[0002] Offshore aquaculture platforms are an advanced aquaculture facility in modern marine fisheries, mainly used to cultivate aquatic organisms such as fish and shellfish in open waters. Offshore aquaculture platforms use large cages or closed systems to increase aquaculture density and production efficiency, achieving the goal of efficient aquaculture. Therefore, offshore aquaculture has been widely used.

[0003] The existing patent CN202211292052.1 discloses a marine ranch farming system and method based on offshore wind power. The system includes a wind turbine generator set, and the marine ranch farming system also includes a cofferdam built along the coastline and located inside the wind turbine generator set. A number of water inlet pipes and water outlet pipes are laid on the cofferdam body. The marine ranch farming system also includes a number of water exchange treatment systems arranged on the first cofferdam body, and the water exchange treatment system includes a solid heat storage device, and the water inlet pipe is connected to the solid heat storage device; the solid heat storage device is connected to the wind turbine generator set through a power transmission network, and is used to convert wind power into heat energy to increase the temperature of seawater in the water inlet pipe. The present invention can directly use the electric energy of the offshore wind turbine set as an energy source for regulating the water temperature of marine ranch farming, improve the utilization rate of wind power, and reduce the consumption of industrial electricity in the ranch, thereby reducing costs. In the above patent, the marine ranch can only be established near the coastline due to the limitation of wind power generation, which limits the deep-sea farming of the marine ranch.

The lifting component includes a transmission component for providing lifting power, and a transmission plate movably installed on the main frame to move up and down with the transmission component. The breeding box includes a frame, a cylinder installed on the frame, a telescopic component installed on one end of the frame and on the other end of the cylinder push rod, and a cage installed on the telescopic component and located in the frame. The present invention is specifically for marine ranches. The device is safe and reliable and can withstand severe weather such as typhoons.

[0060] The aquaculture method based on the above-mentioned lifting deep-sea aquaculture platform comprises the following steps:

Use a tugboat to tow the aquaculture platform to the aquaculture operation sea area. The buoyancy required by the aquaculture platform is provided by the wave energy float 4. The towing state of the aquaculture platform is as follows: Figure 1 shown.

[0062] S2, the pile legs 31 are lowered by the lifting assembly to complete the pile insertion. The net box 2 is driven down along the pile legs 31 by the lifting assembly, and the net box 2 is lowered until the top of the net box 2 is flush with the box cover 5, and the box cover 5 and the net box 2 form a closed breeding area.

[0063] S3, push pulley 55 to slide in slide rail 54, pulley 55 drives sliding net 53 to slide, the delivery port is opened, and the seedling body is dropped into net box 2 through the delivery port. After delivery, the sliding net 53 is driven to slide by pulley 55, and the delivery port is closed.

[0064] S4. The net cage 2 and the box cover 5 are driven to move downward synchronously by the lifting assembly, the net cage 2 and the box cover 5 are kept closed, and the net cage 2 is lowered to the water depth for aquaculture operation.

[0065] S5. Drive the work platform 1 to rise to a safe height through the hydraulic latch-type lifting assembly to carry out breeding operations. During the breeding process, according to the height of the bait, open the solenoid valve at the bottom of the feeding bin 37, and the bait in the feed bin 35 enters the feeding bin 37 through the feed pipe 36. Turn on the air compressor 39 corresponding to the feeding bin 37, open the solenoid valve at the bait spray port 33, and the bait in the feeding bin 37 is sprayed out from the bait spray port 33 under the action of the air compressor 39 to feed the bait.

The magnetic block 45 cuts the magnetic lines of force to generate current for power generation. The state of the breeding platform during breeding operations is as follows: Figure 2 shown.

[0066] S6. After the aquaculture is finished, the wave energy float 4 is lifted to the bottom of the working platform 1 by the lifting assembly, and the net cage 2 and the box cover 5 are simultaneously lifted to the bottom of the wave energy float 4 by the lifting assembly, and the release port is opened by the pulley 55 to catch the aquaculture products in the net cage 2.

The fishing status of the aquaculture platform is as follows: Figure 3 shown.

[0067] S7. The aquaculture products after fishing are placed in the cargo storage area 18 and transported out by transport ships.

[0068] Repeat S3-S7 to carry out the next round of cultivation.

[0069] S8. When the operation needs to be transferred, the working platform 1 is lowered onto the wave energy buoy 4 through the hydraulic latch lifting assembly, and the net cage 2 and the box cover 5 are lifted by the lifting assembly until the box cover 5 contacts the bottom of the net cage 2, and then the piles are pulled out and towed to the next aquaculture sea area by a tugboat. The transfer of the aquaculture platform can avoid the fishing moratorium and improve economic benefits.

[0070] Therefore, the use of the lifting deep-sea aquaculture platform and aquaculture method described in the present invention can solve the problem that the existing aquaculture devices have single functions and cannot meet the needs of deep-sea aquaculture; it has the advantages of high economic benefits and stable and convenient towing.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it.
