Description

Technical Field

[0001] The present invention relates to the technical field of deep sea aquaculture, and in particular to a semi-submersible fish, abalone and algae three-dimensional aquaculture platform and a method. Background Art

[0002] In the past 20 years, the offshore aquaculture industry has flourished and gradually tended to a more professional and intelligent model. Coastal countries have built offshore aquaculture platforms in the bay to promote deep-sea aquaculture. However, there have always been many problems in solving the problem of abalone farming, resulting in a low survival rate of abalone. Abalone is a traditional precious food in China, the first of the four major seafoods, and is also known as the "ear of the ocean". Its value is self-evident. Therefore, it is particularly important to solve the problem of abalone farming at sea.

[0003] In the past, people stacked abalone wooden cages in multiple layers and placed them in the sea. When feeding abalone every day, they had to lift the abalone cages from the sea water manually, which was time-consuming and laborious. To this end, people made improvements and designed the wooden cages into steel cages, which were lifted by machines instead of by hand, thus saving time and labor. However, another problem arose, that is, this design had defects. Since the steel cage had to be lifted, there must be a gap between the steel cage and the cage frame. When diving into the seabed, the steel cage and the cage frame would collide and make noise in the process of continuous impact of sea water, which greatly affected the living environment of the abalone, leading to the loss of appetite and death of the abalone.

[0044] See also Figures 1 to 6 The present invention provides a semi-submersible fish, abalone and algae three-dimensional breeding platform. Compared with the traditional abalone breeding cage lifting method or device, the abalone breeding rack layer proposed by the present invention is fixed in the breeding cage, and the abalone breeding rack layer is raised and lowered by the floating and diving of the main hull, which saves time and labor and has no noise problem. It can include: a main hull and a breeding cage, the main hull includes a plurality of ballast tanks 1, the plurality of ballast tanks 1 are used to accommodate ballast water, the main hull is floated and dived by adjusting the ballast water volume of the ballast tanks 1, the breeding cage includes a side mesh structure 2 and a bottom mesh structure 3, the side mesh structure 2 and the bottom mesh structure 3 are connected to the main hull to form a breeding cage with a bottom surface and no top surface on the side, and the inside of the breeding cage is provided with an abalone breeding rack layer 4, and the connection between the abalone breeding rack layer 4 and the side mesh structure 2 is seamlessly connected; when the main hull dives, the breeding cages all drop below the waterline so that the abalone breeding rack layer 4 is completely submerged in the seabed; when the main hull floats, the breeding cage part rises above the waterline so that the abalone breeding rack layer 4 is completely floated out of the sea. In the present embodiment, the abalone breeding rack layer 4 is seamlessly fixed in the breeding cage, so there is no gap to be hit by waves, thereby avoiding the problem of noise. In addition, when it is necessary to feed abalone, the ballast water volume of the ballast tank 1 is adjusted to make the main hull float up, so that the abalone culture rack layer 4 all floats out of the sea surface as the main hull floats up, and the staff can feed all abalones at the same time, greatly improving the efficiency of feeding and achieving the effect of saving time and labor. Therefore, this breeding platform provides a very innovative idea of ​​feeding abalone.

[0045] See again Figure 1 and Figure 4 , Figure 1The structure of the main hull is shown, which may include: a main deck 5, and a first deck 6, a second deck 7, a third deck 8, a fourth deck 9 and a fifth deck 10 arranged in sequence above the main deck 5; aquaculture cages pass through the first deck 6, the second deck 7 and the third deck 8 from bottom to top and are arranged on the main deck 5; a number of ballast tanks 1 are arranged on the main deck 5, the first deck 6 and the second deck 7; a number of cabins 11 are arranged on the third deck 8 and the fourth deck 9; and a crane 12 is arranged on the fifth deck 10. Among them, the main hull can be roughly divided into a living area and a breeding area. The living area is mainly on the third deck 8, the fourth deck 9 and the fifth deck 10. The cabins of the third deck 8 include a sewage treatment room and a feed feeding room. Since the third deck 8 is the deck closest to the waterline when the main hull dives, it is more convenient to carry out sewage treatment and feed feeding on this deck. The left and right sides of the third deck 8 are also provided with sea fishing boards 19 as entertainment facilities. The staff can go sea fishing in their spare time, which further improves the living conditions on the breeding platform. The cabins of the fourth deck 9 include restaurants, offices, laboratories, lounges, etc. The staff can carry out daily work and rest on this deck, which can meet the various needs of the staff. The fifth deck 10 is also equipped with a crane 12. When the abalone breeding rack 4 needs to be transferred, it can be completed by the crane 12; the breeding area mainly includes a breeding cage that runs through the first deck 6 and the second deck 7 and is installed on the main deck 5. This breeding platform can provide a better living and working environment for people who work at sea for a long time, integrates deep-sea breeding and life, has complete functions, and can save the cost of long-distance transportation of materials.

[0046] In the above embodiment, further, a current elimination device (not shown) is arranged on both sides of the main deck 5, and the current elimination device includes a current elimination net and a driving mechanism for retracting the current elimination net, the driving mechanism is connected to the current elimination net, the current elimination net is parallel to the two sides of the main hull, and the height of the current elimination net is at least the distance from the main deck 5 to the third deck 8. Among them, the current elimination device is installed at the edges of both sides of the main deck 5, and the current elimination net can eliminate the impact of the ocean current on the main hull, further ensuring that the various organisms on the breeding platform have a better breeding environment, and the staff can also ensure a better current elimination effect by replacing the current elimination net with different mesh sizes according to the ocean current velocity. At the same time, the current elimination net can also be retracted by the driving mechanism according to the demand, and the current elimination net can be extended from the main deck 5 to the third deck 8 at the highest. After the main hull dives, the height of the current elimination net only needs to be extended from the main deck to the waterline, and after the main hull floats, the current elimination net can be folded to avoid damage.

[0047] See again Figure 2 and Figure 5In a certain embodiment, the breeding cage is divided into an upper layer and a lower layer, the upper layer is provided with an abalone breeding rack layer 4, the lower layer is provided with an artificial fish reef 13, the left and right sides of the main deck 5 and the first deck 6 are also provided with double-layer nets 14, and the front and rear ends of the main deck 5, the first deck 6 and the second deck 7 are also provided with hanging cages 15. Among them, the breeding cage can be divided into an upper and lower two-layer structure, the upper layer is the abalone breeding rack layer 4 for breeding abalone, and the lower layer is used to breed various fish. In order to better provide a habitat for fish, different types of artificial fish reefs 13 can be set according to the fish to be cultured, and the breeding area also includes double-layer nets 14 on the left and right sides of the main deck 5 and the first deck 6, and hanging cages 13 on the front and rear ends of the main deck 5, the first deck 6 and the second deck 7. Lobsters can be cultured inside the double-layer nets 14, and lobsters can eat the attachments of marine organisms, and oysters can be cultured inside the hanging cages 13. The aquaculture platform makes full use of the three-dimensional space of the main hull, and cultivates various marine organisms while cultivating abalone, thereby increasing the diversity of aquaculture and greatly improving the practicality of the aquaculture platform.

[0048] See again Figure 1In the above embodiment, further, the abalone breeding rack layer 4 has at least one rack layer, so that the number of layers of the abalone breeding rack layer can be set according to the breeding demand or the scale of the breeding cage, each layer of the abalone breeding rack layer 4 includes a plurality of abalone cages 16 and an operating channel 17, and the plurality of abalone cages 16 are seamlessly fixed on the operating channel 17. Since the abalone cages 16 and the operating channel 17 are also seamlessly fixed, when the abalone breeding rack layer 4 dives into the seabed, the seawater impacts the abalone cages 16 without generating noise, and the plurality of abalone cages 16 are gridded, specifically, the abalone cages 16 are composed of a large box divided into a plurality of small grids, preferably, a large box can be divided into 4 rows and 2 columns of small grids, such an abalone cage 16 More abalones can be raised, and the structure of the abalone cage 16 itself can be guaranteed to have no gaps, and the generation of noise is further prevented. At the same time, the design makes full use of the longitudinal space of the abalone culture frame layer 4, so that more abalone cages 16 can be arranged in the transverse space, and the abalone culture frame layer 4 also has an operating channel 17, which is convenient for the staff to move between each abalone cage 16 and feed the abalone. The marginal space of the operating channel 17 can also be used to set an algae culture area (not shown), cultivate some algae, such as kelp, laver, wakame, agar, etc., further utilize the space of the main hull, and the cultivated kelp can be used to feed abalone at the same time, so as to realize the self-sufficient function of the cultivation platform. In addition, some abalone cages 16 are also provided with a spray system 18 for spraying abalone, a spray head can be installed around the abalone cage 16 to spray abalone, preferably, a spray head can be installed above the abalone cage 16, the effect of spraying is better, the spray system 18 is connected with the ballast system (not shown) signal of the control ballast tank 1, when the main hull floats, the ballast tank 1 releases ballast water, and the ballast system transmits the signal to the spray system 18 simultaneously, and the spray system 18 automatically controls the spray head to spray water continuously or spray water intermittently, thereby ensuring that abalone will not lack water and cause death during feeding. And the whole abalone culture frame layer 4 is a modular design, which can be quickly transferred and fixed like a container.

[0049] In one embodiment, it also includes a renewable energy power generation system, which provides electricity for the main hull. The renewable energy power generation system includes a solar power generation system and a wave power generation system. The solar power generation system is arranged on the top of the main hull, and the wave power generation system is arranged at the front and rear ends of the main hull. The renewable energy power generation system equipped with this aquaculture platform can use solar energy and wave energy for complementary power supply, which not only solves the problem of deep-sea energy supply, but also meets the requirements of clean and environmental protection, and will not pollute the marine ecology.

[0050] See again Figure 3In the above embodiment, further, the solar power generation system includes a solar photovoltaic panel 20, and the solar photovoltaic panel 20 is horizontally arranged on the fifth deck 10. Specifically, a layer of solar photovoltaic panels 20 is laid flat on the fifth deck 10 for shading and power generation. Preferably, a telescopic device for the solar photovoltaic panel 20 can also be provided, so that the solar photovoltaic panel 20 can be telescoped according to needs. For example, when the crane 12 is in operation, the solar photovoltaic panel 20 can be retracted to avoid damage to it.

[0051] See again Figure 1 and Figure 2 In the above embodiment, further, the wave energy power generation system includes a wave power generation board 21, a truss support arm 22, a hinge 23 and a hydraulic cylinder (not shown in the figure), the wave power generation board 21 is welded to the truss support arm 22 and installed on the first deck 6 through the hinge 23, the hydraulic cylinder is arranged on the first deck 6, and the output shaft of the hydraulic cylinder is connected to one end of the wave power generation board 21. Under the action of waves, the wave power generation board 21 can reciprocate around the hinge 23, thereby driving the output shaft of the hydraulic cylinder to reciprocate, and then converting the wave energy into hydraulic energy, and then converting the hydraulic energy into electrical energy through the energy conversion system to supply power, so that the impact of the waves on the main hull can be eliminated, further ensuring that the various organisms on the breeding platform have a better breeding environment, and can also be used to generate electricity. Preferably, the eagle-type wave power generation board of the prior art (patent number 2016103652769) is adopted here.

[0052] In order to better understand the present invention, the breeding platform of the embodiment of the present invention is described below according to its functions.

[0053] The first part is the main hull, which includes the main deck 5 and the first deck 6, second deck 7, third deck 8, fourth deck 9 and fifth deck 10 arranged above it in sequence. These decks together provide carriers for the ballast tank 1, various cabins 11, sea fishing boards 19, aquaculture cages and renewable energy power generation systems. When not in operation, the main hull is in a state of Figure 2 In the position shown, the staff are active in various cabins 11 on the third deck 8, the fourth deck 9 and the fifth deck 10 or are sea fishing on the sea fishing board 19. During the operation, the ballast water volume in the ballast tank 1 can be adjusted as needed to make the main hull gradually float up, and the staff go down to the second deck 7, the first deck 6 and the main deck 5 to feed the oysters in the hanging cage 15 and the lobsters in the double-layer net 14 or carry out other work.

[0054] The second part is a breeding cage, which is divided into two layers, an upper layer of the breeding cage is fixedly installed with an abalone breeding rack layer 4, the abalone breeding rack layer 4 is modularly designed, and can be conveniently transferred and fixed like a container, the abalone breeding rack layer 4 includes an abalone cage 16 and an operation channel 17, first of all, the abalone cage 16 is composed of a large box divided into small grids, and its grid arrangement can raise more abalones, and at the same time, it also ensures that the structure of the abalone cage 16 itself has no gaps and will not generate noise. The abalone cage 16 is also equipped with a spray system 18 connected to the ballast system signal of the ballast tank 1, so that after the main hull floats, the spray system 18 will automatically spray Abalone sprays water to ensure that abalone does not lack water. Secondly, operating channel 17 and each abalone cage 16 are also seamlessly fixed to avoid the generation of noise. The design of action channel 17 is convenient for staff to walk between each abalone cage 16 and feed. In addition, algae culture area can also be set at the edge of operating channel 17, and not only can self-sufficiency be achieved by cultivating some algae, but also the space of abalone culture shelf 4 is fully utilized; the lower floor of the culture cage is then placed with artificial fish reef 13, and artificial fish reef 13 can provide better habitat for fish, and the kind of artificial fish reef 13 can be changed according to the fish to be cultivated. In addition, the culture cage is composed of lateral mesh structure 2 and bottom mesh structure 3, and its advantage is that if the size of mesh structure mesh is not suitable, the cultivation user can lay the conventional net of different mesh sizes on mesh structure as required, adapt to the fish of different sizes or types of cultivation. The mesh structure can transform the aquaculture cage from a floating net to a fixed net, which will prevent the floating net from moving drastically due to big waves and causing the fish inside to be entangled and killed. At the same time, it greatly extends the service life of the net, changes the current situation of frequent net replacement in traditional cages, and reduces the cost of using nets.

[0055] The third part is a renewable energy power generation system, which includes a solar power generation system and a wave power generation system. The solar power generation system is to generate electricity by laying a layer of solar photovoltaic panels 20 above the fifth deck 10 for sunshade, and the wave power generation system is to install a hydraulic cylinder at the front and rear ends of the first deck 6 and a wave power generation panel 21 connected to the output shaft of the hydraulic cylinder for wave-breaking power generation. In the renewable energy power generation system of the present invention, a power storage device can also be designed. In addition to the normal output of the electricity provided by solar energy and wave energy, the excess electricity can be stored in the power storage device for use when the sun and waves are weak. The breeding platform of the present invention makes full use of the environmental resources in which it is located, which ensures the power supply without environmental pollution.

[0056] The present invention also provides a method for cultivating a fish, abalone and algae on a semi-submersible three-dimensional cultivation platform. The method is carried out using the above-mentioned semi-submersible three-dimensional cultivation platform for fish, abalone and algae, and the specific steps include:

[0057] S1: Move the aquaculture platform to the sea area where the aquaculture is located;

[0058] S2: Open the hatches of the ballast tanks 1 of the main deck 5, the first deck 6 and the second deck 7 in sequence and inject seawater, so that the aquaculture cages gradually sink until they are completely submerged in the seabed, then fine-tune the balance of the main hull and close the hatches of the ballast tanks 1 to enter the aquaculture state;

[0059] S3: The hatch of the ballast tank 1 of the second deck 7 is opened, and the seawater is discharged through the drainage system, so that the abalone culture rack layer 4 rises to the surface of the sea, and then the hatch of the ballast tank 1 is closed, and the staff enters the operating channel 17 to feed the abalone in the abalone cage 16;

[0060] S4: The hatch of the ballast tank 1 of the second deck 7 is opened, and seawater is injected to make the abalone culture rack layer 4 descend and dive into the seabed, and enter the culture state again.

[0061] In order to better understand the present invention, the method of the present invention is described below through specific examples.

[0062] The cultivation method of the semi-submersible fish, abalone and algae three-dimensional cultivation platform of the present invention comprises the following steps: firstly, the cultivation platform is moved to a sea area suitable for cultivation, and at the same time, a solar power generation system is already in a working state to provide power for the cultivation platform; when the platform is in the cultivation sea area, the hatches of the ballast tanks of the main deck, the first deck and the second deck are opened in sequence to inject seawater, so that the main hull dives, and then the cultivation net cages, the double-layer nets and the hanging cages are completely submerged into the seabed, and each cultivated organism enters the cultivation state, and at the same time, the wave energy power generation system also enters a working state to provide power for the cultivation platform; when abalones need to be fed, the hatch of the ballast tank of the second deck is opened, and at the same time, the seawater in the ballast tank is discharged through a pumping and drainage system, so that the main hull floats up and the abalone cultivation rack layer completely floats out of the sea surface, and at this time, the staff enters the abalone cultivation rack layer to feed the abalones; when the abalone feeding operation is completed, the hatch of the ballast tank of the second deck is opened again to inject seawater, so that the abalone cultivation rack layer descends and dives into the seabed, and the abalones re-enter the cultivation state.
