Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to fish and shellfish farming or aquaculture facilities, and more specifically to improvements in fish cages.

[Conventional technology]

Conventional fish cages are installed far offshore from the coast, and are equipped with numerous floats to prevent the fish pens from sinking.Additionally, to prevent the fish pens from being washed away by ocean currents, weights are placed on the seabed and tied together with mooring ropes. .

Usually, a group of fish pens is formed by arranging a plurality of such facilities at predetermined intervals.

However, such conventional fish cages are suspended on the sea with many floats arranged around them, making it difficult for fishing boats to approach and work on them. It was dangerous to get close to them, and there were safety issues.

Furthermore, the work of storing and removing fish and shellfish from the fish tank has to be carried out from a fishing boat far away from the fish pen, which is a complicated work to be carried out on a moving fishing boat.

Usually, one type of fish and shellfish is often housed in one fish tank, and therefore, in order to house a large number of fish and shellfish, a large number of fish cages must be installed on the sea surface. This required a wide sea area for fishing boats to navigate around the fish preserves.

In addition, since it was installed offshore, it had to be transported back and forth from the quay by boat, which was unfavorable in terms of time and economy, and there was a risk of it being washed away or damaged in stormy weather.

Furthermore, it was a difficult task to move the fish cages, which were tied to the ocean floor via numerous ropes.

[Purpose of invention]

The present invention solves the above-mentioned problems with conventional fish cages, and can be installed at high density along the quay or in a size that matches the shape and size of the quay. It simplifies installation work and takes out fish and shellfish from fish pens, and it also makes it possible to walk from the coast to the worksite without using a boat, and allows fishing boats to come alongside to increase work safety. The purpose of this project is to provide a farm facility that can be moved to a safe location without fear of being washed away or damaged even in the event of marine pollution such as red tide.

[Structure of the idea]

The present invention aims to achieve the above object by driving a plurality of piles at predetermined intervals on the seabed near the coast, and placing prestressed concrete blocks with a square cross section and a rectangular plane between the piles. Floating bodies are arranged in the longitudinal direction facing offshore so that they are guided by the piles via mooring fittings, and there is a gap between rows of opposing floating bodies, and fishing boats are moored on the surface of the sea outside these floating bodies. A net-like fish tank is movably supported along rails provided at the edges of the opposing floating bodies, and a bridge is provided to connect the shore and the end of the floating body closest to the shore. It is characterized by the fact that

That is, the present invention arranges a net-shaped fish tank supported by the floating bodies in the water between the floating bodies, and further connects the shore with the end of the floating body closest to the shore by a bridge. Because of the structure, it is possible to walk to the workshop from the coast without using a boat.

The floating bodies mentioned above are made of rectangular prestressed concrete, so they have excellent strength and durability.Also, each floating body is manufactured to match the size of the fish tank, so each floating body can be used as a separate fish cage. It is possible to store different types of fish and shellfish in individual fish cages.

In addition, rails are attached to the opposing edges of the floating body, and the net-shaped fish cage is supported so that it can be moved along the rails. The fitting and installation can be completed in a state where the fish cages are gathered together in a small size, and then the fish cages gathered in a small size can be pushed out to the other end of the rail, so the installation work is easy. Furthermore, when taking out the fish and shellfish in the fish tank, the fish and shellfish can be collected in one place by manually moving the fish tank to the end of the rail, making the work of taking out the fish and shellfish easy.

Furthermore, the spacing between the floating bodies is determined by driving stakes according to the width of the fish cage, and these stakes are engaged with the mooring metal fittings so that they can move up and down, so the floating bodies can be easily adjusted to the vertical movement of the sea surface due to low tide. They never come into contact with each other.

Furthermore, since fishing boats can be moored on the surface of the floating body, safe unloading and shipping operations can be carried out.

The net-like fish cage installed between the floating bodies has an upper part or an opening removably attached to the floating body, and a number of sinks are attached to the lower part of the fish cage so that the fish cage hangs down into the sea. ing.

A series of farming facilities formed by arranging floating bodies, fish pens, and floating bodies in this order can be further arranged in multiple rows to form a large-scale facility.

〔Example〕

Next, an embodiment of the present invention will be described with reference to FIGS. 1 to 5.

The breeding facility 1 is composed of a plurality of floating bodies 2, a fish cage 10 interposed between these floating bodies 2, and a pile 8 for mooring the floating bodies 2.

The floating body 2 has a composite structure with excellent corrosion resistance, using steel for the interior and prestressed concrete for the exterior.As shown in Figure 3, the floating body 2 has a structural material 3 and a space 4 inside. The entire structure is watertight.

When the floating body 2 is floated on the water surface, the height from the water surface to the upper surface of the floating body 2 is set to be the most suitable height for the fishing boat 12 to come ashore.

Access bridges 5, 6, and 7 are provided at predetermined intervals between these floating bodies 2 and between the floating bodies 2 and the quay F. Further, rails 20 are attached to opposing edges of the floating body 2, and a temporary fixing member 21 at the upper end of the fish cage 10 is fitted to the rail 20, so that the floating body 2 is supported movably along the rail 20. This fish tank 10
When attaching to the rail 20, the fitting and attachment is completed with the fish cages 10 gathered together in a small size on one end side of the rail 20, and then the gathered fish cages 10 are pushed out to the other end side of the rail 20. Further, when taking out the fish and shellfish in the fish tank 10, the fish and shellfish are collected in one place by manually operating the fish tank 10 at the end of the rail 20 and taken out. A sink 1 with a net-like fish cage 10 attached to its lower end
suspended in water by a weight of 1.

Since the fish tank 10 is installed so as not to be carried away by ocean currents as described above, there is no need to arrange mooring ropes on the seabed around the fish tank 10, so the floating body 2 can be moored on the open sea surface, making it safe and easy to operate. becomes easier.

The piles 8 are placed on the seabed G so that they are located at both ends of the floating body 2.
At the same time, the mooring fittings 9 provided at both ends of the floating body 2 are attached.

As shown in FIG.
3 is fixed to one end of the mounting member 14, and the other end is attached to the other mounting member 14 via a removable shackle 15 so as to loosely surround the pile 8.

Therefore, not only can it be easily attached to and detached from the pile 8, but it can also be slid against the vertical movement of the floating body 2 due to the rise and fall of the tide level.

A bridge 7 is installed between the coast F and the end of the floating body 2 closest to the coast F. The shape and material of this bridge 7 are not particularly limited, but it is preferable that it has a width and strength that allows luggage etc. to be transported, and that it can be easily removed.

In the farm facility 1 configured in this manner and having a plurality of fish pens 10, different types of fish and shellfish are farmed in separate fish pens 10 for each type.

In this embodiment, a composite material made of steel and prestressed concrete is used as the material for the floating body 2, so it has excellent corrosion resistance and requires almost no maintenance. Furthermore, since a large space is formed inside the floating body 2, there is an advantage that it can be used for multiple purposes as a storage space for equipment and the like.

[Effect of idea]

As described above, the farming facility according to the present invention is characterized in that a net-like fish tank is provided between a plurality of floating bodies provided via mooring devices, and a fishing boat can be moored. The following effects can be achieved.

A floating structure has been installed that allows fishing boats to dock, allowing for safe unloading and shipping operations.

Because fish pens can be arranged at high density along the quay, relatively large-scale fish farming facilities can be easily set up even in narrow harbors.Furthermore, since the floating structure can be accessed directly from land, it is safe and quick. Various tasks are possible.

Since the fish cage is installed near a quay where there are few waves and is supported by a floating body, there is no risk of the fish cage being washed away or damaged. In addition, since it is not moored to the seabed with a mooring rope, fishing boats can approach it, making movement easier, safer, and easier to work with.

Since the fish tank was attached to the floating body via rails,
This makes it easier to install fish cages and take out fish and shellfish from fish cages. Since it can be quickly detached from the mooring device, it can be easily moved to a safe location even if seawater pollution such as red tide occurs.
