Description

Technical Field

[0001] This invention belongs to the field of geological exploration technology, specifically a physical exploration device for detecting complex geological structures. Background Art

[0002] Geological drilling is an exploration method that uses mechanical drilling tools to drill into the ground to form holes and extract rock cores or cuttings to directly observe and analyze geological information such as lithology and structure of strata. During the drilling process, the drill rod and drill bit break up the rock and soil, and use mud circulation or dry coring technology to bring rock samples from different underground depths to the surface for geologists to record, test and analyze on-site, thereby revealing the underground geological structure and providing basic data for mineral exploration, engineering construction, hydrogeological surveys and other purposes.

[0003] However, traditional geological drilling often uses single-pressure or low-frequency impact methods. The drill bit slowly penetrates the formation by relying solely on its own weight or low-frequency hammering. Once it encounters hard rock formations such as dense sandstone, quartz veins, and granite, the cutting resistance increases sharply, the drilling speed drops drastically, and even the phenomenon of "slipping and not advancing" occurs. The auger and drill bit are driven coaxially, and the rotation speed is restricted by the drilling speed. It is easy to idle in loose layers and get blocked in viscous formations, resulting in low and mixed sampling rates.

[0004] To address this issue, those skilled in the art have proposed a physical detection device for probing complex geological structures.

[0005] The information disclosed above in this background section is only for enhancing the understanding of the background section of this invention, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a physical detection device for detecting complex geological structures, thereby solving the problem that existing geological drilling methods often employ single-pressure or low-frequency impact techniques.

[0007] To achieve the above objectives, the present invention provides a physical detection device for detecting complex geological structures, comprising a base, several wheels symmetrically and rotatably connected to the sides of the base, a handrail fixedly connected to the top of the base, a detection component mounted on the base, the detection component comprising a drill pipe, an auger fixedly connected inside the drill pipe, a first motor fixedly connected to the top of the auger, a receiving plate rotatably mounted at the top of the drill pipe, a second motor fixedly connected to the receiving plate, a gear fixedly connected to the output end of the second motor, a toothed ring sleeved on the outside of the drill pipe, a pressing member mounted on the base, and the receiving plate mounted on the pressing member.

[0008] Preferably, the pressing component includes two lead screws symmetrically rotatably connected to the base, a conveyor belt is sleeved between the bottom ends of the two lead screws, and two upright plates are symmetrically fixed to the base.

[0009] Preferably, the pressing component further includes a first bevel gear fixedly connected to a lead screw, a third motor fixedly connected to the top of the base, and a second bevel gear fixedly connected to the output end of the third motor.

[0010] Preferably, the first motor is fixedly connected to the conveying shaft of the auger, the drill pipe is rotatably connected to the receiving plate, the gear meshes with the gear ring, the two lead screws are respectively threaded to both ends of the receiving plate, the middle part of the conveyor belt is sleeved on two vertical plates, and the first bevel gear and the second bevel gear mesh.

[0011] Preferably, two adjustment components are symmetrically arranged on the top of the base. Each adjustment component includes a guide rail fixedly connected to the top of the base, the guide rail is provided with scale markings, and the guide rail is provided with threaded holes.

[0012] Preferably, the adjusting assembly further includes a slide rod fixedly connected to the receiving plate, a fixing plate slidably connected inside the guide rail, and bolts symmetrically threaded onto the fixing plate.

[0013] Preferably, the threaded holes are provided in multiple ways and are evenly distributed in a vertical direction, the slide rod is slidably connected to the guide rail, and the bolt is threadedly connected to the threaded holes.

[0014] Preferably, the base has a stabilizing component at its bottom, the stabilizing component including a fixing block fixedly connected to the bottom of the base, a first lever and a second lever rotatably connected to the fixing block, a first half gear fixedly connected to the end of the first lever, and a second half gear fixedly connected to the end of the second lever.

[0015] Preferably, an electric actuator is fixedly connected to the base, and two connecting rods are rotatably connected to both the first and second levers. A connecting seat is rotatably connected between the two connecting rods, and a pestle is fixedly connected to the bottom of the connecting seat.

[0016] Preferably, the end of the first lever away from the first half gear is rotatably connected to the output end of the electric actuator, the first half gear and the second half gear mesh with each other, and two stabilizing components are provided and arranged symmetrically.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This invention achieves a three-in-one structure of rotation, pressing, and conveying by setting up a detection component. The second motor independently drives the drill pipe to rotate and cut at high speed via gears and a gear ring, which, together with the lead screw, presses down at a uniform speed. This significantly reduces the cutting resistance of hard rock and doubles the drilling efficiency. The auger is independently speed-adjusted by the first motor and is not restricted by the rotation speed of the drill pipe. It can slow down to prevent dry running in loose layers and speed up to self-clean in viscous strata. Rock cuttings are continuously and completely conveyed upwards, resulting in a high sampling rate and strong representativeness. The drill pipe is rotatably connected to the receiving plate, which transmits torque and isolates vibration. The whole machine has high stability and high modular integration, and can be quickly disassembled and maintained. It is suitable for continuous operation in complex strata such as uneven soft and hard areas and fractured zones.

[0019] 2. This invention, by setting up an adjustment component, transforms depth control from empirical estimation to visualized, lockable millimeter-level adjustment. The guide rail is engraved with vertical scales, allowing operators to intuitively read the current drilling depth. Tightening the bolts and corresponding threaded holes locks the position of the fixing plate. The slide rod slides along the guide rail, driving the receiving plate to move up and down for positioning. Once the detection component reaches the target scale, it can prevent rebound or sinking caused by drilling reaction force and achieve precise adjustment of the detection depth of the detection component. In complex strata such as alternating layers of soft and hard rock and fractured zones where frequent depth adjustments are required, this structure significantly reduces repeated drilling and measurement time, improving operational efficiency and data accuracy. At the same time, the modular design facilitates quick disassembly and maintenance.

[0020] 3. This invention uses two electric actuators to extend and retract, which simultaneously drive two sets of first and second levers to rotate in opposite directions, causing two drills to vertically penetrate or be pulled out of the ground. The entire process takes only a few seconds. The meshing of the first and second half gears ensures that the left and right drills move synchronously, avoiding single-point force that could cause the machine to tilt. The cone shape of the drill tip, combined with high thrust, allows it to penetrate deep into unstable strata such as gravel, soft mud, and slopes, significantly suppressing drilling reverse torque and surface slippage, ensuring that the borehole inclination is controlled within specifications. The symmetrically arranged double stabilizing units can be quickly deployed and retrieved even in confined spaces, improving operational safety and relocation efficiency.

In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the invention will become readily apparent from the accompanying drawings and the following detailed description.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. It should be noted that the accompanying drawings are schematic and not illustrated to scale. For clarity and convenience, the relative sizes and proportions of the parts shown in the drawings have been exaggerated or reduced in size, and any size is only illustrative and not limiting.

[0031] Example 1:

[0032] Please see Figure 1 - Figure 7As shown, a physical detection device for detecting complex geological structures includes a base 1, with several wheels 2 symmetrically rotatably connected to the sides of the base 1, a handrail 3 fixedly connected to the top of the base 1, and a detection component 4 mounted on the base 1. The detection component 4 includes a drill pipe 41, an auger 42 fixedly connected inside the drill pipe 41, a first motor 43 fixedly connected to the top of the auger 42, a receiving plate 44 rotatably mounted at the top of the drill pipe 41, a second motor 45 fixedly connected to the receiving plate 44, and a gear 46 fixedly connected to the output end of the second motor 45. The drill pipe 41 is externally... A toothed ring 47 is fitted onto the base 1, and a pressing component 48 is installed on the base 1. A receiving plate 44 is installed on the pressing component 48. An analysis module is installed inside the base 1 to analyze the physical properties of the collected soil and rock samples, including parameters such as hardness, density, and moisture. The base 1 serves as the core support structure of the entire device. The base 1 not only supports all functional components but also allows for overall movement via wheels 2 symmetrically arranged on its sides. A handrail 3 is provided on the top of the base 1 for easy manual pushing or directional control, while a stabilizing component 6 is integrated at the bottom to ensure no displacement during the exploration process. The wheels 2 are rotatably connected to the base 1, and the symmetrical layout allows the device to move smoothly in complex terrain while providing steering flexibility and reducing the difficulty of manual pushing. The handrail 3 is fixed to the top of the base 1 and serves as a key component for human-machine interaction. Operators can push, turn, or stabilize the device through the handrail 3. The drilling pipe 41 serves as the channel for drilling and sampling. It has an auger 42 inside and a toothed ring 47 on the outside for synchronous rotation and pressing. The conveying shaft of the auger 42 is connected to the first motor 43 to lift the soil and rock samples collected during drilling upwards. The analysis module is transported to the base 1. The first motor 43 drives the auger 42 to rotate, realizing continuous sample transport. The receiving plate 44 serves as the connecting hub between the drilling tube 41 and the pressing component 48. It not only supports the drilling tube 41, but also cooperates with the adjusting component 5 through the slide rod 54 on it to realize depth adjustment. The second motor 45 meshes with the gear ring 47 through the gear 46 to drive the drilling tube 41 to rotate as a whole, forming a compound action of rotation and pressing, which improves drilling efficiency. The gear ring 47 is fixed to the outer wall of the drilling tube 41 and meshes with the gear 46 to transmit torque and realize the rotation function.

[0033] Specifically, the pressing component 48 includes two lead screws 481 symmetrically rotatably connected to the base 1. A conveyor belt 482 is sleeved between the bottom ends of the two lead screws 481. Two upright plates 483 are symmetrically fixed to the base 1. The external threads of the lead screws 481 engage with the nuts at both ends of the receiving plate 44, directly converting the rotational motion of the third motor 485 into the linear lifting and lowering of the receiving plate 44. The conveyor belt 482 is looped around the bottom ends of the two lead screws 481, forcing the left and right lead screws 481 to synchronize, eliminating jamming or skew caused by unilateral lag. The flexible conveyor belt 482 can buffer instantaneous impact. The upright plate 483 serves as both a belt tensioning and guiding support, and also provides a lower rotation fulcrum for the lead screws 481, improving the overall rigidity of the machine.

[0034] Furthermore, the pressing component 48 also includes a first bevel gear 484 fixedly connected to a lead screw 481, a third motor 485 fixedly connected to the top of the base 1, and a second bevel gear 486 fixedly connected to the output end of the third motor 485. The first bevel gear 484 and the second bevel gear 486 reverse direction by 90 degrees and reduce speed and increase torque, so as to efficiently transmit the output of the horizontally arranged third motor 485 to the vertical lead screw 481. The third motor 485 is used to provide driving force for the second bevel gear 486.

[0035] Furthermore, the first motor 43 is fixedly connected to the conveying shaft of the auger 42, the drill pipe 41 is rotatably connected to the receiving plate 44, the gear 46 meshes with the gear ring 47, the two lead screws 481 are respectively threaded to the two ends of the receiving plate 44, the middle of the conveyor belt 482 is sleeved on the two vertical plates 483, and the first bevel gear 484 and the second bevel gear 486 mesh with each other.

[0036] As described above, the operator pushes the equipment to the target position using the handle 3, starts the third motor 485, and drives the two lead screws 481 to rotate synchronously through the meshing of the second bevel gear 486 and the first bevel gear 484. The conveyor belt 482 ensures synchronicity. The rotation of the lead screws 481 causes the receiving plate 44 to move vertically downward, driving the drill pipe 41 and the auger 42 to press down. At the same time, the second motor 45 drives the gear 46 to rotate, causing the drill pipe 41 to rotate in the opposite direction through the gear ring 47, forming a combined action of rotation and downward pressure. The first motor 43 drives the auger 42 to rotate, transporting the soil and rock sample upward along the drill pipe 41 to the analysis module in the base 1 for real-time analysis. By setting the detection... Component 4 integrates rotation, pressing, and conveying into a single structure. The second motor 45 independently drives the drill pipe 41 to rotate and cut at high speed via gear 46 and gear ring 47. This, combined with the screw 481 pressing down at a uniform speed, significantly reduces the cutting resistance of hard rock and doubles the drilling efficiency. The auger 42 is independently speed-adjusted by the first motor 43 and is not affected by the rotation speed of the drill pipe 41. It can reduce speed to prevent dry running in loose layers and increase speed to self-clean in viscous formations. Rock cuttings are continuously and completely conveyed upwards, resulting in a high sampling rate and strong representativeness. The drill pipe 41 is rotatably connected to the receiving plate 44, which transmits torque and isolates vibration. The machine has high stability and high modular integration, allowing for quick disassembly and maintenance. It is suitable for continuous operation in complex formations such as uneven soft and hard formations and fractured zones.

[0037] Example 2:

[0038] Please see Figure 5 - Figure 6As shown, this embodiment is basically the same as the previous embodiment, except that two adjustment components 5 are symmetrically arranged on the top of the base 1. The adjustment component 5 includes a guide rail 51 fixedly connected to the top of the base 1. The guide rail 51 is provided with scale markings 52 and threaded holes 53. The adjustment component 5 is used to achieve precise control and visualization of the drilling depth. The guide rail 51 is fixed to the base 1 and is used to provide a guide path for the receiving plate 44. The guide rail 51 is provided with scale markings 52 to intuitively display the current drilling depth.

[0039] Specifically, the adjustment assembly 5 also includes a slide rod 54 fixedly connected to the receiving plate 44, a fixing plate 55 slidably connected inside the guide rail 51, and bolts 56 symmetrically threaded on the fixing plate 55. The slide rod 54 is fixed to the receiving plate 44 and slides along the guide rail 51 to ensure vertical stability during the pressing process. The fixing plate 55 locks the position of the slide rod 54 by engaging with the threaded holes 53 of different heights on the guide rail 51 through the bolts 56, thereby realizing depth adjustment and fixation.

[0040] Furthermore, multiple threaded holes 53 are provided and are evenly distributed in a vertical direction. The slide rod 54 is slidably connected to the guide rail 51, and the bolt 56 is threadedly connected to the threaded hole 53.

[0041] As can be seen from the above, the guide rail 51 is engraved with vertical scales, allowing the operator to intuitively read the current drilling depth. Tightening the bolt 56 and the corresponding threaded hole 53 locks the position of the fixing plate 55. The slide rod 54 slides along the guide rail 51, driving the receiving plate 44 to be positioned up and down. After the detection component 4 reaches the target scale, it can prevent the rebound or sinking caused by the drilling reaction force and achieve precise adjustment of the detection depth of the detection component 4. In complex strata such as soft and hard interlayers and fractured zones where the depth needs to be frequently adjusted, this structure significantly reduces the time for repeated drilling and measurement, improves work efficiency and data accuracy, and the modular design facilitates quick disassembly and maintenance.

[0042] Example 3:

[0043] Please see Figure 7 As shown, this embodiment is basically the same as the previous embodiment, except that a stabilizing component 6 is provided at the bottom of the base 1. The stabilizing component 6 includes a fixing block 61 fixedly connected to the bottom of the base 1. A first lever 62 and a second lever 64 are rotatably connected to the fixing block 61. A first half gear 63 is fixedly connected to the end of the first lever 62, and a second half gear 65 is fixedly connected to the end of the second lever 64. The stabilizing component 6 is used to fix the equipment to the ground before exploration to prevent displacement due to reaction force or unstable terrain during drilling. The fixing block 61 is fixed to the bottom of the base 1 and serves as the rotation fulcrum of the lever. The first lever 62 and the second lever 64 are respectively meshed by the first half gear 63 and the second half gear 65 to achieve synchronous reverse rotation.

[0044] Specifically, an electric actuator 66 is fixedly connected to the base 1. Two connecting rods 67 are rotatably connected to both the first lever 62 and the second lever 64. A connecting seat 68 is rotatably connected between the two connecting rods 67. A pestle 69 is fixedly connected to the bottom of the connecting seat 68. The electric actuator 66 provides a power source to drive the first lever 62 to rotate, thereby linking the second lever 64. The connecting rods 67 and the connecting seat 68 convert the rotational motion of the levers into the vertical motion of the pestle 69, realizing insertion or removal from the ground. The bottom of the pestle 69 is sharp and can be inserted into the ground to form an anchor, enhancing stability.

[0045] Furthermore, the end of the first lever 62 away from the first half gear 63 is rotatably connected to the output end of the electric actuator 66, the first half gear 63 and the second half gear 65 mesh with each other, and two stabilizing components 6 are provided and arranged symmetrically.

[0046] As can be seen from the above, after the equipment is in place, the electric actuator 66 is activated, which pushes the first lever 62 to rotate around the fixed block 61. The first lever 62 meshes with the second half gear 65 through the first half gear 63, driving the second lever 64 to rotate in the opposite direction. The first lever 62 and the second lever 64 simultaneously move the two connecting rods 67, causing the connecting seat 68 to move down and the spiking rod 69 to be vertically inserted into the ground, forming symmetrical anchoring. The electric actuator 66 can be reversed to pull out the spiking rod 69 and release the fixation. The whole process only takes a few seconds. The meshing of the first half gear 63 and the second half gear 65 ensures that the left and right spiking rods 69 move synchronously, avoiding the machine body from tilting due to single-point force. The pointed cone shape of the spiking rod 69, combined with high thrust, can penetrate deep into unstable strata such as gravel, soft mud, and slopes, significantly suppressing drilling reverse torque and surface slippage, ensuring that the hole inclination is controlled within the specifications. The symmetrically arranged double-stabilized units can also be quickly deployed and retrieved in narrow spaces, improving operational safety and relocation efficiency.
