Description

Technical Field

[0001] This invention relates to the field of physical demonstration devices, and in particular to a demonstration device for converting cyclic buoyancy into mechanical power. Background Technology

[0002] In the field of mechanics demonstration devices, the verification and visualization of the principle of buoyancy has always been a core component of physics teaching and engineering experiments. However, current technology lacks demonstration devices capable of cyclically converting buoyancy into power.

[0003] Traditional buoyancy demonstration devices mostly employ static verification methods, such as verifying Archimedes' principle through a simple combination of a metal block and a water tank, or observing changes in buoyancy by altering variables such as liquid density and object shape. These devices have significant drawbacks: the experiments rely heavily on manual operation, such as slowly adding water and adjusting counterweights, leading to low efficiency and difficulty in reproducibility; the phenomena are not intuitive enough, making it difficult for students to develop a deeper understanding of the causes of buoyancy and its relationship with displaced liquid through a single experiment; and there is a lack of interactivity, with students largely in a passive learning state, lacking opportunities for active exploration and critical thinking. Furthermore, while some advanced teaching aids incorporate digital tools such as pressure sensors and high-speed cameras to achieve dynamic visualization of buoyancy changes, they are still limited to single or limited demonstrations and cannot realize the cyclical conversion of buoyancy and its power output. Summary of the Invention

[0004] The purpose of this invention is to provide a demonstration device for converting cyclic buoyancy into mechanical power, thereby solving the aforementioned problems in the prior art.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A demonstration device for converting buoyancy into mechanical power includes a vertically arranged water tank and a horizontally arranged release mechanism; a motion channel is provided through the middle of the water tank, and the release mechanism moves horizontally within the motion channel; The release mechanism includes a housing with a first baffle in the middle, dividing the housing into a release chamber and a water inlet chamber. A movable groove is provided inside the release chamber, and a U-shaped push plate is horizontally movable within the groove. An elastic element is installed in the groove of the U-shaped push plate. A buoyancy block is provided between the movable groove and the back of the U-shaped push plate. At least two pistons are horizontally installed on the side wall of the movable groove. The fixed end of the piston is fixedly connected to the inner wall of the release chamber, and the movable end of the piston is fixedly connected to the side wall of the U-shaped push plate. A water inlet is provided at the bottom of the first baffle, communicating with the fixed end of the piston. Inlet and outlet holes are provided at the bottom of the movable groove, and an inlet hole is provided on the top wall of the water inlet chamber. Rollers are provided on the inner side wall of the water tank.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, a second baffle is provided inside the release chamber. The second baffle seals and divides the inner cavity of the release mechanism into a movable groove and a water inlet channel. The water inlet channel is connected to the water inlet, and the fixed end of the piston passes through the second baffle and is connected to the water inlet channel.

[0008] Furthermore, the roller is a self-driven power generation roller, and the roller is electrically connected to the battery through a charging and discharging module.

[0009] Furthermore, support plates are installed on both sides of the water storage tank at the same height as the lower end face of the movable trough.

[0010] Furthermore, both the elastic element and the buoyancy block are made of silicone rubber closed-cell foam.

[0011] Furthermore, a wire mesh is installed at the top of the movable groove above the U-shaped push plate.

[0012] Furthermore, the top wall of the water inlet chamber is provided with vents that can be closed or opened.

[0013] The beneficial effects of this invention are as follows: This device, through its ingenious structural design, concretizes the abstract process of buoyancy doing work. After the buoyancy block is released into the water, it floats along the height of the water tank due to its own buoyancy, directly driving the rollers on the side wall of the water tank to rotate. This process clearly demonstrates to the observer the complete path of "buoyancy" being converted into "mechanical power." Combined with the lateral reciprocating motion of the release mechanism, new buoyancy blocks can be continuously added, achieving uninterrupted cyclical demonstration. Attached Figure Description

[0016] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0017] Example 1 like Figures 1 to 4 As shown, a cyclic buoyancy conversion mechanical power demonstration device includes a vertically arranged water tank 1 and a horizontally arranged release mechanism 2; a motion channel 11 is provided through the middle of the water tank 1, and the release mechanism 2 moves horizontally within the motion channel 11. The release mechanism 2 includes a housing 21. A first baffle 22 is provided in the middle of the housing 21, dividing the housing 21 into a release chamber 211 and a water inlet chamber 212. A movable groove 2111 is provided in the release chamber 211, and a U-shaped push plate 2113 is horizontally movable in the movable groove 2111. An elastic element 2114 is provided in the groove of the U-shaped push plate 2113. A buoyancy block 2115 is provided between the movable groove 2111 and the back of the U-shaped push plate 2113. At least two pistons 2116 are horizontally arranged on the wall. The fixed end of the piston 2116 is fixedly connected to the inner wall of the release chamber 211, and the movable end of the piston 2116 is fixedly connected to the side wall of the U-shaped push plate 2113. The bottom of the first baffle 22 is provided with a water inlet 221, which is connected to the fixed end of the piston 2116. The bottom of the movable groove 2111 is provided with a water inlet and outlet hole 2112, and the top wall of the water inlet chamber 212 is provided with a water inlet hole 2121. Rollers 12 are provided on the inner side wall of the water storage tank 1.

[0018] In the initial state, the release chamber 211 and the water inlet 2121 are located outside the water tank 1. Under the action of the elastic element 2114, the buoyancy block 2115 is squeezed and limited. When the release chamber 211 moves into the water tank 1, the water inlet 2121 is located inside the water tank 1. Water enters the release chamber 211 through the water inlet 2121, the water inlet 221 and the water inlet and outlet 2112, and enters the fixed end of the piston 2116. Under the action of water pressure, the movable end of the piston 2116 is pushed to extend, which drives the U-shaped push plate 2113 to squeeze and limit the elastic element 2114. At the same time, the U-shaped push plate 2113 moves away from the buoyancy block 2115, so that the buoyancy block 2115 is released. Under the action of buoyancy, the buoyancy block 2115 floats up along the height direction of the water tank 1 and pushes the roller 12 to rotate, thereby realizing the demonstration of converting buoyancy into power. When the release chamber 211 is reset, the buoyancy block 2115 is put in again. The water in the release chamber 211 is discharged through the inlet and outlet holes 2112. The water pressure disappears, the elastic element 2114 and the piston 2116 are reset, and the buoyancy block 2115 is squeezed and fixed again to restore the initial state. This cycle is repeated to demonstrate the conversion of buoyancy into power.

[0019] This device, through its ingenious structural design, visualizes the abstract process of buoyancy doing work. After being released into the water, the buoyancy block 2115 floats along the height of the water tank 1 using its own buoyancy, directly driving the roller 12 on the side wall of the water tank 1 to rotate. This process clearly demonstrates to the observer the complete path of "buoyancy" being converted into "mechanical power." Combined with the lateral reciprocating motion of the release mechanism 2, new buoyancy blocks 2115 can be continuously added, achieving uninterrupted cyclical demonstration.

[0020] In practice, sealing rings 13 are provided at both openings of the motion channel 11. The sealing rings 13 fit against the side wall of the release mechanism 2 to achieve the purpose of sealing and preventing water leakage. In addition, the water tank 10 and the tank body 21 can be made of transparent material to facilitate observation during the demonstration.

[0021] Example 2 This embodiment is a further improvement on embodiment 1, as detailed below: A second baffle 2117 is provided inside the release chamber 211. The second baffle 2117 seals and divides the inner cavity of the release mechanism 2 into a movable groove 2111 and a water inlet channel 2118. The water inlet channel 2118 is connected to the water inlet 221. The fixed end of the piston 2116 passes through the second baffle 2117 and is connected to the water inlet channel 2118. This allows the water pressure to act more effectively on the piston 2116.

[0022] Example 3 This embodiment is a further improvement on embodiment 1, as detailed below: The roller 12 is a self-driven power generation roller, which is electrically connected to the battery through a charging and discharging module. It can store the mechanical power converted from buoyancy. In specific implementation, a driving device is also provided. The driving device is electrically connected to the battery, and the movable end of the driving device is fixedly connected to the release mechanism 2 to drive the release mechanism 2 to reciprocate. In addition, the roller 12 is preferably fixed to both sides of the water tank 1 in a V-shape with the bracket facing upward to play a guiding role and facilitate the floating of the buoyancy block 2115. Multiple sets of rollers 12 are arranged in both the horizontal and vertical directions to cover the movement path of the buoyancy block 2115.

[0023] Support plates 14 are respectively installed on both sides of the water storage tank 1 at the same height as the lower end face of the movable trough 2111. In specific implementation, the bottom of the support plate 14 is provided with triangular brackets that are fixedly connected to the side wall of the water storage tank 1 to support the support plate 14.

[0024] Both the elastic element 2114 and the buoyancy block 2115 are silicone rubber closed-cell foam. Silicone rubber closed-cell foam has a high compression resilience and low water absorption rate; in specific implementations, drainage holes are also provided on the side wall of the release chamber 211.

[0025] A wire mesh 2119 is provided at the top of the movable groove 2111 above the U-shaped push plate 2113. This prevents the elastic element 2114 from detaching from the U-shaped push plate 2113.

[0026] The top wall of the water inlet chamber 212 is provided with a vent 2122 that can be closed or opened. In specific implementation, a solenoid valve is installed at the vent 2122. When the release chamber 211 is located inside the water tank, the vent 2122 is located outside the water storage tank 1, the solenoid valve is open, and it is connected to the outside atmosphere, which is conducive to water in the water storage tank 1 entering the water inlet chamber 212. When the release chamber 211 is moved out of the water storage tank 1, the vent 2122 is located inside the water storage tank 1, the solenoid valve is closed, and the vent 2122 is closed, which can prevent water in the water storage tank 1 from entering the water inlet chamber 212.

[0027] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
