[0036] In order for those skilled in the art to which the present application belongs to more clearly understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0037] At present, the construction of domestic offshore wind farms is in full swing, and the offshore wind resources are effectively developed, but the space utilization rate of the wind farm sea area is low. Therefore, the concept of wind-fish integration is gradually promoted and recognized by the national department, and the newly built offshore wind farm approval needs to carry out wind-fish integration pilot. However, the wind farm sea area has its unique hydrological environmental characteristics, such as strong wind, fast flow, large wave influence and frequent tidal level change, etc. The traditional polyethylene net cage and conventional steel aquaculture platform have poor wind and wave resistance in deep sea area, and have poor fish adaptability in such wind farm sea area environment.

[0038] In order to solve the technical problem of poor fish adaptability caused by fast seawater flow in the wind farm sea area in the related art, please refer to Figure 1 The present application provides a kind of offshore wind farm fishery breeding system, offshore wind farm fishery breeding system includes breeding platform 10, wind turbine foundation 20, marine product breeding zone 40 and access channel 50.

[0039] Breeding platform 10 is used for breeding fish, and the bred fish can include large yellow croaker, small yellow croaker and black seabream, etc. Wind turbine foundation 20 can be multiple, and multiple wind turbine foundations 20 are spaced around the outside of breeding platform 10, and adjacent wind turbine foundations 20 are connected by breeding rope system 30 to form breeding area. In this way, the existing wind turbine foundations 20 of the wind farm can be used to form a breeding area for fishery breeding, and the space utilization rate of the wind farm sea area can be improved.

[0040] Marine product breeding zone 40 is arranged on the inside of breeding rope system 30, and the inside is spaced from breeding platform 10, so that marine product breeding zone 40 is arranged around the side of breeding platform 10. The marine product can be laver, seaweed and kelp, etc. When the seawater with high flow rate passes through the marine product breeding zone 40, the laver, seaweed or kelp in the marine product breeding zone 40 can hinder the flow of seawater, and reduce the flow rate of seawater to a certain extent. Since fishery is suitable for breeding in sea area with low flow rate, the marine product breeding zone 40 hinders the flow of seawater, so that the internal flow rate of the water surrounded by breeding platform 10 is low, creating an environment suitable for fishery growth in the breeding area, improving the fishery adaptability of the wind farm area, and improving the space utilization rate of the wind farm sea area. At the same time, the laver, seaweed or kelp in the marine product breeding zone 40 can also provide abundant natural organic bait for fishery, which can improve the quality, taste and nutritional value of the bred fish to a certain extent.

[0041] By surrounding the marine product cultivation zone 40 around the cultivation platform 10, the marine product cultivation zone 40 can provide more abundant organic natural bait for fishery, and fish manure can provide organic fertilizer for algae, so as to realize the complementary integration of marine product cultivation and fishery cultivation. Meanwhile, the marine product cultivation zone 40 can effectively reduce the flow rate of seawater in the cultivation area of the wind farm, so that the internal flow rate of the water body surrounded by the cultivation platform 10 is low, and an environment suitable for the growth of fishery in the cultivation area is created, thereby improving the fishery suitability of the wind farm area. In this way, the blank of aquaculture in the wind farm can be filled, the utilization rate of the marine space in the wind farm area can be improved, and the development of the coastal marine economy can be promoted.

[0042] The access passage 50 is arranged in the area where the marine product cultivation zone 40 is located, and is connected to the outside area of the cultivation platform 10 and the cultivation area. The access passage 50 is reserved for the supply ship to pass through, so that the supply ship can transport feed and other materials to the cultivation platform 10 through the access passage 50, thereby providing a strong material guarantee for the orderly development of the cultivation platform 10.

[0043] The outer side of the marine product cultivation zone 40 is arranged on the inner side of the cultivation rope system 30, and the cultivation rope system 30 is connected to the wind turbine foundation 20 of the wind farm, so as to improve the space utilization rate of the sea area of the wind farm. The cultivation platform 10 is located in the internal area of the marine product cultivation zone 40, and the marine product cultivation zone 40 can absorb and reduce the flow to some extent, so as to provide a suitable growth environment for fishery cultivation. Meanwhile, the cultivation of marine products can provide natural organic bait for the fry in the cultivation platform 10, and fish manure can provide organic fertilizer for marine products, so as to realize the complementary integration of marine product cultivation and fishery cultivation, and improve the quality of marine products and fish.

[0044] Please refer to Figure 1 , the wind turbine foundation 20 can be four, and the adjacent four wind turbine foundations 20 are taken as a cultivation unit, so that the cultivation rope system 30 connected to the wind turbine foundation 20 can be surrounded to form a square, and the cultivation platform 10 is located at the middle position of the square cultivation rope system 30. The outer side of the marine product cultivation zone 40 is arranged on the inner side of the cultivation rope system 30, so that the marine product cultivation zone 40 can also be arranged in the square direction, and is surrounded on the side of the cultivation platform 10.

[0045] It should be noted that the shape of the cultivation rope system 30 can be set according to the distribution form of the original wind turbine foundation 20 surrounded on the side of the cultivation platform 10, and the specific setting can be made according to the actual needs, which is not limited in the present application.

[0046] The marine product cultivation zone 40 can be provided with multiple layers and is sequentially sleeved on the circumferential side of the cultivation platform 10. Since the marine product cultivation zone 40 can break waves and reduce flow to some extent, the multiple layers of the marine product cultivation zone 40 can further reduce the flow of seawater in the cultivation area of the wind farm, so that the internal flow rate of the water surrounded by the cultivation platform 10 is low, and the fishery located in the cultivation platform 10 can ensure a more suitable growth environment. At the same time, the marine product cultivation zone 40 can provide natural organic bait for the fry in the cultivation net cage, and fish feces can provide organic fertilizer for the growth of marine products, realizing the complementary integration of marine product cultivation and fishery cultivation and improving the quality of marine products and fish.

[0047] Understandably, the cultivation rope system 30 can include a first pull rope (not shown in the figure) made of polypropylene material and a floating ball (not shown in the figure), and the floating ball is connected to the first pull rope or the first pull rope is arranged in the floating ball, so that the first pull rope can be relatively stably floated on the sea surface under the action of the floating ball. The first pull rope is connected between the adjacent two wind turbine foundations 20, and the wind turbine foundation 20 provides an attachment point for the first pull rope and a pulling force for the first pull rope, so that the first pull rope can form a cultivation area around the circumferential side of the cultivation platform 10.

[0048] The marine product cultivation zone 40 includes a second pull rope (not shown in the figure), an attachment rope (not shown in the figure), and a second floating ball (not shown in the figure), and the second floating ball is connected to the second pull rope or the second pull rope is arranged in the second floating ball, so that the second pull rope can be relatively stably floated on the sea surface under the action of the buoyancy of the second floating ball. The two ends of the second pull rope are respectively connected to the two ends of the first pull rope, so that the first pull rope can provide an attachment point for the second pull rope. The attachment rope can be provided with multiple attachment ropes, and one end of the attachment rope is connected to the second pull rope, and the other end extends vertically into the seawater, so that the marine products (such as seaweed, algae, or kelp, etc.) can be attached to the attachment rope to form the marine product cultivation zone 40. In order to improve the wave-breaking and flow-reducing effect of the marine product cultivation zone 40, the distance between the adjacent two attachment ropes can be reduced, the planting density of the marine products can be increased, the flow rate of seawater in the cultivation area of the wind farm can be further reduced, and the fishery suitability of the wind farm can be improved. In some embodiments, the distance between the adjacent two attachment ropes can be set according to the flow rate of seawater in the wind farm, and the present application is not limited.

[0049] It should be noted that the multi-layered marine product cultivation zone 40 can be cross-zoned for seed release. Understandably, two adjacent marine product cultivation zones 40 can be used for releasing different types of marine products. According to cultivation experience, for example, for kelp, the width of a single kelp cultivation zone should be no less than 50 meters. Two kelp cultivation zones with a width of more than 50 meters can achieve a wave reduction and flow reduction effect of about 60%, and four kelp cultivation zones with a width of more than 50 meters can achieve a wave reduction and flow reduction effect of about 80%. In this way, the seawater passing through the four kelp cultivation zones reaches the cultivation platform 10 (fish cultivation zone) located in the middle position, so that the internal flow rate of the water body surrounded by the cultivation platform 10 is low, ensuring a more suitable growth environment for the fish in the cultivation platform 10. At the same time, the marine product cultivation zone 40 can provide natural organic bait for the fry in the cultivation net cage, and fish feces can provide organic fertilizer for the growth of marine products, achieving complementary integration of marine product cultivation and fish cultivation and improving the quality of marine products and fish.

[0050] In some embodiments, the multi-layered marine product cultivation layer can also cultivate the same type of marine product. The specific setting can be based on actual needs, and the present application does not make specific limitations.

[0051] In order to improve the stability of the position of the marine product cultivation zone 40 in seawater, the offshore wind farm fish cultivation system can further include a plurality of positioning piles. The plurality of positioning piles are arranged along the vertical direction, and one end of the positioning piles is inserted into the seabed, so that the positioning piles are more stably installed at the set position in seawater. The second pulling rope in the marine product cultivation zone 40 can be connected to the other end of the positioning pile, so that the positioning pile can more stably support the marine product cultivation zone 40. It should be noted that the position of the positioning pile can be set according to the position of the marine product cultivation zone 40, and the present application does not make specific limitations.

[0052] Further, please refer to Figure 2 The cultivation platform 10 can include a platform frame 11, a net 12, and a pile leg 13 arranged along the vertical direction. The net 12 is located in the platform frame 11, and the net 12 can cultivate large yellow croaker, small yellow croaker, black seabream, and the like. The net 12 can be arranged in at least two layers, which can slow down the flow rate of seawater to a certain extent, so that the net 12 is suitable for fish cultivation and improves the fish suitability of the cultivation platform 10.

[0053] The pile legs 13 are arranged at least in three, and distributed on the periphery of the platform frame 11, which improves the support stability of the platform frame 11 and maintains the stability of the aquaculture platform 10 in high flow speed seawater, so as to improve the fishery adaptability of the aquaculture platform 10. The platform frame 11 can be arranged as a hollow frame, and the platform frame 11 is provided with a water inlet valve and a water outlet valve. When the aquaculture platform 10 is in operation (the net 12 in the platform frame 11 needs to be sunk into the sea to breed fry), the water inlet valve is opened, so that seawater can enter the hollow structure of the platform frame 11, and the pile legs 13 can be inserted into the deep soil layer of the seabed under the action of gravity, so that the aquaculture platform 10 can be stably seated on the seabed in more extreme marine environment conditions, which improves the stability of the aquaculture platform 10 in seawater and also ensures the stability of the position of the aquaculture platform 10 in seawater. When the aquaculture platform 10 is not in operation (the net 12 in the platform frame 11 needs to be floated to catch fish), the water outlet valve is opened, so that the platform frame 11 floats to the set position under the action of buoyancy to facilitate fish catching. At the same time, the water discharge amount can be controlled to control the floating height of the platform frame 11, and when the platform frame 11 floats to the height required for fish catching, the water outlet valve can be closed. The water discharge amount of the water outlet valve can be set according to actual needs, which is not limited in the present application.

[0054] It should be noted that a support structure is arranged between the two adjacent pile legs 13, which is an inner hollow structure, which can improve the connection strength between the two adjacent pile legs 13, and also improve the stability of the platform frame 11.

[0055] The aquaculture platform 10 is fixed by the bottom seating pile, which is more flexible and reliable than the anchoring system. At the same time, the bottom seating pile can prevent the "anchor walking" phenomenon, and the use of the bottom seating pile in the wind power field can improve the stability of the aquaculture platform 10, which is safe and reliable.

[0056] It should be noted that the pile legs 13 can be arranged in multiple and arranged on the periphery of the aquaculture platform 10, and the number of the pile legs 13 can be set according to actual needs, which is not limited in the present application. The diameter of the pile legs 13 and the water amount required in the floating box 111 for inserting into the seabed soil layer need to be calculated according to the horizontal force received by the aquaculture platform 10 and the seabed rock and soil information, which is not limited in the present application.

[0057] Further, please refer to Figures 2-3, the platform frame 11 can be a ship-shaped frame structure, and specifically can include a floating box 111 located at the bottom, a walkway 112 located at the top, and a column 113 for connecting the floating box 111 and the walkway 112. The floating box 111 is a hollow plate frame structure with a rectangular cross section, and the displacement of the floating box 111 can control the buoyancy requirement of the aquaculture platform 10 for operations such as floating, net changing, maintenance, and fish harvesting. The walkway 112 can be connected to the floating box 111 through the column 113, which is vertically arranged to support the walkway 112, and the walkway 112 is located on the floating box 111. The column 113 is a hollow structure with a circular cross section, which can improve the strength of the column 113 to some extent, improve the stability of the column 113 supporting the walkway 112, and ensure the stability of the aquaculture platform 10 during the sinking and floating process of the aquaculture platform 10.

[0058] It should be noted that, referring to Figure 2 , the hollow space of the floating box 111 can be in communication with the hollow space in the column 113, increasing the water intake of the platform frame 11, improving the sinking force of the platform frame 11, and improving the bottom stability of the platform frame 11. It can also increase the displacement of the platform frame 11, improve the buoyancy of the platform frame 11, and improve the floating speed of the platform frame 11.

[0059] Referring to Figures 2-3 , the aquaculture platform 10 further comprises a corrugated plate 14, which is arranged in the vertical direction and located near the top of the platform frame 11 inside the platform frame 11. The corrugated plate 14 is connected to the platform frame 11, and the corrugated plate 14 is a corrugated sheet and is welded to the platform frame 11, improving the connection stability between the corrugated plate 14 and the platform frame 11. The netting 12 is located near the bottom of the platform frame 11 inside the platform frame 11, that is, the netting 12 and the corrugated plate 14 are arranged in the vertical direction of the aquaculture platform 10 from bottom to top. In this way, the netting 12 and the corrugated plate 14 form a water level fluctuation area. The corrugated plate 14 is provided with a plurality of through holes, and the distance between adjacent through holes and the diameter of the through holes can be calculated according to the water dynamics of the water level fluctuation area. In this way, the flow rate of seawater in the water level fluctuation area can be reduced to some extent, the internal flow rate of the water body surrounded by the aquaculture platform 10 is low, and a suitable environment for fish farming is created.

[0060] It should be noted that the netting 12 can be arranged in two or more layers and located below the water level fluctuation area. Reducing the flow rate of the water body surrounded by the aquaculture platform 10 can also ensure that the water body surrounded by the aquaculture platform 10 has a certain flow rate, which is beneficial to the exchange of water in the netting 12. Fish manure can be brought to marine products through the flow of water, providing nutrients for the growth of marine products. At the same time, due to the flow of water, organic fertilizer produced by marine products can also flow into the netting 12, providing nutrients to the fry, which is helpful for the growth of the fry.

[0061] In some embodiments, the corrugated plates 14 can be provided in multiple pieces and stacked together, and the corrugated plates 14 are respectively connected to the platform frame 11, and the multiple corrugated plates 14 correspond to the directions on the aquaculture platform 10 that are more affected by the flow rate, so as to reduce the influence of the flow rate of seawater on the flow rate of water in the water body surrounded by the aquaculture platform 10.

[0062] In some embodiments, the corrugated plates 14 can also be provided in multiple pieces and arranged around the periphery of the platform frame 11, and the corrugated plates 14 are respectively connected to the platform frame 11, which can reduce the influence of the flow rate of seawater in each direction around the platform frame 11 on the flow rate of water in the water body surrounded by the aquaculture platform 10, so as to provide a suitable growth environment for fish farming in the aquaculture platform 10.

[0063] The offshore wind farm aquaculture system also includes a photovoltaic power generation system 15, please refer to Figures 2-3 The photovoltaic power generation system 15 includes a photovoltaic support, a photovoltaic panel and an energy storage device, and the photovoltaic support, the photovoltaic panel and the energy storage device are arranged on the walkway 112. The photovoltaic power generation system 15 provides clean energy and reduces environmental pollution; at the same time, it can provide power for the lighting and video monitoring of the aquaculture platform 10. The aquaculture platform 10 has high automation, and the use of light energy can realize the self-sufficiency of the energy of the aquaculture platform 10, thereby improving the automation and cleanliness of the aquaculture platform 10 to a certain extent.

[0064] The aquaculture platform 10 is provided with the photovoltaic power generation system 15, and the electric energy generated by the photovoltaic power generation system 15 can meet the needs of the operation of the aquaculture platform 10, and at the same time, the wind turbine can also provide electric energy (the electric energy provided by the wind turbine can be connected to the aquaculture platform 10 through the submarine cable) to the aquaculture platform 10, so as to solve the problem of excess power generation of wind power. In this way, the use of traditional fuel power generation systems can be avoided, so that the aquaculture platform 10 can realize "zero carbon emission" during the aquaculture period, thereby reducing the pollution to the environment to a certain extent.

[0065] It should be noted that the walkway 112 can be a grid structure to meet the needs of personnel walking. At the same time, the photovoltaic support is installed on the walkway 112, and the high photovoltaic support can also shield the upper building 18 to a certain extent while supporting the photovoltaic panel.

When the culture platform 10 is in operation, the position of the sea level in the vertical direction of the platform frame 11 is the position of the boarding platform 16 in the vertical direction of the platform frame 11, which can be set according to the depth of different sea areas, and the present application is not limited in particular.

[0067] In some embodiments, the boarding platform 16 can be located at and parallel to the sea level, or located above and close to the sea level during the operation of the culture platform 10, to facilitate personnel landing and cargo loading and unloading.

[0068] The inclined ladder 17 is located between the boarding platform 16 and the walkway 112, one end of the inclined ladder 17 is connected with the boarding platform 16, and the other end is connected with the walkway 112, to facilitate personnel on the boarding platform 16 to reach the walkway 112 through the inclined ladder 17.
