[0052] The atmospheric environment monitoring system of this embodiment will now be described.

[0053] In this embodiment, the atmospheric environment monitoring system may include the atmospheric environment monitoring air intake device described in the following embodiments.

[0054] It is understood that the atmospheric environment monitoring system of this embodiment also possesses the beneficial technical effects of the atmospheric environment monitoring air intake device of the following embodiments.

[0055] The following is combined Figures 1 to 8 The atmospheric environment monitoring air intake device of this embodiment will be described in detail.

[0056] Reference Figure 1 , Figure 2 and Figure 4 In this embodiment, the atmospheric environment monitoring air intake device may include an air intake base 100 and an air intake cap 300.

[0057] The top of the air intake base 100 has an air inlet 110 for collecting sample gas, and the bottom of the air intake base 100 is used to install it onto the target location of the environment to be monitored. The top of the air intake base 100 is provided with a first engaging structure 200, which is arranged circumferentially along the air inlet 110.

[0058] The air intake cap 300 is provided with a second engagement structure 400 corresponding to the first engagement structure 200. The second engagement structure 400 is engaged with the first engagement structure 200 so that the air intake cap 300 can be detachably covered on the air intake 110. The air intake cap 300 is used to restrict rainwater and dust from falling into the air intake 110. A first air intake part 120 is provided between the air intake cap 300 and the top of the air intake base 100, which communicates with and is open to the air intake 110.

[0059] In this embodiment, after the air intake base 100 is installed at the target position, the air intake cap 300 can be quickly assembled onto the air intake base 100 via the first engaging structure 200 and the second engaging structure 400, thus achieving assembly of the air intake cap 300 and the air intake base 100. Furthermore, the entire assembly process of the atmospheric environment monitoring air intake device is simple and efficient. Moreover, disassembly and reassembly during subsequent maintenance and repair are also very simple and quick. Additionally, the air intake cap 300 effectively prevents rainwater, dust, or other debris from falling into the air intake 110, effectively avoiding the impact of harsh environments on atmospheric monitoring. Therefore, this embodiment simplifies the installation of the atmospheric environment monitoring air intake device and the atmospheric environment monitoring system, reduces the maintenance cost of the atmospheric environment monitoring air intake device, improves the performance of the atmospheric environment monitoring air intake device against harsh environments, enhances the efficiency and flexibility of atmospheric monitoring work, ensures the accuracy of the monitoring results of the atmospheric monitoring system, and guarantees the quality and reliability of the monitoring data. Furthermore, the atmospheric environment monitoring air intake device of this embodiment can adapt to the needs of different monitoring scenarios. Whether in urban, industrial or rural environments, the atmospheric environment monitoring air intake device of this embodiment can be quickly deployed to ensure the continuity and efficiency of monitoring work.

[0060] Reference Figure 2 In this embodiment, the air inlet 110 can be configured to open upwards.

[0061] Reference Figure 1 and Figure 2 In this embodiment, the first engaging structure 200 can be arranged along the circumference of the air inlet 110, which can well ensure the connection stability of the air inlet cap 300 after it is connected to the first engaging structure 200 and the air inlet base 100 through the second engaging structure 400, so as to further improve the performance of the atmospheric environment monitoring air inlet device in resisting harsh environments.

[0062] Reference Figure 6 In this embodiment, the air intake base 100 may be provided with an air delivery channel 180 that connects to the air intake port 110, and the air delivery channel 180 extends from the air intake port 110 to the bottom of the air intake base 100. Furthermore, the air delivery channel 180 may be connected to the monitoring equipment of the atmospheric environment monitoring system to deliver the sampled gas to the monitoring equipment of the atmospheric environment monitoring system or other equipment.

[0063] In this embodiment, the air intake cap 300 and the air intake base 100 can be made of stainless steel.

[0064] Understandably, stainless steel provides better corrosion and wear resistance to atmospheric environmental monitoring intake devices, thereby extending the service life of the atmospheric environmental monitoring system and its intake devices, reducing the replacement frequency of the atmospheric environmental monitoring intake devices, and resulting in higher economic benefits.

[0065] Reference Figure 2 and Figure 3 In this embodiment, the first engaging structure 200 may include a plurality of engaging support plates 210 and a plurality of engaging insert plates 220.

[0066] Multiple locking plates 210 are connected to the air intake base 100, and the multiple locking plates 210 are arranged circumferentially along the air intake 110.

[0067] The bottom of each snap-fit ​​insert 220 is correspondingly connected to the snap-fit ​​support plate 210, and the top of each snap-fit ​​insert 220 extends upward.

[0068] It is understandable that by setting the first engaging structure 200 as multiple engaging support plates 210 and multiple engaging insert plates 220, the stability of the air intake cap 300 installed on the air intake base 100 can be ensured, while also allowing the first engaging structure 200 to have a lighter weight, so as to ensure the lightweight nature of the atmospheric environment monitoring air intake device.

[0069] Reference Figure 4 , Figure 5 , Figure 6 and Figure 7 In this embodiment, the second engaging structure 400 may include a plurality of engaging bodies 410.

[0070] Multiple snap-fit ​​bodies 410 are disposed on the air intake cap 300, corresponding to multiple snap-fit ​​inserts 220. Each snap-fit ​​body 410 has a first slot 411 that extends vertically and opens downwards, and the snap-fit ​​insert 220 is inserted into the first slot 411.

[0071] It is understandable that by connecting the first slot 411 and the snap-fit ​​plate 220, the snap-fit ​​connection of the first snap-fit ​​structure 200 and the second snap-fit ​​structure 400 can be realized, so as to achieve quick and easy assembly and disassembly of the air intake cap 300 and the air intake base 100.

[0072] In a modified embodiment of the first engaging structure 200 and the second engaging structure 400, the first engaging structure 200 and the second engaging structure 400 can each be a plurality of corresponding hooks and slots, and the plurality of hooks and slots are arranged circumferentially along the air inlet 110. The hooks are inserted into and engaged in the slots to achieve the same detachable connection between the air inlet cap 300 and the air inlet base 100. For example, the first engaging structure 200 is a hook arranged on the periphery of the air inlet 110 and extending upward, and the hook is positioned toward the central axis of the base (air inlet pipe 140). The second engaging structure 400 is a slot formed on the outer periphery of the air inlet cap 300 (cap sleeve 310), and the hook is engaged in the slot to achieve the snap-on and detachable connection of the first engaging structure 200 and the second engaging structure 400.

[0073] Reference Figure 7 In this embodiment, the top dimension of the locking plate 220 is smaller than the bottom dimension, and the size of the locking plate 220 gradually decreases from bottom to top. Specifically, the radial width of the top of the locking plate 220 in the air intake base 100 (air intake pipe 140) is smaller than the radial width of the bottom of the locking plate 220 in the air intake base 100 (air intake pipe 140). Therefore, after the locking plate 220 is inserted into the first slot 411, as the air intake cap 300 continues to assemble into the air intake base 100, the contact between the locking plate 220 and the inner wall of the first slot 411 becomes increasingly tight, ensuring the connection stability between the air intake cap 300 and the air intake base 100.

[0074] Reference Figure 5 In this embodiment, the air intake cap 300 may include a cap 310 extending in the vertical direction and a cap 320 connected to the top of the cap 310; and a locking body 410 is disposed on the outer peripheral side of the cap 310.

[0075] It is understandable that the locking body 410 is disposed on the outer periphery of the cap 310 to connect the air intake cap 300 and the air intake base 100. At the same time, the locking insert plate 220 can be located on the outer periphery of the air intake cap 300 to further ensure the stability of the air intake cap 300 installed on the air intake base 100.

[0076] Reference Figure 5 and Figure 6 In this embodiment, the longitudinal section of the cap 320 can be an arc shape with the center convex upward, so that rainwater, dust or other debris falling on the cap 320 can continue to fall smoothly, and avoid the accumulation of rainwater, dust or other debris on the air intake cap 300.

[0077] Reference Figure 2 , Figure 3 , Figure 6 and Figure 7In this embodiment, a clearance groove 230 with an upward and circumferential opening towards the cap 310 is provided between each locking insert plate 220 and each locking support plate 210; and the locking body 410 includes a first locking plate 412, a second locking plate 413 and a third locking plate 414 connected sequentially along the circumference of the cap 310. The first locking plate 412 and the third locking plate 414 are connected to the outer peripheral side of the cap 310, and the second locking plate 413 faces the cap 310 and is connected between the first locking plate 412 and the third locking plate 414. The first slot 411 is located between the first locking plate 412, the second locking plate 413, the third locking plate 414 and the cap 310; and the second locking plate 413 is inserted into the clearance groove 230.

[0078] Understandably, the clearance groove 230 allows the entire connection between the engaging support plate 210 and the engaging insert plate 220 to be installed in place, that is, the engaging insert plate 220 can be installed into the first slot 411. And the first slot 411 can be formed between the first engaging plate 412, the second engaging plate 413, and the third engaging plate 414 and the outer wall of the cap 310.

[0079] In a modified embodiment of the second engaging structure 400, the difference from the above embodiment is that the second engaging structure 400 may only include the second slot 241, and the first slot 411 may be directly formed on the air intake cap 300. Specifically, it may be formed on the wall of the cap 310.

[0080] In a modified embodiment where the locking body 410 is positioned, the locking body 410 may be located on the inner side of the cap 310. Similarly, the connection between the air intake cap 300 and the air intake base 100 can be achieved.

[0081] In a modified embodiment of the first engaging structure 200, the first engaging structure 200 may include an engaging ring disposed on the air intake base 100 and a plurality of engaging inserts 220 connected to the engaging ring, with the top of each engaging insert 220 extending upward. The engaging ring is fitted around the outer periphery of the air intake 110. The plurality of engaging inserts 220 are arranged circumferentially along the engaging ring. The engaging inserts 220 can also be inserted into the first slot 411, thus achieving the engaging connection between the first engaging structure 200 and the second engaging structure 400.

[0082] In this modified embodiment, the first air intake 120 may be a through hole formed on the retaining ring.

[0083] In another modified embodiment of the second engaging structure 400, unlike the second engaging structure 400 in the above embodiment, the engaging body 410 can be an annulus extending circumferentially along the cap 310 (set on the inner or outer sidewall of the cap 310). Furthermore, the first slot 411 can be formed on the engaging body 410. Similarly, the engaging connection between the first engaging structure 200 and the second engaging structure 400 can be achieved.

[0084] In this modified embodiment, the first air intake 120 may be a through hole formed on the locking body 410.

[0085] Reference Figures 1 to 8 In this embodiment, the number of multiple locking support plates 210, multiple locking insert plates 220 and locking body 410 (or first slot 411) can be three, so as to further ensure the connection stability of the air intake cap 300 and the air intake base 100, while making the first locking structure 200 lighter, further ensuring the lightweight nature of the atmospheric environment monitoring air intake device.

[0086] Reference Figure 2 In this embodiment, the air intake base 100 may include a delivery pipe 130 and an air intake pipe 140. The bottom end of the air intake pipe 140 is connected to the top end of the delivery pipe 130, and the air inlet 110 is located at the top end of the air intake pipe 140. The diameter of the air intake pipe 140 is smaller than the diameter of the delivery pipe 130.

[0087] It is understandable that by configuring the air intake base 100 with a delivery pipe 130 and an air intake pipe 140 of different diameters, and setting the diameter of the air intake pipe 140 to be smaller than that of the delivery pipe 130, the air intake base 100 can have a smaller air intake 110, and the air delivery channel 180 can be narrower at the air intake pipe 140. This further restricts rainwater, dust, or other debris from falling into the air intake 110, thereby further ensuring the accuracy of the atmospheric monitoring system's monitoring results, as well as the quality and reliability of the atmospheric monitoring system's monitoring data. Furthermore, the air delivery channel 180 can be wider at the delivery pipe 130 to ensure the smooth flow of the sampled gas within the delivery pipe 130.

[0088] Reference Figure 2 In this embodiment, multiple locking plates 210 can be evenly and lowly arranged in the circumference of the air intake base 100 (air intake pipe 140 or delivery pipe 130) to ensure the connection stability between the air intake cap 300 and the air intake base 100.

[0089] Reference Figure 2 In this embodiment, the air intake base 100 may further include a tapered tube 150. The tapered tube 150 is connected between the delivery tube 130 and the air intake tube 140.

[0090] It is understandable that the intake pipe 140 and the delivery pipe 130 can be connected by the tapered pipe 150. Specifically, the tapered pipe 150 with its smaller diameter is positioned upwards and connected to the bottom of the intake pipe 140, while the tapered pipe 150 with its larger diameter is positioned downwards and connected to the top of the delivery pipe 130. When rainwater, dust, or other debris slides from the intake pipe 140 to the delivery pipe 130, the tapered pipe 150 effectively ensures the mobility of rainwater, dust, or other debris, preventing them from falling onto the connection point between the intake pipe 140 and the delivery pipe 130.

[0091] Reference Figure 4 In this embodiment, the top of the air intake pipe 140 can extend into the cap 310. This further restricts rainwater, dust, or other debris from falling into the air intake 110, thereby further ensuring the accuracy of the atmospheric monitoring system's monitoring results, as well as the quality and reliability of the atmospheric monitoring system's monitoring data.

[0092] In some other implementations, the air intake cap 300 can be placed over the air intake 110, meaning the top of the air intake pipe 140 does not extend into the cap 310, in order to similarly restrict rainwater, dust or other debris from falling into the air intake 110.

[0093] Reference Figure 4 In this embodiment, the first air intake 120 is located between the air intake pipe 140 and the cap 310 and is open downwards. That is, the first air intake 120 can be the gap between the air intake pipe 140 and the cap 310, so that the gas in the environment to be monitored can enter the air intake 110 through the first air intake 120.

[0094] Reference Figure 2 In this embodiment, the bottom of the locking support plate 210 is connected to the outer wall of the delivery pipe 130, and the top of the locking support plate 210 extends upward to the top of the air intake pipe 140.

[0095] Understandably, due to the vertical extension of the intake pipe 140 and its small diameter, the locking support plate 210 can be connected to the delivery pipe 130 to ensure the connection stability between the intake cap 300 and the base. Furthermore, the top of the locking support plate 210 can extend upwards to the top of the intake pipe 140, allowing the locking insert plate 220 to be inserted into the first slot 411.

[0096] Reference Figure 2In this embodiment, the locking support plate 210 can be L-shaped. That is, the locking support plate 210 can include a first plate 211 extending in the vertical direction and a second plate 212 arranged radially in the conveying pipe 130. One end of the first plate 211 is connected to the outer arm of the conveying pipe 130, and the other end of the second plate 212 is connected to the bottom of the first plate 211. Thus, the locking support plate 210 can be connected to the conveying pipe 130 and extend in the vertical direction.

[0097] Reference Figure 2 In this embodiment, the longitudinal section of the second plate 212 can be triangular or parallelogram, so the second plate 212 can have a large width in the vertical direction, and thus the second plate 212 can be stably connected to the conveying pipe 130 and has good load-bearing capacity, so as to further ensure the connection stability of the air inlet cap 300 and the air inlet base 100.

[0098] Reference Figure 1 In this embodiment, the air intake base 100 may further include a connecting flange 160 and a reinforcing rib 170.

[0099] The connecting flange 160 is connected to the bottom of the delivery pipe 130 and is used to install it at the target location.

[0100] The reinforcing rib 170 is connected between the outer wall of the conveying pipe 130 and the connecting flange 160.

[0101] Understandably, the connecting flange 160 allows the entire atmospheric environment monitoring air intake device to be installed at the target location. Furthermore, the connecting flange 160 offers strong versatility and connection stability, further expanding the applicable scenarios for the atmospheric environment monitoring air intake device. The reinforcing rib 170 ensures the connection stability between the delivery pipe 130 and the connecting flange 160.

[0102] Reference Figure 1 , Figure 6 and Figure 7 In this embodiment, the atmospheric environment monitoring air intake device may further include a connecting cylinder 500.

[0103] The connecting cylinder 500 is detachably sleeved on multiple engaging support plates 210. The connecting cylinder 500 is used to maintain the engaging connection between the first engaging structure 200 and the second engaging structure 400.

[0104] Understandably, since a single engaging support plate 210 extends from the top of the delivery pipe 130 to the top of the intake pipe 140, its length in the vertical direction is relatively long. Furthermore, the thickness of the engaging support plate 210 in the circumferential direction of the intake pipe 140 or delivery pipe 130 can be set relatively thin to ensure the lightweight nature of the first engaging structure 200 and the atmospheric environment monitoring intake device. Therefore, the connecting cylinder 500, sleeved on the outside of the multiple engaging support plates 210, can ensure the overall stability of the multiple engaging support plates 210, thereby ensuring the stability of the engaging connection between the first engaging structure 200 and the second engaging structure 400, and further ensuring the connection stability between the intake cap 300 and the intake base 100.

[0105] Reference Figure 1 , Figure 6 and Figure 7 In this embodiment, the first engaging structure 200 may further include a plurality of engaging slot plates 240.

[0106] Multiple engaging slot plates 240 are correspondingly connected to the outer side of multiple engaging support plates 210. The multiple engaging slot plates 240 are located below the engaging insert plate 220, and the top of each engaging slot plate 240 extends upward. A second slot 241 with an upward facing and a circumferential opening in the connecting cylinder 500 is provided between each engaging slot plate 240 and each engaging support plate 210. The bottom edge of the connecting cylinder 500 is detachably inserted into the second slot 241.

[0107] It is understandable that the specific form of connection between the connecting cylinder 500 and the multiple locking support plates 210 may be that the lower edge of the connecting cylinder 500 is inserted into the second slot 241 formed on the locking support plate 210, so that the connecting cylinder 500 can be detachably sleeved on the multiple locking support plates 210.

[0108] Reference Figure 1 , Figure 6 and Figure 7 In this embodiment, the top of the connecting cylinder 500 can extend to the engaging insert plate 220, thereby limiting the insertion connection between the engaging insert plate 220 and the first slot 411. Specifically, it can cause the engaging insert plate 220 to have a tendency to bend towards the outer wall of the cap cylinder 310, so as to ensure the connection stability of the engaging insert plate 220 and the second slot 241.

[0109] Reference Figure 1 , Figure 6 , Figure 7 and Figure 8In this embodiment, the connecting cylinder 500 can be sleeved on the air intake pipe 140 of the air intake base 100 and the cap 310 of the air intake cap 300. A second air intake 510 with an upward opening is provided between the top of the connecting cylinder 500 and the cap 310. The second air intake 510 is connected to the first air intake 120. A third air intake 520 with a downward opening is provided between the bottom of the connecting cylinder 500 and the air intake pipe 140. The third air intake 520 is connected to the first air intake 120.

[0110] Understandably, the connecting cylinder 500, while ensuring the connection stability between the air inlet cap 300 and the air inlet base 100, can also be fitted onto the air inlet pipe 140 and the cap 310. That is, the connecting cylinder 500 is fitted onto the outside of the first air inlet portion 120 to further prevent rainwater, dust, or other debris from entering the air inlet 110, thereby further ensuring the accuracy of the atmospheric monitoring system's monitoring results and the quality and reliability of the atmospheric monitoring system's monitoring data. Furthermore, the connecting cylinder 500 has a second air inlet portion 510 and a third air inlet portion 520 between it and the air inlet cap 300 and the air inlet base 100, respectively, to ensure the flow of the sampled gas from the environment to be monitored into the air inlet 110.

[0111] Specifically, the second air intake 510 can be an upward-opening gap between the connecting cylinder 500 and the cap 310, and the third air intake 520 can be a downward-opening gap between the connecting cylinder 500 and the air intake pipe 140.

[0112] Reference Figures 1 to 8 In this embodiment, when assembling the atmospheric environment monitoring air intake device, the air intake base 100 is first installed at the target position via the connecting flange 160, and then the air intake cap 300 is connected to the air intake base 100 via the first engaging structure 200 and the second engaging structure 400. Finally, the connecting cylinder 500 is fitted onto the air intake cap 300, the air intake pipe 140 of the base, and the first engaging structure 200.

[0113] When maintenance is required on the atmospheric environment monitoring air intake device, first remove the connecting cylinder 500 from the first engaging structure 200, the air intake pipe 140, and the air intake cap 300 from bottom to top, and then remove the air intake cap 300 from the air intake base 100. Maintenance work can then be performed. After maintenance is completed, the air intake cap 300 and the connecting cylinder 500 can be reassembled according to the aforementioned assembly sequence.

[0114] Reference Figure 6In this embodiment, when the atmospheric environment monitoring system and its air intake device are working, the sampled gas can enter the connecting cylinder 500 from the second air intake 510 and the third air intake 520 respectively, and then converge in the first air intake 120 before flowing into the air inlet 110. Furthermore, the sampled gas flowing into the air inlet 110 can be transported to the monitoring equipment or other equipment of the atmospheric environment monitoring system through the gas delivery channel 180 in the base for detection and analysis.

[0115] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
