Description

Technical Field

[0001] The present invention relates to the technical field of atmospheric environment monitoring, and specifically to an atmospheric monitoring device based on a multi-rotor unmanned aerial vehicle (UAV). Background Art

[0002] The quality of the atmospheric environment is closely related to our lives. The gas concentration in the atmosphere will greatly affect our quality of life, and the increase in the content of pollutant gases in the atmosphere will even affect our life and health. Therefore, atmospheric environment monitoring work has become particularly important. Most atmospheric environment monitoring uses air quality monitoring vehicles and portable handheld monitoring devices to monitor the atmospheric environment.

[0003] With the development of multi-rotor UAV technology, the atmospheric monitoring equipment in the mid-low altitude has changed from being driven by balloons to being driven by UAVs. Generally, due to the limited take-off weight of UAVs, UAVs can often only carry relatively light instruments to conduct atmospheric monitoring in the air. For this reason, an atmospheric monitoring technology has been developed in which UAVs conduct initial detection operations and sampling operations in the air, and the samples are further detected after the UAVs fly back. In real life, the pollution of the atmospheric environment is often affected by the smoke discharged from industries. Many enterprises, in order to save costs, often only start the smoke-related purification equipment after the monitoring personnel arrive at the factory. This makes it impossible for the inspectors to obtain evidence of the factory's polluted atmosphere. If one wants to use a UAV to drive the monitoring equipment to directly monitor in the smoke, due to the characteristics of the smoke discharged from the factory chimney, which is often high-temperature, high-speed, and opaque, ordinary UAVs cannot stably bring the monitoring equipment into the smoke just discharged from the chimney for sampling and detection operations and ensure that the UAV does not malfunction. This directly hinders the personnel from monitoring the pollution of the atmosphere by industrial emissions of smoke. Summary of the Invention

Driven by the two multi-rotor UAV bodies, the two wire suspension mechanisms jointly lift a set of sampling and monitoring structures above the chimney. Then, the air extraction module performs smoke extraction operations. As the multi-rotor UAV body flies back to the telescopic supporting structure, the air intake detection structure performs detection operations on the extracted smoke. Through the cooperation of the UAV lifting structure, the sampling and monitoring structure, the movable plug-in part, and the air intake detection structure, the present invention uses a method of moving the sampling and monitoring structure with a set of UAV lifting structures to perform conventional high-altitude atmospheric sampling and detection operations.

Specific embodiments

[0031] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0032] Example 1, referring to Figures 1 to 10 As shown, an atmospheric monitoring device based on a multi-rotor unmanned aerial vehicle includes a frame 1, and a total control module is fixedly connected to the frame 1. It further includes:

[0033] Two sets of telescopic loading structures 2 connected to the frame 1;

[0034] Two sets of UAV hoisting structures 3 connected to the telescopic loading structure 2. The UAV hoisting structure 3 includes a multi-rotor UAV body 4 movably connected to the telescopic loading structure 2. A wireless communication module is fixedly installed at the top of the multi-rotor UAV body 4. The multi-rotor UAV body 4 is connected with two sets of wire hoisting mechanisms 5. One set of wire hoisting mechanisms 5 is connected with two sets of communication plugs 6, and the other set of wire hoisting mechanisms 5 is connected with two sets of power supply plugs 7;

[0035] Three sets of sampling and monitoring structures 8 connected to the frame 1. The sampling and monitoring structure 8 includes a placement rack 10 fixedly connected to the frame 1. The placement rack 10 is movably connected with a plurality of inclined racks 11. The inclined rack 11 is fixedly connected with a connecting plate 12. The connecting plate 12 is connected with two sets of docking parts 13. The placement rack 10 is fixedly connected with a plurality of electromagnets 63. The electromagnets 63 are used for magnetically attracting the docking parts 13. One set of docking parts 13 is adapted to the communication plug 6, and the other set of docking parts 13 is adapted to the power supply plug 7. The connecting plate 12 is fixedly connected with a temperature sensor 14, a humidity sensor 15, and an air extraction module 16;

[0036] Two sets of mobile plug-in parts 17 connected to the frame 1. The mobile plug-in part 17 enables the wire hoisting mechanism 5 to perform docking operations with the docking part 13 by driving the movement of the wire hoisting mechanism 5;

[0037] An air intake detection structure 18 connected to the frame 1. The air intake detection structure 18 is movably connected to the air extraction module 16.

[0038] During use, the mobile plug-in part 17 docks the two groups of wire suspension mechanisms 5 under the multi-rotor UAV main body 4 with the two groups of docking parts 13 on the same connecting plate 12. Then, both the communication plug 6 and the power supply plug 7 are docked with the docking part 13. At this time, as the multi-rotor UAV main body 4 takes off, the telescopic support structure 2 performs a contraction operation, and the wire suspension mechanism 5 lifts the docking part 13 to lift a group of connecting plates 12, and the inclined plane frame 11 disengages from the placement frame 10. Then, driven by the connecting plate 12, the temperature sensor 14, the humidity sensor 15, and the air extraction module 16 move in the air together. The temperature sensor 14 and the humidity sensor 15 perform temperature and humidity measurement operations, and the air extraction module 16 performs air sample extraction operations. As the multi-rotor UAV main body 4 flies towards the frame 1, after the inclined plane frame 11 falls onto the placement frame 10, the air suction detection structure 18 is docked with the air extraction module 16 to perform detection operations on the extracted air samples. When it is necessary to sample and detect the smoke discharged from the chimney, the mobile plug-in part 17 respectively docks the two groups of docking parts 13 on the same connecting plate 12 with a group of wire suspension mechanisms 5 of the two multi-rotor UAV main bodies 4. During this period, both the communication plug 6 and the power supply plug 7 are docked with the docking part 13. Driven by the two multi-rotor UAV main bodies 4, the two groups of wire suspension mechanisms 5 jointly lift a group of sampling and monitoring structures 8 to above the chimney. Then, the air extraction module 16 performs smoke extraction operations. As the multi-rotor UAV main body 4 flies back to the telescopic support structure 2, the air suction detection structure 18 performs detection operations on the extracted smoke. Through the cooperation of the UAV lifting structure 3, the sampling and monitoring structure 8, the mobile plug-in part 17, and the air suction detection structure 18, the present invention adopts a method of using a group of UAV lifting structures 3 to move the sampling and monitoring structure 8 to perform conventional high-altitude atmospheric sampling and detection operations. It can also adopt a method of jointly lifting a group of sampling and monitoring structures 8 by two groups of UAV lifting structures 3, so that the two groups of UAV lifting structures 3 fly over from both sides of the chimney, and the sampling and monitoring structure 8 flies through and samples the smoke discharged from the chimney, avoiding the impact of high-temperature and high-speed smoke on the multi-rotor UAV main body 4, reducing the amount of soot attached to the multi-rotor UAV main body 4, and ensuring the safety of the detection operations of the present invention.

[0039] In one case of this embodiment, the telescopic support structure 2 includes two groups of active telescopic frames 19 connected to the frame 1. The active telescopic frame 19 includes a sleeve fixedly connected to the frame 1. A linear drive assembly is installed in the sleeve. The linear drive assembly is connected to a sliding plate slidably connected to the sleeve. The sliding plate of the active telescopic frame 19 is fixedly connected to a support frame 20. The support frame 20 is movably connected to the multi-rotor UAV main body 4. The active telescopic frame 19 drives the support frame 20 to move to prevent the support frame 20 from hindering the movement of the sampling and monitoring structure 8.

[0040] In a case of this embodiment, the wire suspension mechanism 5 includes a hanger 21 movably connected to the multi-rotor UAV body 4. A box body 22 is fixedly installed at the lower end of the hanger 21. The box body 22 is fixedly connected to a double-output shaft motor 23. The output ends of the double-output shaft motor 23 are fixedly connected to wire wheels 24. The two groups of wire wheels 24 connected to the same double-output shaft motor 23 are arranged in the same group of box bodies 22. The wire wheel 24 in a group of box bodies 22 arranged below the multi-rotor UAV body 4 is wound with a power supply cable 25. The power supply cable 25 is electrically connected to a power supply plug 7. The wire wheel 24 in another group of box bodies 22 arranged below the same multi-rotor UAV body 4 is wound with a communication cable 26. The communication cable 26 is communicatively connected to a communication plug 6. Both the power supply cable 25 and the communication cable 26 are fixedly connected to a docking head 27. An annular card slot 28 is formed in the docking head 27. An annular ball groove 29 adapted to the docking portion 13 is formed on the surface of the docking head 27. The double-output shaft motor 23 is used to drive the wire wheel 24 to rotate. The rotating wire wheel 24 is used to wind the power supply cable 25 or the communication cable 26, so as to adjust the height of the docking head 27. The power supply plug 7 is electrically connected to the internal power supply of the multi-rotor UAV body 4 through the power supply cable 25. The communication plug 6 is communicatively connected to the wireless communication module at the top of the multi-rotor UAV body 4 through the communication cable 26. Under normal circumstances, the annular ball groove 29 is connected to the docking portion 13, so that the wire suspension mechanism 5 is docked with the docking portion 13.

[0041] In a case of this embodiment, the docking portion 13 includes a linkage plate 30 fixedly connected to the connecting plate 12. The linkage plate 30 is fixedly connected with two groups of chassis 31. The chassis 31 is fixedly connected with multiple groups of pipe bodies 32. A spring is fixedly connected to the pipe body 32. The spring is fixedly connected with a hemispherical plug 33. The hemispherical plug 33 is fixedly connected with a pressing head 35 through a connecting rod 34. The pressing head 35 is slidably installed in the pipe body 32. The chassis 31 is movably connected with a sealing frame 36. The sealing frame 36 has ferromagnetism. One end of the pipe body 32 away from the chassis 31 is slidably connected with the sealing frame 36. The chassis 31 is fixedly connected with multiple groups of elastic telescopic rods 37. The moving end of the elastic telescopic rod 37 is fixedly connected with the sealing frame 36. A power supply socket 38 is fixedly connected to the chassis 31 in one docking portion 13 on one group of connecting plates 12. A communication socket 39 is fixedly connected to the chassis 31 in the other docking portion 13 on the same group of connecting plates 12. The electromagnet 63 magnetically attracts the sealing frame 36, and the sealing frame 36 presses the elastic telescopic rod 37 so that the sealing frame 36 disengages from the pipe body 32. Then, the docking head 27 is inserted into the chassis 31. The docking head 27 presses the hemispherical plug 33. Then, under the push of the spring on the hemispherical plug 33, the hemispherical plug 33 is stuck into the annular ball groove 29. During this period, the power supply socket 38 is docked with the power supply plug 7, and the communication socket 39 is docked with the communication plug 6. Then, the electromagnet 63 is powered off. Under the push of the elastic telescopic rod 37, the sealing frame 36 seals the pipe body 32, thereby preventing the pressing head 35 from moving. Since the pressing head 35 is fixedly connected with the hemispherical plug 33 through the connecting rod 34, at this time, the end of the hemispherical plug 33 continuously embeds into the annular ball groove 29, thus preventing the hemispherical plug 33 from accidentally disengaging from the annular ball groove 29.

[0042] In a case of this embodiment, the air extraction module 16 includes an air storage tank 40 fixedly connected to the connecting plate 12. Multiple groups of electric telescopic rods 41 are fixedly installed in the air storage tank 40. The moving end of the electric telescopic rod 41 is fixedly connected with a piston plate 42. The piston plate 42 is slidably installed in the air storage tank 40. The air storage tank 40 is fixedly connected with a first control valve 9. The first control valve 9 is movably connected with the air intake detection structure 18. A second control valve 43 is fixedly installed at the bottom of the air storage tank 40. The first control valve 9 is opened, and the electric telescopic rod 41 pulls the piston plate 42, so that external air is drawn into the air storage tank 40. Then, the first control valve 9 is closed. When the air intake detection structure 18 is docked with the first control valve 9, the electric telescopic rod 41 pushes the piston plate 42, so that the air sample stored in the air storage tank 40 is pressed into the air intake detection structure 18.

[0043] In a case of this embodiment, the air intake detection structure 18 includes a detection box 44 fixedly connected to the frame 1. A carbon dioxide content detector 45 is fixedly installed in the detection box 44. A particulate matter detection probe 46 is fixedly installed in the detection box 44. An air inflation pump 47 is fixedly connected to the detection box 44. An air extraction pump 48 is fixedly connected to the detection box 44. A confluence pipe 49 is fixedly connected to the detection box 44. A reversing valve 50 is fixedly connected to the confluence pipe 49. The reversing valve 50 is fixedly connected to three groups of branch pipes 51. A docking pipe 52 that is movably connected to the first control valve 9 is slidably connected to the branch pipe 51. A first active telescopic rod 53 is fixedly connected to the branch pipe 51. A support plate 54 fixedly connected to the docking pipe 52 is fixedly connected to the mobile end of the first active telescopic rod 53. Under normal circumstances, the first active telescopic rod 53 drives the support plate 54 to move. The support plate 54 drives the docking pipe 52 to dock with the first control valve 9. Then the first control valve 9 is opened. With the start of the air extraction pump 48 and the push of the piston plate 42, the atmospheric sample in the gas storage tank 40 sequentially passes through the docking pipe 52, the branch pipe 51, the reversing valve 50, and the confluence pipe 49. Then the carbon dioxide content detector 45 and the particulate matter detection probe 46 perform detection operations. Then the second control valve 43 is opened. The air extraction pump 48 is powered off. The air inflation pump 47 performs an inflation operation, so that air flows into the gas storage tank 40. Then the residue in the gas storage tank 40 is ejected from the second control valve 43 to perform a cleaning operation on the gas storage tank 40.

[0044] Embodiment 2. On the basis of Embodiment 1, refer to Figure 1 and Figure 8 , the mobile plug-in part 17 includes a track frame 55 fixedly connected to the frame 1. Two groups of second active telescopic rods 56 are fixedly connected to the track frame 55.
