Submergible cleaning system

摘要

A submergible cleaning system (1) for cleaning an underwater hull surface (3) of a vessel while the vessel is afloat or an offshore facility, the cleaning system (1) comprising a housing (2) comprising a top face (3) and side faces (4) having edges (5) and an open bottom face, the edges (5) and bottom face being arranged opposite the hull surface (3), and the further comprising a rotary disc (6) having a plurality of nozzles (7) arranged around a periphery (30) of the rotary disc, the nozzles facing the hull surface (3), rolling spacing devices (8) for providing a predetermined first gap (9) between the rotary disc (6) and the hull surface (3), a suction device (10) fluidly connected to an outlet (11) arranged in the housing (2) for providing a negative pressure within the housing (2), a pressurizing device (12) fluidly connected with the nozzles (7) for providing a high pressure fluid to the nozzles (7), whereby the nozzles (7) are adapted for discharging fluid under high pressure against the hull surface (3) for cleaning, wherein the housing (2) further comprises a shroud (13) at least partly arranged between the rotary disc (6) and the housing (2), whereby a chamber (14) is provided between the housing (2) and the shroud (13), the chamber (14) being in fluid communication with the suction device (10). The present invention also relates to a vessel or workboat comprising such submergible cleaning system and to use of such submergible cleaning system.

主权项

1. A submergible cleaning system for cleaning an underwater hull surface of a vessel while the vessel is afloat or an offshore facility, the cleaning system comprising:
a housing comprising a top face and side faces having edges and an open bottom face, the edges and bottom face being structured to be arranged opposite a hull surface, and the housing further comprising:
a rotary disc having a plurality of nozzles arranged around a periphery of the rotary disc, the nozzles being positioned to face the hull surface,rolling spacing devices for providing a predetermined first gap between the rotary disc and the hull surface, a suction device fluidly connected to an outlet arranged in the housing for providing a negative pressure within the housing, a pressurising device fluidly connected with the nozzles for providing a pressurized fluid to the nozzles, whereby the nozzles are adapted for discharging fluid under pressure against the hull surface for cleaning,
wherein the housing further comprises a shroud at least partly arranged between the rotary disc and the housing, whereby a chamber is provided between the housing and the shroud, the chamber being in fluid communication with the suction device.
