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, in particular to a fishing gear for aquaculture ship 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. 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] Due to the large total weight of single-cabin aquaculture, the capture of adult fish is an important task of the aquaculture operation of the workboat. There are two main ways of catching fish in existing aquaculture workboats. One is to gather fish and catch them through large-scale purse seines. However, due to the huge size of the purse seines, the vertical depth is almost the same as the water height of the aquaculture cabin. Even with the help of a crane, a large number of people are required to participate, and divers are required to assist in supporting the net underwater, which is too labor-intensive. The second is to use divers to open a fishing net with a cross-sectional area equivalent to that in the cabin on the water surface, and then the diver drives the fishing net to dive and press the fish school down to the bottom near the fish suction pump. This method cannot guarantee the personal safety of divers.

[0005] Patent CN116195557A discloses a device and method for gathering fish on the aquaculture cabin of an aquaculture vessel, comprising a fish gathering net, a bottom lifting device, and an upper pulling device. The fish gathering net comprises a fishing net and a counterweight ring connected to the bottom of the fishing net; the bottom lifting device comprises: a steel wire rope passing through the counterweight ring, and the steel wire rope is pulled and lifted by a steel wire rope winch fixed on the bulkhead above the walkway; the upper pulling device comprises: a ground order fixed near the corner of the aquaculture cabin wall, a pulley block set on the ground order, an eye ring fixed on the bulkhead above the walkway, a net pulling winch set on the bulkhead above the walkway and located closer to the fish suction interface, a net-releasing rope and a net-pulling rope tied to the same position at the upper end of the fishing net at one end, and the other end of the net-releasing rope passes through the pulley block and the eye ring in turn, and is operated by an operator, and the other end of the net pulling rope passes through the eye ring and is pulled by the net pulling winch. This patent has few connection points on the aquaculture wall, simple process, and uses a short fish suction pipeline, resulting in small pipeline losses. However, the technical solution of this patent has many insurmountable shortcomings in actual application. First, the fish gathering net is too large, and its height is basically consistent with the depth of the aquaculture water in the aquaculture chamber. Whether it is manually or mechanically hoisted, the labor intensity is high, and it occupies a large storage space when not in use; second, the existing aquaculture chamber needs to be upgraded and renovated, and ground orders, pulley blocks, eye rings and other components need to be installed on the inner wall of the aquaculture chamber, which puts forward higher requirements on the corrosion and leakage prevention of the inner wall of the aquaculture chamber, and it is difficult to meet this demand with the current actual technical level; third, due to its design and installation method, it is necessary to use divers to tie one end of the net-laying rope and the net-pulling rope to the fishing net, pass the net-laying rope through the pulley, and then hand the net-laying rope and the net-pulling rope to the operator on the walkway. The operation is cumbersome and labor-intensive; fourth, the ground order will be full of shellfish, and divers need to be equipped to clean it regularly. Utility Model Content

[0006] In view of the above deficiencies in the prior art, the utility model provides a fishing gear for aquaculture ship cabin, which is suitable for the cabin environment of aquaculture ship, does not damage the original equipment structure, and has the characteristics of simple catching operation and high feasibility.

[0008] The utility model uses a deformable support component to achieve deformation by filling a medium inwardly and horizontally fits against the inner wall of the breeding cabin after deformation, thereby driving the net component to support the net underwater without the assistance of a diver.

[0009] As a preferred solution, the deformable support assembly includes an annular deformable bladder, a corner support sleeve is sleeved on the annular deformable bladder corresponding to the corner position of the inner wall of the breeding cabin, and a medium interface is opened on the annular deformable bladder. The corner support sleeve is set to achieve that the annular deformable bladder after being filled with the medium has the same shape as the octagonal breeding cabin and fits each other. Furthermore, the material of the annular deformable bladder is butyl rubber, natural latex rubber or thermoplastic polyurethane.

[0010] The utility model adopts two design schemes to achieve the utility model purpose, mainly in the type of net clothing components, one is a seine net, and the other is a lifting net.

[0011] As a preferred solution, the net assembly is a purse seine, including a net, several weight rings arranged at the bottom of the net, and a net-collecting wire rope running through all the weight rings, and the net-collecting wire rope is connected to a ship crane; when the purse seine is matched with a deformable support assembly, the medium that can be filled into the deformable support assembly is gas. The breeding ship is equipped with oxygen, nitrogen and other gas supply equipment, and the medium interface on the deformable support assembly can be connected to the corresponding gas supply equipment through a conveying hose and a pump. Therefore, the gas can be air, oxygen, nitrogen, and is not limited. As a preferred solution, the height of the net is 1 / 5 to 1 / 2 of the height of the breeding water in the breeding cabin.

[0012] As a preferred solution, the net assembly is a lifting net, including a net and a plurality of sinkers arranged at the bottom of the net; when the lifting net is matched with a deformable support assembly, the medium that can be filled in the deformable support assembly is gas or water. Water can be pumped out of waterproofing water or seawater in the cabin without restriction, and the medium interface on the deformable support assembly can be pumped out through a delivery hose or a pump. As a preferred solution, the height of the net is 1 / 5 to 1 / 2 of the height of the aquaculture water body in the aquaculture cabin.

[0013] As a preferred solution, a connecting ring is provided on the top of the corner support sleeve located at at least four corner positions, and a traction rope is provided on each connecting ring. The traction rope can be connected to other cranes on the ship. Further, considering the balance of forces, connecting rings can be provided on the top of the corner support sleeves at the corresponding four corners, six corners or all corners. In specific implementation, the connecting ring may not be provided, and the traction rope may be directly tied to the top of the corner support sleeve, the annular deformable capsule or the net, but the stability of these methods will be weaker than the connecting ring solution, and the applicant does not recommend but does not restrict this.
