[0026] Specifically, the fixed plate 2 can fix the telescopic motor 3 to ensure the stability of the telescopic motor 3 during operation. The movement of the moving block 6 can move the multifunctional air quality detection single-chip microcomputer 10 downward. When the moving block 6 moves, it drives the first sliding column 7 to move, thereby causing the first sliding column 7 to slide on the inner wall of the moving plate 8 and drives the moving plate 8 to move downward. During the movement of the moving plate 8, the moving frame 9 is driven to move downward, thereby driving the multifunctional air quality detection single-chip microcomputer 10 to move downward away from the area of ​​the airflow around the rotation disturbance of the drone blades. At the same time, during the process of the moving frame 9 driving the multifunctional air quality detection single-chip microcomputer 10 to move downward, the second sliding column 13 will drive the sliding sheet 12 to slide on the inner wall of the second fixed column 11, thereby limiting the movement of the moving frame 9, and placing the second sliding column 13 so that it will slide out of the inner wall of the second fixed column 11 during the sliding process, thereby preventing the entire detection component from falling from a high altitude.

[0027] Reference Figure 1 and Figure 4 , a first fixing block 14 is fixedly connected to the upper surface of the detection protection box 1, and a lower mounting ring 15 is fixedly connected to the upper surface of the telescopic rod 4;

[0028] Specifically, the first fixing block 14 can connect the lower mounting ring 15 and the detection protection box 1 .

[0029] Reference Figure 1 and Figure 4The lower mounting ring 15 is fixedly connected with a second fixing block 16 inside, and the second fixing block 16 is rotatably connected with a third fixing column 17 inside; the outer wall of the third fixing column 17 is fixedly connected with an upper mounting ring 18, and the upper mounting ring 18 is fixedly connected with an L-shaped plate 19 inside; the outer wall of the L-shaped plate 19 is fixedly connected with a rectangular block 20, and the inner part of the rectangular block 20 is fixedly connected with a rotating column 21; the outer wall of the rotating column 21 is rotatably connected with a pressing plate 23, and the outer wall of the pressing plate 23 is fixedly connected with a spring 22, and one end of the spring 22 is fixedly connected to the outer wall of the L-shaped plate 19; the outer wall of the lower mounting ring 15 is provided with a sliding groove 24, and the outer wall of the pressing plate 23 is slidably connected to the inner wall of the sliding groove 24;

[0030] Specifically, the pressing plate 23 can be moved by the rotating column 21. The pressing plate 23 is pressed and caused to slide on the inner wall of the slide groove 24 opened on the outer wall of the lower mounting ring 15. While pressing the pressing plate 23, the pressing plate 23 will press the spring 22 to contract. During the contraction of the spring 22, the pressing plate 23 rotates on the outer wall of the rotating column 21 fixedly connected to the inside of the rectangular block 20, and the upper mounting ring 18 can be rotated through the second fixed block 16. Rotating the upper mounting ring 18 can cause the upper mounting ring 18 to drive the third fixed column 17 to rotate inside the second fixed block 16.

[0031] Working principle: When the sampling structure is needed, when the drone flies to the designated area and needs to detect the distribution of carbon pollution gas in the area, a start command is sent to the telescopic motor 3 arranged on the outer wall of the fixed plate 2 through the remote control device on the ground. The telescopic motor 3 is started to extend the telescopic rod 4, and then the telescopic rod 4 drives the moving block 6 to slide on the outer wall of the first fixed column 5 fixedly connected to the outer wall of the fixed plate 2. When the moving block 6 moves, it drives the first sliding column 7 to move, and then the first sliding column 7 slides on the inner wall of the moving plate 8 and drives the moving plate 8 to move downward. In the process of the moving plate 8 moving, it drives the moving frame 9 to move downward, and then drives the multiple The multifunctional air quality detection single chip computer 10 moves downward away from the area where the airflow around the drone blades is disturbed by rotation. At the same time, when the moving frame 9 drives the multifunctional air quality detection single chip computer 10 to move downward, the second sliding column 13 drives the sliding piece 12 to slide on the inner wall of the second fixed column 11, which limits the movement of the moving frame 9. The second sliding column 13 will slide out from the inner wall of the second fixed column 11 during the sliding process, thereby avoiding causing the entire detection component to fall from a high altitude, thereby achieving the effect of reducing the impact of the drone blade rotation on the detection during high-altitude detection, which helps to reduce the impact of external interference on gas sampling and improve the sampling accuracy. To ensure accuracy and reliability, when it is necessary to remove it from the drone mounting frame, it is only necessary to press the pressing plate 23 and cause the pressing plate 23 to slide on the inner wall of the slide groove 24 provided on the outer wall of the lower mounting ring 15. While pressing the pressing plate 23, the pressing plate 23 will compress the spring 22 to contract. During the contraction of the spring 22, the pressing plate 23 rotates on the outer wall of the rotating column 21 fixedly connected to the inside of the rectangular block 20. When the pressing plate 23 completely slides out from the inner wall of the slide groove 24, it is only necessary to rotate the upper mounting ring 18 to cause the upper mounting ring 18 to drive the third fixing column 17 to rotate inside the second fixing block 16. At this time, the detection structure can be removed from the drone mounting component. , so as to achieve the effect of quickly completing the disassembly from the drone, thereby speeding up the preparation time of the detection task, making it convenient for the operator to install and disassemble the sampling structure more quickly, and improving the efficiency and flexibility of task execution. The detection structure can not only reduce the impact of the rotation of the drone blades on the detection during high-altitude detection, but also help reduce the impact of external interference on gas sampling and improve the accuracy and reliability of sampling. In addition, it can also achieve the effect of quickly completing the disassembly from the drone, thereby speeding up the preparation time of the detection task, making it convenient for the operator to install and disassemble the sampling structure more quickly, and improving the efficiency and flexibility of task execution.
