove 342 abuts against the support bar 3111. It can be understood that the positioning groove 342 partially surrounds the support bar 3111, enabling the support bar 3111 to provide stable support for the mounting slide plate 34.

[0085] Optionally, the second connector 343 includes a bolt and a nut, the bolt being a wing bolt to facilitate rotation. By adjusting the second connector 343, for example by rotating the nut, the friction between the positioning groove 342 and the support bar 3111 is adjusted to prevent the mounting slide plate 34 from moving easily in the front-back direction.

[0086] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
