Description

Technical Field

[0001] This application relates to the field of geological testing, and in particular to a geological loosening detection and early warning device for geological testing. Background Technology

[0002] Today, natural disasters such as landslides, collapses, and debris flows are fierce, but they often have clear warning signs before they occur. Regularly conducting simple measurements of cracks in landslides, collapses, and buildings is the most effective way to prevent casualties. Currently, commonly used simple monitoring methods include the stake method, the nail method, the painting method, and the patch method. For example, the stake method is suitable for embedding stakes on both sides of cracks in a landslide body, using a steel tape measure to measure the distance between the stakes to understand the landslide deformation and sliding process; the nail method involves driving a nail into each side of a crack in a building, and measuring the change in the distance between the two nails on both sides to determine the landslide deformation and sliding.

[0003] A landslide is a natural phenomenon in which soil or rock masses on a slope slide downhill, either as a whole or in parts, under the influence of gravity, due to factors such as river erosion, groundwater activity, rainwater soaking, earthquakes, and artificial slope cutting. The moving rock (soil) mass is called a displaced body or sliding body, while the underlying rock (soil) mass that has not moved is called a sliding bed.

[0004] Before a landslide occurs, there will naturally be slight deformations and movements as warning signs. However, although existing simple monitoring methods such as pile driving and nail driving can detect sliding changes, they cannot provide timely warnings and are not timely or effective, which can easily lead to delays in prevention. Summary of the Invention

[0005] The purpose of this application is to solve the problem that existing monitoring methods are unable to provide timely early warning of signs of landslides, resulting in delayed prevention and increased potential dangers. Compared with the existing technology, this application provides a geological loosening detection and early warning device for geological testing. Multiple cross-slot ropes are connected to the side end of the buried cylinder. The end of the cross-slot rope away from the buried cylinder is fixedly connected to a nail. The inside of the buried cylinder is equipped with a fixed rod. The outer end of the fixed rod is rotatably connected to an upper and a lower notch plate distributed vertically. The notch ends of the upper and lower notch plates are fixedly connected to a magnetic conductive layer. A portion of the cross-slot ropes moves through the buried cylinder and is located inside the notch of the upper notch plate. Another portion of the cross-slot ropes moves through the buried cylinder and is located inside the notch of the lower notch plate. The side ends of the upper and lower notch plates are provided with arc-shaped grooves. A pair of sliders are fixedly connected to the inner wall of the buried cylinder. The pair of sliders are slidably connected to the inside of the pair of arc-shaped grooves.

[0006] A pair of main magnetic blocks are fixedly connected inside the fixed rod. The pair of main magnetic blocks are located at the center of the upper and lower missing disks respectively. A pair of auxiliary magnetic blocks are fixedly connected to the inner walls of the upper and lower missing disks. The ends of the pair of auxiliary magnetic blocks that are close to each other are opposite poles. A laser lamp is fixedly connected to the inner bottom surface of the buried cylinder. A light-transmitting sheet is fixedly connected to the upper end of the buried cylinder. The upper end of the fixed rod is fixedly connected to the lower end of the light-transmitting sheet.

[0007] By installing this application in a crack in the geological geology to be monitored, and extending it vertically along the geological surface, spanning multiple cracks, when the geology deforms and moves, the sliding part will cause the corresponding embedded nails or embedded cylinders to move downwards together, causing tension on part of the cross-crack rope. When the geological deformation reaches the degree of movement, the cross-crack rope detaches from the embedded cylinder, causing the unrestrained upper or lower notch to rotate automatically under the action of magnetic force until the upper and lower notches are aligned at the gaps, allowing the laser light to pass smoothly through the pair of gaps and be emitted into the air, providing monitoring personnel with timely and effective long-distance light warning, enabling monitoring personnel to take timely precautions against geological hazards, and effectively reducing casualties.

[0008] Furthermore, the cross-slit rope includes a rope body that is fixedly connected to the embedded nail, and a T-shaped stop is fixedly connected to the end of the rope body away from the embedded nail. The T-shaped stop moves through the embedded cylinder and is in an interference fit with its interior.

[0009] Furthermore, a magnetic sheet is fixedly connected to the end of the T-shaped stop away from the rope, and the magnetic sheet attracts the corresponding magnetic conductive layer.

[0010] Furthermore, the pair of sliders are on the same vertical line, and the maximum rotation angle of the sliders in the arc groove is 180°.

[0011] Furthermore, a cylindrical groove is provided at the lower end of the upper notch, and a positioning rod is slidably connected inside the cylindrical groove. A positioning groove matching the positioning rod is provided at the upper end of the lower notch.

[0012] Furthermore, the length of the positioning rod is less than the depth of the cylindrical groove but greater than the depth of the positioning groove, and the ratio of the diameter of the positioning groove to the diameter of the positioning rod is 2-3:1.

[0013] Furthermore, in the initial use state: the notches of the upper and lower notches are located on both sides of the fixed rod, the positioning rod and the positioning groove are also located on both sides of the fixed rod, and the ends of the auxiliary magnetic block and the main magnetic block that are close to each other are of the same pole.

[0014] Furthermore, a deep-buried cone is fixedly connected to the lower end of the buried cylinder, and a stabilizing airbag is fixedly connected to the side end of the buried cylinder. The stabilizing airbag is located between the deep-buried cone and the cross-seam rope.

[0015] A geological loosening detection and early warning device for geological testing, the method of use of which is as follows:

[0016] S1. Install the buried cylinder in a crack in the slope, wherein: the part below the cross-crack rope is located inside the crack, and the part above the cross-crack rope is located on the upper side of the slope surface;

[0017] S2. Extend the multiple cross-crack ropes located at the upper gap and the multiple cross-crack ropes located at the lower gap along the slope surface upward and downward respectively, until the cross-crack ropes are nearly straight and the cross-crack ropes span at least one crack.

[0018] S3. Secure the embedded nails to the slope with bolts to define the position of the cross-seam rope;

[0019] S4. When the slope undergoes significant deformation and movement, some of the cross-slot ropes move along with the sliding part of the slope, causing the cross-slot ropes to separate from the buried cylinder. The upper or lower missing plate rotates, causing the gaps between the two to align. The light emitted by the laser light is emitted into the air through the gap and the light-transmitting plate, forming a light warning.

[0020] S5. After the inspectors observed the light, they took precautions to prevent danger on the slope and recovered and reused the cross-span rope and buried cylinder.

[0021] Furthermore, in step S5, when the embedded cylinder is used again, the magnetic conductive layer can be attracted by an external magnet, thereby guiding the rotated upper or lower notch back to its original position, making it easier for the cross-slit rope to be inserted into its notch.

[0022] Compared to existing technologies, the advantages of this application are:

[0023] (1) By installing this application in a crack in the geological surface to be monitored and extending it vertically along the geological surface, spanning multiple cracks, when the geological deformation and movement occur, the sliding part will drive the corresponding buried nail or buried cylinder to move down together, causing some of the cross-crack ropes to be pulled. When the geological deformation reaches the degree of movement, the cross-crack ropes will detach from the buried cylinders, so that the unrestricted upper or lower missing plate will automatically rotate under the action of magnetic force until the upper and lower missing plates are aligned at the gap, so that the laser light can pass smoothly through the pair of gaps and be emitted into the air, providing the monitoring personnel with timely and effective long-distance light warning effect, enabling the monitoring personnel to take timely precautions against the geological conditions with signs of disaster, and effectively reducing casualties.

[0024] (2) When the crack where the buried cylinder is located or the crack below it deforms, the slope structure of this part will drive the buried nail at its upper end to move down the slope together. The cross rope connected to this part of the buried nail will be gradually pulled. When the slope moves down to a certain extent, the buried nail will drive the cross rope to detach from the buried cylinder. When multiple cross ropes at the gap of the upper missing plate are moved out of the buried cylinder due to the landslide, the upper missing plate will rotate 180° under the magnetic force of the main magnetic block and the auxiliary magnetic block until the magnetic force stabilizes. At this time, the gaps of the upper missing plate and the lower missing plate are aligned, and the laser light will be emitted into the air through the pair of gaps to provide light warning to the monitoring personnel.

[0025] (3) When the crack above the buried cylinder deforms, the slope structure below the crack will drive the buried cylinder and the buried nail to move down the slope together. Meanwhile, the multiple buried nails above the crack remain fixed on the slope that has not moved. Therefore, when the slope moves down to a certain extent, as the buried cylinder moves down, multiple cross-slit ropes at the gap of the lower missing plate will detach from the buried cylinder, causing the lower missing plate to rotate 180° under the action of magnetic force and form a gap alignment state with the upper missing plate. The laser light will also be emitted into the air through this pair of gaps to provide light warning to the monitoring personnel.

[0026] (4) When the cracks on the upper and lower sides of the buried cylinder move downward to different degrees, that is, when the buried cylinder and the buried nail below it move asynchronously, the cross ropes at the gaps of the upper and lower missing plates are pulled. When the upper and lower missing plates lose the limit of the cross ropes and rotate, due to the cooperation of the arc groove and the slider, the two rotate in opposite directions. Therefore, after the two rotate a certain angle, the positioning rod just reaches the positioning groove position. The positioning rod enters the positioning groove under its own weight, restricting the rotation of the upper and lower missing plates. At this time, the two gaps are just aligned, so that the laser light can pass smoothly through the pair of gaps and shoot out into the air to provide light warning to the monitoring personnel.

[0027] (5) When the buried cylinder is reused, the magnetic conductive layer can be attracted by an external magnet. That is, the magnetic attraction of the external magnet to the magnetic conductive layer is greater than the magnetic attraction between the main magnetic block and the auxiliary magnetic block, thereby guiding the rotated upper or lower missing plate to return to its original position, so that the cross-slit rope can be inserted into its gap.

[0043] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0044] Example:

[0045] Please see Figure 1 and Figure 2 This application discloses a geological loosening detection and early warning device for geological testing, including a buried cylinder 3. Multiple cross-crack ropes 2 are connected to the side end of the buried cylinder 3. A nail 1 is fixedly connected to the end of the cross-crack rope 2 away from the buried cylinder 3. In use, the buried cylinder 3 is installed into one of the cracks in the slope. The other end of the cross-crack rope 2 can be fixed at a distance from the buried cylinder 3 by multiple cracks through the nail 1, thereby realizing large-scale effective monitoring of the slope.

[0046] according to Figures 3 to 6 As shown, the buried cylinder 3 has a fixed rod 7 inside. The outer end of the fixed rod 7 is rotatably connected to an upper notch plate 81 and a lower notch plate 82 distributed vertically. The upper notch plate 81 is located above the lower notch plate 82. A portion of the cross-seam rope 2 moves through the buried cylinder 3 and is located inside the notch of the upper notch plate 81. This portion of the cross-seam rope 2 is used to limit the upper notch plate 81 and restrict its rotation. Another portion of the cross-seam rope 2 moves through the buried cylinder 3 and is located inside the notch of the lower notch plate 82. This portion of the cross-seam rope 2 limits the lower notch plate 82 and restricts its rotation. The sides of both the upper notch plate 81 and the lower notch plate 82 are provided with arc-shaped grooves 801. A pair of sliding joints are fixedly connected to the inner wall of the buried cylinder 3. Block 301, a pair of sliders 301 are slidably connected inside a pair of arc-shaped grooves 801. The pair of sliders 301 are on the same vertical line, and the maximum rotation angle of the sliders 301 in the arc-shaped grooves 801 is 180°. Through the cooperation of the sliders 301 and the arc-shaped grooves 801, on the one hand, the upper notch 81 and the lower notch 82 can be positioned so that they can rotate horizontally and are not easy to move up and down. On the other hand, the rotation range and rotation direction of the upper notch 81 and the lower notch 82 can be controlled by the arc-shaped grooves 801 so that they can be smoothly aligned at the notch after rotation, which facilitates the emission of laser light 9 and realizes light warning.

[0047] Please see Figure 7 A pair of main magnetic blocks 10 are fixedly connected inside the fixed rod 7. The pair of main magnetic blocks 10 are located at the center of the upper missing disk 81 and the lower missing disk 82, respectively. A pair of auxiliary magnetic blocks 11 are fixedly connected to the inner walls of the upper missing disk 81 and the lower missing disk 82. The ends of the pair of auxiliary magnetic blocks 11 that are close to each other are opposite poles. Through the magnetic force between the main magnetic blocks 10 and the auxiliary magnetic blocks 11, the upper missing disk 81 and the lower missing disk 82 are in a stable state, that is, the pair of auxiliary magnetic blocks 11 and the middle main magnetic block 10 are opposite poles facing each other. Therefore, when no external force is applied to the upper missing disk 81 and the lower missing disk 82, the upper missing disk 81 and the lower missing disk 82 can be automatically rotated by the magnetic force until they rotate to the stable state.

[0048] Please see Figure 8A laser light 9 is fixedly connected to the inner bottom surface of the buried cylinder 3. The laser light 9 can be a laser lamp, which can be conveniently emitted from a long distance in the air to achieve a clear light warning effect. A light-transmitting sheet 4 is fixedly connected to the upper end of the buried cylinder 3. The upper end of the fixed rod 7 is fixedly connected to the lower end of the light-transmitting sheet 4. The light-transmitting sheet 4 is made of light-transmitting material, which does not easily affect the transmission of light from the laser light 9.

[0049] Please see Figure 5 The cross-seam rope 2 includes a rope body 21 fixedly connected to the embedded nail 1. A T-shaped stop 22 is fixedly connected to the end of the rope body 21 away from the embedded nail 1. The T-shaped stop 22 movably passes through the embedded cylinder 3 and is in an interference fit with its interior. The large friction between the two improves the stability of the T-shaped stop 22 inside the embedded cylinder 3. A magnetic piece 23 is fixedly connected to the end of the T-shaped stop 22 away from the rope body 21. Please refer to [link / reference]. Figure 7 Both the upper notch 81 and the lower notch 82 have a magnetically conductive layer 83 fixedly connected to their notch ends. The magnetic sheet 23 and the corresponding magnetically conductive layer 83 attract each other. The magnetically conductive layer 83 can be made of iron. The magnetic attraction between the two can further improve the stability of the cross-slit rope 2 in the buried cylinder 3, making it less likely for the cross-slit rope 2 to be easily moved out of the buried cylinder 3 under slight external force caused by non-landslide factors, and further improving the accuracy of the landslide monitoring results of this application.

[0050] Please see Figure 7 The lower end of the upper notch 81 has a cylindrical groove, and a positioning rod 12 is slidably connected inside the cylindrical groove. The upper end of the lower notch 82 has a positioning groove 802 that matches the positioning rod 12. The length of the positioning rod 12 is less than the depth of the cylindrical groove but greater than the depth of the positioning groove 802. The ratio of the diameter of the positioning groove 802 to the diameter of the positioning rod 12 is 2-3:1. Figure 10 As shown, when the positioning rod 12 is not aligned with the positioning groove 802, its lower end is located above the lower notch 82. When the upper notch 81 and the lower notch 82 rotate simultaneously, the positioning rod 12 will fall from the cylindrical groove into the positioning groove 802 when the two rotate to the notch alignment state, thus positioning the upper notch 81 and the lower notch 82 in this state. Even if the main magnetic block 10 and the auxiliary magnetic block 11 have not reached the stable state of opposite poles, the upper notch 81 and the lower notch 82 can be stopped from rotating and relatively stable, so that the light of the laser lamp 9 can be smoothly emitted from the notch of the two to achieve the light warning effect.

[0051] The lower end of the buried cylinder 3 is fixedly connected to a deep-buried cone 6, and the side end of the buried cylinder 3 is fixedly connected to a stabilizing airbag 5. The stabilizing airbag 5 is located between the deep-buried cone 6 and the cross-slit rope 2. When the buried cylinder 3 is installed into the crack, the deep-buried cone 6 penetrates into the crack, and the stabilizing airbag 5 is elastically deformed and squeezed into the crack, which makes the installation of the buried cylinder 3 more stable.

[0052] A geological loosening detection and early warning device for geological testing, the method of use of which is as follows:

[0053] S1, such as Figure 1 and Figure 2 As shown in the figure, M represents a crack. The buried cylinder 3 is installed in a crack of the slope, wherein: the part below the cross-crack rope 2 is located inside the crack, and the part above the cross-crack rope 2 is located on the upper side of the slope surface.

[0054] S2. Extend the multiple cross-crack ropes 2 located at the gap of the upper missing plate 81 and the multiple cross-crack ropes 2 located at the gap of the lower missing plate 82 along the slope surface upward and downward respectively, until the cross-crack ropes 2 are nearly straightened and the cross-crack ropes 2 span at least one crack.

[0055] like Figure 1 and Figure 2 As shown: In this embodiment, multiple cross-slit ropes 2 located at the gap of the upper notch 81 extend downward along the slope surface, and multiple cross-slit ropes 2 located at the gap of the lower notch 82 extend upward along the slope surface.

[0056] S3. Fix the embedded nail 1 to the slope with bolts to define the position of the cross-seam rope 2;

[0057] At this point, in the initial use state: the notches of the upper notch plate 81 and the lower notch plate 82 are located on both sides of the fixed rod 7, that is, there is no alignment or communication between the two notches. The light from the laser lamp 9 is blocked by the two and does not reach the outside. The positioning rod 12 and the positioning groove 802 are also located on both sides of the fixed rod 7. The two adjacent ends of the auxiliary magnetic block 11 and the main magnetic block 10 are the same pole, that is, there is magnetic repulsion between the two, and they are in an unstable magnetic force state. However, the upper notch plate 81 and the lower notch plate 82 cannot rotate under the limiting and blocking of the cross-seam rope 2, and are in a stable state.

[0058] S4. When the slope undergoes significant deformation and movement, part of the cross-joint rope 2 moves along with the sliding portion of the slope, causing the cross-joint rope 2 to separate from the buried cylinder 3. The upper notch plate 81 or the lower notch plate 82 rotates, aligning the notches of the two. The light emitted by the laser lamp 9 is emitted into the air through the notch and the light-transmitting plate 4, forming a light warning. The specific situation is as follows:

[0059] Scenario 1: When the crack where the buried cylinder 3 is located or the crack below it deforms, this part of the slope structure will cause the buried nail 1 at its upper end to move down the slope together. The cross-joint rope 2 connected to this part of the buried nail 1 will gradually be pulled. When the slope moves down to a certain extent, the buried nail 1 will cause the cross-joint rope 2 to detach from the buried cylinder 3, such as... Figure 9 As shown, after the T-shaped stop 22 loses its limiting function, under the magnetic force of the main magnetic block 10 and the auxiliary magnetic block 11, the upper notch disk 81 will rotate to a certain extent. When multiple cross-slit ropes 2 at the notch of the upper notch disk 81 move out of the buried cylinder 3 due to landslide, the upper notch disk 81 will rotate 180° until the magnetic force stabilizes, as shown. Figure 11As shown, at this time, the gaps of the upper missing plate 81 and the lower missing plate 82 are aligned, and the light from the laser light 9 will be emitted into the air through the pair of gaps to provide a light warning to the monitoring personnel.

[0060] Scenario 2: When the crack above the buried cylinder 3 deforms, the slope structure below the crack will cause the buried cylinder 3 and the buried nail 1 to move down the slope together. Meanwhile, the multiple buried nails 1 above the crack remain fixed on the slope. Therefore, when the slope moves down to a certain extent, as the buried cylinder 3 moves down, multiple cross-slit ropes 2 at the gap of the lower notch 82 will detach from the buried cylinder 3, causing the lower notch 82 to rotate 180° under the action of magnetic force, forming a gap alignment with the upper notch 81. The light from the laser lamp 9 will also be emitted into the air through this pair of gaps to provide a light warning to the monitoring personnel.

[0061] Scenario 3: When the cracks on the upper and lower sides of the buried cylinder 3 move downward to different degrees, that is, when the buried cylinder 3 and the buried nail 1 below it move asynchronously, the cross-slit ropes 2 at the gaps of the upper notch 81 and the lower notch 82 are both pulled. When the upper notch 81 and the lower notch 82 lose the restraint of the cross-slit ropes 2 and start to rotate, due to the cooperation of the arc groove 801 and the slider 301, the two rotate in opposite directions. Therefore, after the two rotate a certain angle, the positioning rod 12 just reaches the position of the positioning groove 802. Under its own weight, the positioning rod 12 enters the positioning groove 802, restricting the rotation of the upper notch 81 and the lower notch 82. At this time, the two gaps are just aligned, so that the light of the laser lamp 9 can pass smoothly through the pair of gaps and be emitted into the air to provide a light warning to the monitoring personnel.

[0062] S5. After the inspectors observed the light, they took precautions to prevent danger on the slope and recovered and reused the cross-slit rope 2 and the buried cylinder 3.

[0063] In step S5, when the buried cylinder 3 is used again, the magnetic conductive layer 83 can be attracted by the external magnet. That is, the magnetic attraction of the external magnet to the magnetic conductive layer 83 is greater than the magnetic attraction between the main magnetic block 10 and the auxiliary magnetic block 11, thereby guiding the rotated upper notch 81 or lower notch 82 back to its original position, so that the cross-seam rope 2 can be inserted into its notch.

[0064] By installing this application in a crack in the geological geology to be monitored, and extending it vertically along the geological surface, spanning multiple cracks, when the geology deforms and moves, the sliding part will cause the corresponding embedded nail 1 or embedded cylinder 3 to move downwards together, causing some of the cross-crack rope 2 to be pulled. When the geological deformation reaches the degree of movement, the cross-crack rope 2 will detach from the embedded cylinder 3, causing the unrestricted upper notch 81 or lower notch 82 to rotate automatically under the action of magnetic force until the upper notch 81 and lower notch 82 are aligned at the gap, so that the light from the laser lamp 9 can pass smoothly through the pair of gaps and be emitted into the air, providing the monitoring personnel with timely and effective long-distance light warning, enabling the monitoring personnel to take timely precautions against the geological geology with signs of impending disaster, and effectively reducing casualties.

[0065] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and its improved concept, should be covered within the scope of protection of this application.

A geological loosening detection and early warning device for geological testing according to claim 1, characterized in that, In the initial use state: the notches of the upper notch (81) and the lower notch (82) are located on both sides of the fixed rod (7), the positioning rod (12) and the positioning groove (802) are also located on both sides of the fixed rod (7), and the auxiliary magnetic block (11) and the main magnetic block (10) have the same pole at the end that is close to each other.

7. A geological loosening detection and early warning device for geological testing according to claim 1, characterized in that, The lower end of the buried cylinder (3) is fixedly connected to a deep-buried cone (6), and the side end of the buried cylinder (3) is fixedly connected to a stabilizing airbag (5). The stabilizing airbag (5) is located between the deep-buried cone (6) and the cross-seam rope (2).

8. A geological loosening detection and early warning device for geological testing according to claim 1, characterized in that, Its usage method is as follows: S1. Install the buried cylinder (3) in a crack in the slope, wherein: the part below the cross-slit rope (2) is located inside the crack, and the part above the cross-slit rope (2) is located on the upper side of the slope surface; S2. Extend the multiple cross-slit ropes (2) located at the gap of the upper missing plate (81) and the multiple cross-slit ropes (2) located at the gap of the lower missing plate (82) upward and downward along the slope surface respectively until the cross-slit ropes (2) are nearly straight and the cross-slit ropes (2) span at least one crack. S3. Fix the embedded nail (1) to the slope with bolts to define the position of the cross-seam rope (2); S4. When the slope undergoes significant deformation and movement, part of the cross-slit rope (2) moves along with the sliding part on the slope, causing the cross-slit rope (2) to separate from the buried cylinder (3). The upper notch (81) or the lower notch (82) rotates, causing the gaps of the two to align. The light emitted by the laser lamp (9) shines into the air through the gap and the light-transmitting sheet (4), forming a light warning. S5. After the inspectors observed the light, they took precautions against the danger on the slope and recycled and reused the cross-slit rope (2) and the buried cylinder (3).

9. A geological loosening detection and early warning device for geological testing according to claim 8, characterized in that, In step S5, when the buried cylinder (3) is used again, the magnetic conductive layer (83) can be attracted by an external magnet, thereby guiding the rotated upper notch (81) or lower notch (82) back to its original position, so that the cross-seam rope (2) can be inserted into its notch.
