[0026] Working principle: When the utility model is used, the user monitors the parameters of the flue gas discharged from the chimney 2 through the gas monitor 5, and can master the parameters of the flue gas discharged from the chimney 2, so that the staff can quickly take further measures when the flue gas discharged does not meet the environmental protection standards.

If the gas monitor 5 needs to be installed again, refer to the above steps, and after the slide rod 10 enters the circular hole 11 through the rectangular opening 13, loosen the slide rod 10, so that the rebound force of the spring 15 drives the columnar block 12 to reset through the circular plate 14 and the slide rod 10 and insert it into the inner cavity of the circular hole 11, so that the gas monitor 5 can be installed on the bottom of the top plate 4 again, realizing real-time monitoring of the gas parameters of the exhaust gas through the gas monitor installed at the top of the chimney.

At the same time, the coordinated use of the insertion rod 6 and the hole block 7 can further ensure the stability of the installation of the gas monitor 5, so that the gas parameters of the exhaust flue gas can be monitored in real time through the gas monitor installed at the top of the chimney.
