The lifting plate 12 is raised and adjusted by the screwing action of the screw and the fixing screw, so that the lifting plate 12 can drive the insertion rod 13 to slide out from the inside of the through hole 14, so as to discharge the liquid fire extinguishing agent for fire extinguishing. The connecting pipe 7 is provided to facilitate the replenishment of liquid fire extinguishing agent into the inner cavity 11.

[0028] In this embodiment, a flame-retardant layer 18 is fixedly installed on the outer wall of the roof 4 and the inner wall of the house 2. The flame-retardant layer 18 is a flame-retardant rock wool board. An axial flow fan 15 is fixedly installed on one side of the top of the house 2, corresponding to the bottom of the roof 4. The flame-retardant layer 18 can increase the heat preservation capacity of the analysis cabin, and the axial flow fan 15 can exhaust harmful gases inside the house 2 and replace the gas inside the house 2, thereby facilitating the operation of the equipment inside the house 2.

[0029] When using the analysis cabin for the oil and gas station, the combustible gas detector is model FIX900-Ex, the oxygen detector is model GCT-O2, and the flame detector is model GW800IR3. A hydrogen sulfide gas detector is installed inside the ventilation vent 6, corresponding to the interior of the cabin 2, to detect the harmful hydrogen sulfide gas and ensure safe operation of the analysis cabin. The online analyzer 9 is an online gas chromatograph. The analysis cabin is equipped with a sampling system, sample gas processing device, analysis unit, control and data processing unit, output unit, power distribution system, air conditioning, heating system, lighting system, venting system, and related facilities. An alarm is installed on the roof 4. All these systems and equipment are existing technologies. The detector group 10 detects the combustible gas, oxygen content, and hydrogen sulfide gas inside the analysis cabin. When the combustible gas content increases, the oxygen content decreases, or hydrogen sulfide gas is detected, an alarm is triggered, and the information is uploaded to the station control system. The axial flow fan 15 expels harmful gases from inside the building 2, replacing the gas inside the analysis cabin. When the detector group 10 detects a fire inside the analysis cabin, it notifies the operator to seal the outer end of the axial flow fan 15 with a rubber cover. The servo motor 8 and its supporting circuit drive the screw to rotate, and the screw connection between the screw and the fixed screw tube drives the lifting plate 12 to rise. At the same time, the solenoid valve at the top of the connecting pipe 7 is opened. The lifting plate 12 drives the insertion rod 13 and the vertical rod 16 to rise. The insertion rod 13 separates from the insertion hole 14, allowing the liquid fire extinguishing agent inside the inner cavity 11 to be discharged downward from the insertion hole 14. At the same time, the vertical rod 16 drives the adjusting plate 20 to slide and rise inside the fixed cover 19, and seals the ventilation opening 6 with a rubber pad to prevent air from continuing to enter the interior of the analysis cabin, facilitating fire extinguishing inside the analysis cabin and improving its practicality. The connecting pipe 7 facilitates the addition of liquid fire extinguishing agent to the bottom of the lifting plate 12 corresponding to the interior cavity 11. The interior of the two side walls of the roof 2 has through holes for installing pipes and cables, and rubber sleeves that can seal are fixedly installed between the pipes and cables and the through holes to increase the sealing between the pipes, cables and the roof 2; the outer sides of the vertical rod 16 and the plug rod 13 are fixedly installed with sealing rings corresponding to the inner walls of the roof 4 to improve the sealing of the inner cavity 11 and prevent leakage.
