Abstract:
본 발명은 초망어업의 조업 자동화장치에 관한 것으로 특히 초망을 기계적 장치에 의해 투, 양망함으로써 작업인력 및 경비 그리고 작업자의 체력소모를 줄이는 한편 안전조업과 함께 작업환경의 개선 및 어민의 소득증대에 기여하고자 한다. 본 발명은 그물의 자동투하 및 인양장치로써 외드럼 및 쌍드럼권양기(20)(30)를 구비하여 이에 작은챗대줄, 그리고 큰챗대줄 및 쪽대그물연결줄을 권취한 각 드럼(21)(31)(32)을 구성하고 납추(80)를 수중으로 내려 그물을 전개시키는 그물전개기(40), 그리고 그물살을 선내로 끌어올리는 양망기(50)등 그 관련 구성으로 이루어진 일련의 조업 자동화장치를 제공 하고자 한다. 본 발명은 상기 각 드럼을 일단의 유압모터로 구동시켜 작은챗대줄 및 큰챗대줄을 풀어주거나 권취하여 그물을 기계적으로 투 양망하는 한편 그물전개기에 의한 그물의 전개수단을 보조하고 양망기를 이용하여 포획된 어획물을 극히 용이하게 선내로 끌어 올리게 된다. 본 발명은 상기한 각 드럼의 불필요한 구동을 제어하기 위한 전자브레이크(25)(35)의 구성 그리고 출항 및 귀항시 챗대의 선수쪽 이동을 위한 그물전개기의 회동 및 절첩구조 또 그물의 용이한 양망을 위한 양망기 드럼의 고무피복층(52)등이 부가적으로 구성된다.
Abstract:
PURPOSE: A work automating device of a scoop net fishing is provided to automate a work by casting a scoop net by a mechanical device using in an anchovy catch. CONSTITUTION: The work automating device comprises:a drum(21) in the lower part of a mast(11) of a fishing boat(10) installing one outer drum winch(20) and a pair of drum winches(30) having two drums; a net unfolding device(40) installed in the starboard stem of the fishing boat(10); a net hauler(50) installed in the right gunwale; common guide rollers(12)(13)(14) equipped in the upper part of the mast(11); a small net bar rope of a net(60) in the drum(21) of the outer drum winch(20), and a large net bar rope(62) and a landing net connecting rope(71) connected in a landing net(70) wound in both drums(31)(32).
Abstract:
PURPOSE: A method for restoration and preservation of an immersion type biological sample for permitting maintenance of a body color of a biological sample for a long period time and restoration of a body color of a decolored biological sample to its original state and then preservation is provided which permits semipermanent preservation of the body color of the biological sample and reutilization of conventional biological samples without the necessity of fabrication of a new biological sample. CONSTITUTION: A body color composition for restoration and preservation of an immersion type biological sample contains 0.3 to 2 parts by weight of benzyl alcohol, 0.3 to 2 parts by weight of sodium chloride, 15 to 25 parts by weight of formalin and 5 to 15 parts by weight of glacial acetic acid, based on 100 parts by weight of water. The restoration method comprises: preparing a body color composition similar to the body color of a biological sample; dyeing the biological sample with the body color composition; fixing the biological sample; and immersing the fixed biological sample in a preservation liquid.
