[0002] Smoke and flue gas collection is an important part of environmental monitoring, which involves monitoring particulate matter and gaseous pollutants in waste gas emitted from fixed pollution sources. In recent years, the prevention and control of air pollution has received more and more attention from the country. In the production process of some factories, it is inevitable to emit flue gas into the air. In order to detect whether the emitted flue gas meets the relevant national standards, it is necessary to use flue gas sampling equipment for sampling, so as to facilitate the subsequent detection of the collected flue gas samples. The existing portable smoke sampling equipment generally includes a main unit, a sensor and a sampling gun. When sampling the smoke inside the chimney, the sampling personnel need to hold the sampling gun to take the sample, which requires the sampling personnel to face the chimney, which is very harmful to the sampling personnel.

A smoke and flue gas sampling method, applied to a smoke and flue gas sampling device according to claim 5, characterized in that: include: Step 1: Connect the sampling gun body (1) and the smoke sampler to each other, and then move them to the side of the smoke outlet, then lift the sampling gun body (1) to send the moving mechanism (2) to the inside of the smoke outlet, pull the blocking piece (310) to drive the connecting shaft (37) to move, and at the same time press the third spring (311) to relax, use the connecting shaft (37) to pull the push ring (34) and then pull the insert (35) out from the inside of the socket (216), at this time the fourth spring (313) will pop out, and use the top plate (312) to push the installation tube (21) to the inside of the smoke outlet; Step 2: When the installation tube (21) moves toward the inside of the chimney, it pulls the air pipe (25) off the winding shaft (24), and at the same time, the first spring (213) pushes the pressing plate (214) upward, driving the second slide tube (210) upward. After the second slide tube (210) moves to a certain position, it pulls the slide bar (29) upward, and then drives the sensor (212) upward through the connecting tube (211), ensuring that the sensor (212) can measure the smoke at the moving height, and then the smoke dust collector is started to collect the smoke inside the chimney; Step 3: After the measurement is completed, the plug (215) is rotated to drive the winding shaft (24) to rotate, so that the air pipe (25) is rewound onto the winding shaft (24), and then the plug (215) is inserted into the inner side of the insert tube (31) so that the insert sheet (35) is re-inserted into the inner side of the socket (216) to fix the installation tube (21), and at the same time, the pressing sheet (214) is clamped under the rotating plate (43), and the spring sheet (47) is used to drive the rotating shaft (46) to rotate downward, so that the rotating plate (43) presses the pressing sheet (214) to prevent the first spring (213) from accidentally springing up.
