[0019] In order to clearly and completely describe the objectives and technical solutions of the present invention and make the advantages more clearly understood, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 10 , the present invention provides a technical solution: Embodiment 1, a sensing device for monitoring slope deformation in an open-pit mine, includes: a liquid storage tank 1.

[0021] Specifically, a water distribution hose 2 is connected to the outside of the liquid storage tank 1, and a plurality of monitoring components 3 are arranged in the middle of the water distribution hose 2 at equal intervals, and the plurality of monitoring components 3 are located at the same horizontal position. The liquid storage tank 1, the water distribution hose 2 and the monitoring components 3 are kept in communication, and a certain amount of liquid (water) is added to the liquid storage tank 1. A communicating vessel is formed between the liquid storage tank 1 and the monitoring components 3, and the liquid levels of the two are kept consistent. The water distribution hose 2 itself is a flexible structure that can adapt to deformation. The monitoring components 3 are installed on the surface of the mine slope. When the slope where a monitoring component 3 is located undergoes landslide deformation, the position of the monitoring component 3 itself will drop accordingly. Secondly, the monitoring component 3 includes a monitoring vertical pipe 4, the inner cavity of the monitoring vertical pipe 4 is provided with a hollow float 44, and a flexible telescopic tube 43 is fixed on the lower side of the surface of the hollow float 44. The hollow float 44 can float in the middle of the inner cavity of the monitoring vertical pipe 4 under the influence of the buoyancy of the liquid, and the lower end of the flexible telescopic tube 43 is fixedly connected to the bottom of the inner cavity of the monitoring vertical pipe 4. The lower end of the inner cavity of the monitoring vertical pipe 4 is provided with two symmetrically distributed hose interfaces 42, and the hose interfaces 42 are connected with the water distribution hose 2. The inner cavity of the liquid storage tank 1 and the inner cavity of the monitoring vertical pipe 4 are connected through the water distribution hose 2, and the liquid level height of the inner cavity of the monitoring vertical pipe 4 is kept constant. According to the above, when the overall position of the monitoring component 3 drops, the position of the monitoring vertical pipe 4 moves downward, but the liquid level in the inner cavity of the monitoring vertical pipe 4 remains unchanged relative to the liquid storage tank 1. , so the hollow float 44 will move vertically relative to it in the inner cavity of the monitoring vertical pipe 4. By detecting the height position of the hollow float 44 in the inner cavity of the monitoring vertical pipe 4, the displacement of the monitoring vertical pipe 4 can be detected. In addition, if the slope in the area where the liquid storage tank 1 is located undergoes landslide deformation, the liquid level in the inner cavity of the liquid storage tank 1 drops, so the liquid levels in the inner cavities of all the monitoring vertical pipes 4 also drop. In other words, the positions of the hollow floats 44 in the inner cavities of all the monitoring vertical pipes 4 will move downward in the inner cavity of the monitoring vertical pipe 4. By detecting the change in the position of a single hollow float 44 in the present device, or the change in the positions of all the hollow floats 44, it can be distinguished whether the area of ​​the slope landslide deformation is specifically located at the location of the monitoring component 3 or at the location of the liquid storage tank 1. In addition, a sensor component 5 is installed at the lower end of the monitoring vertical pipe 4; Side covers 51 are provided on both sides of the sensor assembly 5, and a semiconductor photosensitive plate 511 is provided on the inner side of one side cover 51. A turntable 52 is rotatably installed in the inner cavity of the sensor assembly 5, and a laser emitter 521 is fixedly installed on one side of the turntable 52, and the emitting end of the laser emitter 521 is facing the semiconductor photosensitive plate 511. The semiconductor photosensitive plate 511 is composed of the following key materials and structures: ① PIN-type silicon photodiode, which is composed of a P-type layer, an intrinsic layer I layer and an N-type layer. The laser spot emitted by the laser emitter 521 is irradiated on the intrinsic layer of the semiconductor photosensitive plate 511 to generate electron-hole pairs; ② electrode structure, electrodes are provided at both ends (such as left-right symmetry), and the position of the laser spot emitted by the laser emitter 521 is calculated by measuring the photocurrent distribution (along the length direction of the semiconductor photosensitive plate 511); ③ surface resistance layer, whose photosensitive surface is covered with a uniform high-resistance layer (such as a diffused resistor or a thin film electrode) Resistance), when the laser spot is irradiated, the current is divided into electrodes according to the position, and the center of the spot is accurately calculated by the current ratio (I1-I2) / (I1+I2); in addition, a connecting rope 541 is provided on the other side of the turntable 52 to drive its rotation, and the upper end of the connecting rope 541 passes through the top plate of the sensor assembly 5 and the lower end surface of the monitoring vertical pipe 4 in sequence, and extends to the inner cavity of the flexible telescopic tube 43, and the upper end of the connecting rope 541 is fixedly connected to the hollow float 44. Since the sensor assembly 5 is integrally installed on the lower end surface of the monitoring vertical pipe 4, when the position of the monitoring vertical pipe 4 moves downward, the position of the sensor assembly 5 will move downward accordingly. When the hollow float 44 moves up and down in the inner cavity of the monitoring vertical pipe 4, the hollow float 44 can drive the turntable 52 to rotate through the connecting rope 541, thereby changing the irradiation position of the laser emitter 521 on the semiconductor photosensitive plate 511, thereby realizing the monitoring of the movement of the hollow float 44 in the inner cavity of the monitoring vertical pipe 4; Based on the above, it can be seen that when the slope where the monitoring component 3 is located undergoes landslide deformation, the monitoring vertical pipe 4 and the sensor component 5 are lowered. At this time, the hollow float 44 moves upward in the inner cavity of the monitoring vertical pipe 4, and the hollow float 44 pulls the connecting rope 541, thereby driving the turntable 52 to rotate. When the turntable 52 rotates, the laser emitter 521 rotates accordingly, and the position of the laser spot emitted by the laser emitter 521 on the semiconductor photosensitive plate 511 changes accordingly. Therefore, the semiconductor photosensitive plate 511 can determine whether the slope at that location has undergone landslide deformation by detecting the position of the light spot.

[0022] In order to facilitate the staff to judge the height position of the hollow float 44 in the inner cavity of the monitoring vertical pipe 4, the present application also has a scale line 41 vertically opened on the surface of the monitoring vertical pipe 4. The staff observes the height position of the hollow float 44 in the inner cavity of the monitoring vertical pipe 4 through the scale line 41, and can also judge whether the slope here has landslide deformation. In addition, during the installation of the monitoring component 3, the staff also needs to use the scale line 41 to judge the height position of the hollow float 44 in the inner cavity of the monitoring vertical pipe 4. The middle part of the lower end surface of the monitoring vertical pipe 4 is recessed inward to form a boss 45, and the boss 45 is fixedly connected to the lower end of the flexible telescopic tube 43. A through hole 451 for the connection rope 541 to pass through is opened at the bottom of the groove of the boss 45. Figure 4 and Figure 7 As shown, the flexible telescopic tube 43 is mainly used to isolate the liquid in the inner cavity of the monitoring vertical tube 4 from the connecting rope 541, so as to prevent the liquid in the inner cavity of the monitoring vertical tube 4 from seeping into the inner cavity of the sensor assembly 5 along the surface of the connecting rope 541 and affecting the normal operation of its internal electrical components.

[0023] In order to ensure that the connecting rope 541 can drive the turntable 52 to rotate when it is pulled, the present application also has a recessed groove 522 on the other side of the turntable 52, and an annular inner tooth groove 523 is provided on the inner wall of the recessed groove 522. A transmission gear 55 that meshes with the recessed groove 522 and transmits power is provided in the inner cavity of the recessed groove 522. A winding roller 54 is fixed to one side of the transmission gear 55, and the lower end of the connecting rope 541 is wound around the outside of the winding roller 54. Figure 6 As shown, when the upper end of the connecting rope 541 is pulled, the connecting rope 541 will pull the winding roller 54 to rotate, and the transmission gear 55 will rotate accordingly. The transmission gear 55 can drive the turntable 52 to rotate through the meshing transmission with the internal tooth groove 523. In addition, since a reduction meshing transmission is formed between the winding roller 54, the transmission gear 55 and the turntable 52, the connecting rope 541 only needs a small pulling force to drive the turntable 52 to rotate. In other words, the liquid buoyancy of the hollow float 44 is sufficient to pull the connecting rope 541 upward.

[0024] In order to reel in the winding roller 54, the present application also has a rotating shaft 53 fixed at one end of the winding roller 54, and one end of the rotating shaft 53 is rotationally connected to the other side cover plate 51 for positioning the winding roller 54 to ensure that the winding roller 54 only rotates, thereby avoiding disengagement between the transmission gear 55 and the inner tooth groove 523. A torsion spring 531 is sleeved on the outer side of the rotating shaft 53, and the two ends of the torsion spring 531 are respectively fixedly connected to the winding roller 54 and the other side cover plate 51. The torsion spring 531 is set to reset the rotation of the winding roller 54. When the connecting rope 541 is not subjected to the tension of the hollow float 44, the torsion spring 531 can drive the winding roller 54 to rotate in the opposite direction, thereby realizing the reeling of the connecting rope 541.

[0025] In order to position the installation of the sensor assembly 5, the present application also has a positioning cylinder 56 fixedly provided on the top plate of the sensor assembly 5, and the connecting pull rope 541 movably passes through the inner cavity of the positioning cylinder 56. The positioning cylinder 56 is movably inserted into the inner cavity of the boss 45 from bottom to top. The setting of the positioning cylinder 56 is mainly used to maintain a plug-in fit with the boss 45, thereby facilitating the positioning of the installation of the sensor assembly 5 and ensuring that the connecting pull rope 541 is always in a vertical state. The sensor assembly 5 as a whole is fixed to the lower end face of the monitoring vertical pipe 4 by bolts.

[0026] In order to install the semiconductor photosensitive plate 511, the semiconductor photosensitive plate 511 of the present application is set to an arc structure and is concentric with the turntable 52. The semiconductor photosensitive plate 511 is fixed to the inner side of the side cover 51 and a gap is left between the turntable 52. The position of the semiconductor photosensitive plate 511 itself remains fixed and does not contact the turntable 52. Therefore, the turntable 52 will not affect the position of the semiconductor photosensitive plate 511 when it rotates. The semiconductor photosensitive plate 511 is set to an arc structure, which can ensure that the distance between the emitting end of the laser emitter 521 and the surface of the semiconductor photosensitive plate 511 remains constant, avoiding the change in the path length of the laser emitted by the laser emitter 521 and causing the spot intensity to weaken, thereby avoiding the semiconductor photosensitive plate 511 The detection results will have unnecessary errors. The laser emitter 521 coincides with the radial direction of the turntable 52. Therefore, the laser emitted by the laser emitter 521 can always be vertically irradiated on the surface of the semiconductor photosensitive plate 511. A controller 512 and a wireless transmission module 513 are provided on the surface of a side cover plate 51. The controller 512 is electrically connected to the semiconductor photosensitive plate 511. The controller 512 is used to receive and process the light spot signal received by the semiconductor photosensitive plate 511. The controller 512 cooperates with the semiconductor photosensitive plate 511 to form a PSD position sensitive detector known in the prior art. The wireless transmission module 513 is provided to transmit the detection result signal of the device to a designated terminal, which is convenient for the staff to view in time.

[0027] In order to ensure that the monitoring vertical pipe 4 remains vertical during installation, the present application also has an adjustment ball shell 6 provided at the upper end of the monitoring vertical pipe 4, and an annular positioning frame 61 adapted thereto is movably sleeved on the outer middle portion of the adjustment ball shell 6. Figure 3As can be seen, the adjusting spherical shell 6 can rotate in any direction within the annular positioning frame 61. Connecting rods 62 are fixed on both sides of the surface of the annular positioning frame 61. One end of each connecting rod 62 is provided with a mounting seat 7, and the mounting seat 7 is fixed to the surface of the mine slope through an anchor rod 71. When installing the monitoring vertical pipe 4 of this device, the mounting seat 7 is first fixed to the slope surface. Since the adjusting spherical shell 6 can rotate inside the annular positioning frame 61, the monitoring vertical pipe 4 can correct its own position under its own gravity, ensuring that the monitoring vertical pipe 4 remains vertical during installation.

[0028] To avoid the liquid level height in the monitoring vertical pipe 4 being affected by the air pressure inside the cavity of the monitoring vertical pipe 4, this application also has an opening provided on the lower side of the adjusting spherical shell 6 and covering the outer side of the upper end of the monitoring vertical pipe 4. A connecting ring 64 is fixed between the inner wall of the adjusting spherical shell 6 and the monitoring vertical pipe 4, and air vents 641 are provided on the surface of the connecting ring 64. The connecting ring 64 is used to fixedly connect the adjusting spherical shell 6 and the monitoring vertical pipe 4, and the air vents 641 are provided to connect the cavity of the monitoring vertical pipe 4 with the external environment, avoiding the liquid level in the cavity of the monitoring vertical pipe 4 being affected by the pressure inside the cavity of the monitoring vertical pipe 4. A knob seat 651 is fixed on the outer side of the annular positioning frame 61, and a fastening knob 65 is provided in the middle of the knob seat 651. When the fastening knob 65 is tightened, it presses against the surface of the adjusting spherical shell 6 through friction. The fastening knob 65 can be used to fix the position of the adjusting spherical shell 6. After the monitoring vertical pipe 4 of this device is installed, by tightening the fastening knob �5, the adjusting spherical shell 6 can be kept relatively fixed with the annular positioning frame 61, thus preventing the monitoring vertical pipe 4 of this device from swaying randomly under the influence of the surrounding wind after installation.

[0029] To zero the sensor assembly 5 after the monitoring vertical pipe 4 is installed, this application also has a connecting slider 63 fixed at one end of the connecting rod 62, and a cavity 631 is provided inside the connecting slider 63. A guiding frame ۷2 is fixedly installed on the surface of the mounting seat 7, and the guiding frame 72 is in a "U" shape. The connecting slider 63 is movably sleeved outside the guiding frame 72 through the cavity 631, as Figure 10 and Figure 9 As can be seen, the connecting slider 63 can slide a certain distance along the length direction of the guiding frame 72. By sliding the connecting slider 63, the relative position between the adjusting spherical shell 6 and the mounting seat 7 can be changed, and thus the height position where the monitoring vertical pipe 4 is located can be changed. Since the liquid level height inside the monitoring vertical pipe 4 is constant, by adjusting the height position of the monitoring vertical pipe 4, the height position of the hollow floating ball 44 inside the monitoring vertical pipe ۴ can be adjusted, thereby enabling zeroing of the sensor assembly 5.

[0030] In order to facilitate the positioning of the connecting slider 63 on the guide frame 72, the cross-sectional dimensions of the openings at both ends of the cavity 631 of the present application are larger than the cross-sectional dimensions of the middle portion, and the inner wall of the cavity 631 is provided with two groups of latch teeth 632 which are symmetrically distributed in the center, and the latch teeth 632 are latched on the surface of the guide frame 72, and the cavity 631 is set to a structure with large ends and small middle, so that the connecting slider 63 can be tilted at a certain angle on the outside of the guide frame 72. When the staff slightly pulls the connecting rod 62 upward to rotate, the latch teeth 632 can be separated from the surface of the guide frame 72, and the connecting slider 63 can slide freely in the length direction of the guide frame 72. When the operator loosens the connecting rod 62, the gravity of the monitoring vertical pipe 4, the adjustment ball shell 6 and other structures can drive the connecting rod 62 to rotate slightly downward. At this time, the connecting slider 63 rotates accordingly, and the locking teeth 632 can be clamped on the surface of the guide frame 72, thereby realizing the sliding positioning of the connecting slider 63. In other words, the position of this device remains stable without active operation by the staff. In addition, in order to improve the positioning effect of the connecting slider 63, a rubber layer known in the prior art can be bonded and fixed to the surface of the guide frame 72, or a tooth groove that meshes with the locking teeth 632 can be opened on the surface of the guide frame 72. No further details will be given here.
