Abstract
Description
Technical Field
[0001] This utility model relates to the field of groundwater sampling technology, and in particular to a groundwater recharge sampling device. Background Technology
[0002] Groundwater recharge refers to the artificial injection of surface water or other water sources into the ground, with corresponding requirements for the quality of the recharged water source. Throughout the recharge process, groundwater samples need to be taken and analyzed to observe whether there is groundwater pollution, the impact of recharge on groundwater quality, and the post-recharge groundwater quality status.
[0003] In existing technologies, the sampling process mainly uses containers with fixed openings at the top. When the sampling device falls into the water, it splashes up dust, causing errors between the collected water sample and the actual situation. In addition, after the container falls into the water, a stable water flow cannot be formed inside and outside the container, making it impossible to refresh the water sample inside the container by letting it stand still. As a result, there is always an error between the sampling results and the actual groundwater situation. Utility Model Content
[0004] The purpose of this invention is to provide a groundwater recharge sampling device that can create a stable circulating water flow between the internal space and the outside world, so that the sampling results can accurately reflect the real-time status of the groundwater.

[0006] The first component includes a cylindrical body and a support. The cylindrical body is a cylindrical body that runs vertically through the body, and the support is fixedly connected to the lower end of the cylindrical body.
[0007] The second component includes a handle and a base plate, with the handle fixedly connected to the base plate from above;
[0008] The first and second components are slidably assembled together. Pulling the handle up causes the base plate to move upward, and the cylinder body fits tightly against the base plate under the action of gravity. After releasing the handle, the cylinder body moves away from the base plate under the support of the bracket.
[0009] Preferably, the top surface of the base plate is conical and protrudes upwards, and after pulling the handle upwards, the lower end of the cylinder abuts against the conical top surface of the base plate.

[0030] Combination Figures 1 to 5 As shown, the groundwater recharge sampling device provided by this utility model includes a first component and a second component.
[0031] Combination Figures 1 to 5 As shown, the first component includes a cylindrical body 11 and a support 12. The cylindrical body 11 is a cylindrical body that runs vertically through the body, and the support 12 is fixedly connected to the lower end of the cylindrical body 11. The second component includes a handle 21 and a base plate 22. The handle 21 is fixedly connected to the base plate 22 from above.
[0032] The first component and the second component are slidably assembled together. Pulling up the handle 21 causes the base plate 22 to move upward, and the cylinder 11 is tightly attached to the base plate 22 under the action of gravity. After releasing the handle 21, the cylinder 11 moves away from the base plate 22 under the support of the bracket 12.
[0033] In this embodiment, a container is formed by a cylinder 11 and a bottom plate 22 to store water samples. The cylinder 11 and the bottom plate 22 adopt a split design and a sliding assembly design, so that the container can maintain its permeability by separating the cylinder 11 and the bottom plate 22 during the sampling process, and form a stable circulating water flow. During the process of taking out the water sample, the cylinder 11 and the bottom plate 22 are slidably combined together to form a reliable container to store the water sample, so that the collected water sample accurately reflects the real-time state of the groundwater.
[0034] In this embodiment, the presence of the bracket 12 and the handle 21 can help the cylinder 11 and the base plate 22 to separate and combine. The support of the bracket 12 can help the cylinder 11 move upward away from the base plate 22 in a static state to achieve the separation process. The handle 21 is an operating end extending from the base plate 22. By pulling the handle 21 upward, the cylinder 11 and the base plate 22 can be combined. At the same time, the handle 21 can improve the stability of the sampling process.
[0035] In some embodiments, combined with Figure 2 , Figure 4 As shown, the top surface of the base plate 22 is conical and protrudes upward. After pulling the handle 21, the lower end of the cylinder 11 abuts against the conical top surface of the base plate 22. The protruding top surface is beneficial for the discharge of solid debris on the base plate 22.
[0036] In some embodiments, combined with Figure 1 As shown, a first sliding groove is provided on the inner wall of the cylinder 11, and the handle 21 is slidably assembled in the first sliding groove. The first sliding groove can effectively limit the distance and direction of sliding, and improve working stability. The maximum external dimension of the bottom plate 22 is larger than the diameter of the lower end of the cylinder 11, which can prevent the bottom plate 22 from passing through the inside of the cylinder 11 and falling off.
[0037] In some embodiments, combined with Figure 3 As shown, a sealing block 23 is also fixedly connected to the handle 21. The upper end of the cylinder 11 retracts inward. When the handle 21 is pulled up so that the bottom plate 22 fits tightly against the cylinder 11, the sealing block 23 also fits tightly against the inner wall of the retracted upper end of the cylinder 11. The addition of the sealing block 23, the cylinder 11 and the bottom plate 22 can form a completely sealed container to store water samples, preventing the water samples from being contaminated during the extraction process.
[0038] In some embodiments, combined with Figure 2 As shown, a second sliding groove is provided on the outer wall of the cylinder 11, and the handle 21 is slidably assembled in the second sliding groove. The second sliding groove and the first sliding groove represent two schemes for opening the sliding groove. However, when the cylinder 11 is a cylinder and the handle 21 is close to the outer wall of the cylinder 11, the sliding groove can be omitted because the inner wall of the cylindrical surface has a limiting function. Although it increases the degree of freedom of rotation compared to using a sliding groove, this degree of freedom will not affect the operation of the device.
[0039] In some embodiments, combined with Figures 3 to 5 As shown, a rubber ring 13 is fixedly connected to the lower end of the cylinder 11. After pulling up the handle 21, the rubber ring 13 abuts against the bottom plate 22. By adding a rubber ring 13 at the joint, the sealing connection effect can be improved, and the sealing performance of the container can be improved.
[0040] In some embodiments, combined with Figure 5 As shown, the groundwater recharge sampling device also includes a barrier net 14. The support 12 is evenly distributed along the lower edge of the cylinder 11. The barrier net 14 is fixedly connected between the support 12. The barrier net 14 is flush with the lower edge of the cylinder 11. The barrier net 14 can prevent large solid pieces from getting stuck between the cylinder 11 and the bottom plate 22, ensuring the stability of the connection between the cylinder 11 and the bottom plate 22.
[0041] In some embodiments, combined with Figure 1 As shown, a limiting block 3 is fixedly connected to the lower end of the bracket 12. The limiting block 3 abuts against the bottom surface of the base plate 22. The limiting block 3 can prevent the base plate 22 from moving downward and causing the device to disintegrate.
[0042] In some embodiments, combined with Figure 3 As shown, the groundwater recharge sampling device also includes an annular block 31. The top surface of the annular block 31 is fixedly connected to the support 12, and the annular block 31 abuts against the bottom surface of the base plate 22. The annular block 31 is an optimized version of the aforementioned limiting block 3. While restricting the downward movement of the base plate 22, it increases the support area, making the support more stable and preventing the annular block 31 from sinking into sand and gravel. The use of an annular hollow structure is to increase the area while preventing sand and gravel from accumulating on top and affecting the operation of the device.
[0043] In some embodiments, combined with Figure 5 As shown, the bottom surface of the annular block 31 is fixedly connected to a receiving groove 32, which is annular in shape. Although the above-mentioned container has better accuracy in extracting water samples, it cannot extract solid samples. Extracting solid samples can help operators determine the current water sample extraction position. The addition of the receiving groove 32 can make up for this deficiency. At the same time, the receiving groove 32 can adopt a detachable connection method to increase the flexibility of the device.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
