Device for damping at source the wave action of a floating structure such as a boat or river train by an on-board pneumatic breakwater system

摘要

The device has front and rear pneumatic equipments (8, 10, 9, 11) comprising a perforated controller that is supplied with pressurized gas by a gas source. The perforated controller produces a curtain of fine gas bubbles (12.10, 12.11) when the perforated controller is immersed such that the gas bubbles attenuate springing waves when a depression of a floating structure i.e. river convoy (1), moves at a speed (4) between banks (3, 14) of a waterway (2). Arms move one of the front pneumatic equipments between a folded up position and a deployed position.
