APPARATUS OF COLLECTING MICROPLASTIC AT SURFACE WATER

The present invention relates to an apparatus of collecting microplastics at surface water. The apparatus of collecting microplastics at surface water according to one aspect of the present invention includes: an outer cylinder having an accommodating space therein and opened at the bottom of the accommodating space; a buoyant body installed in the outer cylinder and having buoyancy; an inner cylinder installed in the accommodating space and having a water passage hole formed in a vertical direction to allow water to pass through the water passage hole up and down according to the vertical movement of the outer cylinder by wave force; a filter installed in the inner cylinder to filter microplastics contained in the water passing through the water passage hole; and a weight installed in the inner cylinder to apply a load to the inner cylinder. Accordingly, the apparatus for collecting microplastics at surface water can introduce seawater based on wave force without a separate driving source and discharge the seawater that has passed through the filter. 본 발명은 표층수 미세 플라스틱 수거 장치에 관한 것으로 본 발명의 일면에 따른 표층수 미세 플라스틱 수거 장치는 내부에 수용공간이 구비되고 수용공간의 하부가 개방된 외부실린더, 외부실린더에 설치되고 부력을 가지는 부력체, 수용공간에 설치되고 물통과공이 상하로 관통되어 파력에 의한 외부실린더의 상하운동에 따라 물이 물통과공을 상하로 통과하도록 하는 내부실린더, 내부실린더에 설치되어 물통과공을 통과하는 물에 포함된 미세 플라스틱을 걸러내는 거름망 및 내부실린더에 설치되어 내부실린더에 하중을 가하는 중량물을 포함한다.
