The invention relates to the technical field of ship and ocean engineering, in particular to a ship retractable bilge keel device mounted on a ship side, which consists of a bilge keel rotating mechanism and a bilge keel retractable system. The bilge keel rotating mechanism is composed of a ship side lower steel plate, a rotating shaft and an electric control sliding rail. The bilge keel folding and unfolding system is composed of a hydraulic push rod, a guide rail and a ship side upper steel plate. Due to the expandable bilge keel structure, the ship can more flexibly cope with different navigation conditions and requirements. When the ship navigation sea condition is bad or the requirement for stability is high, the bilge keel can be unfolded, damping is increased, rolling is reduced, and stability is enhanced; when small storm waves exist or a ship is limited to travel in a channel, the bilge keel is retracted, the hull is prevented from being damaged by grounding, collision and the like, the molded line of the underwater part of the ship is not affected after the bilge keel is retracted, and the quickness of the ship is not affected by additional resistance.
本发明涉及船舶与海洋工程的技术领域,具体涉及一种安装在船侧的船舶收放式舭龙骨装置,该装置由舭龙骨转动机构和舭龙骨收放系统两部分组成;其中,所述舭龙骨转动机构由船侧下钢板、转轴、电控滑轨组成;所述舭龙骨收放系统由液压推杆、导轨、船侧上钢板组成。可展开的舭龙骨结构形式,使得船舶能够更加灵活地应对不同航行条件和要求。当船舶航行海况恶劣或者对稳性要求较高时,可以展开舭龙骨,增大阻尼,减小横摇,增强稳性;面对小风浪的情况或者限制船舶行进航道时,则收回舭龙骨,防止触底、碰撞等损坏船体,并且收回后对船舶水下部分的型线不会产生影响,不额外产生阻力进而影响船舶的快速性。
