Description

Technical Field

[0001] This invention relates to the field of marine aquaculture technology, specifically to a bottom cage and method for multi-species aquaculture of marine delicacies. Background Technology

[0002] Offshore wind power is an important method for developing marine new energy sources, and the sea area where offshore wind turbine foundations are built is called an offshore wind farm. The distance between wind turbine foundations in an offshore wind farm is generally between 500-1000 meters, and the foundations are connected by submarine cables laid on the seabed. To protect the safety of the offshore wind turbine foundations and submarine cables, fishing vessels are generally prohibited from entering offshore wind farms for anchored bottom trawl fishing. To efficiently utilize the sea area of ​​offshore wind farms, domestic and international efforts are promoting the integration of offshore wind farms with marine ranching, developing wind-fishery integrated marine ranching. However, due to the strong winds and high waves at offshore wind farms, and the frequent typhoon attacks in mid- and low-latitude sea areas, the risks of traditional cage aquaculture are increased. Years of practical experience in integrating offshore wind farms with marine ranching have shown that developing traditional cage aquaculture-type marine ranching at offshore wind farms not only has high operating costs but also a high risk of typhoon damage. Cages directly exposed to typhoons are often destroyed, resulting in significant economic losses. In order to make efficient use of marine resources in offshore wind farms, it is urgent to develop marine fishery resource enhancement and aquaculture equipment and facilities placed on the seabed, reduce the risks of wind-fishery integrated marine ranching, and improve the effectiveness of marine fishery resource enhancement and aquaculture.

Detailed Implementation

[0045] To make the objectives, technical solutions, and beneficial effects of this invention clearer, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments.

[0046] like Figures 1 to 3 As shown, this invention provides a multi-species aquaculture cage for marine delicacies, characterized in that it comprises:

[0047] The bottom cage body includes a bottom cage frame 11 and at least one aquaculture mesh tray 12 disposed in the bottom cage frame 11;

[0048] The underwater video facility includes multiple underwater video camera groups 14 corresponding to each aquaculture net 12 for collecting information on the growth of marine delicacies. Each underwater video camera group includes at least one underwater video camera 14.

[0049] The floating body is connected to the bottom cage frame 11 by cable 10 assembly. The floating body includes an inflatable floating body body 5 with an internal accommodating space and an information processing system installed in the accommodating space for receiving and processing information on the growth of marine products. The information processing system is also connected to underwater video facilities via wires.

[0050] Among them, the multi-species aquaculture cages for marine delicacies are used in offshore wind farms and other sea areas.

[0051] This invention is applicable to offshore wind farms and other marine areas. The main body of the bottom cage is sunk to the seabed of the offshore wind farm by its own weight. In this invention, the bottom cage includes a bottom cage frame 11 and aquaculture net trays 12 set inside the bottom cage. Multiple aquaculture net trays 12 are used for the aquaculture of various marine species, enabling multi-species, multi-level aquaculture of marine species in idle areas of offshore wind farms. This improves the aquaculture effect of marine fishery resources and reduces the risks associated with integrated wind and fishery marine ranching.

[0052] In detail, this invention involves the aquaculture of marine delicacies within offshore wind farm areas to develop aquaculture equipment and facilities for marine fishery resources, reduce the risks associated with integrated wind-fishery marine ranching, and improve the effectiveness of aquaculture. Furthermore, in this invention, the bottom cage sinks to the seabed between the wind turbine foundation piles under its own weight, achieving a stable base, making it suitable for installation in typhoon environments within offshore wind farm areas.

[0053] Secondly, the present invention includes a bottom cage body, an underwater video facility, and a floating body on the sea surface. The bottom cage body includes a bottom cage frame 11 and at least one aquaculture net tray 12 disposed in the bottom cage frame 11. During the aquaculture process, seedlings of marine delicacies such as sea cucumbers, abalone, sea urchins, sea snails, and scallops can be placed in the aquaculture net tray 12. They rely on marine attached organisms, plankton, marine floating algae, and benthic organisms on the bottom cage mesh as natural food, without the need to feed artificial food, thus achieving the effect of aquaculture of marine delicacies.

[0054] Meanwhile, in this invention, an underwater video device is installed in the aquaculture net 12 to collect information on the growth of marine products, so as to observe the aquaculture of marine product seedlings. The information collected by the underwater video device is transmitted back to the information processing system in the floating body on the sea surface through the cable 9. If any problems are found with the marine product seedlings, it is convenient for aquaculture personnel to remedy and correct them.

[0055] Furthermore, since this invention is also used in conjunction with a floating body, connecting the main body of the bottom cage to the floating body allows for quick location of the aquaculture bottom cage placed on the seabed, reducing the workload and risks of diving operations. Moreover, by incorporating information processing equipment into the floating body, the multi-species aquaculture bottom cage of this invention can be deployed as a whole to different locations in offshore wind farm areas, enabling large-scale deployment and significantly increasing the quantity of aquacultured marine products in idle areas of offshore wind farms, thereby improving the economic benefits of aquaculture.

[0056] Most importantly, based on years of practical experience integrating offshore wind farms and marine ranches, the operating costs of developing traditional cage aquaculture-type marine ranches in offshore wind farms are high. Furthermore, offshore wind farms are frequently exposed to strong winds and rough seas, and are prone to typhoon damage, making traditional cages susceptible to destruction. In this invention, the bottom cage, underwater video equipment, and surface float are integrated as a whole. The bottom cage is stably positioned on the seabed of the offshore wind farm by its own weight, allowing for deployment at various locations within the offshore wind farm area and enabling large-scale deployment. Compared to traditional cage aquaculture-type marine ranches, this invention enables multi-species, multi-level aquaculture of marine delicacies in the offshore wind farm area, solving the problem of existing technologies where aquaculture cages in offshore wind farms are easily damaged by typhoons and waves. Moreover, relying on natural bait eliminates the need for artificial feeding, significantly reducing the cost of aquaculture in offshore wind farms.

[0057] In some embodiments of the present invention, the bottom cage frame 11 is in the shape of a cube or a cylinder;

[0058] When the bottom cage frame 11 is a cubic bottom cage frame 11, its top surface includes 4 top side frame horizontal columns, its bottom surface includes 4 bottom side frame horizontal columns, and 4 frame vertical columns are welded between the top surface and the bottom surface.

[0059] Two intersecting horizontal bars are provided on both the top and bottom surfaces, and the two horizontal bars are respectively set along the diagonal direction of the top and bottom surfaces.

[0060] A central column connecting the top and bottom surfaces is provided at the intersection of the two horizontal bars, and side columns connecting the top and bottom surfaces are provided on all four sides of the bottom cage frame 11.

[0061] When the bottom cage frame 11 is a cylindrical bottom cage frame 11, its top surface includes a circular top surface frame, its bottom surface includes a circular bottom surface frame, and four frame columns are welded between the top surface and the bottom surface.

[0062] Two intersecting horizontal bars are provided on both the top and bottom surfaces, and the two horizontal bars are perpendicular to each other; a central column connecting the top and bottom surfaces is provided at the intersection of the two horizontal bars, and side columns connecting the top and bottom surfaces are provided on all four sides of the bottom cage frame 11.

[0063] In this embodiment, the bottom cage frame 11 can also be a cylindrical bottom cage frame 11 with the same height as the cube-shaped bottom cage frame 11, and the plane diameter of the cylindrical bottom cage frame 11 is the same as the plane side length of the cube-shaped bottom cage frame 11.

[0064] In this embodiment, a cube-shaped bottom cage frame 11 is used as an example for explanation.

[0065] In detail, in this invention, the bottom cage frame 11 is cubic in shape, with two X-shaped horizontal bars on the top and bottom surfaces. A central column and side columns are provided between the top and bottom surfaces. By dividing the central column and side columns into multiple columns of equal height, and providing horizontal supports between the side columns and the central column for supporting and / or placing the aquaculture net tray 12, a layered effect is achieved in the bottom cage frame 11. The aquaculture net tray 12 is then placed on the horizontal supports, providing support for the aquaculture net tray 12.

[0066] Among them, a lifting ring 7 is set at the intersection of the two horizontal bars on the top surface. The floating body on the sea surface is connected to the main body of the bottom cage through the lifting ring 7, so as to facilitate the connection between the floating body on the sea surface and the main body of the bottom cage, and also to make it easier for aquaculture personnel to know the location of the main body of the bottom cage.

[0067] Furthermore, the main body of the bottom cage includes multiple aquaculture mesh trays 12 of equal height, arranged in layers, and each aquaculture mesh tray 12 includes a right-angled triangular mesh tray main frame, with mesh covering the bottom and sides of the mesh tray main frame. It should be noted that if the bottom cage frame 11 is cylindrical, each aquaculture mesh tray 12 is fan-shaped.

[0068] Since all the breeding net trays 12 are of equal height and the same shape, they can be produced in a modular manner to reduce production costs. In addition, the bottom and sides of the main frame of each net tray are provided with netting, which makes it easy for breeders to put the seedlings into the breeding net trays 12.

[0069] In addition, when placing the marine seedlings into the aquaculture net tray 12, the same marine seedling can be placed in the same aquaculture net tray 12, or multiple marine seedlings can be placed together in the same net tray 12, so as to release the marine seedlings according to actual needs.

[0070] Furthermore, each wire mesh drawer main frame is detachably connected to the bottom cage frame 11 via a snap fastener 13. When the wire mesh drawer main frame is detachably connected to the bottom cage frame 11, it prevents the wire mesh drawer main frame from detaching from the bottom cage frame 11.

[0071] As a specific embodiment of this invention, in some embodiments of the present invention, the bottom cage body includes multiple layers of aquaculture netting, and each layer of aquaculture netting includes eight aquaculture nettings 12 arranged axially along the central axis of the bottom cage frame 11.

[0072] Furthermore, 14 sets of underwater video cameras are positioned at the center of the top of each aquaculture net tray 12, and each set of 14 sets of underwater video cameras includes 8 underwater video cameras 14 set at 45° to collect information about the interior of each aquaculture net tray 12.

[0073] In some embodiments of the present invention, a solar panel 1 is provided on the outer surface of the floating body. The solar panel 1 is connected to an energy storage component 4 disposed in the accommodating space via wires. After receiving solar energy, the solar panel 1 converts the energy into electrical energy and stores it in the energy storage component 4 to power other components. Since the bottom cage body, underwater video facilities, and floating body in the present invention are integrated as an independent unit, it facilitates aquaculture management by aquaculture personnel in offshore wind power areas.

[0074] In some embodiments of the present invention, the information processing system includes an image storage medium 2 for receiving information on the growth of marine products collected by an underwater video device, and a satellite transceiver unit 3 for signal transmission and reception between the marine multi-species aquaculture cage and the satellite; the image storage medium 2, the satellite transceiver unit 3 and the underwater video device are all connected to the energy storage component 4 via wires.

[0075] In detail, in this invention, the underwater video facility includes multiple underwater video lenses 14 arranged in different directions, which respectively acquire information on the condition of the marine seedlings in each aquaculture net tray 12, and can also obtain environmental information of the underwater aquaculture environment. After collecting the condition information and environmental information, the underwater video facility transmits it back to the information processing system so that aquaculture personnel can understand the growth of the marine seedlings and the underwater environment.

[0076] In this invention, the floating body comprises an inflatable floating body body 5, a solar panel 1, a cable assembly 10, and an information processing system. The solar panel 1 is disposed on the outer surface of the inflatable floating body body 5 to receive solar energy, convert it into electrical energy, and store it in an energy storage component 4 to power other components. A cable interface 6 is disposed on the bottom of the floating body, through which a cable 9 passes and connects to an underwater video camera 14. The floating body is also connected to a hanging ring 7 disposed on the bottom cage body via the cable assembly 10, achieving a connection between the floating body and the bottom cage body, thus facilitating the location of the invention for aquaculture personnel. Furthermore, the image storage medium 2 in the information processing system receives information collected by the underwater video equipment, and the location of the invention is further disclosed to aquaculture personnel via a satellite transceiver unit 3.

[0077] As a specific embodiment of the present invention, the bottom cage frame 11 in the bottom cage body is a cubic stainless steel structural frame, which is welded together by four top side frame horizontal columns, four bottom side frame horizontal columns and four side frame vertical columns. The length of each top side frame horizontal column and bottom side frame horizontal column is 2.0m, and the length of each side frame vertical column is 2.0m.

[0078] Two intersecting horizontal bars are provided on the top and bottom surfaces of the bottom cage frame 11. The two horizontal bars are arranged in an X shape and are arranged along the diagonal direction of the top or bottom surface, respectively. A central column connecting the top and bottom surfaces is provided at the intersection of the two horizontal bars.

[0079] The bottom cage frame 11 includes four sides, each side having a side post connecting the top and bottom of the bottom cage body. Each side post and the central post includes multiple posts of equal height. Horizontal supports for supporting and / or placing the aquaculture net tray 12 are provided between the side posts and the central post on the same horizontal plane. The height between the upper and lower horizontal supports is 20.0 cm. Furthermore, the side posts are equipped with latches 13 that are detachably connected to the aquaculture net tray 12. When the net tray body frame is connected to the bottom cage frame 11, this prevents the net tray body frame from detaching from the bottom cage frame 11. When the latches 13 are open, the net tray body frame and the bottom cage frame 11 can be separated, allowing aquaculture personnel to remove the aquaculture net tray 12 to place marine seedlings or remove marine products.

[0080] In this embodiment, each aquaculture net tray 12 has a right-angled triangle bottom surface with a right-angled side length of 100.0cm, and each aquaculture net tray 12 has a height of 20.0cm. The bottom surface and three sides are provided with a net with a mesh size of 1.0cm. That is, in this embodiment, there are 8 aquaculture net trays 12 per layer, and a total of 80 trays for 10 layers.

[0081] The underwater video facility includes multiple underwater video lenses 14 and cables 9. The underwater video lenses 14 are located at each level of the central pillar, with eight lenses 14 per level, arranged at equal angles of 45°. Each underwater video lens 14 faces each aquaculture net tray 12. Cables 9 connect to each underwater video lens 14, and the connecting cables converge at the central pillar and are tied together with ropes 10 to connect to the solar panels of the floating body on the sea surface.

[0082] The floating body comprises an inflatable float body 5, solar panels, a cable assembly 10, and an information processing system. The inflatable float body is connected to a lifting ring 7 on the top surface of a cubic stainless steel structural frame via cables 10 from the cable assembly 10. The electrical energy generated by the solar panels is stored in an energy storage component 4 within the inflatable float body. The energy storage component 4 is preferably a battery.

[0083] The cable assembly 10 includes a cable 10 and a cable, which can be bundled together by cable ties 8. One end of the cable 10 is connected to the bottom of the surface float, and the other end is connected to a lifting ring 7 on the top surface of the cubic stainless steel structural frame. The cable connects the battery in the inflatable float to the underwater video camera 14 mounted on the central column.

[0084] Preferably, the inflatable float is red or orange, based on the vibrancy of the color, so that aquaculture personnel can easily see the position of the float on the sea surface. A stainless steel lifting ring 7 is provided at the intersection of the two horizontal bars on the top surface for connecting the cable 10 assembly, which facilitates the attachment of the cable 10 to lift and lower the bottom cage body.

[0085] Another aspect of the present invention provides a method for cultivating multiple species of seafood using a bottom cage, comprising the following steps:

[0086] S1. Transport the multi-species aquaculture cages of marine delicacies to the offshore wind farm area, and select a flat seabed as the bottom area for the multi-species aquaculture cages of marine delicacies.

[0087] S2. Place multiple species of marine delicacies into at least one aquaculture net tray 12.

[0088] S3. Secure the aquaculture mesh tray 12 to the bottom cage frame 11 using the buckle 13;

[0089] S4. Using hoisting equipment, place the multi-species aquaculture cages for marine delicacies into the seawater. Under the action of gravity, the multi-species aquaculture cages for marine delicacies slowly sink until they sit stably on the seabed.

[0090] S5. Connect the floating body on the sea surface and the multi-species aquaculture bottom cage of marine delicacies through the cable 10 assembly, and connect the solar panel 1 and the energy storage component 4 through the wire to place the floating body on the sea surface and complete the deployment of the multi-species aquaculture bottom cage of marine delicacies.

[0091] S6. Regularly monitor the growth and development of different marine seedlings in the multi-species aquaculture cages using underwater video equipment;

[0092] S7. When the marine delicacies seedlings grow to the size that can be harvested, the harvesting vessel sails to the floating area on the sea surface, lifts the multi-species aquaculture bottom cages of marine delicacies using hoisting equipment, places them on the deck of the ship, and opens the aquaculture net trays 12 one by one to harvest the marine delicacies products.

[0093] S8. Repeat steps S1-S7 above, and adjust the stocking density of the marine delicacies seedlings based on the effect of the previous aquaculture, and carry out the second aquaculture.

[0094] The aforementioned hoisting equipment can be a ship-mounted winch.

[0095] In detail, a specific embodiment of the multi-species aquaculture cage method for marine delicacies of the present invention includes the following steps:

[0096] The multi-species aquaculture cages for marine delicacies are transported to the offshore wind farm area, and a flat seabed is selected as the seabed substrate area for the multi-species aquaculture cages.

[0097] Seedlings of various seafood species, including sea cucumber, abalone, sea urchin, conch, and scallop, were stocked in 80 aquaculture net trays (12 in total). Seedlings with a shell length or body length greater than 1.50 cm were selected to maintain a density of 50-80 seedlings per m². 2 Based on the biological life and feeding habits of sea cucumbers, abalone, sea urchins, conches, scallops, and other marine delicacies, one type of marine delicacy seedling can be placed in each layer, or two or three types of seedlings can be mixed. At the top layer, large seaweeds such as Sargassum fusiforme and Sargassum fusiforme can be cultivated to meet the feeding needs of the marine delicacy seedlings, serving as food for the sea cucumbers, abalone, and sea urchins below. Abalone, sea urchins, conches, scallops, and sea cucumbers are then placed in each layer from top to bottom, respectively.

[0098] After the marine seedlings have been released, each aquaculture basket 12 is pushed into the cubic stainless steel structural frame, and each aquaculture buckle 13 is closed.

[0099] Connect cable assembly 10 to ship-mounted winch cable 10, place the multi-species aquaculture cage in seawater, and start the ship-mounted winch. Under the action of gravity, the multi-species aquaculture cage slowly sinks with the rotation of the winch until it sits stably on the seabed. Divers descend to the seabed to check whether the multi-species aquaculture cage is sitting stably on the bottom.

[0100] Connect the cable 10 at the sea surface end of the cable 10 assembly to the bottom end of the sea surface float, connect the cable to the battery in the inflatable sea surface float, place the sea surface float on the sea surface to complete the bottom cage deployment for multi-species aquaculture of marine delicacies.

[0101] Regularly monitor the growth and development of different marine species seedlings in the multi-species aquaculture cages using remote video terminal equipment. If any major problems are found, take timely remedial and corrective measures.

[0102] When the marine delicacies seedlings grow to harvestable size, the harvesting vessel sails to the floating area on the sea surface, connects the bottom cable 10 of the floating body to the ship's winch, starts the ship's winch, lifts the multi-species aquaculture cages of marine delicacies and places them on the ship's deck, and opens the aquaculture net trays 12 one by one to harvest the marine delicacies products.

[0103] The aquaculture seedlings were then placed back into each aquaculture cage 12. Based on the results of the previous aquaculture, the stocking density of the seedlings was adjusted appropriately. The latches 13 of each aquaculture cage 12 were then closed. The multi-species aquaculture cage was then lowered back into the seawater and allowed to slowly sink to the seabed for a second aquaculture operation.
