Description
Technical field
What the present invention relates to is a kind of travel switch, and particularly a kind of optical fiber position switch that is used to be operated under the high voltage environment belongs to sensor technical field.
Background technology
Along with the development of live line working, be used for the increasingly sophisticated and automation of implement under the high voltage environment, for example type super high voltage live cleaning robot of mentioning of patent 01126817.4 etc.The transducer of working in conventional environment is owing to directly connect the plant equipment that electric wire can not be used for the high voltage live line working.
Find by prior art documents, under the high voltage occasion, usually adopt special Fibre Optical Sensor, the fiber switch mentioned of patent 90212351.3 for example, the optical fiber code device of describing in the patent 92207264.7, and the MR121/312 ZapFree increment type spin fiber encoder of Micronor company release in the recent period etc.More than there are the following shortcoming in invention and product: structure is not suitable for stroke detection, and is not easy to be installed on the outside work equipment; Under the more occasion of dust, useful life is short, and is even not suitable; The using method complexity; Be not easy to dismounting; These transducers and optical fiber are connected to one more, and the frequent needs equipment of safeguarding of taking out stitches is used inconvenience.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of insulation is provided, anti-dust performance is good, cost is low, and it is close with line interface with conventional travel switch formal structure, be convenient to the optical fiber position switch dismantling and safeguard, it can be applicable in high voltage live line working, the high dust atmosphere condition.
The present invention is achieved by the following technical solutions, invention comprises roller, the top nail, upper cover plate, bracing frame, fiber adapter, optical fiber, optical-electrical converter, base plate, double-fiber collimator, mesochite and reflection part, its connected mode is: after bracing frame middle part is articulated in the top of upper cover plate by pin and leans on, its front portion is equipped with roller, the rear portion is near upper cover plate, upper cover plate by dowel fixes in mesochite upper end, base plate is adhered to the mesochite lower end, reflection part is fixed in the front side wall of mesochite inside, the top nail head is near the bracing frame bottom, and passing upper cover plate contacts with the reflection part top, double-fiber collimator is bonded in the V-type groove on the base plate, its head near and towards reflection part, fiber adapter by screw at the mesochite rear portion and pass mesochite, double-fiber collimator is connected in fiber adapter by optical fiber splice, and optical-electrical converter is positioned at a distance, is connected with fiber adapter by the optical fiber that has joint.
Reflection part according to the state of optical fiber position switch with the beam reflection in the launching fiber to receiving optical fiber, it comprises: reflective mirror, year runner plate, support spring, ballast plate, its connected mode is: reflective mirror is adhered to and carries runner plate, carry the chute that runner plate is arranged in the mesochite madial wall, the ballast plate is connected the chute both sides by screw, in chute, support spring is positioned at and carries a lower portion of mirror plate it is supported with the limit movement of carrying runner plate.Wherein reflective mirror places before the double-fiber collimator versatilely, and can be positioned at the reflection position of folded light beam and forbid the non-reflection position of folded light beam.
Pass placement dust ring in upper cover plate place for strengthening anti-dust performance at the top nail, pass upper cover plate after the top nail passes dust ring.
Also further in the outside mounting spring of top nail, this spring one end is near nail head lower end, top in the present invention, and the other end is close to dust ring, also can place rigid gasket between dust ring and spring.This spring makes dust ring be in pressured state all the time to have improved the dustproof effect, also makes the top nail head all the time near the bracing frame bottom simultaneously.
During this optical fiber position switch work, object is contact roller at first, cause bracing frame to rotate, promote to carry a runner plate by the top nail then reflective mirror is pushed into reflection position from non-reflection position, at this moment the light beam that is sent by the launching fiber of double-fiber collimator reflexes to reception optical fiber through reflective mirror.On the contrary, when object left, reflective mirror was reset to non-reflection position, and receive this moment does not have light signal in the optical fiber.The optical-electrical converter that is positioned at far-end is converted into the signal of telecommunication with light signal again.
The present invention compared with prior art has following advantage: dust prevention has been implemented in the inside and the outside of optical fiber position switch, in use can remain the good dust-proof performance.The formal structure that this invention is adopted is close with conventional travel switch, is applicable to the detection of position, and easy for installation, and the travel switch that can buy on available markets under the very little situation of demand is reequiped; Double-fiber collimator and optical fiber are movably connected on the fiber adapter that is fixed on the mesochite, have improved the flexibility of dismantling greatly though this mode has been introduced loss, are convenient to dismounting and maintenance.
