The catamaran propelling device comprises a catamaran body (1), paddle propelling devices (2), a deck (3), paddles (4), gears (5), chains (6), rollers (7), inner chain plates (8), sleeves (9), pin shafts (10), outer chain plates (11) with paddles and outer chain plates (12) with paddles. The paddles are driven through rotation of the chain, and the catamaran is pushed to move through interaction of the paddles and water. Water flow between the two ship bodies can be adjusted and rectified, the flowing state of the water flow is changed, and resistance received by the catamaran is reduced. Due to the action characteristics of the paddles, cavitation bubbles can be reduced, the propulsion efficiency is improved, and the navigation stability and the operation performance of the ship are improved.

    本发明公开了一种双体船推进装置,包括船体(1)、桨叶推进装置(2)、甲板(3)、桨叶(4)、齿轮(5)、链条(6)、滚子(7)、内链板(8)、套筒(9)、销轴(10)、带桨叶的外链板(11)和外链板(12)。本发明通过链条的转动带动桨叶,通过桨叶与水的相互作用,推动双体船的运动。可以对两船体间的水流进行调节和整流,改变水流的流动状态,减少双体船收到的阻力。由于桨叶的作用特点,能够减少空泡的产生,提高推进效率,提高船舶的航行稳定性和操作性能。
