Description

중층 조업용 로프 트롤망{Rope trawlnet for operation in the middle layer}Rope trawlnet for operation in the middle layer}

본 고안은 명태나 대구와 같은 중층 수역에서 주로 서식하는 어종을 대상으로 하는 로프 트롤망의 원통그물을 개량한 중층 조업용 로프 트롤망에 관한 것이다.The present invention relates to a middle-tier fishing rope trawl network that improves a cylindrical net of rope trawl nets targeting fish species inhabiting middle-tier waters such as pollock and cod.

일반적으로 중층에서 조업하는 트롤 어구는 작업선에서 대상 수심에 어구를 적용하기 위한 끝줄, 어구를 전개시키기 위한 전개판, 후릿줄, 그물 목줄과 원통그물 및 어획물이 최종적으로 모이는 끝자루로 구성되어 있다.In general, trawling fishing in the middle layer consists of an end line for applying the fishing gear to a target depth, a development board for developing the fishing gear, a fishing line, a net collar and a cylindrical net, and an end where the catch is finally collected. .

이중에서 원통그물은 발을 연결한 망목구조의 로프파트로 된 입구부분과 망지로 된 네트파트로 형성된 끝부분을 서로 연결한 구조로 되어 있는 데 종래의 원통그물은 로프파트와 네트파트가 망 둘레 폭이 급격하게 감소하는 구조로 되어 있으므로 잦은 파단사고가 일어나고 유속이 일정하게 유지되지 않으므로 인해 어획성능의 저하는 물론 예망효율의 저하를 가져오게 되며 뜸줄 및 발줄의 망지 연결부위가 자주 밀리거나 파단되어 그물 전체가 말리는 사고가 발생하고 또 4가닥의 힘줄이 와이어 로프로 되어 그물 자체가 무거워져 예망하는 데 더 큰 힘이 소요되는 등 여러가지의 폐단이 있었다.Among them, the cylindrical net has a structure in which the entrance part of the rope part of the net structure connecting the feet and the end part formed of the net part of the net are connected to each other. In the conventional cylindrical net, the rope part and the net part have a circumference of the net. As the width is reduced rapidly, frequent breakage accidents occur and the flow rate is not kept constant, resulting in a decrease in catching performance and a decrease in net efficiency. There were various closures, such as an accident that the whole net was dried up and the four tendons were made of wire ropes, which made the net itself heavy and took more power to anticipate.

본 고안은 이와같은 점을 감안하여 안출한 것으로 로프파트에 네트파트를 연결할 때 아이 스플라이스를 하여 그물이 밀리는 문제점을 해소하고 힘줄을 무거운 와이어 로우프로 형성하지 않고 망지 자체를 여러겹으로 합쳐 동일한 강도를 가진 힘줄로 구성하므로서 종래의 많은 폐단을 해소한 것 인데 이를 첨부도면에 의거 상술하면 다음과 같다.The present invention has been devised in view of the above, and it solves the problem of pushing the net by splicing the net part when connecting the net part to the rope part, and combines the netting itself in multiple layers without forming the tendon as a heavy wire rope. By eliminating a lot of the conventional lung by configuring a tendon with a detailed description based on the accompanying drawings as follows.

로프파트(1)와 망지(2)로 된 네트파트(3)가 연결되고 수개의 힘줄(4)이 설치된 트롤어구(가)의 원통그물(5)을 구성함에 있어서, 망지(2)의 연결단에 ㅅ자 형상의 연결발(6)과 두개의 분리된 결속발(7)을 각각 교호로 형성하여 연결발(6)은 로프파트(1)의 매듭(8)에 묶고, 결속발(7)은 양측에 위치한 발(9)에 뚫은 구멍(10)에 관통시켜 상하로 아이 스플라이스 하여 결속하며, 힘줄(4)의 설치부분에 망지(2)를 여러겹으로 합쳐 결속로프(11)로서 일정간격으로 결속하므로서 힘줄(4)을 구성함을 특징으로 한 것이다.Rope part 1 and net part 3 of the netting 2 are connected, and when constructing the cylindrical net 5 of the trawl gear (A) in which several tendons 4 were installed, the connection of the netting 2 is carried out. At the end, the zigzag-shaped connecting foot 6 and two separate binding feet 7 are formed alternately, so that the connecting foot 6 is tied to the knot 8 of the rope part 1, and the binding foot 7 is formed. Is pierced through the holes 10 in the feet 9 located on both sides and spliced up and down to bind. The joints 2 are combined in multiple layers in the installation portion of the tendon 4 as a binding rope 11. It is characterized by configuring the tendon 4 by binding at intervals.

이와같이 된 본 고안은 원통그물(5)의 로프파트(1)와 네트파트(3)를 연결함에 있어 네트파트(3)를 구성하고 있는 망지(2)의 연결단에 ㅅ자 형상의 연결발(6)과 두개의 분리된 결속발(7)을 각각 교호로 형성하여 연결발(6)은 로프파트(1)의 매듭(8)에 묶고, 결속발(7)은 발(9)의 구멍(10)에 관통시켜 상하로 아이 스플라이스 하여 결속한 것이므로 로프파트(1)와 네트파트(3)는 매우 튼튼하게 결속되는 데 여기서 결속발(7)은 로프파트(1)의 발(9)에 뚫은 구멍(10)에 관통되어 상하로 스플라이스 한 것이므로 결속발(7)은 발(9)로 부터 밀리지 아니하고 결속된 그 위치에 고정됨에 따라 파망사고가 발생하지 않게 된다.In this way, the present invention is connected to the rope part 1 of the cylindrical net 5 and the net part 3 at the connecting end of the netting 2 constituting the net part 3 in the s-shaped connecting foot 6 ) And two separate tie (7) are formed alternately, so that the connecting foot (6) is tied to the knot (8) of the rope part (1), and the tie (7) is the hole (10) of the foot (9). Rope part (1) and net part (3) are very tightly bound, so that the binding foot (7) is drilled on the foot (9) of the rope part (1). Since the piercing foot 7 is not pushed from the foot 9 but fixed at the position where the binding foot 7 is spliced up and down through the hole 10, the breaking accident does not occur.

특히 본 고안의 연결구조는 로프파트(1)와 네트파트(3)의 연결부위가 큰 매듭없이 연결되므로 망폭이 균일하게 줄어들게 되므로 예망시 예망방향에 대해 전체적으로 일정한 각도를 유지하게 되어 유속이 균일하게 흐르게 됨에 따라 입망된 고기가 로프파트와 망지 연결부에서 발생하는 와류에 의해 이탈되지 않게 되고 선속을 증가시켜 주며 또한 소해면적이 기존망에 비해 크므로 탁월한 군집효과가 있다.In particular, the connection structure of the present invention is connected to the rope part (1) and the net part (3) is connected without a large knot, so that the net width is reduced uniformly, so that the flow rate is uniformly maintained at an overall angle with respect to the direction of the forecast when As it flows, the wondrous meat is not dislodged by the vortices generated from the rope part and the net joint and increases the ship speed, and also has an excellent clustering effect because the seabed area is larger than that of the existing net.

그리고 힘줄(4)을 구성함에 있어 종래와 같이 와이어 로프를 사용하지 않고 힘줄의 설치부위에 있는 망지(2)를 여러겹으로 합쳐 결속로프(11)로서 결속하여 와이어 로프을 대신하는 힘줄(4)을 형성한 것이므로 수중중량이 줄어들어 예망효율이 증가하고 자재비가 절감됨은 물론 전개판의 전개 성능 및 끌줄의 길이에 따라 변화하는 전개판의 전개 간격에 별도의 인위적인 조작없이 그물 자체가 유동적으로 대처하는 특성을 가지게 되는 것이다.In forming the tendon 4, the tendon 4 that replaces the wire rope by binding the net 2 on the installation portion of the tendon in multiple layers and binding it as a binding rope 11 without using a wire rope as in the prior art. As it is formed, the weight in the water is reduced, the net efficiency is increased, the material cost is reduced, and the net itself responds flexibly to the development gap of the deployment plate and the development interval of the deployment plate that changes according to the length of the cord. To have.

이와같이 본 고안은 로프파트(1)와 네트파트(3)의 연결을 아이 스플라이스방식으로 연결하였으므로 매듭에 의한 와류현상이 줄어들어 저항을 감소시켜 예망효율을 증가시키고 그물이 밀리는 현상과 파단을 해소하였으며 수중중량을 줄여 자재비를 절감하고 이로인해 어로 작업의 효율과 어획증대를 가져다 주는 등 그 효과가 매우 크다.Thus, the present invention connected the rope part (1) and the net part (3) by the eye splice method, so the vortex caused by the knot is reduced, the resistance is reduced, the net efficiency is increased, and the net is pushed and the breakage is eliminated. Reducing the weight in the water saves material costs, which is very effective in bringing the efficiency of fishing and the increase of fishing.
