Description

Technical Field

[0001] This utility model relates to the technical field of groundwater sampling equipment, specifically a groundwater sampler for determining a specific stratum. Background Technology

[0002] Groundwater level refers to the elevation of the water surface in an underground aquifer. Based on the drilling observation time, it can be divided into initial water level, stable water level, water level during the wet season, water level during the dry season, and water level before freezing. Because groundwater has strong stratification, the difference between groundwater at different depths is also different. Before using groundwater, it is necessary to collect and sample the groundwater to understand its water quality composition.

[0003] Chinese Patent No. CN202320782125.9 discloses a groundwater sampler for determining strata, including a groundwater sampling mechanism comprising an outer tube, an upper cover, and a lower cover. The upper and lower ends of the outer tube are respectively engaged with the upper and lower covers. An olive-shaped inner air bladder is provided inside the outer tube, with threaded interfaces at both the upper and lower ends. An outer air bladder with an olive-shaped inner cavity is provided outside the inner air bladder, with the inner cavity of the outer air bladder tightly attached to the outer wall of the inner air bladder. This invention enables the quiet extraction of groundwater without disturbing it, effectively avoiding the muddying of the groundwater and affecting water quality during the extraction process. Furthermore, no external air is injected into the groundwater during extraction, further improving the accuracy of groundwater quality testing.

[0004] Based on the above, the inventors have discovered the following problems: The above-mentioned patent can effectively solve the problem of calmly extracting groundwater without disturbing it, and effectively avoids the situation of muddying the groundwater and affecting the water quality during the pumping process. However, when the groundwater sampler at a fixed stratum is used multiple times, the filter plate on the lower cover of the groundwater sampler will gradually accumulate impurities, causing the pores to become smaller or completely blocked, which will reduce the speed and flow of groundwater extraction, and thus reduce work efficiency.

[0005] Therefore, we have made improvements to this by proposing a groundwater sampler with a fixed stratum. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] This utility model discloses a groundwater sampler for determining a specific stratum, comprising a sampler tube body, an upper cover and a lower cover body respectively installed at the top and bottom of the sampler tube body, a filter screen plate installed at the bottom of the lower cover body, an installation assembly installed between the filter screen plate and the lower cover body, a collar bolted to the surface of the sampler tube body, a clamping device installed on one side of the collar, a water level gauge probe installed inside the clamping device, and a locking pin assembly installed between the water level gauge probe and the clamping device.

[0008] As a preferred technical solution of this utility model, the installation component includes grooves formed on both sides of the lower cover, and locking blocks are installed on both sides of the filter plate. The locking blocks and the grooves are both provided with threaded grooves, and a bolt is installed inside the threaded groove, and the bolt matches the threaded groove.

[0009] As a preferred embodiment of the present invention, the locking pin assembly includes a set of chambers formed inside the locking component. A limiting plate is installed inside the chambers. A spring is installed on one side of the limiting plate, and a movable rod is installed on the other side of the limiting plate. An arc-shaped clamping block is installed on one side of the movable rod, and an anti-slip pad is installed on one side of the arc-shaped clamping block.

[0010] As a preferred embodiment of this utility model, the anti-slip pad and the arc-shaped clamping block are detachably connected.

[0011] As a preferred embodiment of this utility model, a check valve is installed on one side of the upper cover and the lower cover respectively.

[0012] As a preferred embodiment of this utility model, the sampler tube is threadedly connected to the upper cover and the lower cover respectively.

[0013] As a preferred embodiment of this utility model, a water outlet is installed at the center of the upper cover, and an air outlet is provided on one side of the water outlet.

[0014] The beneficial effects of this utility model are:

[0015] 1. This type of groundwater sampler for fixed strata utilizes a combination of a lower cover, groove, filter plate, locking block, threaded groove, and bolt 1. When excessive impurities accumulate on the filter plate on the lower cover, rotating bolt 1 disengages it from the threaded groove, allowing the filter plate with excessive impurities to be removed and replaced with a new one. Through the above design, the new filter plate has larger and cleaner pores, which can maintain a high water flow rate and volume when extracting groundwater. At the same time, replacing the filter plate can reduce the frequency of cleaning and maintenance, saving time and labor costs.

[0016] 2. This type of groundwater sampler with fixed stratification utilizes a combination of clamps, chambers, limiting plates, springs, movable rods, arc-shaped clamping blocks, and anti-slip pads. When it is necessary to clamp the water level gauge probe, the probe is clamped into a set of arc-shaped clamping blocks. The movable rod is under force, and under the action of the spring, the limiting plate moves into the chamber. The arc-shaped clamping blocks clamp and fix the water level gauge probe. Through the above design, the arc-shaped clamping blocks can better conform to the shape of the water level gauge probe, provide uniform clamping force, ensure the stability of the probe during operation, and reduce measurement fluctuations caused by the movement of the water level gauge probe in the water, thereby improving the measurement accuracy of the water level gauge.

[0024] Preferred embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0025] Example: Figure 1-5 As shown, this utility model discloses a groundwater sampler for determining a specific stratum, comprising a sampler tube 1, an upper cover 2 and a lower cover 3 respectively installed at the top and bottom of the sampler tube 1, a filter screen 4 installed at the bottom of the lower cover 3, an installation assembly installed between the filter screen 4 and the lower cover 3, a collar 5 bolted to the surface of the sampler tube 1, a clamp 6 installed on one side of the collar 5, a water level gauge probe 7 installed inside the clamp 6, and a locking pin assembly installed between the water level gauge probe 7 and the clamp 6.

[0026] The installation assembly includes grooves 8 on both sides of the lower cover 3, and locking blocks 9 on both sides of the filter plate 4. Both the locking blocks 9 and the grooves 8 have threaded grooves 10 inside. Bolts 11 are installed inside the threaded grooves 10, and the bolts 11 match the threaded grooves 10. Through the coordinated use of the lower cover 3, grooves 8, filter plate 4, locking blocks 9, threaded grooves 10, and bolts 11, when too many impurities accumulate on the filter plate 4 on the lower cover 3, rotating bolts 11 disengages them from the threaded grooves 10, allowing the filter plate 4 with excessive impurities to be removed and replaced with a new one. This design results in a new filter plate 4 with larger and cleaner pores, maintaining a high water flow rate and volume for groundwater extraction. Furthermore, replacing the filter plate 4 reduces the frequency of cleaning and maintenance, saving time and labor costs.

[0027] The locking assembly includes a set of chambers 12 formed inside the locking piece 6. A limiting plate 13 is installed inside each chamber 12. A spring 14 is installed on one side of the limiting plate 13, and a movable rod 15 is installed on the other side. An arc-shaped clamping block 16 is installed on one side of the movable rod 15, and an anti-slip pad 17 is installed on one side of the arc-shaped clamping block 16. Through the coordinated use of the locking piece 6, chambers 12, limiting plate 13, spring 14, movable rod 15, arc-shaped clamping block 16, and anti-slip pad 17, when water needs to be removed... When the level gauge probe 7 is clamped, it is inserted into a set of arc-shaped clamping blocks 16. The movable rod 15 is subjected to force, and under the action of the spring 14, the limiting plate 13 moves into the cavity 12. The arc-shaped clamping blocks 16 clamp and fix the level gauge probe 7. Through the above design, the arc-shaped clamping blocks 16 can better fit the shape of the level gauge probe 7, provide uniform clamping force, ensure the stability of the probe during operation, and reduce the measurement fluctuation caused by the movement of the level gauge probe 7 in the water, thereby improving the measurement accuracy of the level gauge.

[0028] The anti-slip pad 17 is detachably connected to the arc-shaped clamping block 16. The anti-slip pad 17 can reduce the wear of the arc-shaped clamping block 16 on the water level probe 7, and at the same time increase the friction and improve the stability of clamping.

[0029] Among them, a check valve 18 is installed on one side of the upper cover 2 and the lower cover 3 respectively.

[0030] The sampler tube 1 is threadedly connected to the upper cover 2 and the lower cover 3 respectively.

[0031] The upper cover 2 has a water outlet 19 installed at its center, and an air outlet 20 is provided on one side of the water outlet 19.

[0032] Working Principle: When using this type of fixed-stratum groundwater sampler, the user needs to inspect the internal components or structure of the system. After the inspection is completed, it can be used normally. When the fixed-stratum groundwater sampler is used multiple times, the filter plate 4 on the lower cover 3 will accumulate too many impurities. Rotate bolt 11 to disengage bolt 11 from the threaded groove 10, and the filter plate 4 with excessive impurities can be removed and replaced with a new filter plate 4. The new filter plate 4 has larger and cleaner pores, which can maintain a high water flow rate and volume when extracting groundwater. At the same time, it is necessary to... The water level gauge probe 7 is placed into the underground opening and then clamped into a set of arc-shaped clamping blocks 16. The movable rod 15 is subjected to force, and under the action of the spring 14, the limiting plate 13 moves into the cavity 12. The arc-shaped clamping blocks 16 clamp and fix the water level gauge probe 7, ensuring the stability of the probe during operation. At the same time, it can reduce the measurement fluctuation caused by the movement of the water level gauge probe 7 in the water, thereby improving the measurement accuracy of the water level gauge. The use of anti-slip pads 17 can reduce the wear of the arc-shaped clamping blocks 16 on the water level gauge probe 7, increase friction, and improve the stability of clamping.

[0034] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments.
