Description

Technical Field

[0001] This utility model relates to the field of fire alarm linkage device technology, and in particular to a fire alarm linkage device for use in industrial and commercial energy storage cabinets. Background Technology

[0002] With the rapid development of industry and commerce, energy storage cabinets are being used more and more widely in various places. However, the fire safety issues of energy storage cabinets have also become prominent. Once a fire occurs, if it cannot be extinguished in a timely and effective manner, it will cause huge property losses and even endanger people's lives.

[0003] Traditional fire-fighting measures have several shortcomings when dealing with energy storage cabinet fires. Firstly, some early fire detection devices have low sensitivity and slow response times, failing to accurately detect changes in smoke and temperature in the early stages of a fire, leading to delayed alarms and missed opportunities for optimal fire suppression. For example, some conventional temperature and smoke sensors may be technically limited and unable to quickly detect fire signals in the complex environment of an energy storage cabinet, allowing the fire to spread undetected. Secondly, fire extinguishing devices are often not activated quickly or intelligently. Many traditional fire extinguishing devices lack efficient linkage mechanisms with front-end detection equipment, failing to react immediately upon receiving a fire signal. Instead, they require manual intervention or cumbersome procedures to activate, significantly reducing the timeliness of fire suppression and hindering timely and effective early fire control, making it easy for the fire to spread uncontrollably and cause more serious consequences.

[0038] It includes an audible and visual alarm module, which is connected to the control module.

[0039] It is understandable that when the control module receives temperature and smoke signals, if the comparison result is abnormal, it will immediately activate the audible and visual alarm module.

[0040] The fire alarm linkage device includes an overcurrent protection module, which is installed between the power supply and the switching power supply.

[0041] The overcurrent protection module is a miniature circuit breaker.

[0042] It is understood that when the control module receives temperature and smoke signals, if the comparison result is abnormal, it will immediately trigger a miniature circuit breaker to cut off the non-fire-fighting power supply to ensure the safety of the fire scene. The control module includes a time delay module, which is connected to the control module and is used to control the time from the stop to the start of the fire extinguishing device.

[0043] The energy storage cabinet is equipped with an actuator, which is connected to the control module. The actuator is used to control the opening and closing status of all openings inside the energy storage cabinet according to the closing command output by the control module.

[0044] All openings inside the energy storage cabinet include fire doors, ventilation holes, and fan vents.

[0045] Understandably, when the fire extinguishing device is activated, all openings inside the energy storage cabinet are closed by the control module through the actuator, effectively preventing the fire from spreading.

[0046] It includes an explosion-proof machine, which is connected to a control module and is used to discharge combustible gases from the energy storage cabinet.

[0048] The miniature circuit breaker's input terminal is connected to 220V AC power, and its output terminal is connected to the L and N terminals of the switching power supply.

[0049] The 1+ terminal of the switching power supply is connected to the L1IN terminal of the smoke sensor, and the 1- terminal of the switching power supply is connected to the L2 terminal of the temperature sensor.

[0050] The temperature sensor's L2 terminal is also connected to the smoke sensor's L2 terminal, the temperature sensor's C terminal is connected to the smoke sensor's NO terminal, and the temperature sensor's NO and L2 terminals are respectively connected to the + and - input terminals of the fire extinguishing aerosol device; and respectively connected to the display and control system's DI1H and VDD terminals.

[0051] The NO and L2 terminals of the smoke sensor are connected to the + and - input terminals of the audible and visual alarm, respectively.

[0052] The DI+ and DI- terminals of the fire extinguishing aerosol device are connected to the DI1H and VDD terminals of the display and control system, respectively.

[0053] The specific workflow of this embodiment is as follows:

[0054] The display and control system below is a system with the above-mentioned control module as the control center;

[0055] When the display and control system receives abnormal fire signals (smoke and temperature signals) detected by the smoke and temperature sensors inside the energy storage cabinet, it will issue a fire extinguishing command and activate the thermal aerosol fire extinguishing device. The display and control system will then perform the following operations:

[0056] S1. First, the sound and light alarm in the cabinet will be triggered, flashing and sounding an alarm.

[0057] S2. The display and control system counts down the release of the thermal aerosol fire extinguishing device according to the delay time set by the delay module (the delay time can be adjusted according to the actual application scenario and location).

[0058] S3. During the delay period, the display and control system will drive the actuator to automatically close all openings, fire doors, heat dissipation and ventilation holes and fan vents inside the energy storage cabinet.

[0059] S4. The display and control system will monitor whether all modules are operating normally.

[0060] S5. After the delay phase ends, immediately issue a start-up command to the thermal aerosol fire extinguishing device;

[0061] S6. After the thermal aerosol fire extinguishing device is activated, it generates a large amount of extinguishing medium, which is then sprayed into the fire area to extinguish the fire.

[0062] S7. At the same time, a feedback signal is output after the thermal aerosol generator reacts, and the signal is transmitted to the display and control system.

[0063] S8. Five to ten seconds after the spray signal is triggered, the explosion-proof fan receives the alarm signal from the display and control system, and the explosion-proof fan starts to work and discharges the combustible gas generated in the cabinet during the fire extinguishing process.

[0064] Note that personnel should not enter the energy storage cabinet working area while the display and control system is in operation. Ventilation should only be carried out after the fire inside the energy storage cabinet has been extinguished, and the area where the fire occurred should be cleaned up at the same time.

[0065] In terms of response speed, smoke and temperature sensors, as the system's front-end detection devices, can quickly sense changes in smoke and temperature in the early stages of a fire. These sensors possess high sensitivity and rapid response characteristics; once an anomaly is detected, they immediately transmit the signal to the display and control system, significantly shortening the fire alarm time. Simultaneously, upon receiving the alarm signal, the display and control system immediately activates the audible and visual alarms and triggers a miniature circuit breaker to cut off non-fire-fighting power, ensuring safety at the fire scene. Furthermore, integrated aerosol devices and other fire extinguishing equipment will also be quickly activated to provide initial fire control and effectively prevent the fire from spreading.

[0066] In terms of environmental adaptability, electrical components such as miniature circuit breakers and switching power supplies exhibit excellent environmental adaptability and can operate stably in various harsh electrical environments. Meanwhile, smoke and temperature sensors are specially designed to withstand complex environments such as high temperature, high humidity, and dust, ensuring the accuracy and reliability of detection. Furthermore, the display and control system possesses intelligent adjustment capabilities, automatically adjusting alarm thresholds and linkage strategies according to different fire conditions and environmental circumstances, thereby improving the overall adaptability and stability of the system.

[0067] Regarding the linkage mechanism between the fire protection system and the energy storage system, the fire protection linkage system adopts a highly integrated control method, tightly connecting all components to form a unified whole. In the event of a fire, the system can automatically execute preset linkage procedures, achieving rapid and accurate fire alarm and fire extinguishing control. The various components share information and work collaboratively through communication protocols. The display and control system can receive data from various sensors in real time and perform comprehensive analysis and processing. Simultaneously, the system also has remote monitoring and diagnostic functions, facilitating remote management and maintenance by administrators.

[0068] Therefore, the fire alarm linkage system for industrial and commercial energy storage cabinets exhibits significant advantages in response speed, environmental adaptability, and linkage mechanism. These advantages make the system of significant value in fire prevention and control.
