Description

Technical Field

[0001] The invention belongs to the field of marine engineering, and in particular relates to a qin-like wave-making device and a wave-making method. Background Art

[0002] The ocean is the focus of development for all countries in the world. However, the environment in the ocean is complex and diverse, and environmental factors such as sea wind and waves are inevitable. By simulating the motion characteristics of waves, the adaptability of unmanned ships to different sea conditions can be enhanced, thereby improving the safety of their navigation. In order to maintain the stability and good maneuverability of the ship, the control algorithm of the unmanned ship must be adjusted according to the changes in sea conditions. Using the simulated data of wave motion, these control algorithms can be further optimized to enhance the control accuracy and response speed of the ship. Therefore, simulating wave motion plays an extremely important role in the navigation of unmanned ships.

[0003] In the prior art, most wave-making devices generate waves by driving water bodies to move with mechanical external force. For example, in the Chinese patent publication number: CN118209292A, since the wave-making board is in a fixed position, the waves generated often come from only a few directions. In addition, the prior art often only has a single wave-making board, which cannot generate continuous high-frequency waves and is not conducive to simulating complex sea conditions. Summary of the invention

[0004] The purpose of the present invention is to provide a wave-making device and a wave-making method to solve at least one of the above problems, so as to solve the problem of single wave simulation effect in the prior art, realize a wave device that can simulate multiple scenes, and can simulate complex sea conditions in the ocean.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] One of the technical solutions of the present invention is to provide a qin-style wave-making device, which is arranged in an experimental water pool and comprises a wave-making mechanism, a pressing mechanism and a slider mechanism, wherein the pressing mechanism is connected to the slider mechanism, the wave-making mechanism is arranged inside the water pool, and the pressing mechanism contacts the wave-making mechanism and presses the wave-making mechanism to make waves;

[0007] The wave-making mechanism comprises a wave-making board, a spring and a wave-making board support frame, the contact surface of the wave-making board contacts the pressing mechanism, the upper and lower parts of the connection surface of the wave-making board are respectively connected to the inner wall of the experimental water pool through the spring, the wave-making board is connected to the experimental water pool through the wave-making board support frame, and the wave-making board is rotatably connected to the wave-making board support frame;

[0008] The pressing mechanism comprises a pressing plate and an electric cylinder, the contact surface of the wave-making plate contacts the pressing surface of the pressing plate, the pressing plate is hinged to a push rod of the electric cylinder, and the electric cylinder is connected to a slider mechanism;

[0009] The slider mechanism comprises a slider and a lead screw slide, the slider is mounted on a linear guide rail of the lead screw slide, the electric cylinder is connected to the slider, and the pressing mechanism slides along the lead screw slide with the slider.

[0010] Furthermore, the surface where the wavemaking plate contacts the pressing mechanism is the wavemaking plate contact surface, and the surface where the wavemaking plate connects to the spring is the connection surface of the wavemaking plate; the surface where the pressing plate contacts the wavemaking plate is the pressing surface, and the surface where the pressing plate connects to the electric cylinder is the connection surface.

[0011] Furthermore, when the wave-making board is not pressed, the springs are in a tensioned state. After the pressing mechanism presses the upper part of the wave-making board, the springs on the upper part of the wave-making board are compressed and the springs on the lower part are pulled apart. The springs release the stored energy to the wave-making board, so that the wave-making board moves in a circumferential direction with the wave-making board support frame as the axis and the width direction of the wave-making board as the diameter, thereby pushing the water in the experimental pool to create waves.

[0012] Furthermore, a pulley is arranged on the pressing surface of the pressing plate, and the pressing plate contacts the contact surface of the wave-making board through the pulley and presses to make waves. The pulley can reduce the friction between the pressing plate and the wave-making board, which is beneficial for the slider to move back and forth on the screw slide, thereby driving the pressing plate to press the wave-making board to make waves.

[0013] Furthermore, the electric cylinder includes an electric cylinder I and an electric cylinder II. The electric cylinder I is fixedly connected to the slider, so that when the slider moves back and forth on the screw slide, the electric cylinder I can drive the pressing plate to move back and forth to press the wave-making plate. The electric cylinder II is hinged to the slider, and the push rods of the electric cylinder I and the electric cylinder II are connected to the pressing plate through a ball joint. The push rod lengths of the electric cylinder I and the electric cylinder II and the angle between the electric cylinder II and the slider can be adjusted as needed, thereby adjusting the pressing angle and position between the pressing plate and the wave-making plate, which is conducive to freely adjusting the shape of the created waves according to actual conditions.

[0014] Furthermore, the electric cylinder 1 is fixedly connected to the slider by bolts.

[0015] Furthermore, the wave-making mechanism has multiple wave-making boards, the contact surfaces of the multiple wave-making boards are parallel, and they are arranged on the same wave-making board support frame. The pressing plate can continuously press the multiple wave-making boards to create continuous waves through the movement of the slider. The parallel arrangement of the wave-making boards is conducive to reducing the resistance of the slider movement.

[0016] Furthermore, the upper and lower parts of each wave-making board connection surface are connected to the inner wall of the experimental water pool through springs.

[0017] Furthermore, the device also includes a buckle, which is installed on the wave-making board, and the wave-making board located at one end of the wave-making mechanism is not installed with the buckle, while the other wave-making boards are installed with the buckle. When the buckle is fastened, the wave-making boards are connected in pairs to create continuous waves.

[0018] Furthermore, when the buckle is not connected to the wave-making board, when the pressing plate presses the wave-making boards in sequence driven by the slider, the electric cylinder push rod in the forward direction of the pressing plate is shorter than other electric cylinder push rods, and the pressing plate is in an inclined state. This is beneficial for the pressing plate to continuously press multiple wave-making boards to create continuous waves, and is beneficial for reducing the resistance of the slider movement.

[0019] Furthermore, when the wave-making boards are connected by the snap-fit, multiple wave-making boards can be used simultaneously, the slider is in the middle position of the screw slide, and the push rods of the electric cylinder are extended by the same distance, so that the contact pulley plates are in a parallel state for uniform force.

[0020] Furthermore, the slider is installed on the linear guide rail of the screw slide, the screw slide is installed on two slide brackets, the two slide brackets are symmetrically installed on both sides of the experimental water tank, and the pressing mechanism slides along the screw slide with the slider.

[0021] Furthermore, the elongations of the push rods of the two electric cylinders are different. When the difference in the elongations of the push rods of the two electric cylinders is greater and the elongation of the push rod of electric cylinder I is greater, the higher the wave is.

[0022] Furthermore, the higher the slider speed of the screw slide, the higher the wave frequency generated.

[0023] Furthermore, the central axis of the bottom surface of the lead screw slide is parallel to the bottom surface and the side surface of the experimental water pool at the same time.

[0024] The second technical solution of the present invention is to provide a wave-making method using the above-mentioned piano-type wave-making device, wherein the wave-making device controls the extension distance of the two electric cylinder push rods to make the pressing plate press the wave-making plate, thereby generating waves, and at the same time controls the slider to move back and forth along the screw slide, thereby generating different types of waves.

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] 1. The present invention can press the wave-making board by a pressing plate and move the slider at the same time, so that the pressing plate pushes the wave-making board at different positions, thereby generating waves in different directions. By controlling the elongation length of the electric cylinder push rod, the pressing degree of the spring connected to the wave-making board is controlled, and then the energy released by the spring is controlled to control the size of the generated waves.

[0027] 2. The present invention can press the wave-making board through the pressing plate while moving the slider, and can generate continuous waves of different frequencies by changing the moving speed of the slider. The frequency of the waves can be directly controlled by adjusting the movement frequency of the slider and the pressing plate.

[0028] 3. The present invention can control multiple wave-making boards at the same time through buckles, and continuously press the wave-making boards through the pressing plate to change the waveform of the created waves. The waveform of the wave is related to the size of the wave-making board. The size of the wave-making board will affect the generation and propagation mode of the wave and the final shape and characteristics; the size of the wave-making board, especially the length and width, will affect the wavelength of the wave (i.e., the distance between adjacent wave crests). A larger wave-making board can push more water, thereby producing a longer wavelength, and a smaller wave-making board pushes less water, and the wavelength will also be relatively shorter; the size of the wave-making board also affects the height of the wave. A larger wave-making board can move more water and can usually produce higher waves. The larger the area of ​​the wave-making board, the stronger the force pushing the water and the higher the wave.

[0029] 4. The present invention has a simple structure and can create waves of different sizes, directions and waveforms, and can simulate a variety of complex sea conditions. BRIEF DESCRIPTION OF THE DRAWINGS
