Abstract

SOLUTION: An underwater housing device includes a housing 1 and a gas source 3 connected to the housing. The housing has one open end face 2 that faces an underwater surface. A gap 7 is formed between the open end face and the underwater surface. A rotating water flow is formed inside the housing. The gas source supplies air into the housing. The rotating water flow prevents the air from escaping through the gap between the housing and the underwater surface, thus the underwater housing device forms a water-free space on the underwater surface.EFFECT: The device is applicable to underwater wall surfaces at any inclination angle and can effectively establish a water-free space even if there is a gap or no contact between the underwater housing device and an underwater surface, to demonstrate excellent applicability.SELECTED DRAWING: Figure 5
