Description

Technical Field

[0001] This disclosure relates to the field of gas pollution monitoring devices, and more particularly to an air pollution monitoring device based on wireless data transmission. Background Technology

[0002] Air pollution is becoming increasingly serious, having a wide-ranging and profound impact on human health, the ecological environment, and socio-economic development. Accurate and timely monitoring of air pollution is crucial for formulating effective environmental protection policies, implementing targeted control measures, and safeguarding public health.

[0003] Most existing air pollution monitoring devices can only monitor dust in the air. If it is necessary to detect specific components in the air, air samples usually need to be taken and sent to a laboratory for accurate testing. This results in low detection efficiency and high labor costs for manual sampling. It is also inconvenient to sample and test air at different altitudes. Furthermore, existing detection devices are all fixed at one location for continuous detection, which cannot provide accurate data support for hourly changes in air pollution, such as dust pollution during morning and evening rush hours and industrial emissions at night. This makes it difficult to meet the requirements for refined monitoring of air pollution. The detection probes are directly exposed to the atmospheric environment and are easily affected by the surrounding environment, which affects the accuracy and reliability of the detection results.

Air composition detection structures can directly monitor the composition of the air, eliminating the need for manual sampling and sending samples to the laboratory for analysis. This improves the accuracy of air composition detection, reduces labor costs, increases the efficiency of air composition detection, and prevents delays in air quality detection.

[0042] Embodiments of this disclosure 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 are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0043] like Figures 1 to 11 As shown in the figure, this disclosure proposes an air pollution monitoring device based on wireless data transmission, including: a base 101, on which an adjustment structure is mounted, a wind direction detection structure and an air quality monitoring structure are mounted, and a power generation structure is mounted on the adjustment structure; an air composition detection structure, which corresponds to the air quality monitoring structure; a drive structure and an energy storage structure are mounted inside the base 101, the energy storage structure corresponding to the power generation structure, the drive structure corresponding to the adjustment structure and the air quality monitoring structure; and a locking structure is mounted on the base 101, which corresponds to the adjustment structure and the drive structure.

[0044] In this embodiment, the adjustment structure includes a support rod 102, which includes a first rod body 103 and a second rod body 104. The first rod body 103 and the second rod body 104 are slidably connected. The first rod body 103 is rotatably connected to the base 101. A rain cover 105 is fixed to the top of the first rod body 103, and the rain cover 105 corresponds to the base 101. A connector 106 is fixed to the top of the second rod body 104, and the connector 106 corresponds to the wind direction detection structure, the air quality monitoring structure, and the power generation structure.

[0045] Specifically, by sliding the second rod 104 up and down within the first rod 103, the connector 106 is driven to slide up and down, thereby causing the monitoring tube 702 to slide up and down. This allows the air quality monitoring height to be adjusted, enabling the device to monitor air quality at different heights as needed, expanding its applicability. Furthermore, the rain cover 105 can shield the structure on and inside the base 101, preventing rain from significantly impacting the gas composition analyzer 901, controller 204, and other structures, thus extending the device's lifespan. Rotating the first rod 103 can rotate the monitoring tube 702 and the solar panel 203. When air quality monitoring is not required, adjusting the angle of the solar panel 203 allows it to receive sunlight to the maximum extent. When air quality monitoring is needed, rotating the monitoring tube 702 in the direction of airflow allows air to enter and quickly flow out, enabling air quality monitoring. The rapid airflow also prevents air from remaining in the monitoring tube 702 and affecting subsequent monitoring, thus improving detection accuracy.

[0046] The power generation structure includes a solar panel 203, a plurality of first connecting rods 202 fixed on the connector 106, the first connecting rods 202 being fixedly connected to the solar panel 203, and an energy storage structure including a battery 201 installed in the base 101, the battery 201 corresponding to the solar panel 203, and a controller 204 fixed on the base 101.

[0047] Specifically, solar panels 203 generate electricity, which is stored in a battery 201. The battery 201 then powers the controller 204, the first motor 301, the second motor 705, the gas composition analyzer 901, and sensors. The controller 204 controls the operation of the first motor 301, the second motor 705, the gas composition analyzer 901, and the sensors, and receives data signals from the sensors and the gas composition analyzer 901. After processing the data, the controller 204 wirelessly transmits the data to the monitoring center via its wireless data module, thereby enabling the monitoring of air pollution.

[0048] The drive structure includes: a first motor 301, which is fixed inside the base 101; a first rotating shaft 302 is fixed to the output end of the first motor 301; a first sliding groove 305 is provided inside the first rod 103; a second sliding groove 306 is provided inside the second rod 104; the first sliding groove 305 corresponds to the second rod 104; a screw 303 is rotatably fitted inside the first sliding groove 305; the screw 303 corresponds to the second sliding groove 306; the screw 303 is fixedly connected to the first rotating shaft 302; a nut 304 is fixed inside the second sliding groove 306; and a hydraulic oil tank 401, which is fixed to the base 101; a hydraulic oil pump 402 is fixed to one side of the hydraulic oil tank 401; and the oil inlet of the hydraulic oil pump 402 is connected to the hydraulic oil tank 401.

[0049] Specifically, when it is necessary to rotate the monitoring cylinder 702, the first motor 301 is started, which drives the screw 303 to rotate. The screw 303 engages with the nut 304. At this time, the first rod 103 is not fixed, so the screw 303 drives the nut 304 to rotate synchronously, thereby driving the second rod 104 to rotate, thus adjusting the angle of the monitoring cylinder 702. When it is necessary to adjust the height of the monitoring cylinder 702, the first locking block 503 locks the first rod 103, thereby fixing the position of the first rod 103, and then the first motor 301 is started. The first motor 301 drives the first rotating shaft 302 to rotate, which in turn drives the screw 303 to rotate. This causes the screw 303 to engage with the nut 304. Since the position of the first rod 103 is fixed, it limits the second rod 104, preventing it from rotating with the screw 303. This allows the second rod 104 to slide up and down under the action of the screw, thus enabling height adjustment. This allows the device to monitor air quality at different heights, expanding its monitoring range, making it more flexible to use, and ensuring monitoring accuracy.

[0050] The locking structure includes: a first locking frame 501, which is fixed on the base 101 and located around the first rod 103. A first oil chamber 502 is provided inside the first locking frame 501. A first oil inlet pipe 505 is installed between the first oil chamber 502 and the oil outlet of the hydraulic oil pump 402. Multiple first locking blocks 503 are slidably fitted inside the first oil chamber 502. The first locking blocks 503 are in contact with the first rod 103. A first elastic telescopic rod 504 is fixed between the first locking blocks 503 and the first locking frame 501. A first oil outlet pipe 506 is installed between the first oil chamber 502 and the hydraulic oil tank 401. A first electric valve is installed on the first oil outlet pipe 506. Electric valves are installed on the first oil inlet pipe 505, the second oil inlet pipe 605, and the third oil inlet pipe 904.

[0051] Specifically, the first locking block 503 locks and fixes the first rod 103. When it is necessary to fix the first rod 103, the hydraulic oil pump 402 is started to draw out hydraulic oil and send it into the first oil chamber 502. The hydraulic oil pushes the first locking block 503 to slide, so that the first locking block 503 comes into contact with the first rod 103, which can achieve a good locking effect on the first rod 103 and prevent the first rod 103 from moving when adjusting up and down. When it is necessary to rotate the first rod 103, the first electric valve is opened to control the flow of hydraulic oil, which can release the first rod 103 and drive the first rod 103 to rotate synchronously, so as to realize the rotation adjustment of the monitoring cylinder 702.

[0052] The locking structure also includes: a second locking frame 601, which is fixed inside the base 101 and located around the first rotating shaft 302. A second oil chamber 602 is provided inside the second locking frame 601. Multiple second locking blocks 603 are slidably fitted inside the second oil chamber 602. A second elastic telescopic rod 604 is fixed between the second locking blocks 603 and the second locking frame 601. A second oil inlet pipe 605 is installed between the second oil chamber 602 and the oil outlet of the hydraulic oil pump 402. A second oil outlet pipe 606 is installed between the second oil chamber 602 and the hydraulic oil tank 401. A second electric valve is installed on the second oil outlet pipe 606.

[0053] Specifically, after the position of the monitoring cylinder 702 is adjusted, the monitoring cylinder 702 needs to be fixed. The hydraulic oil pump 402 is started, and hydraulic oil is drawn out and sent into the second oil chamber 602. Then, the second locking block 603 is pushed, so that the second locking block 603 comes into contact with the first rotating shaft 302, thereby locking the first rotating shaft 302 and preventing the screw 303 from rotating.

[0054] The air quality monitoring structure includes: a monitoring cylinder 702, with multiple second connecting rods 701 fixed on the connector 106, the second connecting rods 701 being fixedly connected to the monitoring cylinder 702, the monitoring cylinder 702 corresponding to the hydraulic oil pump 402 and the hydraulic oil tank 401, both ends of the monitoring cylinder 702 being equipped with a fixed filter plate 703 and a rotating filter plate 704, the fixed filter plate 703 being fixedly connected to the monitoring cylinder 702, and the rotating filter plate 704 being rotatably connected to the monitoring cylinder 702; a second motor 705 is fixed on one of the fixed filter plates 703, the output end of the second motor 705 is fixed with a second rotating shaft 706, the second rotating shaft 706 being rotatably connected to the fixed filter plate 703, a damping block 707 is fixed on the periphery of the second rotating shaft 706, the damping block 707 corresponding to the rotating filter plate 704, and multiple fan blades 708 are fixed on the second rotating shaft 706.

[0055] Specifically, external air enters directly into the monitoring cylinder 702, is detected, and then flows out. Rotating the rotating filter plate 704 seals the monitoring cylinder 702, allowing it to not only detect air quality but also assist in sampling. When auxiliary sampling is needed, the second motor 705 is activated, driving the second rotating shaft 706 to rotate. This rotation misaligns the filter holes on the fixed filter plate 703 with those on the rotating filter plate 704, achieving a better sealing effect. Sampling is then performed through the monitoring cylinder 702. Furthermore, during airflow, larger impurities in the external air are blocked by the fixed filter plate 703 and the rotating filter plate 704, resulting in a better filtration effect and preventing larger impurities from directly entering the monitoring cylinder 702 and damaging its internal components.

[0056] The air quality monitoring structure also includes: a temperature and humidity sensor 801, a pressure sensor 802, and an air quality sensor 803; wherein the temperature and humidity sensor 801, the pressure sensor 802, and the air quality sensor 803 are all fixed inside the monitoring cylinder 702, and the temperature and humidity sensor 801, the pressure sensor 802, and the air quality sensor 803 are located between two rotating filter plates 704.

[0057] Specifically, the air quality can be initially detected by the temperature and humidity sensor 801, the air pressure sensor 802, and the air quality sensor 803. Furthermore, the air inflow and outflow can be controlled by rotating the rotating filter plate 704, thereby improving the flexibility of the device and expanding its applicable range.

[0058] The wind direction detection structure includes: a wind vane 804, which is rotatably fitted to the top of a connector 106. A torque sensor 805 is installed between the wind vane 804 and the connector 106. The torque sensor 805 corresponds to the first motor 301. The monitoring cylinder 702 is parallel to the wind vane 804.

[0059] Specifically, the external airflow causes the wind vane 804 to rotate, ensuring that the wind vane 804 always points in the direction of the airflow. The rotation angle of the wind vane 804 can be monitored by the torque sensor 805, and the position of the monitoring tube 702 can be adjusted according to the rotation angle of the wind vane 804, so that the monitoring tube 702 is always parallel to the wind vane 804, thus ensuring the monitoring effect of the atmosphere. When the external wind speed is low, the second motor 705 is started, which drives the fan blade 708 to rotate, thereby accelerating the airflow and ensuring the quality of air monitoring.

[0060] The air composition detection structure includes: a gas composition analyzer 901, which is fixed on a base 101. An air inlet pipe 902 is installed at the air inlet end of the gas composition analyzer 901. A sleeve 903 is installed inside the support rod 102, and the air inlet pipe 902 is installed inside the sleeve 903. The air inlet pipe 902 is connected to a monitoring cylinder 702. A third oil inlet pipe 904 and a third oil outlet pipe 905 are installed inside the sleeve 903. The third oil inlet pipe 904 is connected to the oil outlet of a hydraulic oil pump 402. The third oil outlet pipe 905 is connected to the hydraulic oil tank 401, and a third electric valve is installed on the third oil outlet pipe 905; wherein, the monitoring cylinder 702 is equipped with a third locking block 906, and a third oil chamber 907 is opened in the monitoring cylinder 702, the third oil chamber 907 corresponds to the third locking block 906, the third oil chamber 907 is connected to the third oil outlet pipe 905 and the third oil inlet pipe 904, the third locking block 906 corresponds to the rotating filter plate 704, and an angle sensor is installed on the rotating filter plate 704.

[0061] Specifically, the gas composition analyzer 901 can detect the specific components of the air, eliminating the need for manual sampling and laboratory testing, thus improving the working efficiency of the device. Furthermore, the air inlet pipe 902 can be used for gas transportation. By introducing hydraulic oil into the third oil chamber 907, the third locking block 906 can be squeezed, thereby locking the rotating filter plate 704 and achieving a better sealing effect. At this time, the air in the monitoring cylinder 702 can be directly extracted for testing, thus ensuring the accuracy of air pollution detection.

[0062] Workflow: When the monitoring cylinder 702 needs to rotate, the first motor 301 is started, which drives the screw 303 to rotate. The screw 303 engages with the nut 304. At this time, the first rod 103 is not fixed, so the screw 303 drives the nut 304 to rotate synchronously, thereby driving the second rod 104 to rotate, thus adjusting the angle of the monitoring cylinder 702. When the height of the monitoring cylinder 702 needs to be adjusted vertically, the first locking block 503 locks the first rod 103, thus fixing its position. Then, the first motor 301 is started, which drives the first rotating shaft 302 to rotate, and the first rotating shaft 302 drives the screw 303 to rotate. The screw 303 engages with the nut 304. Since the position of the first rod 103 is fixed, it limits the movement of the second rod 104, preventing the second rod 104 from rotating with the screw 303. This allows the second rod 104 to slide up and down under the action of the screw thread, thus achieving height adjustment. This enables the device to monitor air quality at different heights. When it is necessary to fix the first rod 103, the hydraulic pump 402 is activated, drawing hydraulic oil into the first oil chamber 502. The hydraulic oil pushes the first locking block 503 to slide, bringing it into contact with the first rod 103 and effectively locking it, preventing the first rod from rotating. When adjusting the position of the first rod 103, the first electric valve is opened to control the flow of hydraulic oil, thereby releasing the first rod 103 and causing it to rotate synchronously. After the position of the monitoring cylinder 702 is adjusted, it needs to be fixed. The hydraulic oil pump 402 is started to draw hydraulic oil into the second oil chamber 602, which then pushes the second locking block 603, causing it to contact the first rotating shaft 302 and lock it, preventing the screw 303 from rotating. At this point, monitoring can begin. External air enters the monitoring cylinder 702 directly, is detected, and then flows out. The adjustment is then performed by rotating the cylinder. The moving filter plate 704 seals the monitoring cylinder 702, allowing it to function not only for air quality monitoring but also for auxiliary sampling. When auxiliary sampling is needed, the second motor 705 is activated, driving the second rotating shaft 706 to rotate. This rotation misaligns the filter holes on the fixed filter plate 703 with those on the rotating filter plate 704, achieving a better seal. Sampling is then performed through the monitoring cylinder 702. Furthermore, during airflow, larger impurities in the outside air are blocked by the fixed filter plate 703 and the rotating filter plate 704, resulting in effective filtration. The external airflow also causes the wind vane 804 to rotate.This ensures that the wind vane 804 always points in the direction of airflow. The torque sensor 805 monitors the rotation angle of the wind vane 804, allowing adjustment of the monitoring cylinder 702 based on this angle. Finally, the gas composition analyzer 901 can detect the specific composition of the air, eliminating the need for manual sampling and laboratory testing, thus improving the device's efficiency.
