Description

Technical Field

[0001] This invention belongs to the field of landslide monitoring technology, specifically an automated landslide monitoring device. Background Technology

[0002] Landslides, as a common geological hazard, are often accompanied by enormous destructive power and casualties. In order to effectively respond to landslide disasters, the field of geological hazard monitoring urgently needs an automated monitoring device that can monitor key parameters such as landslide displacement, soil moisture, and rainfall in real time and continuously.

[0003] Existing landslide monitoring instruments typically consist of a monitoring pole and a solar panel, but they often present numerous problems when responding to landslide disasters. During a landslide, the landslide body exerts a tremendous impact on the monitoring device, easily damaging it and rendering it ineffective. Landslides often occur within a short period; if the monitoring instrument cannot be retrieved in time, collected data may be lost, affecting the accuracy of landslide early warning and prevention. Damaged monitoring instruments require replacement and reinstallation, increasing monitoring costs and delaying landslide monitoring efforts.

[0004] In conclusion, how to promptly retrieve landslide monitoring instruments and ensure their safety during landslide disasters has become an urgent problem for technicians in this field. Therefore, it is necessary to propose an automated landslide monitoring device. Summary of the Invention

[0005] To address the aforementioned problems, the present invention aims to provide an automated landslide monitoring device. When a landslide occurs, the impact plate is pushed by the impact to slide the telescopic inner rod, and the energy is transmitted to the lead screw through the transmission chain, driving the nut base and monitoring cylinder to rise, thereby achieving automatic retrieval and protection of the landslide monitoring instrument.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: An automated landslide monitoring device includes a monitoring rod and a solar panel. The solar panel is fixedly connected to the outer wall of the monitoring rod. An impact plate is provided outside the monitoring rod. A telescopic component for transmitting impact force is provided between the monitoring rod and the impact plate. A gear rack is provided at the top of the telescopic component. A telescopic hole corresponding to the gear rack is opened on the monitoring rod. The gear rack extends into the monitoring rod through the telescopic hole. A drive shaft is rotatably connected to the inner wall of the monitoring rod. A vertical rotating gear and a main bevel gear are fixedly connected in sequence on the drive shaft. The gear rack meshes with the main bevel gear. The main bevel gear meshes with a driven bevel gear. A lead screw is coaxially fixedly connected to the driven bevel gear. A fixing component for limiting the rotation position of the lead screw is provided inside the monitoring rod. A hollow ground-entry rod is fixedly connected to the bottom of the inner wall of the monitoring rod. A monitoring cylinder is slidably fitted to the inner wall of the ground-entry rod. A landslide monitoring instrument is fixedly connected to the inner wall of the monitoring cylinder. A connecting block is fixedly connected to the top of the monitoring cylinder. A nut base is fixedly connected to the top of the connecting block. The nut base is threadedly engaged with the lead screw.

[0007] The above scheme achieves the following principles and beneficial effects:

[0008] Basic Principle: When a landslide occurs, the landslide body pushes the impact plate, which in turn drives the gear rack of the telescopic assembly fixedly connected to the impact plate. The gear rack enters the monitoring rod through the telescopic hole and meshes with the vertical rotating gear. As the impact plate continues to push, the gear rack drives the vertical rotating gear to rotate, which in turn drives the transmission shaft and the main bevel gear to rotate. The main bevel gear meshes with the driven bevel gear, driving the driven bevel gear and the lead screw fixed coaxially at its bottom to rotate laterally. The lead screw is threaded into the nut base, so the rotation of the lead screw causes the nut base and the monitoring cylinder fixedly connected to the nut base to rise inside the ground-entry rod, thereby achieving automatic retrieval and protection of the landslide monitoring instrument.

[0009] Beneficial effects:

[0010] 1. This invention achieves automatic retrieval and protection of landslide monitoring instruments when a landslide occurs through a mechanical transmission device, avoiding damage to the monitoring instruments due to the direct impact of the landslide body, and ensuring the integrity of monitoring data and the continuity of monitoring work.

[0011] 2. The device of this invention has a compact structure, with close cooperation between its components and a reasonable transmission chain design, ensuring the stability and reliability of the device during landslides. At the same time, the buffering effect of the springs further improves the device's impact resistance.

[0012] 3. This invention utilizes solar panels to power the device, achieving a green and environmentally friendly monitoring method. The solar panels are fixedly connected to the outer wall of the monitoring pole, making full use of solar energy resources to provide a continuous power supply for the landslide monitoring instrument and reducing monitoring costs.

[0013] 4. The device of this invention has a reasonable design, with simple connections between components, making it easy to disassemble and replace. When the device malfunctions or requires maintenance, staff can easily inspect and repair it, ensuring the long-term stable operation of the device.

[0014] Furthermore, the monitoring rod is equipped with an auxiliary support assembly, which includes several "L"-shaped side support plates. The side support plates are hinged to the inner wall of the monitoring rod, with one end of the side support plate embedded and fitted against the outer wall of the monitoring rod, and the other end of the side support plate placed laterally in the movement trajectory of the nut base.

[0015] Beneficial effects: The "L"-shaped side support plates in the auxiliary support assembly automatically expand when the nut base rises, providing additional support for the monitoring cylinder and the nut base. This support effectively prevents the monitoring cylinder from swaying or tilting due to external pressure during its ascent, thereby enhancing the stability of the entire device during landslides.

[0016] Furthermore, the telescopic assembly includes telescopic inner rods, several of which are fixedly connected to the outer wall of the impact plate near the monitoring rod. Telescopic outer rods are slidably fitted onto the outer wall of the telescopic inner rods, and all telescopic outer rods are fixedly connected to the outer wall of the monitoring rod. Springs are fixedly connected between the telescopic inner rods and the telescopic outer rods. The end of the telescopic inner rod located at the top of the monitoring rod away from the impact plate is fixedly connected to the gear rack. The inner wall of the telescopic hole has a guide groove for limiting the stable sliding of the gear rack within the telescopic hole. A guide block that mates with the guide groove is fixedly connected to the outer wall of the gear rack.

[0017] Beneficial Effects: The spring fixedly connected between the inner and outer telescopic rods plays a crucial role in absorbing energy when the impact plate is subjected to impact. The spring's elasticity reduces the impact velocity of the impact plate and converts it into the spring's compressive potential energy, thereby further reducing the impact on the landslide monitoring instrument. The end of the inner telescopic rod located at the top of the monitoring rod, away from the impact plate, is fixedly connected to the gear rack. This design ensures that the impact of the impact plate is directly converted into the sliding power of the gear rack. The cooperation between the guide groove and the guide block ensures that the gear rack slides stably along a predetermined trajectory within the telescopic hole. This design effectively prevents the gear rack from deviating or jamming during sliding, thus ensuring the smooth operation of the transmission chain and the stable rise of the monitoring cylinder.

[0018] Furthermore, a storage battery is fixedly connected to the inner wall of the monitoring rod away from the lead screw, and both the landslide monitoring instrument and the solar panel are electrically connected to the storage battery.

[0019] Beneficial effects: As a backup power source, the battery provides continuous power to landslide monitoring instruments when solar panels cannot provide sufficient power or when there is insufficient sunlight, such as during cloudy or rainy weather. This design ensures that the landslide monitoring instruments can operate normally under various environmental conditions, improving the continuity and accuracy of monitoring.

[0020] Furthermore, the fixing assembly includes a fixing frame, which is fixedly connected to the inner wall of the monitoring rod. The other end of the fixing frame is fixedly connected to a fixing rotating ring for limiting the rotation position of the lead screw. The lead screw is located inside the fixing rotating ring. A locking block for limiting the side support plate and the monitoring cylinder is fixedly connected to the outer wall of the nut base away from the lead screw.

[0021] Beneficial effects: A fixed rotating ring, fixedly connected to one end of the fixed frame, limits the rotational position of the lead screw. This design not only ensures the stability of the lead screw during transmission but also makes its rotation more precise and controllable, thereby improving the accuracy of the monitoring cylinder's ascent or descent. The locking block design ensures that the nut base maintains a stable connection with the side support plate and the monitoring cylinder after the side support plate is raised and opened. This connection not only enhances the structural stability of the entire device but also prevents the side support plate from pushing back and resetting the monitoring cylinder.

[0022] Furthermore, the outer walls of the side support plates are fixedly connected with several spikes to improve the grip when the side support plates are spread out.

[0023] Beneficial effects: The spiked design significantly improves the grip of the side braces on the ground or landslide surface when extended. This reinforcement allows the side braces to remain more firmly in place under external pressure, preventing instability caused by slippage or tilting.

[0024] Furthermore, an antenna for transmitting signals from landslide monitoring instruments is fixedly connected to the top of the monitoring pole.

[0025] Beneficial effects: The antenna's position is optimized to the top of the monitoring pole, which helps reduce interference from the ground or landslide body on signal transmission. The high-positioned antenna can more effectively capture signals sent by the landslide monitoring instrument and transmit them to the remote receiving device, thereby improving signal transmission quality and accuracy.

[0026] Furthermore, a reflective layer for improving visibility is fixedly connected to the outer wall of the impact plate on the side away from the telescopic inner rod.

[0027] Beneficial Effects: The reflective layer enhances the warning effect of the impact plate. When a landslide occurs, the impact plate may be impacted and move, and the reflective layer can immediately attract people's attention, alerting them to potential danger. This design helps reduce the loss of life and property caused by landslides. The reflective layer also makes the impact plate easier for monitoring equipment to capture during the monitoring process. This helps staff to more accurately determine the state and location of the impact plate, thereby improving the efficiency and accuracy of landslide monitoring.

[0028] Furthermore, the outer wall of the battery is fixedly connected with a waterproof coating.

[0029] Beneficial effects: The waterproof coating effectively prevents moisture from penetrating into the battery, avoiding problems such as short circuits, damage, or performance degradation caused by moisture intrusion. This design ensures that the battery maintains stable performance under various climatic conditions, extending its lifespan.

[0030] Furthermore, a ground-penetrating cone is fixedly connected to the bottom of the ground-penetrating rod.

[0031] Beneficial effects: The pointed cone design of the ground-penetrating cone allows it to penetrate deep into the ground, providing robust support for the ground-penetrating rod. This support not only enhances the stability of the entire monitoring device but also prevents the device from tilting or collapsing due to loose soil or landslide movement.

[0037] The following detailed description illustrates the specific implementation method:

[0038] Example 1

[0039] The basics are as follows: Figures 1-4 As shown: An automated landslide monitoring device includes a monitoring pole 3 and a solar panel 2. The solar panel 2 provides continuous power support for the device. The solar panel 2 is fixedly connected to the outer wall of the monitoring pole 3 by bolts. An antenna 1 for transmitting signals from the landslide monitoring instrument 24 is fixedly connected to the top of the monitoring pole 3 by screws.

[0040] An impact plate 4 is provided outside the monitoring rod 3, which can withstand the impact of the landslide. A telescopic assembly for transmitting the impact force is provided between the monitoring rod 3 and the impact plate 4. The telescopic assembly includes telescopic inner rods 17. Several telescopic inner rods 17 are fixedly connected to the outer wall of the impact plate 4 near the monitoring rod 3 by bolts. Telescopic outer rods 9 are slidably fitted on the outer wall of the telescopic inner rods 17. All telescopic outer rods 9 are fixedly connected to the outer wall of the monitoring rod 3 by bolts. Springs 8 are fixedly connected between the telescopic inner rods 17 and the telescopic outer rods 9 by screws. A gear rack 11 is welded to the end of the telescopic inner rod at the top of the monitoring rod 3 away from the impact plate 4. The monitoring rod 3 has a telescopic hole 10 corresponding to the gear rack 11. The inner wall of the telescopic hole 10 has a guide groove for limiting the stable sliding of the gear rack 11 within the telescopic hole 10. The outer wall of the gear rack 11 has a guide block integrally formed to cooperate with the guide groove. The meshing of the gear rack 11 with the vertical rotating gear 18 realizes the conversion of the impact force of the impact plate 4 to the transmission shaft 16. A reflective layer for improving visibility is adhered to the outer wall of the impact plate 4 on the side away from the telescopic inner rod 17. The reflective layer improves the visibility of the device at night or in inclement weather conditions.

[0041] The gear rack 11 extends into the monitoring rod 3 through the telescopic hole 10. A drive shaft 16 is rotatably connected to the inner wall of the monitoring rod 3. A vertical rotating gear 18 and a main bevel gear 12 are integrally formed on the drive shaft 16 in sequence. The drive shaft 16 converts the linear motion of the gear rack 11 into rotational motion. The gear rack 11 meshes with the main bevel gear 12, which meshes with a laterally rotating driven bevel gear 13. A lead screw 15 is coaxially fixed to the bottom of the driven bevel gear 13 by bolts. The monitoring rod 3 is provided with a fixing assembly for limiting the rotational position of the lead screw 15. The fixing assembly includes a fixing frame 19, which is welded to the inner wall of the monitoring rod 3. The other end of the fixing frame 19 is fixedly connected to a fixing rotating ring 20 for fixing the rotational position of the lead screw 15 by screws. The lead screw 15 is sleeved in the fixing ring. The threaded engagement between the lead screw 15 and the nut base 21 enables the raising and lowering of the monitoring cylinder 6. The monitoring rod 3 has a hollow grounding rod 25 integrally formed at the bottom of its inner wall. The grounding rod 25 is fixedly connected to a grounding cone 7 by bolts. The grounding rod 25 and the grounding cone 7 ensure that the device is stably inserted into the soil.

[0042] A monitoring cylinder 6 is slidably fitted onto the inner wall of the ground-mounted rod 25. A landslide monitoring instrument 24 is fixedly connected to the inner wall of the monitoring cylinder 6 via screws. A connecting block 26 is fixedly connected to the top of the monitoring cylinder 6 via screws. A nut base 21 is fixedly connected to the top of the connecting block 26 via bolts. A locking block 23 for limiting the side support plate 5 and the monitoring cylinder 6 is fixedly connected to the outer wall of the nut base 21 away from the lead screw 15 via bolts. The nut base 21 is threadedly engaged with the lead screw 15. A storage battery 14 is fixedly connected to the inner wall of the monitoring rod 3 away from the lead screw 15 via bolts. The outer wall of the storage battery 14 is coated with a waterproof coating. Both the landslide monitoring instrument 24 and the solar panel 2 are electrically connected to the storage battery 14. The landslide monitoring instrument 24 collects landslide data in real time, and the solar panel 2 charges the storage battery 14, ensuring long-term operation of the device.

[0043] Specific implementation steps: First, vertically insert the ground-penetrating rod 25 of the monitoring rod 3 into the ground, with the ground-penetrating cone 7 penetrating deep into the soil to provide stable support. Adjust the impact plate 4 to be positioned in the direction of the landslide impact, for example, towards the top of the slope. The telescopic inner rod 17 is in an unstretched state within the telescopic outer rod 9, and the spring 8 is in a compressed state, providing support force for the impact plate 4. The gear rack 11 is located within the telescopic hole 10, maintaining mesh with the vertical rotating gear 18, and the lead screw 15 does not rotate relative to the nut base 21. The monitoring cylinder 6 is located within the ground-penetrating rod 25, and the battery 14 provides power to start the landslide monitoring instrument 24, continuously collecting relevant data from the landslide. The landslide monitoring instrument 24 transmits the collected data to the remote monitoring system via the antenna 1 for analysis and processing by personnel.

[0044] Under normal conditions, spring 8 not only provides support for impact plate 4 but also has the ability to buffer external impacts. When rocks, small landslides, or other objects strike impact plate 4, spring 8 first absorbs and disperses the impact force, reducing the impact energy directly transmitted to telescopic inner rod 17 and gear rack 11. This buffering effect helps protect the entire transmission chain from damage by instantaneous large impacts, ensuring that the device can still function normally under multiple small impacts.

[0045] In the event of a large landslide or a more severe impact, the impact force on the impact plate 4 exceeds the buffering capacity of the spring 8, causing the inner telescopic rod 17 to slide within the outer telescopic rod 9 and further stretch the spring 8. The sliding of the inner telescopic rod 17 drives the gear rack 11 to move within the telescopic hole 10, and its meshing with the vertical rotating gear 18 causes the transmission shaft 16, the main bevel gear 12, and the driven bevel gear 13 to rotate sequentially. The rotation of the driven bevel gear 13 drives the lead screw 15 to rotate, causing the nut base 21, which is threaded onto it, to rise. This, in turn, causes the monitoring cylinder 6 to slide upwards along the inner wall of the ground-inserting rod 25 and the monitoring rod 3. The ground-inserting rod 25 remains inserted into the ground. During the ascent of the monitoring cylinder 6, the locking block 23 on the nut base 21 slides against the inner wall of the monitoring rod 3, ensuring the monitoring cylinder 6 remains stable during ascent. In the event of a landslide, the monitoring cylinder 6 can safely retrieve the landslide monitoring instrument 24 into the monitoring rod 3, preventing it from being damaged or lost due to exposure to harsh environments. This not only protects the safety of the landslide monitoring instrument 24 but also extends its service life. When the landslide monitoring instrument 24 detects a landslide risk or impact event, it immediately triggers an alarm mechanism. The alarm signal is sent to the monitoring center or relevant personnel's mobile phones via a preset communication method, such as a 4G / NB-IoT wireless network.

[0046] When the landslide event ends and the objects on the impact plate 4 are cleared, the operator uses the restoring force of the spring 8 to pull the telescopic inner rod 17 back to its original position, causing the gear rack 11 to reset. The reset of the gear rack 11, through the transmission shaft 16 and the bevel gear, causes the lead screw 15 to rotate, returning the monitoring cylinder 6 and the impact plate 4 to their initial positions, allowing the monitoring rod 3 to be reinstalled. In each landslide event, the landslide monitoring instrument 24 can be promptly retrieved and protected, preventing monitoring interruptions due to damage or loss. This ensures the continuity and accuracy of landslide monitoring, providing reliable data support for landslide early warning and prevention.

[0047] Example 2

[0048] The basics are as follows: Figure 1 and Figure 4 As shown: Unlike the embodiments described above, the monitoring rod 3 is equipped with an auxiliary support assembly. This assembly includes several L-shaped side support plates 5, which are hinged to the inner wall of the monitoring rod 3. One end of each side support plate 5 is embedded and fitted against the outer wall of the monitoring rod 3, while the other end is placed laterally in the movement trajectory of the nut base 21. The outer wall of each side support plate 5 is integrally formed with several spikes 22 to improve grip when the side support plate 5 is extended.

[0049] Specific implementation steps: Based on Example 1, after the device is installed, the side support plate 5 is in a retracted state, tightly fitting against the inner wall of the monitoring rod 3. The nut base 21 is in its initial position, and the landslide monitoring instrument 24 begins normal operation. When a landslide occurs, the impact plate 4 is impacted by the landslide body. Through the transmission cooperation of the telescopic inner rod 17, gear rack 11, drive shaft 16, bevel gear, and lead screw 15, the nut base 21 drives the monitoring cylinder 6 to rise. As the nut base 21 rises, when the side support plate 5 makes contact and collides, it rapidly unfolds under the action of compressive force. The spikes 22 of the side support plate 5 are partially embedded in the soil, providing additional support for the monitoring rod 3. The unfolding of the side support plate 5 increases the contact area between the device and the soil, and the spikes 22 enhance the grip. This design allows the device to better resist the thrust of the landslide body during a landslide, reducing displacement caused by the landslide. This helps to reduce the possibility of the monitoring rod 3 collapsing under landslide or impact, thereby ensuring the stability of the landslide monitoring instrument 24 and the accuracy of data acquisition. The locking block 23 engages with the side support plate 5, ensuring that the side support plate 5 will not push the nut base 21 back, causing the monitoring cylinder 6 to reset.

[0050] When the landslide subsides and the objects on the impact plate 4 are cleared, the nut base 21 drives the monitoring cylinder 6 and the landslide monitoring instrument 24 back to their initial positions via the reverse movement of the transmission system. At this time, the compressive force on the side support plate 5 disappears, and it is manually retracted back to its original position, completing the reset of the auxiliary support components.
