Abstract:
PURPOSE: A multipurpose mooring device is provided to improve safety of the mooring device by preventing shock delivered to a mooring pipe. CONSTITUTION: A multipurpose mooring device(1) comprises multi-rings(10) and mooring bands(20). The multi-rings are installed in parts where inner buoyant pipes and outer buoyant pipes are crossed for connecting buoyant pipes(5) each other. The mooring bands are installed on the mooring pipes for connecting mooring ropes(7).
Abstract:
The present invention comprises a display unit having a holding unit fixed at a flag installation rod and an LED flickering element. The present invention generates electricity by using a solar battery to provide the LED, which requires for low energy, with the electricity and forms a reflection panel in a position facing the LED to effectively spread the light for recognizing fishing equipment and locations of fish farms day and night. The display unit is produced by a watertight process to prevent each component installed inside the display unit from being exposed to the outside. The holding unit and the display unit are connected by a swivel capable of rotating 360 degrees, thus, the display unit having the LED flickering element can be maintained horizontally on the water surface even under waves and winds.

본 고안은 낙지 어획용 통발에 관한 것으로서, 더욱 상세하게는 통수공이 형성된 몸통튜브의 하단부 내측으로 깔때기형 트랩이 삽입 설치된 통발에 있어, 상기 통수공을 직사각 형태의 슬릿(Slit) 구멍으로 형성시키는 한편, 몸통튜브의 상단부에는 원판 형태의 개폐식 뚜껑을 설치함으로서, 좁은 틈을 찾아 측면으로 기어 들어가는 게의 습성에 따라 몸통튜브의 내부로 투입된 미끼용 게의 다리 부분이 통수공을 통하여 외부로 최대한 노출될 수 있도록 하고, 이로 인하여 미끼에 의한 낙지의 유인 및 어획성능을 크게 향상시킬 수 있도록 하는 동시에, 어획된 낙지의 다리 부분이 몸통튜브의 외부로 빠져 나오지 않도록 함에 따라, 어획된 낙지의 어체 회손을 최소화시켜 상품가치를 보장할 수 있도록 하며, 통발로부터 낙지를 빼내는 작업 또한 개폐식 뚜껑을 이용하여 보다 더 신속하고 용이하게 수행할 수 있도록 한 튜브형 낙지 어획용 통발에 관한 것이다.
Abstract:
PURPOSE: A self-generation type light buoy is provided to light in the most of environments where waves exist by using the vertical kinetic energy of the waves as the power for self-generation. CONSTITUTION: A self-generation type light buoy(10) comprises a light emitting part(11), a power part(12), and a floating member(13). The light emitting part comprises at least one LED. The power part supplies power to the LED. The floating member contains the light emitting part and the power part and provides buoyancy to the light buoy.
Abstract:
PURPOSE: A fodder floating system is provided to prevent water pollution inside a floating fish cage, and to reduce the waste of management costs. CONSTITUTION: A fodder floating system for a floating fish cage using nano-microbubbles comprises an oxygen dissolving water supplier(200) formed on one side of an upper plate; a first supply line(210) where the oxygen dissolving water which is supplied from the oxygen dissolving water supplier flows in; a second supply line(220) where the oxygen dissolving water which is supplied from the first supply line flows in; and a spraying device(230) installed at the second supply line which sprays the 10-30nm nano-microbubbles to be attachable to the fodder.
Abstract:
PURPOSE: A fishing lamp using an LED is provided to emit a constant amount of light even though a vessel shakes by waves. CONSTITUTION: A fishing lamp using an LED comprises a housing(110), a water flow pipe(120), and a fishing lamp module(140). The housing protects the fishing lamp module. The water flow pipe is combined with the housing and is exposed to the outside of the housing. The fishing lamp module is combined with the water flow pipe and comprises a pipe combining unit, a plurality of wing units, and a flange unit. The water flow pipe is inserted into the pipe combining unit. The wing unit is extended from the exterior of the pipe combining unit. An LED unit is combined with the flange unit.
Abstract:
PURPOSE: A bio-decomposable rope net for fishing ground and a manufacturing method thereof are provided, which can realize an optimal rope net for the fishing ground. CONSTITUTION: A manufacturing method of a bio-decomposable rope net for fishing ground comprises a pellet drying step(S1) for drying pellets to less than 0.0005% of moisture through vacuum drying; a melting and extruding step(S2) for extruding pellets and melting and extruding pellets; a filament discharge step(S3) for forming the molten resin into the fiber filament; a filament cooling step(S4) for air-cooling the fiber filament; a filament winding step(S5) for winding the fiber filament on a bobbin; and a rope net manufacturing step(S6) for manufacturing the rope net using a bunch of fiber filaments.
