[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention are within the scope of protection of the present invention.

[0031] like Figures 1 to 4As shown, an embodiment of the present invention provides a marine aquaculture cage capable of drying nets, the marine aquaculture cage capable of drying nets comprises a net 10, a support member 20 and a dynamic ballast 30. The net 10 is a cylindrical structure, the support member 20 is arranged in the net 10 to support the net 10, the dynamic ballast 30 is arranged on the support member 20, the dynamic ballast 30 comprises an active module 31, a passive module 32 and a guide tube 33, the active module 31 comprises a first cylinder 311, an active piston member 312 and a driving member 313, the active piston member 312 is movably arranged in the first cylinder 311, the active piston member 312 divides the inner cavity of the first cylinder 311 into an active air chamber 3111 and an active water chamber 313. 12, the driving member 313 can drive the active piston member 312 to move, the passive module 32 includes a second cylinder body 321 and a passive piston member 322, the passive piston member 322 is movably arranged in the second cylinder body 321, the passive piston member 322 divides the inner cavity of the second cylinder body 321 into a passive air chamber 3221 and a passive water chamber 3222, the two ends of the conduit 33 are respectively connected to the active water chamber 3112 and the passive water chamber 3222, and the first cylinder body 311 and the second cylinder body 321 are arranged at intervals along the circumference of the net clothing 10.

[0032] The marine aquaculture cage using the net drying device can support the net 10 by using the support member 20, so that the net 10 maintains a cylindrical structure. The driving member 313 of the active module 31 of the dynamic ballast 30 drives the active piston member 312 to move in the first cylinder 311, and the active piston member 312 is used to adjust the volume ratio of the active air chamber 3111 and the active water chamber 3112. Since the two ends of the conduit 33 are respectively connected to the active water chamber 3112 and the passive water chamber 3222, the volume ratio of the passive air chamber 3221 and the passive water chamber 3222 of the passive module 32 can also be adjusted accordingly, so that the weight of the active water chamber 3112 and the passive water chamber 3222 changes, and the center of gravity of the support member 20 is adjusted, so that the support member 20 drives the net 10 to rotate, so that the net 10 near the position originally submerged in the water rises out of the water surface and is exposed to sunlight, thereby removing biological attachment.

[0033] In addition, a dynamic ballast is used for balance adjustment. The dynamic ballast adopts a main and passive module design. The ballast water is balanced and adjusted in the main and passive modules. It is a completely closed system and does not exchange media with the outside world. Therefore, it can avoid external contamination and the reliability of the equipment is higher.

[0034] It should be noted that the part of the net 10 exposed to the sea surface 70 is exposed to the sun, and the tiny marine organisms attached to the net 10 will be killed or fall off, thereby preventing the growth and expansion of the attached marine organisms. The rotation of the support 20 can drive the net 10 to rotate, so that different parts of the net 10 can be alternately raised above the sea surface 70 to be exposed to the sun according to a certain period, thereby preventing the formation of larger marine organisms attached to the net 10.

[0035] Specifically, the active air chamber 3111 and the passive air chamber 3221 of the dynamic ballast are filled with air, nitrogen or other inert gases, and the active water chamber 3112 and the passive water chamber 3222 of the dynamic ballast are filled with pure water.

[0036] like Figure 1 As shown, the support member 20 includes a plurality of support rings 21, which are arranged at intervals along the axial direction of the net 10, and the support rings 21 are coaxially arranged with the net 10. By providing a plurality of support rings 21, the net 10 can improve its adaptability to complex marine environments while maintaining its shape.

[0037] In this embodiment, a dynamic ballast 30 is provided on each support ring 21 , which can improve the adjustment accuracy and adjustment flexibility.

[0038] Specifically, the plurality of support rings 21 are arranged at equal intervals along the axial direction of the net 10 .

[0039] In this embodiment, the first cylinder 311 and the second cylinder 321 are centrally symmetrically arranged in the circumferential direction of the support ring 21. The centrally symmetrical layout ensures the balance of the offshore aquaculture cage during adjustment, and improves the safety and reliability of the aquaculture cage.

[0040] like Figure 3 As shown, a plurality of dynamic ballasts 30 are provided on the support ring 21, and the plurality of dynamic ballasts 30 are arranged at equal intervals in the circumferential direction of the support ring 21. The layout of the dynamic ballasts 30 at equal intervals can more evenly adjust the buoyancy of the cage, making the cage more stable in the water.

[0041] Specifically, the equidistant arrangement of the dynamic ballasts 30 can distribute the buoyancy and pressure more evenly, making the cages more stable when adjusting the depth, which helps to improve the success rate and economic benefits of aquaculture.

[0042] In this embodiment, no less than three sets of dynamic ballasts are installed on each support ring 21 .

[0043] In this embodiment, the support ring 21 is a circular ring structure. The support ring 21 with a circular ring structure can provide uniform support force, so that the net keeps a good shape, is conducive to the growth and activity of fish, and is suitable for the cultivation of various marine organisms.

[0044] Specifically, the design of the annular support ring 21 not only provides uniform support force, but also optimizes the internal space of the cage, which is conducive to the free swimming and foraging of fish. It is suitable for the breeding of various marine organisms, especially fish species that have high requirements for growth space.

[0045] In this embodiment, the marine aquaculture cage capable of drying nets further comprises a cable, one end of which is electrically connected to the driving member 313, and the other end of which is electrically connected to the marine power generation device 40. Through the connection between the cable and the marine power generation device 40, the dynamic ballast 30 can obtain a stable power supply, which is suitable for aquaculture scenarios combined with new energy facilities such as offshore wind power and offshore photovoltaic power generation, and realizes the dual benefits of energy and aquaculture.

[0046] Moreover, the installation of the cable not only provides stable power for the dynamic ballast 30, but also realizes seamless connection with marine new energy facilities, such as offshore wind power, offshore photovoltaic, etc., which not only ensures the automatic operation of the cage, but also makes full use of offshore space resources, realizes the dual benefits of energy and aquaculture, and provides new ideas for the green development of the marine economy.

[0047] In this embodiment, the cable is connected to each support ring in sequence to provide power to each support ring.

[0048] Specifically, the driving member 313 includes an electric push rod, which is disposed in the active air chamber 3111, one end of which is connected to the inner wall of the active air chamber 3111, and the other end of which is connected to the active piston member 312. The use of the electric push rod makes the adjustment of the dynamic ballast 30 more accurate and faster, and is suitable for aquaculture environments where the angle of the cage needs to be adjusted frequently.

[0049] like Figure 1 As shown, the marine aquaculture cage capable of drying nets further comprises a mooring cable 50, a first end of which is connected to a first end of the net 10, and a second end of which can be connected to an offshore power generation device 40. The provision of the mooring cable 50 ensures a stable connection between the aquaculture cage and the power generation device, is suitable for sea areas with strong winds and waves, and ensures the safety of the aquaculture cage.

[0050] Specifically, the use of mooring cable 50 provides a secure connection between the cage and the power generation device, and can maintain stability even in sea areas with strong winds and waves. It is suitable for breeding fish species with high environmental requirements, ensuring that they grow in a safe environment and reducing losses caused by bad weather.

[0051] like Figure 1As shown, in this embodiment, the marine aquaculture cage capable of drying nets further comprises a fixed anchor 60, which is connected to the second end of the net 10 and can be connected to the seabed 80. The use of the fixed anchor 60 increases the stability of the aquaculture cage and prevents the cage from drifting due to water flow or wind.

[0052] Specifically, the provision of the fixed anchor 60 not only increases the stability of the cage, but also prevents drifting due to deep-sea currents and wind, and is suitable for deep-sea aquaculture environments, such as aquaculture of deep-sea fish, thereby improving the safety and efficiency of aquaculture and reducing losses caused by position changes.

[0053] In this embodiment, both ends of the net are gradually closed in a trumpet shape, one end of which is connected and fixed to the offshore new energy infrastructure through a mooring cable 50 , and the other end is connected to a fixed anchor 60 .

[0054] In this embodiment, the offshore aquaculture cage that can dry the net is used at the same site as the offshore new energy and can realize the offshore aquaculture cage structure of periodic automatic drying of the net through the buoyancy adjustment of the floating structure (dynamic ballast 30), thereby avoiding the large-scale attachment of marine organisms, thereby ensuring the safety of the offshore aquaculture cage and the integrated offshore new energy facilities.

[0055] In this embodiment, the marine aquaculture cages capable of drying nets are generally arranged in a horizontal cylindrical cage shape, suspended in the seawater, the diameter of the support ring 21 is D, 10% to 30% of the marine aquaculture cages have a height range of D above the sea surface 70°, and the remaining 70% to 90% of the marine aquaculture cages have a height range of D below the sea surface 70°. This design ensures that the nets can be fully exposed to sunlight for natural disinfection, while maintaining sufficient underwater space for fish activities.

[0056] The support ring 21 may be made of a metal and chemical polymer composite material and has a certain rigidity.

[0057] It should be noted that the net 10 is exposed to the sun periodically, and its period and time are automatically adjusted by the control module of the active module of the dynamic ballast. This automatic adjustment mechanism can optimize the net drying time according to environmental factors such as seawater temperature and light intensity.

[0058] In this embodiment, the cable has waterproof and corrosion-resistant properties. The waterproof and corrosion-resistant cable can ensure the stability and safety of power transmission and is suitable for long-term use in a marine environment.

[0059] In order to facilitate understanding of the marine aquaculture cage with drying nets provided in this embodiment, a specific embodiment is described below:

[0060] Each support ring 21 is equipped with four pairs of dynamic ballasts, A, B, C, and D, of which A1, B1, C1, and D1 are active modules of the dynamic ballasts, and A2, B2, C2, and D2 are passive modules of the dynamic ballasts. Figure 3 Starting from the position, to realize the counterclockwise rotation of the support ring 21, the electric push rod in the active module at the dynamic ballast position A1 is retracted, and the active piston is pulled to make the water in the passive water chamber of the dynamic ballast passive module at the dynamic ballast position A2 flow back to the active water chamber of the dynamic ballast active module at the dynamic ballast position A1; at the same time, the electric push rod in the active module at the dynamic ballast position B1 is retracted, and the active piston is pulled to make the water in the passive water chamber of the passive module at the dynamic ballast position B2 flow back to the active water chamber of the dynamic ballast active module B1; at the same time, the electric push rod in the active module at the dynamic ballast position C1 is extended, and the active piston is pushed to make the water in the active water chamber of the dynamic ballast active module at the dynamic ballast position C1 flow back to the active water chamber of the dynamic ballast active module at the dynamic ballast position C1. The water in the active water chamber of the dynamic ballast passive module at position C2 is squeezed into the passive water chamber of the dynamic ballast passive module at position C2; at the same time, the electric push rod in the active module at position D1 of the dynamic ballast is extended, pushing the active piston to squeeze the water in the active water chamber of the active module of the dynamic ballast at position D1 into the passive water chamber of the dynamic ballast passive module at position D2. Due to the redistribution of the water volume in the water chambers of the main and passive modules of each ballast, the center of gravity of the support ring 21 is changed, so that the support ring 21 is rotated 45° counterclockwise and balance is achieved again. The rotation of the support ring 21 drives the net 10 installed thereon to rotate, so that the net 10 near position C1 that was originally submerged in the water rises out of the water surface to be exposed to sunlight, thereby removing biological attachment.

[0061] It should be noted that the support ring 21 can rotate clockwise or counterclockwise. When the net 10 rotates more than 360° in one direction, a 360° exposure cycle of the net 10 is achieved. In order to prevent excessive twisting of the mooring line 50 and the cable, in the next exposure cycle, the support ring 21 drives the net 10 to rotate in the opposite direction.

[0062] Specifically, the total horizontal length of the aquaculture cage is 210m, the length of the mooring cable is 30m, the diameter of the support ring is 30m, the number of support rings is 6, the spacing between support rings is 30m, and 4 groups of dynamic ballasts are installed on each support ring.

[0063] like Figure 1 As shown, an embodiment of the present invention provides an offshore new energy device, which includes an offshore power generation device 40 and an offshore aquaculture cage with a drying net, and the offshore aquaculture cage with a drying net is the offshore aquaculture cage with a drying net provided above.

[0064] In this embodiment, the offshore power generation device 40 is an offshore wind power foundation. The offshore wind power foundation provides a stable support and power supply for the aquaculture cages, is suitable for sea areas with rich wind resources, and provides a comprehensive solution for marine aquaculture and new energy development. Specifically, the use of the offshore wind power foundation not only provides a stable support for the aquaculture cages, but also solves the problem of power required for aquaculture. It is particularly suitable for sea areas with rich wind resources, provides a comprehensive solution for marine aquaculture and new energy development, and realizes efficient utilization of resources and harmonious coexistence of ecology.

[0065] In this embodiment, the offshore power generation device 40 is an offshore photovoltaic foundation. The offshore photovoltaic foundation not only provides electricity for the aquaculture cages, but also can block part of the sunlight, which is suitable for sea areas with strong sunlight and high temperature, and provides a more suitable growth environment for fish. Specifically, the setting of the offshore photovoltaic foundation not only meets the power demand of the aquaculture cages, but also can adjust the temperature of the aquaculture environment by blocking the sunlight. It is particularly suitable for sea areas with strong sunlight and high temperature, such as the Mediterranean and the Red Sea, providing more suitable growth conditions for fish, which is conducive to improving the quality and yield of aquaculture.

[0066] In addition, the arrangement of the offshore aquaculture cages that can be used for drying nets provided in this embodiment is that they are arranged along the main tidal direction in the site, that is, the connection line between the fixed anchor and the offshore new energy foundation is parallel to the main tidal direction of the local sea area, in order to reduce the scouring load of seawater on the cages due to tidal movement.

[0067] Through the device provided in the embodiment, the exposed part of the net can be automatically adjusted, the sunlight can be effectively used for natural disinfection of the net, biological attachment can be reduced, the service life of the net can be extended, and the cost of manual maintenance can be reduced. By combining with offshore new energy devices, not only the automated management of aquaculture cages is realized, but also the offshore space resources are fully utilized, the dual benefits of energy and aquaculture are achieved, and new ideas and solutions are provided for the sustainable development of marine resources. In addition, the structure can also be customized according to different sea conditions and aquaculture needs, such as combining offshore wind power foundations in sea areas with abundant wind resources, and combining offshore photovoltaic foundations in sea areas with abundant sunshine, which further optimizes the aquaculture environment, improves aquaculture efficiency and benefits, and opens up a new path for the green development of the marine economy. The flexibility and adaptability of this structure enable the aquaculture cages to be customized according to the characteristics and aquaculture needs of different sea areas, such as combining offshore wind power foundations in sea areas with abundant wind resources, which is suitable for aquaculture of fish species with strong adaptability to wind and waves, such as aquaculture of sea bass; combining offshore photovoltaic foundations in sea areas with abundant sunshine, which is suitable for aquaculture of fish species with specific requirements for lighting conditions, such as aquaculture of red sea fish. This customized design not only optimizes the aquaculture environment and improves aquaculture efficiency, but also achieves dual benefits of energy and aquaculture, contributes innovative power to the green development of the marine economy, and has broad market prospects and application value.
