Abstract

(57) [Summary] Fish aquaculture equipment [Purpose] To safely moor the aquaculture equipment regardless of whether the weather is clear or stormy. [Structure] A plurality of cages 12 are arranged around a tower-shaped floating body 11 that penetrates the sea surface vertically. The fish tank 12 has a float 34 whose buoyancy can be freely adjusted. The buoyancy of the float 34 is adjusted by the flotation means to float and sink the same cage 12 along the floating body 11. The floating cage 12 and the submerged cage 12 are each moored to the floating body 11 by mooring means.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to fish farming equipment.

0002

[Conventional technology]

Conventionally, this type of equipment has been put into practical use in Northern Europe, as shown in Figure 4. It is a so-called "ship-shaped cage" and has a boat-shaped outline and multiple cages. A floating body 42 of a sturdy steel structure with a cage window 41, and a floating body 42 fitted into the cage window 41 respectively. More than 43 cages are known to exist.

0003

[Problem that the idea aims to solve]

For example, with the above equipment, the waves are calm in the summer, so the equipment may be placed in a wide offshore area. By mooring the fish and moving it to inland seas in winter to avoid rough weather, the operation and management of aquaculture can be made more effective. Although it has the advantage of being easy to move, the reality is that moving equipment is difficult. It's hard work. In addition, since the entire floating body 42 and the fish tank 43 are near the sea surface, There is a problem in that it is difficult to moor equipment due to waves and currents.

0004 The purpose of this invention is to provide fish farming equipment that solves the above problems. .

[0005]

[Means to solve the problem]

The fish farming equipment based on this idea consists of a tower-shaped floating body that penetrates the sea surface up and down, and a floating Multiple cages with floats placed around the body and with adjustable buoyancy; A flotation means that adjusts the buoyancy and floats and sinks the same cage along the floating body, and a cage that is in a floating state. The system consists of a mooring means for mooring a suspended and submerged cage to a floating body, respectively. be.

[0006]

[Effect] The fish farming facility based on this idea is equipped with a tower-shaped floating body that penetrates the sea surface up and down. Because of this, the floating body is less susceptible to the effects of waves and currents.

[0007] Furthermore, the equipment has floats that are placed around the floating body and whose buoyancy can be adjusted freely. When using multiple cages, the buoyancy of the floats can be adjusted to raise and lower the same cage along the floating body. Since it is equipped with a sinking means, you can float the fish tank on sunny days, etc. The buoyancy of the cage stabilizes the floating body, and in times of stormy weather, the cage can be lowered to make it more stable. Kesu is not easily affected by waves or currents.

[0008] In addition, mooring systems are used to moor floating cages and submerged cages to floating bodies. Because it is equipped with a retaining means, the movement of the fish tank due to waves and currents is small.

[0009]

【Example】

An embodiment of this invention will now be described with reference to FIGS. 1 to 3.

0010 Fish farming equipment is used as a control tower and penetrates the sea surface up and down. A hollow tower-shaped floating body 11 and four cages 12 placed around the floating body 11. It is equipped with

[0011] The top surface of the floating body 11 is a deck, which is equipped with handrails 13 and marker lights 14. There is. Although not shown, a hatch is provided on the deck, and a hatch is provided inside the floating body 11. There is a passage connecting the battery room and food storage to the hatch. On the underside of floating body 11 is provided with a hanging strut 15. At the lower end of the pillar 15 are four cage windows 16 and A mooring frame 18 having four radial arms 17 that partitions these sections extends horizontally outward. Sea urchins are provided. In addition, a reinforcement bracket is installed to span strut 15 and arm 17. 19 are provided. Floating body 11, strut 15 and mooring frame 18 are made of sturdy steel pipes or steel boxes. It has a rigid structure. An eye plate 21 is installed at the tip of each of the four arms 17. Each eye plate 21 is connected to the seabed with a mooring line 23 via a shackle 22. being admired.

0012 Fish tank 12 consists of a closed box-shaped mesh cage 31 and the vertical and horizontal ridges of cage 31, excluding the top surface. The rope 32 that is wired in Rinaru. Although the ceiling of Kakoi 31 is not shown in detail, it is removable. The movable frame 33 is , is formed in a shape to fit into the cage window 16 of the mooring frame 18, and has a plurality of It is formed by connecting two steel pipes. The movable frame 33 is empty at multiple locations. A float 34 is provided whose buoyancy can be freely adjusted by letting air in and out.

[0013] FIG. 2 shows the cage 12 in a floating state. In this case, Kakoi 31 The rope 32 on the lower peripheral edge of the mooring frame 18 is secured to the mooring frame 18. Shake in fish tank 12 is slight.

[0014] FIG. 3 shows the state in which the fish tank 12 is submerged. 12 cages during surfacing By reducing the buoyancy and attaching a weight 35 to the bottom of cage 12, cage 12 will sink and the cage window will open. Fish tank 12 fits perfectly in 16. Then, only floating body 11 can be seen on the sea surface. Therefore, the wave force does not act on either the mooring frame 18 or the mooring frame 33, improving wave resistance. That means that. In addition, when the vessel sinks, an automatic feeding machine feeds from floating structure 11 to cage 12. Just do it like this. Furthermore, since there are few organisms attached to cage 12 in the submerged state, , no additional network is required, but administrative monitoring may be necessary.

[0015]

[Effect of the idea]

According to this idea, the floating body is less susceptible to the effects of waves and currents, and can be easily used in stormy weather. If you let it sink, the fish tank will be less affected by waves and currents, so there will be less movement. , has excellent wave resistance and tidal current resistance, and therefore has low drifting force and can be safely moored even in rough weather. Aquaculture facilities are provided that allow for

[0016] Furthermore, on sunny days, if the fish tank is floated, the buoyancy of the floats will cause the floating bodies to float. It is stable and the shake of the cage due to waves and currents is small, so it can be used even when affected by waves. However, the aquaculture equipment can be safely moored.
