[0002] Stratified sampling equipment is a specialized tool used to collect samples from different depths or layers. It is widely used in fields such as geological exploration, environmental monitoring, marine research, and agricultural soil analysis. Stratified sampling equipment for high-altitude atmospheric environment management is a specialized tool used to collect atmospheric components at different altitudes. It is mainly used to monitor the vertical distribution patterns of pollutants, which can help study atmospheric diffusion mechanisms and provide scientific basis for haze control, climate change research, and air quality assessment.

[0003] Traditional stratified sampling equipment for high-altitude atmospheric environment management is easily damaged during takeoff and landing in special circumstances such as birds or tree branches. Furthermore, the maintenance or repair process for traditional stratified sampling equipment for high-altitude atmospheric environment management is relatively cumbersome, affecting the maintenance efficiency of staff.

[0004] Therefore, those skilled in the art have provided a stratified sampling device for high-altitude atmospheric environment management to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stratified sampling device for high-altitude atmospheric environment management. The sampling box can be quickly fixed and disassembled by using a snap-fit ​​plate and handle in the ejection mechanism. Furthermore, the snap-fit ​​plate and connecting plate, together with the sampling box, allow the internal piston to draw external air along the sampling cylinder, effectively improving the detection efficiency of the device. Subsequently, the gas can be detected by the sampling detector.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

The sampling disassembly mechanism includes a top plate fixedly connected to the lower surface of the drone body, a chassis fixedly connected to the lower surface of the top plate, a bottom plate fixedly connected to the lower surface of the chassis, a dual-axis motor fixedly connected to the middle of the rear end of the upper surface of the bottom plate, a gear fixedly connected to the output end of the dual-axis motor, a rack rotatably connected to the outer wall of the gear, a connecting frame fixedly connected to the front end of the rack near the middle, a connecting rod rotatably connected to the outer wall of the front end of the rack, and a door panel rotatably connected to the end of the connecting rod away from the rack.

[0008] The upper surface of the connecting frame is provided with a push-out mechanism. The push-out mechanism includes a sampling box located in the middle of the upper surface of the connecting frame. A connecting plate is fixedly connected to the rear outer wall of the sampling box.

[0018] Furthermore, two snap-fit ​​holes are provided on both outer walls of the connecting plate, the snap-fit ​​post is snapped into the snap-fit ​​hole, one end of the spring is fixedly connected to the limiting ring, and the end of the spring away from the limiting ring is fixedly connected to the snap-fit ​​plate.

[0019] The above technical solution uses a limit ring to restrict the movement distance of the handle.

[0020] Furthermore, the movable column is fixedly connected to the sampling cylinder and the connecting plate, and the piston slides on the inner wall of the sampling cylinder;

[0021] Using the above technical solution, gas can be extracted by sliding the piston on the inner wall of the sampling cylinder.

[0022] Furthermore, support arms are fixedly connected to the front and rear ends of the outer walls on both sides of the drone body, and propellers are provided on the upper surface of the support arms away from the drone body.

[0044] The sampling box 303 can be quickly fixed and disassembled by using the snap-fit ​​plate 302 in the ejection mechanism 3 in conjunction with the handle 301. Furthermore, the snap-fit ​​plate 302 and the connecting plate 3012, together with the sampling box 303, allow the internal piston 3011 to draw external air along the sampling cylinder 307, which can effectively improve the detection efficiency of the equipment. Subsequently, the gas can be detected by the sampling detector 308.

[0045] Reference Figure 3 , Figure 4 and Figure 5The rack 4011 has multiple toothed grooves 408 at its rear end on its upper surface. The gear 406 meshes with the toothed grooves 408. A limit frame 4013 is provided on one side of the rack 4011 near the middle. The gear 406 is driven to rotate by the dual-shaft motor 407. The rack 4011 can move forward or backward by engaging with the gear 406 through the toothed grooves 408. At the same time, the sampling box 303 can be moved by the connecting frame 4010. The rack 4011 will drive the connecting rod 409 to open the door panel 405 forward along the slide groove 7. When it opens, the sampling box 303 will be pushed out of the base plate 404, which can effectively improve the sampling efficiency of the equipment and provide protection for the device.

The door panel 405 can be opened by rotating seats 4012. A mounting bracket 309 is fixedly connected to the front end of the inner wall of the sampling cylinder 307. A sampling detector 308 is fixedly connected inside the mounting bracket 309. The sampling detector 308 can detect the extracted gas. The outer walls of both sides of the connecting plate 3012 are opened. There are two snap-fit ​​holes 8, and the snap-fit ​​post 305 is snapped into the snap-fit ​​hole 8. One end of the spring 304 is fixedly connected to the limiting ring 306, and the end of the spring 304 away from the limiting ring 306 is fixedly connected to the snap-fit ​​plate 302. The limiting ring 306 can limit the movement distance of the handle 301. The moving post 3010 passes through the sampling cylinder 307 and is fixedly connected to the connecting plate 3012. The piston 3011 slides on the inner wall of the sampling cylinder 307. Gas can be extracted by the piston 3011 sliding on the inner wall of the sampling cylinder 307.

[0047] Reference Figure 1 , Figure 2 and Figure 8 Support arms 6 are fixedly connected to the front and rear ends of the outer walls on both sides of the drone body 1. A propeller 5 is provided on the upper surface of the support arm 6 away from the drone body 1. A support frame 2 is fixedly connected to the lower end of the outer walls on both sides of the drone body 1. The support frame 2 can provide a certain degree of protection for the entire device.

[0048] Working principle: When the device is needed, first start the drone body 1, so that the propeller 5 on the drone body 1 drives the entire device to take off. After reaching a suitable altitude, start the dual-axis motor 407. The dual-axis motor 407 drives the gear 406 to rotate. When the gear 406 rotates, it drives the rack 4011 under the tooth groove 408 to move. At this time, the rack 4011 pushes the sampling box 303 and the connecting rod 409 to move. The connecting rod 409 causes the door panel 405 to open along the slide groove 7. When it opens, the rack 4011 drives the sampling box 303 to move through the connecting frame 4010. When moving, piston 3011 is restricted by moving column 3010, causing piston 3011 to move along sampling cylinder 307 to extract gas. After extraction, the gas is detected by sampling detector 308. After detection, the device is lowered. When maintenance is required, first pull handle 301. Handle 301 moves locking column 305, and limit ring 306 on handle 301 will squeeze spring 304. Then locking column 305 will separate from connecting plate 3012, and sampling box 303 can be taken out for maintenance. Then, the sampling box 303 can be put back in its original position by the above operation.
