Description

An intelligent Internet of Things (IoT) air sampling device for air environment monitoring Technical Field

[0001] This invention belongs to the field of air detection equipment technology, and in particular relates to an air sampling device for intelligent Internet of Things air environment monitoring. Background Technology

[0002] Air environment monitoring involves collecting data on air pollutants through air sampling to assess air quality and environmental pollution levels. Air sampling can identify and quantify the sources and concentrations of pollutants in the air, helping to identify pollution sources, assess the potential health risks of pollutants, and conduct environmental risk assessments. Through monitoring, pollution events or trends that may impact human health and the ecological environment can be detected and addressed in a timely manner.

[0003] In the prior art, Chinese patent publication number "CN218411893U" discloses an air sampling device for intelligent IoT air environment monitoring. This device samples air through a sampling head, and the sampled air is automatically analyzed by an air analyzer via a flexible hose, transmitting the data back to the operator's information processing equipment. When collecting air at different heights, rotating a handle rotates a rotating shaft. This rotation, along with two oppositely arranged external threaded grooves on the shaft's surface, causes two moving blocks to move towards or away from each other, which in turn rotates two connecting rods. This, in turn, moves the fixed box vertically, allowing adjustment of the sampling head's height. This solves the problem of limited height in existing environmental monitoring air sampling devices, which cannot adjust the height and sampling angle, thus limiting their ability to collect air at different levels.

[0004] However, the above-mentioned device still has the following problems during implementation:

[0005] When sampling air using a sampling head, only a single location can be sampled once. The concentration of air pollutants varies at different locations. Continuity is key to assessing environmental quality and monitoring trends. A single sampling cannot provide continuous data points, and the provided sampling data is relatively limited, making it difficult to accurately verify test results, thus reducing the credibility and scientific value of the data.

[0006] To address these issues, we provide an intelligent IoT-based air sampling device for air environment monitoring.

[0007] Summary of the Invention

[0012] The top of the sampling shell is provided with a telescopic component, which includes a movable tube. The top of the movable tube is connected to a corrugated pipe, and a solenoid valve is sleeved on the surface of the corrugated pipe. The telescopic component is used to extract air from inside the sampling shell.

[0013] A drive assembly is provided on the front side of the support frame, and the position of the sampling shell is adjusted by the drive assembly;

[0014] The support frame is equipped with an adjustment component, which can be used to adjust the angle of the sampling shell.

[0015] The present invention is further configured such that the top of the one-way tube is connected to the sampling bag, and the other end of the corrugated tube is connected to the sampling shell.

[0016] The present invention is further configured such that the telescopic component also includes a sealing plug, the sealing plug being slidably connected inside the movable tube, a movable rod being fixedly connected to the bottom of the sealing plug, and a first spring and a tension spring being respectively sleeved on the surface of the movable rod.

[0017] The present invention is further configured such that the bottom end of the moving rod is fixedly connected to the sampling shell, the top and bottom ends of the first spring are fixedly connected to the moving tube and the sampling shell respectively, and the top and bottom ends of the tension spring are fixedly connected to the sealing plug and the inner wall of the sampling shell respectively.

[0019] The present invention is further configured such that the adjusting component includes a movable plate, a support shaft is movably connected inside the movable plate, a gear is fixedly connected to the surface of the support shaft, a toothed plate is meshed on one side of the gear, an adjusting plate is sleeved on the surface of the toothed plate, and one side of the adjusting plate extends through into the interior of the support frame and is fixedly connected to the movable plate.

[0020] The present invention is further configured such that one side of the support shaft is fixedly connected to the moving tube, and the other side of the moving plate extends through the drive box and is fixedly connected to the threaded sleeve.

[0021] The invention is further configured such that a slide rod is fixedly connected to one side of the toothed plate, the bottom of the slide rod passes through the adjusting plate, and a second spring is sleeved on the surface of the slide rod.

[0025] 1. This invention uses a sampling component to sample ambient air in multiple groups. Multiple sampling bags can store multiple air samples from the same location, increasing the accuracy of air data comparison. At the same time, the bottom of the sampling bag is controlled by a valve to allow only one-way entry of external air into the sampling bag, preventing gas leakage and improving the accuracy of ambient air detection.

[0026] 2. By setting up a telescopic component, the present invention can increase the sampling height of the sampling shell by using a moving tube and a moving rod. Through the pulling force of the first spring and the tension spring, the sampling shell can be pushed to sample air at different positions. At the same time, when the sealing plug moves, the air inside the sampling shell can be extracted, so that the inside of the sealing shell is kept in a negative pressure state. Through the action of air pressure, the external air is drawn into the sampling bag, thereby realizing the function of automatic sampling.

[0027] 3. By setting the drive component, the position of the sampling shell can be adjusted, and the sampling shell can be raised to different heights for sampling. By setting the adjustment component, when the sampling shell moves upward and contacts the baffle, the toothed plate can be prevented from moving upward further, so that the toothed plate drives the gear to rotate, thereby adjusting the angle of the sampling shell, which is convenient for sampling air at different heights and angles.

[0028] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A mounting hole 9 is provided on the top of the turntable 8, and a one-way tube 10 is threaded into the mounting hole 9. A valve disc 11 is fixedly connected inside the one-way tube 10, allowing for multiple grouped sampling of ambient air by the sampling component. A telescopic component, including a moving tube 12, is also provided on the top of the sampling shell 3.

Second spring 29 and first spring 17 both have the function of compression and energy storage. Second spring 29 can reset toothed plate 26. Toothed plate 26 drives gear 25 to rotate again, resetting sampling shell 3.

[0048] Specific Implementation Example 3

[0049] Please refer to Figures 1-10. Based on the first specific embodiment, the adjustment component includes a movable plate 23. A support shaft 24 is movably connected inside the movable plate 23. A gear 25 is fixedly connected to the surface of the support shaft 24. A toothed plate 26 meshes with one side of the gear 25. An adjustment plate 27 is sleeved on the surface of the toothed plate 26. One side of the adjustment plate 27 extends into the interior of the support frame 2 and is fixedly connected to the movable plate 23. One side of the support shaft 24 is fixedly connected to the movable tube 12.

A slide rod 28 is fixedly connected to one side of the toothed plate 26. The bottom of the slide rod 28 extends through the adjustment plate 27. A second spring 29 is sleeved on the surface of the slide rod 28. Mounting seats 30 are fixedly connected to both sides of the sealing seat 5. A fixing screw 31 extends through the bottom of the mounting seat 30. The top of the fixing screw 31 is threadedly connected to the sampling shell 3. A baffle 32 is fixedly connected to the top of the support frame 2. The air monitoring component includes an environmental sensor, a meteorological sensor, a temperature and humidity sensor, a communication module, a cloud data storage module, and a remote monitoring module.

[0050] Specifically: Environmental sensors: sensors used to measure various pollutants in the air, such as particulate matter (PM), nitrogen dioxide (NO2), carbon monoxide (CO), and ozone (O3). Meteorological sensors: used to measure environmental parameters such as temperature, humidity, and wind speed. These parameters can affect the formation and spread of air quality. The data collected by the sensors is processed and analyzed in real time by a microprocessor or embedded system. Data processing includes calibration, noise reduction, and data formatting to ensure the accuracy and reliability of the collected data. The collected data is transmitted to the cloud or local server via wireless communication technology. Commonly used communication technologies include Wi-Fi, cellular networks (such as 4G / 5G), LoRaWAN, and NB-IoT. The communication module can be customized according to the location, coverage area, and data volume of the monitoring equipment. Based on transmission requirements, data is sent to cloud storage for database management and analysis. Cloud platforms typically provide data storage, real-time monitoring, remote access, and analysis tools, allowing users to view and analyze monitoring data at any time. Users can monitor air quality data, trends, and alarm status in real time through web pages or mobile applications. The system can set alarm thresholds, and when air quality exceeds preset safety levels, the system will send an alarm to notify relevant personnel. Through IoT technology, air monitoring equipment can achieve real-time monitoring, remote access, data analysis, and intelligent decision support, greatly improving monitoring efficiency and data availability. This helps to better protect public health and environmental quality and is a mature existing technology used to detect the current air conditions to determine whether the ambient air meets sampling standards.

[0051] The working principle of this invention is as follows: After the staff moves the device to the designated sampling position, the servo motor 20 is started by the external controller. The servo motor 20, together with the threaded rod 21, drives the threaded sleeve 22 to move. The threaded sleeve 22, together with the moving plate 23, drives the support shaft 24 to move. The support shaft 24 drives the moving tube 12 to move downward. At this time, the tension spring 18 pulls the sealing plug 15, and the first spring 17 elastically resets the sampling shell 3. While the sealing plug 15 moves, it works with the bellows 13 to extract the air inside the sampling shell 3.

[0052] Continue to control the servo motor 20 to drive the sampling shell 3 to move upward. While the moving plate 23 moves, it also drives the adjusting plate 27 and the toothed plate 26 to move. When the toothed plate 26 contacts the baffle 32, the baffle 32 prevents the toothed plate 26 from moving further. Then, continue to control the servo motor 20 to drive the moving plate 23 to move upward. The moving plate 23 drives the gear 25 to rotate on the surface of the toothed plate 26. The gear 25, in conjunction with the support shaft 24, drives the moving tube 12 and the sampling shell 3 to rotate, so that the sampling shell 3 can rotate to different angles and heights for sampling.

[0053] After the sampling shell 3 rotates to the designated height, the drive motor 7 is started. The drive motor 7 drives the turntable 8 to rotate. The turntable 8 drives the one-way tube 10 to connect with the air inlet 6. Since the inside of the sampling shell 3 is in a negative pressure state, external air can be drawn into the sampling bag 4 for storage. The one-way tube 10 is controlled unidirectionally through the valve 11. When it is necessary to perform secondary sampling at different locations, the drive motor 7 can be started again to drive the turntable 8 to rotate, so that the next set of sampling bags 4 can connect with the air inlet 6 for secondary sampling. This can effectively improve the sampling efficiency and increase the accuracy of the sampling data through multiple sets of air sample data.

[0054] All standard parts used in this invention can be purchased from the market, and can also be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through the control unit.
