Description

Technical Field

[0001] This invention relates to the field of atmospheric monitoring technology, and in particular to a sampling device for atmospheric monitoring. Background Technology

[0002] Atmospheric sampling is a crucial step in obtaining gas samples for composition analysis in fields such as environmental monitoring, occupational health, and scientific research. With the diversification and increasing complexity of monitoring needs, higher requirements are placed on the flexibility, stability, adaptability, and efficiency of sampling equipment. However, current mainstream atmospheric sampling technologies and equipment still have many limitations.

[0003] Traditional sampling equipment is typically designed with a single function, focusing on the collection of specific types of pollutants. When faced with complex tasks requiring simultaneous sampling of multiple pollutants or the integration of different pretreatment accessories, multiple independent devices are often needed, along with tedious manual connection, switching, and debugging. This not only increases operational complexity and time costs, reduces sampling efficiency, but also limits application flexibility in confined spaces or scenarios requiring rapid response. Existing systems generally lack a universal platform that can efficiently and stably integrate multiple sampling accessories and consumables, and enable rapid combination and switching.

[0004] Sampling equipment typically needs to be placed directly or adjacent to the target sampling point. In environments with high-speed airflow, complex turbulence, temperature and humidity gradients, or high concentrations of aerosols, the presence of the sampling equipment itself and its operators can easily disturb the local flow field (microenvironment effect), compromising the representativeness of the sampling. The equipment sensors, pumps, and operators may also be directly exposed to harsh environments (high temperature, high humidity, corrosive gases, large particles), leading to equipment damage, data drift, or sampling failure. In particular, large particles, due to their greater inertia, are prone to impact and deposition at the sampling inlet or front-end equipment in high-speed or turbulent environments, interfering with the collection of subsequent samples and affecting the accuracy of the results. Existing technologies struggle to effectively achieve long-distance physical separation between the sampling probe and the core sampling / processing unit to avoid these adverse effects.

[0005] Microenvironmental disturbances in gaseous environments: Many important sampling scenarios are located in complex outdoor environments, such as forest canopies, remote areas, or extreme weather conditions. Traditional sampling equipment is often large in size, heavy in weight, difficult to install and fix, and has high environmental requirements. Its design prioritizes the stability of laboratories or fixed sites, while neglecting the portability in the field and the tolerance to harsh environments. This leads to huge challenges in deploying equipment in areas such as high altitudes and rugged terrain, which greatly limits the spatial coverage of sampling and the expansion of application scenarios.

[0006] The present invention aims to solve the technical problems existing in the prior art, and to this end, proposes a sampling device for atmospheric monitoring. Summary of the Invention

Detailed Implementation

[0041] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1, please refer to Figures 1-4In this embodiment of the invention, an atmospheric monitoring sampling device includes a movable mounting plate 1, with traction rings 7 symmetrically arranged at both ends of the movable mounting plate 1. A loading mounting box 2 is arranged on the upper side of the movable mounting plate 1, and two mounting partitions 21 are symmetrically arranged inside the loading mounting box 2. The device also includes: an adaptive equipment loading mechanism, located inside the loading mounting box 2 between the two mounting partitions 21, for adaptively loading and fixing various types of sampling equipment; a sampling height adjustment mechanism, located at the upper end of the loading mounting box 2, including two sets of guide mounting plates 11 symmetrically arranged at the upper end of the loading mounting box 2 and a sampling lifting plate 13 directly above them. A shear frame 39 is arranged between each of the two sets of guide mounting plates 11 and the sampling lifting plate 13, and the two sets of shear frames 39 are directly opposite each other. An anti-interference sampling module is arranged at the upper end of the sampling lifting plate 13; a combined hanging processing mechanism, including several guide mounting cylinders 23 arrayed on one side of the mounting partition 21; and movable leveling mechanisms are arranged at the four lower corners of the movable mounting plate 1.

[0043] By placing the external sampling equipment in the loading and mounting box 2 between the two mounting partitions 21, and through the adaptive adjustment of the adaptive equipment loading mechanism, various models of sampling equipment can be loaded and installed. Then, according to the sampling plan, various accessories and consumables required for sampling are prepared and combined with the guide mounting cylinder 23 for easy and stable subsequent use and movement. The device is moved to the target position and leveled using the moving leveling mechanism. The height of the sampling lifting plate 13 is then adjusted using the shear frame 39 to place the anti-interference sampling module at the predetermined sampling height. The prepared accessories are then taken out, connected, and fixed in place with the shear frame 39. This allows the sampling equipment to connect with the anti-interference sampling module through the connected accessories, enabling the sampling equipment to be started. This achieves anti-interference atmospheric sampling at a specific height, significantly improving the quality of atmospheric sampling.

[0044] Example 2, based on Example 1, please refer to... Figures 1 to 7In this embodiment of the invention, the adaptive equipment loading mechanism includes loading and mounting ports 15 and operation mounting ports 6 respectively provided on the front and rear sides of the loading and mounting box 2 between two mounting partitions 21. A plurality of grooved frames 22 are provided at the bottom of the loading and mounting box 2 between the loading and mounting ports 15 and the operation mounting ports 6. The grooved frames 22 are arranged parallel to each other at equal intervals. A plurality of elastic guide wheels 41 are rotatably arranged at equal intervals on the upper end of the grooved frames 22. A plurality of elastic compression strips 25 are provided at equal intervals on the other side of the mounting partitions 21. The elastic compression strips 25 are all arc-shaped, and the elastic compression strips 25 on the two mounting partitions 21 are arranged facing each other. Loading rotating cover plates 16 are symmetrically arranged inside the loading and mounting ports 15, and the loading rotating cover plates 16 are all installed in a split-rotation configuration to cooperate with the loading and mounting ports 15. Operation rotating cover plates 9 are symmetrically arranged inside the operation mounting ports 6, and the operation rotating cover plates 9 are all installed in a split-rotation configuration to cooperate with the operation mounting ports 6.

[0045] Each of the loading and mounting boxes 2 opposite the mounting partition 21 is provided with a storage and mounting opening 4. A storage rotating cover 5 is symmetrically arranged inside the storage and mounting opening 4. The storage rotating cover 5 is installed in a rotating manner with the storage and mounting opening 4. The loading rotating cover 16, the operation rotating cover 9 and the storage rotating cover 5 are symmetrically provided with handles 8 of integrated locks.

[0046] The sampling equipment is selected based on the sampling requirements and placed in the loading and installation box 2. Specifically, the sampling equipment is first pushed into the loading and installation box 2 through the loading and installation port 15. As the elastic guide wheel 41 rotates, the sampling equipment slides into the groove frame 22 until it contacts the opposite elastic extrusion strip 25 and is extruded and deformed until the sampling equipment is in the middle position of the elastic extrusion strip 25. At this time, the movement of the sampling equipment is restricted by the deformation and extrusion of the elastic extrusion strip 25. Only a small displacement can be achieved by the deformation compensation of the elastic extrusion strip 25, thus completing the loading of the sampling equipment and ensuring its movement and sampling stability. The operation of the rotating cover 9 can be used to operate the operation end of the sampling equipment.

[0047] The safe opening and closing of the loading rotating cover 16, operating rotating cover 9, and storing rotating cover 5 are achieved by the handle 8 of the integrated lock. The integrated lock can be achieved by rotating the handle 8 or by pressing the handle 8. Regardless of which method is used, the safety of opening and closing can be guaranteed.

[0048] Example 3, based on Example 1, please refer to... Figures 1-4 ,as well as Figure 7 , Figure 11In this embodiment of the invention, a sliding guide groove 38 is provided in half of the guide mounting plate 11. The shear frame 39 includes a plurality of shear arms 12. The ends of the shear arms 12 facing each other on the shear frame 39 are connected by a synchronous rotating shaft 32. The intersections of the shear arms 12 are connected by a loading cylinder shaft 33. The loading cylinder shafts 33 on two shear frames 39 are facing each other. A magnetic fixing block 34 is provided at the end of each loading cylinder shaft 33 facing each other. The ends of the two shear arms 12 at one end of the shear frame 39 are rotatably connected to the sampling lifting plate 13 by a synchronous rotating shaft 32. The end of one shear arm 12 at the other end of the shear frame 39 is connected to the loading cylinder shaft 32. The component is rotatably connected to the guide mounting plate 11 via a synchronous rotating shaft 32. The other end of the shear arm 12 at the other end of the shear frame 39 is movably set via a synchronous rotating shaft 32 and a sliding guide groove 38. A transmission sleeve 37 is provided in the middle section of the synchronous rotating shaft 32 between the sliding guide grooves 38. A transmission block 36 is provided in the middle position of the transmission sleeve 37. A drive winding component 17 is symmetrically arranged on the loading and mounting box 2 on both sides of the transmission block 36. The drive winding component 17 is connected to the transmission block 36 via a transmission belt 35. Two connecting mounting cylinders 10 are provided through the top of the loading and mounting box 2 between the mounting partitions 21.

[0049] The inner wall dimensions and shape of the loading cylinder shaft 33 and the guide mounting cylinder 23 are the same. A magnetic fixing block 34 is also provided at one end of the guide mounting cylinder 23 near the mounting partition 21. A combined mounting column 53 is provided in conjunction with the loading cylinder shaft 33 and the guide mounting cylinder 23. A magnetic column 55 is provided at one end of the combined mounting column 53 to attract the magnetic fixing block 34. An elastic mounting column 56 is provided at the other end of the combined mounting column 53. A combined mounting frame 57 is provided at the outer end of the elastic mounting column 56. A number of combined placement holes 58 are provided on the combined mounting frame 57. A number of rubber anti-slip rings 54 are provided on the outer side of the combined mounting column 53.

[0050] Insert the accessories into the combination placement hole 58 on the combination mounting bracket 57, and then insert the combination mounting column 53 in conjunction with the guide mounting cylinder 23. Fix the combination mounting bracket 57 containing the accessories onto the mounting partition 21. At this time, the magnetic column 55 and magnetic fixing block 34 at one end of the combination mounting column 53 attract and fix it, and the rubber anti-slip ring 54 can squeeze the inner wall of the guide mounting cylinder 23, restricting the axial rotation of the combination mounting column 53, further improving the stability of the installation and ensuring the safety of the accessories. If the consumables do not have high requirements for movement, they can be stacked at the bottom of the loading and mounting box 2 between the mounting partition 21 and the storage rotating cover 5. Due to the effect of the elastic mounting column 56, some vibration can be filtered out, further improving the safety of the accessories.

[0051] Multiple combination placement holes 58 can pre-arrange the order of accessories, facilitating subsequent connection operations and forming a modular sampling preprocessing;

[0052] Driven by the drive winding parts 17 at both ends, the transmission belt 35 is driven, which causes the transmission block 36 to move in conjunction with the transmission sleeve 37. Under the sliding guidance of the synchronous rotating shaft 32 and the sliding guide groove 38, the shear arm 12 is stably rotated, thereby realizing the lifting and lowering of the shear frame 39. The lifting and lowering of the shear frame 39 synchronously realizes the height adjustment of the sampling lifting plate 13.

[0053] When the sampling lifting plate 13 and the anti-interference sampling module on it are at the predetermined height, the combined installation column 53 is pulled out from the guide installation cylinder 23 and inserted into the loading cylinder shaft 33. The magnetic suction column 55 and the magnetic suction fixing block 34 at one end of the combined installation column 53 attract and fix it, and the rubber anti-slip ring 54 can squeeze the inner wall of the guide installation cylinder 23 to restrict the axial rotation of the combined installation column 53. At this time, the required accessories are selected for combination and installation. After the combination and installation is completed, one end is connected to the anti-interference sampling module, and the other end passes through the connecting installation cylinder 10 and is connected to the sampling equipment in the loading installation box 2. Then the sampling equipment is started to realize the sampling operation.

[0054] Example 4, based on Example 1, please refer to... Figures 7-10 In this embodiment of the invention, the anti-interference sampling module includes a transfer guide tube 29 disposed on the upper end of the sampling lifting plate 13. Two connecting guide tubes 30 are symmetrically disposed on the wall of the transfer guide tube 29. The ends of the connecting guide tubes 30 extend out of the sampling lifting plate 13. An opening and closing valve 42 is connected in series in the connecting guide tubes 30.

[0055] A spherical mounting cylinder 14 is provided above the transfer guide cylinder 29. A limiting rotating guide cylinder 48 is provided at the upper end of the transfer guide cylinder 29. A limiting rotating guide sleeve 28 is provided in cooperation with the spherical mounting cylinder 14 and the limiting rotating guide cylinder 48. The limiting rotating guide cylinder 48 and the limiting rotating guide sleeve 28 are rotated and cooperated by evenly arranged rotating beads 49. A detachable spherical mesh cover 47 is provided at one end of the limiting rotating guide cylinder 48 that extends into the spherical mounting cylinder 14. A detachable conical guide cylinder 44 is provided at one end of the spherical mounting cylinder 14 along the central horizontal axis. A sampling air inlet pipe 46 is connected to the end of the conical guide cylinder 44.

[0056] The spherical mounting cylinder 14 has a top flow column 27 at its other end along the central horizontal axis. The conical guide cylinder 44 has a plurality of guide vanes 31 arranged at equal angles on its exterior. One end of each guide vane 31 is fixed to the conical guide cylinder 44, and the other end of each guide vane 31 is inclined away from the conical guide cylinder 44. The ends of each guide vane 31 away from the conical guide cylinder 44 are provided with a flow channel 43. A guide hood 45 is provided on the outer wall of the conical guide cylinder 44 near the sampling air inlet pipe 46. A detachable air inlet screen 18 is provided at the outer end of the guide hood 45. The guide hood 45 and the air inlet screen 18 together cover the sampling air inlet pipe 46.

[0057] Install the air intake screen 18 on the air guide 45, and then install the conical air guide 44 on the spherical mounting cylinder 14. Then, start the sampling equipment. External air enters the conical air guide 44 through the air intake screen 18 and the sampling air intake pipe 46, and enters the transfer air guide 29 through the spherical screen 47 and the limiting rotation air guide 48. It is connected to the sampling equipment through the connecting air guide 30 connected to the accessory pipeline. The sampling is controlled by the opening and closing valve 42. It can realize the combination of multiple processing accessories, overcome the current situation of small number of outdoor sampling and processing accessories and inconsistent assembly, and realize the sampling of complex atmosphere.

[0058] When airflow is present at the sampling height, the force on one side of the spherical mounting cylinder 14 increases under the action of the guide plate 31 and its drainage groove 43. With the rotational cooperation of the limiting rotating guide cylinder 48 and the limiting rotating guide sleeve 28, the spherical mounting cylinder 14 is deflected to the top flow column 27 facing the airflow direction. At this time, the airflow acts on the top flow column 27, splitting the airflow at a certain angle. The faster the wind speed, the larger the angle of splitting, thereby reducing the influence of the airflow on the spherical mounting cylinder 14. When the remaining airflow flows through the guide plate 31, it is guided by the drainage groove 43 on it. The airflow at the end of the conical guide cylinder 44 is in a relatively stable state. At this time, when sampling through the sampling inlet pipe 46, the sample can be sufficiently accurate and stable, ensuring high-quality sampling.

[0059] During sampling, the air is filtered through the air intake mesh 18 and the spherical mesh 47, which avoids the influence of large particulate matter in the air on the sampling and improves the quality of atmospheric sampling.

[0060] Accessories may include glass sampling bottles, porous glass plate absorption tubes, impact absorption tubes, glass fiber filter cartridges, glass syringes, glass condensers, etc.

[0061] Example 5, based on Example 1, please refer to... Figure 4 , Figure 12 In this embodiment of the invention, the movable leveling mechanism includes a steering mounting column 20. One end of the steering mounting column 20 is fixed to the bottom of the movable mounting plate 1, and the other end of the steering mounting column 20 is provided with a leveling mounting frame 51. The leveling mounting frame 51 is provided with a swing telescopic arm 19 through a drive shaft 50. The outer end of the swing telescopic arm 19 is provided with a movable drive component 52 with an integrated lock. The movable drive component 52 is symmetrically provided with movable wheels 3 through a shaft.

[0062] Two mounting partitions 21 are symmetrically arranged on one side facing each other, and the battery packs 26 are connected in series through open wires 24. A power socket 40 is provided on the mounting partition 21. The battery packs 26 are electrically connected to the power socket 40, drive shaft 50, swing telescopic arm 19, moving drive component 52, and drive winding component 17 through internal wiring and open wires 24.

[0063] The device is moved by traction by connecting to an external traction power source through the traction ring 7. The traction power source can be a traction trolley or engineering equipment, etc.

[0064] The device can also be moved by driving the moving wheels 3 through the moving drive component 52. The leveling mounting frame 51 and its swing telescopic arm 19 can be rotated through the steering mounting column 20, thereby achieving steering movement. The angle of the swing telescopic arm 19 can be controlled by the drive shaft 50, and the length of the swing telescopic arm 19 can be adjusted to achieve the leveling operation of the moving mounting plate 1. This allows the moving mounting plate 1 to adapt to different terrains and always maintain a horizontal state, ensuring the stable operation of the sampling equipment and anti-interference sampling module on it, and improving the sampling quality.

[0065] Powered by the series connection of the battery pack 26, the device can operate independently outdoors for extended periods, thus expanding its application range.
