[0047] The present application embodiment discloses a wave-making device. Figure 1 The wave-making device includes a floating island 1, a mounting seat 3, a wave-making mechanism 4 and a driving mechanism 5.

[0048] The floating island 1 is in a square shape and can float on the water, and the tail of the floating island 1 is open for ships to enter. In this embodiment, the floating island 1 is made of a floating material, such as high-density polyethylene, polyvinyl chloride, etc., so that the floating island 1 can float on the water; in other embodiments, the floating island 1 can also be inflatable, and the floating island 1 can float on the water by inflating the inside of the floating island 1. The inner cavity of the floating island 1 is a test cavity 2 that can be supplied with water. When the floating island 1 is placed on the water surface, water automatically enters the test cavity 2.

[0049] The mounting base 3 is mounted on the floating island 1 and is disposed on opposite sides of the floating island 1 in the width direction, so as to serve as a basis for mounting the wave-making mechanism 4 and the driving mechanism 5 on the floating island 1. The wave-making mechanism 4 is used to make waves, and the driving mechanism 5 is used to drive the wave-making mechanism 4 to rotate and swing, so that the wave-making mechanism 4 can make waves of different types and intensities.

[0050] Reference Figure 2 Specifically, for the wave-making mechanism 4, the wave-making mechanism 4 includes a rotating shaft 41 and a fan blade 42. The rotating shaft 41 is in the shape of a circular shaft and its two ends, which are far from each other, extend to the mounting seats 3 on both sides of the floating island 1. The fan blade 42 is in the shape of a square plate and is mounted on the outer wall of the rotating shaft 41. The length extension direction of the fan blade 42 is parallel to the axial direction of the rotating shaft 41, and the width direction of the fan blade 42 is parallel to the radial direction of the rotating shaft 41. There are two fan blades 42 on the rotating shaft 41, and the two fan blades 42 are respectively mounted on opposite sides of the rotating shaft 41. When the rotating shaft 41 rotates, it can drive the fan blade 42 to rotate together.

[0051] Reference Figure 2 and Figure 3 , for the driving mechanism 5, the driving mechanism 5 is arranged at both ends of the rotating shaft 41. Each driving mechanism 5 includes a rotating seat 51, a power source 52, a linkage 53, an active seat 54, a driven seat 55 and a connecting rod 56. The active seat 54 is cylindrical and rotatably connected to the mounting seat 3, and is located at the part of the mounting seat 3 extending upward out of the water surface. The driven seat 55 is cylindrical with an axis coaxial with the active seat 54 and moves on the mounting seat 3. The two ends of the connecting rod 56 that are far away from each other are respectively fixed to the outer wall of the active seat 54 and the outer wall of the driven seat 55, and the length extension direction of the connecting rod 56 is perpendicular to the length extension direction of the active seat 54. The driven seat 55 is located at the lower position of the active seat 54. The mounting seat 3 is provided with a moving cavity 6 for the connecting rod 56 and the driven seat 55 to swing in a circle around the active seat 54. The extension angle of the moving cavity 6 in the figure is an example. In actual production, the extension angle of the moving cavity 6 can be adjusted according to demand.

[0052] Reference Figure 3 and Figure 4 The rotating seat 51 is coaxially connected to the active seat 54, the end of the rotating shaft 41 is coaxially connected to the driven seat 55, and the rotating seat 51 and the rotating shaft 41 are linked by a linkage 53, so that the rotating shaft 41 rotates synchronously when the rotating seat 51 rotates. A first locking member 7 is provided between the active seat 54 and the mounting seat 3 to lock the two, and a second locking member 8 is provided between the active seat 54 and the rotating seat 51 to lock the two. The power source 52 is connected to an unlocking member 9 that can alternately unlock the first locking member 7 and the second locking member 8.

[0053] When the unlocking member 9 unlocks the first locking member 7, the rotating seat 51 is locked on the active seat 54, and the power source 52 can drive the active seat 54 to rotate back and forth relative to the mounting seat 3, so as to drive the driven seat 55 to swing in a circle around the axis of the active seat 54 through the connecting rod 56, thereby driving the fan blades 42 to push the water flow in the test chamber 2 back and forth to generate waves with a frequency in the test chamber 2.

[0054] When the unlocking member 9 unlocks the second locking member 8, the active seat 54 is locked on the mounting seat 3. At this time, the power source 52 can drive the rotating seat 51 to rotate coaxially relative to the active seat 54, so as to drive the rotating shaft 41 to rotate through the linkage member 53, so that the fan blades 42 cyclically beat and disturb the water flow in the test chamber 2 to generate continuous waves in the test chamber 2.

[0055] Reference Figure 2 and Figure 3 , wherein the linkage member 53 includes a first sprocket 531, a second sprocket 532 and a chain 533. The first sprocket 531, the second sprocket 532 and the chain 533 are all made of waterproof and anti-corrosion materials. The first sprocket 531 is coaxially sleeved and fixed on the outer wall of the rotating seat 51, the second sprocket 532 is coaxially sleeved and fixed on the outer wall of the rotating shaft 41, and the chain 533 is sleeved and meshed on the first sprocket 531 and the second sprocket 532 at the same time. Therefore, when the rotating seat 51 rotates, the transmission of the chain 533 can drive the second sprocket 532 to rotate together with the rotating shaft 41, and a swinging cavity 18 is provided in the mounting seat 3 for the chain 533 and the rotating shaft 41 to swing in a circle around the active seat 54, and the swinging cavity 18 is connected to the moving cavity 6.

[0056] Reference Figure 4 and Figure 5The active seat 54 is coaxially provided with a through hole 11 penetrating opposite ends of the active seat 54, so that the active seat 54 is in the shape of a cylinder with a hollow interior and two ends connected, and the axial direction of the active seat 54 is parallel to the axial direction of the rotating shaft 41. The rotating seat 51 is coaxially provided with a through groove 14 penetrating one end of the rotating seat 51, so that the rotating seat 51 is in the shape of a cylinder with a hollow interior and one end connected, the inner diameter of the rotating seat 51 is consistent with the inner diameter of the active seat 54, the outer diameter of the rotating seat 51 is smaller than the outer diameter of the active seat 54, and the rotating seat 51 is coaxially inserted into the active seat 54 from one end of the active seat 54 and coaxially rotatably connected to the active seat 54 through a bearing (not shown in the figure).

[0057] Reference Figure 2 and Figure 4 The mounting seat 3 is connected with a connecting frame 19, and a telescopic member 10 is fixed on the connecting frame 19. The telescopic member 10 can be a cylinder or an electric telescopic rod, and in this embodiment, it is preferably an electric telescopic rod. The seat body of the telescopic member 10 is fixed on the connecting frame 19, and the telescopic end of the telescopic member 10 is connected to a power source 52. The power source 52 is a rotating motor whose output end can be forward and reversed, and the power source 52 is located at one end of the active seat 54 away from the rotating seat 51. At the same time, the telescopic direction of the telescopic end of the telescopic member 10 and the axial direction of the output end of the power source 52 are coaxial with the axis of the active seat 54.

[0058] Reference Figure 4 and Figure 5 The unlocking member 9 includes a first shaft 91 and a second shaft 92 which are coaxially fixedly connected. The outer diameter of the first shaft 91 is smaller than the inner diameter of the active seat 54, and the outer diameter of the second shaft 92 is consistent with the inner diameter of the active seat 54. When the telescopic member 10 drives the power source 52 to move, the second shaft 92 is always plugged into one of the active seat 54 and the rotating seat 51.

[0059] More specifically, a plurality of limiting teeth 93 with a trapezoidal cross section are fixed uniformly at intervals along the circumference of the second shaft 92. A plurality of first limiting grooves 12 are uniformly spaced on the inner wall of the active seat 54 along the circumference of the active seat 54, and a plurality of second limiting grooves 16 are uniformly spaced on the inner wall of the rotating seat 51 along the circumference of the rotating seat 51. The shapes of the first limiting grooves 12 and the second limiting grooves 16 are both adapted to the limiting teeth 93 for insertion of the limiting teeth 93, and the first limiting grooves 12 correspond to the limiting teeth 93 one by one, and the second limiting grooves 16 also correspond to the limiting teeth 93 one by one.

[0060] When the telescopic end of the telescopic member 10 is in the retracted state, the second shaft 92 is completely located in the active seat 54, and each of the limiting teeth 93 is respectively inserted into each of the first limiting grooves 12. When the telescopic end of the telescopic member 10 is in the extended state, the second shaft 92 is completely located in the rotating seat 51, and the first shaft 91 is located in the active seat 54, and each of the limiting teeth 93 is respectively inserted into each of the second limiting grooves 16.

[0061] Reference Figure 4 and Figure 6 The first locking member 7 includes a locking piece 71 and a first spring 72. The locking piece 71 is in a sheet shape and is opposite to the active seat 54. Specifically, the end of the locking piece 71 away from the active seat 54 is in a square shape, and the end of the locking piece 71 close to the active seat 54 is in a triangular shape with the tip facing the active seat 54. The locking piece 71 slides in the mounting seat 3 along the radial direction of the active seat 54. The outer peripheral wall of the active seat 54 is evenly spaced along its own circumference and is provided with a plurality of slots 13 for the locking piece 71 to be inserted in the direction close to the active seat 54. The slots 13 correspond to the first limiting slots 12 one by one, and the slots 13 are connected to the corresponding first limiting slots 12.

[0062] Reference Figure 2 and Figure 6 The first spring 72 is installed in the mounting seat 3, and the mounting seat 3 has a cavity for making way for the first spring 72. Figure 4 One end of the first spring 72 is connected to the inner wall of the mounting seat 3, and the other end of the first spring 72 is connected to the end of the locking piece 71 away from the active seat 54, and the axis of the first spring 72 is parallel to the moving direction of the connected locking piece 71. The elastic force of the first spring 72 gives the locking piece 71 an elastic force to move toward the active seat 54, so that when the locking piece 71 is opposite to one of the slots 13 on the active seat 54, the end of the locking piece 71 close to the active seat 54 can be pushed by the first spring 72 to be inserted into the slot 13, thereby making the mounting seat 3 and the active seat 54 relatively locked.

[0063] It should be noted that magnets (not shown in the figure) are embedded in the locking piece 71 and the limiting teeth 93. When the telescopic member 10 is recovered and drives the second shaft 92 to be located in the active seat 54, the limiting teeth 93 are opposite to the locking piece 71, and the magnet on the locking piece 71 and the magnet on the limiting teeth 93 have the same magnetic poles opposite to each other, so that the locking piece 71 is subjected to the repulsive magnetic force and squeezes the spring away from the active seat 54 and leaves the slot 13, thereby releasing the lock between the mounting seat 3 and the active seat 54. At this time, the output end of the power source 52 rotates to drive the second shaft 92 to rotate with the active seat 54. When the telescopic member 10 extends to drive the second shaft 92 to leave the active seat 54 and insert into the rotating seat 51, the second shaft 92 gradually leaves the position opposite to the locking piece 71, so that the locking piece 71 can be pushed by the first spring 72 to be reinserted into the active seat 54. What's more, each time the power source 52 drives the active section to stop rotating, each first limit groove 12 is connected to each second limit groove 16 in a one-to-one correspondence, and the locking piece 71 is opposite to one of the slots 13 on the active seat 54, and the locking piece 71 is inserted into different slots 13 to adjust the height and position of the rotating shaft 41 relative to the water surface.

[0064] Reference Figure 5 and Figure 7 The second locking member 8 includes a locking rod 81, a pushing seat 82 and a second spring 83. The pushing seat 82 includes an annular pushing ring 821 and a rod-shaped pushing rod 822. The inner diameter of the pushing ring 821 is larger than the inner diameter of the rotating seat 51, and the outer diameter of the pushing ring 821 is smaller than the outer diameter of the rotating ring. The pushing ring 821 coaxially slides in the cylindrical wall of the rotating seat 51. The pushing rod 822 is fixed on the inner wall of the pushing ring 821 and extends radially along the rotating seat 51 to the through groove 14 of the rotating seat 51. The rotating seat 51 is provided with a giving way groove for the pushing rod 822 to allow the pushing rod 822 to move axially parallel to the rotating seat 51. The locking rod 81 is fixed to one end face of the pushing ring 821 facing the active seat 54, combined with Figure 4 A plurality of locking grooves 15 are evenly spaced along the circumference of the active seat 54 on the end surface of the active seat 54 facing the rotating seat 51. The locking grooves 15 correspond to the first limiting grooves 12 one by one, and the locking grooves 15 are used for the locking rods 81 to be inserted.

[0065] Reference Figure 5 and Figure 7 The second spring 83 is installed in the cylinder wall of the rotating seat 51 and is arranged in multiple numbers along the circumference of the rotating seat 51. One end of the second spring 83 is connected to the rotating seat 51, and the other end of the second spring 83 is connected to the push ring 821, and the axis of the second spring 83 is parallel to the axis of the rotating seat 51. The second spring 83 gives the locking rod 81 an elastic force to insert it into the locking groove 15 in the direction close to the active seat 54, so that the active seat 54 and the rotating seat 51 are relatively locked.

[0066] Reference Figure 4 and Figure 5 , when the second shaft 92 is located in the active seat 54, the locking rod 81 is inserted into the locking groove 15. When the second shaft 92 leaves the active seat 54 and is inserted into the rotating seat 51, the end of the second shaft 92 contacts the push rod 822 and pushes the push rod 822 away from the active seat 54, so as to drive the locking rod 81 to move in the direction away from the locking groove 15. When the telescopic end of the telescopic member 10 is fully extended, the locking rod 81 is completely separated from the locking groove 15, so that the active seat 54 and the rotating seat 51 are unlocked, and at this time, the output end of the power source 52 rotates to drive the rotating seat 51 to rotate relative to the active seat 54. What is more, after the power source 52 drives the rotating section to rotate and stop each time, each first limiting groove 12 corresponds to each second limiting groove 16 one by one and is connected to each other, and the locking rod 81 is opposite to one of the locking grooves 15, and the locking rod 81 is inserted into different locking grooves 15 to be able to adjust the angle of the fan blade 42 relative to the water surface.

[0067] Reference Figure 3, further, each blade 42 includes at least one leaf 421, and the leaf 421 is in the shape of a square plate. When the number of leaf 421 in the blade 42 is one, the leaf 421 is fixed to the outer wall of the rotating shaft 41. When the number of leaf 421 in the blade 42 is multiple, one leaf 421 is fixed to the outer wall of the rotating shaft 41, and the remaining leafs 421 are spliced ​​in sequence along the radial direction of the rotating shaft 41 and connected by fasteners 20. Specifically, each end of the leaf 421 has an extension piece extending outward, and when two adjacent leafs 421 are spliced ​​with each other, the two leafs 421 abut against each other and the extension pieces are opposite, and the fasteners 20 are bolts and nuts that cooperate with each other, and the bolts pass through the extension pieces of the two leafs 421 at the same time and are locked by the nuts to achieve the connection of the two leafs 421, and by adjusting the number of leafs 421 in the blade 42, the size of the leaf 42 can be adjusted, thereby adjusting the wave intensity.

[0068] Reference Figure 1 In addition, the wave-making mechanism 4 further includes a wind mechanism 17. The wind mechanism 17 includes a support frame 171 and a wind force member 172. The support frame 171 is erected at the end of the floating island 1, and the wind force member 172 is a wind turbine and has a plurality of wind force members 172. The plurality of wind force members 172 are distributed on the support frame 171 along the width direction of the floating island 1, so as to be able to blow air into the test cavity 2 to simulate a windy environment.

[0069] The implementation principle of a wave-making device in the embodiment of the present application is as follows: a floating island 1 is placed on the water surface, and a hull to be tested is placed in a test chamber 2. When performing a static water test, the wave-making device is stationary.

[0070] When performing a wave test, the telescopic member 10 is telescopically moved to drive the second shaft 92 to move to the active seat 54 or the rotating seat 51. When the second shaft 92 is located in the active seat 54, the magnetic force pushes the locking piece 71 to leave the active seat 54 to unlock the mounting seat 3 and the active seat 54. At this time, the output end of the power source 52 reciprocates to drive the driven seat 55 and the fan blades 42 to swing, so that the fan blades 42 push the water flow to generate waves. When the second shaft 92 is located in the rotating seat 51, the locking piece 71 re-locks the mounting seat 3 and the active seat 54, and the second shaft 92 pushes the locking rod 81 to leave the locking groove 15, so that the active seat 54 and the rotating seat 51 are unlocked. At this time, the output end of the power source 52 rotates cyclically to drive the rotating seat 51 to rotate, thereby driving the fan blades 42 to rotate along the axis of the rotating shaft 41 to beat and disturb the water flow to generate waves.

[0071] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
