Description

Technical Field

[0001] This invention relates to breakwater technology, belonging to the field of marine engineering, and specifically to a negative Poisson's ratio damping breakwater with shared mooring anchor connection and its usage method. Background Technology

[0002] A floating breakwater is a protective facility that floats on the sea surface. It uses the movement of the floating body to disturb waves and dissipate energy. Its role spans multiple dimensions, including wave energy buffering, infrastructure protection, marine resource utilization, and ecological balance maintenance. For example, in deep-sea aquaculture, large waves will affect the normal operation of the aquaculture area. Floating breakwaters can provide shelter for aquaculture cages, significantly reduce wind and wave loads, and improve the safety of aquaculture equipment and the survival rate of fish. Existing traditional floating breakwater box units generally suffer from prominent problems such as poor structural seismic and impact resistance, low wave energy dissipation efficiency, high cost of mooring systems and chaotic layout, making it difficult to meet the multi-functional needs of complex marine environments. Specifically, 1. From the perspective of wave dissipation and structural protection, existing breakwater hulls mostly adopt rigid connections or simple hinge designs. When facing the impact of waves with different periods and amplitudes, the impact of the wave action in different directions of the breakwater hulls will be concentrated at the connection points of adjacent breakwater hulls. The energy can only be passively buffered by the deformation of the connection points themselves, resulting in low wave energy absorption efficiency. Moreover, long-term alternating loads are prone to fatigue fracture at the connection points. Especially under extreme conditions such as typhoons and storm surges, collisions of breakwater hulls often cause local structural damage, significantly shortening their service life. 2. Traditional independent mooring mode requires a separate anchor chain for each unit, which not only increases the complexity of underwater construction and material costs, but also easily causes anchor chain entanglement due to relative displacement between units, reducing overall stability. 3. The marine environment is complex. Traditional floating breakwaters lack or have only a single shock-absorbing and energy-dissipating structure, making them unsuitable for different wave types. This increases the risk of breakwater damage when subjected to larger waves. Summary of the Invention

[0003] The purpose of this invention is to provide a negative Poisson's ratio shock-absorbing breakwater with shared mooring anchor connection. It has a simple structure and not only has high impact resistance, fracture resistance and structural toughness, but also has a longer service life. In addition, it can effectively buffer and reduce shock, reduce the risk of breakwater damage, and adapt to different coastline shapes and various breakwater protection needs.

[0004] To achieve the above objectives, a negative Poisson's ratio damping breakwater with shared mooring anchor connection is provided, comprising: Multiple floating tanks form a parallel linear, rectangular array, or circular closed-loop structure; Adjacent floating tanks are connected by connecting components; Each floating container has a negative Poisson's ratio structure and contains an internal bladder that fits against the inner wall of the floating container and can elasticate outward. The mooring anchor is connected to the bottom of multiple floating hulls by anchor chains; Among them, the adjacent floating tanks can provide elastic buffering within the space under the action of the connecting components.

[0005] In some examples of the present invention, the floating tank is a hexagonal shell structure with a concave center, and the connecting parts are connected to the four corners of the floating tank.

[0006] In some examples of the present invention, when multiple floating hulls form multiple parallel linear structures, the multiple floating hulls in the linear structure and the multiple floating hulls in the adjacent linear structure are all connected to the same mooring anchor. When multiple floating hulls form a rectangular array structure, multiple floating hulls in the same straight line are connected to the same mooring anchor, and multiple mooring anchors are arranged side by side; When multiple floating hulls form a circular closed loop structure, the center of the mooring anchor coincides with the center of the circular closed loop.

[0007] In some examples of the present invention, the connecting component has at least one connecting unit; The connecting unit has a connecting rod, a pair of support plates, and an elastic element; The elastic elements are installed on the support plate, which is fixed to the corresponding floating box. The two ends of the connecting rod are fixedly connected to the middle of the adjacent elastic elements.

[0008] In some examples of the present invention, the floating tank is provided with support rods on its periphery; The connecting component has at least one connecting unit; The connecting unit has a supporting cylinder, a support rod, a pair of elastic elements, and a chain link; A pair of chain links are movably mounted on adjacent support rods. Limiting rings are provided on both sides of the chain links to limit their movement. The limiting rings are threaded on the support rods. The shoulder of one end of the support rod slides inside the support cylinder, and one end extends to the outside and connects to one end of one of its chain links. The other end of the chain link is connected to one end of the support cylinder. A pair of elastic elements are located inside the support cylinder and on both sides of the support rod shoulder.

[0009] In some examples of the present invention, the floating tank is provided with support rods on its periphery; The connecting component has at least one connecting unit; The connecting unit includes a supporting cylinder, a support rod, a pair of elastic elements, and a winding drum; The shoulder of the support rod slides inside the support cylinder at one end and extends to the outside at the other end; a pair of elastic elements are located inside the support cylinder and are located on both sides of the shoulder of the support rod to achieve elastic balance. A pair of winding drums are fixed to adjacent support rods, enabling elastic winding of the rope. The rope is taut when one winding drum is connected to the support rod and the other winding drum is connected to the support cylinder.

[0010] In some examples of the invention, each floating tank is hinged to a wave-damping sway below it via a rigid traction rod; The weight of the wave-damping oscillating plate is greater than that of the floating tank.

[0011] In some examples of the present invention, the upper end of the traction rod is connected to the floating tank via a universal joint.

[0012] A method for using a negative Poisson's ratio damping breakwater with shared mooring anchor connections includes the following steps: S1, depending on the usage environment, multiple floating tanks with negative Poisson's ratio structures are spliced ​​together to form a parallel linear, rectangular array, or circular closed-loop structure; adjacent floating tanks are connected by connecting components to provide elastic buffering within the space; Multiple floating hulls are connected to the mooring anchor via anchor chains; S2, When subjected to small waves, the floating box can shrink and deform in the lateral and longitudinal directions, making the stress distribution more uniform, and the bladder inside the floating box is in a compressed state. When subjected to medium waves, the floating hull contracts and deforms while adjacent floating hulls move out of alignment, and the connecting components are repeatedly stretched and compressed to achieve energy superposition and dissipation under medium wave conditions. When subjected to large waves, the floating hull contracts and deforms and moves relative to its misalignment. At the same time, the breakwater swashplate connected to the bottom of the floating hull moves accordingly. The movement response of the breakwater swashplate lags behind that of the floating hull, inducing large-scale vortex shedding. A large amount of energy is consumed through fluid friction, reducing the risk of the breakwater being damaged by large winds and waves. Mooring anchors connected beneath multiple floating hulls help resist localized impacts and improve anchoring performance through shared nodes; S3, when subjected to small waves, the floating box returns to its initial state under the action of the capsule, and together dissipates the high-frequency low-energy waves.

[0013] Compared with existing technologies, this negative Poisson's ratio damping breakwater with shared mooring anchor connection has the following advantages: 1. The floating hull adopts a negative Poisson's ratio structure, which can undergo lateral and longitudinal contraction deformation simultaneously when subjected to wave pressure, making the stress distribution more uniform and avoiding local buckling instability. When the floating hull is subjected to the suction force of the waves, it can have a self-tensioning effect, which can inhibit the opening of cracks. It has high impact resistance, fracture resistance and structural toughness, and a longer service life. In addition, the floating hull is equipped with a bladder, which can be used for small wave conditions and filter high-frequency wave energy. 2. Adjacent floating hulls are connected by connecting components, which can provide elastic buffering in space, allowing adjacent floating hulls to consume a large amount of medium-frequency wave energy during repeated movement. This avoids damage caused by rigid bodies that cannot effectively consume wave energy, thus adapting to different coastline shapes and various wave protection needs. 3. A large-mass, hinged wave-breaking plate is installed below the floating hull. The wave-breaking plate and the floating hull form a compound pendulum structure, which generates significant phase lag under the impact of large waves. It can dissipate energy by utilizing fluid shape resistance, frictional resistance and wake vortex, avoid the wave resonance zone, and reduce the risk of the breakwater being damaged by large winds and waves. 4. Different floating hulls are connected to mooring anchors by anchor chains. On the one hand, this reduces the number of suction anchors or gravity anchors and lowers construction costs. On the other hand, structurally, the shared anchor chain network forms a geometric constraint. When a unit on one side is subjected to extreme wave thrust, the tension is distributed to the back unit and anchor point through the shared nodes. The mass of the overall array helps to resist local impacts and improves the anchoring performance of this negative Poisson's ratio shock-absorbing breakwater. This invention relates to a method for a negative Poisson's ratio damping breakwater with shared mooring anchor connections. It combines a floating box and bladder with a negative Poisson's ratio structure, connecting components, and breakwater swing plates to form a multi-stage damping and energy dissipation system suitable for waves of varying degrees, thus solving the problem of long wave reduction in traditional breakwaters.

[0017] like Figure 1 , Figure 3 As shown, this negative Poisson's ratio damping breakwater with shared mooring anchor connection includes: Multiple floating tanks 10 form a parallel linear or rectangular array or a circular closed-loop structure; Adjacent floating tanks 10 are connected by connecting components 20; Each floating container 10 has a negative Poisson's ratio structure and is equipped with a bladder 11 that fits against the inner wall of the floating container 10 and can be elastic outward. Mooring anchor 30 is connected to the bottom of multiple floating hulls 10 via anchor chain 31; Among them, under the action of the connecting component 20, the adjacent floating tanks 10 can perform elastic buffering within the space; Specifically, multiple floating hulls 10 constitute the main structure of this negative Poisson's ratio damping breakwater. Depending on the actual usage environment, they can be assembled to form a parallel linear, rectangular array, or circular closed-loop structure, such as... Figures 6 to 8 As shown; The floating box 10 is equipped with a bladder 11 inside. The bladder 11 can be an air bladder, which can increase the buoyancy of the negative Poisson's ratio shock-absorbing breakwater on the one hand, and act on the inner wall of the floating box 10 to make it subject to outward elastic force on the other hand. When using this negative Poisson's ratio type shock-absorbing breakwater, multiple floating boxes 10 are spliced ​​together by connecting parts 20; In the preferred embodiment, the floating box 10 is a hexagonal shell structure with a concave center. The connecting components 20 are connected to the four corners of the floating box 10. That is, the floating box 10 is a concave honeycomb negative Poisson's ratio structure. When the floating box 10 is subjected to wave pressure, it undergoes lateral and longitudinal contraction deformation simultaneously due to the negative Poisson's ratio effect. This active tightening deformation makes the stress distribution more uniform and avoids local buckling instability. When the floating box 10 is subjected to the suction force of the waves, the structure of the floating box 10 expands laterally, generating a self-tensioning effect that can inhibit the opening of cracks. The negative Poisson's ratio structure of the floating box 10 can autonomously deform and respond to the nature of the wave load, making the floating box 10 as a whole adaptive to multi-directional random loads of the ocean, enhancing structural toughness, and outperforming traditional floating boxes in terms of impact resistance and fracture resistance. Initially, the capsule 11 fills the floating box 10. When the floating box 10 contracts and deforms under wave pressure, it will continue to compress the capsule 11. When the wave trough arrives and the pressure on the floating box 10 decreases, the floating box 10 returns to its initial state under the action of the capsule 11. During this process, the capsule 11 enables the floating box 10 to recover its effectiveness in small wave conditions and can filter high-frequency wave energy. When waves act on this negative Poisson's ratio damping breakwater, the spatial phase change of the waves causes vertical displacement difference and lateral roll angle difference between adjacent hulls. The connecting component 20 can allow this controlled relative motion, so that the adjacent floating hulls 10 can be elastically buffered in space. This not only provides elastic restoring force to this negative Poisson's ratio damping breakwater, but also allows the adjacent floating hulls 10 to consume a large amount of mid-frequency wave energy during repeated displacement, avoiding damage caused by the inability of the rigid body to effectively consume wave energy.

[0018] Furthermore, such as Figures 6 to 8As shown, when multiple floating hulls 10 form multiple parallel linear structures, the multiple floating hulls 10 in the linear structure and the multiple floating hulls 10 in the adjacent linear structure are all connected to the same mooring anchor 30. When multiple floating hulls 10 form a rectangular array structure, multiple floating hulls 10 in the same straight line are connected to the same mooring anchor 30, and multiple mooring anchors 30 are arranged side by side. When multiple floating hulls 10 form a circular closed-loop structure, the center of the mooring anchor 30 coincides with the center of the circular closed-loop. Specifically, the mooring anchors 30 are set on the seabed and connected to different floating hulls 10 by anchor chains 31. That is, the anchor chains 31 are radially connected to different floating hulls 10. On the one hand, this can reduce the number of suction anchors or gravity anchors and reduce construction costs. On the other hand, structurally, the shared anchor chain network 31 forms a geometric constraint. When a unit on one side is subjected to extreme wave thrust, the tension is distributed to the back unit and anchor point through the shared nodes. The mass of the overall array is used to help resist local impacts and improve the anchoring performance of this negative Poisson's ratio shock-absorbing breakwater. For example, in a "double-row-lane" parallel alignment, the mooring anchor 30, as the central anchor point, can simultaneously hold six or more floating hulls 10; in a closed-loop structure smaller than a circle, the mooring anchor 30, as the central anchor point, can simultaneously hold eight or more floating hulls 10; in a rectangular array structure, the mooring anchor 30, as the central anchor point, can simultaneously hold three or more floating hulls 10 in the same direction.

[0019] Example 2 like Figure 3 , Figure 4 As shown, as a first example of the connecting member 20, the connecting member 20 has at least one connecting unit; The connecting unit has a connecting rod 23, a pair of support plates 21 and an elastic element 22; The elastic element 22 is installed on the support plate 21, which is fixed on the corresponding floating box 10. The two ends of the connecting rod 23 are fixedly connected to the middle of the adjacent elastic element 22. Specifically, the connecting component 20 may include two connecting units fixedly connected side by side; the elastic element 22 adopts a high stiffness coefficient shock-absorbing and energy-dissipating spring; the two ends of the spring are respectively connected to the support plate 21; The two ends of the connecting rod 23 can be spheres to facilitate embedding and connection between adjacent springs, or the two ends of the connecting rod 23 can be connected between adjacent springs by straps; When waves propagate through the breakwater array, adjacent floating hulls 10 will displace in different directions, thereby causing the elastic elements 22 to move in different directions. For example, when the floating hull 10 is swayed longitudinally by the waves, the elastic elements 22 in the connecting unit will extend and retract synchronously through the connecting rod 23, which can allow a certain amount of lateral and longitudinal roll angle difference. The high stiffness coefficient damping and energy dissipating spring can consume the medium-frequency wave energy by utilizing the material's hysteresis damping and mechanical friction, while multiple connecting parts 20 can form a huge flexible energy dissipating chain, making this negative Poisson's ratio damping breakwater suitable for medium-frequency waves.

[0020] like Figure 5 As shown, as a second example of the connecting component 20, the floating tank 10 is provided with support rods 24 around its periphery; The connecting component 20 has at least one connecting unit; The connecting unit has a supporting cylinder 25, a support rod 26, a pair of elastic elements 22 and a chain link 27; A pair of chain links 27 are movably mounted on adjacent support rods 24. Each of the chain links 27 has a limiting ring 28 threaded on the support rod 24 on both sides of the axial direction. The shoulder of one end of the support rod 26 slides inside the support cylinder 25, and the other end extends to the outside and is connected to one end of one of its chain links 27. The other chain link 27 is connected to one end of the support cylinder 25. A pair of elastic elements 22 are located inside the support cylinder 25 and on both sides of the shoulder of the support rod 26; Specifically, the connecting component 20 may have three connecting units; The floating box 10 is provided with an ear seat 12, and the support rod 24 is detachably installed on the ear seat 12; the chain link 27 is fitted on the support rod 24, which allows the chain link 27 to move in the vertical direction to a certain extent; the limiting ring 28 is threaded on the support rod 24, so that the connecting unit can be positioned on the support rod 24 and the vertical movement of the chain link 27 can be adjusted. The number of links in the chain 27 should not be too large to avoid excessive distance between adjacent floating tanks 10. The shoulder of the support rod 26 is in a balanced state under the action of a pair of elastic elements 22. Therefore, the chain 27 can be used for spatial misalignment of adjacent floating tanks 10. The elastic elements 22 in the support cylinder 25 can effectively provide elastic buffering for the movement of the support rod 26 during misalignment. Compared with the first example, the direction of the force of the elastic element 22 in this example is its own axis, which effectively avoids the elastic element 22 from deforming due to excessive misalignment angle, thus reducing the requirements for the performance of the elastic element 22.

[0021] As a third example of the connecting component 20, the floating tank 10 is provided with support rods 24 around its periphery; The connecting component 20 has at least one connecting unit; The connecting unit has a supporting cylinder 25, a support rod 26, a pair of elastic elements 22 and a winding drum; The shoulder of the support rod 26 slides inside the support cylinder 25 at one end and extends to the outside at the other end; a pair of elastic elements 22 are located inside the support cylinder 25 and are respectively located on both sides of the shoulder of the support rod 26 to achieve elastic balance. A pair of winding drums are fixed on adjacent support rods 24, which can elastically wind up the rope. The rope is taut and connected between one winding drum and support rod 26 and between the other winding drum and support cylinder 25. Specifically, the connecting component 20 may have three connecting units; The floating box 10 is provided with ear seat 12, and the support rod 24 is detachably installed on the ear seat 12; the winding drum is rotatably mounted on the support rod 24 and is wound up by a torsion spring, that is, the torsion spring is hidden inside the winding drum, one end is connected to the winding drum and the other end is connected to the support rod 24 so that the winding drum is subjected to torsion and the rope is wound up. In the initial state, under the winding action, the gap between adjacent floating tanks 10 is small, and the connecting units are relatively balanced. When the floating tanks 10 are displaced due to wave pressure, such as when adjacent floating tanks 10 move away from each other, the winding drum unwinds the rope. The rope can accommodate the spatial displacement of adjacent floating tanks 10. The elastic element 22 in the support cylinder 25 can effectively provide elastic buffering for the movement of the support rod 26 during the displacement process. Compared with the second example, in this example, the rope is wound up by the winding drum. In this state, the adjacent floating tanks 10 can maintain force balance. With the buffering effect of the elastic element 22, the problem of excessive swaying or even serious collision between the floating tanks 10 due to the influence of waves caused by the chain link 27 structure is avoided.

[0022] Example 3 like Figure 2 As shown, each floating tank 10 is hinged to a wave-damping sway plate 40 below it via a rigid traction rod 41. The weight of the wave-damping sway plate 40 is greater than that of the floating tank 10; Furthermore, the upper end of the traction rod 41 is connected to the floating tank 10 via a universal joint; Specifically, the breakwater pendulum 40 can be a cross-shaped flat plate of a specific mass, which is suspended below the floating box 10 with a negative Poisson's ratio structure by a traction rod 41, forming a compound pendulum structure with the floating box 10. The hinge direction allows the breakwater pendulum 40 to swing freely in the direction perpendicular to the breakwater line (front and back direction). When in a high-wave condition, the upper floating hull 10 moves violently with the waves, while the lower wave-breaking oscillating plate 40, due to its large mass (high inertia), lags behind the floating hull 10 in motion response. This phase difference causes the wave-breaking oscillating plate 40 to generate a violent relative velocity with the surrounding water. That is, the wave-breaking oscillating plate 40 has a specific mass and moment of inertia, and its natural frequency is much lower than the typical wave frequency, thus generating a significant phase lag under the impact of large waves. When the upper floating hull 10 moves with the waves, the lower wave-breaking oscillating plate 40 generates reverse or phase-shifting oscillations in the water, dissipating energy by utilizing fluid shape resistance, frictional resistance, and wake vortex. The oscillation of the breakwater 40 in the water triggers boundary layer separation and vortex shedding, converting wave kinetic energy into heat energy. This effectively increases the vertical added mass and rotational inertia of the breakwater, thereby adjusting the system's natural frequency, avoiding the wave resonance zone, and reducing the risk of damage to the breakwater from large winds and waves.

[0023] When using this type of negative Poisson's ratio damping breakwater with shared mooring anchor connection, the specific steps include: S1, depending on the usage environment, multiple floating tanks 10 with negative Poisson's ratio structures are spliced ​​together to form a parallel linear or rectangular array or a circular closed loop structure; adjacent floating tanks 10 are connected by connecting parts 20 to provide elastic buffering within the space. Multiple floating hulls 10 are connected to the mooring anchor 30 via anchor chains 31; S2, When subjected to small waves, the floating box 10 can shrink and deform in the lateral and longitudinal directions, making the stress distribution more uniform, and the bladder 11 inside the floating box 10 is in a compressed state. When subjected to medium-sized waves, the wavelength is relatively long. While the floating box 10 contracts and deforms, the adjacent floating boxes 10 move relative to each other. The connecting parts 20 are repeatedly stretched and compressed to achieve energy superposition and dissipation under medium-sized wave conditions. When subjected to large waves, the wave kinetic energy is enormous. While the floating box 10 contracts and deforms and moves relative to the displacement, the breakwater sway plate 40 connected to the bottom of the floating box 10 moves along with it. The movement response of the breakwater sway plate 40 lags behind that of the floating box 10, inducing a large-scale vortex shedding. A large amount of energy is consumed through fluid friction, reducing the risk of the breakwater being damaged by large winds and waves. The mooring anchors 30 connected below multiple floating hulls 10 assist in resisting localized impacts and improving anchoring performance through shared nodes; S3, when subjected to small waves, the floating box 10 returns to its initial state under the action of the capsule 11, and together dissipates the high-frequency low-energy waves.

However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the concept of this invention, and various combinations can be made to the various technical features and structures proposed in this invention, without exceeding the protection scope of this invention, which is determined by the appended claims.

A method of using a negative Poisson's ratio damping breakwater with shared mooring anchor connection according to claim 7, characterized in that, Specifically, the following steps are included: S1, depending on the usage environment, multiple floating tanks (10) with negative Poisson ratio structures are spliced ​​together to form a parallel linear or rectangular array or a circular closed loop structure; adjacent floating tanks (10) are connected by connecting parts (20) to provide elastic buffering in space; Multiple floating hulls (10) are connected to the mooring anchor (30) via anchor chains (31); S2, when subjected to small waves, the floating box (10) can shrink and deform in the lateral and longitudinal directions, making the stress distribution more uniform, and the bladder (11) inside the floating box (10) is in a compressed state. When subjected to medium waves, the floating box (10) contracts and deforms while the adjacent floating boxes (10) move relative to each other, and the connecting parts (20) are repeatedly stretched and compressed to achieve energy superposition and dissipation under medium wave conditions. When subjected to large waves, the floating box (10) shrinks and deforms and moves relative to the displacement. At the same time, the wave-breaking plate (40) connected to the bottom of the floating box (10) moves accordingly. The movement response of the wave-breaking plate (40) lags behind that of the floating box (10), inducing large-scale vortex shedding. A large amount of energy is consumed through fluid friction, reducing the risk of the breakwater being damaged by large winds and waves. The mooring anchors (30) connected below multiple floating hulls (10) assist in resisting local impacts and improving anchoring performance through shared nodes; S3, when subjected to small waves, the floating box (10) returns to its initial state under the action of the capsule (11), and together dissipates the high-frequency low-energy waves.
