Detailed implementation manners

[0037] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be described in more detail below with reference to the attached drawings in the preferred embodiments of the present utility model.

[0038] As Figure 1 shown, an embodiment of the present utility model provides a wave-making device, which is applied to a floating body experimental wave-making pool, and includes a base 1; a wave-making component 2, which is rotatably connected to the base 1, the wave-making component 2 includes a wave-making part 21, the wave-making part 21 includes a flow port 211 for liquid to flow through, and the wave-making part 21 can be deformed to change the flow area of the flow port 211; a first driving part 3, which is arranged on the base 1 and is used to drive the wave-making component 2 to rotate relative to the base 1; the rotation direction of the wave-making component 2 corresponds to the flow direction of the flow port 211.

[0039] Among them, the rotation direction of the wave-making component 2 corresponds to the flow direction of the flow port 211, which can be understood as that when the wave-making component 2 rotates relative to the base 1 to generate waves, the liquid can flow through the flow port 211.

[0040] In the wave-making device provided by the embodiment of the present utility model, the wave-making assembly 2 includes a wave-making part 21 which can deform to change the flow area of its flow port 211, and the first driving part 3 can drive the wave-making assembly 2 to rotate relative to the base 1, so as to generate waves in the liquid in the wave-making pool. Since the flow area of the flow port 211 of the wave-making part 21 can change during the wave-making process, the wave-making device can generate various forms of waves, enabling the wave-making device to simulate various wave forms, adapt to different hydrodynamic requirements, and thus improving the authenticity and application range of the wave-making device in simulating ocean waves, so as to better meet and adapt to the research needs of different test scenarios.

[0041] In some embodiments, the wave-making part 21 may include a wave-making body and a second driving part. The wave-making body can deform and includes the aforementioned flow port 211; the second driving part is connected to the wave-making body and is used to drive the wave-making body to deform.

[0042] During the process of the first driving part 3 driving the wave-making assembly 2 to rotate relative to the base 1, the second driving part can drive the wave-making body to deform, so that the flow area of the flow port 211 changes, thereby obtaining various forms of waves.

[0043] Among them, the structural form of the wave-making body can be various, as long as it can deform to change the size of the flow area of the flow port 211. For example, the wave-making body may include two U-shaped pipe bodies which are inserted and buckled with each other, and a flow port 211 is formed between the two pipe bodies. The two can move relative to each other under the drive of a driving mechanism, thereby changing the flow area of the flow port 211.

[0044] For the convenience of use, in some embodiments, referring to Figure 2 and Figure 3 , the wave-making body may include a first connecting rod 212, a second connecting rod 213, a third connecting rod 214 and a fourth connecting rod 215 which are sequentially hinged and enclose a ring; moreover, the first connecting rod 212, the second connecting rod 213, the third connecting rod 214 and the fourth connecting rod 215 enclose the aforementioned flow port 211.

[0045] Since the first connecting rod 212, the second connecting rod 213, the third connecting rod 214 and the fourth connecting rod 215 are sequentially hinged, relative displacement can be generated between the first to fourth connecting rods 215 under the action of an external force, enabling the wave-making body to expand and contract, thereby changing the shape of the wave-making body and further changing the flow area of the flow port 211 surrounded by it. The structure is simple, the operation is convenient, and the use is reliable.

[0046] In some embodiments, the number of wave-making bodies can be one or more; if the number of wave-making bodies is more than one, the multiple wave-making bodies are sequentially connected in series.

[0047] In some embodiments, referring to Figure 2 and Figure 3 , the wave-making assembly 2 may further include a first bracket 22, and the first bracket 22 may be a frame structure; the second driving part may include a first limiting rod 216 and a second driving body, the second driving body is disposed on the first bracket 22, and the second driving body is connected to the first limiting rod 216; the hinge shafts of the first connecting rod 212 and the second connecting rod 213 are connected to the first limiting rod 216; the hinge shafts of the third connecting rod 214 and the fourth connecting rod 215 are connected to the first bracket 22; the second driving body is configured to drive the first limiting rod 216 to move relative to the first bracket 22, so as to drive the wave-making body to deform.

[0048] In the above embodiments, the first limiting rod 216 can move relative to the first bracket 22 under the drive of the second driving body, so as to drive the first connecting rod 212 and the second connecting rod 213 to move relative to the bracket, and further trigger the linkage of the first to fourth connecting rods 215, so as to change the overall shape of the wave-making body, and further change the flow area of the flow port 211 surrounded by the first to fourth connecting rods 215.

[0049] Among them, the structural form of the second driving body can be various, as long as it can drive the first connecting rod 212 to move relative to the first bracket 22. For example, the second driving body may include a motor, a gear and a rack, the rack extends along the moving direction of the first limiting rod 216, the gear is meshed with the rack, one end of the gear is connected to the motor, and the other end is rotatably connected to the first limiting rod 216 to realize the gear driving the first limiting rod 216 to move. Alternatively, the second driving body may be a telescopic rod, and its telescopic direction is the same as the moving direction of the first limiting rod 216, and the telescopic end of the telescopic rod is connected to the first limiting rod 216 to realize driving the first limiting rod 216 to move during the telescopic process.

[0050] Among them, the number of the first limiting rods 216 may be two, and the two first limiting rods 216 are disposed oppositely.

[0051] In some embodiments, referring to Figure 2 and Figure 3 , the wave-making assembly 2 may further include a second limiting rod 217, the second limiting rod 217 is movably disposed on the first bracket 22, the second limiting rod 217 is parallel to the first limiting rod 216, a chute or through hole 2171 extending along its length direction is formed on the second limiting rod 217, and the moving direction of the second limiting rod 217 is the same as the moving direction of the first limiting rod 216; the hinge shafts of the first connecting rod 212 and the fourth connecting rod 215, and the hinge shafts of the second connecting rod 213 and the third connecting rod 214 are movably inserted into the chute or through hole 2171.

[0052] During the movement of the first limiting rod 216 relative to the first bracket 22, the second limiting rod 217 will be displaced along with the first limiting rod 216. At the same time, the hinge axes of the first connecting rod 212 and the fourth connecting rod 215, and the hinge axes of the second connecting rod 213 and the third connecting rod 214 slide in the chute or through hole 2171, so that the second limiting rod 217 can play a role in positioning the wave-making body. Especially when the number of wave-making bodies is multiple, the second limiting rod 217 can keep multiple wave-making bodies stretching and contracting stably along with the first limiting rod 216, so that the wave-making body deforms stably.

[0053] Specifically, there are various implementation manners for movably arranging the second limiting rod 217 on the first bracket 22. For example, a chute is arranged on the first bracket 22, and the end of the second limiting rod 217 is slidably connected to the chute. Moreover, the number of the second limiting rods 217 can be two, and the two second limiting rods 217 are arranged oppositely.

[0054] In some embodiments, referring to Figure 1 and Figure 4 , the first driving part 3 may include a first driving body 31 and a transmission mechanism 32. The first driving body 31 is connected to the transmission mechanism 32, and the transmission mechanism 32 is connected to the wave-making assembly 2. The first driving body 31 is used to drive the wave-making assembly 2 to rotate relative to the base 1 through the transmission mechanism 32.

[0055] In some embodiments, referring to Figure 1 and Figure 4 , the transmission mechanism 32 may include a second bracket 321, an eccentric wheel 322, a fifth connecting rod 323, a sixth connecting rod 324, and a sliding rod 325. The second bracket 321 is arranged on the base 1, the eccentric wheel 322 is rotatably connected to the second bracket 321. A first sliding hole 3231 extending along the length direction is formed in the fifth connecting rod 323, and a second sliding hole 3241 extending along the length direction is formed in the sixth connecting rod 324. One end of the fifth connecting rod 323 is rotatably connected to the second bracket 321, and the other end of the fifth connecting rod 323 is slidably connected to the second sliding hole 3241 through a first slider 326. The sixth connecting rod 324 is connected to the sliding rod 325, and the sliding rod 325 is slidably arranged on the second bracket 321 along its length direction. The eccentric wheel 322 is slidably connected to the first sliding hole 3231 through a second slider 327; the sliding rod 325 is movably connected to the wave-making assembly 2; the first driving body 31 is connected to the eccentric wheel 322.

[0056] In the above embodiments, the first driving body 31 drives the eccentric wheel 322 to rotate. The first slider 326 slides in the sliding hole, and the second slider 327 slides in the second sliding hole 3241, so that the fifth connecting rod 323 and the sixth connecting rod 324 drive the sliding rod 325 to reciprocate along its length direction, thereby driving the wave-making assembly 2 to rotate relative to the base 1, realizing wave-making for the liquid in the wave-making pool.

[0057] During a complete rotation cycle of the eccentric wheel 322, the eccentric wheel 322 pushes the sliding rod 325 forward through the fifth connecting rod 323 and the sixth connecting rod 324 to drive the wave-making assembly 2 to rotate away from the base 1, and this stroke is the forward stroke. The eccentric wheel 322 pulls the sliding rod 325 backward through the fifth connecting rod 323 and the sixth connecting rod 324 to drive the wave-making assembly 2 to rotate towards the base 1, and this stroke is the return stroke. Among them, the forward stroke of each slider occupies a larger part of the rotation angle of the eccentric wheel 322, while the return stroke is completed within the remaining smaller angle of the rotation angle of the eccentric wheel 322. During the forward stroke (working stroke), the sliding rod 325 moves at a slower speed. After completing the forward stroke, the sliding rod 325 quickly pulls back the wave-making assembly 2 to reduce the time used for the return stroke (non-working stroke), thereby reducing the non-working time and improving the working efficiency.

[0058] That is to say, the transmission mechanism 32 has a quick-return characteristic, and the speed of the return stroke of each slider is greater than that of the forward stroke, thereby reducing the return stroke time and improving the working efficiency.

[0059] In some embodiments, referring to Figure 1 , the first driving body 31 may include a motor and a speed reducer. The output end of the motor is connected to the input end of the speed reducer, and the output end of the speed reducer is connected to the eccentric wheel 322.

[0060] Among them, the speed reducer can be a two-stage speed reducer, which is used to reduce the rotational speed of its input end and provide a larger output torque, thereby facilitating the driving of the wave-making assembly 2 by the first driving part 3, and further facilitating the improvement of the wave-making effect of the wave-making device.

[0061] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3, the wave-making assembly 2 may further include a first bracket 22, on which a third sliding hole 221 is formed. Specifically, the third sliding hole 221 may be provided at the top of the first bracket 22, and the extending direction of the third sliding hole 221 corresponds to the rotation direction of the wave-making assembly 2 relative to the base 1; on the outer wall of the end of the sliding rod 325, a first limiting protrusion 3251 and a second limiting protrusion 3252 are provided, and the first limiting protrusion 3251 and the second limiting protrusion 3252 are arranged along the length direction of the sliding rod 325; the end of the sliding rod 325 passes through the third sliding hole 221, and the first limiting protrusion 3251 and the second limiting protrusion 3252 are respectively located at both ends of the third sliding hole 221.

[0062] Wherein, under the limiting action of the first limiting protrusion 3251 and the second limiting protrusion 3252, the sliding rod 325 can slide in the third sliding hole 221, so as to ensure that the wave-making assembly 2 rotates stably relative to the base 1 under the driving action of the first driving part 3, making it more convenient to use.

[0063] The embodiment of the present invention also provides a floating body experimental wave pool, including the aforementioned wave-making device.

[0064] Since the floating body experimental wave pool provided by the embodiment of the present invention includes the wave-making device, therefore, the floating body experimental wave pool has all the beneficial effects of the wave-making device, which will not be elaborated here.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
