A protective net is installed on the rear side of the mounting shell 3 to filter impurities in the air. The left side of the mounting shell 3 is rotatably connected to the protective door 4. A combustible gas detector 5 is placed inside the mounting shell 3. The shape of the groove inside the mounting shell 3 is consistent with that of the combustible gas detector 5, which is convenient for placing the combustible gas detector 5. A motor 6 is installed on the base 1, and the output shaft of the motor 6 is connected to the connecting frame 2. The connecting frame 2 is connected to the rotating frame 7. The rotating frame 7 is symmetrically slidably connected to the mobile frame 8, and exhaust fans are installed on both mobile frames 8. 9, the exhaust fan 9 can extract the surrounding gas, the two exhaust fans 9 are connected to the opposite side with a hose 10 for conveying gas, the other end of the two hoses 10 are connected to a rotating ring 11, the bottom of the two rotating rings 11 are rotatably connected to the mounting shell 3, the rotating ring 11 can facilitate the rotation of the hose 10, the rotating frame 7 is symmetrically connected with a connecting plate 12, the two connecting plates 12 are slidably connected with a sliding frame 13, the bottom of the two sliding frames 13 are installed with a fixed block 14, the bottom of the two fixed blocks 14 are installed An anti-skid pad 15 is installed, and the bottom of the anti-skid pad 15 is in contact with the sliding frame 13. The anti-skid pad 15 can limit the sliding frame 13. A spring 16 is connected between the two fixed blocks 14 and the top of the corresponding connecting plate 12. An observation window 17 is embedded in the protective door 4 to observe the combustible gas detector 5. A plurality of limit blocks 18 are connected to the rear side of the observation window 17. The limit blocks 18 are in contact with the combustible gas detector 5. The limit blocks 18 can limit the combustible gas detector 5 to prevent it from moving.

When the combustible gas detector 5 detects combustible gas in the air, it will sound an alarm to prompt the staff to take corresponding measures. After completing the detection, turn off the combustible gas detector 5 and the motor 6.
