Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
As Figure 1-4.
The pusher flexible bionic machine fish of much more a kind of combination, it is mainly made up of fish 1, fish body, fish tail 6 and various fin, and as shown in Figure 1, fish 1 is made up of fish body artificial-muscle 2, flexible back bone 3 and flexible shaft 14 with flexible electrode, as shown in Figure 2.Flexible shaft 14 and some annular frame shapes (the similar vehicle steering structure being connected with flexible shaft 14, as Fig. 2) flexible back bone 3 formed machine fish skeleton structure 13 of the present utility model, described fish body artificial-muscle 2 is symmetrically distributed in flexible back bone 3 both sides, is tensioning state and is arranged between adjacent two annular flexible skeletons 3.Described fish body artificial-muscle 2 is a kind of dielectric type electroactive polymers, has the advantages such as energy density is high, fast response time, nothing friction noiseless, is similar to biological muscles.The agonistic muscle antagonist driving principle of the motion mimics biology of machine fish health, after fish body artificial-muscle 2 energisings of one side, tensile stress reduces, the fish body artificial-muscle 2 of opposite side will shrink, drive flexible shaft 14 and machine fish health to produce the continuous bend of one degree of freedom both direction, coordinate with tail fin 5 and form the propelling of health/tail fin.The fish flute artificial-muscle 2 of machine fish both sides can independently be controlled, and the waveform, wave amplitude, the frequency that change machine fish health can be controlled propulsive force and turning moment, and control setup can be provided with in fish body.
Dorsal fin 4, tail fin 5, anal fin 7, abdomeinal fin 8, pectoral fin 9 form the fin of machine fish, they all imitate true fin profile, fin 4,5,7,8,9 all adopts bilateral to drive cantilever beam structure, comprise sheet flexible frame 16 and the fin artificial-muscle 17 with flexible electrode, as shown in Figure 3, on sheet flexible frame 16, be processed with through hole, some layers of fin artificial-muscle 17 are installed on to sheet flexible frame 16 both sides with tensioning state, and make flexible electrode region on fin artificial-muscle 17 and the through-hole alignment of sheet flexible frame 16.In the time not switching on, fin 4,5,7,8,9 is aspect.When tensile stress after fin artificial-muscle 17 energisings of a side reduces, the fin artificial-muscle 17 of opposite side shrinks, and fin 4,5,7,8,9 can produce wide-angle continuous bend, forms and swings.
Two pectoral fins 9 of machine fish are symmetrically arranged in health front part sides lower end position, radially arrange.In the time not switching on, pectoral fin 9 is in flat state, for the balance of machine fish.Pectoral fin 9 is connected with the turning cylinder 19 of angle-adjusting mechanism 15, as shown in Figure 4, turning cylinder 19 one end of angle-adjusting mechanism 15 are through a ring frame 13 of machine fish health front portion, the other end and same ring frame 13 are hinged, turning cylinder 19 is driven by a pair of artificial-muscle 20 by rotating disk 18, and when tensile stress after artificial-muscle 20 energisings of a side reduces, the artificial-muscle 20 of opposite side shrinks, drive rotating disk 18 and turning cylinder 19 to rotate, change the angle of attack of pectoral fin 9.In the time that health/tail fin advances, the angle of attack that changes pectoral fin 9 can be realized floating and the dive of machine fish.After the angle of attack of pectoral fin 9 changes, pectoral fin 9 swings the antagonistic force that can produce forward or backward, and the swing of pectoral fin 9 is rotated compound motion function and coordinated with other fin and can form centre fin/fin is advanced.Both sides pectoral fin 9 is independent to be controlled, and in the time that both sides pectoral fin 9 adopts the different angles of attack and different operating frequency and bending amplitude, can produce turning moment and turn for machine fish.
Two abdomeinal fins 8 of machine fish are arranged symmetrically in lower end, health belly both sides, radially arrange, can coordinate pectoral fin 9 to form and advance when abdomeinal fin 8 swings.The dorsal fin 4 of machine fish is arranged in health back, is positioned at the vertical plane of symmetry, can produce flexural oscillations, and anal fin 7 is arranged in health afterbody lower end, is positioned at the vertical plane of symmetry, can produce flexural oscillations.Dorsal fin 4 and anal fin 7 are connected between two or more adjacent ring frames 13.Tail fin 5 is connected with fish tail 6, is positioned at the vertical plane of symmetry.
On fish 1 top, antenna 10 is installed, for wireless telecommunications and GPS navigation.Both sides fish 1 are provided with camera 12, for obtaining the image in machine fish front.At fish 1 front end, distance measuring sensor 11 is installed, for monitoring fish front whether have obstacle and and obstacle between distance, distance measuring sensor 11 can be used ultrasonic transduter, laser sensor, infrared pickoff etc.
On ring frame 13, fish tail 6 and the fin 4,5,7,8,9 of the fish of machine fish 1, flexible back bone, luminescent fibre is installed, for the motion of visual observation machine fish, also can increases the sight of machine fish.
The utility model does not relate to partly all prior aries that maybe can adopt same as the prior art to be realized.
