Description

Technical Field

[0001] The present invention relates to the technical field of geological and mineral exploration, and in particular to a positioning-type geological and mineral exploration rock sample sampling device and method. Background Art

[0002] In the field of geological and mineral exploration, accurately and comprehensively obtaining rock samples from different strata is the core work for revealing the evolution laws of geological structures and accurately evaluating the distribution and reserves of mineral resources. As geological exploration work gradually expands to complex geological areas and deep strata, more stringent requirements are placed on the accuracy, diversity and efficiency of rock sample sampling. Different strata contain different geological information and mineral resources. Only by collecting samples comprehensively and accurately can a reliable basis be provided for geological research and mineral development.

[0003] However, the existing rock sampling technology for geological and mineral exploration has many limitations. Traditional sampling devices often find it difficult to flexibly adjust sampling strategies based on real-time geological changes. When faced with complex and changeable geological structures, such as fault and fold development areas, due to the lack of real-time perception and analysis capabilities of geological changes, it is difficult to accurately judge the boundaries and characteristics of different strata, resulting in deviations in sampling positions and an inability to effectively obtain representative samples.

[0073] Step 2: When the pressure slider 107 is pushed downward to the lowest point, the central control box 113 is used to shut down the positioning type geological and mineral exploration rock sample sampling device, and then another extension tube 112 is spliced ​​between the extension tube 112 and the docking pipe joint 110 using a tool.

[0074] Step 3: Repeat the work of steps 1 and 2 to gradually increase the advancement depth of the sampler 2. When the sampler 2 encounters a rock layer, the central control box 113 will obtain rock layer information through the pressure monitoring structure 7 and the torque detector 8. Then the central control box 113 controls the working power of the pressure water pump based on the collected information. The pressure water pump stops sampling when it is working at high power, and starts sampling when it is working at low power.

[0075] Step 4: Use the central control box 113 to control the positioning type geological and mineral exploration rock sample sampling device to lift the sampler 2, and then take out the rock sample inside the sampler 2.

[0076] Working principle: First, use the central control box 113 to start the sampling program, and then the central control box 113 controls the sampling motor 109 to run, and then the sampling motor 109 rotates with the adapter 814, and then the adapter 814 rotates with the arc slide 812, and then the arc slide 812 presses the second pressure sensor 813 on the inner wall of the arc chamber 811, and then the second pressure sensor 813 detects the pressure value in real time and sends the data to the central control box 113, and the pressure value can reflect the torque value borne by the extension tube 112 and the sampler 2, and then the inner wall of the arc chamber 811 is subjected to force and drives the short-circuit column 802 to rotate, and then the short-circuit column 802 rotates with the docking connector 110 through the short-circuit rod 801, and then the docking connector 110 rotates with the sampler 2, and then the sampling is completed. The sampler 2 rotates with the drill structure 3, and then the central control box 113 controls the pressure water pump to work, and then the water enters the cylindrical tube 804 from the water inlet pipe 805, and then the water passes through the fixed square hole 803, the docking pipe head 110, the first joint pipe 111, the extension pipe 112, the second joint pipe 201, the installation pipe 601, and the water hole 602 into the annular cavity between the sample storage tube 608 and the sampling outer tube 204, and then the water inside the annular cavity is ejected through the jet hole 504, the gap between the fixed ring 501 and the driving short tube 505, the central through hole 302, and the reduced diameter hole 307. At the same time, the water inside the annular cavity exerts pressure on the annular piston 503 under the action of the pressure difference, and then the annular piston 503 moves downward under the action of pressure and squeezes the strain spring 502, and the strain spring 502 is elastically compressed, and the elastic potential energy increases. Then the annular piston 503 moves downward with the driving rod 507 through the driving short tube 505. Then the driving rod 507 slides downward on the chamfered slope 402 and applies a turning force to the middle inclined plate 303. Then the middle inclined plate 303 is turned toward the middle and the tension spring 403 is pulled. The tension spring 403 is elastically stretched, and the elastic potential energy increases. Then the middle inclined plates 303 are docked together. At this time, the power of the pressure water pump reaches the maximum power preset in the central control box 113, and the drill bit structure 3 is in the drilling mode. Then the central control box 113 controls the pressure motor 106 to run, and then the pressure motor 106 rotates with the pressure screw 105. Then the pressure screw 105 is threadedly engaged with the internal threaded hole 706. The action of drives the linkage horizontal plate 705 to move downward, and then the linkage horizontal plate 705 moves downward with the pressure slider 107 through the lead-out short column 704, the limit disc 703, and the diameter-expanding ring groove 702, and then the pressure slider 107 moves downward with the sampler 2 through the oblique box 108, the sampling motor 109, the torque detector 8, and the extension tube 112, and then the sampler 2 moves downward with the drill bit structure 3, and then the drill bit structure 3 drills into the ground and forms a sampling hole, and then the linkage horizontal plate 705 moves downward with the limit disc 703 relative to the pressure slider 107 through the lead-out short column 704, and then the limit disc 703 presses on the first pressure sensor 707, and the first pressure sensor 707 detects the feed pressure in real time and sends the data to the central control box 113,Then the first pressure sensor 707 applies pressure to the pressure slider 107, and then the central control box 113 controls the speed of the pressure motor 106. The speed of the pressure motor 106 increases, the detection data of the first pressure sensor 707 increases, and the feed pressure increases. Conversely, the feed pressure decreases. Then the central control box 113 analyzes the formation characteristics and matches the feed pressure according to the torque detected by the second pressure sensor 813. Then the central control box 113 controls the speed of the pressure motor 106 according to the matched feed pressure, so that the feed pressure detected by the first pressure sensor 707 is adapted to the matched feed pressure. Then the formation is cut and crushed by the drill bit structure 3 to form small particles. Then the water sprayed from the reduced diameter hole 307 carries the small particles and flows upward along the sampling hole and out from the top of the sampling hole. The liquid flows out from the end opening, and then the pressure slider 107 moves downward to the lowest point, and then the central control box 113 shuts down the pressure motor 106 and the sampling motor 109, and then uses a tool to separate the connecting pipe 110 from the extension pipe 112, and then uses the central control box 113 to control the pressure motor 106 to run in the reverse direction until the pressure slider 107 moves upward to the highest point, and then takes out another extension pipe 112, and splices this extension pipe 112 with the connecting pipe 110, and then uses the central control box 113 to control the pressure motor 106 to run in the forward direction, and then this extension pipe 112 gradually moves downward, and then controls the sampling motor 109 to rotate, and then the sampling motor 109 rotates with this extension pipe 112, and then makes the bottom end of this extension pipe 112 Align with the first joint tube 111 at the top of the previous extension tube 112, then the extension tube 112 moves downward while rotating, and then the first joint tube 111 enters the interior of the extension tube 112 in a threaded manner to complete the docking, and then use the central control box 113 to start the sampling program, and then the sampler 2 and the drill bit structure 3 continue to drill downward, and then repeat the above steps to gradually deepen the sampling hole. When the formation characteristics of the drill bit structure 3 change, the resistance to the drill bit structure 3 changes, and then the torque value detected by the second pressure sensor 813 changes, and then the central control box 113 controls the feed pressure according to the real-time torque value. Then, when the torque value detected by the second pressure sensor 813 meets the rock characteristics, the central control box 11 3. The pressure motor 106 is controlled to stop and the power of the pressure water pump is controlled to decrease. Then, the pressure on the annular piston 503 is reduced. Then, the annular piston 503 moves upward relative to the sampling outer cylinder 204 under the action of the elastic force of the strain spring 502. Then, the annular piston 503 moves upward with the driving rod 507 through the driving short tube 505. Then, the central inclined plate 303 is turned outward under the elastic tension of the tension spring 403. Then, the central inclined plate 303 is opened outward until the power of the pressure water pump is equal to the minimum power value preset in the central control box 113. At this time, the sampling mode is entered. Then, the central control box 113 controls the pressure motor 106 to run. Then, the second drill bit 306, the third drill bit 308, and the fourth drill bit 309 in circular motion continue to drill downward.The first drill bit 304 cuts and trims the rock in the middle area of ​​the sampling hole, and then the rock in the middle area of ​​the sampling hole is formed into a rock rod. Then, as the drill bit structure 3 drills, the rock rod passes upward through the guide tapered hole 611 and is inserted into the sample tube 608. The mounting groove 609 applies a damping force to the rock rod, so that the rock rod will not move relative to the sample tube 608 in a natural state. Then, the distance drilled downward by the drill bit structure 3 meets the preset requirements inside the central control box 113. Then, the central control box 113 controls the pressure motor 106 to stop and controls the pressure water pump to run at high power. Then, the force on the annular piston 503 increases, and then the annular piston 503 drives the short tube 505 and the driving The rod 507 and the chamfered bevel 402 apply a turning force to the middle inclined plate 303, and then the middle inclined plates 303 are closed together to enter the drilling mode. During this process, the sampling outer cylinder 204 rotates with the first drill bit 304 through the embedded column 301 and the middle inclined plate 303 to cut the rock rod. When the end of the middle inclined plate 303 is docked, the rock rod is cut off, and the rock rod remaining in the sample storage tube 608 is the sample taken. The first sampling is completed. After that, the central control box 113 controls the pressure motor 106 to operate, so that the sampler 2 and the drill bit structure 3 continue to advance downward. When the formation characteristics change again in the future, the sampling is carried out according to the principle of the first sampling. For subsequent sampling, until the number of samples meets the requirements or the sample storage tube 608 is filled with samples, the central control box 113 is used to control the pressure motor 106 to reverse the pressure motor 106, and then the extension tube 112 moves upward with the sampler 2. When the pressure slider 107 moves upward to the highest point, the central control box 113 controls the pressure motor 106 to stop, and then uses a tool to clamp the second extension tube 112 from the top, and then remove the first extension tube 112 from the top, and then use the central control box 113 to control the docking pipe head 110 to move downward, and then splice the docking pipe head 110 with the extension tube 112 at the top of the sampling hole. Then, use the central control box 113 to control the docking connector 110 to move upward. Repeat the above steps, removing the extension tube 112 in sequence until the sampler 2 is taken out. Then remove the sealing end cap 202 and the sample storage tube 608. Then, use the internal threaded sleeve to splice the threaded joint 607. Then, rotate the threaded joint 607 and the sealing disk 606 through the internal threaded sleeve. Then, separate the sealing disk 606 from the receiving groove 604. Then, apply pressure to the internal threaded sleeve. Then, the internal threaded sleeve pushes the rock sample out of the sample storage tube 608 through the threaded joint 607 and the sealing disk 606. At this point, sampling is complete.
