Description

Technical Field

[0001] At least one embodiment of the present disclosure relates to the technical field of air monitoring, and more specifically, to a pollen monitoring device. Background Art

[0002] Plants in the flowering period will produce pollen. The diameter of pollen grains is 15 to 30 μm. They are large in quantity and light in weight. They are easily attached to aerosols and spread through the air. They are generally called airborne pollen. Pollen monitoring devices are used to collect and analyze pollen in the air. Pollen index forecasts are then used to prompt relevant meteorological departments to issue relevant warnings and take measures to reduce pollen floating. People with pollen allergies can also be guided to reduce activities in areas with high pollen indexes to alleviate allergic symptoms. Since the pollen monitoring device is set up outdoors, on the one hand, mosquitoes, dust or catkins often block the sampling port, which in turn hinders the collection of pollen in the air through the sampling port, affecting the accuracy of airborne pollen monitoring. On the other hand, the complex outdoor environment will also block the sampling port, resulting in inaccurate collected data and reducing the accuracy of airborne pollen classification monitoring data.

[0003] In the related art, a cleaning brush is often provided on the filter, and the cleaning brush is moved circumferentially or axially along the sampling tube of the pollen monitoring device to clean the debris attached to the filter. However, since the cleaning brush only moves in one direction relative to the filter, the filter cannot be completely cleaned.

[0083] In the related art, the cleaning brush only moves in a single direction along the sampling tube to brush away debris attached to the filter. However, due to the structure of the filter and the complex movement path of the debris on the filter after being swept away, brushing away the debris on the filter in a single direction cannot completely remove the debris attached to the filter, resulting in low cleaning efficiency. The debris remaining on the filter will also affect the accuracy of pollen monitoring.

[0084] In view of this, an embodiment provided in the present disclosure provides a pollen monitoring device.

[0085] Figure 1 is a perspective view of a pollen monitoring device according to an illustrative embodiment of the present disclosure; Figure 2 is a partial cross-sectional view of a pollen monitoring device according to an exemplary embodiment of the present disclosure; Figure 4 is based on Figure 2 A partial enlarged view of point A of the exemplary embodiment shown.

[0086] The pollen monitoring device provided by the present disclosure is as follows: Figure 1 , Figure 2 and Figure 4As shown, it includes a body 1, a sampling mechanism 2 and a cleaning mechanism 3. The sampling mechanism 2 includes a sampling tube 21 and a filter 22. The sampling tube 21 is inserted into the body 1, and a sampling port is provided on the side of the first end of the sampling tube 21 away from the body 1. The filter 22 is arranged at the first end and covers the sampling port. The cleaning mechanism 3 includes a drum 31, a plurality of brushes 32, a first driving machine 33, and a transmission assembly. The drum 31 is rotatably arranged concentrically with the sampling tube 21. A plurality of brushes 32 are arranged in an array on the inner side of the drum 31 close to the sampling tube 21. The brush surface of the brush 32 and the outer surface of the filter 22 roughly coincide in the orthographic projection perpendicular to the extension direction of the axis of the sampling tube 21. The first driving machine 33. The transmission assembly is connected to the first driving machine 33 and cooperates with the gears of the drum 31 and the sampling tube 21; wherein, the transmission assembly, driven by the first driving machine 33, drives the drum 31 to rotate along the circumference of the sampling tube 21 and to reciprocate along the axial direction of the sampling tube 21.

[0087] According to the above-mentioned setting method, the rotating drum 31 rotates along the axial direction of the sampling tube 21 under the action of the transmission component, and the brush 32 can brush away the debris attached to the filter screen 22 along the lateral direction of the filter screen 22 as the rotating drum 31 moves. In addition, the brush 32 can also reciprocate up and down with the rotating drum 31, and can continuously carry the debris attached to the filter screen 22 downward away from the filter screen 22, and can brush away the debris in the longitudinal direction of the filter screen 22, thereby improving the cleaning efficiency and ensuring the removal of debris as much as possible, ensuring the efficiency of pollen collection and the accuracy of monitoring.

[0088] According to an embodiment of the present disclosure, a rain cover 23 is further provided at the first end of the sampling tube 21, and the rain cover 23 can roughly cover the sampling port to prevent rain from affecting pollen collection and monitoring.

[0089] According to an embodiment of the present disclosure, the sampling tube 21 is connected to an air suction device, through which the air around the pollen monitoring device can be sucked to monitor the airborne pollen in the air.

[0090] According to an embodiment of the present disclosure, the first driving machine 33 may be a hand-cranked driving machine or an electric motor.

[0091] In an illustrative embodiment, Figure 4 As shown, the cleaning mechanism 3 further includes a support frame 34, which is slidably mounted on the sampling tube 21. The support frame 34 is also configured with a support seat (not shown in the figure), which is suitable for assembling the rotating drum 31. The support seat and the rotating drum 31 are clearance-matched to allow the rotating drum 31 to rotate along the circumference of the sampling tube 21.

[0092] According to the embodiments of the present disclosure, the support seat and the rotating drum 31 can be matched through the clearance of the sleeve, and can also be rotatably connected through the bearing. The outer wall of the support seat is embedded with the inner ring of the bearing, and the inner wall of the rotating drum 31 is embedded with the outer ring of the bearing, so that the rotating drum 31 can move along the axial direction of the sampling tube 21 when the support frame 34 moves along the axial direction of the sampling tube 21.

[0093] In an illustrative embodiment, Figure 4 As shown, at least a portion of the non-output end of the first driving motor 33 is fixedly connected to the support frame 34; at least a portion of the transmission assembly is rotatably disposed on the support frame 34; wherein, driven by the first driving motor 33, the support frame 34 responds to the transmission of the transmission assembly and reciprocates along the axial direction of the sampling tube 21, thereby driving the rotating drum 31, the first driving motor 33 and the transmission assembly to reciprocate along the axial direction of the sampling tube 21.

[0094] In an illustrative embodiment, Figure 4 As shown, the side wall of the sampling tube 21 is fixedly connected with a first rack 211, and the first rack 211 is arranged along the axial direction of the sampling tube 21. A gear ring 311 is arranged on the outer side wall of the rotating drum 31. The transmission assembly includes a driving shaft 35 and a first driven shaft 36. The driving shaft 35 is connected to the output end of the first driving machine 33, and is sleeved with a driving gear 351, and the driving gear 351 is meshed with the gear ring 311 to drive the rotating drum 31 to rotate. The first driven shaft 36 is arranged perpendicular to the driving shaft 35, and is matched with the driving shaft 35 through gears. The output end of the first driven shaft 36 is sleeved with an output gear 361, and the output gear 361 is meshed with the first rack 211. The support end of the first driven shaft 36 away from the output end is rotatably arranged on the support frame 34. The first driven shaft 36 reciprocates alternately in the counterclockwise and clockwise directions under the drive of the driving shaft 35 , and the output gear 361 reciprocates axially relative to the sampling tube 21 in response to the reciprocating movement of the first driven shaft 36 , thereby driving the drum 31 to reciprocate axially in the sampling tube 21 .

[0095] According to an embodiment of the present disclosure, a first groove 341 is further formed at the bottom of the support frame 34, which is aligned with the first rack 211, and the width of the first groove 341 is equal to or greater than the width of the first rack 211, so as to allow the first rack 211 to pass through.

[0096] In an illustrative embodiment, Figure 4 As shown, the output end of the driving shaft 35 that cooperates with the first driven shaft 36 is sleeved with a first half-bevel gear. The first driven shaft 36 is sleeved with two first bevel gears 362 that are arranged opposite to each other, and the two first bevel gears 362 are configured to mesh with the first half-bevel gears respectively. The tooth surface of the first half-bevel gear meshes with the tooth surface of the two first bevel gears 362 alternately to drive the first driven shaft 36 to reciprocate in clockwise and counterclockwise directions.

[0097] According to the embodiment of the present disclosure, when the pollen monitoring device is in a non-working state, the first driving machine 33 is started, the first driving machine 33 drives the driving shaft 35 to rotate, and the driving gear 351 on the driving shaft 35 drives the rotating drum 31 to rotate by cooperating with the gear ring 311, so that the brush 32 brushes away the mosquitoes, dust, catkins and other debris attached to the filter 22 in the horizontal direction. In addition, because the first half-face bevel gear alternately cooperates with the tooth surface of the two bevel gears, the first driven shaft 36 reciprocates in the clockwise and counterclockwise directions, and the output gear 361 sleeved on the output end of the first driven shaft 36 reciprocates upward or downward along the axial direction of the first rack 211, thereby driving the support frame 34 and the rotating drum 31 to reciprocate up and down along the axial direction of the sampling tube 21, so that the brush 32 brushes away the debris attached to the filter 22 in the longitudinal direction, and can also enable the brush 32 to take away a part of the debris when leaving the filter 22, so as to prevent the debris from remaining on the filter 22.

[0098] In an illustrative embodiment, Figure 4 As shown, the cleaning mechanism 3 also includes a cleaning fan, which includes a collar 37 and a plurality of blades 38. The collar 37 is slidably mounted on the sampling tube 21. The plurality of blades 38 are arranged in an array in the drum 31, and the two ends of each blade 38 are respectively connected to the collar 37 and the drum 31; the windward surface of each blade 38 is arranged away from the main body 1.

[0099] According to the above-mentioned arrangement, when the drum 31 rotates under the drive of the first driving machine 33 , the cleaning fan will also rotate along with the rotation of the drum 31 to blow away the sundries and the like attached to the filter screen 22 .

[0100] Figure 5 is based on Figure 2 A partial enlarged view of point B of the exemplary embodiment shown.

[0101] In an illustrative embodiment, Figure 5 As shown, the pollen monitoring device further includes a lifting mechanism 4, which includes a base 41, a top plate 42, a second driving machine 43, and a lifting frame assembly. The top plate 42 is connected to the body 1. The second driving machine 43 is fixed to the base 41 by installing a sink 411. The lifting frame assembly is arranged on the base 41 and cooperates with the second driving machine 43 through gears; the lifting frame assembly is connected to the top plate 42; the lifting frame assembly is configured to lift or lower the top plate 42 under the drive of the second driving machine 43 to lift or lower the body 1.

[0102] According to the above-mentioned setting method, when the pollen monitoring device is located in a position where there is a relatively serious obstruction to the sampling tube 21, for example, when a tree branch blocks the sampling port, pollen may not be collected effectively, reducing the accuracy of pollen monitoring. The lifting frame assembly can be driven by the second driving machine 43 to lift the top plate 42 to increase the height of the sampling tube 21, so that the sampling tube 21 can be higher than the height of the tree branches, etc., so that airborne pollen can be effectively collected and monitored.

[0103] According to an embodiment of the present disclosure, a limiting block 421 is further provided on the top plate 42 , and when the top plate 42 is raised, the inner wall of the limiting block 421 fits with the outer wall of the body 1 .

[0104] According to an embodiment of the present disclosure, a self-locking universal wheel 413 is also installed at the bottom of the base 41 close to the ground.

[0105] In an illustrative embodiment, Figure 5 As shown, the lifting frame assembly includes a first transmission shaft 44, two sliders 45 and four lifting rods 46. The first transmission shaft 44 is arranged perpendicularly to the output end of the second driving machine 43 and cooperates with the second driving machine 43 through gears. The two sliders 45 are perpendicular to the first transmission shaft 44, arranged at both ends of the first transmission shaft 44, and are configured to move toward or away from each other as the first transmission shaft 44 rotates. The four lifting rods 46 are arranged at both ends of the slider 45, and the two ends of each lifting rod 46 are rotatably connected to the slider 45 and the top plate 42 respectively. Each lifting rod 46 is configured to lift the top plate 42 in response to the movement of the slider 45 toward each other, and to lower the top plate 42 in response to the movement of the slider 45 away from each other.

[0106] In an illustrative embodiment, Figure 5 As shown, the output end of the second driving machine 43 is sleeved with a second bevel gear 431, and the first transmission shaft 44 is sleeved with a third bevel gear 441, and the third bevel gear 441 is meshed with the second bevel gear 431. Two side plates 412 are symmetrically arranged on the base 41, and the side plates 412 are connected to the first transmission shaft 44 through threads, and the slider 45 is also connected to the inner side of the side plate 412 through threads. When the first transmission shaft 44 rotates, the slider 45 moves toward or away from each other through the action of the threads to drive the lifting rod 46 to rise and fall, so that the sampling tube 21 can be at a height that can normally collect pollen.

[0107] According to an embodiment of the present disclosure, the first transmission shaft 44 is a stud bolt.

[0108] Figure 3 is based on Figure 2 A partial cross-sectional view of the pollen monitoring device of the exemplary embodiment shown in another perspective; Figure 6 is based on Figure 3A partial enlarged view of point C of the exemplary embodiment shown.

[0109] In an illustrative embodiment, Figure 3 and Figure 6 As shown, the base 41 is provided with a matching gear 414 and a second groove 415, and the top plate 42 is also provided with a second rack 422 and a third groove 423.

Among them, the matching gear 414 is meshed with the second rack 422 and the third rack 471 respectively.

[0110] According to the above-mentioned setting method, when the top plate 42 moves upward, the second rack 422 moves upward with the top plate 42 and drives the matching gear 414 to rotate, and the matching gear 414 drives the third rack 471 to move downward, thereby driving the stabilizing bottom plate 47 to move downward until the stabilizing bottom plate 47 is tightly fitted to the ground to stabilize the raised main body 1.

[0111] Figure 7 is based on Figure 2 A partial enlarged view of D of the exemplary embodiment shown.

[0112] In an illustrative embodiment, Figure 7 As shown, the pollen monitoring device also includes a rain shielding mechanism 5. A temperature regulating device is arranged in the body 1, and an exhaust port is opened on the side wall of the body 1 near the temperature regulating device. The rain shielding mechanism 5 is suitable for shielding the temperature regulating device from rain when there is precipitation, and includes a second transmission shaft 51, a plurality of second driven shafts 52, a plurality of rain shields 53, a driving rod 54, and a synchronous belt 55. The two ends of the second transmission shaft 51 are rotatably mounted on the wall surfaces on both sides of the exhaust port. The plurality of second driven shafts 52 are parallel to the second transmission shaft 51 and are arranged at intervals along the height direction of the body 1, and the two ends of the second driven shaft 52 are rotatably mounted on the wall surfaces on both sides of the exhaust port. The plurality of rain shields 53 are fixedly connected to the second transmission shaft 51 and the second driven shaft 52, and are configured to rotate with the second transmission shaft 51 and the second driven shaft 52. The driving rod 54 is fixedly connected to the body 1, and cooperates with the second transmission shaft 51 through gears to drive the second transmission shaft 51 to rotate. The synchronous belt 55 is arranged at the driven end of the second transmission shaft 51 away from the driving rod 54, and cooperates with each second driven shaft 52. The driving rod 54 drives the second transmission shaft to rotate, so as to drive the synchronous belt 55 to move, and then drives the second driven shaft 52 to rotate, so as to rotate the rain shield 53.

[0113] According to the above-mentioned setting, since precipitation or external debris such as leaves may enter the temperature regulating device through the exhaust port, which may affect the normal operation of the temperature regulating device, it is necessary to adjust the angle of the rain shield 53. When the angle of the rain shield 53 needs to be adjusted, the driving rod 54 is started to drive the second transmission shaft 51 to rotate, and the second transmission shaft 51 drives the second driven shaft 52 to rotate through the synchronous belt 55, so that the angle of the rain shield 53 can be adjusted to ensure the normal operation of the temperature regulating device, and further ensure that the parts related to pollen collection and analysis in the body 1 can work normally.

[0114] According to an embodiment of the present disclosure, the driving rod 54 is an electric telescopic rod.

[0115] According to an embodiment of the present disclosure, the driving rod 54 is connected to a fourth rack 541 , and the second transmission shaft sleeve is provided with a transmission gear 511 . The driving rod 54 is meshed with the transmission gear 511 through the fourth rack 541 to drive the second transmission shaft to rotate.

[0116] According to the embodiment of the present disclosure, the second transmission shaft 51 and each second driven shaft 52 are sleeved with a synchronous gear 56 , and the synchronous belt 55 is also correspondingly provided with a toothed structure to mesh with the synchronous gear 56 .

[0117] Figure 8 is a principle block diagram of a pollen monitoring device according to an illustrative embodiment of the present disclosure.

[0118] In an illustrative embodiment, Figure 8 As shown, the body 1 also includes a storage module 11, a microscope module 12, a transportation module 13 and a control module 14. The storage module 11 is connected to the sampling tube 21 and is suitable for storing pollen samples collected by the sampling tube 21. The microscope module 12 is suitable for microscopic photography and analysis of pollen samples. The transportation module 13 is suitable for transporting pollen samples from the storage module 11 to the microscope module. The control module 14 is electrically connected to the storage module 11, the microscope module 12 and the transportation module 13 to control the storage module 11, the microscope module 12 and the transportation module 13 to store, transport and analyze pollen samples.

[0119] Based on the above technical solution, the pollen monitoring device disclosed in the present invention has one or part of the following beneficial effects:

[0120] 1. Through the cooperation between the transmission assembly, the support frame, the rotating drum and the first rack, the brush can move along the circumference of the sampling tube and reciprocate along the axial direction of the sampling tube, so as to clean the debris attached to the filter from multiple directions, thereby improving the efficiency of the filter cleaning and ensuring the normal operation of subsequent air extraction and collection of the pollen monitoring device.

[0121] 2. The lifting mechanism can quickly move the main body to a high place and fix it, thereby ensuring the normal use of the main body in locations with more serious obstruction, thereby effectively ensuring the accuracy of the collected data and further effectively improving the accuracy of airborne pollen monitoring data.

[0122] 3. Through the setting and use of the rain shield mechanism, all rain shields can be driven to rotate synchronously, so that the inclination angle of the rain shield can be conveniently adjusted, thereby ensuring the normal use of the temperature control equipment, and can effectively intercept external rainwater and impurities such as leaves, thereby effectively preventing rainwater and impurities such as leaves from entering the temperature control equipment and accumulating, thereby ensuring the normal use of the temperature control equipment and thus ensuring the normal monitoring of pollen in the body.
