Description

Technical Field

[0001] The present application belongs to the field of geological exploration sampling technology, and specifically relates to a uranium geological exploration sampling device and method. Background Art

[0002] In uranium geological exploration, uranium cores retrieved from underground are crucial for determining uranium reserves and their spatial distribution. However, current uranium core sampling suffers from the following drawbacks: Conventional uranium core testing and cutting equipment often operate independently. Manual point-by-point measurement is often used to determine uranium content in cores, which is inefficient and difficult to accurately determine the distribution of uranium content at different locations due to the inability to fully scan the core. Furthermore, due to a lack of accurate knowledge of uranium content distribution, the cutting process is often random or crude, making it difficult to directly distinguish uranium content at different locations on the uranium core in the field. Consequently, precise sampling of areas with different uranium content in the field is impossible, resulting in the waste of large amounts of core with high uranium content. Furthermore, the core samples obtained lack a true representation of uranium resources and geological characteristics, impacting the accuracy of uranium exploration and the reliability of resource assessments.

[0003] Therefore, there is an urgent need to develop a uranium geological exploration sampling device and method that can effectively cut and sample the removed cores. Summary of the Invention

[0054] A specific embodiment of the present invention, as Figures 1 to 7 As shown, a uranium geological exploration sampling device is disclosed, comprising:

[0055] The core supporting mechanism 10 is used to support the core, where the core refers to the core containing uranium ore obtained from the target layer in the uranium exploration area;

[0056] The detection slide rail mechanism 20 is arranged on one side of the core supporting mechanism 10 and is arranged parallel to the core supporting mechanism 10;

[0057] The uranium content detection mechanism 30 is movably arranged on the detection slide rail mechanism 20;

[0058] A core rotation mechanism 40 is used to drive the core to rotate;

[0059] The cutting mechanism 50 is used for cutting the core.

[0060] In one optional embodiment, the cutting mechanism 50 comprises a multi-axis robotic arm and a cutter. The cutter on the cutter is used to cut the core, which is typically cylindrical. The cutting mechanism 50 is moved by a cutting track 501, allowing it to be moved to any position on the core for cutting. The cutting mechanism 50 utilizes a multi-axis robotic arm, and through the linkage of three linear axes (X, Y, and Z) and three rotational axes, it achieves precise positioning of the cutter in three-dimensional space.

[0061] During cutting, the core obtained by drilling is placed axially on the core supporting mechanism 10, and the core is adjusted to a preset detection height; the uranium content detection mechanism 30 is driven to move on the detection slide mechanism 20 to the starting detection end of the core, and the uranium content detection mechanism 30 is vertically close to the outer surface of the core to a preset detection distance; the uranium content detection mechanism 30 is controlled to perform uniform linear motion, so that the uranium content detection mechanism 30 performs continuous line scanning from one end of the core to the other end, and synchronously collects uranium content data of each axial point on the outer surface of the core; after completing a single axial scan, the core rotation mechanism 40 drives the core to rotate around the axis by a preset angle, and repeats the axial scanning and detection steps until the core is scanned 360° around the entire circumference to obtain the core uranium content scanning result, and the cutting mechanism is used to cut the target area based on the core uranium content scanning result.

[0062] In some optional embodiments, the core supporting mechanism 10 includes a supporting rail 101, a supporting sliding seat 102, a supporting lifting motor 103 and a supporting base 104; wherein, the number of the supporting rails 101 is two groups, two groups of parallel supporting rails 101, each group of supporting rails 101 is provided with at least six independently operating supporting sliding seats 102, the supporting sliding seats 102 on one group of supporting rails 101 are paired with the supporting sliding seats 102 on the other group of supporting rails 101, and the two supporting sliding seats 102 in each pair are respectively located on both sides of the core to lift the core, and the supporting sliding seats 102 can move on the supporting rails 101; the supporting lifting motor 103 is connected to the supporting sliding seat 102 and can be extended and retracted in the vertical direction; the supporting base 104 is connected to the telescopic end of the supporting lifting motor 103.

[0063] In this embodiment, the core is placed on a core support mechanism 10 consisting of two sets of parallel support rails 101 and multiple support slides 102. The support slides 102 on each set of support rails 101 operate independently and, through a paired arrangement, are positioned on either side of the core to support it. The support slides 102 can be moved on the support rails 101 to adjust their position to accommodate cores of varying lengths. A support lift motor 103 is connected to the support slides 102 and, by extending and retracting in the vertical direction, drives the support base 104 up or down, thereby adjusting the core to a predetermined testing height.

[0064] Importantly, this embodiment is provided with at least six pairs of bearing slides 102. For example, when cutting a core, the core has three parts: the target area core 70, the left core of the target area core 70, and the right core of the target area. A pair of bearing slides 102 is provided at both ends below the target area core 70, the left core of the target area core 70, and the right core of the target area. The bearing bases 104 on the bearing slides 102 respectively support the target area core 70, the left core of the target area core 70, and the right core of the target area. After the cutting mechanism 50 completes the cutting, the left core of the target area core 70 moves toward the left side away from the target area core 70 with the cooperation of the bearing base 104 and the bearing slide 102, and the right core of the target area core 70 moves toward the right side away from the target area core 70 with the cooperation of the bearing base 104 and the bearing slide 102. In this way, the left core of the target area core 70 and the right core of the target area are sufficiently spaced from the target area core 70 , so as to facilitate the subsequent operation of the core rotating mechanism 40 .

[0065] The bearing sliding seat 102 includes a slider structure and a built-in drive motor. The built-in drive motor drives the slider structure to move on the bearing rail 101. The bearing sliding seat 102 is an existing technology. The bearing sliding seat 102 is also provided with necessary transmission structures, such as gears and other structures. The sliding seats mentioned below can adopt a structure similar to the bearing sliding seat 102.

[0066] In some optional embodiments, the core rotation mechanism 40 includes a rotating track 401 and multiple groups of clamping arms, where the two clamping arms in one group are distributed on both sides of a rotating track 401, and the clamping directions of the two clamping arms in one group are arranged relative to each other. The rotating track 401 is arranged above the core supporting mechanism 10 and is parallel to the core supporting mechanism 10.

[0067] In some optional embodiments, the clamping arm includes a rotating sliding seat 403, a rotating base and four abutments 406; wherein the rotating sliding seat 403 is driven and connected to the rotating track 401; a three-axis mechanical telescopic arm 404 is connected to the rotating sliding seat 403, and the three-axis mechanical telescopic arm 404 includes three linear axes of X, Y, and Z and three rotating axes; the rotating base is connected to the three-axis mechanical telescopic arm 404, and the rotating base can move in three-dimensional space; the three-axis mechanical telescopic arm 404 is used to drive the rotating base to move in the x direction, y direction and z direction; four abutments 406 are connected to the rotating base, and the four abutments 406 are arranged in a ring, and the angle between two adjacent abutments 406 is ninety degrees. At the same time, the four abutments 406 just form a square and are respectively located at each corner of this square. The length of the abutment 406 is greater than the diameter of the cutting knife of the cutting mechanism 50, and there is a gap between two adjacent abutments 406.

[0068] In this embodiment, the rotating track 401 of the core rotating mechanism 40 is suspended above the core supporting mechanism 10, and the rotating track 401 is arranged parallel to the axis of the core. A group of two clamping arms are distributed on both sides of the rotating track 401, and the clamping directions are opposite. Exemplarily, the core rotating mechanism 40 includes two rotating tracks 401 and two groups of clamping arms, each group includes two clamping arms, and two clamping arms are provided on each rotating track 401. Specifically, the clamping arms include two groups, and the two clamping arms of one group are located at the outermost side of the rotating track 401, and are used to rotate the whole core before cutting. The inner group of clamping arms on the rotating track 401 is used to clamp the target area core 70 after cutting. When clamping, the clamping arm will move to the gap between the left core of the target area core 70 and the target area core 70, and move to the gap between the right core of the target area and the target area core 70, respectively clamping at both ends of the target area core 70.

[0069] In this embodiment, the rotating track 401 and the cutting track 501 are both suspended. Optionally, the rotating track 401 and the cutting track 501 can be suspended in the air or supported by a support. Figure 1 As shown, the rotating track 401 and the cutting track 501 are suspended in the air, and both ends of the rotating track 401 and the cutting track 501 are provided with a suspension seat, which is connected to a suspension support mechanism (not shown in the figure).

[0070] Considering that some tests require that the core sample be shaped into a semi-cylindrical or quarter-cylindrical shape, for example, the target area core 70 is further cut into four equal parts to obtain one or more cores with a higher uranium content among the four cores.

[0071] First, the cutting mechanism 50 switches from cutting along the y-direction to cutting along the x-direction. The rotating slide 403 moves along the rotating track 401, driving the connected three-axis mechanical telescopic arm 404 and the rotating base to move, bringing the four abutments 406 closer to the core. The abutments 406 are arranged in a ring, with adjacent abutments 406 forming a square at 90-degree angles, one at each corner of the square. The length of the abutments 406 is greater than the diameter of the cutting blades of the cutting mechanism 50, and there is a gap between adjacent abutments 406, ensuring smooth cutting. After the abutments 406 contact and secure the core, the cutting blade advances downward, entering through the gap between the two upper abutments 406 and cutting the target area of the core 70. The two abutments 406 are arranged symmetrically about the core's axis. After cutting is complete, the rotating base, via its internal direct-drive motor and drive gear train, drives the portion of the rotating head 405 located within the rotating barrel 402 to rotate, thereby rotating the core 90 degrees around its axis. After the rotation is completed, the cutting mechanism 50 remains in the same position and advances again to cut the core, forming a cross-shaped blade, and the target area core 70 is evenly divided into four parts. At the same time, the four abutment members 406 just abut the center of the two ends of each core.

[0072] In some optional embodiments, the detection slide mechanism 20 includes a detection track 201 and a detection slide seat 202. The detection track 201 is arranged on one side of the core support mechanism 10 and is arranged parallel to the core support mechanism 10. The detection slide seat 202 is driven and connected to the detection track 201. By arranging the detection track 201 of the detection slide mechanism 20 parallel to the core support mechanism 10, the detection slide seat 202 is driven by a built-in servo motor, causing the detection slide seat 202 to perform linear motion along the detection track 201. The uranium content detection mechanism 30 is fixed to the detection slide seat 202 and moves synchronously therewith to achieve linear scanning detection of the core axial direction.

[0073] In some optional embodiments, the uranium content detection mechanism 30 includes a fixed bracket 301, a uranium content detection telescopic motor 302, and a uranium content detection instrument 303. The fixed bracket 301 is connected to the detection slide 202, the uranium content detection telescopic motor 302 is connected to the fixed bracket 301, and the uranium content detection instrument 303 is connected to the telescopic end of the uranium content detection telescopic motor 302. The telescopic motor 302 can drive the uranium content detection instrument 303 close to the surface of the core. By connecting the fixed bracket 301 of the uranium content detection mechanism 30 to the detection slide 202 of the detection slide mechanism 20, when the detection slide 202 moves on the detection track 201 to the core to be tested, the telescopic motor 302 is activated. The telescopic motor 302 drives the uranium content detection instrument 303, connected to the telescopic end, toward the core until the uranium content detection instrument 303 is close to the outer surface of the core and reaches a preset detection distance. Subsequently, the detection sliding seat 202 drives the uranium content detection mechanism 30 to move along the detection track 201, so that the uranium content detection instrument 303 scans and detects the side wall of the core. During this process, the uranium content detection telescopic motor 302 continuously maintains a preset distance between the uranium content detection instrument 303 and the core surface to ensure the accuracy of the detection data.

[0074] It should be noted that the uranium content detection instrument in this embodiment uses the same principle as existing uranium ore analysis and testing instruments and can be implemented using existing uranium ore analyzers. For example, uranium content detection instrument 303 can be a radiation detector (model 3013b), a portable X-ray fluorescence spectrometer, a portable gamma spectrometer, or other analytical instruments known in the art that can perform uranium content detection.

[0075] In some optional embodiments, the rotating surface of the rotating base is perpendicular to the axis of the core. The rotating base includes a rotating cylinder 402, a rotating head 405, a direct drive motor, and a drive gear set. The rotating cylinder 402 is connected to the three-axis mechanical telescopic arm 404. The rotating head 405 is rotatably connected to one end of the rotating cylinder 402. Part of the rotating head 405 is internally disposed within the rotating cylinder 402. The portion of the rotating head 405 internally disposed within the rotating cylinder 402 is provided with teeth and grooves. The direct drive motor is disposed within the rotating cylinder 402 and drives the portion of the rotating head 405 internally disposed within the rotating cylinder 402 to rotate via the drive gear set. The rotating head 405 is connected to an abutment 406, which is located at the edge of the rotating head 405. When the direct drive motor is started, the direct drive motor drives the rotating head 405 to rotate within the rotating cylinder 402. The rotation of the rotating head 405 drives the abutment 406 and the core fixed to the abutment 406 to rotate about the core axis.

[0076] In some optional embodiments, the abutting portion of abutment 406 is connected to a rubber column, the diameter of which is larger than that of abutment 406. When the core rotation mechanism 40 secures the core via abutment 406, the rubber column in the abutting portion of abutment 406 first contacts the core surface. Because the rubber column has a larger diameter than the abutment 406 and is elastic, it deforms upon contact with the core surface, increasing the contact area and frictional force.

[0077] In some optional embodiments, the uranium geological exploration sampling equipment further includes a packaging mechanism 60 for marking each fan-shaped column and packaging the four fan-shaped columns when cutting the core into four equal fan-shaped columns (i.e., quarter cylinders).

[0078] Exemplarily, the packing mechanism 60 includes a packing motor 601, a cross plate 602, a pulling belt 603 and a locking structure. The packing motor 601 is arranged at the bottom of the rotating cylinder 402. The bottom center of the rotating cylinder 402 and the center of the rotating head 405 are both provided with insertion holes. The driving end of the packing motor 601 is provided with the insertion hole. The cross plate 602 is inserted into the driving end of the packing motor 601, and the packing motor 601 and the cross plate 602 are connected and released from each other through the locking structure. Each wing plate of the cross plate 602 is located between two adjacent abutment members 406. The pulling belt 603 is provided on one of the wing plates of the cross plate 602. The cross plate 602 can be inserted into the cross-shaped incision of the core cut into four equal parts.

[0079] After the core is cut into four equal fan-shaped columns, the packing motor 601 drives the cross plate 602 to insert it into the cross-shaped incision of the core, so that the wings of the cross plate 602 are tightly plugged into the core incision. After insertion is complete, the locking mechanism is released, and the driving end of the packing motor 601 is separated from the cross plate 602. Then, the pull strap 603 installed on one of the wings of the cross plate 602 is manually pulled out and wrapped around the outer circumference of the four fan-shaped columns. After the pull strap 603 has been wrapped around multiple times, the two ends can be connected and fixed by means such as heat fusion or snap fasteners, firmly binding the four fan-shaped columns together. The length of the wing plate can be set to be slightly longer than the radius of the core by 1mm-3mm, or the edge of one end of the wing plate can be exactly flush with the outer wall of the core. The edge of the wing plate can be set with different colors or markings to distinguish the four cores. At the same time, the configuration of the cross plate 602 ensures that the cores are tightly packed together, preventing the four cores from being scattered. The cores form a whole, which is convenient for subsequent storage and transportation.

[0080] In one of the optional embodiments, the locking structure includes an electromagnetic locking device, which includes an electromagnetic coil assembly, a locking pin assembly, a lock hole structure, a shell and a base; wherein the electromagnetic coil assembly includes a hollow coil wound with enameled copper wire, a magnetic shell and a skeleton, which is used to generate a magnetic field when electricity is turned on; the locking pin assembly includes a cylindrical steel locking pin body, a reset spring and a guide sleeve, the front end of the locking pin body is conical or hemispherical, the reset spring is sleeved on the locking pin body, and the guide sleeve and the locking pin body are gap-fitted; the lock hole structure is arranged in the circumferential direction of the connecting hole of the cross plate 602 that can be inserted by the packaging motor 601, and 3-4 blind holes are evenly distributed; the shell and the base are used to integrate the electromagnetic coil assembly, the guide sleeve and the circuit interface; wherein the electromagnetic coil assembly is installed in the shell and the base, the locking pin assembly is inserted in the guide sleeve and is arranged corresponding to the electromagnetic coil assembly, the shell and the base are connected to the driving shaft of the packaging motor 601 by bolts, and the locking pin body can be extended and inserted into the lock hole structure to achieve locking.

[0081] Optionally, the locking structure can also be achieved by setting a limiting protrusion on the driving end of the packing motor 601 when the driving end of the packing motor 601 is interlaced with the cross plate 602. When the packing motor 601 pushes the cross plate 602 into the core incision, the cross plate 602 is restricted from moving toward the packing motor 601. When the cross plate 602 enters the core incision, friction is generated between the cross plate 602 and the core, and the cross plate 602 moves away from the packing motor 601, thereby disengaging from the packing motor 601.

[0082] In some optional embodiments, the packaging mechanism 60 includes a pulling mechanism, which includes a first pulling rail 604, a first pulling slide 605, a second pulling rail 606, a first lifting motor 607, a second lifting motor 608, and a main magnet 609. The pulling end of the draw belt 603 is provided with a secondary magnet 610. The first pulling rail 604 is arranged along the x-direction. The first pulling slide 605 is driven and connected to the first pulling rail 604. The second pulling rail 606 is arranged along the y-direction. The second pulling rail 606 is provided with a second pulling slide 611. The first lifting motor 607 is connected to the second pulling slide 611. The second lifting motor 608 is connected to the driving end of the first lifting motor 607. The first lifting motor 607 is driven along the z-direction, and the second lifting motor 608 drives the main magnet 609 along the y-direction. The main magnet 609 can be raised to the top of one side wing of the corresponding cross plate 602 under the drive of the first lifting motor 607. A secondary magnet 610 is provided at the pulling end of the pulling belt 603, and the secondary magnet 610 is located outside the cross plate 602, that is, the secondary magnet 610 is plugged into the opening opened at the side edge end of the cross plate 602. When the cross plate 602 is inserted into the rock core, part of the secondary magnet 610 is still outside the incision of the rock core, so that the main magnet 609 can be driven by the second lifting motor 608. The main magnet 609 can move to directly above the secondary magnet 610, and the main magnet 609 and the secondary magnet 610 are in contact with each other and adsorbed together. After the two are adsorbed together, the first pulling-out sliding seat 605 moves in the direction away from the rock core, pulling the pulling belt 603 out to a predetermined length, and then the rotating head 405 is controlled to drive the abutment 406 to rotate, and the abutment 406 causes the four parts of the rock core to rotate, and at the same time the pulling belt 603 is wound around the four parts of the rock core, and the first pulling-out sliding seat 605 moves in coordination until the winding is completed. Under the action of the pulling force, the main magnet 609 and the auxiliary magnet 610 are separated from each other, and the auxiliary magnet 610 is fixed on the rock core or the pulling belt 603 is fixed after cutting.

[0083] In this embodiment, the pulling-out mechanism includes two groups, which are respectively arranged on opposite sides of the target area core 70. After the cutting knife vertically cuts the target area core, a vertical incision is formed. At this time, the core is rotated and the vertical cutting becomes a horizontal incision. Before the cutting knife vertically cuts the core again, the pulling-out mechanism on both sides can be controlled to operate so that the second lifting motor 608 drives the main magnet 609 to be inserted into the horizontal incision, which can support the upper and lower parts of the core when the cutting knife vertically cuts the core again.

[0084] The present application also provides a uranium ore geological exploration sampling method, using the aforementioned uranium ore geological exploration sampling equipment; specifically, the uranium ore geological exploration sampling method includes the following steps:

[0085] Place the drilled core axially on the core support mechanism 10 and adjust the core to a preset detection height;

[0086] The uranium content detection mechanism 30 is driven to move on the detection slide mechanism 20 to the starting detection end of the core, and the uranium content detection mechanism 30 is vertically close to the outer surface of the core to a preset detection distance;

[0087] Controlling the uranium content detection mechanism 30 to perform uniform linear motion, so that the uranium content detection mechanism 30 performs continuous line scanning from one end of the core to the other end, and synchronously collects uranium content data at each axial point on the outer surface of the core;

[0088] After completing a single axial scan, the core rotation mechanism 40 drives the core to rotate around the axis by a preset angle and repeats the axial scanning detection steps until a full 360° scan of the core is completed to obtain the core uranium content scan result;

[0089] According to the scanning results of the core uranium content, the core is cut using a cutting mechanism.

[0090] When the core is cut using the cutting mechanism, the cutting mechanism 50 can be manually moved to the position where the core needs to be cut, or it can be automatically moved to the position where the core needs to be cut according to a set program.

[0091] In one of the optional embodiments, after the uranium content detection mechanism 30 completes the scanning detection, the geological staff can manually move the cutting mechanism 50 to the position where cutting is required based on the uranium content distribution scanning result data obtained by the uranium content detection mechanism 30, and then start the cutting machine mechanism to cut the target position.

[0092] In another optional embodiment, the cutting device can also automatically cut the core according to a set program through automatic control. For example, after the uranium content detection mechanism 30 completes the scanning detection, the uranium content detection mechanism 30 can transmit the detected uranium content scanning result data to the data processing system. The data processing system integrates the scanning result data, constructs a three-dimensional uranium content distribution model of the core, identifies the uranium content peak area or the user-specified target area through threshold screening, generates a cutting path plan containing spatial coordinates, and transmits the cutting path plan to the control system. The control system drives the cutting mechanism 50's cutting blade to the target area according to the cutting path plan to complete the cutting of the target area. Therefore, based on the cutting path plan generated by the core uranium content distribution data, the cutting machine is accurately moved to the target cutting position, ensuring that the cutting machine's cutting blade and the spatial position of the core area to be cut are precisely matched. It should be noted that the control system and data processing system in this embodiment can be implemented using existing technologies. In other words, the above-mentioned automatic cutting operation steps can be realized by using existing control system technology and data processing technology to realize automatic control of the cutting equipment.

[0093] Compared to the prior art, the uranium geological exploration sampling equipment and method provided in this embodiment integrates a core support mechanism, a detection slide mechanism, a uranium content detection mechanism, a core rotation mechanism, and a cutting mechanism. Through the coordinated operation of the core support mechanism, the detection slide mechanism, the uranium content detection mechanism, the core rotation mechanism, and the cutting mechanism, it is possible to accurately locate areas of high uranium content, low uranium content, and uranium-free uranium cores, and control the cutting mechanism to perform targeted cutting of the target areas. Compared to traditional random or extensive cutting methods, it is possible to obtain uranium core cutting samples with different uranium ore contents at different locations in a targeted manner. The obtained uranium core samples are more targeted, and on-site sampling is more scientific, effectively avoiding ineffective cutting and ensuring that the obtained core cutting samples can truly reflect the geological characteristics of the uranium ore and the enrichment of uranium resources.

[0094] The above specific implementation methods further illustrate the purpose, technical solutions and beneficial effects of this application in detail. It should be understood that the above are only specific implementation methods of this application and are not intended to limit the scope of protection of this application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this application should be included in the scope of protection of this application.
