A multi-joint connecting rod, an umbrella-shaped structure and an outer elastic skin are connected between a water absorbing structure and a water spraying structure, a water absorbing opening is formed in the water absorbing structure, a water spraying opening is formed in the water spraying structure, and an electric push rod is arranged in the water spraying structure; the water suction port and the water outlet drive the multi-joint connecting rod, the umbrella-shaped structure and the outer elastic skin together through the electric push rod to complete the action of simulating cuttlefish water suction and water spraying. A similar umbrella-shaped opening and closing mechanism is adopted, the volume change of the cavity and the change of the pressure difference between the interior and the exterior of the cavity are achieved, and the water absorption and drainage process is completed; the mode that the head laterally absorbs water and the tail axially sprays water is adopted, and maximization of the propelling efficiency is easily achieved; the same set of driving device is adopted, and interlocking of a water suction opening and a water spraying opening and opening and closing actions of an expansion support and a contraction support are achieved through mechanism design. The direction steering engine is adopted as the water injection nozzle, vector control over the propelling direction of the propeller is achieved, and therefore high maneuverability and flexible operability of equipment are improved.

    本发明涉及一种伞状容积式仿生推进器,吸水结构与喷水结构之间连接多关节连接杆及伞状结构和外弹性蒙皮,吸水结构中设有吸水口,喷水结构中设有喷水口,电动推杆置于喷水结构中,吸水口、出水口一起由电动推杆驱动多关节连接杆及伞状结构和外弹性蒙皮完成模仿乌贼吸水喷水的动作。本发明采用类似伞状开合的机构,实现腔体的容积变化和腔体内外压差的变化,完成吸水和排水过程;采用头部侧向吸水、尾部轴向喷水的方式,易于实现推进效率最大化;采用同一套驱动装置,通过机构的设计实现吸水口和喷水口互锁,以及膨胀和收缩支架的开合动作;喷水口采用方向舵机,实现推进器的推进方向的矢量控制,从而提高设备的高机动性和灵活操作性。
