Description

Technical Field

[0001] This utility model relates to the field of slope detection technology, and in particular to a prism device for slope deformation monitoring. Background Technology

[0002] Deformation monitoring plays an increasingly important role in modern society as an engineering technology. It is necessary to analyze and evaluate the safety status of buildings, verify the rationality of building design, and provide feedback on the design and construction quality of buildings. It monitors the deformation of natural slopes, artificial slopes, open-pit mine slopes, foundation pit slopes, etc., so as to analyze the stability of the slope, provide timely warnings of landslides, monitor crustal tectonic movements, and thus analyze the development and evolution of the earth's crust and predict earthquakes.

[0003] Common prism devices for slope deformation monitoring only include the monitoring function, which can monitor the deformation of the slope, but lack the function of position extension. This makes it impossible to guarantee the accuracy of the monitoring position. Due to uncontrollable factors such as terrain, the device may not be able to be placed at the designated monitoring position, which will cause the detection position to deviate and affect the monitoring accuracy.

[0004] Therefore, in response to the problem that the prism device for slope deformation monitoring lacks a spatial positioning and extension adjustment mechanism, and the actual installation position of the prism is prone to deviate from the preset coordinates, resulting in monitoring point offset and data error, which affects the accuracy of deformation analysis, there is an urgent need to design a new type of prism device for slope deformation monitoring. Utility Model Content

[0005] To overcome the common problem that prism devices used for slope deformation monitoring lack spatial positioning and extension adjustment mechanisms, the actual installation position of the prism is prone to deviating from the preset coordinates, resulting in monitoring point offset and data errors, which affects the accuracy of deformation analysis.

[0006] The technical solution of this utility model is as follows: a prism device for slope deformation monitoring, comprising a support column, a support platform, a drive groove, a sliding groove, a motor, a sliding block, a short lead screw, a locking groove, a movable groove, a connecting shaft, an expansion plate, an extension groove, a long lead screw, and a locking block. The top of the support column is rotatably connected to the support platform. A drive groove is formed on the rear side of the middle of the top of the support platform. A sliding groove is formed on the front side of the middle of the top of the support platform. A motor is installed on the front side inside the drive groove. The output end of the motor passes through the support platform and is connected to a short lead screw. The short lead screw is located inside the sliding groove. A locking groove is formed at the front end of the short lead screw. A sliding block is installed inside the sliding groove corresponding to the position of the short lead screw. A movable groove is formed on the middle of the front side of the support platform corresponding to the position of the sliding groove. A connecting shaft is installed inside the movable groove. An expansion plate is formed on the middle of the front side of the support platform corresponding to the position of the movable groove. The rear end of the expansion plate is inserted into the movable groove. An extension groove is formed on the top of the expansion plate corresponding to the position of the sliding groove. A long lead screw is installed inside the extension groove corresponding to the position of the short lead screw. A locking block is installed at the rear end of the long lead screw corresponding to the position of the locking groove.

[0007] Preferably, the short lead screw is driven to rotate by a motor. The short lead screw is rigidly connected to the locking groove by a locking block, which drives the long lead screw to rotate. At the same time, the short lead screw drives the main unit to move towards the extension plate through a sliding block until the sliding block slides from the inside of the sliding groove to the connection point between the short lead screw and the long lead screw. At this point, the long lead screw drives the sliding block to continue sliding into the extension groove. After the sliding block enters the extension groove, it synchronously drives the main unit to move from the top of the support platform to the top of the extension plate until the main unit reaches the designated position and then the motor stops running, thus realizing the position extension function.

[0008] Preferably, the sliding block is threadedly connected to the short lead screw, the top of the sliding block is equipped with the main unit, and the rear end of the expansion plate is rotatably connected to the connecting shaft.

[0009] Preferably, the front end of the long lead screw is rotatably connected to the front side inside the extension groove, and the locking block at the rear end of the long lead screw is engaged in the locking groove at the front end of the short lead screw.

[0010] Preferably, a connecting ring is fitted around the top of the support column, and three support legs are connected to the connecting ring at equal intervals around its circumference.

[0011] Preferably, two connecting plates are symmetrically arranged at the left and right ends of the front side of the bottom of the support platform, and an installation plate is provided at the bottom of the connecting plates.

[0012] Preferably, a side plate is provided on the top of the connecting plate away from the expansion plate, and a telescopic rod is provided at the center of the side plate near the expansion plate, with a limit block connected to the end of the telescopic rod away from the side plate.

[0013] Preferably, the telescopic rod is fitted with springs all around it, with one end of the spring welded to the side plate and the other end of the spring welded to the limiting block, and a handle is provided at the bottom of the limiting block.

[0014] The beneficial effects of this utility model are:

[0015] 1. The short lead screw is driven by a motor to rotate, and the engaging block and engaging groove drive the long lead screw to rotate. The short lead screw pushes the main unit to the extension plate along the sliding groove via the sliding block. After the sliding block reaches the connection point, the long lead screw continues to move along the extension groove, pulling the main unit from the support platform to the top of the extension plate and stopping. This completes the spatial pose extension and adjustment function of the monitoring component. This structure is particularly suitable for deformation monitoring in complex scenarios such as slopes, highways, and mines. Its expandability and stability design solves the problem of monitoring blind spots caused by terrain limitations in traditional devices. At the same time, the mechatronics control improves the data acquisition efficiency and reliability. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please see Figures 1-8 This utility model provides an embodiment of a prism device for slope deformation monitoring, comprising a support column 1, a support platform 2, a drive groove 3, a sliding groove 4, a motor 5, a sliding block 6, a short lead screw 7, a snap-fit ​​groove 8, a movable groove 9, a connecting shaft 10, an extension plate 11, an extension groove 12, a long lead screw 13, and a snap-fit ​​block 14. The support platform 2 is rotatably connected to the top of the support column 1. The drive groove 3 is located on the rear side of the top center of the support platform 2. The sliding groove 4 is located on the front side of the top center of the support platform 2. The motor 5 is located inside the front side of the drive groove 3. The output end of the motor 5 passes through the support platform 2 and is connected to the short lead screw 7. The short lead screw 7 is located inside the sliding groove 4. The snap-fit ​​groove 8 is located at the front end of the short lead screw 7. The sliding block 6 is located inside the sliding groove 4 corresponding to the position of the short lead screw 7. The movable groove 9 is located on the middle front side of the support platform 2 corresponding to the position of the sliding groove 4. The connecting shaft 10 is located inside the movable groove 9. The extension plate 11 is located on the middle front side of the support platform 2 corresponding to the position of the movable groove 9. The rear end of the extension plate 11 is inserted into the movable groove 14. Inside the groove 9, an extension groove 12 is provided on the top of the extension plate 11 corresponding to the sliding groove 4. Inside the extension groove 12, a long lead screw 13 is provided corresponding to the short lead screw 7. A locking block 14 is provided at the rear end of the long lead screw 13 corresponding to the locking groove 8. The short lead screw 7 is driven to rotate around the axis by the starting motor 5. The rigid engagement of the locking block 14 and the locking groove 8 realizes the synchronous transmission of torque between the short lead screw 7 and the long lead screw 13. The long lead screw 13 rotates around the axis accordingly. The helical transmission surface of the short lead screw 7 and the sliding block The threaded engagement of the sliding block 6 drives the main unit 15 to linearly move along the sliding groove 4 toward the extension plate 11. When the sliding block 6 moves to the critical point of the threaded connection between the short lead screw 7 and the long lead screw 13, the long lead screw 13 drives the sliding block 6 to slide axially along the extension groove 12 through the continuous meshing of the external thread. Simultaneously, the main unit 15 is pulled to move across the initial mounting surface of the support platform 2 to the target working surface of the extension plate 11. After the main unit 15 reaches the preset positioning point, the motor 5 is de-energized, thus completing the spatial posture extension function of the monitoring device.

[0027] Please see Figures 2-8In this embodiment, the sliding block 6 is threadedly connected to the short lead screw 7. The top of the sliding block 6 is provided with a host 15. The rear end of the extension plate 11 is rotatably connected to the connecting shaft 10. The spiral groove of the short lead screw 7 and the dynamic engagement structure of the sliding block 6 drive the host 15 to translate along the sliding groove 4 towards the extension plate 11. The front end of the long lead screw 13 is rotatably connected to the front side inside the extension groove 12. The snap-fit ​​block 14 at the rear end of the long lead screw 13 is snapped into the snap-fit ​​groove 8 at the front end of the short lead screw 7. When the sliding block 6 is displaced to the threaded connection point between the short lead screw 7 and the long lead screw 13, the long lead screw 13 continues to drive the sliding block 6 to move axially along the extension groove 12 through the engagement of its external thread with the internal thread of the sliding block 6. A connecting ring 16 is fitted on the upper part of the support column 1. Three support legs 17 are rotatably connected at equal intervals around the connecting ring 16, and the support column 1 is supported by the three support legs 17.

[0028] Please see Figures 1-8 In this embodiment, two connecting plates 18 are symmetrically arranged at the left and right ends of the bottom front side of the support platform 2. A mounting plate 19 is provided at the bottom of the connecting plate 18. The mounting plate 19 is welded to the support platform 2 through the connecting plate 18. A side plate 20 is provided on the top side of the connecting plate 18 away from the expansion plate 11. A telescopic rod 21 is provided at the center of the side plate 20 near the expansion plate 11. A limit block 22 is connected to the end of the telescopic rod 21 away from the side plate 20. The movement trajectory of the limit block 22 is limited by the telescopic rod 21. A spring 23 is fitted around the telescopic rod 21. One end of the spring 23 is welded to the side plate 20, and the other end of the spring 23 is welded to the limit block 22. A handle 24 is provided at the bottom of the limit block 22. The limit block 22 is pushed towards the bottom of the expansion plate 11 by the thrust of the spring 23 until a part of the limit block 22 is located at the bottom of the expansion plate 11. The expansion plate 11 is supported by the combination of the two limit blocks 22.

[0029] During operation, if the actual monitoring environment prevents the device from reaching the designated location, first place the device near the detection point. Then, simultaneously pull the two limiting blocks 22 to the left and right using both handles 24, causing them to move away from each other. At this time, the spring 23 and the telescopic rod 21 are compressed and retract. Then, lift the end of the extension plate 11 away from the connecting shaft 10 upwards. The end of the extension plate 11 near the connecting shaft 10 then rotates around the connecting shaft 10 until the extension plate 11 is horizontal. At this point, release the two handles 24, and the spring 23 pushes the limiting blocks 22 towards the bottom of the extension plate 11 until a portion of the limiting blocks 22 is at the bottom of the extension plate 11. The combination of 22 supports the expansion plate 11. When the short lead screw 7 is driven to rotate by the motor 5, the short lead screw 7 transmits torque through the rigid engagement of the snap-fit ​​block 14 and the snap-fit ​​groove 8, and simultaneously drives the long lead screw 13 to rotate around the axis. At the same time, the dynamic engagement structure between the helical groove of the short lead screw 7 and the sliding block 6 drives the main unit 15 to translate along the sliding groove 4 towards the expansion plate 11. When the sliding block 6 is displaced to the threaded connection point between the short lead screw 7 and the long lead screw 13, the long lead screw 13 continues to drive the sliding block 6 to move axially along the extension groove 12 through the engagement of its external thread and the internal thread of the sliding block 6. Simultaneously, the main unit 15 is pulled from the initial position of the support platform 2 to the expansion position of the expansion plate 11 until the main unit 15 reaches the preset coordinate and then the motor 5 is stopped and locked, thus realizing the function of position extension.

[0030] Through the above steps, the short lead screw 7 is driven to rotate by the motor 5. The locking block 14 and the locking groove 8 are rigidly engaged, driving the long lead screw 13 to rotate synchronously. The short lead screw 7 pushes the main unit 15 to move towards the extension plate 11 through the sliding block 6 along the sliding groove 4. When the sliding block 6 reaches the connection point between the short lead screw 7 and the long lead screw 13, the long lead screw 13 drives the sliding block 6 to continue moving along the extension groove 12. The main unit 15 is then moved from the support platform 2 to the top of the extension plate 11 and then stops, realizing the function of extending the monitoring position. This solves the problem that common prism devices for slope deformation monitoring only have the function of monitoring and can monitor the deformation of the slope, but lack the function of extending the position. This makes it impossible to guarantee the accuracy of the monitoring position. It is easy for the device to be unable to be placed in the designated monitoring position due to uncontrollable factors such as terrain. This causes the detection position to deviate and affects the monitoring accuracy.
