s1, when the device is used, the electric telescopic rod (31) can be controlled to work through the control panel (9), the fixing frame (32) and the universal wheels (34) are pushed to move downwards through the electric telescopic rod (31), so that the device is integrally supported through the universal wheels (34), and then the device can be moved through the universal wheels (34) to a designated position;
s2, introducing the discharged tail gas into the air inlet pipe (10) through an external pipeline, simultaneously opening the valve (11), allowing the tail gas to enter the sampling box (4) through the air inlet pipe (10), simultaneously pushing the piston (12) to move upwards in the sampling box (4), discharging the rest of the gas in the sampling box (4) through the exhaust pipe (16), simultaneously extruding the first return spring (14), continuously introducing the tail gas into the sampling box (4) after the first return spring (14) cannot be extruded any more, extruding the baffle plate (187) by the tail gas, extruding the second return spring (188), and allowing the tail gas to enter the communication groove (183) through the detection hole (17) and the air inlet hole (182) after the baffle plate (187) is separated from the air inlet hole (182);
s3, enabling the tail gas entering the communicating groove (183) to enter the communicating pipe (191), meanwhile pushing the blades (193) and the rotating pipe (192) to rotate, enabling the tail gas to enter the rotating pipe (192) through the through hole (194), discharging the tail gas through the rotating pipe (192), driving the knocking rod (195) and the knocking block (196) to rotate while the rotating pipe (192) rotates, and enabling the knocking block (196) to continuously knock the knocking ball (199) to give out crisp knocking sound so as to remind surrounding workers;
s4, after hearing the knocking sound, the worker closes the valve (11), the introduction of tail gas is stopped, the baffle (187) returns under the action of the second return spring (188), the air inlet hole (182) is blocked again, and at the moment, the inside of the sampling box (4) and the collected tail gas are arranged below the piston (12).
