Description

Technical Field

[0001] This invention relates to the field of fire-fighting equipment technology, specifically to a fire extinguisher box with automatic opening and closing and fire early warning functions. Background Technology

[0002] Fire extinguisher boxes are special containers for storing portable fire extinguishers and are widely used in key fire protection areas such as public places, office buildings, industrial plants, and residential buildings.

[0003] Traditional fire extinguisher boxes typically consist of a metal or glass box and a side door. The side door is sealed with a latch, hinge, or glass panel. In the event of a fire, on-site personnel manually open the box and retrieve the fire extinguisher to put it out.

[0004] However, traditional fire extinguisher boxes have several shortcomings in actual fire scenarios, as shown below:

[0005] Traditional fire boxes lack fire detection capabilities and cannot actively identify abnormal temperatures, smoke, or flames in the surrounding environment. They can only passively wait for personnel to discover the fire and then manually operate, missing the golden time for early warning and rapid response.

[0006] When a fire breaks out, the scene is often accompanied by thick smoke, high temperature and a sharp drop in visibility. In a state of panic, it is difficult for people to quickly find the specific location of the fire extinguisher box. Even if they find it, the glass cover may need to be broken or the metal door may need to be unlocked, which may delay the time to retrieve the extinguisher and seriously affect the efficiency of the initial fire fighting.

[0007] In addition, the existing fire extinguisher boxes lack the ability to link with the fire monitoring system, and cannot send alarm information to the fire control room or remote monitoring platform at the first moment of a fire. This makes it impossible for managers to know the location of the fire and the situation on the ground in a timely manner, which is not conducive to organizing evacuation and dispatching rescue.

[0008] In addition, the opening of traditional fire extinguisher boxes relies entirely on manual operation. If the side door is not closed in time after the fire is extinguished, the fire extinguisher will be exposed to moisture, dust, or human damage for a long time, affecting its reliability for the next use. Summary of the Invention

[0009] The technical problem to be solved by the present invention is to overcome the above-mentioned technical defects and provide a fire extinguisher box with automatic opening and closing and fire early warning functions that shortens the time for retrieving the extinguisher in the early stage of a fire, improves the efficiency of fire extinguishing response, and realizes fire monitoring linkage.

[0010] To solve the above-mentioned technical problems, the technical solution provided by the present invention is: a fire extinguisher box with automatic opening and closing and fire early warning functions, including a box body, a side door on one side of the box body, a storage space that can accommodate fire extinguishers formed inside the box body, and a control module integrated inside the box body;

[0011] It also includes a fire sensing module located on the outside or around the box, which collects environmental fire parameters in real time and transmits them to the control module;

[0012] The box is also equipped with an automatic opening and closing module for controlling the opening and closing of the side door and an early warning output module for outputting fire early warning information.

[0013] The control module is communicatively connected to the fire sensing module, the automatic opening and closing module, and the early warning output module, and is used to generate side door opening and closing commands and fire early warning information based on fire parameters.

[0014] Preferably, the fire sensing module includes at least one of a temperature sensor, a smoke sensor, an infrared flame sensor, and an image acquisition unit, with each sensor distributed on the outer wall of the enclosure or in the monitoring area around the enclosure.

[0015] Preferably, the automatic opening and closing module includes an electric drive unit and a door status detection unit;

[0016] The electric drive unit responds to the side door opening and closing command to perform unlocking and opening actions;

[0017] The door status detection unit feeds back the current open / closed position information of the side door to the control module.

[0018] Preferably, the electric drive unit is any one of an electromagnetic lock, an electric push rod, or a servo motor.

[0019] Preferably, the early warning output module includes an audible and visual alarm unit and a wireless communication unit;

[0020] The audible and visual alarm unit includes a buzzer and an LED warning light, and outputs local audible and visual warning signals;

[0021] The wireless communication unit remotely transmits fire early warning information to the fire monitoring platform.

[0022] Preferably, it also includes a positioning module, which is disposed inside the housing and connected to the control module;

[0023] The positioning module includes an electronic tag storing the box's location code information. The wireless communication unit acquires the box's location code information and remotely transmits the box's location information to the fire monitoring platform.

[0024] Preferably, the control module further includes a delay locking unit, which controls the automatic opening and closing module to keep the side door open for a preset time after the fire parameters return to normal, and generates a side door closing command after the preset time expires.

[0025] Preferably, the fire sensing module further includes a composite discrimination unit, which integrates multi-sensor fusion discrimination rules to fuse and discriminate the detection values ​​of multiple sensors and transmit the discrimination results to the control module;

[0026] The control module executes a tiered response based on the discrimination result:

[0027] A primary warning is triggered when the value detected by a single sensor reaches a preset alarm threshold.

[0028] When the detection values ​​of two or more sensors simultaneously reach their respective preset alarm thresholds, an advanced warning is triggered, and the automatic opening and closing module is controlled to perform the side door opening action.

[0029] The advantages of this invention compared with the prior art are as follows: This invention actively monitors the environmental fire situation through a fire perception module, changing the passive waiting mode of the traditional fire extinguisher box, and achieves graded response through multi-sensor fusion and discrimination, effectively avoiding false alarms;

[0030] This invention automatically opens the side door after confirming the fire, eliminating the time delay of manual searching and opening at the fire scene. The audible and visual alarms facilitate rapid location in low-visibility environments, and the wireless communication linkage with the fire monitoring platform reports the fire and location information in real time.

[0031] The delayed locking unit keeps the side door open for a preset time after the fire has subsided, taking into account both the response to reignition and the protection of equipment, preventing the fire extinguisher from being exposed to moisture, dust, or human damage for a long time, and comprehensively improving the efficiency and reliability of the initial fire response.

[0032] Figure 1 This is a structural diagram of a fire extinguisher box with automatic opening and closing and fire early warning functions.

[0033] Figure 2 This is a schematic diagram of the control logic for a fire extinguisher box with automatic opening and closing and fire early warning functions. Detailed Implementation

[0034] The present invention will now be described in further detail with reference to the accompanying drawings.

[0035] Combined with appendix Figure 1-2 As shown, a fire extinguisher box with automatic opening and closing and fire early warning functions includes a box body, a side door on one side of the box body, and a storage space inside the box body that can accommodate fire extinguishers.

[0036] The box also integrates a control module, which can be an embedded microcontroller or a single-chip microcomputer system. It integrates a signal acquisition interface, a control output interface, a communication interface, a main control unit, and a power management unit, serving as the intelligent control core of the entire fire extinguisher box.

[0037] During use, a fire detection module is installed on the outside or surrounding area of ​​the enclosure. The fire detection module collects environmental fire parameters in real time and transmits them to the control module. An automatic opening and closing module and an early warning output module are also installed inside the enclosure. The automatic opening and closing module is used to control the opening and closing of the side door, and the early warning output module is used to output fire warning information.

[0038] The control module is communicatively connected to the fire sensing module, the automatic opening and closing module, and the early warning output module. The control module receives environmental parameters uploaded by the fire sensing module, and after internal logic judgment, generates a side door opening and closing command and sends it to the automatic opening and closing module. At the same time, it generates fire early warning information and sends it to the early warning output module.

[0039] In one embodiment:

[0040] The fire detection module includes at least one of a temperature sensor, a smoke sensor, an infrared flame sensor, and an image acquisition unit;

[0041] Temperature sensors, such as thermistors or thermocouples, are attached to the outer wall of the enclosure to detect whether the ambient temperature rises abnormally.

[0042] The smoke sensor can be a photoelectric smoke detector, installed on the top outer wall of the enclosure or the surrounding ceiling area, to detect the smoke concentration in the environment;

[0043] An infrared flame sensor is installed on the outer wall of the front of the enclosure to detect infrared radiation from flames at a specific wavelength.

[0044] The image acquisition unit can use a wide-angle camera, which is set on the top of the cabinet to collect real-time video images of the area around the cabinet, so that the background can perform image recognition to assist in judgment.

[0045] When in use, the sensors are distributed on the outer wall of the enclosure or in the monitoring area around the enclosure, forming a three-dimensional fire monitoring network for the surrounding environment of the enclosure.

[0046] The automatic opening and closing module includes an electric drive unit and a door status detection unit. The electric drive unit is installed at the connection or locking part between the cabinet and the side door. In response to the side door opening and closing command issued by the control module, it performs actions such as electromagnetic unlocking, electric push rod pushing out or servo motor rotation, thereby driving the side door to open automatically.

[0047] The door status detection unit uses Hall sensors or microswitches, which are installed on the side door frame or the cabinet door frame to detect in real time whether the side door is fully closed, fully open, or half-open and half-closed, and feeds this position information back to the control module so that the control module can accurately grasp the current status of the side door and avoid repeated driving or misjudgment of status.

[0048] In one embodiment:

[0049] The electric drive unit can be flexibly selected from electromagnetic locks, electric push rods or servo motors, depending on the cabinet structure and side door type.

[0050] When the side door adopts a latch locking structure, the electric drive unit can be an electromagnetic lock. After the control module outputs an unlocking signal, the electromagnetic lock is de-energized and released, and the side door automatically opens under the action of the spring hinge.

[0051] When the side door adopts a sliding structure, the electric drive unit can be an electric push rod, which extends and directly pushes the side door to make it slide outward and open.

[0052] When the side door adopts a revolving door structure, the electric drive unit can be a servo motor, which drives the side door to rotate around the pivot and open through a reduction mechanism.

[0053] The above-mentioned driving method enables the side door to open automatically and quickly, ensuring that personnel can retrieve the device directly without manual operation in an emergency.

[0054] In one embodiment:

[0055] The early warning output module includes an audible and visual alarm unit and a wireless communication unit. The audible and visual alarm unit includes a buzzer and an LED warning light. The buzzer is installed on the top or inner wall of the enclosure and can output a high-decibel intermittent buzzing or continuous alarm sound. The LED warning light is installed on the outer wall of the front of the enclosure and can output a high-frequency flashing red or orange light to form a clear visual guide in a dense smoke environment.

[0056] The wireless communication unit can use a WiFi module, a 4G / 5G communication module, or a LoRa IoT module, installed inside the enclosure, to remotely transmit fire early warning information to the fire monitoring platform or the building fire control center, enabling remote real-time reporting of fire situations.

[0057] In one embodiment:

[0058] The fire extinguisher box is also equipped with a positioning module, which is connected to the control module. The positioning module includes an electronic tag that stores the box's location code information. The electronic tag can be an RFID tag or a storage chip with a pre-set unique identification code. This location code information is written during installation and corresponds to the specific floor, area, and coordinates of the fire extinguisher box within the building.

[0059] When the wireless communication unit sends a fire warning to the fire monitoring platform, it simultaneously obtains the cabinet location code information stored in the electronic tag and transmits the cabinet location information remotely along with the fire data, so that the fire monitoring platform can accurately know the location of the fire extinguisher cabinet where the fire occurred, which facilitates the rapid dispatch of rescue forces.

[0060] For ease of use, the control module also includes a delay lock unit, which is implemented through a software timer or a hardware timing circuit.

[0061] When the fire detection module detects that the fire parameters have returned to normal, that is, the ambient temperature, smoke concentration and other parameters have fallen back to below the normal threshold, the delay locking unit does not immediately control the automatic opening and closing module to close the side door, but keeps the side door open for a preset time, which can be set to ten minutes to thirty minutes.

[0062] If the fire reignites within the preset time, personnel can still retrieve the extinguisher directly without waiting for the side door to reopen. After the preset time expires, the delay locking unit generates a side door closing command, and the control module drives the automatic opening and closing module to perform the closing action, so that the side door returns to its normally closed state and protects the internal fire extinguisher from the influence of the external environment.

[0063] In one embodiment:

[0064] The fire perception module also includes a composite discrimination unit, which integrates multi-sensor fusion discrimination rules. The composite discrimination unit receives multiple detection signals from the temperature sensor, smoke sensor, infrared flame sensor and image acquisition unit, and makes a comprehensive judgment according to the preset fusion discrimination rules.

[0065] If the detection value of a single sensor reaches the preset alarm threshold, it is judged as a suspected fire. The composite discrimination unit outputs the primary discrimination result to the control module. The control module triggers the primary warning, which only drives the audible and visual alarm unit in the warning output module to emit low-frequency flashing and intermittent buzzing to remind on-site personnel to pay attention to the investigation, but does not open the side door to avoid false alarms that may expose the fire extinguisher.

[0066] When the detection values ​​of two or more sensors simultaneously reach their respective preset alarm thresholds, such as when the temperature sensor detects a temperature exceeding the set temperature (e.g., 60°C) and the smoke sensor detects a smoke concentration exceeding the set value, the composite discrimination unit determines that a fire has been confirmed and outputs an advanced discrimination result to the control module. The control module triggers an advanced early warning and simultaneously drives the early warning output module to emit high-frequency flashing and continuous alarms. It also controls the automatic opening and closing module to immediately execute the side door opening action and sends fire alarm information containing location codes to the fire monitoring platform through the wireless communication unit.

[0067] In this invention, a graded response mechanism effectively balances the timeliness of fire response with the reliability of alarm judgment, avoiding false alarms caused by environmental interference from a single sensor.

[0068] In a specific implementation of this invention, the fire extinguisher box is installed in a key fire protection area within the building. The fire sensing module continuously monitors the surrounding environmental parameters. When a fire occurs in the surrounding area, the composite discrimination unit fuses and discriminates data from multiple sensors. If a single sensor reaches a threshold, a primary warning is triggered.

[0069] If multiple sensors confirm the fire, an advanced warning will be triggered, the side door will open automatically, the audible and visual alarms will be activated, and the fire situation and location information will be remotely pushed to the fire monitoring platform.

[0070] On-site personnel can quickly locate the enclosure by following the sound and light guidance, and directly take out the fire extinguisher from the opened side door for initial firefighting. After the fire is extinguished, the delay locking unit keeps the side door open for a preset time, and then automatically closes the side door and resumes normal monitoring.
