Description

Technical Field

[0001] The present invention relates to the technical field of geological disaster early warning, and particularly to a method and device for monitoring and warning geological disasters. Background Art

[0002] Geological disasters result from catastrophic damage to the geological environment by natural and artificial geological actions, mainly including collapses, landslides, debris flows, ground subsidence, and ground fissures, etc.; China is one of the regions with frequent geological disasters in the world. In recent years, the research on landslides and debris flow disasters has been the focus of industry research. In order to reduce the loss of life and property caused by geological disasters and conduct regional risk prediction, before a geological disaster occurs, monitoring and warning devices are usually used for monitoring to achieve the purpose of early warning, timely evacuation of people, and protection of the life and property safety of the people. When conducting regional risk prediction, geological disaster real-time monitoring devices need to be set at multiple locations within the region. The built-in sensors can monitor the displacement changes of the ground. The geological disaster real-time monitoring device will send the displacement to the remote control center in real time. When the displacement of the ground changes greatly, the control center can quickly know where a geological disaster has occurred.

[0003] When the prior art is used to monitor and warn of landslides, fixed columns are usually installed on both sides of the landslide cracks, and then landslide extensometers are set on the fixed columns, and the landslide extensometers are connected through a pull rope. When the cracks of the landslide increase to a certain distance, the pull rope pulls the landslide extensometer to give an alarm and remind people. However, the fixed columns are all installed on the mountain. During long-term installation and use, the pull rope is very easy to be dropped on by branches and pressed or blown by strong winds, resulting in the landslide extensometer being pulled and generating false alarms. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a method and device for monitoring and warning geological disasters, which solves the problem that the pull rope is very easy to be dropped on by branches and pressed or blown by strong winds.

[0005] To achieve the above object, the present invention is realized through the following technical solutions: A geological disaster monitoring and early warning method and device, including two groups of fixed columns. An installation groove is opened at the top end of the fixed column. An electric push rod three is fixedly connected to the inner bottom wall of the installation groove. A clamping mechanism is installed at the top end of the electric push rod three. The clamping mechanism clamps an installation seat. Two landslide extensometers connected by a pull rope are respectively fixedly arranged on the side walls of the two installation seats. A protection component is installed above the pull rope. The protection component includes two shielding covers and a connecting rope. One end of each of the two shielding covers is rotatably connected to the outer wall of the corresponding installation seat through a torsion spring rotating shaft. One end of the connecting rope is fixedly connected to the shielding cover, and the other end of the connecting rope is fixedly connected with a blocking ring. A limiting groove is opened on the surface of the fixed column. The blocking ring is slidably connected with the limiting groove.

[0006] Preferably, the clamping mechanism includes a clamping groove and a clamping seat. The clamping seat is slidably installed inside the installation groove. A connecting groove is opened inside the clamping seat. A positioning column is slidably connected inside the connecting groove. An elastic member is fixedly connected to the side wall of the positioning column. The other end of the elastic member is fixedly connected with a limiting ring. The limiting ring is fixedly connected with the installation groove. The clamping groove is opened on the side wall of the installation seat. The positioning column is made of ferromagnetic material.

[0007] Preferably, an extension layer and a sliding layer are slidably connected inside one of the shielding covers. An electric push rod one is fixedly connected to the side wall of the sliding layer. The driving end of the electric push rod one is fixedly connected to the extension layer. The sliding layer is fixed inside the shielding cover through a fixing mechanism. The fixing mechanism includes a plurality of installation holes, threaded holes and bolts. The installation holes are opened on both sides of the shielding cover. The threaded holes are opened on both sides of the sliding layer. The bolts pass through the installation holes and are threadedly connected with the threaded holes. One end of the extension layer is fixedly connected with a connecting column. A connecting hole seat is fixedly connected to the inner wall of the other shielding cover.

[0008] Preferably, a U-shaped fixing frame is arranged on the outer side of the connecting rope, and the bottom end of the fixing frame is fixedly connected with the installation seat.

[0009] Preferably, the clamping mechanism further includes an installation ring. The installation ring is fixedly arranged at the top end of the electric push rod three. A magnetic column is fixedly connected to the top end of the installation ring. An opening for the magnetic column to pass through is opened at the bottom end of the installation groove.

[0010] Preferably, a limiting frame is fixedly connected to the top end of the clamping seat. A limiting protrusion is fixedly arranged on the top of the installation seat.

[0011] Preferably, an installation rope is fixedly connected to the side wall of the installation seat. A fixed pulley is slidably installed on the outer side of the installation rope. The fixed pulley is fixedly arranged on the upper side wall of the fixed column.

[0012] Preferably, the fixed column includes two support columns. A rotating shaft is rotatably connected to the lower side walls of the two support columns, and a mounting column is fixedly connected to the opposite sides of the two rotating shafts.

[0013] Preferably, a mounting bracket is fixedly connected to the outer side walls of the two support columns. A second electric push rod is rotatably connected to the side wall of the mounting bracket, and the driving end of the second electric push rod is rotatably connected to the mounting column.

[0014] Working principle: The support columns are installed on both sides of the landslide crack by means of perfusion fixation. By controlling the reverse operation of the two second electric push rods, the two mounting columns are tilted to drive the landslide extensometer to be tilted for detection, so that the measuring axis of the landslide extensometer is as consistent as possible with the possible main deformation direction of the landslide body, improving the accuracy and flexibility of the device.

[0015] By pushing the sliding layer to slide, the sliding layer drives the extension layer to slide and adjust to a suitable position. Then, bolts are passed through the mounting holes and connected to the threaded holes to fix the positions of the sliding layer and the extension layer. The position of the sliding layer is adjusted according to the installation spacing of the two fixed columns, so that the sum of the lengths of the two shielding covers and the length of the sliding layer extending out of the shielding cover is close to the length of the pull rope, making the protection component suitable for installation on both sides of landslide cracks of various sizes for protection.

[0016] When the mounting seat is clamped, the third electric push rod is controlled to contract to the minimum amplitude, so that the magnetic column is inserted into the interior of the mounting groove from the opening. Due to the suction force exerted by the magnetic column on the positioning column, the positioning column slides into the interior of the connecting groove. The construction worker pulls the mounting rope on the ground to drive the mounting seat to rise along the fixed column to the upper part of the fixed column. At this time, the third electric push rod extends to drive the clamping seat to rise, so that the magnetic column exits the opening, and the positioning column extends out of the connecting groove under the elastic force of the elastic member and can be inserted into the interior of the card slot, thereby clamping and limiting the mounting seat and the clamping seat to prevent the mounting seat from falling, so that the landslide extensometer is installed in the upper area of the landslide crack for monitoring. When the landslide extensometer needs to be maintained, the third electric push rod is controlled to contract to the minimum amplitude, so that the positioning column automatically exits the card slot, and the mounting seat can be slowly lowered through the mounting rope, facilitating the maintenance of the landslide extensometer.

[0017] During use, protection is carried out on the outside of the pull rope through the shielding cover to avoid or reduce the pulling force on the pull rope caused by windy and rainy weather and falling tree branches, reducing the probability of false alarms of the landslide extensometer. The sliding layer is pushed to slide by the extension of the electric push rod 1, so that the sliding layer is inserted into the interior of another shielding cover until the connecting column is inserted into the interior of the connecting hole seat, thereby docking the two extension layers, improving the stability during use and the bearing capacity for tree branches. And when sundries such as tree branches are pressed on the upper part of the shielding cover, control the electric push rod 1 to contract so that the sliding layer withdraws from the shielding cover, control the operation of the electric push rod 3, drive the mounting seat to rise by the extension of the electric push rod 3, and the mounting seat drives the shielding cover and the blocking ring to rise. When the blocking ring rises to the top of the limiting groove, under the limitation of the limiting groove, the blocking ring no longer rises, and a pulling force is generated on the rising shielding cover through the connecting rope, thereby pulling the shielding cover to rotate upward, so as to push the tree branches pressed on the upper part of the shielding cover to both sides and make them fall, achieving the effect of automatically cleaning the tree branches. After the cleaning is completed, the electric push rod 3 contracts, so that the pulling force of the connecting rope gradually weakens until it disappears, and the shielding cover rotates above the pull rope again through the torsion of the torsion spring rotating shaft for protection.

[0018] The present invention provides a geological disaster monitoring and early warning method and device. It has the following beneficial effects: 1. Through the shielding cover to protect on the outside of the pull rope, the present invention avoids or reduces the pulling force on the pull rope caused by windy and rainy weather and falling tree branches, reduces the probability of false alarms of the landslide extensometer, and drives the shielding cover to rotate upward by the extension of the electric push rod 3, so as to push the tree branches pressed on the upper part of the shielding cover to both sides and make them fall, achieving the effect of automatically cleaning the tree branches.

[0019] 2. By adjusting the position of the sliding layer, the present invention enables the protection component to be suitable for installation on both sides of mountain landslide cracks of various sizes for protection. And inserting the connecting column into the interior of the connecting hole seat can improve the stability and bearing capacity of the shielding cover during use.

[0020] 3. The present invention automatically generates sliding due to the different heights of the positioning columns. Thus, when the electric push rod 3 contracts with the smallest amplitude, the clamping fit between the mounting seat and the clamping seat can be cancelled, facilitating the maintenance of the landslide extensometer. When the electric push rod 3 extends, the mounting seat and the clamping seat are automatically clamped together, enabling the landslide extensometer to be installed in the area above the mountain landslide crack for monitoring, improving the installation convenience.

[0021] 4. Through the cooperation of the limiting frame and the limiting protrusion, the present invention facilitates the docking of the positioning column to the positioning groove, and limits the positioning column through the blocking rod to avoid the accidental withdrawal of the positioning column from the card slot, improving the clamping stability between the mounting seat and the clamping seat.

Detailed implementation manners

[0024] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to the attached Figure 1 - attached Figure 4, an embodiment of the present invention provides a geological disaster monitoring and early warning method and device, including two sets of fixed columns 1. An installation groove 14 is opened at the top of the fixed column 1. An electric push rod three 15 is fixedly connected to the inner bottom wall of the installation groove 14. A clamping mechanism 2 is installed at the top of the electric push rod three 15. The clamping mechanism 2 clamps an installation seat 3, and the installation seat 3 is slidably connected to the fixed column 1. Two landslide extensometers 4 connected by a pull rope are respectively fixedly arranged on the side walls of the two installation seats 3. A protection component 5 is installed above the pull rope. The protection component 5 includes two shielding covers 51 and a connecting rope 56. The shielding cover 51 is set as an arc shape or a V shape. One ends of the two shielding covers 51 are respectively rotatably connected to the outer walls of the two installation seats 3 through torsion spring shafts. The shielding cover 51 rotates downward under the torsion of the torsion spring shaft to abut against the installation seat 3. One end of the connecting rope 56 is fixedly connected to the shielding cover 51, and the other end of the connecting rope 56 is fixedly connected with a blocking ring 57. A limiting groove 16 is opened on the surface of the fixed column 1. The top height of the limiting groove 16 is less than the top height of the fixed column 1. The blocking ring 57 is slidably connected to the limiting groove 16. A camera is fixedly arranged at the top of the fixed column 1. The electric push rod three 15, the landslide extensometer 4 and the camera are electrically connected to a controller. The controller is electrically connected to a wireless communication module to send the data collected by the landslide extensometer 4 to a remote server or a monitoring center. After the remote server or the monitoring center receives the data sent by the landslide extensometer 4, professional data analysis software is used to analyze the data. Once the system determines that there is a landslide risk, an alarm mechanism will be triggered. The situation of the device and the landslide crack can be remotely viewed through the camera. When it is observed that branches have fallen above the shielding cover 51, the electric push rod three 15 can be remotely controlled to operate to achieve remote cleaning.

[0026] Specifically, the landslide extensometer 4 is protected by the shielding cover 51 to prevent wind, rain and light from directly contacting the landslide extensometer 4, thereby prolonging the service life of the landslide extensometer 4 when used in the wild. During use, the fixed column 1 is installed on both sides of the landslide crack of the mountain. The shielding cover 51 is used for protection outside the pull rope to avoid or reduce the pulling force on the pull rope caused by wind and rain weather and the falling of branches, reducing the probability of false alarms of the landslide extensometer 4. And when sundries such as branches are pressed on the shielding cover 51, the electric push rod three 15 is controlled to operate. The installation seat 3 is driven to rise by the extension of the electric push rod three 15. The installation seat 3 drives the shielding cover 51 and the blocking ring 57 to rise. When the blocking ring 57 rises to the top of the limiting groove 16, under the limitation of the limiting groove 16, the blocking ring 57 no longer rises, and a pulling force is generated on the rising shielding cover 51 through the connecting rope 56, so as to pull the shielding cover 51 to rotate upward, thereby pushing the branches pressed on the shielding cover 51 to both sides and dropping them, achieving the effect of automatically cleaning the branches. After the cleaning is completed, the electric push rod three 15 contracts, so that the pulling force of the connecting rope 56 gradually weakens until it disappears, and the shielding cover 51 rotates again above the pull rope through the torsion of the torsion spring shaft for protection.

[0027] Please refer to the attached Figure 7 - attachment Figure 8 In it, an extension layer 53 and a sliding layer 54 are slidably connected inside one of the shielding covers 51. A first electric push rod 55 is fixedly connected to the side wall of the sliding layer 54. The first electric push rod 55 is electrically connected to the controller. The driving end of the first electric push rod 55 is fixedly connected to the extension layer 53. The sliding layer 54 is fixed inside the shielding cover 51 through a fixing mechanism 6. The fixing mechanism 6 includes a plurality of mounting holes 61, threaded holes 62 and bolts 63. The mounting holes 61 are opened on both sides of the shielding cover 51. The threaded holes 62 are opened on both sides of the sliding layer 54. The bolts 63 pass through the mounting holes 61 and are threadedly connected to the threaded holes 62. One end of the extension layer 53 is fixedly connected to a connecting column 13, and a connecting hole seat 7 is fixedly connected to the inner wall of the other shielding cover 51.

[0028] Specifically, during installation, by pushing the sliding layer 54 to slide, the sliding layer 54 drives the extension layer 53 to slide and adjust to a proper position, and then the positions of the sliding layer 54 and the extension layer 53 are fixed by connecting the bolts 63 through the mounting holes 61 and the threaded holes 62. The position of the sliding layer 54 is adjusted according to the installation spacing of the two fixing columns 1, so that the total length of the two shielding covers 51 and the length of the sliding layer 54 extending out of the shielding cover 51 is close to the length of the pull rope, making the protection component 5 suitable for being installed on both sides of landslide cracks of various sizes for protection. During use, the first electric push rod 55 extends to push the sliding layer 54 to slide, so that the sliding layer 54 is inserted into the other shielding cover 51 until the connecting column 13 is inserted into the connecting hole seat 7, thereby docking the two extension layers 53, improving the stability during use and the bearing capacity for tree branches. When the tree branches need to be cleaned, the first electric push rod 55 is controlled to contract so that the sliding layer 54 withdraws from the shielding cover 51.

[0029] Please refer to the attached Figure 4 , a U-shaped fixing frame 8 is arranged on the outer side of the connecting rope 56, and the bottom end of the fixing frame 8 is fixedly connected to the mounting seat 3.

[0030] Specifically, the movement track of the connecting rope 56 is restricted by the fixing frame 8.

[0031] Please refer to the attached Figure 4 - attachment Figure 6, the clamping mechanism 2 includes a clamping groove 207 and a clamping seat 201. The clamping seat 201 is slidably installed inside the installation groove 14, and the clamping seat 201 is fixedly connected to the driving end of the electric push rod three 15. A connection groove 203 is opened inside the clamping seat 201. A positioning column 204 is slidably connected inside the connection groove 203. A resilient member 205 is fixedly connected to the side wall of the positioning column 204. The resilient member 205 can be a leaf spring, a helical spring, a torsion bar spring, a rubber spring, etc. In this embodiment, a helical spring is adopted. The other end of the resilient member 205 is fixedly connected to a limiting ring 206, and the limiting ring 206 is fixedly connected to the installation groove 14. The clamping groove 207 is opened on the side wall of the mounting seat 3. The positioning column 204 is made of a ferromagnetic material. The clamping mechanism 2 further includes an installation ring 209. The installation ring 209 is fixedly arranged at the top end of the electric push rod three 15, and the driving end of the electric push rod three 15 penetrates through the installation ring 209. A magnetic column 210 is fixedly connected to the top end of the installation ring 209. An opening for the magnetic column 210 to pass through is opened at the bottom end of the installation groove 14. A mounting rope 11 is fixedly connected to the side wall of the mounting seat 3. A fixed pulley 12 is slidably installed on the outer side of the mounting rope 11, and the fixed pulley 12 is fixedly arranged on the upper side wall of the fixed column 1.

[0032] Specifically, during installation, control the electric push rod three 15 to contract to the minimum amplitude, so that the magnetic column 210 is inserted into the installation groove 14 from the opening. Through the suction force exerted by the magnetic column 210 on the positioning column 204, the positioning column 204 slides into the connection groove 203. The construction worker pulls the mounting rope 11 on the ground to drive the mounting seat 3 to rise along the fixed column 1 above the fixed column 1. At this time, the electric push rod three 15 extends to drive the clamping seat 201 to rise, so that the magnetic column 210 exits the opening, and the positioning column 204 extends out of the connection groove 203 under the elastic force of the elastic member 205 and can be inserted into the clamping groove 207, thereby clamping and limiting the mounting seat 3 and the clamping seat 201 to prevent the mounting seat 3 from falling, so that the landslide extensometer 4 is installed in the area above the landslide crack for monitoring. When the landslide extensometer 4 needs to be maintained, control the electric push rod three 15 to contract to the minimum amplitude, so that the positioning column 204 automatically exits the clamping groove 207, and the mounting seat 3 can be slowly lowered through the mounting rope 11, which is convenient for maintaining the landslide extensometer 4.

[0033] Please refer to the appendix Figure 5 , a limiting frame 9 is fixedly connected to the top end of the clamping seat 201, and a limiting protrusion 10 is fixedly arranged on the top of the mounting seat 3.

[0034] Specifically, through the cooperation of the limiting frame 9 and the limiting protrusion 10, when the mounting seat 3 drives the limiting protrusion 10 to rise and abut against the limiting frame 9, the positioning column 204 is aligned with the positioning groove, which is convenient for the docking of the two.

[0035] Please refer to the appendix Figure 5, a top cover 17 is fixedly connected to the inner top wall of the installation groove 14. A position-blocking rod 18 is fixedly connected to the bottom of the top cover 17. A through hole is provided at the position corresponding to the position-blocking rod 18 on the card seat 201. The bottom end of the position-blocking rod 18 is higher than the magnetic column 210.

[0036] Specifically, the top cover 17 is used to block the top opening of the installation groove 14. After the mounting seat 3 is snap-connected, the electric push rod three 15 extends a certain distance again, so that the position-blocking rod 18 passes through the through hole and inserts into the inside of the connecting groove 203, thereby limiting the end of the positioning column 204 located inside the connecting groove 203, preventing the positioning column 204 from accidentally withdrawing from the card slot 207, and improving the stability of the snap connection between the mounting seat 3 and the card seat 201.

[0037] Please refer to the appendix Figure 9 - appendix Figure 10 , the fixing column 1 includes two support columns 101. The lower side walls of the two support columns 101 are rotatably connected to a rotating shaft 102. A mounting column 103 is fixedly connected to the opposite sides of the two rotating shafts 102. A mounting bracket 104 is fixedly connected to the outer side walls of the two support columns 101. An electric push rod two 105 is rotatably connected to the side wall of the mounting bracket 104. The controller is electrically connected to the electric push rod two 105, and the driving end of the electric push rod two 105 is rotatably connected to the mounting column 103.

[0038] Specifically, the support column 101 is installed by the method of perfusion fixation. The mounting column 103 can rotate along the vertical plane with the rotating shaft 102 as the midpoint. The telescopic movement of the electric push rod two 105 can push the mounting column 103 to rotate. By controlling the reverse operation of the two electric push rods two 105, the two mounting columns 103 are tilted and drive the landslide extensometer 4 to be tilted for detection, so that the measuring axis of the landslide extensometer 4 is as consistent as possible with the possible main deformation direction of the landslide body, improving the accuracy and flexibility of the device. When installed obliquely, according to the different heights of the top and bottom of the slope, the installation height of the bottom support column 101 of the slope is adjusted, so that the upper and lower groups of shielding covers 51 can be on the same straight line in the tilted state for subsequent docking of the connecting column 13 and the connecting hole seat 7. Specifically, when the pull rope is installed horizontally, the installation height of the bottom support column 101 of the slope is relatively increased. When the pull rope is installed obliquely, the installation height of the bottom support column 101 of the slope is relatively decreased.

[0039] A geological disaster monitoring and early warning method includes the following steps: S1. Install the landslide extensometers 4 on the two mounting seats 3 respectively, and connect the two groups of landslide extensometers 4 through a pull rope; S2. When the landslide body moves, the fixing column 1 on the lower side of the crack moves with the landslide body. The pull rope will pull the movable parts on the landslide extensometer 4 to move. The landslide extensometer 4 obtains the telescopic amount of the pull rope through the internal measuring device, thereby obtaining the relative displacement of the fixing columns 1 on both sides of the crack, that is, the deformation condition of the landslide body. S3. The landslide extensometer 4 collects the displacement data and compares the real-time displacement data with a preset threshold value. The preset threshold value is determined according to factors such as the geological conditions of the landslide body, historical data, and relevant standards. If the displacement data exceeds the threshold value, the landslide extensometer 4 determines that a landslide geological disaster may occur at this time; S4. If it is determined that a landslide geological disaster may occur, the landslide extensometer 4 issues an alarm through the warning device. The alarm method can be a sound alarm, a light alarm, etc., to notify the on-site personnel to pay attention to check and take disaster avoidance measures. At the same time, the warning information can also be sent to the remote server or monitoring center through the wireless communication module.

The geological disaster monitoring and early warning device according to claim 8, characterized in that: A mounting bracket (104) is fixedly connected to the outer side walls of the two support columns (101). An electric push rod II (105) is rotatably connected to the side wall of the mounting bracket (104), and the driving end of the electric push rod II (105) is rotatably connected to the mounting column (103).

10. A geological disaster monitoring and early warning method, characterized in that, For a geological disaster monitoring and early warning device according to any one of claims 1-9, the method comprises the following steps: S1. Mount the landslide extensometers (4) on the two mounting bases (3) respectively, and connect the two groups of landslide extensometers (4) through a pulling rope; S2. When the landslide body moves, the fixed column (1) on the lower side of the crack moves with the landslide body. The pulling rope will pull the movable component on the landslide extensometer (4) to move. The landslide extensometer (4) obtains the telescopic amount of the pulling rope through the internal measuring device, thereby obtaining the relative displacement of the fixed columns (1) on both sides of the crack, that is, the deformation condition of the landslide body; S3. The landslide extensometer (4) collects the displacement data and compares the real-time displacement data with a preset threshold. If the displacement data exceeds the threshold, at this time, the landslide extensometer (4) determines that a landslide geological disaster may occur; S4. If it is determined that a landslide geological disaster may occur, the landslide extensometer (4) issues an alarm through the warning device to notify the on-site personnel to pay attention to check and take disaster avoidance measures. At the same time, the warning information can also be sent to a remote server or a monitoring center through a wireless communication module.
