By setting the semiconductor refrigerator 4 and the exhaust fan 9, it is only necessary to start the semiconductor refrigerator 4 and the exhaust fan 9 by controlling the switch 20, so that the cooled gas inside the temperature conducting coil 6 can be injected into the interior of the explosion-proof cabinet 2, which is convenient for the staff to dissipate heat and cool the electrical components inside the explosion-proof cabinet 2. The interior of the refrigeration bin 3 is provided with a temperature conducting coil 6, and the side of the refrigeration bin 3 is fixedly connected with an air filter 5, one end of the temperature conducting coil 6 is fixedly connected to the air filter 5, and the side of the explosion-proof cabinet 2 is fixedly connected. An exhaust port 8 is fixedly connected, an exhaust fan 9 is arranged inside the exhaust port 8, an exhaust pipe 10 is fixedly connected to the surface of the exhaust port 8, and a gas detector 11 is fixedly connected to the upper surface of the explosion-proof cabinet 2. By setting the gas detector 11 and the buzzer 12, it is only necessary to start the gas detector 11 through the control switch 20 to detect the gas concentration in the gas inside the coal mine in real time, and sound an alarm through the buzzer 12, so that the staff inside the coal mine can take timely protective measures. The side of the explosion-proof cabinet 2 is fixedly connected with the buzzer 12, and the temperature conducting coil 6 is passed through the interior of the explosion-proof cabinet 2. The other end of the temperature conducting coil 6 is fixedly connected to the air outlet 7, and the surface of the air outlet 7 is provided with a solenoid valve, and the surface of the exhaust pipe 10 is provided with a one-way valve 22.

[0026] By adopting the above technical solution, with the cooperation of the air filter 5 and the one-way valve 22, dust inside the coal mine is prevented from entering the interior of the explosion-proof cabinet 2, thereby achieving the effect of dustproofing the electrical components inside the explosion-proof cabinet 2.

[0027] Specifically, there are two groups of refrigeration bins 3, which are symmetrically arranged on both sides of the explosion-proof cabinet 2, and there are two groups of air extraction ports 8, which are symmetrically arranged on both sides of the explosion-proof cabinet 2. The lower surface of the mounting plate 1 is fixedly connected with a shock absorber 13.

[0028] Specifically, there are four shock absorbers 13 , which are arranged in a rectangular shape on the lower surface of the mounting plate 1 . The bottom end of the shock absorber 13 is fixedly connected to a universal wheel 14 , and a brake pad is provided on the side of the universal wheel 14 .

[0029] Specifically, a hinge 15 is fixedly connected to the surface of the explosion-proof cabinet 2 , and a movable door 16 is movably connected to the explosion-proof cabinet 2 via the hinge 15 . An observation window 21 is inlaid on the surface of the movable door 16 .

[0030] Specifically, the observation window 21 is made of a transparent material. A lock buckle 17 is provided on the surface of the movable door 16 . The explosion-proof cabinet 2 and the movable door 16 are fixedly connected via the lock buckle 17 .

[0032] The working principle of the present invention is as follows: when the present invention is in use, the device is first moved to a suitable position, and then the position of the universal wheel 14 is fixed by the brake pad, thereby preventing the device from shifting during use. When the staff uses the device to explosion-proof the electrical components inside the coal mine, the staff first starts the semiconductor refrigerator 4 and the exhaust fan 9 through the control switch 20. At the same time, the semiconductor refrigerator 4 starts to cool and cool the gas inside the temperature conducting coil 6, and the exhaust fan 9 discharges the high-temperature gas inside the explosion-proof cabinet 2 through the exhaust port 8, so that the cooled gas inside the temperature conducting coil 6 is injected into the interior of the explosion-proof cabinet 2, thereby starting to dissipate heat and cool the electrical components inside the explosion-proof cabinet 2. The staff starts the gas detector 11 through the control switch 20, which can detect the gas concentration in the gas inside the coal mine in real time. The gas detector 11 then transmits the detected data to the inside of the microprocessor. When the gas concentration inside the coal mine exceeds the normal range, the control switch 20 will start the buzzer 12 to sound an alarm, thereby facilitating timely protective measures for the staff inside the coal mine.
