Description

Technical Field

[0001] The present invention relates to the technical field of offshore wind-solar power generation, and in particular to a basic mooring system and mooring method for offshore wind-solar power plants. Background Art

[0002] With the development of marine engineering technology, the pace of developing new energy has gradually moved from land to sea, and offshore photovoltaic power generation technology and offshore wind power technology have both developed rapidly. At present, offshore photovoltaic power generation and offshore wind power are mostly deployed and operated independently. In order to ensure the stable operation of wind turbines and photovoltaic platforms, it is necessary to use an anchoring system to fix wind turbines and photovoltaic platforms.

[0003] In order to fully improve power generation efficiency and save space and facility deployment costs, the wind and solar co-generation technology of building offshore photovoltaic power generation and offshore wind power projects in the same area has become a new trend. However, the existing independent mooring system has some problems in this scenario.

[0004] On the one hand, the operating environment and stress characteristics of offshore photovoltaic platforms and offshore wind power conductor frame foundations are different. The wind power conductor frame foundation mainly bears the gravity, wind load and wave load of the wind turbine, while the photovoltaic platform is relatively light, but the orientation and angle of the solar panels need to be considered. This makes their requirements for the mooring system different, and the traditional mooring method is difficult to meet the needs of both at the same time. On the other hand, when wind and waves act on the offshore wind and solar field system, the wind power conductor frame foundation and the photovoltaic platform will produce different degrees of movement, such as lateral swing, longitudinal swing, vertical swing, etc. These movements may cause the respective mooring cables to interfere with each other, affecting the stability and safety of the system. In addition, different movement modes may also cause the angle of the solar panels on the photovoltaic platform to change, thereby affecting the power generation efficiency. Summary of the invention

DETAILED DESCRIPTION

[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, not all of the embodiments. 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] like Figures 1 to 3 As shown, a foundation anchoring system for an offshore wind-solar power plant includes a plurality of cylindrical foundations 1 for supporting wind turbines 4, and the plurality of cylindrical foundations 1 are distributed in an array, and a plurality of adjacent cylindrical foundations 1 enclose a photovoltaic installation area for installing a floating photovoltaic platform 3.

[0022] The cylinder-type foundation 1 includes a suction cylinder 5 and an annular reinforcement foundation 7 fixedly arranged on the peripheral side of the suction cylinder 5. The annular reinforcement foundation 7 includes a plurality of monomers 12 evenly distributed along the circumferential direction of the suction cylinder 5. Two adjacent monomers 12 are detachably connected to form a reinforcement ring fixedly connected to the suction cylinder 5. A plurality of mooring rings 8 are fixedly arranged on the monomers 12. The mooring rings 8 are connected to the floating photovoltaic platform 3 in the photovoltaic installation area through mooring cables 2.

[0023] When deploying an offshore wind and solar power plant, first install a cylindrical foundation 1 in the target sea area according to the design requirements. The cylindrical foundation 1 is distributed in an array and can form multiple photovoltaic installation areas. For example, four adjacent cylindrical foundations 1 can enclose a photovoltaic installation area. After that, the wind turbine 4 is installed on the cylindrical foundation 4, and the floating photovoltaic platform 3 is set in the photovoltaic installation area. Finally, the floating photovoltaic platform 3 is connected to the mooring ring 8 on the cylindrical foundation 1 by using the mooring cable 2 to complete the deployment of the wind and solar power plant. In the cylindrical foundation 1, it is connected to the mooring ring 8 through a reinforcement ring, and there is no need to directly install the mooring ring 8 on the concrete-cast suction cylinder 5, which is easier to produce; the reinforcement ring is composed of a plurality of monomers 12. In the production stage, the monomer 12 and the mooring ring 8 can be prefabricated as a whole, and assembled on site during deployment, which is easier to transport.

[0024] After the deployment of the wind and solar power plant is completed, the wind turbine 4 and the floating photovoltaic platform 3 can realize wind power generation and photovoltaic power generation respectively, and the wind turbine 4 and the floating photovoltaic platform 3 are both anchored and fixed by the barrel foundation 1, realizing shared anchoring, and there is no need to set up independent anchoring structures for the wind turbine 4 and the floating photovoltaic platform 3, simplifying the deployment process and reducing the overall cost. On the other hand, the floating photovoltaic platform 3 can absorb part of the energy of the waves, so that when the waves hit the barrel foundation 1, the impact force is reduced, and the barrel foundation 1 can be protected. Moreover, the wind turbine 4 can absorb the energy of the sea breeze above the floating photovoltaic platform 3, thereby reducing the swing amplitude of the floating photovoltaic platform 3 caused by the sea breeze, ensuring that the floating photovoltaic platform 3 can generate electricity more stably and improve the overall power generation efficiency. In addition, different cylindrical foundations 1 are connected through floating photovoltaic platforms 3 and mooring cables 2, so that the load on a single cylindrical foundation 1 can be dispersed to other cylindrical foundations 1, avoiding damage or instability caused by excessive local force on the cylindrical foundation 1, and further ensuring the stability of the cylindrical foundation 1.

[0025] like Figures 5 to 9As shown, in order to improve the stability of the suction cylinder 5 and thus ensure the stability of the wind turbine 4 and the floating photovoltaic platform 3, two annular tube skirts 15 are fixedly connected to the lower surface of the reinforcement ring. The two tube skirts 15 are coaxially arranged and a distance is left between the two tube skirts 15. A plurality of partition baffles 16 evenly distributed along the circumferential direction of the suction cylinder 5 are fixedly connected between the two tube skirts 15. The tube skirts 15 and the partition baffles 16 cooperate to form a plurality of accommodating areas. After the suction cylinder 5 sinks into the seabed, a portion of the tube skirts 15 and the partition baffles 16 are also inserted into the seabed. Each accommodating area can accommodate a portion of soil. These soils are restricted and protected by the tube skirts 15 and the partition baffles 16 and are not easily washed away by seawater, thereby avoiding the loss of soil around the suction cylinder 5 and causing the stability of the suction cylinder 5 to decrease, thereby achieving the effect of strengthening the stability of the suction cylinder 5. In addition, because the soil is divided into a plurality of accommodating areas, the soil between different accommodating areas is relatively independent. Even if soil loss occurs in some accommodating areas, the soil in other accommodating areas will not be directly affected.

[0026] The connection method between the monomers 12 is as follows: at least one group of first positioning connecting plates 13 is fixedly provided at one end of the monomer 12, the number of the first positioning connecting plates 13 in one group is two, the two first positioning connecting plates 13 in the same group are arranged side by side and a receiving gap is left between them, at least one second positioning connecting plate 14 is fixedly provided at the other end of the monomer 12, and between two adjacent monomers 12, the second positioning connecting plate 14 on the previous monomer 12 is inserted into the receiving gap on the two outer monomers 12, and is connected to the two first positioning connecting plates 13 corresponding to the receiving gap. A group of first positioning connecting plates 13 and a second positioning connecting plate 14 can form a connection assembly for connecting two monomers 12. With this connection assembly, when splicing the monomers 12, it is only necessary to insert the second positioning connecting plate 14 into the receiving gap to complete the mutual positioning between the two adjacent monomers 12, which makes the operation simpler and helps to improve the construction efficiency.

[0027] The specific connection method of the first positioning connecting plate 13 and the second positioning connecting plate 14 is as follows: the first positioning connecting plate 13 and the second positioning connecting plate 14 are both provided with connecting sockets parallel to the plate surfaces. After the second positioning connecting plate 14 is inserted into the accommodation gap between the two first positioning connecting plates 13, they are connected by connecting rods that match the connecting sockets. The first positioning connecting plate 13 and the second positioning connecting plate 14 are plug-in connected by connecting rods, and can be quickly connected after the two monomers 12 are spliced ​​together. On the other hand, after all the monomers 12 are connected to form a reinforcement ring, the reinforcement ring is placed on the top of the suction cylinder 5, and then the monomers 12 are fixed to the suction cylinder 5 by welding. The assembly of the reinforcement ring and the suction cylinder 5 can be completed on site, and sufficient connection strength between the suction cylinder 5 and the reinforcement ring is ensured.

[0028] The specific arrangement of the partition baffle 16 is as follows: the partition baffle 16 passes through the two tube skirts 15, and the partition baffle 16 is used to divide a plurality of first areas between a tube skirt 15 close to the suction tube 5 and the suction tube 5, and a plurality of second areas are divided between the two tube skirts 15 by the partition baffle 16, and a plurality of third areas are divided by the partition baffle 16 on the peripheral side of a tube skirt 15 away from the suction tube 5. The first area, the second area, and the third area all constitute the above-mentioned accommodating area. The soil in the first area and the second area is more stable because there are obstructions on all sides. The side of the third area facing away from the suction tube 5 is open, so the stability of the soil in the third area is relatively weak. However, the part of the partition baffle 16 used to form the third area extends to the peripheral side of the suction tube 5. When the ocean current hits the suction tube 5, it can restrain the ocean current and avoid the formation of a large range of turbulence around the suction tube 5, thereby strengthening the protection of the suction tube 5.

[0029] In order to ensure the smooth installation of the barrel foundation 1, a main suction penetration device 9 is provided on the top of the suction barrel 5. The main suction penetration device 9 can discharge the seawater entering the suction barrel 5 during the sinking process of the suction barrel 5, so as to ensure that the suction barrel 5 can move downward smoothly. Similarly, an auxiliary suction penetration device is fixedly provided on the reinforcement ring inside the suction barrel 5, and the auxiliary suction penetration device is connected to all the second areas. The auxiliary suction penetration device is used to discharge the seawater in the first area and the second area during the descent of the suction barrel 5, so as to ensure that the barrel skirt 15 and the partition partition 16 can be smoothly inserted into the seabed. Both the main suction penetration device 9 and the auxiliary suction penetration device include a suction pipe and a suction pump, which belong to the conventional technology in this field and will not be described here.

[0030] In addition to using the annular reinforcement foundation 7 to improve the stability of the suction cylinder 5, a plurality of fins 6 evenly distributed along the circumferential direction may be fixedly provided on the peripheral side wall of the suction cylinder 5, the fins 6 extend into the first area, and the fins 6 are staggered with the partition partition 16. The fins 6 can improve the anti-overturning bearing capacity of the barrel foundation 1, thereby further strengthening the barrel foundation 1.

[0031] The specific fixing method of the mooring ring 8 is as follows: the mooring ring 8 includes a mounting column 18 that is penetrated on the monomer 12, one end of the mounting column 18 is fixedly connected to a ring body 22 for connecting the mooring cable 2, and the other end of all the mounting columns 18 located on the same annular reinforcement foundation 7 is commonly connected to a reinforcement connecting cable 31. Through the reinforcement connecting cable 31, all the mounting columns 18 can be connected as a whole under the reinforcement ring. When a mooring ring 8 and a mounting column 18 fall off due to excessive force or severe corrosion, the reinforcement connecting cable 31 can prevent the mooring ring 8 and the mounting column 18 from being completely separated from the monomer 12, thereby preventing the end of the mooring cable 2 connected to the barrel foundation 1 from completely falling off, so that the mooring cable 2 can continue to function, thereby ensuring the stability of the floating photovoltaic platform 3. On the other hand, the tension borne by the fallen mooring ring 8 and the mounting column 18 will be transmitted to all other mounting columns 18 through the reinforcement connecting cable 31, which can fully disperse the load. In order to reinforce the lifting ring body 22 , the mounting column 18 can be fixedly connected to a base 21 , and the lifting ring body 22 is fixed on the base 21 .

[0032] like Fig.10 As shown, the specific installation method of the mounting column 18 is as follows: a plurality of mounting holes for the mounting column 18 to pass through are provided on the monomer 12, a plurality of positioning tubes 17 corresponding to and communicating with the mounting holes are vertically fixedly provided on the upper surface of the monomer 12, a pressing ring 20 is fixedly sleeved on one end of the mounting column 18 located above the monomer 12, the pressing ring 20 abuts against the positioning tube 17 when the mounting column 18 passes through the mounting hole, and a first gasket 19 is provided between the pressing ring 20 and the positioning tube 17, the positioning tube 17 can reinforce the mounting column 18 and improve the tensile strength of the mounting column 18, the first gasket 19 is used to improve the sealing performance of the pressing ring 20 and the positioning tube 17, and slow down the corrosion rate of the mounting column 18. The end of the mounting column 18 located below the monomer 12 is connected to a connecting plate 25 through a fixing member 26, the connecting plate 25 is fixedly connected to a sleeve 24 sleeved on the mounting column 18, the sleeve 24 abuts against the lower surface of the monomer 12, and a second gasket 23 is provided between the sleeve 24 and the monomer 12. The connection plate 25, the collar 24 and the second gasket 23 cooperate to seal the end of the mounting column 18 below the monomer 12, thereby reducing the corrosion rate of the mounting column 18. The mounting column 18 is fixed in this way, and the gap between it and the monomer 12 is fully sealed, which can greatly reduce the corrosion rate of the mounting column 18. In addition, when the mooring ring 8 falls off due to damage to the mounting column 18, the connection plate 25 can be separated from the mounting column 18, and then the damaged mounting column 18 can be removed, so that it is easy to replace a new mounting column 18 and the mooring ring 8.

[0033] The specific connection method of the reinforcement connection cable 31 and the installation column 18 is as follows: the connection plate 25 is fixedly connected to two mutually parallel support rods 27, each of which is provided with a through hole 28, and the reinforcement connection cable 31 passes through the two through holes 28 in sequence. In order to further improve the connection strength between the reinforcement connection cable 31 and the installation column 18, a limit plate 29 is fixedly connected between the ends of the two support rods 27 away from the connection plate 25, and a limit top block 30 is fixedly arranged on the limit plate 29, the limit top block 30 faces the connection plate 25, and the limit top block 30 lifts the part of the reinforcement connection cable 31 located between the two through holes 28 to form a deformation portion 32. By using the limiting top block 30 to lift the reinforced connecting cable 31 to form a deformation portion 32, the reinforced connecting cable 31 can be pressed against the inner wall of the through hole 28, thereby increasing the friction between the reinforced connecting cable 31 and the support rod 27, thereby increasing the stability of the reinforced connecting cable 31, preventing the reinforced connecting cable 31 from shaking randomly, and ensuring that the reinforced connecting cable 31 can smoothly transmit the tension and achieve the effect of dispersing the load.

[0034] like Figure 4 As shown, in order to facilitate the connection of the floating photovoltaic platform 3 with the barrel foundation 1 through the mooring cable 2, when applying the present invention, the floating photovoltaic platform 3 includes a floating structure composed of a plurality of buoys 10, the floating structure is connected to at least one mooring rack 11, and the mooring cable 2 is suspended on the mooring rack 11 through a shackle.

[0035] The present invention further provides a basic anchoring method for an offshore wind-solar power plant. Based on the above-mentioned basic anchoring system for an offshore wind-solar power plant, the method includes S1 to S3.

[0036] S1. Divide the offshore wind power plant into multiple installation areas, with at least one intersection point between two adjacent installation areas. The installation areas are used to install the floating photovoltaic platform 3, and the specific shape and distribution of the installation areas can be determined according to the actual structure of the floating photovoltaic platform 3.

[0037] S2. Deploy the floating photovoltaic platform 3 in the installation area and install the barrel foundation 1 at the intersection.

[0038] S3. Use the mooring rope 2 to connect the floating photovoltaic platform 3 to the barrel foundation 1. Because two adjacent installation areas have at least one intersection point, installing the barrel foundation 1 at the intersection point can ensure that the barrel foundation 1 can be connected to at least one floating photovoltaic platform 3, ensuring that the wind turbine 4 and the floating photovoltaic platform 3 can be moored together.

[0039] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0040] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
