The invention relates to a retractable bilge keel which comprises a bilge keel body, a driving device, a connecting mechanism, a storage mechanism and a slide way, the driving device is arranged in a ship body, the connecting mechanism and the slide way are arranged in the storage mechanism, and the bilge keel can be completely placed in the storage mechanism in a retracted state. The output end of the driving device is connected with the connecting mechanism, the output end of the connecting mechanism is connected with the bilge keel, the connecting mechanism can slide on the sliding way, the bilge keel can stretch out of the storage mechanism in the stretching-out state, and the main body part of the bilge keel is arranged outside the ship body. Extension and contraction of the bilge keel can be adjusted based on the size of sea waves, the bilge keel can be retracted on a calm sea surface while the effect of the bilge keel is guaranteed, and therefore energy loss of a ship body can be reduced.
本发明涉及一种可收放的舭龙骨,包括:舭龙骨、驱动装置、连接机构、存储机构和滑道,所述驱动装置设置于船体内部,所述存储机构内部设置所述连接机构和滑道,且所述舭龙骨在收缩状态下能够完全置入存储机构内,所述驱动装置的输出端与连接机构相连,所述连接机构的输出端与舭龙骨相连,所述连接机构能够在滑道上滑动,所述舭龙骨在伸出状态下能够伸出于存储机构且其主体部分置于船体外部。本发明能够基于海浪的大小进行舭龙骨的伸出与收缩的调节,在保证舭龙骨作用的同时,也能在平静的海面上将其收回,以便于减少船体能量的损耗。
