AI Technical Summary
The existing package of stage power batteries is prone to aging, heat, fire, and heat dissipation holes in the protective box allow Mars to ignite external objects. If the heat dissipation hole is blocked, the smoke will not be able to circulate, resulting in changes in air pressure, which increases the harm.
A fire-proof isolation device is designed including a fireproof box, a heat dissipation port, an isolated fire door, a water tank and an exhaust pipe. An isolated fire door is installed on the heat dissipation port. When a fire occurs, the isolation fire door seals the heat dissipation port. The flue gas enters the water tank through the exhaust pipe. The liquid generates bubbles and consumes oxygen to prevent the fire from spreading, and the liquid passing through the water tank cools down.
Effectively prevent Mars from igniting external objects, preventing fire from spreading, and improving fireproof isolation effect and reducing safety hazards through smoke consumption and liquid cooling.

After decay, it is not enough to meet the current application power requirements of the equipment, but the battery is not broken. After some repairs and adjustments, it can be used in equipment that is downgraded to a lower level.
[0003] However, the existing second-life power battery packs still have the following problems during use:

Therefore, a protective box is generally installed on the second-hand power battery. However, the protective box is still equipped with heat dissipation holes for the second-hand power battery. In the event of a fire, sparks can still ignite external objects through the heat dissipation holes and the connecting lines of the second-hand power battery. If the heat dissipation holes of the installation box are blocked, although the protective box is fire-isolated, the smoke caused by the fire cannot be circulated and released, causing the air pressure inside the protective box to change, which is more likely to cause harm. Therefore, it is very necessary to involve a fire-proof isolation device for a second-hand power battery pack in the existing second-hand power battery protection field. Utility Model Content
