Description

Technical Field

[0001] The present invention relates to the field of air pollution monitoring equipment, and in particular to an air pollutant monitoring device powered by solar energy. Background Art

[0002] Due to the complexity of the atmospheric environment, identifying the sources of atmospheric pollutants has long been a research challenge. Traditionally, this approach involves collecting samples from pollution sources and conducting offline laboratory analysis. Most gaseous atmospheric pollutants pose significant health risks and may even be carcinogenic. Furthermore, when an environmental pollution incident occurs, emergency monitoring personnel rush to the scene to collect samples, a time-consuming and inefficient process. Due to time differences, this often fails to reflect the true extent of pollutant emissions or leaks. Currently, fixed-point measurements and drone-based sampling are commonly used for sampling and monitoring.

[0003] Publication number CN215116119U discloses an atmospheric pollutant monitoring device comprising a universal wheel, a base, a bracket, a cleaning box, a monitoring box, and a solar panel assembly. The base is mounted on the universal wheel, the bracket is mounted on the base, the cleaning box is mounted on the base, the monitoring box is mounted on the bracket, and the solar panel assembly is mounted on the monitoring box. The monitoring box comprises a monitoring box body, a battery, a monitoring instrument, a ventilator, a warning sound, and a warning light. The monitoring box body is mounted on the bracket.

[0004] Publication number CN113895610A discloses a multi-rotor UAV mobile atmospheric pollutant monitoring system comprising a UAV, a fixture detachably mounted on the bottom of the UAV, a multi-parameter air monitor detachably mounted inside the fixture, a limiter detachably mounted on the rear side of the top of the UAV, and a temperature and humidity meteorological sensor module detachably mounted inside the limiter.

[0005] However, when using fixed-point measurements, due to differences in weather conditions and measurement altitude, the measurement accuracy is poor and the range is small. When using drone measurements, installing a multi-parameter air monitor on the drone will increase the overall weight, resulting in a small measurement range. Summary of the Invention

The output of the digital display control panel 9 is electrically connected to the input of the first cylinder 302. In actual use, after the drone body 4 lands on the monitoring platform 1, the first cylinder 302 drives the positioning push rod 305 to abut and push the annular support frame 502, thereby achieving positioning of the drone body 4.

[0047] The top cover structure 6 includes a rotating rod 601 with an L-shaped profile. One end of the rotating rod 601 is hingedly connected to the monitoring platform 1 via a first hinged seat 604.

The output of the digital display control panel 9 is electrically connected to the input of the first electric telescopic rod 603. Due to this specific structural design, when the push rod of the first electric telescopic rod 603 reaches its maximum travel, the cover 602 is located directly above the monitoring platform 1. This effectively covers the drone body 4 on the monitoring platform 1, shielding it from sunlight and rain, and thus protecting the drone body 4.

[0048] Working principle:

[0049] When in use, the drone body 4 can fly out from the monitoring platform 1, so as to monitor the pollutants in the surrounding three-dimensional atmospheric environment. When sampling, the drone body 4 flies to a certain height and keeps the position still. First, the push rod of the second cylinder 703 reaches the minimum stroke. At this time, the downsampling chamber is connected to the outside through the first vent hole 710, and the air outlet of the first air pump 704 is connected to the upsampling chamber. The first air pump 704 injects the gas of the external air into the upsampling chamber through the vent groove 706, thereby pressurizing the upsampling chamber. The elastic diaphragm 70 2 undergoes elastic deformation, so that the gas in the lower sampling chamber is discharged from the first vent 710 under the pressure of the elastic diaphragm 702. After the gas in the lower sampling chamber is almost completely discharged, the second air pump 705 discharges the gas in the upper sampling chamber, thereby forming a negative pressure in the upper sampling chamber, causing the elastic diaphragm 702 to undergo elastic deformation toward the upper sampling chamber, thereby sucking the gas in the external air into the lower sampling chamber through the first vent 710 for storage. After sampling is completed, the second cylinder 703 drives the first piston 711 to close the first vent 710.

[0050] After the sampling is completed, the drone body 4 flies back to the monitoring platform 1, and the magnetic block 503 and the magnetic ring 102 realize the initial magnetic connection of the drone body 4, which plays a role in windproof and stability. Then the drone positioning component 3 adjusts the position of the drone body 4 on the upper surface of the monitoring platform 1, so that the sampling air hole and the upper end of the second column 810 correspond to each other up and down, and the positioning push rod 305 and the annular support frame 502 are in contact with each other. At the same time, the upper pressure plate 306 can realize the pressure restriction on the upper side of the annular support frame 502, so that when the second column 810 is inserted into the sampling air hole, the drone body 4 can be prevented from having a tendency to move upward, thereby playing a role in pressing the drone body 4. The second electric telescopic rod 808 drives the detection column 801 to move upward, so that the top of the second column 810 is inserted into the sampling air hole. At this time, the third air pump 806 extracts the gas in the detection chamber 802 to form a negative pressure state, which also avoids affecting the detection results. At this time, the second cylinder 703 cooperates to drive the first piston 711, so that the gas in the lower sampling chamber can enter the detection chamber 802 through the first vent 710 ventilation gap 815 and the second vent 811. Then the third cylinder 812 drives the second piston 813 to re-close the second vent 811, and the detection sensor 804 detects the gas in the detection chamber 802. The detection sensor 804 can use a sulfur dioxide sensor, a nitrogen oxide sensor, a volatile organic compound VOC sensor, a carbon monoxide sensor, a hydrogen sulfide sensor, a PM2.5 and PM10 sensor, etc., for detecting atmospheric pollutants. After the detection is completed, the third air pump 806 extracts the gas in the detection chamber 802.
