Description

Technical Field

[0001] The present application relates to the field of energy storage technology, and more specifically, to a fire extinguisher cabinet and an energy storage system. Background Art

[0002] With the rapid development of energy storage systems, their safety has also attracted widespread attention. For example, to meet the fire protection design requirements of energy storage systems, energy storage systems must have fire alarm functions. The mainstream fire alarm solution currently used in energy storage systems is to install dry contact smoke and temperature sensors in the energy storage cabinet for detection. With this fire alarm solution, when a fire occurs in the energy storage system, the user receives the fire alarm and needs to conduct further on-site inspection to determine the specific cabinet location where the fire has occurred, and then extinguish the fire at that location. However, the process of inspecting and determining the specific location of the fire can take a considerable amount of time, and during this period, there is a risk that the fire at the fire location will spread, ultimately leading to delayed fire rescue.

[0003] In summary, how to solve the problem of untimely fire rescue in the fire alarm solution of the energy storage system has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0004] In view of this, the present application provides a fire extinguisher cabinet and an energy storage system to solve the problem of untimely fire rescue in the fire alarm solution of the energy storage system.

[0005] To achieve the above objectives, in the first aspect, this application provides the following technical solutions:

[0006] An energy storage system, comprising:

[0008] The fire alarm controller is in communication with each of the detection devices and is used to issue an alarm prompt containing fire location information when any of the detection devices detects a fire.

[0009] In some embodiments of the present application, the fire alarm controller is further configured to monitor the working status of each of the detection devices, and to issue an alarm including fault location information when any of the detection devices fails.

[0010] In some embodiments of the present application, each of the energy storage cabinets is provided with fire-fighting equipment, and the fire-fighting equipment is used to passively start and perform fire-fighting actions when a fire occurs in the energy storage cabinet.

[0011] In some embodiments of the present application, the fire-fighting equipment includes a fire bottle, a fire sprinkler, a solenoid valve, and a control circuit for controlling the opening and closing of the solenoid valve. The fire bottle is loaded with fire-extinguishing gas, and the fire sprinkler is connected to the fire-extinguishing gas output end of the fire bottle. The control circuit is provided with a temperature-sensing switch for sensing the temperature inside the energy storage cabinet. The temperature-sensing switch is provided on the fire sprinkler.

[0012] In some embodiments of the present application, the fire-fighting equipment further includes a gas cabinet disposed within the energy storage cabinet, the fire cylinder is disposed within the gas cabinet, and the fire-fighting nozzle is disposed on an outer cabinet wall of the gas cabinet.

In actual use, this energy storage system communicates with the detection devices in each energy storage cabinet through the fire alarm controller. The detection devices for detecting fires are addressable detection devices. Therefore, the fire alarm controller can know the location of each detection device. When any detection device detects a fire, the fire alarm controller can issue an alarm containing fire location information, thereby accurately determining the fire location, that is, the specific energy storage cabinet or cabinets in which the fire occurred. This eliminates the need for on-site inspections to determine the specific location of the fire, saves time in determining the specific location of the fire, makes it easier for users to respond to fires in a timely manner, and effectively reduces the probability of untimely fire rescue.

Since the fire extinguisher cabinet and the aforementioned energy storage system belong to the same general inventive concept and share a common core inventive concept, the fire extinguisher cabinet should also have the technical effects of the aforementioned energy storage system, which will not be elaborated on here.

[0018] In some embodiments of the present application, the external interface further includes at least one of the second communication interface, the third communication interface, the fourth communication interface, and the fifth communication interface;

[0047] The core of this application is to provide a fire extinguisher cabinet and an energy storage system to solve the problem of untimely fire rescue in the fire alarm solution of the energy storage system.

[0048] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0049] To meet the fire protection design requirements of energy storage systems, they must have fire alarm functionality. The current fire alarm solution involves installing dry contact smoke and temperature sensors within the energy storage cabinet for detection, directly uploading dry contact alarm information to the BMS. This fire protection solution has some drawbacks. For example, the BMS, using dry contact smoke and temperature detectors, cannot distinguish between alarms originating from specific smoke or temperature sensors. When a fire occurs in the energy storage system, users, upon receiving the fire alarm, need to conduct further on-site inspections to determine the specific cabinet location where the fire has occurred, and then extinguish the fire at that location. However, this process of inspecting and locating the fire can take time, and during this time, there is a risk that the fire at that location may spread, ultimately leading to delayed fire response.

[0050] In order to solve the problem that the fire alarm scheme of the energy storage system is not able to provide timely fire rescue, the present application provides an energy storage system in the embodiment of the first aspect, referring to Figure 1 As shown, it includes an energy storage cabinet 1 and a fire alarm controller 30.

[0051] The energy storage cabinet 1 is loaded with an energy storage device 11, such as an energy storage battery pack, etc., and in order to meet the requirements of energy storage power and capacity, the energy storage system can specifically include multiple (that is, two or more) energy storage cabinets 1, and each energy storage cabinet 1 is provided with an addressable detection device 2, the detection device 2 is used to detect fire, wherein the detection device 2 can specifically include an addressable smoke detector 21, can also include an addressable temperature detector 22, or can include both an addressable smoke detector 21 and an addressable temperature detector 22. Specifically, the temperature detector 21 can be an addressable smoke detector 21 or an addressable temperature detector 22. Specifically, the smoke detector 22 can detect a fire by monitoring a temperature exceeding a set value (e.g., 80°C). The smoke detector 21 can utilize air ionization or photoelectric detection. Air ionization detects smoke by detecting changes in the equilibrium between internal and external ionization chambers, or by sensing changes in light intensity with a photosensitive element. This method is very effective for detecting the combustion of common combustible materials. Photoelectric detection responds to solid or liquid particles suspended in the atmosphere produced by combustion or pyrolysis, detecting smoke by sensing changes in light intensity with a photosensitive element. Of course, it is understood that other addressable fire detectors can also be used in actual applications, such as flame detectors, which detect fires by responding to electromagnetic radiation emitted by flames in a specific wavelength band. This method primarily detects optical radiation produced by flames. Another example is optical radiation detectors, which primarily utilize optical radiation or flame radiation and respond to electromagnetic radiation emitted by flames in a specific wavelength band. Another example is combustible gas detection, which detects gases produced by combustion or pyrolysis and is used to detect specific gases produced in fires. These methods each have their own unique characteristics and varying scopes of application, but they are all widely used fire detection methods that help detect and respond to fires promptly. In practical applications, the method of choice can be tailored to your specific needs, and no further specific limitations are provided here.

[0052] It is worth mentioning that the addressable fire detector not only has the function of detecting fire, but also can feedback location information, that is, when a fire is detected, it will feedback fire signal and location signal.

[0053] In addition, the fire alarm controller 30 is communicatively connected with each detection device 2 (the specific connection method can be but is not limited to using a signal line to establish a communication connection). Since the detection device 2 uses an addressable detection device 20, the fire alarm controller 30 can obtain the location of each of the detection devices, and then when any detection device 2 detects a fire, the fire alarm controller 30 can issue an alarm prompt containing fire location information.

[0054] In actual application, this energy storage system communicates with the detection devices 2 in each energy storage cabinet 1 through a fire alarm controller 30. The detection devices 2 used to detect fire are addressable detection devices 2. Therefore, the fire alarm controller 30 can know the location of each of the detection devices 2. When any detection device 2 detects a fire, the fire alarm controller 30 can issue an alarm prompt containing fire location information, thereby accurately knowing the fire location, that is, knowing which specific energy storage cabinet or cabinets have a fire. There is no need to conduct on-site inspections to determine the specific location of the fire, which saves time in determining the specific location of the fire, makes it easier for users to respond to fires in a timely manner, and effectively reduces the probability of untimely fire rescue.

[0055] In some specific embodiments, wherein, with reference to Figure 1 The fire alarm controller 30 can be specifically connected to the detection device 2 for communication via a signal line, and then the fire alarm controller 30 can also be used to monitor the working status of each detection device 2, and when any detection device 2 fails, it issues an alarm prompt containing fault location information, so that the fire alarm controller 30 can not only issue an alarm prompt for the fire and the specific location of the fire, but also when the detection device 2 fails, for example, the detection device 2 cannot normally feedback the signal and is in a signal interruption state, it indicates that the detection device 2 has failed. At this time, even if the fire alarm controller 30 cannot issue a fire alarm, it does not affect the fire alarm controller 30 from issuing a fault alarm, thus avoiding the problem of being unable to issue an alarm prompt.

[0056] In some other specific embodiments, referring to Figure 1 As shown, each energy storage cabinet 1 may be provided with a fire-fighting device 4, which is used to passively activate and perform fire-fighting actions when a fire occurs in the energy storage cabinet 1. By designing the fire-fighting device 4, a fire in the energy storage cabinet 1 can be automatically extinguished, thereby better meeting fire protection standards.

[0057] It's worth noting that passive and active activation are two contrasting concepts. Active activation requires human intervention, such as pressing a button. Passive activation relies on advanced technologies such as sensors, signal processing, and automated control to automatically trigger and activate the firefighting equipment. Firefighting equipment using passive activation requires no human intervention and automatically executes its actions based on pre-set rules and logic.

[0058] In a further embodiment, referring to Figure 2As shown, the firefighting equipment 4 may include a fire cylinder 41, a fire sprinkler 42, a solenoid valve 43, and a control circuit 44 for controlling the opening and closing of the solenoid valve 43. The fire cylinder 41 is loaded with fire extinguishing gas, which may be, but is not limited to, a gas cylinder. The fire sprinkler 42 is connected to the fire extinguishing gas output end of the fire cylinder 41, specifically via a connecting pipe, which may be a flexible or rigid pipe. The control circuit 44 is provided with a temperature-sensing switch for sensing the temperature within the energy storage cabinet 1. When the temperature sensed by the temperature-sensing switch reaches a preset temperature, the control circuit 44 is turned on to control the opening of the solenoid valve 43, thereby enabling the fire sprinkler 42 to spray the fire extinguishing gas. By designing the firefighting equipment 4 with the solenoid valve 43 in conjunction with the control circuit 44, the opening control of the firefighting equipment 4 is more stable and reliable than the traditional fire sprinkler design method of bursting the temperature-sensing glass bulb.

[0059] In a further embodiment, the temperature-sensing switch can be specifically installed on the fire sprinkler 42. For example, the fire sprinkler 42 is designed with a fuse switch. When the temperature reaches a certain condition, such as 80°C, the fuse switch automatically melts, thereby triggering the control circuit 44 to conduct and control the opening of the solenoid valve 43, thereby fully flooding the pure energy storage cabinet 1 with gas to extinguish the fire. Of course, it is understood that in addition to being designed on the fire sprinkler 42, the temperature-sensing switch can be designed in other locations as long as it can achieve the function of a temperature-sensing switch. For example, it can be designed on the cabinet wall of the energy storage cabinet 1, or in the gas cabinet 40 designed within the energy storage cabinet 1 mentioned below.

[0060] In some other specific embodiments, referring to Figure 1 Combine Figure 2 As shown, the firefighting equipment 4 may further include a gas cabinet 40 disposed within the energy storage cabinet 1, a fire cylinder 41 disposed within the gas cabinet 40, and a fire sprinkler 42 disposed on the outer wall of the gas cabinet 40. The design of the gas cabinet 40 enables the entire firefighting equipment 4 to form a modular structure, making it more convenient to arrange.

[0061] In a further embodiment, referring to Figure 2As shown, the gas cabinet 40 may also be provided with a fire alarm output port 45 on its outer wall. This fire alarm output port 45 is communicatively connected to external equipment (e.g., the fire alarm controller 30 or the battery manager) within the energy storage cabinet 1, and is used to output a fire alarm signal to the external equipment (e.g., the fire alarm controller 30 or the battery manager) when the fire-fighting equipment 4 executes a firefighting action. The design of this fire alarm output port 45 ensures that fire information is promptly transmitted to the corresponding control terminal. For example, if the detection device 2 connected to the fire alarm controller 30 malfunctions and is unable to properly issue a fire alarm, connecting this fire alarm output port 45 to the fire alarm controller 30 can effectively prevent this problem. Specifically, the fire alarm output port 45 can be connected to the control circuit 44 of the fire-fighting equipment 4. When the control circuit 44 is turned on, the fire alarm output port 45 triggers and outputs a fire alarm signal. Alternatively, the fire alarm output port 45 can be connected to other relevant components of the fire-fighting equipment 4 that can detect the occurrence of a fire, such as the pressure gauge 46 designed on the outer cabinet wall of the gas cabinet 40 mentioned below. When the pressure gauge 46 reaches a preset pressure, the fire alarm output port 45 triggers and outputs a fire alarm signal. Alternatively, the fire alarm output port 45 can be connected to a corresponding temperature sensing component. When the temperature sensed by the temperature sensing component reaches a set condition, the fire alarm output port 45 triggers and outputs a fire alarm signal. In actual application, the triggering method of the fire alarm output port 45 can be selected according to actual needs, and no further specific limitation is given here.

[0062] In some specific embodiments, reference Figure 2 As shown, the outer wall of the gas cabinet 40 may also be provided with a pressure gauge 46 and a fault output port 47. The pressure gauge 46 is used to monitor the pressure information within the energy storage cabinet 1. The fault output port 47 can obtain pressure information from the pressure gauge 46 and communicate with external equipment (e.g., the fire alarm controller 30 or the battery manager) of the energy storage cabinet 1. This port is used to output a fault signal to the external equipment (e.g., the fire alarm controller 30 or the battery manager) when the obtained pressure information is abnormal. The design of the fault output port 47 ensures that fault information is promptly transmitted to the corresponding control terminal. Specifically, the fault output port 47 can detect a fault in the fire-fighting equipment 4 by, for example, the pressure gauge significantly exceeding a preset pressure range. Alternatively, the fault output port 47 can be connected to the control circuit 44, the solenoid valve 43, or the temperature switch. When the pressure on the pressure gauge 46 remains outside the preset range for a certain period of time while the control circuit 44 is on, the solenoid valve 43 is open, or the temperature switch is on, the fault output port 47 triggers the output of a fault signal.

[0063] It should be noted that the aforementioned external equipment specifically refers to related equipment outside the energy storage cabinet 1, such as a fire alarm controller 30 or a battery manager.

[0064] In some other specific embodiments, referring to Figure 1 As shown, each energy storage cabinet 1 can also be provided with a combustible gas detector 5 and an air intake and exhaust device 6. Each combustible gas detector 5 is communicatively connected to the fire alarm controller 30, for example, it can be connected through but not limited to a CAN communication line. The combustible gas detector 5 is dry-contact connected to the air intake and exhaust device 6 to control the start and stop of the air intake and exhaust device 6. Specifically, when the concentration of the combustible gas detected by the combustible gas detector 5 reaches a preset concentration, the air intake and exhaust device 6 is controlled to open.

[0065] In addition, refer to Figure 1 As shown, each energy storage cabinet 1 may also be provided with a smoke concentration display screen, and each smoke concentration display screen is communicatively connected to the fire alarm controller 30, for example, but not limited to, by a 485 communication line. This allows the user to promptly learn of the fire situation in the energy storage cabinet 1 through the smoke concentration display screen, and then make relevant fire prevention preparations in advance.

[0066] In some specific embodiments, reference Figure 1 As shown, the fire alarm controller 30 may also be provided with a display 301, which is used to display the detection information of each detection device 2. For example, through the display 301, it is possible to more intuitively know which specific energy storage cabinet or cabinets 1 have detected a fire, thereby enabling users to take more timely and effective response measures.

[0067] In some specific embodiments, reference Figure 1 As shown, the energy storage cabinet may further include a fire cabinet 3, wherein a fire alarm controller 30 is disposed in the fire cabinet 3. The fire cabinet 3 is designed to provide good protection for the fire alarm controller 30.

[0068] On the other hand, the embodiment of the present application also provides a fire extinguisher cabinet, specifically including a cabinet body 31 and a fire alarm controller 30 disposed in the cabinet body 31. The fire alarm controller 30 is provided with an external interface, and the external interface includes at least a first communication interface, the first communication interface being used to communicate with the detection device 2 in each energy storage cabinet body 1 of the energy storage system. For example, the first communication interface is connected to the detection device 2 in each energy storage cabinet body 1 via a signal line, wherein the detection device 2 is used to detect fire and is an addressable detection device 2. The fire alarm controller 30 is used to issue an alarm prompt containing fire location information when any detection device 2 detects a fire. Since the fire extinguisher cabinet and the aforementioned energy storage system belong to the same general inventive concept and have a common core inventive concept, the fire extinguisher cabinet should also have the technical effects of the aforementioned energy storage system, which will not be described in detail here.

[0069] In a further implementation scheme, the above-mentioned external interface may also include at least one of the four communication interfaces of a second communication interface, a third communication interface, a fourth communication interface and a fifth communication interface; wherein the second communication interface is used to communicate and connect with the combustible gas detector 5 in each energy storage cabinet, specifically but not limited to using a CAN communication line connection; the third communication interface is used to connect with the station-level fire host, so that the fire alarm controller 30 can send relevant fire signals to the station-level fire host in a timely manner; the fourth communication interface is used to communicate and connect with the concentration display screen 7 in each energy storage cabinet 1, specifically but not limited to using a 485 communication line connection; the fifth communication interface is used to communicate and connect with the base station controller, so that the fire alarm controller 30 can send relevant fire signals to the base station controller in a timely manner, making it more convenient for users to understand relevant situations.

[0070] In addition, the external interfaces may also include active node output interfaces and / or passive node output interfaces. The active node output interfaces are used to communicate with the solenoid valve 43 of the firefighting equipment 4 within the energy storage cabinet 1 to control the opening and closing of the solenoid valve 43. The passive node output interfaces are used to communicate with the air intake and exhaust device 6 within the energy storage cabinet 1 to control the activation of the fan of the air intake and exhaust device 6. By designing these external interfaces, the fire alarm controller 30 within the fire cabinet has more functions.

[0071] It should also be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same and similar parts between the various embodiments can be referenced to each other.
