Description

Technical Field

[0001] This utility model relates to the field of sampling tube technology, and in particular to a height-adjustable universal gradient sampling tube. Background Technology

[0002] Greenhouse gases refer to gases in the atmosphere that absorb long-wave radiation reflected from the Earth's surface and then re-emit radiation, such as water vapor, carbon dioxide, and most refrigerants. Their effect is to warm the Earth's surface, similar to how a greenhouse traps solar radiation and heats the air inside. This warming effect of greenhouse gases is known as the "greenhouse effect." As environmental changes intensify, it is necessary to separate and collect atmospheric greenhouse gases such as carbon dioxide and methane for subsequent analysis and control. However, existing greenhouse gas sampling methods often involve connecting sampling tubes to fixed locations. Due to temperature variations, greenhouse gases often have different altitudes, leading to concentration deviations in the collected samples and affecting the accuracy of the sampling data. Therefore, this application proposes a height-adjustable omnidirectional gradient sampling tube. Utility Model Content

[0025] like Figure 1 As shown, the present invention proposes a liftable universal gradient sampling tube, including a housing 1 and a sampling mechanism fixed to the top of the housing 1. The sampling mechanism includes a bottom sampling tube 2 fixed to the top of the housing 1. The inner wall of the bottom sampling tube 2 is slidably connected to a telescopic sampling tube 3 through a limiting block 23. The inner wall of the telescopic sampling tube 3 is slidably connected to a top sampling tube 4. The top of the top sampling tube 4 is fixedly connected to a universal sampling head 5. The outer wall of the universal sampling head 5 is provided with multiple sampling holes 6. By setting multiple sampling holes 6 on the outer wall of the universal sampling head 5, the device can extract gas samples at different heights for detection through the sampling holes 6.

[0026] It should be added that, such as Figure 1 , Figure 2 and Figure 4 As shown, the inner walls of the bottom sampling tube 2, the telescopic sampling tube 3, and the top sampling tube 4 are all equipped with gas transmission mechanisms. Each gas transmission mechanism includes multiple multi-dimensional gradient sampling ports 17 fixed to one side of the outer wall of the bottom sampling tube 2, the telescopic sampling tube 3, and the top sampling tube 4. A gas path sampling tube 18 is fixedly connected to one side of the inner wall of each of the multiple multi-dimensional gradient sampling ports 17. A conduction tube 19 is fixedly connected to one end of each gas path sampling tube 18 away from the multi-dimensional gradient sampling ports 17. A vacuum pump 20 is fixedly connected to one side of the outer wall of the conduction tube 19. An outlet tube 20 is fixedly connected to the output end of the vacuum pump 20. 1. The end of the outlet tube 21 away from the air pump 20 is fixedly connected to a split-type gas path pipe 22. Through multiple multi-dimensional gradient sampling ports 17 on the outer wall of the bottom sampling tube 2, the telescopic sampling tube 3, and the top sampling tube 4, air samples at different heights are extracted and detected. The detected samples are transmitted through the gas path sampling tube 18 into the conduction tube 19. The air pump 20 transmits the gas samples to the outlet tube 21 and the split-type gas path pipe 22 for transmission to external detection equipment for detection, making the sample extracted by the device more accurate and allowing for comprehensive sample extraction.

[0027] In addition, such as Figure 2 and Figure 3As shown, a transmission mechanism is provided on one side of the inner bottom end face of the housing 1. The transmission mechanism includes a lifting controller 7 fixed to the inner top end face of the housing 1. A drive motor 8 is electrically connected to one side of the outer wall of the lifting controller 7. The output end of the drive motor 8 passes through the base 13 and is fixedly connected to a transmission wheel 9. A driven wheel 10 is connected to the outer wall of the transmission wheel 9 via a transmission belt. A threaded rod 11 is fixedly connected to one side of the driven wheel 10. A transmission rod 12 is threadedly connected to the top of the threaded rod 11. A fixed seat 14 is fixedly connected to the top of the transmission rod 12. Two limiting rods 15 are fixedly connected to the bottom end of the fixed seat 14. The ends of the two limiting rods 15 away from the fixed seat 14 are fixedly connected to... The top of the housing 1 is attached to the top of the box body 1, and the two limiting rods 15 are located on one side of the bottom sampling tube 2. The top of the fixed base 14 is fixedly connected to the pushing block 16, which is fixedly connected to one side of the top sampling tube 4. The drive motor 8 drives the transmission wheel 9 to rotate, which in turn drives the driven wheel 10 to rotate, causing the threaded rod 11 to rotate and drive the transmission rod 12 to slide up and down. The transmission rod 12 drives the fixed base 14 and the pushing block 16 to drive the top sampling tube 4 to slide up and down. The height is adjusted by the extension and retraction between the top sampling tube 4 and the telescopic sampling tube 3 and the bottom sampling tube 2. The lifting height is controlled by the lifting controller 7 to control the height of the extracted sample.

[0028] In this embodiment, air samples at different heights are extracted and detected through multiple multi-dimensional gradient sampling ports 17 on one side of the outer wall of the bottom sampling tube 2, the telescopic sampling tube 3, and the top sampling tube 4. The detected samples are transmitted through the gas sampling tube 18 into the conduction tube 19, and the gas sample is transmitted to the outlet tube 21 and the diversion gas pipeline 22 by the air pump 20 for transmission to the external detection equipment for detection. This makes the sample extracted by the device more accurate and allows for omnidirectional sample extraction. The drive motor 8 drives the transmission wheel 9 to rotate, which in turn drives the driven wheel 10 to rotate, causing the threaded rod 11 to rotate and drive the transmission rod 12 to slide up and down. The transmission rod 12 drives the fixed seat 14 and the push block 16 to drive the top sampling tube 4 to slide up and down. The height is adjusted by the telescopic sampling tube 3 and the bottom sampling tube 2 through the extension and retraction of the top sampling tube 4. The lifting height is controlled by the lifting controller 7 to control the height of the extracted samples.

[0029] The above specific embodiments are merely several optional embodiments of this utility model.
