Accurately monitoring the concentration of atmospheric particulate matter is of great significance for environmental governance, air quality assessment, and public health protection.

[0003] For traditional monitoring devices, under different wind speed conditions, the wind speed at the air inlet cannot be automatically adjusted, resulting in too fast air inlet speed in a strong wind environment, which may cause particulate matter to rebound or deposit inside the monitoring device, affecting the monitoring accuracy; while in a weak wind environment, the air intake is insufficient and cannot meet the monitoring requirements.

[0014] The beneficial effects achieved by the present invention with the above structure are as follows:

[0015] (1) To solve the problem that the wind speed at the air inlet of the atmospheric particulate matter concentration monitoring device used on the market at present cannot be automatically adjusted according to the intensity of the external wind force, which affects the monitoring accuracy and cannot meet the monitoring requirements, the present invention sets an adjustable support assembly, a particulate matter monitoring assembly, and a wind speed self-adaptive adjustment assembly, so that the device can adaptively adjust the air inlet area of the air inlet according to the strength of the external wind force, and then realize the self-adaptive adjustment of the wind speed, avoid the rebound or deposition of particulate matter inside the monitoring device, and improve the monitoring accuracy.

[0016] (2) Through the wind speed self-adaptive adjustment assembly, the device can automatically adjust the distance between the air inlet baffles according to the external wind speed, so as to realize the dynamic adjustment of the air inlet wind speed. In a strong wind environment, the distance between the baffles increases, reducing the air inlet wind speed to prevent the rebound or deposition of particulate matter; in a weak wind environment, the distance between the baffles remains small to ensure sufficient air intake, effectively improving the adaptability and monitoring accuracy of the monitoring device under different wind speed conditions.

[0017] (3) The device is equipped with a wind vane and a rotating support structure, which can automatically adjust the inlet direction of the monitoring device housing according to the wind direction, making it always face the wind direction directly. This maximally ensures the normal inflow of air into the monitoring device, improves the intake efficiency, avoids the interference of crosswind or headwind on the monitoring results, and enhances the stability and reliability of the monitoring.

[0018] (4) A ventilation filter and a desiccant box are arranged inside the monitoring device. Before the air enters the monitoring device, it is filtered by the filter to remove large particle impurities. After entering the device, the air contacts the desiccant to reduce the humidity, preventing particulate matter from caking or adhering to the detection element. This improves the sensitivity and accuracy of the particulate matter detector, extends the service life of the equipment, and reduces the maintenance cost. BRIEF DESCRIPTION OF THE DRAWINGS

The desiccant box 206 is fixedly connected to the inner surface of the monitoring device housing 203. The breathable mesh plate 207 is detachably connected to the desiccant box 206.

[0037] The adjustable support assembly 1 includes a main support sleeve 101, a lifting rod 102, a fixing ring 103, a connecting plate 104, a rotating rod 105, a first rotating shaft 106, a sliding support 107, a convex block 109, a locking nut 110, a second rotating shaft 111, a positioning plate 112, and a fastening bolt 113. The lifting rod 102 is slidably connected to the inside of the main support sleeve 101. The fixing ring 103 is fixedly connected to the lifting rod 102. The connecting plate 104 is fixedly connected to the fixing ring 103. The top end of the rotating rod 105 is disposed between the connecting plates 104. The first rotating shaft 106 passes through and rotatably connects the connecting plates 104. The rotating rod 105 is rotatably connected to the first rotating shaft 106. The sliding support 107 is slidably connected to the rotating rod 105. A limiting chute 108 is provided on the sliding support 107. The convex block 109 is fixedly connected to one end of the rotating rod 105 away from the connecting plate 104. The convex block 109 is slidably connected to the limiting chute 108.

The fastening bolt 113 passes through and is threadedly connected to the positioning plate 112.

[0038] The synchronous gear 312 is meshed with the follower gear 314. The height of the first driving pulley 316 is the same as the height of the follower pulley 319. The height of the driving pulley 313 is the same as the height of the connecting pulley 323. The height of the output pulley 322 is the same as the height of the synchronous pulley 326.

[0039] The desiccant boxes 206 are symmetrically arranged on the inner surface of the monitoring device housing 203. The breathable mesh plate 207 is provided with a mesh hole structure.

[0040] The connecting plates 104 are uniformly distributed on the fixing ring 103. After the sliding baffles 330 are butted, the overall shape and size are the same as the shape and size on both sides of the monitoring device housing 203.

[0041] During specific use, the main support sleeve 101 is fixedly installed at a designated outdoor monitoring position through the fastening bolt 113. The height of the monitoring device housing 203 is adjusted according to actual needs. The staff manually rotates and removes the locking nut 110 provided on the bump 109. After removing the locking nut 110, the sliding bracket 107 can be adjusted up and down. While adjusting the position of the sliding bracket 107, the position of the lifting rod 102 is adjusted upward. The higher the height of the monitoring device housing 203, the greater the inclination angle of the rotating rod 105. After the height adjustment of the monitoring device housing 203 is completed, the position of the sliding bracket 107 is fixed using the locking nut 110. Subsequently, the position of the positioning plate 112 is fixed using the fastening bolt 113. At this time, the position of the monitoring device housing 203 is fixed.

[0042] When the wind blows from the outside onto the wind vane 204, the wind vane 204 drives the monitoring device housing 203 to rotate under the action of the wind, so that the air inlet of the monitoring device housing 203 can face the wind direction, ensuring that air can flow into the monitoring device housing 203 normally to the greatest extent. When the wind blows the wind receiving plate 301, the wind receiving plate 301 rotates under the action of the wind. At this time, the movable top block 305 will slide under the action of centrifugal force. When the wind force is small, the rotation speed of the wind receiving plate 301 is slow, and the centrifugal force received by the movable top block 305 is small. Therefore, the displacement of the movable top block 305 is small, and the movable top block 305 cannot drive the sliding push rod 307 to displace, and the distance between the sliding baffles 330 remains unchanged.

[0043] When the external wind force is relatively large, the rotation speed of the wind receiving plate 301 increases, the centrifugal force received by the movable top block 305 increases and the displacement of the sliding push rod 307 increases. The movable top block 305 pushes the sliding push rod 307 to displace. While the sliding push rod 307 displaces, it drives the driven gear 310 to rotate through the driving rack 309. The driven gear 310 drives the transmission shaft 311 to rotate. The transmission shaft 311 drives the synchronous gear 312 to rotate. The synchronous gear 312 rotates to drive the follower gear 314 to rotate. The follower gear 314 rotates to drive the positioning rotating shaft one 315 to rotate, and the rotation direction of the positioning rotating shaft one 315 is opposite to that of the transmission shaft 311. The positioning rotating shaft one 315 drives the driving pulley one 316 to rotate. The driving pulley one 316 drives the follower pulley 319 to rotate through the transmission belt 320. The follower pulley 319 drives the positioning rotating shaft two 317 to rotate, so that the positioning rotating shaft two 317 drives the driving gear one 318 to rotate. At the same time, the transmission shaft 311 rotates to drive the driving pulley 313 to rotate. The driving pulley 313 drives the connecting pulley 323 to rotate through the synchronous belt 324. The connecting pulley 323 rotates to drive the positioning rotating shaft three 321 to rotate, and the rotation direction of the positioning rotating shaft three 321 is the same as that of the transmission shaft 311. The positioning rotating shaft three 321 rotates to drive the output pulley 322 to rotate. The output pulley 322 rotates to drive the synchronous pulley 326 to rotate through the connecting belt 327. The synchronous pulley 326 drives the positioning rotating shaft four 325 to rotate. The positioning rotating shaft four 325 drives the connecting belt 327 to rotate. The rotation direction of the connecting belt 327 is different from that of the driving gear one 318. The connecting belt 327 and the driving gear one 318 rotate to drive the sliding rack 329 to displace in the reverse direction, thereby driving the sliding baffle 330 to slide, increasing the distance between the sliding baffles 330, and reducing the wind speed of the air entering the inside of the monitoring device housing 203.

[0044] A ventilation filter screen 331 is provided at the front end of the monitoring device housing 203. When the air enters the monitoring device housing 203, it will pass through the filtration of the ventilation filter screen 331. At the same time, a desiccant for drying the air is placed in the desiccant box 206 in advance. When the air moves inside the monitoring device housing 203, it will contact the desiccant, thereby reducing the humidity of the air inside the monitoring device housing 203. Finally, the air is discharged from the monitoring device housing 203 after being detected by the particulate matter detector 205. The above is the overall working process of the present invention. Just repeat this step the next time it is used. The actual operation process is very simple and easy.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.
