The invention relates to the technical field of ship and ocean engineering, in particular to a two-stage retractable ship bilge keel device which comprises an external bilge keel, a first-stage internal bilge keel, a second-stage internal bilge keel, a lead screw, a sliding rod, a reduction gear and a driving device. The other end of the lead screw is rotationally connected with a sliding rod, the top end of the interior of the second-stage internal bilge keel is connected with the sliding rod, the second-stage internal bilge keel stretches out and retracts back through movement of the sliding rod, and the top end of the interior of the first-stage internal bilge keel is connected with the tail end of the second-stage internal bilge keel. And in the extending or retracting process of the second-stage internal bilge keel, the first-stage internal bilge keel is driven to extend and retract. According to the ship, different sailing conditions and requirements can be met, the stability of the ship can be guaranteed under the severe sea condition, and the internal space of the ship can be better utilized.

    本发明涉及船舶与海洋工程的技术领域,具体涉及一种可二级收放的船舶舭龙骨装置,包括外部舭龙骨、一级内部舭龙骨、二级内部舭龙骨、丝杠、滑杆、减速齿轮、驱动装置,所述驱动装置通过减速齿轮与所述丝杆的一端相连接,所述丝杆的另一端转动连接有滑杆,所述的二级内部舭龙骨内部顶端与滑杆相连接,通过滑杆的移动来实现二级内部舭龙骨的伸出和收入,所述的一级内部舭龙骨的内部顶端与二级内部舭龙骨的尾端相连接,在二级内部舭龙骨伸出或收起的过程中,带动一级内部舭龙骨实现一级内部舭龙骨的伸出和收入。能够应对不同航行条件和要求,在更恶劣的海况下,能够保证船舶的稳定性,且更好地利用了船舶的内部空间。
