Description

형망어구 Fishing net
본 발명은 선박에 의해 예인되어 해저토양을 이동하면서, 해저토양에 서식하는 패류를 채취하기 위한 형망어구에 관한 것이다. The present invention relates to a fishing net for collecting shellfish inhabiting the seabed soil while being towed by a ship and moving the seabed soil.
해저토양에 서식하는 패류를 채취하기 위한 어구로써, 갈퀴와 그물망을 구비한 형망어구가 알려져 있다. As a fishing gear for collecting shellfish in seabed soil, a fishing gear with a rake and a net is known.
이러한 형망어구는 로프로 선박과 연결되며, 선박에 의해서 예인되어 해저토양 상을 미끄러져 이동한다. 이때, 형망어구의 갈퀴는 해저토양을 긁으면서, 해저토양에 서식하는 패류를 해저토양과 분리시킨다. 해저토양에서 분리된 패류는 갈퀴의 후방에 설치된 그물망에 유입된다. 그물망에 패류가 수납되면, 형망어구를 선박 위로 끌어올림으로써, 형망어구의 그물망에 수납된 패류를 수거할 수 있다. These fishing nets are connected to the ship by ropes and are towed by the ship and slide on the sea soil. At this time, the rake of the form fishing gear separates the shellfish inhabiting the sea soil while scratching the sea soil. Shellfish separated from the sea soil enter the net installed behind the rake. When the shellfish is stored in the mesh, the shellfish stored in the mesh of the fishing gear can be collected by pulling the fishing gear onto the vessel.
한편, 패류가 서식하는 해저토양은 장소에 따라 그 무르기가 매우 다양한데, 해저토양이 무른 경우에는 형망어구가 해저토양에 빠져 박히는 문제가 흔히 발생하며, 반대로 해저토양이 단단한 경우에는 갈퀴가 해저토양으로부터 받는 저항력 때문에 그 갈퀴를 지지하는 프레임이 휘어지는 문제가 흔히 발생한다. 또한 형망어구를 예인과정에 형망어구가 균형을 잃고 뒤집히는 경우도 흔히 발생한다. On the other hand, the seabed soils inhabited by shellfish vary greatly depending on the place, and when the seabed soil is soft, a problem occurs that the fishing net is drowned in the seabed soil. Due to the resistive resistance, the frame supporting the rake often bends. It is also common for the fishing gear to be unbalanced and overturned during the towing process.
상기의 문제점을 해결하기 위하여 본 발명은, 해저토양 상에서 안정적으로 이동할 수 있는 형망어구를 제공함에 목적이 있다. In order to solve the above problems, an object of the present invention is to provide a fishing net that can stably move on the seabed soil.

In order to achieve the above object, the netting gear according to an embodiment of the present invention, the first slide plate extending in the front and rear direction, and extending in the front and rear direction in a direction crossing the front and rear direction from the first slide plate A plurality of spaced apart second slide plate, one side is coupled to the first slide plate and the other side is coupled to the second slide plate, and arranged on the lower side of the frame, extending to the front lower side of the frame A rake, a mesh disposed at the rear of the frame, a moving member disposed to be able to access and space the frame in a predetermined range from the front of the frame to the front of the frame, and one side is caught by the moving member, The other side has at least one tension member that is caught by at least one of the rake or the frame.
본 발명의 일 실시예에 따른 형망어구에 의하면, 해저토양에 박히거나 균형을 잃고 뒤집히는 것이 효과적으로 억제되므로 안정적으로 해저토양 상을 이동할 수 있다. 또한, 갈퀴가 해저토양으로부터 받는 저항력으로 인해서 그 갈퀴를 지지하는 프레임이 휘어지는 것을 효과적으로 억제할 수 있다.  According to the fishing net according to an embodiment of the present invention, it is effectively suppressed to get stuck in the sea soil or lose balance and upside down can be moved to the seabed soil phase stably. In addition, it is possible to effectively suppress the bending of the frame supporting the rake due to the resistance that the rake receives from the sea soil.

Since the horizontal bar 800 is disposed in a form sandwiched between the rake 400 and the reinforcing table 420, the movement is limited. The horizontal bar 800 may be arranged to be separated from the rake 400, or alternatively, the horizontal bar 800 may be arranged to be fixed to the rake 400 by welding or the like.
인장부재(700)는 복수 개로 마련되며, 각 인장부재(700)는 그 일측이 이동부재(600)에 결합되어 걸리고, 타측이 수평바(800)에 걸리는 형태로 갈퀴(400)에 걸린다. Tensile members 700 are provided in plural, and each tension member 700 is caught by the rake 400 in a form in which one side thereof is coupled to the moving member 600 and the other side is caught by the horizontal bar 800.
인장부재(700)는 로프(710)와 턴 버클(turn buckle-720)을 구비한다. 도 2 및 도 3에 도시된 바와 같이 한 쌍의 로프(710)는 각각 이동부재(600)와 수평바(800)에 결합되고, 한 쌍의 로프(710) 사이에 턴 버클(720)에 배치된다. 따라서 턴 버클(720)을 회전시킴에 따라서 인장부재(700)의 길이는 신축이 가능하다. 인장부재(700)의 길이는 이동부재(600)가 프레임(300)으로부터 멀어질 경우, 팽팽하게 당겨질 수 있을 정도의 길이로 조절된다. The tension member 700 includes a rope 710 and a turn buckle-720. As shown in FIGS. 2 and 3, the pair of ropes 710 are coupled to the movable member 600 and the horizontal bar 800, respectively, and are disposed on the turn buckle 720 between the pair of ropes 710. do. Accordingly, as the turn buckle 720 rotates, the length of the tension member 700 may be extended and contracted. The length of the tension member 700 is adjusted to a length such that when the moving member 600 is far from the frame 300, it can be pulled taut.
제1예인로프(610)는 그 일측이 선박(미도시)에 연결되어 당겨지는 힘을 받는다. The first towing rope 610 is connected to a vessel (not shown), one side receives a force to be pulled.
제2예인로프(620)는 상기 제1예인로프(610)와 이동부재(600)를 연결하며, 복수 개로 이루어진다. 복수의 제2예인로프(620)들은 일측이 상기 제1예인로프(610)의 타측에 결합되고, 타측이 서로 등간격으로 이격되게 이동부재(600)에 결합된다. 즉 제2예인로프(620)는 제1예인로프(610)로부터 복수의 갈래로 갈라지는 형태로 배치되어 이동부재(600)에 결합된다. The second towing rope 620 connects the first towing rope 610 and the moving member 600 and includes a plurality of ropes. The plurality of second towing ropes 620 are coupled to the moving member 600 so that one side thereof is coupled to the other side of the first towing rope 610 and the other side thereof is spaced at equal intervals from each other. That is, the second towing rope 620 is arranged in the form of being divided into a plurality of branches from the first towing rope 610 is coupled to the moving member 600.
다음으로 본 실시예에 따른 형망어구(1)의 작동방법 및 효과에 대해서 설명한다. Next, a description will be given of the operation method and effect of the fishing net (1) according to the present embodiment.
도 4는 도 1의 형망어구(1)의 작동형태를 개략적으로 도시한 측단면도이다. FIG. 4 is a side cross-sectional view schematically showing an operation form of the mesh fishing gear 1 of FIG. 1.
도 4에 도시된 바와 같이, 본 실시예에 따른 형망어구(1)를 침수시켜 해저토양(G) 상에 배치한 후, 형망어구(1)가 전방으로 이동하도록 제1예인로프(610)를 당겨준다. As shown in FIG. 4, the submerged netting gear 1 according to the present embodiment is submerged and disposed on the subsea soil G, and then the first towing rope 610 is moved to move forward. Pull it.
제1예인로프(610)가 당겨지면 형망어구(1)는 전방으로 이동된다. 형망어구(1)가 전방으로 이동하면, 갈퀴(400)에 의해서 해저토양(G)에 서식하는 패류(S)가 들어 올려진다. 해저토양(G)으로부터 들어 올려진 패류(S)는 하판(310)의 상측을 지나 안내부재(900)의 상측을 따라서 그물망(500)의 입구로 들어가게 된다. 안내부재(900)는 소정의 크기의 그물코를 가지므로, 흙 또는 그 그물코보다 작은 크기의 패류(S)가 아래로 빠져 나가도록 한다. 따라서 흙 또는 작은 크기의 패류(S)가 그물로 유입되지 않도록 한다. When the first towing rope 610 is pulled, the mesh fishing gear 1 is moved forward. When the fishing gear 1 moves forward, the shellfish S inhabiting the seabed soil G is lifted by the rake 400. Shellfish (S) lifted from the sea soil (G) passes through the upper side of the lower plate 310 and enters the inlet of the net 500 along the upper side of the guide member 900. Since the guide member 900 has a mesh of a predetermined size, the shell or shellfish S having a smaller size than that of the mesh falls out. Therefore, the soil or shellfish (S) of small size does not flow into the net.
한편, 제1예인로프(610)가 당겨지면 이동부재(600)가 도 4에 가상선으로 도시된 위치에서 실선으로 도시된 위치로 이동되며, 이동부재(600)와 수평바(800)에 연결된 인장부재(700)가 팽팽하게 당겨진다. 즉 인장부재(700)에 의해서 수평바(800)가 당겨지면서 선박의 예인력이 수평바(800)에 작용하게 된다. 한편, 수평바(800)는 갈퀴(400)의 후방에 걸려 있으므로, 인장부재(700)가 수평바(800)를 당기면, 갈퀴(400)도 당겨지게 된다. 결과적으로 선박의 예인력의 적어도 일부는 갈퀴(400)에 직접 작용한다. 예인력의 나머지 일부는 이동부재(600)를 통해서 제1 및 제2수직부재(110,210)에 작용한다. 즉 선박의 예인력이 형망어구(1)의 여러 부분에 분산되어 작용한다고 할 수 있다. Meanwhile, when the first towing rope 610 is pulled, the moving member 600 is moved from the position shown by the virtual line in FIG. 4 to the position shown by the solid line, and connected to the moving member 600 and the horizontal bar 800. The tension member 700 is pulled taut. That is, while the horizontal bar 800 is pulled by the tension member 700, the towing force of the ship acts on the horizontal bar 800. On the other hand, since the horizontal bar 800 is hung on the rear of the rake 400, when the tension member 700 pulls the horizontal bar 800, the rake 400 is also pulled. As a result at least a portion of the towing force of the vessel acts directly on the rake 400. The other part of the towing force acts on the first and second vertical members 110 and 210 through the moving member 600. In other words, it can be said that the towing force of the ship is distributed to various parts of the shape fishing gear (1).
한편, 종래의 형망어구는 예인력이 형망어구의 일측에만 작용하기 때문에, 형망어구가 이동하면서 균형을 잃어 버리기 쉽다. 특히 패류(S)가 서식하는 해저토양(G)이 매우 무른 경우, 형망어구가 해저토양(G)에 빠지면서 균형을 잃어 뒤집히거나 해저토양(G)에 박히는 경우가 많다. 그러나 본 실시예에 따른 형망어구(1)의 경우, 선박의 예인력이 형망어구(1)에 분산되어 작용하여 형망어구(1)를 전체적으로 끌어주므로, 형망어구(1)가 해저토양(G) 상에서 균형을 잃어버리는 것이 효과적으로 억제된다. 따라서 형망어구(1)가 뒤집히거나 해저토양(G)에 박히는 것이 효과적으로 억제된다. On the other hand, in the conventional fishing gear, because the towing force acts only on one side of the fishing gear, the fishing gear tends to lose balance as the fishing gear moves. In particular, when the marine soil (G) inhabited by shellfish (S) is very soft, the fishing nets fall into the ocean soil (G), lose balance, and often overturn or become lodged in the ocean soil (G). However, in the case of the netting gear 1 according to the present embodiment, since the towing force of the ship is distributed to the netting gear 1 and pulls the netting gear 1 as a whole, the netting gear 1 is subsea soil (G). Loss of balance in the phase is effectively suppressed. Therefore, it is effectively suppressed that the shape fishing gear 1 is inverted or stuck to the sea soil G.
또한 본 실시예의 형망어구(1)는 갈퀴(400)에 걸려있는 수평바(800)를 당겨줌으로써 갈퀴(400)에 직접적으로 예인력을 전달하므로, 예인력이 다른 곳으로 분산되지 않고 효율적으로 갈퀴(400)에 전달된다. 따라서 갈퀴(400)가 해저토양(G)으로부터 큰 저항력을 받더라도 효과적으로 이에 대처할 수 있다. In addition, since the netting gear 1 of the present embodiment transfers the towing force directly to the rake 400 by pulling the horizontal bar 800 hanging on the rake 400, the towing force is efficiently distributed without being distributed to other places. Is passed to 400. Therefore, even if the rake 400 receives a large resistance from the sea soil (G) can effectively cope with this.
한편, 종래의 형망어구를 단단한 해저토양(G) 상에서 이동시킬 경우, 갈퀴가 저항력을 많이 받아 그 갈퀴를 지지하는 프레임(300)의 가운데 부분이 후방으로 밀려 휘어지는 경우가 많다. 그러나 본 실시예의 형망어구(1)의 경우, 선박의 예인력이 인장부재(700) 및 갈퀴(400)를 거쳐, 프레임(300)의 가운데 부분을 비롯한 프레임(300) 전체를 전방으로 당겨주므로, 프레임(300)이 그 가운데 부분이 후방으로 밀리는 형태로 휘어지는 것이 효과적으로 억제된다. 따라서 형망어구(1)가 해저토양(G)으로부터 저항력을 크게 받더라도, 프레임(300)이 잘 휘어지지 않게 된다.On the other hand, when the conventional fishing gear is moved on the hard sea soil (G), the rake is subjected to a lot of resistance, the center portion of the frame 300 for supporting the rake is often pushed backward. However, in the case of the fishing net 1 of the present embodiment, the towing force of the ship pulls the entire frame 300, including the center portion of the frame 300 forward through the tension member 700 and the rake 400, It is effectively suppressed that the frame 300 is bent in the form in which the center portion thereof is pushed backward. Therefore, even if the netting gear 1 receives a large resistance from the sea soil G, the frame 300 is hardly bent.
또한 갈퀴(400)는 해저토양(G)의 저항으로 인해서 뒤로 휘어지기 쉬운데, 수평바(800)가 갈퀴(400)의 아래쪽 후방에서 지지하므로 갈퀴(400)가 휘어지는 것을 억제하는 효과가 있다. In addition, the rake 400 is easy to bend back due to the resistance of the sea soil (G), because the horizontal bar 800 is supported from the rear rear of the rake 400 has the effect of suppressing the rake 400 is bent.
도 5는 도 1의 형망어구의 V-V선을 따라 취한 개략적 단면도이며 도 6은 도 5의 VI부분을 개략적으로 확대하여 도시한 도면으로서, 도 5 및 도 6을 참조하면, 형망어구(1)가 해저토양(G)에 놓여질 경우, 제1 및 제2활주판(100,200)의 제1 및 제2돌출부(102,202)는 해저토양(G)에 삽입된다. FIG. 5 is a schematic cross-sectional view taken along line VV of the fishing net of FIG. 1, and FIG. 6 is a schematic enlarged view of a portion VI of FIG. 5. Referring to FIGS. 5 and 6, the fishing net 1 is shown. When placed on the sea soil G, the first and second protrusions 102 and 202 of the first and second slide plates 100 and 200 are inserted into the sea soil G.
도 6에 도시된 바와 같이, 제1활주판(100)이 해저토양(G) 상에 놓여지면 형망어구(1)의 무게로 인하여 제1활주판(100)은 그 하면(104)에 있는 해저토양(G)을 하측으로 누르게 된다. 눌려진 해저토양(G)은 도 6에 화살표로 도시한 바와 같이, 제1활주판(100)의 양측으로 밀려나는 방향으로 힘을 받는다. 그런데 제1활주판(100)의 양측단부에 제1돌출부(102)가 배치되어 있으므로, 해저토양(G)이 더 이상 밀려나지 않게 된다. 만일 제1돌출부(102)가 없다면, 해저토양(G)은 제1활주판(100)이 누르는 힘에 의해서 양측으로 밀려나게 되며, 이로 인해서 제1활주판(100)은 점차적으로 해저토양(G)에 빠지게 된다. 그러나 본 실시예에 따른 형망어구(1)는 제1돌출부(102)를 구비하여, 제1활주판(100)의 하측의 해저토양(G)이 양측으로 빠져나가는 것을 방지해주므로, 제1활주판(100)이 해저토양(G)에 빠지는 것이 효과적으로 억제된다. As shown in FIG. 6, when the first slide plate 100 is placed on the seabed soil G, the first slide plate 100 is located on the bottom surface 104 of the bottom surface 104 due to the weight of the netting gear 1. The soil (G) is pressed downwards. Pressed subsea soil G receives a force in a direction pushed to both sides of the first slide plate 100, as shown by the arrow in FIG. However, since the first protrusions 102 are disposed at both end portions of the first slide plate 100, the subsea soil G is no longer pushed out. If the first protrusion 102 is not present, the sea soil G is pushed to both sides by the pressing force of the first slide plate 100, and thus, the first slide plate 100 gradually moves to the sea soil G. ). However, since the netting gear 1 according to the present embodiment has a first protrusion 102 to prevent the subsea soil G of the lower side of the first slide plate 100 from escaping to both sides, the first slide Falling of the plate 100 into the sea soil G is effectively suppressed.
또한 제1돌출부(102)는 제1활주판(100)의 길이방향으로 연장되게 형성되므로, 제1활주판(100)이 그 길이방향으로만 이동하도록 해준다. 즉 제1돌출부(102)는 제1활주판(100)이 그 길이방향에 교차하는 방향으로 이동하는 것을 억제해주는 효과가 있다. In addition, since the first protrusion 102 is formed to extend in the longitudinal direction of the first slide plate 100, the first slide plate 100 to move only in the longitudinal direction. That is, the first protrusion 102 has an effect of suppressing the movement of the first slide plate 100 in the direction crossing the longitudinal direction.
제2돌출부(202)도 제1돌출부(102)와 동일한 방법으로 제2활주판(200)이 해저토양(G)에 빠지는 것을 억제하며, 제2활주판(200)이 그 길이방향으로만 이동할 수 있도록 해준다. The second protrusion 202 also suppresses the second slide plate 200 from falling into the sea soil G in the same manner as the first protrusion 102, and the second slide plate 200 moves only in the longitudinal direction. To help.
이와 같이 본 실시예에 따른 형망어구(1)는, 해저토양(G)에 빠지는 것이 억제되며 전후방향(±x 방향)에 교차하는 방향의 이동이 억제되므로, 해저토양(G)을 안정적이고 원활하게 이동할 수 있다. As described above, the mesh fishing gear 1 according to the present embodiment is suppressed from falling into the sea soil G and movement of the direction crossing the front and rear direction (± x direction) is suppressed, thereby making the sea soil soil G stable and smooth. Can be moved.
한편, 복수의 제2예인로프(620)는 선박에 연결된 제1예인로프(610)로부터 여러 갈래로 갈라지는 형태로 이동부재(600)에 결합되므로, 선박의 예인력은 이동부재(600) 전체에 골고루 작용한다. 따라서 이동부재(600)의 일부에만 예인력이 집중되지 않으므로 이동부재(600)의 변형 또는 파손이 효과적으로 방지될 수 있다. 또한 예인력이 안정적으로 형망어구(1)에 전달될 수 있다.On the other hand, since the plurality of second towing rope 620 is coupled to the moving member 600 in the form of diverging from the first towing rope 610 connected to the ship, the towing force of the ship is the entire moving member 600 It works evenly. Therefore, since the towing force is not concentrated only on a part of the moving member 600, deformation or breakage of the moving member 600 can be effectively prevented. In addition, the towing force can be stably transmitted to the fishing gear (1).
또한 본 실시예의 형망어구(1)의 인장부재(700)는 턴 버클(720)을 구비하여 길이 조절이 가능하므로, 로프(710)에 작용하는 인장력을 조절할 수 있다. 따라서 해저토양(G)의 상태에 따라, 수평바(800)로 전달되는 예인력의 크기를 적절히 조절할 수 있다. In addition, since the tension member 700 of the form fishing gear 1 of the present embodiment is adjustable in length by having a turn buckle 720, the tension force acting on the rope 710 can be adjusted. Therefore, according to the state of the sea soil (G), it is possible to appropriately adjust the size of the towing force transmitted to the horizontal bar (800).
다음으로 본 발명의 다른 실시예에 따른 형망어구에 대하여 도면을 참조하여 설명한다. Next, a mesh gear phrase according to another embodiment of the present invention will be described with reference to the drawings.
도 7은 본 발명의 다른 실시예에 따른 형망어구의 개략적인 사시도이며, 도 7은 도 7의 VIII-VIII선을 따라 취한 개략적인 단면도이다. 7 is a schematic perspective view of a fishing net according to another embodiment of the present invention, Figure 7 is a schematic cross-sectional view taken along the line VIII-VIII of FIG.
도 7 및 도 8을 참조하면, 본 실시예에 따른 형망어구(2)는 제1 및 제2활주판(100,200), 프레임(300), 갈퀴(400), 그물망(500), 이동부재(650), 인장부재(700), 제1예인로프(610) 및 제2예인로프(620)을 구비한다. 7 and 8, the mesh fishing gear 2 according to the present embodiment includes first and second slide plates 100 and 200, a frame 300, a rake 400, a mesh 500, and a moving member 650. ), A tension member 700, a first towing rope 610 and a second towing rope 620.
제1활주판(100) 및 제2활주판(200)은 전후방향(±x 방향)으로 연장되며 서로 평행하게 배치된다. The first slide plate 100 and the second slide plate 200 extend in the front-rear direction (± x direction) and are disposed in parallel to each other.
프레임(300)은 일측이 제1활주판(100)에 결합되고, 타측이 제2활주판(200)에 결합된다. 프레임(300)이 제1활주판(100) 및 제2활주판(200)에 더욱 견고하게 결합되도록 프레임(300)과 제1활주판(100) 및 제2활주판(200)을 연결하는 보강대(302)가 배치된다. The frame 300 has one side coupled to the first slide plate 100 and the other side coupled to the second slide plate 200. Reinforcing bar connecting the frame 300 and the first slide plate 100 and the second slide plate 200 so that the frame 300 is more firmly coupled to the first slide plate 100 and the second slide plate 200. 302 is disposed.
갈퀴(400)는 프레임(300)의 하측에 고정 결합되며, 전방 및 하측 방향으로 연장되게 형성되다. 갈퀴(400)의 단부는 해저토양(G)에 삽입될 수 있도록, 제1 및 제2활주판(100,200)의 하면보다 더 아래에 위치한다. Rake 400 is fixedly coupled to the lower side of the frame 300, is formed to extend in the forward and downward direction. The end of the rake 400 is located below the lower surface of the first and second slide plates 100 and 200 so that the end of the rake 400 can be inserted into the sea soil G.
그물망(500)은 프레임(300)의 후방측에 배치되며, 도 7에 도시된 바와 같이 그 입구가 프레임(300)에 결합된다. The mesh 500 is disposed at the rear side of the frame 300, and its inlet is coupled to the frame 300 as shown in FIG. 7.
이동부재(650)는 상기 프레임(300)의 전방에 위치하며, 제1활주판(100) 및 제2활주판(200)의 간격방향으로 연장되게 형성된다. 이동부재(650)의 양측에는 이동부재(650)로부터 수직되게 연장되는 지지부재(652)가 결합된다. The moving member 650 is positioned in front of the frame 300 and is formed to extend in the interval direction of the first slide plate 100 and the second slide plate 200. Support members 652 extending vertically from the moving member 650 are coupled to both sides of the moving member 650.
지지부재(652)는 제1활주판(100)에 상면 및 제2활주판(200)의 상면에 형성된 제1 및 제2수직부재(150,250)에 회전가능하게 결합된다. 따라서 지지부재(652)와 결합된 이동부재(650)는 도 8에 도시된 바와 같이, 원호를 그리며 전후방향으로 이동이 가능하다. 즉 이동부재(650)는 프레임(300)에 대해서 접근 및 이격가능하게 배치되는 것이다. The support member 652 is rotatably coupled to the first and second vertical members 150 and 250 formed on the upper surface of the first slide plate 100 and the upper surface of the second slide plate 200. Therefore, as shown in FIG. 8, the movable member 650 coupled with the supporting member 652 may move in the front-rear direction while drawing an arc. That is, the moving member 650 is arranged to be accessible and spaced apart from the frame 300.
인장부재(700)는 이동부재(650)와 프레임(300)의 하측부분을 연결한다. 인장부재(700)의 길이는 이동부재(650)가 프레임(300)으로부터 멀어질 경우, 팽팽하게 당겨질 수 있는 정도의 길이로 이루어진다. 즉 이동부재(650)가 도 8에 실선의 위치에 있을 때 인장부재(700)는 팽팽하게 당겨진다. The tension member 700 connects the lower portion of the movable member 650 and the frame 300. The length of the tension member 700 is made of a length that can be pulled taut when the moving member 650 is moved away from the frame 300. That is, the tension member 700 is pulled taut when the moving member 650 is in the position of the solid line in FIG.
제1예인로프(610)는 그 일측이 선박(미도시)에 연결되어 선박에 의해서 당겨지며, 제2예인로프(620)는 상기 제1예인로프(610)와 이동부재(650)를 연결하며 복수 개로 이루어진다. 복수의 제2예인로프(620)들은 일측이 상기 제1예인로프(610)의 타측에 결합되고, 타측이 서로 등간격으로 이격되게 이동부재(650)에 결합된다. 즉 제2예인로프(620)는 제1예인로프(610)로부터 복수의 갈래로 갈라지는 형태로 배치되어 이동부재(650)에 결합된다. One side of the first towing rope 610 is connected to the vessel (not shown) is pulled by the ship, the second towing rope 620 connects the first towing rope 610 and the moving member 650 It consists of a plurality. A plurality of second towing rope 620 is coupled to the other side of the first towing rope 610, the other side is coupled to the moving member 650 so that the other side is spaced at equal intervals from each other. That is, the second towing rope 620 is arranged in the form of being divided into a plurality of branches from the first towing rope 610 is coupled to the moving member 650.
다음으로 본 실시예에 따른 형망어구(2)의 작동방법 및 효과에 대해서 설명한다. Next, the operation method and effect of the mesh fishing gear 2 according to the present embodiment will be described.
본 실시예에 따른 형망어구(2)를 침수시켜 해저토양 상에 배치한 후, 형망어구(2)가 전방으로 이동되도록 제1예인로프(610)를 당겨주면, 갈퀴(400)에 의해서 해저토양에 서식하는 패류가 들어 올려진다. 들어 올려진 패류는 프레임(300)을 지나 그물망(500)으로 들어가게 된다. After submerging the shape netting gear 2 according to the present embodiment and placing it on the seabed soil, the first towing rope 610 is pulled so that the shape fishing gear 2 is moved forward. Shellfish inhabiting are lifted. The raised shellfish enter the net 500 through the frame 300.
본 실시예에 따른 형망어구(2)도 도 1에 도시된 형망어구(1)와 마찬가지로, 선박의 예인력이 형망어구(2)의 여러 부분에 분산되어 작용한다. 따라서 예인력이 형망어구(2)에 전체적으로 작용하여 형망어구(2)가 균형을 잃어 해저토양(G)에 박히거나 뒤집히는 것이 효과적으로 억제된다. 또한, 프레임(300)이 휘어지는 것도 효과적으로 억제된다. Similar to the fishing net fishing gear 1 shown in FIG. 1, the fishing net fishing gear 2 according to the present embodiment also functions to tow the ship's towing force to various parts of the fishing gear fishing gear 2. Therefore, the towing force acts on the netting gear 2 as a whole, so that the netting gear 2 loses its balance and is effectively suppressed from being lodged or turned over in the sea soil G. In addition, the bending of the frame 300 is also effectively suppressed.
또한 복수의 제2예인로프(620)는 서로 이격되게 이동부재(650)에 연결되어, 이동부재(650)를 전체적으로 당겨주므로, 이동부재(650)의 일부에만 과도한 힘이 작용하는 것을 효과적으로 방지한다.In addition, the plurality of second towing ropes 620 are connected to the moving member 650 to be spaced apart from each other, thereby pulling the moving member 650 as a whole, effectively preventing excessive force acting on only a part of the moving member 650. .
다음으로 본 발명의 또 다른 실시예에 따른 형망어구에 대하여 도면을 참조하여 설명한다. Next, a fishing net according to another embodiment of the present invention will be described with reference to the drawings.

도 9 및 도 10을 참조하면, 본 실시예에 따른 형망어구(3)는 제1활주판(100), 제2활주판(200), 제1수직부재(110), 제2수직부재(210), 프레임(300), 갈퀴(400), 그물망(500), 안내부재(900), 이동부재(600), 수평바(800), 인장부재(700), 제1예인로프(610), 제2예인로프(620) 및 부력체(950)을 구비한다. 9 and 10, the mesh fishing gear 3 according to the present embodiment includes a first slide plate 100, a second slide plate 200, a first vertical member 110, and a second vertical member 210. ), Frame 300, rake 400, mesh 500, guide member 900, moving member 600, horizontal bar 800, tension member 700, first towing rope 610, first A tow rope 620 and a buoyancy body 950.
제1활주판(100), 제2활주판(200), 제1수직부재(110), 제2수직부재(210), 갈퀴(400), 그물망(500), 안내부재(900), 이동부재(600), 수평바(800), 인장부재(700), 제1예인로프(610) 및 제2예인로프(620)은 도 1에 도시된 형망어구(1)의 그것과 실질적으로 동일하므로 이에 대한 구체적인 설명은 생략한다. The first slide plate 100, the second slide plate 200, the first vertical member 110, the second vertical member 210, the rake 400, the mesh 500, the guide member 900, the moving member The 600, the horizontal bar 800, the tension member 700, the first towing rope 610 and the second towing rope 620 are substantially the same as those of the shape fishing gear 1 shown in FIG. 1. Detailed description thereof will be omitted.
프레임(300)은 하판부(310), 상판부(350) 및 세로보강판(360)을 구비한다. The frame 300 includes a lower plate 310, an upper plate 350, and a longitudinal reinforcing plate 360.
하판부(310)는 도 1의 형망어구(1)의 그것과 동일하다. The lower plate part 310 is the same as that of the fishing gear 1 of FIG.
상판부(350)는 하판부(310)의 상측에 배치되며, 판형상으로 형성된다. 상판부(350)의 전방측은 아래방향으로 경사지게 휘어져 있어서 휨에 대하여 더욱 잘 견딜 수 있다. The upper plate 350 is disposed above the lower plate 310 and is formed in a plate shape. The front side of the upper plate 350 is bent inclined downward to better withstand bending.
세로보강판(360)은 상판부(350)와 하판부(310) 사이에 복수 개로 배치되어 상판부(350)와 하판부(310)를 서로 견고하게 고정시켜 준다. 따라서 프레임(300)의 전체의 휨에 대한 저항성이 크게 증가된다. The vertical reinforcing plate 360 is disposed in plurality between the upper plate portion 350 and the lower plate portion 310 to firmly fix the upper plate portion 350 and the lower plate portion 310 to each other. Therefore, the resistance to warpage of the entire frame 300 is greatly increased.
한편, 프레임(300)의 양측에는 각각 결합판이 고정되는데, 각 결합판은 제1수직부재(110) 및 제2수직부재(210)에 볼트로 체결된다. 제1수직부재(110) 및 제2수직부재(210)에는 결합판의 볼트 체결공보다 많은 수의 볼트 체결공이 형성되어 있어서, 결합판의 체결위치를 적절히 조절할 수 있다. 특히 제1수직부재(110) 및 제2수직부재(210)의 볼트 체결공이 상하방향으로 형성된 경우, 프레임(300)의 상하위치를 변경할 수 있으므로 갈퀴(400)가 해저토양(G)에 삽입되는 깊이를 조절할 수 있다. 이처럼 프레임(300)의 상하위치를 조절할 수 있으면 패류(S)의 서식 깊이가 달라지는 경우에도 효과적으로 대처할 수 있다. On the other hand, both sides of the frame 300, respectively, the coupling plate is fixed, each coupling plate is fastened with a bolt to the first vertical member 110 and the second vertical member 210. The first vertical member 110 and the second vertical member 210 has a larger number of bolt fastening holes than the bolt fastening holes of the coupling plate, so that the fastening position of the coupling plate can be properly adjusted. In particular, when the bolt coupling hole of the first vertical member 110 and the second vertical member 210 is formed in the vertical direction, the vertical position of the frame 300 can be changed, so that the rake 400 is inserted into the sea soil G. You can adjust the depth. In this way, if the vertical position of the frame 300 can be adjusted, it is possible to effectively cope with the case where the formatting depth of the shellfish S is changed.
부력체(950)는 물보다 작은 비중을 가져 형망어구(3)에 부력을 제공하는 것으로서, 스티로폼과 같은 발포성 수지 재질로 형성될 수 있다. 부력체(950)는 세로보강판(360) 사이 사이에 배치되며, 형망어구(3)의 전체의 무게중심보다 상측에 위치되도록 상판부(350)의 바로 아래측에 배치된다. 부력체(950)는 부력체(950)는 형망어구(3)에 부력을 제공하므로 형망어구(3)가 해저토양(G)에 빠지는 것을 억제한다. 또한 부력체(950)가 형망어구(3)의 무게중심 보다 상측에 위치되므로 형망어구(3)가 뒤집히는 것을 효과적으로 억제한다. The buoyancy body 950 is to provide a buoyancy to the manggugu 3 having a specific gravity smaller than water, it may be formed of a foaming resin material such as styrofoam. The buoyancy body 950 is disposed between the longitudinal reinforcing plate 360, and is disposed directly below the upper plate portion 350 so as to be located above the center of gravity of the entire shape of the netting gear (3). The buoyancy body 950, the buoyancy body 950 provides the buoyancy force to the net fishing gear (3) suppresses the net fishing gear (3) falling into the sea soil (G). In addition, since the buoyancy body 950 is located above the center of gravity of the shape net gear 3, the shape net gear 3 is effectively suppressed from being reversed.

For example, the first vertical member 110 and the second vertical member 210 of the mesh fishing gear 1 of FIG. 1 may have the same length as that of the first slide plate 100 and the second slide plate 200. Although formed to extend, the first vertical member 110 and the second vertical member 210 may be formed to have a relatively short length so that all of them can be disposed on the front side of the frame 300. In this case, the frame 300 may be directly coupled to the first and second slide plates 100 and 200.
또한 도 1의 형망어구(1)에 있어서, 제1가이드(112) 홈 및 제2가이드 홈(212)은 전후방향(±x 방향)으로 연장되게 형성되는 것으로 설명하였으나, 제1가이드 홈(112) 및 제2가이드 홈(212)은 프레임(300)에 접근 및 이격 가능한 방향이라면 전후방향(±x 방향)에 대하여 경사진 방향으로 형성되어도 무방하다. In addition, although the first guide groove 112 and the second guide groove 212 are formed to extend in the front-rear direction (± x direction) in the mesh fishing gear 1 of FIG. 1, the first guide groove 112 ) And the second guide groove 212 may be formed in a direction inclined with respect to the front-rear direction (± x direction) as long as the frame 300 can be approached and spaced apart.

In addition, the mesh gear (1, 2, 3) according to the embodiment has been described as having a first towing rope 610 and a plurality of second towing rope 620 coupled in the form of branching therefrom, the second It may be coupled to the movable members 600 and 650 directly to the first towing rope 610 without the towing rope 620.
또한 상기 실시예에서 부력체(950)는 상판부(350)의 하측에 배치되는 것으로 설명하였으나, 형망어구(3)의 무게중심보다 위쪽에 위치되면 되므로 상판부(350)의 상측에 배치될 수도 있다. In addition, in the above embodiment, the buoyancy body 950 has been described as being disposed below the upper plate portion 350, but may be disposed above the upper plate portion 350 because the buoyancy body 950 should be located above the center of gravity of the shaped fishing gear 3.
또한 상기 실시예에 따른 형망어구(1,2,3)는 본 출원인에 의한 대한민국 공개특허 제2009-0127105호에 기재된 구성요소 들을 더 포함하는 형태로 구체화될 수도 있다.
