Description

Technical Field

[0001] This utility model relates to the field of geological hazard assessment technology, specifically a portable sampling device for assessing geological hazards in mines. Background Technology

[0002] Geological hazards refer to geological processes or phenomena that cause loss to human life and property and damage to the environment under the influence of natural or human factors. The distribution and variation of geological hazards in time and space are subject to both the natural environment and human activities, and are often the result of the interaction between humans and nature. Soil sampling is required during the assessment, which necessitates the use of sampling devices.

[0003] For example, Chinese Utility Model Patent No. CN212693313U, entitled "A Portable Sampling Device for Geological Hazard Assessment," includes a cylindrical body, a soil sampling mechanism, a sleeve mechanism, and a soil shoveling mechanism. The soil sampling mechanism is mounted on the upper end of the cylindrical body and includes a handle with side handles at both ends. An inner column is mounted on the lower end of the handle, a spiral layer is mounted on the outer side of the inner column, and a spiral bottom is mounted on the bottom end of the inner column. The cylindrical body includes a sleeve mechanism, which includes a first sleeve cover, and a second sleeve cover is mounted on the lower end of the first sleeve cover. This utility model uses a portable, stacked syringe to sample soil by rotating a spiral. It also features a foldable and fixed digging shovel for easy removal of the upper soil layer and sampling of the inner soil, achieving the effects of portability, convenient sampling, and access to the bottom soil layer.

[0004] While the aforementioned document achieves the effects of being portable, convenient for sampling, and able to obtain bottom soil samples, it still has the drawback of not being able to easily disassemble the sampling head. The sampling head will reduce its sampling effect after long-term operation and requires regular maintenance or replacement. The inconvenience of disassembly causes trouble for users and thus cannot meet their needs. Therefore, we propose a portable sampling device for mine geological hazard assessment.

[0023] Example 1:

[0024] Please see Figure 1-4As shown, this utility model provides a portable sampling device for assessing geological hazards in mines, including a base plate 1. A vertical plate 2 is fixedly connected to the top left side of the base plate 1. A first cylinder 4 is fixedly connected to the top and bottom of the right side of the vertical plate 2. An adjustment box 5 is fixedly connected to the output end of the first cylinder 4. A second motor 13 is fixedly connected to the top of the inner cavity of the adjustment box 5. A threaded rod 18 is fixedly connected to the output end of the second motor 13. A threaded block 17 is threadedly connected to the outer surface of the threaded rod 18. An adjustment plate 6 is fixedly connected to the right side of the threaded block 17. A first motor 7 is fixedly connected to the bottom of the adjustment plate 6. A housing 8 is fixedly connected to the output end of the first motor 7. Electric telescopic rods 19 are fixedly connected to both sides of the inner cavity of the housing 8. A fixing plate 20 is fixedly connected to the telescopic end of the electric telescopic rod 19. A sampling head 9 is provided on the inner side of the fixing plate 20. Several storage slots 12 are opened on the top right side of the base plate 1.

[0025] This technical solution incorporates an electric telescopic rod 19 and a fixing plate 20. The electric telescopic rod 19 drives the fixing plate 20 to move outward, which eliminates the need to fix the sampling head 9. This allows the sampling head 9 to be easily pulled out of the through hole, facilitating maintenance or replacement and preventing long-term use from reducing the sampling effect, thus meeting the user's needs. Example 2:

[0026] Based on Embodiment 1, this utility model is as follows: Figure 1-4 As shown, a push handle is fixedly connected to the left side of the top of the base plate 1, and movable wheels 11 are fixedly installed around the bottom of the base plate 1. A housing 10 is fixedly connected to the rear end of the top right side of the base plate 1. A third cylinder 23 is fixedly connected to the top of the inner cavity of the housing 10. A second cylinder 16 is fixedly connected to the output end of the third cylinder 23. A baffle 3 is fixedly connected to the output end of the second cylinder 16. A second slider 22 is fixedly connected to the rear end of the third cylinder 23. A sliding groove 21 is provided at the rear end of the inner cavity of the housing 10. The outer surface of the second slider 22 is slidably connected to the inner surface of the sliding groove 21.

[0027] Using the above technical solution, through the setting of the third cylinder 23, the second cylinder 16 and the baffle 3, the second cylinder 16 drives the baffle 3 to reach above the storage tank 12, and the third cylinder 23 drives the baffle 3 to move downward, which can cover the sampled soil and prevent debris from falling in and affecting subsequent testing. Through the setting of the second slider 22 and the slide 21, the third cylinder 23 can be made more stable when moving up and down. Example 3:

[0028] This utility model is as follows Figure 1-4As shown, a first slider 14 is fixedly connected to the left side of the threaded block 17, and a slide rail 15 is fixedly connected to the left side of the inner cavity of the adjustment box 5. The outer surface of the first slider 14 is slidably connected to the inner surface of the slide rail 15. A bearing is provided at the bottom of the threaded rod 18, and a protective sleeve is provided on the surface of the bearing. A through hole is opened at the bottom of the housing 8, and the diameter of the through hole is larger than the diameter of the sampling head 9.

[0029] By adopting the above technical solution, the first slider 14 and slide rail 15 can make the threaded block 17 more stable when moving up and down. The bearing can reduce the friction when the threaded rod 18 rotates. The protective sleeve can protect the threaded rod 18. The through hole can facilitate the removal of the sampling head 9 for maintenance or replacement.

[0030] The working principle of this utility model is as follows: First, the device can be moved to the sampling position by the movable wheel 11. Then, the first cylinder 4 is opened by the external controller. The first cylinder 4 pushes the adjusting box 5 and the sampling head 9 above the sampling position. Then, the second motor 13 and the first motor 7 are opened by the external controller. The second motor 13 drives the threaded rod 18 to rotate. The threaded rod 18 drives the threaded block 17 and the adjusting plate 6 to move downward. The adjusting plate 6 drives the first motor 7 and the sampling head 9 to move downward. At the same time, the first motor 7 drives the sampling head 9 to rotate for sampling. No manual operation by the operator is required. After sampling is completed, the first cylinder 4 is opened to drive the sampling head 9 to the storage position. Above the storage trough 12, the sampled soil can be stored separately. Then, the second cylinder 16 and the third cylinder 23 are opened by the external controller. The second cylinder 16 drives the baffle 3 to move above the storage trough 12, and the third cylinder 23 drives the baffle 3 to move downward, which can cover the sampled soil to prevent debris from falling in and affecting subsequent testing. Then, the electric telescopic rod 19 is opened by the external controller. The electric telescopic rod 19 drives the fixing plate 20 to move outward, which can remove the fixing of the sampling head 9, making it easy to pull the sampling head 9 out of the through hole, thereby facilitating maintenance or replacement and preventing long-term use from reducing the sampling effect, thus meeting the needs of users.
