Description

Technical Field

[0001] This utility model relates to the field of atmospheric sampling device technology, and in particular to an atmospheric sampling device for environmental monitoring. Background Technology

[0002] Environmental monitoring refers to the activities of environmental monitoring agencies in monitoring and measuring the status of environmental quality. Environmental monitoring determines the level of environmental pollution and quality by monitoring and measuring indicators that reflect environmental quality. The content of environmental monitoring mainly includes the monitoring of physical indicators, chemical indicators, and ecosystems. Traditional atmospheric sampling devices used for environmental monitoring can generally only collect data in one specific way, resulting in poor continuity and inconvenience in data collection.

[0003] Chinese utility model patent CN219552004U discloses an atmospheric sampling device for environmental monitoring, including a working frame with several gas collection bags on it. Each gas collection bag has an air inlet pipe with an air inlet hole and an air outlet hole. An air inlet valve is located in the air inlet hole, and an air outlet valve is located in the air outlet hole. The air outlet hole communicates with the gas collection bags. A piston is located inside the air inlet pipe, with its circumferential sidewall abutting against the inner wall of the air inlet pipe and movable within it. A pull rod is fixed to the piston, with one end of the pull rod extending out of the air inlet pipe. Both the air inlet hole and the air outlet hole are located on the side of the piston furthest from the pull rod.

[0004] The above technical solution also has the following drawbacks: when the device collects atmospheric data, it can only collect data from a single altitude at a time, resulting in a relatively uniform atmospheric sample that cannot accurately monitor the atmospheric environment of the area, thus increasing monitoring errors. Utility Model Content

[0005] To address the aforementioned problems, this invention provides an atmospheric sampling device for environmental monitoring.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an atmospheric sampling device for environmental monitoring, comprising a flatbed cart, an air pump fixed on the flatbed cart, an air inlet end of the air pump fixed and connected to a telescopic pipe, an electric push rod fixed on the flatbed cart, the push rod end of the electric push rod fixed to the telescopic pipe, an air outlet end of the air pump fixed and connected to an exhaust pipe, and a collection mechanism provided on the flatbed cart for collecting the gas discharged from the air pump into the exhaust pipe.

[0007] By adopting the above technical solution, after the air pump is working, the outside air will be discharged into the exhaust pipe through the telescopic tube and the air pump in sequence. Finally, the gas in the exhaust pipe will be collected by the collection mechanism for subsequent gas composition analysis. In addition, after the electric push rod is working, its push rod extends or retracts, thereby causing the telescopic tube connected to the electric push rod to extend or retract, thus changing the suction height of the telescopic tube and collecting gas at multiple heights, which improves the accuracy of atmospheric environment monitoring.

[0008] Furthermore, the collection mechanism includes a collection component, which includes a mounting plate fixed to a flatbed truck, multiple air supply pipes extending through the mounting plate, an L-shaped sliding plate slidably mounted on the flatbed truck, an air bag placed on the horizontal section of the sliding plate, and an air inlet pipe fixed and connected to the air bag. All the multiple air supply pipes are fixedly connected to an exhaust pipe. Each air supply pipe is equipped with a switch valve. The vertical section of the sliding plate has a U-shaped structure. The air inlet pipe is inserted into the vertical section of the sliding plate and is inserted into the mounting plate. A one-way valve is provided on the air inlet pipe. The collection mechanism also includes a moving component for driving the multiple sliding plates to move synchronously.

[0009] By adopting the above technical solution, the gas in the exhaust pipe enters the gas bag in sequence through the air supply pipe and the air intake pipe for collection. After collection, multiple sliding plates are driven by the moving component until the air intake pipe and the air supply pipe are separated. At this time, multiple gas bags can be removed one by one from the corresponding sliding plates, which facilitates the use of the device.

[0010] Furthermore, the moving component includes a connecting rod disposed on a sliding plate, an adjusting plate slidably disposed on a flatbed cart, a threaded post threaded through and threadedly connected to the flatbed cart, and a knob fixed to the threaded post. The connecting rod is slidably disposed on the flatbed cart, and the threaded post is rotatably connected to the adjusting plate. The adjusting plate has an adjusting through hole through which the connecting rod passes and slides. The distance between the adjusting through hole and the mounting plate gradually decreases from the knob to the threaded post. The collecting mechanism also includes a limiting component for improving the stability of the adjusting plate and the connecting rod during movement.

[0011] By adopting the above technical solution, rotating the knob drives the threaded column to rotate. Since the threaded column is threadedly connected to the flatbed truck, it drives the adjustment plate, which is rotatably connected to the threaded column, to move. Since the distance between the adjustment through hole and the mounting plate gradually decreases from the knob to the threaded column, the connecting rod, which is slidably connected to the adjustment through hole, moves towards or away from the mounting plate, thereby achieving the purpose of connecting or separating the air intake pipe and the air supply pipe.

[0012] Furthermore, the limiting assembly includes a guide rod fixed to the flatbed, a connecting block fixed to the adjusting plate, a limiting slider fixed to the lower end of the connecting rod, and a limiting rod that passes through and slides on the limiting slider. The guide rod passes through the connecting block and slides. The top of the flatbed has a groove that slides with the limiting slider. The limiting rod is fixed in the groove. The number of connecting rods, grooves, limiting rods, limiting sliders, and sliding plates are all equal and their positions correspond one-to-one.

[0013] By adopting the above technical solution, when the connecting rod moves, the limiting slider moves along the side wall of the limiting rod in the slide groove, and when the adjusting plate moves, the connecting block slides along the side wall of the guide rod, thereby improving the stability of the movement of the adjusting plate and the connecting rod.

[0014] Furthermore, the horizontal section of the sliding plate is provided with a sliding through hole, and the sliding plate is provided with a displacement component. The displacement component includes a threaded rod rotatably installed in the sliding through hole, a guide slider slidably installed in the sliding through hole, and an adjusting column fixed on the threaded rod. The threaded rod passes through the guide slider and is threadedly connected to it. The guide slider is fixed to the upper end of the connecting rod.

[0015] By adopting the above technical solution, the rotating adjustment column drives the threaded rod to rotate. Since the threaded rod is threadedly connected to the guide slider, both the threaded rod and the sliding plate connected to the threaded rod move, thus achieving the purpose of disassembling or installing a single air bag.

[0016] Furthermore, an annular baffle is fixed inside the air supply pipe, and an annular pad is fixed at one end of the air intake pipe near the mounting plate, with the annular pad abutting against the annular baffle.

[0017] By adopting the above technical solution, the installation of the annular baffle and annular gasket improves the sealing performance when the air intake pipe is connected to the air supply pipe.

[0018] Furthermore, anti-slip strips are fixed on the side walls of both the adjusting column and the knob.

[0019] By adopting the above technical solution, the anti-slip strip reduces the probability of slippage when the adjustment column or knob is rotated.

[0020] In summary, this utility model has the following beneficial effects: In this application, by setting an electric push rod and a telescopic tube, gas collection at multiple heights is achieved, thereby improving the accuracy of atmospheric environment monitoring. Attached Figure Description

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] like Figure 1-4 As shown in the illustration, this application discloses an atmospheric sampling device for environmental monitoring, including a flatbed trolley 1, a collection mechanism 6, and a displacement assembly 8. An air pump 2 is fixed to the flatbed trolley 1. The air inlet of the air pump 2 is fixed and connected to a telescopic pipe 3, and an electric push rod 4 is fixed to the flatbed trolley 1. The push rod end of the electric push rod 4 is fixed to the telescopic pipe 3, and the air outlet of the air pump 2 is fixed and connected to an exhaust pipe 5. By adopting the above technical solution, after the air pump 2 operates, outside air is sequentially discharged through the telescopic pipe 3 and the air pump 2 into the exhaust pipe 5. Finally, the collection mechanism 6 collects the gas in the exhaust pipe 5 for subsequent gas composition analysis. Furthermore, after the electric push rod 4 operates, its push rod extends or retracts, thereby causing the telescopic pipe 3 connected to the electric push rod 4 to extend or retract, thus changing the air intake height of the telescopic pipe 3 and collecting gas at multiple heights, improving the accuracy of atmospheric environmental monitoring.

[0028] The collection mechanism 6 is mounted on the flatbed trolley 1 and includes a collection component 61, a moving component 62, and a limiting component 63. The collection component 61 includes a mounting plate 611, an air supply pipe 612, a sliding plate 613, an air bag 614, and an air inlet pipe 615. The mounting plate 611 is fixed to the flatbed trolley 1, and multiple air supply pipes 612 are provided through the mounting plate 611. All multiple air supply pipes 612 are fixedly connected to the exhaust pipe 5, and a switch valve is provided on each air supply pipe 612. The sliding plate 613 is slidably mounted on the flatbed trolley 1 and is L-shaped. The vertical section of the sliding plate 613 has a U-shaped structure, and the air bag 614 is placed on the horizontal section of the sliding plate 613. The air inlet pipe 615 is fixed and connected to the air bag 614, and a one-way valve is provided on the air inlet pipe 615. The number of air supply pipes 612, sliding plates 613, air bags 614, air inlet pipes 615, and switch valves are equal and their positions correspond one-to-one. The air inlet pipe 615 is inserted into the vertical section of the sliding plate 613, and the air inlet pipe 615 passes through the mounting plate 611 and is inserted into it. The gas in the exhaust pipe 5 enters the air bag 614 through the air supply pipe 612 and the air inlet pipe 615 in sequence for collection. After collection, the moving component 62 drives the multiple sliding plates 613 to move until the air inlet pipe 615 separates from the air supply pipe 612. At this time, the multiple air bags 614 can be removed one by one from the corresponding sliding plate 613 for easy use of the device.

[0029] The moving assembly 62 is used to drive multiple sliding plates 613 to move synchronously. The moving assembly 62 includes a connecting rod 621, an adjusting plate 622, a threaded post 623, and a knob 624. The connecting rod 621 is disposed on the sliding plate 613 and slidably disposed on the flatbed trolley 1. The adjusting plate 622 is slidably disposed on the flatbed trolley 1. An adjusting through hole 625 is provided through the adjusting plate 622 for the connecting rod 621 to pass through and slide. The distance between the adjusting through hole 625 and the mounting plate 611 gradually decreases from the knob 624 to the threaded post 623. The threaded post 623 is disposed through the flatbed trolley 1 and threadedly connected. The threaded post 623 is rotatably connected to the adjusting plate 622, and the knob 624 is fixed to the threaded post 623. Rotating the knob 624 causes the threaded post 623 to rotate. Since the threaded post 623 is threadedly connected to the flatbed 1, it drives the adjusting plate 622, which is rotatably connected to the threaded post 623, to move. As the distance between the adjusting through hole 625 and the mounting plate 611 gradually decreases from the knob 624 to the threaded post 623, the connecting rod 621, which is slidably connected to the adjusting through hole 625, moves closer to or further away from the mounting plate 611, thereby achieving the purpose of connecting or separating the air intake pipe 615 and the air supply pipe 612.

[0030] The limiting component 63 is used to improve the stability of the adjustment plate 622 and the connecting rod 621 during movement. The limiting component 63 includes a guide rod 631, a connecting block 632, a limiting slider 633, and a limiting rod 634. The guide rod 631 is fixed to the flatbed 1 and passes through the connecting block 632 and slides in engagement with it. The connecting block 632 is fixed to the adjustment plate 622. The limiting slider 633 is fixed to the lower end of the connecting rod 621. The top of the flatbed 1 has a groove 635 that slides in engagement with the limiting slider 633. The limiting rod 634 is fixed in the groove 635 and passes through the limiting slider 633 and slides in engagement with it. The number of connecting rods 621, grooves 635, limiting rods 634, limiting sliders 633, and sliding plates 613 are all equal and their positions correspond one-to-one. When the connecting rod 621 moves, the limiting slider 633 moves along the side wall of the limiting rod 634 in the slide groove 635, and when the adjusting plate 622 moves, the connecting block 632 slides along the side wall of the guide rod 631, thereby improving the stability of the movement of the adjusting plate 622 and the connecting rod 621.

[0031] A sliding through hole 7 is provided through the horizontal section of the sliding plate 613, and a displacement component 8 is disposed on the sliding plate 613. The displacement component 8 includes a threaded rod 81, a guide slider 82, and an adjusting column 83. The threaded rod 81 is rotatably installed in the sliding through hole 7. The threaded rod 81 passes through the guide slider 82 and is threadedly connected to it. The guide slider 82 is slidably disposed in the sliding through hole 7. The guide slider 82 is fixed to the upper end of the connecting rod 621, and the adjusting column 83 is fixed to the threaded rod 81. Rotating the adjusting column 83 drives the threaded rod 81 to rotate. Since the threaded rod 81 is threadedly connected to the guide slider 82, both the threaded rod 81 and the sliding plate 613 rotatably connected to the threaded rod 81 move, thereby enabling the disassembly or installation of a single air bag 614.

[0032] An annular baffle 9 is fixed inside the air supply pipe 612, and an annular gasket 10 is fixed at one end of the air intake pipe 615 near the mounting plate 611. The annular gasket 10 abuts against the annular baffle 9. The annular baffle 9 and the annular gasket 10 improve the sealing performance when the air intake pipe 615 is connected to the air supply pipe 612.

[0033] Anti-slip strips are fixed to the side walls of both the adjusting column 83 and the knob 624. The anti-slip strips reduce the probability of slippage when the adjusting column 83 or the knob 624 is rotated.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
