Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] See Figure 1 This embodiment describes a multifunctional offshore aquaculture platform, comprising a central building 1, a net cage aquaculture system, and a base. The base is located on the seabed, and both the central building 1 and the net cage aquaculture system are mounted on the base. Multiple net cage aquaculture systems are arranged circumferentially around the central building 1. A fish transfer channel is located beneath the central building 1, and the multiple net cage aquaculture systems are connected via the fish transfer channel. Each net cage aquaculture system includes a net cage frame 2 and a net 3. A deck is provided on the upper part of the cage frame 2. A net hanging mechanism is provided on the cage frame 2. The net 3 is placed inside the cage frame 2. The net 3 is vertically woven with net reinforcing ropes 15. One end of the net reinforcing ropes 15 is connected to the net hanging mechanism, and the other end is connected to the bottom of the net 3. A gate track 17 is provided on the cage frame 2. A lifting gate 16 is provided at the fish transfer channel. The lifting gate 16 is connected to the gate track 17. A fish-driving net plate is movably connected inside the fish transfer channel.

[0026] The fish transfer channel includes strip channels 13 and annular channels 14. The number of strip channels 13 is the same as the number of net cage aquaculture systems. One end of each strip channel 13 is connected to a corresponding net cage aquaculture system, and the other end is connected to the annular channel 14. A strip channel fish-driving net plate 19 is installed inside each strip channel 13. A pulley 20 is installed on the upper part of the strip channel fish-driving net plate 19, and the pulley 20 is connected to a motor. A straight track 21 is installed at the top of each strip channel 13, and the pulley 20 is connected to the straight track 21. An annular channel fish-driving net plate 23 is installed inside each annular channel 14. A supporting pulley is installed at the lower part of the annular channel fish-driving net plate 23. The pulley is connected to the motor. A circular track 24 is provided at the bottom of the annular channel 14. The supporting pulley is connected to the circular track 24. A push-pull gate 18 is provided at the connection between the strip channel 13 and the annular channel 14. Steel cables 22 are provided on both sides of the middle of the strip channel fish-driving net plate 19. The raising and lowering of the strip channel fish-driving net plate 19 is controlled by tightening and loosening the steel cables 22. There are four net cage aquaculture systems. The net cage frame 2 is a hexagonal prism structure. The net cage aquaculture system is equipped with supporting aquaculture devices, including feeding equipment, underwater monitoring equipment, net washing equipment, dead fish catching equipment, underwater robot, lighting equipment and / or sound equipment.

[0027] Reference Figure 3-4The net cage aquaculture system consists of four net cage frames 2, constructed from high-strength cylindrical steel welded into a hexagonal prism shape, with a welded deck on top for personnel movement. Each net cage frame 2 has a net hanging mechanism that can raise or lower the net 3 according to water depth, controlling the fish's movement range and harvesting mature fish. The net consists of two parts: one is a liftable net 3 suspended on the net cage frame, primarily made of high-strength materials such as polyethylene or nylon. Vertically woven net reinforcing ropes 15 connect one end to the upper net hanging mechanism of the net cage and the other end to the bottom of the net 3. Raising and lowering the net 3 is achieved by raising and lowering the reinforcing ropes 15, thus enclosing the main aquaculture water body. The other part is a liftable gate 16 corresponding to the opening of the fish transfer channel. This gate is constructed by fixing the net to the gate frame on all four sides and suspending it from the net cage frame 2 via hooks and ropes. The gate frame is made of stainless steel, and the net is primarily made of high-strength materials such as polyethylene, metal wire, or nylon. The cage frame 2 has a gate track 17 that restricts the direction of gate movement, allowing the lifting gate 16 to slide smoothly up and down. The supporting aquaculture equipment includes feeding, underwater monitoring, net washing, and dead fish removal devices. Underwater robots or nets of different mesh sizes are used, along with methods such as lighting, sound, water flow, and food, to guide or drive the fish, encouraging movement, reducing disease rates, and improving fish quality. The fish transfer channel is located below the central building, connecting four cage aquaculture systems. If the netting of one cage is damaged, the fish can be transferred to other cages through the transfer channel. The channel entrance has a lifting gate 16 that can move up and down. Sliding fish-driving nets are installed inside the transfer channel to drive the fish within the channel and control their transfer to other cages, enabling timely repair of damaged cages and the separate cultivation and harvesting of fish of different sizes in different cages.

[0028] Reference Figure 3-8 This describes the process of transferring fish from one net cage space to another. The fish transfer channel consists of four strip channels 13 and one ring channel 14. One end of the strip channels 13 is connected to the aquaculture net cage, and the other end is connected to the ring channel 14. Each strip channel is equipped with a strip channel fish-driving net plate 19. The overall size of the strip channel fish-driving net plate 19 is slightly smaller than the cross-section of the strip channel 13, and it is made by fixing the netting to a steel frame. The upper part of the strip channel fish-driving net plate 19 is equipped with a motor and pulleys 20, and the top of the channel is equipped with a straight track 21, in which the pulleys 20 can move. The middle position of the net plate and points a and b on the upper part of the net plate are connected by steel cables 22. The two steel cables 22 can be tightened and loosened to control the raising and lowering of the net plate. The motor drives the pulleys 20 to move between points A and C in the strip channel.

[0029] The working steps of the strip channel fish-driving net plate 19 are as follows:

[0030] Step S1: After the strip channel fish-driving net panel 19 is lowered, it can be raised to both sides a and b. When the steel cable 22 at end b is loosened and the steel cable 22 at end a is tightened, the net panel rotates and rises towards side a; when the steel cable 22 at end a is loosened and the steel cable 22 at end b is tightened, the net panel can rotate and rise towards side b.

[0031] Step S2: After the strip channel fish-driving net plate 19 is raised, loosen one end of the steel cable 22, tighten the other end of the steel cable 22, rotate and lower the net plate, then maintain the length of the two steel cables 22, start the motor, and the motor drives the pulley 20 to move back and forth along the straight track 21, as shown. Figure 5 .

[0032] The annular channel is equipped with a fish-repelling net 23, similar to the strip channel fish-repelling net 19. The lower part of this net is equipped with supporting pulleys, ensuring it remains upright and moves in a circular motion along the circular track 24 at the bottom of the channel. A sliding gate 18 is located at the junction of the strip channel 13 and the annular channel 14, switching between points D and E to block fish. Figure 6 As shown.

[0033] When the fish are transferred from cage ① to cage ③, the following steps are taken:

[0034] Step S1: Adjust the height of the bottom of the netting in cage ① to the entrance of the strip channel. Raise the corresponding gates for cages ① and ③, while keeping the corresponding gates for cages ② and ④ closed. Raise the net panels inside strip channels ① and ③. Move the net panel inside strip channel ② to point B2, move the net panel inside strip channel ④ to point B4, and move the net panel in the circular channel to point E1. Push the net panel at point D3 to point E3, thus constructing a fish transfer channel from cage ① to cage ③. Figure 7 .

[0035] Step S2: Use underwater robots or seine nets of different mesh sizes, along with methods such as lights, sounds, water flow, and food, to guide or drive the fish into the channel.

[0036] Step S3: After herding the fish from cage ① into the channel, lower the corresponding gate for cage ①. Lower the net panel at point A1 in the first strip channel, and move the net panel along the straight track from point A1 to point B1. Move the net panel in the circular channel counter-clockwise along the track from point E1 to point F3. Lower the net panel at point C3 in the third strip channel, and move the net panel along the straight track from point C3 to point A3. Lower the gate for cage ③. At this point, all the fish have been transferred from cage ① to cage ③.

[0037] The base is a reinforced concrete base 9 and / or a steel frame base 10. The base has two structural types: reinforced concrete base 9 and steel frame base 10, or it can be manufactured by combining the two types. It can be constructed according to local geographical conditions to determine the height and structural type, so that the platform can be adapted to installation and operation in most shallow and medium water geographical conditions.

[0038] The central complex 1 includes a surface section and an underwater section. The surface section is equipped with facilities such as aquaculture cage management rooms, a hotel, and / or indoor leisure and entertainment facilities.

[0039] The underwater section is equipped with an underwater hotel, an underwater viewing platform 8, and / or an aquaculture monitoring system. A double-layered tempered glass curtain wall allows visitors to directly view the underwater world, while aquaculture managers can monitor fish growth and activity. A marine park 11 is located around the central building 1, featuring a bathing area, diving pool, fishing spots, and other recreational facilities. The central building 1 and the cage frame 2 are equipped with berthing points, wind turbines 4, cranes 5, a helipad 6, a control room 7, storage rooms, water treatment equipment, and / or solar panels. The helipad 6 can be located on the roof of the central building 1. The berthing points provide docking stations for transport ships 12 and yachts for transporting personnel and supplies. The wind turbines 4, cranes 5, control room 7, storage rooms, water treatment equipment, and solar panels provide the platform with production support including supplies, electricity, and hydrological and meteorological information.

[0040] In summary, the aquaculture platform described in this invention utilizes multiple methods to drive fish schools, enabling them to move between different net cages. This allows for timely repair of damaged net cages and the separate cultivation and harvesting of fish of different sizes in different net cages. The platform combines multiple functions, including aquaculture production, leisure and entertainment, and water quality and meteorological monitoring. It can operate profitably in the long term, has high space utilization, a safe and reliable structure, low requirements for geographical conditions in the construction area, diverse functions, and high overall economic benefits.

[0041] The above provides a detailed description of a multifunctional marine aquaculture platform provided by the present invention. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
