Modular barrage to collect natural and man-made pollutants from water surfaces has parallelpiped frames with floats, guides and retaining nets

摘要

The barrage is constructed from a series of modules (1), each having a parallelepiped frame (2) of metal tubing with a central channel (6) and side floats (7a, 7b), external guides (8) on the front of the frame and a retaining net (9) for pollutants on the back. The retaining net is in two parts - an inner retaining net (10a) with a small mesh to retain pollutants, and an outer net (10b) with a larger mesh for manoeuvring the inner one.
