The migration, transformation, fate and ecotoxicological effects of microplastics in the environment have attracted much attention. The latest research has found that microplastics also exist in the atmosphere and glaciers in remote areas, and the trend of global microplastic pollution is obvious. Atmospheric transport is an important link in the global transport and circulation of microplastics. At present, the research on atmospheric microplastics mostly focuses on urban areas.

The outer sides of the two rotating rods 11 are wrapped with a transmission belt 12, and the two rotating rods 11 support the transmission belt 12.

[0043] The collection component 5 further includes a fixed horizontal plate 14, a fixed rod 15, a driving plate 16, and a guiding block 17. The top of the fixed vertical plate 10 close to the push handle 3 is fixedly connected with a fixed horizontal plate 14. The bottom of the fixed horizontal plate 14 away from the fixed vertical plate 10 is fixedly connected with a fixed rod 15, and the bottom of the fixed rod 15 is fixedly connected to the top of the moving base 1. The outer side of the transmission belt 12 close to the push handle 3 is fixedly connected with a driving plate 16. Both sides of the driving plate 16 are fixedly connected with guiding blocks 17, and the guiding blocks 17 are in clearance fit with the fixed rods 15.

[0044] The collection component 5 further includes a second motor 18, a rotating disk 19, an extension base 20, a third motor 21, a first threaded rod 22, and an extension plate 23. A circular movable groove is formed at the top of the driving plate 16. The center position of the circular movable groove is fixedly connected to the second motor 18.

The top of the rotating disk 19 is fixedly connected to the extension base 20. The bottom inside the extension base 20 is fixedly connected to the third motor 21. The output end at the top of the third motor 21 is fixedly connected to the first threaded rod 22. The inside of the top of the extension base 20 is in clearance fit with the extension plate 23, and the bottom of the extension plate 23 is threadedly connected to the top of the first threaded rod 22.

[0045] The collection component 5 further includes a fixed concave plate 24, a suction collection module 25, a fourth motor 26, and a shielding net 27.

The suction port of the suction collection module 25 is detachably connected to the shielding net 27.

[0046] Specifically: By turning on the first motor 13, one of the rotating rods 11 can be driven to rotate. At the same time, through the wrapping of the two rotating rods 11 around the transmission belt 12, the transmission belt 12 can be driven to rotate around the two rotating rods 11, so as to achieve the effect of adjusting the height of the driving plate 16.

[0047] While the driving plate 16 moves up and down, the guiding block 17 can be driven to move synchronously. At the same time, through the clearance fit between the guiding block 17 and the fixed rod 15, the driving plate 16 can be smoothly moved and supported.

[0048] While the driving plate 16 moves upward, the suction collection module 25 at the top can be driven to move synchronously, so that the suction collection module 25 can suck air and adsorb microplastics in the air.

[0049] Through the setting of the shielding net 27, dust impurities, microplastics, etc. in the air can be blocked during the suction process of the suction collection module 25, so as to reduce the entry and accumulation of dust impurities and microplastics into the inside of the suction collection module 25, thereby improving the service life of the suction collection module 25 and also improving the accuracy of detecting microplastics in the air.

[0050] At the same time, through the detachable connection setting of the shielding net 27, it is convenient to replace the shielding net 27, so that the accuracy of each detection can be maintained during multiple detections.

[0051] When it is necessary to detect the air at a higher position, the third motor 21 can be turned on after the driving plate 16 is moved to the highest position, and the third motor 21 can drive the first threaded rod 22 to rotate, so that the extension plate 23 threadedly connected to the first threaded rod 22 can be lifted upward inside the extension base 20, thereby further increasing the height of the air suction and collection module 25;

At the same time, by turning on the second motor 18, the rotating disk 19 can be driven to rotate on the top of the driving plate 16, so as to further adjust the angle of the air suction port of the air suction and collection module 25, so as to achieve the effect of sucking and collecting microplastics in the air at multiple angles, and further improve the accuracy of detecting microplastics in the air.

[0053] Embodiment 3:

[0054] This Embodiment 3 further discloses the specific structure of the moving component 6 on the premise of the above embodiments. By cooperating the moving component 6 with the structures in the above embodiments, the distance between the camera and the microplastics can be adjusted, so as to facilitate the observation of the microplastics, and further improve the accuracy of image recognition of the microplastics.

[0055] Further optimize the intelligent recognition device for airborne microplastic particles based on images provided in Embodiment 1 and Embodiment 2. Specifically, as Figure 7 shown, the moving component 6 includes a moving block 28, a second threaded rod 29, a guide rod 30 and a fifth motor 31. Three moving blocks 28 are fixedly connected to the bottom of the fixed cabinet 7. One end of the moving base 1 near the push handle 3 is provided with three square movable grooves, and the position of each square movable groove corresponds to that of the moving block 28.

The position of the fifth motor 31 corresponds to that of the second threaded rod 29, and the output end of the fifth motor 31 extends into the inside of the square movable groove and is fixedly connected to the second threaded rod 29.

[0056] Specifically, by turning on the second threaded rod 29, the moving block 28 threadedly connected to the second threaded rod 29 can be driven to move horizontally inside the corresponding square moving slot, so that the fixed cabinet 7 can be driven to move horizontally synchronously on the top of the moving base 1 through the fixed connection between the moving block 28 and the fixed cabinet 7, thereby the distance between the detection camera 8 and the shielding net 27 can be adjusted;

[0057] While the moving block 28 drives the fixed cabinet 7 to move, the other two moving blocks 28 will also be driven by the fixed cabinet 7 to move synchronously inside the other two square moving slots. At this time, through the clearance fit between the guide rod 30 and the moving block 28, a stable moving effect can be achieved on the overall fixed cabinet 7.

Three square movable grooves are formed at one end of the top of the moving base (1) close to the push handle (3), and the position of each square movable groove corresponds to that of the moving block (28). A second threaded rod (29) is rotatably connected to the inside of one of the square movable grooves, and the corresponding moving block (28) extends to the inside of the square movable groove and is threadedly connected to the second threaded rod (29). Guiding rods (30) are fixedly connected to the inside of the other two square movable grooves, and the other two moving blocks (28) both extend to the inside of the corresponding square movable grooves and are arranged in clearance fit with the guiding rods (30). A fifth motor (31) is fixedly connected to one end of the moving base (1) close to the push handle (3). The position of the fifth motor (31) corresponds to that of the second threaded rod (29), and the output end of the fifth motor (31) extends to the inside of the square movable groove and is fixedly connected to the second threaded rod (29).
