The offshore wind and wave resistant anchoring device comprises a ship anchor and an anchor chain, and uniformly distributed buffer assemblies are arranged between the anchor chains close to the ship anchor. The buffer assembly comprises an outer sleeve shell and an inner buffer shell, the inner buffer shell is slidingly sleeved in the outer sleeve shell, a first spring is fixedly connected between the outer sleeve shell and the inner buffer shell, and a connecting head is welded on the outer portion of the outer sleeve shell and the inner buffer shell. The first spring is arranged between the outer sleeve shell and the inner buffer shell, and a telescopic reinforcing assembly is arranged on the outer portion of the outer sleeve shell.

Description

Technical Field

[0001] This invention relates to the field of anchoring equipment technology, and in particular to a near-shore marine anti-wind and wave anchoring device. Background Technology

[0002] Anchoring is a fundamental method for ships to moor at sea. It uses anchor chains to secure the ship to a predetermined area, preventing it from drifting under the influence of wind and waves. In complex sea conditions, such as nearshore waters, the periodic impact loads caused by wind and waves are a major challenge for anchoring systems. The ship experiences severe heaving and rolling in the waves, causing the anchor chain to withstand instantaneous peak tensile forces far exceeding those in calm water conditions. This can easily lead to anchor chain overload, breakage, or even dragging of anchor, seriously threatening the safety of the ship and its crew. Therefore, how to effectively reduce the dynamic impact loads on anchoring systems under wind and wave conditions has become a key technical issue of concern in this field.

[0003] To address the aforementioned issues, various improvement schemes have emerged in the prior art. Some existing technologies utilize the weight of counterweights in the anchor chain to provide a certain buffering effect; others employ elastic damping rings to buffer vibrations generated during anchor chain deployment and retrieval; still others combine pulleys with floating buffer components to increase the flexibility of the mooring system. These schemes optimize the stress state of the mooring system from different perspectives, improving the stress environment of the anchor chain to some extent. However, these schemes mostly focus on counterweights or local vibration reduction, and the compatibility of their buffering mechanisms with the periodic dynamic load characteristics caused by wind and waves still requires further research. Moreover, some schemes involve numerous components, posing certain engineering challenges for long-term use and maintenance in the high salt spray and high humidity environment of nearshore waters. Therefore, this application provides a nearshore marine wind and wave resistant mooring device to meet the requirements. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a near-shore marine anti-wind and wave mooring device to solve the problems of poor dynamic impact load buffering effect of existing mooring devices under wind and wave conditions, and the complex structure and poor weather resistance of some mooring devices.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A near-shore marine anti-wave mooring device includes an anchor and an anchor chain. A uniformly distributed buffer assembly is arranged between the anchor chains near the anchor. The buffer assembly includes an outer shell and an inner buffer shell, with the inner buffer shell slidably fitted inside the outer shell. A first spring is fixedly connected between the outer shell and the inner buffer shell. Connectors are welded to the exterior of both the outer shell and the inner buffer shell, and these connectors are fixedly connected to the anchor chain. The buffer assembly is used to absorb the periodic impact of wind and waves. A retractable reinforcing assembly is provided outside the outer shell. This reinforcing assembly is used to fix the relative position of the anchor chain to the seabed. The reinforcing assembly includes an assembly area on the outside of the outer shell that corresponds one-to-one with the position of a limiting block, and uniformly distributed telescopic claws fitted within the assembly area.

[0006] Optionally, one end of the outer shell is closed, and the other end has an opening that matches the shape of the inner buffer shell, with symmetrically distributed limiting blocks at the opening.

[0007] Optionally, the outer side of the inner buffer shell is provided with a guide groove that matches the shape of the limiting block, and one end of the inner buffer shell located inside the outer shell is open, while the other end is closed, with the connector located at the closed end of the outer shell and the inner buffer shell.

[0008] Optionally, the inner buffer shell is fixedly connected to one end inside the outer shell with evenly distributed sealing rings.

[0009] Optionally, a pressure-bearing seat is fixedly connected to one end of the telescopic claw located inside the outer shell and assembly area, and a bent end is provided at the end of the telescopic claw extending outside the assembly area, with the bending direction of the bent end being the same as the bending direction of the anchor claw.

[0010] Optionally, the outer shell and the assembly area have an internal movable cavity that matches the shape of the pressure seat, and the assembly area has an external through opening that matches the shape of the telescopic claw. A second spring is fixedly connected between the pressure seat and the movable cavity.

[0011] Optionally, the guide groove is internally fixedly connected with a pressure block that mates with the pressure seat.

[0012] Optionally, the pressure seat has a pressure-bearing surface at one end near the pressure block, and the pressure block has a pressure-bearing surface and a positioning end at one end near the pressure seat, with the shape of the pressure-bearing surface matching that of the pressure-bearing surface.

[0013] Optionally, the side of the limiting block facing the inside of the outer casing has a positioning surface that matches the shape of the pressing surface and the positioning end.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting a first spring between the outer shell and the inner buffer shell, and setting a retractable reinforcing component outside the outer shell, when the anchor chain tension rises sharply due to the impact of wind and waves, the buffer component converts the instantaneous pulse energy into elastic potential energy through the stretching deformation of the first spring, and releases it in a gentle manner after the surge, thus achieving effective buffering and stable energy release of the anchor chain impact load, keeping the anchor and anchor chain always within a safe elastic working range, and greatly improving the anchoring system's resistance to wind and waves.

[0015] By designing a trigger linkage structure consisting of a pressure block, a pressure seat, and a second spring, when the buffer component undergoes relative displacement due to wind and waves, the pressure block squeezes the pressure seat and drives the telescopic claw to extend from the outer shell, causing its bent end to further penetrate the seabed sediment layer. The degree of penetration adapts to the size of the wind and waves. The reinforcement component, as an auxiliary anchoring point, forms a spatial composite force system with the ship's anchor, jointly sharing the horizontal drag force and the pull-out force, significantly improving the anti-slip capability and pull-out bearing capacity of the anchoring system.

[0016] By setting a limiting block at the opening of the outer shell and opening a guide groove on the inner buffer shell, the limiting block is embedded in the guide groove to precisely limit the range of motion of the inner buffer shell. When the relative displacement reaches the maximum value, a reliable limit is formed by the cooperation of the positioning surface and the positioning end. This ensures that the buffer component does not detach under extreme working conditions and guarantees the precise control of the response stroke of the reinforcement component, thereby enhancing the operational reliability and safety of the overall structure.

[0017] By setting a sealing ring between the outer shell and the inner buffer shell to form a closed space, the internal air pressure change is used to assist in energy storage and reset when the buffer assembly is working. Together with the elastic force of the first spring, the buffer assembly can be smoothly returned to its original position. At the same time, the telescopic claw in the reinforcement assembly automatically retracts under the action of the second spring as the buffer assembly resets, avoiding the problem of extra resistance during the anchoring process that makes it difficult to pull out the anchor, and ensuring the smoothness of anchoring and anchoring operations.

[0018] By adopting the same connection method as conventional anchor chain links at the connector, the buffer assembly can be easily disassembled and replaced when it becomes structurally aged or damaged after long-term use. At the same time, the compact and reasonable structural design of the guide groove, movable cavity and through opening ensures smooth sliding and reliable cooperation of each moving part. The overall structure is simple and easy to maintain, effectively reducing the later use cost of the anchoring device. Attached Figure Description

[0028] like Figures 1 to 11As shown, an embodiment of the present invention provides a near-shore marine anti-wind and wave anchoring device, including an anchor 1 and an anchor chain 2. A uniformly distributed buffer assembly is arranged between the anchor chains 2 near the anchor 1. The buffer assembly includes an outer shell 3 and an inner buffer shell 4. The inner buffer shell 4 is slidably fitted inside the outer shell 3. A first spring 8 is fixedly connected between the outer shell 3 and the inner buffer shell 4. Connecting heads 5 are welded to the exterior of both the outer shell 3 and the inner buffer shell 4, and the connecting heads 5 are fixedly connected to the anchor chain 2. The buffer assembly is used to absorb the periodic impact of wind and waves. A retractable reinforcing assembly is provided on the exterior of the outer shell 3 to fix the relative position of the anchor chain 2 to the seabed. In actual use, after the ship arrives at the predetermined anchorage, the operator starts the anchor winch, releases the chain catcher, and allows the anchor 1 to be released from the anchor chain canister by its own weight, suspending below the water surface at a predetermined distance. After the anchor winch brake is released, the anchor chain 2 accelerates downhill, and the anchor 1 sinks rapidly to the seabed under the influence of gravity and chain length. After the anchor 1 contacts the seabed, as the ship slowly retreats or moves sideways due to the influence of wind and current, the anchor chain 2 is gradually straightened. The anchor claws on the anchor 1 cut into the mud or rocks under the action of horizontal tension. The part of the anchor chain 2 near the anchor 1 lies flat on the seabed, providing horizontal restraint. At the same time, the buffer assembly also makes contact with the seabed. Subsequently, under the action of wind and waves, the ship experiences pitching or heaving. At the moment when the tension of the anchor chain 2 rises sharply, the buffer assembly responds quickly and undergoes tensile deformation through the first spring 8, converting the instantaneous pulse energy of the surge impact into internal strain energy. After the surge peak, the buffer assembly uses its own elastic reset function to release the stored energy in a gentle manner, driving the anchor chain 2 to retract smoothly. During continuous wave cycles, the anchor chain 2 undergoes repeated stretching, energy storage, resetting, and energy release, effectively transforming the impact load on the anchor chain 2 into a relatively gentle undulating tension. This keeps the anchor 1 and anchor chain 2 within a safe elastic working range. When the waves are calm or the anchor chain 2 is slack, most of the reinforcing components retract into the outer shell 3, limiting the contact area with the seabed and preventing significant additional resistance to the mooring system. This ensures smooth anchoring and unanchoring operations. When the impact of waves causes relative displacement between the outer shell 3 and the inner buffer shell 4 in the buffer components, the reinforcing components respond synchronously and enter the working state, further penetrating the seabed sediment. At this time, the reinforcing components act as an auxiliary anchoring point, forming a spatial composite force system with the anchor 1, sharing the horizontal drag force and pull-out force, thereby significantly improving the anti-slip capability and pull-out bearing capacity of the entire mooring system.

[0029] In this embodiment, as Figures 1 to 5As shown, one end of the outer shell 3 is closed, and the other end has an opening that matches the shape of the inner buffer shell 4. Symmetrically distributed limiting blocks 11 are provided at the opening. The outer side of the inner buffer shell 4 has a guide groove 9 that matches the shape of the limiting block 11. The inner buffer shell 4 has an opening at one end inside the outer shell 3 and is closed at the other end. The connector 5 is located at the closed end of the outer shell 3 and the inner buffer shell 4. The inner buffer shell 4, located inside the outer shell 3, is fixedly connected to one end with evenly distributed sealing rings 12. The connection head 5 ensures that the connection between the buffer assembly and the anchor chain 2 is the same as the connection between the chain links in a conventional anchor chain 2. This allows for easy replacement after the buffer assembly has aged or been damaged over long-term use. The structure is simple and easy to maintain. A limiting block 11 at the opening of the outer shell 3 limits the range of motion of the inner buffer shell 4 within the outer shell 3. When the relative displacement between the outer shell 3 and the inner buffer shell 4 reaches its maximum value, the structure inside the inner buffer shell 4 will contact the limiting block 11 and be blocked, preventing the inner buffer shell 4 from detaching from the outer shell 3. The openings in the outer shell 3 and the inner buffer shell 4 ensure the first spring 8... The space is designed such that the two ends of the first spring 8 are fixedly connected to the inner walls of the outer shell 3 and the inner buffer shell 4, respectively. When the outer shell 3 and the inner buffer shell 4 are relatively displaced during operation, the elastic potential energy can be accumulated through the stretching of the first spring 8. After the wind and waves decrease, the elastic potential energy of the first spring 8 is released, causing the outer shell 3 and the inner buffer shell 4 to reset. The sealing ring 12 on the inner buffer shell 4 forms a closed space between the open end of the outer shell 3 and the inner wall of the inner buffer shell 4. When the buffer assembly is working, that is, when the outer shell 3 and the inner buffer shell 4 are relatively displaced, the space of the closed space becomes larger, so the internal air pressure decreases, which can also play a certain role in energy storage. It can work together with the elastic potential energy of the first spring 8 to drive the reset of the buffer assembly.

[0030] In this embodiment, as Figures 2 to 9As shown, the reinforcement component includes an assembly area 6 on the outside of the outer shell 3, corresponding one-to-one with the position of the limiting block 11, and telescopic claws 7 evenly distributed within the assembly area 6. One end of the telescopic claw 7 located inside the outer shell 3 and assembly area 6 is fixedly connected to a pressure seat 17, and the other end of the telescopic claw 7 extending outside the assembly area 6 is provided with a bent end 18. The bending direction of the bent end 18 is the same as the bending direction of the anchor claw of the anchor 1. The outer shell 3 and assembly area 6 have an active cavity 13 whose shape matches the pressure seat 17, and the assembly area 6 has a through opening 14 whose shape matches the telescopic claw 7. A second spring 16 is fixedly connected between the pressure seat 17 and the active cavity 13. When the buffer component is not in operation, the reinforcement component maintains its initial state. In the initial state, most of the reinforcement component is retracted into the outer shell 3 and assembly area 6, with only the bent end 18 of the telescopic claw 7 inserted into the seabed to provide initial auxiliary fixation for the anchor chain 2. The bending direction of the bent end 18 is set to... To ensure the auxiliary effect of the bent end 18 on the anchoring of the anchor 1, the insertion direction of the anchor claw of the anchor 1 on the seabed is the same as the insertion direction of the bent end 18. When the outer shell 3 and the inner buffer shell 4 in the buffer assembly undergo relative displacement, the reinforcement assembly also works synchronously, allowing the telescopic claw 7 to extend from the outer shell 3 and the assembly area 6, so that the bent end 18 is further inserted into the seabed, increasing the resistance between the two and the seabed, further improving the stability of the entire mooring system. At the same time, it can also ensure that the relative position of the outer shell 3 and the seabed is fixed, so that when the inner buffer shell 4 is under traction and undergoes relative displacement with the outer shell 3, the outer shell 3 will not follow the inner buffer shell 4 to cause the buffer assembly to fail to produce its working effect. After the wind and waves subside, the outer shell 3 and the inner buffer shell 4 are reset under the action of the first spring 8, and the telescopic claw 7 will also be reset under the action of the elastic force of the second spring 16, which facilitates the subsequent anchoring operation and prevents the resistance generated by the reinforcement assembly during the anchoring process from making it difficult to pull out the anchor 1.

[0031] In this embodiment, as Figures 3 to 11As shown, a pressing block 10 that mates with the pressure seat 17 is fixedly connected inside the guide groove 9. The pressure seat 17 has a pressure-bearing surface 19 at one end near the pressing block 10, and the pressing block 10 has a pressing surface 20 and a positioning end 21 at one end near the pressure seat 17. The pressing surface 20 matches the shape of the pressing surface 19. The limiting block 11 has a positioning surface 15 on its side facing the inside of the outer shell 3, which matches the shape of the pressing surface 20 and the positioning end 21. The pressing block 10 is used to trigger the operation of the reinforcement component. In the initial state, the outer shell... There is no relative displacement between the outer shell 3 and the inner buffer shell 4, and there is no contact between the pressing block 10 and the pressure seat 17. The telescopic claw 7 and the pressing block 10 are in the first engagement state. At this time, the pressing block 10 does not exert a squeezing effect on the telescopic claw 7 and the pressure seat 17. Only the bent end 18 of the telescopic claw 7 is inserted into the seabed. Under the action of the elastic force of the second spring 16, the position of the telescopic claw 7 is kept stable, providing initial fixation for the position of the outer shell 3 on the seabed. Once a relative displacement occurs between the outer shell 3 and the inner buffer shell 4... The telescopic claw 7 and the pressure block 10 are in a second engagement state. After the pressure block 10 and the pressure seat 17 are squeezed by the pressure surface 20 and the pressure surface 19, the pressure seat 17 decomposes the pressure force received by the pressure surface 19, resulting in a thrust towards the outside of the outer shell 3. This causes the pressure seat 17 to drive the telescopic claw 7 to slide in the movable cavity 13 and compress the second spring 16, so that the telescopic claw 7 and the bent end 18 are further inserted into the seabed, forming a reinforcement of the outer shell 3 at the seabed position. The degree of reinforcement varies with the size of the wind and waves. As the waves increase, the relative displacement between the outer shell 3 and the inner buffer shell 4 in the buffer assembly increases. At the same time, the pressure block 10 will also squeeze more telescopic claws 7 and pressure seats 17, allowing more telescopic claws 7 and bent ends 18 to insert into the seabed until the relative displacement between the outer shell 3 and the inner buffer shell 4 reaches its maximum value. At this time, the pressure surface 20 and the positioning end 21 at the end of the pressure block 10 come into contact with the positioning surface 15 on the limiting block 11, forming a limit between the outer shell 3 and the inner buffer shell 4, preventing the outer shell 3 and the inner buffer shell 4 from separating from each other.
