본 발명은 선박에 설치하는 어창(魚倉)에 관한 것으로, 특히 선박이 항해할 때 선체주위에 형성되는 해수의 흐름을 이용하여 어창내로 해수가 유입 및 유출되도록 함으로써 항해도중 어창내에서 해수가 자연적으로 순환되도록 하여 보관된 해산물의 생존율을 높이고 신선도가 저하되는 것을 효과적으로 방지하도록 된 어창에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing vessel installed on a ship, and in particular, by using the flow of seawater formed around the hull when the vessel is sailing, the seawater flows in and out of the fishing vessel, thereby allowing the seawater to naturally The present invention relates to a fish tank that is designed to increase the survival rate of the stored seafood and effectively prevent the freshness from being lowered.

일반적으로 양식하거나 어획한 활어 및 각종 해산물을 산지에서 사용지까지 운반하는 선박에는 개구(hatch)를 갖춘 어창이 설치되어 이 개구를 통해 어창내로 해산물을 유입 및 유출시키는 한편 운반도중 해산물이 생존할 수 있도록 물과 산소를 공급해 주도록 되어 있다.In general, vessels carrying live or caught live fish and various seafood from the mountain to the place of use are equipped with a catch, which allows the inflow and outflow of seafood through the opening and the survival of the seafood during transportation. It is supposed to provide water and oxygen.

그런데 이 어창은 대개 물을 저장하는 역할만을 하도록 되어 있고 일정한 크기 이상으로는 제조할 수 없기 때문에 한번 유입된 물은 선체의 유동에 따른 이동외에는 거의 이동 없이 정지해 있게 된다. 따라서 이곳에 저장된 해산물은 물의 흐름에 저항하는 운동을 하지 못하게 되고 선박의 자체 요동, 즉 선체의 횡요나 종요시 어창을 구성하는 벽면에 부딪히면서 충격을 받아 손상을 입게 될 뿐 아니라,운동부족으로 인해 육질의 힘이 떨어지게 된다.By the way, this fish tank is usually only to store water and can not be manufactured more than a certain size, so once the water is introduced, the water is stopped almost without movement except for the movement of the hull. As a result, the seafood stored there is no longer able to resist the flow of water and is damaged due to lack of movement due to lack of movement due to the lack of movement. Will fall.

또한 운반시간이 길어 어창내의 수온이 상승하게 되면 해산물이 생존하는 실제수온과 어창내의 수온이 크게 차이가 나게 되고, 이로 인해 운반시 해산물의 폐사율이 급격하게 증가하거나 신선도가 크게 저하되게 되는데, 이러한 어창에 있어서의 공통적인 문제는 근본적으로 어창내의 환경을 실제 생존환경과 맞추어줄 수 없기 때문에 보관된 해산물의 신선도를 유지하는데에 한계가 있다는 점이다.In addition, if the water temperature rises in the fish tank due to the long transport time, the actual water temperature in which the fish survives and the water temperature in the fish tank are greatly different, which causes a rapid increase in the mortality rate of the seafood during transportation or a significant decrease in freshness. A common problem in the world is that there is a limit to maintaining the freshness of the stored seafood because it cannot fundamentally match the environment in the fishery with the actual living environment.

이에 본 발명은 상기와 같은 문제점을 해결하기 위하여 발명된 것으로, 선박이 항해할 때 선체주위에 형성되는 해수의 흐름과 이에 따른 압력차이로 어창내로 유입된 해수가 자연순환되면서 배출되도록 함으로써 어창내의 환경을 해산물의 실제 서식환경과 근접하도록 조성하여, 어창내의 수온이 상승하는 것을 방지하면서 보관된 해산물이 어창내의 해수의 순환흐름에 따라 운동하도록 유도하여 운반중 해산물의 폐사율을 최소화하고 신선도가 저하되는 것도 효과적으로 방지할 수 있도록 된 어창을 제공함에 그 목적이 있다.Therefore, the present invention was invented to solve the above problems, the seawater flows around the hull formed by the hull and the pressure difference according to the pressure difference when the ship is sailing by allowing the seawater introduced into the fishing window is discharged while the natural circulation It is designed to be close to the actual habitat of the seafood, to prevent the rise of the water temperature in the fishery, and to induce the stored seafood to move according to the circulation of the seawater in the fishery, thereby minimizing the mortality of the seafood during transportation and reducing the freshness. Its purpose is to provide fish ponds that can be effectively prevented.

이하 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 어창이 선박에 설치된 상태를 개략 도시한 사용상태도, 도 2는 본 발명에 따른 어창의 상세도로써, 본 발명은 도면에 도시된 것과 같이, 선체(1)의 소정위치에 유입구(3)와 유출구(4)를 갖춘 어창(5)이 설치되어, 상기 유입구(3)를 통해 어창내로 들어온 해수가 유출구(4)를 통해 배출되므로써 해수가 어창(5)내에서 자연순환되도록 구성되어 있다.1 is a use state diagram schematically showing a state in which the fishing window according to the present invention is installed on the vessel, Figure 2 is a detailed view of the fishing window according to the present invention, the present invention, as shown in the drawings, the predetermined of the hull 1 A fish tank 5 having an inlet 3 and an outlet 4 is installed at the location, so that the sea water is discharged through the outlet 4 through the inlet 3, so that the sea water is discharged through the outlet 4. It is configured to be circulated.

그리고, 상기 유입구(3)는 도 3내지 도 6에 각각 개략적으로 도시된 것과 같이 대략 4각박스형태로 된 본체(6)의 전면부(7)에 선저(8)와 연통되도록 형성되고, 상기 유출구(4)는 본체(6)의 측부에 선측(10)과 연통되도록 형성되어 있다.In addition, the inlet 3 is formed so as to communicate with the bottom 8 on the front portion 7 of the main body 6 in the form of a quadrangular box as schematically shown in Figs. The outlet 4 is formed to communicate with the ship side 10 on the side of the main body 6.

또한, 상기 유입구(3)는 이동관(11)을 사이에 두고 분출부(12)와 분지연결되고, 상기 유출구(4)는 흡입부(13)과 분지연결된 배출관(14)과 연결되며, 이 배출관 (14)은 흘수(draft) 즉, 상기 어창(5)바닥면에서 어창(5)수면까지의 높이를 초과하는 지점을 통과하여 선체가 물에 잠겨 있는 부분보다 낮은 선측(10)에 연결되도록 설치되어 있다.In addition, the inlet 3 is branched to the ejection part 12 with a moving pipe 11 interposed therebetween, and the outlet 4 is connected to the outlet pipe 14 branched to the suction part 13, which is discharged. 14 is installed so that the hull is connected to the lower side 10 than the portion where the hull is submerged by passing through a draft, that is, a point exceeding the height from the bottom of the fishing insole 5 to the surface of the fishing intake 5. It is.

또한, 상기 분출부(12)와 흡입부(13)는 각각 봉 형태를 하고서 그 길이방향을 따라 다수의 배출공(15)과 흡입공(16)이 형성되고 어창(5)내에서 서로 대향되는 위치에 부착되어 있는 바, 즉 상기 분출부(12)는 본체(6)의 상부에 설치되는 반면 상기 배출관(14)은 선체(1)의 선측(10)에 설치되어, 상기 유입구(3)로 들어온 해수가 이동관(11)을 경유하여 분출부(12)에 형성된 배출공(15)을 통해 어창(5)내로 유입됨과 동시에 어창(5)으로 들어온 해수는 흡입공(16)으로 유입되어 배출관(14)을 경유하여 유출구(4)로 빠져나가게 됨에 따라 해수가 어창(5)내에서 자연스럽게 유통되게 된다.In addition, each of the ejection portion 12 and the suction portion 13 has a rod shape, and a plurality of discharge holes 15 and suction holes 16 are formed along the longitudinal direction thereof and are opposed to each other in the fish tank 5. It is attached to the position, that is, the ejection portion 12 is installed on the upper portion of the main body 6 while the discharge pipe 14 is installed on the side 10 of the hull 1, the inlet 3 The incoming seawater is introduced into the fishing window 5 through the discharge hole 15 formed in the ejection part 12 via the moving pipe 11, and the seawater entering the fishing window 5 is introduced into the suction hole 16 and discharged to the discharge pipe ( As it exits to the outlet 4 via 14), the seawater is naturally distributed in the fish tank 5.

한편, 상기 이동관(11)의 소정위치에는 역지밸브(17)가 설치되어 선박의 항해속도가 느려졌을 때 유출구(4)로 해수가 역류되는 것을 방지함으로써 어창(5)내에서 해수의 순환이 방해받는 것을 방지하도록 되어 있고, 상기 유입구(3)에는 선박의 진행방향으로 스쿠프(scoop)가 형성되어 선박이 진행할 때 해수가 자연스럽게 유입되도록 되어 있다.On the other hand, a check valve 17 is installed at a predetermined position of the moving tube 11 to prevent seawater from flowing back to the outlet 4 when the sailing speed of the vessel is slowed, thereby preventing the circulation of seawater in the fish tank 5. In order to prevent receiving, the inlet (3) is formed with a scoop (scoop) in the traveling direction of the ship so that the seawater naturally flows when the ship proceeds.

다음에는 상기와 같이 구성된 어창내에서 해수가 유동하는 원리를 첨부된 예시도면에 의거 상세하게 설명한다.Next, the principle of the sea water flow in the fishing window configured as described above will be described in detail based on the accompanying drawings.

본 발명에 따른 어창(5)은 선체의 형상에 따라 선체주위에 형성되는 압력이 증가하는 부분 및 상대적으로 압력이 감소하는 부위에 각각 유입구(3) 및 유출구 (4)를 형성하여, 유입구(3)를 통해 흘러들어온 해수가 이동관(11)을 따라 이동하여 분출부(12)를 통해 어창(5)내로 해수를 분사하게 되고, 분사된 해수는 배출관(14)을 경유하여 유출구(4)를 통해 선체(1)외측으로 빠져나가도록 함으로써 어창(5)내에서 해수가 자연스럽게 유동되도록 되어 있다.The fishing window 5 according to the present invention forms the inlet port 3 and the outlet port 4 at the portion where the pressure is formed around the hull according to the shape of the hull and the portion where the pressure decreases, respectively, the inlet port 3 Seawater flows through the moving pipe 11 is moved along the moving pipe (11) to inject the seawater into the fish tank (5) through the ejection portion 12, the injected seawater through the outlet (4) through the discharge pipe (14) By letting out the hull 1, the seawater flows naturally in the fish tank 5. As shown in FIG.

즉, 도 3내지 도 6에 도시된 것과 같이 유입구(3)로 흘러들어온 해수가 선박의 항주(航走)로 형성되는 압력차이로 이동관(11)을 따라 이동하여 분출부(12)에 형성된 배출공(15)을 통해 어창 수면 상부에 해수를 분사시키게 되며, 분사된 해수는 흡입공(16)으로 흡입되어 배출관(14)을 경유하여 유출구(4)로 빠져나가게 되므로써 어창(5)내의 해수가 일정수위를 유지할 수 있게 된다.That is, as shown in FIGS. 3 to 6, the seawater flowing into the inlet port 3 moves along the moving pipe 11 with a pressure difference formed by the ship's Hangzhou, and is discharged in the ejection part 12. The seawater is injected into the upper surface of the fish lance through the ball 15, and the injected seawater is sucked into the suction hole 16 and exits to the outlet 4 through the discharge pipe 14 so that the seawater in the fish tank 5 can be discharged. It is possible to maintain a certain level.

그리고 선박의 항주속도가 감소하여 배출관(14)내의 압력이 선체(1)주변의 압력보다 감소되더라도 상기 역지밸브(17)로 인해 어창(5)내로 해수가 역류하는 것이 방지되므로 어창(5)내에서 해수가 자연순환되는 것을 유지할 수 있게 된다.In addition, even if the pressure in the discharge pipe 14 decreases than the pressure around the hull 1 due to a decrease in the speed of the ship, the check valve 17 prevents the backwater of the seawater into the fish tank 5, thereby preventing the flow of water into the fish tank 5. At this point, it is possible to maintain the natural circulation of sea water.

한편, 해수는 상기 유입구(3)에 형성된 스쿠프로 인해 제로(zero)에 가까운 속도로 유입됨에 따라 유입압력이 최대한 증가되어 배출공(15)으로 분출되는 해수의 분출에너지를 충분하게 얻을 수 있게 되고, 상기 유입구(3)와 유출구(4), 이동관(11) 및 배출관(14)의 길이와 높이등을 적절하게 조절하면 어창(5)내의 순환유속을 해산물이 실제 생존하는 환경과 유사하게 재현할 수 있게 된다.On the other hand, the seawater is introduced at a speed close to zero due to the scoop formed in the inlet (3), the inlet pressure is increased as much as possible to obtain a sufficient ejection energy of the seawater to be discharged to the discharge hole (15) By properly adjusting the length and height of the inlet (3) and the outlet (4), the moving pipe (11) and the discharge pipe (14), the circulation flow rate in the fish tank (5) can be reproduced similar to the environment in which the seafood actually survives. It becomes possible.

또한, 상기 배출공(15)의 구경을 적절하게 조절하여 분출압력을 조절하면 어창수면위로 해수를 분사할 수 있으며, 분사될 때 산소공급의 효과도 있게 되므로 별도로 산소공급장치를 사용할 필요가 없게 된다.In addition, by controlling the ejection pressure by appropriately adjusting the aperture of the discharge hole 15, it is possible to inject seawater on the surface of the fish window, there is no need to use an oxygen supply device because there is also an effect of oxygen supply when injected. .

이상 설명한 것과 같이 본 발명에 의하면, 선박이 항해할 때 선체주위에 형성되는 해수의 흐름과 이에 따른 압력차이를 이용하여 어창내로 유입된 해수가 자연적으로 순환되면서 배출되도록 하여 어창내의 환경을 해산물의 실제 서식환경과 근접하게 만들어줌으로써, 어창내의 수온이 상승하는 것을 방지하면서 보관된 해산물이 어창내의 해수의 순환흐름에 따라 운동하도록 유도하여 운반중 해산물의 폐사율을 최소화하고 신선도가 저하되는 것도 최소화하는 잇점이 있다.As described above, according to the present invention, by using the flow of seawater formed around the hull and the pressure difference according to the present invention, the seawater introduced into the fishery is naturally circulated and discharged so that the environment in the fishery can be discharged. By bringing it close to the habitat environment, it prevents the water temperature from rising in the incubation and induces the stored seafood to move according to the circulating flow of the seawater in the incubation, minimizing the mortality of the seafood during transportation and minimizing the freshness. have.
