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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, this utility model provides an energy storage fire-fighting device, including a cabinet 1. The cabinet 1 contains an electrical compartment 3 and a battery compartment 4. Several battery packs 5 are fixedly connected inside the battery compartment 4. A composite detector 15 and a solenoid valve nozzle 7 are pre-installed in the battery pack 5's structural design and installed during battery pack 5 assembly. Cable laying and connection cables should be laid along the top, sides, or cable trays of the cabinet, requiring aesthetically pleasing workmanship and reliable connections. A mounting plate 6 is fixedly connected to the upper surface of the battery pack 5, and a solenoid valve nozzle 7 is mounted on the mounting plate 6. A mounting base 8 is fixedly connected to the inner bottom surface of the electrical compartment 3, and a groove 10 is provided inside the mounting base 8. A bottom plate is fixedly connected to the inner surface of the groove 10. A spring 12 is fixedly connected to the outer surface of the base plate 11. A fixing plate 13 is fixedly connected to the end of the spring 12 away from the base plate 11. A clamping plate 14 is fixedly connected to the outer surface of the fixing plate 13. A perfluorohexanone fire extinguisher 9 is placed in the mounting base 8. Specifically, the perfluorohexanone fire extinguishing device is an independent set of fire extinguishing equipment that is pre-assembled according to certain application conditions, including a fire extinguishing agent storage device and an electromagnetic drive device. It is suitable for extinguishing fires in small enclosed protected areas by total flooding. It can be connected to the fire control center and automatically extinguished by linkage with the fire alarm controller 17. The clamping plate 14 can lock the perfluorohexanone fire extinguisher 9.

[0024] Specifically, a partition 2 is fixedly connected inside the cabinet 1, which divides the cabinet 1 into an electrical compartment 3 and a battery compartment 4.

[0025] Furthermore, the upper side of the card plate 14 is sloping and rounded, and a rubber plate is fixedly connected to the outer surface of the card plate 14.

[0026] Furthermore, the size of the card plate 14 is smaller than that of the groove 10, and the card plate 14 abuts against the outer wall of the perfluorohexanone fire extinguisher 9.

[0027] It is worth noting that the output end of the perfluorohexanone fire extinguisher 9 is fixedly connected to a pipe 16, and the other end of the pipe 16 passes through the mounting plate 6 and is fixedly connected to the solenoid valve nozzle 7.

[0028] It is worth noting that the inner surface of the electrical compartment 3 is fixedly connected to the first base, and the outer surface of the first base is fixedly connected to the controller 17.

[0029] It is worth mentioning that a second base is fixedly connected to the upper surface of the electrical compartment 3, and an audible and visual alarm 18 is fixedly connected to the upper surface of the second base.

[0030] It is worth emphasizing that a composite detector 15 is fixedly connected to the upper surface of each battery pack 5, integrating heat, smoke, CO, and VOC gas detection elements. Specifically, it is a composite fire detection device for energy storage, detecting carbon monoxide, VOC, smoke, and heat (hereinafter referred to as the detector), which detects early fire hazards and fires inside the energy storage lithium battery box. The detector can independently perform graded alarms and independently and automatically activate the suppression device. It can also be connected to the controller 17 to trigger the fire suppression device automatically / manually to suppress the fire. It integrates hazard reporting, fire identification, and emergency fire extinguishing. The detector adopts a split installation. The monitoring part is inside the battery pack 5, and the circuit control part is outside. It monitors the changes of parameters such as electrolyte gas (volatile organic compounds), combustion characteristic gas (carbon monoxide), smoke, and temperature in the area in real time. Through multi-sensor data fusion algorithms, it determines whether there is a fire hazard or a fire has occurred, and issues graded alarm information.

[0031] The audible and visual alarm 18, the solenoid valve nozzle 7, and the composite detector 15 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, a controller 17, and switches, which are not the main technical points of this patent and will not be described in detail. The "front, back, left, and right" viewing angles of this device are... Figure 1 The direction shown in the diagram is the reference.

[0032] Working principle: During installation, the perfluorohexanone fire extinguisher 9 is inserted into the mounting base 8 by pressing the two clamping plates 14 until it reaches the bottom of the mounting base 8. After installation, the spring 12 on the base plate 11 applies elastic force to the clamping plates 14, and the perfluorohexanone fire extinguisher 9 is clamped and fixed by the clamping force of the two clamping plates 14. During use, when the composite detector 15 outputs a first-level alarm signal, the controller 17 sends the detected warning information to the management system. Abnormal situations can be confirmed by manually checking the site and appropriate actions can be taken according to the actual situation. When the composite detector 15 outputs a second-level alarm signal, the controller... 17 sends the detected early warning information to the management system. Abnormal situations can be confirmed by manual inspection of the site and appropriate measures can be taken according to the actual situation. If it is necessary to link other equipment, it can be set according to actual needs, such as activating the audible and visual alarm 18. When the composite detector 15 outputs a level 3 alarm signal, the controller 17 sends the detected early warning information to the management system, and at the same time opens the solenoid valve nozzle 7 of the corresponding protected area and activates the perfluorohexanone fire extinguisher 9. The perfluorohexanone fire extinguisher 9 is delivered to the solenoid valve nozzle 7 through the pipeline 16. The extinguishing agent is sprayed into the corresponding protected area through the pipeline and nozzle to implement fire protection.

[0033] The Level 1 warning is triggered when the temperature reaches the primary threshold, the smoke reaches the primary threshold, and the carbon monoxide reaches the intermediate threshold.

[0034] Level 2 Alert: Temperature reaches the intermediate threshold, smoke reaches the intermediate threshold and carbon monoxide reaches the intermediate threshold, volatile organic compounds reach the alarm threshold and smoke reaches the intermediate threshold, temperature changes suddenly and smoke reaches the intermediate threshold, temperature changes suddenly and carbon monoxide reaches the intermediate threshold.

[0035] Level 3 warning: Temperature reaches high threshold, smoke reaches high threshold and carbon monoxide reaches high threshold and temperature changes abruptly, smoke reaches high threshold and carbon monoxide reaches high threshold and temperature reaches medium threshold, smoke reaches high threshold and volatile organic compounds reach threshold and temperature reaches medium threshold, smoke reaches high threshold and volatile organic compounds reach threshold and temperature changes abruptly.

[0036] Primary temperature threshold: 65℃; Intermediate temperature threshold: 75℃; Advanced temperature threshold: 85℃;

[0037] Rapid temperature rise: The temperature rises by more than 15°C cumulatively within any 60 seconds after reaching 30°C;

[0038] Intermediate threshold for carbon monoxide: 410 ppm; High threshold for carbon monoxide: 738 ppm; Alarm threshold for volatile organic compounds: 684 ppm;

[0039] Primary smoke threshold: 400 (approximately 0.6 dB / m); Intermediate smoke threshold: 600 (approximately 0.9 dB / m).

[0040] Advanced smoke threshold: 1000 (approximately 1.5 dB / m).

[0041] When the detector triggers a level 1 or 2 alarm, the fire extinguisher can be activated via message command. When the detector triggers a level 3 alarm, the fire extinguisher will be activated automatically. Note: The alarm logic level threshold can be adjusted as needed.
