Description

Technical Field

[0001] The utility model belongs to the technical field of deep-sea aquaculture vessels and relates to a combined aquaculture system of a gravity-type net cage and aquaculture cabin. Background Art

[0002] Deep sea waters have significant advantages such as rich fishery resources, high-quality water sources, suitable water temperature and being away from land-based pollution and diseases. They have excellent conditions for carrying out large-scale marine aquaculture and logistics processing and supply, and are new space for the development of modern aquaculture and marine economy.

[0003] Aquaculture vessels are one of the core equipment for developing deep-sea aquaculture projects. They can reach deep sea areas that ordinary aquaculture cages cannot reach, and have high economic and social value. Aquaculture vessels are equipped with several large aquaculture cabins in the shape of a "wide-mouth bottle". They are exchanged with external seawater through a circulating water pump. The aquaculture water depth of each aquaculture cabin can reach 15m, and the number of fish grown can reach more than 100 tons. Using aquaculture vessels for fish farming can greatly increase fish production.

[0004] At present, during the process of fish farming in the cabin of aquaculture workers, after the fry enter the cabin, some smaller fry are easily threatened by foreign species such as trash fish and crabs brought in by circulating water, which seriously affects the survival and feeding of the young fish. At the same time, due to the large cabin, that is, the large aquaculture water body, on the one hand, it is difficult to control the management and growth of the young fish, and on the other hand, the feed for the young fish is mainly slow-sinking feed, which will make it difficult to calculate the feed coefficient when the fry are small, and the sinking of the slow-sinking feed will also lead to a large amount of feed waste and damage to the aquaculture water quality, which is not conducive to refined production.

[0005] Therefore, by further optimizing the onboard aquaculture system, the juveniles can be placed in the cabin after being cultivated to a certain size under relatively easy management, ensuring the feeding and survival rate of the juveniles, and providing favorable conditions for the full-cycle aquaculture of cabin fish. Continuously improving the research and development and testing technology system of deep-sea aquaculture vessels can provide strong support for the steady development of subsequent large-scale aquaculture vessels for smart fisheries and the mechanization, intelligence and informatization of modern aquaculture. Utility Model Content

[0006] In view of the shortcomings of the above-mentioned prior art, the utility model provides a combined farming system of a gravity cage and a farming cabin, which realizes the complementary advantages of the cage and the farming cabin, can effectively resist the invasion of alien species for smaller fry, improve feeding efficiency, and further realize the development of three-dimensional farming or multi-species mixed farming models.

[0007] The utility model discloses a combined aquaculture system of a gravity cage and aquaculture cabin, comprising a aquaculture cabin, characterized in that it also comprises a gravity cage and a traction device for fixing the gravity cage in the aquaculture cabin, wherein a distance is provided between the periphery of the gravity cage and the inner wall of the aquaculture cabin;

[0008] The traction device includes a lateral force traction component and a longitudinal force traction component, wherein the lateral force traction component is arranged between the walkway on both sides of the breeding cabin ship's side and the gravity-type cage, and the longitudinal force traction component is arranged between the walkway on both sides of the breeding cabin's bow and stern and the gravity-type cage.

[0009] The utility model effectively combines the gravity cage with the breeding cabin. The gravity cage occupies a part of the space in the breeding cabin, and the two share the circulating breeding seawater in the breeding cabin. In this mode, the gravity cage and the breeding cabin form relatively independent breeding spaces, and can be selectively distributed between the two according to the specifications of the fry or the breeding varieties. For example, the young fish in the cage can be protected from the threat of alien species, and can be accurately fed to achieve refined production management; for example, multi-variety co-breeding and effective distribution of different varieties can improve the stability and diversity of the ecosystem in the cabin, enhance the resistance of fish, and reduce feed waste and breeding costs. The utility model fixes the gravity cage in the breeding cabin by designing a traction device, and can effectively avoid the problem of the gravity cage colliding with the inner wall of the breeding cabin due to the swaying of the water body.

[0010] As a preferred solution, the gravity cage includes a frame structure, a buoy and a net; wherein, a plurality of buoys are arranged at the bottom of the frame structure, and a net is hung at each opening of the frame structure. Compared with the traditional gravity cage with a single opening and a large cage structure, the utility model adopts a design scheme of mounting multiple nets on a frame structure, realizes the layout and reasonable use of the space inside the cage, and can further realize the hierarchical distribution of fish or the mixed breeding of multiple species.

[0011] As a preferred solution, the frame structure is composed of pedals. With the pedals, the farmers can walk on the pedals under the premise of certain safety measures, so as to facilitate the management of the breeding production.

[0012] As a preferred solution, a sinker is tied to the mesh bar at the bottom of the net, or a net bottom sinker is placed in the bottom of the net, and the gravity and tension of the sinker or net bottom sinker are used to tighten the net and maintain the shape of the net box.

[0013] As a preferred solution, the longitudinal force traction assembly includes a bow side anchor rope group and a stern side anchor rope group, wherein the bow side anchor rope group includes a plurality of anchor ropes arranged between a walkway on the bow side of the aquaculture cabin and a gravity-type cage, and the stern side anchor rope group includes a plurality of anchor ropes arranged between a walkway on the stern side of the aquaculture cabin and a gravity-type cage. Since the swaying of the hull is mainly concentrated between the port side and the starboard side of the hull, the swaying in the bow and stern directions is relatively light, therefore, as a preferred solution, the anchor ropes in the bow side anchor rope group and the anchor ropes in the stern side anchor rope group are in a straightened state.

[0014] As a preferred solution, the lateral force traction assembly includes a port side anchor rope group and a starboard side anchor rope group, wherein the port side anchor rope group includes a plurality of anchor ropes arranged between the walkway on the port side of the breeding cabin and the gravity cage, and the starboard side anchor rope group includes a plurality of anchor ropes arranged between the walkway on the starboard side of the breeding cabin and the gravity cage. Since the swaying of the hull is mainly concentrated between the port side and the starboard side of the hull, as a preferred solution, the anchor ropes in the port side anchor rope group and the anchor ropes in the starboard side anchor rope group are in a relaxed state, and the relaxation amount is less than the distance from the side wall on the port side or the side wall on the starboard side of the breeding cabin to the adjacent gravity cage, so as to prevent the gravity cage from colliding with the breeding cabin wall during the accompanying water swaying.

[0015] The beneficial effects of the utility model are:

[0016] (1) The gravity cage and the breeding cabin are effectively combined to form a relatively independent breeding space. Smaller fry can be temporarily raised in the gravity cage to avoid the threat of foreign species, and can be accurately fed. After growing to a larger size, they can be put into the breeding cabin for breeding;

[0017] (2) Gravity cages and aquaculture chambers can form multiple relatively independent aquaculture areas, facilitating the development of a multi-species mixed-breeding model. Effective distribution of different species can improve the stability and diversity of the ecosystem in the chamber, enhance fish resistance, and reduce feed waste and aquaculture costs.

[0018] (3) By designing a traction device to fix the gravity cage in the aquaculture cabin, the structure of the original aquaculture cabin of the aquaculture vessel will not be damaged, the development cost and the use cost will be greatly reduced, and the problem of the gravity cage colliding with the inner wall of the aquaculture cabin due to the swaying of the water body can be effectively avoided.

[0029] Embodiment 1:

[0030] like Figure 1-Figure 2 As shown, a combined aquaculture system of a gravity cage and aquaculture cabin is located inside a aquaculture vessel, and includes a aquaculture cabin 1, a gravity cage, and a traction device for fixing the gravity cage in the aquaculture cabin 1, wherein a distance is provided between the periphery of the gravity cage and the inner wall of the aquaculture cabin 1;

[0031] As an embodiment, the aquaculture cabin 1 is a wide-mouth bottle structure, and a platform 10 for aquaculture personnel or crew members to walk and work is arranged around the aquaculture water body. The aquaculture water body is circulated with external seawater through a pump. The aquaculture area of ​​the aquaculture cabin 1 is usually designed to be about 21m long×20m wide×14m high (water depth).

[0032] As an embodiment, the gravity cage includes a frame structure 2, a buoy 3 and a net 4; Figure 2 As shown, the frame structure 2 is divided into 3 rows along the left and right sides of the ship, and into 5 columns along the bow and stern, forming 15 openings, each of which is about 10 square meters. A number of buoys 3 are arranged at the bottom of the frame structure 2, and a net 4 is hung at each opening of the frame structure 2. The height of the net 4 is about 5 meters, so that each opening has about 50 cubic meters of aquaculture water. This structural design can effectively realize the hierarchical distribution of fry of multiple specifications, and can also realize comparative verification experiments of different distributions of the same specification, which is convenient for production and scientific research. Compared with the traditional gravity-type cage with a single opening and large cage structure, this embodiment adopts the design scheme of mounting multiple nets 4 on the frame structure 2, which realizes the layout and rational use of the space inside the cage, and can further realize the hierarchical distribution of fish or the mixed breeding of multiple varieties.

[0033] As an implementation mode, the frame structure 2 is composed of pedals, and the width of the pedals is usually designed to be about 40 cm, so that under the premise of certain safety measures, the breeding staff can walk on the pedals to facilitate the management of breeding production.

[0034] As an implementation mode, a sinker 5 is attached to the mesh bar at the bottom of the net 4. The gravity of the sinker 5 is used to tighten the net 4 and maintain the shape of the net box.

[0035] As an embodiment, the traction device includes a lateral force traction component and a longitudinal force traction component.

[0036] As an embodiment, the lateral force traction assembly is arranged between the walkway 10 on both sides of the ship's side of the aquaculture cabin 1 and the gravity cage. Specifically, Figure 2 As shown, the lateral force traction assembly includes a port side anchor rope group 8 and a starboard side anchor rope group 9; the port side anchor rope group 8 includes two anchor ropes arranged between a walkway 10 on the port side of the culture cabin 1 and the gravity cage, wherein one end of an anchor rope (referred to as rope A) is tied to the walkway 10 on the port side of the culture cabin 1, and the other end is tied to the opening of the walkway 10 on the bow side of the gravity cage and away from the port side of the culture cabin 1; one end of the other anchor rope (referred to as rope B) is tied to the walkway 10 on the port side of the culture cabin 1, and the other end is tied to the stern side of the gravity cage and away from the culture cabin 1. The starboard side anchor rope group 9 includes two anchor ropes arranged between the starboard side of the breeding cabin 1 and the gravity cage, wherein one end of one anchor rope (referred to as C rope) is tied to the starboard side of the breeding cabin 1, and the other end is tied to the bow side of the gravity cage and away from the opening 10 of the walkway on the starboard side of the breeding cabin 1; the other anchor rope (referred to as D rope) has one end tied to the starboard side of the breeding cabin 1, and the other end is tied to the stern side of the gravity cage and away from the opening 10 of the walkway on the starboard side of the breeding cabin 1. Since the sloshing of the hull is mainly concentrated between the port side and the starboard side of the hull, specifically, the anchor ropes in the port side anchor rope group 8 and the anchor ropes in the starboard side anchor rope group 9 are in a slack state, and the slack amount is smaller than the distance from the port side wall or the starboard side wall of the aquaculture cabin 1 to the adjacent gravity cage, so as to prevent the gravity cage from colliding with the inner wall of the aquaculture cabin 1 during the sloshing of the water body. In order to ensure the force balance of the gravity cage under the action of the traction device when the water body is sloshing, the A rope and the C rope are tied together at the intersection of the two ropes with a tying rope 11, and the B rope and the D rope are tied together at the intersection of the two ropes with a tying rope 11.

[0037] The above-mentioned setting method of the lateral force traction component is only one of many methods, and the applicant does not impose any restrictions on this. It only needs to ensure that the gravity cage will not collide with the inner wall of the breeding cabin 1 during the sloshing of the water body, such as directly tying the gravity cage at the adjacent position with an anchor rope on the walkway 10 on the left and right sides of the ship's side of the breeding cabin 1.

[0038] As an embodiment, the longitudinal force traction assembly is arranged between the walkway 10 on both sides of the bow and stern of the breeding cabin 1 and the gravity cage. Specifically, the longitudinal force traction assembly includes a bow side anchor rope group 6 and a stern side anchor rope group 7; the bow side anchor rope group 6 is an anchor rope arranged between the walkway 10 on the bow side of the breeding cabin 1 and the gravity cage at an adjacent position, and the stern side anchor rope group 7 is an anchor rope arranged between the walkway 10 on the stern side of the breeding cabin 1 and the gravity cage at an adjacent position, and the two anchor ropes are distributed on both sides of the axis of the gravity cage in the bow and stern direction. Since the swaying of the hull is mainly concentrated between the port and starboard sides of the hull, and the swaying in the bow and stern directions is relatively light, the anchor ropes in the bow side anchor rope group 6 and the anchor ropes in the stern side anchor rope group 7 are in a straightened state.

[0039] The above-mentioned setting method of the longitudinal force traction component is only one of many methods, and the applicant does not impose any restrictions on this. It only needs to ensure that the gravity cage will not collide with the inner wall of the breeding cabin 1 during the sloshing of the water body. For example, the number of anchor ropes can be increased based on the current design.

[0040] This embodiment effectively combines the gravity cage with the breeding cabin 1. The gravity cage occupies a part of the space of the breeding cabin 1, and the two share the circulating breeding seawater in the breeding cabin 1. In this mode, the gravity cage and the breeding cabin 1 form a relatively independent breeding space, and can be selectively distributed between the two according to the specifications of the fry or the breeding species. For example, the young fish in the cage can be protected from the threat of foreign species, and can be accurately fed to achieve refined production management; for another example, multi-species co-breeding and effective distribution of different varieties can improve the stability and diversity of the ecosystem in the cabin, enhance the resistance of fish, and reduce feed waste and breeding costs.

[0041] Embodiment 2:

[0042] like Figure 3 As shown, in this embodiment, the layout of the frame structure 2 of the gravity cage is adjusted, and the rest is the same as in embodiment 1. Some small openings are merged two by two to form 6 medium-sized openings of about 20 square meters, and the height of the net 4 is still maintained at about 5 meters.

[0043] Embodiment 3:

[0044] like Figure 4 As shown, this embodiment adjusts the layout of the frame structure 2 of the gravity cage, and the rest is the same as in Embodiment 2. Some of the medium-sized openings are merged two by two to form two medium-large openings of about 40 square meters, and the height of the net 4 is still maintained at about 5 meters.

[0045] Embodiment 4:

[0046] like Figure 4As shown, this embodiment adjusts the layout of the frame structure 2 of the gravity cage, and the rest is the same as in Embodiment 3. The medium-large opening and the adjacent medium-sized opening are combined to form two medium-large openings of about 60 square meters, and the height of the net 4 is about 9 meters.

[0047] The above-mentioned embodiments 2-4 are only several ways of arranging the frame structure 2 of the gravity cage, and the applicant is not limited thereto. The design is mainly based on comprehensive considerations of factors such as fish specifications, fish species, and requirements for mixed breeding.

[0048] The above is a detailed introduction to the utility model. Specific examples are used in this article to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
