Description

Technical Field

[0001] The invention relates to the technical field of hydrogeological exploration, in particular to a same-hole different-diameter pumping test device for hydraulic connection exploration of multiple aquifers. Background Art

[0002] In the field of hydrogeological exploration, in order to clarify the relationship between recharge, runoff and discharge among multiple aquifers, the same-hole different-diameter pumping test is often used: the target layer section is isolated and pumped in the same borehole, and its hydraulic connection is inverted by observing the water level response of each layer.

[0003] The currently commonly used isolation method is to set a water-absorbing and expanding water-stopping material, such as rubber or polymer water-absorbing and expanding resin, in the annular gap between the casing and the hole wall. During construction, the water-absorbing and expanding water-stopping ring is first put on the outside of the casing. After the casing is lowered to a predetermined depth, the water-stopping material expands when it comes into contact with water and radially squeezes the hole wall, thereby achieving the dual functions of positioning and water-stopping.

[0004] During the implementation of the above-mentioned technology, the inventors of the present application discovered that the elastic modulus and volume of the water-absorbing and expanding water-stopping material will undergo uncontrollable attenuation due to changes in groundwater mineralization, temperature and immersion time, resulting in a gradual decrease in the mechanical bite force between it and the hole wall, and then water-stopping failure and casing loosening. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides a same-hole different-diameter pumping test device for hydraulic connection exploration of multiple aquifers, which solves the problem in the existing technology that the elastic modulus and volume of the water-absorbing and swelling water-stopping material will undergo uncontrollable attenuation due to changes in groundwater mineralization, temperature and immersion time, resulting in a gradual decrease in the mechanical bite force between it and the hole wall, and then the water-stopping failure and casing loosening.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a same-hole different-diameter pumping test device for hydraulic connection exploration of multiple aquifers, comprising a housing and a detector, the detector being hoisted inside the housing, a water inlet being opened inside the upper side of the housing, and a snap mechanism being provided inside the housing;

[0007] The snap mechanism includes a fixing plate, the outside of the shell is fixedly connected to the inside of the shell, the outside of the fixing plate is clamped with an extrusion ring, the extrusion ring is arranged inside the shell, the inside of the extrusion ring is fixedly connected to a connecting pipe, the detector is hoisted inside the connecting pipe, a card slot is provided inside the extrusion ring, the outside of the fixing plate is slidingly connected to the inside of the card slot, the inside of the fixing plate is rotatably connected to a rotating column, the outside of the rotating column is fixedly connected to a card plate, a spring 1 is provided on the upper surface of the card plate, one end of the spring 1 is provided on the inner top wall of the fixing plate, a spring 2 is provided on the lower surface of the card plate, one end of the spring 2 is provided on the inner bottom wall of the fixing plate.

[0008] By adopting the above technical solution and providing a snap mechanism to replace the traditional water-absorbing and swelling water-stopping material, the problem of uncontrollable attenuation of elastic modulus and volume of water-absorbing and swelling materials in the prior art due to changes in groundwater salinity, temperature and immersion time, which in turn causes water-stopping failure and loosening of the casing, is effectively solved. The snap mechanism includes a fixed plate, an extrusion ring, a clamping plate, spring 1 and spring 2. The fixed plate cooperates with the clamping groove inside the extrusion ring to guide the installation trajectory of the extrusion ring inside the shell and avoid component misalignment. When the extrusion ring is installed, it squeezes the clamping plate to stretch spring 1 and compress spring 2. When the extrusion ring slides to the top of the fixed plate, spring 1 and spring 2 reset and drive the clamping plate to clamp inside the extrusion ring, achieving a stable fixation of the extrusion ring and the casing. The snap mechanism is not affected by environmental factors such as moisture, and the fixing force is stable and controllable. It can reliably fix casings or filter tubes of different diameters to the hole wall for a long time and achieve interlayer water-stopping, ensuring the smooth progress of the same-hole different-diameter pumping test.

[0009] Preferably, the snap mechanism further includes a rotating rod, a water-permeable hole, a gear, a rack, a connecting rod, a slide groove, a mounting plate, a clamping block and a spring.

[0010] Preferably, the outer lower side of the rotating rod is rotatably connected to the inside of the extrusion ring, a water-permeable hole is opened inside the extrusion ring, the outer lower side of the rotating rod is fixedly connected to a gear, the outer side of the gear is rotatably connected to the inside of the extrusion ring, the tooth end of the gear is meshed with a rack, the outer side of the rack is slidably connected to the inside of the extrusion ring, and the outer side of the rack is fixedly connected to a connecting rod.

[0033] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1

[0035] Please see the attached Figure 1 -Attached Figure 5 The embodiment of the present invention provides a same-hole different-diameter pumping test device for hydraulic connection exploration of multiple aquifers, comprising a housing 1 and a detector 2. The detector 2 is hoisted inside the housing 1. A water inlet 3 is provided inside the upper side of the housing 1. A snap mechanism is provided inside the housing 1.

[0036] The snap mechanism includes a fixing plate 4, the outside of the shell 1 is fixedly connected to the inside of the shell 1, the outside of the fixing plate 4 is clamped with an extrusion ring 5, the extrusion ring 5 is arranged inside the shell 1, the inside of the extrusion ring 5 is fixedly connected to a connecting pipe 6, the detector 2 is hoisted inside the connecting pipe 6, a card slot 7 is provided inside the extrusion ring 5, the outside of the fixing plate 4 is slidingly connected to the inside of the card slot 7, the inside of the fixing plate 4 is rotatably connected to a rotating column 8, the outside of the rotating column 8 is fixedly connected to a card plate 10, a spring 19 is provided on the upper surface of the card plate 10, one end of the spring 19 is provided on the inner top wall of the fixing plate 4, a spring 2 11 is provided on the lower surface of the card plate 10, one end of the spring 2 11 is provided on the inner bottom wall of the fixing plate 4.

[0037] Specifically, the detector 2 is hoisted on the shell 1 to facilitate monitoring of water level changes in different aquifers. A water inlet 3 is provided inside the upper side of the shell 1. Water from the upper aquifer can flow into the interior of the shell 1 through the water inlet 3. The squeezing ring 5 is positioned in the shell 1 by snapping together with the fixing plate 4. The connecting pipe 6 is a channel for water flow in the lower aquifer. Detectors 2 are respectively provided inside the shell 1 and the connecting pipe 6. The detector 2 detects the upper water in the shell 1 and the lower water in the connecting pipe 6. The lower layer of the squeezing ring 5 is a rubber ring used to adapt to changes in the diameter of the shell 1 and prevent water leakage. When the squeezing ring 5 and the connecting pipe 6 need to be installed, the fixing plate 4 slides along the card slot 7 to guide the squeezing ring 5 in the shell 1 The moving trajectory inside avoids dislocation of components during installation. The rotating column 8 provides a rotating fulcrum for the card plate 10, so that the card plate 10 can rotate. When the extrusion ring 5 is installed, the card plate 10 will be squeezed, so that the spring 1 9 will be stretched and the spring 2 11 will be compressed. When the extrusion ring 5 slides to the top of the fixed plate 4, the spring 1 9 and the spring 2 11 will be reset, driving the card plate 10 to be clamped inside the extrusion ring 5, so as to achieve a firm fixation of the extrusion ring 5 and the shell 1. The snap mechanism is not affected by moisture, and the fixing force is stable and controllable, which avoids the problem of fixation failure or device damage caused by environmental changes of the water-absorbing and expanding material, ensures the firmness and stability of the connection between the extrusion ring 5 and the shell 1, and improves the reliability of the hydraulic connection exploration data of multiple aquifers.

[0038] Please see the attached Figure 6 and attached Figure 9 A filter plate 26 is fixedly connected to the bottom end of the connecting pipe 6, and a filter hole 22 is opened inside the filter plate 26; a mounting column 23 is rotatably connected to the inside of the filter plate 26, and a fan blade 24 is fixedly connected to the top of the mounting column 23; a scraper 25 is fixedly connected to the outside of the mounting column 23, and the lower surface of the scraper 25 is arranged on the upper surface of the filter plate 26.

[0039] Specifically, when the lower layer of water flows into the connecting pipe 6, the water will first pass through the filter plate 26. The filter holes 22 can preliminarily intercept and filter the mud and large particles in the water, preventing the impurities from entering the inside of the connecting pipe 6, solving the problem of inaccurate data caused by direct entry of impurities in the traditional device. When the water flows upward through the filter holes 22, the water will impact the fan blades 24, driving the fan blades 24 to rotate, thereby causing the mounting column 23 to rotate around the filter plate 26. The outside of the mounting column 23 is fixedly connected to the scraper 25. When the mounting column 23 rotates, it will synchronously drive the scraper 25 to rotate on the upper surface of the filter plate 26, continuously scraping the fine impurities attached to the surface of the filter plate 26, preventing these impurities from clogging the filter holes 22, ensuring that the water can smoothly pass through the filter plate 26 into the connecting pipe 6, solving the problem of poor water flow and distortion of detection data due to the accumulation of impurities in the traditional filtering structure, and ensuring the accuracy of water level detection in the pumping test.

[0040] Please see the attached Figure 10 A mounting groove 27 is provided inside the mounting block 21 , and a heat dissipation fin 28 is provided outside one side of the mounting block 21 .

[0041] Specifically, a mounting groove 27 is provided inside the mounting block 21, and the detector 2 is hoisted in the mounting groove 27. The mounting groove 27 provides an installation space for the detector 2 to ensure that the detector 2 is always in the preset detection position to avoid inaccurate detection points due to position offset. The detector 2 will continue to generate heat when working, especially during a long water pumping test, when heat is easy to accumulate. The heat dissipation fins 28 can quickly transfer the heat of the mounting block 21 and the internal detector 2 to the surrounding air by increasing the contact area with the external environment, thereby effectively reducing the operating temperature of the detector 2 and avoiding its performance degradation, sensitivity reduction or even failure due to high temperature.

[0042] Working principle: First, drill an exploration hole in the ground and place the shell 1 in the hole, then install the extrusion ring 5 and the connecting pipe 6 inside the shell 1, and the fixed plate 4 inside the shell 1 cooperates with the card slot 7 of the extrusion ring 5. During the installation process, continue to squeeze the extrusion ring 5. At this time, the fixed plate 4 will slide inside the card slot 7 and squeeze the card plate 10 at the same time. When the card plate 10 is squeezed, it will drive the spring 1 9 to stretch. When the extrusion ring 5 slides to the top of the fixed plate 4, the card plate 10 is clamped to the inside of the extrusion ring 5 under the action of spring 1 9 and spring 2 11, so that the extrusion ring 5 and the shell 1 are fixed. At this time, the upper water will flow into the inside of the shell 1 through the water inlet 3, and the lower water will flow into the inside of the connecting pipe 6. Then the detector 2 is hoisted inside the shell 1 and the connecting pipe 6 to detect water level changes.

[0043] Secondly, a water pumping test is carried out. The upper water flows into the device through the water inlet 3 of the outer shell 1. When the lower water flows into the inside of the connecting pipe 6, the filter hole 22 first performs preliminary filtering on the mud and impurities in the water flow to prevent large particles from entering the connecting pipe 6 and affecting the operation of the detector 2. At the same time, the water flow impacts the fan blades 24 to drive the mounting column 23 to rotate. The scraper 25 on the mounting column 23 rotates with it, continuously scraping the upper surface of the filter plate 26 to remove attached fine impurities and avoid clogging of the filter hole 22. This solves the problem of poor water flow and distorted detection data caused by impurity blockage in traditional devices.

[0044] The detector 2 is hoisted in the mounting slot 27 of the mounting block 21. The heat dissipation fins 28 on one side of the mounting block 21 can quickly conduct the heat generated by the detector 2 during operation to the external environment, avoiding the performance degradation or failure of the detector 2 due to excessive temperature. This solves the problem in traditional devices that the detector 2 is overheated due to long-term operation, affecting its service life and detection accuracy, and ensures that the detector 2 maintains a stable operating state throughout the water pumping test.

[0045] Example 2

[0046] The buckle of the first embodiment fixes the extrusion ring 5 to the housing 1 by means of the fixing plate 4, the card slot 7, the card plate 10, the spring 1 9 and the spring 2 11. Although the connection can be completed, it may become loose in complex environments such as high water pressure due to insufficient clamping force relying solely on the spring reset. The buckle of the second embodiment drives the gear 14 to engage the rack 15 by rotating the rotating rod 12, so that the connecting rod 16 pushes the clamping block 19 to be tightly clamped to the inside of the housing 1 under the elastic force of the spring 3 20, solving the problem that the buckle in the first embodiment may not be tight.

[0047] Please see the attached Figure 7 and attached Figure 8 The buckle mechanism also includes a rotating rod 12, a water-permeable hole 13, a gear 14, a rack 15, a connecting rod 16, a slide 17, a mounting plate 18, a block 19 and a spring 20; the outer portion of the lower side of the rotating rod 12 is rotatably connected to the interior of the extrusion ring 5, the interior of the extrusion ring 5 is provided with a water-permeable hole 13, the outer portion of the lower side of the rotating rod 12 is fixedly connected to the gear 14, the outer portion of the gear 14 is rotatably connected to the interior of the extrusion ring 5, the tooth end of the gear 14 is meshed with the rack 15, and the outer portion of the rack 15 is slidably connected Inside the extrusion ring 5, a connecting rod 16 is fixedly connected to the outside of the rack 15; a slide groove 17 is opened inside the extrusion ring 5, one end of the connecting rod 16 is fixedly connected to a clamping block 19, the outside of the clamping block 19 is slidably connected to the inside of the slide groove 17 and clamped to the inside of the shell 1, and the inside of the extrusion ring 5 is fixedly connected to a mounting plate 18; the outside of the connecting rod 16 is slidably connected to the inside of the mounting plate 18, and a spring three 20 is provided on the outside of the clamping block 19, and one end of the spring three 20 is provided on the outside of the mounting plate 18.

[0048] Specifically, when the extrusion ring 5 needs to be installed, the extrusion ring 5 and the connecting pipe 6 are installed inside the shell 1, and then the rotating rod 12 is manually rotated, and the gear 14 fixed on the lower side rotates inside the extrusion ring 5. The rotation of the gear 14 drives the rack 15 to slide inside the extrusion ring 5, and the rack 15 drives the block 19 to slide along the slide groove 17 through the connecting rod 16. At this time, the spring three 20 outside the block 19 is compressed, and the connecting rod 16 slides inside the mounting plate 18. When the block 19 is aligned with the engaging position inside the shell 1, the rotating rod 12 is released, and the spring three 20 resets and pushes the block 19 to engage inside the shell 1, completing the fixation of the extrusion ring 5 and the shell 1. The water permeable hole 13 inside the extrusion ring 5 can ensure the normal passage of water.

[0049] During disassembly, the rotating rod 12 is rotated in the opposite direction, and the gear 14 drives the rack 15 to slide in the opposite direction. The rotation of the gear 14 drives the rack 15 to slide inside the extrusion ring 5. The rack 15 drives the block 19 to slide along the slide groove 17 through the connecting rod 16. At this time, the spring 20 outside the block 19 is compressed, and the connecting rod 16 slides inside the mounting plate 18. Then the rotating rod 12 is manually pulled to disengage the block 19 from the engagement of the housing 1, and finally the extrusion ring 5 is removed from the housing 1.

[0050] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
