Description

Technical Field

[0001] This utility model belongs to the field of battery safety technology, specifically relating to a distributed fire-fighting device and energy storage system. Background Technology

[0002] With the development of new energy technologies, battery energy storage systems are playing an increasingly important role in the energy sector. However, batteries may cause fires during operation due to overheating, short circuits, or other reasons, posing a serious threat to personnel safety and equipment. To prevent and address the potential fire risks that may occur during the operation of battery energy storage equipment and to ensure the safe operation of the equipment, it is usually necessary to configure battery energy storage fire suppression devices in the battery energy storage system.

[0003] Existing battery energy storage fire protection devices typically employ centralized fire protection systems, which often suffer from technical problems such as excessive space occupied by fire protection modules, high overall maintenance costs, and slow response speed when dealing with fires in battery energy storage systems. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a distributed fire-fighting device and energy storage system to solve the technical problems of existing battery energy storage fire-fighting devices, such as excessive space occupied by the fire-fighting module, high overall maintenance cost, and slow response speed when dealing with fires in battery energy storage systems.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A distributed fire-fighting device includes a fire controller and multiple distributed fire-fighting units installed in a battery compartment and corresponding one-to-one with each battery cluster in the battery compartment.

[0007] The distributed fire protection unit includes a distributed fire protection module, fire protection piping, multiple valves, and multiple sensor components. The distributed fire protection module is connected to the internal structure of each battery pack of the corresponding battery cluster through the fire protection piping. Each valve is installed on the fire protection piping, and each battery pack is equipped with a corresponding valve. The valve is used to control the connection and disconnection between the distributed fire protection module and the internal structure of the corresponding battery pack. Each battery pack is equipped with a corresponding sensor component.

[0008] The sensor assembly is used to monitor the abnormality within the corresponding battery pack. The fire controller is used to control the valve corresponding to the abnormal battery pack to open according to the abnormal signal sent by the sensor assembly, and to control the distributed fire protection module to inject fire extinguishing agent into the abnormal battery pack.

[0009] Compared to existing battery-powered fire suppression systems, which often require large fire-fighting modules outside the battery compartment and thus necessitate dedicated space for these modules, the distributed fire suppression system provided by this invention utilizes the remaining space within the battery compartment by arranging all distributed fire-fighting modules within the compartment and corresponding each distributed fire-fighting unit to a battery cluster within the compartment. This effectively solves the problem of excessive space occupation in existing battery-powered fire suppression systems. Furthermore, in the event of a malfunction, only the faulty distributed fire-fighting unit needs to be repaired and replaced individually, eliminating the need for overall repair and replacement, thus effectively reducing maintenance costs.

[0010] Meanwhile, compared to existing battery energy storage fire-fighting devices that typically require fire-fighting modules to be placed outside the battery compartment, the distributed fire-fighting device provided by this invention arranges each of the distributed fire-fighting modules inside the battery compartment. By utilizing the fire-fighting pipelines and valves, the fire-extinguishing agent can reach the battery pack via the shortest route, enabling the distributed fire-fighting device provided by this invention to have a faster response speed when dealing with fires in battery energy storage systems.

[0011] Furthermore, the fire protection piping includes a main fire protection pipe and multiple fire protection branch pipe assemblies;

[0012] One end of the fire main pipe is connected to the outlet of the distributed fire protection module. The fire main pipe is located on the outside of the corresponding battery cluster. Each valve is installed on the fire main pipe, and each valve is equipped with a corresponding fire branch pipe assembly.

[0013] The outlet of each valve is connected to the internal structure of the corresponding battery pack via the corresponding fire branch pipe assembly.

[0014] By placing the fire main pipe on the outside of the corresponding battery cluster and connecting the outlet of each valve to the inside of the corresponding battery pack through the corresponding fire branch pipe assembly, all valves can be placed on the outside of the corresponding battery pack. Compared with the valve placement method usually used in existing battery energy storage fire protection devices, this method can save the space occupied by placing valves inside the battery pack by making reasonable use of the remaining space in the battery compartment, thereby reducing the volume of the battery pack.

[0015] Furthermore, the fire branch pipe assembly includes a first outlet pipe and a first nozzle; the outlet of each valve is connected to the interior of the corresponding battery pack through the corresponding first outlet pipe;

[0016] The first nozzle is installed on one end of the first water outlet pipe that extends into the inside of the battery pack.

[0017] In another technical solution, the fire branch pipe assembly includes a second outlet pipe and a second nozzle;

[0018] The second nozzle is fixedly installed on the outer shell of the battery pack. The water outlet of the second nozzle extends into the outer shell of the battery pack, and the water inlet of the second nozzle extends out of the outer shell of the battery pack. The second water outlet pipe is connected between the water inlet of the second nozzle and the liquid outlet of the valve.

[0019] By fixing the second nozzle to the outer shell of the battery pack, with the water outlet of the second nozzle extending into the outer shell of the battery pack and the water inlet of the second nozzle extending out of the outer shell of the battery pack, compared to the installation method of installing the nozzle entirely inside the battery pack, the space occupied by the nozzle being placed entirely inside the battery pack can be saved, thus reducing the size of the battery pack.

[0020] Furthermore, the distributed fire suppression system also includes connecting pipelines;

[0021] The outlet of each of the distributed fire protection modules is connected to the connecting pipeline, and one end of each of the fire protection pipelines is connected to the connecting pipeline.

[0022] By setting up the connecting pipeline, each of the distributed fire protection modules of the distributed fire protection device provided by this utility model can inject fire extinguishing agent into any abnormal battery pack. When the distributed fire protection module corresponding to the abnormal battery pack malfunctions, the fire controller can control other distributed fire protection modules to inject fire extinguishing agent into the abnormal battery pack, which can greatly improve the reliability of fire prevention and response.

[0023] Furthermore, all of the valves described are electrically controlled valves.

[0024] Furthermore, the sensor assembly includes a smoke sensor.

[0025] Furthermore, the sensor assembly includes a temperature sensor.

[0026] Furthermore, the distributed fire suppression module is installed on one side of the corresponding battery cluster.

[0027] By installing the distributed fire suppression module on one side of the corresponding battery cluster, the distance that the fire extinguishing agent needs to reach the battery pack can be further reduced, enabling the distributed fire suppression device provided by this invention to have a faster response speed when dealing with fires in battery energy storage systems.

[0028] Based on the distributed fire-fighting device provided by this utility model, this utility model also provides an energy storage system, including: multiple battery clusters installed in the battery compartment, and the distributed fire-fighting device provided by this utility model;

[0029] The battery cluster includes multiple battery packs, and each battery cluster is configured in a one-to-one correspondence with each distributed fire protection unit of the distributed fire protection device. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Example 1:

[0036] like Figure 1 As shown, this embodiment 1 provides a distributed fire protection device, including a fire controller 6 and multiple distributed fire protection units installed in the battery compartment and corresponding one-to-one with each battery cluster 8 in the battery compartment;

[0037] The distributed fire protection unit includes a distributed fire protection module 1, a fire protection pipeline 4, multiple valves 5, and multiple sensor components 2. The distributed fire protection module 1 is connected to the internal parts of each battery pack 8.1 of the corresponding battery cluster 8 through the fire protection pipeline 4. Each valve 5 is installed on the fire protection pipeline 4, and each battery pack 8.1 is equipped with a corresponding valve 5. The valve 5 is used to control the connection and disconnection between the distributed fire protection module 1 and the internal parts of the corresponding battery pack 8.1. Each battery pack 8.1 is equipped with a corresponding sensor component 2.

[0038] Sensor component 2 is used to monitor abnormalities within the corresponding battery pack 8.1. Fire controller 6 is used to control the valve 5 corresponding to the abnormal battery pack 8.1 to open based on the abnormal signal sent by sensor component 2, and to control the distributed fire protection module 1 to inject fire extinguishing agent into the abnormal battery pack 8.1.

[0039] Compared to existing battery-powered fire suppression systems, which often require large fire suppression modules outside the battery compartment and thus necessitate dedicated space for these modules, the distributed fire suppression system provided by this invention utilizes the remaining space within the battery compartment by arranging each distributed fire suppression module 1 within the compartment and corresponding each distributed fire suppression unit to a battery cluster 8 within the compartment. This effectively solves the problem of excessive space occupation in existing battery-powered fire suppression systems. Furthermore, in the event of a malfunction, only the faulty distributed fire suppression unit needs to be repaired or replaced individually, eliminating the need for overall repair and replacement, thus effectively reducing maintenance costs.

[0040] Meanwhile, compared to existing battery energy storage fire-fighting devices that typically require fire-fighting modules to be placed outside the battery compartment, the distributed fire-fighting device provided by this utility model arranges each distributed fire-fighting module 1 inside the battery compartment. By utilizing fire-fighting pipelines 4 and valves 5, the fire extinguishing agent can reach the battery pack 8.1 via the shortest route, enabling the distributed fire-fighting device provided by this utility model to have a faster response speed when dealing with fires in battery energy storage systems.

[0041] In this embodiment 1, specifically, as follows: Figure 1 As shown, each sensor component 2, each valve 5, and each distributed fire protection module 1 are electrically connected to the fire controller 6 via control line 7.

Each valve 5 is installed on the fire main pipe, and each valve 5 is equipped with a corresponding fire branch pipe assembly.

[0044] The outlet of each valve 5 is connected to the internal structure of the corresponding battery pack 8.1 through the corresponding fire branch pipe assembly.

[0045] By placing the fire main pipe on the outside of the corresponding battery cluster 8 and connecting the outlet of each valve 5 to the inside of the corresponding battery pack 8.1 through the corresponding fire branch pipe assembly, each valve 5 can be placed on the outside of the corresponding battery pack 8.1. Compared with the existing battery energy storage fire protection device, which usually uses valves 5 inside the pack, this method can save the space occupied by placing valves 5 inside the battery pack 8.1 by making reasonable use of the remaining space in the battery compartment, thus reducing the volume of the battery pack 8.1.

[0046] The fire branch pipe assembly includes various configuration options, including but not limited to:

[0047] Option 1:

[0049] The first nozzle is installed on one end of the first water outlet pipe that extends into the inside of the battery pack 8.1.

[0050] Option 2:

[0051] The fire branch pipe assembly includes a second outlet pipe and a second nozzle 3;

[0052] The second nozzle 3 is fixedly installed on the outer shell of the battery pack 8.1. The water outlet of the second nozzle 3 extends into the outer shell of the battery pack 8.1, and the water inlet of the second nozzle 3 extends out of the outer shell of the battery pack 8.1. The second water outlet pipe is connected between the water inlet of the second nozzle 3 and the liquid outlet of the valve 5.

[0053] In this embodiment 1, as Figure 1 As shown, the configuration of the fire branch pipe assembly adopts the above-mentioned Scheme 2.

[0054] By fixing the second nozzle 3 to the outer shell of the battery pack 8.1, the water outlet of the second nozzle 3 extends into the outer shell of the battery pack 8.1, and the water inlet of the second nozzle 3 extends out of the outer shell of the battery pack 8.1. Compared with the installation method of installing the nozzle entirely inside the battery pack 8.1, this method can save the space occupied by the nozzle being placed entirely inside the battery pack 8.1 and reduce the volume of the battery pack 8.1.

[0055] Preferably, in this embodiment 1, as Figure 1 As shown, the distributed fire protection system also includes a connecting pipe 9;

[0056] The outlet of each distributed fire protection module 1 is connected to the connecting pipe 9, and one end of each fire protection pipe 4 is connected to the connecting pipe 9.

[0057] By setting up the connecting pipeline 9, each distributed fire protection module 1 of the distributed fire protection device provided by this utility model can inject fire extinguishing agent into any abnormal battery pack 8.1. When the distributed fire protection module 1 corresponding to the abnormal battery pack 8.1 malfunctions, the fire controller 6 can control other distributed fire protection modules 1 to inject fire extinguishing agent into the abnormal battery pack 8.1, which can greatly improve the reliability of fire prevention and response.

[0058] Preferably, in this embodiment 1, each valve 5 is an electrically controlled valve.

[0059] The sensor component 2 can be configured in various ways, as long as it can be installed inside the battery pack and monitor at least one of the temperature data, smoke data and gas data inside the battery pack, and can transmit the abnormal signal to the fire controller 6 through the control line 7 according to the monitored data when a fire occurs.

[0060] In one embodiment, sensor component 2 includes a smoke sensor.

[0061] In one embodiment, sensor assembly 2 includes a temperature sensor.

[0062] In one embodiment, sensor assembly 2 includes a gas sensor.

[0063] Preferably, in this embodiment 1, as Figure 1 As shown, the distributed fire protection module 1 is installed on one side of the corresponding battery cluster 8.

[0064] By installing the distributed fire suppression module 1 on one side of the corresponding battery cluster 8, the distance that the fire extinguishing agent needs to reach the battery pack 8.1 can be further reduced, enabling the distributed fire suppression device provided by this utility model to have a faster response speed when dealing with fires in battery energy storage systems.

[0067] The battery cluster 8 includes multiple battery packs 8.1, and each battery cluster 8 is set up in a one-to-one correspondence with each distributed fire protection unit of the distributed fire protection device.

[0068] The distributed fire-fighting device and energy storage system provided by this utility model have at least the following technical effects or advantages:

[0069] 1. Compared with existing battery energy storage fire protection devices, which require a large space for fire protection modules due to the centralized fire protection system, and which typically require a dedicated space outside the battery compartment for these modules, the distributed fire protection device provided by this invention can make reasonable use of the remaining space in the battery compartment by arranging each distributed fire protection module 1 inside the battery compartment and corresponding each distributed fire protection unit with each battery cluster 8 inside the battery compartment. This solves the problem of excessive space occupation in existing battery energy storage fire protection devices. Furthermore, in the event of a malfunction, only the malfunctioning distributed fire protection unit needs to be repaired and replaced individually, without the need for overall repair and replacement, which can effectively reduce maintenance costs.

[0070] Meanwhile, compared to existing battery energy storage fire-fighting devices that typically require fire-fighting modules to be placed outside the battery compartment, the distributed fire-fighting device provided by this utility model arranges each distributed fire-fighting module 1 inside the battery compartment. By utilizing fire-fighting pipelines 4 and valves 5, the fire extinguishing agent can reach the battery pack 8.1 via the shortest route, enabling the distributed fire-fighting device provided by this utility model to have a faster response speed when dealing with fires in battery energy storage systems.

[0071] 2.

Compared with the existing battery energy storage fire protection device, which usually sets valves 5 inside the pack, this method can save the space occupied by setting valves 5 inside the battery pack 8.1 by making reasonable use of the remaining space in the battery compartment, thus reducing the volume of the battery pack 8.1.

[0072] 3. By fixing the second nozzle 3 to the outer shell of the battery pack 8.1, the water outlet end of the second nozzle 3 extends into the outer shell of the battery pack 8.1, and the water inlet end of the second nozzle 3 extends out of the outer shell of the battery pack 8.1. Compared with the installation method of installing the nozzle entirely inside the battery pack 8.1, this method can save the space occupied by the nozzle being placed entirely inside the battery pack 8.1 and reduce the volume of the battery pack 8.1.

[0073] 4. By setting up the connecting pipeline 9, each distributed fire protection module 1 of the distributed fire protection device provided by this utility model can inject fire extinguishing agent into any abnormal battery pack 8.1. When the distributed fire protection module 1 corresponding to the abnormal battery pack 8.1 fails, the fire controller 6 can control other distributed fire protection modules 1 to inject fire extinguishing agent into the abnormal battery pack 8.1, which can greatly improve the reliability of fire prevention and response.
