Description

Technical Field

[0001] This utility model relates to the field of sand table models, and in particular to a waterway simulation circulation system for sand table models. Background Technology

[0002] In fields such as urban planning and water conservancy engineering, sand table model water circulation simulation systems serve as important demonstration and experimental tools. They can intuitively present the movement patterns and circulation processes of water in different geographical environments, providing visual references for project design and teaching demonstrations. This system constructs a miniature water circulation system to simulate natural processes such as rainfall, runoff, and confluence, helping researchers and learners better understand the dynamic changes in water resources. However, during the water circulation process, the technical optimization of impurity treatment has always been a key factor affecting the system's demonstration effect and operational stability.

[0003] Existing water circulation systems in sand table models typically use water pumps as a power source to pump water from a lower level to a higher reservoir or simulated rainfall device. When the pump is turned on, the water flows under pressure along pre-laid pipes or ditches, simulating natural runoff from higher to lower levels. As the water flows through the terrain of the sand table model, different slopes, bends, and simulated buildings are used to depict the water's trajectory in a real environment. When the water reaches the collection area at the bottom of the sand table model, it is pumped out again, and this process is repeated to form a closed water circulation system.

[0004] However, the water flow in the sand table model will continuously absorb dust from the air, debris from the sand table surface, and other impurities during the flow process, which can easily cause the water to become turbid, affecting the demonstration effect of the water circulation system and the accuracy of observing the water flow movement law. It cannot meet the needs of high-quality sand table demonstration and experiment. Therefore, a sand table model water circulation system is proposed to solve the above problems.

[0039] The filtration assembly includes a filter cylinder 11 located on the inner wall of the water tank 2. A fixed bracket 6 is fixedly connected to the top of the sand tray 1. Two rotating shafts 7 are rotatably connected inside the fixed bracket 6. A rotating wheel 9 is fixedly connected to the outer wall of one of the rotating shafts 7. The rotating wheel 9 is used to rotate by the impact force of the water flow, driving the rotating shaft 7 to rotate. Gear 1 8 is fixedly connected to both ends of one of the rotating shafts 7, and gear 2 10 is fixedly connected to both ends of the other rotating shaft 7. Gear 1 8 and gear 2 10 mesh with each other, and gear 1 8 and gear 2 10 work in opposite directions with the rotating shaft 7 to achieve the effect of rotating the filter cylinder 11. The filter cylinder 11 is fixedly connected to the outer wall of the other rotating shaft 7. The filter cylinder 11 is used to filter impurities in the water flow, improving the clarity of the water. A collection component is set on one side of the filter cylinder 11. Multiple blades on the outer wall of the rotating wheel 9 are inclined. The blades are used to enhance the impact force of the water flow on the rotating wheel 9 and improve the rotation efficiency of the rotating wheel 9. The top of the sand tray 1 is fixedly connected to... There are two fixing blocks 25, which are used to fix the collection component and prevent it from shifting during operation. The collection component includes a collection box 16, which is located on one side of the filter cylinder 11. The bottom of the collection box 16 is higher than the bottom of the inner wall of the water tank 2. The collection box 16 is used to collect the impurities filtered out by the filter cylinder 11 and prevent the impurities from re-entering the water tank 2. A scraper 12 is fixedly connected to one side of the top of the collection box 16. One side of the scraper 12 is in contact with the outer wall of the filter cylinder 11. The scraper 12 is used to scrape off the impurities on the surface of the filter cylinder 11 and prevent the impurities from clogging the filter cylinder 11. The outer wall of the scraper 12 has an inclined structure, which is used to guide the scraped impurities into the collection box 16. A filter screen 14 is fixedly connected to the bottom of the inner wall of the collection box 16. The filter screen 14 is used to drain the water in the impurities and reduce the water content of the impurities.

[0040] Reference Figure 4 and Figure 5The disassembly assembly includes multiple retaining balls 23 located on both sides of the collection box 16. The retaining balls 23 are used to fix the position of the collection box 16 and prevent it from loosening during operation. Connecting plates 13 are fixedly connected to both sides of the filter screen 14. Each connecting plate 13 is abutted against the top of the fixing block 25.

A connecting cylinder 17 is fixedly connected inside each connecting plate 13. 17 is used to accommodate the ball 23 and the drive column 21, providing space for the disassembly of the components. Each connecting cylinder 17 has multiple holes inside, each hole having an inner wall that is wider at one end and narrower at the other, with the smaller diameter end located on the outward side of the connecting cylinder 17. These holes limit the movement range of the ball 23, preventing accidental detachment. A ball 23 is slidably connected to the inner wall of each hole. The ball 23 engages with the groove inside the fixing block 25 to secure and release the collecting box 16. Each side of the ball 23 engages with the groove inside the fixing block 25, which in turn engages with the ball 23 to secure the collecting box 16. At the location of the header 16, each connecting cylinder 17 has a fixed retaining ring 18 fixedly connected to its inner wall. The retaining ring 18 is used to fix the spring 19 and the transmission column 21, providing a support structure for the disassembly assembly.

Each transmission column 21 has a push block 22 fixedly connected to its bottom end. The push block 22 is used to push the retaining ball 23, causing it to disengage from the groove of the retaining block 25. Each push block 22 has an inclined outer wall, and the inclined surface fits against the ball 23. The inclined surface is used to reduce the friction between the push block 22 and the ball 23 and improve the smoothness of movement. Each transmission column 21 has a spring 19 on its outer wall. The spring 19 is used to provide a restoring force so that the transmission column 21 and the push block 22 can automatically return to their original positions. The top of each spring 19 is fixedly connected to the bottom of the fixing ring 18. The bottom of each spring 19 is fixedly connected to a connecting ring 20. The connecting ring 20 is used to fix the other end of the spring 19 and ensure the stability of the spring 19. The inner wall of each connecting ring 20 is fixedly connected to the outer wall of the transmission column 21.

[0041] Working principle: During the filtration of water flow in sandbox 1, the filter cylinder 11 filters impurities in the water flow. The force of the water flow drives the rotating wheel 9 to rotate, causing the gear 8 at both ends of one of the rotating shafts 7 to rotate counterclockwise. Since gear 8 meshes with gear 10, the counterclockwise rotation of gear 8 drives gear 10 to rotate clockwise. This rotational force is transmitted through the other rotating shaft 7 to drive the filter cylinder 11 to rotate clockwise. The scraper 12 scrapes off the impurities attached to the surface of the filter cylinder 11, and the inclined structure of the scraper 12 guides the impurities into the collection box 16. The filter screen 14 discharges the water from the impurities, thus collecting the impurities and achieving a good filtration effect on the water flow. This solves the problem that the water flow absorbs some impurities and dust during the flow process, which easily causes the water to become turbid, and enhances the clarity of the water flow.

[0042] During the process of emptying impurities, the operator holds the support frames 15 on both sides and presses down on the handle 24. As the handle 24 moves, it drives the push block 22 to separate from the outer wall of the ball 23 via the transmission column 21, providing space for the ball 23 to move. Since the groove inside the connecting cylinder 17 has a larger diameter at the inward end and a smaller diameter at the outward end, which is smaller than the outer wall diameter of the ball 23, it provides space for the ball 23 to move while preventing the ball 23 from accidentally slipping. As the transmission column 21 moves, it also drives the connecting ring 20 to move downward, and stretches the spring 19. Then, it pulls the support frames 15 on both sides upward, causing the connecting cylinder 17 inside the connecting plate 13 to separate from the filter screen 14. The inner wall of the filter screen 14 pushes the ball 23 to move into the connecting cylinder 17 until the connecting cylinder 17 is separated from the filter screen 14, achieving the disassembly effect of the collection box 16. This makes it convenient to pour the impurities on the inner wall of the collection box 16 into the designated location. Compared with traditional equipment, the effect of cleaning impurities in water is greatly improved.
