[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0021] Please see Figures 1-6 This utility model provides a technical solution: a hydrogeological exploration sample collection device, including a sampling frame 1, a sampling tube 7, a threaded sleeve 9, and a plug-in rod 8. A connecting column 3 is fixedly installed on the top of the sampling frame 1, and an assembly threaded head 14 is fixedly installed on the top of each connecting column 3. An assembly threaded hole 13 is opened at the bottom of the sampling frame 1. The specifications and dimensions of the external thread of the assembly threaded head 14 are adapted to the specifications and dimensions of the internal thread of the assembly threaded hole 13 and the threaded sleeve 9. Four mounting threaded holes 16 are opened at the bottom of the sampling frame 1. An inner liquid inlet groove 15 is opened on the outer side of the sampling frame 1. An outer frame 2 is rotatably sealed on the outer side of the sampling frame 1. An outer liquid inlet groove 5 is opened on the outer side of the outer frame 2. Two ear blocks 4 are symmetrically fixedly installed on the outer side of the outer frame 2, and each ear block 4 has a plug-in rod inside. The top of the hole 12 and the sampling tube 7 are both fixedly installed with a threaded head 18. The external thread of the threaded head 18 is compatible with the internal thread of the threaded hole 16. The top of the threaded sleeve 9 is rotatably installed with a hand handle 10. The top of the hand handle 10 has a rectangular groove 21. One end of the plug rod 8 is fixedly installed with a rectangular strip 11. The external liquid inlet 5 has the same dimensions as the internal liquid inlet 15. The outer side of the sampling frame 1 has a sealing ring groove 17. The bottom of the outer frame 2 is fixedly installed with a sealing rotating ring 6. The sealing rotating ring 6 is rotatably installed inside the sealing ring groove 17. The outer diameter of the plug rod 8 matches the inner diameter of the plug hole 12. The outer contour of the rectangular strip 11 matches the inner contour of the rectangular groove 21.

[0022] The working principle of the above technical solution is as follows: First, select an appropriate number of sampling frames 1 and a suitable length of insertion rod 8 according to the requirements. Then, assemble multiple sampling frames 1 by simply threading the assembly thread head 14 at the top of the connecting column 3 of one sampling frame 1 to the assembly thread hole 13 at the bottom of another sampling frame 1. Then, thread the threaded sleeve 9 to the outside of the assembly thread head 14 at the top of the connecting column 3 of the topmost sampling frame 1, and insert the insertion rod 8 into the insertion hole 12 inside the ear block 4. Finally, snap the rectangular strip 11 into place. Inside the rectangular slot 21 at the top of the hand crank 10, place the device in water, then rotate the hand crank 10 to drive the insertion rod 8 to rotate, thereby causing the outer frame 2 to rotate outside the sampling frame 1 via the lug 4. This allows water to enter the sampling frame 1 from the outer liquid inlet 5 and the inner liquid inlet 15, and then into the sampling tube 7. After a period of time, rotate the hand crank 10 in reverse, causing the outer frame 2 to rotate outside the sampling frame 1, thus misaligning the outer liquid inlet 5 and the inner liquid inlet 15. Then remove the device from the water to complete the process. Sampling, through multiple sampling frames 1, allows for sampling at different depths in the river, obtaining representative water samples from different water layers. This enables comprehensive and accurate sampling at various depths, significantly improving sampling effectiveness and data reliability. It also allows for more precise understanding of changes in various water quality indicators, providing strong data support for subsequent water quality analysis and environmental protection. Furthermore, the outer frame 2 prevents river water from other layers from entering the sampling frame 1 before it reaches its designated position, effectively isolating it from water at different depths above and around it. This maintains a relatively independent and pure sampling environment within the sampling frame 1, ensuring it is not disturbed by external factors during sampling and greatly improving sampling accuracy. Additionally, removing the sampling frame 1 from the river also prevents river water from entering, ensuring sampling accuracy and preventing contamination of the sampling frame 1 during extraction. This comprehensive improvement in sampling accuracy and reliability provides more accurate data support for water quality monitoring and analysis.

[0023] In another implementation scheme, such as Figures 1-6 As shown, a rotating ring 20 is fixedly installed at the bottom of the hand handle 10, and a rotating groove 19 is provided on the top of the threaded sleeve 9. The rotating ring 20 is rotatably installed inside the rotating groove 19.

[0024] The rotating groove 19 and rotating ring 20 facilitate the rotation of the hand handle 10 on the top of the threaded sleeve 9.

[0025] Working principle: First, select an appropriate number of sampling frames 1 and a suitable length of insertion rod 8 according to the requirements. Then, assemble multiple sampling frames 1. Simply connect the assembly thread head 14 at the top of the connecting post 3 of one sampling frame 1 to the assembly thread hole 13 at the bottom of another sampling frame 1. Then, thread the threaded sleeve 9 to the outside of the assembly thread head 14 at the top of the connecting post 3 of the top sampling frame 1, and insert the insertion rod 8 into the insertion hole 12 inside the ear block 4. Finally, snap the rectangular strip 11 onto the hand handle 1. Place the device inside the rectangular slot 21 at the top of the sampling frame 1, then place the device in the water. Turn the handle 10 to rotate the plug rod 8, which in turn rotates the outer frame 2 outside the sampling frame 1 via the lug 4. This allows water to enter the sampling frame 1 from the outer liquid inlet 5 and the inner liquid inlet 15, and then into the sampling tube 7. After a period of time, turn the handle 10 to reverse the direction, causing the outer frame 2 to reverse outside the sampling frame 1, thus separating the outer liquid inlet 5 and the inner liquid inlet 15. Then remove the device from the water to complete the sampling.
