[0002] With the transformation of my country's energy structure, wind energy has shown enormous potential, and offshore wind power has become a key project in the development of renewable energy. Fisheries, as an important marine resource, also have significant development value in distant-water fisheries, and the emergence of marine ranches has effectively improved the efficiency of marine fishery resource development. The integrated development of offshore wind power and marine ranching can share marine resources, collaborate on design, construction, and operation and maintenance, and improve the overall benefits of comprehensive development, thus attracting increasing attention.
[0003] Currently, offshore wind-fishery integrated power plants mainly use floating foundations and some jacket foundations. Examples of combining monopile foundation wind turbines with marine ranches are rare, and the main methods are either setting up floating net cages or fixing aquaculture valve boxes to the wind turbine tower. These methods of combining marine ranches with offshore wind power have poor stability, cannot avoid the disturbance of the nets by ocean currents, and have limited aquaculture space. Furthermore, fixed monopile wind turbine foundations have poor resistance to lateral loads in extreme environments.

Detailed Implementation
[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0046] The purpose of this invention is to provide a wind-fish integrated aquaculture device and its installation method for extending the service life and preventing collisions of offshore wind turbines, in order to solve the problems existing in the prior art. By setting up multiple fixed piles, the burden on the single pile of the wind turbine foundation can be reduced, and its service life can be extended. In addition, the fixed piles can also protect the single pile of the wind turbine foundation and prevent it from being collided with by marine objects.
[0047] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0048] Example 1
[0049] like Figures 1-5As shown, this embodiment provides a wind-fish integrated aquaculture device for extending the lifespan and preventing collisions of offshore wind turbines. It includes a wind turbine foundation monopile 1, the upper end of which is used to install wind power generation equipment. The wind power generation equipment is existing technology, so its specific structure will not be described in detail here. Multiple fixed piles 2 are provided around the wind turbine foundation monopile 1. Each fixed pile 2 is connected to the wind turbine foundation monopile 1 via a support rod 7, thus connecting the wind turbine foundation monopile 1 and the fixed piles 2 into a single unit. An aquaculture platform deck 3 is provided between the wind turbine foundation monopile 1 and each fixed pile 2, as well as between two adjacent fixed piles 2. A corresponding support rod 7 is provided on the lower surface of the aquaculture platform deck 3 between the wind turbine foundation monopile 1 and the fixed piles 2. A vertical telescopic mesh clamp 5 is provided on the lower surface of the aquaculture platform deck 3 between two adjacent fixed piles 2. A counterweight ring 8 is fitted on the outer side of the wind turbine foundation monopile 1. The inner diameter of the counterweight ring 8 is larger than the outer diameter of the wind turbine foundation monopile 1, so the counterweight ring 8 does not directly contact the wind turbine foundation monopile 1. The counterweight ring 8 is located below the aquaculture platform deck 3. Specifically, in actual use, the counterweight ring 8 is located on the seabed. A telescopic mesh 4 is provided between each vertical telescopic mesh clamp 5 and the counterweight ring 8. The vertical telescopic mesh clamp 5 and the counterweight ring 8 are respectively connected to the upper and lower ends of the telescopic mesh 4. A horizontal telescopic mesh clamp 6 is connected to the left and right sides of each telescopic mesh 4. The upper end of the horizontal telescopic mesh clamp 6 is fixed to a corresponding fixed pile 2, and the lower end of the horizontal telescopic mesh clamp 6 is fixed to the counterweight ring 8.
[0050] In practical use, multiple fixed piles 2 can effectively share some of the load on the wind turbine foundation monopile 1, thereby extending its service life. They can also help the wind turbine foundation monopile 1 resist some ocean currents, thus improving its stability. Furthermore, the fixed piles 2 can prevent the wind turbine foundation monopile 1 from being struck by marine objects. The telescopic netting 4, due to its elasticity, can extend when facing strong ocean currents, thereby mitigating the impact of the currents and extending its service life.
[0051] In this embodiment, a platform handrail 10 is installed on the aquaculture platform deck 3 to ensure the safety of the staff. The handrail is made of aluminum alloy and its height is generally 1000mm-1200mm, preferably 1200mm.
[0052] In this embodiment, an equipment room 9 is provided on one of the fixed piles 2, and a ladder is also provided. The lower end of the ladder is located on the deck 3 of the aquaculture platform, and the upper end of the ladder is located at the bottom of the equipment room 9, allowing workers to enter via the bottom ladder. The equipment room 9 can accommodate the placement of relevant equipment, such as monitoring equipment and fishing equipment. The diameter of the equipment room 9 is 5000mm-8000mm, preferably 8000mm, and the height is 3000mm-4000mm, preferably 4000mm. The equipment room 9 is constructed using a prefabricated building method, processed in a coastal factory, and directly assembled on the fixed piles 2.
[0053] In this embodiment, there are six fixed stakes 2, six telescopic nets 4, six vertical telescopic net clips 5, and six horizontal telescopic net clips 6. From a top view, the six vertical telescopic net clips 5 can form a regular hexagon, with the six fixed stakes 2 located at its six vertices. The telescopic nets 4 are made of ultra-high molecular weight polyethylene fiber. Each telescopic net 4 has a vertical telescopic net clip 5 connected to its upper end, a horizontal telescopic net clip 6 on each side, and a counterweight ring 8 connected to its lower end. The six telescopic nets 4 together form an aquaculture cage.
[0054] In this embodiment, as Figure 4 As shown, the vertical telescopic net clamp 5 includes a vertical net clamp shell, which is a cylindrical shell. A vertical expansion joint is provided on the vertical net clamp shell. A vertical telescopic shaft is rotatably connected inside the vertical net clamp shell. One end (upper end) of the telescopic net 4 is wound around the vertical telescopic shaft. The vertical telescopic shaft is connected to the inner wall of the vertical net clamp shell via a vertical return torsion spring. One end of the vertical return torsion spring is connected to the vertical telescopic shaft, and the other end is connected to the inner wall of the vertical net clamp shell. When there is a large ocean current, the current will push the telescopic net 4 to extend, and the telescopic net 4 inside the vertical net clamp shell will continuously extend, storing energy in the vertical return torsion spring. When the ocean current recedes and there is no large external force, under the action of the elastic potential energy of the vertical return torsion spring, the vertical telescopic net clamp 5 will retract part of the telescopic net 4.
[0055] like Figure 5As shown, the transverse telescopic mesh clip 6 includes a transverse mesh clip shell, with a transverse telescopic slit on each side of the shell. A transverse telescopic shaft is rotatably connected inside the shell. The adjacent ends of the telescopic mesh 4 on both sides of the transverse telescopic mesh clip 6 are wound together on this shaft. When the shaft rotates, the telescopic mesh 4 on both sides can simultaneously extend or retract. The shaft is connected to the inner wall of the shell via a transverse return torsion spring. When there is a strong ocean current, it pushes the telescopic mesh 4 to extend, causing the two telescopic mesh 4 inside the shell to continuously extend, storing energy in the return torsion spring. When the current recedes and there is no significant external force, the transverse telescopic mesh clip 6 retracts some of the telescopic mesh 4 on both sides under the elastic potential energy of the return torsion spring.
[0056] Both the vertical and horizontal mesh enclosures are made of steel, resulting in a robust structure and low manufacturing cost.
[0057] In this embodiment, both ends of the support rod 7 are connected to the wind turbine foundation monopile 1 and the fixed pile 2 via flanges, respectively. Flange connections facilitate installation and replacement, and offer a longer service life compared to welding or other methods. This integrates the wind turbine foundation monopile 1 and the aquaculture cage into a unified system. The support rod 7 transmits force between the monopile 1 and the fixed pile 2, enabling them to share environmental loads, increasing the stability of the monopile 1, and extending its service life. The dimensions and materials of the wind turbine foundation monopile 1 are determined by the actual project, taking into account the overall "wind-fishery integration" structural system during the design phase.
[0058] In this embodiment, both the single pile 1 and the fixed pile 2 of the wind turbine foundation are steel pipes, and their specific dimensions are as follows:
[0059] The outer diameter of the wind turbine foundation monopile 1 is 8000mm, and the wall thickness of the wind turbine foundation monopile 1 is 100mm.
[0060] The outer diameter of the fixed pile 2 is 2000mm-6000mm, preferably 4000mm; the wall thickness of the fixed pile 2 is 30mm-60mm, preferably 40mm; the pile length of the fixed pile 2 is 60000mm-100000mm, preferably 90000mm; and the depth of penetration into the soil (i.e., seabed) is 30000mm-40000mm, preferably 30000mm. The specific dimensions of each parameter can also be designed and adjusted together with the actual sea conditions and the actual wind turbine foundation monopile 1.
[0061] The specific dimensions of other related components are as follows:
[0062] The main function of the aquaculture platform deck 3 is to provide ample working and walking space for staff. Vertical telescopic mesh clamps 5 are installed at the bottom of the aquaculture platform deck 3 between the anchor piles 2, connecting adjacent anchor piles 2. The aquaculture platform deck 3 is made of steel and is positioned 10,000mm-20,000mm above the average sea level, preferably 10,000mm. The width of the aquaculture platform deck 3 is 4,000mm-8,000mm, preferably 6,000mm, thus ensuring sufficient working space.
[0063] The vertical telescopic net clamp 5 can roll up excess telescopic netting 4. When the telescopic netting 4 is subjected to ocean currents or waves, its tension increases, and the telescopic netting 4 inside the vertical telescopic net clamp 5 will extend under force to avoid prolonged stress on the telescopic netting 4, thus increasing its service life. The vertical telescopic net clamp 5 mainly controls the longitudinal expansion and contraction of the telescopic netting 4. The vertical telescopic net clamp 5 also has an important function: when the connection between the telescopic netting 4 and the horizontal telescopic net clamp 6 and the counterweight ring 8 is released, the vertical telescopic net clamp 5 can roll up the entire telescopic netting 4 to above sea level, which is beneficial for the regular inspection and maintenance of the telescopic netting 4. The diameter of the vertical telescopic mesh clamp 5 is 500mm-1000mm, preferably 700mm; the length is 30000mm-60000mm, preferably 50000mm; the two ends of the vertical telescopic mesh clamp 5 are connected to the fixed piles 2 to increase the overall structural stability and form a regular hexagonal aquaculture cage with a side length of 30000mm-60000mm, preferably a regular hexagonal aquaculture cage with a side length of 50000mm.
[0064] The horizontal telescopic mesh clamp 6 mainly controls the horizontal expansion and contraction of the telescopic mesh 4, and its working principle is the same as that of the vertical telescopic mesh clamp 5. Both ends of the horizontal telescopic mesh clamp 6 are connected to the upper part of the fixed pile 2 and the counterweight ring 8 on the seabed, respectively. The diameter of the horizontal telescopic mesh clamp 6 is 300mm-600mm, preferably 400mm; the length is 30000mm-60000mm, preferably 50000mm; six horizontal telescopic mesh clamps 6 form a stable aquaculture space with an effective aquaculture space of approximately 100000m². 3 -200000m 3 The preferred value is 150,000m. 3 .
[0065] The support rod 7 is used to connect the wind turbine foundation monopile 1 to the fixed piles 2, so that the aquaculture cage formed by the wind turbine foundation monopile 1 and the surrounding fixed piles 2 becomes an integral whole, jointly bearing environmental loads, improving the overall structural stability, reducing damage to the wind turbine foundation monopile 1 caused by long-term load, and extending the service life of the wind turbine foundation monopile 1. The support rod 7 is made of ultra-high strength alloy steel, with a diameter of 1000mm-2000mm, preferably 1500mm; and a length of 50000mm.
[0066] The cross-sectional diameter of the counterweight ring 8 is 2000mm-3000mm, preferably 2500mm; the ring diameter is 10000mm.
[0067] In this embodiment, the counterweight ring 8 includes two semi-circular rods, with their ends connected by flanges. The counterweight ring 8 serves to connect the telescopic netting 4 and the transverse telescopic netting clamps 6 to form the bottom of the aquaculture cage. The two semi-circular rods are solid structures to provide bottom counterweight, ensuring a tight fit against the seabed and allowing the aquaculture cage to form a closed system in the sea, preventing the cultured organisms from swimming out.
[0068] In this embodiment, fiber optic grating sensors are installed on the wind turbine foundation monopile 1, fixed pile 2, support rod 7, vertical telescopic mesh clamp 5 and horizontal telescopic mesh clamp 6. The purpose is to detect whether each component has deformed and to transmit the detection data to the control computer.
