Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing device technology, and in particular to a novel intelligent gas fire extinguishing device. Background Technology

[0002] The integrated fire alarm and extinguishing unit is a comprehensive fire protection device that combines fire alarm and fire extinguishing functions. It is widely used in modern buildings, industrial plants, commercial centers and other places.

[0003] In existing technologies, built-in sensors (such as smoke detectors and temperature detectors) can monitor fire signs in the environment in real time, such as smoke concentration and temperature changes. Once an anomaly is detected, the device will immediately issue an audible and visual alarm signal to alert personnel to take action. However, in most current products, the alarm signal of the controller is transmitted to other alarm devices through wiring terminals. The controller itself cannot indicate whether an alarm has occurred, which makes it impossible for on-site personnel to directly determine whether an alarm has occurred from the controller, increasing the risk of misjudgment. Furthermore, once the controller is powered off, all protection functions fail, and only the over-temperature activation fire suppression mode remains. This may result in the fire suppression function not being triggered in time in the early stages of a fire, increasing the fire risk. When the controller is connected to the host, setting the address must be completed through host communication. Some devices cannot be set with addresses and can only be connected one-to-one, which limits the system's scalability and flexibility and increases the complexity of installation and maintenance.

[0004] To address the aforementioned shortcomings, a novel intelligent gas fire extinguishing device is provided. Utility Model Content

[0005] The purpose of this utility model is to propose a novel intelligent gas fire extinguishing device in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a novel intelligent gas fire extinguishing device, comprising a controller body and a fire extinguishing device body. The controller body is equipped with an address DIP switch, wiring terminals, and a communication module. Both the controller body and the fire extinguishing device body are equipped with an alarm triggering mechanism. The controller body contains a control circuit board and a backup power supply. The output terminal of the alarm triggering mechanism is electrically connected to the input terminal of the control circuit board. The output terminal of the control circuit board is electrically connected to the input terminals of the communication module and the fire extinguishing device body.

[0007] Preferably, the communication module is an antenna installed on the controller body.

[0008] Preferably, the communication module is an RS485 communication port installed on the controller body.

[0009] Preferably, the alarm triggering mechanism includes a smoke sensor installed in the controller body, a start button installed on the top of the controller body, and a heat-sensitive wire installed on the top of the fire extinguishing device body.

[0010] Preferably, a slide block is slidably connected to the top of the controller body, a housing is rotatably connected to the outside of the slide block, the controller body is provided with an elastic buckle structure that cooperates with the housing for fixation, a handle is fixedly provided on the side end of the housing, and a torsion spring abuts between the slide block and the housing.

[0011] Preferably, the elastic buckle structure includes two baffles fixed to the top of the controller body, a crossbar that slides through the slide block is fixed between the two baffles, a compression spring that acts on the slide block is sleeved on the outside of the crossbar, an inclined block is formed on the inner wall of the housing, and a buckle that cooperates with the inclined block is fixed to the top of the controller body.

[0012] Preferably, the controller body is also equipped with an indicator light, and the input terminal of the indicator light is electrically connected to the output terminal of the control circuit board.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, the controller itself is equipped with operation, alarm, mute, and communication indicator lights. By observing these indicator lights, users can understand whether the controller is operating normally, communicating, or experiencing any alarm events. It also has a built-in buzzer, which will alert the user audibly when an alarm occurs. This dual visual and auditory alert allows users to respond to alarm events more quickly, ensuring user safety.

[0015] 2. In this application, the controller can continue to operate for at least 20 seconds after a power outage. Connected to the host computer via network, the controller sends a power outage alarm message, and the controller itself also emits corresponding audible and visual signals to alert the user that the equipment has been powered off. During this period, the controller can still trigger fire suppression through various triggering methods, thereby improving the system's reliability and safety.

[0016] 3. In this application, device parameters or addresses are set through address DIP switches. By combining the states of multiple switch positions, various different encodings can be achieved. Addresses can be set without a host computer, facilitating quick device address setup and simplifying the installation and debugging process. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1-3 This utility model provides a technical solution:

[0024] A novel intelligent gas fire extinguishing device includes a controller body 1 and a fire extinguishing device body 18. The controller body 1 is equipped with an address DIP switch 2, a wiring terminal 6, and a communication module. Both the controller body 1 and the fire extinguishing device body 18 are equipped with an alarm triggering mechanism. The controller body 1 contains a control circuit board and a backup power supply. The output of the alarm triggering mechanism is electrically connected to the input of the control circuit board. The output of the control circuit board is electrically connected to the input of the communication module and the fire extinguishing device body 18.

[0025] The address DIP switch 2 is an existing technology that uses binary encoding. By manually toggling the switch, the on / off state of the circuit is changed, thereby setting device parameters or addresses. Each switch position corresponds to a binary bit; "ON" represents "1," and "OFF" represents "0." By combining the states of multiple switch positions, various different encodings can be achieved. Address setting can be done without a host computer, facilitating rapid device address configuration and simplifying installation and debugging.

[0026] The communication module connects to the alarm and fire suppression system host or platform, enabling remote monitoring and centralized management. The backup power supply ensures that the controller can continue operating for at least 20 seconds after a power outage. It can connect to the host or platform via RS485 or 4G antenna 5. When connected, the controller sends a power outage alarm to the host, and the controller itself emits corresponding audible and visual signals to alert the user that the equipment has been powered down. During this period, the controller can still trigger fire suppression through various methods.

[0027] Both the controller body 1 and the fire extinguishing device body 18 are equipped with alarm triggering mechanisms. The redundancy of the system is enhanced by setting multiple triggering methods. Even if one component fails, the other component can still trigger the alarm.

[0028] Specifically, such as Figure 1 As shown, the communication module is the antenna 5 installed on the controller body 1.

[0029] The wireless communication module transmits data through antenna 5, eliminating the need for wiring and making installation and debugging more flexible. It is suitable for use in scenarios where wiring is difficult or where frequent mobile devices are required.

[0030] The communication module is an RS485 communication port installed on the controller body 1. RS485 is a standard serial communication interface that supports long-distance, multi-node communication, has strong anti-interference capabilities, and is suitable for industrial environments.

[0031] The fire extinguishing device body 18 adopts the existing gas hot melt adhesive fire extinguishing device. This fire extinguishing agent is environmentally friendly, non-corrosive, and does not damage the equipment.

[0032] Specifically, such as Figure 1 As shown, the alarm triggering mechanism includes a smoke sensor 3 installed in the controller body 1, a start button 8 installed on the top of the controller body 1, and a heat-sensitive wire 19 installed on the top of the fire extinguishing device body 18.

[0033] The smoke sensor 3 is used to detect smoke particles in the air, and triggers an alarm once the set threshold is exceeded.

[0034] The start button 8 allows manual activation of the alarm or fire suppression system.

[0035] The heat-sensitive wire 19 identifies fires by detecting sudden increases in temperature. When the temperature at any point on the built-in heat-sensitive detection wire exceeds 170 degrees Celsius, it automatically triggers fire suppression.

[0036] Specifically, such as Figure 1As shown, a slide block 9 is slidably connected to the top of the controller body 1, and a housing 10 is rotatably connected to the outside of the slide block 9. The controller body 1 is provided with an elastic buckle structure that cooperates with the housing 10 for fixation. A handle 12 is fixed to the side end of the housing 10, and a torsion spring 17 abuts between the slide block 9 and the housing 10.

[0037] The cover 10 is placed on the outside of the start button 8 to prevent accidental activation. When manual start is required, the user only needs to pull the handle 12 to make the slide 9 slide along the top of the controller body 1. The elastic buckle structure releases the restriction on the cover 10. At this time, the cover 10 will quickly spring up under the action of the torsion spring 17, making it convenient for the user to operate the start button 8.

[0038] The elastic buckle structure includes two baffles 14 fixed to the top of the controller body 1, a crossbar 15 that slides through the slide block 9 fixed between the two baffles 14, a compression spring 16 that acts on the slide block 9 sleeved on the outside of the crossbar 15, an inclined block 11 formed on the inner wall of the cover 10, and a lock 13 that cooperates with the inclined block 11 fixed on the top of the controller body 1.

[0039] Both the latch 13 and the inclined block 11 have slopes and planes. When the cover 10 needs to be closed, the user pulls the cover 10 through the handle 12. When the cover 10 is turned to block the start button 8, the relative slopes of the latch 13 and the inclined block 11 slide together, causing the cover 10 to pull the slide block 9 along the crossbar 15 until the slopes of the latch 13 and the inclined block 11 slide out of alignment. At this time, the handle 12 is released, and the slide block 9 will move the cover 10 under the action of the compression spring 16, so that the inclined block 11 and the latch 13 are engaged. At this time, the planes of the inclined block 11 and the latch 13 are in contact, thereby restricting the cover 10 from rotating and lifting at will.

[0040] Specifically, such as Figure 1 As shown, the controller body 1 is also equipped with indicator lights 7 and buttons 4. There are four indicator lights 7. The input terminals of the indicator lights 7 are electrically connected to the output terminals of the control circuit board, respectively responsible for indicating the operation, alarm, mute, and communication of the controller body 1. By observing the indicator lights 7, users can understand whether the controller is operating normally, communicating, or experiencing any alarm events. It also has a built-in buzzer, which will alert the user audibly when an alarm occurs. There are two buttons 4, providing a mute and a reset button. The mute button allows the user to actively silence the current alarm sound signal, and the reset button allows the user to restart the controller without interrupting power.

[0041] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
