[0029] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0030] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0031] like Figure 1 and Figure 4 As shown, a wave-blocking device for deep-sea cages according to this application includes a floating unit 1, a wave-blocking plate 2, an anchoring frame 3, reinforcing connectors 4, and a wave-guiding inclined plate 5. The functions and structural designs of each component are described in detail below:

[0032] The floating unit 1 provides buoyancy to support the overall structure of the wave-breaking device. It is designed as a hollow cavity structure 11 (see details). Figure 3This structure significantly reduces the overall weight of the device by reducing material volume, thereby reducing the load on the anchoring system. The outer surface of the floating unit 1 is made of a multi-layer composite material, typically composed of glass fiber or carbon fiber combined with high-performance polymer resin, which effectively improves fatigue resistance and corrosion resistance. Furthermore, the floating units 1 are connected by a flexible hinge structure 12, enabling adjustable multi-angle installation. This allows the device to adapt its angle in wave environments, avoiding structural fatigue failure due to a single fixed position.

[0033] The primary function of the wave deflector 2 is to reduce wave impact and provide a protective barrier for the entire system. It is assembled to the floating unit 1 via bolts, ensuring ease of assembly and disassembly and improving maintenance efficiency. To meet high strength requirements, the wave deflector 2 can be made of high-quality alloy steel with an anti-corrosion coating to extend its service life. Furthermore, the design of the wave deflector 2 should fully consider water flow distribution characteristics; for example, adjusting the shape of the deflector surface to optimize the absorption and dispersion of wave energy further enhances the stability of the system.

[0034] The function of the anchoring frame 3 is to secure the entire wave-breaking device to the seabed. The anchoring frame 3 is connected to the floating unit 1 by high-strength cables and is stably positioned on the seabed either by being driven into the seabed or by ballast weights. This connection method can withstand external forces such as ocean currents and wind, while ensuring that the floating unit 1 does not shift or capsize excessively. Specifically, the anchoring frame 3 can be prefabricated from steel or concrete to adapt to different water conditions.

[0035] The reinforcing connector 4 is used to strengthen the connection between the floating units 1 and provides a certain degree of elastic deformation capability to mitigate the instantaneous force peaks caused by wave impact. The reinforcing connector 4 can be implemented using metal spring sheets or other elastic material components, which still have strong recovery capabilities under extreme sea conditions without permanent deformation. These components are generally made by precision injection molding or heat treatment technology to enhance the toughness of the material, ensuring the stability of the connection while giving the device the necessary flexibility, thereby improving the long-term reliability of the device.

[0036] The wave guide ramp 5 is located at the outer edge of the wave deflector 2, and its main function is to guide the wave flow and reduce direct impact. The guide ramp is usually welded and fixed to the wave deflector 2 at an inclined angle, and the structural integrity and connection strength are ensured by adjusting the welding process parameters. Specifically, the surface of the ramp is roughened or textured to reduce the possibility of vortices generated by the friction between the waves and the surface of the device, thereby further improving the efficiency of wave energy flow management.

[0037] The above design scheme addresses the issue of enhancing fatigue resistance through a comprehensive approach: First, the outer surface of floating unit 1 utilizes multi-layered composite materials, whose excellent mechanical strength combined with high elongation at break significantly improves the components' tolerance to frequent load fluctuations. Second, the design of the connecting parts between floating units 1 is enhanced, using components with elastic deformation capabilities to absorb excess stress and prevent fatigue cracking that may occur with traditional rigid connections. Third, the implementation of flexible hinge technology on floating unit 1 improves installation flexibility and reduces repeated local stress concentrations caused by rigid constraints. Finally, the optimized wave guide ramp 5 adjusts the impact direction, thereby reducing the probability of force transmission to weak points in the device. In summary, these improvements, through multiple dimensions including material selection, structural layout, and mechanical transmission, effectively enhance the fatigue resistance of the wave-blocking device.

[0038] like Figure 2 As shown, in one embodiment, the floating unit 1 of the deep-sea cage wave-blocking device of this application has a specific support structure inside to optimize the overall strength. Specifically, this support structure is achieved by adding several transversely and longitudinally arranged support ribs 6, which are installed inside the hollow cavity structure 11 of the floating unit 1 to form an intersecting grid-like layout. This design not only effectively enhances the internal mechanical properties of the floating unit 1, but also avoids the adverse effects on weight caused by adding extra materials, while maintaining the advantages of its external fatigue resistance multilayer composite material.

[0039] Specifically, during the manufacturing process, pre-formed support ribs 6 are embedded one by one into the hollow cavity and fixed in their respective positions by gluing or welding, ensuring a stable connection between the support ribs 6 and the hollow cavity. For example, the support ribs 6 are made of high-strength lightweight alloys or composite fibers, which can reduce their own weight while ensuring mechanical properties, thus not affecting the overall buoyancy performance and dynamic adjustment function of the floating unit 1. This assembly method facilitates large-scale industrial production and allows for easy adjustment of the number and size distribution of the support ribs 6 according to specific application scenarios.

[0040] like Figure 5 As shown, in one embodiment, the flexible hinge connection structure 12 of the deep-sea cage wave-blocking device of this application is used to realize multi-angle adjustment between floating units 1. This structure mainly includes two parts: a hinge shaft 7 and an elastic sleeve 8. One end of the hinge shaft 7 is installed inside the floating unit 1, and the other end passes through the elastic sleeve 8 and connects to the adjacent floating unit 1. The elastic sleeve 8 is made of a flexible polymer material and is sleeved on the outside of the hinge shaft 7, ensuring the integrity of the structure through a tight fit. Furthermore, the hinge shaft 7 has an axial limiting structure to ensure that the components will not loosen or shift during assembly, thereby maintaining the stability of the connection.

[0041] Specifically, the inner and outer surfaces of the elastic sleeve 8 are specially treated to provide excellent compression and cushioning capabilities under wave action. For example, in a scenario with large wave amplitude, when waves cause the floating unit 1 to shift at a certain angle, the elastic sleeve 8 can deform and absorb excess energy. Simultaneously, the hinge shaft 7 allows adjacent floating units 1 to rotate relative to each other at a certain angle, thereby giving the wave-blocking device better adaptability and resilience. This structural design ensures a robust connection between the floating units 1 and enhances the device's responsiveness to complex marine environments.

[0042] like Figure 5 As shown, in one embodiment, the outer surface of the floating unit 1 of the deep-sea cage wave-blocking device of this application is made of multi-layer composite material. This design can improve the fatigue resistance of the entire structure in the marine environment. Since the floating unit 1 operates under wave impact and complex sea conditions for a long time, its external material must possess excellent mechanical properties and corrosion resistance. Specifically, the outer layer uses a surface anti-corrosion coating 9 to prevent the effects of salt spray, moisture, and other corrosive factors, while the inner layer is an internal fiber reinforcement layer 10 to provide overall strength and toughness. The two combine to form a composite material structure. This multi-layer composite material is tightly attached to the outer surface of the floating unit 1, and a precise manufacturing process ensures a strong bond between the layers.

[0043] For example, during production, the structure can be constructed by first laying a fiber-reinforced layer on the outside of the hollow cavity structure 11 of the floating unit 1, and then covering it with an anti-corrosion coating 9. During installation, the composite material must be uniformly coated or fixed to the outer surface of the floating unit 1 to avoid performance differences caused by local thicknesses that are too thin or too thick. After connecting the wave deflector 2 to the floating unit 1 with bolts, it can be further ensured that the outer surface protected by the composite material is not affected by construction, thus fully preserving its fatigue resistance advantages. Specifically, the flexible hinge connection structure 12 allows the floating unit 1 to adapt to multi-angle adjustment needs during use, while the composite material maintains its integrity in this position.

[0044] like Figure 4 As shown, in one embodiment, the bolt connection of a wave-blocking device for deep-sea cages according to this application is specially equipped with an anti-loosening washer 13 to ensure the stability of the connection. The anti-loosening washer 13 is disposed between the floating unit 1 and the wave-blocking plate 2, located at an appropriate position on the bolt tightening path, effectively preventing bolt loosening due to vibration in the marine environment or long-term water flow impact. Specifically, the anti-loosening washer 13 achieves its tightening effect by increasing the frictional resistance of the connection, and its surface has a specific textured structure to further enhance the connection effect. This design, combined with the fixing relationship between the bolts, the floating unit 1, and the wave-blocking plate 2, provides reliable performance in deep-sea environments.

[0045] For example, the anti-loosening washer 13 can be manufactured from a suitable thickness of elastic metal material and fitted into the groove between the bolt and the contact end of the floating unit 1. During assembly, precise alignment of the components is required to ensure uniform force transmission. Simultaneously, the torque value is measured when the bolts are pre-tightened to determine if the installation meets the predetermined standards, ensuring a stable connection between the wave deflector 2 and the floating unit 1. In this arrangement, the anti-loosening washer 13 and the connectors together form a reliable fastening system.

[0046] like Figure 1 As shown, in one embodiment, the anchoring frame 3 of a deep-sea cage wave-blocking device of this application is provided with a dedicated shock-absorbing node 14. This node is used to optimize the connection between the cable and the floating unit 1 and to effectively distribute the tension. Specifically, by installing the shock-absorbing node 14 at the key stress-bearing parts of the anchoring frame 3, the tension generated by wave impact and the swaying of the floating unit 1 can be redistributed through this node. This node is usually located in the upper region of the anchoring frame 3 to facilitate the smooth passage of the cable while maintaining proper contact with the surrounding structure to avoid stress concentration.

[0047] The damping node 14 is made of a high-polymer elastic material, with regularly distributed buffer cavities inside, which are in direct contact with the cable, serving to absorb energy and transmit force. The exterior is covered with a metal reinforcing ring to improve its wear resistance and ensure a secure connection with the anchoring frame 3. During assembly, the damping node 14 can be fixed to the anchoring frame 3 by threaded locking or welding.

[0048] For example, a high-strength and elastic rubber material can be selected to construct the damping node 14, which is then embedded into a pre-drilled groove on the anchoring frame 3, and stability is ensured by positioning bolts. The two ends of the cable are fixed to the floating unit 1 and the seabed base, respectively, while the middle portion passes through the perforations in the damping node 14 to distribute the tension. This design helps to mitigate the frequent vibrations of the floating unit 1 caused by wave impacts.

[0049] like Figure 6As shown, in one embodiment, the reinforcing connector 4 of the deep-sea cage wave-blocking device of this application further enhances the overall impact resistance through structural improvements. The reinforcing connector 4 adopts a double-layer structure design. Specifically, the inner layer is a rigid support ring 15, which is located between the connecting floating units 1 and bears the main support function, while limiting the amplitude of elastic deformation to ensure the positional stability between components. The outer flexible sheath 16 surrounds the rigid support ring 15. Its material selection has high energy absorption capacity and ductility to alleviate the instantaneous load concentration phenomenon caused by wave or water flow impact. There is no direct mechanical fixing relationship between the two parts, but they rely on precise dimensional matching to achieve a tight fit, thereby forming a complete reinforcing connector 4.

[0050] Specifically, a high-strength and high-modulus metal material (such as titanium alloy) can be selected to make the rigid support ring 15, and its shape can be ensured by molding. At the same time, a seawater-resistant polymer composite material (such as ultra-high molecular weight polyethylene) can be selected as the material for the flexible sheath 16, which is injection molded and fitted onto the outside of the rigid support ring 15. During the installation process, the reinforcing connector 4 is first embedded into the predetermined area between the floating units 1, and preliminary assembly is carried out with the help of snaps or embedded positioning grooves to ensure that the inner and outer structures are aligned and stably fixed at the connection point.

[0051] like Figure 5 As shown, in one embodiment, the outer surface of the floating unit 1 of the deep-sea cage wave-blocking device of this application has multiple sets of protrusions 18 evenly distributed. The specific installation positions of these protrusions 18 are located in various directions outside the floating unit 1, ensuring coverage of the entire outer surface and a balanced distribution. This structural design, through the multiple sets of protrusions 18 forming a micro-rough region, optimizes the spatial distribution of water flow resistance. From a material composition perspective, the protrusions 18 and the outer surface of the floating unit 1 are entirely composed of the same multi-layered composite material, thereby achieving a synergistic improvement in fatigue resistance. Its unique geometric structure further influences the local eddy current formation trend, reducing the accumulation of random vibration energy caused by wave impact.

[0052] Specifically, each protrusion 18 of the floating unit 1 is arranged in a regular pattern, such as an array layout or a polygonal partitioned embedded design, and is stably connected to the outer surface of the main body using an integrated molding process. For example, injection molding or compression molding can be used to firmly bond the protrusions 18 to the outer surface of the floating unit 1. This implementation method preserves the overall lightweight characteristics of the floating unit 1 without significantly increasing manufacturing difficulty or assembly complexity. With this structure, the force of wave impact is further dispersed to more contact points, reducing structural wear and tear during long-term use.

[0053] like Figure 4As shown, in one embodiment, a counterweight 19 is fixedly installed on the back of the wave-blocking plate 2 of a deep-sea cage wave-blocking device of this application. The counterweight 19 is connected to the wave-blocking plate 2 through an appropriate installation method. The main function of the counterweight 19 is to optimize the buoyancy distribution of the overall structure by fine-tuning its position, thereby improving the stability of the device. Specifically, the counterweight 19 is usually made of high-density material and its length or weight can be adjusted according to actual needs to adapt to different operating environments and sea conditions. To achieve this characteristic, the counterweight 19 needs to be accurately installed in the central or side areas of the back of the wave-blocking plate 2, and in some cases, it can also be designed in a modular form for easy replacement.

[0054] For example, the counterweight 19 can be securely installed on a specific area on the back of the wave deflector 2 using screws, clips, or adhesive. To further enhance fatigue resistance, the counterweight 19 may be made of fiber-reinforced composite material with an outer anti-corrosion coating. In practice, the optimal balance of overall buoyancy can be achieved by precisely controlling the mass distribution of the counterweight 19 and combining it with the hollow cavity design of the floating unit 1.

[0055] like Figure 5 As shown, in one embodiment, the reinforcing connector 4 of the deep-sea cage wave-blocking device of this application is connected to the floating unit 1 via a slot 20, which optimizes both adjustability and stability. Specifically, the reinforcing connector 4 is disposed on the external structure of the floating unit 1 and is embedded into a pre-designed opening on the floating unit 1 via the slot 20. The rigid material of the reinforcing connector 4 and the design of the connection part with the floating unit 1 enable it to provide support, while the application of multi-layer composite materials provides better fatigue resistance and durability for the entire structure.

[0056] For example, the insertion operation can be completed by prefabricating a standard-sized interface at one end of the reinforcing connector 4 and aligning it with the slot reserved in the floating unit 1. Then, it can be further tightened by the rotary locking member 21 installed on the reinforcing connector 4. The function of the locking member is to apply an appropriate preload by rotating and adjusting to control its tightness, thereby adapting to the elastic deformation requirements caused by the repeated impact of waves in the marine environment, while ensuring a firm connection between the components.

[0057] like Figure 5As shown, in one embodiment, the floating unit 1 of a deep-sea cage wave-blocking device of this application is provided with sliding rails 17 on both sides. These sliding rails 17 provide conditions for slidable assembly, allowing adjacent floating units 1 to be connected by physical contact. The sliding rails 17 are typically made of durable materials and have undergone surface treatment to reduce frictional resistance and the possibility of corrosion. The sliding rails 17 are arranged on the sides of the floating unit 1, forming a long strip guide rail area, ensuring that two floating units 1 can be precisely aligned and tightly connected in a predetermined direction. At the same time, this design retains a flexible installation method, allowing the wave-blocking device to adapt to complex sea conditions in different scenarios.

[0058] Structurally, the sliding track 17 consists of a base plate and protruding guide edges, where the guide edges define the relative positions between the floating units 1 to ensure directional stability and alignment accuracy during sliding. Furthermore, the connection between the floating units 1 requires a locking component to fix their position after sliding. This locking component may include bolt holes or a quick-release latch system for easy operation and adjustment. For example, locking is achieved by a locking pin embedded in the sliding track 17, thereby preventing the floating units 1 from loosening under external forces.

[0059] Specifically, this sliding track 17 can be integrated into the main body of the floating unit 1 using casting or welding techniques, ensuring its integral nature with the floating unit 1. During actual manufacturing, it is necessary to ensure a smooth transition between the track plane and the sidewall of the floating unit 1 to avoid unnecessary stress concentration problems in a wave environment.

[0060] In actual operation, when this device is in use, the floating unit 1 is fixed to the seabed by the anchoring frame 3 and maintained in a stable position by cable connections. When waves impact the wave-blocking plate 2, the wave-guiding ramp 5 guides the waves to change direction, thereby reducing the direct impact force on the device. The reinforcing connector 4 plays an elastic deformation role in this process, buffering the wave force and reinforcing the connection between the floating units 1 to prevent structural loosening. The floating unit 1 has fatigue resistance due to the multi-layer composite material on its outer surface, and its weight is reduced through the hollow cavity structure 11. Under the action of the flexible hinge connection structure 12, it can achieve multi-angle adjustment, ensuring that the device can adapt to the needs of different sea conditions.

[0061] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this application.
