Abstract

PROBLEM TO BE SOLVED: To provide a culturing fish preserve having improved durability, capable of facilitating checking and repair, maintenance, exchange of parts, or the like, capable of reducing the labor and having an inexpensive production cost. SOLUTION: This culturing fish preserve is obtained by utilizing the buoyancy of a hollow pipe itself, simplifying the structure by constituting the body by using the strength and the durability of the cylindrical pipe, and simplifying and normalizing other parts to decrease the cost and to reduce the labor for maintenance.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combination of a characteristic of a vinyl chloride pipe and a corrosion-resistant steel material, a standardization and minimization of parts to be used, and a minimization of processing steps.

[0002]

2. Description of the Related Art Bamboo on a Styrofoam float,
They are framed with wood or the like and tied with rubber ropes or wires, or steel pipes are assembled and welded to perform rust-preventive painting.

[0003]

The conventional aquaculture cages have a short durability of 2 to 3 years, and even within 5 years of frequent care, and because the parts are not common, they are produced on the spot. In the case of steel, there was a problem that welding painting was carried out on the sea or welding painting near the waterside, moving to the sea with a crane and towing to the installation location.

A structure in which a thick vinyl chloride pipe is used as a main constituent member to minimize vertical movement by waves as much as possible, has sufficient strength against external forces such as waves, and has excellent corrosion resistance and durability. Metal parts are standardized, commonized and replaced easily, which further improves durability, and anyone can assemble and disassemble on the sea or ship using only a wrench,
It is intended to be inexpensive.

[0005]

SUMMARY OF THE INVENTION Corrosion resistance to weight,
Considering the durability, strength and flexibility, it is considered that resin is the best, and it can be easily welded in it. Vinyl chloride is used as a tube, and it is used by welding all together with the connection part. It is more effective to process VP pipes for water supply and refueling which are less expensive and have no problem in strength.

The VP tube has a fixed length because it is a mass-produced product.
Divide and fix by welding, and fix the divided portion with a corrosion-resistant stainless steel plate for column reinforcement.

[0007] In order to maintain buoyancy in the event of breakage due to any cause, such as breakage due to drifting objects, ships, or accidents during work, and to facilitate assembly at sea, connecting PVC pipes Adhesively seal the part with the same material.

[0008] A rubber packing is inserted into the connecting portion in order to adjust the length variation of the PVC pipe, prevent welding for a long time in seawater, and facilitate repair and replacement.

The support column is formed by bending a single corrosion-resistant stainless steel bar and tightening only with nuts, avoiding welding, drilling and bolting, and fixing it in a triangular shape when viewed from the front and side. Reduce excess stress, ensure sufficient strength, and maintain corrosion resistance.

Since the mesh fixing pipe is passed through without fixing, any material can be used as long as it can withstand the load of the net, but it is better to use a vinyl chloride pipe in terms of durability and strength. In addition, it should be removable at an appropriate position in consideration of repair and replacement.

[0011] Depending on the type of fish to be cultured and the location of the fish, the size of the culture cage and the environment in which it affects will differ. To deal with this, the corner pipe and the outer periphery are reinforced with corrosion-resistant stainless steel bars.

In addition, the same pipe as that of the main body is used, and the support pipe is not attached to the support pipe. The support pipe is not attached and the extension pipe is attached to the corner pipe. The outer circumference is reinforced and the connection is made with corrosion-resistant stainless steel connection fittings. Let it.

[0013] The corrosion-resistant stainless steel fitting is provided with a pipe for protecting the screw, and the corrosion-resistant stainless steel fitting is passed through the pipe.

The corrosion-resistant stainless steel connection fitting is also used as a connection fitting when a fish cage is installed in parallel.

In the case where the shape of the cage is made hexagonal, it is the same as just changing the angle of the corner pipe portion to one having an angle of 120 °.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG.
FIG. 1 is an overall configuration diagram in which a corner pipe 4 is connected to a supporting column 2, a fixing net fixing pipe 1 is passed through a support 2, and a net 5 is fixed.

The flanges for fixing the columns other than the connecting portion are shown in FIG. 2. The flange 6 is resin welded at the factory, the reinforcing plate 7 and the bolts 8 are attached in advance, and the entire PVC pipe is assembled at the site. After the end, the support 2 is assembled.

In FIG. 3, the connecting portion is a plate 10 made of the same material as the pipe.
Is fixed to the pipe at the factory, and the packing 9 is assembled when connecting the PVC pipe. Attachment of the column (2) is the same as the previous section.

After the PVC pipes have been assembled around the entire circumference and the columns 2 have been fixed, they are passed through a net fixing pipe 1 and joined at a suitable position with a water supply joint.

Replacement of the outer peripheral bolt of the connecting portion of the vinyl chloride pipe with the connecting bolt is fixed with two bolts, as shown in FIG. Of the pipe 11, the fitting 12 for the connection, and the fixing with the double nut 13.

When the reinforcing frame is attached, the corner pipes are shown in FIGS.
Is connected at the end, and the length and position are adjusted with the extension bolt 20 and fixed.

[0022]

Since the present invention is configured as described above, the following effects are produced.

The main component is a vinyl chloride pipe,
There is no need for painting, the durability against seawater is improved, and the removal of deposits such as wisteria can be easily performed.

Furthermore, the sizes are unified, and they are compatible and easy to handle irrespective of the size and shape of the cage.

[0025] The shape and form can be freely configured and adapted to the differences in cultured fish and the environment, and anyone can use a wrench alone without any qualifications or licenses.

The number of parts for maintenance, inspection and repair / replacement is small.
Standardization makes it easy and cheap.
This further improves the durability.

It is inexpensive by pursuing as few parts as possible, standardization, and reduction in the number of processing steps.
