DETAILED DESCRIPTION

[0045] 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.

[0046] The purpose of the present invention is to provide a wind-fishing integrated breeding device and an installation method thereof that can extend the life of offshore wind turbines and prevent collisions, so as to solve the problems existing in the above-mentioned prior art. A plurality of fixed piles are arranged, so as to reduce the burden on the wind turbine foundation pile and increase its service life. The fixed piles can also protect the wind turbine foundation pile and prevent the wind turbine foundation pile from being hit by marine objects.

[0047] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] Embodiment 1

[0049] like Figure 1-Figure 5As shown, this embodiment provides a wind-fishing integrated breeding device for extending the life of offshore wind turbines and preventing collisions, including a wind turbine foundation pile 1. The upper end of the wind turbine foundation pile 1 is used to install wind power generation equipment. The wind power generation equipment is a prior art, so its specific structure is not described in detail here. A plurality of fixed piles 2 are arranged around the wind turbine foundation pile 1. The wind turbine foundation pile 1 and each fixed pile 2 are connected by a support rod 7, respectively. The wind turbine foundation pile 1 and the fixed pile 2 are connected as a whole by the support rod 7. A breeding platform deck 3 is arranged between the wind turbine foundation pile 1 and each fixed pile 2 and between two adjacent fixed piles 2, and a corresponding support rod 7 is arranged on the lower surface of the breeding platform deck 3 between the wind turbine foundation pile 1 and the fixed pile 2. A net vertical telescopic net clamp 5 is provided on the lower surface of the aquaculture platform deck 3 between two adjacent fixed piles 2, and a counterweight ring 8 is sleeved on the outer side of the fan foundation pile 1. The inner diameter of the counterweight ring 8 is larger than the outer diameter of the fan foundation pile 1, so the counterweight ring 8 is not in direct contact with the fan foundation pile 1. The counterweight ring 8 is located below the aquaculture platform deck 3. Specifically, the counterweight ring 8 is located on the seabed during actual use. A telescopic net 4 is provided between each net vertical telescopic net clamp 5 and the counterweight ring 8. The net vertical telescopic net clamp 5 and the counterweight ring 8 are respectively connected to the upper and lower ends of the telescopic net 4. A net transverse telescopic net clamp 6 is respectively connected to the left and right sides of each telescopic net 4. The upper end of the net transverse telescopic net clamp 6 is fixed to a corresponding fixed pile 2, and the lower end of the net transverse telescopic net clamp 6 is fixed to the counterweight ring 8.

[0050] In actual use, multiple fixed piles 2 can effectively share part of the load for the wind turbine foundation pile 1, thereby extending the service life of the wind turbine foundation pile 1. It can also resist part of the submarine current for the wind turbine foundation pile 1, thereby improving the stability of the wind turbine foundation pile 1. In addition, the fixed piles 2 can also prevent the wind turbine foundation pile 1 from being hit by marine objects. The telescopic net 4 has its own telescopic ability, so it can stretch when facing a large ocean current, thereby alleviating the impact of the ocean current, thereby increasing the service life of the telescopic net 4.

[0051] In this embodiment, a platform handrail 10 is installed on the breeding platform deck 3 to ensure the safety of the staff. The material is aluminum alloy, and the 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 aquaculture platform deck 3, and the upper end of the ladder is located at the bottom of the equipment room 9. The staff can enter through the bottom ladder. The equipment room 9 can meet the placement of related equipment, such as monitoring equipment, fishing equipment, etc. The diameter of the equipment room 9 is 5000mm-8000mm, preferably 8000mm, and the height is 3000mm-4000mm, preferably 4000mm. The equipment room 9 adopts an assembled construction method as a whole, is processed in a coastal factory, and is directly assembled on the fixed pile 2.

[0053] In this embodiment, there are six fixed piles 2, telescopic nets 4, net vertical telescopic net clips 5 and net horizontal telescopic net clips 6. From a top view, the six net vertical telescopic net clips 5 can form a regular hexagon, and the six fixed piles 2 are respectively located at its six vertices. The telescopic net 4 is made of ultra-high molecular weight polyethylene fiber material. The upper end of each telescopic net 4 is connected to a net vertical telescopic net clip 5, and a net horizontal telescopic net clip 6 is provided on both sides. The lower end is connected to a counterweight ring 8, and the six telescopic nets 4 together form a breeding cage.

[0054] In this embodiment, if Figure 4 As shown, the vertical telescopic net clip 5 of the net includes a vertical net clip shell, which is a cylindrical shell. A vertical expansion joint is provided on the vertical net clip shell, and a vertical telescopic shaft is rotatably connected in the vertical net clip shell. One end (upper end) of the telescopic net 4 is wound on the vertical telescopic shaft, and the vertical telescopic shaft is connected to the inner wall of the vertical net clip shell through a vertical reset torsion spring. One end of the vertical reset torsion spring is connected to the vertical telescopic shaft, and the other end is connected to the inner wall of the vertical net clip shell. When there is a large ocean current, the ocean current will push the telescopic net 4 to stretch out, and the telescopic net 4 in the vertical net clip shell will continue to stretch out, and the vertical reset torsion spring will store energy; when the ocean current flows away and there is no large external force, under the action of the elastic potential energy of the vertical reset torsion spring, the vertical telescopic net clip 5 of the net will retract part of the telescopic net 4 again.

[0055] like Figure 5As shown, the net transverse telescopic net clip 6 includes a transverse net clip shell, and a transverse expansion joint is respectively provided on both sides of the transverse net clip shell, and a transverse telescopic shaft is rotatably connected in the transverse net clip shell. The adjacent ends of the telescopic nets 4 on both sides of the net transverse telescopic net clip 6 are wound together on a transverse telescopic shaft. When the transverse telescopic shaft rotates, the telescopic nets 4 on both sides can be extended or retracted at the same time. The transverse telescopic shaft is connected to the inner wall of the transverse net clip shell through a transverse reset torsion spring. When there is a large ocean current, the ocean current will push the telescopic net 4 to stretch out, and the two telescopic nets 4 in the transverse net clip shell will continue to stretch out, and the transverse reset torsion spring will store energy; when the ocean current flows away and there is no large external force, under the action of the elastic potential energy of the transverse reset torsion spring, the net transverse telescopic net clip 6 will retract part of the telescopic nets 4 on both sides again.

[0056] The vertical mesh clamp shell and the horizontal mesh clamp shell are both made of steel, with a strong structure and low manufacturing cost.

[0057] In this embodiment, the two ends of the support rod 7 are connected to the fan foundation pile 1 and the fixed pile 2 through flanges, respectively. The flange connection can be easily installed and replaced, and has a longer service life than welding and other methods. The fan foundation pile 1 and the aquaculture cage form a community, and the fan foundation pile 1 and the fixed pile 2 transmit force through the support rod 7 to achieve common environmental loads, increase the stability of the fan foundation pile 1, and extend its service life. The size and material of the fan foundation pile 1 are determined by the actual project, and the "wind-fishing integration" integrated structural system is comprehensively considered during the design.

[0058] In this embodiment, the wind turbine foundation pile 1 and the fixed pile 2 are both in the shape of steel pipes, and their specific dimensions are as follows:

[0059] The outer diameter of the wind turbine foundation pile 1 is 8000 mm, and the wall thickness of the wind turbine foundation pile 1 is 100 mm.

[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; the depth of the soil (i.e., seabed) is 30000mm-40000mm, preferably 30000mm. The specific size of each parameter can also be designed and adjusted according to the actual sea conditions and the actual wind turbine foundation pile 1.

[0061] The specific dimensions of other related parts are as follows:

[0062] The main function of the aquaculture platform deck 3 is to provide sufficient working and walking space for the staff to carry out related work. The lower part of the aquaculture platform deck 3 between the fixed piles 2 is installed with a net vertical telescopic net clip 5, which is connected with two adjacent fixed piles 2. The aquaculture platform deck 3 is made of steel, and is 10000mm-20000mm from the average sea level, preferably 10000mm; the aquaculture platform deck 3 is 4000mm-8000mm wide, preferably 6000mm, so as to ensure sufficient working space.

[0063] The net vertical telescopic net clip 5 can roll in the extra telescopic net 4. When the telescopic net 4 is affected by ocean currents or waves, its tension increases, and the telescopic net 4 in the net vertical telescopic net clip 5 will be stretched out by force to avoid the telescopic net 4 being stressed for a long time and increase the service life of the telescopic net 4. The net vertical telescopic net clip 5 mainly controls the longitudinal expansion and contraction of the telescopic net 4. The net vertical telescopic net clip 5 also has an important function, that is, when the connection between the telescopic net 4 and the net horizontal telescopic net clip 6 and the counterweight ring 8 is untied, the net vertical telescopic net clip 5 can roll up the entire telescopic net 4 to reach above the sea level, which is conducive to the regular inspection and maintenance of the telescopic net 4. The diameter of the vertical telescopic net clip 5 of the net is 500mm-1000mm, preferably 700mm; the length is 30000m-60000mm, preferably 50000mm; the two ends of the vertical telescopic net clip 5 of the net are interconnected with the fixed piles 2 to increase the stability of the overall structure, forming a regular hexagonal breeding cage with a side length of 30000mm-60000mm, preferably a regular hexagonal breeding cage with a side length of 50000mm.

[0064] The horizontal telescopic net clip 6 mainly controls the horizontal telescopic net 4, and the realization principle is the same as that of the vertical telescopic net clip 5. The two ends of the horizontal telescopic net clip 6 are respectively connected to the upper part of the fixed pile 2 and the counterweight ring 8 on the seabed. The diameter of the horizontal telescopic net clip 6 is 300mm-600mm, preferably 400mm; the length is 30000m-60000mm, preferably 50000mm; six horizontal telescopic net clips 6 enclose a stable breeding space with an effective breeding space of about 100000m 3 -200000m 3 , preferably 150000m 3 .

[0065] The support rod 7 is used to connect the fan foundation pile 1 with the fixed pile 2, so that the fan foundation pile 1 and the surrounding fixed piles 2 form a whole breeding cage, jointly bear the environmental load, improve the overall stability of the structure, reduce the damage caused by the fan foundation pile 1 under long-term load, and extend the service life of the fan foundation pile 1. The material of the support rod 7 is ultra-high strength alloy steel, with a diameter of 1000mm-2000mm, preferably 1500mm; the length is 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 weight ring 8 includes two semicircular rods, and the two ends of the two semicircular rods are connected by flanges. The weight ring 8 is used to connect the telescopic net 4 and the transverse telescopic net clip 6 of the net to form the bottom of the aquaculture cage. The two semicircular rods are solid structures to achieve bottom weighting, so that it fits tightly to the seabed, so that the aquaculture cage forms a closed whole in the sea to prevent the cultured organisms from swimming out.

[0068] In this embodiment, fiber optic Bragg grating sensors are installed on the wind turbine foundation pile 1, fixed pile 2, support rod 7, vertical telescopic net clamp 5 and horizontal telescopic net clamp 6. The purpose is to detect whether each component is deformed and transmit the detection data to the control computer.
