Description
Technical Field
[0001] This invention relates to the field of geological exploration, and more particularly to a geological prospecting detector. Background Technology
[0002] With the continuous advancement of industrialization and the increasing intensity of mineral resource development, the demand for refined exploration of underground metallic and non-metallic minerals and related geological structures is growing. In geological prospecting, traditional methods such as drilling and trenching have disadvantages such as high destructiveness, high cost, and long construction period. Especially in complex terrain areas such as mountains and hills, borehole layout is difficult and construction safety risks are high, making it difficult to fully meet the needs of rapid exploration and large-scale deployment.
[0003] Ground-penetrating radar (GPR), as a novel non-destructive electromagnetic wave detection technology, boasts advantages such as high resolution, intuitive imaging, and high construction efficiency. It is increasingly being applied in geological prospecting, engineering geological exploration, karst and fault detection, and other fields. In mineral prospecting applications, by deploying survey lines and moving GPR across the surface, it is possible to identify the interfaces between different underground media and the reflection characteristics of ore bodies without damaging the surface, providing crucial information for mineral resource evaluation and construction design.
[0004] However, in existing technologies, ground-penetrating radars (GPRs) used for geological prospecting are mostly installed using simple trolleys or backpack-mounted supports. Existing devices typically rigidly fix the GPR to a support frame, with the distance and angle between the radar antenna and the ground surface being essentially non-adjustable. When operating on slopes, stepped terrain, or uneven surfaces, the radar antenna cannot always maintain near-parallel alignment with the ground, leading to insufficient energy coupling, distorted echo signals, and affecting detection depth and imaging quality.
[0005] Therefore, it is necessary to provide a new geological prospecting detector to solve the above-mentioned technical problems. Summary of the Invention
[0006] To solve the above-mentioned technical problems, the present invention provides a geological prospecting detector, which solves the problem that existing devices usually rigidly fix the ground penetrating radar to the support frame, and the distance and angle between the radar antenna and the ground surface are basically not adjustable.
[0007] The geological prospecting detector provided by the present invention includes a support beam and a ground penetrating radar. Wheels can be detachably installed at both ends of the support beam. A mounting platform is fixed on the support beam. A first groove is provided on the mounting platform. Two support seats are slidably arranged inside the first groove. A first support rod is installed on each of the two support seats. The bottom of the first support rod is integrally formed with a C-shaped rod, and a first connecting block is fixed to the bottom of the C-shaped rod. A spline groove is provided on the first connecting block. The ground-penetrating radar has two fixed first connecting seats at intervals. A rotating shaft is movably arranged on the two first connecting seats. A second connecting block is rotatably connected to both ends of the rotating shaft. A spline is fixed on the second connecting block. The spline is used in conjunction with the spline groove.
[0008] In a preferred embodiment, a bidirectional lead screw is movably disposed inside the first groove via a bearing. The two ends of the bidirectional lead screw pass through the two support seats respectively, and the support seats are threadedly connected to the bidirectional lead screw.
[0009] In a preferred embodiment, one end of the bidirectional lead screw extends out of the mounting platform and is fixed with a hexagonal block.
[0010] In a preferred embodiment, an adjusting gear is mounted on the rotating shaft; A central seat is fixed at the center of the mounting platform, an adjusting column is provided through the central seat, and a pair of sliders are fixed on the adjusting column. The sliders are slidably connected to the central seat. A friction plate is fixed on the adjusting column, and a hand-tightening screw is provided on both sides of the center seat. The threaded end of the hand-tightening screw is inserted into the center seat and extends to the surface of the friction plate. A mounting rod is fixed to the bottom of the adjusting column, and a rack is mounted on the mounting rod. The rack meshes with the adjusting gear.
[0011] In a preferred embodiment, a first handle is mounted on the top of the adjusting column.
[0012] In a preferred embodiment, a top seat is fixed to the top of each of the two first support rods, two second support rods are fixed to one side of each of the two first support rods, and a second connecting seat is fixed to the bottom of each of the two second support rods. A second sliding groove is provided on the second connecting seat, and the top seat is slidably connected to the second sliding groove.
[0013] In a preferred embodiment, an adjusting sleeve is fixed to the top of the second support rod, and a second handle is slidably disposed inside the adjusting sleeve. The second handle is provided with a plurality of through holes spaced apart, and the second handle is fixedly connected to the adjusting sleeve by a high-strength bolt.
[0014] In a preferred embodiment, a shelf for placing a tablet computer is fixed to the second handle. A first limiting seat and a second limiting seat are spaced apart on the shelf. The first limiting seat is fixedly connected to the shelf. A third sliding groove is provided on the shelf. The second limiting seat is slidably connected to the third sliding groove. A limiting spring is provided inside the third slide groove. One end of the limiting spring is fixed to the wall of the third slide groove, and the other end of the limiting spring is fixed to the second limiting seat.
[0015] In a preferred embodiment, the bidirectional lead screw, adjusting gear, rack, and high-strength bolts are all galvanized.
[0016] The beneficial effects of this invention are: 1. This invention utilizes a rack and pinion-adjustable gear transmission mechanism combined with a spline connection structure to achieve an angle adjustment range of -15° to +15° for the ground-penetrating radar, precisely adapting to complex terrain slopes from 0° to 30°. The ZOND-12e ground-penetrating radar employed achieves a detection resolution of 0.1m. Combined with the angle adjustment function, it ensures optimal coupling between the detection surface and the ground, effectively reducing electromagnetic wave reflection signal distortion and significantly lowering detection errors. Whether on plains, hills, or gentle slopes, the angle of the ground-penetrating radar can be quickly adapted by adjusting the adjusting column at the central base, driving the rack and pinion transmission, greatly expanding the application scenarios of the equipment.

[0018] 3. The second handle adopts a height-adjustable structure. By adjusting the fit between the sleeve and the through hole, the adjustment range is 0-200mm, which can accommodate workers of different heights from 1.6m to 1.9m, avoiding back fatigue caused by unsuitable handle height.

[0029] This invention employs the ZOND-12e ground-penetrating radar, a model specifically designed for geological prospecting. It has a detection depth range of 0.5m-30m and a detection resolution of 0.1m, effectively identifying underground metallic and non-metallic minerals and geological structural interfaces.

It can communicate in real-time with a tablet via Bluetooth or WiFi and is compatible with the data viewing function of this device's platform.
[0030] The bidirectional ball screw 14 is an SFU1605 type bidirectional ball screw with a length of 800mm, a lead of 5mm, a thread accuracy grade of C7, and a hot-dip galvanized surface with a coating thickness of 8-12μm to ensure corrosion resistance and transmission accuracy. The adjusting gear 16 and rack 23 have a module of 2, 20 teeth, and a tooth width of 25mm. The rack module matches the gear, with a length of 300mm. Both are made of 45# steel and hot-dip galvanized, with a meshing clearance controlled at 0.05-0.1mm. The high-strength bolt 32 is an M10×40 grade 8.8 high-strength carbon steel bolt with a hot-dip galvanized surface and a breaking load ≥80kN to ensure the connection stability between the adjusting sleeve and the second handle. The hand-tightening screw 21 is an M8×30 internal hexagonal hand-tightening screw with a thread accuracy of 6H. The head is equipped with anti-slip texture for easy hand operation, and a wear-resistant rubber pad is attached to the thread end to enhance the friction with the friction plate.
[0031] The assembly process for this equipment is as follows: 1. Assembly of basic support structure: Place the support beam 1 horizontally, and install the wheels 3 detachably at both ends of the beam using M16 bolts to ensure that the wheels 3 rotate flexibly and that the braking device functions properly. Mounting platform 2 is fixed to the middle of support beam 1 with 4 M12 expansion bolts to ensure that mounting platform 2 is level and does not tilt or wobble; A double-ended lead screw 14 is installed in the first groove 4 of the mounting platform 2 using a deep groove ball bearing (model 6204). The gap between the two ends of the double-ended lead screw 14 and the inner wall of the first groove 4 is uniform, and there is no jamming during rotation. Two support seats 5 are respectively fitted onto the two ends of the double-ended lead screw 14 to ensure good thread engagement between the support seats 5 and the double-ended lead screw 14 and smooth sliding. A hexagonal block 15 is fixed at one end of the double-ended lead screw 14 that extends out of the mounting platform 2, with a distance of 24mm between opposite sides for easy wrench operation.
[0032] 2. Installation and angle adjustment mechanism assembly of ground penetrating radar 38: An inverted C-shaped rod 7 is integrally formed at the bottom of the first support rod 6, a first connecting block 8 is welded to the bottom of the inverted C-shaped rod 7, and a spline groove 9 is machined on the first connecting block 8; Two first connecting seats 10 are fixed on both sides of the ZOND-12e ground penetrating radar 38 at a distance of 150mm. A rotating shaft 11 passes through the two first connecting seats 10. The two ends of the rotating shaft 11 are connected to the second connecting block 12 through rolling bearings of type 6203. A spline 13 is fixed on the second connecting block 12. Two first support rods 6 are respectively installed on support base 5, and the initial connection between ground penetrating radar 38 and shaped rod 7 is achieved through the cooperation of spline 13 and spline groove 9. A center seat 17 is welded at the center of the mounting platform 2. A groove matching the slider 19 is opened inside the center seat 17. An adjusting column 18 passes through the center seat 17. A pair of sliders 19 are fixed on the adjusting column 18. A friction plate 20 is welded in the middle of the adjusting column 18. Hand screws 21 are installed on both sides of the center seat 17 to ensure that the threaded end of the hand screw 21 can extend to the surface of the friction plate 20. A mounting rod 22 is welded to the bottom of the adjusting column 18, and a rack 23 is fixed to the mounting rod 22 by bolts to ensure that the rack 23 meshes precisely with the adjusting gear 16 on the rotating shaft 11; a first handle 24 made of aluminum alloy with anti-slip surface is installed on the top of the adjusting column 18 to facilitate pulling the adjusting column 18.
[0033] 3. Assembly of auxiliary support and operating mechanism: Top seats 25 are welded to the top of the two first support rods 6, and two second support rods 26 are welded to one side of the first support rods 6. Second connecting seats 27 are welded to the bottom of the second support rods 26. Second sliding grooves 28 are opened on the second connecting seats 27. Top seats 25 are embedded into the second sliding grooves 28 and smooth sliding is ensured. An adjusting sleeve 29 is welded to the top of the second support rod 26, and the second handle 30 is inserted into the adjusting sleeve 29 to ensure that the second handle 30 slides without jamming; a high-strength bolt 32 is passed through the through hole 31 of the adjusting sleeve 29 and the second handle 30 to fix the two. A shelf 33 is welded to the top of the second handle 30. A first limiting seat 34 is fixed on the shelf 33. A third sliding groove 36 is opened. The second limiting seat 35 is slidably connected to the third sliding groove 36. A limiting spring 37 is installed inside the third sliding groove 36. One end of the limiting spring 37 is fixed to the groove wall of the third sliding groove 36, and the other end is fixed to the second limiting seat 35, ensuring that the second limiting seat 35 can be elastically clamped under the action of the spring.
[0034] Equipment movement and positioning: The staff can adjust the height of the second handle 30 according to their own height: loosen the high-strength bolt 32, pull the second handle 30 to the appropriate position to fit the height of 1.6m-1.9m, the adjustment range is 0-200mm, align the adjusting sleeve 29 with the through hole 31 of the second handle 30, insert the high-strength bolt 32 and tighten it, the torque is controlled at 30N・m; The staff member holds the second handle 30 and pushes the equipment to the area to be detected. According to the detection route plan, the equipment is fixed by the braking device of the wheel 3 to ensure that the equipment does not move during the detection process.
[0035] Tablet PC Installation and Data Connection: Pull the second limiting seat 35 outward to compress the limiting spring 37. Place the tablet computer (7-12 inches in size) between the first limiting seat 34 and the second limiting seat 35 on the shelf 33. Release the second limiting seat 35. Under the elastic force of the limiting spring 37, the tablet computer is clamped and fixed. The anti-slip rubber pad can prevent the device from sliding. Turn on the ground-penetrating radar 38 and the tablet computer, establish a connection via Bluetooth or WiFi, open the accompanying data acquisition software such as ZONDSuite, and set the detection parameters such as frequency, detection depth, and sampling rate.
[0036] Ground penetrating radar with 38-degree angle adjustment adapts to complex terrain: The slope of the ground in the area to be detected is measured using a slope meter, and the measured slope is 15°. Loosen the hand screws 21 on both sides of the center seat 17, and pull the adjusting column 18 up and down through the first handle 24. The adjusting column 18 drives the mounting rod 22 and rack 23 to move synchronously. The rack 23 meshes with the adjusting gear 16 to drive the rotating shaft 11 to rotate, thereby driving the ground penetrating radar 38 to rotate. Observe the attitude display of the ground penetrating radar 38 on the tablet or observe the contact state between the detection surface of the ground penetrating radar 38 and the ground with the naked eye. Adjust the angle of the ground penetrating radar 38 to match the ground slope. For example, if the slope is 15°, adjust the ground penetrating radar 38 downward by 15° to ensure that the detection surface is parallel to the ground. After adjustment, tighten the hand screws 21 on both sides clockwise. The rubber pads at the threaded ends of the hand screws 21 fit tightly against the friction plate 20, fixing the position of the adjusting column 18 under the action of friction, thereby locking the angle of the ground penetrating radar 38 with an angle fixing error of ≤0.5°.
[0037] Exploration operation implementation: Once the data acquisition function of the ground-penetrating radar 38 is activated, the staff pushes the equipment along the preset detection route at a constant speed of 0.5-1m / s. The ground-penetrating radar 38 transmits and receives electromagnetic waves in real time, and the detection data is wirelessly transmitted to a tablet computer. The staff can view the detection images in real time on the tablet computer and identify abnormal signals of underground mineral resources. If the slope of the terrain in the detection area changes, repeat the angle adjustment operation in step 3 to ensure detection accuracy throughout the entire process.
[0038] After the detection operation is completed, turn off the ground penetrating radar 38 and the tablet computer, and remove the tablet computer. If the ground-penetrating radar 38 needs to be disassembled for maintenance or transportation, use a 24mm open-end wrench to rotate the hexagonal block 15, which will drive the double-ended lead screw 14 to rotate. Since the support seat 5 is threadedly connected to the double-ended lead screw 14 and the threads at both ends of the double-ended lead screw 14 turn in opposite directions, the two support seats 5 will move away from each other along the first sliding groove 4, thereby causing the spline groove 9 of the first connecting block 8 to disengage from the spline 13 of the second connecting block 12. At this time, the ground-penetrating radar 38 can be removed directly. The same principle applies during installation.
[0039] Regularly check the galvanized layer of core metal components such as the bidirectional lead screw 14, adjusting gear 16, and rack 23 to ensure it is intact. If rust is found, promptly perform re-galvanizing. Check bolted connections such as high-strength bolts 32 and hand-tightening screws 21 for looseness and tighten them regularly to ensure stable equipment performance.
[0040] Working principle of the invention: When using this detector, the operator can move the entire device to the position to be detected by pulling the second handle 30. The position of the second handle 30 in the adjusting sleeve 29 can be adjusted according to the operator's height. After adjustment, the adjusting sleeve 29 and the second handle 30 can be connected together by high-strength bolts 32. When in use, staff can place the tablet computer used in conjunction with the ground penetrating radar 38 on the platform 33. The tablet computer can be fixed between the two limit seats by the limit spring 33 and the second limit seat 35, so that staff can easily view the information detected by the ground penetrating radar 38. According to the slope of the ground being detected, the staff can loosen the two hand screws 21, and then pull the first handle 24 to move the adjusting column 18 and the rack 23. Under the transmission action of the rack 23 and the gear 12, the rotating shaft 11 drives the ground penetrating radar 38 to adjust the angle relative to the slanted rod 7. After the adjustment is completed, the two hand screws 21 are turned in sequence. Under the action of the friction between the hand screws 21 and the friction plate 20, the position of the ground penetrating radar 38 is fixed. When it is necessary to disassemble the ground penetrating radar 38, the staff only needs to use a wrench to rotate the hexagonal block 15 to drive the double-ended lead screw 14 to rotate. Under the action of the double-ended lead screw 14, the two support seats 5 move away from each other. At this time, the spline 13 on the second connecting block 12 is disengaged from the spline groove 9 on the first connecting block 8. At this time, the ground penetrating radar 38 can be removed. The installation is the same.
