The invention discloses a dragon paddle propeller. The dragon paddle propeller is a propeller for enabling a ship to advance by applying chain type paddles to act on water in parallel. According to the propeller, a plurality of L-shaped paddles and assemblies are connected with a dragon chain composed of dragon chain links to form chain type paddles, the chain type paddles are installed on the outer side of a ship board, the paddling sections of the chain type paddles are submerged, a driving wheel drives the chain type paddles to rotate and run through a supporting wheel and a driven wheel, and the chain type paddles are supported by a sliding groove and a suspension to sequentially and vertically enter water and run in parallel in water to generate an acting force on the water; and the counter-acting force of water pushes the ship to advance. And the chain type paddle moves horizontally and returns after rowing out of the water surface. According to the large-blade-surface multi-blade dragon-paddle propeller, the acting force of the blade surface to water is increased, and the two sets of dragon-paddle propellers are installed between ship rails of a large triple-hulled ship respectively, so the large-thrust function of the propeller can be achieved. The rotating speeds or reverse rotation of the two thrusters are regulated and controlled respectively, small-radius rapid steering or fixed-point steering of the ship under the rudderless condition can be achieved, and the propeller has the advantages of being large in number of paddles, wide in blade surface, large in thrust and the like.

    本发明公开了一种龙桨推进器,龙桨推进器是运用链式桨叶平行作用于水使船舶前进的推进器。本推进器将若干L形桨叶及组件与由龙链节组成的龙链连接成链式桨叶,装于船舷外侧,链式桨叶划水段没水,主动轮驱动链式桨叶经过支撑轮、被动轮旋转运行,链式桨叶受滑槽和悬架支撑依次垂直入水,在水中平行运行,对水产生作用力,而水的反作用力推动船舶前进。链式桨叶划出水面后平躺运行返回。大叶面多桨叶龙桨推进器加大了叶面对水的作用力,将两套龙桨推进器分别安装于大型三体船船舷之间,可发挥其大推力功能。分别调控两套推进器的转速或反向旋转,可实现船舶在无舵情况下小半径快速转向或定点转向,具有桨叶多、叶面宽、推力大等优势。
