Description

Technical Field

[0001] The invention relates to the technical field of groundwater detection and sampling, in particular to a groundwater detection and sampling device for geological exploration. Background Art

[0002] Geological exploration is a survey and research activity that uses various means and methods to survey and detect geology, determine the appropriate bearing layer, determine the foundation type based on the bearing capacity of the bearing layer, and calculate the foundation parameters. It is to investigate and study the geological conditions of rocks, strata, structures, minerals, hydrology, landforms, etc. in a certain area in order to find out the quality and quantity of minerals and the technical conditions for mining and utilization, and provide the mineral reserves and geological data required for mine construction design.

[0003] Groundwater sampling has many meanings for geological survey. It not only helps to understand the dynamic changes of groundwater, evaluate groundwater resource reserves, and judge the groundwater quality, but also provides important support for geological structure research and guides geological disaster prevention. Therefore, in the process of geological survey, the role of groundwater sampling should be fully valued; The existing sampling method is basically to open a sampling port on the ground and then take out the groundwater for testing. Before testing, a buffer solution (a mixed solution composed of weak acids and their salts, weak bases and their salts) needs to be dripped into the sample to maintain the stability of the experimental conditions and improve the accuracy of the experimental results.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Example 1, please refer to Figures 1 to 15 , this embodiment provides a technical solution: a groundwater detection and sampling device for geological exploration, including a wire reel 1 and a sampling bucket 5. A handle 2 is fixedly connected to the side of the wire reel 1. The wire end of the wire reel 1 is fixedly connected to the upper end surface of the sampling bucket 5. A notch is provided on the side of the sampling bucket 5. The wall of the notch is hinged with a door 6. And a counterweight 11 is fixedly connected to the lower end surface inside the sampling bucket 5. An inlet water bucket 19 is arranged above the sampling bucket 5. A filter screen 9 is fixedly connected to the upper end surface of the inlet water bucket 19. A sampling assembly is also arranged inside the sampling bucket 5; The sampling assembly includes an airbag 4, a test tube 10, a mounting sleeve 18, and a first water outlet pipe 32. A ventilation pipe 3 is fixedly connected above the airbag 4. The airbag 4 is arranged above a sampling bucket 5. The test tube 10 is arranged inside the sampling bucket 5. A placement rack 29 is clamped on the surface of the test tube 10. A first connecting column 52 is fixedly connected to the inner wall of the placement rack 29. A through hole penetrating to the inside is opened on the upper end surface of the sampling bucket 5. The surface of the through hole is fixedly connected to the outer surface of the upper end of the mounting sleeve 18. A first sliding rod 16 is slidably connected to the inner wall of the mounting sleeve 18. A water inlet groove is opened on the end surface of the first sliding rod 16. The groove wall of the water inlet groove is fixedly connected to the lower end surface of a water inlet bucket 19. A first water outlet 30 is further opened on the side surface of the water inlet groove. A first spring 17 is fixedly connected to the lower end surface of the mounting sleeve 18. The lower end surface of the first spring 17 is fixedly connected to a first connecting plate 15. A first connecting rod 12 is fixedly connected to the upper end surface of the first connecting plate 15. The surface of the first connecting rod 12 slidably penetrates through the upper end surface inside the sampling bucket 5. The upper end surface of the first connecting rod 12 is fixedly connected to the outer surface of the airbag 4. A through groove penetrating to the inside is opened on the side surface of the mounting sleeve 18. The groove wall of the through groove is fixedly connected to the outer surface of one end of the first water outlet pipe 32. The end of the first water outlet pipe 32 away from the mounting sleeve 18 is arranged above the test tube 10.

[0036] More specifically, in this embodiment: The sampling bucket 5 is put into a pre-opened sampling port. The handle 2 is rotated to adjust the length of the wire winding drum 1, so that the sampling bucket 5 descends to an appropriate depth. Then one end of the ventilation pipe 3 is connected to an air pump. When sampling is required, the air pump is used to inflate the airbag 4. After the airbag 4 is inflated, under the action of buoyancy, the airbag 4 will move upward. Further, the first connecting plate 15 is driven to move up and down through the first connecting rod 12, and then the first sliding rod 16 is pushed to move upward. At the same time, the first spring 17 is compressed. When the first sliding rod 16 moves upward until the first water outlet 30 is connected to the first water outlet pipe 32, the sample water in the water inlet bucket 19 will flow into the test tube 10 through the first water outlet pipe 32, thereby realizing the sampling of the sample water. When the sampling is completed, the airbag 4 is deflated again through the air pump, so that the first sliding rod 16 will be driven to reset under the action of the first spring 17, and further the first water outlet 30 and the first water outlet pipe 32 are staggered from each other, thereby stopping the sampling. By using an air pump to inflate the airbag 4, the up and down movement of the first sliding rod 16 is further driven, and further the sampling of groundwater is controlled. Compared with the traditional sampling method, this sampling method is more convenient during the sampling process, and after the height of the sampling bucket 5 is fixed, the groundwater at the same depth can be sampled multiple times.

[0037] It should be noted that this embodiment further includes: a detection sample preparation assembly, which includes a feed pipe 7, a first rotating rod 33, and a first mounting bracket 23. A through mounting groove is provided on the upper end surface of the sampling bucket 5, and the inner wall of the mounting groove is fixedly connected to the outer surface of the feed pipe 7.

The end face of the second water outlet pipe 37 is slidably connected to the end face of the first baffle 35, and the center of the opening end of the second water outlet pipe 37 is concentric with the center of the second leakage groove 36.

[0038] More specifically, in this embodiment: when water flows in the first water outlet pipe 32, it will drive the spiral piece 38 to rotate. The rotation of the spiral piece 38 will further drive the first rotating rod 33 to rotate, and further drive the first baffle 35 to rotate. During the rotation of the first baffle 35, when the first leakage groove 34 and the second leakage groove 36 are aligned, the buffer solution flows into the second water outlet pipe 37 from between the first leakage groove 34 and the second leakage groove 36, and then enters the test tube 10 through the second water outlet pipe 37, realizing the addition of the buffer solution into the test tube 10. When the detection solution is added during subsequent detection, the pH value of the sample solution is maintained within a relatively constant range, and the pH value of the sample solution is kept stable, which can ensure the accuracy and reliability of the detection results, so as to more accurately evaluate the quality and applicability of groundwater. And when adding the buffer solution, it is indirectly added into the test tube 10 as the sample water enters, so that the buffer solution can be more evenly distributed in the test tube 10, making the use effect of the buffer solution better. And because the buffer solution is added along with the flow of the sample water, the ratio of the sample water to the buffer solution basically does not change, which can further prevent the possibility of incorrect metering of the buffer solution.

[0040] More specifically, in this embodiment: during the upward movement of the first connecting plate 15, the first straight tooth row 27 will be driven upward, thereby driving the first tooth ring 22 to rotate. Further, the second straight tooth row 28 will be driven downward, causing the third connecting rod 47 to move downward, so that the fixed column 48 slides within the spiral groove 51, driving the rotating cylinder 49 to rotate one circle. Then, the first rotating disk 46 rotates. Further, the trapezoidal block 45 is used to drive the one-way tooth disk 39 to rotate, driving the placement rack 29 to rotate, thereby driving the test tube 10 to rotate for replacing the test tube 10 for sampling. After sampling, the first connecting plate 15 moves downward under the action of the first spring 17, further driving the third connecting rod 47 to move upward, causing the rotating cylinder 49 to rotate counterclockwise one circle, so that when the inclined surface of the trapezoidal block 45 contacts the one-way tooth disk 39, the trapezoidal block 45 further moves into the groove 59 without driving the one-way tooth disk 39 to rotate.

[0042] More specifically, in this embodiment: the connection plate 15 moves to cause the toothed ring 22 to rotate, and the rotation of the toothed ring 22 further drives the rotating rod 20 to rotate, and the rotation of the rotating rod 20 drives the cam 26 to rotate, further driving the knocking member 21 to swing around the fixed plate 14 as the axis, indirectly knocking the knocking ring 58, driving the placement rack 29 to swing around the swing frame 53 as the axis, and driving the placement rack 29 to recover under the action of the spring 2 56, so that the sample liquid and buffer solution in the test tube 10 can be fully mixed, and because the toothed ring 22 only rotates one circle, it further drives the placement rack 29 to swing only once, thereby preventing the test tube 10 from shaking and causing the sample to spill during the sampling process.

[0043] Working principle: When the groundwater detection sampling device for geological exploration is used, the following steps are performed: Put the sampling bucket 5 into the sampling port set up in advance, turn the handle 2, adjust the length of the wire reel 1, and make the sampling bucket 5 drop to an appropriate depth. Then connect one end of the ventilation tube 3 to the air pump. When sampling is needed, inflate the air bag 4 through the air pump to make the air bag 4 move upward, driving the sliding rod 16 to move upward until the water outlet 30 is connected with the water outlet pipe 32. The sample water in the water inlet bucket 19 will flow into the test tube 10 through the water outlet pipe 32, thereby achieving the sampling of the sample water. When water flows in the outlet pipe 1 32, the spiral piece 38 is driven to rotate, and the rotation of the spiral piece 38 further drives the rotation of the rotating rod 1 33, and further drives the baffle 1 35 to rotate. When the drain groove 1 34 and the drain groove 2 36 are aligned, the buffer solution flows into the outlet pipe 2 37 from between the drain groove 1 34 and the drain groove 2 36, and then enters the test tube 10 through the outlet pipe 2 37. After the sampling is completed, the air bag 4 is deflated again by the air pump, so that the slide is driven under the action of the spring 17. The moving rod 16 is reset, further making the water outlet 30 and the water outlet pipe 32 staggered with each other, thereby stopping sampling. At the same time, the movement of the sliding rod 16 will also drive the cam 26 to rotate, further driving the knocking member 21 to swing around the fixed plate 14 as the axis, knocking the knocking ring 58, and driving the placement frame 29 to swing around the swing frame 53 as the axis, shaking and mixing the liquid in the test tube 10. When the next sampling is required, the air pump is used to inflate the airbag 4 again so that the airbag 4 moves upward and moves. During the process, the straight tooth row 1 27 is driven to move upward, which in turn drives the gear ring 1 22 to rotate, and then drives the straight tooth row 28 to move downward, thereby driving the connecting rod 3 47 to move downward, so that the fixed column 48 slides in the spiral groove 51, driving the rotating cylinder 49 to rotate one circle, thereby causing the rotating disk 1 46 to rotate, and further using the trapezoidal block 45 to drive the one-way toothed disk 39 to rotate, so that the placement rack 29 is driven to rotate, thereby driving the test tube 10 to rotate, and the test tube 10 is replaced to achieve multiple sampling.
