[0024] Example 1 An ocean ranching device, which includes multiple aquaculture units spliced together. The adjacent aquaculture units are fixedly connected by a connecting component. Splicing multiple aquaculture units together forms an aquaculture scale, which is conducive to management and energy utilization. The connecting component includes a locking plate 18, a locking block 17, and a limiting block 19. The locking plate 18 is provided with a locking groove 22. The aquaculture unit includes a buoyancy platform 1, a net cage 6, and a pile foundation 7. The buoyancy platform 1 is composed of corrosion-resistant titanium alloy and high molecular composite material, and is filled with closed-cell foam inside to provide buoyancy and reduce the structural weight.

[0025] The locking plate 18 is located in one of the aquaculture units, and the locking block 17 and the limiting block 19 are located in another aquaculture unit. The locking block 17 and the locking plate 18 are respectively located on adjacent aquaculture units, and the adjacent aquaculture units are fixedly connected by the locking block 17 and the locking plate 18. The locking plate 18 and the locking block 17 cooperate with each other to lock the adjacent aquaculture units. The locking plate 18 is located at the edge of the buoyancy platform 1. One end of the locking plate 18 is fixedly connected to the buoyancy platform 1, and the other end extends to the outside of the buoyancy platform 1. At least one locking plate 18 is provided at the edge of one buoyancy platform 1, and at least one locking plate 18 is provided at at least one edge of the buoyancy platform 1. The locking block 17 is located at the edge of the buoyancy platform 1 and is adapted to the locking plate 18 of the adjacent buoyancy platform 1. The top of the locking plate 18 extends to the edge of the adjacent buoyancy platform 1 to cooperate with the locking block 17, and the locking block 17 is located in the locking groove 22. The locking block 17 is located on the buoyancy platform 1 adjacent to the locking plate 18, and at least one locking block 17 and one limiting block 19 are provided at the edge of one buoyancy platform 1, and at least one locking block 17 and one limiting block 19 are provided at at least one edge of the buoyancy platform 1. The setting of the locking block 17 and the locking plate 18 on the buoyancy platform 1 is related to the splicing position of the buoyancy platform 1. The shape of the buoyancy platform 1 can be selected as a regular triangle, square, rectangle, regular hexagon and other polygons, which is convenient for splicing into an overall plane.

[0026] The locking block 17 is rotatably connected to the buoyancy platform 1. The locking block 17 includes a vertical portion 21 and an inclined portion 20. The limiting block 19 is located inside the locking block 17, and when the vertical portion 21 is in a vertical state, the side of the limiting block 19 abuts against the vertical portion 21. The locking block 17 can rotate in a direction away from the limiting block 19.

[0027] The top of the vertical portion 21 is obliquely connected to the bottom of the inclined portion 20. A counterweight 16 is provided at the bottom of the vertical portion 21. The top of the inclined portion 20 is arc-shaped. The arc-shaped setting facilitates the clamping of the locking block 17 with the locking groove 22, reduces the sharp corners and avoids the locking plate 18 being stuck by the sharp corners of the locking block 17 when moving. The shape of the locking groove 22 fits the inclined portion 20, which is convenient for the locking block 17 to be clamped in the locking groove 22.

[0028] When two adjacent buoyancy platforms 1 need to be spliced, move the buoyancy platform 1 with the locking plate 18 towards the buoyancy platform 1 with the locking block 17. Before moving, the locking plate 18 should be aligned with the locking block 17, and ensure that the locking block 17 can be installed into the locking groove 22. When the buoyancy platform 1 is in an unused state, under the action of the counterweight 16 on the vertical part 21, the locking block 17 rotates downward, and the side wall of the limiting block 19 abuts against one side of the locking block 17, keeping the vertical part 21 in a vertical state and the inclined part 20 in an inclined state obliquely upward. When the locking plate 18 moves until the top of the locking plate 18 contacts the top of the inclined plate, the locking plate 18 pushes towards the locking block 17, the locking block 17 rotates, the inclined part 20 gradually becomes horizontal, the vertical part 21 gradually moves away from the limiting block 19 and becomes inclined until the inclined part 20 of the locking block 17 rotates into the locking groove 22. At this time, the inclined part 20 returns to the inclined setting, the vertical part 21 is vertically arranged under the action of the counterweight 16, and one side of the limiting block 19 abuts against the vertical part 21 to keep the vertical part 21 vertical. At this time, the splicing of adjacent buoyancy platforms 1 is completed. By setting the locking plate 18 and the locking block 17, and the locking block 17 is rotatably connected to the buoyancy platform 1, it supports the rapid splicing of multiple aquaculture units to form a large-scale ranch, making the splicing structure between the aquaculture units simple, the splicing operation convenient, and simplifying the installation process of the aquaculture units.

[0029] The bottom of the buoyancy platform 1 is provided with uniformly distributed pile foundations 7 along the circumferential direction. The bottom of the pile foundation 7 can hang porous concrete reefs (not shown in the figure) to promote the growth of microbial communities and form a small ecosystem. There is a net cage 6 between the pile foundations 7. The two sides of the net cage 6 are slidably connected to the pile foundation 7. Control components 2 for controlling the up and down movement of the net cage 6 are provided at both ends of the top of the buoyancy platform 1. The control components 2 at both ends include motors 15, screws 10, moving rods 13, sleeve one 8, and sleeve two 9. Control components 2 are provided at both ends of the buoyancy platform 1. Motors 15 are provided at both ends of the buoyancy platform 1. The motors 15 on both sides are synchronous motors 15, which can control the start and stop of the motors 15 on both sides simultaneously. The electrical connection and control principle of the motors 15 adopt existing technologies.

[0030] The first sleeve 8 is located on the buoyancy platform 1. Second sleeves 9 are provided on both sides of the first sleeve 8. One end of the moving rod 13 penetrates through the second sleeve 9 and extends to the bottom of the buoyancy platform 1 and is fixedly connected to the top of the fish cage 6. The moving rod 13 is slidably connected to the second sleeve 9. One end of the screw rod 10 is located inside the first sleeve 8. A thread groove is provided on the inner wall surface of the first sleeve 8, and the thread groove is matched with the thread of the screw rod 10. A cross beam 14 is provided between the moving rods 13 at both ends. The top of the screw rod 10 is rotatably connected to the cross beam 14. The buoyancy platform 1 is provided with a perforation for the movement of the moving rod 13. A first bevel gear 11 is provided on the output end of the motor 15. A second bevel gear 12 meshing with the first bevel gear 11 is sleeved on the screw rod 10. A wave energy power generation assembly 5 is provided on the side wall surface of the pile foundation 7. The wave energy power generation assembly 5 is electrically connected to the control assembly 2. The wave energy power generation assembly 5 belongs to the prior art and is arranged around the deep-sea fish cage 6 to provide a power source for the lifting of the deep-sea fish cage 6.

[0031] A fish cage 6 is provided at the bottom of each breeding unit. Different economic marine organisms can be bred inside different fish cages 6. The first sleeve 8 is sleeved on the outside of one end of the screw rod 10. The screw rod 10 can rotate in the first sleeve 8 through the thread groove in the first sleeve 8 for up and down movement. The rotation of the motor 15 drives the first transfer gear to rotate. The rotation of the first bevel gear 11 drives the second bevel gear 12 to rotate, thereby driving the screw rod 10 to rotate in the first sleeve 8. The screw rod 10 rotates for up and down movement, thereby driving the moving rods 13 on both sides to move up and down in the second sleeve 9, thereby driving the fish cage 6 to move up and down. The motors 15 of the control assemblies 2 on both sides of the buoyancy platform 1 start and stop simultaneously to drive the two ends of the fish cage 6 to move up and down simultaneously, thereby realizing the overall up and down movement of the fish cage 6.

[0032] By providing a liftable fish cage 6, when the sea surface is windy and wavy, to avoid the fish cage 6 being overturned by the wind and waves, the fish cage 6 can be moved down to a deeper sea surface through the control assembly 2 of the buoyancy platform 1, avoiding the marine organisms such as fish in the fish cage 6 from fainting and suffocating due to mutual collision when the wind and waves are large. By providing the control assembly 2 on the buoyancy platform 1, the fish cage 6 can be moved up and down through the cooperation of the motor 15, the screw rod 10 and the gears, avoiding the fish cage 6 being overturned by excessive wind and waves and improving the wave resistance ability of the breeding unit.

[0033] Sliders 4 are provided on both sides at both ends of the fish cage 6. Corresponding chutes 3 are provided on the side wall surface of the pile foundation 7. The sliders 4 slide in the chutes 3. When the fish cage 6 moves up and down through the control assembly 2, the sliders 4 slide in the chutes 3. The chutes 3 are vertically arranged on the side wall surface of the pile foundation 7, facilitating the sliders 4 to drive the fish cage 6 to perform vertical movement. By providing the chutes 3 on the pile foundation 7 in sliding contact with the sliders 4 on both sides of the fish cage 6, the fish cage 6 is kept moving vertically during the up and down movement, which is beneficial to the up and down movement of the moving rod 13 and avoids the fish cage 6 being damaged to the control assembly 2 due to the fact that the fish cage 6 cannot maintain vertical movement due to the buoyancy of seawater during the up and down movement.

[0034] Transport the ocean ranch components to the target sea area by a semi-submersible ship. First, fix the bottom pile foundation 7 of the first breeding unit to the seabed. According to the preset breeding scale of the ocean ranch, splice other breeding units and fix the pile foundations 7 of other breeding units to the seabed. Release the economically valuable marine organisms to be cultivated into the net cage 6 of the fixed ocean ranch. According to the monitored wind and wave changes, move the corresponding net cage 6 to a deeper position in the sea surface through the control component 2 to avoid the net cage 6 being overturned by excessive wind and waves near the sea surface, causing losses. When the wind and waves decrease or return to the normal level, move the net cage 6 upward to a suitable breeding position through the control component 2 again.

[0035] Therefore, the present invention adopts the above-mentioned ocean ranch device. By setting the locking plate and the locking block, and the locking block is rotatably connected to the buoyancy platform, the splicing structure between the breeding units is simple, the splicing operation is convenient, and the installation process of the breeding units is simplified; by arranging a sliding groove on the pile foundation and slidingly contacting the sliding blocks on both sides of the net cage, the net cage maintains vertical movement during the up and down movement, which is beneficial to the up and down movement of the moving rod, and avoids the net cage being damaged to the control component due to the buoyancy of seawater during the up and down movement of the net cage and being unable to maintain vertical movement; by arranging a control component on the buoyancy platform, the net cage can move up and down through the cooperation of the motor, the screw rod and the gear, avoiding the net cage being overturned by excessive wind and waves, and improving the anti-wind and wave ability of the breeding unit.
