If the detected toxic gas content exceeds the preset range, the alarm mechanism 6 can be used to issue an alarm to remind the staff. In this technical solution, the toxic gas detection module 102 used is composed of a catalytic combustion sensor and an electrochemical sensor.

And during this process, the stabilizing block 202 can be driven by the connecting frame 203 fixedly connected to the surface of the lifting cylinder 301 to slide inside the stabilizing groove 201, so as to ensure the stable rotation of the detection frame 101. The first motor 303 can also be used to drive the threaded rod 304 to rotate, so as to drive the lifting column 302 to slide inside the lifting cylinder 301 by means of screw thread transmission on the surface of the threaded rod 304, so that the detection frame 101 is lifted to a suitable detection height.

And during this process, the stabilizing block 202 can be driven by the connecting frame 203 fixedly connected to the surface of the lifting cylinder 301 to slide inside the stabilizing groove 201, so as to ensure the stable rotation of the detection frame 101. The first motor 303 can also be used to drive the threaded rod 304 to rotate, so as to drive the lifting column 302 to slide inside the lifting cylinder 301 by means of screw thread transmission on the surface of the threaded rod 304, so that the detection frame 101 is lifted to a suitable detection height. When it is necessary to detect the surrounding air, the induced draft fan 401 can be used to generate suction, and then the surrounding air is extracted and conveyed into the detection frame 101 through the air inlet pipe 402. And the extracted air will filter the dust through the filter cylinder 403. The air inside the detection frame 101 can be discharged through the exhaust port 103. Then, the toxic gas detection module 102 can be used to detect the air passing through the inside of the detection frame 101. If it is detected that the content of the toxic gas exceeds the preset range, the alarm 602 fixedly installed at one end of the mounting frame 601 can be used to send an alarm to remind the staff.
