Description

Technical Field

[0001] This utility model relates to the field of fire protection system technology, specifically to a fire protection system and energy storage cabinet. Background Technology

[0002] Energy storage power stations are established to regulate peak and off-peak electricity demand. Simply put, they store excess electricity during off-peak hours and release it back into the grid during peak hours to achieve peak shaving, valley filling, voltage regulation, and frequency regulation. Energy storage power stations typically consist of several battery compartments, each composed of several battery clusters, and each battery cluster is composed of several battery packs connected in series.

[0003] With the rapid development of energy storage technology, energy storage power stations are becoming increasingly large-scale, and with the rapid development of the energy storage industry, energy storage power stations have been widely used. However, because the charging and discharging process of batteries generates a large amount of heat, fires and explosions at energy storage power stations occur frequently. Therefore, it is necessary to install fire protection systems within energy storage power stations to deal with fires.

[0004] Because energy storage power stations occupy a large area, the battery fire suppression systems provided in related technologies are slow to assess the occurrence of fires and often only activate when an open flame is detected. Even if the fire is extinguished, the damage to the energy storage power station is still significant, resulting in low fire suppression efficiency. Utility Model Content

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 scope of protection of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. In the present utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0041] Reference Figure 1 and Figure 2 The first aspect of this utility model provides a fire protection system 1, which is installed in a battery compartment 2. The battery compartment 2 includes a compartment body 21 and a battery pack 22 installed in the compartment body 21. The fire protection system 1 includes a fire extinguishing device 11, a first pipeline 12, and an aspirating detector 13. The fire extinguishing device 11 is used to output a fire extinguishing agent. The inlet of the first pipeline 12 is connected to the fire extinguishing device 11, and the outlet of the first pipeline 12 is used to connect to the battery pack 22 to output the fire extinguishing agent into the battery pack 22. The aspirating detector 13 is connected to the first pipeline 12 to monitor the gas in the battery pack 22 through the first pipeline 12, and the aspirating detector 13 is communicatively connected to the fire extinguishing device 11.

[0042] As a core component of the fire protection system 1, the fire extinguishing device 11 is mainly used to store and deliver fire extinguishing agents. When an abnormal situation such as a fire occurs in the battery pack 22, it can promptly provide the medium required for fire extinguishing. The type of fire extinguishing agent can be selected as needed. For example, it can be dry powder fire extinguishing agent, carbon dioxide fire extinguishing agent, perfluorohexanone, etc. Delivering the fire extinguishing agent to the fire location can effectively suppress the spread of fire, reduce the losses caused by the fire, and protect the safety of the entire battery compartment 2.

[0043] The first pipeline 12 acts as a bridge connecting the fire extinguishing device 11 and the battery pack 22, responsible for delivering the extinguishing agent output from the fire extinguishing device 11 into the battery pack 22, and simultaneously providing a channel for the aspirating detector 13 to monitor the gas inside the battery pack 22. The inlet of the first pipeline 12 is connected to the fire extinguishing device 11 to ensure the extinguishing agent can flow smoothly into the first pipeline 12; the outlet is connected to the inside of the battery pack 22, allowing the extinguishing agent to accurately enter the battery pack 22, achieving precise fire extinguishing of the battery pack 22.

[0044] The aspirating detector 13 actively extracts and analyzes air samples from the battery pack 22 through the first pipe 12. Unlike traditional point detectors that can only passively wait for smoke to spread to the vicinity of the point detector, the active detection method of the aspirating detector 13 makes it unrestricted by air flow and smoke diffusion path, and can obtain air information in the battery pack 22 more quickly, thereby quickly determining whether there is a temperature abnormality in the battery pack 22 and achieving rapid fire prevention.

[0045] Specifically, during normal operation of the battery compartment 2, the aspirating detector 13 continuously monitors the gas inside the battery pack 22 through the first pipeline 12, including detecting the concentration of gases such as carbon monoxide, hydrogen, and smoke, and uses this to determine whether the battery pack 22 is operating normally. If the concentrations of various gases are within the normal range, the fire extinguishing device 11 remains in standby mode. If the concentrations of various gases exceed preset thresholds, such as carbon monoxide exceeding 800 ppm, hydrogen exceeding 500 ppm, or the AD value of smoke exceeding 1100, it indicates that the battery pack 22 has malfunctioned. At this time, the fire extinguishing device 11 can be activated, and fire extinguishing agent can be output into the battery pack 22 through the first pipeline 12 to quickly suppress the fire.

[0046] In this embodiment of the invention, the aspirating detector 13 actively extracts and detects gas within the battery pack 22, enabling real-time active monitoring of the battery pack 22's operational status. This allows for the detection of anomalies at the very early stages of a fire, significantly improving the timeliness and accuracy of early warnings. Furthermore, the aspirating detector 13 shares the first conduit 12 with the fire extinguishing device 11, simplifying the structure of the fire protection system 1 while ensuring its normal operation. This avoids occupying excessive internal space in the battery compartment 2, reduces the installation difficulty and cost of the fire protection system 1, and expands its applicability.

[0047] In one embodiment, reference is made to Figure 1 and Figure 2 The first conduit 12 has multiple outlets, at least some of which are used to connect to different battery packs 22.

[0048] Since the battery compartment 2 often contains multiple battery packs 22, the probability and timing of malfunctions vary among different battery packs 22 due to individual differences and usage conditions. Therefore, this embodiment utilizes at least some outlets to connect to different battery packs 22, enabling simultaneous monitoring and protection of multiple battery packs 22. Multiple outlets ensure that the extinguishing agent output by the fire extinguishing device 11 is accurately and efficiently delivered to the burning battery pack 22, greatly enhancing the targeting of the fire protection system 1 and thus effectively improving the safety of the battery compartment 2.

[0049] In some alternative implementations, in order to accurately identify which battery pack 22 is on fire, multiple aspirating detectors 13 can be set up, each aspirating detector 13 monitoring a different battery pack 22, thereby enabling the fire extinguishing device 11 to accurately deliver the extinguishing agent to the battery pack 22 that is in an abnormal situation, and to achieve precise control of the fire.

[0050] In some alternative embodiments, the number of outlets of the first pipeline 12 may be the same as the number of battery packs 22, with each outlet corresponding to a battery pack 22. This allows the fire extinguishing device 11 to deliver the fire extinguishing agent to each battery pack 22 through the first pipeline 12, preventing any leakage and thus providing more comprehensive protection for the battery compartment 2.

[0051] In one embodiment, reference is made to Figure 1 and Figure 2 The fire protection system 1 also includes multiple first control valves 14, with at least one first control valve 14 provided for each outlet. The first control valve 14 is used to control the opening and closing of the corresponding outlet.

[0052] By setting the first control valve 14, users can flexibly adjust the monitoring frequency of different battery packs 22 according to actual needs. For example, when multiple aspirating detectors 13 are used to monitor different battery packs 22, if the battery compartment 2 is operating normally and the status of each battery pack 22 is stable, the control valves corresponding to the outlets of some low-risk areas can be closed to reduce the monitoring workload of the aspirating detectors 13 corresponding to those battery packs 22. When using a single aspirating detector 13, closing some control valves can also reduce the aspirating volume of the aspirating detector 13, thereby reducing the workload of the aspirating component in the aspirating detector 13. Furthermore, the aspirating detector 13 can concentrate limited detection resources on fewer gas samples, thereby more accurately analyzing gas composition, identifying abnormal parameters in the gas, and improving the detection accuracy of the battery pack 22. If a fire is detected in a battery pack 22, the first valve installed in that battery pack 22 can be opened, and the first valves installed in other battery packs 22 can be closed. This ensures that the extinguishing agent output by the fire extinguishing device 11 is delivered to the burning battery pack 22 in a concentrated and efficient manner, avoiding waste of extinguishing agent and enhancing the fire extinguishing effect.

[0053] In one embodiment, reference is made to Figure 1 and Figure 2 The first pipeline 12 includes a main pipeline 121 and multiple branch pipelines 122. One end of the main pipeline 121 is connected to the fire extinguishing device 11 to form the inlet of the first pipeline 12. One end of each branch pipeline 122 is connected to the main pipeline 121, and the other end forms an outlet for connecting to the inside of the battery pack 22. The aspirating detector 13 is connected to the main pipeline 121.

[0054] The aspirating detector 13 is connected to the main pipeline 121, and the main pipeline 121 is connected to the inside of the battery pack 22 through multiple branch pipelines 122, so that the aspirating detector 13 can obtain comprehensive information of gas samples from multiple battery packs 22, and fully grasp the gas status inside the entire battery compartment 2, thereby improving the detection efficiency of abnormal situations.

[0055] In some optional embodiments, a temperature sensor can be installed at the outlet of each branch pipe 122 to monitor the temperature inside the battery pack 22, allowing the aspirating detector 13 and the temperature sensor to corroborate each other and improve detection accuracy. If the aspirating detector 13 and the temperature sensor simultaneously detect an abnormality, it can be determined that a fire has occurred in the battery compartment 2. By obtaining the location of the temperature sensor, the specific battery pack 22 where the fire occurred can be accurately identified, thereby achieving precise fire suppression.

[0056] In one embodiment, reference is made to Figure 3 and Figure 4 The fire protection system 1 also includes a second pipe 15, one end of which is connected to the fire extinguishing device 11, and the other end of which can be connected to the chamber 21, so that the fire extinguishing device 11 can output fire extinguishing agent into the chamber 21 through the second pipe 15.

[0057] Because a fire in the battery pack 22 could potentially spread to other parts of the compartment 21, this embodiment of the invention includes a second conduit 15 to prevent electrical fires within the entire compartment 21. One end of the second conduit 15 is tightly connected to the fire extinguishing device 11, and the other end is connected to the compartment 21. This allows the fire extinguishing device 11 to not only accurately deliver the extinguishing agent to the battery pack 22 via the first conduit 12, but also to output the extinguishing agent to the entire compartment 21 via the second conduit 15 when a fire hazard occurs in the battery compartment 2. This effectively prevents the fire from spreading from the battery pack 22 to the space within the compartment 21, enhancing the fire protection system 1's ability to respond to different fire scenarios and improving the safety and reliability of the battery compartment 2.

[0058] In some alternative implementations, the first conduit 12 is connected to the second conduit 15, thereby reducing the number of interfaces required for the fire extinguishing device 11. In this case, the aspirating detector 13 should be located downstream of the connection between the first conduit 12 and the second conduit 15 to prevent the aspirating detector 13 from drawing in and detecting gas in the battery compartment 2.

[0059] In one embodiment, reference is made to Figures 2 to 4 The fire protection system 1 also includes a composite detector 16, which is installed inside the compartment 21 to detect gas inside the compartment 21 and outside the battery pack 22; the composite detector 16 is communicatively connected to the fire extinguishing device 11.

[0060] The composite detector 16 is communicatively connected to the fire extinguishing device 11. Once it detects that the gas parameters outside the battery pack 22 inside the compartment 21 exceed the normal range and reach a preset threshold, it will immediately send a signal to the fire extinguishing device 11, prompting the fire extinguishing device 11 to take corresponding measures according to the actual situation. The composite detector 16 can integrate various types of sensors, such as smoke sensors, temperature sensors, and carbon monoxide sensors, to comprehensively monitor the gas environment outside the battery pack 22. This embodiment of the invention, by setting up the composite detector 16, improves the fire protection system 1's ability to monitor and respond to other locations within the compartment 21, allowing the fire extinguishing device 11 to comprehensively protect the fire safety of the battery compartment 2 through the first pipe 12 and the second pipe 15, further enhancing the reliability and stability of the fire protection system 1.

[0061] In one embodiment, reference is made to Figure 3 and Figure 4 The fire protection system 1 also includes a second control valve 17, which is installed in the second pipeline 15 and is used to control the opening and closing of the second pipeline 15.

[0062] By setting a second control valve 17, the user can extinguish the fire in the battery compartment 2. For example, when the composite detector 16 detects an anomaly in the battery compartment 2, the second control valve 17 can be opened, allowing the fire extinguishing device 11 to deliver the extinguishing agent into the battery compartment 2; otherwise, the second control valve 17 is kept closed to reduce the impact of the second pipeline 15 on the first pipeline 12, ensuring that the extinguishing agent output by the fire extinguishing device 11 is delivered to the burning battery pack 22 in a concentrated and efficient manner, avoiding waste of the extinguishing agent.

[0063] In one embodiment, reference is made to Figure 2 and Figure 5 The fire protection system 1 also includes an alarm device 18, which is communicatively connected to the aspirating detector 13 and is used to issue an alarm.

[0064] Alarm device 18 can be of various types and can be configured according to actual needs. For example, alarm device 18 can be an audible and visual alarm. When the aspirating detector 13 detects an abnormality, it can attract the attention of staff through a loud sound and a conspicuous light, making it easier for staff to notice in time. Alarm device 18 can also include a wireless communication mechanism, using wireless communication technologies such as Bluetooth, Wi-Fi, or mobile networks to send alarm information to remote terminal devices, such as staff's mobile phones or computers in the monitoring center, so that staff can remotely understand the abnormal situation of battery compartment 2 and make timely decisions, thereby improving the safety of battery compartment 2.

[0065] This embodiment of the utility model, by setting up an alarm device 18, enables the aspirating detector 13 to detect abnormal situations and provide timely feedback through the alarm device 18, thereby quickly and effectively transmitting abnormal information to relevant personnel and equipment, and improving the overall efficiency of the fire protection system 1.

[0066] In one embodiment, reference is made to Figure 2 and Figure 5 The fire protection system 1 also includes a control device 19, which is communicatively connected to the aspirating detector 13 and the fire extinguishing device 11, respectively. The control device 19 can control the opening and closing of the fire extinguishing device 11.

[0067] The control device 19 establishes communication connections with both the aspirating detector 13 and the fire extinguishing device 11. The aspirating detector 13 continuously monitors the gas conditions inside the battery pack 22. Once it detects abnormalities in parameters such as gas composition and concentration, exceeding preset safety thresholds, it immediately transmits a signal to the control device 19. Upon receiving the abnormal signal from the aspirating detector 13, the control device 19 quickly analyzes and judges the situation according to its internal preset logic program. If it determines that the abnormal situation has reached the level requiring the activation of fire extinguishing measures, the control device 19 immediately sends an activation command to the fire extinguishing device 11, precisely controlling the activation of the fire extinguishing device 11 to deliver the extinguishing agent into the battery pack 22 through the first pipeline 12, thus promptly suppressing the fire. When the fire is extinguished, and the aspirating detector 13 detects that the gas parameters inside the battery pack 22 have returned to normal, it sends a signal back to the control device 19. The control device 19 then issues a shutdown command to shut down the fire extinguishing device 11, avoiding unnecessary waste of the extinguishing agent.

[0068] By setting up control device 19, the workflow of fire protection system 1 is optimized, the intelligence level of fire protection system 1 is improved, and the ability of fire protection system 1 to deal with fire hazards in battery compartment 2 is enhanced, thereby ensuring the safe and stable operation of battery compartment 2.

[0069] In one embodiment, reference is made to Figure 5The control device 19 includes multiple communication interfaces and multiple dry contact interfaces. The control device 19 is connected to the aspirating detector 13 and the fire extinguishing device 11 through the communication interfaces.

[0070] The communication interface may include two sets of CAN interfaces and three sets of 485 communication interfaces, thereby facilitating the control device 19 to connect to more signal sources; three or more dry contact interfaces may be provided for connecting switch signals, facilitating the connection of the control device 19 with other structures within the fire protection system 1 to achieve the opening and closing control of other structures. It is understood that the control device 19 may also be provided with a power supply interface, a program programming interface, or a detection interface; this embodiment of the present invention does not impose any limitations on this.

[0071] According to a second aspect of the present invention, an energy storage cabinet is provided, with reference to... Figure 3 The energy storage cabinet includes a battery compartment 2 and the fire protection system 1 described in the previous embodiment. The battery compartment 2 includes a housing 21 and a battery pack 22 disposed within the housing 21. The fire protection system 1 is disposed within the battery compartment 2, and the outlet of the first pipeline 12 is connected to the battery pack 22. Since the energy storage cabinet includes the aforementioned fire protection system 1, it possesses all the beneficial effects of the aforementioned fire protection system 1. Further details of this embodiment will not be elaborated upon here.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model.
