Description

Technical Field

[0001] This utility model belongs to the field of mine monitoring technology, and specifically relates to a rare earth mine slope monitoring device. Background Technology

[0002] Rare earth minerals are important strategic resources, and their mining is mostly carried out in open-pit mining. As a key structure in open-pit mining, slopes are easily affected by multiple factors such as geological structure, mining disturbance, and climate conditions, and are prone to gradual deformation or even sudden instability. This can not only cause mining operations to be interrupted, but may also lead to safety accidents. Therefore, real-time and accurate monitoring of slope displacement is the core link to ensure the safety of rare earth mining.

[0003] However, existing slope displacement monitoring relies on wire-type displacement gauges to capture minute deformations. Rare earth mining sites have environmental conditions such as rainfall and water accumulation that can affect the internal electrical components of the monitoring device. Operating the monitoring device in such an environment can easily lead to corrosion and damage to the internal components. Utility Model Content

[0004] In view of the technical problems existing in the background art, this application provides a rare earth mine slope monitoring device, including a box body, a plurality of pull-wire displacement gauges are provided inside the box body, the pull-wire displacement gauges are housed at the bottom of the box body, and the upper part of the box body contains internal components, the internal components are physically isolated from the pull-wire displacement gauges by a partition plate.

[0005] In some embodiments, the isolation plate has a central hole in its middle, and the information transmission interface of the internal component extends out from the central hole.

[0006] In some embodiments, the insulating sheet is recessed upward at the central hole to form a raised platform.

[0007] In some embodiments, the wire displacement gauge is arranged around the bottom of the box and is attached to the inner wall of the box.

[0008] In some embodiments, a monitoring line is connected to the wire displacement gauge, and the end of the monitoring line away from the wire displacement gauge is set along an arc trajectory.

[0009] In some embodiments, the pull-wire displacement gauge is connected to a monitoring line, the monitoring line is inclined to the ground, and the angle between the monitoring line and the first axial direction is an acute angle. The first direction is the length extension direction of the left and right sides of the upper surface of the box when the monitoring line is inclined to the ground.

[0010] In some embodiments, the pull-wire displacement gauge is connected to a monitoring line, and the angle between the monitoring line and the second axial direction is an acute angle; The second direction is the length extension direction of the upper and lower side edges of the upper surface of the box.

[0011] In some implementations, the internal components include a GPS module, an audible and visual alarm, a transceiver, a lithium battery, and a repeater.

[0012] In some embodiments, the side surface of the wire displacement gauge is connected to the lower surface of the isolation plate by a gasket, the side surface of the wire displacement gauge is perpendicular to the ground, and the top surface of the wire displacement gauge does not contact the bottom surface of the isolation plate.

[0013] In some embodiments, the gasket has a perforation, and the isolation plate also has a corresponding perforation, through which the wire displacement gauge is electrically connected to the internal component.

[0014] This application provides a rare earth mine slope monitoring device, including a housing containing multiple pull-wire displacement gauges. The pull-wire displacement gauges are housed at the bottom of the housing, while the upper part of the housing houses internal components. The internal components are physically isolated from the pull-wire displacement gauges by insulating plates. The structural design of the housing effectively resists the influence of external environmental factors such as large diurnal temperature differences, frequent rainfall, and vibrations from ore mining in rare earth mining areas, providing a dry and safe working environment for the internal components and preventing damage from environmental erosion or external impacts. Orienting the pull-wire displacement gauges at the bottom of the housing avoids the installation space of the upper internal components, preventing interference between the monitoring wires and the wiring and interfaces of the internal components. It also shortens the length of the monitoring wires within the housing, reducing measurement errors caused by wire bending. Furthermore, it concentrates rainwater seeping into the housing at the bottom, preventing it from spreading upwards and eroding the upper internal components, thus creating the first waterproof barrier for the internal components. The housing is divided into an upper and lower containment chamber by an insulating sheet. The internal components are placed in the upper containment chamber and the pull-wire displacement gauge is placed in the lower containment chamber, forming an additional waterproof measure. This can prevent liquid that seeps into the lower containment chamber from invading upwards, completely avoiding contact between the internal components and the liquid, and further ensuring the stable operation of the internal components.

[0026] In some implementations, refer to Figure 1A rare earth mine slope monitoring device includes a box 10, which contains a plurality of pull-wire displacement gauges 20. The pull-wire displacement gauges 20 are housed at the bottom of the box 10, and the upper part of the box 10 contains internal components. The internal components are physically isolated from the pull-wire displacement gauges 20 by an isolation plate 30. Specifically, the outermost layer of this device is a housing 10, which is used to isolate the external environment, house the internal components, and provide a dry and safe electrical working environment inside. Mining areas have large temperature differences between day and night, frequent rain, and may be accompanied by vibrations from ore mining. The overall structure of the housing 10 can effectively resist these external environmental influences and prevent damage to internal components due to environmental erosion or external impact. Multiple pull-wire displacement gauges 20 are housed inside the housing 10 and are oriented at the bottom of the housing 10. On the one hand, the pull-wire displacement gauge 20 needs to be connected to a monitoring line 40 at the measuring head. The slight movement of the slope is captured by the stretching and contraction displacement changes of the monitoring line 40. When monitoring the slope in a mine, the monitoring line 40 often needs to cross a certain distance and be inclined to connect to the slope monitoring point. Leading the monitoring line 40 out from the bottom of the housing 10 can directly avoid the installation space of the upper internal components, avoid the monitoring line 40 from getting tangled or interfering with the wiring and interfaces of the internal components, and at the same time shorten the length of the monitoring line 40 in the housing 10, reducing measurement errors caused by wire bending.

[0027] The internal components, including electrical elements, are housed in the upper part of the housing 10. This is because the monitoring line 40 of the wire displacement gauge 20 is often installed outdoors and has a large span. In most cases, the monitoring line 40 is inclined to the housing 10. This means that if there is standing water or rainwater in the outdoor environment, the water may adhere to the monitoring line 40 and move along it under the influence of gravity. Eventually, it will seep into the housing 10 through the gap at the connection between the measuring head of the wire displacement gauge 20 and the housing 10. If the wire displacement gauge 20 and the internal components are in the same space, this seeping water will not only wet the mechanical parts of the wire displacement gauge 20 but also wet the internal components. As electrical components, the internal components are prone to short circuits, contact corrosion, and other malfunctions once they come into contact with water, leading to interrupted data acquisition, distorted monitoring data, or even direct damage to the components. Therefore, by placing the wire displacement gauge 20 at the bottom of the box 10, the infiltrated rainwater can be concentrated in the lower part of the box 10 and cannot spread upward to the internal components of the upper part of the box 10. This creates the first waterproof barrier for the internal components from a spatial layout perspective, ensuring their stable operation.

[0028] Furthermore, the internal components are physically isolated from the wire displacement gauge 20 by the isolation plate 30. That is, the isolation plate 30 itself functions to divide the interior of the housing 10 into an upper cavity and a lower cavity. The upper cavity houses the internal components, and the lower cavity houses the wire displacement gauge 20. This forms an additional waterproof measure between the wire displacement gauge 20 and the internal components. This structure ensures that even if a small amount of rainwater breaks through the gap between the monitoring line 40 and the measuring head and enters the lower cavity, the water can only flow along the lower surface of the isolation plate 30 and cannot cross the isolation plate 30 to invade the upper cavity. This is because there is no obvious gap between the edge of the isolation plate 30 and the inner wall of the housing 10, which can effectively block the penetration of liquid and prevent the lower surface of the internal components from contacting the external liquid, thus blocking the path of water erosion of the internal components.

[0029] This application provides a rare earth mine slope monitoring device, including a housing 10. Multiple pull-wire displacement gauges 20 are installed inside the housing 10, with the gauges housed at the bottom. Internal components are housed in the upper part of the housing 10, and these components are physically isolated from the pull-wire displacement gauges 20 by an isolation plate 30. The structural design of the housing 10 effectively resists the influence of external environmental factors such as large diurnal temperature differences, frequent rainfall, and ore mining vibrations in rare earth mining areas, providing a dry and safe working environment for the internal components and preventing damage due to environmental erosion or external impact. Orienting the pull-wire displacement gauges 20 to the bottom of the housing 10 avoids the installation space of the upper internal components, preventing interference between the monitoring wires 40 and the wiring and interfaces of the internal components. It also shortens the length of the monitoring wires 40 within the housing 10, reducing measurement errors caused by wire bending. Furthermore, it concentrates rainwater seeping into the housing 10 at the bottom, preventing it from spreading upwards and eroding the upper internal components, thus creating the first waterproof barrier for the internal components. The housing 10 is divided into an upper and lower containment chamber by an isolation plate 30. The internal components are placed in the upper chamber, and the wire-operated displacement gauge 20 is placed in the lower chamber, forming an additional waterproof measure. This prevents liquid seeping into the lower chamber from intruding upwards, completely avoiding contact between the internal components and the liquid, and further ensuring the stable operation of the internal components. The overall structure closely matches the core requirements of rare earth mine slope monitoring, effectively solving the problems of protection and measurement accuracy in complex mining environments, ensuring reliable operation of the device and accurate monitoring data.

[0030] In some implementations, refer to Figure 1The isolation plate 30 has a central hole 31 in its middle, through which the information transmission interface of the internal components extends. Specifically, the information transmission interface of the internal components is a key component for data interaction between the device and external equipment. It needs to be connected to external data acquisition devices, remote communication modules, or power supply lines. If the interface is only located in the upper cavity, the external lines need to pass through additional openings on the top or side of the housing 10. This would not only compromise the overall sealing of the housing 10, allowing rainwater and mine dust to enter the upper cavity through the new openings, but also make on-site wiring difficult. By extending the interface from the central hole 31, the external lines can directly connect to the interface in the lower area of ​​the housing 10 without the need for drilling holes in other parts of the housing 10, thus preserving the sealing integrity of the housing 10 and avoiding the environmental interference risks caused by additional openings.

[0031] In some implementations, refer to Figure 1 The isolation plate 30 is recessed upward at the central hole 31 to form a raised platform 32, thereby raising the central hole 31 and making its position higher than other areas of the isolation plate 30, further optimizing the overall waterproof effect. Specifically, the raised platform 32 is integrally formed by the upward recess of the isolation plate 30 itself, raising the height of the central hole 31, thus forming a water-blocking edge around the central hole 31. When liquid flows along the isolation plate 30 to the central hole 31 and attempts to seep in through the gap between the interface and the central hole 31, the recessed shape of the raised platform 32 can prevent the liquid from flowing into the central hole 31, causing it to lose its attachment and drip when it reaches the edge of the raised platform 32. This reduces the risk of liquid seeping through the gap in the central hole 31 and prevents liquid from adhering to the metal part of the information transmission interface that exits from the central hole 31 and causing corrosion, thus strengthening the waterproof barrier function of the isolation plate 30 in separating the upper and lower receiving cavities.

[0032] Furthermore, the height of the raised hole 31 allows the bottom surface of the information transmission interface to be further away from the wire displacement gauge 20. On the one hand, this provides more installation positions for the information transmission interface, allowing for the installation of a relatively long information transmission interface. On the other hand, when the device is placed close to the ground, the raised information transmission interface has a larger connection space relative to the ground, which can support the connection with external wiring.

[0033] In some implementations, refer to Figure 1The pull-wire displacement gauges 20 are arranged in a ring around the bottom of the housing 10, and are fitted against the inner wall of the housing 10. Specifically, multiple pull-wire displacement gauges 20 are arranged in a ring along the inner wall of the bottom of the housing 10. This arrangement serves two purposes: firstly, it keeps the information transmission interface, which passes through the central hole 31, away from the interface, providing sufficient connection space and preventing liquid from directly adhering to the connection point between the interface and the external wire; secondly, this arrangement helps guide the flow of liquid that seeps into the bottom of the housing 10. When rainwater or accumulated water seeps in, it flows downwards along the inner wall of the housing 10. The displacement gauges, with their main structures tightly fitted to the inner wall, reduce liquid accumulation at the bottom of the gauges, making it easier for the liquid to drain through the drainage channels on the bottom side wall of the housing 10. This prevents corrosion of mechanical parts caused by prolonged contact with water, extending the service life of the displacement gauges.

[0034] Furthermore, the circular layout allows the monitoring lines 40 of each pull-wire displacement gauge 20 to be led out in a more dispersed direction, which can effectively prevent multiple monitoring lines 40 from getting tangled together at the outlet of the housing 10. Each monitoring line 40 can be led out from the side wall of the housing 10 at the location of the corresponding displacement gauge, each pointing to a different slope monitoring point. The route is clear, which is convenient for wiring during on-site installation and also facilitates quick identification of the displacement gauge corresponding to each monitoring line 40 during later maintenance. This reduces the difficulty of maintenance in complex mining environments and ensures the stable operation of the monitoring device.

[0035] In some implementations, refer to Figure 2 The wire-type displacement gauge 20 is connected to a monitoring line 40. The end of the monitoring line 40 away from the wire-type displacement gauge 20 is set along an arc trajectory, thereby obtaining a relatively wide monitoring coverage range. This is beneficial for providing raw data from more dimensions and improving the speed of risk response. In terms of spatial coverage, the ring arrangement can adapt to monitoring objects of different sizes through an adjustable radius, from small and medium-sized slopes of tens of meters to large foundation pits of hundreds of meters. By simply adjusting the length of the wire or appropriately increasing the number of displacement gauges, it can achieve coverage without blind spots, avoiding the local blind spots of traditional linear arrangements. At the same time, it takes into account three-dimensional displacement monitoring in both horizontal tangential and radial directions, allowing limited equipment to cover a larger area. In terms of data dimensions, the ring arrangement can not only capture local displacement through independent data from each endpoint, but also integrate overall data based on the geometric correlation of the ring. If all endpoints displace in the same direction, it can be determined that the overall slippage of the monitored object can be determined; if only the displacement of local adjacent endpoints is abnormal, it can help locate concentrated deformation areas.

[0036] In some implementations, refer to Figure 3A monitoring line 40 is connected to the pull-wire displacement gauge 20. The monitoring line 40 is inclined to the ground, and the angle between the monitoring line 40 and the first direction axis is acute. The first direction is the length extension direction of the left and right sides of the upper surface of the housing 10 when the first direction and the monitoring line 40 are inclined to the ground. Specifically, the first direction is defined as the potential deformation direction of the slope, which is usually determined by geotechnical analysis. At this time, the placement of the housing 10 is adjusted so that the length extension direction of the left and right sides of the upper surface of the housing 10 is aligned with the potential main deformation direction, so that the first direction directly matches the core direction of slope risk. The monitoring line 40 is set at an acute angle to the first direction axis, which ensures that the main monitoring dimension of the monitoring line 40 is close to the main deformation direction, and can prioritize the capture of the most critical displacement changes of the slope, thereby ensuring that the displacement data in the main deformation direction accounts for the highest proportion. In subsequent data processing, there is no need for complex vector decomposition, only simple filtering is needed to extract the core risk data, thereby reducing the data processing process and lag. Mine slope monitoring requires high real-time performance. If the data needs to go through multiple steps of calculation before the risk can be determined, the best early warning opportunity may be missed. This design allows the displacement meter to directly output the displacement in the key direction, assisting the early warning system in responding quickly.

[0037] Furthermore, on steep slopes and slopes with well-developed gullies, horizontal layouts are prone to obstruction due to terrain, while vertical layouts are difficult to cover key monitoring points in the middle of the slope. However, when laid out along the slope direction, the wires can be flexibly laid from the stable benchmark point at the top of the slope to the monitoring points in the middle and at the bottom of the slope, conforming to the terrain contour to ensure the wires are straight, while avoiding obstacles such as protruding rocks and vegetation. Even on irregular slopes, effective monitoring of key points can be achieved.

[0038] In some implementations, refer to Figure 4 A monitoring line 40 is connected to the wire-type displacement gauge 20, and the angle between the monitoring line 40 and the axial direction of the second direction is acute. The second direction is the length extension direction of the upper and lower sides of the upper surface of the housing 10. Specifically, the second direction is set to accommodate possible lateral deformations of the slope, such as the outward horizontal extension of the slope top due to the collapse of the lower rock layer, or the inward contraction due to compression. The monitoring line 40 is set at an acute angle to the second direction, thereby prioritizing the capture of the main displacement components in the second direction. This angle design does not require the monitoring line 40 to be completely parallel to the second direction. The angle can be finely adjusted according to the actual distribution of monitoring points on the slope, so that the monitoring line 40 produces a more obvious stretching or contraction when lateral displacement occurs. The displacement gauge can more accurately convert this into an electrical signal. Combined with the monitoring data of the first direction, the actual deformation trajectory of the slope can be calculated through vector synthesis, providing a more comprehensive quantitative basis for stability assessment.

[0039] In some implementations, refer to Figure 1The internal components include a GPS module, an audible and visual alarm, a signal transceiver, a lithium battery, and a repeater. Specifically, the core function of the GPS module is to assign spatial coordinates to the monitoring data, thereby dividing the mine slope into multiple monitoring zones and ensuring that the displacement data collected by each set of wire displacement gauges 20 can correspond to the specific monitoring point on the slope.

[0040] The audible and visual alarm is used for real-time risk warning at the mine site, and its triggering mechanism is linked to the monitoring data of the pull-wire displacement gauge 20.

[0041] The transceiver is used to enable data interaction between the monitoring device and external equipment. Given that rare earth mines are often located in remote mountainous areas with weak public communication signals, it supports multi-mode communication adaptation. In open-pit mines or areas with good signal coverage, real-time monitoring data can be transmitted to a remote monitoring center via network for real-time data visualization. In deep mining areas, such as valleys or gullies where signals are weak, it can switch to a low-power wide-area network (LPWAN) mode, leveraging its strong anti-interference capabilities over long distances to ensure uninterrupted data transmission.

[0042] The lithium battery provides a stable power supply for all internal components, thus solving the problems of unstable temporary power supply and difficult wiring that often exist at rare earth mine sites.

[0043] Repeaters address the signal attenuation problem caused by the complex terrain of mines, serving to enhance signals and extend transmission.

[0044] In some implementations, refer to Figure 1 The side surface of the draw-wire displacement gauge 20 is connected to the lower surface of the isolation plate 30 via a gasket 50. The side surface of the draw-wire displacement gauge 20 is perpendicular to the ground, and the top surface of the draw-wire displacement gauge 20 does not contact the bottom surface of the isolation plate 30. Specifically, the side surface of the draw-wire displacement gauge 20 is connected to the lower surface of the isolation plate 30 via a gasket 50. This can be represented as the draw-wire displacement gauge 20 and the lower surface of the isolation plate 30 being connected by an L-shaped gasket 50. The purpose of this lateral connection is to prevent the top surface of the draw-wire displacement gauge 20 from contacting the bottom surface of the isolation plate 30, thereby creating a preset gap between the top surface of the draw-wire displacement gauge 20 and the isolation plate 30. This allows water to flow smoothly along the top surface of the displacement gauge. Combined with the design that the side surface of the displacement gauge is perpendicular to the ground, the water can quickly drain downwards along the vertical side surface, avoiding stagnation at the top of the displacement gauge.

[0045] In some implementations, refer to Figure 1The gasket 50 has a perforation, and the isolation plate 30 also has a corresponding perforation. The wire displacement gauge 20 is electrically connected to the internal components through the perforation, so that water that may be present in the lower cavity cannot penetrate upward through this gap, preventing water from entering the upper cavity along the outer wall of the line, ensuring that the electrical components of the internal components are not damp, and maintaining the stability of the electrical connection.

[0046] It should be noted that this application is not limited to the above-described embodiments. The above embodiments are merely examples, and any embodiments with the same structure and effect as the technical concept within the scope of this application are included in the technical scope of this application. Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
