[0002] A mooring system is a system that connects a surface structure to a fixed point through a mechanical device. It enables the moored structure to withstand certain environmental conditions and ensures the safety of the structure and the mooring system itself when encountering extreme water surface conditions.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In order to solve the problem of high cost of mooring systems in the prior art, the present invention provides a mooring component and a mooring system, wherein the mooring system includes the mooring component.

[0022] like Figure 1 As shown, the mooring assembly includes a buoy 10, a counterweight 20 and an adjusting member 30. The buoy 10 floats on the water surface or in the water. The counterweight 20 is set in the water, and the self-weight of the counterweight 20 is greater than the buoyancy. The upper and lower ends of the adjusting member 30 are respectively connected to the buoy 10 and the counterweight 20, and the left and right ends of the adjusting member 30 are respectively used to connect with the first mooring cable 50 and the second mooring cable 60, and the buoyancy of the buoy 10 is greater than the self-weight of the buoy 10 and the adjusting member 30. The adjusting member 30 is deformably arranged to adjust the distance between the buoy 10 and the counterweight 20 under the drive of the first mooring cable 50 and the second mooring cable 60.

[0023] By setting a mooring assembly including a buoy 10, a counterweight 20 and an adjusting member 30, the buoy 10 floats on the water surface or in the water, the counterweight 20 is set in the water, and the self-weight of the counterweight 20 is greater than the buoyancy, the upper and lower ends of the adjusting member 30 are respectively connected to the buoy 10 and the counterweight 20, the left and right ends of the adjusting member 30 are respectively used to connect with the first mooring cable 50 and the second mooring cable 60, and the buoyancy of the buoy 10 is greater than the self-weight of the buoy 10 and the adjusting member 30, and the adjusting member 30 is deformably arranged, The distance between the buoy 10 and the counterweight 20 is adjusted under the drive of the first mooring cable 50 and the second mooring cable 60. In this way, when the mooring cable is subjected to tension, the buoy 10 is pulled downward and the counterweight 20 is pulled upward under the drive of the deformation of the adjusting member 30. The distance between the buoy 10 and the counterweight 20 is shortened, and the distance between the two mooring cables is increased, which is equivalent to the elongation of the mooring accessories, thereby effectively reducing the peak load of the mooring cable, reducing the use requirements of the mooring cable, and thereby reducing the cost of the mooring system.

[0024] It is understandable that the design of the buoy 10 needs to ensure that its buoyancy is greater than the sum of its own weight and the weight of the adjusting member 30, ensuring that the buoy 10 can float on the water surface or a certain depth underwater without sinking to the bottom when it is underwater. Further, there are multiple options for the shape of the buoy 10, such as cylindrical and spherical, and such a design can be optimized based on specific marine environmental conditions and the needs of the mooring system to achieve optimal buoyancy performance and stability. By adopting a cylindrical or spherical buoy 10 design, not only can the buoyancy performance of the mooring system be improved, but also good stability can be maintained under different sea conditions. For example, in seas with strong winds and waves, the spherical buoy can more effectively reduce water flow resistance and reduce the additional load caused by wave impact due to its streamlined shape; while in relatively calm seas, the cylindrical buoy can provide sufficient buoyancy support while maintaining stability due to its larger lateral area. This flexible design enables mooring accessories to be widely used in various offshore wind power and photovoltaic projects, especially in deep sea areas, where its stability and adaptability are more prominent.

[0025] Furthermore, the gravity of the counterweight 20 is designed to be greater than its buoyancy in water, ensuring that it can stably maintain a certain position underwater and will not drift with the water flow. The shape of the counterweight 20 can be a cube or a cylinder. The specific shape to be selected depends on the overall layout of the mooring system and the seabed topography. The shape configuration of the counterweight 20, whether it is a cube or a cylinder, is to ensure that the mooring accessories remain stable underwater and will not be affected by the ocean fluid dynamics and cause uncontrollable displacement. In a deep-sea environment, the cubic counterweight can better resist the influence of seabed slopes or uneven terrain due to its tetrahedral stability and maintain the verticality of the mooring system; while the cylindrical counterweight is suitable for flat areas on the seabed, and its smooth surface can reduce friction with the seabed and reduce additional resistance. Through the above design, the mooring accessories can maintain the stability of the system in a changing marine environment, whether in deep sea or shallow sea, and provide reliable support for offshore wind power and photovoltaic platforms.

[0026] like Figure 1 As shown, the adjusting member 30 includes a first connecting plate 31 and a second connecting plate 32, which are arranged at intervals on the left and right and are respectively connected to the first mooring cable 50 and the second mooring cable 60. In other words, the first mooring cable 50 and the second mooring cable 60 are connected to the first connecting plate 31 and the second connecting plate 32 to achieve tensioning of the adjusting member 30, thereby driving the adjusting member 30 to deform to reduce the distance between the buoy 10 and the counterweight 20, and at the same time lengthening the distance between the first mooring cable 50 and the second mooring cable 60 to reduce the peak load of the mooring cable.

[0027] like Figure 1 As shown, the adjusting member 30 further includes two first connecting cables 33 , one end of each of the two first connecting cables 33 is connected to the bottom of the buoy 10 , and the other end is connected to the first connecting plate 31 and the second connecting plate 32 respectively.

[0028] like Figure 1 As shown, the adjusting member 30 also includes two second connecting cables 34 , one end of each of the two second connecting cables 34 is connected to the top of the counterweight 20 , and the other end is connected to the first connecting plate 31 and the second connecting plate 32 , respectively.

[0029] like Figure 1 As shown, a lifting lug 40 is provided at the bottom of the buoy 10 and the top of the counterweight 20 , one end of each of the two first connecting cables 33 is connected to the lifting lug 40 , and one end of each of the two second connecting cables 34 is connected to the lifting lug 40 .

[0030] In this embodiment, two first connecting cables 33 and two second connecting cables 34 are arranged correspondingly up and down and connected end to end to form a quadrilateral, the upper and lower ends of the quadrilateral are respectively connected to the buoy 10 and the counterweight 20, and the left and right ends of the quadrilateral are respectively used to connect to the first mooring cable 50 and the second mooring cable 60. Specifically, when the mooring attachment is installed on the mooring cable, the buoyancy of the buoy 10 is greater than the gravity and floats upward, and the buoyancy of the counterweight 20 is less than the gravity and pulls downward, and the four connecting cables between the buoy 10 and the counterweight 20 are in a rhombus shape.

[0031] In this embodiment, the first connecting plate 31 is a three-eye plate, and the corresponding second connecting plate 32 is also a three-eye plate.

[0032] Furthermore, the first connecting cable 33 and the second connecting cable 34 in this embodiment are chain structures at least at the ends, so that they are locked with the holes on the three-eye plate and the lifting ears 40, so that the connection between the connecting cable and the connecting plate, the buoy 10 and the counterweight 20 is more flexible, which facilitates the adjustment member 30 to follow the deformation of the mooring cable.

[0033] In this embodiment, the material selection of the three-eye plate includes stainless steel, aluminum alloy and composite materials. Different material selections will affect the corrosion resistance, strength and weight of the three-eye plate, and thus affect the performance of the entire mooring accessory. The design of the three-eye plate must ensure that it has sufficient strength to withstand the tension of the connecting cable and can be safely and stably connected to the mooring cable. Among them, the stainless steel three-eye plate is suitable for environments with strong seawater corrosion due to its excellent corrosion resistance and high strength, ensuring stability and reliability in long-term use; the aluminum alloy three-eye plate is suitable for mooring systems that need to reduce the overall weight due to its light weight and good processing performance, improving the efficiency of installation and maintenance; the composite material three-eye plate performs well in corrosion resistance and lightweight, making it an ideal choice for application in deep sea and high salinity waters. Through precise material and design selection, the three-eye plate can optimize the performance of the entire mooring accessory and meet the application requirements under specific sea conditions.

[0034] like Figure 1 As shown, the present application also provides a mooring system, comprising the above-mentioned mooring assembly.

[0035] like Figure 1 As shown, the mooring system further includes a first mooring cable 50 and a second mooring cable 60 , and the first mooring cable 50 and the second mooring cable 60 are respectively connected to the left and right ends of the adjusting member 30 .

[0036] In this embodiment, the material selection of the mooring cable includes steel wire rope, polyester fiber, nylon and polypropylene. The selection of these materials needs to take into account the strength, corrosion resistance and cost of the cable, as well as the environmental conditions of the specific sea area. When the mooring accessories are installed on the mooring cable, the force of the buoy 10 and the counterweight 20 is transmitted to the mooring cable through the three-eye plate to achieve load adjustment of the mooring system. Among them, the steel wire rope is suitable for mooring systems that need to withstand large tension due to its high strength and wear resistance, especially in deep sea or harsh sea conditions; polyester fiber and nylon cables are suitable for shallow seas and seas with small wind and waves due to their good flexibility and low cost, which can effectively reduce the overall cost of the system; and polypropylene cables have obvious advantages in offshore installation and maintenance due to their light weight and easy handling. By combining the configuration of the buoy, counterweight and forked connecting cable, and reasonably selecting the material of the mooring cable, the mooring accessories can effectively adapt to different sea conditions and provide reliable and economical mooring solutions for offshore wind power and photovoltaic facilities.

[0037] When the mooring attachment is installed on the mooring cable and is not affected by external forces, the buoy 10 is in a floating state because its buoyancy is greater than its gravity, and the counterweight 20 is in a pulled-down state because its gravity is greater than its buoyancy, and the four connecting cables between the two naturally form a diamond structure. In this state, the buffering effect of the mooring attachment is the best, and it can effectively absorb and disperse the impact load imposed by the external environment on the mooring cable.

[0038] When the mooring cable is subjected to tension, such as wind and wave impact or ocean current, the buoy 10 and the counterweight 20 will be pulled downward and upward respectively, so that the distance between them is shortened, and the distance between the two three-eye plates is increased, which is equivalent to the overall lengthening of the mooring accessories. This dynamic adjustment mechanism can effectively reduce the peak load of the mooring cable and reduce the fatigue of the cable, thereby extending the service life of the mooring system and reducing maintenance costs, which is of great significance for the stable operation of offshore wind power and photovoltaic systems in deep seas.

[0039] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: by setting a mooring assembly including a buoy 10, a counterweight 20 and an adjusting member 30, the buoy 10 floats on the water surface or in the water, the counterweight 20 is set in the water, and the self-gravity of the counterweight 20 is greater than the buoyancy, the upper and lower ends of the adjusting member 30 are respectively connected to the buoy 10 and the counterweight 20, the left and right ends of the adjusting member 30 are respectively used to connect with the first mooring cable 50 and the second mooring cable 60, and the buoyancy of the buoy 10 is greater than the self-gravity of the buoy 10 and the adjusting member 30. The adjusting member 30 is deformably arranged to adjust the distance between the buoy 10 and the counterweight 20 under the drive of the first mooring cable 50 and the second mooring cable 60. When the mooring cable is subjected to tension, the buoy 10 is pulled downward and the counterweight 20 is pulled upward under the deformation of the adjusting member 30. The distance between the buoy 10 and the counterweight 20 is shortened and the distance between the two mooring cables is increased, which is equivalent to the elongation of the mooring accessories, thereby effectively reducing the peak load of the mooring cable, reducing the use requirements of the mooring cable, and further reducing the cost of the mooring system.
