Description

Technical Field

[0001] This application relates to the field of wave-damping device technology, and in particular to a reversible wave-damping beach with wave-damping mode and upright mode. Background Technology

[0002] Test pools are typically used to simulate the propagation, reflection, and dissipation of ocean waves. To reduce wave reflections after they reach the pool walls, test pools usually have breakwaters on the side opposite the wave-generating equipment. Specifically, a breakwater is a wave-absorbing facility used to absorb wave energy and reduce the impact of reflected waves. It generally has an inclined surface, a curved surface, or a composite slope, allowing waves to climb, break up, and dissipate their energy along its surface.

[0003] In practical applications, breakwaters are generally configured as detachable structures. When wave dissipation is needed, the breakwater is installed at the appropriate location in the pool, utilizing its sloping or curved surface to absorb wave energy; when wave dissipation is no longer required, the breakwater is removed and taken out of the pool. In other words, breakwaters are primarily used for wave dissipation when installed, and are usually idle after removal, exhibiting a single function and cumbersome operation due to repeated disassembly, assembly, and relocation. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a reversible breakwater with both a wave-dissipating mode and an upright mode, in order to solve the problems of existing breakwaters having a single function and being cumbersome to operate due to repeated disassembly, assembly and transportation.

[0005] To achieve the above technical objectives, this application provides a reversible breakwater with a wave-damping mode and an upright mode, comprising: a support base, a movable plate, and a drive mechanism;

[0006] The support base is fixedly installed, and the upper side of the support base is a fixed wave-damping surface;

[0007] The movable plate is located on the front side of the support base facing the test water area, and the movable plate has a working surface;

[0008] The end of the movable plate away from the support base can be flipped and mounted on the installation base;

[0009] The end of the movable plate near the support base is connected to the drive mechanism;

[0010] The drive mechanism is used to rotate the movable plate so that the movable plate can switch between a wave-damping mode and an upright mode.

[0011] In the wave-damping mode, the upper side of the movable plate is the working surface, and the working surface is connected to the fixed wave-damping surface to form a continuous wave-damping surface;

[0012] In the upright mode, the side of the moving plate facing the test water area forms an upright boundary.

[0013] Furthermore, the end of the movable plate away from the support base is rotatably mounted on the mounting base via a rotating shaft;

[0014] The driving mechanism is used to drive the end of the movable plate near the support to rotate around the rotation axis, so that the movable plate can flip between the wave-damping position and the upright position.

[0015] In the upright mode, the movable plate flips up to stand upright on the working surface, so that the side of the movable plate facing the test water area forms the upright boundary.

[0016] Furthermore, the working surface is a plane.

[0017] Furthermore, the driving mechanism is a traction mechanism.

[0018] Furthermore, the drive mechanism includes: a winch, a first traction rope, and a second traction rope;

[0019] Both the first traction rope and the second traction rope are wound on the winch;

[0020] The first traction rope and / or the second traction rope have elastic telescopic sections;

[0021] The first traction rope and the second traction rope are wound in opposite directions;

[0022] The outer end of the first traction rope is connected to one side of the moving plate;

[0023] The outer end of the second traction rope is connected to the other side of the moving plate;

[0024] The winch rotates the moving plate by winding up and unwinding the first and second traction ropes.

[0025] Furthermore, both the first traction rope and the second traction rope are elastic ropes.

[0026] Furthermore, the first traction rope and the second traction rope are elastic rubber core braided ropes or double-layered nylon braided ropes.

[0027] Furthermore, the drive mechanism includes: a winch, a first traction rope, and a second traction rope;

[0028] The winch is connected to a first drum and a second drum;

[0029] The first traction rope is wound around the first drum;

[0030] The second traction rope is wound around the second drum;

[0031] The first drum and the second drum have different effective winding diameters to compensate for the difference in length change between the first traction rope and the second traction rope during the flipping of the moving plate.

[0032] Furthermore, it also includes: a front-end limiting mechanism and a rear-end limiting mechanism;

[0033] The front-end limiting mechanism and the rear-end limiting mechanism are fixedly installed;

[0034] In the wave-damping mode, the lower side of the movable plate abuts against the rear limiting mechanism;

[0035] In the upright mode, the working surface of the moving plate abuts against the front limiting mechanism.

[0036] Furthermore, the front-end limiting mechanism and / or the rear-end limiting mechanism are hydraulic buffer columns, pneumatic buffer columns, or elastic buffer columns.

[0037] Furthermore, it also includes: positioning mechanisms;

[0038] The positioning mechanism can move between the positioning position and the avoidance position;

[0039] When the locking mechanism is in the locking position, the locking mechanism is used to restrict the moving plate from switching between the upright mode and the wave-damping mode;

[0040] When the positioning mechanism is in the avoidance position, the positioning mechanism avoids the movement trajectory of the moving plate, so as to allow the moving plate to switch between the wave-damping mode and the upright mode.

[0041] Furthermore, it also includes the supporting structure;

[0042] The positioning mechanism is disposed on the support structure;

[0043] The support base and the movable plate are disposed below the support structure;

[0044] The locking mechanism is a retractable pin;

[0045] When the locking mechanism is in the locking position, the retractable pin extends to restrict the movable plate in the upright mode between the retractable pin and the front limiting mechanism;

[0046] When the locking mechanism is in the avoidance position, the retractable pin retracts to avoid the movement trajectory of the moving plate.

[0047] Furthermore, the reversible wave-damping beach is positioned at the boundary of the test pool along the first direction;

[0048] The reversible wave-damping beach is configured to switch to the upright mode when the test pool generates waves in the second direction;

[0049] The first direction intersects with or is perpendicular to the second direction.

[0050] Furthermore, the test pool is provided with a plurality of reversible wave-damping beaches along the boundary position of the first direction;

[0051] Each of the aforementioned reversible breakwaters is driven by multiple drive mechanisms;

[0052] Flexible seals or overlap plates are provided between adjacent movable plates;

[0053] As can be seen from the above technical solutions, this application provides a reversible wave-damping beach with wave-damping mode and upright mode, including: a support base, a movable plate, and a driving mechanism; the support base is fixedly installed, and the upper side of the support base is a fixed wave-damping surface; the movable plate is installed on the front side of the support base facing the test water area, and the movable plate has a working surface; the end of the movable plate away from the support base is reversibly installed on the mounting base; the end of the movable plate near the support base is connected to the driving mechanism; the driving mechanism is used to drive the movable plate to rotate.

[0054] In this design, the movable plate can switch between wave-damping mode and upright mode. In wave-damping mode, the working surface of the movable plate connects with the fixed wave-damping surface of the support base to form a continuous wave-damping surface, allowing waves to rise, break up, and dissipate energy along the continuous wave-damping surface, thereby achieving the conventional wave-damping function and reducing the impact of reflected waves on the test water area. In upright mode, the movable plate flips to form an upright boundary, transforming the original arc-shaped or sloping wave-damping boundary facing the test water area into a boundary shape close to the upright pool wall.

[0055] This solution enables rapid switching between wave-damping and vertical boundaries by flipping the movable plate, eliminating the need for frequent disassembly or transport of the entire wave-damping beach. This reduces the operational difficulty of switching operating conditions in large test pools, improves testing efficiency, and enhances the adaptability of the same test pool to different wave-generating conditions.

[0056] Furthermore, when the breakwater does not need to participate in wave dissipation, but the test pool generates waves in other directions, switching the non-working breakwater to a vertical boundary can reduce the interference of the breakwater surface or slope structure on wave propagation, improve the consistency of the pool boundary conditions, and enhance the wave field quality, wave height distribution stability, and the validity of the test data.

Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments in this application specification, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection claimed in this application.

For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0080] Please see Figures 1 to 8This application provides a reversible wave-dissipating beach with both wave-dissipating and upright modes, which can be applied to a test pool 10. The test pool 10 contains a test water area for conducting experiments. The test pool 10 can be a deep-water test pool or a shallow-water test pool; the test pool 10 can be a rectangular pool, a square pool, or other wave-generating test pool with at least one boundary location. Wave generators can be installed on one or more sides of the test pool 10, and correspondingly, a wave-dissipating beach is installed on the side opposite the wave generator.

[0081] In this embodiment, the reversible wave-damping beach includes: a support base 1, a movable plate 2, and a drive mechanism 3; the support base 1 is fixedly installed, and its upper side is a fixed wave-damping surface 11. In practical applications, the support base 1 can be installed at the boundary of the test pool 10, specifically fixed to the pool bottom, pool wall, or pool edge foundation. The fixed wave-damping surface 11 can be an arc-shaped surface, a sloping surface, a curved surface, a composite slope, or a wave-damping surface formed by splicing multiple wave-damping units. The fixed wave-damping surface 11 can guide waves to rise, break up, fall back, and dissipate energy.

[0082] The movable plate 2 is positioned on the front side of the support base 1 facing the test water area, and the movable plate 2 has a working surface 21. The end of the movable plate 2 away from the support base 1 can be flipped and mounted on the mounting foundation 9. The mounting foundation 9 on which the movable plate 2 is mounted can be the pool bottom, pool wall, or pool edge foundation. The end of the movable plate 2 closest to the support base 1 is connected to the drive mechanism 3. The drive mechanism 3 can rotate the movable plate 2, allowing it to switch between wave-damping mode and upright mode.

[0083] In wave-damping mode, the movable plate 2 is driven to the lowered position by the drive mechanism 3. At this time, the upper side of the movable plate 2 serves as the working surface 21, which connects with the fixed wave-damping surface 11 of the support base 1, thus forming a continuous wave-damping surface. When waves propagate to the reversible wave-damping beach, they can first pass through the working surface 21 of the movable plate 2 and then climb up along the fixed wave-damping surface 11 of the support base 1. At this time, the reversible wave-damping beach can play the role of a conventional wave-damping beach under the test conditions that require wave damming, reducing the impact of reflected waves on the target wave field in the test water area.

[0084] In upright mode, the drive mechanism 3 drives the movable plate 2 to flip upwards, switching it from a lowered position to an upright or near-upright position. At this time, the side of the movable plate 2 facing the test water area forms an upright boundary, transforming the movable plate 2, originally serving as the front of the wave-damping front, into a boundary structure similar to a normal pool wall. This upright boundary serves to block water and act as a wall.

[0085] During installation, the installation position of the reversible wave-damping beach can be determined based on the wave-generating and wave-dissipating directions of the test pool 10. For example, if a wave generator is installed on one side of the test pool 10, and the waves generated by the wave generator need to be dissipated from the opposite side, the reversible wave-damping beach can be installed on the side opposite to the wave generator. When wave dissipation is required, the reversible wave-damping beach switches to wave-dissipating mode, at which point the waves generated by the wave generator can be transmitted to the continuous wave-dissipating surface so that the waves can be dissipated. When wave dissipation is not required, the reversible wave-damping beach switches to upright mode, at which point the movable plate 2 forms an upright boundary, allowing the movable plate 2 to act as a boundary wall.

[0086] It should be noted that when the test pool 10 has multiple wave-generating directions, that is, when the test pool 10 has multiple wave generators on multiple sides and multiple wave-dissipating beaches on the opposite sides of the wave generators, the reversible wave-dissipating beach can be installed at one of the boundary positions, so that it switches to wave-dissipating mode when wave dissipation is needed at that boundary, and switches to upright mode when wave dissipation is not needed at that boundary, so that the wave-dissipating beach that is not used in the test pool 10 will not affect the wave generation in other directions.

[0087] Specifically, multiple pool boundaries are set in the test pool 10. If wave generators are installed on multiple boundaries of the test pool 10, different operating conditions can be tested by controlling the start and stop of the wave generators on different boundaries. This allows for the generation of various wave conditions, such as unidirectional wave generation, bidirectional wave generation, oblique wave generation, cross waves, or composite waves, within the same test pool 10, to meet the needs of different marine engineering model tests and wave propagation tests. By constructing the test pool 10, the operating condition coverage and utilization rate of the test pool 10 can be improved, reducing the need to repeatedly construct multiple dedicated pools for different test conditions.

[0088] In practical applications, the direction from boundary d to boundary b is taken as the first direction, such as... Figure 4 The y-axis direction in the diagram; the direction from boundary a to boundary c is taken as the second direction, such as... Figure 4 The x-axis direction is shown in the figure. In this embodiment, the reversible wave-damping beach is configured to be located at the boundary position of the test pool along the first direction, that is, on boundary d or boundary b. The reversible wave-damping beach is configured to switch to an upright mode when the test pool generates waves along the second direction.

[0089] Specifically, such as Figure 4As shown, taking the experimental pool 10 as a rectangular pool with four boundaries a, b, c, and d respectively, wave generators can be installed on adjacent boundaries a and b, and breakwaters can be installed on adjacent boundaries c and d. In unidirectional wave generation mode, wave generators are activated only on one side of boundaries a and b. For example, if the wave generator on boundary a is activated, the breakwater on the opposite side boundary c will undertake the main wave-damping function, while the breakwaters on other boundaries (boundary d) will not undertake the main wave-damping function. In this case, the inventors have found through analysis that, because the breakwaters have a wave-damping surface, even when they are not in operation and the wave-damping surface is not directly facing the wave generation direction, they will still affect the wave effect, thereby changing the morphology of the water boundary on that side, and thus affecting wave propagation, wave height distribution, or wave field stability.

[0090] In this embodiment, the wave-dissipating beach that does not need to perform wave-dissipating function can be switched to the upright mode. For example, when the wave generator on boundary a is generating waves in the unidirectional wave-generating mode, the wave-dissipating beach on boundary d is switched to the upright mode, so that the boundary position is changed from the wave-dissipating slope boundary to the upright boundary, thereby reducing the interference of the wave-dissipating beach on wave generation in other directions under non-wave-dissipating conditions.

[0091] Therefore, the reversible breakwater in this embodiment can not only be used for storage or to reduce disassembly and assembly, but also allows the same breakwater to have two different pool boundary forms. It can quickly switch between a breakwater boundary and an upright boundary in the test pool 10, improving the adaptability of the test pool 10 to different wave-generating conditions and improving wave field quality, wave height distribution consistency, and test result reproducibility. Therefore, the reversible breakwater provided in this embodiment is particularly suitable for test pools 10 where multiple boundaries are equipped with wave generators. In such test pools 10, when a wave generator on a certain boundary is working alone, the breakwater that does not need to perform wave-damping functions can be switched to an upright mode, transforming the moving plate 2 of the breakwater at that boundary location into an upright boundary close to a normal pool wall. This helps reduce the interference of the non-working side breakwater on the wave field in the current wave-generating direction, improving the boundary adaptability and test accuracy of the multi-boundary wave-generating test pool 10 under different conditions such as unidirectional wave generation, bidirectional wave generation, oblique wave generation, or cross wave generation.

[0092] Furthermore, in this embodiment, by folding the end of the movable plate 2 away from the support base 1 onto the mounting base 9, the rotating end of the movable plate 2 can be positioned at the front end of the foldable wave-dissipating slope facing the test water area. This allows the movable plate 2 to rotate upwards around its front end as the rotation center when switching from wave-dissipating mode to upright mode, directly forming an upright boundary on the side of the movable plate 2 facing the test water area. Compared to hinged connection of the end of the movable plate 2 near the support base 1, this embodiment sets the rotating end of the movable plate 2 away from the support base 1, which avoids creating a large clearance space or gap area in front of the support base 1 after the movable plate 2 is folded. This ensures that the movable plate 2 remains positioned on the side of the support base 1 facing the test water area in upright mode, thus better shielding or replacing the original front boundary of the wave-dissipating slope. In other words, in this embodiment, the movable plate 2 does not simply leave the wave-dissipating position after folding, but rather forms an upright boundary close to the pool wall on the side of the test water area, thus better achieving the switch from wave-dissipating boundary to upright boundary. Meanwhile, since the rotating end of the movable plate 2 is set on the mounting base 9 instead of directly on the support base 1, the self-weight load, wave impact load and driving load generated during the rotation of the movable plate 2 can be transferred to the mounting base 9 more, reducing the structural impact on the support base 1 and the fixed wave-damping surface 11, which is conducive to maintaining the installation stability of the support base 1 and the morphological stability of the fixed wave-damping surface 11.

[0093] In another specific embodiment, the test pool 10 can be a combined deep and shallow test pool. Unlike the test pool 10 described above, as... Figure 5 As shown, the test pool 10 in this embodiment may include a deep pool 101 and a shallow pool 102. The deep pool 101 and the shallow pool 102 are arranged adjacent to each other and can be connected. The deep pool 101 is used to form a deep-water wave-generating test area, and the shallow pool 102 is used to form a shallow-water propagation test area, so as to simulate the process of wave propagation from the deep water area to the shallow water area, nearshore area or tidal flat area.

[0094] In this combined deep-shallow test pool, the deep pool 101 can have multiple boundaries. Taking a rectangular deep pool 101 with four boundaries a, b, c, and d as an example, boundary a is adjacent to boundary b, boundary a is opposite to boundary c, and boundary b is opposite to boundary d. Boundaries a and b can each be equipped with wave generators, allowing the deep pool 101 to generate waves in different directions according to test requirements. Boundary c can be located close to the shallow pool 102, serving as a boundary of the shallow pool 102. On the shallow pool 102, a conventional removable wave-damping beach or the reversible wave-damping beach provided in this embodiment can be installed near boundary c; a reversible wave-damping beach of this embodiment can be installed at boundary d.

[0095] During the experiment, the wave generators on boundaries a and b can be selectively activated individually or simultaneously. For example, when the wave generator on boundary a is activated alone, a wave-damping beach can be set up at boundary c, or wave damping can be achieved by the shallow pool 102, depending on the experimental purpose; the reversible wave-damping beach at boundary d can switch between wave-damping mode and upright mode depending on whether it performs the main wave-damping function. When the wave generator on boundary b is activated alone, the reversible wave-damping beach at boundary d can switch to wave-damping mode to perform the main wave-damping function. When the wave generators on boundaries a and b are activated simultaneously, the reversible wave-damping beach at boundary d can select the corresponding state according to the target wave field, wave-damping requirements, and boundary consistency requirements.

[0096] Through the above methods, this embodiment enables the test pool to meet various experimental requirements within a limited space, including independent wave generation in the deep water pool 101, multi-directional wave generation in the deep water pool 101, deep-to-shallow water propagation, boundary wave dissipation, and boundary verticalization. Compared to traditional fixed wave-dissipating beaches, this embodiment does not require frequent disassembly and reassembly of the large wave-dissipating beach at boundary d between different test conditions. Instead, it achieves rapid switching between wave-dissipating and vertical modes by flipping the movable plate 2, thereby reducing the difficulty of switching between test conditions in the large test pool 10.

[0097] Based on the above, the reversible wave-damping beach provided in this embodiment is applicable to test pools with both deep and shallow water sections. Such test pools require the wave-damping beach to absorb waves under certain operating conditions, while also minimizing changes to boundary conditions by the non-operating side wave-damping beach during deep-to-shallow water propagation or wave generation in adjacent directions. This embodiment, by placing the reversible wave-damping beach on one side of the boundary of the non-connected shallow water section 102 within the deep water section 101, and enabling it to switch between wave-damping and upright modes, can improve the adaptability of the combined deep-shallow test pool to different test conditions while retaining fixed wave-damping capabilities. It also reduces interference from the non-operating side wave-damping beach on wave propagation, improves wave field quality, wave height distribution consistency, and the reproducibility of combined deep-shallow propagation test results.

[0098] In one embodiment, the end of the movable plate 2 furthest from the support base 1 is rotatably mounted on the mounting base 9 via a rotating shaft 4; the rotating shaft 4 can extend along the width direction of the movable plate 2, allowing the movable plate 2 to rotate around the rotating shaft 4 as the rotation center. A drive mechanism 3 is connected to the end of the movable plate 2 closest to the support base 1 to drive the movable plate 2 to rotate between a wave-damping position and an upright position.

[0099] In wave-damping mode, the movable plate 2 rotates to the wave-damping position, with its working surface 21 facing upwards and connecting with the fixed wave-damping surface 11 to form a continuous wave-damping surface. In upright mode, the drive mechanism 3 drives the movable plate 2 to rotate upwards around the rotation axis 4 to the upright position, so that the working surface 21 of the movable plate 2 is in an upright or nearly upright state. At this time, the side of the movable plate 2 facing the test water area forms an upright boundary, thereby switching the reversible wave-damping beach from a wave-damping boundary to an upright boundary close to the pool wall.

[0100] In one embodiment, the working surface 21 is a plane. Specifically, when the moving plate 2 is in the wave-damping mode, the working surface 21 serves as the leading guide surface of the continuous wave-damping surface, which can connect with the fixed wave-damping surface 11 to guide the waves to gradually transition from the test water area to the fixed wave-damping surface 11, thereby helping the waves to climb along the continuous wave-damping surface and dissipate energy.

[0101] When the movable plate 2 is in the upright mode, since the working surface 21 is flat, after the movable plate 2 is flipped to the upright position, the working surface 21 can form a relatively flat upright boundary. Compared with curved surfaces, concave and convex surfaces, or irregular curved surfaces, the flat working surface 21 is closer to the boundary shape of a normal pool wall in the upright state. This helps to reduce the additional influence of the wave-dissipating beach on the water boundary conditions in the non-working state, thereby improving the boundary consistency and wave field stability of the test pool when generating waves in other directions.

[0102] Meanwhile, setting the working surface 21 as a plane also has the advantages of simple structure, convenient processing, easy cleaning and maintenance, and helps the moving plate 2 to obtain a more stable boundary shape when switching between wave-damping mode and upright mode.

[0103] In one embodiment, the drive mechanism 3 is a traction mechanism. Specifically, the traction mechanism can be connected to the moving plate 2 via a traction rope, traction belt, chain, or other traction component, and can rotate the moving plate 2 by retracting or extending the traction component. Compared to directly installing a large push-pull mechanism underwater, the traction mechanism allows the main power components to be arranged at the pool edge, above the pool wall, or other easily maintainable locations, which helps reduce the underwater installation space occupied and reduces the impact of water erosion or wave impact on the drive mechanism 3.

[0104] In a more specific embodiment, the drive mechanism 3 includes a winch 31, a first traction rope 32, and a second traction rope 33. Both the first traction rope 32 and the second traction rope 33 are wound on the winch 31, and their winding directions are opposite. The outer end of the first traction rope 32 is connected to one side of the moving plate 2, and the outer end of the second traction rope 33 is connected to the other side of the moving plate 2. At least one of the first traction rope 32 and the second traction rope 33 has an elastic telescopic section.

[0105] In practical use, when the winch 31 rotates in the first direction, it can tighten the first traction rope 32 and release the second traction rope 33, thereby pulling the moving plate 2 to flip in one direction via the first traction rope 32; when the winch 31 rotates in the second direction, it can tighten the second traction rope 33 and release the first traction rope 32, thereby pulling the moving plate 2 to flip in the opposite direction via the second traction rope 33. Thus, the winch 31 can drive the moving plate 2 to switch between the wave-damping position and the upright position through the coordinated winding and unwinding of the first traction rope 32 and the second traction rope 33.

[0106] In this embodiment, the above structure enables bidirectional tilting control of the moving plate 2 based on a single winch 31, reducing the number of drive components and making the structure more compact. Furthermore, the first traction rope 32 and the second traction rope 33 are respectively connected to both sides of the moving plate 2, providing traction and constraint to both sides during the tilting process, making the movement of the moving plate 2 smoother and reducing the possibility of swaying due to wave action, self-weight, or inertia. It should be noted that the support base 1 may be provided with a clearance opening (not shown in the figure) to avoid the traction ropes.

[0107] And, as Figure 6 As shown, when the moving plate 2 rotates around its rotating end, the movement trajectories of the connection positions of the first traction rope 32 and the moving plate 2 and the second traction rope 33 and the moving plate 2 are different. Therefore, the distance changes of the two connection positions relative to the winch 31 are inconsistent, resulting in a difference in the actual winding and unwinding lengths of the two traction ropes.

[0108] The drive mechanism 3 includes a first traction wheel 34 and a second traction wheel 35; a first traction rope 32 is wound around the first traction wheel 34 and connected to one side of the moving plate 2; a second traction rope 33 is wound around the second traction wheel 35 and connected to the other side of the moving plate 2. In the wave-damping mode, the length of the connection point between the first traction rope 32 and the moving plate 2 and the first traction wheel 34 is S1, and the length of the connection point between the second traction rope 33 and the moving plate 2 and the second traction wheel 35 is L1. In the upright mode, the length of the connection point between the first traction rope 32 and the moving plate 2 and the first traction wheel 34 is S2, and the length of the connection point between the second traction rope 33 and the moving plate 2 and the second traction wheel 35 is L2.

[0109] During the switching between wave-damping mode and upright mode of the moving plate 2, the length change of the first traction rope 32 is S1-S2; the length change of the second traction rope 33 is L2-L1. Due to the different arrangement positions, connection positions, and spatial relationships of the two traction ropes relative to the rotation center of the moving plate 2, the difference between L2 and L1 is not equal to the difference between S1 and S2. The difference ΔD in the required amount of take-up and release for the two ropes is: Wherein, ΔL is L2-L1; ΔS is S1-S2. In this embodiment, ΔL is greater than ΔS, that is, the amount of winding and unwinding of the second traction rope 33 is greater than the amount of winding and unwinding of the first traction rope 32.

[0110] Specifically, when the first traction rope 32 and the second traction rope 33 are wound in opposite directions on the same winch 31, the theoretical winding and unwinding lengths of the two traction ropes corresponding to a certain angle of rotation of the winch 31 are the same or basically the same. However, the actual length changes required for the two traction ropes during the flipping of the moving plate 2 are different. Therefore, when the first traction rope 32 and the second traction rope 33 are rigid traction ropes, one traction rope may become over-tensioned.

[0111] This embodiment enables at least one of the first traction rope 32 and the second traction rope 33 to have an elastic extension section, allowing the elastic traction rope to elongate or retract during the flipping of the moving plate 2. This compensates for the difference in the actual length changes of the two traction ropes, thereby maintaining the two traction ropes in an appropriate tension state. This allows the moving plate 2 to flip smoothly between the wave-damping position and the upright position, while reducing the impact load borne by the connection between the traction ropes, the winch 31, and the moving plate 2.

[0112] In one implementation, at least one of the first traction rope 32 and the second traction rope 33 can be configured as an integral elastic extension section, meaning the entire rope is elastic, for example, using an elastic rubber core braided rope or a full nylon double-layer braided rope. The elastic rubber core braided rope can generate elastic extension and contraction through its internal rubber core, and provides abrasion resistance and tensile strength protection through its outer braided layer; the full nylon double-layer braided rope can utilize the elongation properties of the nylon material itself to compensate for the length difference between the two traction ropes.

[0113] In another embodiment, at least one of the first traction rope 32 and the second traction rope 33 may be configured to include a rigid section and an elastic section. For example, if the first traction rope 32 has an elastic telescopic section, the end of the first traction rope 32 that connects to the moving plate 2 is configured as an elastic telescopic section (the length of the elastic telescopic section can be adjusted according to the actual situation), and the other part is configured as a rigid section.

[0114] In this embodiment, an elastic component connection is used, which eliminates the need for the entire traction rope to be made of elastic material. This approach can provide local elastic compensation at the connection point while preserving the load-bearing capacity and dimensional stability of the traction rope itself, and also facilitates the inspection and replacement of the elastic component.

[0115] In another embodiment, the drive mechanism 3 includes a winch 31, a first traction rope 32, and a second traction rope 33. The winch 31 is connected to a first drum and a second drum. The first traction rope 32 is wound on the first drum, and the second traction rope 33 is wound on the second drum. The winding directions of the first traction rope 32 and the second traction rope 33 are opposite. The first drum and the second drum have different effective winding diameters to compensate for the difference in length change between the first traction rope 32 and the second traction rope 33 during the flipping process of the moving plate. When the winch 31 rotates, one of the first traction ropes 32 and the second traction rope 33 is retracted, and the other traction rope is released, thereby driving the moving plate 2 to flip between the wave-damping position and the upright position.

[0116] In this embodiment, the first and second drums have different effective winding diameters, resulting in different rope winding and unwinding lengths at the same rotation angle. For example, if the winding and unwinding amount of the second traction rope 33 is greater than that of the first traction rope 32, the diameter of the first drum is smaller than that of the second drum. In practical applications, the ratio of the effective winding diameters of the first and second drums can be set according to the ratio of ΔS to ΔL. By using different drum diameters to compensate for the length difference of the two traction ropes during the flipping process of the moving plate 2, the excessive tension or slack of the traction ropes is reduced, thus eliminating the need for elastic traction ropes.

[0117] In other embodiments, two independently controlled winches can be provided to achieve differential control of the winding and unwinding of the first traction rope 32 and the second traction rope 33.

[0118] In one embodiment, the reversible breakwater further includes a front limiting mechanism 5 and a rear limiting mechanism 6; the front limiting mechanism 5 and the rear limiting mechanism 6 are fixedly arranged, and can be fixed on the aforementioned mounting base 9, or fixed on a bracket on the mounting base 9.

[0119] In wave-damping mode, the lower side of the movable plate 2 abuts against the rear limiting mechanism 6. The rear limiting mechanism 6 can restrict the movable plate 2 from continuing to rotate downward and support the movable plate 2, keeping the working surface 21 in the position of connecting with the fixed wave-damping surface 11, thereby ensuring the shape stability of the continuous wave-damping surface. The rear limiting mechanism 6 can also bear part of the self-weight of the movable plate 2 and the load of the waves acting on the movable plate 2, reducing the force required by the drive mechanism 3 to continuously maintain the position of the movable plate 2.

[0120] In the upright mode, the working surface 21 of the movable plate 2 abuts against the front limiting mechanism 5. The front limiting mechanism 5 can restrict the movable plate 2 from continuing to rotate and determine the upright position of the movable plate 2, so that the movable plate 2 can stably form an upright boundary on the side facing the test water area.

[0121] In application, one front-end limiting mechanism 5 and one rear-end limiting mechanism 6 can be set, or multiple mechanisms can be set at intervals along the width direction of the moving plate 2, so as to uniformly support and limit different positions of the moving plate 2 and reduce the tilting or deformation of the moving plate 2 due to local stress.

[0122] In one implementation, the rear limiting mechanism 6 may include a buffer post. When the movable plate 2 flips to the wave-damping mode, it contacts the buffer post and gradually presses down on the buffer post as it flips. When the buffer post reaches its minimum stroke or preset position, the movable plate 2 stops flipping and limits the final position of the movable plate 2 in the wave-damping mode with this stroke position, so that the buffer post simultaneously achieves buffering and limiting.

[0123] In one implementation, the rear limiting mechanism 6 may include a buffer column and a rigid support column. When the movable plate 2 flips to the wave-damping mode, the movable plate 2 first contacts the buffer column, and gradually presses down on the buffer column during the flipping process. Finally, the movable plate 2 flips to abut against the rigid support column, which supports and positions the movable plate 2. That is, in this embodiment, the buffer column can reduce the impact generated by the flipping of the movable plate 2, and the rigid support column provides support for the movable plate 2.

[0124] In one implementation, the front limiting mechanism 5 and / or the rear limiting mechanism 6 are hydraulic buffer columns, pneumatic buffer columns, or elastic buffer columns. Taking a hydraulic buffer column as an example, the hydraulic buffer column may include a fixed cylinder and a buffer rod that can extend and retract relative to the fixed cylinder. When the moving plate 2 approaches the wave-damping position or the upright position, the moving plate 2 first contacts the buffer rod and pushes the buffer rod to retract. The hydraulic buffer column gradually absorbs the kinetic energy of the moving plate 2 through hydraulic damping.

[0125] In one embodiment, such as Figure 7 and Figure 8 As shown, the reversible breakwater also includes: a locking mechanism 7; the locking mechanism 7 can move between a locking position and a avoidance position; when the locking mechanism 7 is in the locking position, it restricts the moving plate 2 from switching between an upright mode and a breakwater mode, thereby keeping the moving plate 2 in its current working position and preventing it from overturning due to wave impact or water flow disturbance. When the locking mechanism 7 is in the avoidance position, it avoids the movement trajectory of the moving plate 2, at which time the moving plate 2 can switch between a breakwater mode and an upright mode.

[0126] In practical applications, the locking mechanism 7 can be moved between the locking position and the avoidance position by means of electric drive or other means. After the movable plate 2 switches to the upright mode, the locking mechanism 7 extends to the locking position to limit the movement of the movable plate 2. By setting the locking mechanism 7, the movable plate 2 can be kept in the upright mode, and its stability is improved by the mechanical limiting effect provided by the locking mechanism 7.

[0127] As one implementation, a support structure 8 can be provided on the mounting base 9. The support structure 8 can serve as a mounting support component for the aforementioned winch 31, front-end limiting mechanism 5, and other components. In this embodiment, the locking mechanism 7 is provided on the support structure 8; the support base 1 and the movable plate 2 are provided below the support structure 8; the locking mechanism 7 is a retractable pin; when the locking mechanism 7 is in the locking position, the retractable pin extends to restrict the movable plate 2 in the upright mode between the retractable pin and the front-end limiting mechanism 5; when the locking mechanism 7 is in the avoidance position, the retractable pin retracts to avoid the movement trajectory of the movable plate 2.

[0128] In this embodiment, the retractable pin can be driven by a mechanism such as an electric push rod, a hydraulic cylinder, or a pneumatic cylinder.

[0129] As one implementation method, such as Figure 7 As shown, the position of the movable plate 2 in the upright mode is defined as the upright position. The locking mechanism 7 can be configured behind the upright position. After the movable plate 2 moves to the upright position, the front end of the movable plate 2 abuts against the front limiting mechanism 5, and the rear end abuts against the locking mechanism 7, so that the movable plate 2 is limited and fixed.

[0130] In another implementation, such as Figure 8 As shown, the movable plate 2 may be provided with a slot for the locking mechanism 7 to engage; when the movable plate 2 moves to the upright position, the locking mechanism 7 engages in the slot so that the movable plate 2 is fixed in place.

[0131] In one embodiment, multiple reversible wave-dissipating beaches are generally configured at the boundary of the test pool. Each reversible wave-dissipating beach is equipped with a support base 1, a movable plate 2, and a drive mechanism 3. Among the multiple reversible wave-dissipating beaches located on the same boundary, the multiple support bases 1 can be connected into a whole. Each reversible wave-dissipating beach is driven by multiple drive mechanisms 3 respectively. Each reversible wave-dissipating beach is equipped with an independent rotating shaft 4, a front limiting mechanism 5, a rear limiting mechanism 6, and a locking mechanism 7.

[0132] Among the multiple movable plates 2, a flexible seal or an overlap plate can be provided between adjacent movable plates 2; wherein, the flexible seal or overlap plate can be based on existing technology, and therefore will not be described in detail in this embodiment.

[0133] In this embodiment, by setting multiple reversible wave-damping surfaces, the size, weight, and required driving force of a single movable plate 2 can be reduced, facilitating manufacturing, transportation, installation, and maintenance. The connection of multiple support bases 1 into a whole improves the structural continuity and installation stability between the reversible wave-damping surfaces. Each movable plate 2 is driven by a corresponding drive mechanism 3, allowing each reversible wave-damping surface to switch independently according to test conditions, and also facilitating the repair of locally faulty units. Flexible seals or overlapping plates are provided between adjacent movable plates 2 to compensate for gaps caused by positional deviations during the reversal process, reducing abrupt changes in water volume or boundaries, and enabling the multiple movable plates 2 to jointly form a relatively continuous boundary surface in both wave-damping and upright modes.

[0134] The above are merely preferred embodiments of this application and are not intended to limit the present invention. Although this application has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
