[0038] The present invention provides an ocean ranching system 100 applied to an offshore monopile foundation 200.

[0039] Please refer to Figure 1 and Figure 2 In some embodiments of the ocean ranching system 100 applied to the offshore monopile foundation 200 of the present invention, the ocean ranching system 100 includes:

[0040] A platform 10 located above the sea surface and used to surround the offshore monopile foundation 200;

[0041] A driving device 20 provided on the platform 10; and

[0042] A net cage assembly 30 provided below the platform 10 and drivingly connected to the driving device 20 to move up and down in the vertical direction under the drive of the driving device 20.

[0043] In this embodiment, the ocean ranching system 100 includes a platform 10, a driving device 20, and a net cage assembly 30. Among them, the platform 10 is arranged above the sea surface and is circumferentially arranged around the offshore monopile foundation 200 to serve as the operation basis of the ocean ranching system 100; the driving device 20 is provided on the platform 10, and the net cage assembly 30 is provided below the platform 10 and is drivingly connected to the driving device 20. Thus, the driving device 20 can provide power for the lifting movement of the net cage assembly 30, so that the net cage assembly 30 can sink into the sea water under the drive of the driving device 20 for aquaculture operations, or the net cage assembly 30 can rise to the vicinity of the sea surface under the drive of the driving device 20 for fishing operations.

[0044] It should be noted that an ocean ranch refers to an artificial fishing ground set up in a specific sea area for the planned cultivation and management of fishery resources. Among them, the ocean ranch net cage is the core structure of the ocean ranch. In the existing related technologies, the ocean ranch net cage often needs to be fixed at a designated position through an anchoring system, which has problems such as high anchoring difficulty and high cost.

[0045] Therefore, it can be understood that the offshore monopile foundation 200, as a foundation form most widely used in the field of offshore wind power engineering, has been widely applied. The ocean ranching system 100 of the technical solution of the present invention is set with the offshore monopile foundation 200 as the fixed foundation, which can reduce the anchoring cost and anchoring difficulty of the ocean ranching system 100, and can drive the net cage assembly 30 to move up and down in the sea water through the driving device 20 to realize the full-depth seawater aquaculture of the ocean ranching system 100.

[0046] Please refer to Figure 1, in some embodiments of the ocean ranching system 100 where the invention is applied to an offshore monopile foundation 200, the driving device 20 includes a number of first lifting components 21. One end of each first lifting component 21 is disposed on the platform 10, and the other end extends vertically downward towards the seabed. The number of first lifting components 21 are arranged in a circumferential arrangement around the offshore monopile foundation 200;

[0047] The net cage assembly 30 includes a number of net cages 31 arranged in sequence along the vertical direction. The net cages 31 are arranged in a circumferential arrangement around the offshore monopile foundation 200. Each net cage 31 is in driving connection with one of the first lifting components 21 to move up and down in the vertical direction under the drive of the first lifting component 21.

[0048] In this embodiment, the driving device 20 includes a number of first lifting components 21. One end of each first lifting component 21 is disposed on the platform 10, and the other end extends vertically downward towards the seabed. The number of first lifting components 21 are arranged in a circumferential arrangement around the offshore monopile foundation 200. The net cage assembly 30 is disposed in the lower region of the platform 10 and is used to realize the aquaculture function of marine organisms. The net cage assembly 30 includes a number of net cages 31 arranged in sequence along the vertical direction. The net cages 31 are arranged in a circumferential arrangement around the offshore monopile foundation 200, and each net cage 31 is in driving connection with a lifting component, so that each net cage 31 can independently move up and down in the vertical direction under the drive of a lifting component. With such an arrangement, the net cages 31 can be driven by the driving device 20 to penetrate into the underwater space of the offshore monopile foundation 200 for seawater aquaculture, or move towards the sea surface under the drive of the driving device 20 to facilitate the fishing of marine organisms in the net cages 31. Moreover, by arranging a plurality of net cages 31 in the vertical direction, full-depth seawater aquaculture can also be realized, thereby making full use of the underwater space of the offshore monopile foundation 200 and saving marine resources.

[0049] Specifically, in some embodiments, the first lifting component 21 can be set as a first drive shaft and a first driving member. The first drive shaft extends vertically downward, and the first driving member is used to drive the net cage 31 disposed on the first drive shaft to reciprocate along the length direction of the first drive shaft. The first lifting component 21 can also be set as a first telescopic mechanism. One end of the first telescopic mechanism is disposed at the bottom of the platform 10, and the other end extends vertically downward and is connected to the net cage 31, and is telescopically arranged in the vertical direction to drive the net cage 31 to dive when the first telescopic mechanism extends downward and drive the net cage 31 to float when the first telescopic mechanism retracts upward. The first lifting component 21 can also include a pulley and a cable, and the cable is pulled up or down through the pulley to drive the net cage 31 to move up and down. The specific implementation manner can be set according to actual needs and will not be limited herein.

[0050] Please refer to Figure 1, in some embodiments of the ocean ranching system 100 where the invention is applied to the offshore monopile foundation 200, the net cage 31 includes a plurality of net cage units 311. The plurality of net cage units 311 are arranged circumferentially around the offshore monopile foundation 200. Two adjacent net cage units 311 are detachably connected, and at least one net cage unit 311 is in driving connection with the first lifting assembly 21.

[0051] In this embodiment, the net cage 31 includes a plurality of net cage units 311. The plurality of net cage units 311 are arranged circumferentially around the offshore monopile foundation 200. Two adjacent net cage units 311 are detachably connected so that the plurality of net cage units 311 can be sequentially connected to form the net cage 31, and thus can move up and down synchronously under the drive of the first lifting assembly 21.

[0052] Specifically, in some embodiments, by connecting one of the net cage units 311 of the net cage 31 to the first lifting assembly 21 in a driving manner, the net cage 31 can be moved up and down in the vertical direction under the drive of the first lifting assembly 21. Of course, it is also possible that the first lifting assembly 21 includes a plurality of first lifting members, and the plurality of first lifting members are arranged at intervals circumferentially around the net cage 31 to be respectively in driving connection with a net cage unit 311. The first lifting assembly 21 can drive a plurality of net cage units 311 of the net cage 31 to move up and down simultaneously. Such a setting is beneficial to improving the connection stability between the first lifting assembly 21 and the net cage 31. The specific implementation manner can be set according to actual needs and will not be limited here.

[0053] It can be understood that by setting the net cage 31 as a plurality of net cage units 311 that are detachably connected to each other, on the one hand, the net cage 31 can be disassembled into a plurality of net cage units 311 with smaller volumes for transportation, which is beneficial to improving the transportation convenience of the net cage 31. On the other hand, when a part of the net cage 31 is damaged, the corresponding net cage unit 311 can be replaced or maintained specifically, thereby reducing the maintenance cost of the net cage 31. Moreover, by dividing the net cage 31 into a plurality of separate net cage units 311, different marine organisms can be cultured using different net cage units 311, thus improving the practicability of the ocean ranching system 100.

[0054] Please refer to Figure 3 , in some embodiments of the ocean ranching system 100 where the invention is applied to the offshore monopile foundation 200, the net cage unit 311 includes a frame 3111, and the frame 3111 includes:

[0055] Side frames 3111a. There are two side frames 3111a. The two side frames 3111a are arranged vertically and are spaced circumferentially around the offshore monopile foundation 200. Each side frame 3111a is detachably connected to the side frame 3111a of an adjacent net cage unit 311;

[0056] An arc-shaped inner ring 3112b, there are two of the arc-shaped inner rings 3112b, the arc-shaped inner rings 3112b are horizontally arranged, both ends of the arc-shaped inner rings 3112b are respectively connected to the two side frames 3111a, the two arc-shaped inner rings 3112b are arranged at intervals in the vertical direction, and the arc-shaped inner rings 3112b are in transmission connection with the first lifting assembly 21; and

[0057] An arc-shaped outer ring 3113c, there are two of the arc-shaped outer rings 3113c, the arc-shaped outer rings 3113c are horizontally arranged, both ends of the arc-shaped outer rings 3113c are respectively connected to the two side frames 3111a, and the two arc-shaped inner rings 3112b are arranged at intervals in the vertical direction.

[0058] In this embodiment, the net cage unit 311 includes a frame body 3111, and the frame body 3111 is formed by connecting two side frames 3111a, two arc-shaped inner rings 3112b and two arc-shaped outer rings 3113c. Specifically, the side frames 3111a are arranged in the vertical direction, the two side frames 3111a are arranged at intervals in the circumferential direction of the offshore monopile foundation 200, and the side frames 3111a of adjacent two net cage units 311 are detachably connected to each other so that a plurality of net cage units 311 can be sequentially connected and enclosed to form a net cage 31; the arc-shaped inner rings 3112b are arranged between the two side frames 3111a, both ends of the arc-shaped inner rings 3112b are respectively connected to the two side frames 3111a, and the two arc-shaped inner rings 3112b are arranged at intervals in the vertical direction to be respectively connected to the top and bottom ends on one side of the side frames 3111a facing the offshore monopile foundation 200; the arc-shaped outer rings 3113c are arranged between the two side frames 3111a, both ends of the arc-shaped outer rings 3113c are respectively connected to the two side frames 3111a, and the two arc-shaped outer rings 3113c are arranged at intervals in the vertical direction to be respectively connected to the top and bottom ends on one side of the side frames 3111a away from the offshore monopile foundation 200.

[0059] In some embodiments, the radius of curvature of the arc-shaped inner ring 3112b is greater than the radius of the offshore monopile foundation 200, and there is an interval between the arc-shaped inner ring 3112b and the offshore monopile foundation 200, whereby the friction between the net cage 31 and the offshore monopile foundation 200 can be reduced to facilitate the lifting movement of the net cage 31, and moreover, the installation gap between the arc-shaped inner ring 3112b and the offshore monopile foundation 200 can also provide installation space for other structures of the marine ranching system 100 such as the first lifting assembly 21, the vacuum pumping assembly 50, etc.

[0060] It should be noted that the cage unit 311 further includes a netting, which is disposed around the outside of the cage unit 311 in an openable and closable manner. When the netting is closed, it can ensure the fluidity of the water body in the inner and outer spaces of the cage unit 311 while preventing marine organisms from entering and leaving the cage unit 311, so as to achieve the purpose of marine aquaculture; when the cage unit 311 moves to the sea surface, the netting can also be opened to facilitate the fishing of the marine organisms therein, without the need to use fishing equipment such as fish pumps, improving the convenience of use of the marine ranch system 100.

[0061] Please refer to Figure 3 , in some embodiments of the marine ranch system 100 where the invention is applied to the offshore monopile foundation 200, the side frame 3111a includes four connecting rods connected end to end in sequence, and at least one of the connecting rods is provided with a connecting structure 3112, and the connecting structure 3112 is detachably connected to the connecting rod of the adjacent side frame 3111a.

[0062] In this embodiment, the side frame 3111a includes four connecting rods connected end to end in sequence. The four connecting rods are arranged in pairs opposite to each other, and at least one connecting rod is provided with a connecting structure 3112. Among them, it can be that only two adjacent connecting rods are connected and fixed through a single connecting structure 3112; of course, it can also be that several connecting structures 3112 cooperate to connect two adjacent connecting rods. At this time, several connecting structures 3112 can be arranged at intervals in sequence along the length direction of the connecting rod and can be detachably connected to the connecting rods of the adjacent side frame 3111a in sequence.

[0063] It should be noted that connecting two adjacent connecting rods through several connecting structures 3112 is beneficial to improving the connection stability between the two adjacent connecting rods. Among them, several connecting structures 3112 can be arranged on one of the two adjacent connecting rods, and of course, it can also be that a part of several connecting structures 3112 is arranged on one of the two adjacent connecting rods, and the rest is arranged on the other of the two adjacent connecting rods. In this way, it is beneficial to avoid interference between several connecting structures 3112 on adjacent cage units 311 during assembly; the specific implementation method can be set according to actual needs and is not limited here.

[0064] Specifically, in a feasible implementation manner, the connecting structure 3112 includes a main body portion and a connecting portion. Among them, the main body portion has a hollow cylindrical structure and is sleeved on one of the two adjacent connecting rods; the connecting portion is provided on the main body portion and is rotatably connected to the main body portion. The end of the connecting portion away from the main body portion is provided with a buckle structure for buckling and connecting to the other of the two adjacent connecting rods, thereby realizing the detachable connection between adjacent cage units 311.

[0065] Please refer to Figure 2, in some embodiments of the ocean ranching system 100 where the invention is applied to the offshore monopile foundation 200, a guiding ring 3113 is provided on the side of the arc-shaped inner ring 3112b facing away from the arc-shaped outer ring 3113c, and the guiding ring 3113 is sleeved on the first lifting assembly 21.

[0066] In this embodiment, a guiding ring 3113 is provided on the side of the arc-shaped inner ring 3112b facing away from the arc-shaped outer ring 3113c. The guiding ring 3113 is horizontally arranged, and the diameter of the guiding ring 3113 is smaller than the distance between the arc-shaped inner ring 3112b and the offshore monopile foundation 200. The first lifting assembly 21 is vertically arranged through the guiding ring 3113, which is beneficial to improving the transmission stability between the driving device 20 and the net cage unit 311. Among them, the guiding ring 3113 can be in transmission connection with the first lifting assembly 21 so that the first lifting assembly 21 can drive the guiding ring 3113 to drive the net cage unit 311 to move up and down. The guiding ring 3113 can also be in sliding fit with the first lifting assembly 21 to play a guiding and limiting role. At this time, the net cage unit 311 can be in transmission connection with the arc-shaped inner ring 3312b through other forms of connecting members, which is not limited here.

[0067] It should be noted that in some embodiments of the ocean ranching system 100 of the present invention, there are several first lifting assemblies 21. The several first lifting assemblies 21 are arranged in a circumferential arrangement around the offshore monopile foundation 200. There are several net cages 31, and each net cage 31 is in transmission connection with a first lifting assembly 21 to move up and down in the vertical direction under the drive of the first lifting assembly 21. The net cage 31 is composed of several net cage units 311 connected in sequence along the circumference of the offshore monopile foundation 200. At least one of the net cage units 311 is in transmission connection with the first lifting assembly 21 to realize the liftable setting of the net cage 31. In a feasible implementation manner, the guiding ring 3113 of at least one net cage unit 311 of the net cage 31 is in transmission connection with the first lifting assembly 21, and the guiding rings 3113 of the remaining net cage units 31 are in sliding fit with the remaining first lifting assemblies 21. Such a setting can prevent interference between the net cages 31 during the lifting movement.

[0068] In some embodiments of the ocean ranching system 100 where the invention is applied to the offshore monopile foundation 200, the net cage unit 311 is further provided with a cover structure, and the cover structure is openably sealed on the surface of the net cage unit 311 so that a waterproof space is formed inside the net cage unit 311.

[0069] In this embodiment, the cage unit 311 is further provided with a cover structure, which is used to seal the surface of the cage unit 311. The cover structure can be opened and closed. It can be closed on the surface of the cage unit 311 to keep the outer surface of the cage unit 311 closed, thereby forming a waterproof space inside the cage unit 311. In this way, the buoyancy of the empty cage can be used to float the cage unit 311 on the sea surface, allowing the cage unit 311 to be towed and transported on the sea surface without occupying transportation space on transportation equipment, thereby improving the transportation efficiency of the cage unit 311. The cover structure can also be opened to connect the sides of the cage unit 311, ensuring the fluidity of the water inside and outside the cage unit 311, so as to realize the marine aquaculture function of the cage unit 311.

[0070] In some embodiments, the cover structure includes a plurality of cover plates, each of which is respectively arranged around the outside of the cage unit 311. Each cover plate can be opened and closed to form a closed waterproof space when each cover plate is closed. Of course, the cover plates can also be arranged only around the side and bottom surfaces of the cage unit 311 to form a waterproof space with an open top. When the top of the cage unit 311 is floated above the sea surface, the cage unit 311 can also float on the sea surface with the help of the buoyancy of the empty box. Furthermore, to ensure the airtightness between the plurality of cover plates, a sealing structure can be provided between two adjacent cover plates. The material of the sealing structure can be, but is not limited to, rubber. By sealing the gap between the two adjacent cover plates with the sealing structure, the airtightness of the cover structure can be improved, and water can be prevented from entering the internal waterproof space when the cover structure covers the surface of the cage unit 311, causing the cage unit 311 to overturn or sink.

[0071] Specifically, in a feasible embodiment, several cover plates can be retracted and arranged, and several rolling curtain mechanisms are provided on the frame 3111 of the cage unit 311. Each rolling curtain mechanism is connected to a cover plate in a transmission manner, so that the cover plate can be extended and sealed on the surface of the cage unit 311 under the drive of the rolling curtain mechanism, or the cover plate can be retracted and wound and fixed on one side of the surface of the cage unit 311 under the drive of the rolling curtain mechanism. The specific implementation method can be set according to actual needs and is not limited here.

[0072] Please refer to Figure 1 In some embodiments of the invention, the marine ranch system 100 is applied to an offshore monopile foundation 200, and the marine ranch system 100 further includes a fixing device 40, which is located below the cage assembly 30 and is used for anchoring to the seabed, and the cage assembly 30 is detachably connected to the fixing device 40.

[0073] In this embodiment, the ocean ranching system 100 further includes a fixing device 40. The fixing device 40 is located below the cage assembly 30 and can be anchored to the seabed. The cage assembly 30 is detachably connected to the top of the fixing device 40, and a plurality of cages 31 are detachably connected in sequence in the vertical direction. Thus, the cage assembly 30 is anchored to the seabed by relying on the fixing device 40, thereby improving the structural stability of the ocean ranching system 100 and enhancing the ability of the ocean ranching system 100 to resist environmental loads. In some embodiments, the fixing device 40 can be arranged to be liftable as in the following embodiments, so as to be able to move towards the seabed and be anchored in the soil of the seabed. Among them, the fixing device 40 can be, but is not limited to, directly connected to the bottom of the cage 31 at the bottom layer of the cage assembly 30, so as to move up and down with the cage 31 at the bottom layer of the cage assembly 30 under the drive of the first lifting assembly 21, or a second lifting assembly can be arranged as in the following embodiments to drive the fixing device 40 to move up and down independently. Details are not elaborated here; of course, the fixing device 40 can also be arranged as a kind of power anchor structure and be anchored in the soil of the seabed by means of launching or free fall, etc. The specific implementation manner can be set according to actual needs.

[0074] It can be understood that with such an arrangement, when the environmental load is large due to strong winds and waves on the sea, etc., a plurality of cages 31 and the fixing device 40 can be driven to be connected in sequence to form a whole, and the whole structure can be made to dive together until the whole structure is anchored to the seabed by the fixing device 40. Thus, the ability of the whole structure to resist the regional environmental load can be improved; when the environmental load is small and normal aquaculture can be carried out, the fixing device 40 can be separated from the cage assembly 30, and a plurality of cages 31 of the cage assembly 30 can be separated in sequence and rise to corresponding depths respectively to resume full-depth seawater aquaculture.

[0079] The marine ranch system 100 further includes a vacuum pumping assembly 50. One end of the vacuum pumping assembly 50 is arranged on the platform 10, and the other end of the vacuum pumping assembly 50 communicates with the box body to generate negative pressure inside the fixing box when the bottom of the box body abuts against the seabed.

[0080] In this embodiment, the fixing device 40 is a box body with an open bottom, and the top of the box body is detachably connected to the bottommost net cage 31 of the net cage assembly 30. The marine ranch system 100 further includes a vacuum pumping assembly 50. One end of the vacuum pumping assembly 50 is arranged on the platform 10, and the other end communicates with the box body, and is used to extract the gas or liquid flow inside the box body, so as to generate negative pressure inside the fixing box, so that the box body can penetrate into the soil layer of the seabed under the action of negative pressure and its own gravity to play an anchoring role.

[0081] In some embodiments, the vacuum pumping assembly 50 can be set as an air pump 51 and a connecting pipe 52. The air pump 51 can be arranged on the platform 10, and the connecting pipe 52 can extend downward through the gap between the annular box body and the offshore monopile foundation 200 and communicate with the box body. In a feasible implementation manner, a connecting joint communicating with the internal space of the box body is arranged on the outer wall of the box body, and the connecting joint and the connecting pipe 52 are in sealing cooperation, so that the airtightness between the fixing device 40 and the vacuum pumping assembly 50 can be improved.

[0082] In a feasible implementation, a transmission structure is provided on one side of the box body facing the offshore monopile foundation 200. The transmission structure can be, but is not limited to, arranged in a ring shape for sleeving on the second lifting component to be in transmission connection with the second lifting component, so that the second lifting component can drive the transmission structure to reciprocate along its length direction, thereby driving the box body to lift; of course, the transmission structure can also be arranged in other shapes and can be directly or indirectly in transmission connection with the second lifting component. The specific implementation can be set according to actual needs and will not be limited here.

[0083] Please refer to Figure 5 , in some embodiments of the ocean ranching system 100 where the invention is applied to the offshore monopile foundation 200, the box body includes a plurality of fixed box units 41. The bottom of the fixed box unit 41 is penetrated. The plurality of fixed box units 41 are arranged in a circumferential arrangement around the offshore monopile foundation 200. Two adjacent fixed box units 41 are detachably connected. At least one of the tops of the fixed box units 41 is detachably connected to the net cage assembly 30;

[0084] A plurality of vacuum pumping assemblies 50 are provided, and each vacuum pumping assembly 50 communicates with one fixed box unit 41.

[0085] In this embodiment, the box body includes a plurality of fixed box units 41, and the bottom of the fixed box unit 41 is penetrated; the plurality of fixed box units 41 are arranged in a circumferential arrangement around the offshore monopile foundation 200. Two adjacent fixed box units 41 are detachably connected, so that the plurality of fixed box units 41 can be lifted synchronously; and at least one fixed box unit 41 is detachably connected to the net cage assembly 30, so that the fixing device 40 can be connected to the bottom of the bottommost net cage 31 of the net cage assembly 30.

[0086] Furthermore, a plurality of vacuum pumping assemblies 50 are provided, and each vacuum pumping assembly 50 communicates with one fixed box unit 41 to enable each fixed box unit 41 to independently realize the anchoring function; with such a setting, by synchronously pumping vacuum for a plurality of fixed box units 41 through a plurality of vacuum pumping assemblies 50, the efficiency of the vacuum pumping step can be improved; and since each fixed box unit 41 can independently realize the anchoring function, even in the case where some fixed box units 41 are damaged or malfunction, the fixing device 40 can still realize the anchoring function of the fixing device 40 by virtue of the coordinated action of the remaining normally operating fixed box units 41.

[0087] In some embodiments of the ocean ranching system 100 where the invention is applied to the offshore monopile foundation 200, the ocean ranching system 100 further includes a rotating mechanism. The rotating mechanism is arranged on the platform 10 for driving the platform 10 to rotate around the offshore monopile foundation 200 to drive the driving device 20 and the net cage assembly 30 to rotate around the offshore monopile foundation 200.

[0088] In this embodiment, the offshore ranching system 100 further includes a rotating mechanism. The rotating mechanism is disposed on the platform 10 and is used to drive the platform 10 to rotate around the offshore monopile foundation 200, so as to drive the driving device 20 and the net cage assembly 30 to rotate around the offshore monopile foundation 200 accordingly. Among them, the rotating mechanism can be, but is not limited to, set as a rotating motor. The rotating motor is disposed on the offshore monopile foundation 200, and the platform 10 is in transmission connection with the rotating motor.

[0089] It should be noted that since the net cage assembly 30 is usually immersed in water for a long time, aquatic organisms will slowly adhere to the net of the net cage assembly 30. In the long run, there is a risk of blocking the mesh holes of the net and reducing the water flow rate inside the space of the net cage assembly 30. On the one hand, it will cause the oxygen content in the water body inside the net cage assembly 30 to decrease, affecting the aquaculture effect. On the other hand, it will affect the service life of the net. In the existing related technologies, it is often necessary to manually clean the net attached with aquatic organisms regularly, with low cleaning efficiency and high cleaning cost.

[0090] Therefore, it can be understood that the technical solution of the present invention, by setting the rotating mechanism, can drive the platform 10 to rotate around the offshore monopile foundation 200 at a certain speed, so as to drive the net cage assembly 30 to rotate synchronously around the offshore monopile foundation 200, thereby being able to use the seawater to oscillate and impact the net of the net cage assembly 30, thus playing a role in cleaning the net, reducing the risk of aquatic organisms blocking the mesh holes of the net, being beneficial to ensuring the aquaculture effect, and prolonging the service life of the net cage assembly 30.

[0091] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural transformations made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
