Description

Technical Field

[0001] This invention relates to the field of river simulation devices, specifically to a flume structure for simulating sedimentation sequences under different hydrodynamic conditions. Background Technology

[0002] River channel simulation is the process of simulating and predicting river flow, sediment transport, and other processes based on the hydrological and topographical conditions of actual rivers using mathematical models and computer technology. Depending on the simulation dimension, river channel simulation can be divided into one-dimensional, two-dimensional, and three-dimensional simulations. One-dimensional simulation mainly focuses on the average hydraulic elements of the river cross-section and long-term riverbed deformation, suitable for predicting scour and deposition trends over long river sections and time periods. Two-dimensional simulation can analyze the horizontal velocity distribution and detailed changes in the riverbed, enabling a more precise simulation of complex river flow conditions. Three-dimensional simulation further achieves a complete simulation of river water and sediment transport, more realistically reflecting the actual conditions of the river. Furthermore, the core technologies of river channel simulation include numerical discretization, sediment-carrying capacity calculation, and bedload transport rate calculation. Numerical discretization technology discretizes continuous mathematical equations into algebraic equations for computer solution. Sediment-carrying capacity calculation determines the amount of sediment that the river flow can carry, which is an important parameter for simulating riverbed deformation. Bedload transport rate calculation describes the speed and quantity of sediment movement in the riverbed under the action of water flow. In the simulation process, numerical methods such as the finite difference method and the finite volume method are usually used to solve nonlinear differential equations. These methods can handle complex boundary conditions and flow situations, improving the accuracy and reliability of the simulation.

[0003] The following problems exist: During the river channel simulation experiment, the staff faced a major challenge: the inability to accurately control the water-sand mixing ratio. This problem prevented them from accurately recording relevant experimental data, and the lack of precise data recording severely affected the authenticity of the experimental results. In addition, the planar and vertical deposition of water and sand could not be clearly displayed during the river channel simulation experiment, which further exacerbated the difficulty in controlling the water-sand mixing ratio. Because the depositional sequence of water and sand could not be clearly observed, the staff lacked effective reference when adjusting the mixing ratio, thus failing to effectively control the water-sand mixing ratio. This series of problems not only affected the accuracy of the experiment but also limited the reliability and application value of the experimental results. Summary of the Invention

Detailed Implementation

[0017] To provide a detailed explanation of the present invention, a thorough description will be given below with reference to the accompanying drawings. It is obvious that the described embodiments are merely some embodiments of the present invention, and not all embodiments of the present invention. It should be understood that the present invention is not limited to the exemplary embodiments described herein.

[0018] The following description, with reference to the accompanying drawings, illustrates a water tank structure for simulating sedimentation sequences under different hydrodynamic conditions, according to an embodiment of the present invention.

[0019] Reference Figure 1-3 This application provides one embodiment: a water tank structure for simulating sedimentation sequences under different hydrodynamic conditions, including a platform 1, a water tank 2 with a length of 100cm and a width of 10cm, and a total height of 140cm. The water tank 2 allows for the simulation of planar sedimentation sequences. A mixing tank 3 is located at one end of the top of the platform 1, allowing for thorough mixing of water and sand. A vertically penetrating placement cavity 4 is located at the other end of the top of the platform 1. The internal spaces of the water tank 2, the mixing tank 3, and the placement cavity 4 are interconnected. Both ends of the bottom are fixedly connected to upright plates 5, which are located on both sides below the placement cavity 4. U-shaped sliding frames 6 are fixedly connected to the bottom of each upright plate 5. Baffles 7 are fitted onto the inner walls of the U-shaped sliding frames 6. A transparent stacking box 8 is fitted onto the inner wall of the placement cavity 4. The top of the transparent stacking box 8 has an opening. By setting up the transparent stacking box 8, vertical deposition sequences can be simulated. The transparent stacking box 8 is made of transparent acrylic plastic sheet, making it convenient for staff to view the vertical deposition results. The baffles 7 can be used to fix the transparent stacking box 8. When the baffles 7 are pulled out from the two sets of U-shaped sliding frames 6, the transparent stacking box 8 can be disassembled, replaced, and cleaned.

[0020] Specifically, a pad 9 is fixedly connected to one outer wall of the platform 1, a column 10 is fixedly connected to the top of the pad 9, a slide rail 11 is fixedly connected to the top of the column 10, a slide table 12 is slidably connected to both ends of the inner wall of the slide rail 11, a gimbal 13 is fixedly connected to the bottom center of the slide table 12, and a camera 14 is fixedly connected to the movable end of the bottom of the gimbal 13. The movable end of the gimbal 13 can rotate back and forth. When the slide table 12 slides on the slide rail 11, the shooting position of the camera 14 can be adjusted. By setting the gimbal 13, the shooting angle of the camera 14 can be adjusted. By setting the camera 14, the stacking process and stacking results can be recorded, and the stacking situation can be quickly viewed. Both ends of the outer wall of the slide frame 11 are slidably connected to sliders 15. The bottom of each slider 15 is fixedly connected to a vertical rod 16. The bottom of each vertical rod 16 is fixedly connected to a horizontal plate 17. When the slider 15 slides back and forth on the slide frame 11, the horizontal plate 17 can slide under the camera 14 without contacting the camera 14.

[0021] Specifically, a through-hole is formed in the horizontal plate 17, and a cylinder 18 is installed on the inner wall of the hole. The movable end of the cylinder 18 is vertically downward, and a first mounting plate 19 is fixedly connected to the movable end of the cylinder 18. A second mounting plate 20 is installed at the bottom of the first mounting plate 19. Threaded rods 21 are fixedly connected to both ends of the top of the second mounting plate 20. The outer walls of the threaded rods 21 are vertically upward, penetrating both ends of the first mounting plate 19 and extending outward. Nuts 22 are threadedly connected to the extended ends of the threaded rods 21. A cleaning brush 23 is fixedly connected to the bottom of the second mounting plate 20. By setting the connection structure between the threaded rods 21 and the nuts 22, the second mounting plate 20 can be fixed to the first mounting plate 19. By setting up a simple connection between the first mounting plate 19, the threaded rod 21, and the nut 22, the disassembly and assembly of the cleaning brush 23 becomes more convenient and quick. After the cylinder 18 is turned on, the cylinder 18 will extend downwards, and the cleaning brush 23 will be inserted into the water tank 2. At this time, the bottom surface and the two outer walls of the cleaning brush 23 are in close contact with the three sides of the inner wall of the water tank 2. Then, the horizontal plate 17 is pushed, and the cleaning brush 23 can slide back and forth in the water tank 2 to remove the sediment in the water tank 2. The removed sediment will fall into the transparent accumulation box 8. When the sediment in the water tank 2 is cleaned, the transparent accumulation box 8 can be disassembled, and then the sediment in the transparent accumulation box 8 is uniformly processed.

[0022] Specifically, the front and rear ends of the platform 1 are fixedly connected to shafts 24. Side plates 25 are rotatably connected to the outer walls of the shafts 24. A base 26 is fixedly connected to the bottom of the side plates 25. A support block 27 is fixedly connected to one end of the top of the base 26. A jack 28 is fixedly connected to the top of the support block 27. A rotating assembly 29 is fixedly connected to the top of the jack 28. A load-bearing plate 30 is rotatably connected to the top of the rotating assembly 29. The top surface of the load-bearing plate 30 can slide tightly against the bottom surface of the platform 1. When the jack 28 is lifted upwards, the position of the mixing tank 3 on the platform 1 will tilt upwards, and the mixture in the mixing tank 3 will then flow into the water tank 2. A water tank 31 is fixedly connected to the other outer wall of the platform 1. A glass plate 32 with a water level indicator penetrates the front end of the water tank 31. A water pump 33 penetrates the center of the top of the water tank 31, and a connector is inserted into the outlet of the water pump 33. A delivery pipe 34 is provided. By setting up a water pump 33 and a delivery pipe 34, water in the water tank 31 can be delivered to the mixing tank 3. The operator can control the amount of water delivered to the mixing tank 3 by observing the water level mark on the glass plate 32. A water inlet is opened at one end of the top of the water tank 31, and a sealing plug 35 is fitted on the inner wall of the water inlet. A gravel box 36 is installed at one end of the top of the platform 1 and above the mixing tank 3. A sliding frame 37 runs through the bottom of one side of the outer wall of the gravel box 36. An intercepting plate 38 with a weight sensor is slidably connected to the inner wall of the sliding frame 37. When gravel is poured into the gravel box 36 from above, the gravel will accumulate on the intercepting plate 38. The operator can control the amount of gravel delivered to the mixing tank 3 by observing the weight displayed by the weight sensor on the intercepting plate 38. By controlling the amount of water and gravel, the equal proportion of water and sand can be achieved.

[0023] Specifically, by simulating various hydrodynamic conditions as the main thread, the tilt angle of the device can be adjusted to simulate different river types. When the tilt angle is small and the hydrodynamic conditions are relatively weak, the simulated river morphology may resemble a meandering river. As the tilt angle changes, the hydrodynamic conditions also change accordingly, simulating braided rivers, straight rivers, and other river types in sequence. These river types are mainly affected by traction forces and are therefore called traction flows. When the tilt angle increases further, the hydrodynamic conditions become more intense, and the river morphology will transform into gravity flow. Therefore, overall, we use hydrodynamic conditions as the main thread throughout the entire simulation process to simulate various different river types, including traction flows and gravity flows. Ultimately, through these simulation experiments, we can establish a comparison of different river types in a vertical sequence, thereby analyzing and studying the differences between them.
