Fig. 1 is the front view of the undulation propelling mechanism of shape-memory alloy wire driving; Fig. The present invention has following beneficial effect: the present invention utilizes the intellectual material shape-memory alloy wire as actuator, and the MPF in the imitation fish swimming pattern advances pattern, for bionic underwater robot provide a kind of flexibly, noise-free undulation propelling mechanism; Propulsive mechanism of the present invention is simple in structure, volume is little, and flexible movements are not subject to the influences of hydrophyte such as seabed pasture and water; Propulsive mechanism of the present invention can be combined into the fluctuation fin of any fluctuation fin divergence amount and length through modular design; Using the bionic underwater robot of this undulation propelling mechanism can advance in rock ditch seam, the more marine site of pasture and water; Carry out tasks such as observing, hide, be beneficial to and apply.
The objective of the invention is for solve adopting MPF to advance the undulatory propeller of mode motion to have complex structure, action noise is big and exercise performance is relatively poor problem, and then the undulation propelling mechanism that provides a kind of shape-memory alloy wire to drive. The material of the said first fin spoke 8 is plastics, metal, rubber or the thin bar of other better rigidity, and flexible covering can be connected on the fin spoke through direct stickup, mode such as penetrate.This undulation propelling mechanism can be positioned in the closure casing, only with fin spoke 8 and flexible covering 2 as for outside the housing.Can also as in liquid, working,, adopt heat-shrink tube or other wrapped with insulation in its outside, and carry out anticreep processing with whole propulsive mechanism as in the working medium in the joint for preventing memory alloy wire 7 electric leakages.

Shape-memory alloy wire 7-1 has one way shape-memory effect.Said shape-memory alloy wire does not limit material, as long as martensitic phase height Ms and Mf are higher than ambient temperature, and martensite reverse transformation temperature As and a little higher than ambient temperature of Af.The first shape-memory alloy wire 7-1 in this embodiment adopts the energising type of heating to drive.The pendulum angle that can control the fin spoke current”on”time easily through the control memory alloy wire. The present invention utilizes the memory effect of shape-memory alloy wire 7-1, and the contraction through memory alloy wire spurs first swinging block 9 and rotates around first rotating shaft 5, thereby drives fin spoke 8 swings that are connected on first swinging block 9.Shape-memory alloy wire in the first swing module 1 all is installed in the plane, and this mounting plane can have a certain degree with the end face of first support 4.This embodiment is simple in structure, flexible movements, reliable.
The said first fin spoke 8 of this embodiment is worked with differential mode; The first shape-memory alloy wire 7-1 is distributed in the two ends of first swinging block 9; One side, first shape-memory alloy wire 7-1 energising is shunk pulling first swinging block 9 and is rotated 8 swings of the drive first fin spoke, elongates the first shape-memory alloy wire 7-1 of opposition side simultaneously, during first shape-memory alloy wire 7-1 cooling; The first shape-memory alloy wire 7-1 energising of opposition side is shunk; Spur first swinging block 9 and rotate, drive the first fin spoke 8 to the opposition side swing, the first shape-memory alloy wire 7-1 of opposition side cooling then to opposition side.The crank motion of this differential type drives the periodic oscillations of fin spoke.
Existing employing MPF advances the undulatory propeller of mode motion mostly to adopt motor-driven, and propeller control is simple, and horsepower output is big, but motor has noise during motion, and complicated in mechanical structure.The undulatory propeller that adopts pneumatic mode to advance, controllability is good, but complex structure needs source of the gas.Employing current drives poly-mer (Electroactive Polymer, the undulatory propeller that EAP) drives is simple in structure, and quality is little, but the power output of EAP is less.The employing marmem (Shape Memory Alloy, SMA) undulatory propeller of thin plate driving carries out indirect heating through the resistor wire that is wrapped on the thin plate to SMA, and degradation of energy is big in the driving process, needs insulation between resistor wire and SMA thin plate. 1, and Fig. 4 is the vertical structure block diagram of swing module of the present invention; Fig. 6 is that shape-memory alloy wire is arranged and the connection scheme drawing in the vertical swing module, and Fig.
