Abstract
The utility model discloses a shape memory alloy type flexible fin ray of bionic fish. The whole fin ray is formed by sequentially connecting a base rod, a connecting rod and a long swinging rod, wherein the connecting rod is made of an electric or magnetic shape memory alloy with a whole-process memory effect. The flexible fin ray designed by the utility model can swing vertically and periodically according to the own deformation characteristics of the shape memory alloy, the size of the bionic fish can be effectively reduced, the flexible fin ray has the advantages of low energy consumption and low noise, and the bionic fish swims for a long distance favorably.
Description
Technical field
The utility model relates to a kind of Biomimetic Fish, is specially a kind of flexible fin ray of marmem of Biomimetic Fish.
Background technology
Under water in propulsion system research, along with the continuous progress of science and technology, the high performance that fluctuation fin advances pattern to show more and more causes scientific research personnel's interest, therefore, in recent years imitative fish shape propelling unit researchist and engineer start to pay close attention to and set about research dependence such as hairtail, Mo Guiyu, ray the move about fish of pattern of flexible fin fluctuation propelling, and repeat the needs of studying for science, design various Biomimetic Fish driving with the bionical fin of fin undulatory motion.
But at present, the bionical fin of existing Biomimetic Fish generally forms with the soft thin wing that is connected each fin ray by swinging fin ray, the bionical ray of one as described in patent CN201220086410.9, in use, forms the fluctuation shape motion of thin wing by swinging up and down of fin ray.In above mechanism, the swing of fin ray all adopts motor to drive, and not only causes Biomimetic Fish huge structure, and the noise while simultaneously work is large, and energy consumption is high, is unfavorable for moving about at a distance for a long time, can destroy the daily life environment of aquatic organism simultaneously.
Utility model content
For the problems referred to above, the utility model has designed a kind of flexible fin ray of marmem of Biomimetic Fish, it utilizes the distinctive deformation characteristic of marmem itself to realize the periodic wobble up and down of fin ray, can effectively reduce the volume of Biomimetic Fish, have that energy consumption is low, noise is little, be conducive to moving about at a distance of Biomimetic Fish.
For achieving the above object, the utility model is by the following technical solutions:
The flexible fin ray of the marmem of Biomimetic Fish, is characterized in that: whole fin ray is sequentially formed by connecting by base bar, pipe link and long fork, and wherein pipe link adopts the electricity of omnidistance memory effect to cause or magnetic shape memory alloy is made.
Further, the top of above-mentioned base bar is provided with one " U " type link slot, and the afterbody of described pipe link extend in this link slot and by screw and is connected.
Further, between above-mentioned pipe link afterbody and the bottom of link slot, being provided with one can be pipe link distortion the elastomeric pad of certain elastic space is provided.
Further, the afterbody of above-mentioned long fork is provided with one " U " type engagement groove, and the head of described pipe link extend in this engagement groove and by screw and is connected.
Further, between above-mentioned pipe link head and the bottom of engagement groove, being provided with one can be pipe link distortion the elastomeric pad of certain elastic space is provided.
Further, above-mentioned base bar and long fork are made up of PP material.
Pipe link in the utility model fin ray is caused by the electricity of omnidistance memory effect or magnetic shape memory alloy is made, and the marmem of omnidistance memory effect has following characteristic, time recover high-temperature-phase shape in heating, when cooling, become the identical and low-temperature phase shape of opposite orientation of shape.
In use, in the time that the mode by certain heats to marmem pipe link or be cooling, pipe link will occur bending and deformation or reversal deformation, thereby drives the long fork of long section synchronously to swing together, and the reciprocally swinging of realizing bionical fin moves.
The bionical fin of the utility model is compared existing structure, omit motor-driven structure, structure is light and handy, be conducive to micro-miniaturisation, can effectively reduce the volume of Biomimetic Fish, it is high that while marmem has power to weight ratio, noise-free feature, be conducive to moving about at a distance of Biomimetic Fish, and can not destroy the daily life environment of aquatic organism.

Detailed description of the invention
As illustrated in fig. 1 and 2, a kind of flexible fin ray of marmem of Biomimetic Fish, whole fin ray is sequentially formed by connecting by base bar 1, pipe link 2 and long fork 3, and wherein base bar 1 and long fork 3 are made up of PP material, and pipe link 2 adopts the electricity of omnidistance memory effect to cause or magnetic shape memory alloy is made.
The top of described base bar 1 is provided with one " U " type link slot 11, and the afterbody of described pipe link 2 extend in this link slot 11 and by the screw 4 of Triangle-Profile and is connected.Be provided with one " U " type engagement groove 31 with the afterbody of duration fork 3, the head of described pipe link 2 extend in this engagement groove 31 and by the screw 4 of Triangle-Profile and is connected.
At this, for moving axially of restriction marmem pipe link 2, simultaneously also for shape memory alloy deformation provides certain elastic space, described stating between pipe link 2 afterbodys and the bottom of link slot 11 is provided with an elastomeric pad 5, is also provided with the elastomeric pad 6 of certain elastic space between described pipe link 2 heads and the bottom of engagement groove 31.
Pipe link 2 in the utility model fin ray is caused by the electricity of omnidistance memory effect or magnetic shape memory alloy is made, and the marmem of omnidistance memory effect has following characteristic, time recover high-temperature-phase shape in heating, when cooling, become the identical and low-temperature phase shape of opposite orientation of shape.
In use, in the time that the mode by certain heats to marmem pipe link 2 or be cooling, pipe link 2 will occur bending and deformation or reversal deformation, and its structure as shown in Figures 3 and 4, thereby drive the long fork 3 of long section synchronously to swing together, realize the reciprocally swinging action of bionical fin.
The bionical fin of the utility model is compared existing structure, omit motor-driven structure, structure is light and handy, be conducive to micro-miniaturisation, can effectively reduce the volume of Biomimetic Fish, it is high that while marmem has power to weight ratio, noise-free feature, be conducive to moving about at a distance of Biomimetic Fish, and can not destroy the daily life environment of aquatic organism.
