Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, and in particular to a battery energy storage container. Background Technology

[0002] Existing energy storage containers consist of a container body, multiple partitions, cluster-level fire extinguishing cylinders, and compartment-level fire extinguishing cylinders. The container body has a cavity. Each partition is located within the cavity, dividing it into an electrical room and multiple compartments. Each compartment contains several cluster racks for housing battery packs. Cluster-level and compartment-level fire extinguishing cylinders are located in the electrical room. The compartment-level fire extinguishing cylinders are connected to compartment-level fire extinguishing pipelines, which extend sequentially through each compartment. Each compartment-level fire extinguishing pipeline is equipped with a corresponding nozzle. Similarly, cluster-level fire extinguishing cylinders are connected to cluster-level fire extinguishing pipelines, which extend sequentially through each cluster rack. Each cluster-level fire extinguishing pipeline is equipped with a corresponding nozzle. When a fire occurs inside the compartment, each nozzle extinguishes the fire by spraying fire extinguishing gas into the corresponding compartment. Although this method can ensure the overall safety of the battery compartment to a certain extent and prevent the fire from spreading on a large scale, the nozzles on the existing cluster-level fire extinguishing pipeline can only extend to the outside between the two rows of clusters in the compartment, and do not extend to the inside of the corresponding clusters. This results in insufficient precision in fire extinguishing, limited fire extinguishing effect, and inability to achieve precise fire extinguishing.

[0041] See Figures 1 to 4As shown in the figure, this application provides a battery energy storage container, including: a container body (not shown), multiple partitions (not shown), a compartment-level fire protection pipe 1, and a cluster-level fire protection pipe 2. The container body has a cavity. Each of the partitions is disposed within the cavity, and each partition divides the cavity into multiple compartments, each compartment being provided with a plurality of cluster racks 3. The compartment-level fire protection pipe 1 extends sequentially through each compartment, and each compartment-level fire protection pipe 1 is provided with a corresponding nozzle a. The cluster-level fire protection pipe 2 includes a main pipe 21 and multiple branch pipes 22. The main pipe 21 extends along the length direction of the container body, and each of the branch pipes 22 is sequentially spaced along the length direction of the compartment-level fire protection pipe 1, and each of the branch pipes 22 is connected to the main pipe 21. Each of the branch pipes 22 extends into the interior of the corresponding cluster rack 3, and a nozzle a is provided on the pipe section of each branch pipe 22 located inside the cluster rack 3. Each branch pipe 22 of the battery energy storage container of this application can extend into the interior of the corresponding cluster 3. When a fire occurs in the battery pack 4 on a certain cluster 3, the energy storage container can open the corresponding nozzle a to carry out precise fire extinguishing operations inside the corresponding cluster 3, which improves the accuracy of fire extinguishing and the fire-fighting effect is better.

[0042] The cluster frame 3 comprises multiple frames, each arranged sequentially along the length of the container body. Adjacent frames on the cluster frame 3 are connected, with gaps between them. Multiple battery packs 4 are mounted on each frame along its height. Branch pipes 22 extend into the gaps of the corresponding cluster frames 3, and nozzles a are installed on the pipe sections of the branch pipes 22 within the gaps. When a fire occurs in a battery pack 4 on a certain frame, the battery storage container of this application can activate the corresponding nozzles a to spray fire-fighting gas inside the corresponding cluster frame 3, thereby extinguishing the fire as quickly as possible and controlling it to a minimum.

[0043] The main pipe 21 is located on one side of the container body along the width direction. Each branch pipe 22 has a first extension section 221 and a distribution section 222. The first extension section 221 extends at least along the width direction of the container body. One end of the distribution section 222 is connected to the first extension section 221, and the other end of the distribution section 222 extends into the gaps of the corresponding cluster frame 3.

[0044] Each of the aforementioned cluster racks 3 is divided into two rows of cluster racks 3, respectively located on both sides of the container body along the width direction. The first extension section 221 extends to the area between the two rows of cluster racks 3. The first extension section 221 includes a first pipe section 2211, a second pipe section 2212, and a third pipe section 2213. The first pipe section 2211 extends along the width direction of the container body, with one end connected to the main pipe 21 and the other end extending between the two rows of cluster racks 3. The second pipe section 2212 extends along the length direction of the container body, with one end connected to the first pipe section 2211 and the other end extending to the top of the corresponding cluster rack 3. The third pipe section 2213 extends along the height direction of the container body, with one end connected to the second pipe section 2212 and the other end extending downward into the space between two opposing cluster racks 3 along the width direction of the container body. The distribution section 222 has two second extension sections 2221, one end of which is connected to the first extension section 221. Each of the two second extension sections 2221 extends into two opposing cluster racks 3 along the width direction of the container body. One end of each of the two second extension sections 2221 is connected to the third pipe section 2213, and the other end extends into the two opposing cluster racks 3 along the width direction of the container body.

[0045] The second extension section 2221 includes a main extension section 2221a, a side extension section 2221b, and several lower extension sections 2221c. The main extension section 2221a extends along the width direction of the container body, and one end of the main extension section 2221a is connected to the first extension section 221. The side extension sections 2221b extend along the arrangement direction of each frame of the cluster frame 3, and are connected to the main extension section 2221a. The top ends of each of the lower extension sections 2221c are connected to the side extension section 2221b, and each of the lower extension sections 2221c is located within a gap in the cluster frame 3. The lower extension sections 2221c are provided with the nozzles a. The main extension section 2221a and the side extension sections 2221b are vertically connected. The main extension 2221a extends into the interior of the central frame of the cluster frame 3, the side extension 2221b penetrates the interior of the central frame, and the lower extension 2221c is located in the gap between adjacent frames.

[0046] In one possible implementation, the cluster frame 3 comprises three frames. The main extension section 2221a extends to the inner side of the middle frame. The side extension sections 2221b penetrate both ends of the middle frame and extend into the gaps on both sides of the middle frame. Two lower extension sections 2221c are located in the two gaps of the cluster frame 3, with their top ends connected to the side extension sections 2221b, and extending towards the bottom of the container body. The nozzles a connected to the lower extension sections 2221c are disposed in the gaps between adjacent frames. When a fire occurs on a battery pack 4 on a certain frame of the cluster frame 3, the energy storage container can open the corresponding nozzles a to spray fire-fighting gas between the corresponding frames, resulting in higher accuracy and better fire-fighting effect.

[0047] In one possible implementation, a valve 5 is provided on the main extension section 2221a. The valve 5 is used to open or close the fire-fighting gas passage at a corresponding position on the main extension section 2221a, so as to facilitate precise control of the fire-fighting gas release.

[0048] In one possible implementation, the battery pack 4 is an air-cooled battery pack 4, which has an air inlet 41 facing the gap. When a fire occurs in the battery pack 4 on a certain frame of the cluster 3, the energy storage container can open the corresponding nozzle a to spray fire-fighting gas between the corresponding frames. The fire-fighting gas can easily enter the interior of the battery pack 4 through the air inlet 41 with the airflow to extinguish the fire, resulting in higher fire-fighting accuracy.

[0049] In one possible implementation, the battery storage container includes cluster-level fire extinguishing gas cylinders 6 and compartment-level fire extinguishing gas cylinders 7, both housed within the container body. The compartment-level fire extinguishing gas cylinders 7 are connected to the compartment-level fire extinguishing pipeline 1, and the cluster-level fire extinguishing gas cylinders 6 are connected to the cluster-level fire extinguishing pipeline 2. Each of the cluster-level and compartment-level fire extinguishing gas cylinders (6 and 7) provides protection for both, effectively ensuring sufficient extinguishing gas usage for single compartment-level spraying and multiple cluster-level spraying. The gas spraying from the compartment-level fire extinguishing pipeline 1 and the cluster-level fire extinguishing pipeline 2 is independent of each other, jointly protecting the fire safety of each compartment.

[0050] In one possible implementation, the battery storage container includes multiple composite detectors (not shown) disposed inside the container body. Each composite detector is located on top of a corresponding cluster 3. The composite detector 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.

[0051] The battery storage container may also include a fire control panel (not shown). The composite detector, valve 5, and nozzles a on the cluster-level fire extinguishing pipeline 2 and the compartment-level fire extinguishing pipeline 1 are all electrically connected to the fire control panel. In the event of a fire, according to the principle of "power off first, fire extinguishing later," the circuits connected within the cluster-level energy storage container can be disconnected first, and then fire extinguishing operations can be carried out. When a composite detector detects a fire signal, it will send it to the fire control panel, which will control the valve 5 and nozzle a at the corresponding location to open and carry out fire extinguishing operations.

[0052] 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.
