摘要:
The present invention relates to a power-saving type seine net capable of unfolding left and right wing nets including a large net and a small net through a net boat and catching a group of fish stuck between the wing nets through a bag net in the rear side. A net knot of a bugle net, connecting the tips of the small left and right nets with a bag net, is rotated at an angle of 90 to an existing shape or formed into a rectangular shape instead of a diamond shape, and each net knot is thermally treated for reinforcement, while a connection method for the bugle net is improved for making a curved connection between the small nets and the bag net, and thus, a pocket phenomenon of the small nets is minimized to significantly reduce tow rope resistance. Since a large buoyant part is hung on the rear end part of the small nets to float the nets, even without the operation of a fish detecting boat, the mouth of the bag net is opened sufficiently to check a corresponding position for fishing, and the front end of a large net and a trawl warp are connected through a net Snell method, and thus, the large net is stably unfolded and the size of the net is able to be reduced. Since the diameter of the bag net is tapered backwards, the tow rope resistance is reduced, and the left and right sides of end nets are made longer than the left and right side nets and connected through a wrinkle combination method, and thus, the rear end of the bag net is able to be unfolded into a spherical shape which is proper for fish to swim in.본 발명은 오비기그물과 수비그물이 포함된 좌,우측 날개그물을 망선을 이용하여 전개시키고, 각각의 날개그물 사이에 가두어진 어군을 후방측의 자루그물로 포획토록 한 권현망어구에 관한 것으로서, 좌,우측 수비그물의 끝단을 자루그물과 연결하는 나발그물의 그물코가 기존 방식에서 90도 각도로 회전된 형태 또는 마름모가 아닌 사각 형태를 이루도록 하고, 각 그물코의 매듭부위마다 보강열처리를 행하는 한편, 수비그물과 자루그물의 연결부위가 완만한 곡선을 이루도록 나발그물의 연결방식을 개선시킴으로서, 수비그물의 포켓현상을 최소화시켜 어군회피와 예인저항을 크게 줄이도록 하며, 수비그물의 후단부 상측에 대형부자를 매달아 이를 수면으로 부상시킴으로서, 어탐선을 운용하지 않더라도 자루그물의 입구를 충분히 벌려 그 위치까지 확인하면서 조업이 가능토록 하고, 오비기그물의 선단측과 망선용 끌줄과의 연결방식을 그물목줄 방식으로 개선시킴으로서, 오비
