Description

Technical Field

[0001] This utility model relates to the technical field of water sampling equipment, and in particular to a water sampling device for environmental monitoring. Background Technology

[0002] In the field of environmental monitoring, water sampling is a crucial step in analyzing the distribution of water pollution and the vertical variation of its composition. Traditional water sampling methods have significant drawbacks: when using a single container to scoop or a simple pull-out sampler, obtaining water samples from different depths requires multiple operations, which is not only inefficient but also prone to sample mixing due to operational errors, affecting the accuracy of the test. Therefore, there is an urgent need for a water sampling device that can efficiently and accurately perform stratified sampling and is easy to operate. Utility Model Content

[0003] This invention provides a water sampling device for environmental monitoring, which solves the problems of traditional sampling devices in the prior art that require multiple operations to obtain water samples at different depths, resulting in low efficiency and easy mixing of water samples.

[0004] The technical problem solved by this utility model is achieved by the following technical solution:

[0005] A water sampling device for environmental monitoring, comprising:

[0006] The sample storage box tube includes a tube body and a liquid inlet longitudinally opened on the tube body. A plug-in seat is provided at the lower end of the tube body. A partition plate is provided inside the tube body to divide the inside of the tube body into a chamber for liquid storage.

[0007] The sleeve section includes a sleeve fitted onto the tube body and flow guide holes formed around the sleeve, wherein the opening height of each set of flow guide holes is the same as the height of the liquid inlet.

[0008] A rotation adjustment part is connected and installed at the upper end of the sample storage box tube and connected to the sleeve part to adjust the rotation of the sleeve part.

[0009] In one specific implementation, the upper end of the connector is provided with a positioning slot.

[0010] In one specific implementation, a positioning ring is provided at the lower end of the sleeve, and the positioning ring is positioned and inserted into the positioning slot;

[0011] The inner wall of the sleeve is fixedly provided with a rubber inner tube for sealing.

[0012] In one specific implementation, a cover plate is detachably installed at the upper end of the tube body by bolts, and a positioning stop is provided at the lower end of the cover plate, which blocks the inner edge of the upper end of the sleeve.

[0013] In one specific implementation, the rotation adjustment part includes:

[0014] A rotating connecting bracket is provided, the lower end of which is connected to the upper end of the sleeve.

[0015] A positioning post, the lower end of which is connected and installed on the cover plate and passes through the upper end of the rotating connecting frame.

[0016] In one specific implementation, the rotating connecting frame includes:

[0017] A connecting post, the lower end of which is fixedly welded to the upper end of the sleeve;

[0018] A central perforated plate, which is fixedly welded to the upper end of the connecting column;

[0019] A push rod is fixedly welded to the edge of the upper end face of the central hole plate.

[0020] In one specific implementation, the positioning post includes:

[0021] Guide post, which is inserted and installed in the center hole of the center plate;

[0022] A connecting end is provided at the lower end of the guide post and is mounted on the cover plate by bolts;

Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] Example 1

[0051] Reference Figures 1-6 As shown, this utility model provides a water sampling device for environmental monitoring, comprising:

[0052] The sample storage box tube section 100 includes a tube body 110 and a liquid inlet 120 longitudinally opened on the tube body 110. A plug-in seat 130 is provided at the lower end of the tube body 110. A partition plate 140 is provided inside the tube body 110, and the partition plate 140 divides the inside of the tube body 110 to form a chamber for liquid storage.

[0053] The sleeve section 200 includes a sleeve 210 fitted onto the tube body 110 and flow guide holes 220 formed around the sleeve 210. The opening height of each set of flow guide holes 220 is the same as the height of the liquid inlet 120.

[0054] The rotation adjustment unit 300 is connected to the upper end of the sample storage box tube section 100 and is connected to the sleeve section 200 to adjust the rotation of the sleeve section 200.

[0055] In this embodiment, two sets of partition plates 140 are provided, dividing the interior of the tube body 110 into three chambers for storing water. Three sets of inlet ports 120 and guide holes 220 are also provided, with each set of inlet ports 120 located below the corresponding chamber. The opening orientation of each set of guide holes 220 is different, and the angle between the opening orientations of adjacent guide holes 220 is 90°. Therefore, a portion of the sleeve 210 is in a complete state without guide holes 220. This portion of the sleeve 210 without guide holes 220 can block the inlet port 120. By rotating the sleeve 210, the guide holes 220 are aligned with the inlet port 120, and the water to be sampled enters the chamber through the inlet port 120, completing the water sampling.

[0056] The tube body 110 is divided into multiple completely independent sealed chambers by the partition plate 140. Combined with the guide holes on the sleeve 210, which are distributed at different heights and staggered at 90° to adjacent orientations, precise water samples can be collected sequentially from different depths during a single dive. This overcomes the limitations of traditional samplers, which can only obtain water samples from a single depth or are prone to mixing and contamination from multiple depths. It is particularly suitable for environmental monitoring and analysis of water bodies with distinct water quality stratification characteristics.

[0057] As a further preferred embodiment of the above-described embodiment, the upper end of the connector 130 is provided with a positioning slot 131.

[0058] As a further preferred embodiment of the above-described embodiment, a positioning insert ring 230 is provided at the lower end of the sleeve 210, and the positioning insert ring 230 is positioned and inserted into the positioning slot 131.

[0059] The inner wall of the sleeve 210 is fixedly provided with a rubber inner tube 211 for sealing.

[0060] The positioning ring 230 at the lower end of the sleeve 210 and the positioning slot 131 of the connector 130 cooperate to ensure the coaxiality of the sleeve 210 when it rotates. The rubber inner tube 211 on the inner wall of the sleeve 210 enhances the fit and sealing with the tube body 110, which can effectively prevent water from leaking from the gap between the sleeve 210 and the tube body 110, thus avoiding crosstalk between water samples at different depths and preventing the leakage and loss of collected water samples.

[0061] As a further preferred embodiment of the above embodiment, a cover plate 400 is detachably installed on the upper end of the pipe body 110 by bolts, and a positioning stop 410 is provided on the lower end of the cover plate 400, which blocks the inner edge of the upper end of the sleeve 210.

[0062] The positioning stop 410 at the lower end of the cover plate 400 blocks the inner edge of the upper end of the sleeve 210, restricting the axial displacement of the sleeve 210, so that the sleeve 210 can only rotate circumferentially along the tube body 110.

[0063] As a further preferred embodiment of the above-described embodiment, the rotation adjustment unit 300 includes:

[0064] Rotate the connecting bracket 310, with the lower end of the rotating connecting bracket 310 connected to the upper end of the sleeve 210;

[0065] The lower end of the positioning post 320 is connected and installed on the cover plate 400, and passes through the upper end of the rotating connecting frame 310.

[0066] Furthermore, the rotating connecting bracket 310 includes:

[0067] Connecting post 311, the lower end of which is fixedly welded to the upper end of sleeve 210;

[0068] A central hole plate 312 is fixedly welded to the upper end of the connecting column 311;

[0069] Push rod 313 is fixedly welded to the edge of the upper end face of the central hole plate 312.

[0070] Furthermore, the positioning post 320 includes:

[0071] Guide post 321 is inserted into the center hole of center hole plate 312;

[0072] The connecting end 322 is located at the lower end of the guide post 321 and is installed on the cover plate 400 by bolts;

[0073] The gripping end 323 is located at the upper end of the guide post 321.

[0074] During use, the part of the sleeve 210 without the guide hole 220 blocks the inlet 120. By holding the grip end 323, the sample collection box tube 100 is placed in the water. After the sample collection box tube 100 is inserted into the sampling water depth, the push rod 313 is manually rotated to drive the sleeve 210 to rotate around the tube body 110. First, it is rotated 90° so that the guide hole 220 at the bottom of the sleeve 210 is aligned with the inlet 120 at the bottom of the tube body 110. The water at this depth flows into the lowermost chamber of the tube body 110 through the inlet 120. Then, it is rotated 45° so that the guide hole 220 at the bottom is deviated from the inlet 120 at the bottom of the tube body 110. The inlet 120 is blocked by the sleeve 210 to prevent the collected water from flowing out of the lowermost chamber. After the sample storage box tube 100 is extended further into a deeper water layer, it is rotated 45° so that the guide hole 220 in the middle of the sleeve 210 is aligned with the liquid inlet 120 in the middle of the tube body 110. The water at this depth flows into the cavity in the middle of the tube body 110 through the liquid inlet 120. Then, it is rotated 45° so that the guide hole 220 at the bottom end is offset from the liquid inlet 120 at the bottom end of the tube body 110, and the liquid inlet 120 is blocked by the sleeve 210. Similarly, if sampling is required at deeper water levels, simply extend the sample container tube 100 further into the deeper water layer, then rotate it 45° so that the uppermost guide hole 220 of the sleeve 210 aligns with the uppermost inlet 120 of the tube body 110. This time, the lower guide holes 220 are offset from the inlet 120. After water is filled in the uppermost chamber, rotate it another 45° to completely block the inlet 120 from the portion of the sleeve 210 without the guide holes 220. Then pull out the sample container tube 100. After pulling out the sample container tube 100, rotate the sleeve 210 on land to align the guide holes 220 with the inlet 120 sequentially, and then pour out the water from each chamber in turn.

[0075] Example 2

[0076] Reference Figures 7-9 As shown, this is the second embodiment of the present invention. This embodiment is based on the previous embodiment and optimizes and modifies the rotation adjustment part 300 in the above embodiment.

[0077] Specifically, the rotation adjustment unit 300 includes:

[0078] Rotation drive component 330 is mounted on cover plate 400;

[0079] Holding rod 340, the lower end of holding rod 340 is connected and installed on the sealing cover of rotating drive component 330;

[0080] Gear ring 350 is fixedly welded to the upper end of sleeve 210 and meshes with rotating drive component 330.

[0081] Furthermore, the rotation drive 330 includes:

[0082] Drive motor 331 is mounted on cover plate 400 and is located inside the sealing cover. The output end of drive motor 331 extends out from inside the sealing cover.

[0083] The drive gear 332 is mounted on the output end of the drive motor 331 and meshes with the gear ring 350.

[0084] Furthermore, the holding rod 340 is a long tube structure, and the lower end of the long tube holding rod 340 is connected to the sealing cover of the rotation drive component 330 for arranging the control line of the drive motor 331.

[0085] In use, the drive motor 331 drives the drive gear 332 to rotate, which in turn drives the sleeve 210 with the gear ring 350 on the upper end to rotate. Compared with manually adjusting the rotation of the sleeve 210, the rotation angle of the sleeve 210 can be controlled more precisely, and it is more labor-saving and efficient.
