Description

Technical Field

[0001] This application relates to the technical field of air monitoring, and more particularly to an air monitoring device. Background Technology

[0002] Accurate air quality monitoring is fundamental to environmental management, public health early warning, and scientific research. Currently, air quality monitoring mainly relies on fixed stations to measure the concentrations of pollutants such as sulfur dioxide, nitrogen dioxide, ozone, and carbon monoxide in the atmosphere in real time or periodically.

[0003] Currently, traditional air quality monitors mostly employ a fixed vertical sampling method, where the sampling port faces vertically upwards, and multiple sampling tubes are located in the same area. Air below the sampling port is drawn into the instrument for analysis via pumping or diffusion. This design is simple and easy to deploy, but it has a fundamental technical flaw. The distribution of pollutants in the atmosphere is significantly non-uniform. Vertical sampling cannot capture air from different areas on the same horizontal plane. For non-uniformly distributed pollution sources, this can easily lead to multiple collected air samples having a similar composition, resulting in insufficient spatial representativeness and affecting the accuracy and reliability of the final measurement results. Summary of the Invention

[0016] Embodiments of this application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. Rather, embodiments of this application include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0017] The air monitoring device according to an embodiment of this application will now be described with reference to the accompanying drawings.

[0018] like Figures 1 to 5 As shown, the air monitoring device of this application embodiment may include a housing 1, an air collection component 3, a receiving component 4, a controller 5, and a detection mechanism 6.

[0019] The air collection component 3 is mounted on the housing 1 and is used to collect air from different directions.

[0020] It should be noted that the air monitoring device of this application can be installed in different locations via a column, and the installation height can be adjusted according to the surrounding environment (usually required to be between 3 and 15 meters above the ground). If monitoring pollution around roads, the installation height is usually 3-5 meters. If monitoring the ambient air of a certain area, the installation height is usually 3-15 meters to avoid excessive interference from nearby pollution sources such as ground dust and vehicle exhaust, and to better represent the average air quality of the breathing zone of the population.

[0021] Furthermore, the housing 1 is equipped with a door for easy maintenance and replacement of the collection bottle 42. The housing 1 is equipped with a wind direction sensor 2, which can monitor the wind direction at the current location (air monitoring location) in a timely manner and display it on a display screen (not shown in the figure) to understand the current wind direction in real time.

[0022] The receiving component 4 is located inside the housing 1 and is connected to the air collection component 3. The receiving component 4 includes a turntable 41, multiple collection bottles 42 and a limiting mechanism 43 for fixing the collection bottles 42. The turntable 41 is rotatably disposed inside the housing 1. The multiple collection bottles 42 are evenly distributed on the turntable 41 and are intermittently connected to the air collection component 3 and the detection mechanism 6 respectively. The limiting mechanism 43 is installed on the turntable 41.

[0023] In the embodiments of this application, the collection bottle 42 can receive air samples collected by the air collection component 3. Depending on the detection method, different specific reagents (such as formaldehyde buffer solution, etc.) can be placed in the collection bottle 42 to detect different harmful gases.

[0024] Furthermore, the turntable 41 is connected to an external drive mechanism (such as a motor) to drive the turntable 41 to rotate. The external drive mechanism is connected to a controller 5, which controls the turntable 41 to rotate intermittently, thereby collecting air samples from different directions, improving the diversity of air samples, and ensuring the accuracy and reliability of monitoring results.

[0025] The controller 5 is installed inside the housing 1 and is connected to the air collection component 3. The controller 5 is used to control the intermittent rotation of the air collection component 3 and the turntable 41.

[0026] In the embodiments of this application, the controller 5 can be electrically connected to the air collection component 3 via wired or wireless means. The controller 5 controls the air collection component 3 to rotate intermittently to collect air samples from different directions. The interval time can be set according to specific circumstances (to meet the time for air sampling and detection) and output to the controller 5 in advance.

[0027] To further clarify the above embodiments, in one embodiment of this application, such as Figure 2As shown, the air collection assembly 3 includes a collection tube 31, an air pump 32, a rotating assembly 33, an air guide tube 34, and a connecting tube assembly 35. The top of the housing 1 is provided with a protective shell 7. The air pump 32 is located inside the protective shell 7. The collection tube 31 is rotatably connected to the protective shell 7, and one end of the collection tube 31 is connected to the air inlet of the air pump 32. The rotating assembly 33 is located on the collection tube 31 and is connected to the controller 5. The air guide tube 34 and the connecting tube assembly 35 are both located inside the housing 1, and the connecting tube assembly 35 is connected to the air guide tube 34 and one of the collection bottles 42, respectively.

[0028] It should be noted that the rotating component 33 includes a motor and two meshing gears. The motor is installed inside the protective housing 7 and is electrically connected to the controller 5 to control the rotation angle of the motor output shaft. One gear is connected to the output end of the motor, and the other gear is fixed on the collection tube 31. The collection tube 31 is an L-shaped tube that extends outward and has a horn-shaped structure at one end to better collect air.

[0029] Furthermore, the collection bottle 42 is provided with an air inlet and an air outlet. The air inlet is connected to the connecting pipe assembly 35, and the air outlet is connected to the detection mechanism 6.

[0030] In one embodiment of this application, such as Figure 2 As shown, the connecting tube assembly 35 includes a first driving component 351 and a connecting tube 352. The inner wall of the housing 1 is provided with a mounting plate 8. The first driving component 351 is mounted on the mounting plate 8. The connecting tube 352 is connected to the output end of the first driving component 351 through a bracket. One end of the connecting tube 352 is connected to the air guide tube 34, and the other end of the connecting tube 352 is inserted into the corresponding collection bottle 42.

[0031] It should be noted that the first driving component 351 described in this embodiment can be an electric push rod, and the connecting pipe 352 includes a flexible hose and a rigid pipe that are connected to each other. One end of the flexible hose is connected to the connecting pipe 352, and the end of the rigid pipe is a frustum mechanism, which is convenient to be inserted into the corresponding collection bottle 42.

[0032] Furthermore, a sealing gasket is provided on the rigid tube. When one end of the rigid tube is inserted into the collection bottle 42, the sealing gasket fits tightly against the air inlet of the collection bottle 42, thereby improving the sealing effect.

[0033] Specifically, when the turntable 41 drives the collection bottle 42 to rotate, one of the collection bottles 42 is located at the bottom of the connecting tube 352. At this time, the relevant personnel control the first driving component 351 to start. The first driving component 351 drives the connecting tube 352 to move down and inserts one end of the rigid tube into the collection bottle 42. Then, the shut-off valve at the air inlet is opened, and the collected air is delivered into the collection bottle 42.

[0034] In one embodiment of this application, such as Figure 4 As shown, the limiting mechanism 43 includes an abutment plate 431 and multiple sets of clamping components 432. The abutment plate 431 is rotatably disposed at the center of the turntable 41, and multiple arc-shaped plates are evenly distributed on the abutment plate 431. The multiple sets of clamping components 432 are arranged in a circular array and abut against the arc-shaped plates respectively.

[0035] It should be noted that, see Figure 2 A support plate is provided above the turntable 41 to support the motor connected to the turntable 41. The clamping assembly 432 is used to fix the collection bottle 42 to prevent the collection bottle 42 from shifting during the rotation of the turntable 41.

[0036] Further, if Figure 4 As shown, the clamping assembly 432 includes a spring 4321, a first limiting plate 4322 and a second limiting plate 4323 located on both sides of the collection bottle 42. The turntable 41 is provided with a limiting ring 9. The two ends of the spring 4321 are respectively connected to the limiting ring 9 and the first limiting plate 4322. The upper surface of the turntable 41 is provided with multiple sliding grooves. A slider 10 is slidably connected in the sliding groove. The second limiting plate 4323 is set on the slider 10 and abuts against the arc plate.

[0037] It should be noted that the extension of the chute passes through the center of the turntable 41. The chute guides the movement direction of the second limiting plate 4323, ensuring that the second limiting plate 4323 and the first limiting plate 4322 can stably clamp the collection bottle 42.

[0038] Furthermore, the side of the first limiting plate 4322 and the second limiting plate 4323 adjacent to the collection bottle 42 are both arc-shaped surfaces. The arc-shaped surfaces fit the collection bottle 42 better and the fixing effect is better. When the first limiting plate 4322 and the second limiting plate 4323 abut against the outer wall of the collection bottle 42, the spring 4321 is in a compressed state.

[0039] Specifically, when multiple collection bottles 42 are evenly placed on the turntable 41, the relevant personnel control the motor to start, which drives the abutment plate 431 and the arc plate to rotate. During the rotation of the arc plate, the second limiting plate 4323 is continuously squeezed to move centrifugally (moving away from the center of the turntable 41), and pushes the collection bottles 42 to move. Finally, the spring 4321 is compressed, and the collection bottle 42 is clamped between the first limiting plate 4322 and the second limiting plate 4323, thus achieving the simultaneous fixation of multiple collection bottles 42.

[0040] In one embodiment of this application, such as Figure 5As shown, the detection mechanism 6 is provided with a second driving component 11, and the output end of the second driving component 11 is provided with a connecting plate 12. The connecting plate 12 is connected to the air inlet pipe 13 of the detection mechanism 6, and the end of the air inlet pipe 13 is inserted into the exhaust port of the corresponding collection bottle 42.

[0041] It should be noted that the second driving component 11 can be an electric push rod, the connecting plate 12 can be a telescopic tube, and the second driving component 11 can drive the air inlet pipe 13 to be inserted into the exhaust port, and draw the air in the collection bottle 42 into the detection mechanism 6 through the detection mechanism 6 for air detection. It is understood that the detection principle and detection method of the detection mechanism 6 are common knowledge in the field, and will not be described in detail in this application.

[0042] Furthermore, the results monitored by the testing agency 6 can be displayed on a screen (not shown in the figure) to provide real-time information on the air quality at the current location.

[0043] Specifically, when conducting air monitoring, relevant personnel can install this device on a column. After starting the device, the air pump 32 starts working, the collection tube 31 collects air samples from the first direction and delivers them to the collection bottle 42 at the first position. Subsequently, the detection agency 6 analyzes the first air sample in the collection bottle 42.

[0044] Then, controller 5 activates the first drive unit 351 and the second drive unit 11. The first drive unit 351 causes the connecting pipe 352 to separate from the air inlet of the collection bottle 42, and the second drive unit 11 causes the air inlet pipe 13 to separate from the exhaust port of the collection bottle 42. Next, controller 5 controls the rotating assembly 33 and the turntable 41 to rotate at a specific angle, adjusting the collection pipe 31 to a second direction. Simultaneously, the other collection bottle 42 rotates to the first position. Afterward, the first drive unit 351 controls the connecting pipe 352 to insert into the air inlet of the collection bottle 42, and the second drive unit 11 controls the air inlet pipe 13 to insert into the exhaust port of the collection bottle 42.

[0045] At this time, the controller 5 restarts the air pump 32, the collection tube 31 collects air samples from the second direction, and the detection mechanism 6 detects the second air sample. This process is repeated to achieve automatic collection of air samples from multiple directions, which significantly improves sample diversity and ensures the reliability and accuracy of monitoring results.

[0046] In summary, the air monitoring device of this application embodiment achieves 360-degree multi-point air collection by driving the sampling tube to rotate intermittently, which effectively improves the diversity of air samples and thus ensures the accuracy and reliability of monitoring results.
