Description
본 고안은 연안해역의 양식 어민들이 미역, 김, 굴 등의 양식어망을 바다 위에 띄우거나 가두리 양식장 등에서 어망을 일정한 위치에서 부상(浮上)시키기 위해서 사용하는 부구(이하 어망용 부구이라 통칭함)의 구성에 관한 것으로, 본 고안의 특징은 종래 발포스티로폼이나 발포우레탄 등 단일재질의 부상체(浮上體)로 된 어망용 부구의 구성과 달리 환경공해를 유발하지 않는 재질인 EVA스펀지 등 저밀도, 고강도 발포수지체를 이용하여 부력도가 좋은 중공체의 형태로 구성한 것이다.This design is used for fishing fishermen in coastal waters to float seaweed, seaweed, oysters, etc. on the sea, or to float them in a fixed position in cages, etc. (hereinafter referred to as fishing nets). The present invention relates to a low density, high strength foam, such as EVA sponge, which is a material that does not cause environmental pollution, unlike the configuration of a fishing net for a single floating material such as foamed styrofoam or foam urethane. The resin is used to form a hollow body having good buoyancy.
종래 연안해역의 각종 양식망이나 양식어류의 양식망을 해수에 띄워올리기 위하여 사용되고 있는 어망용 부구의 일반적 구성은 대부분 그 재질이 발포스티로폼 단일재질의 통체형으로 구성되고, 이 스티로폼 통체의 외면을 보호하기 위하여 경질합성수지 통체나 두꺼운 비닐포지를 덧씌워서 내후성(耐候性) 유지나 파손방지 효과를 부여하고 있는 실정이다.The general structure of fishing nets used to float various kinds of fish farming nets and fish farming nets in coastal waters in the seawater is mostly composed of a single body of foamed styrofoam and protects the outer surface of the styrofoam body. In order to achieve this, a hard synthetic resin body or a thick plastic bag is covered to provide weather resistance or damage prevention effect.
그러나 이러한 종래의 구성은 외통체의 케이싱이 어선과의 충돌 등 외부와의 충격에 의해 파손되거나 외포지가 찢어지기 쉬우므로 내부의 스티로폼 발포체가 쉽게 부서져서 수명이 비교적 단기적이고, 특히 부서진 스티로폼 입자가 연안해역을 오염시키는 주원인이되고 있음에도 불구하고 지금까지 마땅한 대체 재료가 개발되지 않아 이의 합리적인 개선이 이루어지지 못하였다.However, such a conventional configuration is that the casing of the outer cylinder is easily damaged by an impact from the outside such as a collision with a fishing boat, or the outer bag is easily torn, so that the inner styrofoam foam is easily broken, so that the broken styrofoam particles are particularly in coastal areas. In spite of being the main cause of pollutants, no reasonable alternatives have been developed until now.
본 고안은 이러한 문제점에 착안하여 장기간 실험연구를 한 결과 스티로폼 재료가 아닌 저밀도 EVA스펀지 발포체를 어망용 부구의 구성재료로 선택함으로써 어망용 부구의 본래 기능 유지와 함께 환경 보존에도 크게 일조할 수 있도록 한 것이다.In view of these problems, the present inventors have conducted long-term experimental studies, and selected low-density EVA sponge foam as a constituent material for fishing nets, rather than styrofoam material, so as to contribute to preserving the original function of fishing nets and conserving the environment. will be.
어망용 부구는 항상 해수면에 부상되어 있으므로 장기적으로 양호한 부력도를 유지하면서 어선 등 외부 충격에 의해 파손되지 않아야 하고, 기온 또는 태양광선에 의한 내후성이 양호하여야 함은 물론 재료 자체가 2차환경 공해를 유발하지 않아야 한다.Since fishing nets are always floated on the sea surface, they should not be damaged by external impacts such as fishing boats while maintaining good buoyancy in the long term, and the weather resistance due to temperature or sunlight should be good. Should not be triggered.
본 고안은 이러한 어망용 부구의 물성요건에 적합한 재료와 구성형태를 충족할 수 있는 보다 개선된 어망용 부구를 제공하려는데 기술적 과제를 둔 것이다.The present invention aims to provide a more improved fishing gear that can meet the material and configuration suitable for the properties of the fishing nets.

도 1은 본 고안의 구성사시도이고, 도 2는 본 고안의 단면도이다.1 is a perspective view of the present invention, Figure 2 is a cross-sectional view of the present invention.
부구 통체(1)의 내부 공간부(2)는 중공체로 된 원통형으로 구성하며 좌우 양측에는 캡(4)이 씌워진다.The inner space part 2 of the float cylinder 1 is comprised of a cylindrical body made of a hollow body, and caps 4 are covered on both left and right sides.
구성재질은 합성수지 재질 중에서 내후성, 내충격성, 내구성면에서 안정감이 높은 EVA발포수지체로 구성한다.The material is composed of EVA foamed resin with high stability in weather resistance, impact resistance and durability among synthetic resin materials.
EVA발포수지는 저밀도 고강도 수지체로서 양호한 내구성과 함께 환경공해를 일으키지 않는 재질이므로, 본 고안의 실시예에서는 EVA발포수지체를 주 구성재질로 선택하였다.Since the EVA foamed resin is a low-density, high-strength resin body with good durability and does not cause environmental pollution, in the embodiment of the present invention, the EVA foamed resin body was selected as the main constituent material.
통체(1)는 양측에 어망로프를 행거할 수 있도록 통상의 행거고리(7)가 일체적으로 형성되며, 중간에는 묶음줄이 결속되기 용이하도록 1~2개의 요입홈(8)을 형성한다.The cylinder 1 is formed with a single hanger ring 7 integrally formed to hang a fishing rope on both sides, and forms one or two concave grooves 8 in the middle so as to easily bind a bundle line.
통체(1)의 양측에 결합되는 캡(4)은 내측에 보강돌조(6)가 형성되어서 일정한 내구성, 견고성을 유지할 수 있도록 하고 외주면에 단입(段入) 돌윤부(5)를 환설하여 이 돌윤부(5)가 통체(1) 양단 내측의 대향부에 요설한 결합홈(3)에 상호 결합될 수 있도록 한다.The cap 4 coupled to both sides of the cylinder 1 has a reinforcement protrusion 6 formed therein so as to maintain a constant durability and rigidity, and turn the indentation bulge 5 on the outer circumferential surface of the cap 4 to form this stone. The lubrication part 5 is mutually couple | bonded with the engaging groove 3 concave in the opposing part inside the both ends of the cylinder 1.
통체(1)의 내부는 좌우 캡(4)의 결합에 의해 내부 공간부(2)가 형성되며, 외부로부터 해수가 유입되지 않도록 좌우 캡(4)의 결합부위, 즉 돌윤부(5)와 결합홈(3) 부위에는 방수 접착제를 충분히 도포하여 양호한 밀폐상태를 유지시키므로써 내부 공간부(2)가 충분한 부력기능을 가지도록 한다.The inside of the cylinder 1 has an inner space portion 2 formed by the coupling of the left and right caps 4, and is coupled to the engaging portion of the left and right caps 4, that is, the bulging portion 5, so that seawater does not flow from the outside. The groove 3 is sufficiently coated with a waterproof adhesive to maintain a good sealing state so that the inner space 2 has a sufficient buoyancy function.
한편, 별도의 실시예로서 내부 공간부(2)에 비닐지로 된 에어팩시트(9)를 두루말이 식으로 말아서 충진시킴으로써, 통체(1)가 외부의 충격이나 장애물에 파손되어 해수가 침입할 시 부력이 상실되는 폐단을 방지시킬 수도 있다.Meanwhile, as another embodiment, the inner space 2 is rolled and filled with an air pack sheet 9 made of plastic paper, so that the buoyancy is reduced when the cylinder 1 is damaged by external shocks or obstacles and the seawater invades. It is also possible to prevent the closed end from being lost.
에어팩시트(9)는 도 4에 예시한 바와 같이 2장의 비닐지 사이에 다수의 에어포켓(9a)을 조밀하게 형성한 구조로서 이는 일반 상품의 포장용 에어팩시트(9)를 그대로 전용하여 사용하면 된다.The air pack sheet 9 has a structure in which a plurality of air pockets 9a are densely formed between two plastic sheets as illustrated in FIG. 4. .
도면 부호 10은 양식망을 도시한 것이다.Reference numeral 10 shows a farming net.
이상과 같이 된 본 고안은 연안해역의 각종 양식망 또는 가두리양식장 등의 어망용 부구로 사용하는 것으로 통체(1)는 원통형으로 되어 좌우 캡(4)에 의해 완전 밀폐상태로서 내부 공간부(2)를 형성한 것이므로 이 내부 공간부(2)의 양호한부력기능에 의해 해수 위에 잘 부상되는 것이며, 통체(1)의 외부 행거고리(7) 부위 및 요입홈(8) 부위에 어망로프를 결속하여 어망용 부구로 사용하는 작용효과는 동일하다.The present invention as described above is used as a fishing net for various aquaculture nets or cage farms in coastal waters, and the cylinder 1 becomes a cylindrical shape and is completely enclosed by left and right caps 4, and the inner space part 2 Since it is formed, it is well floated on the sea water by the good buoyancy function of the inner space part 2, and the fishing net is tied to the outer hanger ring (7) part and the recessed groove (8) part of the cylinder (1). The effect of using the tool is the same.
본 고안은 어망용 부구의 구성재질이 저밀도 고강도 EVA발포수지로 구성됨으로써, 해수가 내부 공간부(2)로 잘 침투되지 않아 부력도가 양호하고 외부의 충격에도 통체(1)가 쉽게 파손되지 않으므로 신축력이 극히 양호하여 해수의 운동 또는 장애물에 의해 저항을 받더라도 쉽게 원상복귀되어 내구성, 안정성, 견고성 면에서 매우 유리하다.The present invention is made of low density high strength EVA foaming resin because the material of the fishing net is made of low density, the buoyancy is good because the seawater does not penetrate into the inner space (2) well, and the cylinder (1) is not easily damaged even from the external impact. The elasticity is extremely good, and even if it is resisted by movement or obstacles of seawater, it is easily restored to its original shape, which is very advantageous in terms of durability, stability, and robustness.
뿐만 아니라 EVA재질은 햇볕이나 기후변화에도 잘 약화되지 않아 내후성이 양호한 재질이어서 장기간의 수명을 보장할 수 있을 뿐 아니라, 특히 기존의 스티로폼과 같이 환경오염의 우려도 없어 연안해역의 환경보존에도 일조할 수 있으며 이의 구성에 의한 생산단가도 기존의 플라스틱케이싱을 갖는 스티로폼 부구에 크게 손색이 없으므로 경제성과 실용성을 동시에 만족하는 이점이 있다.In addition, EVA material is not weakened by sunlight or climate change, so it is a material with good weather resistance, which guarantees long-term lifespan, and in particular, there is no concern about environmental pollution like the existing styrofoam, which contributes to environmental preservation in coastal waters. In addition, the production cost by the configuration thereof is also largely inferior to the styrofoam section having the existing plastic casing, there is an advantage to satisfy the economic and practical at the same time.
한편 내부 공간부(2)에 에어팩시트(9)를 충진함으로써 통체(1)의 파손으로 인한 부력저항을 방지할 수도 있다.On the other hand, by filling the air pack sheet 9 in the inner space 2, buoyancy resistance due to breakage of the cylinder 1 can be prevented.
이상과 같이 본 고안은 어망용 부구의 구성을 중공체로 된 저밀도 EVA수지 통체를 구성하므로써 부구로써 요구되는 상품특성인 부력유지, 내구성, 내후성, 내충격성을 충분히 확보하면서 환경공해를 일으키지 않아 연안해역의 각종 어망용 부구로써 매우 실용성을 구비한 고안이라 할 수 있다.As described above, the present invention constitutes a low-density EVA resin cylinder made of a hollow body for the fishing net float, so that the buoyancy, durability, weather resistance, and impact resistance required for the float are sufficiently secured and do not cause environmental pollution. It can be said that it is an invention with very practical use as various fishing nets.
