Therefore, there is a need for an explosion-proof lithium battery pack for special operation that can prevent explosion and impact, reduce the impact of vibration on the battery pack, and also take heat dissipation into account, so as to solve the problem that the conventional lithium battery pack cannot cope with.

Taking an example of the first embodiment, when the lithium battery pack is used, the explosion-proof sliding baffle 103 on the explosion-proof wave absorbing device 1 is manually slid down from the explosion-proof fixed baffle 106, then the explosion-proof sliding baffle 103 is adsorbed on the explosion-proof magnetic attraction fixed block 102, thereby realizing the wave absorbing and shock resisting functions through the explosion-proof sliding baffle 103 and the explosion-proof fixed baffle 106, then the damping function of the lithium battery pack is realized through the damping function of the damping and shock absorbing component 401 on the energy absorbing and shock absorbing device 4 when the explosion operation occurs in a mine, meanwhile, the temperature inside the lithium battery pack and the pressure value generated by the expansion of the battery are monitored in real time through the temperature internal pressure monitoring component 402, so that the real-time monitoring of the battery is realized, when the temperature of the single lithium battery 403 is too high, the water-cooling heat exchanging component 305 on the water-cooling circulation device 3 can exchange heat with the single lithium battery 403, and then the air exhausting fan 304 discharges heat from the unidirectional air exhausting component 201 on the air exhausting device 2, thereby realizing the heat dissipation function.
