Heart-imitating underwater propeller based on IPMC combined muscles

Abstract

The invention aims to provide a heart-imitating underwater propeller based on IPMC combined muscles. The underwater propeller is composed of IPMC combined muscle power components, a self-cleaning filter head, atrium pressure chambers, ventricle pressure chambers, a jet flow propelling part and a jet flow direction adjusting part. The self-cleaning filter part comprises an outer cover composed of filtering holes, a layer of filter screen is arranged inside, and a reflux hose is connected with a control valve and a three-way flow-splitting head; according to the atrium pressure chambers and the ventricle pressure chambers, the structure of each atrium pressure chamber III is mainly formed by a water inlet partition plate and the IPMC combined muscles, a piston on each atrium pressure chamber is provided with a water communicating one-way valve, each ventricle pressure chamber is formed by the IPMC combined muscle power component, a backflow channel, water outlet holes and the like, the pressure chambers are connected through the one-way valves, the whole atrium pressure chambers and the whole ventricle pressure chambers are arrayed in the shape of six parallel circumferences, and water flows out of the water outlet holes through the one-way valves. The heart-imitating underwater propeller has the advantages of being low in noise, disturbance and energy consumption and the like when the propeller works underwater.

Problems solved by technology

The study found that the mechanical design structure and processing technology of traditional propeller rudder propulsion are complicated, and it shows large noise and disturbance during underwater operation. At the same time, the propulsion efficiency is low during underwater propulsion, and it is not suitable for small underwater propulsion equipment. hydraulic propulsion options

On the other hand, the propulsion methods of bionic underwater biological prototypes have gradually gained the recognition and attention of scholars. The bionic propulsion methods such as fluctuating and swinging fin propulsion, biological flagella propulsion and jet recoil propulsion conform to the evolution law of natural organisms and have high efficiency, but the research on bionic propulsion is limited to the problems of similarities and complex mechanical structures, and the results of the research cannot meet the needs of practical problems.
