Description

Technical Field

[0001] This invention relates to the field of landslide surge, and in particular to a high-level landslide motion speed control device and method based on the characteristics of 3D-printed slip zones. Background Technology

[0002] Landslide surges, a secondary disaster resulting from landslide instability and sliding into water, cause damage far exceeding that of the landslide itself, often resulting in numerous casualties, economic losses, and even catastrophic consequences. For example, in 1963, the instability of the soil and rock mass near the dam on the left bank of the Vajont Reservoir in Italy caused a surge that resulted in the deaths of more than 2,000 people.

[0003] In recent years, with the construction of numerous high dams and reservoirs hundreds of meters high in my country, the hydrogeological environment and stress field of the riverbanks within the reservoir areas have undergone drastic changes, leading to frequent landslide and surge disasters. Currently, due to the differences in initial conditions, boundary conditions, calculation parameters, and surge propagation models among various landslides, it is difficult to accurately grasp the full-process characteristics of landslide and surge disasters. Therefore, the problem of high-risk, high-level landslides and surges in high dams and reservoirs has become a critical engineering and scientific problem that urgently needs to be solved.

[0004] The landslide entry velocity into water is a prerequisite for surge analysis and is particularly important throughout the entire landslide motion evolution process. It is a key variable that needs to be accurately controlled in physical model tests.

[0005] Numerous factors influence landslide velocity, such as landslide center of mass height, instability volume, sliding direction, slip surface angle, and slip surface morphology. Currently, the main methods for studying landslide velocity include theoretical analysis, model tests, and numerical simulations. Among these, physical model tests are the most reliable and intuitive method; however, they are limited by the model scale, resulting in high cost and operational difficulty. Furthermore, these physical models have the following shortcomings:

[0006] (1) There are few existing physical models that consider high-risk, high-altitude landslide simulation devices. These landslide simulation devices are high in height, have long sliding tracks, and require a certain initial velocity to be provided to the sliding body.

[0007] (2) When using existing landslide simulation devices, the slope angle is increased so that the landslide body slides into the water under its own weight, which makes it impossible to accurately control the sliding speed of the landslide body during the sliding process;

[0008] (3) Existing landslide simulation devices ignore the influence of the sliding surface morphology on the landslide velocity. Many landslide simulation devices simplify the sliding surface into a smooth slope or curved surface, which does not match the real terrain.

[0009] (4) Due to the large volume of the landslide body, the loading and unloading operations during the landslide simulation test are complicated and time-consuming and labor-intensive if only manual operation is used. Summary of the Invention

[0010] The main objective of this invention is to propose a high-level landslide motion speed control device and method based on the characteristics of 3D printed slip surfaces. This aims to solve the problem that existing landslide simulation devices cannot accurately control the speed of the sliding body and do not consider the influence of slip surface morphology on landslide speed. As a result, the experimental results obtained deviate significantly from the actual situation, which affects the study of landslide surge.

[0011] To address the aforementioned issues, this invention proposes a high-level landslide motion speed control device and method based on the characteristics of a 3D-printed sliding strip. The device includes a landslide inclination adjustment device and a landslide occurrence simulation device, a landslide speed adjustment device, a sliding plate, and an overlapping plate mounted on the landslide inclination adjustment device. One end of the overlapping plate overlaps with the landslide occurrence simulation device, and the other end overlaps with the landslide speed adjustment device. The end of the landslide speed adjustment device furthest from the overlapping plate overlaps with the sliding plate.

[0012] The landslide simulation device is equipped with a sliding body, which can simulate the occurrence of a landslide. The sliding body slides from the landslide simulation device into the landslide speed adjustment device with the help of an overlapping plate. The landslide speed adjustment device adjusts the sliding speed of the sliding body. After adjustment, the sliding body slides into the sliding plate and then slides into the water.

[0013] The landslide tilt angle adjustment device is used to adjust the tilt angle of the landslide occurrence simulation device, the landslide speed adjustment device, the sliding plate, and the overlapping plate.

[0016] Place the sliding body on the 3D-printed terrain and allow it to slide down along with the 3D-printed terrain;

[0028] One end of the overlapping plate is hinged to the sliding box, and the other end overlaps on the landslide speed adjustment device. The upper surface of the 3D printed terrain and the upper surface of the overlapping plate are smoothly connected.

[0029] In one embodiment, the mounting plate is provided with a sliding groove for the sliding box to slide, and a stop block is fixed in the sliding groove at one end near the landslide speed adjustment device to prevent the sliding box from sliding.

[0030] In one embodiment, a baffle is detachably fixed to the sliding box, and one end of the overlapping plate is hinged to the upper edge of the baffle.

[0031] In one embodiment, the landslide speed regulating device includes:

[0032] A belt conveyor is mounted on slide rail two. The other end of the overlapping plate overlaps the upward-sloping end of the conveyor belt of the belt conveyor, and the upward-sloping end of the sliding plate is located below the downward-sloping end of the conveyor belt.

[0033] A speed sensor, installed on a belt conveyor, is used to detect the moving speed of the conveyor belt.

[0037] A speed sensor, installed on a belt conveyor, is used to detect the moving speed of the conveyor belt;

[0038] The other end of the overlapping plate overlaps the upward-sloping end of the conveyor belt of the belt conveyor, and the upward-sloping end of the sliding plate is located below the downward-sloping end of the conveyor belt.

[0059] This invention proposes a high-level landslide motion speed control device based on the characteristics of a 3D-printed slip surface. This device uses 3D printing technology to print a slip surface that conforms to the actual terrain for the sliding body 16 to slide on. It fully considers the influence of the slip surface morphology on the sliding speed of the sliding body 16. At the same time, it uses a landslide speed adjustment device 2 to precisely control the sliding speed of the sliding body 16. With this design, the experimental results obtained are close to the actual situation, which is very helpful for the correct study of landslide surge.

[0060] Specifically, in one embodiment of the invention, such as Figure 1 As shown, the high-level landslide motion speed control device based on the characteristics of 3D printed slip zones includes a landslide inclination adjustment device 4 and a landslide occurrence simulation device 1, a landslide speed adjustment device 2, a sliding plate 3, and an overlapping plate 19 mounted on the landslide inclination adjustment device 4. One end of the overlapping plate 19 overlaps with the landslide occurrence simulation device 1, and the other end overlaps with the landslide speed adjustment device 2. The end of the landslide speed adjustment device 2 away from the overlapping plate 19 overlaps with the sliding plate 3. The landslide occurrence simulation device 1 is equipped with a sliding body 16, and the landslide occurrence simulation device 1 can simulate a sliding body. When a landslide occurs, the sliding body 16 slides from the landslide simulation device 1 into the landslide speed adjustment device 2 via the connecting plate 19. The landslide speed adjustment device 2 adjusts the sliding speed of the sliding body 16. After adjustment, the sliding body 16 slides into the sliding plate 3 and continues to slide down, eventually sliding into the water from the sliding plate 3. The landslide inclination angle adjustment device 4 is used to adjust the inclination angle of the landslide simulation device 1, the landslide speed adjustment device 2, the sliding plate 3, and the connecting plate 19, that is, to adjust the inclination angle of the sliding surface of the sliding body 16 so as to meet the requirements of landslide tests under different simulated environments.

[0061] In this embodiment, as Figure 1 and Figure 4As shown, the landslide tilt angle adjustment device 4 includes a first slide rail 41 and a second slide rail 47 located above the first slide rail 41. The first slide rail 41 and the second slide rail 47 are connected by a first support rod 46 and a second support rod 45. The lower end of the first support rod 46 is fixedly connected to the first slide rail 41, and the upper end of the first support rod 46 is hinged to the second slide rail 47. This design facilitates the adjustment of the second slide rail 47 so that it can rotate around the upper end of the first support rod 46 to adjust the tilt angle of the second slide rail 47, that is, to adjust the tilt angle of the sliding surface of the landslide body 16. This solves the problems of existing landslide models having a single slope and fixed slope height, which cannot be adjusted and changed, and makes it meet the requirements of landslide tests under different simulation environments.

[0062] In this embodiment, as Figure 1 and Figure 4 As shown, the lower end of the second support rod 45 is slidably connected to the first slide rail 41, and the upper end of the second support rod 45 is slidably connected to the second slide rail 47. The lengths of the first support rod 46 and the second support rod 45 are not equal. Preferably, the length of the second support rod 45 is greater than the length of the first support rod 46. This design, as shown... Figure 4 As shown, pushing the second support rod 45 along the first slide rail 41 can adjust the tilt angle of the second slide rail 47, that is, adjust the sliding surface tilt angle of the slide body 16 to meet the landslide test requirements under different simulated environments.

[0063] In this embodiment, as Figure 1 As shown, the landslide simulation device 1 and the slide plate 3 are fixed on the slide rail 47. Therefore, adjusting the tilt angle of the slide rail 47 is to adjust the sliding surface tilt angle of the slide body 16 so as to meet the landslide test requirements under different simulation environments.

[0064] Furthermore, in this embodiment, as Figure 4 As shown, a slider 42 is slidably mounted on the slide rail 41. A push-pull device 44 and a lifting device 43 are fixedly mounted on the slider 42. The push-pull device 44 is horizontally arranged, with one end fixedly connected to the lower end of the support rod 46, and is used to pull the slider 42 to slide on the slide rail 41, thereby adjusting the tilt angle of the slide rail 47. The lifting device 43 is vertically arranged, with its upper end fixedly connected to the lower end of the support rod 45, and is used to lift the support rod 45, so as to adjust the tilt angle of the slide rail 47 to a larger range, further expanding the application range of the high-level landslide motion speed control device based on the 3D printed sliding surface feature, making it suitable for more landslide simulation environment tests.

[0065] Preferably, the push-pull device 44 and the lifting device 43 can be pneumatic cylinders, hydraulic cylinders or linear motors.

[0066] In this embodiment, as Figure 1 and Figure 2As shown, the landslide simulation device 1 includes a mounting plate 11 and a sliding box 13, as... Figure 1 As shown, the mounting plate 11 is fixedly connected to the slide rail 47, and the sliding box 13 is slidably mounted on the mounting plate 11 along the inclined direction of the slide rail 47. Furthermore, to enhance the stability of the sliding box 13 sliding downwards on the mounting plate 11, as follows... Figure 2 As shown, the mounting plate 11 is provided with a sliding groove 12 for the sliding box 13 to slide.

[0067] In this embodiment, as Figure 1 and Figure 2 As shown, a 3D-printed terrain 17 is fixed inside the sliding box 13. The 3D-printed terrain 17 is printed using 3D printing technology to proportionally reduce the size of a real slope to obtain a simulated slope that is close to the real slope. The sliding body 16 is placed on the 3D-printed terrain 17. With this design, the sliding body 16 slides obliquely downward on the 3D-printed terrain 17, which is very close to the actual situation. The influence of the sliding surface shape on the sliding speed of the sliding body 16 is fully considered. The experimental results obtained are real, accurate, and close to the actual situation, which is very helpful for the correct study of landslide surge.

[0068] In this embodiment, as Figure 1 and Figure 2 As shown, a stop 15 is fixed at one end of the chute 12 near the landslide speed adjustment device 2 to prevent the sliding box 13 from sliding. During operation, the sliding box 13 slides diagonally downward from the high end of the mounting plate 11. During this process, the sliding body 16 slides together with the 3D printed terrain 17. When the sliding box 13 approaches the landslide speed adjustment device 2, the stop 15 blocks the sliding box 13, preventing the sliding box 13 and the 3D printed terrain 17 from continuing to slide down. At this time, under the action of inertia, the sliding body 16 continues to slide diagonally downward on the 3D printed terrain 17.

[0069] In this embodiment, as Figure 1 and Figure 2 As shown, one end of the overlapping plate 19 is hinged to the sliding box 13, and the other end overlaps the landslide speed regulating device 2. This design... Figure 1 When the stop block 15 blocks the sliding box 13, the overlapping plate 19 will rotate downward around the end that is hinged to the sliding box 13 by means of inertia until the other end of the overlapping plate 19 overlaps the landslide speed regulating device 2.

[0070] In this embodiment, the upper surface of the 3D printed terrain 17 and the upper surface of the overlapping plate 19 are smoothly connected. With this design, after the block 15 blocks the sliding box 13, the sliding body 16 can continue to slide diagonally downward on the 3D printed terrain 17 and smoothly slide onto the overlapping plate 19, and then continue to slide diagonally downward on the overlapping plate 19 to the landslide speed adjustment device 2.

[0071] In this embodiment, to facilitate the assembly and disassembly of the 3D-printed terrain 17, such as Figure 2 As shown, a baffle 18 is detachably fixed on the sliding box 13. The 3D printed terrain 17 enters the sliding box 13 from the position of the baffle 18, and then the baffle 18 is installed. Although the upper end of the sliding box 13 is designed to be open, in order to prevent the 3D printed terrain 17 from flying off the sliding box 13 from the opening when the baffle 15 blocks the sliding box 13, the opening size is usually designed to be small. As a result, it will be very troublesome, time-consuming and laborious to install the 3D printed terrain 17 into the sliding box 13 from the opening, and it will be inconvenient to disassemble and assemble.

[0072] Correspondingly, such as Figure 2 As shown, one end of the overlapping plate 19 is hinged to the upper edge of the baffle 18. At this time, the downward-sloping end of the 3D printed terrain 17 is flush with the upper surface of the baffle 18. This design ensures that the upper surface of the 3D printed terrain 17 and the upper surface of the overlapping plate 19 are smoothly connected.

[0073] It is important to note that Figure 1 and Figure 2 To facilitate a comprehensive display of the internal structure of the sliding box 13, the 3D printed terrain 17 was not installed inside the sliding box 13.

[0074] Furthermore, in this embodiment, as Figure 2 As shown, the upper end of the sliding box 13 is connected to the hook 14. After one simulated landslide test is completed, the hook 14 is pulled to move the sliding box 13 upward and reset it so that the next simulated landslide test can be carried out. When the sliding box 13 has a large mass and requires a large traction force, the design of the hook 14 makes it convenient for external traction equipment to be connected to the sliding box 13. After the test, the sliding box 13 is lifted back to the original elevation position along the slide chute 12 by the traction equipment. This solves the problem of complicated loading and unloading operations caused by the large volume of the sliding box 13 during the test, facilitates repeated tests, and improves test efficiency.

[0075] The high-level landslide motion speed control device based on the 3D printed sliding surface features in this embodiment uses 3D printing technology to print the slope surface proportionally and fix it in the sliding box, so that it slides down together with the simulated sliding body 16, and fully considers the influence of the accumulation shape and sliding surface shape of the sliding body 16 on the sliding speed.

[0076] In this embodiment, the landslide speed regulating device 2 includes a belt conveyor 22 and a speed sensor 23. The belt conveyor 22 can be directly mounted on the slide rail 47, or it can be... Figure 1 and Figure 3As shown, it is independent of the slide rail 247, that is, it is set on the lifting platform 25. At this time, the landslide speed adjustment device 2 also includes the lifting platform 25 and the lifting device 24 set on the lifting platform 25. The height and tilt angle of the belt conveyor 22 can be adjusted by the lifting platform 25 and the lifting device 24 to adapt to various slide rails 24 with different heights and tilt angles, thus expanding the application range of the landslide speed adjustment device 2.

[0077] In this embodiment, as Figure 1 and Figure 3 As shown, one end of the belt conveyor 22 is hinged to the lifting platform 25, and the other end is connected to the lifting device 24. The lifting device 24 pushes the other end of the belt conveyor 22 to rotate around one end to adjust the tilt angle of the belt conveyor 22. The speed sensor 23 is installed on the belt conveyor 22 to detect the moving speed of the conveyor belt, and then feeds the detection data back to the computer (not shown in the figure). The computer adjusts the speed of the belt conveyor 22 according to the test situation, and finally adjusts the speed of the slider 42 to the correct position to meet the requirements of different sliding speeds of the sliding body 16 in different simulated landslide tests.

[0078] In this embodiment, as Figure 1 As shown, the other end of the overlapping plate 19 overlaps the obliquely upward end of the conveyor belt of the belt conveyor 22. With this design, the sliding body 16 can continue to slide obliquely downward on the overlapping plate 19 and smoothly slide onto the conveyor belt. Then, the belt conveyor 22 adjusts the sliding speed of the sliding body 16 so that it enters the water at a set speed.

[0079] Furthermore, in this embodiment, when the landslide simulation test requires the sliding body 16 to be made of other materials, in order to ensure that there is still good friction between the sliding body 16 and the conveyor belt and to ensure that the belt conveyor 22 can smoothly adjust the sliding speed of the sliding body 16, a conveyor belt with different roughness can be replaced.

[0080] In this embodiment, as Figure 1 As shown, the upward-sloping end of the slide plate 3 is located below the downward-sloping end of the conveyor belt. This design ensures that the slide body 16 on the conveyor belt can smoothly slide onto the slide plate 3 and finally slide into the water from the downward-sloping end of the slide plate 3.

[0081] Furthermore, to prevent the slide body 16 from slipping off the sides of the slide plate 3, such as... Figure 1 and Figure 4 As shown, baffles 31 are fixed on both sides of the slide plate 3.

[0082] In this embodiment, as Figure 1As shown, the high-level landslide motion speed control device based on 3D printed slip zone features also includes a laser velocimeter 5 and a high-speed camera 6. The laser velocimeter 5 is used to measure the entry speed of the landslide body 16 into the water, and the high-speed camera 6 is used to capture the entry image of the landslide body 16 into the water. By analyzing the slip velocity data measured by the laser velocimeter 5 and the real-time status photos captured by the high-speed camera 6, the motion law and velocity vector diagram of the landslide body 16 can be accurately captured. The detection data of the landslide body 16 is transmitted to the computer for analysis and processing, providing data reference for staff to study landslide surge waves.

[0083] The high-level landslide motion speed control device based on 3D printed slip surface features in this embodiment uses 3D printed terrain 17, fully considers the influence of landslide surface morphology on the sliding speed of sliding body 16, and accurately controls the slip surface inclination angle and the entry speed of sliding body 16 into the water. It has the characteristics of simple installation process, strong operability, convenient movement, convenient repeated testing, and high testing efficiency.

[0084] Furthermore, this invention also proposes a method for controlling the velocity of high-altitude landslides based on the characteristics of 3D-printed slip zones, comprising:

[0085] S1. Adjust the slope angle of the sliding surface when the sliding body 16 landslides. This step can be completed with the help of the landslide slope adjustment device 4. The sliding surface is adjusted to the predetermined slope by the landslide slope adjustment device 4.

[0086] S2. Place the sliding body 16 on the 3D printed terrain 17 and allow it to slide down together with the 3D printed terrain 17;

[0087] S3, the stop block 15 prevents the 3D printed terrain 17 from sliding. Under the action of inertia, the sliding body 16 slides from the 3D printed terrain 17 onto the conveyor belt of the landslide speed regulating device 2 with the help of the overlapping plate 19.

[0088] S4. The speed of the sliding body 16 is adjusted to the set speed by means of the belt conveyor 22 on the landslide speed regulating device 2;

[0089] S5, the sliding body 16 slides from the landslide speed regulating device 2 into the slide plate 3, and continues to slide down the slide plate 3 until it finally slides into the water;

[0090] S6. Using a laser velocimeter 5 and a high-speed camera 6, the entry speed of the sliding body 16 into the water is detected and the entry image of the sliding body 16 is obtained. By analyzing the sliding speed data measured by the laser velocimeter 5 and the real-time status photos taken by the high-speed camera 6, the motion law and velocity vector diagram of the sliding body 16 can be accurately captured, providing data reference for staff to study landslide surge.

[0091] In this embodiment, if the belt conveyor 22 is not directly installed on the slide rail 2 47, the tilt angle and height of the belt conveyor 22 need to be adjusted by the lifting platform 25 and the lifting device 24 to make it compatible with the height and tilt angle of the slide rail 2 47.

[0092] In this embodiment, a method for controlling the velocity of high-altitude landslides based on the characteristics of 3D-printed slip zones further includes:

[0093] S7. Analyze experimental data using computers;

[0094] S8. Using a traction device and hook 14, lift the sliding box 13 to its original elevation position and repeat the test. Multiple tests can improve the accuracy of the test and make the test results closer to the real situation, which helps to correctly study landslide surge.

Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
