Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of buoyancy and sinking test devices, and more specifically, it relates to a density-adjustable buoyancy and sinking test device. Background Technology
[0002] In the existing technology, most buoyancy and sinking experimental devices usually rely on adding different concentrations of dissolved substances to adjust the density of the liquid. However, this method lacks flexibility. During the adjustment process, factors such as the amount of dissolved substance, the dissolution rate, and the stirring of the solution need to be repeatedly controlled. After each adjustment, the experimenter needs to manually measure the density to confirm the effect of the adjustment. The change in density is often not immediately noticeable and may take some time to stabilize completely.
[0003] In some experimental designs, researchers may wish to fix the state of a liquid at a certain density for long-term observation or testing. However, existing devices often cannot easily release the density-fixed state; once the liquid density reaches the desired level, it is usually necessary to maintain this state by adding other dissolving substances or changing the solution temperature.
[0004] Even after adjusting to the ideal density through cumbersome operations, existing buoyancy and sinking experimental devices usually cannot effectively maintain this density state after the liquid density reaches a certain fixed value. The density of the liquid may change slightly due to various circumstances, causing the liquid density to become unstable, which in turn affects the repeatability and reliability of the experimental results.

The adjustment assembly includes a fixed frame 2, a mounting tube 3, a moving rod 4, a top plate 5, and a fixed tube 6. The fixed frame 2 is mounted on the cylindrical body 1, the mounting tube 3 is mounted on the fixed frame 2, the moving rod 4 is slidably connected to the fixed frame 2, the top plate 5 is mounted on the cylindrical body 1, and the fixed tube 6 is mounted on the top plate 5. The fixed tube 6 and the moving rod 4 are slidably connected. A control assembly is provided on the mounting tube 3. The control assembly includes a rotating ring 7, an adjusting block 8, and a mounting plate 9. The rotating ring 7 is rotatably connected to the mounting tube 3, the adjusting block 8 is connected to the rotating ring 7, and the mounting plate 9 is mounted on the fixed tube 6.
[0033] A fixing plate 10 and an airbag 11 are evenly installed on the fixing tube 6. One end of the airbag 11 is in close contact with the fixing plate 10. A moving groove 12 is provided on the fixing tube 6.
[0034] Pressure plates 13 are evenly installed on the moving rod 4, and the pressure plates 13 are in close contact with the other end of the airbag 11.
[0035] The fixed tube 6 has evenly spaced air intake holes 14.
[0036] A sliding block 15 is provided on the movable rod 4.
[0037] A first spring 16 is provided between the movable block 15 and the mounting plate 9. A through groove 17 is provided on the movable block 15, which is adapted to the rotating block 19.
[0038] In this embodiment, during use, water is injected into the cylinder 1. When it is necessary to adjust the water density in the cylinder 1, the moving rod 4 slides along the fixed frame 2. During this sliding movement, it slides along the top plate 5 on the cylinder 1, and during this sliding movement, it moves the pressure plate 13 along the fixed pipe 6. During this sliding movement, it compresses the air bladder 11 between the fixed plate 10 and the pressure plate 13 in the fixed pipe 6. During this compression, it compresses the cylinder... Water in body 1 is drawn into fixed pipe 6 through suction hole 14, thus facilitating the adjustment of liquid density in body 1. Before use, rotating ring 7 on mounting pipe 3 is rotated, causing adjusting block 8 to rotate along moving rod 4. When rotating to pass through groove 17, the restriction of first spring 16 between mounting plate 9 and moving block 15 is released, allowing moving block 15 to slide along moving rod 4 under the action of elastic potential energy of first spring 16.
[0039] Please see Figure 5-7 As an embodiment of a density-adjustable buoyancy and sinking experimental device for a fixed component: a fixed component is provided on the moving rod 4. The fixed component includes a rotating bar 18, a rotating block 19, and a second spring 20. The rotating bar 18 and the rotating block 19 are rotatably connected to the moving rod 4. One end of the rotating block 19 is slidably connected to the rotating block 19. The second spring 20 is connected between one end of the rotating block 19 and the rotating bar 18.
[0040] The movable rod 4 has a storage groove 21, which is adapted to the rotating bar 18.
[0041] More specifically, during the sliding movement of the movable block 15 along the movable rod 4, one end of the movable block 15 comes into contact with the rotating bar 18, thereby squeezing it. During this squeezing process, one end of the rotating block 19 slides along the rotating bar 18, and the rotating block 19 rotates along the movable rod 4. When one end of the rotating block 19 moves along one end of the rotating bar 18, the second spring 20 between the rotating block 19 and the rotating bar 18 is compressed, thereby completing the placement process of the rotating bar 18 into the storage groove 21. This allows the movable rod 4 to move along the movable groove 12 in the mounting pipe 3, thus completing the process of adjusting the water density in the cylinder 1.
[0042] In summary, during the use or operation of the overall equipment: During use, water is injected into the cylinder 1. When it is necessary to adjust the water density in the cylinder 1, the moving rod 4 slides along the fixed frame 2. During this sliding movement, it slides along the top plate 5 on the cylinder 1, and during this sliding movement, it moves the pressure plate 13 along the fixed pipe 6. During this sliding movement, it compresses the air bladder 11 between the fixed plate 10 and the pressure plate 13 in the fixed pipe 6. During this compression process… This allows the water source in the cylinder 1 to be drawn into the fixed pipe 6 through the suction hole 14, thus facilitating the adjustment of the liquid density in the cylinder 1. Before use, the rotating ring 7 on the mounting pipe 3 is rotated, causing the adjusting block 8 on it to rotate along the moving rod 4. When the ring rotates to pass through the groove 17, the restriction of the first spring 16 between the mounting plate 9 and the moving block 15 is released, allowing the moving block 15 to slide along the moving rod 4 under the action of the elastic potential energy of the first spring 16.
[0043] During the sliding movement of the movable block 15 along the movable rod 4, one end of the movable block 15 comes into contact with the rotating bar 18, thereby squeezing it. During the squeezing process, one end of the rotating block 19 slides along the rotating bar 18, and the rotating block 19 rotates along the movable rod 4. When one end of the rotating block 19 moves along one end of the rotating bar 18, the second spring 20 between the rotating block 19 and the rotating bar 18 is compressed, thereby completing the placement process of the rotating bar 18 into the storage groove 21. This allows the movable rod 4 to move along the movable groove 12 in the mounting pipe 3, thereby completing the process of adjusting the water density in the cylinder 1.
