A bionic underwater flapping wing propulsion device based on manta ray

Abstract

The invention discloses a bionic underwater flapping wing propelling device based on the manta ray. The device is composed of a servo motor, a reduction gear, a bracing wire wheel set, a fin ray mechanism, an outer framework and a skin. The fin ray mechanism is composed of multiple pressed rods and inhaul cables, the inhaul cables are connected with the bracing wire wheel set and the pressed rodsthrough V-shaped linear bearings, and therefore bracing wire wheels drive the pressed rods to move when rotating. The outer framework is installed on the vertical pressed rods of the fin ray mechanismand covered with the skin. The servo motor drives the bracing wire wheel set through a coupling and the reduction gear to rotate, the bracing wire wheel set pulls the fin ray mechanism to swing up and down, the outer framework on the fin ray mechanism and the skin covering the outer framework move and deform along with the swing of fin rays, and the flapping direction of flapping wings is controlled. The underwater flapping wing propelling device has the beneficial effects of being simple and reliable in structure, easy to control, capable of generating stable periodical propelling force, small in noise, high in stability and wide in application prospect.

Description

technical field [0001] The invention relates to an underwater propulsion device, in particular to a bionic underwater flapping wing propulsion device based on a manta ray; it belongs to the technical field of underwater vehicle propulsion. Background technique [0002] As a tool for exploring and developing the ocean, underwater vehicles play an important role in the process of human exploration of the ocean. In recent years, as humans have paid more and more attention to marine resources, underwater vehicles have played an increasingly important role. It is becoming more and more obvious and has broad application prospects. [0003] Traditional underwater vehicles mainly use the propeller propulsion method, which is limited by poor performance in low-speed environments, high noise, and poor maneuverability. Nowadays, people have higher and higher requirements for underwater vehicles to deal with complex situations in the ocean, and underwater vehicles need to have good man...
