Description
Technical Field
[0001] This utility model relates to the field of lithium battery storage technology, and in particular to a lithium battery storage device with a fireproof mechanism. Background Technology
[0002] With the rapid development of the new energy vehicle and energy storage industries, the safety issues of large-scale storage and transportation of lithium batteries are becoming increasingly prominent. Lithium batteries are prone to thermal runaway under conditions such as overheating, overcharging, or mechanical damage, which can lead to fires or even explosions. Therefore, there is an urgent need for a dedicated storage device with highly efficient fire-resistant functions. A lithium battery storage device with a fire-resistant mechanism is proposed to solve this key technical problem.
[0003] In existing technologies, common lithium battery storage devices often employ an external metal enclosure combined with internal fire-retardant materials. Some designs achieve flame retardancy by using a double-layered heat-insulating wall structure and filling the interlayer with inorganic refractory materials such as rock wool or aluminum silicate. Mechanically, most devices use a simple hinged lid with a manual latch for closure, with the battery internally isolated and protected by a fixed fire-resistant liner or a removable fireproof box. Some improved devices also incorporate a passive protection system with basic temperature monitoring sensors connected to an external fire-fighting interface.
[0004] However, existing technologies have the problem of not being able to quickly maintain fireproof linings. Existing fireproof structures are usually installed in an integral or bolted manner. When replacing fireproof linings, it is necessary to disassemble multiple connectors or even part of the box structure, which is cumbersome and time-consuming, seriously affecting the efficiency of equipment use and the continuity of fire protection. Summary of the Invention
[0005] To overcome the above shortcomings, this utility model provides a lithium battery storage device with a fireproof mechanism, aiming to improve the problem that the existing technology is not good at achieving rapid maintenance of the fireproof lining.
