At present, the power input module, power output device and power input device are placed under the same shell during use. After a single component in the equipment catches fire, the fire will spread to the entire interior, causing overall damage. At the same time, there will be a fixed cooling device installed in the equipment, which will hinder the work of maintenance personnel during maintenance. A Chinese patent discloses a "flameproof dual-power switching power box", and its application is "CN202222363837.5". It uses a first battery. When the flameproof power box needs to be repaired, the first battery is opened and the power is connected through the first ventilation hose. The flammable gas in the box body is sucked into the first gas storage box, and then the motor is started to drive the rotating shaft to rotate, the rotating shaft drives the rotating plate to rotate, the rotating plate drives the rotating column to rotate, and the rotating column drives the rotating short plate to rotate, so that the rotating short plate drives the second connecting plate to extend forward, so that the left door can be opened. At the same time, the rotating column drives the rotating long plate to rotate, and the rotating long plate drives the first connecting plate to rotate. The first connecting plate drives the right door to extend forward, so that the right door can be opened, making repairs convenient and less dangerous.
