Description
본 고안은 해양에서의 양식장치에 관한 것으로, 특히 유조선이나 벌크선과 같은 대형선박을 이용한 양식장치에 관한 것이다.The present invention relates to aquaculture apparatus in the ocean, and more particularly to aquaculture apparatus using a large vessel such as tankers or bulk carriers.
일반적으로, 가두리양식장은 연근해에 해수가 유/출입되도록 구획그물을 설치하고, 구획그물 내부에서 사료를 사용하여 여러 어종을 기르도록 되어 있다. 이러한 가두리양식장은 풍파의 피해를 최소화하고 관리의 편의를 위하여 내만에 주로 자리잡고 있지만, 연안매립과 임해공단의 건설이 늘어나면서 양식이 가능한 해역이 갈수록 줄어들고, 일부지역은 거의 포화상태로 이르고 있으며, 해양오염이 날로 심각해져 가는 열악한 상황에 처해 있다.In general, cage farms are set up so that seawater flows into and out of the coastal waters, and feedstocks are used to grow various fish species within the compartment. These cages are located mainly in Naman Bay to minimize wind damage and ease management. However, as the coastal landfill and seaside industrial complexes increase, the number of seas where farming is possible decreases, and some areas are nearing saturation. The marine pollution is in a worse situation.
대형선박은 내파성이 있고 이동성이 있어 해양기후에 따라 이동할 수 있을 뿐만 아니라, 밸러스트(105)를 통해 안정된 정박과 이동이 가능하므로, 종래에는 선박의 내부를 개조하여 다수의 구획공간을 만들고, 이 구획공간으로 해수를 유/출입하는 시설을 설치하여 어류를 양식하도록 된 장치가 개발되어 있다.Large ships can be moved in accordance with the ocean climate due to the shock resistance and mobility, as well as stable anchoring and movement through the ballast 105, conventionally remodeling the interior of the ship to create a large number of compartments, this compartment A device has been developed to install fish to flow into and out of the sea.
도 1에 도시된 바와 같이, 종래의 대형선박을 이용한 양식장치는 선박본체(101)의 내부가 다수개로 구획되어 형성되고, 상부벽에 개폐뚜껑(102)과 측벽에 다수의 취수부(103)와 배출부(104)가 형성되며, 상기 취수부(103)와 배출부(104)에서 해수의 출입을 통제하는 개폐밸브, 해수를 강제흡입시키거나 배출시키는 해수취수펌프를 구비하여, 선박본체(101)를 가두리로 사용하고 취수부(103)와 배출부(104)를 통해 표층수를 출입시킴으로써 가두리양식을 할 수 있도록 된 것이다.As shown in Figure 1, the conventional farming apparatus using a large vessel is formed by partitioning a plurality of the interior of the vessel body 101, the opening and closing lid 102 on the upper wall and a plurality of water intake portion 103 on the side wall And a discharge part 104 is formed, the water intake part 103 and the discharge part 104 is provided with an on-off valve for controlling the access of the sea water, and a sea water intake pump for forcibly sucking or discharging the sea water, the ship body ( 101 is used as a cage, and the surface water is allowed to enter and exit through the water intake unit 103 and the discharge unit 104 to form a cage.
상기와 같이 선박본체(101)를 가두리 수조로 직접 사용할 경우 표층수를 그대로 사용하게 되므로 계절에 따른 해수온도의 변화에 대처할 수 없어 동절기에는 저온으로 인해 양식을 할 수 없고, 각기 생존조건이 다른 다양한 어류를 함께 양식할 수 없는 문제점이 있었다.When the ship body 101 is directly used as a cage, the surface water is used as it is, so it is impossible to cope with changes in the seawater temperature according to the season. There was a problem that can not form together.
또한, 표층수를 그대로 유입하여 사용하므로 해양오염에 그대로 노출되어 있으며, 특히 표층수는 심해수에 비해 적조의 영향을 크게 받고 온도변화가 커 양식조건에 적합하지 않은 때가 많았다.In addition, surface water is used as it is, so that it is exposed to marine pollution. Especially, surface water is more affected by red tide than deep sea water.
따라서, 무기영양분이 풍부하며 오염도가 낮은 심해수를 인양하여 사용할 경우 수온이 표층수에 비해 낮아 인양후 곧바로 어류에 공급하게 되면 저온에 의한 폐사가능성이 높은 문제점이 있었다.Therefore, when used in salvaging deep sea water rich in inorganic nutrients and low pollution, when the water temperature is lower than surface water and supplied to fish immediately after salvage, there is a high possibility of death by low temperature.
이에 본 고안은 상기한 바의 제반 문제점들을 해소하기 위해 안출된 것으로, 공급해수의 온도를 적정온도로 상승시켜 어류 양식수조에 공급할 수 있고 내파성이 크며 해양의 기후에 따라 용이하게 이동하여 휴절기 없이 양식할 수 있는 대형선박을 이용한 양식장치를 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve the above problems. The temperature of the supplied seawater can be raised to an appropriate temperature and supplied to the fish farm, and the water resistance is large, and it can be easily moved according to the ocean's climate so that there is no rest period. The purpose is to provide a farming apparatus using a large vessel capable of farming.

도 4에 도시된 바와 같이, 상기 표층수 열교환기(51)는 일측 외주면이 외부로 노출되어 표층수와 열교환하게 되고, 다른 일측 외주면이 상기 방류수 열교환기(52)와 접촉하여 방류수와 열교환하게 됨으로써 표층수 열교환기(51) 내부를 통과하는 공급해수의 수온을 상승시키게 되며, 상기 태양열 집열기구(60)에 의해 다시 수온을 상승시킬 수 있게 되며, 상기 엔진동력부(E)나 발전기의 냉각수와도 열교환하여 수온을 상승시킬 수 있게 된다.As shown in FIG. 4, the surface water heat exchanger 51 has one outer peripheral surface exposed to the outside to exchange heat with the surface water, and the other outer peripheral surface contacts the discharge water heat exchanger 52 to exchange heat with the discharged water. It is possible to increase the water temperature of the supply seawater passing through the inside of the 51, it is possible to increase the water temperature again by the solar heat collector (60), heat exchanged with the coolant of the engine power unit (E) or the generator It is possible to raise the water temperature.
이상에서 설명한 바와 같이 본 고안에 따른 대형선박을 이용한 양식장치에의하면, 선박의 내부에 다수개의 양식수조를 외부와 차단되게 구비하여 내파성이 향상되고 어종마다의 각기 다른 생육조건을 개별적으로 조절할 수 있게 됨으로써 다양한 어종을 양식할 수 있으며, 심해수의 풍부한 영양분과 무공해수를 공급할 수 있고, 저온의 해수를 표층수 및 방류수와 열교환하고 엔진동력부 및 발전기의 냉각수와 열교환시키고 태양열 에너지를 이용하여 가열함으로써 저온의 해수를 어류의 생육에 적당한 수온으로 상승시켜 공급하여 양식어류를 월동시킬 수 있는 효과가 있다.As described above, according to the aquaculture apparatus using a large vessel according to the present invention, a plurality of aquaculture tanks are provided inside the vessel to be blocked from the outside to improve the wave resistance and to individually control different growth conditions for each species. It can grow various fish species, supply rich nutrients and pollution-free water of deep sea water, heat exchange low temperature seawater with surface water and effluent water, heat exchange with coolant of engine power unit and generator, and heat using solar energy By raising the seawater at a suitable water temperature for the growth of fish, it is effective to overwinter the farmed fish.
