A bionic cuttlefish underwater propeller belongs to the technical field of bionic propellers and is characterized in that a duckbilled one-way valve II, a rubber elastic part II and a dielectric elastomer are arranged front and back and are fixedly connected, openings of the two duckbilled one-way valves face forwards, and the dielectric elastomer is composed of a rubber elastic part III and two layers of VHB4910 films. The second layer of VHB4910 film is adhered to the surface of the rubber elastic piece III, and the power line is fixedly connected between the second layer of VHB4910 film; after the second layer of VHB4910 film is electrified, the thickness of a rubber elastic part III is reduced, the surface area is increased, the rubber elastic part III expands outwards, otherwise, the rubber elastic part III retracts, and the bionic cuttlefish underwater propeller moves in water in a circulating mode; the propeller can effectively solve the problems that an existing propeller is complex in structure, poor in concealment and large in noise, and is simple in structure, easy and convenient to operate, low in cost and convenient to popularize.

    一种仿生乌贼水下推进器属仿生推进器技术领域,本发明的鸭嘴单向阀Ⅱ、橡胶弹性件Ⅱ、介电弹性体、橡胶弹性件Ⅰ和鸭嘴单向阀Ⅰ前后排列并固接,二鸭嘴单向阀开口朝前,介电弹性体由橡胶弹性件Ⅲ和二层VHB4910薄膜组成,二层VHB4910薄膜粘接于橡胶弹性件Ⅲ表面,电源线固接于二层VHB4910薄膜之间;二层VHB4910薄膜通电后使橡胶弹性件Ⅲ厚度减小表面积增加,橡胶弹性件Ⅲ向外舒张,反之缩回,循环往复实现仿生乌贼水下推进器的水中移动;本发明能有效解决现有的推进器结构复杂,隐蔽性差,噪声大的问题,且结构简单、操作简便,成本低廉,便于推广。
