Description
(1) technical field
What the present invention relates to is a kind of stripping assembly, particularly framework-taking optical fiber ring detaching device of optic fiber gyroscope.
(2) background technology
Technical field of optical fiber sensing usually runs into needs to use various different size optical fiber to carry out the work of the coiling of fiber optic loop, and the fiber optic loop of institute's coiling is also different according to the different desired technique for coiling of applied environment and use-pattern.Optical fibre gyro is a kind of important optical fiber angular-rate sensor, because its more distinctive advantage: volume is little, precision is high, dynamic range is big, no mechanical rotating part etc., more and more be subjected to the favor of each big colleges and universities and research institute, thereby just be widely used in various inertial navigation systems.Its transducing part is the fiber optic loop that is turned to by polarization maintaining optical fibre.This requires that the sensor fibre ring of coiling is had very high requirement.Traditional fiber optic loop all has skeleton structure, is subjected to the restriction around ring technology and encapsulation simultaneously, when changing in system environments (for example temperature) or the vibration of gyro own all can bring the distortion of fiber optic loop skeleton, thereby causes the variation of fiber stress.Certainly optical fiber itself also can produce STRESS VARIATION because of expanding with heat and contract with cold.The variation of these stress bring a nonreciprocal phase shift can for the modulation of gyro, is a potential source of the ghost effect relevant with transient phenomenon.The variation of stress can cause the variation of spread fiber constant and fiber size again, and this also can make receiver produce phase noise.The mode of traditional winding optical fiber ring all is above-mentioned used structures that skeleton is arranged, and will be subjected to the stress influence that above-mentioned various reasons produces eventually, and have to take the corresponding compensation technology, wastes time and energy, and effect is also undesirable.
At present, some reports about the optical fiber wind are also arranged.For example Chinese patent application number is 02136194, and name is called " optical fiber winding disc "; Application number is 200310118639, and name is called the disclosed technical schemes of patent document such as " spools that is used for twining optical fiber " etc.Though belong to same field with the present patent application, its goal of the invention and basic structure are all inequality.
(3) summary of the invention
The object of the present invention is to provide a kind of it can overcome traditional fiber around all stress influence of bringing owing to the existence of skeleton in the system scheme, the fiber optic loop of taking off skeleton that can coiling goes out different size, easy to use, framework-taking optical fiber ring detaching device of optic fiber gyroscope flexibly.
The object of the present invention is achieved like this:
Its composition comprises the disc of two same sizes, one group of fan page or leaf that can be combined into the same size of disk, have the location ladder on each fan page or leaf and the two sides all is evenly equipped with mounting hole, there is pilot hole the centre of disc, have on the surface of disc with the fan page or leaf on the corresponding mounting hole of mounting hole.
The present invention can also comprise:
1, described fan sheet is four and is 90 ° of fan pages or leaves.
2, the mounting hole on each fan sheet has three.
The present invention according to concrete operating position, selects the fan page or leaf of different model to be installed on the disc by adopting the fixedly disc of model, forms different radiuses, finishes the application under the different situations.Basic structure of the present invention is: the disc of two same sizes, and the fan page or leaf of four same sizes, each fan page or leaf is gone up uniform mounting hole and location ladder.Pilot hole and mounting hole are also arranged on the disc, and disc is annular, and four fan pages or leaves respectively are 90 °, can embed complete circle of the interior formation of ring groove of disc, simultaneously, four fan pages or leaves all can be fixed on two discs, thereby form a complete framework-taking optical fiber ring detaching device of optic fiber gyroscope.The radius of fan page or leaf can become according to the radius of the fiber optic loop that will twine, thereby just can turn to the fiber optic loop of different size, adapts to different applicable cases.The material of framework-taking optical fiber ring detaching device of optic fiber gyroscope uses duralumin, hard alumin ium alloy to make, and expansion coefficient is very little, and the deformation coefficient of the fiber optic loop stripping assembly of making is also less relatively, and the deformation that produces when extraneous temperature variation can be ignored.After the fiber optic loop coiling is finished, just can disassembled simply, back out the fixing screw of use, four fan pages or leaves can become flexible thereupon, thereby are diminished by four fans page complete radius of a circle of forming, and finally can take off the fiber optic loop that skeleton is successfully taken off in coiling easily.
The present invention can overcome traditional fiber around all stress influence of bringing owing to the existence of skeleton in the system scheme.According to different applicable cases, use the detachable disc and the fan page or leaf of different size, can coiling go out the fiber optic loop of taking off skeleton of different size, convenient, flexibly, various.
The applying flexible of framework-taking optical fiber ring detaching device of optic fiber gyroscope of the present invention is changeable, and environmental suitability is strong, is applicable to multiple optical fiber, can be applicable to various optical fiber technologies field.Each modular construction of framework-taking optical fiber ring detaching device of optic fiber gyroscope of the present invention is simple, is easy to processing, the yield rate height.Framework-taking optical fiber ring detaching device of optic fiber gyroscope simultaneously of the present invention uses duralumin, hard alumin ium alloy, and the deformation coefficient is little, the qualification rate height of the fiber optic loop of institute's coiling, efficient height.

(5) embodiment
For example the present invention is done description in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1 and Fig. 5, the composition of framework-taking optical fiber ring detaching device of optic fiber gyroscope comprises that 1,2, four of the discs of two same sizes can be combined into the fan page or leaf 3,4,5,6 of the same size of disk.In conjunction with Fig. 3 and Fig. 4, have location ladder 9 on each fan page or leaf and also all be evenly equipped with mounting hole 7 in the two sides simultaneously.In conjunction with Fig. 2 and Fig. 4, have on the surface of disc and the mounting hole 7 corresponding mounting holes of fanning on the page or leaf 8 simultaneously.Described fan sheet is four and is 90 ° of fan pages or leaves.Mounting hole on each fan sheet has three.
Optical fiber can carry out the coiling of fiber optic loop according to different technique for coiling and packaging technology on optical fiber coiling dish, after it solidifies gluing, framework-taking optical fiber ring detaching device of optic fiber gyroscope can simply be dismantled, back out the fixed screw on the disc, thereby the complete radius of a circle of being made up of four fan pages or leaves diminishes, finally can take off the fiber optic loop that skeleton is successfully taken off in coiling easily, go for different applicable cases.
Simultaneously, framework-taking optical fiber ring detaching device of optic fiber gyroscope can single-deck or polydisc stacked, thereby a plurality of fiber optic loop of coiling simultaneously reach and produce purpose efficiently.
