Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for lightly draining the seaweed net, which is set especially for raising seedlings, in the floating seaweed culture, manually.

[0002]

2. Description of the Prior Art In floating nori culture, the nori net is dried on the sea surface during seedling raising. As a conventional nori net drying device, for example, floats are formed on the lower sides of both sides of a generally U-shaped pipe. Were fixed and arranged at substantially equal intervals on the sea surface, the upper ends of the pipes were fixed by ropes, and the lower parts were fixed by different ropes, so that columns were formed standing on the sea surface. Then, the nori net was placed between the columns, and the nori net was stretched on the sea surface by inserting rings provided on both sides of the nori net at substantially equal intervals into the columns. In this device, by lifting all the rings by hand and locking them to the protrusions provided on the upper ends of the columns,
The nori net is designed to be drained from the surface of the sea.

[0003]

However, in this conventional seaweed net drying apparatus, the seaweed net is dried by manually lifting the rings one by one and locking the rings to the protrusions at the upper ends of the columns. Therefore, a large number of seaweed nets (usually 4
There was a problem that it would be very hard work to drain all 0 sets). Also, when the seaweed buds are small, the drying time is as short as about 30 minutes, so the drying and soaking work overlap and it is difficult, and there is the problem that if the sea suddenly rushes, it will not be in time. .

The present invention has been made in order to solve the above-mentioned conventional problems, and the purpose thereof is to make the pulling force of the drying rope effectively act as the rotating force of the supporting column and The present invention is to provide a floating aquaculture laver net drying apparatus capable of lightly draining the whole seaweed net at the same time and completely immersing the seaweed net in the sea.

[0005]

[Means for Solving the Problems] As means for achieving the above-mentioned object, in the device for draining floating nori seaweed net according to claim 1 of the present invention, a floating seaweed nori net is stretched below the sea surface,
And a device for placing the lower surface of the seaweed net and simultaneously withdrawing the entire surface from below the sea surface, wherein columns are provided at both ends of the horizontal horizontal rods arranged on the lower surface side of the seaweed net, and are substantially orthogonal to the columns. A drainage frame provided with a vertical and horizontal rod at the lower end of the pole when the prop is erected on the surface of the sea and oriented toward the direction in which the nori net is stretched; a float attached to the prop of the drought frame; A fixing rope for connecting the upper end portions of the drooping frames arranged at predetermined intervals over the entire length of the above; and for connecting the tip end portions of the vertical and horizontal rods with one end fixed to one of the ABA frame ropes, and A draining rope having the other end fixed to the connecting rod; and a pulling rope that fastens the connecting rod and the other ABA frame rope via a pulley.

According to a second aspect of the present invention, there is provided a floating aquaculture laver net draining apparatus according to the first aspect, wherein the horizontal horizontal rod is formed in a substantially concave shape. It is configured to be rotatably supported by a column.

[0007]

According to the floating aquaculture nori net drying apparatus according to the first aspect of the present invention, since the vertical and horizontal rods of the drying frame are substantially orthogonal to the supporting columns because of the above-mentioned structure, the supporting columns are laid down sideways. When is dipped in the sea, the rope for draining is in a state in which the end portions of the vertical and horizontal rods that are oriented substantially downward are connected to each other. Since the support column rotates around the connection point position of the fixing rope as a fulcrum, in this case, the pulling force of the drying rope directly acts on the support position at a position separated from the rotation center of the support column by the length of the vertical and horizontal rods. It becomes the force to rotate. Therefore, the pulling force of the drying rope exerts the maximum rotating force at the time of draining the laver net, and the laver net can be efficiently dried with a small force.

According to the floating aquaculture laver net draining apparatus of the second aspect, since the horizontal horizontal rod arranged on the lower surface side of the laver net rotates because of the above-mentioned configuration, the horizontal horizontal rod is always downward regardless of the posture of the supporting column. It becomes concave. Therefore, when the nori net is immersed in the sea with the props lying down, the horizontal horizontal rod will be submerged in the water by the pressure of the nori net even if the props float on the water surface. To be done.

The horizontal horizontal rod 10 is arranged on the lower surface side of the seaweed net 5 in the horizontal horizontal direction, and has both ends formed on the horizontal shaft portions 13 and 13 and between the horizontal shaft portions 13 and 13. Is formed with a horizontal step portion 14 having an appropriate size and a concave shape. Rotation rings 13a for fixing the fixing ropes 3 are attached to both ends of the horizontal shaft portions 13 and 13, respectively.

The stanchions 11 are arranged on both sides of the seaweed net 5, and have at their upper ends a shaft supporting portion 15 for rotatably holding the horizontal shaft portion 13 of the horizontal horizontal rod in an orthogonal state. .

The vertical and horizontal rods 12 are used to efficiently dry the seaweed net 5 with a small force, and are fixed at the lower end of the column 11 toward the direction F in which the seaweed net 5 is stretched. ing. A flanged fixing portion 16 of the drying rope 4 is provided at the tip thereof.

The drying frame 1 is mainly composed of a plastic material having corrosion resistance and rigidity (for example, FRP pipe), and is assembled by appropriately connecting with an elbow joint or the like. Further, in the present embodiment, the horizontal horizontal rod 10 is approximately 4.
7m, pillar 11 is about 1.4m, vertical and horizontal rod 12 is about 0.7
It is formed with a length of m.

The float 2 is for obtaining buoyancy when the seaweed net 5 is dried, and the through hole 20 is formed in the axial center.
And is formed in a substantially columnar shape. This float 2
Is slidably mounted by inserting the through holes 20 into the columns 11 of the drying frame 1, and is fixed at a predetermined position by a stopper 21 which is fixed to the column 11 so that its height can be adjusted. In this embodiment, the substantially middle portion of the float 2 is fixed at a position approximately 0.7 m from the upper end of the column 11. The float position is arbitrarily set according to the wave height.

The fixing ropes 3 are arranged at predetermined intervals so that the drying frame 1 can evenly dry the nori net 5, and the drying frame 1 does not change during the drying operation. As shown in FIG. 1, the abba frame ropes 50a, 50b in the floating culture seaweed net device B are fixed as described above.
Drying frames 1 stretched between each other and arranged at equal intervals.
The rotating rings 13a of the horizontal horizontal rod 10 at (8 places in this embodiment) are connected one after another. The nori net 5 is dried by tensioning the fixing rope 3. Device B in FIG. 1 shows a part of the floating culture seaweed net device, and a large number of the devices in FIG. 1 are installed in series.

When the seaweed net 5 is immersed in the sea, the dehydration rope 4 erects the sideways-sided dry frame 1 so that the whole seaweed net 5 can be simultaneously dried. The end side is fixed to the overhang frame rope 50b, and the start end side is the connecting rod 51b.
And the vertical and horizontal rods 12 in each of the drooping frames 1 are fixed between them.
It is connected to the fixed portion 16 of. And this connecting rod 5
1, a pair of pulleys 52 serving as moving pulleys are provided, and a pair of pulleys 53 serving as constant pulleys are provided on the above-mentioned AB frame rope 50a, and the pulling ropes 4a fixed to the connecting rod 51 are both pulleys. After being stretched around 52, 53, they are integrally connected and fastened to the ABBA rope 50a.

Next, the operation of the embodiment will be described. When the seaweed net 5 is immersed in the sea, the drying rope 4 is loosened, and as shown in FIG. 2 (a), the drying frame 1 is laid sideways and the seaweed net 5 is immersed in seawater. ing. When the seaweed net 5 is to be dried, first, the pulling rope 4a is pulled to move the drying rope 4 to the right in FIG. 2A, and the drying frame 1 is centered on the horizontal shaft portion 13. Rotate. Since this dry-out frame 1 is fixed in place by the fixing rope 3, it does not move to the pulling side of the dry-out rope 4. When the drying frame 1 rotates about the horizontal shaft portion 13, the horizontal horizontal rod 10 is lifted from the sea surface by the buoyancy of the float 2 and the nori net 5 is dried (FIG. 1, FIG.
Figure 2 (b)). In this case, in the initial stage of rotation of the drying frame 1, the tensile force of the drying rope 4 acts on the rotation center of the horizontal shaft portion 13 in the rotation direction at the position separated by the length of the vertical and horizontal rods 12, so that the tensile force Is the rotational force of the drooping frame 1.

When the dried seaweed net 5 is immersed in the sea, the procedure is reversed. in this case,
Since the horizontal horizontal rod 10 rotates so that the horizontal horizontal rod 10 becomes concave downward due to the weight of the seaweed net 5, the dry rod 1 completely immerses the seaweed net 5 in the sea even if the pillar 11 floats on the sea surface. State.

As described above, in the present embodiment, in the initial stage of the rotation for drying the seaweed net 5, as the rotational force for rotating the dry-out frame 1 without reducing the tensile force of the dry-out rope 4. Since the seaweed nets 5 can be efficiently operated, a plurality of seaweed nets 5 can be simultaneously dried out with a small force. The horizontal horizontal rod 10 that supports the seaweed net 5 is the drainage frame 1
Since the seaweed net 5 is always concaved regardless of the rotation, the seaweed net 5 is not completely immersed in the sea to retain floating dust, and the seaweed during seedling raising is not killed. Since it is not necessary to apply an unreasonable force at the time of drying, each part can be formed in a light weight, and since the structure is simple, it can be manufactured at low cost.

The embodiments of the present invention have been described above.
The specific configuration of the present invention is not limited to this embodiment, and any change in design or the like without departing from the gist of the present invention is included in the present invention.

For example, in the embodiment, the fixing rope 3 is
Although it is assumed that the rope is fixed to the rotary ring 13a provided on the horizontal shaft portion 13 of the horizontal horizontal rod 10, the fixing method of the fixing rope is not limited to this, and the arm portion may be separately attached to the column 11 and fixed. May be. Moreover, you may fix by providing an arm part in the center part of a float.

The withdrawal rope 4 is directly fixed to the collared fixing portion 16 provided at the tip of the vertical and horizontal rod 12, but the fixing method of the withdrawal rope 4 is arbitrary, and for example, the vertical and horizontal rod 12 is fixed. An arm portion with a rotating ring may be taken out at the tip portion and fixed to this rotating ring.

The drying frame 1 has a horizontal horizontal rod 10 of approximately 4.7 m,
Although the pillar 11 is formed to have a length of approximately 1.4 m and the vertical and horizontal rods 12 to have a length of approximately 0.7 m, the dimensions of each part can be set arbitrarily. For example, the column 11 has a length of 1.25 m and the vertical and horizontal rod 12 has a length of 0 m. It may be 0.5 m.

The shape of the horizontal horizontal rod 10 is arbitrary, and for example, it can be formed in a linear shape as shown in FIG.

[0026]

As described above, since the floating aquaculture nori net drying apparatus according to claim 1 of the present invention has the above-mentioned structure, it is dried at the initial stage of rotation when the nori net is dried. Since it can be efficiently acted as a rotating force for rotating the drought frame without reducing the pulling force of the rope for use, it is possible to simultaneously withdraw a plurality of seaweed nets with a small force. Further, since it is not necessary to apply an unreasonable force at the time of drying, it is possible to obtain an effect that each part can be formed in a light weight, and that the structure is simple and thus can be manufactured at low cost. Also, since the pulling rope is fixed to the connecting rod via the pulley, the dredging rope can be towed with a small force, and the multiple seaweed nets can be simultaneously dried all over by human power without using power. be able to.

In addition to the above effects, the horizontal horizontal rod supporting the seaweed net is always concave downward regardless of the rotation of the dry frame. As a result, the seaweed net can be completely immersed in seawater, and floating dust is not accumulated, and the seaweed during seedling raising is not killed.
