The switch shaft 702 is installed on the switch handle 701 through the fixing bolt 10, and one end of the switch shaft 702 penetrates into the switch bushing 703. The radiator 4 is provided on the side away from the door cover 1, and the radiator 4 is installed on the first explosion-proof box body 2 through the fixing bolt 10. The first explosion-proof box body 2 is installed on the pry frame 6, and the first explosion-proof box body 2 is installed on the pry frame 6 through the fixing bolt 10. The second explosion-proof box body 201 is installed on the first explosion-proof box body 2, and the second explosion-proof box body 201 is welded to the first explosion-proof box body 2. The flange cover 3 is installed on the second explosion-proof box body 201, and the flange cover 3 is installed on the second explosion-proof box body 201 through the fixing bolt 10. The switch knob 9 is installed on the first explosion-proof box body 2, and one end of the switch knob 9 penetrates into the first explosion-proof box body 2.

[0025] The first flameproof enclosure 2 is installed on the skid frame 6 through the fixing bolts 10, so that the first flameproof enclosure 2 can be pulled to enable the skid frame 6 to slide on the ground. The door cover 1 is connected to the first flameproof enclosure 2 through four hinges 8. One end of the hinge 8 is installed on the door cover 1 through the fixing bolt 10, and the other end of the hinge 8 is installed on the first flameproof enclosure 2 through the fixing bolt 10. The second flameproof enclosure 201 is welded to the first flameproof enclosure 2. A battery pack is provided inside the first flameproof enclosure 2, and the wires of the battery pack are connected to the JD4 terminal block 5. The models of the terminal block 5 in this application are divided into the JF6 terminal block 5, the JD9 terminal block 5, and the JD4 terminal block 5. The JF6 terminal block 5 and the JD9 terminal block 5 are both installed inside the second flameproof enclosure 201, and one end of both the JF6 terminal block 5 and the JD9 terminal block 5 penetrates into the first flameproof enclosure 2, and the terminal blocks 5 of the models JF6 and JD9 are installed on the flameproof plate between the first flameproof enclosure 2 and the second flameproof enclosure 201 with two nuts. The JF6 terminal block 5 and the JD9 terminal block 5 are electrically connected to the JD4 terminal block 5, and five wiring ports are provided on the surface of the second flameproof enclosure 201. When in use, the power supply of the battery is turned off by the switch knob 9, and the fixing bolts 10 on the flange cover 3 at the top of the second flameproof enclosure 201 are removed with a screwdriver, and then the flange cover 3 is opened. The flange cover 3 is also made of explosion-proof material, and the wires are inserted into the second flameproof enclosure 201 through the wiring ports on the surface of the second flameproof enclosure 201, and the wires are installed on the JF6 terminal block 5 and the JD9 terminal block 5. When installed, the flange cover 3 is covered on the top of the second flameproof enclosure 201, and then fixed with the fixing bolts 10. Since the first flameproof enclosure 2 is in a sealed state when the door cover 1 and the flange cover 3 are closed, the battery can effectively isolate the combustible gas or dust from entering the connection between the battery, the wires and the terminal block 5 during operation, thus preventing the battery from exploding. And when a short circuit occurs at the connection between the wires and the JF6 terminal block 5 and the JD9 terminal block 5, causing a small amount of combustible gas or combustible dust inside the second flameproof enclosure 201 to explode, a small amount of combustible gas and combustible dust in the first flameproof enclosure 2 and the second flameproof enclosure 201 enter when the door cover 1 or the flange cover 3 is opened. The second flameproof enclosure 201 will block the explosion to protect the battery and prevent the explosion from affecting the external combustible gas and causing a secondary explosion. And since the battery is installed on the first flameproof enclosure 2, when the battery fails and explodes, the explosion will be blocked by the first flameproof enclosure 2 to prevent the explosion from affecting the external combustible gas and causing a secondary explosion. When in normal use, the battery pack can be turned on by rotating the switch knob 9. A bushing and a bush are provided at the connection between the rotating shaft of the switch knob 9 and the first flameproof enclosure 2. The bushing and the bush will protect the rotating shaft of the switch knob 9 and can effectively reduce the wear of the rotating shaft. When the switch knob 9 is rotated clockwise, the total circuit of the battery module is connected, enabling the battery module to supply power to the JD4 terminal block 5. An electrical switch 7 is provided on the top of the switch knob 9,The electrical switch 7 includes a switch handle 701, a switch shaft 702, and a switch bushing 703. One end of the switch bushing 703 penetrates into the interior of the first explosion-proof housing 2. The switch bushing 703 serves to reduce the wear of the switch shaft 702, and the switch bushing 703 is mounted on the first explosion-proof housing 2 by fixing bolts 10. The switch shaft 702 is mounted on the switch handle 701 by fixing bolts 10, and one end of the switch shaft 702 penetrates into the switch bushing 703 and is connected to the circuit controller inside the first explosion-proof housing 2. Thus, when the switch handle 701 is rotated clockwise, the switch handle 701 drives the switch shaft 702 to rotate, causing the switch shaft 702 to drive the controller inside the first explosion-proof housing 2 to rotate, thereby closing the circuit and allowing current to flow through, thus turning on the circuit. When the circuit is turned on, the current of the battery is transmitted to the JF6 terminal 5 and the JD9 terminal 5 through the JD4 terminal 5. Since the power cord of the external device is connected to the JF6 terminal 5 and the JD9 terminal 5, the battery can supply power to the external device. During the power supply process, the battery generates heat, and this heat is dissipated by the radiator 4 on the back of the first explosion-proof housing 2. The radiator 4 is mounted on the first explosion-proof housing 2 by fixing bolts 10, and one end of the radiator 4 penetrates into the interior of the first explosion-proof housing 2. The radiator 4 absorbs the heat dissipated by the battery and transfers the heat to the fins of the radiator 4, and the heat is dissipated into the air through the contact of the fins on the surface of the radiator 4 with the air., Specific Embodiment Two:

[0027] Referring to Figures 1-5 , for a mine explosion-proof lithium-ion battery device, further based on the basic structure in Specific Embodiment One, two mounting brackets and an arc-shaped connecting bracket can be provided on the surface of the first explosion-proof housing 2. The two mounting brackets are in a parallel state and are mounted on the first explosion-proof housing 2 by fixing bolts 10. The mounting brackets are provided on the side away from the switch knob 9. The arc-shaped connecting bracket is mounted on the mounting bracket by a hinge. In this way, the combustible gas detector can be clamped between the two mounting brackets. At this time, the arc-shaped connecting bracket is rotated so that the other end of the arc-shaped connecting bracket abuts against the other mounting bracket and the arc-shaped connecting bracket is fixed to the other mounting bracket with fixing bolts 10 to complete the installation of the combustible gas detector. When connecting the circuit, the combustible gas detector can be used to observe the concentration of combustible gas in the current air to ensure whether the environment is safe when detecting and connecting the circuit.

[0028] In summary:

[0029] 1. The door cover 1 is connected to the first explosion-proof box body 2 through a hinge 8. One end of the hinge 8 is installed on the door cover 1 through a fixing bolt 10, and the other end is installed on the first explosion-proof box body 2 through a fixing bolt 10. The second explosion-proof box body 201 is welded to the first explosion-proof box body 2. A battery pack is arranged inside the first explosion-proof box body 2, and the wires of the battery pack are connected to the JD4 terminal 5. The models of the terminals 5 are divided into JF6 terminals 5, JD9 terminals 5 and JD4 terminals 5. One ends of the JF6 terminal 5 and the JD9 terminal 5 both penetrate into the first explosion-proof box body 2. The JF6 terminal 5 and the JD9 terminal 5 are electrically connected to the JD4 terminal 5. And a wiring port is arranged on the surface of the second explosion-proof box body 201. When in use, the wires enter the inside of the second explosion-proof box body 201 from the wiring port on the surface of the second explosion-proof box body 201 and are installed on the JF6 terminal 5 and the JD9 terminal 5. Since the first explosion-proof box body 2 is in a sealed state when the door cover 1 and the flange cover 3 are closed, it can effectively isolate the combustible gas or dust from entering the connection between the battery, the wires and the terminal 5, thus preventing the battery from exploding. And when a short circuit occurs at the connection between the wires and the JF6 terminal 5 and the JD9 terminal 5 and causes a fire, triggering an explosion of the residual combustible gas or combustible dust inside the second explosion-proof box body 201, the second explosion-proof box body 201 will block the explosion to protect the battery and prevent the explosion from affecting the external combustible gas and causing a secondary explosion. And since the battery is installed on the first explosion-proof box body 2, when the battery fails and explodes, the explosion will be blocked by the first explosion-proof box body 2 to prevent the explosion from affecting the external combustible gas and causing a secondary explosion, solving the drawbacks that the battery has no explosion-proof box body and the terminal 5 is arranged outside and in contact with the air.
