Abstract

The invention discloses an anti-corrosion structure of an air supply system for an air layer drag reduction ship. The anti-corrosion structure comprises a ventilation pipeline with an opening connected to a ship bottom plate, an opening/closing unit and a pressure stabilizing cavity. The opening/closing unit is arranged on the ventilation pipeline. The pressure stabilizing cavity is formed betweenthe ventilation pipeline and the ship bottom plate, the first end of the pressure stabilizing cavity communicates with an opening of the ventilation pipeline, and the second end of the pressure stabilizing cavity is fixedly connected with the ship bottom plate. And an air injection part corresponding to the pressure stabilizing cavity is arranged on the ship bottom plate and used for injecting air in the pressure stabilizing cavity. The pressure stabilizing cavity and the ventilation pipeline form air space when the opening/closing unit is in a closed state, and communication between the airspace and the interior of the ship body is blocked. When the air supply pipeline does not convey air, the opening/closing unit is closed, seawater is limited in the air space and cannot flow to otherplaces, and the seawater is prevented from corroding other places of the ship body.

本发明公开了一种用于气层减阻船的供气系统防腐结构，包括开口连接于船底板上的通气管路、开/闭单元和稳压腔。开/闭单元设置在通气管路上。稳压腔设于通气管路和船底板之间，稳压腔的第一端与通气管路的开口连通，稳压腔的第二端与船底板固连。船底板上设有与稳压腔相对应的喷气部，用于喷出稳压腔内的气体。稳压腔、通气管路在开/闭单元闭合状态下形成一气体空间，阻隔了气体空间和船体内部的连通。供气管路不输送气体时，开/闭单元闭合，海水被限制在气体空间，不会流到其他地方，防止海水对船体其他地方的腐蚀。
