Description

[0002] In fluid mechanics experiments, a simulated water tank is a specially designed experimental device used to study the impact of water flow on objects. These water tanks can simulate waves, flows and other hydrodynamic phenomena in the actual ocean environment, helping us to directly observe the movement of objects in the water. In addition, the simulated water tank can provide regulated experimental conditions to verify the accuracy of theoretical predictions, and can also be used to evaluate the various performance of ships, including resistance, propulsion, maneuverability and wave resistance. Simulated water tank experiments can obtain necessary information before actual sea trials. With the advancement of computational fluid dynamics (CFD) technology, the application of simulated water tanks is also expanding, becoming an important tool for studying ship hydrodynamics.

[0028] To ensure that the traction direction of the ship model is always horizontal when the ship model is towed back and forth.

[0029] See also Figure 1 、 Figure 2 and Figure 3 As shown, the present application provides an experimental water tank device, including a tank body 1, a guide rail 2, a four-wheeled trolley 3, an electric telescopic rod 4, and a drive motor 5; the tank body 1 is square and filled with water.

[0030] The front and rear sides of the trough body 1 are respectively provided with a guide rail 2 (note: the left and right sides of the trough body 1 are defined by the length direction of the trough body 1, and the front and rear sides of the trough body 1 are defined by the width direction of the trough body 1), and the guide rail 2 is installed on the side edge of the trough body 1.

[0031] The four-wheeled trolley 3 consists of a body and four wheels, symmetrically mounted on both sides of the body. The running wheels on both sides of the four-wheeled trolley 3 are respectively mounted on the two guide rails 2, so that the four-wheeled trolley 3 can move along the length direction of the trough body 1, and the body spans the trough body 1 along the width direction of the trough body 1. The four-wheeled trolley 3 is provided with an electric telescopic rod 4 extending vertically downward, that is, the lower end of the electric telescopic rod 4 extends toward the water surface, and the lower end of the electric telescopic rod 4 is connected to the ship model via a pull rope; thus, by controlling the extension and contraction of the electric telescopic rod 4, the height of the towing point of the ship model can be adjusted so that the height of the towing point of the ship model matches the height of the ship model, effectively ensuring that the towing direction of the ship model is always in a horizontal state, avoiding problems such as the ship model tilting and capsizing.

[0032] The trough body 1 is provided with a drive chain 6 through a sprocket. Specifically, there are two sprockets, namely a drive chain 6 wheel and a driven sprocket. The drive chain 6 wheel and the driven sprocket are respectively located on the sides of the two ends of the guide rail 2, and the drive chain 6 is wound around the drive wheel and the driven wheel. There are two drive chains 6, which are respectively located on the inner sides of the two guide rails 2 and are respectively connected to the four-wheeled trolley 3, so that the drive chain 6 can drive the four-wheeled trolley 3 to move; the drive chain 6 wheels of the two drive chains 6 are fixedly connected by a rotating shaft, so that the two drive chains 6 can rotate synchronously, and the rotating shaft is connected to the output shaft of the drive motor 5; in this way, when the drive motor 5 is working, the two drive chains 6 are driven to rotate at the same time through the rotating shaft, and then move synchronously along the guide rail 2 from both sides of the four-wheeled trolley 3, effectively avoiding the technical problem of deflection of the four-wheeled trolley 3 when moving, and the dragging of the ship model is more stable.

[0033] The four-wheeled trolley 3 is provided with a camera 7 for detecting the height of the ship model. The camera 7 is connected to the signal input end of the controller, and the signal output end of the controller is electrically connected to the electric telescopic rod 4. During the experiment, the camera 7 takes a picture of the ship model, and then uses its own image processing and analysis software to analyze and process the picture to obtain the position height information of the ship model, and transmits the information to the controller. The controller controls the electric telescopic rod 4 to extend or shorten in time according to the input signal, effectively ensuring that the dragging direction of the ship model is always in a horizontal state, thereby avoiding the problem of tilting and overturning when the ship model is dragged.

[0034] A wave-making mechanism 8 for making waves is provided in the tank body 1 .

[0035] In this embodiment, the wave-making mechanism 8 includes a driving assembly 81, a wave-making plate 82, and a driving rod 83; the driving rod 83 is slidably installed at the bottom of the trough body 1, one end of which extends out of the trough body 1 and is connected to the driving assembly 81, and the other end is arranged along the length direction of the trough body 1 and is provided with a wave-making plate 82, and the wave-making plate 82 extends and distributes along the vertical direction. The driving assembly 81 adopts a linear driving assembly 81, a crank 8102, a rocker 8103, etc. In this way, when wave making is required, the driving assembly 81 drives the wave-making plate 82 to move along the length direction of the trough body 1 through the driving rod 83, pushing the water in the trough body 1 forward, thereby creating waves.

[0036] In this embodiment, the drive assembly 81 includes a wave-making motor 8101, a crank 8102, and a rocker 8103; one end of the crank 8102 is connected to the output shaft of the wave-making motor 8101, and the other end is hinged to one end of the rocker 8103, and the other end of the rocker 8103 is hinged to the free end of the drive rod 83. The crank 8102 and the rocker 8103 constitute a crank-rocker mechanism. During operation, the wave-making motor 8101 drives the crank 8102 to rotate, and the crank 8102 drives the drive rod 83 to move through the rocker 8103.

[0037] In this embodiment, the middle part of the wave-making plate 82 is hinged to the driving rod 83, the end of the wave-making plate 82 is hinged to one end of the adjusting telescopic rod 84, the other end of the adjusting telescopic rod 84 is hinged to the driving rod 83, and the adjusting telescopic rod 84 adopts an electric telescopic rod 4 or a hydraulic rod. When the adjusting telescopic rod 84 is actuated, the wave-making plate 82 is driven to rotate, thereby adjusting the angle between the wave-making plate 82 and the horizontal plane, that is, adjusting the pitch angle of the wave-making plate 82, so that the distribution of the pushed water in the vertical direction is different, so that various types of waves can be generated in the trough body 1, meeting the needs of different experiments and improving the flexibility and diversity of wave generation.

[0038] Optionally, in some embodiments, such as Figure 3 and Figure 4As shown, the experimental water tank apparatus also includes a wave height meter 9 for detecting the size of waves within the tank body 1. The wave height meter 9 is connected to the signal input of the controller, and the signal output of the controller is electrically connected to the adjustable telescopic rod 84. When in use, the wave height meter 9 is specifically used to measure the height and period of waves, providing detailed wave information. The data enters the controller, which then performs model training. The machine learning model is trained using historical data to predict dynamic changes in water flow and wave characteristics. A feedback mechanism is established to adjust sensor parameters or water tank operations in real time based on the model's prediction results to achieve better experimental results.

[0039] In some specific embodiments, a Doppler tester is also installed in the tank body 1 to measure the speed and direction of water flow and obtain real-time flow information.

[0040] In some specific embodiments, a pressure sensor is further installed in the tank body 1. The pressure sensor is specifically installed at the bottom of the tank to measure water pressure changes to estimate wave height and other dynamic characteristics.

[0041] The embodiments of the present application have been described above. The above description is illustrative and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is selected to best explain the principles of the embodiments, their practical applications, or improvements to the technology in the market, or to enable other persons skilled in the art to understand the embodiments disclosed herein.
