Description

Technical Field

[0001] The utility model belongs to the technical field of deep-sea aquaculture equipment, and relates to a deep-sea aquaculture ship equipment and method, and specifically to a fish gathering and grading device suitable for aquaculture ship cabin aquaculture mode. 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. Aquaculture vessels can reach deep sea areas that ordinary aquaculture cages cannot reach, and have high economic and social value. The applicant currently operates the world's first 100,000-ton fully enclosed large-scale aquaculture vessel, which is currently the world's largest, most functional, most practical and most reliable deep-sea aquaculture equipment. The aquaculture vessel is equipped with several large aquaculture cabins. The aquaculture cabins are in the shape of a "wide-mouth bottle" with an octagonal cross-section. The water is exchanged with external seawater through a circulating water pump. The aquaculture water depth of each aquaculture cabin can reach 15m, and the number of adult fish raised can reach more than 100 tons. Using aquaculture vessels for fish farming can greatly increase fish production.

[0004] As an important form of aquaculture in modern marine fisheries, aquaculture in ship cabins is based on creating a suitable growth environment for marine organisms through swimming operations. However, aquaculture in ship cabins currently faces challenges in grading and compartment division, making it difficult to achieve effective operation, resulting in aquatic products growing in an unsuitable environment, which in turn leads to adverse consequences such as slower growth and increased mortality, which seriously restricts overall technological progress.

[0005] Grading and compartmenting are designed to meet the differentiated needs of marine organisms at different growth stages and types for their growth environment. However, in the closed shipboard cabin farming model, the large water surface, deep depth and large catch characteristics of the aquaculture vessels make grading and compartmenting work face huge challenges. The traditional dragnet grading method is not only labor-intensive and easy to damage the fish body, but also takes a long time to operate, which may cause the fish to be frightened for a long time or even die from lack of oxygen. Therefore, it is an urgent need to develop new and efficient grading and compartmenting operation methods to achieve mechanization and automation of fish catch improvement, minimize the impact of human factors on the production process, ensure high survival rate and no damage to the catch, and thus promote the healthy and sustainable development of large-scale aquaculture cabin farming models.

[0006] Patent CN208807378U discloses a device for sorting and driving fish in the breeding cabin of a breeding ship, which belongs to the technical field of fishery equipment. A track is fixed on the inner wall of the breeding cabin, and a guide wheel is provided on the side of the net frame. The guide wheel is connected to the track in a rolling manner. The net frame is fixedly connected to a steel wire rope. The driving device located on the inner wall of the breeding cabin drives the net frame to move in the breeding cabin through the steel wire rope. A fishing net is installed on the net frame. The effect is: the fish in the breeding cabin are sorted by size to ensure the breeding quality and control the number of fish; the middle net frame can be replaced with fishing nets with different mesh apertures to classify fish of different sizes, ensure the breeding quality, and at the same time reduce the probability of big fish eating small fish, and ensure the growth rate of young fish; when fishing, the farmed fish are driven to the side of the fish suction pump to increase the density of the fish school and improve the catching efficiency. However, the technical solution of this patent has many insurmountable shortcomings in actual application. First, the net rack is a rigid structure with large specifications. When not in use, it occupies a large space in the cabin and may cause harm to the organisms in the cabin. Second, there is a large water body distributed in the cabin in the longitudinal direction. The fish suction pump is only located at one point of the longitudinal water body. After the net rack drives the fish, only a small amount of fish is driven to the vicinity of the fish suction pump, making it impossible to effectively catch the fish. Utility Model Content

The applicant does not restrict the scheme for realizing the movement of the mobile net pulling assembly 2, that is, the cooperation mode between the walking mechanism and the track 3.

[0038] In this embodiment, when performing grading operations in the breeding cabin, the following steps are followed:

[0039] (1) Select a fish gathering net 7 with a suitable mesh size according to the fish grading specification requirements;

[0040] (2) Figure 3 As shown, the fixed net roll assembly 1 and the mobile net pull assembly 2 are both located at one end of the interface between the compartment area and the fish gathering and grading area. Figure 4-Figure 5 As shown, the walking mechanism is started, the driving gear 25 and the rack track are meshed with each other, and the mobile net assembly 2 moves along the rack track, driving the moving end of the fish gathering net 7 to move toward the other end of the interface between the compartment area and the fish gathering and grading area. During the movement, the net reel motor 11 is controlled to rewind the fish gathering net 7, and the fish gathering net 7 stretched between the fixed net reel assembly 1 and the mobile net reel assembly 2 is kept in a tensioned state. At the same time, in the area where the fish gathering net 7 has moved, sound, light, feeding and other fish luring methods are used to induce fish with a size smaller than the net mesh to pass through the fish gathering net 7 and enter the area where the fish gathering net 7 has moved, and the fish that meet the grading specification requirements are gathered in the compartment area, thereby realizing the fish grading operation in the breeding cabin 6.

[0041] (3) Figure 6As shown, the mobile drag net assembly 2 moves to the other end of the interface between the compartment area and the fish gathering and grading area. At this time, the fish that meet the grading specification requirements are gathered in the compartment area, thereby completing the grading operation.

[0042] like Figure 7 As shown, after the grading operation is completed in this embodiment, if the fish in the left breeding cabin 6 are to be separated into the right breeding cabin 6, the water level of the left breeding cabin 6 needs to be higher than that of the right breeding cabin 6, and the following structure is also required:

[0043] The fish conveying channel assembly 5 is used to connect the upper parts of the two breeding chambers 6, and includes a fish conveying pipe 53 connecting the upper parts of the two breeding chambers 6, and a valve 51 and a fry counter 52 arranged on the fish conveying pipe 53. The valve 51 is in an open state only when the compartments are divided, and the fry counter 52 can effectively count the number of fish in the compartments, which is convenient for refined management.

[0044] The compartment area is provided with a compartment assembly 4, which is used to compartment the fish classified by the fish gathering and grading device to another culture compartment 6 through the fish conveying channel assembly 5; the compartment assembly 4 includes a bottom net 43, a net-pulling rope 42 and a traction device 41, wherein the bottom net 43 is located at the bottom of the compartment area, and the bottom net 43 is traction-connected to the traction device 41 above through a plurality of net-pulling ropes 42 arranged at its outer edge. The traction device 41 pulls the bottom net 43 upward, and during the upward process, the fish are driven to the pipe mouth of the fish conveying pipe 53 and further transferred to the culture compartment 6 on the right.

[0045] Furthermore, the net-pulling rope 42 is made of nylon rope. The traction device 41 is made of a winch, which can be placed on a walkway in the culture cabin 6, or fixed to the inner wall of the culture cabin 6, or located on the top deck, and the applicant does not impose any restrictions. The applicant does not impose any restrictions on the selection of materials or components of the net-pulling rope 42 and the traction device 41, as long as the basic functions are met.

[0046] During the compartment division operation, the bottom net 43 is slowly raised by operating the winch, and the valve 51 on the fish conveying pipe 53 is opened at the same time. Due to the liquid level difference, the seawater in the left breeding cabin 6 overflows to the right breeding cabin 6. The seawater circulation pump of the left breeding cabin 6 must be always turned on to ensure that the liquid level of the left breeding cabin 6 does not drop. The bottom net 43 rises to the vicinity of the pipe opening of the fish conveying pipe 53, and is transferred to the right breeding cabin 6 under the force of the overflow of seawater, thereby realizing the compartment division operation after fish classification.

[0047] 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.
