At the same time, the upper part of the first compartment is a partition, the upper left part of the partition is the second compartment, and the upper right part of the partition is the third compartment. A battery frame is provided inside the second compartment, and a lithium battery is installed inside the battery frame.

[0005] Preferably, a left cover is installed above the second compartment, and a right cover is installed above the third compartment.

[0006] Preferably, screw holes are provided at the edges of the left cover and the right cover, and the left cover and the right cover are fixedly connected to the upper part of the box body by bolts.

[0007] Preferably, handles are provided on the upper parts of the left cover and the right cover.

[0008] Preferably, the left side of the battery frame is higher than the right side, and handles are provided on both sides of the battery frame.

[0009] Compared with the existing technology, the beneficial effects of the utility model are: the mine-used explosion-proof and intrinsically safe lithium battery dual power switching control box is provided with a box body, a box door, a first compartment, a second compartment, a third compartment, a lithium battery and a battery frame. When the main power supply fails, it automatically switches to the backup power supply for power supply. When the backup power supply also fails, it automatically switches to the backup battery to ensure that one power supply is output at any time, ensuring the normal operation of the electrical equipment in the mine and providing protection for the mine workers to carry out normal work.
