Technical Field

[0001] This invention relates to the field of geological and mineral exploration technology, specifically a sampling device for deep geological and mineral exploration. Background Technology

[0002] Geological exploration refers to the process of systematically collecting geological information of rock and soil masses through on-site investigation, measurement, and testing. Its core objective is to provide reliable data support for engineering construction, resource development, and other purposes.

[0003] Sampling equipment is a crucial tool for obtaining firsthand physical data in geological exploration, playing a vital role throughout the entire exploration process. However, existing sampling equipment suffers from limitations such as limited sampling depth, low core recovery rates (especially in fractured strata where cores are easily lost or contaminated), and the inability to monitor formation parameters in real time during sampling, leading to data lag and the inability to achieve continuous sampling and synchronous acquisition of formation information, thus failing to meet the accuracy requirements for deep mineral exploration. Therefore, this invention provides a sampling device for deep mineral exploration. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a sampling device for deep geological exploration to solve the aforementioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sampling device for deep geological exploration, comprising a support mechanism, a lifting mechanism, a sampling mechanism, and a spraying mechanism;

[0006] The support mechanism includes two symmetrically arranged support plates. The upper ends of the two support plates are movably connected to a support plate via a fixed shaft. A positioning seat is detachably installed on the upper end of the support plate.

[0007] The lifting mechanism includes multiple hydraulic cylinders installed inside the support plate. A movable plate is installed at the lower end of the hydraulic cylinder, and movable plates are installed at both ends of the movable plate. The outer side of the movable plate extends to the outer side of the support plate, and the extension section is sleeved with a limit plate.

[0008] The sampling mechanism includes a drive motor, and the lower end of the drive motor is connected to a first sampling component and a second sampling component. The first sampling component and the second sampling component are connected by a connecting cylinder, and both the first sampling component and the second sampling component consist of a rotating shaft and multiple sets of sampling slots installed on the circumferential surface of the rotating shaft.

[0009] The spraying mechanism includes a water tank installed on the upper end of the movable plate. An inlet pipe is installed on the output side of the water tank. The output side of the water tank is divided into two paths, and each output path is connected to a water pump through a connecting pipe. The output side of the water pump is connected to a spraying pipe.

[0010] It also includes a monitoring unit, which consists of a temperature sensor, a pressure sensor, a resistivity probe, and a gamma ray detector embedded in the sidewall of the rotating shaft.

[0011] Preferably, the inner side of the support plate is provided with a through groove, and the movable plate is installed in the through groove.

[0012] Preferably, the support plate has limiting grooves on both sides, and the upper end of the support plate is movably connected to the limiting grooves via a fixed shaft.

[0013] Preferably, the circumferential surfaces at both ends of the fixed shaft are connected to fastening nuts via threads.

[0014] Preferably, the positioning seat has an internal mounting hole, the hydraulic cylinder is interference-fitted with the mounting hole, and a snap-fit ​​block is installed at the lower end of the positioning seat, and a snap-fit ​​groove is provided at the upper end of the support plate, with the snap-fit ​​block snapping into the snap-fit ​​groove.

[0019] Preferably, it further includes: a control terminal disposed on the upper end of the positioning seat, the control terminal being connected to the hydraulic cylinder, the water pump and the monitoring unit via a signal connection.

[0020] Beneficial effects

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] The support mechanism is designed to be flexible and adaptable. By adjusting the position of the fixed shaft in the movable groove and locking it with a fastening nut, it can quickly adapt to survey sites with different terrain features. The combination of symmetrical support plates and adjustable angle support plates effectively distributes the weight of the equipment and reduces ground pressure. Compared with traditional fixed support structures, the stability is significantly improved, and reliable support can be achieved in rugged or soft terrain.

[0023] The lifting mechanism is driven by a hydraulic cylinder and guided by a limit plate. The lifting process is smooth and without deviation. It can accurately adapt to the depth requirements of different geological explorations. Compared with manual or mechanical lifting methods, it has higher adjustment accuracy and faster response speed, providing stable height support for the sampling mechanism.

[0024] The sampling mechanism adopts a dual-collection component synchronous operation mode. The drive motor can adaptively adjust the output torque according to the hardness of the formation. Combined with the high-speed rotating sampling tank, it can efficiently collect multi-depth, high-fidelity mineral and rock samples. Compared with a single collection component, the sampling efficiency is improved and the sample integrity is better.

[0025] The spray mechanism and monitoring unit work together to achieve intelligent temperature control and dust reduction. The temperature sensor provides real-time feedback on the shaft temperature, and the control terminal automatically adjusts the spray power. This effectively reduces the high temperature of sampling friction, extends the life of components, and inhibits dust diffusion. Compared with the traditional fixed spray method, it has lower energy consumption and is more environmentally friendly.

[0026] The monitoring unit integrates multi-dimensional sensing devices to monitor shaft temperature, sampling resistance, formation resistivity, and radioactive elements in real time. It can not only provide early warning of equipment failure and protect core components, but also simultaneously acquire formation characteristic data, providing real-time basis for mineral layer location and type judgment. Compared with the single parameter monitoring of existing technologies, the data dimensions are more comprehensive, and the accuracy of exploration is greatly improved. Attached Figure Description

[0034] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1-6 A sampling device for deep geological exploration includes a support mechanism 1, a lifting mechanism 2, a sampling mechanism 3, and a spraying mechanism 4.

[0036] The support mechanism 1 includes two symmetrically arranged support plates 11. The upper ends of the two support plates 11 are movably connected to a support plate 13 through a fixed shaft 12. A positioning seat 14 is detachably installed on the upper end of the support plate 13.

[0037] The support plate 11 provides stable support, and its symmetrical arrangement evenly distributes the overall weight of the equipment, reducing pressure on the ground and further improving stability. The fixed shaft 12 ensures the connection stability between the support plate 11 and the support plate 13, and also allows for angle adjustment between the support plate 11 and the support plate 13 to meet the usage requirements under different conditions. The support plate 11 has an internal movable groove for the fixed shaft 12 to move. By changing the position of the fixed shaft 12 inside the movable groove, the usage angle between the support plate 11 and the support plate 13 can be changed to meet the usage requirements of different sites. The support plate 13 supports the positioning seat 14, and the positioning seat 14 ensures the installation stability of the hydraulic cylinder 21 and the control terminal 6.

[0038] The lifting mechanism 2 includes multiple hydraulic cylinders 21 installed inside the support plate 13. A movable plate 22 is installed at the lower end of the hydraulic cylinder 21. Moving plates 23 are installed at both ends of the movable plate 22. The outer side of the moving plate 23 extends to the outer side of the support plate 11, and the extension section is sleeved with a limit plate 24.

[0039] The hydraulic cylinder 21 is used to drive the movable plate 22 to move vertically, thereby driving the moving plates 23 at both ends to move up and down synchronously along the outer side of the support plate 11; the limiting plate 24 can limit the movement trajectory of the moving plate 23 to prevent it from deviating or shaking, and ensure the stability of the lifting process; through the extension and retraction adjustment of the hydraulic cylinder 21, the overall height of the lifting mechanism 2 can be flexibly changed, thereby adapting to the geological exploration needs at different depths and providing reliable height support for the precise sampling operation of the sampling mechanism 3.

[0040] The sampling mechanism 3 includes a drive motor 31. The lower end of the drive motor 31 is connected to a first sampling component 32 and a second sampling component 33. The first sampling component 32 and the second sampling component 33 are connected by a connecting cylinder 34. Both the first sampling component 32 and the second sampling component 33 are composed of a rotating shaft 35 and multiple sampling slots 36 installed on the circumferential surface of the rotating shaft 35.

[0041] The drive motor 31 outputs stable rotational power to drive the shaft 35 of the first acquisition component 32 to rotate at high speed. The power is then synchronously transmitted to the shaft 35 of the second acquisition component 33 through the connecting cylinder 34, causing the sampling slots 36 of the two acquisition components to rotate synchronously with the shaft 35. With the vertical lifting cooperation of the lifting mechanism 2, the rotating sampling slots 36 can cut into deep strata, efficiently cutting and accommodating mineral and rock samples at different depths, meeting the needs of deep geological exploration for multi-depth, high-fidelity sample collection. At the same time, the drive motor 31 can adaptively adjust the output torque according to the hardness of the strata, ensuring that sampling operations can still be completed stably in hard or complex strata environments, effectively improving the environmental adaptability and sampling efficiency of the equipment.

[0042] The spraying mechanism 4 includes a water tank 41 installed on the upper end of the movable plate 22. A water inlet pipe 42 is installed on the output side of the water tank 41. The output side of the water tank 41 is divided into two paths, and each output side is connected to a water pump 44 through a connecting pipe 43. The output side of the water pump 44 is connected to a spray pipe 45.

[0043] The water tank 41 stores clean water or special coolant for cooling and dust suppression during sampling operations, providing a stable liquid source for subsequent spraying processes. Its large-capacity design can meet the needs of long-term continuous sampling without frequent liquid replenishment, improving operational efficiency. The water tank 41 is equipped with a liquid level sensor, which can monitor the remaining liquid level in real time and feed the data back to the control terminal 6, so that operators can promptly grasp the timing of water replenishment and avoid interruption of the spraying process due to water shortage. The water inlet pipe 42 is used to achieve rapid water replenishment, further enhancing the continuous operation capability of the equipment. The water pump 44 is used to extract the water source inside the water tank 41 through the connecting pipe 43 and spray it precisely onto the surface of the high-speed rotating first collection component 32 and second collection component 33 through the spray pipe 45, effectively reducing the high temperature generated by the friction between the sampling tank 36 and the ground, preventing components from wearing or deforming due to overheating, and extending the service life of the sampling mechanism. At the same time, the water mist formed by the spray can suppress the dust raised during the sampling process, reducing the impact on the working environment and the health of operators, and improving the overall safety and environmental protection of the operation.

[0044] It also includes a monitoring unit 5, which consists of a temperature sensor 51, a pressure sensor 52, a resistivity probe 53, and a gamma ray detector 54 embedded in the side wall of the rotating shaft 35.

[0045] Temperature sensor 51 is used to monitor the surface temperature change of the rotating shaft 35 in real time during the high-speed rotation sampling process, and transmits the collected temperature data to the control terminal 6 in real time. When the temperature of the rotating shaft exceeds the preset threshold, the control terminal 6 will automatically trigger the water pump 44 of the spray mechanism 4 to increase the output power, increase the liquid spray volume of the spray pipe 45, and enhance the cooling effect. If the temperature drops back to the safe range, the water pump power will be adjusted to the normal level to achieve precise temperature control. This not only prevents the rotating shaft 35 from thermal deformation or material performance degradation due to long-term high-temperature operation, but also optimizes energy consumption in conjunction with the spray system, ensuring that the sampling mechanism 3 can continue to operate efficiently in a stable temperature environment. Pressure sensor 52 is used to sense the resistance pressure of the sampling tank 36 when it cuts into the stratum and the radial load borne by the rotating shaft 35 during rotation, and feeds the pressure data back to the control terminal 6 in real time. When the pressure value exceeds the preset safety threshold (such as when encountering hard rock or foreign objects), the control terminal will automatically trigger the water pump 44 of the spray mechanism 4 to increase the output power, increase the liquid spray volume of the spray pipe 45, and enhance the cooling effect. If the temperature drops back to the safe range, the water pump power will be adjusted to the normal level to achieve precise temperature control. This not only prevents the rotating shaft 35 from thermal deformation or material performance degradation due to long-term high-temperature operation, but also optimizes energy consumption in conjunction with the spray system, ensuring that the sampling mechanism 3 can continue to operate efficiently in a stable temperature environment. Terminal 6 will immediately issue instructions to reduce the output speed of the drive motor 31 or increase the torque to prevent the sampling tank 36 from cracking due to overload or the shaft 35 from deforming. If the pressure value is lower than the normal sampling range, the drive motor speed will be appropriately increased to ensure sampling efficiency. The resistivity probe 53 is used to detect the resistivity changes of the strata in the sampling area in real time. By analyzing the resistivity differences of strata at different depths, mineral and non-mineral strata can be quickly distinguished, and the type and distribution range of mineral strata can be preliminarily determined. The gamma ray detector 54 can capture the intensity of gamma rays released by natural radioactive elements in the strata. Combined with the preset radioactivity threshold, it can identify strata containing radioactive minerals such as uranium and thorium, providing key basis for the accurate positioning of deep geological resources. All data collected by the monitoring unit 5 is synchronized to the control terminal 6 in real time through the wireless transmission module. Operators can intuitively view the curves of various parameters through the terminal interface, dynamically adjust the equipment operating status, and realize intelligent and precise control of sampling operations.

[0046] Specifically, a through groove is provided on the inner side of the support plate 11, and the movable plate 23 is installed in the through groove; the through groove provides a path and guidance for the movement of the movable plate 23, ensuring the stability of the movement.

[0047] Specifically, the support plate 13 has limit grooves on both sides, and the upper end of the support plate 11 is movably connected to the limit grooves through the fixed shaft 12; by setting the limit grooves, the support plate 13 can be moved, ensuring the stability of the adjustment.

[0048] Specifically, the circumferential surfaces at both ends of the fixed shaft 12 are connected to fastening nuts 15 by threads; under the action of the fastening nuts 15, the fixed shaft 12 can be positioned and fixed at different positions.

[0049] Specifically, the positioning seat 14 has an internal mounting hole, and the hydraulic cylinder 21 is interference-fitted with the mounting hole. Under the action of the mounting hole, the connection stability between the positioning seat 14 and the hydraulic cylinder 21 can be guaranteed. Furthermore, a snap-fit ​​block is installed at the lower end of the positioning seat 14, and a snap-fit ​​groove is opened at the upper end of the support plate 13. The snap-fit ​​block snaps into the snap-fit ​​groove. With the cooperation of the snap-fit ​​block and the snap-fit ​​groove, the connection stability between the support plate 13 and the positioning seat 14 can be guaranteed, and it is easy to disassemble and facilitate assembly.

[0050] Specifically, the movable plate 22 has a limiting hole inside, and the output shaft of the hydraulic cylinder 21 is interference-fitted with the limiting hole; under the action of the limiting hole, the connection stability between the hydraulic cylinder 21 and the movable plate 22 can be guaranteed, thereby ensuring the actual use effect.

[0051] Specifically, the limiting plate 24 has a positioning groove inside that matches the size of the moving plate 23, and the moving plate 23 passes through the positioning groove; the positioning groove can ensure the connection stability between the limiting plate 24 and the moving plate 23, and is easy to disassemble and combine for installation.

[0052] Specifically, threaded connections are provided on the circumferential surfaces of the lower end of the upper rotating shaft 35 and the upper end of the lower rotating shaft 35, and the internal thread is provided on the connecting cylinder 34. The rotating shaft 35 and the connecting cylinder 34 are connected by threads. The threaded connection facilitates the quick assembly and disassembly of the first collection component 32 and the second collection component 33, which is convenient for subsequent cleaning of the sampling tank 36, replacement of worn parts, or overall maintenance, effectively shortening maintenance time and improving the operation and maintenance efficiency of the equipment. This connection method has a simple and reliable structure, and can be assembled and disassembled without special tools, reducing the difficulty of on-site operation and further enhancing the practicality and convenience of the equipment in complex field environments.

[0053] Specifically, the water pump 44 is fixedly installed at the lower end of the support plate 13, and both the connecting pipe 43 and the spray pipe 45 are made of stainless steel corrugated pipe. The stainless steel corrugated pipe has excellent corrosion resistance and can effectively resist the erosion of common acid and alkali substances, mineral solutions and dust in deep mining environments, preventing the pipe from rusting or perforating due to long-term contact with corrosive media, and ensuring the sealing and stability of liquid transmission. Its excellent flexibility and fatigue resistance can adapt to the bending, stretching and vibration deformation of the pipe during the frequent lifting and lowering of the sampling mechanism 3 driven by the lifting mechanism 2, without cracking or breaking, ensuring the continuous and reliable operation of the spray system. At the same time, the inner wall of the stainless steel corrugated pipe is smooth and the fluid resistance is small, which can reduce the power loss of the water pump 44 and improve the liquid transmission efficiency. Moreover, its connection parts adopt a sealed structure design, which can effectively prevent liquid leakage, further enhancing the operational stability and environmental protection of the spray mechanism 4.

[0054] Specifically, it also includes: a control terminal 6 set on the upper end of the positioning seat 14, which is connected to the hydraulic cylinder 21, water pump 44 and monitoring unit 5 via signal; the control terminal 6 adopts an industrial-grade touch screen display, integrating functions such as equipment operation parameter monitoring, operation command input, and fault alarm prompts. Its built-in intelligent control algorithm can automatically coordinate the collaborative work of the lifting mechanism 2, sampling mechanism 3 and spraying mechanism 4 based on the multi-dimensional data fed back by the monitoring unit 5. In addition, the control terminal 6 supports data storage and export functions, which can completely record various parameters and stratigraphic feature data during the sampling process and generate a draft of the exploration report, greatly reducing the workload of subsequent data processing and improving the output efficiency of exploration results.

[0055] Working principle:

[0056] According to the terrain features of the survey site, the operator adjusts the position of the fixed shaft 12 in the movable groove of the support plate 11 and tightens the fastening nut 15 to unfold the support mechanism 1 to a stable support state, ensuring that the overall equipment is evenly stressed; sufficient clean water or special coolant is added to the water tank 41 through the water inlet pipe 42, and operation instructions such as target sampling depth, formation hardness safety threshold, and spray cooling parameters are input on the touch screen of the control terminal 6.

[0057] After the operation is started, the control terminal 6 sends a signal to the hydraulic cylinder 21, driving the movable plate 22 to move the moving plate 23 smoothly down along the through groove in the support plate 11, and simultaneously pulling the sampling mechanism 3 vertically into the stratum to the preset depth; the drive motor 31 then starts, outputting rotational power to be transmitted to the first collection component 32 through the rotating shaft 35, and simultaneously driving the second collection component 33 to rotate through the connecting cylinder 34. The sampling trough rotates at high speed with the rotating shaft to cut into the stratum, efficiently cutting and accommodating mineral and rock samples at different depths.

[0058] During the sampling process, the monitoring unit 5 works continuously. The temperature sensor 51 monitors the temperature of the rotating shaft 35 in real time. If the temperature exceeds the threshold, the control terminal 6 automatically increases the output power of the water pump 44 to enhance the spray cooling. The pressure sensor 52 senses that the sampling resistance exceeds the limit, and the drive motor 31 adaptively adjusts the torque or reduces the speed to avoid damage to the components. The stratigraphic data fed back by the resistivity probe 53 and the gamma ray detector 54 provide a basis for real-time judgment of the mineral layer type and distribution.

[0059] The spraying mechanism 4 sprays water mist synchronously to reduce the high temperature generated by sampling friction and suppress dust diffusion. After sampling is completed, the hydraulic cylinder 21 drives the movable plate 22 to rise, causing the sampling mechanism 3 to detach from the stratum. The control terminal 6 automatically stores the entire operation data and generates a draft exploration report. After the operator exports the data, the equipment is turned off, completing this deep geological exploration sampling operation.
