Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a laver net drying frame as a material for seaweed cultivation.

(Prior technology) As a conventional seaweed net drying device,
A ``nori net drying float'' described in Publication No. 32687 is known.

(Problems to be solved by the invention) However, such conventional seaweed net drying floats have the following problems.

(1) When transporting the seaweed nets to the seaweed farms, the seaweed net drying floats were so bulky that it was not possible to carry the required number of nets on board the ship, which meant that the seaweed nets had to be transported back and forth several times.

(2) It was impossible for one person to do the drying work, so two people had to do it.

(3) In addition, seaweed net drying floats were vulnerable to stormy weather and sometimes fell over and were washed away.

(Means for Solving the Problems) The present invention was made to solve the problems of the conventional methods, and its purpose is to be able to carry large quantities on board a ship and go to the fish farm.
The purpose of this invention is to provide a laver net drying frame that can be easily carried out by one person, and will not fall over or be washed away even in the slightest of storms. A horizontal frame member with an elbow attached thereto, and a vertical frame member with a float attached to the middle of a vertical main made of FRP and a rope hanging device attached to the lower end of the vertical main,
A hanging rope fixing hole and a frame rope insertion groove are formed in the corner portion of the elbow, and the vertical frame member is configured to be detachably attached to the elbows attached to both ends of the horizontal main pipe.

(Function) Therefore, when drying a seaweed net using the seaweed net drying frame of the present invention, a horizontal frame member equipped with an elbow is attached to the bottom surface of the seaweed net, and the ears of the seaweed net are attached to the bottom surface of the seaweed net. The hanging rope attached to the hanging rope fixing hole of the elbow is hung with a hook provided at the tip, and the frame rope is inserted into the frame rope insertion groove. Next, a set rope is hooked to a rope hook provided at the lower end of the vertical main pipe, and the upper end of the vertical frame member is fitted into the elbow to float the seaweed net on the sea surface.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. The seaweed net drying frame A of this embodiment has a horizontal frame member 3 with elbows 2, 2 provided at both ends of a horizontal main pipe 1, a float 5 attached to the middle of a vertical main pipe 4, and It is comprised of vertical frame members 7, 7 with rope hooks 6 attached to their lower ends.

Next, each of the above configurations will be explained.

First, as shown in FIG. 2, the horizontal main pipe 1 includes a coating layer 8a made of synthetic resin such as polyvinyl chloride, polyurethane, ABS, etc., an FRP layer 8b made of glass fiber reinforced plastic, and a coating layer 8b made of polyvinyl chloride, polyurethane, ABS, etc. It is formed into a three-layered FRP composite tube 8 consisting of a core layer 8c made of synthetic resin such as polystyrene or ABS, and locking rings 9, 9 are attached at a required interval in the center. The length of the horizontal main pipe 1 is the distance between the set ropes 10, 10 (approximately
3.4m to 3.8m) is standard.

Also, the vertical main pipe 4 is similar to the horizontal main pipe 1 described above.
Formed into FRP composite pipe, its length is 1m to 1.5m
is formed.

Next, the elbow 2 is inserted into the pipe body 2 as shown in FIG.
a and 2b are arranged at right angles, a reinforcing plate 2c is provided at the corner, and a hole 1 for fixing the hanging rope is provided in this reinforcing plate 2c.
1 and a frame rope insertion groove 12 are formed, and the material is synthetic resin such as ABS, AES, PVC, FRP, etc., and the fitting dimension with the horizontal main pipe 1 and vertical main pipe 4 is 30 mm to 100 mm. is formed.

Next, the float 5 is formed into a substantially cylindrical shape, and has a through hole 5a on its axis through which the vertical main pipe 4 passes, and at both end openings of the through hole 5a,
Flange members 13, 13 made of synthetic resin such as PVC, PS, PE, ABS, etc. are fitted. The float 5 is made of copolymer foam of PE and PS resin,
Use a material with higher breaking strength than foam made from PS resin alone.

Next, the rope hanging device 6 has one end formed with a fitting part 6a with the vertical main pipe 4, and the other end formed with a rope hanging pipe part 6b.
It has a structure in which several rope hooks 14 are formed at equal intervals around the outer periphery of b.

In addition, in the rope retaining groove 14, three stages of retaining holes 14b, 14c, and 14d for large ropes, medium ropes, and small ropes are formed in order from the opening 14a side, and the rope retaining tube portion 6b There are two types of grooves, one in which two lines are formed in one direction (Fig. 5) and one in which four lines are formed in two directions (Fig. 6).

A stopper 15 made of natural rubber, synthetic rubber, plastic, or the like is fitted to the upper end of the vertical main pipe 4 to prevent seawater from flowing into the vertical main pipe 4.

To assemble the drying frame A of this example,
Fit the elbows 2, 2 on both ends of the horizontal main pipe 1,
Assemble the horizontal frame member 3. In this case, horizontal main 1
is glued and fixed into one pipe body 2a of the elbow 2, a through hole is formed in the horizontal main pipe 1 from the pin hole 16 formed in the elbow 2, and a pin is driven into this to form a retaining structure. . Then, a frame rope 18b for fixing the seaweed nets 17, 17 is placed between the locking rings 9, 9 at the center of the horizontal main pipe 1 of the horizontal frame member 3 assembled as described above, and this is tied with the string 19. At the same time, tighten the elbows 2, 2 at both ends of the horizontal main pipe 1.
Attach the hanging rope 2 to the hanging rope fixing hole 11 in the corner part 2c of
0, attach a hook 21 to the end of this hanging rope 20, and attach this hook 21 to the ear rope 17 of the seaweed net 17.
Furthermore, the frame ropes 18a, 18c on both sides of the seaweed net 17 are inserted into the frame rope insertion grooves 12, 12 of the elbows 2, 2, respectively, and the frame ropes 18a, 18c are tied to the elbows with strings 22. A horizontal frame member 3 is attached to the lower surface of the seaweed net 17 to float it on the sea surface of the seaweed farm.

Also, a rope hook 6 is fitted to the lower end of the vertical main pipe 4, and a stopper 15 is inserted into the upper end of the vertical main pipe 4. Next, the vertical main pipe 4 is inserted into the through hole 5a of the float 5. by inserting the float 5 into the vertical main pipe 4.
The vertical frame member 7 is assembled by fixing it at an appropriate position with a rubber band 23 or the like.

When drying the seaweed net 17, the vertical frame member 7 assembled as described above is loaded onto a ship and transported to a seaweed farm, where the ropes of the rope hooks 6 are attached to the set ropes 10. Latch groove 14
, and then, while fitting the upper end of the vertical main pipe 4 into the elbow 2 of the horizontal frame member 3,
One by one, the seaweed net 17 is lifted out to dry.

When the drying of the seaweed net 17 is completed, the rope hook 6 is removed from the set rope 10, the upper end of the vertical main pipe 4 is removed from the elbow 2, and the vertical frame member 7 is removed.

Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration of the present invention is not limited to the embodiments described above.

For example, in the example, the horizontal main pipe and the vertical main pipe are formed as FRP composite pipes with a three-layer structure, but they are not limited to this. They may also have a two-layer structure with an FRP layer and a covering layer, or a single pipe with only an FRP layer. But that's fine.

(Effects of the invention) As explained above, the nori net drying frame of the present invention is easy to transport to the nori farm, and can be easily carried out by one person. When attaching or removing the set rope from the drying frame, it is easy to work and can be done in a short time, so it can be used as a rational drying frame and has practical effects.
