In order to ensure the safety of the tailings dam, it is generally necessary to install a corresponding monitoring system to monitor the status of the tailings dam in real time. The Chinese invention patent with publication number CN114942041B discloses a tailings pond safety monitoring system and method. Through a dry beach detection device, an infiltration line detection device, a settlement detection device, a displacement detection device, a rainfall detection device and a water level detection device, the dry beach slope and dry beach length of the tailings dam, the seepage in the tailings dam, the settlement and displacement of the tailings dam, the rainfall in the tailings pond area and the water level information of the reservoir area can be automatically monitored in real time. When the monitoring information is abnormal, an alarm can be issued in time, which saves the trouble of manual regular inspections, and is not affected by weather. The monitoring data is accurate and reliable.

[0003] In the related technology, the existing tailings dam safety monitoring system generally conducts real-time monitoring of the dry beach slope and dry beach length of the tailings dam, the seepage in the tailings dam, the settlement and displacement of the tailings dam, the rainfall in the tailings pond area and the water level information in the reservoir area, but lacks the function of flood discharge monitoring. As a result, when the rainfall is too heavy and the flood discharge system fails, flood discharge cannot be carried out in time, which leads to various safety hazards such as rockfall and landslides in the reservoir area. In addition, when monitoring the tailings dam, there is a lack of the function of corresponding to the data of previous years, so that when hidden dangers occur, the staff cannot arrange response measures in time.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Embodiment 1:

[0039] See attached Figure 1 , a tailings dam safety monitoring system, comprising a deformation monitoring module for detecting deformation of the tailings dam, a density monitoring module for detecting density of the tailings dam, a precipitation monitoring module for detecting precipitation in the tailings pond area, a flood discharge monitoring module for detecting flood discharge of the tailings pond, a seepage monitoring module for detecting seepage of the tailings dam and the tailings pond, and a control processing center for acquiring 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, and for 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 to prevent landslides caused by heavy rainfall and unsatisfactory flood discharge situation, 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 inside the tailings dam;

[0042] The seepage monitoring module includes seepage pressure monitoring and seepage flow monitoring. The main methods for monitoring seepage pressure are piezometers, pressure tubes and pressure holes. The piezometers can be divided into four types according to the measurement principle: vibrating string type, inductive type, resistive type and piezoresistive type. The seepage flow measurement includes volumetric method, water measuring 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 displacement and vertical displacement of the tailings dam.

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

[0045] Horizontal displacement monitoring methods include sight line method, tension line method, laser alignment method, vertical and inverted vertical line method, precision wire method and forward intersection method, etc.

[0046] The main methods for vertical displacement monitoring include geometric leveling, hydrostatic leveling and vertical height transfer.

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

[0048] Through the setting of the data storage module, the monitoring data of previous years can be processed, which makes it convenient to compare the current monitoring data with the data of previous years through the data comparison module, and to issue an alarm notification through the alarm module, so that the staff can timely understand the current monitoring data and make corresponding protective response measures, saving time in finding response measures for tailings dams and solving the problem that the existing monitoring system still needs to spend time to arrange response measures after monitoring the tailings dam.

[0049] See attached Figures 2 to 8 A tailings dam safety monitoring device, the monitoring device comprises 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, and at least one horizontal detection component 5 with adjustable angle is arranged on the outer surface of the measuring rod 1;

[0050] By setting the anchor rod 2, the monitoring device is installed inside the tailings dam. By setting the control system 3 capable of wirelessly transmitting and receiving signals, the data monitored by the monitoring device can be transmitted and alarmed by wireless communication, so that the staff can know and take corresponding measures in time.

[0051] By setting the vertical detection component 4, the vertical displacement of the tailings dam can be monitored, and by setting the horizontal detection component 5, the horizontal displacement of the tailings dam can be detected, effectively combining the vertical displacement and horizontal displacement monitoring, having multiple monitoring functions, and further improving the functionality and practicality of the monitoring equipment;

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

[0053] A plurality of force plates 42 are fixedly connected to the outer surface of the vertical cylinder 41, and the force plates 42 can be used to detect the vertical downward displacement driving force of the tailings dam, so that the vertical cylinder 41 and the force plates 42 move synchronously following the vertical downward driving force of the tailings dam, and the first dynamometer 43 is used to detect the downward driving force, so as to understand the vertical displacement of the tailings dam;

[0054] The level detection assembly 5 includes an articulated block 51 connected to the outer surface of the measuring rod 1, one side of the articulated block 51 is rotatably connected to a monitoring tube 52 via a rotating shaft, and an angle sensor 53 for monitoring the angle of the rotating shaft is fixedly mounted on the articulated block 51;

[0055] By placing the monitoring tube 52 horizontally above or inside the tailings dam, the horizontal displacement of the tailings dam can be detected. By installing the monitoring tube 52 in a rotating hinged manner, the monitoring tube 52 can be driven at an angle according to the angle of the horizontal displacement of the tailings dam. The angle sensor 53 is used to detect the angle change of the monitoring tube 52, so as to further understand the horizontal displacement data of the tailings dam, so that subsequent staff can better manage the tailings dam.

[0056] See attached Figure 5 The inside of the measuring rod 1 is slidably connected with a threaded frame 44 and a sliding frame 45 from top to bottom in sequence, the first tensile gauge 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 tensile gauge 43 is fixedly connected to the sliding frame 45 through a connecting rod;

[0057] The sliding frame 45 is fixedly connected to the vertical cylinder 41, so that when the vertical cylinder 41 moves downward, the sliding frame 45 can be driven to move downward. The driving force of the vertical cylinder 41 moving downward can be detected by the first dynamometer 43, so as to obtain the vertical displacement data 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 inner surface of the threaded frame 44;

[0059] By driving the threaded rod 46 to rotate, the position of the threaded frame 44 can be adjusted up and down. By the up and down movement of the threaded frame 44, the first tension gauge 43 can be adjusted up and down, thereby facilitating the reset of the stretched part of the first tension gauge 43, and preventing the first tension gauge 43 from being in the unfolded state continuously, which not only makes it impossible to perform subsequent vertical displacement detection work, but also easily causes the problem of damage to the first tension gauge 43.

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

[0061] The threaded frame 44 is fixedly connected to the sliding frame 45 by a plurality of loose connecting ropes 47, which not only prevents the first tension gauge 43 from being damaged when the sliding frame 45 moves downward by a distance exceeding the detection stretching range of the first tension gauge 43, but also facilitates the sliding frame 45 to be driven by the connecting ropes 47 to rise and reset at the infiltration line position when the threaded frame 44 moves upward, and facilitates the first tension gauge 43 to be driven downward by the threaded frame 44 to reset the stretching part of the first tension gauge 43, thereby preventing the first tension gauge 43 from being in the expanded state continuously, which not only makes it impossible to perform subsequent vertical displacement detection work, but also easily causes the problem of damage to the first tension gauge 43.

[0062] See attached Figures 6 to 8 The outer surface of one end of the monitoring tube 52 is slidably connected to a sliding sleeve 54, and the outer surface of the sliding sleeve 54 is fixedly connected to a row of force blocks 55, the interior of the monitoring tube 52 is slidably connected to a transmission frame 56, and the transmission frame 56 is fixedly connected to the sliding sleeve 54, one end of the interior of the monitoring tube 52 is fixedly connected to a second tension meter 57, the tension end of the second tension meter 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 blocks 55 are fixedly connected to the outer surface of the sliding sleeve 54. The row of force blocks 55 can fully contact the tailings of the tailings dam. When the tailings dam is displaced horizontally, the displacement driving force can drive the row of force blocks 55 to move, and then the sliding sleeve 54 can drive the transmission frame 56 to move. The second dynamometer 57 can detect the displacement driving force of the transmission frame 56, and the control system 3 can be used to process the data, and an alarm can be performed through remote communication.

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

[0065] Embodiment 2: Based on embodiment 1, the difference is that;

[0066] See attached Figure 7 and Figure 8 At least three expansion frames 59 are provided on the outer surface of the other end of the monitoring tube 52, and an extendable protective gauze 510 is fixedly connected between the at least three expansion frames 59. One end of the at least three expansion frames 59 is hinged to the other end of the monitoring tube 52 through a hinge. At least three drive frames 511 are hinged to one side of the transmission frame 56, and one end of the at least three drive frames 511 is respectively hinged to the inner side surface of the corresponding expansion frames 59;

[0067] The three unfolding frames 59 are hingedly connected with the transmission frame 56 by using an inclined driving frame 511. When the transmission frame 56 is driven horizontally, it can drive the three driving frames 511 to unfold, and indirectly unfold the three unfolding frames 59. By unfolding the three unfolding frames 59, the tailings moving horizontally in the tailings dam can be limited to reduce the strength of its horizontal displacement. The three unfolding frames 59 are fixedly connected with an extendable protective gauze 510, which is convenient for the protective gauze 510 to be synchronously unfolded according to the three unfolding frames 59, further increasing the range of horizontal displacement protection, improving its horizontal displacement protection effect, and having good monitoring and protection functions;

[0068] The invention solves the problem that when monitoring the displacement of the tailings dam in the prior art, if the displacement force is large, the monitoring equipment will not only be damaged, but also cannot perform protective treatment on the displaced tailings dam in the first time.

[0069] Embodiment 3: Based on embodiment 1, the difference is that;

[0070] See attached Figure 3 and Figure 6 The outer surface of the measuring rod 1 is fixedly connected with a U-shaped block 6, and the hinge block 51 is slidably connected to the inside of the U-shaped block 6 in an up-and-down sliding manner. Two rows of locking holes 7 are opened inside the U-shaped block 6, and one group of locking holes 7 is fixed to the hinge block 51 adjusted up and down by a fastening bolt 8;

[0071] The hinge block 51 is installed inside the U-shaped block 6 by sliding up and down, so that when the monitoring equipment is installed, the installation position of the horizontal detection component 5 can be adjusted according to the actual slope conditions, so that it is convenient to install it above the tailings dam body or inside the tailings dam, thereby meeting the monitoring of the horizontal displacement of the surface of the tailings dam or the monitoring of the horizontal displacement inside the tailings dam, further improving its monitoring range, and the setting of the fastening bolts 8 is used to fix the horizontal detection component 5 after the up and down adjustment to ensure its stability during the subsequent monitoring process.

[0072] It should be noted that the term "comprises" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article, or device that includes a series of elements includes not only those elements, but also includes other elements that are not explicitly listed, or also includes elements inherent to such process, method, article, or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article, or device that includes the element.

[0073] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
