Description

Technical Field

[0001] The present invention relates to the technical field of tailings dam safety monitoring, and specifically to a tailings dam safety monitoring system and monitoring equipment. Background Art

[0002] The tailings dam is one of the important facilities in the uranium hydrometallurgy plant, which has the functions of stacking tailings, leaching slag, clarifying liquid waste, and providing recycled water. To ensure the safety of the tailings dam, a corresponding monitoring system is generally installed to monitor the situation of the tailings dam in real time. The Chinese invention patent with the publication number CN114942041B discloses a tailings pond safety monitoring system and method, which realizes real-time automatic monitoring of the dry beach slope and dry beach length of the tailings dam, the seepage flow in the tailings dam, the settlement amount, displacement amount of the tailings dam, the rainfall in the tailings pond area, and the water level information of the reservoir area through a dry beach detection device, a phreatic line detection device, a settlement detection device, a displacement detection device, a rainfall detection device, and a water level detection device. When the monitoring information is abnormal, it can alarm in time, saving the trouble of manual regular inspection, and being unaffected by the weather, with accurate and reliable monitoring data.

[0003] In the related art, the existing tailings dam safety monitoring system generally monitors the dry beach slope and dry beach length of the tailings dam, the seepage flow in the tailings dam, the settlement amount, displacement amount of the tailings dam, the rainfall in the tailings pond area, and the water level information of the reservoir area in real time, lacking the function of flood discharge monitoring. As a result, when the rainfall is too large and the flood discharge system fails, the flood discharge work cannot be carried out in time, leading to various safety hazards such as rolling stones and landslides in the reservoir area. Moreover, when monitoring the tailings dam, it lacks the function of corresponding to the data of previous years. As a result, when hidden dangers occur, the staff cannot layout the corresponding countermeasures in time. Summary of the Invention

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Embodiment 1:

[0039] Referring to the attached Figure 1 , a tailings dam safety monitoring system includes a deformation monitoring module for detecting the deformation of the tailings dam, a density monitoring module for detecting the density of the tailings dam, a precipitation monitoring module for detecting the precipitation in the tailings reservoir area, a flood discharge monitoring module for detecting the flood discharge volume of the tailings reservoir, a seepage monitoring module for detecting the seepage of the tailings dam and the tailings reservoir, and a control processing center for acquiring the detection data of the deformation monitoring module, the density monitoring module, the precipitation monitoring module, the flood discharge monitoring module, and the seepage monitoring module, processing the data, and alarming through an alarm module;

[0040] Through the setting of the flood discharge monitoring module, the flood discharge situation of the tailings dam can be detected, preventing the problem of landslides caused by large precipitation and unsatisfactory flood discharge conditions, and further improving the scope of tailings dam safety monitoring;

[0041] The seepage monitoring module includes a seepage pressure monitoring unit for detecting the seepage pressure inside the tailings dam and a seepage flow monitoring unit for detecting the seepage flow volume inside the tailings dam;

[0042] The seepage monitoring module includes seepage pressure monitoring and seepage flow monitoring. The main methods for seepage pressure monitoring are piezometers, piezometric tubes, and piezometric holes. Among them, piezometers can be further divided into four types according to the measurement principle: vibrating wire type, inductive type, resistive type, and piezoresistive type; the measurement methods for seepage flow include volumetric method, weir method, flow velocity measurement method, and remote observation method.

[0043] The deformation monitoring module includes a horizontal displacement monitoring unit for detecting the horizontal displacement of the tailings dam and a vertical displacement monitoring unit for detecting the vertical displacement of the tailings dam. The deformation monitoring module also includes a three-dimensional displacement monitoring unit for synchronously detecting the horizontal and vertical displacements of the tailings dam;

[0044] By setting up the deformation monitoring module, not only can the vertical and horizontal displacements of the tailings dam be separately monitored to improve the monitoring effect, but also the vertical and horizontal displacements of the tailings dam can be synchronously monitored to improve the monitoring efficiency of the detection system;

[0045] The methods for horizontal displacement monitoring include sighting line method, tension wire method, laser collimation method, forward and reverse plumb line method, precise traverse method, and forward intersection method, etc.;

[0046] The main methods for vertical displacement monitoring are geometric leveling method, hydrostatic leveling method, and vertical height transfer method. The main methods for three-dimensional displacement monitoring of the dam are polar coordinate method, distance intersection method, three-dimensional laser scanning technology, GPS observation method, close-range photogrammetry method, aperture radar interferometry technology INSA, etc.

[0047] The tailings dam safety monitoring system also includes a data storage module for storing the data processed and analyzed by the control and processing center, and a data comparison module for comparing the data processed and analyzed by the control and processing center with the historical data in the data storage module and alarming the comparison data through the alarm module;

[0048] By setting up the data storage module, the monitoring data of previous years can be processed, which is convenient for comparing the currently monitored data with the previous years' data through the data comparison module, and alarming through the alarm module to inform the staff in time about the situation of the currently monitored data, enabling them to take corresponding protective countermeasures, saving the time for finding countermeasures for the tailings dam, and solving the problem that the existing monitoring system still needs to spend time on layout of countermeasures after monitoring the tailings dam.

[0049] Refer to the appendix Figures 2 to 8 A tailings dam safety monitoring device, the monitoring device includes a hollow measuring rod 1 and a fastening anchor rod 2 fixed to the bottom end of the measuring rod 1. A control system 3 capable of wirelessly transmitting and receiving signals is installed at the top end of the measuring rod 1. A vertical detection component 4 is arranged at the bottom end of the measuring rod 1. At least one horizontally adjustable detection component 5 is arranged on the outer surface of the measuring rod 1;

[0050] By setting the fastening bolt 2, the monitoring device is installed inside the tailings dam. Through the setting of the control system 3 that can wirelessly transmit and receive signals, the data monitored by the monitoring device can be transmitted and alarmed in a wireless communication manner, facilitating the staff to know in time and take corresponding measures;

[0051] By setting the vertical detection component 4, the vertical displacement of the tailings dam can be monitored. By setting the horizontal detection component 5, the horizontal displacement of the tailings dam can be detected. The vertical displacement and horizontal displacement monitoring are effectively linked and combined, with multi-faceted monitoring functions, further improving the functionality and practicality of the monitoring device;

[0052] The vertical detection component 4 includes a vertical cylinder 41 slidably connected to the outer surface of the measuring rod 1, and a force-bearing plate 42 is fixedly connected to the outer surface of the vertical cylinder 41. A first tensiometer 43 for detecting the driving force of the vertically downward moving vertical cylinder 41 is arranged inside the measuring rod 1;

[0053] By fixedly connecting a plurality of force-bearing plates 42 to the outer surface of the vertical cylinder 41, the driving force of the vertically downward displacement of the tailings dam can be detected through the force-bearing plates 42, so that the vertical cylinder 41 and the force-bearing plates 42 move synchronously following the vertically downward driving force of the tailings dam. Cooperating with the first tensiometer 43 to detect the driving force of the downward movement, the vertical displacement situation of the tailings dam can be understood;

[0054] The horizontal detection component 5 includes a hinge block 51 connected to the outer surface of the measuring rod 1. A monitoring tube 52 is rotatably connected to one side of the hinge block 51 through a rotating shaft, and an angle sensor 53 for monitoring the angle of the rotating shaft is fixedly installed on the hinge block 51;

[0055] By placing the monitoring tube 52 above or inside the tailings dam, the horizontal displacement of the tailings dam can be detected. By installing the monitoring tube 52 in a rotatable hinge manner, it is convenient for the monitoring tube 52 to drive the angle according to the angle of the horizontal displacement of the tailings dam. Then, cooperating with the angle sensor 53 to detect the angle change of the monitoring tube 52, the horizontal displacement data of the tailings dam can be further understood, facilitating the subsequent management work of the staff for the tailings dam.

[0056] Refer to the appendix Figure 5 Inside the measuring rod 1, a threaded frame 44 and a sliding frame 45 are slidably connected in sequence from top to bottom. The first tensiometer 43 is fixed to the bottom of the threaded frame 44, and the sliding frame 45 is fixedly connected to the vertical cylinder 41. And the tension end of the first tensiometer 43 is fixedly connected to the sliding frame 45 through a connecting rod;

[0057] The vertical cylinder 41 is fixedly connected to the sliding frame 45. When the vertical cylinder 41 moves downward, it can drive the sliding frame 45 to move downward. The driving force of the downward movement of the vertical cylinder 41 can be detected by the first tensiometer 43, so as to obtain the data of the vertical displacement of the tailings dam;

[0058] The bottom end of the measuring rod 1 is rotatably connected to a threaded rod 46, and the outer surface of the bottom end of the threaded rod 46 is threadedly connected to the inside of the threaded frame 44;

[0059] By rotating and driving the threaded rod 46, the position of the threaded frame 44 can be adjusted up and down. Through the up and down movement of the threaded frame 44, the first tensiometer 43 can be adjusted up and down, which is convenient for the reset of the stretching part of the first tensiometer 43, preventing the first tensiometer 43 from remaining in the extended state all the time. This will not only make it impossible to carry out subsequent vertical displacement detection work, but also easily cause damage to the first tensiometer 43;

[0060] A number of loose connecting ropes 47 are fixedly connected between the threaded frame 44 and the sliding frame 45;

[0061] By fixedly connecting the threaded frame 44 to the sliding frame 45 with a number of loose connecting ropes 47, it not only avoids damage to the first tensiometer 43 when the downward displacement distance of the sliding frame 45 exceeds the detection and stretching range of the first tensiometer 43, but also is convenient for the sliding frame 45 to rise and reset at the position of the phreatic line driven by the connecting rope 47 when the threaded frame 44 moves upward, and is convenient for driving the first tensiometer 43 to move downward when the threaded frame 44 moves downward, forming the reset of the stretching part of the first tensiometer 43, preventing the first tensiometer 43 from remaining in the extended state all the time. This will not only make it impossible to carry out subsequent vertical displacement detection work, but also easily cause damage to the first tensiometer 43;

[0062] Refer to the appendix Figures 6 to 8 One end of the monitoring pipe 52 is slidably connected to the outer surface of a sliding sleeve 54, and a row of force-receiving blocks 55 are fixedly connected to the outer surface of the sliding sleeve 54. A transmission frame 56 is slidably connected to the inside of the monitoring pipe 52, and the transmission frame 56 is fixedly connected to the sliding sleeve 54. One end inside the monitoring pipe 52 is fixedly connected to a second tensiometer 57. The pulling end of the second tensiometer 57 is fixedly connected to a safety rope 58, and one end of the safety rope 58 is fixedly connected to the transmission frame 56;

[0063] A row of force - receiving blocks 55 is fixedly connected to the outer surface of the sliding sleeve 54. Through the row of force - receiving blocks 55, full contact with the tailings of the tailings dam can be achieved. When the tailings dam undergoes horizontal displacement, the displacement driving force can drive the row of force - receiving blocks 55 to displace. Furthermore, the driving frame 56 can be driven to displace through the sliding sleeve 54. The displacement driving force of the driving frame 56 can be detected through the second tensiometer 57. The data is processed in cooperation with the control system 3, and alarm work is carried out through remote communication means;

[0064] The tension end of the second tensiometer 57 is fixedly connected to the driving frame 56 by a safety rope 58. So that when the horizontal displacement driving force exceeds the detection range of the second tensiometer 57, the safety rope 58 will break. This not only effectively protects the second tensiometer 57 and prevents damage to the second tensiometer 57 caused by excessive tension, but also can timely deploy the protective components of the horizontal detection assembly 5 to form the displacement protection work of the tailings dam.

[0065] Embodiment 2: The difference from Embodiment 1 is as follows;

[0066] Refer to the appendix Figure 7 and Figure 8 On the outer surface of the other end of the monitoring pipe 52, at least three deployment frames 59 are provided. A stretchable protective screen 510 is fixedly connected between at least three deployment frames 59. One end of at least three deployment frames 59 is respectively hinged to the other end of the monitoring pipe 52 through a hinge. On one side of the driving frame 56, at least three driving frames 511 are hinged, and one end of at least three driving frames 511 is respectively hinged to the inner side surface of the corresponding deployment frame 59;

[0067] Through the three deployment frames 59, the inclined driving frames 511 are hinged to the driving frame 56. When the driving frame 56 is driven horizontally, it can drive the three driving frames 511 to deploy, indirectly causing the three deployment frames 59 to deploy. Through the deployment of the three deployment frames 59, the tailings moving horizontally in the tailings dam can be limited, reducing the horizontal displacement force. Since a stretchable protective screen 510 is fixedly connected between the three deployment frames 59, it is convenient for the protective screen 510 to be deployed synchronously with the three deployment frames 59, further increasing the range of horizontal displacement protection and improving the horizontal displacement protection effect, having a good monitoring and protection function;

[0068] It solves the problem that in the prior art, when the monitoring equipment monitors the displacement of the tailings dam, if the displacement force is large, the monitoring equipment will not only be damaged, but also cannot protect the displaced tailings dam in the first place.

[0069] Embodiment 3: The difference from Embodiment 1 is as follows;

[0070] Refer to the appendix Figure 3 andFigure 6 On the outer surface of the measuring rod 1, a U-shaped block 6 is fixedly connected. The hinge block 51 is slidably connected inside the U-shaped block 6 in a vertical sliding manner. Two rows of locking holes 7 are formed inside the U-shaped block 6. One set of the locking holes 7 is fixed to the vertically adjusted hinge block 51 through a fastening bolt 8.

[0071] By installing the hinge block 51 inside the U-shaped block 6 in a vertical sliding manner, when the monitoring device is installed, the installation position of the horizontal detection assembly 5 can be adjusted according to the actual slope conditions, so as to facilitate the installation above the tailings dam or inside the tailings dam, and further meet the monitoring of the horizontal displacement on the surface of the tailings dam or the horizontal displacement inside the tailings dam, further improving its monitoring range. Through the setting of the fastening bolt 8, it is used to fix the horizontally adjusted detection assembly 5 to ensure its stability during subsequent monitoring.

[0072] It should be noted that the term "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not explicitly listed, or further includes elements inherent to such a process, method, article or device. Without further limitation, an element defined by the statement "comprising one..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the said element.

[0073] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
