DETAILED DESCRIPTION

[0020] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0021] In the present disclosure, unless otherwise stated, directional words such as "upper" and "lower" are defined for the layout direction of the aquaculture system when it is actually used, and directional words such as "inner" and "outer" are defined for the outline of the corresponding components. The use of terms such as "first" and "second" is intended to distinguish different components and does not have order and importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements.

[0022] According to one embodiment of the present disclosure, Figures 1 to 4As shown, a breeding system is provided, including a breeding cage 1, a wind turbine 2, an operating platform 3, a battery and a feeding assembly 4. A holding space 10 for holding seafood is formed inside the breeding cage 1, and the breeding cage includes a buoyancy column 11 for holding liquid, and the buoyancy column 11 can be connected to the outside in an openable and closable manner so as to move in the height direction by changing the overall weight. The wind turbine 2 can be arranged above the buoyancy column 11, and the operating platform 3 can be arranged above the breeding cage 1. The battery can be arranged on the operating platform 3 and electrically connected to the wind turbine 2, and is used to convert the wind energy provided by the wind turbine 2 into electrical energy. The feeding assembly 4 is arranged on the operating platform 3, and is used to feed bait into the breeding cage 1. Here, the wind turbine 2 can adopt a 4-megawatt wind turbine, the diameter of the three propellers can be 130 meters, the height of the wind turbine 2 can be 24 meters, the diameter range is 12 meters-14 meters, the diameter of the heave tank is 28 meters, the height is 2.5 meters, the designed draft is 14 meters, and the freeboard is 10 meters. The wind turbine 2 can also use generators of other specifications and sizes, and the present disclosure does not limit this.

[0023] Through the above technical solution, the aquaculture system includes an aquaculture cage 1 and a wind turbine 2 arranged on a buoyancy column 11. The aquaculture cage 1 is used as the base of the wind turbine 2, which can not only solve the problem of high cost caused by the large foundation volume of the deep-sea wind turbine 2. At the same time, an operating platform 3 is arranged on the aquaculture cage 1, and the wind turbine 2 can convert wind energy into electric energy and store it in a battery arranged on the operating platform 3, so as to directly transmit the electricity generated by offshore wind power to the relevant control structure of the aquaculture cage 1, so as to achieve self-sufficiency in power supply, shorten the distance of power transmission, reduce the cost of power transmission, and realize the economic benefits of offshore aquaculture. At the same time, due to sufficient power supply, a feeding component 4 is arranged on the operating platform 3, and the feeding component 4 is powered by a battery to facilitate automatic aquaculture feeding, save feeding time and labor costs, and save time and effort.

[0024] It should be noted that the feeding assembly 4 and the buoyancy column 11 can have their own control functions and be powered by batteries. The operator only needs to operate the corresponding buttons on the feeding assembly 4 and the buoyancy column 11 to complete the control of the water inlet and outlet of the buoyancy column 11 or the feeding of the feeding assembly 4. The operating platform 3 can also be provided with an overall control system connected to the breeding cage 1, the wind turbine 2 and the feeding assembly 4. The remote control can be performed by directly operating the control system on the operating platform 3 or by setting a remote control center on land to wirelessly connect to the control system. The present disclosure does not limit this. For example, in the scheme of setting a remote control center on land, the feeding assembly 4 can be controlled by intelligent software, which can realize remote feeding and automatic feeding. The software can record parameters such as feeding time, feeding duration, feeding amount, and remaining bait, so that managers can better analyze the growth status of fish and control feeding costs.

[0025] In addition, other breeding equipment 6 may also be provided on the operating platform 3 and connected to the control system to realize other functions, such as environmental monitoring related equipment, underwater biological identification related equipment, fish gathering light related equipment, radar equipment and net cleaning robot related equipment, etc., which are not limited in the present disclosure.

[0026] Specifically, the environmental monitoring related equipment can be based on the marine Internet of Things technology, and can monitor the surface weather in the area where the aquaculture cage 1 is placed, various water quality parameters in the aquaculture waters, underwater high-definition video and hydrological parameters such as flow rate, flow direction, wave height, and wave period in real time online. The related equipment for underwater biological identification can be used for overall monitoring of the number of farmed seafood in the aquaculture cage 1, dynamic monitoring of farmed fish schools, identification of seafood species, accurate size calculation of farmed seafood, and weight distribution statistics. The fish-gathering lamp related equipment can be based on the phototaxis characteristics of seafood. The light source can attract a large number of plankton and small fish and shrimp near the aquaculture cage 1 into the containing space 10, which is convenient for the seafood population inside the aquaculture cage 1 to prey, thereby increasing the predation and feeding time of seafood, accelerating the growth rate, and shortening the growth cycle of seafood. The radar equipment can automatically track and detect dynamic targets at sea within the coverage range, and record data information such as the position, heading and speed of dynamic targets, and produce historical image information. The medium-load or heavy-load pan / tilt is equipped with a long-view optical camera and an infrared camera that can be used in conjunction with it to collect video of the guarded sea area in real time. The equipment related to the net inspection robot is a supporting equipment designed for large net cages. The net cleaning robot can also integrate acoustic positioning communication equipment, underwater intelligent image recognition function, inertial navigation and carry underwater cleaning components. It can not only confirm the status of underwater nets, but users can also use the net inspection robot to promptly detect net damage to avoid or reduce economic losses. At the same time, it can also prevent the continued growth of marine organisms attached to the nets by cleaning the nets mentioned below, and reduce the impact of biological attachment on the nets and organisms in the aquaculture cages 1.

[0027] Furthermore, if Figures 1 to 3As shown, the aquaculture cage 1 may include a first net 13, a second net 14 and two frames 12 arranged opposite to each other. The two frames 12 may be connected to the two ends of the height direction of the buoyancy column 11, respectively. The first net 13 may be laid on the frame 12 at the bottom of the buoyancy column 11, and the second net 14 may be arranged between the two frames 12. The first net 13 and the second net 14 enclose a receiving space 10. The net is light in weight, which makes it easier to adjust the ballast water of the buoyancy column 11 to float or sink. In addition, the porous net also facilitates nearby plankton and small fish and shrimp to enter the receiving space 10, which is convenient for the marine product population inside the aquaculture cage 1 to prey on, thereby increasing the time for marine product predation and feeding, accelerating the growth rate, and shortening the growth cycle of marine products. In addition, reinforcing ribs 16 may be arranged between the two frames 12 to increase the structural strength of the aquaculture cage 1. The number of reinforcing ribs 16 may be determined according to actual needs, and the present disclosure does not limit this. A movable net window can also be set near the waterline of the breeding net cage 1 as a live fish inlet and outlet, and the movable net window can be opened on the second net 14, and the movable net window can be used to connect to an external live fish delivery ship to achieve the delivery of fry and adult fish. Here, the live fish delivery system can be composed of a vacuum tank, a vacuum water ring pump, a pressure water ring pump, a water ring pump cooling pump, a fish-water separator, an air compressor, an air bottle, a control device and related valve accessories.

[0028] Furthermore, if Figure 1As shown, the second net 14 may include an inner net 141 and an outer net 142 which are arranged at intervals, the two ends of the inner net 141 are respectively connected to the two frames 12 and enclosed with the first net 13 to form a receiving space 10, the top of the outer net 142 is connected to the frame 12 at the top of the buoyancy column 11, and the bottom of the outer net 142 is spaced from the frame 12 at the bottom of the buoyancy column 11. The inner net 141 is used to enclose and form a receiving space 10 for breeding seafood, and the outer net 142 is spaced from the inner net 141 mainly to intercept floating objects and prevent other fish from attacking the breeding fish. At the same time, in order to prevent seafood from escaping while taking into account the cost of the net, the mesh number of the outer net 142 can be smaller than the mesh number of the inner net 141. Specifically, the mesh number of the inner net 141, the first net 13 and the third net 15 mentioned below can all be 55 mm, with a wire diameter of 2.5 mm. The mesh length of the outer net 142 can be 100 mm, and the present disclosure does not limit this. With respect to the spatial shape formed by the inner net 141 and the outer net 142, the frame 12 may include a triangular outer frame formed by overlapping three outer beams, and three inner beams are connected between two adjacent outer beams, so that the inner beams and part of the outer beams together form a regular hexagonal inner frame. In this way, the outer net 142 can form a triangular prism space, and the inner net 141 can form a hexagonal prism space. The hexagonal side length of the hexagonal prism-shaped accommodation space 10 formed by the inner net 141 can be 20m, and the volume can be between 11000m3-12000m3. In addition, the top of the inner net 141 is suspended on the upper frame 12 by a cantilever tooling, and the bottom is connected to the lower frame 12 by a fixed pulley guide, which is convenient for replacing the net. A rope can also be laid on the frame 12 to connect with the inner net 141 to facilitate the installation and lifting of the inner net 141. The portion of the inner net 141 that is usually exposed above the water surface may also be made of a different material from the underwater portion to reduce procurement costs. The range that is usually exposed above the water surface may be determined in combination with the platform motion performance analysis data, and the present disclosure does not limit this.

[0029] Furthermore, if Figure 1 and Figure 3 As shown, the aquaculture cage 1 may also include a third net 15, which may be connected to the frame 12 at the top of the buoyancy column 11 and cover the top of the inner net 141, so that the third net 15 constitutes the top net of the accommodating space 10 to prevent birds from flying above the aquaculture cage 1 to steal the farmed seafood. The upper part of the third net 15 may also be provided with an openable and closable opening, which may be used for leisure fishing and increase the economic benefits of aquaculture. The first net 13, the second net 14 and the third net 15 may all be made of ultra-high molecular weight polyethylene, or other plastic materials with high strength and light weight, which is not limited in the present disclosure.

[0030] According to one embodiment of the present disclosure, Figure 4As shown, the feeding assembly 4 may include a bait tank 41, a feed channel 42, a feeder 43 and a fan 44. The bait tank 41 may be arranged on the operating platform 3, and the feed channel 42 may be connected to the bottom of the bait tank 41, and pass through the operating platform 3 to communicate with the accommodation space 10. The feeder 43 may be connected to the connection between the feed channel 42 and the bait tank 41 in an openable and closable manner, and may control the connection between the bait tank 41 and the feed channel 42. The fan 44 is connected to the feed channel 42, and is used to provide a thrust to the bait in the feed channel 42 away from the feed channel 42. Feeding is achieved by controlling the opening and closing of the bait tank 41 through the feeder 43, and then the fan 44 provides an airflow to blow the bait in the feed channel 42 out of the mass accommodation space 10 for feeding. Here, the blower 44 may be a Roots blower, and one end of the feed channel 42 away from the bait tank 41 is connected to a distributor, and a plurality of nozzles are connected to the distributor to increase the range of bait throwing, thereby improving the feeding effect.

[0031] According to one embodiment of the present disclosure, Figures 1 to 3 As shown, the buoyancy column 11 may include a damping cabin 111 and a column 112. The damping cabin 111 may be used to contain liquid, the column 112 may be connected above the damping cabin 111, and the wind turbine 2 is arranged on the column 112. When liquid is injected into the damping cabin 111, the density of the buoyancy column 11 increases, which can drive the aquaculture cage 1 to sink as a whole. When the damping cabin 111 discharges liquid outward, the density of the buoyancy column 11 decreases, which can drive the aquaculture cage 1 to float. The damping cabin 111 for drainage and absorption is arranged at the bottom of the buoyancy column 11, which can not only improve the stability of the aquaculture cage 1, but also effectively increase the distance that the aquaculture cage 1 moves up and down. In addition, an empty cabin may also be arranged inside the column 112 for storing tools, feed for fishery breeding and other items to improve the space utilization rate of the aquaculture cage 1. Regarding the shape of the column 112 , the column 112 may be cylindrical, or the column 112 may be composed of an inverted cone portion and a cylindrical portion connected to the bottom of the inverted cone portion, and the lower portion of the cylindrical portion may be connected to the damping cabin 111 .

[0032] Furthermore, if Figures 1 to 3 As shown, the area of ​​the damping cabin 111 on the side close to the column 112 is larger than the area of ​​the column 112 on the side close to the damping cabin 111. The damping cabin 111 at the bottom has a large area, which can effectively increase the contact area with the sea surface when the buoyancy column 11 is in the rising state, and can also increase the contact area with the seabed after the buoyancy column 11 is lowered, which can not only improve the stability of the placement of the wind turbine 2, but also improve the stability of the placement of the aquaculture cage 1 itself.

[0033] Specifically, Figures 1 to 3As shown, the buoyancy column 11 can be set at the edge of the aquaculture cage 1, and there are multiple buoyancy columns 11 set at intervals. The spacing between adjacent buoyancy columns 11 can be 70m-80m, and the wind turbine 2 is set above one of the buoyancy columns 11. The accommodating space 10 is located within the space formed by multiple buoyancy columns 11, which can make the overall motion coupling of the aquaculture cage 1 simple and the design risk more controllable. Taking the example of three buoyancy columns 11 arranged in a triangular and evenly spaced arrangement, the wind turbine 2 is offset at this time. The draft, center of gravity and inclination of the entire structure can be adjusted by adjusting the mass of the ballast water inside different buoyancy columns 11 to ensure the stability of the entire device. In the working state, setting appropriate ballast water can lower the center of gravity of the entire device and improve the overall stability of the aquaculture cage 1.

[0034] According to one embodiment of the present disclosure, Figures 1 to 3 As shown, the aquaculture system may further include a crane 5 for fishing the seafood inside the accommodation space 10. The crane 5 is arranged above the aquaculture cage 1, so as to operate the crane 5 to fish the cultivated seafood when needed, or to fish out the dead seafood when there are dead seafood in the accommodation space 10 to prevent other seafood from being affected. The number of cranes 5 can be multiple and they are arranged at intervals on the aquaculture cage 1, and the present disclosure does not limit this.

Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0036] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0037] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
