A storage device for groundwater detection

Abstract

This utility model relates to the field of sample storage technology and discloses a storage device for groundwater testing. The novel device includes an outer tube with a buffer liner on its inner wall. A glass test tube is placed inside the buffer liner, and a first buffer pad is provided at the bottom of the glass test tube. This utility model uses a second buffer pad, a buffer liner, and a first buffer pad to enclose the glass test tube, thus providing impact protection. By separating the hand-tightened bolt from the outer tube and the insert, a sliding plate can be pushed upwards, causing the base to move the glass test tube upwards. This facilitates the tester in removing the glass test tube from the outer tube to test the stored groundwater sample. Furthermore, as the glass test tube moves upwards, the sealing plug remains inserted inside the tube opening, preventing the sample from spilling when the glass test tube is removed from the outer tube, thereby improving reliability.

Description

Technical Field

[0001] This utility model belongs to the field of sample storage technology, specifically a storage device for groundwater detection. Background Technology

[0002] With the deepening of water resource protection and environmental monitoring, groundwater testing has become a crucial link in ensuring ecological security and the health of residents' drinking water. In the groundwater testing process, sample collection and storage are fundamental steps for obtaining accurate test data, and their quality directly affects the reliability of subsequent test results. Currently, glass test tubes, with their advantages of high chemical stability, good transparency, and low cost, have become a commonly used storage device for groundwater sampling. They allow for clear observation of the sample's condition and are less likely to react chemically with the water sample, ensuring the authenticity and validity of the test data.

[0003] However, the brittle and impact-resistant nature of glass test tubes presents significant drawbacks during transportation and storage. Groundwater sampling often requires operation in complex field environments, necessitating the traversing of mountains and jungles, with sampling sites potentially located in inaccessible and rugged areas. At the sampling site, glass test tubes are easily broken by impacts or drops, leading to water leakage or contamination. During transportation, vehicle bumps and handling operations can also cause breakage. A broken glass test tube not only results in the loss of valuable groundwater samples, rendering the sampling effort futile and increasing testing costs and time, but also poses a safety hazard due to broken glass potentially injuring sampling personnel. Therefore, we propose a storage device for groundwater testing. Utility Model Content

[0004] The purpose of this invention is to provide a storage device for groundwater testing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a storage device for groundwater testing, comprising an outer tube, a buffer liner provided on the inner wall of the outer tube, a glass test tube disposed inside the buffer liner, a first buffer pad provided at the bottom of the glass test tube, a base provided at the bottom of the first buffer pad, a sliding plate installed on the outer side of the base, a tube cap fitted onto the top of the outer tube, a second buffer pad and a sealing plug installed between the glass test tube and the tube cap, and an anti-loosening hand-tightening bolt installed between the tube cap, the sliding plate, and the outer tube.

[0006] Preferably, both the base and the first buffer pad are disposed inside the buffer liner, and the base is disposed at the bottom of the inner side wall of the outer sleeve.

[0007] Preferably, a set of sliding grooves is provided through both the left and right sides of the outer tube and the buffer liner, and a set of connecting blocks is provided on both the left and right sides of the base.

[0008] Preferably, the connecting block is disposed within the slide groove, and the slide plate is located outside the outer sleeve.

[0009] Preferably, the second buffer pad is disposed on the top of the inner wall of the tube cap, the sealing plug is disposed at the bottom of the second buffer pad, the bottom of the second buffer pad is in contact with the top of the glass test tube, and the sealing plug is inserted into the opening of the glass test tube.

[0010] Preferably, the top of the slide plate is provided with an insert block, and a set of slots is provided on both the left and right sides of the inner sidewall of the tube cover. The slots penetrate the bottom of the tube cover, and the insert block is inserted into the slot. A first threaded hole is provided through the outer side of the slot, and a through hole is provided through the outer side of the insert block. A set of second threaded holes is provided on both the left and right sides of the outer tube. The anti-loosening hand-tightening bolt is screwed into the first threaded hole, and the anti-loosening hand-tightening bolt is screwed through the through hole and the second threaded hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the glass test tube is wrapped by the second buffer pad, the buffer liner and the first buffer pad, thereby protecting the glass test tube from impact. After the hand-tightened bolt is separated from the outer tube and the insert, the sliding plate can be pushed upward to drive the base to move the glass test tube upward. This makes it convenient for the tester to take the glass test tube out of the outer tube to test the stored groundwater sample. When the glass test tube moves upward, the sealing plug will always be inserted into the mouth of the glass test tube, thereby preventing the sample stored in the glass test tube from spilling when the glass test tube is taken out of the outer tube, thus improving the reliability of use.

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.

[0019] Please see Figure 1-3 A groundwater testing storage device includes an outer tube 1, a buffer liner 18 fixedly installed on the inner wall of the outer tube 1, a glass test tube 14 slidably installed inside the buffer liner 18, a first buffer pad 16 slidably installed at the bottom of the glass test tube 14, a base 15 fixedly installed at the bottom of the first buffer pad 16, a sliding plate 13 installed on the outside of the base 15, a tube cap 11 fitted onto the top of the outer tube 1, a second buffer pad 2 and a sealing plug 21 installed between the glass test tube 14 and the tube cap 11, sealing the opening of the glass test tube 14 with the sealing plug 21. The glass test tube 14 is wrapped by the second buffer pad 2, the buffer liner 18 and the first buffer pad 16 to protect it from impact. An anti-loosening hand-tightening bolt 12 is installed between the tube cap 11, the sliding plate 13 and the outer tube 1. The base 15 and the first buffer pad 16 are both slidably installed inside the buffer liner 18. 5. A sliding groove is provided on the bottom of the inner wall of the outer tube 1. A set of sliding grooves is provided on both the left and right sides of the outer tube 1 and the buffer liner 18. A set of connecting blocks 17 are fixedly provided on both the left and right sides of the base 15. The connecting blocks 17 are slidably provided in the sliding grooves. The sliding plate 13 is located on the outside of the outer tube 1. Pushing the sliding plate 13 upward will drive the base 15 to move upward through the connecting blocks 17. The base 15 will drive the glass test tube 14 to move upward through the first buffer pad 16. This makes it convenient for the tester to take the glass test tube 14 out of the outer tube 1 to test the stored groundwater sample. When the glass test tube 14 moves upward, it will drive the tube cap 11 to move upward together. During the upward movement of the glass test tube 14, the sealing plug 21 will always be inserted into the opening of the glass test tube 14 to prevent the sample stored in the glass test tube 14 from spilling out when the glass test tube 14 is taken out of the outer tube 1, thereby improving the reliability of use.

[0020] The second buffer pad 2 is fixedly installed on the top of the inner wall of the tube cap 11, and the sealing plug 21 is fixedly installed at the bottom of the second buffer pad 2. The bottom of the second buffer pad 2 is in contact with the top of the glass test tube 14, and the sealing plug 21 is inserted into the tube opening of the glass test tube 14. The top of the slide plate 13 is fixedly provided with an insert block 19. A set of slots is opened on both the left and right sides of the inner wall of the tube cap 11. The slots penetrate the bottom of the tube cap 11, and the insert block 19 is inserted into the slots. A first threaded hole is opened through the outside of the slots, and a through hole is opened through the outside of the insert block 19. A set of second threaded holes is opened on both the left and right sides of the outer tube 1. The anti-loosening hand-tightening bolt 12 is screwed into the first threaded hole. The anti-loosening hand-tightening bolt 12 is screwed through the through hole and connected to the second threaded hole. The anti-loosening hand-tightening bolt 12 is screwed to the first threaded hole of the tube cap 11, and through the through hole of the insert block 19 and connected to the second threaded hole of the outer tube 1. In this way, the tube cap 11 and the slide plate 13 can be fixed to the outside of the outer tube 1.

[0021] Working principle: The anti-loosening hand-tightening bolt 12 is screwed into the first threaded hole of the tube cap 11, and the through hole of the insert 19 is screwed into the second threaded hole of the outer tube 1. This fixes the tube cap 11 and the sliding plate 13 to the outside of the outer tube 1. The opening of the glass test tube 14 is sealed by the sealing plug 21. The glass test tube 14 is wrapped by the second buffer pad 2, the buffer liner 18, and the first buffer pad 16 to protect it from impact. By rotating the anti-loosening hand-tightening bolt 12 to separate it from the outer tube 1 and the insert 19, the sliding plate 13 can be pushed upward. The connecting block 17 drives the base 15 to move upward, and the base 15 drives the glass test tube 14 to move upward through the first buffer pad 16. This makes it easier for the tester to take the glass test tube 14 out of the outer tube 1 to test the stored groundwater sample. When the glass test tube 14 moves upward, it will also drive the tube cap 11 to move upward. During the upward movement of the glass test tube 14, the sealing plug 21 will always be inserted into the opening of the glass test tube 14 to prevent the sample stored in the glass test tube 14 from spilling out when it is taken out of the outer tube 1, thereby improving the reliability of use.
