Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to cages used in aquaculture and fisheries, and makes it possible to perform aquaculture work smoothly in any of the sea surface, undersea, and undersea without distinction between the inland sea and the open sea. It relates to an all-sea-type aquaculture cage that can be carried out and has excellent economic efficiency, such as requiring a small amount of special equipment and facilities on the sea.

[0002]

2. Description of the Related Art Conventionally, all of the aquaculture industry is marine aquaculture, and the reason for this is that there are only cages that can be aquaculture only on the surface of the sea. Therefore, a closed sea area such as an inland sea where the waves are quiet or an inlet was a condition for a suitable aquaculture. However, this idea is basically wrong,
When a large amount of fish is cultivated in such a closed sea area, the occurrence of marine pollution and fish diseases cannot be avoided, and currently, aquaculture fisheries are caused by such basic mistakes that the occurrence of red tide due to marine pollution occurs. In fact, many problems such as damage to cages due to typhoons and mass mortality due to the outbreak of fish diseases are caused. In the future, in order to continue and develop aquaculture, it is time to make a transition from the closed sea area to the open sea, and from the sea level to the undersea. Need aquaculture cage that can also be used.

[0003]

However, all the sea-surface type cages currently used are lantern-type cages suspended from a raft, and the structure is flexible, but the entire sea area including the seabed The mold cage must have a rigid structure with a basic structure. The reason is that when placed on the seabed, the shape of the cage must be maintained. In addition, weight is necessary to maintain stability as well as strength to withstand fast tidal currents. The present invention has been made in view of these points, to provide an all-sea-type aquaculture cage that enables aquaculture in any sea area such as the sea surface, the sea, and the sea floor without distinction between the inland sea and the open sea. It is intended.

[0004]

In view of the above, the present invention constitutes a cage main body composed of an appropriately shaped three-dimensional frame, and the outer peripheral surface of the cage main body is covered with a multiplicity of small hole constituents such as a wire net, and the cage main body is formed. A hollow body is used for a part or all of the structural material of this, and the cage main body has a rigid structure with the same rigid frame structure as the architectural design, and the weight of the cage main body is an appropriate weight by utilizing the buoyancy of the structural material of the hollow body. It was adjusted to. In some cases, a titanium wire mesh is used as the multi-hole structure such as the wire mesh.

As the structure of the cage, there are columns, floor beams, ceiling beams,
Although it is composed of nets and legs, the main structure of the cage is that the floor beams, columns, and ceiling beams require structural strength. The average size of the cages currently used is about 10m x 10mx 8m, but this is the case of sea cages. In this case, the fish gather at the bottom of the cage as a habit, so in the case of submersible aquaculture, A depth of about 5 m is sufficient. Therefore, when the structural strength of the cage is calculated as 10m x 10m x 5m, the total weight is about 7-
This is a calculation that requires 8 tons. The larger the volume of the cage is, the higher the efficiency of cage cultivation is. Therefore, the size of the cage tends to be large. In the future, it will be necessary to request a cage of 12m or 15m. It is thought that it will inevitably increase.

In the case of submarine or submarine aquaculture, which is different from the current marine aquaculture, feeding and picking work are performed on the sea. In that case,
It is necessary to raise the cage to the surface of the sea each time, and in order to raise the cage that is 7-8 tons, and in some cases 10 tons or more, the equipment on the sea is necessary for that. The equipment for such pulling up costs a lot of money and is not preferable in terms of economy. From such a viewpoint, this cage uses a hollow material as the material used for the structural portion. The material is steel, aluminum alloy, reinforced resin, etc., but depending on the type of fish to be cultivated, an appropriate water depth will be selected, and in some cases 50 m
It requires more depth, but it must also be able to withstand water pressure.

Therefore, the design of this cage is based on the following conditions. (1) Area and volume of cage (2) Lifting force (winch capacity) (3) Weight of cage and buoyancy calculation (4) Depth of installation. For example: (1) 10m x 10m x 5m (2) 800kg (winch on board, hoisting capacity 2 ▲ ton ▼) (3) 8000kg (gross weight) 7200kg (buoyancy) (4) 70m 7 atm or more (withstand pressure of hollow material) or more Design the structure based on the settings such as. In this case,
In order to lower the center of gravity of the cage in consideration of the stability of the cage, the buoyancy is calculated to be applied to the upper ceiling beam, and if the ceiling beam alone does not produce the buoyancy, the column or the entire structural part Try to take.

[0008]

The function of the aquaculture cage of the whole sea area type according to the present invention is as follows.
Basically different from the sea cages currently used, the structure itself is made into a rigid structure, and the weight of the cage itself due to rigidity is utilized by using the buoyancy by using the hollow material in the structure part, the weight of the cage It is possible to freely adjust the structure of the cage, and it is possible to take sufficient structural strength of the cage, and the weight increase due to the strength will increase the buoyancy at the same time. It can be used for larger cages.

[0009] In claim 2, a large number of small hole constructions such as a wire net covering the outer peripheral surface of the fish cage body are used. The reason is that the titanium wire net has absolute corrosion resistance to seawater, and the net of the cultured fish cage is However, there is a problem in terms of abrasion resistance, and when it is rubbed by waves or ocean currents, it may wear, which was the only problem. However, in the sea cages that have been used up to now, since the wire mesh itself also needs flexibility, the welded wire mesh cannot be used because there is a concern that it will break due to the burden on the welded part. However, in the present invention, the point structure is a rigid structure with high strength, and since the wire mesh itself is also fixed to the frame, it is not rubbed,
Welded wire mesh, which completely eliminates the friction caused by the contact between mesh wires, is more advantageous.

The diameter of the titanium wire used for the welding wire mesh is 3 m.
Around m is most effective from the viewpoint of wire strength, welding strength and economics. 40m depending on the purpose of use of mesh
The m-square position is ideal from the viewpoint of wire mesh strength. Due to its structure, the all-sea cage is inevitably more expensive in terms of price compared to the ocean cages that have been used up until now, but durability is required, and the cage structure and the net strength Durability is also important. For that purpose, a titanium welding net is the most ideal.

EFFECTS OF THE INVENTION Conventionally, the only form of cage culture has been sea surface culture in which fish are grown on the sea surface, and there has been no alternative culture method at present. As a result, the current aquaculture industry continues with various problems. The only solution to drastically reform the aquaculture industry is the development of cages that can be used in all weathers and waters, and the present invention makes it possible. The feature of the present invention is that it is possible to avoid the weight that is inevitably increased by increasing the structural strength by utilizing the buoyancy of the hollow steel material, and the structural portion is dip coated with plasticized PVC to make it possible to use seawater. It is completely waterproof and corrosion resistant. With the development of this cage, it will be possible to carry out aquaculture according to the type of fish and the habitat environment in the future, so it will be possible to produce fish with a superior quality comparable to natural fish and it will affect the aquaculture industry. The profits are immeasurable.

According to the second aspect of the present invention, abrasion is eradicated by adopting the titanium-made welded wire mesh for the abrasion resistance, which is the only weakness of the titanium mesh used for the cage body by providing the structural strength. It is something you can do.
