The capillary sealer for the fiber grating of the utility model can assure that the fiber grating can suits the axis perfectly in the capillary, can simplify the fiber grating capillary encapsulating process and has the advantages of simple structure, convenient operation, etc.
Description
(1), affiliated field
The utility model relates to a kind of processing unit (plant) of fiber grating.Specifically a kind of device that fiber grating is carried out encapsulation process.
(2), background technology
Fiber grating is a kind of sensing element of function admirable, no matter at technology maturity, or has all obtained the breakthrough of essence on the cost, applies it to the civil engineering work that has a large capacity and a wide range and becomes a reality.The major advantage that fiber grating is used for sensing is embodied in: be not subjected to the interference of electromagnetic field, electrical insulating property is good; Good endurance has opposing and comprises the various rugged surroundings of high temperature and the ability of chemical erosion; Light weight, volume be little, little to structure influence, be easy to arrange; Both point measurement can be realized, also distributed measurement can be realized; Absolute measurement; Save circuit, only just can the transfer structure status signal with single line; But signal, data multipath transmission are convenient to be connected with computing machine, and signal attenuation is little on the unit length; Highly sensitive, the precision height; Bandwidth, signal to noise ratio (S/N ratio) is high.But, because bare optical fibers and bare optical gratings is very thin especially, directly it can't be competent at extensive style construction of civil engineering work as sensor, as the lifting of concrete cast, steel construction etc., and abominable Service Environment.Therefore, bare optical fibers and bare optical gratings being carried out encapsulation process, is realization is applied fiber grating in field of civil engineering a necessary link.And fiber grating is encapsulated in the kapillary is the most frequently used method for packing.But also do not have at present a kind of the realization that fiber grating is encapsulated into isolated plant in the kapillary, the tubular type method for packing of having reported all is to adopt the method for direct injecting glue to carry out.Therefore fiber grating can not be well in kapillary and axis centering, and the sensing element of making has very strong randomness, has certain directivity during practical application, can't guarantee the stability and the actual demands of engineering of packaged fiber grating sensing characteristic.
(3), summary of the invention
The purpose of this utility model be to provide a kind of can guarantee fiber grating in kapillary well with axis centering, can simplify fiber grating capillary type packaging technology, simple in structure, easy to operate fiber grating capillary type packaging system.
The purpose of this utility model is achieved in that it comprises base, vertical support frame is installed on base, cross bar is installed on the vertical support frame, the end of cross bar is equipped with the kapillary geometrical clamp, the upper end of vertical support frame is provided with the adjustable metal sheet, have groove on the adjustable metal sheet, and be provided with the fastening rubber that matches with groove, it also comprises the vacuum extractor that is connected on the kapillary lower end.The utility model can also comprise some architectural features like this: 1, geometrical clamp is made of two steel discs and adjusting bolt, and steel disc is embedded with rubber blanket.2, have threaded hole on the vertical support frame, cross bar is installed on the vertical support frame by the adjusting screw(rod) that is installed in the threaded hole.3, base is made up of base plate and the supporting leg that is positioned under the base plate, in the middle of the negative through hole and installation sleeve is arranged, and has lock(ing) bolt on the installation sleeve, and vertical support frame is installed in the installation sleeve.4, described vacuum extractor is a suction pipe.
The utility model is a cover centering up and down, and the fiber grating tubular type packaging system that can arbitrarily dismantle.Kapillary vertically is fixed in the kapillary geometrical clamp, the grating that is connected with optical patchcord stretches into kapillary, and there is the part tail optical fiber to enter in the suction pipe that vacuumizes usefulness, make in the grating pair by the position of regulating adjustable metal sheet, kapillary geometrical clamp and cross bar, utilize the vacuum tube adsorption technology, will have certain mobile tackifier suction and arrange in the metal capillary of fiber grating.Device of the present utility model makes full use of the stressed uniform properties that vacuum tube is inhaled, fiber grating is encapsulated in the middle of metal capillary, after gelling is solid, fiber grating, tackifier, kapillary etc. constitute one, and expose one section tail optical fiber, so that welding temperature compensated optical fiber grating and cascaded fiber grating sensing element.Fiber grating occupy the centre of tackifier naturally under the hydrodynamic pressure of two lateral balances.That device of the present utility model has is simple in structure, detachable, good in the adjustable length, simple to operate, encapsulation grating pair, with batch encapsulation grating basically identical, tackifier be evenly distributed closely knit no bubble, advantage such as with low cost.Change vacuum extractor wherein into industrial controlled evacuator by suction pipe, just can satisfy the industrialized mass needs.Additional technical feature of the present utility model can be so that its adjustment be more flexible, accurate, and the scope of application is more extensive.
(4), description of drawings
Fig. 1 is the structural representation of apparatus of the present invention;
Fig. 2 is Fig. 1 vertical view (not being with base and adjustable metal sheet part).
(5), specific embodiments
For example the utility model is done more detailed description below in conjunction with accompanying drawing:
The composition of fiber grating capillary type packaging system comprises base.Base is made up of base plate 8 and the supporting leg 12 that is positioned under the base plate, in the middle of the negative through hole and installation sleeve 13 is arranged, and has lock(ing) bolt 7 on the installation sleeve.Vertical support frame 6 is installed on base, and vertical support frame is installed in the installation sleeve.Cross bar 14 is installed on the vertical support frame.The end of cross bar is equipped with kapillary geometrical clamp 1, and geometrical clamp is made of two steel discs and adjusting bolt 2, and steel disc is embedded with rubber blanket.The upper end of vertical support frame is provided with adjustable metal sheet 4, has groove on the adjustable metal sheet, and is provided with the fastening rubber 5 that matches with groove.Have threaded hole on the vertical support frame, cross bar is installed on the vertical support frame by the adjusting screw(rod) 3 that is installed in the threaded hole.Vacuum extractor in kapillary 9 lower ends.Vacuum extractor is a suction pipe 10, also can adopt evacuator.At first, kapillary vertically is fixed in the rubber blanket of capillary pipe clamp during use,, whether verifies around it good seal then with rapid solidification and by 502 glue of acetone solution suction pipe is fixed in a lower end capillaceous easily.To stretch into kapillary with the grating that wire jumper (or transmission cable) 11 is connected, guarantee that tail optical fiber has enough length and stretches into suction pipe, make in the grating pair by adjusting.Inject tackifier on kapillary top, slowly spur the suction pipe handle, tackifier can slowly flow into metal capillary under inner air and outer air pressure.Flow out tackifier if find downside capillaceous, illustrate that tackifier has been full of the capillary metal tube, at this moment open an aperture at the suction pipe wall, allow air enter, owing to the balance of air pressure up and down of capillary metal tube, tackifier has just rested in the capillary metal like this.With acetone suction pipe is taken off at last, treat that the tackifier natural coagulation promptly finished whole encapsulation process.
