Adaptive variable-area tail fin underwater propulsion device

Abstract

The invention relates to the technical field of biomimicry, in particular to an adaptive variable-area tail fin underwater propulsion device. The adaptive variable-area tail fin underwater propulsiondevice comprises a tail fin mounting plate, wherein first shape memory metal is embedded in the tail fin mounting plate, and the other end of the first shape memory metal is fixed to a supporting plate; and the tail fin mounting plate is further connected with a tail fin deformation part, the tail fin deformation part is in an isosceles triangle shape integrally, the tail fin deformation part is provided with waist rods and a bottom rod, and two tail end motion rod parts are connected to the middle part of the bottom rod. The supporting plate is connected to the bottom rod of the tail fin deformation part through two pull rods, one ends of the pull rods are fixed into tip connecting fixing holes of the supporting plate, and the other ends of the pull rods are fixed to the joints of the bottom rod of the tail fin deformation part and the end motion rod parts. According to the adaptive variable-area tail fin underwater propulsion device, various scientific research and production activities such as ocean exploration, ocean protection are facilitated for human beings in the future.

Description

technical field [0001] The invention relates to the technical field of bionics, in particular to an adaptive variable-area caudal fin underwater propulsion device. Background technique [0002] With the accelerated pace of human utilization and development of marine resources, human beings attach great importance to the fields of marine exploration and marine protection, and the research on bionic underwater propellers has gradually developed. There are also many problems in current underwater propulsion, such as heavy weight, single swimming form, high energy consumption, low efficiency, and poor mobility. Currently, the bionic robot fish is more popular as the underwater propeller. Fish achieve highly difficult and highly skilled movements through the coordinated movement of their fins and the swing of their tails. The role of the caudal fin is very important. In terms of propulsion mode, the swinging mode of the caudal fin is the mode with the highest efficiency and the...
