Description
Technical field
This utility model relates to machine fish technical field, it particularly relates to a kind of simple joint bionic caudal fin.
Background technology
Marine organisms are at aspects, especially propulsive efficiency such as the mode advanced, motility, navigabilities even as high as
More than 98%, there is the existing artificial water surface or the incomparable superiority of underwater research vehicle.The tail fin of fish tail is put into being imitative fish machine
One recognized by device people various propelling pattern efficiently advances pattern, and this pattern can keep high in a phugoid mode of motion
The cruise performance of speed.Motor and specific transmission combination is used to drive, and more existing drive form (hydraulic pressure, motor, special
Material such as memorial alloy etc.), there is stronger driving force, big carrier can be driven, be suitable for that those speed bionical are fast, turn
The rapid marine organisms of body, have bigger researching value and application potential.
Utility model content
The purpose of this utility model is to provide a kind of simple joint bionic caudal fin, above-mentioned with overcome currently available technology to exist
Not enough.
For realizing above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of simple joint bionic caudal fin, including steering wheel, the steering wheel axle of described steering wheel is fixedly connected with actively spur gear, institute
The active spur gear engagement connection stated has driven spur gear, described driven spur gear to be fixedly connected on driven shaft.
Further, described driven spur gear is arranged in fish tail seat, and a part for described driven shaft is positioned at described
Fish tail seat in.
Further, it is tightly connected by O-ring seals between described driven shaft and fish tail seat.
Preferably, described driven spur gear is half gear.
Further, described steering wheel is fixedly installed on fish tail seat.
Further, also including steering wheel fixed mount, described steering wheel fixed mount is fixing with fish tail seat to be connected.
Further, described driving shaft is fixedly installed fish tail frame.
After using technique scheme, this utility model has following beneficial effect: this utility model tail fin swings and produces
Raw thrust forward, makes machine fish push ahead；It is provided with sealing ring between this utility model driven shaft and fish tail seat, can extend
The service life of tail fin；The advantage that this utility model has simple in construction.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
The accompanying drawing used required in is briefly described, it should be apparent that, the accompanying drawing in describing below is the most of the present utility model
Some embodiments, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to according to this
A little accompanying drawings obtain other accompanying drawing.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art are obtained, all belong to
Scope in this utility model protection.
As Figure 1-3, a kind of simple joint bionic caudal fin described in this utility model embodiment, including steering wheel 5, described rudder
Being fixedly connected with actively spur gear 6 on the steering wheel axle of machine 5, described active spur gear 6 engages connection driven spur gear 4, institute
The driven spur gear 4 stated is fixedly connected on driven shaft 2, and described driven spur gear 4 is arranged in fish tail seat 1, described from
A part for moving axis 2 is positioned at described fish tail seat 1, and described driven shaft 2 is fixedly installed fish tail frame 8.
When specifically used, described steering wheel 5 drives actively spur gear 6 to rotate by steering wheel axle, engages with active spur gear 6
Driven spur gear 4 concomitant rotation, driven shaft and driven spur gear synchronous axial system thus drive the swing of fish tail frame and tail fin.
In one embodiment, described driven spur gear 4 is half gear.Half gear-wheel gear-ring two ends are that tail fin swings
Two extreme positions, the design of half gear is possible to prevent tail fin to swing to overstep the extreme limit position and cause fault.
In one embodiment, it is tightly connected by O-ring seals between described driven shaft 2 and fish tail seat 1.Described
O-ring seals be possible to prevent water to flow in gear mechanism, extend the service life of bionic caudal fin.
In one embodiment, described steering wheel 5 is fixedly installed on fish tail seat 1.
In one embodiment, also including steering wheel fixed mount 7, described steering wheel fixed mount 7 is fixing with fish tail seat 1 even
Connect.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement etc. made, should be included in this utility model
Protection domain within.
