Abstract
Description
Technical Field
[0001] This utility model relates to the field of static water pressure demonstration, specifically a static water pressure distribution diagram demonstration device. Background Technology
[0002] Hydrostatic pressure refers to the pressure exerted at a point within a stationary liquid due to the liquid's own weight. Its magnitude depends only on the liquid's density, the acceleration due to gravity, and the depth of that point within the liquid, and is independent of the orientation of the pressure surface. In a stationary liquid, the pressure increases linearly with depth, and at the same depth, the pressure is equal in all directions.
[0003] In classroom teaching, explaining hydrostatic pressure distribution diagrams often faces a challenge: a lack of intuitive and effective demonstration tools. While traditional theoretical explanations can illustrate the principle that hydrostatic pressure increases with depth, students often struggle to form an intuitive understanding. Due to the lack of dynamic, visual aids to demonstrate the pressure distribution at different depths, students may simply memorize formulas mechanically without truly grasping the physical meaning of hydrostatic pressure.
[0004] An ideal teaching aid should clearly display the pressure changes at different depths within a liquid, such as through differences in column height, transforming the abstract concept of pressure into intuitive visual information. Such an aid not only stimulates students' interest in learning but also helps them better understand the essence of hydrostatic pressure distribution diagrams, thereby improving classroom teaching effectiveness. Therefore, developing or introducing suitable hydrostatic pressure distribution diagram demonstration teaching aids is of great significance for improving teaching quality. Utility Model Content

[0018] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.
[0019] Please see Figures 1 to 3 This utility model provides a technical solution: a static water pressure distribution diagram demonstration device, including a water tank structure 1, a demonstration structure 2 fixedly connected to the outside of the water tank structure 1, the water tank structure 1 including a water tank body 11, the inside of the water tank body 11 is hollow, and a movable plate 12 is threadedly connected to the top of the water tank body 11.
[0020] This demonstration device can transfer water from the tank structure 1 to the demonstration structure 2. By observing the multiple sets of floats 223 of different heights inside the demonstration structure 2, the distribution of hydrostatic pressure at different water levels can be clearly demonstrated. The entire device is simple in structure and easy to operate, making it convenient to intuitively demonstrate what hydrostatic pressure is during classroom demonstrations. By observing the position of the floats 223, it can be directly shown that the pressure increases linearly with increasing depth.
[0021] The movable plate 12 includes a sealing cover 121, a waterproof hydraulic rod 122 is fixedly connected to the bottom end of the sealing cover 121, and the plate body 123 is fixedly connected to the bottom end of the waterproof hydraulic rod 122.
[0022] Demonstration structure 2 includes demonstration board 21, and a single set of demonstration slots 22 are provided on the surface of demonstration board 21. The single set of demonstration slots 22 is provided in several sets and is evenly distributed on the surface of demonstration board 21.
[0023] The single demonstration tank 22 includes a water tank 221, which is formed on the surface of the demonstration board 21. A transparent acrylic plate 222 is fixedly connected to the front end of the water tank 221. A float ball 223 is installed inside the water tank 221. A scale 224 is etched on the surface of the demonstration board 21 corresponding to the water tank 221.
[0024] A conduit 23 is fixedly connected to one side of the demonstration board 21. The conduit 23 has several sets and corresponds one-to-one with a single demonstration slot 22.
[0025] One end of the conduit 23 is connected to the main body of the water tank 11, and the other end of the conduit 23 is connected to the corresponding single demonstration tank 22.
[0026] When in use, the conduit 23 can guide the water inside the water tank body 11 to the corresponding water tank 221. The floats 223 in the water tank 221 are in different positions due to the influence of water pressure. The closer the float is to the lower layer, the greater the water pressure it experiences and the further away it is from the water tank body 11. Conversely, the closer the float is to the upper layer, the less water pressure it experiences and the closer it is to the water tank body 11. This can also be well sensed by observing the scale 224.
[0027] In addition, the height of the main body 123 of the plate can be controlled by the extension and retraction of the waterproof hydraulic rod 122. As the waterproof hydraulic rod 122 retracts upward, the main body 123 of the plate will move upward, causing the water inside to move upward as a whole. At this time, the water level inside the main body 11 of the water tank rises, and the pressure inside the water tank 221 located above increases, which will squeeze the float 223 inside to move away from the main body 123 of the plate, thus more intuitively feeling the distribution principle of hydrostatic pressure at different water levels.
