Description

Technical Field

[0001] This application relates to the field of mineral exploration technology, and more specifically, to a sampling device for monitoring wells in in-situ leaching uranium mines and a sampling vehicle for monitoring wells in mines. Background Technology

[0002] Currently, most existing uranium leaching mine monitoring wells rely on manual lowering and lifting of the sampler. While simple to operate, this method has significant drawbacks. The sampling process is entirely manual, with the lowering depth determined by markings on the wire rope or by experience, leading to considerable errors and difficulty in achieving precise depth sampling. This severely impacts the accuracy of water sample analysis data and the reliability of groundwater flow field assessments. Furthermore, manual operation is inefficient, labor-intensive, and requires multiple operators. During rope winding, the wire rope easily becomes tangled on the drum, accelerating wear, increasing the risk of breakage, and causing inconvenience and safety hazards for subsequent sampling. In addition, the entire sampling device lacks necessary power mechanisms and safety protections, resulting in low automation and failing to meet the practical needs of large-scale, high-frequency monitoring well sampling in uranium leaching mines. Therefore, there is an urgent need for an automated sampling device that can achieve power-driven operation, precise depth determination, automatic rope winding, and significantly improve operational safety and efficiency to ensure the accuracy of environmental monitoring data and the modernization of sampling operations in uranium leaching mines. Utility Model Content

[0003] This application aims to at least address the technical problem in the relevant technology that the existing sampling process relies on manual control, and the depth of descent depends on personnel marking on the wire rope or judging by experience, which has large errors, makes it difficult to achieve accurate depth sampling, and seriously affects the accuracy of water sample analysis data and the reliability of groundwater flow field judgment.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] In a first aspect, this application provides a sampling device for monitoring wells in in-situ leaching uranium mines, comprising: a hydraulic transmission device, which includes a hydraulic pipe, a power input end, an operating lever, and a power output end. The hydraulic pipe is used to connect to an external hydraulic system. The power input end is connected to the hydraulic pipe. The operating lever is located at the power input end to control the on / off state and direction of the hydraulic power. The power output end is connected to the hydraulic pipe. A depth-fixed sampling device, which includes a rope take-up device, a wire rope, a rope arranger, a depth display, and a sampler. The rope take-up device is connected to the power output end of the hydraulic transmission device. The wire rope is wound around the rope take-up device. The rope arranger is driven by the rope take-up device to arrange the wire rope in an orderly manner. The depth display is connected to the rope arranger to display the lowering depth of the wire rope. The sampler is connected to the end of the wire rope. An auxiliary device, which includes a support and a fixed platform. The fixed platform is located on the support. Both the hydraulic transmission device and the depth-fixed sampling device are mounted on the fixed platform.

[0006] The sampling device for monitoring wells in in-situ leaching uranium mines provided in this application achieves powered, precise, and safe sampling operations through the coordinated operation of hydraulic transmission, depth control, and an automatic rope-laying mechanism. In power-driven and control scenarios, the hydraulic transmission device provides power through an external hydraulic source, and the forward and reverse rotation of the power output is controlled by an operating lever, driving the entire sampling process. This transforms traditionally laborious manual operation into a labor-saving and convenient "one-lever" hydraulic control, greatly reducing the labor intensity and operational risks for operators. In precise depth-fixed sampling scenarios, the depth-fixed sampling device, through the mechanical linkage of the rope layer and winder, accurately converts the length of the wire rope into a digital reading on the depth display. Operators can intuitively and accurately read the sampler's descent depth on the ground and control it to precisely stop at the target position of the monitoring well filter, completely solving the core problem of inaccurate manual depth judgment and ensuring the accuracy and representativeness of the sampling. In scenarios requiring orderly wire rope winding and safe operation, the rope-laying mechanism, through a transmission chain and synchronized movement with the rope take-up device, forcibly guides the wire rope to be arranged sequentially and tightly on the take-up device. This fundamentally avoids the risks of rope jamming and breakage that may result from tangled wire ropes, extending equipment lifespan and eliminating safety hazards during subsequent sampling. Simultaneously, protective baffles isolate the transmission components, further enhancing the device's safe operational performance.

[0007] Secondly, this application proposes a mine monitoring well sampling vehicle, including: a uranium leaching mine monitoring well sampling device as described in the above scheme.

[0008] The mine monitoring well sampling vehicle provided in this application integrates the aforementioned sampling device and onboard hydraulic system onto the vehicle body, achieving high mobility and functional completeness in sampling operations. This vehicle is highly mobile and can quickly travel between widely distributed monitoring wells. Its integrated onboard hydraulic system provides a stable and reliable power source for the sampling device, realizing full integration from vehicle movement and power supply to sampling operation, significantly improving the sampling efficiency of large-scale monitoring networks in in-situ leaching uranium mines.

[0020] According to the first aspect of this application, Figure 1 and Figure 2 As shown in the figure, an embodiment of this application provides a sampling device 100 for monitoring wells in uranium leaching mines, comprising: a hydraulic transmission device 110, which includes a hydraulic pipe 112, a power input end 114, an operating lever 116, and a power output end 118. The hydraulic pipe 112 is used to connect to an external hydraulic system. The power input end 114 is connected to the hydraulic pipe 112. The operating lever 116 is disposed at the power input end 114 to control the on / off state and direction of the hydraulic power. The power output end 118 is connected to the hydraulic pipe 112; and a depth-fixed sampling device 120, which includes a rope take-up device 122, a wire rope 124, a rope arranger 126, and a depth display. The device includes a display 128 and a sampler 129. The rope take-up device 122 is connected to the power output end 118 of the hydraulic transmission device 110. The wire rope 124 is wound around the rope take-up device 122. The rope arranger 126 is connected to the rope take-up device 122 to arrange the wire rope 124 in an orderly manner. The depth display 128 is connected to the rope arranger 126 to display the lowering depth of the wire rope 124. The sampler 129 is connected to the end of the wire rope 124. The auxiliary device 130 includes a bracket 132 and a fixed platform 134. The fixed platform 134 is set on the bracket 132. The hydraulic transmission device 110 and the fixed-depth sampling device 120 are both installed on the fixed platform 134.

[0021] like Figure 1 and Figure 2As shown, the in-situ leaching uranium mine monitoring well sampling device 100 provided in this application includes a hydraulic transmission device 110, a fixed-depth sampling device 120, and an auxiliary device 130. The hydraulic transmission device 110 includes a hydraulic pipe 112, a power input end 114, an operating lever 116, and a power output end 118. The hydraulic pipe 112 is used to connect to an external hydraulic system. The power input end 114 is connected to the hydraulic pipe 112. The operating lever 116 is located at the power input end 114 to control the on / off state and direction of the hydraulic power. The power output end 118 is connected to the hydraulic pipe 112. The fixed-depth sampling device 120 includes a rope take-up device 122, a wire rope 124, a rope arranger 126, a depth display 128, and a sampler 129. The rope take-up device 122 is connected to the power output end 118 of the hydraulic transmission device 110. The wire rope 124 is wound around the rope take-up device 122. The rope arranger 126 is drivenly connected to the rope take-up device 122 to arrange the wire rope 124 in an orderly manner. The depth display 128 is connected to the rope arranger 126 to display the lowering depth of the wire rope 124. The sampler 129 is connected to the end of the wire rope 124. The auxiliary device 130 includes a support 132 and a fixed platform 134. The fixed platform 134 is mounted on the support 132. Both the hydraulic transmission device 110 and the fixed-depth sampling device 120 are mounted on the fixed platform 134.

[0022] In this way, the hydraulic transmission device 110 receives and controls external hydraulic power, providing stable and controllable lifting and lowering power for the entire sampling process, thus achieving mechanization of operation. The fixed-depth sampling device 120 utilizes the mechanical linkage principle to accurately convert the linear displacement of the wire rope 124 into the reading of the depth display 128, realizing real-time and visual monitoring of the lowering depth and ensuring the accuracy of the sampling position. At the same time, the rope guide 126 ensures the orderly operation of the wire rope 124 during winding and unwinding, avoiding safety hazards caused by tangling and chaos. The auxiliary device 130 provides an integrated installation platform and a stable support foundation for each functional module, ensuring the overall rigidity and operational stability of the device. This device integrates power drive, depth control, and safety protection, effectively solving the problems of low efficiency, inaccurate depth, high labor intensity, and high safety risks inherent in traditional manual sampling methods.

[0023] Specifically, in-situ leaching uranium mining technology is a green and environmentally friendly new uranium mining process that integrates mining, beneficiation, and smelting. It is currently widely used in uranium mining both domestically and internationally. The main functions of monitoring wells in in-situ leaching uranium mines include comparing test and production data with background values, analyzing and optimizing tests and production, adjusting the balance between pumping and injection, controlling the leaching range, and monitoring leaks to prevent solution loss. The sampling equipment, process, and methods of monitoring wells significantly affect sampling efficiency, and the required depth sampling standards are crucial to the accuracy of water sample analysis data. Deviations in data analysis will prevent effective and timely understanding of groundwater changes. Currently, most in-situ leaching uranium mine monitoring wells use manual lowering and lifting of samplers. While this method is simple to operate, it has significant drawbacks. The sampling process relies entirely on manual control, with the lowering depth depending on markings on the wire rope or judgment based on experience, resulting in significant errors and making it difficult to achieve precise depth sampling. This severely affects the accuracy of water sample analysis data and the reliability of groundwater flow field assessments.

[0024] To address the shortcomings of existing technologies, this application aims to provide a sampling device 100 for monitoring wells in in-situ leaching uranium mines. Through the coordinated operation of hydraulic transmission, depth control, and an automatic rope-laying mechanism, it achieves powered, precise, and safe sampling operations. In power-driven and control scenarios, the hydraulic transmission device 110 provides power through an external hydraulic source, and the operating lever 116 controls the forward and reverse rotation of the power output end 118, driving the entire sampling process. This transforms traditional laborious manual operation into a labor-saving and convenient "one-lever" hydraulic control, significantly reducing the labor intensity and operational risks for operators. In precise depth-fixed sampling scenarios, the depth-fixed sampling device 120, through the mechanical linkage of the rope layer 126 and the rope take-up device 122, accurately converts the length of the wire rope 124 into a digital reading on the depth display 128. Operators can intuitively and accurately read the descent depth of the sampler 129 on the ground and control it to precisely stop at the target position of the monitoring well filter, completely solving the core problem of inaccurate depth judgment by manual methods and ensuring the accuracy and representativeness of the sampling. In the scenario of orderly winding and safe operation of the wire rope 124, the rope-laying mechanism moves synchronously with the rope take-up device 122 via the transmission chain 150, forcibly guiding the wire rope 124 to be arranged sequentially and tightly on the rope take-up device 122. This fundamentally avoids the risk of rope jamming and breakage that may be caused by the wire rope 124 being tangled, extending the equipment's lifespan and eliminating safety hazards during subsequent sampling. At the same time, the protective baffle 160 isolates the transmission components, further improving the safe operation performance of the device.

[0025] Compared with existing technologies, the beneficial effects of the in-situ leaching uranium mine monitoring well sampling device 100 proposed in this application are as follows:

[0026] First, this application achieves the mobility of the sampling device by mounting it on the sampling vehicle frame. Second, this application provides power to the sampling device through the sampling vehicle's hydraulic system, achieving automated power transmission while controlling the transmission speed. Third, this application, through hydraulic power transmission and the addition of an operating lever 116, transforms the operation from two people operating simultaneously to one person operating with a single lever, increasing the number of wells sampled per day from five to eight, significantly improving the efficiency of monitoring well sampling. Fourth, this application, by adding steel... The wire rope 124 winder 126 ensures the orderly winding of the wire rope 124 on the winder 122, avoiding safety risks such as wire rope breakage and tangling caused by messy winding of the wire rope 124; fifth, by adding a depth counter, the depth below the sampling device can be intuitively and accurately determined at the wellhead using a measuring instrument, ensuring sampling accuracy and realizing quantitative determination of the depth; sixth, by modifying the appearance of the sampling vehicle and installing a protective cover for the transmission parts, the safe operation performance and aesthetics of the sampling device are further improved.

[0027] In practical applications, hydraulic hose 112 is made of plastic flexible tubing with a diameter of 13mm. The length of hydraulic hose 112 connecting to the mine monitoring well sampling vehicle 200 is 600mm. The length of hydraulic hose 112 connecting the power input end 114 and the power output end 118 is 400mm. Power is provided by the onboard hydraulic system 220 of the mine monitoring well sampling vehicle 200. The in-situ leaching uranium mine monitoring well sampling device 100 is connected to the mine monitoring well sampling vehicle 200 via hydraulic hose 112. An operating lever 116 is installed at the power input end 114, which acts as a switch, allowing the hydraulic system to operate in both forward and reverse directions, enabling the sampling device to be turned on and off, as well as released and lifted. Specific options can be selected based on actual usage conditions and will not be listed here.

[0028] In some embodiments, optionally, such as Figure 1 and Figure 3 As shown, bracket 132 has a trapezoidal structure.

[0029] Specifically, such as Figure 1 As shown, the support frame 132 adopts a trapezoidal structure that is narrower at the top and wider at the bottom. This structural design significantly lowers the overall center of gravity of the device and increases the bottom support area, thereby providing stronger anti-tipping stability during the movement or operation of the sampling vehicle and ensuring the safety and reliability of the device. The sloping sides of the trapezoid also help optimize stress distribution, improve the load-bearing capacity and structural rigidity of the support frame 132, and provide a solid and stable foundation for the fixed platform 134 and all components mounted on top of it. At the same time, this structure also facilitates manufacturing and processing and matches the sampling vehicle frame for installation.

[0030] In practical applications, bracket 132 is an iron bracket with an anti-corrosion paint finish. The bracket 132 is 800mm high and 900mm long. The specific selection can be made according to the actual use situation, and will not be listed here.

[0031] In some embodiments, optionally, such as Figure 1 and Figure 2 As shown, the fixed platform 134 is a square with a side length of 900mm.

[0032] Specifically, such as Figure 2 As shown, the fixed platform 134 adopts a square structure with a side length of 900mm. This size design provides ample and rationally arranged installation space for the various components of the hydraulic transmission device 110 and the constant depth sampling device 120, ensuring the compactness and functionality of the overall equipment structure. The square shape maximizes the effective working area within a limited space, while the symmetrical structure facilitates the centered arrangement and balanced installation of the equipment on the platform, helping to maintain the stability of the entire device's center of gravity. This size specification has also been verified by mechanical calculations, providing reliable support for various loads generated during device operation.

[0033] In specific applications, the fixed platform 134 is an iron fixed platform with an anti-corrosion paint coating on its surface. The fixed platform 134 is square with a side length of 900mm. The specific choice can be made according to the actual use situation, and will not be listed here.

[0034] In some embodiments, optionally, such as Figure 2 As shown, the depth display 128 is a mechanical digital display.

[0035] Specifically, such as Figure 2 As shown, the depth display 128 employs a purely mechanical digital display device. Its core working principle involves the rotational motion of the rope guide 126 driving a built-in gear transmission mechanism, precisely converting the linear displacement of the wire rope 124 into the rotation of a digital wheel, thereby directly and in real-time displaying the lowering depth of the sampler 129 in digital form. This mechanical structure requires no power supply, its counting accuracy is directly guaranteed by mechanical transmission, and it has strong anti-interference capabilities, making it particularly suitable for stable and reliable operation in the complex, humid, and dusty environments of mines. It not only eliminates errors caused by manual measurement and estimation, achieving quantitative and visual lowering depth measurement, but also allows operators to accurately determine the position of the sampler 129 from a safe location away from the mine entrance, significantly improving sampling accuracy and operational safety.

[0036] In specific applications, the depth display 128 is a mechanical digital display device connected to the rope arranger 126. The digital changes are realized through the operation of the rope arranger 126, thereby displaying the real-time descent depth. The specific choice can be made according to the actual use situation, and will not be listed here.

[0037] In some embodiments, optionally, such as Figure 2 As shown, the rope retractor 122 is a cylindrical structure with a radius of 100mm and a length of 300mm.

[0038] Specifically, such as Figure 2 As shown, the rope take-up device 122 is designed as a cylindrical structure with a radius of 100mm and a length of 300mm. This cylindrical structure ensures uniform stress distribution on the wire rope 124 during winding, effectively reducing fatigue damage caused by excessive local bending and extending its service life. Its compact size design matches the output torque of the hydraulic transmission device 110, ensuring smooth and efficient power transmission during rope take-up and unwinding.

[0039] In practical applications, the rope take-up device 122 has a cylindrical structure with a radius of 100mm and a length of 300mm. The side guards on both sides of the take-up device 122 extend 50mm above the cylinder, effectively preventing the wire rope 124 from detaching from the take-up device 122 during winding, thus ensuring operational safety and reliability. This structure achieves both functionality and lightweight and miniaturization of the device. Specific options can be selected based on actual usage conditions and will not be listed here.

[0040] In some embodiments, optionally, such as Figure 2 As shown, the diameter of wire rope 124 is 5mm to 10mm.

[0041] Specifically, such as Figure 2 As shown, the diameter of the wire rope 124 ranges from 5mm to 10mm. The design of this diameter range comprehensively considers the strength requirements, flexibility needs, and compatibility with the structure of the rope take-up device 122 during sampling operations. A 5mm diameter wire rope 124 offers good flexibility, facilitating tight winding on the take-up device 122, while also meeting the sampling strength requirements for most monitoring well depths, achieving lightweight and economic efficiency. When facing deeper wells or requiring the lifting of a heavier sampler 129, such as when obtaining a full-capacity sample, a thicker diameter wire rope 124 can be used, with its higher breaking strength and wear resistance to ensure operational safety and reliability. This range design allows the device to flexibly adapt to different operating conditions, ensuring core functions while providing optional flexibility for practical applications through the parametric design of key components.

[0042] In practical applications, the diameter of the 124 wire rope can be set to 5mm, 6mm, 7mm, 8mm, 9.5mm, or 10mm. The specific choice depends on the actual usage and will not be listed here.

[0043] In some embodiments, optionally, such as Figure 2 As shown, the sampler 129 is a Bayer tube made of stainless steel, and a check valve is provided at the lower end of the Bayer tube.

[0044] Specifically, such as Figure 2 As shown, the sampler 129 is made of stainless steel Bayler tubing, with a check valve installed at its lower end. The stainless steel sampler 129 possesses excellent corrosion resistance and structural strength, enabling it to withstand long-term erosion by corrosive ions that may be present in groundwater, ensuring the durability of the equipment and the purity of the sampled water, and preventing metal ion contamination. The check valve at the lower end of the sampler 129 is a key component ensuring the accuracy of depth sampling. Its working principle is as follows: during the lowering of the Bayler tubing, the valve disc remains open due to water pressure, allowing water to flow smoothly; when the sampler 129 reaches the predetermined depth and begins to rise, the valve disc quickly closes under its own weight and water pressure, forming a sealed chamber. This accurately captures and retains the water sample at that depth, effectively preventing the mixing of water samples from different layers and ensuring the representativeness of the sample and the authenticity of the test data.

[0045] In practical applications, sampler 129 is a special Bellerion tube for groundwater sampling, made of stainless steel, with a diameter of 45mm, a length of 740mm, and a capacity of approximately 1L. Specific selections can be made based on actual usage conditions and will not be listed here.

[0046] In some embodiments, optionally, such as Figure 2 As shown, the fixed-depth sampling device 120 also includes a guide rope tube 140, through which the steel wire rope 124 is lowered and raised.

[0047] Specifically, the guide tube 140 is fixedly installed on the fixed platform 134, with its axis aligned with the center of the monitoring wellhead. The wire rope 124, after being led out from the rope guide 126, passes precisely through the inner hole of the guide tube 140 and connects to the sampler 129 downhole. The core function of the guide tube 140 is to provide a stable and smooth guiding channel for the winding and unwinding of the wire rope 124. Its smooth inner wall greatly reduces friction, collision, or scratching between the wire rope 124 and surrounding fixed structures during high-speed winding and unwinding, effectively protecting the surface of the wire rope 124 and extending its service life. Simultaneously, it constrains the movement trajectory of the wire rope 124, ensuring that the sampler 129 is always accurately lowered and raised vertically, preventing it from swinging significantly inside the wellbore and colliding with the well wall. This protects the well casing facilities of the monitoring well and ensures that the sampler 129 can accurately reach the predetermined depth, further improving sampling accuracy and operational safety.

[0048] In practical applications, the sampler 129 is a dedicated Bellerion tube for groundwater sampling, equipped with a check valve at the lower end. The sampler 129 is connected to the wire rope 124 and is lowered and raised via the guide tube 140, preventing friction between the wire rope 124 and the support 132 and fixed platform 134. Hydraulic power drives the sampler 129 to be lowered and raised, with a lowering speed of approximately 2 m / s and a raising speed of 1.5 m / s. The specific selection can be based on actual usage conditions and will not be listed here.

[0049] In some embodiments, optionally, such as Figure 2 As shown, the fixed-depth sampling device 120 also includes: a transmission chain 150, which connects the rope take-up device 122 and the rope arranger 126; and a protective baffle 160, which is disposed outside the transmission chain 150.

[0050] Specifically, such as Figure 2 As shown, the fixed-depth sampling device 120 also includes a drive chain 150 and a protective baffle 160. The drive chain 150 is tightly meshed with the sprockets of the rope take-up device 122 and the rope arranger 126, synchronously and precisely transmitting the rotational power generated by the hydraulically driven rope take-up device 122 to the rope arranger 126, ensuring the matching of their rotational speeds and the synchronization of their movements. The protective baffle 160 is made of metal or high-strength engineering plastic and is tightly fitted over the drive chain 150 and sprockets by bolts or clips, forming a fully enclosed or semi-enclosed safety isolation space. This design fundamentally eliminates the possibility of operators' hands, clothing, or other debris coming into contact with or getting caught in the high-speed moving chain during equipment operation, effectively preventing mechanical injury accidents and greatly improving the operational safety of the device. At the same time, the protective baffle 160 also serves to prevent dust and mud splashes, helping to protect the transmission components, extend their service life, and maintain the equipment in good working condition.

[0051] According to the second aspect of this application, such as Figure 3 As shown, a mine monitoring well sampling vehicle 200 is also proposed, including: a uranium leaching mine monitoring well sampling device 100 as described in the above embodiment, a vehicle body 210 and an on-board hydraulic system 220. The on-board hydraulic system 220 is mounted on the vehicle body 210 and is connected to the hydraulic transmission device 110 of the uranium leaching mine monitoring well sampling device 100 via a hydraulic pipe 112.

[0052] Specifically, such as Figure 3As shown, the vehicle body 210 provides a mobile carrier for the entire sampling system. The sampling device 100 for monitoring wells in in-situ leaching uranium mines is securely mounted and fixed to the rear of the vehicle body 210 or a dedicated work platform via the bracket 132 in its auxiliary device 130. The on-board hydraulic system 220 is integrated into the chassis or engine compartment of the vehicle body 210, and it is quickly connected to the hydraulic pipe 112 of the hydraulic transmission device 110 of the sampling device through hydraulic oil pipes, forming a complete hydraulic power circuit. The advantages of this design are: First, it improves the mobility of sampling operations, allowing the vehicle to easily shuttle between various monitoring wells widely distributed in the mining area, greatly improving the coverage efficiency of sampling work. Second, it realizes the internalization and specialization of power supply. The on-board hydraulic system 220, as a stable and reliable power source, ensures that the sampling device can obtain continuous and uniform power output under different working conditions, eliminating the dependence on external power on site and improving the overall efficiency, professionalism, and safety of large-scale environmental monitoring sampling operations in in-situ leaching uranium mines.

[0053] In practical applications, the sampling steps of the mine monitoring well sampling vehicle 200 are as follows:

[0054] (1) Connect the hydraulic pipe 112 of the in-situ leaching uranium mine monitoring well sampling device 100 to the hydraulic system of the mine monitoring well sampling vehicle 200;

[0055] (2) Park the mine monitoring well sampling vehicle 200 in a suitable position, open the monitoring well cover, and ensure that the sampler 129 can be placed directly above the monitoring well opening;

[0056] (3) Check that the mine monitoring well sampling vehicle 200 is parked safely and that the in-situ leaching uranium mining monitoring well sampling device 100 is safe.

[0057] (4) Determine the depth of the sampling monitoring well and the location of the filter, and check that the depth display 128 is zeroed;

[0058] (5) Move the operating lever 116 of the power input terminal 114 downwards, and the sampling device 100 of the monitoring well of the fixed-depth leaching uranium mine starts to work. The wire rope 124 drives the sampler 129 to be lowered, and at the same time the depth display 128 starts to display the lowering depth.

[0059] (6) When the depth display 128 shows that the sampler 129 has been lowered to a depth of about 2m to 3m above the monitoring well filter, operate the operating lever 116 to stop the lowering of the sampler 129;
