Description

Technical Field

[0001] This utility model relates to the field of hydrogeology, and more specifically, to a water sample storage tank for hydrogeology. Background Technology

[0002] Hydrogeology is the study of the formation, distribution, movement patterns of groundwater and its interaction with the surrounding environment. In hydrogeological exploration and water resource assessment, water samples from different regions and strata need to be collected to analyze water quality components and monitor water resource dynamics. After collection, the water samples need to be temporarily stored in storage tanks for transportation to the laboratory for testing. Therefore, water sample storage tanks are key instruments for ensuring water sample quality and facilitating sample transfer in hydrogeological work.

[0003] In current hydrogeological work, it is often necessary to collect and store multiple water samples from different areas and depths at the same time, which requires the use of multiple water sample storage tanks. However, traditional water sample storage tanks are mostly single, independent, and sealed structures. In actual operation, the sealing operation is cumbersome and inefficient. Each tank is mostly sealed by screwing or snapping, and staff have to handle them one by one. When storing water samples in batches, the sealing efficiency is extremely low, which seriously affects the progress of field operations. Utility Model Content

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. A rotary drive structure consisting of a servo motor, drive shaft, thin-walled bearing, stabilizing ring, and drive disk is used. The servo motor drives the drive shaft to rotate, and the drive shaft, through the cooperation of the stabilizing ring and the thin-walled bearing, makes the drive disk rotate smoothly. Multiple storage tanks are fixed on the drive disk and can be rotated to the open area of ​​the auxiliary closing pressure plate as needed. There is no need to manually operate them one by one. It can efficiently realize the positioning and retrieval of batch storage tanks, solve the problem of low sealing efficiency of traditional independent sealing structures. With the limit effect of the auxiliary closing pressure plate on multiple sealing caps, when the storage tank rotates to the open area, the sealing cap can be opened and closed, while the other sealing caps are pressed down by the pressure plate to maintain the seal. This achieves the combination of rapid opening and closing and batch sealing, improves the progress of field operations, and avoids the time waste and low efficiency caused by sealing one by one.

[0016] 2. The sealing structure consists of a compression hole at the top of the storage tank, a return spring, a compression plate, a limiting groove, a limiting block, a sealing plate on the sealing cover, a first rubber strip, a downward pressure rod, and a second rubber strip on the inner wall of the storage tank. The downward pressure rod closes with the sealing cover and presses down on the compression plate. The compression plate slides and is limited in the limiting groove by the limiting block and compresses the return spring, causing the sealing plate to be engaged in the second rubber strip. The first and second rubber strips are in close contact, forming a multiple sealing effect, solving the problem of easy leakage in traditional sealing methods. The elasticity of the return spring keeps the sealing structure stable, and the limiting block and limiting groove prevent the compression plate from shifting. Combined with the elastic seal of the rubber strip, the sealing performance of the storage tank is ensured, preventing water sample leakage or contamination and ensuring the accuracy of test data.

[0027] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0028] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0029] Please see Figures 1-8The system includes a storage tank 1. A servo motor 17 and a ball bearing 16 are fixedly connected to the inner bottom wall of the storage tank 1. A drive shaft 18 is fixedly connected to the output end of the servo motor 17 and the inner ring of the ball bearing 16. An annular groove 20 is provided on the inner bottom wall of the storage tank 1. A thin-walled bearing 15 is fixedly connected to the outer ring of the inner wall of the annular groove 20. A stabilizing ring 19 is fixedly connected to the inner ring of the thin-walled bearing 15. A drive disk 12 is fixedly connected to the upper surface of the stabilizing ring 19 and the top end of the drive shaft 18. A rubber pad 11 is fixedly connected to the upper surface of the drive disk 12. Multiple storage tanks 13 are arranged above the drive disk 12. An installation disk 9 is fixedly connected to the outer surface of each storage tank 13. Each installation disk 9 is fixedly connected to the inner wall of the drive disk 12 by bolts through the rubber pad 11. A discharge pipe 10 is fixedly connected to the outer surface of each storage tank 13.

[0030] Specifically, the servo motor 17 drives the drive shaft 18 to rotate, and the drive shaft 18 achieves stable rotation through the ball bearing 16. At the same time, the drive shaft 18 drives the stabilizing ring 19 to rotate within the thin-walled bearing 15. The stabilizing ring 19 drives the drive disk 12 to rotate above the annular groove 20. The drive disk 12 fixes multiple storage tanks 13 through the rubber pad 11 and the mounting plate 9, so that the storage tanks 13 rotate synchronously with the drive disk 12. The discharge pipe 10 is used for water sample discharge, realizing the rotational positioning of the storage tanks 13. This solves the problem of low efficiency in batch operation of traditional independent sealing structures, facilitates the operation of specific storage tanks 13, and improves work efficiency.

[0031] Please see Figures 1-8 Each storage tank 13 has three compression holes 29 at its top. A return spring 25 is fixedly connected to the inner wall of each compression hole 29. A compression plate 24 is fixedly connected to the top of each return spring 25. Two symmetrical limiting grooves 30 are formed on the inner wall of each compression hole 29. A limiting block 23 is slidably connected inside each limiting groove 30. The outer surface of each compression plate 24 is fixedly connected to the side of the two limiting blocks 23 that are close to each other. A sealing element is movably hinged to the outer surface of each storage tank 13. Each sealing cover 8 has a sealing plate 21, a first rubber strip 26, and three pressing rods 27 fixedly connected to one side. Each storage tank 13 has a second rubber strip 28 fixedly connected to its inner wall. The outer surface of each sealing plate 21 is engaged with the inside of the second rubber strip 28. The bottom surface of each first rubber strip 26 is in contact with the upper surface of the second rubber strip 28. The bottom ends of the three pressing rods 27 on each sealing cover 8 are pressed against the upper surface of the compression plate 24. One of the sealing covers 8 is in an open / closed state.

[0032] Specifically, when the sealing cover 8 is closed, the sealing cover 8 drives the sealing plate 21, the first rubber strip 26, and the pressing rod 27 to move downwards. The pressing rod 27 presses down on the compression plate 24, and the compression plate 24 drives the limiting block 23 to slide within the limiting groove 30, thereby compressing the return spring 25. At the same time, the sealing plate 21 is inserted into the second rubber strip 28, and the first rubber strip 26 and the second rubber strip 28 are in close contact. The elastic force of the return spring 25 keeps the pressing rod 27 under pressure on the compression plate 24, so that the sealing plate 21 and the first rubber strip 26 and the second rubber strip 28 are in close cooperation, forming a multiple seal. This can effectively improve the sealing performance of the storage tank 13, solve the problem of easy leakage in traditional sealing methods, avoid water sample leakage or pollution, and ensure water sample quality.

[0033] Please see Figures 1-8 A fixed frame 14 is fixedly connected to the upper part of the inner wall of the storage box 1. An auxiliary closing pressure plate 7 is fixedly connected to the inner wall of the fixed frame 14. The upper surfaces of seven sealing covers 8 are in contact with the bottom surface of the auxiliary closing pressure plate 7, and another sealing cover 8 is located in the open area of ​​the auxiliary closing pressure plate 7.

[0034] Specifically, the auxiliary closing pressure plate 7 is fixed to the upper part of the inner wall of the storage tank 1 by the fixed frame 14. When the drive disc 12 drives the storage tank 13 to rotate, except for the sealing cover 8 located in the open area, the upper surface of the other seven sealing covers 8 contacts the bottom surface of the auxiliary closing pressure plate 7. The auxiliary closing pressure plate 7 applies pressure to these seven sealing covers 8 to keep them closed, while the sealing covers 8 located in the open area can be opened and closed normally. This structure can realize batch positioning of multiple sealing covers 8, solve the problem that traditional independent sealing structures need to be operated one by one, improve sealing efficiency, and facilitate the operation of a single storage tank 13.

[0035] Please see Figures 1-8 The upper surface of the drive disc 12 is fixedly connected to a support shaft 33, a plurality of first support rods 37 and a plurality of second support rods 36. The outer surface of the support shaft 33 is fixedly connected to two first annular plates 32. The outer surface of each first annular plate 32 is fixedly connected to a first annular rubber ring 34. The outer surface of each first annular rubber ring 34 is fixedly connected to a second annular plate 31. The outer surface of each second annular plate 31 is fixedly connected to a second annular rubber ring 35. The outer surface of each second annular rubber ring 35 is fixedly connected to a fixed flower rack 22. The outer surface of each storage tank 13 is fixedly connected to the inner wall of the fixed flower rack 22. The outer surface of each first support rod 37 is fixedly connected to the inner wall of the two first annular rubber rings 34. The outer surface of each second support rod 36 is fixedly connected to the inner wall of the two second annular rubber rings 35.

[0036] Specifically, the drive disc 12 increases the stability of the storage tank 13 through the support shaft 33, the first support rod 37, and the second support rod 36. The first annular plate 32 and the first annular rubber ring 34 on the support shaft 33 cooperate with the first support rod 37, and the second annular plate 31 and the second annular rubber ring 35 cooperate with the second support rod 36 to form a stable support structure. The fixed flower rack 22 is fixed to the second annular plate 31 through the second annular rubber ring 35. The storage tank 13 is fixed to the inner wall of the fixed flower rack 22. The first annular rubber ring 34 and the second annular rubber ring 35 play a buffering and shock absorption role, reducing the vibration of the storage tank 13 during rotation, which can improve the stability of the installation of the storage tank 13, solve the problem that the storage tank 13 is easy to shake during rotation, and avoid the storage tank 13 from failing to seal or shaking due to vibration.

[0037] Please see Figures 1-8 The bottom of the storage box 1 is fixedly connected with four feet 3. The front of the storage box 1 is fixedly connected with a start button 4. The start button 4 is electrically connected to the servo motor 17 through a wire. The front and left sides of the storage box 1 are respectively hinged with a sealing door 5 and a maintenance door 2. The upper surface of the storage box 1 is fixedly connected with a function box 6.

[0038] Specifically, the storage tank 1 is supported by feet 3 to ensure stability, the start button 4 controls the start and stop of the servo motor 17, the sealing door 5 seals the front of the storage tank 1 to protect the internal structure, the maintenance door 2 facilitates maintenance of the storage tank 1, and the function box 6 is fixed to the upper surface of the storage tank 1. Its internal space can be used to store recording paper and markers. When collecting water samples, staff can take out markers from the function box 6 to mark water sample information on the recording paper. After marking, the recording paper and markers can be put back into the function box 6. This provides dedicated storage space for recording paper and markers, solving the problem of traditional storage tanks lacking convenient storage structures for marking tools. It also prevents recording paper and markers from being lost or damaged during field operations, making it convenient for staff to mark water samples and record information, improving work efficiency and the accuracy of information recording. This solves the problems of inconvenient operation and difficult maintenance during device use, and improves the practicality and reliability of the device.

[0039] Working principle:

[0040] When water samples need to be stored, the servo motor 17 is started to drive the drive shaft 18 to rotate. The drive shaft 18 rotates stably through the ball bearing 16 and drives the stabilizing ring 19 to rotate within the thin-walled bearing 15, causing the drive disc 12 to rotate above the annular groove 20. Any one of the storage tanks 13 is rotated to the open area of ​​the auxiliary closing pressure plate 7. At this time, the sealing cover 8 of that storage tank 13 can be opened and closed. The sealing covers 8 of the other seven storage tanks 13 are held closed by the auxiliary closing pressure plate 7. The sealing cover 8 of that storage tank 13 is opened, and the water sample is poured in from the top. Then the sealing cover 8 is closed, and the sealing cover 8 drives the sealing... The sealing plate 21, the first rubber strip 26, and the pressing rod 27 move downwards. The pressing rod 27 presses down on the compression plate 24. The compression plate 24 drives the limiting block 23 to slide within the limiting groove 30 and compress the return spring 25. At the same time, the sealing plate 21 engages with the second rubber strip 28. The first rubber strip 26 and the second rubber strip 28 are in close contact to form a multiple seal, completing the water sample storage in the storage tank 13. Afterwards, the next storage tank 13 can be rotated to the open area by rotating the drive disc 12. The above operation is repeated, always keeping one of the eight storage tanks 13 in the open area for standby and seven for sample storage. To meet the requirement of simultaneous storage of multiple water samples, if it is necessary to seal eight storage tanks 13, the sealing caps 8 on the two storage tanks 13 in the open area must be rotated synchronously to the corresponding positions at the bottom of the open area of ​​the auxiliary closing pressure plate 7. At this time, the two sealing caps 8 are symmetrically distributed and are both pressed down to a semi-closed state by the auxiliary closing pressure plate 7. The limiting effect of the auxiliary closing pressure plate 7 on the seven sealing caps 8 avoids the tedious operation of sealing them one by one, improving storage efficiency. The support shaft 33, the first support rod 37, the second support rod 36 on the drive disc 12, the first annular plate 32, and the first annular rubber ring 34 are all connected to the drive disc 12. The second annular plate 31, the second annular rubber ring 35, and the fixed flower rack 22 work together to form a stable support structure. The first annular rubber ring 34 and the second annular rubber ring 35 dampen the vibration of the storage tank 13 during rotation. The pads 3 on the bottom of the storage box 1 support the stability. The sealing door 5 on the front closes the front of the storage box 1. The maintenance door 2 on the left side facilitates internal maintenance. The function box 6 on the upper surface can store recording paper and markers for marking water sample information. After marking, the paper and markers are put back into the function box 6 to ensure the convenience and accuracy of information recording. The discharge pipe 10 is used for the discharge of water samples.

For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
