[0035] This application makes improvements and innovations and provides the following embodiments.

[0036] In some embodiments, please refer to Figures 1 to 8 , a device for collecting atmospheric wet and dry deposition is provided, including: A box body 1, with a first opening 11 and a second opening 12 formed at the top of the box body 1; A sealing structure 2, the sealing structure 2 includes a rotating frame 21, three cover plates 22, and a first motor 23; the rotating frame 21 is rotatably connected to the top of the box body 1; the three cover plates 22 are arranged at intervals around the rotating shaft of the rotating frame 21, and each cover plate 22 is fixedly connected to the rotating frame 21; each cover plate 22 can cover the first opening 11 and the second opening 12; the first motor 23 is fixedly installed inside the box body 1, and the output end of the first motor 23 is in transmission connection with the rotating frame 21; The first collection mechanism 3 is installed inside the box body 1 and communicates with the first opening 11; The second collection mechanism 4 is installed inside the box body 1 and communicates with the second opening 12.

[0037] Among them, the first collection mechanism 3 is used to collect atmospheric dry deposition, and the second collection mechanism 4 is used to collect atmospheric wet deposition; when the first motor 23 can drive the rotating frame 21 to rotate to the first position, two cover plates 22 simultaneously cover the first opening 11 and the second opening 12 correspondingly, and when the first motor 23 can drive the rotating frame 21 to rotate to the second position, only one cover plate 22 covers the first opening 11.

[0038] A battery 5 is provided inside the box body 1, and a solar panel is provided outside the box body 1 to charge the battery 5. The battery 5 is electrically connected to the processor 6 to supply power to the processor 6 and various electrical devices electrically connected to the processor 6.

[0039] By driving the rotating frame 21 through the first motor 23, the rotating frame 21 drives the three cover plates 22 to rotate accordingly. When the first motor 23 can drive the rotating frame 21 to rotate to the first position, two cover plates 22 simultaneously cover the first opening 11 and the second opening 12 correspondingly, and when the first motor 23 can drive the rotating frame 21 to rotate to the second position, only one cover plate 22 covers the first opening 11. Since this application does not require manual covering of the cover plate 22, compared with the situation where manual covering of the cover plate 22 is required, it can reduce the labor intensity of the staff; it is also convenient for the collection work to be carried out.

[0040] Moreover, since the first collection mechanism 3 and the second collection mechanism 4 are integrated inside the box body 1, it is convenient for handling and collection. At the same time, it is also convenient for the cover plate 22 to cover the first opening 11 and the second opening 12, avoiding the situation where manual covering of the cover plate 22 is required.

[0041] In some embodiments, the first collection mechanism 3 includes: a filter cylinder 31, an air pump 32, and a collection bucket 33; one end of the filter cylinder 31 communicates with the first opening 11, and the other end communicates with the air inlet of the air pump 32; a filter screen 34 is fixedly connected inside the filter cylinder 31, and a cleaning member 35 for cleaning impurities on the filter screen 34 is arranged on the filter screen 34; the cleaning member 35 communicates with the collection bucket 33; the collection bucket 33 is detachably connected to the bottom of the box body 1. After the air passes through the filter cylinder 31 and the filter screen 34, the impurities remain on the filter screen 34. The impurities are cleaned by the cleaning member 35 and then enter the collection bucket 33 for collection. At the same time, due to the cleaning work of the cleaning member 35, the filtering function of the filter screen 34 can be guaranteed, and the filtering efficiency can be improved. This design is ingenious and reasonable.

[0042] Specifically, the bottom of the box body 1 is provided with mounting holes, and the outer part of the collection bucket 33 is in threaded fit with the inner wall of the through hole. The threaded fit between the collection bucket 33 and the through hole facilitates the installation and disassembly of the collection bucket 33, so as to facilitate the staff to take out the collected samples in the collection bucket 33.

[0043] In some embodiments, it further includes a support column 13, and the support column 13 is fixedly connected to the bottom of the box body 1. The provision of the support column 13 facilitates the staff to take out or install the collection bucket 33 from the bottom of the box body 1.

[0044] In some embodiments, the cleaning member 35 includes a sliding cover 351, a lead screw 352, a cleaning roller 353, a connecting pipe 354, and a second motor 355; the sliding cover 351 is buckled on the filtering end face of the filter net 34, and the sliding cover 351 is in threaded fit with the lead screw 352; the lead screw 352 is rotatably connected to the inner wall of the filter cylinder 31; the extending direction of the lead screw 352 is parallel to the plane where the filter net 34 is located; the cleaning roller 353 is located inside the sliding cover 351 and is rotatably connected to the sliding cover 351, and the cleaning roller 353 is in close contact with the filter net 34; one end of the connecting pipe 354 is communicated with the inside of the sliding cover 351, and the other end is communicated with the collection bucket 33 through an air extraction pump 32; the second motor 355 is fixedly connected inside the box body 1, and the output end of the second motor 355 is in transmission connection with the lead screw 352 through a sprocket. The area covered by the sliding groove forms a negative pressure area after being connected and pumped, so that the impurities in this area are sucked into the connecting pipe 354 and finally enter the collection bucket 33; the sliding cover 351 moves along the extending direction of the lead screw 352 under the drive of the lead screw 352, realizing the movement of the sliding cover 351 on the filter net 34, and further realizing the comprehensive cleaning of the filter net 34. As the sliding cover 351 moves, the cleaning roller 353 rolls on the filter net 34, which can loosen the impurities on the filter net 34 and improve the cleaning effect.

[0045] Specifically, the number of the lead screws 352 is two arranged at intervals. The two lead screws 352 can offset the torque of the sliding cover 351 rotating along the axial direction of the lead screw 352. The filter cylinder 31 is of a square cylindrical structure. The square cylinder facilitates the layout of the filter net 34 and the sliding cover 351.

[0046] In some embodiments, one end of the cleaning roller 353 is in transmission connection with a roller 356 through a belt; the roller 356 is rotatably connected to the sliding cover 351 and is in close contact with the lead screw 352. As the roller 356 rotates, the cleaning roller 353 is driven to rotate. The rotation direction of the cleaning roller 353 is not meshed with the moving direction of the cleaning roller 353. Therefore, the cleaning effect of the cleaning roller 353 on the impurities is increased and the cleaning efficiency is improved.

[0047] Specifically, the number of the cleaning rollers 353 is multiple, and each adjacent cleaning roller 353 is in transmission connection through a belt. The multiple cleaning rollers 353 can improve the cleaning effect.

[0048] In some embodiments, the number of the filter meshes 34 is multiple, and the multiple filter meshes 34 are arranged at intervals along the extending direction of the filter cylinder 31; the number of the cleaning members 35 corresponds to the number of the filter meshes 34 one by one. Specifically, along the airflow direction of the filter cylinder 31, the mesh sizes of the filter meshes 34 gradually decrease. The multiple filter meshes 34 can achieve step-by-step filtration, improving the filtration effect.

[0049] Specifically, each connecting pipe 354 communicates with a main pipe 357, and the main pipe 357 communicates with the air inlet of the air extraction pump 32, avoiding the redundant design of directly connecting each connecting pipe with the air inlet of the air extraction pump 32. The adjacent two lead screws 352 are driven by a chain wheel. One of the lead screws 352 is driven by a chain wheel to be connected with the output end of the second motor 355.

[0050] In some embodiments, a collection net 331 is arranged in the collection bucket 33; the mesh size of the collection net 331 is smaller than that of the filter mesh 34; an air outlet hole 332 is formed in the bottom of the collection bucket 33. All impurities are enriched on the collection net 331, and the staff only needs to handle the impurities on the collection net 331. The size of the collection net 331 is smaller than that of the filter mesh 34, so the processing time can be reduced and the work load can be lowered. Moreover, after collecting enough samples, the collection bucket 33 can be removed, the valve body 62 connected to the collection cylinder can be opened, and the other valve body 62 can be closed. At this time, the cleaning of the filter mesh 34 can be simply realized.

[0051] Specifically, the mesh size of the collection net 331 is smaller than or the same as that of the filter mesh 34 with the smallest mesh size. It can ensure that the impurities collected in the collection net 331 are impurities of all sizes in the filter mesh 34.

[0052] Specifically, a check valve 333 is arranged in the air outlet hole 332. The check valve 333 includes a tension spring 3331 and two plate bodies 3332; one end of the tension spring 3331 is fixedly connected to the inner wall of the air outlet hole 332, and the other end is fixedly connected to the plate body 3332; both of the two plate bodies 3332 are hinged to the edge of the air outlet hole 332; the tension spring 3331 is always in a tension state, pressing the two plate bodies 3332 against each other. When the air pressure in the collection bucket 33 is large enough to overcome the tension of the tension spring 3331, the two plate bodies 3332 are separated. It can prevent external moisture from entering the collection bucket 33 and affecting the impurities in the collection bucket 33, ensuring the stability of the impurities.

[0053] Specifically, a heating wire 8 is arranged in the collection bucket 33. It can reduce the influence of water vapor on the impurities.

[0054] In some embodiments, the second collection mechanism 4 includes: a connecting cylinder 41 and a collection box 42; one end of the connecting cylinder 41 communicates with the second opening 12, and the other end communicates with the inlet of the collection box 42; an electromagnetic valve 43 for opening or closing the inlet is provided on the inlet of the collection box 42. Setting the electromagnetic valve 43 can reduce the evaporation of water vapor in the collection box 42 and ensure the accuracy of the sample.

[0055] Specifically, the electromagnetic valve 43 is slidably clamped and connected to one end of the connecting cylinder 41, and the electromagnetic valve 43 is fixedly connected to the inlet of the collection box 42. An installation opening for the collection box 42 to enter and exit is provided on the box body 1, and a door panel is hinged and covered on the edge of the installation opening. Setting the installation opening can facilitate the replacement of different collection boxes 42 to obtain more collected samples.

[0056] Specifically, an exhaust pipe 321 is connected to the air outlet position of the air extraction pump 32. One end of the exhaust pipe 321 communicates with the air outlet position of the air extraction pump 32, and the other end is provided with a valve body 62. The exhaust pipe 321 is connected to the collection bucket 33 through a collection pipe 322. The collection pipe 322 is in threaded fit with the inlet of the collection bucket 33. By rotating the collection bucket 33, tightening or separation from the collection pipe 322 can be achieved. It is convenient to connect and take and place the collection bucket 33. A valve body 62 is provided on the collection pipe 322; the exhaust pipe 321 is connected to a pipe body 323. The air outlet of the pipe body 323 is located inside the connecting cylinder 41, and the air outlet direction of the air outlet of the pipe body 323 is downward along the inner wall of the connecting cylinder 41, which can be used to blow the water droplets on the inner wall of the connecting cylinder 41 into the collection box 42. A valve body 62 is provided on the pipe body 323 to control the gas flow or blockage inside the pipe body 323, realizing the function of precisely purging water droplets.

[0057] Specifically, the air outlet of the pipe body 323 is connected to a scavenging ring 324. The scavenging ring 324 has a plurality of exhaust outlets distributed at intervals. The scavenging ring 324 is sleeved and fixed outside the connecting cylinder 41. The exhaust outlets communicate with the inside of the connecting cylinder 41, and the air outlet direction of each exhaust outlet is downward along the inner wall of the connecting cylinder 41. Setting a plurality of exhaust outlets can blow the water droplets on the inner wall of the connecting cylinder 41 more evenly and clean the water droplets on the inner wall of the connecting cylinder 41 more thoroughly.

[0058] When it is necessary to blow water droplets, open the valve body 62 inside the pipe body 323 and close the valve bodies 62 of the exhaust pipe 321 and the collection pipe 322. When it is necessary to collect the dry deposition collected sample, open the valve body 62 of the collection pipe 322 and close the other two valve bodies 62 to realize the function of collecting impurities. When it is necessary to collect a sample, open the valve body 62 of the exhaust pipe 321 and close the other two valve bodies 62 to realize the filtering function.

[0059] All three valve bodies 62 are electrically connected to the processor 6 to realize the processor 6 controlling the closing of the valve bodies 62, improving the automation degree of the device.

[0060] In some embodiments, a refrigerator 7 is fixedly connected to the outside of the collection box 42. The setting of the refrigerator 7 can reduce the evaporation of water vapor.

[0061] Specifically, a heat-insulating layer 44 is provided on the outside of the collection box 42, and the refrigerating surface of the refrigerator 7 passes through the heat-insulating layer 44 and fits against the outer wall of the collection box 42. A hydrophobic coating is applied to the inner wall of the connecting cylinder 41. The refrigerator 7 is a semiconductor refrigerator 7. The setting of the heat-insulating layer 44 can reduce the evaporation of water vapor. The refrigerator can keep the temperature of the collection box 42 at a constant 4°C, effectively preventing the degradation of the collected samples by microorganisms and improving the accuracy of the samples.

[0062] In some embodiments, it further includes a processor 6 installed in the box body 1, and a humidity sensor 61 is further provided outside the box body 1; both the first motor 23 and the humidity sensor 61 are electrically connected to the processor 6. The setting of the humidity sensor 61 enables the controller to control the rotation of the first motor 23 during precipitation, thereby controlling the cover plate 22 to cover the first opening 11 and simultaneously opening the second opening 12 for collecting wet deposition samples.

[0063] Specifically, the second motor 355, the air extraction pump 32, the valve body 62, the solenoid valve 43, and the refrigerator 7 are all electrically connected to the processor 6. Through the controller, the automation degree of the collection device can be correspondingly controlled.

[0064] A liquid level sensor 63 is arranged in the collection box 42, a temperature sensor 64 and a humidity sensor 61 are arranged on the box body 1, and the liquid level sensor 63, the temperature sensor 64, and the humidity sensor 61 are all electrically connected to the controller. Through the feedback signal of the humidity sensor 61, the processor 6 judges whether there is precipitation in the environment, and then controls the rotation of the first motor 23, and finally realizes the position where the cover plate 22 is closed, improving the automation degree of the device. The controller uses an STM32 chip, and the processor 6 has strong capabilities.

[0065] An infrared induction bird repeller is further arranged on the top of the box body 1. After detecting the approach of birds or other animals, the infrared induction bird repeller will automatically emit an audible and visual alarm signal to drive the animals away, reducing the situation where the box body 1 is damaged due to animals touching it.

[0066] Insect-proof nets are installed on both the first opening 11 and the second opening 12, which can prevent insects from falling into the filter screen 34 or the collection box 42 and affecting the test results of the samples.
