The rocker-type sampling device 20, the clean gas supply device 30, and the mixed gas detection device 40 are all connected to a control center 50 via a network. The rocker-type sampling device 20 includes a ring array arranged on the top of the mounting cover 10. Multiple support bases 21, a rocker arm 22 hinged to the top of the support bases 21, a sampling tube 23 slidably connected to the rocker arm 22, and a driving component 24 disposed on the outer wall of the mounting cover tube 10 for driving the multiple rocker arms 22 to swing; two shafts 231 are symmetrically provided on the outer wall of the sampling tube 23, and an electric disk 232 is provided on the outer wall of the shaft 231. The ends of the shafts 231 are connected to the rocker arms 22 through rollers 233; the electric disk 232 abuts against the rocker arms 22, and the driving component 24 includes symmetrical Two transmission rings 241 are located at the bottom of the rocker frame 22; two electric cylinders 242 are symmetrically arranged on the outer wall of the mounting cover tube 10; a lifting ring 243 is located at the actuating end of the electric cylinder 242; multiple U-shaped frames 244 are located on the lifting ring 243; and a transmission rod 245 is located on the outer wall of the U-shaped frame 244 and slidably connected to the inner ring of the transmission ring 241. The control center 50 is connected to the user terminal via a network. The control center 50 includes a sampling and detection module, an airflow cleaning module, and a cleaning analysis module. The sampling and detection module is used to trigger the rocker-type sampling device 20 and the gas mixing detection device 40 to detect the gas discharged through the installation cover 10; the airflow cleaning module is used to trigger the rocker-type sampling device 20, the cleaning gas supply device 30 and the gas mixing detection device 40 so that the gas supplied by the cleaning gas supply device 30 cleans the airflow inside the rocker-type sampling device 20 and the cleaning gas supply device 30; the cleaning analysis module analyzes the cleaning effect inside the rocker-type sampling device 20 and the gas mixing detection device 40.

[0022] It should be noted that in this embodiment, the rocker-type acquisition device 20, the clean gas supply device 30, and the mixed gas detection device 40 are all electrically connected to the sub-control center, which is connected to the control center 50 via a network. During installation, simply install the mounting cover 10 to the top of the chimney; When air quality testing is required, the sampling and testing module is used to trigger the rocker-type acquisition device 20 to move the sampling tube 23 to the sampling position, i.e., the inner ring of the mounting cover tube 10. At the same time, the gas mixing detection device 40 is triggered to draw in multiple sampling tubes 23 and mix the sample gas, and then detect particulate matter in the air after mixing. When system cleaning is required, the airflow cleaning module is used to trigger the rocker-type sampling device 20 to move the sampling tube 23 to the cleaning position, i.e., the position of the air supply seat 31. The gas mixing detection device 40 is turned on to perform self-cleaning using clean air. Furthermore, during the self-cleaning process of the detection system, the valve on the guide pipe 441 is closed, and the valve on the pipe between the guide pipe 441 and the airflow ring 322 is opened.

During this cleaning process, impurity particles in the entire system can be diverted to prevent all impurity particles from passing through the detection component 44, thereby reducing the risk of damage to the detection component 44. At this time, the cleaning analysis module receives the scattered light information received by the scattered light receiver, and obtains the first particulate matter information after analysis. When the first particulate matter information is less than the set value, that is, when the cleaning is completed in the detection component 44, the valve on the guide pipe 441 is opened and the valve on the pipe between the guide pipe 441 and the airflow ring 322 is closed, so that the gas passing through the entire system passes through the detection component 44. The cleaning analysis module receives the scattered light information received by the scattered light receiver, and obtains the second particulate matter information after analysis. When the second particulate matter information is less than the set value, it is determined that the cleaning is completed. Furthermore, when the rocker-type sampling device 20 is working, the actuator of the drive component 24 can drive the rocker frame 22 to swing, and the sampling tube 23 can move on the rocker frame 22 under the drive of gravity. When the sampling tube 23 moves to the designated position, the electromagnet 232 can use electromagnetic attraction to the rocker frame 22 to fix the sampling tube 23. Furthermore, when the drive component 24 is working, the actuator of the electric cylinder 242 drives the lifting ring 243 to rise and fall, the lifting ring 243 drives the U-shaped frame 244 to rise and fall, and during the process of the U-shaped frame 244 rising and falling, the transmission rod 245 slides in the transmission ring 241, and the rocker frame 22 swings through the transmission rod 245.

The gas in the air flow ring 322 can enter the supply air channel 313 through the pipeline, and then enter the sampling tube 23 through the supply air channel 313.

[0025] Please refer to the appendix carefully.

The outer wall of the redundant pipe 431 is connected to the clean gas source component 32 through a pipe.

[0026] It should be noted that, in this embodiment, when the gas mixing detection device 40 is working, the fan 42 is turned on, and the gas enters the gas mixing pipe 41 through the sampling pipe 23 and the pipeline. The gas mixing component 45 mixes the gas, and the mixed gas enters the exhaust pipe 43 through the fan 42. The detection component 44 draws in and detects the gas. The gas that is not drawn in by the detection component 44 is discharged through the residual gas discharge pipe 432. The metering pump 442 can ensure that the gas to be detected continuously enters the detection box 443 at a set flow rate, so as to accurately measure the particulate matter in the air. Furthermore, when the airflow mixing component 45 is working, the airflow is mixed once after passing through multiple guide plates 451. After the power motor 453 is turned on, it drives the impeller 452 to rotate, so as to achieve mechanical mixing of the airflow. Furthermore, when the detection component 44 is working, the metering pump 442 is turned on, and the metering pump 442 inputs the gas to be detected into the detection box 443 according to the set flow rate. When the gas passes through the laser emitter and the scattered light receiver, the laser emitter emits laser light, the scattered light receiver receives light information and transmits the light information to the control center 50, and the sampling and detection module in the control center 50 receives and analyzes the light information.

During installation, simply install the mounting cover 10 to the top of the chimney; When air quality testing is required, the sampling and testing module is used to trigger the rocker-type acquisition device 20 to move the sampling tube 23 to the sampling position, i.e., the inner ring of the mounting cover tube 10. At the same time, the gas mixing detection device 40 is triggered to draw in multiple sampling tubes 23 and mix the sample gas, and then detect particulate matter in the air after mixing. When system cleaning is required, the airflow cleaning module is used to trigger the rocker-type sampling device 20 to move the sampling tube 23 to the cleaning position, i.e., the position of the air supply seat 31. The gas mixing detection device 40 is turned on to perform self-cleaning using clean air. When the detection system is self-cleaning, the valve on the guide pipe 441 is closed, and the valve on the pipe between the guide pipe 441 and the airflow ring 322 is opened. The flushing gas from the rocker-type collection device 20 and the mixing pipe 41 is discharged through the exhaust pipe 43. During this cleaning process, impurity particles in the entire system can be diverted to prevent all impurity particles from passing through the detection component 44, thereby reducing the risk of damage to the detection component 44. At this time, the cleaning analysis module receives the scattered light information received by the scattered light receiver, and obtains the first particulate matter information after analysis. When the first particulate matter information is less than the set value, that is, when the cleaning is completed in the detection component 44, the valve on the guide pipe 441 is opened and the valve on the pipe between the guide pipe 441 and the airflow ring 322 is closed, so that the gas passing through the entire system passes through the detection component 44. The cleaning analysis module receives the scattered light information received by the scattered light receiver, and obtains the second particulate matter information after analysis. When the second particulate matter information is less than the set value, it is determined that the cleaning is completed. When the rocker-type sampling device 20 is working, the actuator of the drive component 24 can drive the rocker frame 22 to swing, and the sampling tube 23 can move on the rocker frame 22 under the drive of gravity. When the sampling tube 23 moves to the designated position, the electromagnet 232 can use electromagnetic attraction to the rocker frame 22 to fix the sampling tube 23. When the drive component 24 is working, the actuator of the electric cylinder 242 drives the lifting ring 243 to rise and fall, the lifting ring 243 drives the U-shaped frame 244 to rise and fall, and during the process of the U-shaped frame 244 rising and falling, the transmission rod 245 slides in the transmission ring 241, and the rocker frame 22 swings through the transmission rod 245. When the clean gas supply device 30 is working, when the sampling tube 23 moves into the limiting groove 311, the electromagnetic ring 312 is energized to adsorb and fix the sampling tube 23, the air pump 323 is turned on, and the air is filtered by the air filter 324 and then transmitted to the air flow ring 322 by the air pump 323. The gas in the air flow ring 322 can enter the air supply channel 313 through the pipeline, and then enter the sampling tube 23 through the air supply channel 313. When the gas mixing detection device 40 is working, the fan 42 is turned on, and the gas enters the gas mixing pipe 41 through the sampling pipe 23 and the pipeline. The gas mixing component 45 mixes the gas, and the mixed gas enters the exhaust pipe 43 through the fan 42. The detection component 44 draws in and detects the gas. The gas that is not drawn in by the detection component 44 is discharged through the residual gas discharge pipe 432. The metering pump 442 can ensure that the gas to be detected continuously enters the detection box 443 at the set flow rate, so as to accurately measure the particulate matter in the air. When the airflow mixing component 45 is working, the airflow is mixed once after passing through multiple guide plates 451. After the power motor 453 is turned on, it drives the impeller 452 to rotate, so as to achieve mechanical mixing of the airflow. When the detection component 44 is working, the metering pump 442 is turned on. The metering pump 442 inputs the gas to be detected into the detection box 443 according to the set flow rate. When the gas passes through the laser emitter and the scattered light receiver, the laser emitter emits laser light, the scattered light receiver receives light information and transmits the light information to the control center 50. The sampling and detection module in the control center 50 receives and analyzes the light information.
