Description

Technical Field

[0001] This utility model relates to the field of simulation experiment technology, specifically a debris flow dynamics simulation device. Background Technology

[0002] The debris flow dynamic physics simulation device is an important tool for reproducing the movement process of debris flows through laboratory experiments. It analyzes the dynamic characteristics such as flow velocity, flow rate, impact force, and accumulation range, and is used to verify theoretical models, study dynamic mechanisms, and optimize the design of prevention and control engineering.

In common experimental simulation devices, the ramps are usually set at a fixed angle, and the height of the storage container for the debris flow simulation mud is also fixed. This makes it inconvenient to adjust the flow angle and fall height of debris flow in real time during the simulation experiment, reducing the applicability of the experimental device.

Detailed Implementation

[0047] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0048] This application provides a debris flow dynamic simulation device that solves the problem of inconvenient adjustment of simulation experiment parameters. It achieves vertical movement of the connecting rod 42 via the operation of the hydraulic cylinder 41, causing the connecting column 45 to press against the inner wall of the connecting groove 44, pushing the connecting block 43 and the simulated track 31. This causes the simulated track 31 to rotate around the fixed axis 33, allowing adjustment of the angle of the simulated track 31 to regulate the debris flow angle. Furthermore, as the simulated track 31 rotates, the fixed column 46 pushes upward against the pressing block 48 and the fixed rod 47, thereby pushing the storage bin 36 upward and adjusting its height to align it with the simulated track 31. Simultaneously, the sliding block 410 and the storage bin 36 move vertically along the positioning rod 411, and the positioning bolt 413 is rotated and tightened so that one end is inserted into one of the positioning holes 412, fixing the storage bin 36 and facilitating height adjustment, thus enabling regulation of the debris flow's falling height.

[0049] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0050] This utility model discloses a debris flow dynamics simulation device.

[0051] According to the appendix Figure 1-5As shown, the device includes a test platform 1, a enclosure 2, a test mechanism 3, and an adjustment mechanism 4. The enclosure 2 is fixedly connected to the upper surface of the test platform 1 and is used to prevent the debris flow simulation material from splashing. The test mechanism 3 is set on the test platform 1 and is used to simulate debris flow experiments. The adjustment mechanism 4 is set on the test mechanism 3 and is used to adjust the test mechanism 3. The angle and height of the test mechanism 3 can be adjusted using the adjustment mechanism 4 to facilitate the simulation experiment of debris flow dynamics.

[0052] Specifically, the testing mechanism 3 includes a simulated track 31, a fixed block 32, a fixed shaft 33, a fixed seat 34, a support frame 35, a storage bin 36, a solenoid valve 37, and a pressure sensor 38. The simulated track 31 is set on the upper surface of the testing platform 1 and is inclined. The simulated debris flow passes through the simulated track 31 to simulate the debris flow dynamics. The fixed block 32 is fixedly connected to both sides of the lower surface of the simulated track 31 and is used to install the simulated track 31. The fixed shaft 33 is fixedly connected to one side of the fixed block 32. The fixed seat 34 is fixedly connected to the upper surface of the testing platform 1 and is rotatably connected to the fixed shaft 33. The simulated track 31 is rotatably connected to the fixed seat 34 through the fixed block 32 and the fixed shaft 33, which facilitates the adjustment of the angle of the simulated track 31. The support frame 35 is fixedly connected to the upper surface of the testing platform 1. On the test platform 1, two support frames 35 are symmetrically arranged on both sides of the upper surface for mounting storage bins 36. The storage bins 36 are slidably inserted between the support frames 35 and are positioned above one end of the simulation track 31. The storage bins 36 are used to store mud for the debris flow simulation experiment. The bottom of the storage bins 36 is funnel-shaped, and the mud in the storage bins 36 falls downward into the simulation track 31. A solenoid valve 37 is fixedly installed at the bottom of the storage bins 36. Pressure sensors 38 are fixedly installed on both sides of the simulation track 31 to detect the dynamics of the debris flow. The solenoid valve 37 is used to control the opening and closing of the bottom pipe of the storage bins 36. By opening the solenoid valve 37, the mud in the storage bins 36 is discharged downward and enters the simulation track 31. The mud in the debris flow simulation experiment flows downward along the simulation track 31 to simulate the dynamics of the debris flow.

[0053] Furthermore, the adjustment mechanism 4 includes a hydraulic cylinder 41, a connecting rod 42, a connecting block 43, a connecting groove 44, a connecting column 45, a fixed column 46, a fixed rod 47, a pressing block 48, a sliding groove 49, a sliding block 410, a positioning rod 411, a positioning hole 412, and a positioning bolt 413. The hydraulic cylinder 41 is fixedly installed inside the test platform 1 and is electrically connected to an external power supply via an external switch to drive the simulated track 31 to rotate. The connecting rod 42 is drivenly connected to the output end of the hydraulic cylinder 41 and is slidably interlocked with the test platform 1. The connecting rod 42 is used to connect the hydraulic cylinder 41 and the simulated track 31. As the hydraulic cylinder 41 operates, it drives the connecting rod 42 to move vertically. The connecting block 43 is fixedly connected to the middle of the lower surface of the simulated track 31. The connecting block 43 moves together with the simulated track 31 and is used to connect the simulated track 31 and the connecting rod 42. A connecting groove 44 is formed on the connecting block 43. The connecting groove 44 is elongated and is used to install the connecting column 45. The connecting column 45 is fixedly connected to the top of the connecting rod 42. The connecting column 45 is slidably inserted into the connecting groove 44. The connecting column 45 moves vertically with the connecting rod 42, slides in the connecting groove 44, and presses against the inner wall of the connecting groove 44, causing the connecting block 43 and the simulated track 31 to rotate. A fixing column 46 is fixedly connected to one side of the outer wall of the simulated track 31. The fixed column 46 moves together with the simulated track 31 to push the extrusion block 48 upward; the fixed rod 47 is fixedly connected to one side of the lower surface of the storage bin 36, and is used to push the storage bin 36 vertically upward; the extrusion block 48 is fixedly connected to the bottom end of the fixed rod 47, and the upper surface of the extrusion block 48 is in contact with the outer wall of the fixed column 46. By rotating the simulated track 31 upward around the fixed axis 33, the fixed column 46 is driven to rotate together, and the fixed column 46 pushes the extrusion block 48 and the fixed rod 47 upward, thereby pushing the storage bin 36 upward and adjusting the height of the storage bin 36 so that the storage bin 36 is aligned with the simulated track 31; the sliding groove 49 is opened on one side of the support frame 35. 49 is used to install sliding block 410; sliding block 410 is fixedly connected to one side of the outer wall of storage bin 36, and sliding block 410 and sliding groove 49 are slidably interlocked. Sliding block 410 moves together with storage bin 36; positioning rod 411 is fixedly connected to the upper surface of test platform 1, and positioning rod 411 and sliding block 410 are slidably interlocked. Positioning rod 411 is used to install sliding block 410. As storage bin 36 moves, it drives sliding block 410 to move vertically along positioning rod 411 to ensure stable movement of storage bin 36; positioning hole 412 is opened on one side of the outer wall of positioning rod 411. Positioning holes 412 are vertically and equidistantly spaced. Positioning holes 412 are used to limit and fix storage bin 36.The positioning bolt 413 is threaded onto one side of the sliding block 410. One end of the positioning bolt 413 is slidably inserted into the positioning hole 412. The positioning bolt 413 moves together with the storage bin 36 and the sliding block 410. By rotating and tightening the positioning bolt 413, one end of it is inserted into one of the positioning holes 412, thus fixing the storage bin 36 and facilitating the adjustment of the height of the storage bin 36.

[0054] A through hole 5 is provided on one side of the upper surface of the test platform 1. The through hole 5 is aligned with the bottom end of the simulated track 31. The simulated mud and debris flow material in the simulated track 31 enters the through hole 5 and then enters the collection box 6. The collection box 6 is fixedly connected to the test platform 1. The top of the collection box 6 corresponds to the position of the through hole 5. The simulated mud and debris are collected and stored through the collection box 6.
