TECHNICAL FIELD

[0001] The utility model relates to electrochemistry energy storage field especially, a kind of electrochemistry energy storage cabinet integrated automatic fire extinguishing system. BACKGROUND

[0002] China's energy storage industry is growing rapidly, and electrochemical energy storage applications are becoming more and more common. Electrochemical energy storage cabinets have relatively small volume, high integration, less influence from geographical factors, flexible application scenarios, short construction period, fast response speed, relatively mature technology, high energy density, and high conversion efficiency. They are widely used in power generation, power transmission, power distribution, and power consumption. However, lithium-ion batteries used for energy storage in electrochemical energy storage cabinets are essentially chemical components containing high-energy substances, which have inherent dangers. Therefore, a complete and specialized fire extinguishing system must be installed. Due to the high integration and limited internal space of electrochemical energy storage cabinets, conventional fire extinguishing equipment cannot be integrated at a high enough level and occupies too much space, making it difficult to meet the installation requirements for high-integration electrochemical energy storage cabinets. To improve energy density and charge-discharge efficiency, current electrochemical energy storage cabinets generally use liquid-cooled battery packs as energy carriers. Conventional fire extinguishing equipment cannot accurately locate and suppress fires in battery packs. SUMMARY

[0003] The utility model aims at overcoming the problems of conventional fire extinguishing equipment that is not convenient to match with electrochemical energy storage cabinets and has defects in suppressing fires in electrochemical energy storage cabinets. It provides an electrochemical energy storage cabinet integrated automatic fire extinguishing system. This system is designed specifically for electrochemical energy storage cabinets and integrates detection, control, and fire extinguishing functions into one unit, which is small in size and highly standardized. It solves the problem of large space occupation and non-standardization when configuring fire extinguishing systems for electrochemical energy storage cabinets. This system can also accurately spray fire extinguishing agents to battery packs with fires through selection group valves and branch pipes, accurately suppress battery fires, and improve the safety level of electrochemical energy storage cabinets. The application of this system can also reduce the design, production, and debugging costs of electrochemical energy storage cabinets, achieve product production standardization, save costs, and save project implementation time.
