The oil pollution adhering to the separation belt will be scraped off under the action of the fixed scraper and flow into the recovery box along the baffle inclined plate. The design of the baffle inclined plate can also effectively prevent the oil pollution already collected in the recovery box from splashing out.

[0016] In addition, through the setting of the adjustment mechanism, the adjustment of the depth of the box body immersed in seawater is realized. When the adjustment plate is pulled downwards, the adjustment plate will slide through the cooperation of the fixed column and the sliding column. The movement of the sliding column will drive the fixed plate and the positioning convex block to move. Under the action of the tension spring, the positioning convex block closely adheres to the inner side of the positioning groove, thereby realizing the positioning of the adjustment plate. At the same time, after the driving motor is started, the motor will drive the threaded shaft to rotate through the meshing of the bevel gear set. The rotation of the threaded shaft will push the rotating ring and the airbag to move through the threaded connection with the threaded rod. By adjusting the position of the airbag, the immersion depth of the box body in seawater can be changed, so as to clean up marine garbage at different depths, improving the cleaning efficiency and the adaptability of the equipment.

[0017] In addition, through the setting of the above mechanism, not only the efficient separation of oil stains on the sea surface is realized, but also the function of adjusting the immersion depth of the box body is possessed, which not only improves the cleaning efficiency but also enhances the applicability of the equipment.
