Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings, but the drawings are merely for illustration purposes and are not intended to limit the present invention.

As shown in FIGS. 1 to 3, the present invention is a fishing net, which is applied to purse seine, tow net, etc., and mainly pulls a fishing net 10 with a fishing boat 100 to capture a school of fish 200. The fishing net (purse seine, tow net, etc.) 10 mainly includes a fishing net main body 1.

As shown in FIGS. 1 to 3, the fishing net main body 1 is made by weaving a plurality of net ropes (reference numerals omitted), and the fishing net main body 1 includes the braided net 2 and the upper, lower, and left of the braided net 2. The upper fence rope 3 provided so as to surround in the order on the right side, the lower fence rope 4, the left mating net 5, and the right mating net 6 are included, and an intermediate net portion 7 is provided in the middle of the braided net 2. Have. The braided net 2 is further woven between the partition rope 21 provided between the upper enclosure rope 3 and the lower enclosure rope 4 and the upper enclosure rope 3 and the partition rope 21 and arranged side by side with each other. It has a plurality of upper mesh regions 22 and a plurality of lower mesh regions 23 woven between the lower fence rope 4 and the partition rope 21 and arranged side by side with each other.

Of these, each upper mesh region 22 has a plurality of first rhombic meshes 221 and each lower mesh region 23 has a plurality of second rhombic meshes 231. The plurality of first diamond meshes 221 and the plurality of second diamond meshes 231 are arranged in opposite directions with respect to the partition rope 21, and the dimensions of the first diamond mesh 221 of the plurality of upper mesh regions 22 are on the left. The dimensions of the second rhombic mesh 231 of the plurality of lower mesh regions 23 gradually decrease from the mating net 5 and the right mating net 6 toward the intermediate net portion 7, and the dimensions of the left mating net 5 and the right mating net 6 to the intermediate net It gradually decreases toward the 7th part.

Details will be described below. As shown in FIG. 3, the weaving direction of the plurality of first rhombic meshes 221 and the weaving direction of the plurality of second rhombic meshes 231 are opposite to each other, and the plurality of upper mesh regions 22 and the plurality of lower mesh regions are opposite to each other. Since the quantity and position of the 23 are the same, the plurality of first rhombic meshes 221 and the plurality of second rhombic meshes 231 are arranged in opposite directions and symmetrically with respect to the partition rope 21.

Further, in the present embodiment, the dimensions of the first rhombic mesh 221 of the two adjacent upper mesh regions 22 and the second rhombic mesh 231 of the two adjacent lower mesh regions 23 are changed as follows. To do. A first partition rope 24 is provided between two adjacent upper mesh regions 22, and the edge of the first diamond mesh 221 located on one side of the first partition rope 24 is the other. It is composed of the edges of two adjacent first rhombic meshes 221 of. A second partition rope 25 is provided between two adjacent lower mesh regions 23, and the edge of the second diamond mesh 231 located on one side of the second partition rope 25 is the other. It is composed of the edges of two adjacent second rhombic meshes 231 on the side.

Further, each first partition rope 24 is one inclined line gradually approaching the intermediate net portion 7 from the partition rope 21 to the upper enclosure rope 3, and each second partition rope 25 is from the partition rope 21 to the lower mesh. It is an inclined line that gradually approaches the intermediate net portion 7 up to the region 23.

The size of each first rhombic mesh 221 and the size of each second rhombic mesh 231 are between 0.9 m and 30 m. The mesh size of the intermediate net portion 7 is less than the dimension of each first rhombic mesh 221 and the dimension of each second rhombic mesh 231 and is mainly concentrated in the intermediate net portion 7 when catching the school of fish 200. The mesh size of the intermediate net portion 7 is small so that the school of fish 200 does not escape from the mesh.

As shown in FIG. 1, as the upper enclosure rope 3, a rope body floating on the sea surface can be adopted, and in the present embodiment, a plastic rope will be described as an example, but the present invention is not limited to this. Of these, the upper fence 3 is connected to the upper edge of the fishing net body 1 in order to make the upper rope 3 easier to float on the sea surface.

As shown in FIG. 1, as the lower enclosure rope 4, a rope body that sinks in the sea can be adopted, and in the present embodiment, a nylon rope will be described as an example, but the present invention is not limited thereto. Of these, the lower fence 4 is connected to the lower edge of the fishing net body 1 in order to make it easier for the lower fence 4 to be submerged in the sea, and the upper rope 3 is made easier to catch the school of fish 200. The fishing net main body 1 can be relatively opened with respect to the above. Of these, a rope body having low extensibility is adopted for the upper fence rope 3 and the lower fence rope 4, so that the fishing net main body 1 can be regulated so as not to be deformed.

As shown in FIGS. 1 to 3, the fishing net 10 of the present embodiment has its own rhombic shape because it uses a plurality of first rhombic nets 221 and a plurality of second rhombic nets 231. When the fishing net body 1 is collected, the plurality of first rhombic nets 221 and the plurality of second rhombic nets 231 are automatically folded and superposed. By doing so, the effect of reducing the bulk of the fishing net tatami mat and improving the smoothness of net recovery can be achieved.

Further, a plurality of first rhombic nets 221 and a plurality of second rhombic nets 231 are arranged in opposite directions with respect to the partition rope 21, and the partition ropes 21 are formed by the upper rope 3 and the lower rope 4. Since it is located in the middle, when collecting the fishing net body 1, the plurality of first rhombic nets 221 and the plurality of second rhombic nets 231 are close to the middle (partition rope 21) of the braided net 2. Therefore, it is possible to avoid the occurrence of a problem that the force action becomes non-uniform and shift to one side, and the smoothness of net recovery of the fishing net 10 can be further improved.

Further, each first partition rope 24 is one inclined line gradually approaching the intermediate net portion 7 from the partition rope 21 to the upper fence rope 3, and each second partition rope 25 is a lower fence from the partition rope 21. The direction of collecting the plurality of upper mesh regions 22 and the plurality of lower mesh regions 23 by the inclined line gradually approaching the intermediate net portion 7 up to the rope 4 (from the left mating net 5 and the right mating net 6 to the intermediate net portion). (Recovering up to 7) will guide you to fold and collect toward the position of the intermediate net portion 7, so that the net collection of the fishing net 10 can be made smoother.

Further, when collecting the fishing net main body 1, the school of fish 200 first gathers at the intermediate position of the braided net 2 and escapes from the net when the space in the middle of the braided net 2 becomes insufficient. The dimensions of the first rhombus mesh 221 of 22 gradually decrease in the direction from the left mating net 5 and the right mating net 6 toward the intermediate net portion 7, and the dimensions of the second rhombus mesh 231 of the plurality of lower mesh regions 23. Is gradually smaller from the left mating net 5 and the right mating net 6 toward the intermediate net portion 7, so that the mesh of the braided net 2 is large on both sides and small in the middle, and all the meshes are small. In comparison, the fishing net 10 of the present embodiment has the advantages of low cost, light weight, and compactness.

FIG. 4 shows another embodiment of the fishing net 10 of the present invention, and the fishing net 10 shown in FIG. 4 has substantially the same configuration as the fishing net 10 shown in FIGS. 1 to 3. The difference between the fishing net 10 of FIG. 4 and the fishing net 10 of FIGS. 1 to 3 is the structure of the intermediate net portion 7.

In the fishing net 10 of FIGS. 1 to 3, the intermediate net portion 7 is a flat net, but the intermediate net portion 7 is not limited to this, and may be a bag net as in the fishing net 10 of FIG.
