[0026] When the device is used for monitoring carbon dioxide, the first sealing seat 1, the second sealing seat 3 and the sensor probe 11 are simultaneously inserted into the surface opening of the object to be detected. After the insertion, the airbags 4 on the first sealing seat 1 and the second sealing seat 3 can be injected with gas. The airbags 4 expand and seal the interior of the device's insertion port. In conjunction with the rotation adjustment of the lifting tube 7, the air cushion 9 at the bottom of the squeezing seat 8 can squeeze the outside of the device's insertion port, thereby achieving a sealed effect after the device is inserted. After the device is inserted and used, the airtightness of the sensor probe 11 during the insertion sensing is guaranteed to ensure the accuracy of the device's detection work. The sensor probe 11 uses a concentration detection probe structure already available in the prior art.

[0027] Among them, a spiral gas transmission pipe 12 is fixedly installed on the inner walls of the first sealing seat 1 and the second sealing seat 3, a partition plate 13 is fixedly installed on the inner walls of the first sealing seat 1 and the second sealing seat 3, two air inlet pipes 14 are inserted into the interior of the dredging pipe 5, and the air outlet ends of the air inlet pipes 14 are fixedly connected to the air inlet ends of the spiral gas transmission pipe 12. The partition plate 13 is close to the airbag 4, and the air outlet end of the spiral gas transmission pipe 12 is connected to the interior of the partition plate 13;

[0028] By externally connecting the input end of the air inlet pipe 14 to a gas transmission device for gas input, after the gas enters, it can enter the interior of the airbag 4 through the spiral gas transmission pipe 12. The setting of the spiral gas transmission pipe 12 can extend the gas transmission process to ensure uniform gas injection during the gas transmission process.

[0029] Please refer to Figure 2 、 Figure 4 and Figure 5 , a small sensor device for carbon dioxide concentration monitoring;

[0030] Among them, a docking pipe 15 is fixedly installed at the bottom of the first sealing seat 1, and the top outer surface of the connecting pipe 10 is threadedly connected to the interior of the docking pipe 15;

A shunt pipe 17 is fixedly installed at the top of the dredging pipe 5, and a partition piece 18 is fixedly installed on the inner wall of the shunt pipe 17;

[0033] Through the installation of the shunt pipe 17 on the dredging pipe 5, when the air inlet pipe 14 and the sensing wire 16 penetrate through, they can be wrapped and separated to avoid the intersection of the lines.
