Description

Technical Field

[0001] The utility model belongs to the technical field of geological disaster monitoring and early warning, and in particular relates to a monitoring and early warning device for preventing and controlling broken and loose mining rock slopes and dangerous rock masses. Background Art

[0002] Dangerous rock mass primarily refers to potential collapse masses. Although they haven't collapsed yet, they possess the necessary conditions for collapse and have already shown signs of collapse, indicating a possible collapse in the near future. Dangerous rock mass is a major geological disaster in mountainous areas, causing significant harm to residents, transportation, water conservancy, electricity, and construction within the affected area. The same applies to fragmented and loosened mining rock slopes.

[0003] A search revealed an existing patent (publication number: CN216287022U) that discloses an early warning assembly and dangerous rock warning device. The early warning assembly includes a switch base, a retaining spring, a fixing post, and an alarm. The switch base is provided with a switch fixing end and a switch contact end. The switch contact end comprises a metal body that contacts and conducts with the switch fixing end. The retaining spring is connected between the switch base and the switch contact end, and the fixing post is connected to the switch contact end via an insulating pull cord. The alarm is designed to emit an alarm signal when the metal body contacts and conducts with the switch fixing end. This dangerous rock warning device includes the aforementioned early warning assembly and a power supply assembly. The power supply assembly, alarm, switch fixing end, and switch contact end form a series circuit. Based on the principle of a single-pole, single-throw switch, it monitors the object being measured (dangerous rock) in real time. Once conduction occurs, an alarm signal is emitted. This not only provides timely and accurate early warnings, but also features a relatively simple monitoring method that is easier to implement.

[0004] However, there are still some shortcomings in the above structure. The warning component and dangerous rock warning device use the principle of single-pole single-throw switch to connect the fixing bolt and the switch handle with a rope. When the switch handle triggers the alarm, the dangerous rock body is displaced too far or even falls off, and its ability to monitor the tiny displacement data of the dangerous rock body is insufficient.

[0005] Therefore, it is necessary to provide a new monitoring and early warning device for preventing and controlling broken and loose mine rock slopes and dangerous rock masses to solve the above technical problems. Utility Model Content

[0006] The technical problem solved by the utility model is to provide a monitoring and early warning device for preventing and controlling broken and loose mining rock slopes and dangerous rock masses, which can monitor tiny displacement data of dangerous rock masses.

[0007] In order to solve the above technical problems, the present invention provides a monitoring and early warning device for preventing and controlling the fractured and loosened rock slopes and dangerous rock masses in mines, comprising: a protective box, a mounting plate and an insulating pull rope, wherein a detection mechanism is provided in the protective box and an adjustment component is provided on the mounting plate;

[0008] The detection mechanism includes a rotating shaft, which is rotatably mounted on the inner wall of the protective box. The insulating pull rope is wound around the rotating shaft, and a gear ring is fixedly sleeved on the rotating shaft. A rotational displacement sensor is fixedly mounted on the inner wall of the protective box. A circle counting gear is fixedly sleeved on the detection shaft of the rotational displacement sensor, and the circle counting gear is meshed with the gear ring. The other end of the insulating pull rope is fixedly connected to a fixed pile. An alarm is provided on one side of the protective box, and a signal transmission box is installed on the alarm.

[0009] As a further solution of the present invention, the adjusting assembly includes a threaded column, the bottom surface of the threaded column is fixedly connected to the top surface of the mounting plate, an adjusting nut is threadedly connected to the threaded column, a lifting tube is rotatably mounted on the top of the adjusting nut, the top surface of the lifting tube is fixedly connected to a fixed platform, a pulley is rotatably mounted on the fixed platform, a retaining ring is fixedly connected to the top surface of the adjusting nut, and a ring groove is provided on the bottom surface of the lifting tube.

[0010] As a further solution of the present invention, two limiting columns are slidably connected in the lifting tube, and the bottom surfaces of the limiting columns are fixedly connected to the bottom surface of the mounting plate.

[0011] As a further solution of the present invention, a hot-melt shrink tube is sleeved on the lifting tube, a pulley platform is fixedly installed on one side surface of the protective box, four bolts are threaded on the protective box, and the protective box is fixedly connected to the mounting plate through the four bolts.

[0012] As a further solution of the present invention, the fixed sleeve of the portion of the insulating pull rope wound around the rotating shaft is provided with a spiral plastic tube, and one end of the insulating pull rope is fixedly connected to the outer surface of the rotating shaft.

[0013] As a further solution of the present invention, four conical piles are fixedly connected to the bottom surface of the mounting plate, and the outer surface of the conical piles is provided with a stable rock mass, and a dangerous rock mass is provided on the stable rock mass.

[0014] Compared with related technologies, the monitoring and early warning device for preventing and controlling broken and loose mining rock slopes and dangerous rock masses provided by the present invention has the following beneficial effects:

[0015] 1. The present invention uses a detection mechanism to detect the rotational displacement data of the ring counter gear through a rotational displacement sensor, thereby obtaining the displacement data of the dangerous rock mass. The displacement data of the dangerous rock mass can be amplified by the size ratio of the gear ring to the ring counter gear, making it easier to observe the slight displacement of the dangerous rock mass, which is beneficial for monitoring and early warning of the dangerous rock mass. At the same time, the height position of the pulley can be adjusted by setting the adjustment component, reducing the difficulty of installing the mounting plate, so that the device can be installed on a slope or rock mass.

[0016] 2. The utility model adopts the setting of the heat-melt shrink tube. After the adjustment component is installed, the heat-melt shrink tube is cut and put on the lifting tube. It is heated to shrink and tighten it around the exposed part of the lifting tube and the threaded column to protect it and facilitate reuse. At the same time, the setting of the spiral plastic tube can tighten the insulating rope to improve the accuracy of the detection data. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] like Figure 4 As shown, the adjustment assembly includes a threaded column 11, the bottom surface of the threaded column 11 is fixedly connected to the top surface of the mounting plate 2, an adjusting nut 12 is threadedly connected to the threaded column 11, a lifting tube 13 is rotatably mounted on the top of the adjusting nut 12, the top surface of the lifting tube 13 is fixedly connected to a fixing platform 14, a pulley 15 is rotatably mounted on the fixing platform 14, a retaining ring 16 is fixedly connected to the top surface of the adjusting nut 12, and a ring groove 17 is formed on the bottom surface of the lifting tube 13;

[0026] By adjusting the setting of the assembly, the height position of the pulley 15 can be adjusted, thereby adjusting the angle of the insulating pull rope 3, thereby facilitating the installation of the fixing pile 8.

[0027] like Figure 4 As shown, two limiting columns 18 are slidably connected in the lifting tube 13, and the bottom surface of the limiting columns 18 is fixedly connected to the bottom surface of the mounting plate 2;

[0028] By providing the two limiting columns 18 , the lifting tube 13 can be limited when the adjusting nut 12 rotates to drive the lifting tube 13 to move up or down.

[0029] like Figure 2 As shown, a heat-melt shrink tube 19 is sleeved on the lifting tube 13 , a pulley platform 20 is fixedly installed on one side surface of the protection box 1 , four bolts 21 are threadedly connected to the protection box 1 , and the protection box 1 is fixedly connected to the mounting plate 2 via the four bolts 21 .

[0030] By setting the heat-melt shrink tube 19, after the adjustment component is installed, the heat-melt shrink tube 19 is cut and put on the lifting tube 13, and then heated to shrink and tighten it around the exposed part of the lifting tube 13 and the threaded column 11 to protect it and facilitate reuse.

[0031] like Figure 3 As shown, the portion of the insulating rope 3 wound around the rotating shaft 4 is fixed with a spiral plastic tube, and one end of the insulating rope 3 is fixedly connected to the outer surface of the rotating shaft 4;

[0032] By providing the spiral plastic tube, the insulating rope 3 can be tightened, thereby improving the accuracy of the detection data.

[0033] like Figure 1 As shown, four conical piles 22 are fixedly connected to the bottom surface of the mounting plate 2, and a stable rock mass 23 is provided on the outer surface of the conical piles 22, and a dangerous rock mass 24 is provided on the stable rock mass 23;

[0034] By providing the tapered piles 22 , the mounting plate 2 can be driven into the stable rock mass 23 for fixation, thereby improving the stability of the mounting plate 2 .

[0035] The working principle of the monitoring and early warning device for preventing and controlling the fractured and loosened rock slopes and dangerous rock masses provided by the utility model is as follows:

[0036] Step 1: When in use, first select a suitable installation position according to the position of the dangerous rock mass 24, then drive four tapered piles 22 and fixed piles 8 into the stable rock mass 23 and the dangerous rock mass 24 respectively for fixation, then fix the protective box 1 on the mounting plate 2 by four bolts 21, then pass the insulating pull rope 3 from above the pulley platform 20, and then pass the insulating pull rope 3 from below the pulley 15, and then fix the other end of the insulating pull rope 3 to the fixed pile 8, and cut off the excess insulating pull rope 3 so that the insulating pull rope 3 remains straight;

[0037] Step 2: When the dangerous rock mass 24 deflects, the fixed pile 8 is driven to displace, thereby lengthening the insulating rope 3 and driving the rotating shaft 4 to start rotating. The rotating shaft 4 drives the gear ring 5 to rotate, thereby driving the circle counting gear 7 to rotate. Then, the rotation displacement sensor 6 detects the rotation displacement data of the circle counting gear 7, thereby obtaining the deflection data of the dangerous rock mass 24. The deflection data of the dangerous rock mass 24 can be amplified by the size ratio of the gear ring 5 to the circle counting gear 7, making it easier to observe the slight deflection of the dangerous rock mass 24. Then, the signal transmission box 10 transmits the deflection data of the dangerous rock mass 24 to the remote monitoring end. When unqualified data is detected, the alarm 9 is turned on to issue a warning alarm to the surrounding area.

[0038] The third step: When the installation position of the tapered pile 22 is difficult to select, the adjusting nut 12 is rotated to lift and lower the adjusting nut 12 on the threaded column 11, thereby driving the lifting tube 13 to lift and lower, thereby adjusting the pull-out position of the insulating pull rope 3, and the pulley 15 can be used to adjust the pull-out angle of the insulating pull rope 3, reducing the installation difficulty of the mounting plate 2, so that the device can be installed on a slope or rock mass.
