Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mine slope monitoring, in particular to a mine slope stability monitoring device. BACKGROUND

[0002] Mine slope monitoring refers to a process of continuously or periodically monitoring, analyzing and warning the deformation, stress, environmental factors and other factors of the mine slope (including the step slope of the open-pit mine, the slope of the dump, etc.) through a series of technical means and equipment, so as to master the stability state of the slope, discover potential landslide, collapse and other geological disaster risks in advance, and provide scientific basis for mine safety production, engineering design and governance decision.

[0003] The Chinese invention patent with the publication number CN119251989A discloses a limestone mine slope monitoring and early warning device and system, which comprises: a transmission rod serving as a device carrying body for protecting the built-in device connection line; a GNSS cabinet installed on the left side of the transmission rod for monitoring slope data; a measuring bucket installed on the front side of the transmission rod for measuring rainfall; a warning light installed on the top of the GNSS cabinet for lighting the corresponding warning prompt light according to the calculation data; and a signal transceiver installed on the outer wall of the transmission rod for transmitting the signals obtained by the device over a long distance. Through real-time monitoring of the GNSS receiver, the inclination sensor and the crack sensor, combined with the strength reduction method and the finite element analysis, the system can comprehensively evaluate the real-time stability of the slope, further enhancing the quantitative evaluation ability of the real-time stability of the slope, especially under complex working conditions.

[0004] In addition, since the monitoring and early warning device in the comparative document does not mention the cooperative reinforcing structure of the protection mechanism and the supporting mechanism similar to the present application, the transmission rod as the carrying body may be installed only by simple insertion or foundation fixation, which is prone to tilt or displacement due to unstable foundation under complex working conditions such as loose soil and landslide risk of the mine, thereby causing the increase of monitoring data error or even equipment damage, and it is difficult to cope with the harsh environment of the mine slope. In addition, the device does not have the function design of real-time response and self-adaptive adjustment, and when the mine slope appears deformation, soil loosening and other conditions, the device is difficult to automatically enhance the fixation and maintain the posture stability, which may cause the core components such as the monitor and the signal transceiver to be separated from the effective working position, affecting the continuous collection and accurate transmission of the monitoring data, and unable to provide continuous and reliable data support for the slope stability evaluation.

[0041] The working process and principle of the above embodiment are as follows:

[0042] The working steps are as follows:

[0043] First, the operator controls the driving plate 2034 to slide up and down on the outer wall of the plug rod 201 through the external controller, so that the driving plate 2034 drives the triangular plate two 2035 to move downward synchronously, the triangular plate two 2035 drives the fixed plate two 204 to move downward synchronously, the fixed plate two 204 drives the connecting rod one 2063 to abut against the sliding groove 2062, the sliding groove 2062 drives the connecting plate one 2061 to move downward around the connecting rod two 2064 as the axis, the bottom end of the connecting plate one 2061 flips upward around the connecting rod two 2064 as the axis, the connecting plate one 2061 drives the connecting plate three 2067 connected with the bottom end to flip synchronously, the connecting plate three 2067 drives the connecting plate two 2065 to flip synchronously around the connecting rod three 2066 as the axis, the connecting plate three 2067 drives the plug plate 2068 to flip synchronously to the right upper side of the connecting rod three 2066, and then drives the supporting assembly 302 to flip synchronously, until the driving plate 2034 stops moving.

[0044] Subsequently, the operator inserts the plug 201 into the soil to fix the device. When the device is loosened in the mine soil or in harsh environments, the monitor 102 detects that the device is tilted or the fixing effect is reduced, and at this time, the monitor 102 transmits a detection signal to the external controller, and the external controller controls the driving plate 2034 to slide to the inside of the triangular plate 2032, so that the driving plate 2034 drives the triangular plate 2035 to move upward synchronously, so that the triangular plate 2035 drives the fixed plate 204 to move synchronously, so that the fixed plate 204 drives the connecting rod 2063 to slide in the sliding groove 2062 while rotating upward around the connecting rod 2064, so that the sliding groove 2062 drives the connecting plate 2061 to rotate synchronously under the action of the connecting rod 2063, so that the connecting plate 2061 drives the connecting plate 2067 connected at the bottom to move synchronously toward the side of the fixed plate 204 obliquely upward around the connecting rod 2064, so that the connecting plate 2067 drives the connecting plate 2065 connected thereto to move synchronously around the connecting rod 2066, so that the connecting plate 2067 drives the plug plate 2068 to move synchronously, and the plug plate 2068 drives the support assembly 302 to rotate clockwise and synchronously turn downward.

[0045] In the process of moving the support assembly 302, the external controller controls the strong magnetic plate 301 to repel the strong magnetic rod 3036, so that the strong magnetic rod 3036 moves downward, so that the top end of the support plate 3034 is rotated downward around the fixed block 3033, so that the support plate 3034 is rotated around the fixed block 3031 through the fixed block 3033 to the side away from the plug plate 2068, so that the support plate 3034 drives the support plate 3035 fixedly connected at the bottom to rotate upward, and in the process of moving the support plate 3034 downward, the support plate 3034 compresses the elastic telescopic rod 3038 through the fixed block 3037. When the strong magnetic plate 301 no longer magnetically repels the strong magnetic rod 3036, the elasticity of the elastic telescopic rod 3038 can reset the support plate 3034.

[0046] The device can significantly improve the fixing effect on the mine slope through the cooperation of the protection mechanism 200 and the supporting mechanism 300. When the device is tilted or the fixing effect is reduced, the driving assembly 202 can drive the insertion plate 2068 of the reinforcing assembly 205 to move to the deep soil or a more stable position, and reinforce the soil in the middle by surrounding and clamping the soil through the insertion plate 2068. At the same time, the support plate two 3035 of the supporting assembly 302 is expanded under the repulsive force of the strong magnetic plate 301 and the strong magnetic rod 3036 and the action of the elastic expansion rod 3038, so that the support plate one 3034 and the support plate two 3035 are inserted into the surrounding soil, increasing the contact area with the ground and enhancing the support strength. This double reinforcement structure enables the device to effectively cope with complex working conditions such as loose soil and landslide risks in mines, reducing monitoring data errors or equipment damage caused by unstable foundations.

[0047] The device has real-time response and self-adaptive adjustment capability. The external controller can drive the driving plate 2034, triangular plate two 2035 and other components to link up, so that the reinforcing assembly 205 and the supporting mechanism 300 dynamically adjust the fixing state according to the change of the slope stability. In harsh environments or in the early stage of slope deformation, the device can automatically enhance the fixation and maintain the stability of its posture, ensuring that the core components such as the monitor 102 and the antenna device 104 are always in an effective working position, and ensuring the continuous collection and accurate transmission of monitoring data, providing reliable data support for the stability evaluation of mine slope.
