Description

Technical Field

[0001] The present invention belongs to the technical field of geotechnical engineering monitoring, and in particular relates to a geotechnical engineering slope deformation monitoring device. Background Art

[0002] At present, my country's topography is complex and diverse. In the process of engineering construction, complex and diverse slopes continue to emerge. The slope is a complex system project, and its stability directly affects whether the entire project can be carried out smoothly and the personal safety of the workers. In addition, after the completion of the project, the slope also poses certain safety hazards to passing pedestrians and vehicles, so it is also necessary to monitor the stability of the slope in real time. Since the instability and collapse of the slope does not occur in an instantaneous period, but is caused by the accumulation of multiple instability factors over a certain period of time, it develops from creep deformation to unstable sliding, so it is necessary to continuously monitor the deformation of the slope at each time period.

[0032] When an element is referred to as being “fixed to” or “disposed on” another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it can be directly connected to the other element or indirectly connected to the other element.

[0033] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] The embodiment of the present invention provides a geotechnical engineering slope deformation monitoring device, such as Figure 1-10 As shown, the geotechnical engineering slope deformation monitoring device includes: at least two monitoring devices distributed on the slope surface, which are connected to each other to form a triggerable monitoring array, wherein any one of the monitoring devices includes: an assembly plate 1 and an immersion cone 2 detachably mounted on the bottom of the assembly plate 1; an assembly block 3, fixedly mounted on the top of the assembly plate 1, the overall structure is rectangular, and mortise grooves 4 are provided on both sides, at least one of the mortise grooves 4 is clamped with a tenon clip 5 and detachably fixed with bolts; at least one deformation monitoring trigger sensor 6, provided below the corresponding tenon clip 5 and detachably connected to the assembly plate 1; at least one sliding trigger mechanism, provided on the corresponding side of at least one corresponding tenon clip 5 and the assembly block 3, and arranged corresponding to the corresponding deformation monitoring trigger sensor 6, for triggering the deformation monitoring trigger sensor 6 when the slope is deformed.

[0035] In this embodiment, when installing the equipment, the burying cone 2 is first installed, and the burying cone 2 is fixed at a predetermined position on the slope to ensure that the device is stably embedded in the soil. Then, the assembly plate 1 is fixed to the top of the burying cone 2 with bolts. The tongue and groove 4 on both sides of the assembly block 3 on the assembly plate 1 provides a basis for subsequent configuration.

[0036] Then configure the tenon clamping plate 5, and as needed, insert one or more tenon clamping plates 5 into the tenon groove 4 of the assembly block 3 and fix them detachably with bolts, then install the deformation monitoring trigger sensor 6 under the tenon clamping plate 5 and detachably connect it to the assembly plate 1.

[0037] The sliding trigger mechanism on the corresponding sides of the tenon clamping plate 5 and the assembly block 3 ensures that it is arranged correspondingly to the deformation monitoring trigger sensor 6 so that the sensor can be triggered when the slope deforms.

[0038] Multiple identical monitoring devices are connected to form a monitoring array. Multiple monitoring devices are distributed on the slope surface and connected to form a triggerable monitoring array to achieve comprehensive monitoring of the entire slope (such as Figure 10 shown).

[0039] When the slope deforms, the sliding trigger mechanism senses this change and triggers the corresponding deformation monitoring trigger sensor 6. The sensor converts the detected deformation data into an electrical signal and transmits it wirelessly or wired to the central monitoring system. The central monitoring system analyzes and processes the received data. If the detected deformation exceeds the preset threshold, the system will immediately issue an early warning, notifying relevant personnel to take necessary countermeasures.

[0040] The geotechnical engineering slope deformation monitoring device described in this patent is suitable for slope monitoring in various complex terrains, especially in areas with complex geological conditions and prone to landslides or other geological disasters.

[0041] This solution adopts a modular design. Each monitoring device is an independent module that can be installed and configured separately, which greatly improves the flexibility and convenience of installation.

[0042] Deformation monitoring trigger sensors can monitor slope deformation in real time and accurately record deformation data, providing strong support for early warning and response to geological disasters.

[0043] This solution is highly scalable. By connecting multiple monitoring devices to form a monitoring array, comprehensive monitoring of the entire slope can be achieved. The monitoring range can be flexibly expanded as needed, and the installation locations of multiple devices can be freely adjusted.

[0044] Once deformation data exceeding the preset threshold is detected, the system will immediately issue an early warning and notify relevant personnel to take necessary response measures, effectively avoiding the occurrence of geological disasters or reducing the losses caused by them.

[0045] In a further preferred embodiment of the present invention, the sliding trigger mechanism includes a sliding plate 7 that can be slidably installed on the tenon card plate 5, and the sliding plate 7 is vertically arranged to the deformation monitoring trigger sensor 6 below. The bottom of the sliding plate 7 is fixedly installed with an anti-slip trigger plate 8 for pressing to trigger the deformation monitoring trigger sensor 6, and the top of the sliding plate 7 is fixedly installed with an axle frame 9, and a tensioning guide roller 10 is rotatably installed on the axle frame 9. A head positioning sleeve 11 fixedly connected to the corresponding side of the assembly block 3 is provided above the tenon card plate 5, and a connecting belt 13 can be fixedly installed on the head positioning sleeve 11 with bolts. The connecting belt 13 can slide through the assembly plate 1 after passing over the top of the tensioning guide roller 10, and extend to the external slope to be fixed to another monitoring device to form a triggerable monitoring array.

[0046] In this embodiment, the present invention adopts the structure of a sliding trigger mechanism: the sliding trigger mechanism is mainly composed of a sliding plate 7, an anti-slip trigger plate 8, an axle frame 9, a tensioning guide roller 10, a head positioning sleeve 11 and a connecting belt 13. The sliding plate 7 can be slidably installed on the tenon clamping plate 5 and is vertically arranged with the deformation monitoring trigger sensor 6 below. The anti-slip trigger plate 8 is fixed to the bottom of the sliding plate 7 and is used to press and trigger the deformation monitoring trigger sensor 6 when the sliding plate 7 moves. The axle frame 9 is fixed to the top of the sliding plate 7, and the tensioning guide roller 10 is rotatably installed thereon. The head positioning sleeve 11 is fixedly connected to the corresponding side of the assembly block 3, and the connecting belt 13 can be fixedly installed thereon by bolts. After passing over the tensioning guide roller 10, the connecting belt 13 can slide through the assembly plate 1 and extend to the external slope to be fixed to another monitoring device. The multiple monitoring devices are interconnected to form a straight line or a curved line, forming a monitoring line. In this solution, the same structure can also be set around the assembly block 3 to form a monitoring network (not shown) to meet the use of various environments.

[0047] During use, ensure that the anti-slip trigger plate 8 is facing the deformation monitoring trigger sensor 6, install the connecting belt 13 on the head positioning sleeve 11, and make it pass over the top of the tensioning guide roller 10, and then pass through the reserved hole of the assembly plate 1 to extend to the external slope; distribute multiple monitoring devices on the slope, and fix the connecting belts 13 between adjacent monitoring devices to each other to form a triggerable monitoring array.

[0048] When the slope deforms, the displacement or stress changes in the slope surface can cause a monitoring device to move or a separate deformation of the connecting belt 13, which is positioned 5-15 cm above the ground. The tension in the connecting belt 13 is transmitted to the sliding trigger mechanism. The change in tension in the connecting belt 13 causes the tensioning roller 10 to move downward, driving the sliding plate 7 in the groove of the tenon-type clamping plate 5. As the sliding plate 7 slides, the anti-slip trigger plate 8 presses the deformation monitoring trigger sensor 6, triggering it to collect and transmit deformation data.

[0049] The sliding trigger mechanism described in this embodiment is applicable to various geological engineering environments that require real-time monitoring of slope deformation, especially those areas with complex geological conditions and prone to landslides or other geological disasters.

[0050] This sliding trigger mechanism is directly connected to the slope surface via a connecting strap 13, enabling real-time sensing of minute displacements or stress changes, enabling highly sensitive monitoring of slope deformation. The sliding plate 7 slides within the groove of the tenon-mounted clamping plate 5, ensuring the stability and reliability of the trigger mechanism. Furthermore, the anti-drop trigger plate 8 prevents it from falling off or misaligning during the triggering process.

[0051] In a further preferred embodiment of the present invention, a belt-through opening 12 for the connecting belt 13 to pass through is provided on the assembly plate 1, and the inner wall of the belt-through opening 12 is smooth.

[0052] In this embodiment, the belt insertion opening 12 is a specific opening located on the assembly plate 1, and its size and shape are carefully designed to ensure that the connecting belt 13 can smoothly pass through it. The inner wall of the belt insertion opening 12 is smooth to ensure the sliding sensitivity of the connecting belt 13.

[0053] During installation and use, the connecting belt 13 needs to pass over the tensioning guide roller 10 and through the belt insertion opening 12. Because the inner wall of the belt insertion opening 12 is smooth, the connecting belt 13 slides through easily without any additional pushing or pulling force. This greatly simplifies the installation process and improves the reliability and stability of the entire system.

[0054] When the slope deforms, the displacement or stress changes on the slope surface are transmitted to the sliding trigger mechanism through the connecting belt 13. The smooth inner wall of the connecting belt 13 reduces frictional resistance in the belt insertion opening 12, ensuring that the trigger mechanism can sensitively respond to slope deformation. Furthermore, the smooth inner wall helps reduce wear on the connecting belt 13, extending its service life.

[0055] This improvement is particularly suitable for geological engineering environments that require long-term, continuous monitoring of slope deformation. Under complex and changing geological conditions, slope deformation can be very subtle and difficult to detect, necessitating a highly sensitive and reliable monitoring device to capture these changes. The present invention's sliding trigger mechanism and smooth inner-walled belt insertion port 12 precisely meet this need.

[0056] In a further preferred embodiment of the present invention, a transverse sliding slot 14 is provided on the tenon clamping plate 5, and a guide thread column 15 is fixedly installed in the transverse sliding slot 14. An elastic metal sheet 16 can be slidably sleeved on the guide thread column 15, and a section of the elastic metal sheet 16 extends between the tenon clamping plate 5 and the shaft frame 9. This section is upwardly arched, and the arched part is in conflict with the bottom of the shaft frame 9, so as to support the sliding plate 7, the shaft frame 9 and the tensioning guide roller 10 to tighten the connecting belt 13. A sliding cylinder 17 is fixedly installed on one end of the elastic metal sheet 16 located above the tenon clamping plate 5, and the sliding cylinder 17 is in slidable contact with the top of the tenon clamping plate 5. A spring 18 is sleeved on the guide thread column 15 for contacting the elastic metal sheet 16. An adjusting nut 19 is threadedly sleeved on the guide thread column 15, and the adjusting nut 19 is in conflict with the other end of the spring 18.

[0057] In this embodiment, components such as a transverse slide 14, a guide thread column 15, an elastic metal sheet 16, a sliding cylinder 17, a spring 18 and an adjusting nut 19 are newly added to the tenon clamping plate 5. These components work together to achieve the tightening and fine-tuning of the connecting belt 13.

[0058] The transverse sliding slot 14 is located on the tenoned clamping plate 5, providing sliding space for the elastic metal sheet 16 and the sliding cylinder 17. The guide thread 15 is fixedly mounted within the transverse sliding slot 14, serving as a guide and support structure for the elastic metal sheet 16 and the adjusting nut 19. The elastic metal sheet 16 is sleeved on the guide thread 15 and can slide thereon. One end of the elastic metal sheet 16 extends between the tenoned clamping plate 5 and the shaft frame 9, forming an upwardly curved shape. The curved portion contacts the bottom of the shaft frame 9, thereby supporting the sliding plate 7, the shaft frame 9, and the tensioning guide roller 10, thereby tightening the connecting belt 13. The sliding cylinder 17 is fixedly mounted on the upper end of the elastic metal sheet 16, slidably contacting the top of the tenoned clamping plate 5, allowing the elastic metal sheet 16 to slide during adjustment. A spring 18 is sleeved on the guide thread 15, with one end contacting the elastic metal sheet 16 and the other end contacting the adjusting nut 19. Spring 18 provides an upward restoring force for the elastic metal sheet 16, ensuring that the connecting strap 13 remains tensioned. Adjusting nut 19 is threaded onto the guide thread post 15 and can be rotated to adjust its position on the guide thread post 15. By adjusting the position of nut 19, the compression of spring 18 can be fine-tuned, thereby fine-tuning the tension of the connecting strap 13.

[0059] During installation and use, first adjust the compression of spring 18 using adjustment nut 19, so that the arched portion of elastic metal sheet 16 exerts appropriate support on shaft bracket 9, thereby tightening connecting strap 13. As the slope deforms, the tension in connecting strap 13 changes. At this time, elastic metal sheet 16 slides on guide thread 15, deforming simultaneously. The elastic restoring force of spring 18 maintains the tension of connecting strap 13. To further adjust the tension of connecting strap 13, simply rotate adjustment nut 19.

[0060] When the slope deforms, the tension in the connecting strap 13 changes. If the tension decreases, the elastic metal sheet 16 moves upward under the elastic restoring force of spring 18, thereby increasing the support force on the shaft bracket 9 and restressing the connecting strap 13. Conversely, if the tension increases, the elastic metal sheet 16 moves downward, reducing the support force on the shaft bracket 9 to adapt to the new tension. By fine-tuning the nut 19, the tension of the connecting strap 13 can be precisely controlled, ensuring its stability and reliability under varying slope deformation conditions.

[0061] In a further preferred embodiment of the present invention, the connecting belt 13 is passed upward from the bottom of the belt head positioning sleeve 11, and the upper surface of the tensioning guide roller 10 when tightened is higher than the bottom of the belt head positioning sleeve 11. The height difference between the upper surface of the tensioning guide roller 10 when tightened and the bottom of the belt head positioning sleeve 11 is greater than the distance between the shaft frame 9 and the tenon clamping plate 5. The distance between the shaft frame 9 and the tenon clamping plate 5 is greater than the distance required for the anti-slip trigger plate 8 to press and trigger the deformation monitoring trigger sensor 6 when triggered.

[0062] In this embodiment, the arrangement of the connecting belt 13 and the relative positional relationship between the tensioning guide roller 10 and the belt head positioning sleeve 11 are optimized.

[0063] The connecting belt 13 extends upward from the bottom of the belt head positioning sleeve 11. This design allows the connecting belt 13 to sag naturally after passing around the tensioning belt guide roller 10, facilitating connection with another monitoring device. At the same time, because the connecting belt 13 extends from the bottom, it can also avoid unnecessary friction or interference with the belt head positioning sleeve 11 during the tensioning process.

[0064] When the tensioning roller 10 is in tension, its upper surface is higher than the bottom of the belt head positioning sleeve 11. This design ensures that the connecting belt 13 maintains a certain tension after passing around the tensioning roller 10, thereby better transmitting slope deformation information. Furthermore, the height difference between the upper surface of the tensioning roller 10 and the bottom of the belt head positioning sleeve 11 when tensioned is greater than the distance between the shaft bracket 9 and the tenon clamping plate 5. This design further ensures the stability of the connecting belt 13 in the tensioned state and prevents the connecting belt 13 from loosening or falling off due to an excessively small height difference.

[0065] Triggering Mechanism: The spacing between the shaft bracket 9 and the tenoned clamping plate 5 is designed to be greater than the spacing required for the anti-slip trigger plate 8 to press and trigger the deformation monitoring trigger sensor 6. This means that under normal circumstances, the sliding plate 7 and the anti-slip trigger plate 8 will not accidentally trigger the deformation monitoring trigger sensor 6 due to the tension of the connecting belt 13. Only when the slope deforms significantly enough, causing the tension of the connecting belt 13 to increase significantly, and then transmitted to the sliding plate 7 through the tensioning guide roller 10, can the anti-slip trigger plate 8 overcome the resistance of spring 18 and move downward a sufficient distance to trigger the deformation monitoring trigger sensor 6, and then the monitoring data will be collected and transmitted.

[0066] As the slope deforms, the tension in the connecting belt 13 changes. If the tension increases and exceeds a certain threshold, the connecting belt 13 pulls the tensioning guide roller 10 downward. Because the tensioning guide roller 10 is connected to the sliding plate 7 and the shaft frame 9, the sliding plate 7 also moves downward. When the sliding plate 7 moves to a certain extent, the anti-slip trigger plate 8 presses the deformation monitoring trigger sensor 6, triggering the collection and transmission of monitoring data.

[0067] This design is particularly suitable for geological engineering environments where long-term, continuous monitoring of slope deformation is required. In these environments, slope deformation can be very subtle and difficult to detect, necessitating a highly sensitive and reliable monitoring device to capture these changes. The sliding trigger mechanism and optimized connection belt arrangement of the present invention precisely meet this need.

[0068] By optimizing the arrangement of the connecting belt 13 and the relative positional relationship between the tensioning guide roller 10 and the belt head positioning sleeve 11, the sensitivity of the monitoring device to slope deformation is improved.

[0069] By rationally designing the spacing between the shaft frame 9 and the tenon clamping plate 5 and the triggering mechanism, false triggering caused by changes in the tension of the connecting belt 13 is avoided. The structural design of the entire monitoring device is reasonable and compact, and it can work stably under complex and changeable geological conditions.

[0070] In a further preferred embodiment of the present invention, a protective cover 20 is detachably mounted on the top of the assembly plate 1 , and the protective cover 20 is located outside a portion of the assembly block 3 , the tenon clamping plate 5 , the deformation monitoring trigger sensor 6 and the connecting belt 13 .

[0071] In this embodiment, a detachable protective cover 20 is added to the top of the assembly plate 1. This improvement not only enhances the overall safety and reliability of the device, but also provides additional protection for the monitoring equipment.

[0072] The protective cover 20 is designed to be removably mounted on the top of the assembly plate 1, covering the assembly block 3, the tenoned clamping plate 5, the deformation monitoring trigger sensor 6, and a portion of the connecting belt 13. This design is intended to prevent external factors (such as dust, moisture, and gravel) from damaging or interfering with these key components.

[0073] During installation and use, the protective cover 20 is fixed to the top of the assembly plate 1 to ensure that it completely covers the components that need protection. The removal and installation process of the protective cover 20 should be simple and easy so that it can be quickly maintained and replaced when necessary.

[0074] The protective cover 20 acts as a physical barrier, effectively isolating key components from the external environment. When the slope deforms, changes in the tension of the connecting belt 13 are transmitted via components such as the tensioning guide roller 10 and the sliding plate 7 to the deformation monitoring trigger sensor 6, triggering the collection and transmission of monitoring data. The presence of the protective cover 20 does not affect the normal operation of this process and prevents external environmental factors from interfering with the monitoring process.

[0075] Geotechnical engineering slope deformation monitoring devices are typically deployed outdoors, facing complex and changing climatic and geological conditions. The addition of the protective cover 20 enables the device to better adapt to these environmental challenges and improves its ability to operate stably over the long term.

[0076] The protective cover 20 can prevent people from accidentally touching or external objects from damaging key components, thereby improving the safety of the device; the protective cover 20 reduces the failure rate of key components due to corrosion, pollution, etc., thereby improving the reliability of the device; the detachable design allows the protective cover 20 to be easily cleaned and replaced, reducing maintenance costs; the addition of the protective cover 20 enables the device to better adapt to various complex outdoor environments, thereby increasing its scope of application.

[0077] In a further preferred embodiment of the present invention, two supporting guide rollers 21 are rotatably installed in the protective cover 20 , and the two supporting guide rollers 21 are respectively used to support corresponding connecting belts 13 .

[0078] In this embodiment, two rotatable supporting guide rollers 21 are additionally provided in the protective cover 20. This design is intended to further improve the guidance and support of the connecting belt 13, thereby enhancing the stability and reliability of the entire monitoring system.

[0079] Two supporting belt guide rollers 21 are installed at appropriate locations within the protective cover 20. Each belt guide roller is used to support a corresponding connecting belt 13. No support is required for belts without connecting belts 13. These belt guide rollers ensure that the connecting belt 13 maintains proper tension and direction during transportation, reducing friction and wear caused by bending or twisting.

[0080] During installation and use, the connecting belt 13 is first passed through the supporting belt guide roller 21 to ensure that the connecting belt 13 maintains close contact with the belt guide roller during transmission. The supporting belt guide roller 21 can rotate freely as the connecting belt moves, thereby achieving continuous support and guidance for the connecting belt.

[0081] In a further preferred embodiment of the present invention, the connecting belt 13 passes over the corresponding supporting guide roller 21 , and the upper horizontal surface of the supporting guide roller 21 and the bottom of the belt head positioning sleeve 11 are located at the same horizontal plane.

[0082] In this embodiment, a more sophisticated design is made for the guidance and support of the connecting belt 13. Specifically, the connecting belt 13 is designed to pass over the corresponding supporting guide roller 21, and the upper horizontal surface of the supporting guide roller 21 is at the same horizontal plane as the bottom of the tape head positioning sleeve 11.

[0083] By designing the connecting belt 13 to pass over the supporting belt guide roller 21, it is possible to ensure that the connecting belt maintains a stable path and tension during transportation. This design helps reduce friction between the connecting belt and the protective cover or other components, thereby extending the service life of the connecting belt and reducing noise and wear caused by friction.

[0084] The upper surface of the support guide roller 21 is aligned with the bottom of the tape head positioning sleeve 11. This design ensures that the connecting belt smoothly enters the tape head positioning sleeve 11 after passing through the support guide roller 21 without any noticeable drop or bend. This smooth transition helps maintain the tension and stability of the connecting belt, further enhancing the performance of the entire monitoring system.

[0085] In actual use, when the slope deforms, the connecting belt 13 is subjected to tension and displaced. During this displacement, the connecting belt bypasses the support guide roller 21 and continues to transport the belt. Because the upper horizontal surface of the support guide roller 21 is aligned with the bottom of the belt head positioning sleeve 11, the connecting belt can smoothly enter the belt head positioning sleeve 11 and continue to transmit information about the slope deformation.

[0086] In a further preferred embodiment of the present invention, the burrowing cone 2 is rectangular as a whole, and has a conical structure at the bottom.

[0087] In this embodiment, the overall shape of the immersion cone 2 is rectangular, which increases its stability on the ground. The rectangular structure has a larger contact area, which can better distribute the pressure of the soil on the immersion cone, preventing the device from moving or tilting due to loose soil or vibration.

[0088] The bottom of the burying cone 2 is designed to be conical, which makes it easier to insert the burying cone into the soil. The conical structure can gradually reduce the resistance of the soil to the burying cone, so that it can be inserted deeper into the soil, improving the fixity and stability of the device.

[0089] In practice, the device is easily secured to the slope by inserting the plunging cone 2 into the soil, thanks to its tapered base. The rectangular shape of the plunging cone 2 creates a large contact area with the soil, enhancing the device's stability. Furthermore, the cone's base ensures deeper penetration into the soil, further enhancing its stability and fixation.

[0090] In a further preferred embodiment of the present invention, the cross-section of the tenon of the tenon groove 4 and the tenon-carrying clamping plate 5 is "T"-shaped or dovetail-shaped.

[0091] In this embodiment, the design of the mortise and tenon 4 and the tenon-carrying clamping plate 5 is optimized. Specifically, the cross-sections of the mortise and tenon 4 and the tenon-carrying clamping plate 5 are designed to be "T"-shaped or dovetail-shaped.

[0092] T-shaped or dovetail cross-sections: These specially designed cross-sections provide enhanced locking and stability. Whether T-shaped or dovetail, their unique shape allows the tenon to fit tightly within the groove, effectively preventing loosening or displacement.

[0093] In actual application, the tenon portion of the tenon clip 5 will be inserted into the tenon groove 4, and a tight fit is achieved through the "T" or dovetail cross-sectional shape. This design makes the assembly process simple and fast, while ensuring stability after assembly.

[0094] In order to further improve the use effect of this device, in addition to the above scheme, this scheme also has the following embodiments:

[0095] The top of the burying cone 2 is provided with a rectangular slot 22, and the assembly block 3 and the assembly plate 1 are provided with an assembly hole 23. The assembly hole 23 is connected to the rectangular slot 22, and a screw column 24 is rotatably installed in the assembly hole 23. A lifting threaded column 25 is rotatably installed in the rectangular slot 22. The top of the lifting threaded column 25 is fixedly connected to the bottom end of the screw column 24. The lifting threaded column 25 is threadedly sleeved with a rectangular threaded cylinder 26, and the rectangular threaded cylinder 26 is slidably in contact with the inner wall of the rectangular slot 22. A rectangular slide 27 is fixedly installed on the bottom of the rectangular threaded cylinder 26. The bottom of the rectangular slot 22 is provided with at least one insertion opening 28, and an anti-loosening plug 29 can be slidably installed in at least one of the insertion openings 28. The top of the anti-loosening plug 29 is located in the rectangular slot 22 and is fixedly connected to the rectangular slide 27, and the bottom extends to the outside of the burying cone 2 and can be inserted into the soil layer.

[0096] In this embodiment, a rectangular slide groove 22 is provided at the top of the burial cone 2, which provides space for the assembly and adjustment of subsequent components; assembly holes 23 are provided on the assembly block 3 and the assembly plate 1, which are connected to the rectangular slide groove 22, providing a channel for the installation of the screw column 24.

[0097] The screwing post 24 is installed in the assembly hole 23, and its bottom end is fixedly connected with the top end of the lifting threaded post 25. Like this, by rotating the screwing post 24, the lifting threaded post 25 can be driven to rotate in the rectangular slot 22.

[0098] A rectangular threaded barrel 26 is threadedly sleeved on the lifting threaded column 25, and the barrel is in sliding contact with the inner wall of the rectangular chute 22. When the lifting threaded column 25 rotates, the rectangular threaded barrel 26 moves up and down along the axis of the lifting threaded column 25 due to the action of the thread.

[0099] A rectangular slide 27 is fixedly mounted at the bottom of the rectangular threaded barrel 26, allowing it to slide within the rectangular chute 22. The bottom of the rectangular chute 22 is provided with one or more insertion openings 28, through which a locking insert 29 is slidably mounted within the rectangular chute 22. Its top is fixedly connected to the rectangular slide 27. As the rectangular threaded barrel 26 moves up and down, the locking insert 29 also moves with it, allowing its bottom to penetrate into the soil, thereby enhancing the stability of the burrowing cone 2.

[0100] When the burying cone 2 needs to be fixed in the soil, it is first inserted into the soil. Then, by rotating the screw rod 24, the lifting threaded rod 25 is driven to rotate, thereby moving the rectangular threaded cylinder 26 and the rectangular slide 27 downward. As the rectangular slide 27 moves, the bottom of the anti-loosening insert 29 is gradually inserted into the soil, thereby enhancing the stability of the burying cone 2.

[0101] The core principle of this design is to use the transmission effect of the thread and the interaction of the sliding parts to achieve the insertion and removal of the anti-loosening plug 29 in the soil layer. By rotating the screw rod 24, the insertion depth of the anti-loosening plug 29 can be easily adjusted to suit different soil layers and fixing requirements.

[0102] By inserting the anti-loosening insert 29 into the soil layer, the stability of the burying cone 2 can be significantly enhanced to prevent it from displacement or tilting during use; by rotating the screw column 24, the insertion depth of the anti-loosening insert 29 can be easily adjusted to adapt to different soil layers and fixing requirements.

[0103] In another embodiment of the present invention, at least one receiving opening 30 is provided on the insertion end of the anti-loosening plug 29, and an anti-slip hook plate 31 is hingedly installed in the receiving opening 30. The anti-slip hook plate 31 can be received in the receiving opening 30 and expand outward to the soil outside the anti-loosening plug 29 during use. A sliding cavity 32 is provided on the inner wall of the receiving opening 30, and an outward-expanding resistance block 33 can be slidably installed in the sliding cavity 32. The outward-expanding resistance block 33 can resist the outward expansion of the anti-slip hook plate 31, and the outward-expanding resistance block 33 can be received in the sliding cavity 32. A spring 2 34 for resisting the outward-expanding resistance block 33 is provided in the sliding cavity 32.

[0104] In this embodiment, at least one receiving opening 30 is formed at the insertion end of the anti-loosening insert 29, and an anti-drop barb plate 31 is hingedly mounted within the receiving opening 30. The anti-drop barb plate 31 can be retracted into the receiving opening 30 when subjected to an external force. When the external force is removed, the anti-drop barb plate 31 expands outward into the soil outside the anti-loosening insert 29 through the action of an internal outward-expanding resistance block 33 and a second spring 34, forming a barb structure that effectively prevents the burrowing cone 2 from being pulled out.

[0105] Insertion process: The immersion cone 2 is inserted into the soil. As the anti-loosening insert 29 goes deeper, the anti-slip hook plate 31 is squeezed by the soil and is retained in the receiving opening 30 .

[0106] Fixing process: When the anti-loosening insert 29 reaches the predetermined depth, the insertion stops. At this time, due to the pushing force of the outward-stretching resistance block 33, the anti-loosening hook plate 31 is resisted by the outward-stretching resistance block 33 and unfolded into the soil, forming a barb structure, and the device does not need to be removed.

[0107] In another embodiment of the present invention, the screw column 24 is located in the assembly hole 23 and the fixed sleeve is provided with a friction positioning sleeve 35. The assembly hole 23 is located on one side of the tenon clamping plate 5 and is provided with a rectangular reset groove 36. A driving threaded column 37 is rotatably installed in the rectangular reset groove 36. A lateral block 38 is slidably installed in the rectangular reset groove 36. The lateral block 38 is threadedly connected with the driving threaded column 37. The lateral block 38 is located on one side of the friction positioning sleeve 35 and is fixedly installed with a rubber friction block 39. When the driving threaded column 37 drives the lateral block 38 to slide, the rubber friction block 39 conflicts with the friction positioning sleeve 35. The driving threaded column 37 is rotatably installed on the assembly block 3. The driving threaded column 37 is fixedly connected to the corresponding end of the transmission shaft 40. The protective cover 20 is rotatable. A transverse shaft 41 is installed, and the transverse shaft 41 is arranged below the corresponding tenon card plate 5 and above the transmission shaft 40. A circular gear 42 is fixedly sleeved on the transverse shaft 41, and a rack plate 43 fixedly connected to the bottom of the elastic metal sheet 16 is slidably provided below the tenon card plate 5. The rack plate 43 is meshed with the circular gear 42. A transverse plate 44 fixedly connected to the side of the assembly block 3 is provided between the transverse shaft 41 and the transmission shaft 40. A longitudinal shaft 45 is rotatably installed on the transverse plate 44. The longitudinal shaft 45 and the corresponding end of the transverse shaft 41 are both fixedly sleeved with a bevel gear 1 46, and the two bevel gears 1 46 are meshed with each other. The longitudinal shaft 45 and the corresponding end of the transmission shaft 40 are both fixedly sleeved with a bevel gear 2 47, and the two bevel gears 2 47 are meshed with each other.

[0108] In this embodiment, the portion of the screw post 24 located in the assembly hole 23 is fixed with a friction locating sleeve 35. A rectangular reset slot 36 is defined on one side of the assembly hole 23, within which a drive threaded post 37 is rotatably mounted. The rotation of the drive threaded post 37 drives a traverse block 38 to slide within the slot. The traverse block 38 is threadedly connected to the drive threaded post 37, and a rubber friction block 39 is fixedly mounted on one side of the traverse block 38 located in the friction locating sleeve 35. When the traverse block 38 slides, the rubber friction block 39 interferes with the friction locating sleeve 35, further securing the position of the screw post 24. The drive threaded post 37 is rotatably mounted on the assembly block 3 and connected to a drive shaft 40 via a series of gears and shafts. This transmission mechanism converts the rotational motion of the screw post 24 into motion of other components.

[0109] The linkage mechanism includes a transverse shaft 41, a circular gear 42, a rack plate 43, a transverse plate 44, a longitudinal shaft 45, a bevel gear 1 46 and a bevel gear 2 47. These components together constitute a linkage system, which realizes the linkage between the screw column 24 and the tenon clamping plate 5.

[0110] When the elastic metal sheet 16 is displaced, the rack plate 43 is driven to slide. When the rack plate 43 slides, the circular gear 42 is driven to rotate. When the circular gear 42 rotates, the transverse shaft 41 is driven to rotate. At this time, the bevel gear 1 46 is used to drive the longitudinal shaft 45 to rotate. When the longitudinal shaft 45 rotates, the bevel gear 2 47 is used to rotate. At this time, the transmission shaft 40 rotates, thereby rotating the drive threaded column 37. When the device is triggered, the rubber friction block 39 is used to resist the friction positioning sleeve 35 to form a stable fixation, reducing accidents.

[0111] In summary, compared with related technologies, this solution adopts a modular design. Each monitoring device is an independent module that can be installed and configured separately, which greatly improves the flexibility and convenience of installation.

[0112] This solution is highly scalable. By connecting multiple monitoring devices to form a monitoring array, comprehensive monitoring of the entire slope can be achieved. The monitoring range can be flexibly expanded as needed, and the installation locations of multiple devices can be freely adjusted.

[0113] Once deformation data exceeding the preset threshold is detected, the system will immediately issue an early warning and notify relevant personnel to take necessary response measures, effectively avoiding the occurrence of geological disasters or reducing the losses caused by them.
