Description

Technical Field

[0001] The utility model relates to the technical field of slope deformation monitoring equipment, in particular to an open-pit mine slope deformation monitoring equipment and a system. Background Art

[0002] Open-pit mining requires digging mining pits on the mine, which will form slopes around the mining pits. Once the slopes are deformed, collapse accidents may occur, causing the mining pits to be filled up, posing a life-threatening hazard to personnel in the mining pits. Therefore, slope protection and monitoring are very important tasks in the open-pit mining process.

[0003] In the prior art, the slope protection work of open-pit mines is usually carried out by laying protective nets on the slopes, while the deformation monitoring of the slopes is carried out by arranging personnel to patrol around the mine slopes. Once deformation of the slope is found, an alarm and disposal are immediately issued.

[0004] However, when monitoring slope deformation manually, the accuracy and patrol distance of the human eye are limited. Some deformations of small magnitude at a long distance are difficult to detect. By the time the deformation accumulates to a large magnitude, disaster may be unavoidable. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] See also Figures 1 to 4 The utility model provides a technical solution: an open-pit mine slope deformation monitoring device, comprising: a monitor 8, a slope 1 is arranged at the bottom end of the monitor 8, a rivet 3 is inserted and fixed on the surface of the slope 1, a protective net 2 is fixed on the surface of the rivet 3, and the protective net 2 covers the slope surface of the slope 1, a resistor mounting hole 7 is opened on the surface of the monitor 8, one end of a resistor 6 is movably inserted in the resistor mounting hole 7, a rope 4 is fixed to the other end of the resistor 6, and the other end of the rope 4 is fixed to the surface of the protective net 2, and an alarm 9 is arranged on the top of the monitor 8.

[0024] In actual use, the slope surface of the slope 1 is covered with a protective net 2, and a monitor 8 is fixed to the top of the slope 1. When the slope surface of the slope 1 is deformed, the deformation of the slope surface of the slope 1 will inevitably lead to the deformation of the protective net 2. The bottom end of the protective net 2 is fixed to the slope 1 by a rivet 3, and the top of the protective net 2 is fixed to the resistor 6 by a rope 4, and the resistor 6 is movably inserted in the resistor mounting hole 7. Therefore, the deformation of the protective net 2 will inevitably cause the distance that the resistor 6 extends from the resistor mounting hole 7 to change. When the distance that the resistor 6 extends from the resistor mounting hole 7 changes, it will be sensed by the controller 17 with a voltmeter set in the monitor 8, and then the controller 17 with a voltmeter will energize the alarm 9, so that the alarm 9 will sound an alarm through sound and light signals, thereby automating the deformation monitoring of the slope 1, reducing the application of manpower, and increasing the accuracy of monitoring.

[0025] Embodiment 2

[0026] On the basis of the first embodiment, in order to enable the controller 17 with a voltmeter to sense that the distance of the resistor mounting hole 7 extending from the resistor mounting hole 7 has changed, a traction spring 13 is fixed to one end of the monitor 8 extending into the resistor mounting hole 7, and the other end of the traction spring 13 is fixed to the inner wall of the resistor mounting hole 7. A connecting rod mounting groove 18 is provided on the inner wall of the resistor mounting hole 7, and a connecting rod 14 is slidably connected in the connecting rod mounting groove 18. One end of the connecting rod 14 is against the surface of the resistor 6, and the other end of the connecting rod 14 is fixed to a push spring 15 The other end of the push spring 15 is fixed on the inner wall of the connecting rod mounting groove 18. A controller mounting groove 10 is opened inside the monitor 8. A power supply 11 and a controller 17 with a voltmeter are arranged in the controller mounting groove 10. The positive pole of the power supply 11 is connected to the positive pole wire 12. The other end of the positive pole wire 12 is connected to the surface of the resistor 6. A negative pole wire 16 is connected to the surface of the connecting rod 14. The other end of the negative pole wire 16 is connected to the surface of the controller 17 with a voltmeter. The negative pole of the power supply 11 is connected to the surface of the controller 17 with a voltmeter.

[0027] In the initial state, the resistor 6 is in a force balance state under the tension of the traction spring 13 and the tension of the rope 4. At this time, the current enters the resistor 6 from the positive pole of the power supply 11 through the positive wire 12, and is connected to the connecting rod 14 through the resistor 6. Then, it flows into the controller 17 with a voltmeter through the negative wire 16 and then flows back to the negative pole of the power supply 11. The voltmeter in the controller 17 with a voltmeter can measure the voltage in the circuit. When the tension of the rope 4 on the resistor 6 increases or decreases, it will inevitably cause the part of the resistor 6 connected to the circuit to change, and then cause the resistance value of the resistor 6 to change. According to the physical law of series voltage division, the voltage measured by the controller 17 with a voltmeter in the controller mounting slot 10 changes, so that the controller 17 with a voltmeter can sense that the distance that the resistor 6 extends from the resistor mounting hole 7 has changed.

[0028] Embodiment 3

[0029] On the basis of the second embodiment, in order to make the connecting rod 14 abut against the surface of the resistor 6 , a push spring 15 is fixed to the other end of the connecting rod 14 , and the other end of the push spring 15 is fixed to the inner wall of the connecting rod installation groove 18 .

[0030] The push spring 15, which is compressed by the inner wall of the connecting rod installation groove 18 and the connecting rod 14, generates a thrust on the connecting rod 14 under its own elastic action, so that the connecting rod 14 is pressed against the surface of the resistor 6, ensuring that the resistor 6 is always connected to the circuit.

[0031] Embodiment 4

[0032] On the basis of the third embodiment, in order to realize the power-on control of the alarm 9, an alarm cable 5 is provided between the alarm 9 and the controller 17 with a voltmeter.

[0033] When the voltage measured by the voltmeter of the controller 17 with a voltmeter changes significantly, the controller 17 with a voltmeter energizes the alarm cable 5, so that the alarm 9 is connected in parallel to the circuit through the alarm cable 5, thereby energizing the alarm 9.

[0034] In actual use, the slope surface of the slope 1 is covered with a protective net 2, and a monitor 8 is fixed to the top of the slope 1. When the slope surface of the slope 1 is deformed, the deformation of the slope surface of the slope 1 will inevitably lead to the deformation of the protective net 2. The bottom end of the protective net 2 is fixed to the slope 1 by a rivet 3, and the top end of the protective net 2 is fixed to the resistor 6 by a rope 4. The resistor 6 is movably inserted in the resistor installation hole 7. Therefore, the deformation of the protective net 2 will inevitably cause the distance that the resistor 6 extends out of the resistor installation hole 7 to change. When the distance of the resistor 6 extending out of the resistor installation hole 7 changes, When it changes, it will be sensed by the controller 17 with a voltmeter set in the monitor 8, and then the controller 17 with a voltmeter will energize the alarm 9, so that the alarm 9 will warn through sound and light signals, thereby automating the deformation monitoring of the slope 1, reducing the use of manpower, and increasing the accuracy of monitoring; in the initial state, the resistor 6 is in a force balance state under the tension of the traction spring 13 and the tension of the rope 4. At this time, the current enters the resistor 6 from the positive electrode of the power supply 11 through the positive wire 12, and then connects to the connecting rod 14 through the resistor 6. The current flows into the controller 17 with a voltmeter through the negative conductor 16 and then flows back to the negative pole of the power source 11. The voltmeter in the controller 17 with a voltmeter can measure the voltage in the circuit. When the tension of the rope 4 on the resistor 6 increases or decreases, it will inevitably cause the part of the resistor 6 connected to the circuit to change, and then cause the resistance value of the resistor 6 to change. According to the physical law of series voltage division, the voltage measured by the controller 17 with a voltmeter in the controller installation slot 10 changes, which can make the controller 17 with a voltmeter sense that the resistor 6 has changed from the resistor installation slot to the resistor installation slot. The extended distance in the mounting hole 7 changes; the push spring 15, which is compressed by the inner wall of the connecting rod mounting groove 18 and the connecting rod 14, generates a thrust on the connecting rod 14 under the action of its own elasticity, so that the connecting rod 14 is pressed against the surface of the resistor 6, ensuring that the resistor 6 is always connected to the circuit; when the voltage measured by the voltmeter of the controller 17 with a voltmeter changes significantly, the controller 17 with a voltmeter energizes the alarm cable 5, so that the alarm 9 is connected in parallel to the circuit through the alarm cable 5, thereby energizing the alarm 9.
