Description
Technical field
The present invention relates to a kind of pair to withhold seal plug core, is applied to Fibre Optical Sensor field of engineering technology.
Background technology
The piezoelectric type water primarily now used listens the stifled cored structure reliability in briny environment of sensor not high, as in light
The stifled cored structure used in fine sensory field needs for a long time in complicated briny environment, the leakproofness of structure, resistance to pressure and resistance to
Corrosivity is critically important consideration main points；Stifled core is mainly the stifled core of piezoelectric transducer at present, and sealing structure is inadequate；It is interior
Without any material water-proof material, water resistance is poor in portion；Outside is by seawater corrosion, unprotect measure, and reliability is not high；Dispensing is not square
Just, structural strength is inadequate, and service life falls short of；And a new generation fibre optic hydrophone needed in briny environment it is decade-long
Service life is the important component inside protection not by sea water intrusion and destruction, more next to the sealing structure demand of high reliability
It is more urgent.
Invention content
There is provided it is an object of the invention to overcome the deficiencies in the prior art and defect it is a kind of can be in complicated seawater ring
It is used in border, high double of good corrosion resistance, resistance to hydrostatic pressure, long lifespan, high reliability withhold seal plug core.
To achieve the goals above, the technical solution adopted in the present invention is：
It is a kind of double to withhold seal plug core, including stifled core ontology, the head end of the stifled core ontology between tail end along stifled core sheet
The circumferencial direction of body is provided with an annular groove, and the annular groove makes the stifled core ontology in an axial direction the two of annular groove
Side forms the sealing base of two protrusions, and the lateral surface of two sealing bases is equipped with incised groove, the stifled core sheet
Extracorporeal set has a PU pipes, withholds ring by corresponding with sealing base position on the outside of the PU pipes and is held on sealing base, detains
The pressure of pressure ring makes PU pipes be pressed on the sealed connection for realizing PU pipe and stifled core ontology in incised groove.
The PU pipes and the sealing base on stifled core ontology are tight fit.
Core body central line is blocked up in the sealing base medial surface upper edge by caudal part be arranged with two in the annular groove
Group through-hole, every group of through-hole are equipped with two through-holes symmetrical above and below, and the sealing base is equipped between every group of two through-holes
Semicircular fixed ring, the traction rope are mounted on by through-hole in fixed ring, and stifled core sheet is stretched out at the both ends of traction rope
Body.
Material water-proof material layer is filled in annular groove between two sealing bases.
The channel of setting main cable is equipped in the stifled core ontology, the outside of the stifled core ontology is equipped with two along channel direction
A dispensing hole is connected to channel.
By adopting the above scheme, double fastened structures that the present apparatus withholds ring compression using two form double containment, and
Withholding the part between ring two has filling material water-proof material, and water resistance and sealing performance are more preferable, and fastened structure is simple, can
By property height, semicircular fixed ring is set for fixed tractive in the annular groove of stifled core ontology by being arranged, fixation can
It leans on, prevents traction rope from deviating from a relaxed state.
In conclusion the present apparatus, which overcomes piezoelectric transducer, blocks up the defect that core ontology can not use in marine environment,
Also better seal, longer service life and higher reliability the advantages that.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
Fig. 2 is the sectional view of the present invention.
Specific implementation mode
Below in conjunction with the accompanying drawings, specific implementation of the patent mode is further described.
It is a kind of double to withhold seal plug core as shown in Fig. 1 to 2, including stifled core ontology 4, semicircular fixed ring 5, PU pipes 1,
The filled layer that blocks water withheld ring 2 and be made of material water-proof material；
The channel of setting main cable is equipped in the stifled core ontology, the outside of the stifled core ontology is equipped with two along channel direction
A dispensing hole is connected to channel.The naked fibre 7 for having shelled the main cable 10 of exterior cover sheets is passed through from the channel, in naked fibre 7 and master
A small sprue 9 is arranged in the junction of optical cable 10, naked in channel in order to ensure to which naked fibre 7 is sealed in the channel
Fibre 7 is not corroded by other external objects, ensures the leakproofness of the channel orifices, when in use the point in a dispensing hole
Glue, since channel interior is plugged, the gas and glue of stifled core inner can be discharged in another dispensing hole 8 at this time, make stifled core inner
Place naked fibre aperture filled by glue it is full, etc. reach one after glue curings and naked fibre sealed well and protective effect.
Stifled 4 outer diameter of core ontology is slightly larger than 1 internal diameter of PU pipes, ensures that PU pipes 1 can be held on the outer surface of stifled core ontology 4, detains
Pressure ring 2 applies it by forcing press pressure and generates the amount of withholding, and is allowed to be held on PU pipes 1, and ring 2 is being withheld on stifled core ontology 4
Position be provided with incised groove 41.
The value and stifled 4 outer surface of core ontology for withholding the amount of withholding of ring 2 are needed using 41 size of incised groove according to stifled core
Model is computed analysis and obtains, to ensure to block up the leakproofness of core ontology 4 and the anti-pull-out force abundance of stifled 4 connector of core ontology；
The present apparatus withhold ring 2 use two double fastened structures for withholding ring 2, two withhold ring 2 PU pipes 1 are pressed on it is stifled
On the incised groove 41 of core ontology 4 so that part PU pipes 1 are embedded in be formed to be close in incised groove 41 and connect, and block up core ontology
It is filled using material water-proof material layer in annular groove 3；
The present apparatus is managed as watertight connector and PU and the intermediate connection structure part of traction rope 6, and traction rope 6 passes through stifled core sheet
The through-hole 42 of 4 end face of body is pierced by around after semicircular fixed ring 5 from another through-hole 42, forms connection.To prevent traction rope
6 jump out from semicircle fixed ring inside groove in a relaxed state, increase the outer diameter of semicircle fixed ring 5.
