[0016] Working principle: During operation, the support base plate 1 is first fixedly installed using mounting bolts with a diameter matching the mounting holes 2, thereby achieving the fixed installation of the entire equipment. Then, during use, three non-methane total hydrocarbon sampling gas bags are placed inside the three placement frames 10 respectively. The openings of the non-methane total hydrocarbon sampling gas bags are then fitted over the outside of the spherical nozzle 8 and clamped. Then, the air blower 4 is started to deliver hydrocarbon-removing air into the air outlet pipe 5. The hydrocarbon-removing air enters the interior of the non-methane total hydrocarbon sampling gas bags through the electrically controlled three-way valve 6, connecting pipe 7, and spherical nozzle 8. After the non-methane total hydrocarbon sampling gas bag is inflated, the gas injection is stopped. Then, the electrically controlled three-way valve 6 closes the passage to the outlet pipe 5 and opens the exhaust passage. At the same time, the regulating motor 13 starts, driving the regulating shaft 14 to rotate. The regulating shaft 14 drives the three transmission gears 15 on its outer side to rotate simultaneously. The transmission gears 15 drive the transmission rack 16 to move. The transmission rack 16 drives the positioning slider 21 to slide inside the positioning groove 20 inside the positioning frame 19, which can ensure better stability of the transmission rack 16 during movement. The moving rack 16 drives the movable frame 17 to move, which in turn drives the T-shaped frame 22 to move. The T-shaped frame 22 drives the positioning slide rod 23 to slide inside the positioning sleeve 24, ensuring better stability of the movable frame 17 during movement. Simultaneously, the movable frame 17 drives the movable plate 18 to move. The moving plate 18 compresses the non-methane total hydrocarbon sampling gas bag inside the placement frame 10, causing the gas injected into the non-methane total hydrocarbon sampling gas bag to be discharged through the exhaust port of the electrically controlled three-way valve 6. Then, the motor 13 is adjusted to rotate in the reverse direction to reset the movable plate 18. When the electric three-way valve 6 closes the exhaust port, it opens the passage to the exhaust pipe 5. The exhaust pipe 5 then injects gas into the non-methane total hydrocarbon sampling gas bag again through the electric three-way valve 6, connecting pipe 7, and ball nozzle 8. This cycle is repeated to clean the inside of the non-methane total hydrocarbon sampling gas bag three times. Then the cleaned non-methane total hydrocarbon sampling gas bag can be taken out. This allows the automatic cleaning equipment to clean multiple non-methane total hydrocarbon sampling gas bags at the same time during use, improving work efficiency and thus achieving better practicality.
