Technical Field

[0001] The utility model belongs to the technical field of energy storage equipment, and in particular relates to an industrial and commercial energy storage cabinet fire protection system. Background Art

[0002] With the rapid development of energy storage technology, industrial and commercial energy storage applications are becoming increasingly widespread. Today's industrial and commercial energy storage equipment is usually an energy storage cabinet composed of multiple battery packs. These battery packs will emit a lot of heat during the charge and discharge cycle, and there is a potential risk of thermal runaway. Especially under abnormal conditions such as overcharging and overload operation, the chemical reaction inside the battery intensifies and the heat generation increases significantly. Once the heat accumulation leads to thermal runaway, it may cause a fire or even an explosion, posing a major safety threat to the energy storage system.

[0003] Given the huge amount of energy stored in industrial and commercial energy storage cabinets, when many battery packs are densely arranged, it is difficult for traditional fire protection systems to conduct detailed status monitoring and directional fire extinguishing of individual battery packs. In addition, the traditional fire protection system has a complex structure, which is not only difficult to install and maintain, but also generally relies on smoke detectors, and the layout of the smoke detectors is often not scientific enough, resulting in low monitoring accuracy and easy to generate false alarms, which in turn leads to ineffective use of fire extinguishing media.

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0023] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0024] like Figure 1 , Figure 2 As shown, an industrial and commercial energy storage cabinet fire protection system includes an energy storage component 1, a sensor 2, a puncture valve 3, a nozzle 4 and a fire-fighting gas cylinder 5.

[0025] like Figure 1 , Figure 2 As shown, an industrial and commercial energy storage cabinet fire protection system includes:

[0026] An energy storage component 1, wherein a plurality of energy storage components 1 are provided, and each energy storage component 1 is provided with a sensor 2 for monitoring the state of the energy storage component 1;

[0027] A fire-fighting component, which includes a puncture valve 3, a nozzle 4 and a fire-fighting gas cylinder 5 that are interconnected. The puncture valve 3 is provided in plurality and corresponds one-to-one with a plurality of energy storage components 1. The nozzle 4 is provided in plurality, one end of each nozzle 4 is connected to the energy storage component 1, and the other end is connected to the puncture valve 3. One end of each puncture valve 3 is connected to the fire-fighting gas cylinder 5, and the other end is connected to the nozzle 4. The puncture valve 3 and the fire-fighting gas cylinder 5 are respectively connected to the sensor 2 in communication. Through the setting of the sensor 2, the state of each energy storage component 1 can be finely monitored, ensuring accurate perception and rapid response to the fire conditions of each energy storage component 1 in the energy storage cabinet. When the state of a certain energy storage component 1 is detected to be abnormal (there is a fire hazard), the puncture valve 3 and the fire cylinder 5 are controlled to open, so that the fire-fighting medium can sequentially pass through the puncture valve 3 and the nozzle 4 to extinguish the fire inside the corresponding energy storage component 1, realizing independent and accurate fixed-point fire extinguishing for a single energy storage component 1, avoiding the spread of the fire source, and improving the overall fire-fighting efficiency; and the communication connection between the sensor 2 and the puncture valve 3 and the fire cylinder 5 enables the fire-fighting system to automatically trigger the fire-fighting operation, realizing intelligent fire prevention and control, and enhancing the active protection performance of the system. In addition, since each energy storage component 1 corresponds to a puncture valve 3 separately, the fire-fighting medium is avoided from being diverted when entering a single energy storage component 1 through the puncture valve 3 and the nozzle 4, so that the puncture valve 3 can provide stable pressure supply when transmitting the fire-fighting medium, thereby ensuring the stability of the fire-fighting medium transmission and the nozzle 4 fire extinguishing.

[0028] like Figure 1 , Figure 2 As shown, in this embodiment, the energy storage component 1 is a battery pack, and a plurality of energy storage components 1 are provided, and the plurality of energy storage components 1 are stacked in sequence longitudinally to form an energy storage cabinet with huge energy storage capacity to meet the energy storage needs of users.

[0029] In order to realize real-time monitoring of the status of each energy storage component 1, in the present embodiment, each energy storage component 1 is provided with a sensor 2 for monitoring the status of the energy storage component 1, and the sensor 2 is respectively connected to the puncture valve 3 and the fire cylinder 5 through the control system; on the one hand, the status of the energy storage component 1 can be monitored in real time to realize fire prevention of the energy storage component 1, and on the other hand, the puncture valve 3 and the fire cylinder 5 can be automatically triggered, thereby realizing automatic triggering of the fire extinguishing operation and realizing intelligent fire prevention and control.

[0030] In this embodiment, the sensor 2 is a composite sensor 2, which includes a gas sensing module for simultaneously monitoring multiple gas values ​​and a temperature sensing module for monitoring temperature values. The gas sensing module and the temperature sensing module feed back the monitored gas values ​​and temperature values ​​into electrical signals to the control system to monitor the state of the energy storage component 1. Through the integration of the gas sensing module and the temperature sensing module, the concentrations of multiple gases and temperature changes inside the energy storage component 1 can be fully monitored, effectively improving the accuracy of fire monitoring and early warning capabilities.

[0031] Preferably, in this embodiment, the detection gas includes but is not limited to carbon monoxide, hydrogen or volatile organic compounds.

[0032] In this embodiment, the control system is used to receive the electrical signal of the sensor 2 for data analysis, and send an electrical signal to the puncture valve 3 or the fire cylinder 5 according to the analysis structure to activate the puncture valve 3 and / or the fire cylinder 5, so that the fire protection system can operate automatically and accurately extinguish fires.

[0033] In this embodiment, the control system also includes an alarm module, which generates an alarm signal based on the analysis data of the control system and sends the alarm signal to the control console, so that the user can promptly notify relevant personnel for emergency processing or evacuation according to the alarm signal, effectively improving the timeliness of fire response, helping to reduce fire losses and ensure personnel safety.

[0034] It is worth noting that, in the present embodiment, the alarm signal is divided into different levels of alarm signals (such as a first-level alarm signal, a second-level alarm signal and a third-level alarm signal) according to the size of the gas concentration and the temperature value, and different levels of alarm signals activate the corresponding puncture valve 3 or fire cylinder 5. For example, when the gas concentration and the temperature value are between the first preset value and the second preset value, the first-level or second-level alarm signal is activated, and only the puncture valve 3 is triggered to start; when the gas concentration and the temperature value exceed the second preset value, the third-level alarm signal is activated, and the fire cylinder 5 is triggered to start, so as to avoid false alarms and ineffective use of fire-fighting media.

[0035] In order to improve the safety of the energy storage cabinet, in this embodiment, the energy storage cabinet is equipped with a firefighting assembly, which includes a puncture valve 3, a nozzle 4 and a fire cylinder 5 connected to each other. Among them, there are a plurality of puncture valves 3, which correspond to a plurality of energy storage components 1 one by one, so as to achieve targeted fire extinguishing control of each energy storage component 1, and at the same time ensure the stability of each energy storage component 1 when extinguishing a fire.

[0036] In this embodiment, a plurality of puncture valves 3 are arranged longitudinally in sequence, and the arrangement direction is consistent with the stacking direction of the energy storage components 1, so as to ensure the compactness of the overall structure of the energy storage cabinet fire protection system, thereby improving the space utilization of the energy storage cabinet.

[0037] In this embodiment, one end of a plurality of puncture valves 3 is connected in series to a fire-fighting gas cylinder 5, and the other end is connected to a corresponding nozzle 4. When a fire occurs in any energy storage component 1, the fire-fighting gas cylinder 5 can supply the fire-fighting medium, ensuring that any energy storage component 1 can be effectively extinguished. In addition, the series arrangement of a plurality of puncture valves 3 cleverly utilizes the characteristics of the puncture valve 3 with a three-way structure, realizes full utilization of the puncture valve 3, thereby effectively saving the connecting pipe, reducing the manufacturing cost of the fire-fighting system, and ensuring the compactness of the fire-fighting system layout.

[0038] It should be noted that, in the present embodiment, when the puncture valve 3 is not opened, the interior of the energy storage cabinet remains sealed, and when the puncture valve 3 is opened and the fire-fighting gas cylinder 5 is opened synchronously, the fire-fighting medium of the fire-fighting gas cylinder 5 can enter the nozzle 4 through the puncture valve 3, and the nozzle 4 performs a fire-fighting operation on the battery pack at a fixed point.

[0039] Preferably, in this embodiment, each puncture valve 3 includes an input end 31, an output end 32 and a connection end 33 that are interconnected, wherein the input end 31 is connected to the fire cylinder 5 through a first pipe 6, and the output end 32 is connected to the nozzle 4 through a third pipe 8 to realize the transmission of the fire-fighting medium, and the connection end 33 is used to realize the series connection between two adjacent puncture valves 3, so that the fire-fighting gas cylinder 5 can supply the fire-fighting medium to multiple nozzles 4.

[0040] It is worth noting that the output end 32 is only turned on after the puncture valve 3 is opened, while the input end 31 and the connection end 33 are always in a conducting state to ensure that when any puncture valve 3 and the fire-fighting gas cylinder 5 are opened synchronously, the fire-fighting medium can extinguish the corresponding energy storage component 1.

[0041] In this embodiment, a plurality of nozzles 4 are provided, which are respectively provided on each energy storage component 1, and one end of each nozzle 4 is connected to the energy storage component 1, and the other end is connected to the puncture valve 3, serving as an output point for fixed-point fire extinguishing.

[0042] In this embodiment, each energy storage component 1 corresponds to a nozzle 4 and a puncture valve 3, respectively, which effectively ensures the efficient allocation and targeted use of fire extinguishing resources.

[0043] In this embodiment, the plurality of puncture valves 3, the plurality of nozzles 4 and the fire-fighting gas cylinder 5 are all detachably connected via a connecting pipe, which can facilitate the installation, maintenance and replacement of the system and enhance the flexibility and maintainability of the system.

[0044] In this embodiment, the connecting pipe includes a first pipe 6 arranged between the fire cylinder 5 and the puncture valve 3, a plurality of second pipes 7 arranged between two adjacent puncture valves 3, and a plurality of third pipes 8 arranged between the puncture valve 3 and the nozzle 4. Through the separate design of the first pipe 6, the second pipe 7 and the third pipe 8, the need to replace the connecting pipe as a whole when part of the connecting pipe is damaged can be avoided, thereby improving the utilization rate of the connecting pipe.

[0045] Further, in this embodiment, the two ends of the first pipe 6 are detachably connected and communicated with the fire cylinder 5 and the puncture valve 3, respectively, the two ends of the second pipe 7 are detachably connected and communicated with two adjacent puncture valves 3, respectively, and the two ends of the third pipe 8 are detachably connected and communicated with the puncture valve 3 and the nozzle 4, respectively. When the puncture valve 3 and the fire cylinder 5 are opened, the firefighting medium in the fire cylinder 5 enters the energy storage component 1 through the puncture valve 3 and the nozzle 4 in sequence, and extinguishes the fire of the energy storage component 1. When the puncture valve 3 and the fire cylinder 5 are opened, the firefighting medium can quickly enter the energy storage component 1 according to the preset path, and directly and efficiently extinguish the fire source, thereby ensuring the fire extinguishing performance of the firefighting system.

[0046] Preferably, in this embodiment, the first pipeline 6 includes a plurality of interconnected and detachably connected transverse pipes and vertical pipes, so that the first pipeline 6 can flexibly adjust the pipeline direction according to the actual layout of the energy storage cabinet to adapt to the installation requirements in different scenarios, thereby improving the adaptability and installation convenience of the system.

[0047] In this embodiment, at least one horizontal pipe and a vertical pipe of the first pipeline 6 are connected via a three-way valve 61 to reserve a connection interface for the subsequent addition of energy storage cabinets.

[0048] Preferably, in this embodiment, the second pipes 7 are arranged vertically, and the third pipes 8 are arranged horizontally.

[0049] In this embodiment, the fire-fighting gas cylinder 5 is horizontally arranged on one side of the energy storage component 1, which effectively avoids occupying the longitudinal space around the energy storage cabinet. In addition, combined with the unique structure of the horizontally placed fire-fighting gas cylinder 5, a stable supply of fire-fighting medium can also be achieved.

[0050] Preferably, in this embodiment, the firefighting medium in the firefighting gas cylinder 5 is perfluoroacetone.
