Description

Technical Field

[0001] The invention belongs to the technical field of landslide monitoring, in particular to an automatic landslide monitoring device. Background Art

[0002] Landslides are a common geological disaster, which are often accompanied by huge destructive power and casualties. In order to effectively deal with landslide disasters, the field of geological disaster monitoring urgently needs an automatic monitoring device that can monitor the displacement of landslide bodies, soil moisture, rainfall and other key parameters in real time and continuously.

[0003] Existing landslide monitoring instruments usually include monitoring poles and solar panels, but there are often many problems when dealing with landslide disasters. When a landslide occurs, the landslide body will produce a huge impact force on the monitoring device, which can easily cause damage to the monitoring instrument and thus lose its monitoring function. Landslide disasters often occur in a short period of time. If the monitoring instrument cannot be recovered in time, the collected data may be lost, affecting the accuracy of landslide warning and prevention. After the monitoring instrument is damaged, it needs to be repurchased and installed, which not only increases the monitoring cost, but also delays the progress of landslide monitoring work.

[0004] In summary, how to timely recover the landslide monitoring instrument and ensure the safety of the instrument when a landslide disaster occurs has become an urgent problem for technicians in this field to solve. Therefore, it is necessary to propose an automatic landslide monitoring device. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide an automatic landslide monitoring device. When a landslide occurs, the impact plate pushes the telescopic inner rod to slide after being impacted, and transfers energy to the screw rod through the transmission chain, driving the nut base and the monitoring tube to rise, thereby realizing automatic recovery protection of the landslide monitoring instrument.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: an automatic landslide monitoring device comprises 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 arranged outside the monitoring rod, a telescopic component for transmitting the impact force is arranged between the monitoring rod and the impact plate, a gear bar is arranged on the top of the telescopic component, a telescopic hole corresponding to the gear bar is opened on the monitoring rod, the gear bar extends into the monitoring rod through the telescopic hole, a transmission shaft is rotatably connected to the inner wall of the monitoring rod, a vertical rotating gear and a main bevel gear are fixedly connected to the transmission shaft in sequence, the gear bar is meshed with the main bevel gear, the main bevel gear is meshed with a slave bevel gear, a screw rod is coaxially fixedly connected to the slave bevel gear, a fixing component for limiting the rotation position of the screw rod is arranged in the monitoring rod, a hollow underground rod is fixedly connected to the bottom of the inner wall of the monitoring rod, a monitoring tube is slidably matched with the inner wall of the underground rod, a landslide monitoring instrument is fixedly connected to the inner wall of the monitoring tube, a connecting block is fixedly connected to the top of the monitoring tube, a nut base is fixedly connected to the top of the connecting block, and the nut base is matched with the screw thread.

[0007] The following principles and beneficial effects are achieved by adopting the above scheme:

[0008] Basic principle: When a landslide occurs, the landslide body will push the impact plate, which in turn drives the gear bar of the telescopic assembly fixedly connected to the impact plate. The gear bar enters the monitoring rod through the telescopic hole and meshes with the vertical rotating gear. As the impact plate continues to push, the gear bar drives the vertical rotating gear to rotate, thereby driving the transmission shaft and the main bevel gear to rotate. The main bevel gear meshes with the slave bevel gear, driving the slave bevel gear and the screw rod coaxially fixed at its bottom to rotate horizontally. The screw rod is threaded with the nut base, so the rotation of the screw rod will drive the nut base and the monitoring tube fixedly connected to the nut base to rise in the underground rod, thereby realizing the automatic recovery protection of the landslide monitoring instrument.

[0009] Beneficial effects:

[0010] 1. The present invention realizes the automatic recovery protection of the landslide monitoring instrument when a landslide occurs through a mechanical transmission device, thereby avoiding damage to the monitoring instrument due to direct impact of the landslide body and ensuring the integrity of the monitoring data and the continuity of the monitoring work.

[0011] 2. The device of the present invention has a compact structure, the components are closely matched, and the transmission chain is reasonably designed, which ensures the stability and reliability of the device when a landslide occurs. At the same time, the buffering effect of the spring further improves the impact resistance of the device.

[0012] 3. The present invention uses solar panels to provide power for the device, realizing a green and environmentally friendly monitoring method. The solar panels are fixedly connected to the outer wall of the monitoring pole, which can make full use of solar energy resources to provide continuous power supply for the landslide monitoring instrument, reducing the monitoring cost.

[0013] 4. The device of the present invention is reasonably designed, and the components are simply connected and easy to disassemble and replace. When the device fails or needs maintenance, the staff can easily inspect and repair it, ensuring the long-term stable operation of the device.

[0014] Furthermore, an auxiliary support assembly is provided in the monitoring pole, which includes a number of "L"-shaped side support plates, which are hinged on the inner wall of the monitoring pole, one end of the side support plate is embedded and fits with the outer wall of the monitoring pole, and the other end of the side support plate is placed horizontally in the movement trajectory of the nut base.

[0015] Beneficial effect: The "L"-shaped side support plate in the auxiliary support assembly can automatically open when the nut base rises, providing additional support for the monitoring tube and the nut base. This support can effectively prevent the monitoring tube from shaking or tilting due to external pressure during the rising process, thereby enhancing the stability of the entire device when a landslide occurs.

[0016] Furthermore, the telescopic assembly includes a telescopic inner rod, and several telescopic inner rods are fixedly connected to the outer wall of the impact plate on one side close to the monitoring rod. The outer wall of the telescopic inner rod is slidably matched with a telescopic outer rod. The telescopic outer rods are all fixedly connected to the outer wall of the monitoring rod. A spring is fixedly connected between the telescopic inner rod and the telescopic outer rod. 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 bar. The inner wall of the telescopic hole is provided with a guide groove for limiting the stable sliding of the gear bar in the telescopic hole, and the outer wall of the gear bar is fixedly connected with a guide block matching the guide groove.

[0017] Beneficial effects: The spring fixedly connected between the telescopic inner rod and the telescopic outer rod plays a key role in absorbing energy when the impact plate is impacted. The elasticity of the spring can slow down the impact speed of the impact plate and convert it into the compression potential energy of the spring, thereby further reducing the impact on the landslide monitoring instrument. The end of the telescopic inner rod at the top of the monitoring rod away from the impact plate is fixedly connected to the gear bar. This design ensures that the impact of the impact plate can be directly converted into the sliding power of the gear bar. The cooperation of the guide groove and the guide block can ensure that the gear bar slides stably along the predetermined trajectory in the telescopic hole. This design effectively prevents the gear bar from deflecting or jamming during the sliding process, thereby ensuring the smooth operation of the transmission chain and the steady rise of the monitoring tube.

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

[0019] Beneficial effects: The battery, as a backup power source, can provide continuous power supply for the landslide monitoring instrument when the solar panels cannot provide enough power or when there is insufficient light in rainy weather. This design ensures that the landslide monitoring instrument can work 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, and the other end of the fixing frame is fixedly connected to a fixed rotating ring for limiting the rotation position of the screw rod, the screw rod is located in the fixed rotating ring, and a positioning block for limiting the side support plate and the monitoring tube is fixedly connected to the outer wall of the nut base away from the screw rod.

[0021] Beneficial effects: The fixed rotating ring fixedly connected to one end of the fixed frame is used to limit the rotation position of the screw. This design not only ensures the stability of the screw during the transmission process, but also makes the rotation of the screw more precise and controllable, thereby improving the accuracy of the rise or fall of the monitoring tube. The design of the positioning block can ensure that the nut base maintains a stable connection with the side support plate and the monitoring tube after the side support plate is lifted and opened. This connection not only enhances the structural stability of the entire device, but also prevents the side support plate from pushing back to reset the monitoring tube.

[0022] Furthermore, the outer walls of the side support plates are fixedly connected with a plurality of spikes for improving the gripping force when the side support plates are opened.

[0023] Beneficial Effects: The spike design can significantly improve the grip of the side support plate with the ground or landslide surface when it is open. This enhancement allows the side support plate to be more firmly fixed in place when subjected to external pressure, preventing the device from becoming unstable due to sliding 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 position is optimized to the top of the monitoring pole, which helps reduce the interference of the ground or landslide body on signal transmission. The high-position antenna can more effectively capture the signal sent by the landslide monitoring instrument and transmit it to the remote receiving device, thereby improving the transmission quality and accuracy of the signal.

[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 presence of 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 and alert them to potential dangers. This design helps to reduce the loss of life and property caused by landslide disasters. The reflective layer makes the impact plate easier to be captured by monitoring equipment during the monitoring process. This helps staff to more accurately judge the status and position of the impact plate, thereby improving the efficiency and accuracy of landslide monitoring.

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

[0029] Beneficial effects: The waterproof coating can effectively prevent moisture from penetrating into the battery, avoiding problems such as battery short circuit, damage or performance degradation caused by moisture intrusion. This design ensures that the battery can maintain stable performance under various climatic conditions and prolongs the battery life.

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

[0031] Beneficial effect: The pointed cone design of the ground cone enables it to penetrate deep into the ground, providing solid support for the ground 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 movement of landslides.

DETAILED DESCRIPTION

[0037] The following is further described in detail through specific implementation methods:

[0038] Example 1

[0039] Basically as attached Figure 1-Figure 4 As shown: an automatic 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. The top of the monitoring pole 3 is fixedly connected with an antenna 1 for transmitting the signal of a landslide monitoring instrument 24 by screws.

[0040] The monitoring rod 3 is provided with a strike plate 4 outside, which can withstand the impact of the landslide body. A telescopic assembly for transmitting the impact force is provided between the monitoring rod 3 and the strike plate 4. The telescopic assembly includes a telescopic inner rod 17. Several telescopic inner rods 17 are fixedly connected to the outer wall of the strike plate 4 near the monitoring rod 3 by bolts. The outer wall of the telescopic inner rod 17 is slidably matched with a telescopic outer rod 9. The telescopic outer rods 9 are all fixedly connected to the outer wall of the monitoring rod 3 by bolts. A spring 8 is fixedly connected between the telescopic inner rod 17 and the telescopic outer rod 9 by screws. A gear bar 11 is welded to the end of the telescopic inner rod at the top of the monitoring rod 3 away from the strike plate 4. A telescopic hole 10 corresponding to the gear bar 11 is opened on the monitoring rod 3. The inner wall of the telescopic hole 10 is opened with a guide groove for limiting the stable sliding of the gear bar 11 in the telescopic hole 10. The outer wall of the gear bar 11 is integrally formed with a guide block that cooperates with the guide groove. The meshing of the gear bar 11 with the vertical rotating gear 18 realizes the conversion of the impact force of the strike plate 4 to the transmission shaft 16. A reflective layer for improving visibility is bonded to the outer wall of the impact plate 4 away from the telescopic inner rod 17. The reflective layer improves the visibility of the device at night or in bad weather conditions.

[0041] The gear bar 11 extends into the monitoring rod 3 through the telescopic hole 10. The inner wall of the monitoring rod 3 is rotatably connected with a transmission shaft 16. The transmission shaft 16 is successively integrally formed with a vertically rotating gear 18 and a main bevel gear 12. The transmission shaft 16 converts the linear motion of the gear bar 11 into a rotary motion. The gear bar 11 is meshed with the main bevel gear 12. The main bevel gear 12 is meshed with a horizontally rotating slave bevel gear 13. The bottom of the slave bevel gear 13 is coaxially fixedly connected with a screw 15 by bolts. A fixing assembly for limiting the rotation position of the screw 15 is provided in the monitoring rod 3. The fixing assembly includes a fixing frame 19. The fixing frame 19 is welded to the inner wall of the monitoring rod 3. The other end of the fixing frame 19 is fixedly connected with a fixed rotating ring 20 for fixing the rotation position of the screw 15 by screws. The screw 15 is sleeved in the fixing ring. The threaded cooperation of the screw 15 and the nut base 21 realizes the lifting and lowering of the monitoring tube 6. The inner wall of the monitoring rod 3 is integrally formed with a hollow ground rod 25 at the bottom of the monitoring rod 3, and the bottom of the ground rod 25 is fixedly connected with a ground cone 7 by bolts. The ground rod 25 and the ground cone 7 ensure that the device is stably inserted into the soil.

[0042] The inner wall of the underground rod 25 is slidably matched with a monitoring tube 6, and the inner wall of the monitoring tube 6 is fixedly connected to a landslide monitoring instrument 24 by screws. The top of the monitoring tube 6 is fixedly connected to a connecting block 26 by screws, and the top of the connecting block 26 is fixedly connected to a nut base 21 by bolts. The outer wall of the nut base 21 away from the screw rod 15 is fixedly connected to a blocking block 23 for limiting the side support plate 5 and the monitoring tube 6 by bolts. The nut base 21 is threadedly matched with the screw rod 15. The inner wall of the monitoring rod 3 away from the screw rod 15 is fixedly connected to a battery 14 by bolts, and the outer wall of the battery 14 is coated with a waterproof coating. The landslide monitoring instrument 24 and the solar panel 2 are both electrically connected to the battery 14. The landslide monitoring instrument 24 collects data of the landslide body in real time, and the solar panel 2 charges the battery 14 to ensure long-term operation of the device.

[0043] Specific implementation steps: First, vertically insert the underground rod 25 part of the monitoring rod 3 into the ground, and the underground cone 7 penetrates into the soil to provide stable support. Adjust the impact plate 4 to be in the direction of the impact of the landslide disaster, for example, toward the top of the slope, the telescopic inner rod 17 is in an unstretched state in the telescopic outer rod 9, and the spring 8 is in a compressed state to provide support for the impact plate 4. The gear bar 11 is located in the telescopic hole 10 and remains in meshing state with the vertical rotating gear 18, and the screw rod 15 and the nut base 21 do not rotate relative to each other. The monitoring tube 6 is located in the underground rod 25, and the battery 14 supplies power to start the landslide monitoring instrument 24 to start working and continuously collect relevant data of the landslide body. The landslide monitoring instrument 24 transmits the collected data to the remote monitoring system through the antenna 1 for analysis and processing by the staff.

[0044] In a normal state, the spring 8 not only provides support for the impact plate 4, but also has the ability to buffer external impacts. When a stone, a small landslide or other object hits the impact plate 4, the spring 8 first absorbs and disperses the impact force, reducing the impact energy directly transmitted to the telescopic inner rod 17 and the gear bar 11. This buffering effect helps protect the entire transmission chain from damage caused by instantaneous large impacts, ensuring that the device can still work normally under multiple small impacts.

[0045] When a larger landslide or a stronger impact occurs, the impact force on the impact plate 4 exceeds the buffering capacity of the spring 8, causing the telescopic inner rod 17 to slide in the telescopic outer rod 9 and further stretch the spring 8. The sliding of the telescopic inner rod 17 drives the gear bar 11 to move in the telescopic hole 10, and the meshing with the vertical rotating gear 18 causes the transmission shaft 16, the main bevel gear 12 and the slave bevel gear 13 to rotate in sequence. The rotation of the slave bevel gear 13 drives the screw rod 15 to rotate, and the rotation of the screw rod 15 causes the nut base 21 that matches its thread to start rising, thereby driving the monitoring tube 6 to slide and rise along the underground rod 25 and the inner wall of the monitoring rod 3. The underground rod 25 remains inserted into the ground. During the rising process of the monitoring tube 6, the positioning block 23 on the nut base 21 slides and matches with the inner wall of the monitoring rod 3 to ensure that the monitoring tube 6 remains stable during the rising process. In the event of a landslide disaster, the monitoring tube 6 can safely recycle the landslide monitoring instrument 24 into the monitoring rod 3 to prevent it from being exposed to a harsh environment and being damaged or lost. This not only protects the safety of the landslide monitoring instrument 24, but also extends its service life. At this time, the landslide monitoring instrument 24 determines that a landslide risk or collision event occurs, and immediately triggers an alarm mechanism. The alarm signal is sent to the monitoring center or the mobile phone of relevant personnel through a preset communication method such as a 4G / NB-LOT wireless network.

[0046] When the disaster of the landslide body ends and the objects on the impact plate 4 are cleared, the user pulls the telescopic inner rod 17 back to its original position through the reset force of the spring 8, driving the gear bar 11 to reset. The reset of the gear bar 11 is driven by the transmission shaft 16 and the bevel gear, so that the screw 15 rotates in the direction, allowing the monitoring tube 6 and the impact plate 4 to return to the initial position, and the monitoring rod 3 is reinstalled. In each landslide event, the landslide monitoring instrument 24 can be recovered and protected in time, avoiding monitoring interruption caused by damage or loss. This ensures the continuity and accuracy of landslide monitoring and provides reliable data support for landslide early warning and prevention.

[0047] Example 2

[0048] Basically as attached Figure 1 and Figure 4 As shown: The difference from the above embodiment is that an auxiliary support assembly is provided inside the monitoring rod 3, and the auxiliary support assembly includes a plurality of "L"-shaped side support plates 5, which are hinged on the inner wall of the monitoring rod 3, one end of the side support plate 5 is embedded and fitted with the outer wall of the monitoring rod 3, and the other end of the side support plate 5 is placed horizontally in the motion track of the nut base 21. The outer wall of the side support plate 5 is integrally formed with a plurality of spikes 22 for improving the grip of the side support plate 5 when it is opened.

[0049] Specific implementation steps: On the basis of Example 1, after the device is installed, the side support plate 5 is in a retracted state and fits tightly against the inner wall of the monitoring rod 3. The nut base 21 is in the initial position, and the landslide monitoring instrument 24 starts to work normally. When a landslide occurs, the impact plate 4 is impacted by the landslide body. Through the transmission cooperation of the telescopic inner rod 17, the gear bar 11, the transmission shaft 16, the bevel gear and the screw 15, the nut base 21 drives the monitoring tube 6 to start rising. As the nut base 21 rises, when the side support plate 5 contacts and collides, the side support plate 5 is rapidly expanded under the action of the extrusion 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 expansion of the side support plate 5 increases the contact area between the device and the soil, and enhances the grip through the spikes 22. This design enables the device to better resist the thrust of the landslide body when a landslide occurs, reducing the displacement caused by the landslide, which helps to reduce the possibility of collapse of the monitoring rod 3 under landslide or impact, thereby ensuring the stability of the landslide monitoring instrument 24 and the accuracy of data collection. The positioning block 23 is engaged with the side support plate 5 to ensure that the side support plate 5 will not push the nut base 21 back to cause the monitoring tube 6 to reset.

[0050] When the disaster of the landslide body ends, after cleaning the objects on the impact plate 4, the nut base 21 drives the monitoring tube 6 and the landslide monitoring instrument 24 back to the initial position through the reverse movement of the transmission system. At this time, the squeezing force of the side support plate 5 disappears, and it is manually retracted back to the original position, completing the reset of the auxiliary support assembly.

[0051] The above is only an embodiment of the present invention. The common sense such as the known specific structure and characteristics in the scheme is not described in detail here. The ordinary technicians in the relevant field know all the common technical knowledge in the technical field of the invention before the application date or priority date, can obtain all the existing technologies in the field, and have the ability to apply the conventional experimental means before that date. The ordinary technicians in the relevant field can improve and implement this scheme in combination with their own abilities under the enlightenment given by this application. Some typical known structures or known methods should not become obstacles for ordinary technicians in the relevant field to implement this application. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
