The specific embodiment
Below in conjunction with the drawings and specific embodiments to a kind of monotubular described in the utility model under water the foreign matter capturing device be further described.
As depicted in figs. 1 and 2, a kind of monotubular described in the utility model under water foreign matter capturing device appearance and size only for about 360mm * 610mm * 1800mm.
This monotubular foreign matter capturing device is under water connected to form by passage 6 and a big tube 5 by little tube 8 bottoms.Element kit 7 is placed in the little tube 8, and element kit 7 can be polyester non-woven fabric filter core or stainless steel filter cylinder.
