Description

[Detailed Description of the Invention] The present invention relates to a large group float used mainly for a large float commonly called a Sarco used for fixed nets.

As shown in FIG. 1, the fixed net is stretched out in a long spindle shape when viewed from above. A large number of floats 3 are attached to the upper edge of the net, and both ends of the stretched net are strongly fixed by huge platform floats 7. As the name suggests, the fixed net must be fixed, so the bottom of the net under each float 3 is fixed to the seabed, although the explanation of the means will be omitted. On the other hand, fixed nets are usually spread out in a direction perpendicular to the shore, ie, perpendicular to the tidal current, due to the migratory nature of fish. Therefore, if there is a fast current during the ebb and flow of the tide, the float will be swept to the side, and since the bottom is fixed, there will not be enough float and it will be submerged below the sea surface, and the top surface of the net will become a free passage for fish, losing its function as a fixed net. It turns out.
To prevent this from happening, floats with a high buoyancy, commonly called Sarco 8, are fixed to the net outside of the position between several floats, and the net is pulled.
The buoyancy of float 3 is maintained.

The present invention is intended to provide a large float that can replace this Sarco. Sarco 8 is the second
As shown in the figure, an oblong float is used by being tied to a rope 9, but because of its large size and the need to increase its buoyancy, blow-molded products are often made of polyethylene. Due to the manufacturing method, it is difficult to make blow-molded products thick, and the wall thickness tends to be uneven, so they are often damaged due to collisions with floating objects. However, replacing this at sea is quite troublesome.

The present invention aims to use a large number of hollow floats 3 as a replacement float for a single Sarco 8, with ring-shaped retaining rings 1 and 1' made of pipes or plates arranged at both ends, and rod-shaped floats. A large number of float members 4 having a plurality of hollow floats 3 inserted therein are arranged and fixed in a ring shape between retaining rings on the object 2, and a retaining ring or a reinforcing member 5 of the ring is attached.
The main feature is a large gathering float for the fish industry, which is equipped with a hook 6 for fixing the float.

3 and 4 illustrate one example of the present invention, in which FIG. 3 is a front sectional explanatory view, and FIG. 4 is a side view from the retaining ring 1' side of FIG. 3. In the figure, 1 and 1' are retaining rings made of pipes, and 4 is a float member with a hollow float 3.
Eight float members 4, each of which is inserted through a tubular rod 2, are welded and fixed to one retaining ring 1. Further, in the figure, reference numeral 5 denotes a reinforcing material for the retaining ring, which is welded to both retaining rings at the diameter portion of the retaining ring, and a float member is attached to the retaining ring 1 side at the center portion thereof as well. Further, in the figure, 6 is a hook for fixing the float, which is attached to the retaining ring 1', but its attachment position and shape are not particularly limited as long as it is welded to ensure sufficient fixation. In addition, 1 in the figure
0 is the tightening and fixing part of the float. At this part, the flange 11 at the tip of the rod to which the float is fixed and the flange 12 at the tip of the short tube protruding inward of the other retaining ring facing this are butted, The retaining rings on both sides are integrated with bolts, forming one float as a whole.

In the above example, the retaining ring and the rod or reinforcing material of the float member are all made of pipes, but the retaining ring and the reinforcing material may be made of sheet material, including angle materials, and rods are not required. There is no need for a thigh tube. In short, it is desirable to use a material that is strong, lightweight, and easy to work with. Further, the number of floats 3 in the float member 4 may be freely changed, such as 5 or 8, depending on the size of the floats 3, the place of use, etc. Further, in order to obtain a large sarco, it is optional to make the retaining ring double concentrically or to make the reinforcing material cross-shaped, although not shown in the drawings.

In FIGS. 3 and 4, the float member 4 is the retaining ring 1'.
Although the float member 4 is fixed on the inside of the retaining rings 1 and 1' as shown in FIG.
As shown in FIG. 5, the retaining rings 1, 1' may be screwed from the outside.

As described above, this invention uses a strong hollow float 3 made of sponge, so there is almost no risk of damage, and it can be disassembled and assembled freely, so it is extremely suitable as a float to replace Sarco for fixed nets. It is.
