Description

Technical Field

[0001] This invention relates to the technical field of drilling and sampling in hydrogeological exploration, specifically to a drilling and sampling device for hydrogeological exploration. Background Technology

[0002] Drilling and sampling in hydrogeological and environmental geological exploration is a crucial step in hydrogeological, engineering geological, and environmental geological investigations. It aims to obtain physical samples of underground rock and soil masses to provide scientific basis for engineering construction, resource development, and environmental protection. This work is directly related to the accuracy of geological condition evaluation and the reliability of engineering design.

[0003] The core purpose of drilling and sampling is to obtain physical evidence that truly reflects underground geological conditions. By analyzing the samples, the geological structure can be identified, the lithology, structural characteristics, and spatial distribution patterns of the strata can be determined, providing a basis for project site selection and foundation design; hydrogeological conditions can be evaluated, aquifers and impermeable layers can be identified, the distribution, permeability, hydraulic conductivity of aquifers and groundwater quality can be analyzed, and the water resource status and the impact of engineering precipitation can be assessed; the physical and mechanical properties of soil and rock can be determined: parameters such as the natural structure, density, moisture content, shear strength, compression coefficient, and permeability coefficient of soil layers can be obtained to evaluate their bearing capacity, stability, and permeability characteristics; and environmental geological problems can be identified: through sample analysis, potential geological hazard risks, soil pollution status, and the impact of engineering construction on the geological environment can be assessed.

[0004] However, existing hydrogeological exploration drilling still has some problems. For example, the current sampling technology mainly uses the drill bit to insert the sampling tube into the ground. After the soil sampling is completed, the sampling tube is taken out to obtain the soil sample. However, since a borehole can only be used for soil sampling once, soil sampling in other locations requires drilling again, which increases the time and cost required for soil sampling. Summary of the Invention

[0005] The purpose of this invention is to provide a drilling and sampling device for hydrogeological exploration to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A drilling and sampling device for hydrogeological exploration includes a bottom support, a guide frame mounted on the bottom support, a hydraulic lifting device mounted on the top of the guide frame, a movable plate mounted on the movable end of the hydraulic lifting device, a driving device mounted on the upper surface of the movable plate, an output end of the driving device passing through the movable plate and mounted on a soil-breaking component, a rotating cylinder provided on the annular surface of the soil-breaking component, a supporting component mounted on the upper end of the rotating cylinder, a connecting component mounted on the annular surface of the soil-breaking component, the connecting component contacting the supporting component, a pressing component mounted on the annular surface of the soil-breaking component, and multiple sampling components mounted on the side of the annular inner surface of the rotating cylinder away from the movable plate, the sampling components contacting the pressing component.

[0007] Furthermore, the soil-breaking component includes a rotating rod, which is installed at the output end of the drive device. The pressing component is installed on the annular surface of the rotating rod, and the connecting component is installed on the annular surface of the rotating rod. A drill bit is installed at the end of the rotating rod away from the drive device, and the upper surface of the drill bit is in contact with the rotating cylinder.

[0008] Furthermore, the connector includes a connecting ring, which is mounted on the annular surface of the rotating rod. A plurality of connecting plates are mounted on the annular surface of the connecting ring, and an inclined block is mounted on the end of the connecting plate away from the mounting ring. The inclined block is in contact with the abutment.

[0009] Furthermore, the supporting member includes an annular plate, which is installed on the upper end of the rotating cylinder. Multiple movable slots are formed within the annular plate, and movable blocks are slidably connected within each slot. A vertical slot penetrating the annular plate is formed at the bottom of the movable slot, and a supporting rod is slidably connected within the vertical slot. The supporting rod is connected to the movable block. A horizontal slot is formed on the side of the movable slot facing the center of the annular plate, and a supporting plate is slidably connected within the horizontal slot. An inclined plate is installed at one end of the supporting plate within the movable slot, and the inclined plate contacts the movable block. A supporting slot is formed at the end of the supporting plate away from the inclined plate. The inclined block and a connecting plate are inserted into the supporting slot. A first elastic element is installed within the horizontal slot, and the end of the first elastic element facing outward from the horizontal slot is connected to the supporting plate.

[0010] Furthermore, the pressing component includes a pressing ring, an annular groove is formed on the annular surface of the rotating rod, the pressing ring is rotatably connected to the annular surface of the annular groove, a pressing plate is installed on the annular surface of the pressing ring, and a conical ring is installed on the lower surface of the pressing plate away from the pressing ring, the conical ring being in sliding contact with the sampling component.

[0011] Furthermore, the sampling component includes a mounting block, which is installed at the bottom of the inner surface of the rotating cylinder. A groove is formed at the end of the mounting block away from the rotating cylinder. Round rods are rotatably connected to both sides of the groove. A mounting cylinder is installed at the end of the two round rods facing the groove. An extension is slidably connected inside the mounting cylinder. The extension is slidably connected to the conical ring. A plurality of second elastic elements are installed on the annular surface of the rotating cylinder. The end of the second elastic element away from the rotating cylinder is connected to the mounting cylinder.

[0012] Furthermore, the extension includes a sampling tube slidably connected inside the mounting tube. A soil-breaking ring is installed at the lower end of the sampling tube, and a pressure rod is installed at the upper end of the sampling tube. A pressure block is installed at the end of the pressure rod away from the sampling tube, and the pressure block is slidably connected to the conical ring.

[0013] Furthermore, a vertical ring is installed on the lower surface of the lower pressure plate, and a support ring is installed at the end of the vertical ring away from the lower pressure plate. The annular surface of the support ring is provided with multiple limiting grooves, and the pressure rod is slidably connected in the limiting grooves.

[0014] Furthermore, a bevel gear is mounted on the annular surface of the rotating rod, and a toothed rod is mounted on the annular surface of the pressure rod, the toothed rod meshing with the bevel gear.

[0015] Furthermore, a blocking block is installed on the lower surface of the mounting block, and the blocking block is in indirect contact with the mounting cylinder.

[0016] Beneficial effects: 1. This invention utilizes a connecting structure consisting of a connecting ring, a connecting plate, and an inclined block installed on the annular surface of a rotating rod. This connecting structure contacts a supporting structure consisting of an annular plate, a moving block, a supporting rod, a supporting plate, an inclined plate, and a first elastic element. This allows the rotating rod to rotate, driving the rotating cylinder to rotate. When the supporting rod contacts the ground, it drives the moving block to push the inclined plate, separating the supporting plate from the connecting structure. Once the connecting structure is no longer in contact with the supporting structure, the rotation and downward movement of the rotating rod will no longer drive the rotating cylinder to rotate and move downward, thus separating the rotating cylinder from the drill bit. At this point, the rotating cylinder reaches the required sampling position. Furthermore, the separation of the drill bit from the rotating cylinder reduces the number of rotating components, thereby lowering energy consumption during the sampling process.

[0017] 2. This invention installs a pressing structure consisting of a pressing ring, a pressing plate, and a conical ring on the annular surface of a rotating rod. The pressing structure contacts and compresses the sampling structure, which consists of a sampling cylinder, a soil-breaking ring, a pressure rod, and a pressure block, causing the sampling structure to tilt. When the rotating cylinder separates from the drill bit, the second elastic element pushes the mounting cylinder to tilt, thereby tilting the sampling structure. At this time, the pressing structure pushes multiple sampling structures inside the cylinder obliquely out of the gap between the rotating cylinder and the drill bit, thus obtaining multiple undamaged soil samples from different areas, thereby improving sampling efficiency.

[0018] 3. This invention installs a bevel gear on the annular surface of the rotating rod and a toothed rod on the annular surface of the pressure rod. The toothed rod meshes with the bevel gear. When the rotating rod rotates, it drives the bevel gear to rotate. The bevel gear drives the toothed rod and the pressure rod to rotate. The rotation of the pressure rod causes the sampling tube to rotate, thereby increasing the soil breaking efficiency of the soil breaking ring installed on the sampling tube, thus improving the efficiency of the sampling tube entering the soil.

[0022] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] Please see Figures 1 to 7 The hydrogeological exploration drilling and sampling device provided in this application includes a bottom support 1, a guide frame 33 installed on the bottom support 1, a hydraulic lifting device 2 installed on the top of the guide frame 33, a movable plate 4 installed on the movable end of the hydraulic lifting device 2, a drive device 3 installed on the upper surface of the movable plate 4, and a rotating rod 8 installed at the output end of the drive device 3 passing through the movable plate 4. A drill bit 7 is installed at the end of the rotating rod 8 away from the drive device 3. The drive device 3 drives the rotating rod 8 and the drill bit 7 to rotate, and the extension of the movable end of the hydraulic lifting device 2 drives the rotating rod 8 and the drill bit 7 to move downward, so that the drill bit 7 can be drilled down.

[0026] A rotating cylinder 6 is provided on the annular surface of the rotating rod 8. An annular plate 5 is installed on the upper end of the rotating cylinder 6. Multiple moving slots are opened in the annular plate 5. Moving blocks 17 are slidably connected in the moving slots. A vertical slot penetrating the annular plate 5 is opened at the bottom of the moving slot. A supporting rod 18 is slidably connected in the vertical slot. The supporting rod 18 is connected to the moving block 17. A horizontal slot 15 is opened on the side of the moving slot facing the center of the annular plate 5. A supporting plate 10 is slidably connected in the horizontal slot 15. An inclined plate 16 is installed at one end of the supporting plate 10 in the moving slot. 16 contacts the moving block 17. A first elastic element 14 is installed in the transverse groove 15. The first elastic element 14 is in a normal state. The end of the first elastic element 14 facing out of the transverse groove 15 is connected to the abutment plate 10. A connecting ring 12 is installed on the annular surface of the rotating rod 8. Multiple connecting plates 13 are installed on the annular surface of the connecting ring 12. An inclined block 11 is installed on the end of the connecting plate 13 away from the mounting ring. An abutment groove 9 is opened on the end of the abutment plate 10 away from the inclined plate 16. The inclined block 11 and the connecting plate 13 are inserted into the abutment groove 9. Thus, when the rotating rod 8 rotates, it can drive the connecting ring 12, the connecting plate 13 and the inclined block 11 to rotate. Since the connecting plate 13 and the inclined block 11 are inserted into the abutment groove 9 and the abutment plate 10 is inserted into the transverse groove 15, the rotation of the rotating rod 8 can drive the annular plate 5 to rotate. Since the rotating cylinder 6 is installed on the lower surface of the annular plate 5, the rotation of the rotating rod 8 can drive the rotating cylinder 6 to rotate.

[0027] In some specific embodiments, the first elastic element 14 described above may be a spring.

[0028] It is understandable that by installing a connecting structure consisting of a connecting ring 12, a connecting plate 13, and an inclined block 11 on the annular surface of the rotating rod 8, and by using the connecting structure to contact the abutment structure consisting of an annular plate 5, a moving block 17, abutting rod 18, abutting plate 10, an inclined plate 16, and a first elastic element 14, the rotating rod 8 rotates and drives the rotating cylinder 6 to rotate. When the abutting rod 18 contacts the ground, the abutting rod 18 drives the moving block 17 to push the inclined plate 16, causing the abutting plate 10 to separate from the connecting structure. When the connecting structure no longer contacts the abutment structure, the rotation of the rotating rod 8 and its downward movement will no longer drive the rotating cylinder 6 to rotate and move downward, thus separating the rotating cylinder 6 from the drill bit 7. At this time, the rotating cylinder 6 reaches the required sampling position. At the same time, after the drill bit 7 separates from the rotating cylinder 6, the number of rotating parts is reduced, thereby reducing the energy consumption during the sampling process.

[0029] An annular groove is formed on the annular surface of the rotating rod 8. A lower pressure ring 19 is rotatably connected to the annular surface of the annular groove. A lower pressure plate 20 is installed on the annular surface of the lower pressure ring 19. A conical ring 21 is installed on the lower surface of the lower pressure plate 20 away from the lower pressure ring 19. An installation block 24 is installed at the bottom of the annular inner surface of the rotating cylinder 6. A groove is formed at the end of the installation block 24 away from the rotating cylinder 6. Round rods 31 are rotatably connected to both sides of the groove. An installation cylinder 25 is installed at the end of the two round rods 31 facing the groove. Multiple second elastic elements 36 are installed on the annular surface of the rotating cylinder 6. The second elastic elements 36 are in a compressed state. The end of the second elastic element 36 away from the rotating cylinder 6 is connected to the installation cylinder 25. A sampling cylinder 26 is slidably connected inside the mounting cylinder 25. A soil-breaking ring 35 is installed at the lower end of the sampling cylinder 26, and a pressure rod 28 is installed at the upper end of the sampling cylinder 26. A pressure block 30 is installed at the end of the pressure rod 28 away from the sampling cylinder 26. The pressure block 30 is slidably connected to the conical ring 21. Since the lower pressure ring 19 is rotatably connected in the annular groove, the rotation of the rotating rod 8 will not drive the lower pressure ring 19 to rotate. However, the downward movement of the rotating rod 8 can drive the lower pressure ring 19 to move downward. The downward movement of the lower pressure ring 19 will then drive the lower pressure plate 20 and the conical ring 21 to move downward, and then contact the pressure block 30 and squeeze the pressure block 30, causing the pressure rod 28 to tilt.

[0030] In some specific embodiments, the second elastic element 36 described above may be a spring.

[0031] Understandably, by installing a pressing structure consisting of a pressing ring 19, a pressing plate 20, and a conical ring 21 on the annular surface of the rotating rod 8, and by using the pressing structure to contact and compress the sampling structure consisting of a sampling cylinder 26, a soil breaking ring 35, a pressure rod 28, and a pressure block 30, the sampling structure is tilted. When the rotating cylinder 6 separates from the drill bit 7, the second elastic element 36 pushes the mounting cylinder 25 to tilt, thereby tilting the sampling structure. At this time, the pressing structure pushes multiple sampling structures inside the cylinder obliquely out of the gap between the rotating cylinder 6 and the drill bit 7, thereby obtaining multiple undamaged soil samples from different areas, thus improving sampling efficiency.

[0032] A bevel gear 23 is mounted on the annular surface of the rotating rod 8, and a rack 27 is mounted on the annular surface of the pressure rod 28. The rack 27 meshes with the bevel gear 23. In order to control the tilt angle of the sampling structure, a blocking block 34 is mounted on the lower surface of the mounting block 24. The blocking block 34 is in indirect contact with the mounting cylinder 25. When the sampling structure contacts the blocking block 34, the sampling structure reaches its maximum tilt angle. At the same time, when the sampling structure reaches its maximum tilt angle, the bevel gear 23 meshes with the rack 27.

[0033] By installing a bevel gear 23 on the annular surface of the rotating rod 8 and a toothed rod 27 on the annular surface of the pressure rod 28, the toothed rod 27 meshes with the bevel gear 23. When the rotating rod 8 rotates, it drives the bevel gear 23 to rotate. The bevel gear 23 then drives the toothed rod 27 and the pressure rod 28 to rotate. The rotation of the pressure rod 28 causes the sampling cylinder 26 to rotate, thereby increasing the soil breaking efficiency of the soil breaking ring 35 installed on the sampling cylinder 26 and improving the efficiency of the sampling cylinder 26 entering the soil.

[0034] A vertical ring 29 is installed on the lower surface of the lower pressure plate 20. A support ring 22 is installed at the end of the vertical ring 29 away from the lower pressure plate 20. Multiple limiting grooves 32 are opened on the annular surface of the support ring 22. When the sampling structure is tilted, the pressure rod 28 is slidably connected in the limiting groove 32. When the sampling is completed, the movable end of the hydraulic lifting device 2 retracts and drives the rotating rod 8 to move upward. The support ring 22 also moves upward. As the support ring 22 moves, it can contact the pressure block 30. At this time, the sampling cylinder 26 can be pulled back into the rotating cylinder 6.

[0035] In summary, when using the above-mentioned hydrogeological exploration drilling and sampling device of this application, the hydraulic lifting device 2 and the drive device 3 are started first. The movable end of the hydraulic lifting device 2 extends to drive the moving plate 4 to move downward. The downward movement of the moving plate 4 drives the drive device 3 to move downward. The downward movement of the drive device 3 drives the rotating rod 8 and the drill bit 7 to move downward. At the same time, the drive device 3 drives the rotating rod 8 to rotate. The rotation of the rotating rod 8 drives the drill bit 7 to rotate, thereby causing the drill bit 7 to break through the ground and move towards the bottom of the earth.

[0036] At the same time, the rotating rod 8 rotates the connecting structure composed of the connecting ring 12, the connecting plate 13 and the inclined block 11. The rotation of the connecting structure drives the support plate 10 to rotate. Since the support plate 10 is inserted into the annular plate 5, the rotation of the connecting structure drives the rotating cylinder 6 to rotate through the support plate 10. At the same time, the support structure transmits a downward force to the rotating cylinder 6 through the support plate 10, causing the rotating cylinder 6 to move with the drill bit 7 to the ground until the end of the support rod 18 away from the moving block 17 contacts the ground.

[0037] When the abutment rod 18 can no longer move after contacting the ground, and the moving plate 4 continues to drive the annular plate 5 to move downward through the connecting structure, the position of the abutment rod 18 in the moving groove gradually rises, thereby driving the moving block 17 to rise in the moving groove. At this time, the moving block 17 squeezes the inclined plate 16 and uses the inclined plate 16 to drive the abutment plate 10 to move into the transverse groove 15 until the abutment plate 10 separates from the connecting structure. After that, the connecting structure no longer drives the rotating cylinder 6 to rotate when it rotates with the rotating rod 8, and the rotating cylinder 6 also stops moving downward. At this time, the predetermined sampling depth is also reached.

[0038] As the rotating rod 8 and drill bit 7 extend downwards along with the movable end of the hydraulic lifting device 2, the drill bit 7 separates from the lower end of the rotating cylinder 6. The second elastic element 36 pushes the mounting cylinder 25 to tilt, thereby tilting the sampling structure. At the same time, the pressing structure, consisting of a pressing ring 19, a pressing plate 20, and a conical ring 21, installed on the annular surface of the rotating rod 8, contacts and squeezes the sampling structure, consisting of a sampling cylinder 26, a soil-breaking ring 35, a pressure rod 28, and a pressure block 30, installed inside the rotating cylinder 6. This causes the sampling cylinder 26 to deflect within the groove in the mounting block 24 until the mounting cylinder 25 contacts the blocking block 34. At this point, the sampling cylinder 26 stops deflecting. As the pressing structure continues to squeeze the sampling structure, the sampling structure can only tilt downwards and extend obliquely outwards from the gap between the rotating cylinder 6 and the drill bit 7, sampling the soil at that location.

[0039] When the mounting cylinder 25 contacts the blocking block 34, the toothed rod 27 installed on the annular surface of the sampling cylinder 26 meshes with the bevel gear 23 installed on the annular surface of the rotating rod 8. The rotation of the bevel gear 23 drives the toothed rod 27 to rotate, which in turn drives the pressure rod 28 to rotate. The rotation of the pressure rod 28 drives the sampling cylinder 26 and the soil breaking ring 35 to rotate, thereby increasing the soil breaking efficiency of the soil breaking ring 35 installed on the sampling cylinder 26 and thus improving the efficiency of the sampling cylinder 26 entering the soil.

[0040] When the mounting cylinder 25 tilts, the pressure rod 28 is inserted into the limiting groove 32 opened on the support ring 22. After sampling is completed, the movable end of the hydraulic lifting device 2 retracts, causing the moving plate 4 to move upward. The upward movement of the moving plate 4 drives the rotating rod 8 to move upward through the driving device 3. The upward movement of the rotating rod 8 causes the pressing structure to move upward and separate from the sampling structure. However, since the pressure rod 28 is inserted into the limiting groove 32, the support ring 22 contacts the pressure block 30 when it moves upward with the rotating rod 8, and pulls the pressure block 30 to move upward as well. Then, by pulling the pressure block 30, the pressure rod 28 and the sampling ring move back into the rotating cylinder 6 until they are completely inside the rotating cylinder 6. Then, the rotating cylinder 6 is taken out from the ground, and multiple undamaged soil samples from different areas can be obtained.

Many modifications and variations will be apparent to those skilled in the art.
