Description

Technical Field

[0001] This utility model belongs to the field of hydrogeological exploration technology, specifically relating to a water sample storage device for hydrogeological exploration. Background Technology

[0002] Water sampling and storage are crucial for obtaining accurate hydrogeological information. Accurate water sample analysis results are essential for understanding groundwater resources, assessing water pollution levels, and developing reasonable water resource protection and utilization strategies. However, when collecting water samples from different water bodies, most devices struggle to effectively prevent interference between different samples. Traditional devices often lack proper structural design and cannot strictly differentiate and control the sampling process. This leads to subsequent samples being easily contaminated by residual pollutants from previous samples, severely affecting the accuracy of water sample testing and causing results that do not accurately reflect the actual water quality of each water body. Furthermore, if the storage device is not completely filled with water during sampling, air residue can remain inside. For oxygen-sensitive samples, such as those containing sulfides, this reaction can alter the water sample composition, easily leading to biased analytical results. Utility Model Content

[0003] This invention provides a water sample storage device for hydrogeological exploration, which solves the problem of existing water sample storage devices causing interference between different water bodies when collecting samples from different water bodies.

[0004] This utility model provides the following technical solution: It includes an outer casing, an mounting plate installed on the top of the outer casing, a vertical rod slidably connected to the center of the mounting plate, several fixing sleeves installed on the outer side of the vertical rod, a storage tube slidably connected to the inner wall of the fixing sleeve, a sliding plate slidably connected to the inner wall of the storage tube, the sliding plate and the inner wall of the storage tube being connected by a spring, a sealing plate threaded to the top of the storage tube, a one-way valve installed on the sealing plate, several mating holes matching the fixing sleeves on the mounting plate, a water inlet hole offset from the mating holes on the mounting plate, a rotating plate rotatably connected to the mounting plate, a clearance hole corresponding to the mating holes on the rotating plate, and a water pump installed on the rotating plate.

[0017] Please see Figures 1-4The present invention provides the following technical solution: it includes an outer casing 1, an mounting plate 2 installed on the top of the outer casing 1, a vertical rod 21 slidably connected to the center of the mounting plate 2, several fixing sleeves 23 installed on the outside of the vertical rod 21, a storage tube 24 slidably connected to the inner wall of the fixing sleeve 23, a sliding plate 241 slidably connected to the inner wall of the storage tube 24, the sliding plate 241 and the inner wall of the storage tube 24 are connected by a spring 243, a sealing plate 25 is threadedly connected to the top of the storage tube 24, a one-way valve 26 is installed on the sealing plate 25, several mating holes 27 matching the fixing sleeves 23 are opened on the mounting plate 2, a water inlet hole 28 misaligned with the mating holes 27 is opened on the mounting plate 2, a rotating plate 31 is rotatably connected to the mounting plate 2, a clearance hole 32 corresponding to the mating holes 27 is opened on the rotating plate 31, and a water pump 33 is installed on the rotating plate 31.

[0018] In this implementation scheme: the outer casing 1 serves as the carrier of the supporting device. The mounting plate 2 installed on the top of the outer casing 1 is used to mount the upright 21. The upright 21 slides at the center of the mounting plate 2, allowing several fixing sleeves 23 mounted on the outside of the mounting plate 2 to be installed inside the outer casing 1. At this time, the fixing sleeves 23 can install the storage tube 24, allowing the storage tube 24 to slide against the inner wall of the corresponding mating hole 27 on the mounting plate 2. When the storage tube 24 is inside the outer casing 1, its top is within the mating hole 27. The sealing plate 25, threadedly connected to the top of the storage tube 24, can then seal the storage tube 24, ensuring proper sealing. The storage tube 24 ensures the storage of water samples after collection. During water sample collection, the sealing plate 25 is separated from the top of the storage tube 24. After separation, the rotating plate 31 rotates to the center position at the top of the mounting plate 2. At this point, the water pump 33 can rotate to the position of the removed sealing plate 25, ensuring that the outlet of the water pump 33 aligns with the docking hole 27. This allows the water pump 33 to extract water from the water area and collect it, then deposit it into one of the storage tubes 24. After collection, the rotating plate 31 rotates, causing the water pump 33 to be misaligned with the docking hole 27, aligning the clearance hole 32 with the docking hole 27, thus ensuring the sealing plate 24 is properly sealed. The sealing plate 25 seals the sample. When collecting water samples from the next water body, the rotating plate 31 rotates, aligning the water pump 33 with the inlet 28 to pump water from the next water body. After pumping a certain amount of water from that water body to flush the water pump 33 pipeline, the clearance hole 32 aligns with the next storage pipe 24, separating the sealing plate 25. The water pump 33 then resumes its corresponding water injection operation. This device prevents the next water body from being affected by the previous water body during sampling and storage, thus preventing mixing and ensuring accurate sample detection. When water enters the storage tube 24, the sliding plate 241, which is slidably connected to the inner wall of the storage tube 24, is supported by the spring 243. This allows the sliding plate 241 to push the water, enabling some water to overflow the top of the storage tube 24. Simultaneously, when the sealing plate 25 is installed, it compresses the water at the top, allowing excess water to drain through the one-way valve 26. This ensures that the storage tube 24 is filled with the collected water sample. The sealing plate 25 prevents the water in the storage tube 24 from coming into contact with air, thus preventing oxidation, carbon dioxide release, or other gas exchange reactions. For some oxygen-sensitive water samples, such as those containing sulfides, sealed storage can prevent the sulfides from being oxidized to sulfates, which would affect the analytical results.

[0019] The inner wall of the outer casing 1 is fixedly connected to a support rod 211 for supporting the bottom of the upright 21. The outer wall of the upright 21 is fixedly connected to a support frame 22 connected to the bottom of the fixing sleeve 23. The support rod 211 fixedly connected to the inner wall of the outer casing 1 is used to support the bottom of the upright 21, so that the top of the storage tube 24 can be supported on the inner wall of the docking hole 27. At the same time, it can pull the mounting plate 2 up, so that the storage tube 24 is pushed by the fixing sleeve 23, so that the top of the storage tube 24 can be pushed out of the top position of the mounting plate 2, making it easy to remove the storage tube 24. The support frame 22 is used to support the fixing sleeve 23.

[0020] A slide rod 242 is fixedly connected to the inner wall of the storage tube 24, and a spring 243 is sleeved on the outer wall of the slide rod 242. The slide rod 242 is slidably connected to the slide plate 241. The slide rod 242 fixedly connected to the inner wall of the storage tube 24 can limit the up and down sliding of the slide plate 241, and at the same time limit the installation position of the spring 243, so as to ensure that the slide plate 241 slides vertically up and down.

[0021] A rotating bracket 251 is installed at the top of the sealing plate 25, and a threaded ring 252 is fixedly connected to the bottom of the sealing plate 25. An annular groove matching the threaded ring 252 is opened at the top of the storage tube 24. The rotating bracket 251 fixedly connected to the top of the sealing plate 25 facilitates the rotation and adjustment of the sealing plate 25. The threaded ring 252 fixedly connected to the bottom of the sealing plate 25 is used to connect with the annular groove opened at the top of the storage tube 24, so that the sealing plate 25 is sealed at the top of the storage tube 24.

[0022] A locking post 341 is installed on the top of the mounting plate 2. A mounting ring 3 is rotatably connected to the outer wall of the rotating plate 31. A locking ring 34 corresponding to the locking post 341 is fixedly connected to the outer wall of the mounting ring 3. The locking post 341 installed on the top of the mounting plate 2 is used to enable the locking ring 34 fixedly connected to the outer wall of the mounting ring 3 to engage with it. After the locking ring 34 is fixed, the position of the mounting ring 3 is fixed, so that the mounting ring 3 is stably installed on the mounting plate 2. This allows the rotating plate 31 to slide stably on the inner wall of the mounting ring 3, and the position of the water pump 33 can be adjusted.

[0023] A sealing ring 271 is slidably connected to the inner wall of the docking hole 27 and fits against the outer wall of the storage tube 24. The sealing ring 271 is used to seal the storage tube 24 when it is in the inner wall of the docking hole 27, so as to ensure that the water pump 33 can draw water and inject it into the storage tube 24. At the same time, when the fixing sleeve 23 pushes the storage tube 24 upward, its sliding will not limit the position adjustment of the fixing sleeve 23.

[0024] The working principle and usage process of this utility model are as follows: the retaining ring 34 is engaged and fixed with the retaining post 341 at the top of the mounting plate 2, ensuring that the rotating plate 31 can rotate stably on the inner wall of the mounting ring 3.

[0025] First water sample collection: Separate the sealing plate 25 from the storage tube 24, rotate the rotating plate 31 to align the outlet of the water pump 33 with the docking hole 27, start the water pump 33 to draw the first water sample from the water area and inject it into one of the storage tubes 24. After the collection is completed, rotate the rotating plate 31 to misalign the water pump 33 with the docking hole 27, so that the clearance hole 32 aligns with the docking hole 27, and seal the storage tube 24 with the sealing plate 25.

[0026] Subsequent water sample collection: Rotate the rotating plate 31 to align the water pump 33 with the water inlet 28, pump water from the next water area to flush the water pump 33 pipeline, then rotate the rotating plate 31 to align the clearance hole 32 with the next storage pipe 24, separate the sealing plate 25, and start the water pump 33 to inject the water sample from the next water area into the storage pipe 24.

[0027] Water sample storage: After the water sample is injected into the storage tube 24, the slide plate 241 is supported by the spring 243 and pushes the water. Some of the water overflows the top of the storage tube 24. The sealing plate 25 is installed, and the excess water is discharged through the one-way valve 26 to ensure that the storage tube 24 is full of water sample and sealed to prevent the water sample from reacting with air.

[0028] Water sample removal: When it is necessary to remove the water sample, pull up the mounting plate 2, the support frame 22 drives the fixing sleeve 23 to push the storage tube 24, so that the top of the storage tube 24 is pushed out of the top position of the mounting plate 2, making it easy to remove the storage tube 24.
