The invention relates to a ship gas resistance reduction device and method. The ship gas resistance reduction device comprises a ship body, two U-shaped plates are fixed to the bottom face of the ship body, a bubble plate is attached between the U-shaped plates, a limiting assembly used for fixing the bubble plate is arranged on the U-shaped plate at the tail, and a plurality of gas spraying holes communicating with a straight groove are formed in the bottom face of the bubble plate; the bottom face of the bubble plate is provided with a cleaning mechanism used for brushing the bubble plate to prevent the air spraying holes from being blocked. When the ship gas resistance reduction device is used, the bubble plate is connected with an external gas source device, the gas source device is controlled to convey gas into the bubble plate, the gas forms bubbles through the gas spraying holes, the bubbles gather at the bottom of the ship body to form a gas film, and then resistance of the ship body in the running process is reduced through the gas; the bottom face of the bubble plate can be scrubbed through the cleaning mechanism, it is avoided as much as possible that the bubble plate is soaked in water for a long time, water plants and the like block air spraying holes, and it is guaranteed that the bubble plate can generate a good-quality air film to reduce resistance of the ship body.

    本发明涉及一种船舶气体减阻装置及减阻方法,包括船体,所述船体的底面固定有两个U型板,所述U型板之间贴合有气泡板,尾部的U型板上设有用于固定气泡板的限位组件,所述气泡板的底面开设有多个与直槽连通的喷气孔,所述气泡板的底面设有用于刷洗气泡板避免喷气孔堵塞的清洗机构。该船舶气体减阻装置,在使用时,将气泡板与外界气源装置连接,并控制气源装置向气泡板内输送气体,气体通过喷气孔形成气泡,气泡在船体底部聚集成气膜,进而通过气体降低船体在行驶过程中的阻力,通过清洗机构可以擦洗气泡板的底面,尽量避免气泡板长时间浸泡在水体中使水草等堵塞喷气孔,以保障气泡板能产生质量较好的气膜来对船体进行减阻。
