Abstract
Description
본 발명은 어·패류 채취를 겸한 해저환경 개선장치에 관한 것이다.The present invention relates to an apparatus for improving the seabed environment, which combines fish and shellfish collection.
이를 보다 상세하게 설명하면 해저면에 굴착날과 고압 공기를 분사하여 저질을 뒤엎은 다음 이를 흡입장치로 선체위로 인양하여 햇빛과 산소 및 저질 개선제를 투입, 혼합하여 다시 제자리로 되돌려 줌으로서 해저환경의 개선작업 뿐만 아니라 어·패류를 손상 없이 채취할 수 있는 장치에 관한 것이다.To explain this in more detail, the excavation blade and high-pressure air are sprayed on the sea floor to invert the quality and then lifted it onto the hull by the suction device, adding sunlight, oxygen and the quality improving agent, mixing and returning it back to its place. It also relates to a device that can harvest fish and shellfish without damage.
종래에도 이러한 목적을 달성하기 위한 여러 가지 종류의 장치들이 공지된 바 있으나, 이중에서 형망갈퀴로 저층을 파 뒤엎어 끌고가는 방식은 어·패류의 손상과 부유물에 의해 오히려 해양환경을 오염시키는 폐단이 있고, 압출공기 분사식은 해저면에서 영양분을 함유하고 있는 펄을 분산시켜 해류(민물, 썰물)에 의한 유실로생태계를 파괴하며, 수거망통 방식은 작업능률이 떨어지는 등 경제성이 매우 저조한 결점이 있었던 것이다.In the past, various kinds of devices have been known to achieve this purpose, but the method of digging the bottom layer with a rake in the double has a disadvantage of polluting the marine environment by damage of fish and shellfish and floating matters. In addition, the extruded air jet type disperses nutrients from the sea floor and destroys the ecosystem due to currents (fresh water, low tide), and the collection network method has low economic efficiency, such as poor work efficiency.
본 발명은 상기의 문제점을 해결하고자 안출한 것으로서, 이의 발명 요지는 저속으로 항해하는 선체의 예인로프(1a)에 의해 예인되는 굴착기 몸체(1) 하측 선단에 설치된 굴착날(5)이 해저면을 굴착과 동시에 콤프레샤(11)와 연결된 분사호스(3)의 분사압에 의해 부양하는 물체는 펄물과 함께 흡입닥트(2b)를 통해 흡입호스(2)로 흡입된 후 선체에 설치된 여과망(18) 위로 낙하하면 펄물은 수로(17a)를 통해 혼합통(22)에 유입되고 여과망에 낙하된 낙하물 중에서 어·패류와 분쇄 안되는 물체는 수거하고 해저환경 개선에 분쇄 가능한 물체는 1차 및 2차 분쇄기를 통해 분쇄된 후 이송로(20)를 통해 배출수 혼합통(22)에 투입되면 이에 첨가되는 점·황토, 소·생석회, 맥반석 등의 개선제와 함께 혼합됨에 있어서는 콤프레샤(11)에서 가해지는 고압공기에 의해 속성으로 혼합된 후 배출호스(8)를 통해 해저면에 배출될 때는 콤프레샤(11)에서 가해지는 고압 공기에 의해 압출되어 배출구(9a)를 통해 해저면에 배출된 후 써래판(10)에 의해 투입물이 해저면에 매입되게 한 것이다.The present invention has been made to solve the above problems, the present invention is the excavation blade (5) installed on the lower end of the excavator body (1) towed by the towing rope (1a) of the hull sailing at a low speed to the sea bottom At the same time as the excavation, the object supported by the injection pressure of the injection hose 3 connected to the compressor 11 is sucked into the suction hose 2 through the suction duct 2b together with the pearly water and then onto the filtering net 18 installed in the hull. When falling, the water enters the mixing tank 22 through the water channel 17a, and the objects that are not crushed with fish and shellfish are collected from the falling objects dropped into the filtering network. After being crushed and introduced into the effluent mixing container 22 through the conveying path 20, it is mixed with the improving agent such as point, ocher, bovine, quicklime, and ganbanite, by high pressure air applied from the compressor 11. Attribute When mixed and discharged to the sea bottom through the discharge hose (8) is extruded by the high pressure air applied from the compressor (11) is discharged to the sea bottom through the outlet (9a) and then the input by the harrow plate (10) It was made to buy on the sea floor.

상기와 같이 구성된 본 발명은 어·패류 채취를 겸한 해저바닥 환경 개선장치인바 이의 실시예를 설명하면 다음과 같다.The present invention configured as described above will be described an embodiment of the sea bottom environmental improvement device combined with fish and shellfish collection as follows.
예인로프(1a)에 의해 선체와 연결된 굴삭기 몸체(1)를 해저에 투하하여 바닥에 닿으면 선체를 항진시켜 굴착기 몸체(1)가 시속 2~5노트로 끌어가면서 선체에 장착된 콤프레샤(11)가 고압산소 공기를 분사호스(3)에 연결된 분사관(4)의 다수의 체결식 분사구(4a)를 통해 고압산소 공기를 분사하면 굴착 날(5)로 파헤쳐진 물체들이 펄물과 함께 흡입닥트(2b)를 통해 흡입호수(2)로 흡입된 후 선체에 설치된 여과망(18) 위에 낙하하면 펄물은 수로(17a)를 통해 혼합통(22)에 유입되고 여과망(18)에 걸린 고형물들 중 분쇄가 안되는 쓰레기 등과 어·패류를 분리하여 별도 수거하고, 해저환경 개선에 유익한 분쇄 가능한 물체들은 1차 및 2차 분쇄기(19)(19a) 내로 투입하여 분쇄하되 1차는 조분쇄하고 2차는 미분쇄하여 분쇄가루 이송로(20) 및 수로(17)를 통해 혼압통(22) 내로 유입하게 한다.When the excavator body 1 connected to the hull by the towing rope 1a is dropped on the sea floor and reaches the bottom, the hull is advanced to drag the excavator body 1 to 2 to 5 knots per hour. When the high-pressure oxygen air is injected through the plurality of fastening nozzles 4a of the injection pipe 4 connected to the injection hose 3 by the high pressure oxygen air, the objects dug into the excavation blade 5 are sucked together with the pearl water. After being sucked into the suction lake 2 through 2b) and falling on the filtering net 18 installed in the hull, the water is introduced into the mixing barrel 22 through the water channel 17a and the crushed solids among the solids caught by the filtering net 18 are Separate garbage and fish and shellfish, which are not used, and separate them, and pulverizable objects that are beneficial for improving the seabed environment are put into the first and second grinders (19) and (19a) for grinding, but the first is coarsely pulverized and the second is pulverized. Through the powder conveying path 20 and the channel 17 into the mixing cylinder 22 It makes.
이때 분쇄물은 수로(17a)를 통해 투하된 점·황토, 소석회, 생석회, 맥반석 등의 개선제와 함께 혼합통(22) 내에 유입되면, 격자 형상인 고압분사관(23)의 분사구(23a)에서 분사되는 고압공기와 재차 혼합된 후 배출호스(8)로 배출될 시는 콤프레샤(11)에 연결된 고압분사관(21a)을 통해 혼합통(22)에 혼합된 물체들이 배출구(23a)를 통해 배출호스(8)로 강제 이송된 후 배출관(9)의 배출구(9a)를 통해해저면으로 배출되고 이와 같이 배출되면 배출관(9) 뒤에 장착된 써래판(10)이 자동적으로 배출물을 해저에 경지 정리작업을 하게 되는 것이다.At this time, when the pulverized product flows into the mixing barrel 22 together with the improving agent such as point, loess, slaked lime, quicklime, ganban stone, etc. dropped through the water channel 17a, at the injection hole 23a of the lattice-shaped high-pressure jet pipe 23 When mixed with the injected high-pressure air again and discharged to the discharge hose (8), the objects mixed in the mixing cylinder 22 through the high-pressure injection pipe (21a) connected to the compressor 11 is discharged through the discharge port (23a) After being forcibly conveyed to the hose (8), it is discharged to the sea floor through the outlet (9a) of the discharge pipe (9), and when discharged in this way, the harrow plate (10) mounted behind the discharge pipe (9) automatically arranges the discharge on the seabed. You will be working.
따라서 해저환경을 개선시키고 해저에 서식하는 어·패류에 영양분을 공급하여 어·패류들의 성장을 촉진시키며 또한 어·패류를 훼손시키지 않고 채취할 수 있어 해저면을 오염시키지 않고 기름지게 하기 때문에 어민들의 소득을 증진할 수 있다.Therefore, it improves the seabed environment, supplies nutrients to fish and shellfish inhabiting the seabed, promotes the growth of fish and shellfish, and can be harvested without damaging the fish and shellfish. Can promote.
상기와 같이 본 발명은 어·패류 채취를 겸한 해저환경 개선장치인바, 이는 해저에 침하된 침전물과 펄을 끌어올려 햇빛과 공기를 접하게 하되 분쇄 불가능한 쓰레기와 어·패류는 수거하고 해저환경 개선에 유익한 분쇄 가능한 물체는 1차, 2차로 미분쇄하여 점·황토, 소·생석회, 맥반석 등의 개선제와 함께 혼합하여 본래 장소로 되돌려 줌으로서 해저를 정화시키고 영양분의 공급으로 수산물의 성장촉진은 물론 어·패류의 채취로 어민소득을 증대시키는 효과가 있는 것이다.As described above, the present invention is a device for improving the seabed environment, which combines the collection of fish and shellfish, which raises sediments and pearls submerged on the seabed to contact sunlight and air, but collects non-crushable garbage and fish and shellfish, and is useful for improving the seabed environment. The pulverizable object is first and second finely ground and mixed with the improving agent such as point, loess, bovine, quicklime, and gangue stone to return to the original place to purify the seabed and supply nutrients to promote the growth of marine products The collection of shellfish has the effect of increasing fishermen's income.
