[0002] Atmospheric pollution refers to the phenomenon that various pollutants discharged into the atmosphere by human activities or natural processes exceed the carrying capacity of the atmospheric environment, leading to deterioration of air quality. The sources of pollutants are extensive, including fuel combustion in industrial production, chemical waste emission, and exhaust emission from vehicles and airplanes in the transportation field. These pollutants not only cause environmental problems such as acid rain and photochemical smog, but also destroy the ecological balance and pose a serious threat to human health, causing respiratory diseases and cardiovascular diseases. In order to effectively respond to atmospheric pollution, environmental monitoring devices need to be used for monitoring.

[0027] The working principle of this invention is as follows: First, the device adjusts the monitoring direction through the first adjustment component 8. The second motor 81 drives the small gear 82 to rotate, and the meshing large gear 83 rotates the rotating disk 9 via the transmission rod 84. Simultaneously, the pulley 85 at the bottom of the large gear 83 slides along the annular groove 86 of the base 1, providing stable support for the rotation. This allows the air detector 3 and the composite sensor 4 to flexibly align with different horizontal directions, ensuring comprehensive collection of atmospheric pollution data from all directions and avoiding monitoring blind spots. Second, the monitoring height is adjusted using the second adjustment component 10. The second motor 81 drives the first pulley 102 to rotate, which in turn drives the second pulley 104 and the second lead screws 105 on both sides to rotate via the transmission belt 103. This causes the second moving block 106 to slide the assembly frame 2 up and down. The contact wheel 12 tensions the transmission belt 103 to ensure stable transmission, allowing the air detector 3 and the composite sensor 4 to adapt to different atmospheric environments at different altitudes, meeting the pollution monitoring needs from low altitudes to certain altitudes and acquiring richer vertical pollution data. When the sensor needs cleaning, the repositioning component 5 starts working, and the first motor... 51 drives the first lead screw 52 to rotate, causing the first moving block 53 to slide along the guide groove 55 via the linkage block 54. This, in turn, moves the first cleaning component 6 and the second cleaning component 7 on the two supports 56 to the target position. Subsequently, the first cleaning component 6 performs wiping and cleaning. The water pump 65 supplies water to the wiping pad 61 through the corrugated pipe 64 and the water injection pipe 63. The elastic force of the spring 62 keeps the wiping pad 61 tightly attached to the sensor probe. The telescopic rod 67 ensures that the wiping process is stable and does not shift, removing dirt from the probe surface. The moistened wiping pad 61 improves the cleaning effect. To avoid dry wiping damaging the probe, the second cleaning component 7 is activated. The air pump 71 draws in air through the air inlet pipe 73, pressurizes it, and then sprays it out through the nozzle 72 to blow away residual dust and water droplets on the probe surface. This further cleans the probe, ensuring that the surface is dry and clean, preventing water droplets or residual dust from affecting the sensor's detection accuracy and ensuring the accuracy of subsequent monitoring data. Through the coordinated work of these steps, the device can flexibly adjust the monitoring position to obtain comprehensive data and automatically clean the sensor to maintain detection accuracy, thereby improving the efficiency of air pollution detection.

9. An air pollution detection device according to claim 8, characterized in that, A contact wheel (12) is rotatably connected to the side of the rotating disk (9) near the conveyor belt (103). One side of the contact wheel (12) is in contact with one side of the conveyor belt (103). A limit plate (13) is fixedly connected to the top of the contact wheel (12).

10. The monitoring method of the air pollution detection device according to claim 1, wherein the air pollution detection device according to any one of claims 1-8 is used, characterized in that, Includes the following steps: S1. Start the device power supply, check the operating status of the air detector (3), composite sensor (4), each motor and cleaning component, ensure that each component is connected normally, drive the assembly frame (2) to move to the initial monitoring height through the second adjustment component (10), and drive the first adjustment component (8) to drive the rotating disk (9) to reset to the initial angle; S2. Start the first adjustment component (8), the second motor (81) drives the small gear (82) to rotate, and through the meshing transmission with the large gear (83), the rotating disk (9) rotates slowly. The fixed frame (11) and the assembly frame (2) rotate synchronously with the rotating disk (9). During the rotation, the air detector (3) and the composite sensor (4) are aligned with the monitoring areas in different directions within a 360° range to achieve full coverage in the horizontal dimension. S3. Start the second adjustment component (10). The third motor (101) drives the second pulley (104) to rotate through the first pulley (102) and the conveyor belt (103), which drives the double screw to rotate synchronously, so that the second moving block (106) rises and falls along the inner side of the fixed frame (11). The assembly frame (2) moves with the second moving block (106) within the preset height range, stopping once every 0.5 meters. The air detector (3) collects the concentration of conventional particulate matter, and the composite sensor (4) records the data of special pollutants such as volatile organic compounds and heavy metals simultaneously, completing the vertical dimension layered monitoring. S4. During the monitoring process, when the preset cleaning cycle is reached or when abnormal fluctuations occur in the detection data, the monitoring is paused and the cleaning procedure is triggered. S5. By using the repositioning component (5) to drive the first cleaning component (6) and the second cleaning component (7) to move towards the air detector (3) and the composite sensor (4), the first cleaning component (6) cleans the air detector (3) and the composite sensor (4) once, and then the second cleaning component (7) cleans the air detector (3) and the composite sensor (4) a second time, thereby reducing the dirt on the probes of the air detector (3) and the composite sensor (4). S6. After cleaning is completed, the cleaning component is reset to its initial position by the repositioning component (5), the device restarts the monitoring function and continues to collect data. The system compares the monitoring data before and after cleaning.
