[0022] The battery compartment, equipment compartment, and battery pack inside the energy storage container pose a fire risk during operation, especially fires caused by battery thermal runaway. Once a fire occurs, the consequences are unimaginable, causing not only significant environmental damage and property loss, but also potentially triggering a chain reaction that leads to secondary reignition or even explosion. Due to the complexity of battery fire mechanisms, traditional fire extinguishing methods are insufficient to meet the fire protection requirements for battery fires, making reignition a common occurrence.

[0023] Based on this, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4As shown in the figure, this application embodiment provides an energy storage container 1, including fire-fighting pipeline 2 and control components 3; wherein, the energy storage container 1 has a sealed battery compartment 11 and an equipment compartment 12, and the battery compartment 11 is used to house battery units 5. It can be understood that the battery compartment 11 and the equipment compartment 12 are both sealed, so that they form an effective sealed isolation from the external environment, and the battery compartment 11 and the equipment compartment 12 are also sealed and isolated from each other (the energy storage container 1 is designed for A60 and IP67); the sealed isolation between the battery compartment 11 and the equipment compartment 12, as well as the sealed isolation between the battery compartment 11 and the equipment compartment 12 and the external environment, can effectively prevent the spread of fire and limit the fire to a specific area, which facilitates the energy storage container 1 to carry out efficient and rapid fire extinguishing.

[0024] In this embodiment, the fire-fighting pipeline 2 is located in the battery compartment 11 and / or the equipment compartment 12, and the fire-fighting pipeline 2 is connected to at least one of the battery compartment 11, the equipment compartment 12, and the battery unit 5. That is, the fire-fighting pipeline 2 can be connected to the battery compartment 11, the equipment compartment 12, the battery unit 5, or all of the battery compartment 11, the equipment compartment 12, and the battery unit 5. Preferably, in this solution, connecting the fire-fighting pipeline 2 to the battery compartment 11, the equipment compartment 12, and the battery unit 5 can achieve targeted and efficient fire extinguishing of the battery compartment 11, the equipment compartment 12, and the battery unit 5, thereby improving the fire extinguishing effect of the energy storage container 1.

[0025] In this embodiment, the control component 3 has an inlet end and an outlet end, wherein the inlet end is connected to a fire-fighting medium delivery system, and the outlet end is connected to the aforementioned fire-fighting pipeline 2. The control component 3 is configured to deliver fire-fighting medium (water or extinguishing agent) to the battery compartment 11 and / or equipment compartment 12 and / or battery unit 5 that generated the alarm when at least one of the battery compartment 11, equipment compartment 12, and battery unit 5 generates a fire alarm through the fire-fighting pipeline 2. Since the battery compartment 11, equipment compartment 12, battery unit 5, and the external environment of the enclosure are all sealed and isolated, when the fire-fighting medium is delivered to the battery compartment 11, equipment compartment 12, and battery unit 5, the battery unit 5 in the battery compartment 11 is completely submerged in the fire-fighting medium, the various electrical equipment in the equipment compartment 12 is submerged in the fire-fighting medium, and the battery cells and other structures in the battery unit 5 are submerged in the fire-fighting medium, thereby achieving an immersion fire extinguishing effect. Moreover, the fire-fighting medium can continuously cool the battery and equipment after the fire is extinguished, ensuring that the temperature remains within a safe range and preventing reignition.

[0026] In this embodiment, by completely immersing the battery cells and other structures in the battery unit 5, the fire-fighting medium can isolate oxygen, prevent thermal runaway reaction in the battery unit 5, and prevent the fire from spreading; by completely immersing the battery units 5 in the battery compartment 11, the fire-fighting medium can isolate oxygen and block the fire transmission between two adjacent battery units 5; by completely immersing the electrical equipment in the equipment compartment 12, the fire-fighting medium can isolate oxygen and quickly block the fire and prevent the fire from spreading.

[0027] In this embodiment, the fire-fighting medium delivery system can deliver seawater, which is pumped in by a pump and introduced to the inlet, achieving fire extinguishing through the fire-fighting pipeline 2. Using seawater as the fire-fighting medium eliminates the need for additional fire-fighting water tanks on the ship, saving valuable shipboard space and reducing the weight of additional fire-fighting water, thus improving the ship's carrying capacity and fuel efficiency. Furthermore, the pumped seawater can be filtered before being delivered to the corresponding area for fire extinguishing, filtering out impurities and particulate matter to prevent pipe blockage. In addition, seawater contains a large amount of high-concentration salt and other minerals, which are highly corrosive and may corrode the metal components in the energy storage container 1, reducing the service life of the equipment. Filtration can reduce corrosion of pipelines and equipment such as the energy storage container 1.

[0028] In this embodiment, the control component 3 can be located in either the battery compartment 11 or the equipment compartment 12. Preferably, this solution places the control component 3 in the equipment compartment 12. When maintenance or repair is required, staff only need to open the panel of the equipment compartment 12 to perform the maintenance or repair. If the control component 3 is placed in the battery compartment 11, the panel of the battery compartment 11 also needs to be opened. Furthermore, the battery compartment 11 contains numerous high-voltage wiring harnesses. During maintenance or repair in the battery compartment 11, due to limited space and dense equipment, misoperation is prone to occur, leading to equipment damage or safety accidents, causing inconvenience for staff. The equipment compartment 12 typically houses various control and auxiliary equipment; placing the control component 3 in the equipment compartment 12 allows for better system integration and centralized management.

[0029] Reference Figure 1 , Figure 4As shown in one embodiment of this application, the energy storage container 1 further includes a detection component 4 and a controller. The detection component 4 is used to detect fire characteristics of at least one of the battery compartment 11, equipment compartment 12, and battery unit 5. The detection component 4 can be installed in the battery compartment 11, the equipment compartment 12, or the battery unit 5, or it can be installed in all three compartments. The controller is communicatively connected to the detection component 4. When at least one of the battery compartment 11, equipment compartment 12, and battery unit 5 generates a fire alarm, the controller controls the control component 3 to deliver fire-fighting media to the battery compartment 11 and / or equipment compartment 12 and / or battery unit 5 that generated the alarm via the fire-fighting pipeline 2. For example, the controller can be configured to control the control component 3 to selectively deliver fire-fighting media to the battery compartment 11, equipment compartment 12, and / or battery unit 5 that generated the fire alarm via the fire-fighting pipeline 2. For example, if a fire alarm originates from battery unit 5 and battery compartment 11, the controller controls control component 3 to deliver fire-fighting medium to battery compartment 11 and battery unit 5. As for equipment compartment 12, where no fire alarm has occurred, the controller controls control component 3 not to deliver fire-fighting medium to equipment compartment 12.

[0030] In this embodiment, the detection component 4 can detect temperature information, smoke information, or both in the battery compartment 11, equipment compartment 12, and battery unit 5. Based on this, the detection component 4 can be a smoke sensor, a temperature sensor, etc. The detection component 4 transmits the detected temperature and smoke information to the controller in real time. The controller can set corresponding alarm thresholds for the smoke sensor and temperature sensor. The controller uses the set alarm thresholds to determine whether there is a fire in the battery compartment 11, equipment compartment 12, and battery unit 5. When the preset alarm threshold is reached, the controller controls the control component 3 to deliver fire-fighting medium to the battery compartment 11 and / or equipment compartment 12 and / or battery unit 5 where the fire occurred through the fire-fighting pipeline 2, so as to achieve targeted fire extinguishing.

[0031] Reference Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 As shown in one embodiment of this application, the fire-fighting pipeline 2 includes a first branch pipe 21, a second branch pipe 22, and a third branch pipe 23; wherein the first branch pipe 21, the second branch pipe 22, and the third branch pipe 23 are respectively connected to the outlet end of the control component 3. According to the instructions of the controller, the control component 3 controls one, two, or three of the first branch pipe 21, the second branch pipe 22, and the third branch pipe 23 to be connected to the outlet end of the control component 3, so as to realize the delivery of fire-fighting medium to different branch pipes to achieve targeted fire extinguishing effect.

[0032] In this embodiment, the first branch pipe 21 is disposed inside the battery compartment 11, and at least a portion of the first branch pipe 21 extends from the battery compartment 11 into the equipment compartment 12 for connection to the outlet end of the control component 3, such as... Figure 4 As shown, the first branch pipe 21 located inside the battery compartment 11 has multiple first water outlets 211, which are used to deliver fire-fighting media into the battery compartment 11. It can be understood that the first branch pipe 21 located inside the battery compartment 11 is connected to the battery compartment 11 through the aforementioned multiple first water outlets 211. When a fire alarm occurs in the battery compartment 11, the controller controls the outlet end of the control component 3 to connect with the first branch pipe 21, and delivers the fire-fighting media in the first branch pipe 21 to the battery compartment 11 through the aforementioned multiple first water outlets 211 to achieve the effect of immersion fire extinguishing. The multiple first water outlets 211 can point in different directions to achieve the spraying and delivery of fire-fighting media in different directions. This design can ensure that the fire-fighting media can evenly and comprehensively cover all areas inside the battery compartment 11, thereby achieving a highly efficient fire extinguishing effect.

[0033] In this embodiment, the first water outlet 211 can be a nozzle, which can spray fire-fighting medium in the form of mist or column, and is suitable for scenarios that require rapid coverage of a large area.

[0034] In this embodiment, the first branch pipe 21 located inside the battery compartment 11 can be designed as a multi-branch structure, with multiple first water outlets 211 installed on each branch to ensure that the fire-fighting medium can be evenly distributed to various areas inside the battery compartment 11; or multiple first branch pipes 21 can be provided inside the battery compartment 11, thereby further optimizing the distribution and delivery efficiency of the fire-fighting medium. Multiple first branch pipes 21 can evenly distribute the fire-fighting medium to various areas inside the battery compartment 11 to achieve rapid fire extinguishing; the first branch pipe 21 can be located in the area between the top wall of the battery compartment 11 and the top of the battery unit 5, that is, in the area above the battery unit 5. By placing the first branch pipe 21 above the battery unit 5, it can be ensured that the fire-fighting medium is evenly sprayed to each battery unit 5 from above, achieving full coverage and reducing fire extinguishing dead spots; and appropriate fixing measures, such as brackets or buckles, are used to fix the first branch pipe 21 to the top wall of the battery compartment 11 to ensure the stability and safety of the first branch pipe 21.

[0035] In this embodiment, the second branch pipe 22 is located inside the equipment compartment 12, and the second branch pipe 22 is connected to the outlet end of the control component 3, such as... Figure 4As shown, the second branch pipe 22 located inside the equipment compartment 12 has multiple second water outlets 221, which are used to deliver fire-fighting media into the equipment compartment 12. It can be understood that the second branch pipe 22 located inside the equipment compartment 12 is connected to the equipment tank through the aforementioned multiple second water outlets 221. When a fire alarm occurs in the equipment compartment 12, the controller controls the outlet end of the control component 3 to connect with the second branch pipe 22, and delivers the fire-fighting media in the second branch pipe 22 to the equipment compartment 12 through the aforementioned multiple second water outlets 221, so as to achieve the effect of immersion fire extinguishing. The multiple second water outlets 221 can point in different directions to achieve the spraying and delivery of fire-fighting media in different directions. This design can ensure that the fire-fighting media can evenly and comprehensively cover all areas inside the equipment compartment 12, thereby achieving a highly efficient fire extinguishing effect.

[0036] In this embodiment, the second water outlet 221 can be a nozzle, which can spray fire-fighting medium in the form of mist or column, and is suitable for scenarios that require rapid coverage of a large area.

[0037] In this embodiment, the second branch pipe 22 located in the equipment compartment 12 can be designed as a multi-branch structure, with multiple second water outlets 221 installed on each branch to ensure that the fire-fighting medium can be evenly distributed to various areas within the battery compartment 11; or multiple second branch pipes 22 can be provided in the equipment compartment 12, thereby further optimizing the distribution and delivery efficiency of the fire-fighting medium. Multiple second branch pipes 22 can evenly distribute the fire-fighting medium to various areas within the equipment compartment 12, achieving rapid fire extinguishing; the second branch pipe 22 can be located in the area between the top wall of the equipment compartment 12 and the top of each electrical device, that is, in the area above the electrical devices. By placing the second branch pipe 22 above the electrical devices, it can be ensured that the fire-fighting medium is evenly sprayed onto each electrical device from above, achieving full coverage and reducing fire-fighting dead spots; and appropriate fixing measures, such as brackets or buckles, are used to fix the second branch pipe 22 to the top wall of the equipment compartment 12 to ensure the stability and safety of the second branch pipe 22.

[0038] In this embodiment, the third branch pipe 23 is disposed inside the battery compartment 11, and at least a portion of the third branch pipe 23 extends from the battery compartment 11 into the equipment compartment 12 for connection with the outlet end of the control component 3, such as... Figure 2 , Figure 3 As shown, the third branch pipe 23 located in the battery compartment 11 is connected to the battery unit 5 so that when a fire alarm occurs in the battery unit 5, the controller controls the outlet end of the control component 3 to connect with the third branch pipe 23 and deliver fire-fighting medium into the battery unit 5 to achieve targeted fire suppression.

[0039] Reference Figure 1 , Figure 2 , Figure 3As shown, in one embodiment of this application, the battery unit 5 includes multiple battery components 51, which are arranged sequentially along the length of the battery compartment 11; along the height of the battery compartment 11, the battery components 51 include multiple battery packs 511 arranged sequentially; the third branch pipe 23 includes a third main pipe 231, a third sub-pipe 232, and a sub-valve; wherein the third main pipe 231 extends from the equipment compartment 12 into the battery compartment 11, and the third main pipe 231 located in the equipment compartment 12 is connected to the outlet end of the control component 3, and multiple third sub-pipes 232 are respectively connected to the third main pipe 231 located in the battery compartment 11, such as... Figure 2 , Figure 3 As shown, the number of third sub-pipes 232 is matched with the number of battery packs 51, and each third sub-pipe 232 is provided with multiple sub-valves. The number of sub-valves on each third sub-pipe 232 is matched with the number of battery packs 511 contained in the battery pack 51 corresponding to that third sub-pipe 232. That is, the sub-valves are used to connect each battery pack 511 in the same battery pack 51 to the third sub-pipe 232 corresponding to that battery pack 51. By controlling the opening and closing of the sub-valves, the connection between the corresponding battery pack 511 and the third sub-pipe 232 can be controlled. Each sub-valves are communicatively connected to the controller.

[0040] In this embodiment, each battery pack 511 is equipped with a detection component 4, such as a smoke sensor, temperature sensor, or gas sensor, to detect the smoke, temperature, and harmful gas generation within each battery pack 511 (to more comprehensively monitor the operating status of the battery pack 511), and transmit the detected smoke and other information to the controller in real time. When the smoke and temperature parameters within a battery pack 511 reach a preset threshold, the controller controls the corresponding sub-valve to open, connecting the battery pack 511 to the third sub-pipeline 232. The controller then connects the third main pipeline 231 to the outlet of the control component 3, and delivers the fire-fighting medium to the corresponding battery pack 511 through the third sub-pipeline 232, ensuring the fire-fighting medium completely fills the battery pack 511 and completely submerges the battery cells and other structures within the battery pack 511, achieving a submersion fire extinguishing effect and effectively preventing reignition.

[0041] In this embodiment, the third sub-pipeline 232 and sub-valve configuration make fire suppression of battery pack 511 more targeted. When a fire is detected in a battery pack 511, the controller only opens the sub-valve corresponding to that battery pack 511. This allows for precise location of the battery pack 511 that is on fire and local fire suppression, reducing interference with other battery packs 511, avoiding unnecessary cooling and potential damage, and ensuring the stable operation of the entire energy storage system, thereby improving the overall reliability of the energy storage system.

[0042] In this embodiment, as Figure 2 , Figure 3 As shown, the third main pipe 231 can be arranged in the area between the bottom of the battery unit 5 and the bottom wall of the battery compartment 11 to make full use of the space inside the battery compartment 11; appropriate fixing measures, such as brackets or buckles, are used to fix the third branch pipe 23 (the third main pipe 231 and the third sub-pipe 232) to the bottom wall of the battery compartment 11 to ensure the stability and safety of the third branch pipe 23.

[0043] In this embodiment, the sub-valve can be located inside or outside the battery pack 511. The location of the sub-valve is not limited in this solution.

[0044] Reference Figure 5 , Figure 9 As shown, in one embodiment of this application, the control component 3 includes a liquid inlet main pipe 31 and a valve assembly 32; wherein, the liquid inlet main pipe 31 is disposed within the equipment compartment 12, as... Figure 5 As shown, at least a portion of the liquid inlet pipe 31 extends outward from the energy storage container 1, and one end of the liquid inlet pipe 31 extending outward from the energy storage container 1 forms an inlet end for connecting with the fire-fighting medium delivery system; the valve assembly 32 is connected to the liquid inlet pipe 31, and the outlet end is formed at the end of the valve assembly 32 away from the liquid inlet pipe 31.

[0045] In this embodiment, the valve assembly 32 is used to control the connection between the outlet end and any one, two, or three of the first branch pipe 21, the second branch pipe 22, and the third branch pipe 23. This enables the controller to connect the outlet end of the valve assembly 32 to the pipeline corresponding to the battery compartment 11, the equipment compartment 12, and the battery pack 511 in the battery unit 5 when the detection assembly 4 detects a fire alarm. This allows for targeted fire suppression.

[0046] In this embodiment, the liquid inlet main pipe 31 extends outward from one end of the energy storage container 1 (i.e., the inlet end) and uses a drip-free quick-connect plug for quick connection and disconnection of the pipeline. This ensures that no liquid leakage occurs during connection and disconnection. In other words, when the quick-connect plug is disconnected, the water in the original pipeline will not flow out. The quick-connect plug itself will shut off the water circuit, avoiding the need to purge the air from the pipeline and refill it with water every time it is reconnected. Furthermore, the drip-free quick-connect plug can quickly connect and disconnect the liquid inlet main pipe 31 and the fire-fighting medium delivery system, improving the efficiency of maintenance and inspection.

[0047] Reference Figure 9As shown, in one embodiment of this application, the valve assembly 32 includes a first valve pipe 321, a second valve pipe 322, and a third valve pipe 323; wherein, along the length of the first valve pipe 321, one end of the first valve pipe 321 is connected to the main inlet pipe 31, and the other end has a first outlet connected to the first branch pipe 21; along the length of the second valve pipe 322, one end of the second valve pipe 322 is connected to the main inlet pipe 31, and the other end has a second outlet connected to the second branch pipe 22; along the length of the third valve pipe 323, one end of the third valve pipe 323 is connected to the main inlet pipe 31, and the other end has a second outlet connected to the second branch pipe 22; along the length of the third valve pipe 323, one end of the third valve pipe 323 is connected to the main inlet pipe 32 .... The main pipe 31 is connected to the third outlet, which is connected to the third branch pipe 23 at the other end. The first outlet, the second outlet, and the third outlet constitute the outlet end of the control component 3. The first valve pipe 321, the second valve pipe 322, and the third valve pipe 323 are all connected to the controller. When a fire alarm occurs in any, two, or three of the battery compartment 11, equipment compartment 12, and battery unit 5, the controller controls the corresponding first valve pipe 321, second valve pipe 322, and third valve pipe 323 to open, so as to deliver the fire-fighting medium to the corresponding fire area.

[0048] It is understood that valves (communicating with the controller) can be installed on the first valve pipe 321, the second valve pipe 322, and the third valve pipe 323. The controller controls the opening and closing of the valves to control the on / off of the first valve pipe 321, the second valve pipe 322, and the third valve pipe 323, thereby delivering the fire-fighting medium to the corresponding fire-affected area and achieving targeted and efficient fire suppression.

[0049] Reference Figure 9 As shown in one embodiment of this application, the first valve pipe 321 includes two first transition pipes 3211, one end of each of the two first transition pipes 3211 is connected to the main liquid inlet pipe 31, and the other end is connected to the first branch pipe 21. Each of the two first transition pipes 3211 is equipped with a first control valve 3212, and both first control valves 3212 are communicatively connected to the controller. That is, the two first transition pipes 3211 are connected in parallel, ensuring that even if one of the first control valves 3212 fails, the other first control valve 3212 can still operate normally, guaranteeing the delivery of the fire-fighting medium. Under normal operating conditions, both first control valves 3212 are closed, and the fire-fighting medium will not enter the first branch pipe 21. The controller monitors the status of each first control valve 3212 in real time to ensure that the system is in standby mode. When the detection component 4 (such as a smoke sensor, temperature sensor, etc.) detects a fire signal and transmits it to the controller, the controller will determine which first control valve 3212 needs to be opened according to preset logic. For example, the controller first attempts to open one of the first control valves 3212. If the first control valve 3212 is successfully opened, the fire extinguishing medium will enter the first branch pipe 21 through the corresponding first transition pipe 3211 to achieve fire extinguishing. If the first control valve fails to open (for example, due to malfunction or blockage), the controller will automatically switch to another first control valve 3212 to ensure that the fire extinguishing medium can smoothly enter the first branch pipe 21.

[0050] In this embodiment, by setting two parallel first transition pipes 3211 and first control valves 3212, redundancy is provided for the system. Even if one of the first control valves 3212 fails, the other first control valve 3212 can still work normally to ensure the delivery of fire-fighting medium. The redundancy design reduces the risk of fire extinguishing failure due to single-point failure and ensures that the system can operate normally in emergency situations. For example, a flow sensor can be installed in the first branch pipe 21 and the flow sensor is communicatively connected to the controller. After the controller controls the corresponding first control valve 3212 to open, it uses the flow sensor to detect the flow rate of the fire-fighting medium in the first branch pipe 21 in real time to determine whether the corresponding first control valve 3212 is open normally.

[0051] In this embodiment, as Figure 9 As shown, the second valve pipe 322 includes two second transition pipes 3221, one end of which is connected to the main inlet pipe 31 and the other end of which is connected to the second branch pipe 22. Each of the two second transition pipes 3221 is equipped with a second control valve 3222, and both second control valves 3222 are communicatively connected to the controller. This means the two second transition pipes 3221 are connected in parallel, ensuring that even if one second control valve 3222 fails, the other second control valve 3222 can still operate normally, guaranteeing the delivery of the fire-fighting medium. Under normal operating conditions, both second control valves 3222 are closed, preventing the fire-fighting medium from entering the second branch pipe 22. The controller monitors the status of each second control valve 3222 in real time, ensuring the system is in standby mode. When the detection component 4 (such as a smoke sensor, temperature sensor, etc.) detects a fire signal and transmits it to the controller, the controller will determine which second control valve 3222 needs to be opened based on preset logic. For example, the controller first attempts to open one of the second control valves 3222. If the second control valve 3222 is successfully opened, the fire extinguishing medium will enter the second branch pipe 22 through the corresponding second transition pipe 3221 to extinguish the fire. If the second control valve fails to open (for example, due to malfunction or blockage), the controller will automatically switch to the other second control valve 3222 to ensure that the fire extinguishing medium can smoothly enter the second branch pipe 22.

[0052] In this embodiment, by setting two parallel second transition pipes 3221 and second control valves 3222, redundancy is provided for the system. Even if one of the second control valves 3222 fails, the other second control valve 3222 can still work normally to ensure the delivery of fire-fighting medium. The redundancy design reduces the risk of fire extinguishing failure due to single-point failure and ensures that the system can operate normally in emergency situations. For example, a flow sensor can be installed in the second branch pipe 22 and the flow sensor is communicatively connected to the controller. After the controller controls the corresponding second control valve 3222 to open, it uses the flow sensor to detect the flow rate of the fire-fighting medium in the second branch pipe 22 in real time to determine whether the corresponding second control valve 3222 is open normally.

[0053] In this embodiment, as Figure 9 As shown, the third valve pipe 323 includes two third transition pipes 3231, one end of which is connected to the main inlet pipe 31 and the other end of which is connected to the third branch pipe 23. Each of the two third transition pipes 3231 is equipped with a third control valve 3232, and both third control valves 3232 are communicatively connected to the controller. This means the two third transition pipes 3231 are connected in parallel, ensuring that even if one third control valve 3232 fails, the other third control valve 3232 can still operate normally, guaranteeing the delivery of the fire-fighting medium. Under normal operating conditions, both third control valves 3232 are closed, preventing the fire-fighting medium from entering the third branch pipe 23. The controller monitors the status of each third control valve 3232 in real time, ensuring the system is in standby mode. When the detection component 4 (such as a smoke sensor, temperature sensor, etc.) detects a fire signal and transmits it to the controller, the controller will determine which third control valve 3232 needs to be opened based on preset logic. For example, the controller first attempts to open one of the third control valves 3232. If the third control valve 3232 is successfully opened, the fire extinguishing medium will enter the third branch pipe 23 through the corresponding third transition pipe 3231 to extinguish the fire. If the third control valve fails to open (e.g., due to malfunction or blockage), the controller will automatically switch to another third control valve 3232 to ensure that the fire extinguishing medium can smoothly enter the third branch pipe 23.

[0054] In this embodiment, redundancy is provided to the system by setting two parallel third transition pipes 3231 and third control valves 3232. Even if one of the third control valves 3232 fails, the other third control valve 3232 can still work normally to ensure the delivery of fire-fighting medium. The redundancy design reduces the risk of fire extinguishing failure due to single point of failure and ensures that the system can operate normally in emergency situations. For example, a flow sensor can be installed in the third branch pipe 23 and the flow sensor can be communicated with the controller. After the controller controls the corresponding third control valve 3232 to open, it can detect the flow rate of the fire-fighting medium in the third branch pipe 23 in real time through the flow sensor to determine whether the corresponding third control valve 3232 is open normally.

[0055] Understandably, the two first control valves 3212, the two second control valves 3222, and the two third control valves 3232 in this scheme can also be opened simultaneously. That is, when a fire signal is detected, the controller controls the two cooperating control valves to open simultaneously.

[0056] Reference Figure 9 As shown, in one embodiment of this application, the liquid inlet main pipe 31 is connected to a test pipe 311, and the test pipe 311 extends outward from the housing at least partially. A first solenoid valve 7 is provided on the test pipe 311. A pressure sensor 6 is also provided on the liquid inlet main pipe 31. Both the pressure sensor 6 and the first solenoid valve 7 are communicatively connected to the controller.

[0057] In this embodiment, each time the inlet pipe 31 is reconnected to the container or when it is necessary to check whether the connection is good, the controller first controls the first solenoid valve 7 on the test pipe 311 to open for a preset time (at which time the valve assembly 32 is in the closed state), so that some fire-fighting medium is discharged out of the energy storage container 1 along the test pipe 311. The opening time does not need to be very long. After the pressure sensor 6 shows that the pressure in the inlet pipe 31 has dropped, the controller can close the first solenoid valve 7 again. After the first solenoid valve 7 is closed, if the pressure sensor 6 on the inlet pipe 31 shows that the pressure value has risen, it indicates that there is no abnormality in the connection between the inlet pipe 31 and the fire-fighting medium delivery system. If the pressure sensor 6 shows that the pressure value remains unchanged, it indicates that there is an abnormality in the connection between the inlet pipe 31 and the fire-fighting medium delivery system, and no new fire-fighting medium flows into the inlet pipe 31.

[0058] In this embodiment, by quickly opening the first solenoid valve 7 and monitoring the pressure change in the liquid inlet pipe 31, it is possible to quickly confirm whether the connection between the liquid inlet pipe 31 and the box is normal, reducing inspection time. This enables a rapid inspection of the connection status between the box and the liquid inlet pipe 31. This design not only improves the reliability of the system, but also enhances the safety and fire extinguishing efficiency of the system.

[0059] Reference Figure 1 , Figure 4 As shown in one embodiment of this application, the detection component 4 includes a first smoke sensor (not shown), a second smoke sensor 41, and a third smoke sensor 42. The first smoke sensor is located within the battery pack 511 and is used to detect fire characteristics within the battery pack 511. That is, each battery pack 511 is equipped with at least one first smoke sensor, and the fire characteristics within the battery pack 511 are transmitted to the controller in real time, thereby enabling real-time monitoring of the operating status of the battery pack 511. The second smoke sensor 41 is located within the battery compartment 11 and is used to detect fire characteristics within the battery compartment 11. The second smoke sensor 41 transmits the fire characteristics within the battery compartment 11 to the controller in real time, thereby enabling real-time monitoring of the status within the battery compartment 11. The third smoke sensor 42 is located within the equipment compartment 12 and is used to detect fire characteristics within the equipment compartment 12. The third smoke sensor 42 transmits the fire characteristics within the equipment compartment 12 to the controller in real time, thereby enabling real-time monitoring of the status within the equipment compartment 12.

[0060] In this embodiment, multiple first smoke sensors, second smoke sensors 41 and third smoke sensors 42 can be provided to achieve comprehensive monitoring of all areas in the battery compartment 11, equipment compartment 12 and battery pack 511, and to ensure that signs of fire can be detected in a timely manner.

[0061] For example, the smoke sensor can be a photoelectric smoke sensor, an ionization smoke sensor, or a combination of photoelectric smoke sensors and ionization smoke sensors.

[0062] In this embodiment, the detection component 4 may also include a temperature sensor and a hazardous gas sensor. Through multi-dimensional detection of temperature, smoke and hazardous gases, potential fire risks can be monitored more comprehensively, reducing false alarms and missed alarms. For example, the temperature sensor can detect early abnormal temperature rises, and the hazardous gas sensor can detect leaks of hazardous gases, thereby achieving early warning.

[0063] Reference Figure 2 , Figure 10 , Figure 11 , Figure 12 As shown in one embodiment of this application, the energy storage container 1 further includes a drainage component 8, wherein the drainage component 8 includes a battery compartment drain pipe 81, an equipment compartment drain pipe 82, and a battery unit drain pipe 83, and each of the above pipes is provided with a drain valve for controlling the opening and closing of the above pipes.

[0064] Understandably, during fire suppression or normal system operation, all drain valves are closed, ensuring that the battery compartment drain pipe 81, equipment compartment drain pipe 82, and battery unit drain pipe 83 are not conductive, thus isolating the battery compartment 11, equipment compartment 12, and battery unit 5 from the external environment. After the fire is successfully extinguished, the controller initiates the drainage procedure. The controller first shuts down the control component 3 to disconnect from the fire-fighting medium delivery system, ensuring that no new fire-fighting medium enters the battery compartment 11, equipment compartment 12, or battery pack 511. Subsequently, the drainage operation begins, which involves opening the corresponding drain valves to make the battery compartment drain pipe 81 and / or equipment compartment drain pipe 82 and / or battery unit drain pipe 83 conductive, allowing the fire-fighting medium in the battery compartment 11, equipment compartment 12, and battery pack 511 to be discharged.

[0065] In this embodiment, as Figure 2 , Figure 6 , Figure 8 As shown, the battery compartment drain pipe 81 is located at the bottom of the battery compartment 11, and the battery compartment drain pipe 81 has a battery compartment drain outlet 811 extending upward into the battery compartment 11, for allowing fire-fighting media located in the battery compartment 11 to enter the battery compartment drain pipe 81 through the battery compartment drain outlet 811, and for discharging the fire-fighting media in the battery compartment 11 outward when the controller controls the battery compartment drain pipe 81 to open; as Figure 8 As shown, the battery compartment drain outlets 811 are arranged diagonally inside the battery compartment 11, which can ensure that the fire-fighting medium can flow smoothly into the battery compartment drain outlets 811 from all corners of the battery compartment 11, reducing drainage time and improving drainage efficiency.

[0066] In this embodiment, as Figure 10 , Figure 11 As shown, the equipment compartment drain pipe 82 is located at the bottom of the equipment compartment 12 and has an equipment compartment drain outlet 821 that communicates with the equipment compartment 12. This allows the fire-fighting medium located in the equipment compartment 12 to enter the equipment compartment drain pipe 82 through the equipment compartment drain outlet 821. When the controller controls the equipment compartment drain pipe 82 to open, it is used to discharge the fire-fighting medium in the equipment compartment 12 to the outside.

[0067] In this embodiment, as Figure 10 , Figure 12 As shown, the battery unit drain pipe 83 is located inside the battery compartment 11 and is sandwiched between the battery unit 5 and one side wall of the battery compartment 11 along the width direction. The battery unit drain pipe 83 is an S-shaped pipe, and each battery pack 511 in the battery unit 5 is connected to the battery unit drain pipe 83. It can be understood that the explosion-proof valve of each battery pack 511 is connected to the battery unit drain pipe 83. Figure 12As shown, a drain pipe 831 is connected to the bottom of the battery unit drain pipe 83. When the controller controls the battery unit drain pipe 83 to open, it is used to discharge the fire-fighting medium in the corresponding battery pack 511 outward through the battery unit drain pipe 83 and the drain pipe 831 to the energy storage container 1. It can be understood that since the explosion-proof valves of each battery pack 511 in the battery unit 5 are connected to the battery unit drain pipe 83, the battery unit drain pipe 83 can not only be used to discharge the fire-fighting medium, but also to discharge the harmful gases generated when the battery pack 511 experiences thermal runaway by connecting to the exhaust system, ensuring the safe operation of the system. This design not only improves the versatility of the system, but also enhances the safety and reliability of the system. For example, a hazardous gas sensor can be installed in the battery pack 511 to monitor the concentration of hazardous gases in real time, provide early warning, and ensure that effective measures can be taken in the early stage of thermal runaway, which helps to suppress the subsequent development trend of the fire.

[0068] In this embodiment, when a fire occurs inside the battery pack 511, that is, when the smoke sensor installed inside the battery pack 511 reaches the preset alarm threshold, fire extinguishing begins on the battery pack 511 where the fire has occurred. Fire extinguishing medium is delivered to the corresponding battery pack 511 through the fire extinguishing pipeline 2 to achieve immersion fire extinguishing. It should be noted that before delivering the fire extinguishing medium to the battery pack 511 where the fire has occurred, the controller needs to control the ventilation system to stop and disconnect the connection between the battery unit drain pipe 83 and the ventilation system to prevent the fire extinguishing medium from leaking out through the connection between the battery unit drain pipe 83 and the ventilation system.

[0069] In this embodiment, the drainage assembly 8 also includes a main drainage pipe 84. The battery compartment drainage pipe 81, the equipment compartment drainage pipe 82, and the outlet pipe 831 are all connected to the main drainage pipe 84. The drainage valves include second solenoid valves 85 respectively installed on the battery compartment drainage pipe 81, the equipment compartment drainage pipe 82, and the outlet pipe 831. The second solenoid valves 85 are communicatively connected to the controller. The other end of the main drainage pipe 84 extends outward from the energy storage container 1. When the system is operating normally or performing fire extinguishing, the controller controls all the above-mentioned second solenoid valves 85 to be in the closed state, thereby making the battery compartment drainage pipe 81, the equipment compartment drainage pipe 82, and the battery unit drainage pipe 83 in a non-conductive state. This isolates the battery compartment 11, the equipment compartment 12, and the battery unit 5 from the external environment during normal system operation, improving the system's sealing performance. Alternatively, when the system is performing fire extinguishing, the fire-fighting medium entering the battery compartment 11, the equipment compartment 12, or the battery pack 511 can completely fill the corresponding fire area and achieve the effect of immersion fire extinguishing.

[0070] It is understood that in this embodiment, the drain valves on the battery compartment drain pipe 81, battery unit drain pipe 83, and equipment compartment drain pipe 82 are all independently connected to the controller. When the detection component 4 detects fire characteristic information, the controller can execute different control modes on the corresponding drain valves according to the fire level, fire source location, and preset fire extinguishing strategy. For severe fires, immersion fire extinguishing is used to ensure no reignition, while for initial fires, non-immersion fire extinguishing is used, allowing the fire-fighting medium to flow through the fire area. This ensures both fire safety and protection of electrical equipment.

[0071] Specifically, when the fire characteristics detected by the first smoke sensor, the second smoke sensor 41, or the third smoke sensor 42 exceed the first alarm threshold, the controller determines it to be a high-risk fire. At this time, while the controller opens the control component 3 to deliver the fire-fighting medium, it keeps the drain valves of all pipelines closed, so that the fire-fighting medium completely fills and submerges the corresponding battery compartment 11, equipment compartment 12, or battery unit 5, thereby achieving the effect of submersion fire extinguishing.

[0072] When the fire characteristic information detected by the detection component 4 does not exceed the first alarm threshold but exceeds the second alarm threshold, the controller determines it to be an initial fire. At this time, the controller activates the control component 3 to deliver fire-fighting medium to the corresponding battery compartment 11, equipment compartment 12, or battery unit 5, and simultaneously opens the drain valve of the corresponding area, so that the fire-fighting medium continues to circulate, forming a spray cooling effect without complete submersion. For example, if there is a fire risk in the battery compartment 11, the controller opens the drain valve on the battery compartment drain pipe 81, and the fire-fighting medium enters the battery compartment 11 through the first branch pipe 21. At the same time, the battery compartment drain outlet 811 discharges in real time, keeping the battery unit 5 in a cooled but not submerged state, minimizing the impact of the fire-fighting medium on electrical components, thereby achieving a non-submersible fire-fighting effect.

[0073] It should be noted that the determination of the first alarm threshold and the second alarm threshold can be set according to the specific circumstances, and no limitation is made here.

[0074] In this embodiment, the test pipeline 311 and the main drain pipe 84 can be connected to each other, thereby enabling the discharge of part of the test fire-fighting medium from the test pipeline 311 and the main drain pipe 84 to the energy storage container 1 when testing the connection between the fire-fighting medium delivery system and the liquid inlet pipe 31.

[0075] In this embodiment, as Figure 10As shown, the drainage assembly 8 also includes a first liquid level sensor 86. The first liquid level sensor 86 is installed on the battery compartment drain pipe 81 on the side of the second solenoid valve 85 away from the main drain pipe 84, on the equipment compartment drain pipe 82 on the side of the second solenoid valve 85 away from the main drain pipe 84, and on the outlet pipe 831 on the side of the second solenoid valve 85 away from the main drain pipe 84. All of the first liquid level sensors 86 are communicatively connected to the controller. The reason for setting the first liquid level sensor 86 in this embodiment is to periodically discharge the condensate generated in the battery compartment drain pipe 81, the equipment compartment drain pipe 82, and the outlet pipe 831 during normal system operation, so as to ensure that the ambient humidity inside the energy storage container 1 is not affected.

[0076] It is understandable that during navigation, ships operate in a marine environment for extended periods, where the humidity is typically high and the air contains a large amount of water vapor. This water vapor inevitably causes condensation when it enters the battery compartment drain pipe 81, equipment compartment drain pipe 82, and battery unit drain pipe 83. To prevent this condensation from accumulating in these pipes and affecting the humidity inside the energy storage container 1, this embodiment provides a first liquid level sensor 86 on each of the battery compartment drain pipe 81, equipment compartment drain pipe 82, and battery unit drain pipe 83. This sensor detects the amount of water accumulated in the pipes. If the amount of water in the pipes is low, the first liquid level sensor 86 will not be triggered, and the corresponding second solenoid valve 85 will be closed. When the amount of water in the pipes reaches the preset alarm threshold of the first liquid level sensor 86, the controller controls the corresponding second solenoid valve 85 to open, thereby discharging the water from the pipes.

[0077] Furthermore, such as Figure 10 As shown, to avoid frequent alarms from the first liquid level sensor 86, there is a height difference in the pipelines between each second solenoid valve 85 and the first liquid level sensor 86. This arrangement ensures that when there is a small amount of water in the battery compartment drain pipe 81, equipment compartment drain pipe 82, and outlet pipe 831, this small amount of water will accumulate in the pipelines at a relatively lower height. When a small amount of water is stored in the battery compartment drain pipe 81, equipment compartment drain pipe 82, and outlet pipe 831, its impact on the ambient humidity inside the energy storage container 1 is weak (negligible). Therefore, when a small amount of water is stored in the above pipelines, the first liquid level sensor 86 will not generate an alarm, thus reducing the alarm frequency of the first liquid level sensor 86.

[0078] It should be noted that when executing fire extinguishing commands, the controller will prioritize ensuring that the fire extinguishing medium can be successfully filled into the battery compartment 11, equipment compartment 12, and battery unit 5. During this process, even if the first liquid level sensor 86 is triggered and an alarm is triggered, the controller will not control the second solenoid valve 85 to open, so as to prevent the fire extinguishing medium from being discharged during the fire extinguishing process. Only when the energy storage container 1 is operating normally and the first liquid level sensor 86 is triggered and an alarm is triggered will the controller control the corresponding second solenoid valve 85 to open, so as to discharge the condensate generated in the energy storage container 1.

[0079] In this embodiment, the first liquid level sensor 86 can be a resistive (conductivity) leakage sensor, a capacitive leakage sensor, or other types of sensors. The resistive (conductivity) leakage sensor detects changes in conductivity between electrodes when liquid comes into contact with them. When liquid comes into contact with the two electrodes, the conductivity of the liquid decreases the resistance between the electrodes, triggering an alarm. The capacitive leakage sensor utilizes the difference between the dielectric constant of the liquid and that of air. When liquid comes into contact with the sensor surface, the capacitance value changes, triggering the detection circuit.

[0080] In this embodiment, the main drain pipe 84, the first liquid level sensor 86, and the second solenoid valve 85 are all located at the bottom of the equipment compartment 12. To prevent condensate from dripping onto these components, a protective shell is provided above them. During inspection or maintenance, the protective shell can be opened for inspection or maintenance.

[0081] In one embodiment of this application, a second liquid level sensor (not shown in the figure) is provided on the top of the battery compartment 11 and is communicatively connected to the controller. When a fire occurs in the battery compartment 11 and fire-fighting medium is filled into the battery compartment 11 through the fire-fighting pipeline 2, the setting height of the second liquid level sensor in the battery compartment 11 is used to determine the amount of fire-fighting medium to be filled into the battery compartment 11, so as to prevent excessive fire-fighting medium in the battery compartment 11 from leaking into the equipment compartment 12, and also reduce potential damage caused by fire-fighting medium leakage.

[0082] In this embodiment, when the fire-fighting medium reaches the height of the second liquid level sensor, the controller controls the control component 3 to cut off the connection with the fire-fighting pipeline 2 in the battery compartment 11, thereby stopping the continued delivery of fire-fighting medium into the battery compartment 11.

[0083] In this embodiment, the second liquid level sensor, smoke sensor, temperature sensor, and hazardous gas sensor located at the top of the battery compartment 11 need to be explosion-proof certified because the above-mentioned area is a hazardous gas accumulation area. When the battery pack 511 experiences thermal runaway, the gas produced is mainly hydrogen, which has a lower density than air, and thus will accumulate in the above-mentioned area to ensure safe use.

[0084] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention.
