Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, and in particular to an energy storage container that combines compartments. Background Technology

[0002] Existing energy storage containers typically include a battery compartment and an electrical chamber, with multiple racks inside the battery compartment for housing battery packs. However, these racks are not separated from each other, posing a safety hazard. If a fire breaks out in a battery pack on one rack, the fire and heat can rapidly spread throughout the entire battery compartment, potentially causing extensive damage to the equipment inside and even triggering a more serious safety accident, posing a significant threat to personnel safety and property.

[0003] Current technology typically involves installing fire suppression piping within the battery compartment, with multiple nozzles on these pipes. When a fire occurs within the battery compartment, each nozzle sprays extinguishing gas throughout the compartment to extinguish the fire. While this method can ensure the overall safety of the battery compartment and prevent large-scale fire spread to some extent, it lacks precision and cannot achieve accurate fire suppression. Because the fire suppression operation involves the entire compartment, even healthy battery packs can be affected by the extinguishing gas, potentially leading to performance degradation or other malfunctions, thus impacting the normal operation and lifespan of the battery compartment.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0045] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0046] See Figures 1 to 4As shown, this application provides an energy storage container with a combined compartment and cluster level, including: a container body 1, multiple partition walls 2, cluster-level fire-fighting gas cylinders 3, and compartment-level fire-fighting gas cylinders 4. The container body 1 has a cavity. Each of the partition walls 2 is disposed within the cavity, dividing the cavity into an electrical room and multiple compartments, each compartment having several cluster racks 5. Each cluster rack 5 has multi-layer battery cavities extending along its height, each battery cavity for placing battery packs. The cluster-level fire-fighting gas cylinders 3 and compartment-level fire-fighting gas cylinders 4 are disposed in the electrical room. The compartment-level fire-fighting gas cylinders 4 are connected to compartment-level fire-fighting pipelines 6, which extend sequentially through each compartment. Each compartment-level fire-fighting pipeline 6 has a corresponding nozzle for each compartment. The cluster-level fire-fighting gas cylinders 3 are connected to cluster-level fire-fighting pipelines 7, which extend sequentially through each cluster rack 5. Each cluster-level fire-fighting pipeline 7 has a corresponding nozzle for each cluster rack 5. The cluster-level fire extinguishing gas cylinder 3 and the compartment-level fire extinguishing gas cylinder 4 each have one cylinder for protection, effectively ensuring the amount of extinguishing gas used for a single compartment-level spray and multiple cluster-level sprays. The gas spraying of the compartment-level fire extinguishing pipeline 6 and the cluster-level fire extinguishing pipeline 7 is independent of each other, jointly protecting the fire safety of the battery compartment. The energy storage container combining compartment and cluster levels in this application adds a partition wall 2 inside the container body 1, which divides the cavity into an electrical room and multiple compartments. The compartment-level fire extinguishing pipeline 6 extends sequentially through each compartment, and the cluster-level fire extinguishing pipeline 7 extends sequentially through each of the cluster racks 5. When a battery pack on a certain cluster rack 5 catches fire, the energy storage container can open the corresponding nozzles for precise fire extinguishing, improving the accuracy of fire extinguishing, reducing the scope of fire impact, and preventing the spraying of fire extinguishing gas into compartments where no fire has occurred, thus avoiding affecting battery packs in other compartments.

[0047] The cluster-level energy storage container includes two rows of cluster racks 5, which extend along the two length sides of the container body 1, respectively. A central cavity is formed between the two rows of cluster racks 5. The central cavity includes the space between the two rows of cluster racks 5 and the space between the two rows of cluster racks 5 and the top of the container body 1. A compartment-level fire-fighting pipeline 6 extends along the central cavity, sequentially passing through each of the partition walls 2 and each of the compartments. The compartment-level fire-fighting pipeline 6 can extend along the top of the central cavity, meaning it is suspended from the top of the container body 1. By placing the compartment-level fire-fighting pipeline 6 at the top of the central cavity, when a fire occurs in a cluster rack 5, the corresponding nozzles on the compartment-level fire-fighting pipeline 6 will spray fire-fighting gas to extinguish the fire as quickly as possible and control it to a minimum.

[0048] In one possible implementation, the cluster-level energy storage container includes multiple compartment-level detectors 8. Each compartment-level detector 8 is located within a corresponding compartment, near the top side of the compartment. Each compartment-level detector 8 can be a five-in-one detector, including a hydrogen sensor, a carbon monoxide sensor, a VOC sensor, a smoke detector, and a temperature sensor. The hydrogen sensor monitors hydrogen concentration, the carbon monoxide sensor detects carbon monoxide concentration, the VOC sensor monitors volatile organic compounds, the smoke detector monitors smoke using photoelectric or ionization principles, and the temperature sensor monitors ambient temperature in real time. At least one compartment-level detector 8 is installed in each compartment.

[0049] The cluster-level fire suppression piping 7 includes a main pipe 71 and multiple branch pipes 72. The main pipe 71 extends along the length of the housing 1. Each branch pipe 72 is connected to the main pipe 71 at one end and extends to the corresponding cluster rack 5 at the other end, with a nozzle provided at the end of each branch pipe 72. The main pipe 71 passes through each partition wall 2 sequentially and through each compartment sequentially. Each branch pipe 72 is located in each compartment, with one end connected to the portion of the main pipe 71 located in the corresponding compartment and the other end extending to the cluster rack 5 in the corresponding compartment.

[0050] The periphery of the housing 1 includes two end walls 11 and two main walls 12. The two main walls 12 are spaced apart and parallel to each other. The two end walls 11 are located at both ends of the main walls 12 and connect to the two main walls 12 respectively. The end walls 11 are located at both ends of the housing 1 along its length. The cavity forms a side cavity between each row of clusters 5 and the main wall 12. That is, the side cavity is the chamber on the side of the cavity closest to the main wall 12. The main pipeline 71 is located in the side cavity and extends along the side cavity. One end of each branch pipeline 72 is connected to the main pipeline 71, and the other end extends to one side of the central cavity. It should be noted that the side cavity includes the space between the main wall 12 and the adjacent row of clusters 5 and the space between the main wall 12 and the adjacent row of clusters 5 and the top of the housing 1. The main pipeline 71 can extend along the top of the side cavity without affecting the installation of other structures inside the housing 1.

[0051] In one possible implementation, the branch pipe 72 includes a first pipe segment 721, a second pipe segment 722, and a third pipe segment 723. The first pipe segment 721 extends along the width direction of the housing 1, with one end connected to the main pipe 71 and the other end extending to the central cavity. The second pipe segment 722 extends along the length direction of the housing 1, with one end connected to the first pipe segment 721 and the other end extending to the top of the corresponding cluster rack 5. The third pipe segment 723 extends along the height direction of the housing 1, with one end connected to the second pipe segment 722 and the other end extending downwards into the space between two opposing cluster racks 5 along the width direction of the housing 1. The housing 1 has a top wall 13. The first pipe section 721 and the second pipe section 722 can be connected to the top wall 13 and extend along the top wall 13. The third pipe section 723 is connected to the second pipe section 722 and extends downward in the middle of the cavity in a direction perpendicular to the top wall 13. The third pipe section 723 extends between two cluster racks 5 and can be responsible for the fire fighting operations of two opposite cluster racks 5 at the same time.

[0052] Each of the first pipe segments 721 is close to the partition wall 2 and extends along the corresponding partition wall 2. Multiple connectors may be provided on the partition wall 2, with each connector arranged sequentially along the direction of extension of the first pipe segment 721. The connectors are used to fix each of the first pipe segments 721 to the partition wall 2. The connectors may be bolts, cable ties, etc., and this application does not limit the specific structure of the connectors.

[0053] The main wall 12 of the enclosure 1 has multiple doors 121, each equipped with an air conditioner 10, with each air conditioner 10 facing one of the racks 5. Both main walls 12 have multiple doors 121, which can open the compartment, allowing battery packs on the two rows of racks 5 to be placed back-to-back. This facilitates opening the doors 121, arranging the racks 5, and installing / removing the battery packs. The air conditioners 10 on each door 121 are responsible for cooling the adjacent racks 5; their proximity to the adjacent racks 5 ensures effective cooling.

[0054] In one possible implementation, the cluster-level combined energy storage container includes multiple cluster-level sensors 9. Each cluster-level sensor 9 is disposed within a cavity, and each cluster-level sensor 9 is located on the top of the corresponding cluster frame 5 near the main wall 12. The cluster-level sensor 9 can also be a five-in-one detector used to monitor the battery packs on the corresponding cluster frame 5.

[0055] In one possible implementation, the cluster-level combined energy storage container includes a fire hose (not shown) extending along the length of the container body 1. The fire hose passes sequentially through each of the compartments, and each compartment has a spray nozzle. In the event of a large fire, if neither the cluster-level fire extinguishing gas nor the compartment-level fire extinguishing gas can suppress the spread of the fire, the fire hose can be activated to spray water into the corresponding burning compartment to extinguish the fire, confining the fire to that compartment. Due to the partition wall 2, the fire will not easily spread to other compartments.

[0056] The cluster-level combined energy storage container may also include a fire control unit (not shown). The compartment-level detectors 8, the cluster-level sensors 9, and the nozzles on the cluster-level fire-fighting pipes 7 and compartment-level fire-fighting pipes 6 are all electrically connected to the fire control unit. In the event of a fire, according to the principle of "power off first, fire extinguishing later," the circuits connected within the cluster-level combined energy storage container can be disconnected first, and then fire extinguishing operations can be carried out. Based on the alarm level of the compartment-level detectors 8, fire protection can be divided into three levels: pre-fire alarm, first-level fire alarm, and second-level fire alarm. When any one of the cabin-level detectors 8 reaches a low concentration alarm for combustible gas, on the one hand, the detection range of combustible gases VOC and H2 is relatively wide, making it easy to reach the low threshold alarm; on the other hand, the batteries on the cluster rack 5 also release some H2, CO, and alkane gases during charging and discharging, which, upon accumulation, will also trigger a low threshold alarm for combustible gases. Therefore, this alarm situation is classified as a pre-fire alarm. In the pre-fire alarm state, the cabin-level detector 8 at the corresponding location uploads alarm information to the fire control panel, and the fire control panel turns on the air conditioner 10 at the corresponding location to reduce the concentration of combustible gases. If the concentration of combustible gases continues to rise, the smoke, temperature, CO, and H2 levels will be monitored. 2. When any two values ​​of VOC exceed the set alarm threshold, it can be determined that the system is in an abnormal working state and a fire may be occurring. This is a Level 1 fire alarm, and the fire control panel will prevent the battery pack on the cluster rack 5 from charging or discharging. If the fire continues to worsen, and the temperature reaches the alarm level, when any two of the smoke, CO, H2, and VOC exceed the set alarm threshold, it is a serious Level 2 fire alarm. This requires not only power outage but also firefighting operations. Specifically, the nozzles on the cluster-level fire extinguishing pipeline 7 and the compartment-level fire extinguishing pipeline 6 at the specific location of the fire should be opened to spray fire extinguishing gas to prevent the fire from spreading further. When a large fire occurs and neither the cluster-level nor the compartment-level fire extinguishing gas can suppress the spread of the fire, the fire hoses can be activated to spray water into the corresponding burning compartment to extinguish the fire and control it within that compartment. Due to the partition wall 2, the fire will not easily spread to other compartments.

[0057] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
