Description

Technical Field

[0001] This utility model relates to the technical field of soil storage devices, and in particular to a sample storage device for detecting heavy metals in soil. Background Technology

[0002] With the acceleration of industrialization and urbanization, soil pollution has become increasingly serious, especially heavy metal pollution, which poses a severe threat to the ecological environment and human health. Heavy metals such as lead (Pb), cadmium (Cd), mercury (Hg), and chromium (Cr), due to their persistent degradation and bioaccumulation, have become a key focus of soil environmental monitoring and remediation. To accurately assess the degree of heavy metal pollution in soil, soil heavy metal detection sample storage devices are used.

[0003] However, existing soil heavy metal testing sample storage devices still have certain drawbacks. For example, soil samples are usually stored in test tubes, and when taking out samples using traditional soil sample storage devices, it is usually necessary to invert the test tube and use inertia to forcefully throw out the soil or use tools to dig. These methods are not only time-consuming but also laborious. Utility Model Content

[0004] The purpose of this invention is to provide a sample storage device for soil heavy metal detection. After the lid is closed, the silicone plug can be pressed tightly by a pull ring, thereby improving the sealing of the sample tube and effectively preventing the possibility of soil leakage. The soil sample stored inside the sample tube can be easily ejected as needed, thereby improving the efficiency of subsequent detection of heavy metals in the soil.

[0005] To achieve the above objectives, a sample storage device for soil heavy metal detection is provided, comprising:

[0028] A mounting frame 22 is fixedly connected to the inner surface of the storage box 1. A top rod 10 is fixedly connected to the upper surface of the mounting frame 22. A placement groove 11 is provided on the upper surface of the mounting frame 22. A sample tube 12 is slidably connected to the inner surface of the placement groove 11. A silicone stopper 13 is slidably connected to the inner surface of the sample tube 12. A limiting plate 14 is fixedly connected to the upper surface of the silicone stopper 13 to limit its position. A pull ring 15 is fixedly connected to the upper surface of the limiting plate 14 to facilitate the removal of the silicone stopper 13. A handle groove 16 is provided on the outer surface of the sample tube 12 to facilitate the removal and placement of the sample tube 12 as a whole. A sliding column 17 is slidably connected to the inner surface of the sample tube 12. A limiting ring 18 is fixedly connected to the outer surface of the slide column 17. A second spring 19 is provided on the outer surface of the slide column 17. A top plate 20 is fixedly connected to the upper end of the slide column 17. The lower surface of the soft rubber pad 9 is in contact with the pull ring 15 to facilitate the pressing operation of the silicone plug 13. There are three placement slots 11, which are linearly distributed from left to right. The upper surface of the sample tube 12 is in contact with the limiting plate 14. The upper end of the second spring 19 is fixedly connected to the sample tube 12. The lower end of the second spring 19 is fixedly connected to the limiting ring 18. The outer surface of the top plate 20 is slidably connected to the sample tube 12. The outer surface of the limiting ring 18 is slidably connected to the sample tube 12 to facilitate the removal of soil from inside the sample tube 12.

[0029] Working principle: During operation, firstly, push the L-shaped insert 8 backward along the slide rod 6 inside the slide groove 5, and the first spring 7 will be hydraulically activated, causing the L-shaped insert 8 to disengage from the slot 21. Then, open the box cover 2, pull out the entire sample tube 12 from the placement slot 11, and then use the pull ring 15 to open the silicone plug 13. Next, pour the soil to be tested into the sample tube 12 for storage, and then re-insert the silicone plug 13 into the opening of the sample tube 12 to seal the soil inside the sample tube 12. Then, close the box cover 2. When the L-shaped insert 8 corresponds to the slot 21, release the L-shaped insert 8. Under the rebound force of the first spring 7, the L-shaped insert 8 will automatically insert into the slot 21, thus completing the closure of the box cover 2. During the closing process of the box cover 2, the soft rubber pad 9 will contact the pull ring 15 and continue to squeeze the pull ring 15. Finally, the deformation of the soft rubber pad 9 will press the pull ring 15 tightly, thereby ensuring the sample is sealed. The overall sealing of the sample tube 12 reduces the possibility of soil leakage. When it is necessary to test the soil inside the sample tube 12, simply open the box cover 2 as described above, then take out the entire sample tube 12 along the inside of the placement groove 11, and then pull the pull ring 15 to open the silicone stopper 13. Then, select an appropriate soil removal method according to the amount of soil inside the sample tube 12. When the amount of soil inside the sample tube 12 is small, the sliding column 17 below the sample tube 12 can be aligned with the top rod 10 and pressed down. Under the action of the top plate 20, the soil to be tested can be pushed out a distance to avoid excessive friction between the soil and the inner wall of the sample tube 12, which would make it difficult to pour out the soil, thereby improving the efficiency of subsequent testing operations. When the amount of soil inside the sample tube 12 is large, simply invert the sample tube 12 and then manually press the sliding column 17 to push out the soil inside the sample tube 12. It is simple, convenient and practical.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
