[0002] In atmospheric environment monitoring operations, in order to improve the accuracy of atmospheric environment monitoring values, determine atmospheric contents such as ozone residue and atmospheric particulate matter concentration, use lidar including but not limited to atmospheric ozone and pollutant monitoring to detect pollutant values; and improve the level of refined management to provide technical support for the continuous improvement of regional air quality. In order to improve the efficiency of atmospheric environment monitoring and management of different regional layers, the air of different regional layers is generally divided into modules, and the atmospheric samples divided by regions and modules are separated and sampled and isolated through unmanned aerial vehicle-mounted atmospheric samplers to avoid the residual atmospheric pollutants in different regions and altitudes, which affect the accuracy of the data obtained from atmospheric environment monitoring.

[0003] For example, the existing Chinese patent with publication number CN117213932A: A uniform gas collection device for outdoor atmospheric detection, which includes: a drone body, a base is fixed at the bottom by bolts, and air intake channels are distributed at equal angles at the bottom of the base, and a buffer protection mechanism is fixed to the air intake channel and the bottom of the base; it also includes: an air intake guide component, which is arranged at the inner middle position of the base to uniformly guide and collect the gas flowing in the air intake channel; a uniform collection component, which is arranged in the air collection cavity set on the side of the base, and is used synchronously with the air intake guide component to perform independent air collection and storage for atmospheric detection; the uniform gas collection equipment for outdoor atmospheric detection can operate at high altitude, stably collect uniform atmosphere at high altitude in different areas, and collect the collected gas. The atmosphere is classified and stored independently; it adopts the method of UAV-mounted atmospheric sampling, and the supporting sampling mechanism uses the airflow during the flight of the UAV's wings to complete the atmospheric sampling. However, in actual use, the airflow driven by the UAV's wings can complete the atmospheric sampling, but it will also lead to the difficulty of UAV driving control for detailed operations such as flight and steering using the action of airflow, and the sensitivity and accuracy of operation are reduced, making it difficult to fly and perform gas sampling operations; or the existing common UAV-mounted pump body components for air suction and atmospheric sampling operations, which will greatly affect the UAV's mounting load-bearing capacity and maximum mileage.

[0010] Preferably, a damping ring is provided on the bottom edge of the turbine disc, and a limit ring is fixed on the inner concave cavity wall at the bottom of the drone body on the side of the turbine disc; The limiting ring and the damping ring are coaxially distributed and located in the same annular projection plane, and a damping is provided between the limiting ring and the damping ring.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the UAV-mounted atmospheric sampler for green and low-carbon monitoring has a simple structure, utilizes the atmospheric airflow during the conventional flight of the UAV, performs efficient atmospheric sampling operations without affecting the control of the UAV, and does not cause problems such as sampling inaccuracy due to air pressure, thereby improving the efficiency and accuracy of atmospheric sampling. The specific contents are as follows: 1. Through the reserved inner cavity at the bottom of the drone body and the supporting rotatably mounted turbine disc, when performing atmospheric sampling, the impact between the atmospheric airflow and the turbine disc enables the turbine disc to rotate under the action of the airflow. The restriction of the reciprocating thread groove is used to achieve the reciprocating lifting and lowering of the turbine disc when it is rotated by the airflow. The reciprocating deformation impact of the rubber pad on the turbine disc on the elastic air intake pipe is used to realize the air pressure drive of the elastic air intake pipe deformation, and the airflow is driven into the air tank in a pumping manner for storage; Furthermore, by interconnecting the damping ring and the limiting ring, when the locator is positioned due to the magnetic interaction between the bottom permanent magnet and the electromagnetic assembly, the damping ring and the limiting ring damp each other, thereby limiting the rotational movement of the turbine disc caused by the airflow. In addition, the damping ring and the limiting ring form a disconnection barrier to the air guide channel, reducing the airflow turbulence caused by the continuous opening of the air guide channel, which affects the flight state of the drone. Furthermore, the magnetic poles of the electromagnetic assembly change, and the locator and turbine disc are driven upward in reverse by utilizing magnetic action. The upper end of the locator is limited when it contacts the outer wall of the intake assembly due to the damping design, so that when the turbine disc rotates due to the airflow, it will not synchronously drive the locator to rotate, thereby maintaining the state of the turbine disc rotating and reciprocating and lifting under the action of the airflow.

[0017] 2. A gas transfer component is set up. When the electromagnetic assembly drives the positioner and the turbine disk to rise and fall by changing the magnetic poles, the electromagnetic assembly can also drive the limit gear rod to change the height through the corresponding magnetic poles and increase the magnetic strength. The limit gear rod is synchronized with the dual-wheel transmission gear assembly and the bevel gear ring to achieve the rotation and angle change of the transfer tube. Under the alignment of the transfer tube and the guide tube, the atmospheric sampling of different gas storage tanks and the classified storage of atmospheric samples are completed.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1-8 The present invention provides a technical solution: an unmanned aerial vehicle (UAV) atmospheric sampler for green and low-carbon monitoring, comprising a UAV body 1 and a detachably mounted gas storage tank 2 on its outer side; and further comprising: an air guide channel 3, which is arranged through the UAV body 1, and an air intake assembly 4 is fixed to the middle of the concave cavity at the bottom of the UAV body 1, and an elastic air intake pipe 5 for pressure-intake is provided on the top of the air intake assembly 4. The elastic air intake pipe 5 for pressure-intake is repeatedly compressed and expanded under the action of pressure and its own elastic force by applying pressure by external force, and the gas can be reduced to a pressurized pumping form during compression, resulting in the inside of the air intake assembly 4 and circulating inside the air intake assembly 4, thereby realizing the pressure pumping output of the atmospheric sampling sample and realizing the pump The pumping type of atmospheric sampling gas delivery is stable and efficient compared with the sampling method only through atmospheric airflow and airflow driven by drones, and will not cause the external air pressure of natural gas sampling to push the backflow and discharge due to the air pressure caused by the flight of drones and the action of atmospheric airflow, so that the preservation of atmospheric samples is more stable. It is set as a "T"-shaped structure with an inner hollow through the air intake component 4, wherein the air intake component 4 is connected with the interior of the gas storage tank 2 through the gas transfer component 8 and the guide pipe 9; and the air intake component 4 and the elastic air intake pipe 5 on the outer side of its upper end are connected, and the gas pumped inside the air intake component 4 is introduced into the gas storage tank 2 for storage by using the gas transfer component 8 and the guide pipe 9 for connection.

[0022] At the same time, in the present technical solution, a positioner 6 is provided in the middle part of the outer side of the air intake component 4, and a turbine disc 7 is threadedly installed on the outer side of the positioner 6. The turbine disc 7 is driven by airflow and connected with a reciprocating thread to realize the reciprocating lifting and lowering control of the pressure intake of the elastic air intake pipe 5 under the action of wind energy; the structure of using wind energy to drive the turbine disc 7 to rotate and reciprocate in the present technical solution is as follows: the inner wall of the positioner 6 and the outer wall of the middle section of the air intake component 4 are vertically slidingly connected with each other, and the outer wall of the positioner 6 is provided with a reciprocating thread groove, and the positioner 6 and the turbine disc 7 are reciprocatingly threaded. A rubber pad for deforming and pressurizing the elastic air intake pipe 5 is provided on the top of the turbine disc 7; a permanent magnet is provided at the annular bottom of the positioner 6, and the positioning of the positioner 6 at the height of the outer side of the air intake component 4 is controlled by the magnetic force on the gas adapter component 8.

[0023] In the above scheme, the magnetic change device on the gas transfer component 8 can be used to drive the positioner 6 and the turbine disk 7 thereon to rise and fall under the action of the change of magnetism and magnetic poles. When the positioner 6 and the turbine disk 7 thereon are driven close to the upper end of the air intake component 4, due to the magnetic effect, the damping structure provided on the upper end of the positioner 6 is in tight contact with the outer wall of the air intake component 4, so as to achieve the limit of the positioner 6 under the push of damping and external force, and the turbine disk 7 is driven by the airflow during the downward flight of the drone. When the turbine disk 7 rotates under the drive of the airflow, the turbine disk 7 and the positioner 6 are connected by the reciprocating thread groove, so that the turbine disk 7 moves alone, and its reciprocating lifting and lowering is used to compress the elastic air intake pipe 5 on the air intake component 4 through external force, so as to achieve the pumping-type airflow conveying effect of the elastic air intake pipe 5.

[0024] At the same time, in the above technical solution, a damping ring 701 is provided at the bottom edge of the turbine disc 7, and a limiting ring 702 is fixed on the inner concave wall of the bottom of the drone body 1 on the side of the turbine disc 7; wherein the limiting ring 702 and the damping ring 701 are coaxially distributed and located in the same annular projection plane, and a damping arrangement is provided between the limiting ring 702 and the damping ring 701. By utilizing the interaction between the damping ring 701 and the limiting ring 702, when the turbine disc 7 and the positioner 6 move downward due to magnetism and the damping ring 701 and the limiting ring 702 come into contact, the damping and adhesion between the two close the inner concave cavity at the bottom of the drone body 1 where the lower end of the air guide channel 3 is located, the gas channel is separated, and the airflow cannot circulate, thereby avoiding the problems of airflow obstruction and noise caused by airflow impact during normal driving of the drone body 1 due to the airflow circulation and backflow in the air guide channel 3 and the inner concave cavity at the bottom of the drone body 1. At the same time, when the limiting ring 702 and the damping ring 701 are separated, as shown Figure 5 and Figure 6As shown, at this time, the concave cavity space at the bottom of the drone body 1 where the elastic air intake pipe 5 is located forms a gas reflux space composed of the inner wall of the concave cavity at the bottom of the drone body 1 and the turbine disk 7. At this time, when the drone is traveling and the atmosphere flows through the concave cavity at the bottom of the drone body 1 and the air guide channel 3, it will flow back in the gas reflux space due to the airflow dynamics, so that the gas in this atmospheric space can be stirred and mixed, and when it is introduced into the air intake component 4 for subsequent gas storage, the collected atmospheric data samples are more accurate.

[0025] Example 2: Based on Example 1, the present invention is as follows Figures 9-13 As shown, in order to improve the efficiency of atmospheric sampling, multiple detachable gas storage tanks 2 and their corresponding components are provided, so that when performing modular sampling of the atmospheric space environment, atmospheric samples in different regional environments can be classified and stored, and a single sampling can collect multiple types of samples as required. At the same time, in order to use the gas adapter component 8 and the guide tube 9 to classify and store the atmospheric samples sucked in by the intake assembly 4 due to the pumping method into different gas storage tanks 2, a gas adapter is provided in the gas adapter component 8, so that the atmospheric samples stored in different gas storage tanks 2 are easy to operate and will not cause the mixing of atmospheric samples in different areas. The specific contents are as follows: First, the gas tanks 2 are evenly spaced at equal intervals on the outside of the drone body 1, and the number of gas tanks 2 and the guide tubes 9 are equal and one-to-one corresponding; the sealing plug at the bottom of the gas tank 2 and the guide tube 9 are inserted and disassembled by penetration, and the drone body 1 is provided with an elastic positioning plate 202 for vertical pressure limiting of the gas tank 2, and an elastic diaphragm 201 is provided on the outside of the gas tank 2; the sealing plug and the guide tube 9 are inserted by penetration, which facilitates the installation and disassembly of the gas tank 2, and the elastic positioning plate 202 includes a lifting spring pin and an elastic spring, which can apply downward pressure to the top of the gas tank 2, so that the gas tank 2 will not fall during the sampling process, and the setting of the elastic diaphragm 201 can perform one-way gas flow control. When the gas in the guide tube 9 flows into the gas tank 2, the internal pressure of the gas tank 2 increases, causing the elastic diaphragm 201 is deformed and opened due to the internal pressure, and the impurity gas remaining in the gas storage tank 2 is discharged. After the air intake in the gas storage tank 2 is completed, the elastic diaphragm 201 is reset and blocks the gas outlet of the gas storage tank 2 again to prevent the gas from escaping. The elastic diaphragm 201 is equivalent to a one-way valve setting and can be used as a replacement; and the sealing plug at the bottom of the gas storage tank 2 can seal and control the gas inlet at the bottom of the gas storage tank 2 after the guide tube 9 is pulled out; further, since the gas outlet of the gas storage tank 2 is blocked by the elastic diaphragm 201, when the gas storage tank 2 is not in the air intake state, due to the action of air pressure, the atmospheric sample collected inside the gas storage tank 2 will not be discharged from the guide tube 9. Of course, in order to improve the gas one-way barrier properties of the guide tube 9, a one-way valve structure can be set in the middle section of the guide tube 9, so that the gas sample can only be introduced into the gas storage tank 2 through the guide tube 9 and will not be discharged in the reverse direction.

[0026] At the same time, in the present technical solution, the inner hollow shell of the gas transfer component 8 is fixedly connected to the guide pipe 9 and the air intake component 4 in a through-type manner; at the same time, a gas adapter is also provided in the gas transfer component 8 to control the air intake component 4 and the guide pipe 9 and accurately connect the exhaust operation, and the gas adapter is used to sample the atmosphere under the action of external pressure and store it separately in the gas storage tank 2; the gas adapter includes an electromagnetic component 801 set on the top of the gas transfer component 8, and a limit gear rod 802 installed vertically for sliding inside the gas transfer component 8, and a dual-wheel transmission gear assembly 803 meshed with the side of the limit gear rod 802; the gas adapter also includes a transfer tube 805 for realizing gas transfer between the air intake component 4 and the guide pipe 9, and a bevel gear ring 804 is fixed on the outer wall of the transfer tube 805; wherein the limit gear rod 802 and the dual-wheel transmission gear assembly 803 and the bevel gear ring 804 are fixed on the outer wall of the transfer tube 805 The three gear rings 804 are meshed and connected in sequence, and the transfer tube 805 and the lower end air outlet of the air inlet component 4 are relatively rotatably connected by means of sealed bearings; the upper end of the limit gear rod 802 is magnetically arranged, and the limit gear rod 802 is driven to rise and fall vertically by the magnetic change of the electromagnetic component 801; at the same time, a damping limiter 806 is provided at the through-sliding connection between the internal bracket of the gas transfer component 8 and the limit gear rod 802, and the damping limiter 806 is fitted with the limit gear rod 802, wherein the setting of the damping limiter 806 makes the vertical lifting of the limit gear rod 802 more stable and will not be deviated. At the same time, during the lifting and lowering process of the limit gear rod 802, the damping effect of the damping limiter 806 is utilized to limit the free fall of the limit gear rod 802 due to its own gravity and shock effect, so that the limit gear rod 802 can only be lifted and lowered under the action of magnetism; The above-mentioned scheme is set up so that when collecting atmospheric samples from different areas, the magnetism and magnetic poles of the electromagnetic assembly 801 can be controlled. The control adopts integrated circuit remote control. The electromagnetic assembly 801 generates magnetic poles that attract or repel the upper end of the limit gear rod 802. Through the principle of like poles repelling and unlike poles attracting, as well as the change in the magnetic strength of the electromagnetic assembly 801, the limit gear rod 802 is raised and lowered to different degrees. During this process, the lifting and lowering of the limit gear rod 802 drives the dual-wheel transmission gear assembly 803 to rotate, and the dual-wheel transmission gear assembly 803 drives the bevel gear ring 804 to rotate with the transfer tube 805, so that the transfer tube 805 and the ends of different guide tubes 9 are aligned. The transfer tube 805 and the guide tube 9 are both equipped with sealing rings at both ends, and magnetic rings for magnetic attraction and alignment are also provided therein, so that the alignment of the two is stable, and the atmospheric sample of the air intake assembly 4 can be introduced into the gas storage tank 2 for storage through the transfer tube 805 corresponding to different guide tubes 9.

[0027] Furthermore, in the above scheme, the upper and lower end faces of the electromagnetic component 801 are both provided with iron cores, and the vertical movement and positioning of the locator 6 are driven by the magnetic change of the upper end face of the electromagnetic component 801; therefore, the use of the electromagnetic component 801 can drive the limiting gear rod 802 to rise and fall, and can also drive the locator 6 to rise and fall. Under the action of magnetic repulsion, the locator 6 can directly perform positioning, extrusion and damping positioning with the intake component 4, and when the turbine disk 7 rotates and rises, there will be no synchronous rotation movement trend of the locator 6 and the turbine disk 7.

[0028] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
