[0002] With the transformation of the global energy structure towards cleaner and lower-carbon forms, energy storage technology has become one of the key means to address the volatility of renewable energy, improve grid stability, and enhance energy utilization efficiency. As a modular and scalable energy storage solution, containerized energy storage systems have been widely applied and developed rapidly in recent years.

[0003] However, in the event of emergencies such as system failures, thermal runaway, or fires in existing energy storage systems, it is often difficult to quickly and accurately locate the faulty modules. The fire extinguishing system usually adopts a full-box sprinkler design, lacking module-level linkage control, resulting in waste of fire-fighting resources and serious damage to non-faulty areas. This not only increases the maintenance and replacement costs but also causes great difficulties in accident traceability and liability attribution. Once an accident occurs, it is easy for all parties to shift the blame to each other, affecting the efficiency of accident handling and the fairness of liability tracing. Summary of the Utility Model

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figures 1-3 An embodiment of this utility model provides: a containerized energy storage system, including a container body 1, a fire extinguishing agent tank 2 fixedly connected to the inner wall of the container body 1, a rigid pipe 3 fixedly connected to the output end of the fire extinguishing agent tank 2, a solenoid valve 4 fixedly connected to the outer wall of the rigid pipe 3, a nozzle 5 fixedly connected to the output end of the rigid pipe 3, a flexible hose 6 fixedly connected to the inside of the rigid pipe 3, a nozzle 7 fixedly connected to the output end of the flexible hose 6, a detector 8 fixedly connected to the outer wall of the rigid pipe 3, an explosion-proof fan 9 fixedly connected to the inside of the container body 1, an exhaust fan 10 fixedly connected to the inside of the container body 1, a fire extinguishing interface 11 fixedly connected to the inner wall of the container body 1, a fire extinguishing pipe 12 fixedly connected to the inside of the fire extinguishing interface 11, and an energy storage component provided on the inner wall of the container body 1;

[0026] Specifically, the container body 1 provides fixed support for the fire extinguishing agent tank 2, which contains perfluorohexanone. When the fire extinguishing agent tank 2 is opened, the fire extinguishing agent can be delivered to the rigid pipe 3. The rigid pipe 3 provides fixed support for the solenoid valve 4 and the hose 6. Simultaneously, the fire extinguishing agent inside the rigid pipe 3 can be delivered to the hose 6. The fire extinguishing agent inside the rigid pipe 3 and the hose 6 can be sprayed out through nozzles 1 and 2 to extinguish the fire. At the same time, the rigid pipe 3 provides fixed support for the detector 8. The detector 8 is a three-in-one detector, including smoke, heat, and combustible gas detection. Each energy storage module 14 is equipped with a detector 8 and a solenoid valve 4. When a detector 8 detects that the smoke or heat inside exceeds the threshold, it will control the corresponding solenoid valve 4 to activate, controlling the nozzle 2 7 at the corresponding detector 8 to open and spray the fire extinguishing agent, thus accurately locating the fault point and... In addition, when the detector 8 in the middle of the cabinet detects that the smoke and temperature inside the entire cabinet exceed the set threshold, the sprinkler head 5 can be activated to spray extinguishing agent throughout the cabinet. At the same time, the detector 8 in the middle can also open the fire extinguishing interface 11, which is connected to the fire water pipe. When the fire extinguishing interface 11 is opened, the water inside can enter the fire extinguishing pipe 12 and be sprayed through the sprinkler head of the fire extinguishing pipe 12. Through the simultaneous spraying of water and extinguishing agent, the system can achieve full coverage fire extinguishing. At the same time, when the detector 8 detects that the combustible gas exceeds the set threshold, the explosion-proof fan 9 and the exhaust fan 10 can be activated to draw air from the outside in and replace the internal gas. By independently detecting fire extinguishing in each area, not only can the source of the fault be accurately identified and the responsible party be clearly identified, reducing mutual shirking and disputes, but also targeted fire extinguishing can avoid large-scale fire extinguishing accidents and reduce maintenance and replacement costs.

[0027] Reference Figure 2 The energy storage component includes a control module 13, the lower surface of which is fixedly connected to the inner wall of the container body 1, and the upper surface of which is electrically connected to an energy storage module 14.

[0028] Specifically, the container body 1 can provide fixed support for the control module 13, and the control module 13 can issue control commands to the energy storage module 14. At the same time, the energy storage module 14 can store electricity. Each control module 13 is equipped with eight energy storage modules 14, and there are a total of six control modules 13, which are divided into six energy storage areas.

[0029] Reference Figure 2 and Figure 4 A hoisting shaft 15 is fixedly connected to the outer wall of the container body 1, and a grounding point 16 is fixedly connected to the outer wall of the container body 1; a power distribution cabinet 17 is fixedly connected to the inner wall of the container body 1, and a wire trough 18 is provided inside the power distribution cabinet 17, with the outer wall of the wire trough 18 fixedly connected to the inner wall of the container body 1.

[0030] Specifically, the container body 1 can provide fixed support for the lifting shaft 15 and the grounding point 16. The lifting shaft 15 can provide a stable force point during the lifting process, which is convenient for construction, lifting and handling. The grounding point 16 plays a role in grounding protection. When a leakage fault occurs, the current can be quickly guided to the ground through the grounding point 16 to avoid electric shock to the operators. The container body 1 can also provide fixed support for the power distribution cabinet 17. The power distribution cabinet 17 can be connected to the mains power and supply power to various electrical devices from the top of the container through the cable tray 18.

[0031] Reference Figure 5 An air conditioner 19 is fixedly connected inside the container body 1, and a liquid cooling unit 20 is fixedly connected to the inner wall of the container body 1; a liquid cooling pipe 21 is installed inside the liquid cooling unit 20, and a liquid cooling pipe 22 is fixedly connected inside the liquid cooling pipe 21; a liquid cooling pipe 23 is fixedly connected inside the liquid cooling pipe 22, and the outer walls of the liquid cooling pipes 22 and 23 are set on the outer wall of the energy storage module 14; a liquid cooling interface 24 is fixedly connected to the outer wall of the liquid cooling pipe 23.

[0032] Specifically, the air conditioner 19 can control the temperature of the electrical compartment to maintain it at the optimal working environment temperature. The container body 1 can provide fixed support for the liquid cooling unit 20. The liquid cooling unit 20 can cool the liquid and transport the cooled liquid to the interior of the first liquid cooling pipe 21. The fire extinguishing agent tank 2 then transports the liquid to the second liquid cooling pipe 22. The liquid is then transported to each energy storage area and then to each layer of energy storage module 14 through the third liquid cooling pipe 23. Each layer of energy storage module 14 is equipped with a liquid cooling plate. The liquid is connected to the liquid cooling plate through the liquid cooling interface 24, and the liquid is transported to the interior of the liquid cooling plate to remove the heat from the energy storage module 14. This achieves the goal of controlling the entire system to work in the optimal environment. The liquid cooling unit 20 integrates the overall heat dissipation system, accurately controls the overall temperature, and distributes the coolant through branch pipes. This eliminates the need for an independent heat dissipation system in each energy storage area, significantly reducing the complexity of the system and reducing energy consumption and cost.

[0033] Working principle: When the system is needed, the extinguishing agent tank 2 is opened first. Then, the detectors 8 in each energy storage area are used for detection. When the detector 8 detects that the smoke or temperature in the area exceeds the threshold, the solenoid valve 4 of that area can be controlled to open the sprinkler head 7 of that area to spray the extinguishing agent, accurately finding and eliminating the fault point. When the detector 8 in the container detects that the smoke or temperature in the entire container exceeds the threshold, the solenoid valve 4 in the middle is controlled to open the sprinkler head 5 to spray the extinguishing agent in the entire container. At the same time, the fire interface 11 is opened, and fire water is delivered to the fire pipe 12 through the fire interface 11. The sprinkler head of the fire pipe 12 sprays water into the entire container body 1 to achieve overall fire extinguishing. By independently detecting fire in each energy storage area, the source of the fault can be accurately identified, the responsible party can be clarified, and the phenomenon of mutual shirking of responsibility and disputes can be reduced. It can also avoid large-scale fire extinguishing accidents and reduce maintenance and replacement costs.

[0034] When cooling is required, the air temperature in the electrical compartment area is first regulated by the air conditioner 19 to assist in heat dissipation. Then, the liquid cooling unit 20 is turned on to cool the liquid and deliver the cooled liquid to the interior of the first liquid cooling pipe 21. From there, the liquid is distributed to the second liquid cooling pipe 22 in each energy storage area. Simultaneously, the liquid is distributed to the third liquid cooling pipe 23 in each layer for further subdivision. The third liquid cooling pipe 23 then delivers the liquid through the liquid cooling interface 24 to the liquid cooling plate inside the energy storage module 14. The liquid cooling plate removes the heat from the energy storage module 14, thus controlling the entire system to operate in the optimal environment. The liquid cooling unit 20 controls and integrates the overall heat dissipation system, eliminating the need for an independent heat dissipation system in each energy storage area, significantly reducing system complexity, energy consumption, and cost.
