[0002] Before and during mining development, the stability of the geological strata where the mine is located needs to be considered. The groundwater ripple data within the geological strata where the mine is located is directly related to the geological conditions. Therefore, it is necessary to sample and analyze the groundwater within the geological strata where the mine is located. Existing samplers generally take samples directly first, then pour out the sampled groundwater for filtration before further analysis. Such samplers do not have built-in filtration functions and cannot quickly filter out large particulate impurities in the groundwater. Utility Model Content

[0022] Drain pipe 3. Detailed Implementation

[0023] To further illustrate the technical means and effects adopted by the utility model in order to achieve the intended purpose of the utility model, the following detailed description of the specific implementation methods, structure, features and effects of the utility model, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0024] Please see Figures 1-6 As shown, the purpose of this embodiment is to provide a mining groundwater sampling device with a built-in filtration function. The mining groundwater sampling device with a built-in filtration function includes a sampling cylinder 1. The sampling cylinder 1 is equipped with a built-in filtration mechanism 2. The built-in filtration mechanism 2 includes an operating rod, a partition, and a filtration part. Rotating the operating rod causes the partition to rotate, and groundwater enters the sampling cylinder 1. Rotating the operating rod causes the filtration part to rotate, which is used to filter the sampled groundwater.

[0025] A drain pipe 3 is fixedly installed at the bottom of the sampling tube 1, and the drain pipe 3 is used to drain the collected water.

[0026] The inner wall of the sampling cylinder 1 is provided with a first annular groove 11 and a second annular groove 12. The first annular groove 11 is located above the second annular groove 12 and the two are parallel to each other. The first annular groove 11 is located between the second annular groove 12 and is connected by at least two parallel vertical strip grooves 13. The bottom of each vertical strip groove 13 is provided with a bottom rectangular groove 14 located below the second annular groove 12.

[0027] The operating lever section includes a first rotating operating lever 21 and a second rotating operating lever 22. The second rotating operating lever 22 is rotatably inserted into the first rotating operating lever 21, and the length of the second rotating operating lever 22 is greater than the length of the first rotating operating lever 21.

[0028] The partition includes an upper partition plate 23 and a lower partition plate 24 that are fitted together. The upper partition plate 23 is fixedly mounted on the first rotating operating rod 21, and the lower partition plate 24 is rotatably mounted on the bottom end of the first rotating operating rod 21 via a bearing. Both the upper partition plate 23 and the lower partition plate 24 have water passage holes 25 inside, and at least two partition plate limiting protrusions 26 are fixed to the periphery of both the upper partition plate 23 and the lower partition plate 24.

[0029] The filtration section includes an upper filter plate 27 and a lower filter plate 28 that are fitted together. The upper filter plate 27 is fixedly mounted on the second rotating operating rod 22, and the lower filter plate 28 is rotatably mounted on the bottom end of the second rotating operating rod 22 via a bearing. Both the upper filter plate 27 and the lower filter plate 28 have water passage holes 25 inside. A filter screen 29 is fixedly installed in the water passage holes 25 on the upper filter plate 27. At least two filter plate limiting protrusions 210 are fixed on the periphery of both the upper filter plate 27 and the lower filter plate 28.

[0030] The partition plate limiting protrusion 26 is slidably disposed in the first annular groove 11, and the filter plate limiting protrusion 210 is slidably disposed in the second annular groove 12. Both the partition plate limiting protrusion 26 and the filter plate limiting protrusion 210 can be slidably disposed in the vertical strip groove 13. The filter plate limiting protrusion 210 on the lower filter plate 28 can be engaged in the bottom rectangular groove 14.

[0031] The first annular groove 11 is provided with a partition plate limiting protrusion 26 corresponding to the partition plate 23, and the second annular groove 12 is provided with a filter plate limiting protrusion 210 corresponding to the filter plate 27.

[0032] The first rotating control lever 21 and the second rotating control lever 22 are long enough to meet the normal groundwater collection requirements.

[0033] Align the partition plate limiting protrusions 26 and 210 on the upper partition plate 23, lower partition plate 24, upper filter plate 27, and lower filter plate 28 so that they are on the same straight line. Then, insert the partition plate limiting protrusions 26 and 210 into the vertical strip groove 13 and slide them into the sampling cylinder 1 along the vertical strip groove 13 until the filter plate limiting protrusion 210 on the lower filter plate 28 is engaged in the bottom rectangular groove 14. At this time, the partition plate limiting protrusion 26 on the upper partition plate 23 is aligned with the first annular groove 11, and the filter plate limiting protrusion 210 on the upper filter plate 27 is aligned with the second annular groove 12. Rotate the first rotating operating rod 21 and the second rotating operating rod 22. The first rotating operating rod 21 drives the upper partition plate 23 and its partition plate limiting protrusion 26 into the first annular groove 11. The cooperation of the first annular groove 11 and the partition plate limiting protrusion 26 provides support for the upper partition plate 23, while the lower partition plate 28... The partition plate limiting protrusion 26 on the partition plate 24 is always located within the vertical strip groove 13 and is limited by the vertical strip groove 13. This setting allows the lower partition plate 24 to remain stationary when the first rotating operating rod 21 drives the upper partition plate 23 to rotate. The second rotating operating rod 22 drives the upper filter plate 27 and its filter plate limiting protrusion 210 into the second annular groove 12. The cooperation between the second annular groove 12 and the filter plate limiting protrusion 210 provides support for the upper filter plate 27. The cooperation between the filter plate limiting protrusion 210 on the lower filter plate 28 and the bottom rectangular groove 14 provides support and limitation for the lower filter plate 28. This setting allows the lower filter plate 28 to remain stationary when the second rotating operating rod 22 drives the upper filter plate 27 to rotate. The installation of the built-in filter mechanism 2 inside the sampling cylinder 1 is completed through the above process. Similarly, the reverse process of the above process can be repeated to achieve the quick removal and disassembly of the built-in filter mechanism 2.

[0034] After the built-in filter mechanism 2 is installed, first plug the drain pipe 3 with a sealing plug, then rotate the first rotating operating rod 21 to drive the upper partition plate 23 to rotate, so that the water passage holes 25 on the upper partition plate 23 and the lower partition plate 24 are aligned with each other; rotate the second rotating operating rod 22 to drive the upper filter plate 27 to rotate, so that the water passage holes 25 on the upper filter plate 27 and the lower filter plate 28 are aligned with each other. The sampling tube 1 is a transparent plastic tube, so the entire process of the above operation can be observed with the naked eye.

[0035] Then, the entire sampling tube 1 is placed in the groundwater. The groundwater flows into the sampling tube 1 and enters the interior of the sampling tube 1 through the water passage holes 25 on the upper partition plate 23 and the lower partition plate 24, as well as the water passage holes 25 on the upper filter plate 27 and the lower filter plate 28. During this process, the groundwater is filtered by the filter screen 29 on the upper filter plate 27, which can effectively filter out large particles of impurities. After the collection is completed, the first rotating operating rod 21 is rotated to drive the upper partition plate 23 to rotate, causing the water passage holes 25 on the upper partition plate 23 and the lower partition plate 24 to be staggered. The second rotating operating rod 22 is rotated to drive the upper filter plate 27 to rotate, causing the water passage holes 25 on the upper filter plate 27 and the lower filter plate 28 to be staggered. At this time, the groundwater sample inside the sampling tube 1 can no longer flow out, thus preventing the groundwater sample inside the moving sampling tube 1 from flowing out.

[0036] The groundwater sample can be taken out by opening the drain pipe 3. The impurities remaining after filtration in the built-in filter mechanism 2 can be poured out by removing the built-in filter mechanism 2 and cleaning the filter screen 29 without affecting the next collection.

[0037] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
