Description
Technical Field
[0001] The utility model relates to the technical field of ocean engineering, and particularly relates to a mooring system and an anti-winding component thereof. Background Art
[0002] In ocean engineering, mooring systems are widely used to fix facilities such as offshore platforms, buoys, and aquaculture cages to ensure that these structures maintain stable positioning and balance under the action of wind, waves, and currents. A typical mooring system consists of an anchor chain, a mooring cable, and an anchor. The anchor is arranged on the seabed to provide a firm fixing point, while the anchor chain and the mooring cable connect the anchor to the floating body.
[0003] However, in the semi-submersible operation mode, the mooring system and the aquaculture cage move together with the change of the ocean environment. This dynamic interaction may cause the mooring cable to wind around the buoy at the bottom of the cage, interfering with the normal function of the mooring system. This winding phenomenon not only hinders the stable function of the mooring system but also may damage the balance of the cage. Once the cage loses stability and tilts, it may cause fish to escape, resulting in serious economic losses.
[0004] Therefore, in view of this problem, there is an urgent need to develop a new solution to prevent the winding phenomenon and improve the stability of the cage. Summary of the Utility Model
[0005] The main purpose of the utility model is to propose a mooring system and an anti-winding component thereof, aiming to improve the stability of the aquaculture cage.
[0006] To achieve the above purpose, the anti-winding component proposed by the utility model includes a floating member and a connecting structure. The connecting structure has a first end and a second end. The first end of the connecting structure is connected to the floating member, and the second end of the connecting structure is used to connect the mooring cable of the aquaculture cage. The floating member is used to float or suspend in the water body to drive the mooring cable to rise, so that the mooring cable is away from the buoy at the bottom of the aquaculture cage.
[0007] In one embodiment, the connecting structure further has a third end, and the third end of the connecting structure is used to connect one end of the anchor chain, and the other end of the anchor chain is used to connect to the seabed.
[0008] In one embodiment, the connecting structure includes a plate body, a first connecting member, a second connecting member, and a third connecting member. One end of the first connecting member, one end of the second connecting member, and one end of the third connecting member are connected to the vertex or edge of the plate body. The other end of the first connecting member is connected to the floating member, the other end of the second connecting member is connected to the mooring cable, and the other end of the third connecting member is connected to the anchor chain.
[0009] In one embodiment, the plate body is triangular, the plate body includes a first vertex, a second vertex and a third vertex, one end of the first vertex is connected to one end of the first connecting member, one end of the second vertex is connected to one end of the second connecting member, and one end of the third vertex is connected to one end of the third connecting member.
[0010] In one embodiment, the first connecting member, the second connecting member and the third connecting member are connecting shackles.
[0011] In one embodiment, the plate body is an equilateral triangle.
[0012] In one embodiment, the minimum breaking load of the plate body is greater than the breaking load of the mooring cable and the minimum breaking load of the anchor chain.
[0013] The present utility model also provides a mooring system, which includes the anti-tangling component in any of the above embodiments.
[0014] In one embodiment, the mooring system includes a mooring cable and an anchor eye plate; the anchor eye plate is connected to the first connection point of the mooring cable; the second end of the connection structure is connected to the second connection point of the mooring cable, and the second connection point is spaced from the first connection point; the anchor eye plate is used to be fixed at the bottom of the aquaculture cage.
[0015] In one embodiment, the mooring system further includes an anchor chain and a fixed anchor; one end of the anchor chain is connected to the connection structure, and the other end of the anchor chain is provided with an enlarged link and a terminal shackle; the fixed anchor is provided with an anchor shackle, the terminal shackle is connected to the enlarged link and connected to the anchor shackle; the fixed anchor is used to be fixed on the seabed.
[0016] The technical solution of the present utility model sets the anti - entanglement component to include a floating member and a connection structure; wherein, the connection structure has a first end and a second end, the first end of the connection structure is connected to the floating member, and the second end of the connection structure is used to connect the mooring cable of the aquaculture cage; the floating member is used to float or suspend in the water body to drive the mooring cable to rise, so that the mooring cable is far away from the buoy at the bottom of the aquaculture cage. With such a setting, when the mooring system is applied to an aquaculture cage in a semi - submersible operation mode, the floating member provides a certain upward pulling force for the mooring cable, lifting the mooring cable to a certain height, thereby increasing the vertical angle between the mooring cable and the bottom of the aquaculture cage. This lifting effect keeps the mooring cable away from the buoy at the bottom of the cage, effectively avoiding the entanglement of the mooring cable with the buoy and other bottom structures, and preventing the cage from losing balance. In addition, when the mooring system is applied to an aquaculture cage in a bottom - sitting operation mode, the pulling force provided by the floating member lifts the mooring cable above the seabed surface. This measure prevents the friction between the mooring cable and the seabed surface and the attachment of seabed organisms, thereby reducing the damage of the mooring cable, extending its service life, and further enhancing the overall stability of the cage.

[0029] A typical mooring system consists of an anchor chain, a mooring cable and an anchor. The anchor is arranged on the seabed to provide a firm fixing point, and the anchor chain and the mooring cable connect the anchor to the floating body.
[0030] However, in the semi-submersible operation mode, the mooring system and the aquaculture cage move together with the changes in the marine environment. This dynamic interaction may cause the mooring cables to entangle with the buoys at the bottom of the cage, interfering with the normal function of the mooring system. This entanglement phenomenon not only hinders the stable function of the mooring system but also may disrupt the balance of the cage. Once the cage loses stability and tilts, it may lead to the escape of fish, resulting in serious economic losses.
[0031] Therefore, to address this issue, a new solution needs to be developed to prevent the entanglement phenomenon and improve the stability of the cage. The present utility model proposes an anti-entanglement component.
[0032] Please refer to Figure 1 and Figure 3 , in an embodiment of the present utility model, the anti-entanglement component includes a floating member 1 and a connecting structure 2; wherein, the connecting structure 2 has a first end and a second end, the first end of the connecting structure 2 is connected to the floating member 1, and the second end of the connecting structure 2 is used to connect the mooring cable 3 of the aquaculture cage; the floating member 1 is used to float or suspend in the water body to drive the mooring cable 3 to rise, so that the mooring cable 3 is away from the buoy at the bottom of the aquaculture cage. Among them, the floating member 1 can be an object such as a buoy, a floating body, or a float that can suspend in the water body. With such a setting, when the anti-entanglement component is applied to the aquaculture cage in the semi-submersible operation mode, the floating member 1 provides a certain upward pulling force for the mooring cable 3 to lift the mooring cable 3 by a certain height, and then the vertical angle a between the mooring cable 3 and the bottom of the cage can be increased. Specifically, one side of the vertical angle a is the vertical straight line where the connection point of the mooring cable 3 and the bottom of the cage is located, and the other side of the vertical angle a is the straight line where the mooring cable 3 is located; when the mooring cable 3 is lifted by a certain height, the degree of upward inclination of the straight line where the mooring cable 3 is located increases, and thus the vertical angle a increases. Correspondingly, as the vertical angle a increases, the mooring cable 3 gets farther and farther away from the buoy at the bottom of the aquaculture cage, so as to avoid the entanglement of the mooring cable 3 with the structures at the bottom of the cage such as the buoy and disrupt the balance of the cage, and the stability of the cage can be improved.
[0033] In addition, refer to Figure 2, when applying the mooring system to the aquaculture cage in the bottom-sitting operation mode, the mooring cable 3 sinks to the seabed with the cage and is arranged lying on the seabed. Under the disturbance of ocean currents, the mooring cable 3 will rub against the seabed sand and cause wear; and the long-term lying-on-the-bottom arrangement is also likely to cause marine organisms to attach to the surface of the mooring cable 3, thereby damaging the strength of the mooring cable 3 and affecting the service life of the mooring cable 3. When the mooring cable 3 breaks or is damaged, it will also cause the cage to lose stability, thereby causing economic losses to aquaculture. When applying the anti-twisting component of the present utility model to the aquaculture cage in the bottom-sitting operation mode, the pulling force provided by the floating member 1 raises the mooring cable 3 above the seabed surface, preventing damage caused by the friction between the mooring cable 3 and the seabed surface and the attachment of seabed organisms, and extending the service life of the mooring cable 3, thereby further enhancing the stability of the cage.
[0034] In some embodiments, referring to FIGS. 1 and Figure 3 , the connecting structure 2 further has a third end. The third end of the connecting structure 2 is used to connect one end of the anchor chain 4, and the other end of the anchor chain 4 is used to connect to the seabed. On the one hand, since the mooring cable and the anchor chain 4 are inherently required to be connected together in the related prior art, with such a setting, it is equivalent to setting the connecting structure 2 at the connection between the anchor chain 4 and the mooring cable 3, and it is not necessary to separately set a connection at other parts of the mooring cable 3, which is beneficial to convenient production and simplification of the production steps. On the other hand, with such a setting, it is equivalent to setting the connecting structure 2 at the end of the mooring cable 3 and connecting the floating member 1, so that the entire mooring cable 3 for mooring can rise, and the vertical angle a can be increased as much as possible, and the contact between the mooring cable 3 and the seabed during bottom-sitting can be reduced as much as possible. Specifically, when the rising height of the floating member 1 is the same, the greater the horizontal distance between the floating member 1 and the cage, the greater the corresponding vertical angle a, and the better the anti-twisting effect.
[0035] Furthermore, in some embodiments, referring to Figure 3 , the connecting structure 2 includes a plate body 21, a first connecting member 22, a second connecting member 23, and a third connecting member 24; one end of the first connecting member 22, one end of the second connecting member 23, and one end of the third connecting member 24 are connected to the vertex or edge of the plate body 21, the other end of the first connecting member 22 is connected to the floating member 1, the other end of the second connecting member 23 is connected to the mooring cable 3, and the other end of the third connecting member 24 is connected to the anchor chain 4. The plate body 21 can increase the area for connection and improve the connection stability; and the setting of the plate body 21 and the first connecting member 22, the second connecting member 23, and the third connecting member 24 can make the connection between the floating member 1, the mooring cable 3, and the anchor chain 4 more convenient.
[0036] Furthermore, in one embodiment, referring to Figure 3, the plate body 21 is arranged in a triangular shape. The plate body 21 includes a first vertex 211, a second vertex 212, and a third vertex 213. One end of the first connecting member 22 is connected to the first vertex 211, one end of the second connecting member 23 is connected to the second vertex 212, and one end of the third connecting member 24 is connected to the third vertex 213. With such an arrangement, the floating member 1, the mooring cable 3, and the anchor chain 4 can be spaced apart at the connection points, so as to balance the force and avoid the connection points from being easily broken due to excessive force concentration.
[0037] In one embodiment, referring to Figure 3 , the plate body 21 is arranged in an equilateral triangle shape to make the force disperse more evenly. It can be understood that when the first connecting member 22, the second connecting member 23, and the third connecting member 24 are respectively connected to the middle positions of the three sides of the equilateral triangle, it can also achieve the effect of further evenly dispersing the force.
[0038] In one embodiment, referring to Figure 3 , the first connecting member 22, the second connecting member 23, and the third connecting member 24 are connecting shackles. A connecting shackle is a tool commonly used for connection and fixation, which can facilitate installation and disassembly. In addition, since the buckle part of the connecting shackle has a relatively large inner diameter, it can provide a space for angular deflection between the floating member 1 and the plate body 21, between the mooring cable 3 and the plate body 21, and between the anchor chain 4 and the plate body 21, so that they can deflect with the change of the water body to buffer the water flow impact caused by the change of the water body.
[0039] In some embodiments, the minimum breaking load of the plate body 21 is greater than the breaking load of the mooring cable 3 and the minimum breaking load of the anchor chain 4 to reduce the risk of the plate body 21 breaking when the mooring cable 3 and the anchor chain 4 are working normally.
[0040] The present utility model also provides a mooring system, which includes the anti - entanglement component in the above - mentioned embodiment. The specific structure of the anti - entanglement component refers to the above - mentioned embodiment. Since this mooring system adopts all the technical solutions of the above - mentioned all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above - mentioned embodiments, and will not be elaborated here one by one. Among them, referring to Figure 1 、 Figure 3 and Figure 4 , the mooring system includes a mooring cable 3 and an anchor eye plate 6; the anchor eye plate 6 is connected to the first connection point of the mooring cable 3; the second end of the connection structure 2 is connected to the second connection point of the mooring cable 3, and the second connection point is spaced from the first connection point; the anchor eye plate 6 is used to be fixed at the bottom of the aquaculture cage. The first connection point and the second connection point are spaced apart, so that the floating member 1 can change the angle between the part of the mooring cable 3 from the first connection point to the second connection point and the vertical direction, so as to keep the mooring cable 3 away from the structures such as the floating drum at the bottom of the aquaculture cage and avoid entanglement, which affects the stability of the cage.
[0041] In some embodiments, referring to Figure 1 , Figure 3 and Figure 5 , the mooring system further includes an anchor chain 4 and a fixed anchor 5; one end of the anchor chain 4 is connected to the connection structure 2, and a enlarged link 41 and a terminal shackle 42 are provided at the other end of the anchor chain 4; the fixed anchor 5 is provided with an anchor shackle 51, and the terminal shackle 42 is connected to the enlarged link 41 and connected to the anchor shackle 51; the fixed anchor 5 is used to be fixed on the seabed. Specifically, by providing the enlarged link 41 at the other end of the anchor chain 4, the inner diameter of the end of the anchor chain is enlarged, so that the end of the anchor chain 4 can be better connected to other structures. The terminal shackle 42 and the anchor shackle 51 are structures that facilitate disassembly and installation. By connecting the enlarged link 41 and the terminal shackle 42, the anchor shackle 51 and the fixed anchor 5, and then connecting the terminal shackle 42 and the anchor shackle 51, it is beneficial to reduce the assembly difficulty. Moreover, since the body part of the shackle has a relatively large inner diameter, the structures connected to each other can deflect, which is beneficial to buffering the water flow impact caused by the change of the water body.
[0042] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
