Description

Technical Field

[0001] This utility model relates to the field of sampling drone technology, specifically a low-altitude environmental monitoring drone for sampling atmospheric pollutants. Background Technology

[0002] Air pollution monitoring is a crucial step in assessing environmental quality and formulating pollution control strategies. With rapid industrialization and urbanization, the sources of air pollutants are becoming increasingly complex, highlighting the limitations of traditional ground-based monitoring methods. This has spurred the innovative development of low-altitude environmental monitoring technologies. Traditional air pollution monitoring primarily relies on fixed ground-based monitoring stations and manual sampling. While ground-based monitoring stations can achieve long-term continuous monitoring, they suffer from insufficient spatial coverage, making it difficult to capture dynamic changes in pollution hotspots. Manual sampling, on the other hand, is inefficient, costly, and limited by terrain and sampling conditions, making it difficult to conduct sampling in complex environments such as mountainous areas and densely populated urban areas.

[0003] Traditional ground-based monitoring stations have fixed layouts and large spacing, making it difficult to cover the microscopic areas surrounding pollution sources. For example, in areas with severe localized pollution, such as chemical industrial parks and main traffic arteries, ground-based monitoring stations cannot accurately pinpoint pollutant concentration peaks, resulting in monitoring data that does not accurately reflect the pollution situation. Manual sampling requires personnel to carry equipment to the site, posing safety risks and extremely low sampling efficiency in hazardous areas (such as chemical plant leak sites) or complex terrain (such as mountains and swamps). Therefore, there is a need to design a low-altitude environmental monitoring drone for sampling atmospheric pollutants. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] Example 1:

[0023] Addressing the current problems of inconvenient sampling bag fixing and sealing, and difficulty in controlling the opening and closing of the sampling bag collection port, this utility model provides a preferred embodiment of a low-altitude environmental monitoring drone for atmospheric pollutant sampling, for example... Figure 1-4The image shows a low-altitude environmental monitoring drone for sampling air pollutants, comprising a drone body 1, four sets of flight arms 2 fixedly mounted on the outer wall of the drone body 1, located at the four corners in a symmetrical arrangement, a rotating pointer blade 3 fixedly mounted on the upper part of the flight arms 2 via mounting columns, a camera detection head 4 fixedly mounted on the bottom of the drone body 1, and two sets of mounting support legs 5 fixedly mounted on the bottom of the drone body 1 in an arch shape; a sampling component 6, disposed between the mounting support legs 5 and below the drone body 1; the sampling component 6 includes: a fixed sampling part 61, disposed below and between the mounting support legs 5; and a collection fixed part 62, disposed between the mounting support legs 5, and above and outside the fixed sampling part 61.

[0024] The fixed sampling part 61 includes: a fixed base frame 611, which is fixedly installed on the bottom of the mounting support column leg 5, and there are two sets of fixed base frames 611; an anti-slip pad 612 is fixedly installed on the bottom of the fixed base frame 611, and a sampling installation frame 613 is provided on the top of the fixed base frame 611, and the sampling installation frame 613 is fixedly installed on the bottom of the UAV body 1 through a connecting plate.

[0025] A sampling bag 614 is fixedly installed on the bottom of the inner wall of the sampling installation frame 613. A collection port 615 is opened at the front of the sampling bag 614. A sampling extension tube 616 is connected to the rear surface of the sampling bag 614. A sealing ring cap 617 is fitted on the outer wall of the sampling extension tube 616.

[0026] Furthermore, this embodiment is equipped with a drone body 1, four sets of flight arms 2 and rotating pointer blades 3, which can quickly fly to complex low-altitude areas. Compared with manual sampling, the efficiency is improved and dynamic data on the distribution of atmospheric pollutants can be obtained in a timely manner. Then, the sampling bag 614, together with the collection port 615 and the sampling extension tube 616, forms a sealed sampling space, and the sealing cap 617 ensures zero gas leakage.

[0027] Example 2:

[0028] Please see Figures 1-4 Furthermore, based on Embodiment 1, the following is obtained: the collection and fixing part 62 includes: a connecting C-shaped plate frame 621, which is fixedly installed on the front surface of the sampling installation frame 613; the outer wall of the connecting C-shaped plate frame 621 is provided with a lifting sliding hole 622, and the bottom of the connecting C-shaped plate frame 621 is fixedly installed with an installation shell 623, and the bottom of the inner wall of the installation shell 623 is fixedly installed with a small motor 624.

[0029] The output end of the small motor 624 is provided with an adjusting rotating rod 625, which extends to the bottom of the connecting plate and is threaded. The outer wall of the adjusting rotating rod 625 is movably fitted with a T-shaped sliding plate 626, which extends to the inside of the lifting sliding hole 622 for sliding connection.

[0030] A magnetic clamp 627 is fixedly installed on the outer surface of the T-shaped sliding plate 626, and the magnetic clamp 627 is positioned above the sampling bag 614. A magnetic clamp 628 is provided below the magnetic clamp 627, and the magnetic clamp 628 is fixedly installed on the outer wall of the connecting C-shaped plate frame 621.

[0031] The magnetic clamp 628 is positioned below the sampling bag 614, and the magnetic clamp 628 is attracted to the magnetic clamp plate 627.

[0032] Furthermore, this embodiment uses a small motor 624 to drive the adjusting rotating rod 625, which precisely controls the magnetic clamping plate 627 and the magnetic clamping holder 628 to clamp the sampling bag 614, improving the sealing effect, avoiding external interference to the sample during flight, and effectively ensuring the reliability of the monitoring data.

[0033] In operation, the operator first performs a pre-flight check and parameter settings on the main body 1 of the drone to ensure that components such as the flight arms 2 and rotating pointer blades 3 are functioning properly. The drone can then perform sampling tasks. The operator sends a command through the ground control terminal to start the main body 1. The rotating pointer blades 3 on the four flight arms 2 rotate at high speed under the drive of motors, generating lift to allow the drone to take off smoothly. Simultaneously, the camera detection head 4 at the bottom of the main body 1 starts, capturing real-time images of the environment below and transmitting the images to the ground control terminal, allowing the operator to observe the flight path and surrounding environment. The arched support legs 5 provide stable support during takeoff and landing, while the anti-slip pads 612 at the bottom increase friction with the ground, preventing the drone from slipping. The drone cruises in the low-altitude area along a preset route, searching for suitable sampling points.

[0034] Next, when the drone flies over the target sampling point, the operator sends a command through the ground control terminal to activate the relevant components of the sampling assembly 6. The small motor 624 inside the mounting housing 623 starts working, and the output of the small motor 624 drives the adjusting rotating rod 625 to rotate. Since the outer wall of the adjusting rotating rod 625 is threaded, and the T-shaped sliding plate 626 is fitted on its outer wall and slidably connected to the lifting sliding hole 622, the T-shaped sliding plate 626 moves up and down within the lifting sliding hole 622 as the adjusting rotating rod 625 rotates. In the initial state, the operator controls the T-shaped sliding plate 626 to move upward, so that the magnetic clamp 627 separates from the magnetic clamp 628, preparing for the subsequent gas collection from the sampling bag 614.

[0035] Furthermore, after preparation, atmospheric pollutants enter the sampling bag 614 through the collection port 615 at the front of the bag. During the continuous flight of the drone, the airflow generated by the drone's flight and the airflow itself continuously draw surrounding air into the sampling bag 614, thus collecting atmospheric pollutants. The sampling extension tube 616 is used to connect the sampling bag 614 to any subsequent possible detection equipment or gas transmission pipeline, and the sealing cap 617 on the outer wall ensures the airtightness of the connection, preventing leakage of the collected gas sample.

[0036] Once the preset sampling time is reached or the sampling bag 614 has collected enough gas sample, the operator sends another command through the ground control terminal to cause the small motor 624 to rotate in the opposite direction, adjusting the rotating rod 625 and driving the T-shaped sliding plate 626 downward. As the T-shaped sliding plate 626 moves downward, the magnetic clamp 627 gradually approaches the magnetic clamp 628, and finally the two attract each other, clamping the sampling bag 614 from both the top and bottom, sealing the collection port 615, preventing the gas sample from escaping, and completing the fixation of the gas sample inside the sampling bag 614.

[0037] After sampling is completed, the drone automatically returns to base according to a preset program. Once the drone lands on the ground, operators can remove sampling bag 614 and send it to the laboratory for subsequent analysis and testing of air pollutant components. Simultaneously, the drone can be inspected and maintained to prepare for the next sampling mission.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
