Description
Technical field
The present invention relates to a kind of underwater vehicle, and in particular to a kind of underwater vehicle load rejection mechanism.
Background technology
Underwater vehicle has important application value for navigational field, and measure etc. is many from resource exploration to water environment
Field has vital effect.And as the dive of submariner device and the load rejection mechanism of floating control process, in the work of submariner device
Have the function that irreplaceable during work, its reliability and security are to weigh the whether qualified most important finger of the mechanism
Mark.But current load rejection mechanism, based on the design of mechanical or fluid pressure type, structure is more complicated, and application process is dumb.
The content of the invention
The present invention is more complicated for the existing submariner device load rejection mechanism of solution, the inflexible problem of application process, and then provides
A kind of underwater vehicle load rejection mechanism.
It is of the invention to be for the technical scheme used that solves the above problems：
The underwater vehicle load rejection mechanism of the present invention includes relieving mechanism carrying platform, relieving mechanism inner sleeve, machine for releasing
Structure outer sleeve and weight carrying platform；
Weight carrying platform is arranged in the top of relieving mechanism carrying platform, the lower surface connection support of weight carrying platform
Frame, support frame and relieving mechanism carrying platform are rotatablely connected, the lower surface and relieving mechanism carrying platform of weight carrying platform it
Between be provided with the relieving mechanism inner sleeve and relieving mechanism outer sleeve being set in together, the upper surface of relieving mechanism outer sleeve with again
Thing carrying platform is connected, and the lower surface of relieving mechanism inner sleeve is connected with relieving mechanism carrying platform；
The overlapping region of relieving mechanism inner sleeve and relieving mechanism outer sleeve includes deformed region and non-deformed region, deformation
Region premade indentation, and impression number is more than or equal to 1；Relieving mechanism inner sleeve and relieving mechanism outer sleeve are remembered by shape
Recall polymeric material to be made.
The beneficial effects of the invention are as follows：The overlapping region that the present invention passes through relieving mechanism inner sleeve and relieving mechanism outer sleeve
Impression realize the locking process of the mechanism, impression is suppressed in the case of shape-memory polymer phase transformation, and in release,
Given to stimulate to make relieving mechanism inner sleeve and relieving mechanism outer sleeve close to phase transformation situation, then impression automatically replies, from
And axial displacement is produced between inside and outside sleeve, weight carrying platform tilts, and weight slides, it is achieved thereby that weight throws load process.
Because the load rejection mechanism of the present invention uses shape memory polymer material, its SME causes it locking
Had great application prospect on release tech, and there is presently no discharge underwater vehicle weight by such a method.
Intelligent load rejection mechanism of the present invention has simple in construction, and control is flexible, has very strong designability, for not
Same weight is using different depth and the impression of quantity so that the structure has very wide application, is someone and unmanned water
The design and manufacture of the load rejection mechanism of lower submariner device provide new idea and method.

It is to be obtained by mechanical indentation, and impression number is more than or equal to 1；Relieving mechanism inner sleeve 2 and relieving mechanism outer sleeve 3 are equal
It is made up of shape memory polymer material.
Deformed region premade indentation between the relieving mechanism inner sleeve 2 and relieving mechanism outer sleeve 3 of present embodiment, when
When needing to be discharged, using the SME of shape-memory material, make relieving mechanism inner sleeve 2 and relieving mechanism overcoat
Cylinder 3 returns back to original shape during no impression, then weight carrying platform 5 tilts, and weight 4, which is able to throw, carries release.
By certain stimulation (heat, electricity, light, magnetic, solution and ultrasound) sleeve have impression and without between impression turn
Change, realize the locking and release of mechanism, relieving mechanism inner sleeve 2 and the original shape of relieving mechanism outer sleeve 3 are the cylinder without impression
Shape, two carry out nesting, and phase transformation is brought it about after applying certain stimulate, and carry out impression in nested region, then realize mechanism
Locking, when disengagement is required, need to only give identical stimulation, then indented region automatically returns to original state, between two
Axial displacement can be produced, when the impression number of the relieving mechanism inner sleeve 2 and relieving mechanism outer sleeve 3 is multiple, was discharged
Journey can take one by one impression replied, can also take all impressions while reply.Support frame 7 is by connecting pin 6 with releasing
Laying mechanism carrying platform 1 is be hinged.
