Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

≪ Example 1 >

Figure 2 is a perspective view of the jellyfish shredding net according to an embodiment of the present invention.

As shown in Figure 2 jellyfish shredding net according to the present invention is the upper and lower support (100,110), left and right support (120,130), the front buoyancy member 140, fishing net 150, jellyfish removal net ( 160, the rear buoyancy member 170 and the rear needle 180.

First, the upper and lower supporters 100 and 110 and the left and right supporters 120 and 130 are made of steel pipes so that the inlet of the net has a rectangular shape, and the traction rope 10 is connected to the upper and lower supporters 100 and 110.

In addition, the upper support member 100 is fixed to the front buoyancy member 140, the front buoyancy member 130 is continuously coupled to the EVA (Ethylene-Vinyl Acetate) material of the upper support 100 is horizontal To be located on the sea surface.

Here, the left and right supporters 120 and 130 are hinged to one ends of the upper and lower supporters 100 and 110, respectively, (H1, H3), the hinge portion (H2) is formed in the center.

Looking at the left and right supporters 120 and 130 in detail, FIG. 3 is a diagram of FIG. 2, and FIG. 4 is a cross-sectional view of part A of FIG. 2.

As shown in FIG. 4, the lower supporter 110 and the left supporter 130 are coupled through the hinge portion H1, and specifically, the connection member 132 is installed at the lower end of the left supporter 130, and the bolt Combination with the lower support 110 through (B) is configured so that the left support 130 can be rotated around the hinge point.

Therefore, as shown in FIG. 3, the left and right supports 120 and 130 may be folded around the hinge portion H2 when stored, and the jellyfish may be unfolded in a square shape when the jellyfish is removed. By maintaining the horizontal in the lower side of the support 100 to maintain the inlet of the net in a rectangular shape.

In addition, since the upper and lower support members 100 and 110 and the left and right supporters 120 and 130 are made of a steel pipe, the lower support 110 may sink to the bottom of the water due to its own weight, thereby eliminating the need for a separate needle.

Next, the fishing net 150 has an inlet in a rectangular shape through the upper and lower supporters 100 and 110 and the left and right supporters 120 and 130, and is gradually narrowed to the rear, and the jellyfish flowing through the inlet is a jellyfish removal net 160. To be moved to the side.

The grid size of the fishing net 150 is to be made somewhat smaller than the size of the general jellyfish, the jellyfish removal net 160 is made in the form of a square wire mesh formed on the back of the fishing net 150, cut the jellyfish directly It will play a role.
