Description

Technical Field

[0001] This utility model relates to the field of slope monitoring technology, specifically to an online monitoring device for non-coal mine slopes with multi-terminal data acquisition. Background Technology

[0002] Online slope monitoring refers to the real-time monitoring and analysis of slope stability through various sensors and monitoring technologies in order to prevent geological disasters such as landslides.

[0003] To overcome the aforementioned shortcomings, a Chinese patent (publication number: CN219589714U) discloses an online monitoring system for mine slope stability. This system includes a base, a connecting seat located on top of the base, and an annular seat located on top of the base. The annular seat is located outside the connecting seat, and a support assembly is provided on the outer side of the annular seat. When the base needs to be fixed, the bottom ends of multiple support rods are inserted into the ground. Since the four support rods are located around the base, the base can be supported in four directions, preventing it from shifting in one direction and maintaining stability. This replaces the effect of connecting the base to the ground with concrete.

[0004] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation: slope online monitoring devices are generally fixed on the slope and secured by fasteners that extend into the slope, making the devices bulky and difficult to install and deploy quickly, while also taking up a large area and being inconvenient to store. Utility Model Content

[0005] The purpose of this utility model is to provide a non-coal mine slope online monitoring device with multi-terminal data acquisition, so as to solve the problems in the above-mentioned background technology that the slope online monitoring device is bulky, inconvenient to install and deploy quickly, and has a large footprint and is inconvenient to store.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an online monitoring device for non-coal mine slopes with multi-terminal data acquisition, comprising an installation plate, wherein the installation plate integrates a microcontroller, a communication module, and a battery;

[0007] A fixed base block is fixedly connected to the bottom center of the mounting plate, and movable blocks are installed at equal intervals on the bottom of the fixed base block. The movable blocks are spliced ​​together to form a whole, and the movable block at the bottom of the whole has a conical structure.

[0008] Preferably, each of the movable blocks has an aligned opening in the middle, and a pull rope is threaded through the opening. The movable block at the bottom of the whole is fixedly connected to the pull rope. The pull rope applies tension to the equidistant movable blocks to form an integral structure. The top of the movable block has a slot, and the bottom of the movable block is fixedly connected to a connecting protrusion. The movable block is fitted into the slot on the top of the adjacent movable block through the connecting protrusion to form an integral structure.

[0009] Preferably, elastic electrodes are installed on both sides of the bottom of the movable block, and two contacts corresponding to the positions of the elastic electrodes are provided on the top of the movable block. The two contacts of the bottommost movable block form a passage, and elastic electrodes are also symmetrically distributed on both sides of the bottom of the fixed base block.

[0010] Preferably, a mounting box is fixedly connected to the top center of the mounting plate, and openings are provided at both ends of the mounting plate to form handles. Two sets of symmetrically distributed foldable solar panels are fixedly connected to the top of the mounting plate, and the foldable solar panels are symmetrically distributed on both sides of the mounting box. The foldable solar panels are fixed by elastic ropes.

[0011] Preferably, the mounting box has two independent chambers inside, one of which is rotatably connected to a winding wheel, and one end of the mounting box is rotatably connected to a knob.

[0012] Preferably, a fixing rod is fixedly connected inside the mounting box, and a winding wheel is rotatably connected to the fixing rod. A pull rope is wound around the outside of the winding wheel. The knob is provided with a limiting groove and a connecting groove inside, and the inner wall of the limiting groove is fixedly connected with equidistant limiting strips.

[0013] Preferably, the end of the fixing rod is fixedly connected with a ring-shaped limiting paddle, and the limiting paddle extends into the limiting groove. An inner ratchet ring is slidably connected inside the limiting groove, and the outer side of the inner ratchet ring is provided with a limiting groove that cooperates with the limiting strip. The inner side of the inner ratchet ring and the limiting paddle are engaged with each other, and a spring is installed between the inner ratchet ring and the inner wall of the limiting groove. A button is slidably connected inside the connecting groove, and the button abuts against the inner ratchet ring.

[0014] Preferably, a rotating plate is rotatably connected to another chamber of the mounting box, and a brush is fixedly connected to the lower end of the rotating plate. An annularly distributed induction strip is fixedly connected inside the chamber, and the induction strip and the brush are in contact with each other.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This non-coal mine slope online monitoring device with multi-terminal data acquisition uses connecting protrusions for splicing. The bottom movable block is conical, making it easier to insert into the slope. The structure of the movable block can be adjusted by pulling the rope. When it needs to be stored, the rope can be released, and the movable block can be folded to reduce its volume. The winding wheel and knob mechanism allow the rope to be extended and retracted, making it convenient for adjustment and storage.

[0017] The closed loop formed by the elastic electrodes and contacts inside the movable block can quickly respond to changes in slope displacement. When a landslide or deformation occurs on the slope, the bending of the movable block will cause the electrodes to separate from the contacts, thereby immediately breaking the loop. At this time, the microcontroller will detect the signal change, send an alarm in time, and record the timestamp, realizing automatic monitoring of landslides with extremely high sensitivity and reliability.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figure 1 - Figure 6 This utility model provides the following technical solution: an online monitoring device for non-coal mine slopes with multi-terminal data acquisition, including a mounting plate 1, which integrates a microcontroller, a communication module, and a battery; a fixed base block 2 is fixedly connected to the bottom center of the mounting plate 1, and movable blocks 3 are equidistantly distributed at the bottom of the fixed base block 2, the movable blocks 3 are spliced ​​together to form a whole, and the movable blocks 3 at the bottom of the whole have a conical structure; each movable block 3 has an aligned opening in the center, and a pull rope 4 is threaded through the opening, and the movable blocks 4 at the bottom of the whole have a conical structure. The movable block 3 is fixedly connected to the pull rope 4. The pull rope 4 applies tension to the movable blocks 3 that are evenly distributed to form an integral structure. The top of the movable block 3 is provided with a slot, and the bottom of the movable block 3 is fixedly connected with a connecting protrusion 5. The movable block 3 is fitted into the slot on the top of the adjacent movable block 3 through the connecting protrusion 5 to form an integral structure. Elastic electrodes 6 are installed on both sides of the bottom of the movable block 3, and the top of the movable block 3 is provided with two contacts corresponding to the positions of the elastic electrodes 6. The two contacts of the bottommost movable block 3 form a passage. At the same time, the fixed base block 2 is also provided with symmetrically distributed elastic electrodes 6 on both sides of the bottom.

[0027] During the use of the device, the moving block 3 is pulled by the pull rope 4, and then a force is applied to the moving block 3 in the direction of the fixed base block 2. At this time, the moving block 3 is fitted into the slot on the top of the adjacent moving block 3 by the connecting protrusion 5 to form a whole. The moving blocks 3 are mechanically engaged by the connecting protrusion 5 and are kept linearly aligned by the pre-tightening force applied by the pull rope 4. The elastic electrode 6 located at the bottom of the moving block 3 will contact each other with the contact point at the top of the moving block 3 to form a passage. At this time, the passage formed by the two contact points of the bottom moving block 3 constitutes a complete circuit.

[0028] When the movable block 3 forms an integral structure, the handles at both ends of the mounting plate 1 are used to control the movable block 3 at its bottom, thereby embedding the movable block 3 into the slope. At the same time, the mounting box 7 is installed horizontally on the slope. At this time, the elastic rope fixing the foldable solar panel 20 is untied, allowing the foldable solar panel 20 to unfold on the top of the mounting plate 1, providing power for the device to be used for a long time. When the movable block 3 is located inside the slope, if the slope landslides, the whole formed by the movable block 3 will bend to a certain extent, causing the elastic electrode 6 and the contact to separate from each other, causing the complete circuit formed inside the movable block 3 to break, thereby detecting the landslide of the slope.

[0029] The sensing rod is composed of a fixed base block 2 and a conical movable block 3 connected in series. The movable blocks are mechanically engaged by connecting protrusions 5 and are kept in a linear arrangement by a pre-tensioning force applied by a pull rope 4.

[0030] Each movable block has symmetrically arranged elastic electrodes 6 at its bottom and corresponding metal contacts at its top. When the rod is in an upright state, the elastic electrodes contact the upper contacts to form a series circuit, and the contacts of the bottom movable blocks form a closed loop through a short circuit. The closed loop is connected to the microcontroller I / O port in the mounting plate 1 via a wire. The microcontroller continuously monitors the level of this port. When the slope displacement causes the rod to bend beyond a threshold, the electrodes between any adjacent movable blocks separate, triggering a circuit break. After detecting the circuit break signal, the microcontroller immediately starts the communication module to send an alarm signal containing the device ID, and simultaneously records the break point timestamp to the local memory.

[0031] Example 2: Based on Example 1, the following structure is also disclosed: A mounting box 7 is fixedly connected to the top center of the mounting plate 1, and openings are provided at both ends of the mounting plate 1 to form handles. Two sets of symmetrically distributed foldable solar panels 20 are fixedly connected to the top of the mounting plate 1, and the foldable solar panels 20 are symmetrically distributed on both sides of the mounting box 7, and the foldable solar panels 20 are fixed by elastic ropes; the mounting box 7 has two independent chambers inside, one of which is rotatably connected to a winding wheel 8, and one end of the mounting box 7 is rotatably connected to a knob 9; a fixing rod 10 is fixedly connected inside the mounting box 7, and the winding wheel 8 is rotatably connected to the fixing rod 10, and the pull rope 4 is wound around the outside of the winding wheel 8; the knob 9 has a limiting groove 11 and a connecting groove 12 inside, and the inner wall of the limiting groove 11 is fixed. The fixed rod 10 is connected with equidistant limiting strips; the end of the fixed rod 10 is fixedly connected with annularly distributed limiting paddles 13, and the limiting paddles 13 extend into the limiting slide groove 11. The limiting slide groove 11 is slidably connected with an inner ratchet ring 14, and the outer side of the inner ratchet ring 14 is provided with a limiting groove that cooperates with the limiting strips. The inner side of the inner ratchet ring 14 and the limiting paddles 13 are engaged with each other, and a spring 15 is installed between the inner ratchet ring 14 and the inner wall of the limiting slide groove 11. A button 16 is slidably connected inside the connecting slide groove 12, and the button 16 abuts against the inner ratchet ring 14. The other chamber of the mounting box 7 is rotatably connected with a rotating plate 17, and the lower end of the rotating plate 17 is fixedly connected with a brush 18. The chamber is fixedly connected with annularly distributed induction strips 19, and the induction strips 19 and the brush 18 are in contact with each other.

[0032] The pull rope 4 applies tension to the winding wheel 8 by winding it around the outside of the winding wheel 8 and by rotating the winding wheel 8. The air pump drives the winding wheel 8 to rotate by rotating the knob 9. During the rotation of the knob 9, the inner ratchet ring 14 inside the limiting slide groove 11 will rotate. Since the inner ratchet ring 14 and the limiting plate 13 form an engaging structure, the rotation of the inner ratchet ring 14 outside the limiting plate 13 can only be in one direction. Therefore, when the knob 9 drives the winding wheel 8 to rotate, it can only be in one direction, thereby applying tension to the winding wheel 8.

[0033] When the pressure of the winding wheel 8 needs to be released, press button 16. Button 16 drives the inner ratchet ring 14 to slide inside the limiting groove 11. At this time, the inner ratchet ring 14 will compress the spring 15, and the inner ratchet ring 14 will be misaligned with the limiting paddle 13, so that the limiting paddle 13 and the inner ratchet ring 14 are separated from each other. At this time, the rotation of the inner ratchet ring 14 will not be restricted, and the rotation of the knob 9 and the winding wheel 8 will not be restricted. At this time, the pressure applied by the winding wheel 8 to the pull rope 4 will be released, and the mutual fixing force applied by the pull rope 4 to the movable block 3 will be released. At this time, each movable block 3 can move arbitrarily outside the pull rope 4. At this time, the movable block 3 can be folded and stored.

[0034] After the mounting plate 1 is installed, the mounting box 7 is horizontally installed on the slope. The rotating plate 17 will rotate inside the mounting box 7 and tilt downwards due to gravity. At this time, the brush 18 at the bottom of the rotating plate 17 will come into contact with the induction strip 19. When the slope changes, the rotating plate 17 will rotate inside the mounting box 7, causing the brush 18 to come into contact with different induction strips 19. Since the induction strips 19 are distributed in a ring at equal intervals inside the mounting box 7, the conductive brush 18 at the end of the rotating plate 17 and the ring-shaped induction strips 19 constitute a rotary encoder. Each induction strip corresponds to an independent resistance value, forming an angle-resistance mapping relationship. Each knob 9 is distributed at a certain angle. Therefore, the slope change can be monitored in real time through the contact between the brush 18 and different induction strips 19.
