Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of fire safety, specifically to a cabinet fire extinguishing component with a built-in quick-release function. Background Technology
[0002] Fire safety is of paramount importance because fires can cause enormous damage to life, property, and the environment. Fires can spread rapidly, leading to casualties. Many people may lose their lives due to smoke inhalation, burns, or accidents during escape. At the same time, fires can cause devastating damage to buildings, equipment, and various materials, leaving no place unscathed, whether it be residential, commercial, or industrial facilities. From an environmental perspective, fires release large amounts of harmful gases and particulate matter, polluting the air and affecting the ecological balance.
[0003] In the process of developing this utility model, the inventors discovered the following problems with the existing technology: 1. When fire-fighting components malfunction, they need to be repaired or replaced as soon as possible to ensure the normal operation of the fire-fighting system. If they are fixed with screws and are inconvenient to disassemble, maintenance personnel need to spend a lot of time removing the screws, which is very disadvantageous in emergency situations. For example, when a smoke detector malfunctions and a fire may occur at any time, every extra minute spent removing the screws increases the danger; 2. In the early stages of a fire, the fire is usually small, which is the best time to extinguish it. However, many existing fire-fighting components, without manual operation or automatic detection and extinguishing functions, cannot react to the fire in time, causing electrical damage inside the cabinet and creating greater danger. Utility Model Content
[0004] The purpose of this utility model is to provide a cabinet fire extinguishing component with a self-contained quick-release function, in order to solve the problem mentioned in the background art that in the early stage of a fire, when the fire is usually small and the best time to extinguish it is, prolonged extinguishing time can easily lead to greater fire damage. To achieve the above objective, this utility model provides the following technical solution: a cabinet fire extinguishing component with a self-contained quick-release function, including a cabinet body, a control panel mounted on the top of the cabinet body by screws, a fire extinguisher bottle body located on one side of the cabinet body, a smoke detector mounted inside the cabinet body by screws, and a combustible gas detector located on one side of the smoke detector;
[0005] A first slide rail is installed at the front of the cabinet by screws. A slide rod is installed inside the first slide rail by screws. A movable plate is attached to the outer wall of the slide rod. A filter screen is installed in the slot inside the cabinet by screws. A threaded screw is threaded to the nut inside the movable plate. A second slide rail is installed above the threaded screw by screws. The housing of a servo motor is installed above the second slide rail by screws.
[0006] A nozzle is installed on the top of the fire extinguisher bottle by screws. A second limiting ring is attached to the outer wall of the fire extinguisher bottle. A connecting plate is attached to the bottom of the fire extinguisher bottle. A first limiting ring is magnetically attached to the bottom of the connecting plate. A support plate is welded to the bottom of the first limiting ring.
[0007] In a further preferred embodiment, the threaded screw is configured to rotate via a servo motor, and a nut is provided at one end of the moving plate. The internal structural dimensions of the nut are consistent with the external threads of the threaded screw, and the internal structural dimensions of the moving plate are consistent with the external structural dimensions of the slide bar.
[0008] More preferably, the movable plate forms a vertical sliding structure through a threaded screw and a slide rod.
[0009] More preferably, the fire extinguisher bottle is filled with carbon dioxide, and the nozzle is made of a temperature-sensitive glass bulb.
[0010] More preferably, the external structural dimensions of the fire extinguisher bottle body are consistent with the internal structural dimensions of the second limiting ring, and the second limiting ring is made of TPE plastic.
[0011] More preferably, the lower external structural dimensions of the fire extinguisher bottle body are consistent with the upper internal structural dimensions of the connecting plate.
[0012] More preferably, the external structural dimensions of the four corner inserts of the connecting plate are consistent with the internal structural dimensions of the four upper corner first limiting rings of the support plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] In this invention, the second limiting ring is manually pried open, and the magnetic suction piece allows the insert rod below the connecting plate to easily detach from the support plate. The fire extinguisher bottle and the base of the connecting plate can then be easily pulled upwards. The silicone pad inside the base ensures that the extinguisher will not fall off during normal use, while also not hindering disassembly. This design greatly simplifies the disassembly process of the fire extinguisher, eliminating the need for maintenance personnel to spend a significant amount of time removing screws. When fire-fighting components malfunction, replacement can be completed quickly, reducing the risk of fire system failure due to maintenance delays and effectively ensuring the normal operation of the fire-fighting system in emergency situations.
[0015] In this invention, a smoke detector and a combustible gas detector are installed inside the cabinet. This allows for real-time monitoring of the smoke and combustible gas concentrations in the surrounding environment. When a set threshold is reached, the detector quickly sends a signal to the control panel. The control panel analyzes and processes the signal through a built-in program to determine whether the danger threshold has been exceeded. Once exceeded, the control program is activated. This automatic detection mechanism requires no manual intervention and can detect potential dangers in the early stages of a fire or even before the fire occurs. Compared to traditional fire-fighting components that require manual operation or lack automatic detection functions, this invention can react immediately, greatly shortening the time difference between the occurrence of a fire and the implementation of countermeasures, and effectively reducing the losses caused by the fire.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a cabinet fire extinguishing component with a quick-release function, including a cabinet body 1, a control panel 3 installed on the top of the cabinet body 1 by screws, a fire extinguisher bottle body 2 on one side of the cabinet body 1, a smoke alarm 4 installed inside the cabinet body 1 by screws, and a combustible gas detector 5 on one side of the smoke alarm 4.
[0023] A first slide rail 101 is installed at the front of the cabinet 1 by screws. A slide rod 102 is installed inside the first slide rail 101 by screws. A movable plate 103 is attached to the outer wall of the slide rod 102. A filter screen 107 is installed in the internal slot of the cabinet 1 by screws. A threaded screw rod 106 is threadedly connected to the nut inside the movable plate 103. A second slide rail 105 is installed above the threaded screw rod 106 by screws. The housing of a servo motor 104 is installed above the second slide rail 105 by screws.
[0024] A nozzle 203 is installed on the top of the fire extinguisher bottle body 2 by screws. A second limiting ring 201 is attached to the outer wall of the fire extinguisher bottle body 2. A connecting plate 202 is attached to the bottom of the fire extinguisher bottle body 2. A first limiting ring 204 is magnetically attached to the bottom of the connecting plate 202. A support plate 205 is welded to the bottom of the first limiting ring 204.
[0025] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the threaded screw 106 forms a rotating structure through the servo motor 104, and one end of the moving plate 103 is provided with a nut. The internal structural dimensions of the nut are consistent with the external threads of the threaded screw 106, and the internal structural dimensions of the moving plate 103 are consistent with the external structural dimensions of the slide rod 102. The precise thread matching ensures that the rotational power of the servo motor 104 can be efficiently and stably converted into the linear motion of the moving plate 103, avoiding jamming and loss in power transmission, and ensuring that the fire extinguishing components can respond quickly at critical moments. The matching dimensions of the moving plate 103 and the slide rod 102 provide stable guidance, preventing the moving plate 103 from deviating or shaking during movement, so that the subsequent driven components such as the support plate 205 and the fire extinguisher bottle body 2 can be accurately positioned, effectively improving the accuracy of fire extinguishing operations.
[0026] In this embodiment, as Figure 3 As shown, the movable plate 103 forms a vertical sliding structure with the screw rod 106 and the slide rod 102. The precision of the screw drive and the stability of the slide rod 102 guide ensure that the fire extinguisher components can quickly and smoothly reach the vicinity of the fire source in the complex environment of the cabinet 1. Whether dealing with small initial flames or slightly larger fires, the fire extinguishing force can be quickly deployed, greatly improving the fire extinguishing efficiency.
[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 4As shown, the fire extinguisher cylinder 2 is filled with carbon dioxide, and the nozzle 203 is made of a temperature-sensitive glass bulb. Carbon dioxide extinguishing agent has advantages such as being clean, non-polluting, and non-conductive, making it particularly suitable for fire extinguishing scenarios around electrical equipment and precision instruments, thus avoiding secondary damage. The use of the temperature-sensitive glass bulb gives the nozzle 203 the intelligent characteristic of automatically sensing the ambient temperature and triggering extinguishing. Once the ambient temperature rises to the melting point of the glass bulb, the extinguishing agent spray channel is immediately opened without human intervention, allowing for early fire suppression and effectively curbing the spread of fire.
[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the external structural dimensions of the fire extinguisher bottle body 2 are consistent with the internal structural dimensions of the second limiting ring 201, and the second limiting ring 201 is made of TPE plastic. Due to the size matching between the fire extinguisher bottle body 2 and the second limiting ring 201 and the material characteristics of the second limiting ring 201, under normal conditions, the second limiting ring 201 plays a role in fixing and limiting the fire extinguisher bottle body 2. When it is necessary to replace the fire extinguisher, the size matching between the two ensures smooth disassembly.
[0029] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the lower external structural dimensions of the fire extinguisher cylinder body 2 are consistent with the upper internal structural dimensions of the connecting plate 202; the fire extinguisher cylinder body 2 is securely connected to the connecting plate 202. Whether the device is in a static standby state or when the moving plate 103 drives the components to move urgently after a fire is triggered, the fire extinguisher cylinder body 2 will not easily detach from the connecting plate 202, ensuring the continuity of the fire extinguishing process, preventing fire extinguishing failure due to cylinder detachment, and effectively ensuring the reliable execution of the fire extinguishing function.
[0030] In this embodiment, as Figure 4 As shown, the external structural dimensions of the four corner inserts of the connecting plate 202 are consistent with the internal structural dimensions of the four upper corner first limiting rings 204 of the support plate 205. The connecting plate 202 can be stably mounted on the support plate 205. Under the influence of minor daily disturbances and severe vibrations and impacts during fire emergencies, the inserts and the first limiting rings 204 are tightly connected without loosening or misalignment, ensuring the integrity and reliability of the entire fire extinguishing assembly from the support structure to the fire extinguisher cylinder 2. This lays a solid foundation for rapid and efficient fire extinguishing. At the same time, this precise adaptation design also facilitates the quick disassembly and replacement of parts. Maintenance personnel can easily replace parts by simply operating according to the corresponding dimensions, improving maintenance efficiency.
[0031] The method of use and advantages of this utility model: The cabinet fire extinguishing component with built-in quick-release function works as follows:
[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, first manually pry open the second limiting ring 201 on one side, and pull out the fire extinguisher bottle body 2 and connecting plate 202 upwards. The insert rod below the connecting plate 202 has a magnetic detachment piece to facilitate separation from the support plate 205. After removal, pull the fire extinguisher bottle body 2 upwards to remove the base of the connecting plate 202. A silicone pad is provided inside the base to prevent it from falling off, facilitating disassembly and replacement of the fire extinguisher. The smoke alarm 4 is installed inside the cabinet 1. When the smoke concentration in the surrounding environment reaches a certain threshold, the smoke alarm 4 will be triggered. It typically uses optical principles or ion sensing principles to detect smoke. Smoke detector 4 is installed inside cabinet 1. When the smoke concentration in the surrounding environment reaches a certain threshold, smoke detector 4 will be triggered. It usually uses optical or ion sensing principles to detect smoke. Combustible gas detector 5 is also installed inside cabinet 1 to detect the concentration of combustible gases in the air. It can detect combustible gases such as methane and propane. When smoke detector 4 or combustible gas detector 5 detects an anomaly and sends a signal, the signal will be transmitted to control panel 3. Control panel 3 may contain components such as microprocessors and signal processing circuits. After receiving the signal, it will analyze and process the signal. For example, it will determine whether the signal exceeds a preset danger threshold through a built-in program. If it exceeds the threshold, control panel 3 will start the corresponding control program. Control panel 3 may have indicator lights to display the alarm status, such as a red indicator light to indicate a fire hazard. At the same time, control panel 3 will control servo motor 104. It controls the operation of servo motor 104 by sending electrical signals to servo motor 104. After receiving the signal, servo motor 104 will start rotating according to the instructions of control panel 3. Since the threaded screw 106 forms a rotating structure through servo motor 104, The rotation of the servo motor 104 will drive the threaded screw 106 to rotate. One end of the moving plate 103 is provided with a nut that matches the threaded screw 106. The moving plate 103 also cooperates with the slide rod 102. Under the rotation of the threaded screw 106 and the guiding action of the slide rod 102, the moving plate 103 will slide vertically, so that the moving plate 103 will drive the support plate 205, the fire extinguisher bottle body 2 and the nozzle 203 to move vertically in sequence. If the melting point of the nozzle 203 exceeds the limit, the internal fire extinguishing material can be automatically sprayed out to facilitate fire extinguishing. The nozzle 203 is aimed at the filter screen 107 to spray the inside of the cabinet 1.
