Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of slope monitoring, and more particularly to a dynamic monitoring device and method for a large-slope curved surface slope. Background Art
[0002] In the field of modern engineering construction, steep curved slopes, as a special geological structure, are widely found in scenarios such as mountain road and railway construction, open-pit mining, water conservancy and hydropower projects, and urban slope management. Due to their steep slopes and complex curved surface shapes, these slopes are always unstable under the dual influence of the natural environment and human engineering activities, making them extremely prone to geological disasters such as landslides and collapses.
[0003] After searching, a Chinese patent with announcement number CN214471029U discloses a device for monitoring slope support stress and deformation. This utility model sets up an anchor stress gauge, an inclination measuring device and an observation device, so that the monitoring and measurement of the entire device can be carried out simultaneously, thereby solving the problem of incomplete correspondence between the data on slope support stress changes and the data measured at the displacement position of slope deformation monitoring.
[0004] When the above-mentioned monitoring device is in use, the displacement change of the slope is observed at close range through a prism, the anchor stress meter measures the change in the support stress of the slope under the displacement change, and the inclination measuring device measures the angle change of the slope. However, the close-range prism observation requires manual visits to the site to read the data regularly, and it is impossible to grasp the displacement change of the slope in real time. At the same time, it is not convenient to issue a timely alarm for the slope dynamics. Once the slope has abnormal displacement during the non-observation period, it is easy to miss the best warning opportunity. Summary of the Invention
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a dynamic monitoring device and a monitoring method for a large-slope curved surface slope, aiming to solve the problems raised in the above-mentioned background technology.
[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a dynamic monitoring device for a large-slope curved surface slope, comprising a mounting frame, an extrusion frame and a fixed frame, the extrusion frame and the fixed frame being both located on one side of the mounting frame, and one end of the extrusion frame extending into the interior of the fixed frame, a controller and an alarm being fixedly installed on one side of the interior of the mounting frame, and the controller being located on the top of the alarm, a hydraulic cylinder being fixedly connected to one side of the interior of the fixed frame, a circular plate being fixedly connected to one end of the hydraulic cylinder, a control switch being fixedly connected to the other side of the circular plate, a pressure plate being movably provided on the other side of the control switch, and the other side of the pressure plate being threadedly connected to the extrusion frame, side plates being fixedly connected on both front and rear sides of the pressure plate, sliding rods being movably provided on both side plates, and both ends of the two sliding rods being fixedly connected to the fixed frame, and the controller being electrically connected to the control switch and the alarm, respectively.
[0007] Furthermore, springs are movably provided on the two sliding rods, and two ends of the two springs are fixedly connected to the fixed frame and the two side plates respectively.
[0008] It can be seen that in the above technical solution, when the extrusion frame is away from the slope, the two springs rebound and drive the pressure plate to reset.
[0009] Furthermore, a second adjustment component is provided on the mounting frame, and the second adjustment component includes a stepping motor, a second screw rod, a moving frame and a connecting frame.
[0010] Furthermore, the stepper motor is fixedly mounted inside the mounting frame, and the output shaft end of the stepper motor is fixedly connected to the second screw rod, one end of the second screw rod is movably connected to the mounting frame through a bearing, and the outer side of the second screw rod is threadedly connected to the movable frame, one side of the movable frame passes through the mounting frame and is fixedly connected to the connecting frame, a limit plate is movably provided inside the movable frame, and the limit plate is fixedly mounted on the other end of the second screw rod.
[0011] Furthermore, a first adjustment component is provided on the connecting frame, and the first adjustment component includes a sliding frame, a first screw rod, two threaded sleeves, a self-locking motor and two rotating shafts, and the top and bottom ends of the first screw rod are fixedly connected to the connecting frame.
[0012] Furthermore, the sliding frame is movably sleeved on the first screw rod, the two threaded sleeves are movably sleeved on the first screw rod, and the opposite sides of the two threaded sleeves are in contact with the sliding frame.
[0013] Furthermore, the self-locking motor is fixedly mounted on the front side of the sliding frame, and the output shaft end of the self-locking motor is fixedly connected to one of the rotating shafts, the two facing ends of the rotating shafts are fixedly connected to the fixed frame, and the two opposite ends of the rotating shafts are movably connected to the sliding frame through bearings.
[0014] Furthermore, a push handle is fixedly connected to the center position of the other side of the mounting frame, and universal wheels are fixedly connected to the bottom end of the mounting frame near the four corners.
[0015] It can be seen that in the above technical solution, the push handle is pushed to make the four universal wheels slide on the ground, thereby driving the mounting frame to move horizontally.
[0016] Furthermore, a threaded vertical rod is threadedly connected at the center position of the bottom end of the mounting frame, and an insert is fixedly connected to the bottom end of the threaded vertical rod.
[0017] It can be seen that in the above technical solution, the threaded vertical rod is rotated and the insert block is extended into the ground, so that the mounting frame can be limited.
[0018] A method for dynamic monitoring of a steep curved surface slope is provided for constructing the aforementioned device for dynamic monitoring of a steep curved surface slope, and specifically comprises the following steps: S1. Movement and preliminary positioning of the mounting frame: Push the handle and move the mounting frame to the slope monitoring area via the universal wheels. Initially align the extrusion frame with the protruding or easily displaced key parts of the slope surface. Visually adjust the horizontal distance between the mounting frame and the slope until the front end of the extrusion frame is 5-10 cm away from the slope surface.
[0019] S2. Fix and level the mounting bracket: Turn the threaded rod clockwise to screw the insert vertically into the ground until the universal wheel at the bottom of the mounting bracket is off the ground and the device does not shake.

Complete the base fixation.
[0020] S3. Fine-tune the horizontal position of the extrusion frame: Start the stepper motor of the second adjustment component, and use it to drive the second screw to rotate, driving the movable frame and the connecting frame to move horizontally, so that the front end of the extrusion frame slowly approaches the slope surface until the extrusion frame surface is initially fitted with the raised part of the slope. Record the number of pulses of the stepper motor at this time as the initial position parameter.
[0021] S4. Adjust the vertical height and angle of the extrusion frame: Rotate the threaded sleeve of the first adjustment component to move it away from the first screw, release the lock of the sliding frame, manually move the sliding frame up and down, adjust the vertical height of the extrusion frame to the center of the target monitoring area, tighten the threaded sleeve again to fix it, start the self-locking motor to drive the shaft to rotate, drive the fixed frame and the extrusion frame to rotate, and monitor the inclination angle of the extrusion frame through the laser goniometer to ensure that the angle between it and the normal of the slope surface is ≤5° to achieve a close fit.
[0022] S5. Monitoring threshold setting and real-time monitoring: Start the hydraulic cylinder, extend the piston rod to drive the control switch to move horizontally, adjust the initial distance between the pressure plate and the control switch to 2-5cm, press the "Start" button on the controller, and the device enters the monitoring state. When the slope moves, the extrusion frame moves and compresses the spring, causing the pressure plate to touch the control switch. The alarm will immediately sound an on-site alarm. At the same time, the controller sends a displacement limit signal to the mobile phone through the wireless module. The staff can remotely adjust the hydraulic cylinder stroke to update the monitoring threshold.
[0023] Technical effects and advantages of the present invention: 1. In the present invention, when the slope moves, the extrusion frame starts to move horizontally, thereby driving the pressure plate to move horizontally. When the pressure plate squeezes the control switch, the alarm sounds, and the controller transmits the signal to the mobile phone. The piston rod on the hydraulic cylinder extends to drive the circular plate and the control switch to move horizontally. The distance between the pressure plate and the control switch can be adjusted according to needs. The operation is simple and convenient for timely alarm of slope dynamics. 2. The present invention drives the second screw to rotate by the stepping motor, and the second screw can drive the movable frame to move horizontally, thereby driving the connecting frame to move horizontally, and further driving the first adjustment component and the extrusion frame to move horizontally, so that the position of the extrusion frame can be adjusted according to needs. The structure is simple and easy to use; 3. The present invention rotates the threaded sleeve and moves it away from the first screw rod, thereby releasing the fixation between the sliding frame and the first screw rod, and vertically moving the sliding frame, thereby driving the extrusion frame to move vertically.

[0027] The following describes the implementation of the present invention using specific embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. Obviously, the embodiments described are only a portion of the present invention, not all of it. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are intended to fall within the scope of protection of the present invention.
[0028] Refer to the instruction manual Figure 1-6 , a dynamic monitoring device for a large-slope curved surface slope of this embodiment includes a mounting frame 1, an extrusion frame 2 and a fixed frame 3.

[0029] Furthermore, springs 18 are movably provided on the two slide bars 17 , and two ends of the two springs 18 are fixedly connected to the fixed frame 3 and the two side plates 16 respectively.
[0030] Furthermore, a second adjustment component 5 is provided on the mounting frame 1, and the second adjustment component 5 includes a stepper motor 501, a second screw rod 502, a movable frame 503 and a connecting frame 504. The stepper motor 501 is fixedly mounted inside the mounting frame 1, and the output shaft end of the stepper motor 501 is fixedly connected to the second screw rod 502. One end of the second screw rod 502 is movably connected to the mounting frame 1 through a bearing, and the outer side of the second screw rod 502 is threadedly connected to the movable frame 503. One side of the movable frame 503 passes through the mounting frame 1 and is fixedly connected to the connecting frame 504. A limit plate 505 is movably provided inside the movable frame 503, and the limit plate 505 is fixedly mounted on the other end of the second screw rod 502.
[0031] Among them, the stepper motor 501 is started, and the stepper motor 501 drives the second screw rod 502 to rotate. Since the second screw rod 502 is threadedly connected to the movable frame 503, the mounting frame 1 limits the rotation of the movable frame 503, so the second screw rod 502 can drive the movable frame 503 to move horizontally, thereby driving the connecting frame 504 to move horizontally, and then driving the first adjustment component 4 and the extrusion frame 2 to move horizontally. The position of the extrusion frame 2 is adjusted according to needs. The structure is simple and easy to use. At the same time, the limit plate 505 can limit the moving range of the movable frame 503 to prevent the movable frame 503 from moving away from the second screw rod 502.
[0032] Furthermore, a first adjusting component 4 is provided on the connecting frame 504, and the first adjusting component 4 includes a sliding frame 401, a first screw rod 402, two threaded sleeves 403, a self-locking motor 404 and two rotating shafts 405. The top and bottom ends of the first screw rod 402 are fixedly connected to the connecting frame 504, the sliding frame 401 is movably sleeved on the first screw rod 402, the two threaded sleeves 403 are movably sleeved on the first screw rod 402, and the facing sides of the two threaded sleeves 403 are in contact with the sliding frame 401, the self-locking motor 404 is fixedly installed on the front side of the sliding frame 401, and the output shaft end of the self-locking motor 404 is fixedly connected to one of the rotating shafts 405, the facing ends of the two rotating shafts 405 are fixedly connected to the fixed frame 3, and the opposite ends of the two rotating shafts 405 are movably connected to the sliding frame 401 through bearings.
[0033] Among them, the threaded sleeve 403 is rotated and moved away from the first screw rod 402, thereby releasing the fixation between the sliding frame 401 and the first screw rod 402, and the sliding frame 401 is moved vertically, thereby driving the extrusion frame 2 to move vertically, and adjusting the height of the extrusion frame 2 as needed. Similarly, the sliding frame 401 is squeezed and fixed by the two threaded sleeves 403, and the self-locking motor 404 is started. The self-locking motor 404 drives the two rotating shafts 405 and the fixed frame 3 to rotate, thereby driving the extrusion frame 2 to rotate, and adjusting the angle of the extrusion frame 2 as needed to make the extrusion frame 2 fully fit the slope. The operation is simple and the application range is wide.
[0034] Furthermore, a push handle 8 is fixedly connected to the center position of the other side of the mounting frame 1, and universal wheels 10 are fixedly connected to the bottom end of the mounting frame 1 near the four corners. A threaded vertical rod 9 is threadedly connected to the center position of the bottom end of the mounting frame 1, and an insert 11 is fixedly connected to the bottom end of the threaded vertical rod 9.
[0035] Refer to the instruction manual Figure 7 A method for dynamically monitoring a large-slope curved surface slope in this embodiment is used to construct the aforementioned dynamic monitoring device for a large-slope curved surface slope, and specifically comprises the following steps: S1. Movement and preliminary positioning of the mounting frame: Push the handle 8 and move the mounting frame 1 to the slope monitoring area via the universal wheel 10. Initially align the extrusion frame 2 with the protruding or easily displaced key parts of the slope surface. Visually adjust the horizontal distance between the mounting frame 1 and the slope until the front end of the extrusion frame 2 is 5-10 cm away from the slope surface.
[0036] S2. Fix and level the mounting frame: Turn the threaded upright 9 clockwise to screw the insert 11 vertically into the ground until the universal wheel 10 at the bottom of the mounting frame 1 is off the ground and the device does not shake. Use a spirit level to check the horizontality of the top surface of the mounting frame 1. Fine-tune the height of the threaded upright 9 to ensure that the horizontal error is ≤1°. Complete the base fixation.
[0037] S3. Fine-tune the horizontal position of the extrusion frame: Start the stepper motor 501 of the second adjustment component 5, and drive the second screw rod 502 to rotate, thereby driving the movable frame 503 and the connecting frame 504 to move horizontally, so that the front end of the extrusion frame 2 slowly approaches the slope surface until the curved surface of the extrusion frame 2 is initially in contact with the raised part of the slope. Record the number of pulses of the stepper motor 501 at this time as the initial position parameter.
[0038] S4. Adjust the vertical height and angle of the extrusion frame: rotate the threaded sleeve 403 of the first adjustment component 4 to move it away from the first screw 402, release the lock of the sliding frame 401, manually move the sliding frame 401 up and down, adjust the vertical height of the extrusion frame 2 to the center of the target monitoring area, tighten the threaded sleeve 403 again to fix it, start the self-locking motor 404 to drive the rotating shaft 405 to rotate, and drive the fixed frame 3 and the extrusion frame 2 to rotate. Monitor the inclination angle of the extrusion frame 2 through the laser goniometer to ensure that the angle between it and the normal of the slope surface is ≤5° to achieve a close fit.
[0039] S5. Setting monitoring threshold and real-time monitoring: Start the hydraulic cylinder 12, and drive the control switch 14 to move horizontally by extending the piston rod. Adjust the initial distance between the pressure plate 15 and the control switch 14 to 2-5 cm, and press the "start" button of the controller 6. The device enters the monitoring state. When the slope moves, the extrusion frame 2 is pushed to move and the spring 18 is compressed, so that the pressure plate 15 touches the control switch 14, the alarm 7 immediately alarms on site. At the same time, the controller 6 sends a displacement limit signal to the mobile phone through the wireless module. The staff can remotely adjust the stroke of the hydraulic cylinder 12 to update the monitoring threshold.
[0040] The method of using this embodiment is: When in use, the corresponding extrusion frame 2 is selected according to the slope of the slope, and then one end of the extrusion frame 2 is inserted into the pressure plate 15. The staff pushes the push handle 8 and makes the four universal wheels 10 slide on the ground, thereby driving the mounting frame 1 to move horizontally. When the mounting frame 1 moves to the slope, and the other side of the extrusion frame 2 fits the curved surface of the slope, the threaded vertical rod 9 is rotated and the plug 11 is extended into the ground, so that the mounting frame 1 can be limited. When the slope moves, the extrusion frame 2 starts to move horizontally, thereby driving the pressure plate 15 to move horizontally. At the same time, the pressure plate 15 drives the two side plates 16 to move on the two sliding rods respectively. 17 slides on the pressure plate 15, thereby preventing the horizontal movement of the pressure plate 15 from deflecting, and the two side plates 16 can squeeze the two springs 18. When the pressure plate 15 squeezes the control switch 14, the alarm 7 sounds an alarm, and the controller 6 transmits the signal to the mobile phone to start the hydraulic cylinder 12. The piston rod on the hydraulic cylinder 12 extends to drive the circular plate 13 and the control switch 14 to move horizontally. The distance between the pressure plate 15 and the control switch 14 is adjusted according to demand. The operation is simple and convenient for timely alarm of the slope dynamics. When the extrusion frame 2 is away from the slope, the two springs 18 rebound to drive the pressure plate 15 to reset.
[0041] It is worth noting that when the control switch 14 is squeezed, the alarm program will be triggered immediately, and the alarm 7 will then emit a loud alarm sound to alert the surrounding personnel to the abnormality of the slope. At the same time, the control switch 14 will transmit the trigger signal to the controller 6. After the controller 6 analyzes and processes the signal, it will transmit the alarm signal in real time to the mobile phone of the relevant staff through a pre-set wireless communication protocol (such as 4G, 5G, NB-IoT, etc.), ensuring that the staff can obtain slope abnormality information in the first time no matter where they are. Staff can send adjustment instructions to the controller 6 via a mobile phone app. After receiving the instructions, the controller 6 sends a drive signal to the hydraulic cylinder 12 according to the preset control logic. After the hydraulic cylinder 12 receives the signal, its internal hydraulic system starts to work, and the piston rod extends or shortens according to the instructions, thereby driving the circular plate 13 and the control switch 14 to move horizontally, achieving precise adjustment of the distance between the pressure plate 15 and the control switch 14. For example, when the slope is in a relatively stable stage, the distance between the two can be appropriately increased to improve monitoring sensitivity; when the surrounding environment of the slope is complex and there are many interference factors, the distance can be reduced to avoid false alarms. The entire adjustment process is convenient to operate, does not require manual on-site intervention, and can effectively monitor and control the slope dynamics in a timely and flexible manner.

S3, fine adjustment of the horizontal position of the extrusion frame: start the stepper motor (501) of the second adjustment component (5), and drive the second screw rod (502) to rotate, thereby driving the movable frame (503) and the connecting frame (504) to move horizontally, so that the front end of the extrusion frame (2) slowly approaches the slope surface until the curved surface of the extrusion frame (2) is initially fitted with the convex part of the slope, and record the pulse number of the stepper motor (501) at this time as the initial position parameter; S4, vertical height and angle adjustment of the extrusion frame: rotate the threaded sleeve (403) of the first adjustment component (4) to move it away from the first screw (402), release the lock of the sliding frame (401), manually move the sliding frame (401) up and down, adjust the vertical height of the extrusion frame (2) to the center of the target monitoring area, tighten the threaded sleeve (403) again to fix it, start the self-locking motor (404) to drive the rotating shaft (405) to rotate, drive the fixed frame (3) and the extrusion frame (2) to rotate, monitor the inclination angle of the extrusion frame (2) by the laser angle meter, and make the angle between it and the normal of the slope surface ≤5° to achieve a close fit; S5. Setting of monitoring threshold and real-time monitoring: Start the hydraulic cylinder (12), and drive the control switch (14) to move horizontally by extending the piston rod. Adjust the initial spacing between the pressure plate (15) and the control switch (14) to 2-5 cm. Press the "start" button of the controller (6), and the device enters the monitoring state. When the slope moves, the extrusion frame (2) moves and compresses the spring (18), so that the pressure plate (15) touches the control switch (14). The alarm (7) immediately sounds an on-site alarm. At the same time, the controller (6) sends a displacement limit signal to the mobile phone through the wireless module. The staff can remotely adjust the stroke of the hydraulic cylinder (12) to update the monitoring threshold.
