Description

Technical Field

[0002] Accurately and quickly locating the sources of air pollution and understanding its main components are essential for effective governance and protection of the environment. This involves public health and environmental protection. Therefore, scientifically and effectively solving the problem of air pollution is one of the important tasks of current and future environmental protection.

[0003] With the rapid development of drone technology, drones can carry various sensors and monitoring equipment and perform efficient and flexible monitoring tasks in the air, covering a large area and obtaining a large amount of atmospheric composition data in a short time. This makes the use of drones to track atmospheric pollution sources one of the effective methods for locating atmospheric pollution sources. When drones perform high-altitude monitoring tasks, the wings of the drones rotate at high speed, thereby accelerating the airflow velocity around the sensors and monitoring equipment carried by the drones. In addition, during the high-speed flight of the drones, the airflow velocity passing through the sensors and monitoring equipment is also accelerated. The high-speed airflow will dilute the gas concentration near the sensor, or the high-speed airflow will produce turbulence and turbulence, making the gas flow on the sensor surface unstable, thereby affecting the accuracy of detecting low-concentration gases and causing inaccurate measurement results. In addition, the high-speed airflow will increase the heat exchange on the sensor surface, causing temperature fluctuations, further affecting the sensitivity and accuracy of the sensor, so a drone with a sniffing wing tracking function is proposed.

DETAILED DESCRIPTION

[0026] In order to make the purpose, features and advantages of the invention of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in combination with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0028] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0029] Reference Figures 1 to 3 An embodiment of the utility model provides a drone with a wing sniffing tracking function, including a drone body 10, a gas monitoring device 20, an airflow buffer device 30 and a camera 40. The gas monitoring device 20, the airflow buffer device 30 and the camera 40 are all arranged on the lower end surface of the drone body 10. The lower end surface of the drone body 10 is provided with a first mounting column 11 and a second mounting column 12, the gas monitoring device 20 is fixed to one end of the airflow buffer device 30, and the airflow buffer device 30 is installed on the drone body 10 through the first mounting column 11. A mounting plate 41 is provided on the second mounting column 12, and the camera 40 is installed on the mounting plate 41. Specifically, the height of the first mounting column 11 is less than the height of the second mounting column 12, and the height of the second mounting column 12 is greater than the sum of the height of the first mounting column 11 and the thickness of the airflow buffer device 30. That is, the airflow buffer device 30 is located between the lower end surface of the drone body 10 and the upper end surface of the mounting plate 41, and there is a gap between the airflow buffer device 30 and the mounting plate 41; the camera 40 is installed on the side of the mounting plate 41 away from the airflow buffer device 30.

[0030] Optionally, the drone with wing-sniffing tracking function also includes a support foot 50, which is arranged on the lower end surface of the drone body 10, and the height of the support foot 50 is greater than the sum of the height of the second mounting column 12, the thickness of the mounting plate 41 and the thickness of the camera 40, so that when the drone body 10 is supported on the ground by the support foot 50, the camera 40 does not contact the ground.

[0031] The thickness of the gas monitoring device 20 is equal to the thickness of the airflow buffer device 30. The gas monitoring device 20 has a detection air inlet 21 and a detection air outlet 25, and the airflow buffer device 30 has a buffer air inlet 33 and a first buffer air outlet 31. The first buffer air outlet 31 of the airflow buffer device 30 is aligned with the detection air inlet 21 of the gas monitoring device 20, so that an airflow channel of the airflow buffer device 30 is connected with the airflow channel of the gas monitoring device 20. When the drone performs high-altitude monitoring tasks, the high-speed airflow passes through the airflow buffer device 30 and reduces the airflow velocity before entering the gas monitoring device 20 for detecting gas components, avoiding the technical problem that the airflow flowing into the gas monitoring device 20 is a high-speed airflow due to the high-speed rotation of the drone wings or the high-speed flight of the drone, thereby affecting the accuracy of gas detection.

[0032] Specifically, the airflow buffer device 30 includes a buffer device shell 32, and the buffer device shell 32 is open at both ends, that is, one end is the buffer air inlet 33, and the other end is the first buffer air outlet 31. The buffer device shell 32 is divided into a gas diversion area, a gas convergence area and a gas buffer area, and the gas diversion area, the gas convergence area and the gas buffer area are located from the buffer air inlet 33 to the first buffer air outlet 31 in sequence.

[0033] The gas diversion area includes a plurality of gas diversion tubes 34 leading to the gas convergence area and a filling block 35 wrapping the gas diversion tube 34. The filling block 35 isolates the buffer air inlet 33 from the gas convergence area, so that the air flowing in from the buffer air inlet 33 can only flow into the gas convergence area through the gas diversion tube 34. The airflow buffer device 30 also has a second buffer air outlet 36, and one end surface of the filling block 35 close to the buffer air inlet 33 is an inclined surface, and the inclined surface is inclined from the buffer air inlet 33 to the second buffer air outlet 36. One end of the gas diversion tube 34 protrudes from the inclined surface and does not protrude outside the buffer air inlet 33. When the high-speed airflow flows into the gas diversion area from the buffer air inlet 33, the high-speed airflow is diverted into two parts, one part flows into the gas convergence area through the gas diversion tube 34, and the other part flows out of the airflow buffer device 30 through the second buffer air outlet 36. The gas diversion area effectively reduces the air flowing into the gas monitoring device 20, laying a foundation for the subsequent gas buffer area to reduce the flow rate of the high-speed airflow.

[0034] The gas convergence area is a cavity surrounded by the inner wall of the buffer device housing 32, the gas convergence area and the gas buffer area, so that the air flowing in from the multiple gas diversion pipes 34 converges in this area, and the converged air flows into the gas buffer area. After the high-speed airflow flows into the gas convergence area through the gas diversion pipes 34, the high-speed airflow is dispersed, and the airflow velocity is initially reduced.

[0035] The gas buffer zone is filled with a gas buffer layer 37, which includes one of sponge, metal foam, porous ceramics, plastic foam, and glass fiber. Isolation nets 38 are provided at both ends of the gas buffer layer 37 to prevent the material in the gas buffer layer 37 from flowing out of the gas buffer zone.

[0036] It should be noted that the principle of the buffer material in the gas buffer layer 37 to reduce the flow rate of the high-speed airflow is as follows: ① The buffer material usually has a porous structure. When the high-speed airflow passes through these porous materials, the airflow is divided into multiple smaller airflow channels. These small channels force the airflow to slow down and distribute evenly, and reduce the kinetic energy of the airflow by increasing the airflow path and contact area; ② When the airflow passes through the buffer material, the internal surface of the material will produce friction resistance to the airflow. This process consumes part of the kinetic energy of the airflow, thereby reducing the speed of the airflow; ③ When the high-speed airflow passes through a complex porous structure, turbulence and eddies will be generated. The formation of turbulence and eddies will further disperse and weaken the kinetic energy of the airflow, thereby reducing the overall airflow speed; ④ The porous structure or serpentine channel in the buffer material will extend the flow path of the airflow. A longer path means that the airflow needs to pass through more obstacles before reaching the sensor, thereby gradually slowing down; ⑤ Some buffer materials, such as sponges or foams, convert part of the kinetic energy of the airflow into heat energy or other forms of energy through the flexibility and energy absorption characteristics of the material itself, thereby further reducing the airflow speed.

[0037] The gas monitoring device 20 includes a monitoring device housing 22, a circuit board 23 disposed in the monitoring device housing 22, and a chip module 24 disposed on the circuit board 23. The chip module 24 is used to detect the composition of the gas. Specifically, the gas reacts with the gas-sensitive material on the chip module 24 to detect the composition of the gas.

[0038] Optionally, a waterproof breathable membrane 26 is provided on both the detection air inlet 21 and the detection air outlet 25, and a protective net 27 is further provided on the detection air outlet 25, and the protective net 27 is provided on the outer side of the waterproof breathable membrane 26. The waterproof breathable membrane 26 prevents moisture and fog from entering the interior of the gas monitoring device 20, and the protective net 27 protects the waterproof breathable membrane 26.

[0039] It should be noted that the buffer air inlet 33 is aligned with the forward direction of the UAV body 10 so that air can flow into the airflow buffer device 30. In addition, when the UAV is in a hovering state, the detection air outlet 25 can also be converted into an air inlet, and air enters the gas monitoring device 20 through the detection air outlet 25.

[0040] The utility model discloses a drone with a wing-sniffing tracking function, and the specific implementation method is as follows: when the drone performs a high-altitude monitoring task, a high-speed airflow flows into the airflow buffer device 30, and is divided into two parts in the gas diversion area, one part flows into the gas convergence area through the gas diversion pipe 34, and the other part flows out of the airflow buffer device 30 through the second buffer outlet 36; the gas converges together in the gas convergence area and enters the gas buffer area, and flows into the gas monitoring device 20 after the flow rate of the high-speed airflow is reduced by the gas buffer layer 37, and the gas components are detected by the chip module 24 in the gas monitoring device 20. The drone with a wing-sniffing tracking function disclosed by the utility model reduces the flow rate of the airflow flowing into the gas monitoring device 20 through the airflow buffer device 30, avoiding the technical problem that the airflow flowing into the gas monitoring device 20 is a high-speed airflow due to the high-speed rotation of the drone wings or the high-speed flight of the drone, thereby affecting the accuracy of the detected gas.

[0041] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
