Description
Technical field
The utility model relates to optical technical field, is specifically related to a kind of optical fiber water-level gauge preventing condensing, is applicable to the level measuring in the large environment of the moist temperature difference.
Technical background
Water-level gauge (liquid level gauge) is a class sensor the most frequently used in moment sensor, and the degree of depth of height and various liquid level is equalled in the sea being mainly used in measuring water level, for modern intelligent management provides the most basic sensing basis.
But some special place is due to lightning protection, explosion-proof or there is the reasons such as strong electromagnetic, and sensing probe can not have live components, experiences carrier and must use safe energy, gives birth to because of fortune based on this kind of reason optical fiber (water-level gauge) liquid level gauge.Optical fiber (water-level gauge) liquid level gauge can not accomplish lightning protection, explosion-proof and electromagnetism interference etc. containing band electrical component due to probe segment.But the probe of optical fiber water-level gauge (liquid level gauge) is understood the sharply rising of Yin Wendu and produces condensation under special rugged environment.Condensation can cause the light scattering of fibre optical transmission thus cause reclaiming light leveling off to and zero causing optical fiber water-level gauge (liquid level gauge) to work.
Utility model content
The purpose of this utility model is the deficiency in order to overcome above-mentioned background technology, and provide a kind of optical fiber water-level gauge preventing condensing, structure is simple, easy for installation, optical fiber water-level gauge can be made to be applied in the large environment of the moist temperature difference, to improve optical fiber water-level gauge performance, expand water-level gauge applied environment.
A kind of optical fiber water-level gauge preventing condensing, comprise FC joint, described FC joint is arranged on one end of can, the can other end is provided with plano-convex lenses, plano-convex lenses side is plane, opposite side is convex surface, the plane of plano-convex lenses is coated with hydrophilic film and outside towards can, ceramic insertion core is provided with in FC joint, ceramic insertion core one end extend in can, the other end of ceramic insertion core and Fiber connection, be filled with optical fiber matching fluid in can, the optical axis of ceramic insertion core and the optical axis coincidence of plano-convex lenses.
The outer of the plane side of plano-convex lenses as above is provided with the annular edge edge that overall diameter is greater than the interior diameter of can, annular edge along and can between compress and be provided with sealing rubber ring.
The junction of FC joint as above and can is provided with fluid sealant.
The utility model is compared with the prior art, and has following beneficial effect:

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, but this embodiment should not be construed as restriction of the present utility model.
As shown in Figure 1, a kind of optical fiber water-level gauge preventing condensing, comprise FC joint 8, described FC joint 8 is arranged on one end of can 3, can 3 other end is provided with plano-convex lenses 4, plano-convex lenses 4 side is plane, opposite side is convex surface, the plane of plano-convex lenses 4 is coated with hydrophilic film 5 and outside towards can 3, ceramic insertion core 2 is provided with in FC joint 8, ceramic insertion core 2 one end extend in can 3, the other end of ceramic insertion core 2 is connected with optical fiber 1, optical fiber matching fluid 6 is filled with in can 3, the optical axis of ceramic insertion core 2 and the optical axis coincidence of plano-convex lenses 4.The outer of the plane side of plano-convex lenses 4 is provided with the annular edge edge that overall diameter is greater than the interior diameter of can 3, annular edge along and can 3 between compress and be provided with sealing rubber ring 7.FC joint 8 is provided with fluid sealant with the junction of can 3.
Optical fiber 1, ceramic insertion core 2 are connected by FC joint 8, FC joint 8 is fixed with can 3, can 3 can be tubular, guarantee that ceramic insertion core 2 is parallel with can 3 in can 3 center, use fluid sealant FC joint 8 and can 3 to be sealed and prevent optical fiber matching fluid 6 from revealing.In can 3, fill optical fiber matching fluid 6, optical fiber matching fluid 6 can reduce fiber end face light reflection strength and increase the inside and outside minute surface reduction condensation intensity that specific heat capacity makes plano-convex lenses 4 simultaneously.Hydrophilic film 5 is plating in the plane in plano-convex lenses 4, plano-convex lenses 4, sealing rubber ring 7 are assembled with can 3.Hydrophilic film 5 can make the globule condense into moisture film thus prevent camera lens from condensing.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
