Description

Technical Field

[0001] The present invention relates to the technical field of natural disaster monitoring and early warning, and more particularly to a deformation monitoring device for geological landslides. Background Art

[0002] Landslides are highly destructive geological hazards that often cause significant casualties and economic losses. Real-time monitoring of their precursor deformation is a key component of disaster early warning. The expansion of surface cracks is a key sign of the separation of the sliding mass from the stable rock and soil. Accurately capturing these changes can provide key data for early warning.

[0003] Currently, landslide crack monitoring technologies primarily include manual measurement, crack meter monitoring, and rope-type crack monitoring. Manual measurement relies on periodic data collection using tools. While cost-effective, it suffers from significant shortcomings such as low efficiency and the inability to achieve real-time monitoring, making it difficult to meet the timeliness requirements of modern disaster monitoring. Crack meter monitoring utilizes various types of instruments, including resistive, capacitive, and LVDT instruments, to achieve high-precision, high-frequency crack width measurements, significantly improving technical accuracy. However, installation location is limited in some scenarios.

[0004] The rope-type crack monitoring method, with its simple structure, low cost, and easy installation and operation, is particularly suitable for scenarios where the monitoring point needs to be set far away from the crack edge. When restricted by avoiding interference with the natural development of the crack or special installation locations, traditional short-baseline crack meters are difficult to use directly. By integrating sensors on the rope, rope-type monitoring can achieve remote and real-time crack width monitoring.

[0005] However, the existing rope-type monitoring technology has obvious defects: during the monitoring process, the rope is usually exposed to the surface and is easily interfered with by external factors such as snow, debris, rolling gravel, and fallen branches. Such interference will cause abnormal changes in the rope length that are not caused by crack deformation, which will lead to misjudgments in remote monitoring and frequent false data of "sudden increase" in crack width. Once a misjudgment occurs, technical personnel are required to go to the site for investigation immediately, resulting in a large waste of manpower and material resources. Although the existing technology has attempted to introduce visual sensors or cameras for auxiliary monitoring, this solution not only increases the equipment maintenance cost, but also in complex outdoor environments, the sensors or cameras are easily blocked, making it difficult to achieve long-term and stable auxiliary monitoring effects, and it cannot fundamentally solve the interference problem of rope-type monitoring.

[0006] Therefore, in view of the above technical defects, it is necessary to propose a deformation monitoring device for geological landslides. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0043] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0044] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition or explanation in subsequent drawings.

[0045] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0046] Furthermore, the terms "parallel" and "perpendicular" do not necessarily mean that the components must be absolutely parallel or perpendicular, but rather that they can be slightly tilted. For example, "parallel" simply means that the direction is more parallel than "perpendicular," not that the structure must be completely parallel, but rather that it can be slightly tilted.

[0047] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0048] As attached Figure 1 To the attached Figure 8 As shown: A deformation monitoring device for geological landslides, including a monitoring pier body 1, a pull rope 12, a fixing seat 2, a bracket 21, a pull wire mechanism 3 and an energy storage mechanism 5, wherein the monitoring pier bodies 1 include two, and the two monitoring pier bodies 1 are respectively arranged on the left and right sides of the ground crack, and the two ends of the pull rope 12 are respectively connected to the monitoring pier bodies 1 on the left and right sides. After the connection, the pull rope 12 can be kept taut. The fixing seat 2 includes one, and is fixedly arranged in the middle of the two monitoring pier bodies 1 along the front and back straight direction. The bracket 21 is an "n"-shaped frame and is installed on the upper surface of the fixing seat 2. The pull wire mechanism 3 is fixedly arranged on the right side of the inner wall of the bracket 21, and the energy storage mechanism 5 is relatively arranged on the left side of the inner wall of the bracket 21, and one end of the pull rope 12 passes through the top of the pull wire mechanism 3 and the energy storage mechanism 5.

[0049] The two ends of the pull rope 12 pass through the outlet 15 and contact each other with the inner end surface of the winding drum. At the same time, a set of constant force springs 13 are provided in the front of the winding drum along the inner cavity. One end of the constant force spring 13 is connected to the end of the pull rope 12 entering the inner cavity. When in use, the constant force springs 13 at the two monitoring pier bodies 1 can apply tension to the two ends of the pull rope 12. Under the action of the tension, the pull rope 12 can be kept in a straight and taut state. Similarly, when external debris (accumulated snow, rolling gravel or fallen branches) falls on the pull rope 12, the weight will cause a drag force on the two ends of the pull rope 12. During the dragging process, the constant force spring 13 can be pulled up, and the guide plate 11 can also be driven to rotate.

[0050] Next, an angle sensor 14 is also installed at the connecting shaft of the guide disc 11. This design allows the pull rope 12 to trigger the angle sensor 14 when it drives the guide disc 11 to rotate. The signal received by the angle sensor 14 is then transmitted remotely to the monitoring station, allowing the staff at the monitoring station to compare the data and thus obtain timely information about the terrain conditions at the location. In addition, it should be noted that the remote method here belongs to existing wireless communication technology. For example, common wireless signal transmission methods include but are not limited to:

[0051] Wireless radio frequency communication (RF): transmits data to a receiving device within a certain distance via radio frequency signals and is widely used in industrial automation and remote monitoring.

[0052] 4G / 5G communication technology: provides longer-distance, high-bandwidth wireless transmission, ensuring the timeliness and integrity of data when it needs to be transmitted to a remote monitoring station.

[0053] Furthermore, a guide wheel 16 is rotatably provided at the front end and the rear end of the inner wall of the outlet 15, wherein the two guide wheels 16 are spaced apart, and one end of the pull rope 12 passes through the gap between the inner walls of the two guide wheels 16. At the same time, a connecting column 17 is rotatably provided below the inner wall of the opening along the straight line in front. The connecting column 17 is used to support the pull rope 12, and the pull rope 12 is also in contact with the outer surface of the connecting column 17. This design allows the guide wheel 16 and the connecting column 17 to contact the pull rope when the pull rope 12 is moved by the drag force, thereby reducing the friction with the opening during contact, thereby avoiding friction breakage during use.

[0054] Figure 1 、 Figures 3 to 6As shown, the wire pulling mechanism 3 includes: a first fixed plate 31, a connecting seat 37, a connecting plate 4 and a wire hook groove 41, wherein the first fixed plate 31 is fixedly arranged on the right side of the inner wall of the bracket 21 in a front-to-back straight line, and the upper surface of the first fixed plate 31 and the top end surface of the inner wall of the bracket 21 are spaced apart from each other, the connecting seat 37 is a "concave" shaped plate body, and is slidably arranged on the left side of the first fixed plate 31, the connecting plate 4 is a rectangular plate body, and is slidably arranged on the inner wall surface of the connecting seat 37 in a vertical direction, the wire hook groove 41 is opened on the upper surface of the connecting plate 4, and the wire hook groove 41 is also connected to the left and right sides of the connecting plate 4, and one end of the pull rope 12 passes through the inner middle end of the wire hook groove 41. This design allows the connecting seat 37 to move back and forth on the left side of the first fixed plate 31. After the movement, the taut drawstring 12 can be pulled through the hook groove 41, and the sliding design of the connecting plate 4 can release the pulled drawstring 12, so that the drawstring 12 can rebound quickly after release. During the rebound process, the debris on the drawstring 12 can be quickly shaken off, and after shaking off, the drawstring 12 can return to its original state.

[0055] The first fixing plate 31 has a rectangular mounting slot 32 along the left side. A screw rod 33 is rotatably mounted along the middle end of the inner wall of the mounting slot 32. A limit rod 36 is fixedly mounted above and below the screw rod 33. A threaded block 35 is threadedly mounted on the screw rod 33. The upper and lower ends of the threaded block 35 pass through the limit rod 36 respectively, and one end of the connecting seat 37 is connected to the threaded block 35. At the same time, a protective cover is also provided on the rear side of the bracket 21 through the mounting bracket 21. Then, a motor 34 is provided inside the protective cover, wherein the drive shaft of the motor 34 is also connected to the screw rod 33. This design allows the motor 34 to drive the screw rod 33 to rotate when it is started, thereby driving the threaded block 35 to move forward and backward. In addition, to facilitate maintenance by staff, the motor 34 can also be remotely controlled, that is, the motor 34 can be remotely controlled to be turned on or off using existing wireless communication technology.

[0056] Furthermore, a second vertical slot 38 of rectangular structure is vertically opened on the inner wall surface of the connecting seat 37. A vertical rod 381 is fixedly installed in the second vertical slot 38. Then, a first slider 382 is adapted and installed along the outer surface of the vertical rod 381 in the second vertical slot 38. One end of the first slider 382 is also connected to the connecting plate 4. Then, a first spring 383 is sleeved along the outer surface of the vertical rod 381 below the first slider 382, and one end of the first spring 383 is also connected to the bottom end of the inner wall of the second vertical slot 38. This design allows the connecting plate 4 to slide up and down on the inner end of the connecting seat 37 via the first slider 382, and after sliding downward, it can be reset by the elastic force of the first spring 383.

[0057] The interior of the connecting plate 4 is connected to the left side with a rectangular slot 44, and a rectangular limit bar 45 is slidably arranged in the slot 44, wherein a tooth mark groove 46 is provided at the middle end of the upper surface of the limit bar 45, and a connecting rod 42 is rotatably arranged above the tooth mark groove 46 along the front and rear direction of the inner wall of the slot 44, and a second gear 47 is fixedly provided on the connecting rod 42, and the second gear 47 is also meshed with the tooth mark groove 46. This design allows the second gear 47 to contact the tooth mark groove 46 when the connecting rod 42 is rotated, and after contact, it can drive the limit bar 45 to move to the outside of the connecting plate 4.

[0058] At the same time, a first vertical slot 371 of a rectangular structure is vertically opened on both sides of the inner wall of the connecting seat 37, and one end of the connecting rod 42 extends into the first vertical slot 371, and then a first gear 43 is fixedly set at the extended end of the connecting rod 42, and a rack 372 is set at the lower front end of the inner wall of the first vertical slot 371. When the connecting plate 4 drives the connecting rod 42 to slide downward, the first gear 43 can be engaged with the rack 372. This design allows the first gear 43 to be engaged with the rack 372 when the connecting plate 4 continues to move downward. During the contact process, the connecting rod 42 can be driven to rotate, and then the limiting bar 45 can be provided with moving power, so that the limiting bar 45 can be extended on the left side of the connecting plate 4. Similarly, when the connecting plate 4 is reset upward, the first gear 43 can drive the connecting rod 42 to reverse, so that the limiting bar 45 can be returned to its original position.

[0059] like Figures 3 to 8As shown, the energy storage mechanism 5 includes: a second fixing plate 51, a horizontal end surface 55, an inclined end surface 56, a lifting assembly and a docking plate 6, wherein the second fixing plate 51 is fixedly arranged on the left side of the inner wall of the bracket 21 along the front-to-back direction, and the upper surface of the second fixing plate 51 is spaced from the top surface of the inner wall of the bracket 21, the horizontal end surface 55 is a flat end, and is integrally formed with the middle end of the bottom of the second fixing plate 51, the inclined end surface 56 is a downwardly extending inclined end, and is integrally formed with both sides of the bottom of the second fixing plate 51, and the horizontal end surface 55 and the inclined end surface 56 have a height difference;

[0060] The lifting assembly includes two groups, which are movably arranged on both sides of the top of the second fixed plate 51, and the docking plate 6 is movably arranged on the left side of the second fixed plate 51. At the same time, the docking plate 6 is also opposite to the connecting plate 4, and the lower ends of the docking plate 6 and the connecting plate 4 also extend toward the bottom of the second fixed plate 51. Then a support block 62 is fixed between the bottom lower ends of the docking plate 6 and the connecting plate 4, and a moving wheel 48 is also provided above the support block 62, wherein the wheel axle of the moving wheel 48 is rotatably connected to the corresponding docking plate 6 or connecting plate 4, and the moving wheel 48 is also in contact with the horizontal end surface 55 and the inclined end surface 56. This design allows the moving wheel 48 and the docking plate 6 to move together when the connecting plate 4 moves, and when the moving wheel 48 moves to both sides of the bottom of the second fixed plate 51, the connecting plate 4 and the docking plate 6 will be driven downward due to the change in the drop. That is, when the connecting plate 4 drives the moving wheel 48 to move at the middle position of the second fixed plate 51, the wire hook groove 41 above the connecting plate 4 can protrude from the top of the first fixed plate 31 and the second fixed plate 51. Similarly, when the moving wheel 48 moves to the left and right sides of the second fixed plate 51, the connecting plate 4 will move downward due to the change in the drop, so that the wire hook groove 41 can be kept away from the top of the first fixed plate 31 and the second fixed plate 51. After it is away from the top, the pull rope 12 can be released. At this time, the pull rope 12 can be blocked by the lifting assembly after rebounding, and the rebound force of the pull rope 12 can be stored after being blocked.

[0061] Furthermore, a first middle groove 54 of a rectangular block is opened in the middle of the right side of the second fixed plate 51, and a first transverse groove 52 is opened in a straight line at the left and right sides of the upper end of the inner wall of the first middle groove 54, wherein the first transverse grooves 52 are arranged corresponding to each other, and the first transverse groove 52 is also interconnected with the first middle groove 54, and a second transverse groove 53 is opened in a straight line at the left and right sides of the lower end of the inner wall of the first middle groove 54, wherein the second transverse grooves 53 are arranged corresponding to each other, and the second transverse groove 53 is also interconnected with the first middle groove 54, and the first transverse groove 52 and the second transverse groove 53 are separated from each other, and the inner wall height of the first middle groove 54 is greater than the sum of the inner wall heights of the first transverse groove 52 and the second transverse groove 53, and when the moving wheel 48 moves to the horizontal end face 55, its opening can be opposite to the first transverse groove 52, and when the moving wheel 48 moves to the inclined end face 56, the limit bar 45 in its opening can move and extend into the second transverse groove 53. This design allows the top of the connecting plate 4 to protrude from the top of the fixed plate when the connecting plate 4 drives the moving wheel 48 to move to the horizontal end surface 55, so that the taut pull rope 12 can be pulled after protruding, so that the pull rope 12 can be moved to the left or right side of the inner wall of the bracket 21. When the connecting plate 4 drives the moving wheel 48 to move to the inclined end surface 56, its inclined end can drive the connecting plate 4 to move downward, so that the hooking groove 41 can release the hooked pull rope 12, and the pull rope 12 can rebound after release.

[0062] When the moving wheel 48 moves to the horizontal end surface 55, the limiting bar 45 can enter the first transverse groove 52 smoothly. When the moving wheel 48 moves to the inclined end surface 56, the connecting plate 4 will drive the opening to move downward, so that the opening can be opposite to the second transverse groove 53. During the relative process, one end of the limiting bar 45 can be pushed into the second transverse groove 53 and locked. In this way, when the moving wheel 48 moves from the inclined end surface 56 to the horizontal end surface 55 again, the connecting plate 4 cannot move upward due to the limiting effect of the limiting bar 45. This can prevent the connecting plate 4 from contacting the pull rope 12 in the energy storage state. Finally, when the limiting bar 45 enters the first intermediate groove 54 from the second transverse groove 53, it will automatically reset due to the lack of obstruction, so that the upper end of the connecting plate 4 can be in contact with the pull rope 12 whose elastic force has been released again. That is, when the connecting plate 4 continues to move toward the first middle groove 54, its lifting assembly first releases the energy-stored pull rope 12. Due to the rapid rebound force of the pull rope 12, it can exceed the moving speed of the connecting plate 4 and reach the middle position in the bracket 21. When the connecting plate 4 that arrives later moves to the first middle groove 54, it can drive the wire hook groove 41 to move upward and hook the pull rope 12, so that the pull rope 12 can be dragged to move in another direction.

[0063] Furthermore, a second intermediate groove 57 of a rectangular block structure is opened in the middle of the left side of the second fixed plate 51, and a third transverse groove 58 is opened in a straight line on the left and right sides of the inner wall of the second intermediate groove 57, wherein the third transverse grooves 58 are arranged corresponding to each other, and the third transverse groove 58 is also interconnected with the second intermediate groove 57. At the same time, the inner wall height of the third transverse groove 58 is less than the inner wall height of the second intermediate groove 57, and a cylindrical pressure rod 61 is fixedly provided along the upper end position of one end of the docking plate 6 facing the second intermediate groove 57, and one end of the pressure rod 61 extends straight into the second intermediate groove 57. This design allows the pressure rod 61 to move in a straight line toward the upper end area of the third transverse groove 58 when the connecting plate 4 drives the moving wheel 48 to move at the horizontal end surface 55. Similarly, when the moving wheel 48 moves at the inclined end surface 56, the pressure rod 61 can be moved toward the lower end, so that the pressure rod 61 can reach the lower end area of the third transverse groove 58. Finally, due to the blocking effect of the limiting strip 45 on the connecting plate 4, when the moving wheel 48 returns from the inclined end surface 56 to the horizontal end surface 55, its pressure rod 61 will still move in a straight line at the lower end area of the third transverse groove 58.

[0064] like Figure 7 and Figure 8 As shown, the lifting assembly includes: a receiving groove 59, a lifting plate 591, a first pressure block 592, a second pressure block 593 and a stopper 594, wherein the receiving groove 59 is respectively opened at the left and right sides of the interior of the second fixed plate 51, and the receiving groove 59 is also connected with the upper surface of the second fixed plate 51 and the inner surface of the third transverse groove 58. The lifting plate 591 is slidably set in the receiving groove 59, the first pressure block 592 is a rectangular structure, and is fixedly set at the upper end of the front side of the lifting plate 591 in a straight line direction, and the first pressure block 592 is connected to the first pressure block 593 at one end toward the second intermediate groove 57. An upwardly extending inclined end is provided between the top end surfaces of the block 592, and the lower end of the inclined end is arranged opposite to the pressure rod 61. The second pressure block 593 is in the shape of a square block and is fixedly arranged at the lower end of the front side surface of the lifting plate 591 in a straight line direction, and the end of the second pressure block 593 facing away from the second middle groove 57 is also provided with an inclined end. When the moving wheel 48 moves to the inclined end surface 56, its pressure rod 61 can be arranged opposite to the inclined end of the second pressure block 593. The stop block 594 is arranged on the upper surface of the second fixed plate 51, and the lower end of the stop block 594 is connected to the upper surface of the lifting plate 591.

[0065] This design allows the pressure rod 61 to move toward the inclined end of the first pressure block 592 when the connecting plate 4 drives the moving wheel 48 to move at the horizontal end surface 55. After continuous movement, the pressure rod 61 can apply downward pressure to the first pressure block 592, thereby driving the lifting plate 591 and the stop block 594 to move downward. At this time, the upper surface of the second fixed plate 51 can form a flat end surface, which is conducive to allowing the connecting plate 4 to drive the pull rope 12 to move. When the pull rope 12 moves away from the position of the stop block 594, the pressure rod 61 disengages from the first pressure block 592, thereby allowing the lifting plate 591 to drive the stop block 594 to reset upward. After resetting, the stop block 594 can resist the right side of the pull rope 12, so that when the pull rope 12 rebounds after being released, it can be hooked by the stop block 594 and store energy. When the moving wheel 48 moves to the inclined end face 56, the docking plate 6 will drive the pressure block to move to the inner lower end area of the third transverse groove 58. Then, when the moving wheel 48 moves from the inclined end face 56 to the horizontal end face 55, due to the blocking effect of the limit bar 45, the connecting plate 4 and the docking plate 6 will move in a straight line direction, so that the pressure rod 61 can contact the inclined end of the second pressure block 593. After the contact, it can drive the lifting plate 591 and the stop block 594 to move downward. At this time, the energy-stored pull rope 12 can rebound quickly, and during the rebound process, the debris on the pull rope 12 can be shaken off and cleaned.

[0066] Furthermore, the lower surface of the first pressure block 592 and the upper surface of the second pressure block 593 are spaced apart. This design allows a receiving channel for the pressure rod 61 to pass through to be formed between the first pressure block 592 and the second pressure block 593. In this way, when the docking plate 6 drives the pressure rod 61 to move left and right, there will be no interference problem.

[0067] Furthermore, to ensure that the block 594 can accurately hook the pull rope 12, the sum of the horizontal lengths of the first pressure block 592 and the first middle groove 54 should be greater than the sum of the horizontal lengths of the block 594 and the first middle groove 54. This design allows the lifting plate 591 and the block 594 to be reset only after the connecting plate 4 drives the pull rope 12 away from the position of the block 594. In this way, the block 594 can accurately rest against one side of the pull rope 12, and the pull rope 12 can be normally hooked by the block 594 after being released.

[0068] At the same time, to ensure that the pull rope 12 can rebound first, the second pressure block 593 should be located in the middle of the third transverse groove 58. This design allows the pressure rod 61 to trigger the lifting plate 591 to retract when the connecting plate 4 drives the docking plate 6 to move to the middle of the third transverse groove 58. This allows the pull rope 12 to rebound quickly after retraction, thereby returning to the middle position of the bracket 21. In addition, it should be noted that to reduce the moving speed of the connecting plate 4, the motor 34 can be a reduction motor 34, so that the connecting seat 37 and the connecting plate 4 can move at a slow speed, thus ensuring that the pull rope 12 can be dragged accurately.

[0069] Furthermore, a third vertical groove 595 is vertically opened on the inner wall surface of the accommodating groove 59, wherein the third vertical groove 595 is provided with a second slider 596 sliding along the inner upper end, and one end of the second slider 596 is connected to the lifting plate 591, and then a second spring 597 is provided between the lower part of the second slider 596 and the inner bottom end surface of the third vertical groove 595. This design enables the lifting plate 591 and the stop block 594 to exert an upward thrust when they are subjected to pressure, and this thrust can assist the lifting plate 591 and the stop block 594 in resetting.

[0070] Furthermore, when the moving wheel 48 moves at the horizontal end surface 55, there is still a gap between the upper surface of the docking plate 6 and the upper surface of the second fixed plate 51. This design prevents the upper surface of the docking plate 6 from protruding from the top of the second fixed plate 51. At the same time, when the moving wheel 48 moves to the middle of the horizontal end surface 55, the upper surface of its connecting plate 4 can just protrude from the upper surface of the second fixed plate 51. This design allows the connecting plate 4 to move to the middle position of the bracket 21, just enough to allow the hooking groove 41 at the connecting plate 4 to leak out, which is convenient for hooking the pull rope 12. Finally, the first middle groove 54 and the second middle groove 57 are arranged relative to each other. This design prevents the limit strip 45 at the connecting plate 4 and the pressure rod 61 at the docking plate 6 from being interfered with when they are active, so that they can move accurately in the horizontal groove.

[0071] like Figures 1 to 8As shown, corresponding solar power components 7 can also be set on the upper surface of the monitoring pier body 1 and the bracket 21. The solar power components 7 include: a support column, a battery and a photovoltaic panel, wherein the support column can be set on the bracket 21 or the monitoring pier body 1, the battery is set on one side of the support column, the photovoltaic panel is set on the support column, and the motor 34 and the angle sensor 14 are electrically connected to the battery. This design allows the solar power component 7 to power the motor 34 and the angle sensor 14. In addition, it should be pointed out that the power supply mode and connection method of the battery and the photovoltaic panel belong to existing mature technologies and are not the core innovation content of the present invention, so they will not be described in detail here.

[0072] The specific use process of the present invention is:

[0073] First, the two monitoring pier bodies 1 are prefabricated or directly cast on site at a suitable distance, for example, within 10 meters or 15 meters, and are buried on both sides of the landslide crack to be monitored. Then, the fixing seat 2 and the bracket 21 are buried in the middle of the two monitoring pier bodies 1. Then, the pull rope 12 at the two monitoring pier bodies 1 is passed horizontally from the upper inner wall of the bracket 21 and the hook groove 41 at the connecting plate 4. After passing through, the pull rope 12 is adjusted to a suitable tension state (to ensure that the pull rope 12 can rebound quickly after being pulled, and to avoid the pull rope 12 being torn off).

[0074] When the pull rope 12 is disturbed by the outside world, the weight will compress the pull rope 12. During the compression process, the pull rope 12 will play a dragging role, so that the two ends of the pull rope 12 can pull the constant force springs 13 at the two monitoring piers. After pulling, the angle sensor 14 can sense the displacement value, and then the value is transmitted to the external monitoring station. According to the data, the user starts the motor 34 for forward and reverse operation.

[0075] When the motor 34 rotates, the screw rod 33 can drive the threaded block 35 to reciprocate back and forth, so that the threaded block 35 can drive the connecting seat 37 and the connecting plate 4 to move together. Since the upper surface of the connecting plate 4 is provided with a hook groove 41, the hook groove 41 can pull the pull rope 12 to move it from the middle of the bracket 21 to the edge position. In this process, due to the provision of the horizontal end surface 55, the inclined end surface 56 and the lifting assembly, when the connecting plate 4 and the docking plate 6 move to the side of the fixed plate through the moving wheel 48, the lifting assembly can be pressed downward first, and then it is pressed. The hooked pull rope 12 can be removed from the block 594, and then the connecting plate 4 drives the pull rope 12 to move to the edge position of the bracket 21. At this time, the moving wheel 48 is just at the inclined end surface 56. Since the inclined end surface 56 has a drop between the horizontal end surface 55 and the horizontal end surface 55, the connecting plate 4 and the docking plate 6 can be driven to move downward. While moving downward, the hooking groove 41 can release the hooked pull rope 12, and after releasing it, the pull rope 12 can rebound. After rebounding, due to the upward reset of the block 594, the rebounded pull rope 12 can be resisted, so that the pull rope 12 can be stored with energy after being resisted.

[0076] At the same time, due to the setting relationship between the connecting plate 4 and the connecting seat 37, the limit bar 45 in the opening can be moved and extended into the second transverse groove 53, so that the connecting plate 4 can be locked after entering, thereby preventing the connecting plate 4 and the docking plate 6 from moving upward. When the motor 34 reverses, the moving wheel 48 can be moved from the inclined end surface 56 to the horizontal end surface 55. At this time, the pressure rod 61 of the docking plate 6 can press the second pressure block 593 at the lifting assembly, so that after pressing, the lifting plate 591 and the stop block 594 can be driven to move downward, so that the energy-stored pull rope 12 can be released. After release, the pull rope 12 can rebound quickly, and the rebound effect can be used to shake off debris at the pull rope 12.

[0077] Finally, when the limiting bar 45 enters the first intermediate groove 54 from the second transverse groove 53, it automatically resets due to the lack of obstruction, allowing the upper end of the connecting plate 4 to re-engage the released pull rope 12. That is, as the connecting plate 4 continues to move toward the first intermediate groove 54, its lifting assembly first releases the stored energy of the pull rope 12. Due to the rapid rebound force of the pull rope 12, it can exceed the moving speed of the connecting plate 4 and reach the middle position in the bracket 21. When the connecting plate 4 that arrives later moves to the first intermediate groove 54, it can drive the hooking groove 41 to move upward and hook the pull rope 12, thereby dragging the pull rope 12 in the other direction.

[0078] After the above process, most of the debris at the pull rope 12 can be cleaned up, and the connecting plate 4 can be returned to the middle position of the bracket 21 after cleaning, so that the pulling of the pull rope 12 can be stopped. At this time, under the rebound effect of the constant force spring 13 and the pull rope 12, it can return to the initial state, and the angle sensor 14 can re-record these data and upload them to the background for comparison. If the monitoring data is within the normal range, it means that the debris at the pull rope 12 has been cleaned up and there is no crack change, so there is no need to go there immediately, thereby reducing the pressure on the monitor; if the change value of the monitoring data of the pull rope 12 continues after it is cleaned and returned to its place, it means that a crack has occurred, and in this case, the monitor needs to go to the scene to investigate.
