Description

Technical Field

[0001] This utility model relates to a water extraction device inside a borehole, belonging to the technical field of groundwater collection devices in exploration engineering. Background Technology

[0002] Geotechnical engineering investigation refers to the activity of investigating, analyzing, and evaluating the geological and environmental characteristics and geotechnical engineering conditions of a construction site according to the requirements of a construction project, and preparing investigation documents. Poor investigation work will directly affect the success or failure of the project. The main tasks of geotechnical investigation include identifying the type, quality, depth, distribution, and changes of groundwater. Drilling is the most widely used exploration method when investigating groundwater. Drilling provides a direct understanding of the groundwater level and soil properties. The main method involves drilling boreholes on the ground to collect water samples at static water levels. These samples are then used for laboratory testing to determine water quality and analyze the corrosiveness of water to concrete structures, reinforcing steel, and steel structures.

[0003] In actual exploration projects, one method for obtaining water samples from boreholes is to use a miniature water pump. However, this method makes the sampling process complex, requires a lot of equipment, and necessitates a generator for pumping. Furthermore, obtaining groundwater samples is typically an outdoor operation, which is inconvenient. Another method is to use readily available materials, such as mineral water bottles, as simple water collection devices. These are generally rudimentary, and require placing stones or scrap iron at the bottom as counterweights. However, these stones and scrap iron can interfere with water quality testing, affecting its accuracy. Moreover, this method cannot avoid the influence of suspended solids and coarse particles within the borehole on water quality during the sampling process. Using plastic bottles is simple, but inefficient, yielding only a small amount of water each time. It also mixes with a large amount of soil, making filtration difficult, resulting in turbid water. Additionally, the lightweight plastic bottles easily float in the borehole water and are not easy to fill.

[0004] Groundwater level measurement is a crucial component of hydrogeological assessment, while water quality testing is essential for evaluating groundwater corrosivity, as the level of corrosivity significantly impacts submerged structures. Therefore, existing technologies have proposed water sampling devices that combine level detection and sampling, such as the groundwater sampling and measurement device disclosed in Chinese Utility Model Patent Application No. 202221774215.5. This utility model addresses the problem of devices that cannot integrate water sampling and level measurement, thus saving time and manpower, by incorporating a measuring rope, a water sampling device, and a sampling water inlet. Furthermore, the inclusion of a sealing gasket at the water inlet prevents leakage when water enters the sampling device and comes into contact with the sealing ball due to gravity. However, this device is too rudimentary and impractical, requiring further improvement. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a water extraction device for boreholes.

[0006] The technical solution adopted by this utility model is as follows: a water extraction device for borehole is designed, which includes a storage mechanism, a measuring rope and a water extractor. The storage mechanism includes a storage container and a mounting frame set on the storage container. The storage container is provided with a storage cavity for accommodating the water extractor. The water extractor is inserted into the storage cavity. The mounting frame is provided with a roller. The roller is rotatably arranged. One end of the measuring rope is wound around the roller, and the other end is tied to the water extractor. The measuring rope is provided with a measuring scale.

[0007] The water collector includes a counterweight and a water storage cylinder. The water storage cylinder is open at both ends. The counterweight is located at the lower opening of the water storage cylinder. The measuring rope passes through the water storage cylinder and is connected to the counterweight. A limit knot is provided on the measuring rope. The water storage cylinder can slide along the measuring rope between the limit knot and the counterweight. When it slides to the limit knot, it is blocked by the limit knot. When it slides to the counterweight, it is blocked by the counterweight. At the same time, the counterweight blocks the lower port of the water storage cylinder.

[0008] Furthermore, the storage cavity is inclined upwards, and a buffer layer is filled around the perimeter of the storage cavity.

[0009] Furthermore, one end of the roller extends out of the mounting bracket, and a rotating handle is provided at the end of the roller extending out of the mounting bracket. The rotating handle is located on the side of the storage cavity insertion port.

[0010] Furthermore, filter layers are provided at both ends of the water storage cylinder, and the filter layers are detachably installed. The filter layers are provided with through holes that allow the measuring rope to pass through and slide.

[0011] Furthermore, the water storage cylinder includes a cylinder body and an end head. The two ends of the cylinder body are respectively threaded to the end head. The two ends of the cylinder body are respectively provided with steps. The filter layer is placed on the steps and pressed by the end head.

[0012] Furthermore, the counterweight includes a conical portion and a ball-sealing portion disposed on the conical portion. A guide nozzle is provided at the end of the conical portion, and an arc-shaped cavity is provided at the end of the guide nozzle for receiving the ball-sealing portion.

[0013] Furthermore, a neck is provided between the ball-shaped part and the conical part, and a sealing sleeve is wrapped around the ball-shaped part, with openings at both ends of the sealing sleeve.

[0014] Furthermore, a rope channel is provided through the spherical and conical parts of the counterweight block, and the measuring rope passes through the rope channel and is then knotted.

[0015] Furthermore, the arc-shaped cavity can accommodate at least half of the sphere's body from the sealing section.

[0016] Furthermore, the water dispenser is made of transparent material, or the water storage tank is equipped with a transparent observation window, and a thermometer is also installed inside the water storage tank.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention, through its storage mechanism combined with a measuring rope and water sampler, facilitates storage, transfer, and retrieval during actual surveying projects. It is particularly suitable for complex outdoor working environments. The combination of the measuring rope and water sampler integrates sampling and measurement. The sampling process is relatively simple, requires minimal equipment, allows for large water collection volumes per sample, and minimizes interference with water quality testing, resulting in high accuracy. The overall structure of this invention is rationally designed and easy to use in practice.

[0019] This invention is simple to operate, capable of measuring water levels, collecting relatively clear groundwater, and measuring the groundwater temperature in the borehole in real time, providing real-time temperature information for specialized indoor water quality analysis and corrosion testing. While collecting groundwater, the water level in the borehole can be measured. The use of this equipment can effectively improve water extraction quality and has excellent application prospects in exploration. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Example 1

[0028] like Figures 1-3 As shown, a water-collecting device for boreholes includes a storage mechanism, a measuring rope 1, and a water collector 2. The storage mechanism includes a storage container 3 and a mounting frame 4 mounted on the storage container 3. The storage container 3 is designed as an isosceles trapezoid with a low center of gravity for stable placement. The mounting frame 4 is designed as a gantry structure, which is simple in structure and facilitates the placement of rollers 6 and easy for users to carry. A rubber anti-slip sleeve (not shown in the figure) can also be installed on the crossbar in the middle of the gantry for greater comfort when carrying the water-collecting device. The storage container 3 is provided with a storage cavity 5 for accommodating the water dispenser 2. The water dispenser 2 is inserted into the storage cavity 5 to avoid damage to the equipment and affect normal use, thus providing good protection for the equipment and facilitating retrieval and storage. The mounting frame 4 is provided with a roller 6, which is rotatable. One end of the measuring rope 1 is wound around the roller 6, and the other end is tied to the water dispenser 2. The structure is simple and easy to operate. The measuring rope 1 is provided with a measuring scale (not shown in the attached figure; a conventional measuring scale setting method can be used on the surface of the measuring rope 1).

[0029] The water sampler 2 includes a counterweight 7 (the counterweight 7 mainly facilitates the water sampler 2 to enter the groundwater body in the borehole more smoothly under the action of gravity, avoiding excessive buoyancy and affecting the groundwater collection efficiency; it can be a metal block with a surface coated with an anti-corrosion layer) and a water storage cylinder 8 (used to store the water sample to be obtained). The water storage cylinder 8 is open at both ends for easy water intake and pouring out to transfer the water sample after water collection. The counterweight 7 is set at the lower opening of the water storage cylinder 8. The measuring rope 1 passes through the water storage cylinder 8 and is connected to the counterweight 7. The measuring rope 1 is provided with a limiting knot 9 (or a baffle or circular baffle, etc.). The water storage cylinder 8 can slide along the measuring rope 1 between the limiting knot 9 and the counterweight 7. When it slides to the limiting knot 9, it is blocked by the limiting knot 9 (but the limiting knot 9 will not block the upper opening of the water storage cylinder 8, so that water can flow in the water storage cylinder 8 for rapid water intake), thus stopping the upward sliding. When it slides to the counterweight 7, it is blocked by the counterweight 7, thus stopping the downward sliding. At the same time, the counterweight 7 blocks the lower port of the water storage cylinder 8.

[0030] When water needs to be extracted from inside the borehole, the water extractor 2 is taken out from the storage chamber 5. The measuring rope 1 is held by hand, and the water extractor 2 is lowered down the borehole. After reaching the static water level inside the borehole, the counterweight 7 continues to descend, and the water storage cylinder 8 contacts the water surface. The water storage cylinder 8, under the buoyancy of the water, begins to slide upwards along the measuring rope 1. It stops sliding after reaching the limit knot 9. Then, the counterweight 7 drives the water storage cylinder 8 to continue descending, and water enters the water storage cylinder 8. The operator estimates when the water storage cylinder 8 is full (this can be judged by experience, by the weight of the water extractor 2 when it is lifted, or by listening to the sound of the counterweight 7 entering the water). Time-based judgment. For example: When using the device, place the entire device inside the borehole, and slowly lower the device into the borehole by pulling the graduated measuring rope until it touches the water surface. At this point, due to buoyancy, the device will become noticeably lighter, and you may even hear a water sound. Then, slowly lower the device about 15-20cm to complete the water collection. Afterward, pull the device out of the borehole. Then, pull the water sampler 2 upward. At this time, the water storage cylinder 8 containing the water sample will slide to the counterweight 7, which will block the lower end of the water storage cylinder 8. After pulling the water sampler 2 out of the borehole, transfer the water sample from the water storage cylinder 8. After removing the device, you can read the numbers on the wet part of the measuring rope and calculate the water level depth.

[0031] Example 2

[0032] This embodiment is a further optimization and refinement of the storage mechanism structure based on Embodiment 1, specifically as follows:

[0033] The storage cavity 5 of the storage container 3 is tilted upwards, so that the water dispenser 2 can be placed and retrieved quickly and securely, avoiding it from falling out easily. The storage container 3 is filled with a buffer layer 10 around the storage cavity 5, such as foam plastic, to protect the water dispenser 2. In particular, the water dispensing device is mainly used outdoors in a complex environment, so it is even more necessary to protect important components.

[0034] In this embodiment, one end of the roller 6 extends out of the mounting frame 4, and a rotating handle 11 is provided at the end of the roller 6 extending out of the mounting frame 4 to facilitate the retrieval of the measuring rope 1 and the retraction of the water dispenser 2. The rotating handle 11 is located on the side of the insertion port of the storage cavity 5 for easy operation.

[0035] Example 3

[0036] This embodiment is a further optimization and refinement of the structure of the water storage cylinder 8 based on embodiment 2, specifically as follows:

[0037] The water storage cylinder 8 is provided with filter layers 12 at both ends (which can be simple filter structures, such as a metal circular plate with dense filter holes). These filter layers can filter most of the suspended solids and coarse particles in the borehole, preventing the collected groundwater from becoming excessively turbid and affecting the accuracy of the test. The filter layers 12 are detachable, making them easy to clean, replace and maintain. The filter layers 12 are provided with through holes that allow the measuring rope 1 to pass through and slide.

[0038] In this embodiment, the water storage cylinder 8 includes a cylinder body 13 and an end 14. The two ends of the cylinder body 13 are respectively threaded to the end 14 for easy disassembly and assembly. The two ends of the cylinder body 13 are respectively provided with steps 15. The filter layer 12 is placed on the steps 15 and pressed by the end 14. This is a way of detachable installation of the filter layer 12. Other detachable installation methods can also be used, such as fixing with screws.

[0039] Example 4

[0040] This embodiment is a further optimization and refinement of the structure of counterweight 7 based on embodiment 3, specifically as follows:

[0041] The counterweight 7 includes a conical portion 16 and a sealing ball portion 17 disposed on the conical portion 16. A guide nozzle 18 is provided on the end 14 to facilitate the guidance of water into and out of the water storage cylinder 8. An arc-shaped cavity 19 is provided at the end of the guide nozzle 18. The arc-shaped cavity 19 is used to receive the sealing ball portion 17. When the sealing ball portion 17 of the counterweight 7 blocks the lower port of the water storage cylinder 8, the sealing ball portion 17 enters the arc-shaped cavity 19, with a sufficiently large contact area to improve the sealing effect.

[0042] In this embodiment, a neck 20 is provided between the ball-sealing part 17 and the conical part 16 to facilitate the installation of the ball-sealing part 17 and the sealing sleeve 22. The three are welded together or integrally formed. The ball-sealing part 17 is wrapped with the sealing sleeve 22, which can be a rubber sleeve, to increase the sealing effect of the ball-sealing part 17 on the port of the water storage cylinder 8. The sealing sleeve 22 has openings at both ends for easy installation.

[0043] Example 5

[0044] This embodiment is a further optimization and refinement of the structure of counterweight 7 based on embodiment 4, specifically as follows:

[0045] The counterweight 7 has a rope channel running through the ball-sealing part 17 and the cone-shaped part 16 for easy installation. The measuring rope 1 passes through the rope channel and is knotted, making the connection convenient and reliable. Alternatively, a lug can be provided at the upper end of the ball-sealing part 17 to connect the measuring rope 1.

[0046] In this embodiment, the arc-shaped cavity 19 can accommodate at least half of the spherical body of the sealing part 17 (including the sealing sleeve 22), ensuring sufficient sealing area.

[0047] Example 6

[0048] This embodiment is a further optimization and refinement of the structure of the water dispenser 2 based on embodiment 5, specifically as follows:

[0049] The water storage cylinder 8 is made of transparent material, such as glass or plastic, or the water storage cylinder 8 is provided with a transparent observation window (not shown in the attached figure). The observation window needs to be set along the axial direction of the body 13 of the water storage cylinder 8 to facilitate observation of the state of the collected groundwater. The water storage cylinder 8 is also equipped with a thermometer 21, which can measure the groundwater temperature in the borehole in a timely manner, providing real-time water temperature information for special indoor water quality analysis tests and corrosion tests.
