Description

Technical Field

[0001] This invention relates to the field of slope monitoring device technology, specifically to an online monitoring system for mine slopes. Background Technology

[0002] In open-pit mines, slope stability is often a prominent issue, especially in bedding slopes. Due to the complexity of rock strata and joints, slope instability is more likely to occur, leading to geological disasters such as landslides and debris flows. Every summer, excessive rainfall, especially heavy or continuous rainfall, causes rainwater to rapidly infiltrate the slope soil, leading to a rapid increase in soil moisture content. When the rainfall intensity exceeds the soil infiltration rate, the shallow slope soil quickly becomes saturated, forming surface runoff and eroding the slope surface. Simultaneously, rainwater infiltration into the slope interior alters the seepage field, increasing both dynamic and static water loads on the soil, thereby reducing its shear strength. This leads to a series of problems:

[0003] (1) Summer rainfall is heavy and poses a serious threat to the stability of open-pit mine slopes. Excessive rainwater will quickly seep into the slope soil, increasing the soil's moisture content and leading to slope instability.

[0004] (2) Due to the steep slopes of the company's mining and storage yards and the heavy snow accumulation in winter, personnel are prone to slipping and falling during inspections, which also poses unpredictable safety hazards to on-site workers. Utility Model Content

This description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this invention.

[0024] Example 1

[0025] An online monitoring system for mine slopes, such as Figure 1-3As shown, the system includes: a column 1, a motor 2, a coordinate positioning mechanism 3, a slope radar 4, a solar power generation mechanism, and a controller 8. The bottom of the column 1 is pre-embedded in the soil on the opposite side of the slope, and the location is selected according to the monitoring needs. The top of the column 1 is equipped with a motor 2, which drives the coordinate positioning mechanism 3 to rotate at a set angle. The output axis of the motor 2 extends upward and is fixedly connected to the coordinate positioning mechanism 3. The slope radar is installed on the coordinate positioning mechanism. By moving the slope radar through the coordinate positioning mechanism, the slope radar can collect slope deformation information at different positions. The slope radar 4 is connected to the controller 8 via a wire and is used to collect slope deformation information. The controller 8 is electrically connected to the motor 2 and the coordinate positioning mechanism 3 via a wire. The solar power generation mechanism is configured to supply power to the controller 8, the slope radar 4, the motor 2, and the coordinate positioning mechanism 3.

[0026] Existing slope radars are typically erected on the ground using tripods, making it inconvenient to adjust the height and position of the radar. This new type incorporates a coordinate positioning mechanism, allowing the selection of the most suitable monitoring location based on monitoring needs. The controller enables the slope radar to detect slope deformation at multiple fixed points. Due to the complex shape of slopes, the coordinate positioning mechanism significantly reduces the difficulty of slope radar detection and improves ease of use. Furthermore, because the coordinate positioning mechanism provides accurate coordinates, the reference position can be consistent for each monitoring session, allowing for data comparison.

[0027] Example 2

[0028] Based on Example 1, such as Figure 1 , 2 As shown, this embodiment is improved as follows:

[0029] The bottom end of the column 1 is provided with a pre-embedded cement seat (not shown in the figure), and the pre-embedded cement seat is located in the soil.

[0030] The solar power generation mechanism includes: several fan-shaped mounting plates 5 distributed around the outer periphery of the top of the column 1 along the axis; solar panels 19 are mounted on the upper surface of the mounting plates 5; a battery box (not shown in the figure) is provided on the surface of the column 1; a storage battery is provided in the battery box; and the solar panels 19 are configured to charge the storage battery.

[0031] An electric cylinder 9 is connected between the lower surface of the mounting plate 5 and the outer surface of the column 1. The two ends of the electric cylinder 9 are respectively hinged to the lower surface of the mounting plate 5 and the outer surface of the column 1. The outer edge of the top of the column 1 is coaxially fixedly connected to a fixing ring 6 through a connecting block 7. The inner end of the mounting plate 5 is hinged to the fixing ring 6. A photosensitive sensor (not shown in the figure) is provided on the outer surface of the mounting plate 5. The electric cylinder 9 and the photosensitive sensor are electrically connected to the controller 8.

[0032] In this embodiment, a mounting plate is provided on the outer perimeter of the column, and a solar panel is installed on the mounting plate. This maximizes the use of the column space to power the entire system, thus avoiding the problem of insufficient solar panel efficiency during cloudy or rainy weather. Simultaneously, the angle of the mounting plate is adjusted by a controller to orient the solar panel towards the optimal direction of sunlight, further improving power generation efficiency.

[0033] Example 3

[0034] Based on Example 2, such as Figure 1 , 2 As shown in Figure 3, this embodiment is improved as follows:

[0035] The coordinate positioning mechanism 3 includes a first rectangular frame 11, a second rectangular frame 15, a first drive motor 13, a second drive motor 17, a first lead screw 12, a second lead screw 16, a first movable seat 14, a second movable seat (not shown in the figure), and a mounting base 18. The bottom center of the first rectangular frame 11 is fixedly connected to the output shaft of the motor 2. The first lead screw 12 is arranged horizontally along the inner edge of the first rectangular frame 11. The two ends of the first lead screw 12 are respectively rotatably connected to the middle of the side of the first rectangular frame 11. The first drive motor 13 is arranged on the outer side of one side of the first rectangular frame 11. The output shaft of the first drive motor 13 is fixedly connected to the end of the first lead screw 12. The first movable seat 14 is screwed onto the first lead screw 12. A second rectangular frame 15 arranged longitudinally is fixedly connected to the outer surface of the base 14. A second lead screw 16 is arranged longitudinally inside the second rectangular frame 15. The two ends of the second lead screw 16 are rotatably connected to the upper and lower ends of the second rectangular frame 15, respectively. A second drive motor 17 is provided at the top of the second rectangular frame 15. The output shaft of the second drive motor 17 is fixedly connected to the top of the second lead screw 16. A second movable seat is screwed to the second lead screw 16. The two ends of the second movable seat are slidably connected to the inner surfaces of the two side walls of the second rectangular frame 15, respectively. A mounting base 18 is fixedly provided on the outer surface of the second movable seat. The slope radar 4 is fixedly installed on the outer surface of the mounting base 18. The first drive motor 13 and the second drive motor 17 are electrically connected to the controller 8 through wires, respectively.

[0036] The mechanism of coordinate positioning is as follows: a first drive motor moves a first moving base to control the position of the slope radar along the X-axis, and a second drive motor moves a second moving base to control the position of the slope radar along the Y-axis. Combined with the rotation angle of the motors, the working position of the slope radar can be accurately determined. The controller, based on a preset optimal acquisition position, drives the slope radar to different positions daily to collect slope deformation data, thus making it suitable for complex slope terrain.

[0037] Example 4

[0038] Based on Example 3, such as Figure 1 , 2 As shown in Figure 3, this embodiment is improved as follows:

[0039] The top of the column 1 is coaxially provided with an annular guide rail 20, and the bottom two sides of the first rectangular frame 11 are respectively slidably connected to the annular guide rail 20 by sliders to promote the stability of the first rectangular frame operation.

[0040] The first rectangular frame 11 has linear guide rails 21 arranged horizontally on its upper and lower front surfaces, and the rear surfaces of the upper and lower ends of the second rectangular frame 15 are slidably connected to the linear guide rails 21 to improve the stability of the second rectangular frame during operation.

[0041] Example 5

[0042] Based on Example 4, such as Figure 1 , 2 As shown in Figure 3, this embodiment is improved as follows:

[0043] The top of the first rectangular frame 11 is also equipped with a wind direction and speed sensor 10, which is electrically connected to the controller 8 via a wire. In windy weather, the controller can adjust the orientation of the mounting plate or the first rectangular frame to minimize the windward surface and provide shelter from the wind.

[0044] The controller 8 is connected to an alarm mechanism via wired or wireless means. The alarm mechanism includes an audible and visual alarm (not shown in the figure) located at the bottom edge of the slope. This alarm is used to sound an alarm when the slope becomes unstable, preventing staff from approaching. The alarm module is located on the host computer in the slope safety management office. This alarm module reports the slope instability information in detail so that managers can make quick decisions.

[0045] This new type of slope radar can be a commercially available portable slope radar or other radar products capable of performing the relevant functions. Alternatively, the slope radar can be replaced with other existing equipment capable of three-dimensional scanning of slope terrain. The distance between the slope radar and the slope is determined based on the radar product's detection range.
