Description

Technical Field

[0001] The invention relates to a simulation test technology, and in particular to a rock slope fissure water seepage test simulation device. Background Art

[0002] With the progress of society, the construction of ecological civilization has also entered a new stage of in-depth development. However, in the past, large-scale excavation of rock slopes in open-pit mining and highway construction destroyed the aquifer structure of the slope, leading to vegetation degradation and biodiversity loss, and also caused the occurrence of serious geological disasters such as collapse, landslides, and mudslides. In particular, landslide hazards are one of the most common geological disasters, and their generation mechanism is complex. In the rock slopes of sandstone interlayers, when the rear edge cracks develop, rainfall infiltrates through the cracks and forms a water column at the rear edge, threatening the stability of the slope. At the same time, rainwater seeps downward along the weak interlayer, softening the mudstone layer and reducing its shear resistance. When the anti-sliding force of the weak surface is less than the sliding force, the upper slope undergoes translational shear failure and forms a landslide. Therefore, how to scientifically and rationally utilize rock slope resources and achieve harmonious coexistence between the slope geological environment and the ecosystem is an important issue that needs to be solved urgently.

[0003] A Chinese invention patent with publication number CN220339996U discloses a rock slope fissure water seepage test simulation device. The rock slope fissure water seepage test simulation device can simulate the complex fissure system and liquid seepage direction inside the rock slope by setting a rock slope model, staggered first and second fissures, and connected water outlets and drainage pipes. On the basis of controlling the water head conditions of the water source, the process from infiltration to discharge of the fissure liquid is completely simulated, and parameters such as the seepage time and the seepage amount at different parts are statistically analyzed. The water pressure and the shape and number of the fissures are adjusted to study their influence on the seepage. In this way, a large amount of quantitative data can be obtained, and the seepage law of the fissure liquid inside the rock slope is scientifically revealed, providing an important basis for related rock slope hydrogeological research and slope stability assessment.

[0004] When existing equipment is used, the groundwater inflow in the simulated state may show different permeability characteristics, which makes it impossible to control the water flow rate and injection depth, resulting in poor overall effect when simulating the penetration of different groundwater flows. At the same time, during the simulation process, it is impossible to switch the input priority and flow rate according to experimental needs. Therefore, a rock slope fissure water seepage test simulation device was developed. Summary of the invention

[0039] Specifically, the guide groove 12 is divided by the swing block 13, and the guide groove 12 located behind the swing block 13 is divided into two directions, thereby simulating the seepage condition of the rock slope fissure after the water flows at different positions.

[0040] The driving member 15 is a device with power output such as a motor, and is connected to an external control device. When the driving member 15 is started, it synchronously drives the positioning shaft 14 arranged at its end to rotate. Since the swing block 13 is connected to the positioning shaft 14, it also drives the swing block 13 to rotate, thereby adjusting the direction of the water flow.

[0045] Specifically, when the connecting block 34 moves, it synchronously drives the extension rod 341 installed on its outer surface to move. Since the end of the extension rod 341 is rotationally connected to the outer surface of the limit block 36, the limit block 36 moves synchronously with the extension rod 341. At the same time, the limit block 36 is limited by the through hole 321 to ensure the stability of the limit block 36.

[0046] Furthermore, the inner wall of the sleeve 32 is provided with a locking block 37 corresponding to the limit block 36, the end of the locking block 37 is rotatably connected to the outer surface of the limit block 36, the end of the limit block 36 is provided with an extrusion rod 39, the end of the extrusion rod 39 is provided with a pressing block 391, and at the same time, a sphere 392 is slidably installed on the outer surface of the pressing block 391, and the outer surface of the sphere 392 is in contact with the inner wall of the conveying pipe 11.

[0047] Specifically, the limiting block 36 is limited by the locking block 37 , so that when the limiting block 36 rotates around the locking block 37 , the overall stability of the limiting block 36 is ensured.

[0048] Since the extrusion rod 39 is connected to the end of the limit block 36 , the extrusion rod 39 moves synchronously with the limit block 36 , and drives the ball 392 to move left and right through the pressing block 391 .

[0049] The outer surface of the ball 392 is provided with a driving groove, and the inner wall of the driving groove is slidably connected to the outer surface of the pressing block 391.

The cross section of the delivery tube 11 is tapered.

[0050] Furthermore, a second elastic member 38 is sleeved on the outer surface of the fixing column 35 , and one end of the second elastic member 38 is connected to the connecting block 34 , and the other end is connected to the inner wall of the sleeve 32 .

[0051] Specifically, the second elastic member 38 is an elastic member such as a spring, and the connecting block 34 is supported by the second elastic member 38 , thereby ensuring the stability of the connecting block 34 .

[0052] Furthermore, the positioning assembly 2 is assembled at the lower end of the base 1, and the adjusted swing block 13 is locked by the positioning assembly 2. The positioning assembly 2 includes a bottom plate 21 connected to the base 1, a support member 22 is provided at the end of the bottom plate 21, and a guide block 23 is symmetrically provided at the end of the bottom plate 21.

[0054] Furthermore, a movable block 25 is symmetrically slidably mounted on the inner wall of the slide groove 241 , and a positioning block 27 is rotatably mounted on the end of the movable block 25 .

[0055] Specifically, the movable block 25 is limited by the slide groove 241, so that when the push block 24 moves, the movable block 25 is driven to move synchronously.

[0056] Furthermore, the two positioning blocks 27 are rotatably connected at opposite ends, and the rotatably connected ends are connected to the ends of the bottom plate 21. A positioning rod 26 is rotatably mounted on the outer surface of the movable block 25, and a driving rod 28 is disposed at one end of the positioning rod 26 away from the push block 24.

[0057] Specifically, when the movable block 25 moves, it rotates around the connection between the two positioning blocks 27 and moves in coordination with the positioning rod 26 and the driving rod 28 , thereby fixing the positioning shaft 14 and ensuring the stability of the positioning shaft 14 .

[0058] Furthermore, a movable groove 281 is provided at the end of the driving rod 28, and the inner wall of the movable groove 281 is slidably connected to the outer surface of the positioning rod 26.

[0060] The first elastic member 291 is an elastic component such as a spring, which is used to support the clamping block 29 so as to ensure the stability of the clamping block 29 when the clamping block 29 is supported by the positioning shaft 14 .

[0061] The control device can select a single-chip microcomputer as the control end. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (MicrocontrollerUnit), which is composed of an arithmetic unit, a controller, a memory, an input and output device, etc., which is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware) and cost saving. Its biggest advantage is that it is small in size and can be placed inside the instrument, but the storage capacity is small, the input and output interface is simple, and the function consumption is low.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
