Description

Technical Field

[0001] The utility model relates to the field of transportation, and specifically refers to an explosion-proof transport device for lithium batteries. Background Art

[0002] Electricity is a commonly used energy source nowadays. It is used in various fields of society because of its characteristics such as easy conversion of energy forms, low transmission loss and fast speed. In order to store electrical energy, people invented batteries. With the continuous development of science and technology, batteries have gradually developed from the original Daniel batteries to the most commonly used lithium batteries today. Although the existing lithium batteries have the characteristics of high voltage, long life and light weight, due to the high structural density of the lithium battery itself, it is very easy to explode once it encounters high temperature and severe vibration during transportation.

[0003] When transporting lithium batteries, existing explosion-proof transfer devices often set up transfer cabinets for transporting lithium batteries as multi-layer, mutually isolated battery trays. In order to prevent the lithium batteries from vibrating during transportation, elastic pads are usually placed in the battery compartment where the lithium batteries are placed for shockproofing. In order to prevent the lithium batteries from falling from the battery compartment during transportation, people will set a closed cover above the battery tray to prevent the lithium batteries from loosening.

[0004] Although this transfer device can ensure that lithium batteries will not experience strong vibrations during transportation, its highly sealed structure makes it extremely difficult for lithium batteries to dissipate heat during transportation. During transportation, the transfer cabinet continues to heat up due to external forces. Even if the transportation personnel discover and control the temperature of the transfer cabinet in time, due to its high sealing, it will cause the outside to be cold and the inside to be hot. Once the temperature is not completely lowered, the lithium batteries will ignite from the inside to the outside. Utility Model Content
