[0002] Rock landslides, as a geological disaster phenomenon that seriously threatens the safety and development of mountainous areas, have extremely critical research significance in many fields such as transportation infrastructure construction, mining operations, and water conservancy and hydropower project layout. In recent years, with the continuous expansion of human activities and the intensification of the impact of climate change, the frequency and potential risks of rock landslides have continued to rise, making the need for in-depth research more urgent.

[0003] In the actual rock landslide process, vibration amplitude is one of the key factors. Under different vibration amplitudes, the degree and mode of rock damage are completely different, and the size, shape, and number of the falling stones also vary significantly. However, most of the existing simulation test devices fail to effectively collect the stones that slide down under different vibration amplitudes, which makes it impossible to deeply analyze the rich information contained in these stones, and it is difficult to accurately explore the inherent mechanism of rock damage caused by different vibration intensities and the force response of rock at each stage, which in turn affects the accuracy of the simulation experiment.

[0004] At the same time, rainfall also plays a vital role in the process of rock landslides. It can not only reduce the friction between rocks through lubrication, but also change the stress state of the rock through changes in pore pressure. However, most of the existing simulation devices are not convenient for classifying and collecting the content of stones and water in the landslide, and it is difficult to analyze the mechanical mechanism and movement characteristics of rock landslides under different stone and water content ratios.

At this time, the lower pressure plate 407 moves downward and squeezes the first triangular convex plate 404, driving the first sealing plate 403 to move in the first oil storage box 402, and the hydraulic oil in the first oil storage box 402 enters the second oil storage box 409 through the oil pipe 416, pushing the second sealing plate 414 to move.The squeezing plate 415 squeezes the second triangular convex plate 413. At this time, the second triangular convex plate 413 makes the filter frame 418 vibrate up and down through the conductive frame 419. The filter screen 420 in the filter frame 418 vibrates and drains the gravel in the classification box 301. The drained water flows into the liquid storage box 302 through the liquid hole 309 on the bottom surface of the classification box 301. The drawer 303 at the lower end of the liquid storage box 302 can conveniently take out the stored liquid, so as to analyze and study the drainage situation later. The vibration position of the experimental model 111, firstly, can accurately control the vibration amplitude of the experimental model 111, covering small, medium, large and other different amplitudes, can fully simulate the rock landslide process under various conditions, and at the same time, the landslide classification storage mechanism 3 can classify and collect the crushed stones that slide down with different vibrations, and can analyze the size and shape of the falling crushed stones in various vibration amplitudes, so that the staff can explore the influence of different vibration intensities on the degree and mode of rock damage, and understand the force response characteristics of rock at various stages. Secondly, in the vibration of the model storage mechanism 1 During the process, the vibration drainage mechanism 4 can be driven to work synchronously to ensure that the filter screen 420 is in a corresponding vibration state, effectively ensuring the stability of the gravel drainage inside the classification box 301, and at the same time, the water drained from the gravel can be collected and stored, so as to facilitate the staff to analyze the relationship between water content and rock characteristics, assist in determining the cause of landslides, and also facilitate the assessment of soil and water loss under different vibration amplitudes. Third, after the experiment, the cleaning door 306 can be opened automatically during the movement of the amplitude adjustment mechanism 2, without the need for manual operation by the staff, so that the staff can collect or clean the gravel in the classification box 301, which brings convenience to the actual use of the staff. Fourth, while regulating the vibration amplitude of the experimental model 111, the gravel sliding down at different vibration amplitudes can also be classified and collected. The vibration drainage mechanism 4 can also be driven according to the vibration amplitude of the experimental model 111, so that the filter frame 418 drains the collected gravel at the corresponding vibration frequency. After the experiment, it is convenient for the staff to clean or collect the gravel and drained water, which is convenient for the staff to actually use.

[0031] Specifically, the working principle of the high-position rock landslide simulation test device is as follows: first, the first servo motor 201 is started according to the type of simulation experiment. When the experimental model 111 needs to be vibrated with a medium amplitude, the first servo motor 201 drives the one-way screw 202 to rotate, so that the one-way slide 203 moves laterally. At this time, the one-way slide 203 drives the support frame 205, the amplitude adjustment seat 207, the small semi-arc adjustment plate 208, the middle semi-arc adjustment plate 209 and the large semi-arc adjustment plate 210 to move synchronously. When the middle semi-arc adjustment plate 209 and the corresponding lower amplitude adjustment seat 207 move to the top of the cam 213, the second servo motor 211 is started. At this time, the second servo motor 211 drives the rotating rod 212 to rotate, and the cam 213 on the rotating rod 212 is aligned with the corresponding The amplitude adjustment seat 207 cooperates with the amplitude adjustment seat 207. When the cam 213 rotates, the amplitude adjustment seat 207 drives the middle semi-arc adjustment plate 209 to cooperate with the lower surface of the placement plate 110 to change the amplitude of the placement plate 110. As the amplitude changes, the experimental model 111 produces different degrees of vibration, resulting in the sliding of gravel in the rock landslide. At this time, the amplitude adjustment mechanism 2 drives the middle semi-arc adjustment plate 209 to change the amplitude of the placement plate 110, and also makes the classification box 301 connected thereto move to the corresponding position synchronously. The sliding gravel will fall into the corresponding stone storage position of the classification box 301 according to the current amplitude. It is convenient for the staff to classify, count and analyze the distribution and quantity of gravel under different amplitude conditions, and clearly understand the effects of different vibration intensities on the rock landslide. The influence of the falling of gravel is convenient for comparing the difference of results under different experimental conditions, which is of great help to the study of the movement law of gravel in rock landslide. During the vibration of the model, if the spray is turned on to simulate the rainfall environment, the water in the water tank 104, under the action of the water pump 105, reaches the spray plate 108 through the liquid pipe 106 and the multi-way pipe 107, and sprays the experimental model 111. The water flow scours the experimental model 111, further promoting the falling of gravel and the formation of landslide, and also simulating the influence of rain on rock landslide. During the vibration of the model storage mechanism 1, the lower pressure plate 407 on the lower surface of the placement plate 110 will move synchronously with the amplitude of the placement plate 110. At this time, the lower pressure plate 407 moves downward and squeezes the first triangular convex plate 404, driving the first dense The sealing plate 403 moves in the first oil storage box 402, and the hydraulic oil in the first oil storage box 402 enters the second oil storage box 409 through the oil pipe 416, pushing the second sealing plate 414 to move, so that the extrusion plate 415 squeezes the second triangular convex plate 413. At this time, the second triangular convex plate 413 makes the filter frame 418 vibrate up and down through the conductive frame 419, and the filter screen 420 in the filter frame 418 vibrates and drains the gravel in the classification box 301. The drained water flows into the liquid storage box 302 through the liquid hole 309 on the bottom surface of the classification box 301. The drawer 303 at the lower end of the liquid storage box 302 can easily take out the stored liquid, so as to analyze and study the drainage situation. At the same time, when conducting a medium-amplitude vibration experiment on the experimental model 111, as the vibration continues,The condition of the stone particles sliding down on the surface of the experimental model 111 will change accordingly according to the vibration amplitude. At this time, the lower pressure plate 407 moves up and down synchronously with the vibration amplitude of the placement plate 110. Because it is a medium-amplitude vibration, the stroke of the lower pressure plate 407 pressing the first triangular convex plate 404 downward is only half, thereby driving the filter frame 418 to produce a medium-amplitude vibration adapted thereto, ensuring that the filter screen 420 is in an ideal state when processing gravel drainage, which not only avoids excessive bouncing of gravel due to excessive amplitude, exceeding the effective filtering area of ​​the filter screen 420, resulting in incomplete drainage or even the chaos of gravel splashing everywhere, but also prevents the gravel from accumulating in large quantities on the filter screen 420 due to too small amplitude and being unable to be fully turned over, ultimately leading to the undesirable situation of seriously low drainage efficiency and a large amount of residual water, thereby effectively improving the accuracy and effectiveness of the drainage process. When it is necessary to vibrate the experimental model 111 with different amplitudes, such as small or large amplitude vibrations, it is only necessary to adjust the unidirectional slide plate 203 through the first servo motor 201. position, so that the small semi-arc adjustment plate 208 or the large semi-arc adjustment plate 210 moves to the top of the cam 213, and the above corresponding operations are repeated, thereby comprehensively simulating the rock landslide process under different conditions, and classifying, collecting, analyzing and studying the gravel and related conditions generated therefrom. Finally, when the experiment is completed and the gravel inside the classification box 301 needs to be cleaned, the first servo motor 201 is started again to make the one-way slide plate 203 drive the classification box 301 to move to the rear end of the support seat 102. At this time, the cleaning door 306 will be opened to the outside of the classification box 301 under the action of the support spring 305. The positioning plate 307 is continuously limited by the positioning bar 308 during the movement, thereby limiting the opening angle of the cleaning door 306, so that the cleaning door 306 can be reset again during the resetting process of the classification box 301, thereby not affecting the normal use of the equipment. By opening the cleaning door 306, the gravel inside the classification box 301 can be easily cleaned, which brings convenience to the actual use of the staff.
