The micro-plastics in the ocean can be divided into two major sources of 'primary' micro-plastics and 'secondary' micro-plastics. "virgin" microplastics are fine plastic particles that can be used directly as products or materials in the production of, for example, cleaning agents, facial cleansing milk, and industrial abrasives, exfoliating, pharmaceutical and textile plastic materials. The secondary micro plastic is fine plastic particles formed by decomposing and crushing large marine plastic pollutants layer by layer due to physical, chemical or biological effects in a natural environment. Automobile tire wear, land-source plastic wastes and paint are three main pollution sources of micro plastics in European marine environment. The most important characteristics of the micro-plastics are that the micro-plastics have small particle size and large quantity, and are very easy to be ingested by a series of marine organisms such as marine plankton, benthos, fish, seabird, marine mammal, turtle and the like. Scientists have a fear that the micro-plastics taken up by marine organisms eventually enter the top of the biological chain, human body, through the food chain, and threaten human health.

The fixing frame 55 is installed on the suspension arm 17 of the ship body 16, when the ship body 16 moves forward, the fixing frame 55 drives the shell 5 and the first fixing cylinder 1 to move forward, and water flow sequentially passes through the first filter screen 22 and the second filter screen 42, so that micro plastic is filtered out. When the driving mechanism is started, the driving mechanism drives the second fixing cylinder 3 to slide back and forth on the first fixing cylinder 1, the second filter screen 42 is driven by the second fixing cylinder 3 to be close to and far away from the first filter screen 22, and a first gap 44 formed between the second filter screen 42 and the first filter screen 22 is increased and reduced. Since the filter pore size of first filter 22 is greater than the filter pore size of second filter 42, the resistance encountered by the flow of water through second filter 42 is greater than the resistance encountered by the flow of water through first filter 22.
