When the plastic optical fiber has broken fiber core, the broken section can be removed and the broken section can be maintained in a continuous mode due to the characteristic of easy connection, but the maintenance mode is difficult to realize due to the lack of the plastic optical fiber core breakpoint positioning detection equipment at present, and the plastic optical fiber with the breakpoint is always directly abandoned in actual work, so that serious resource waste is caused.
The invention comprises the following steps:
in view of this, it is necessary to design a detection device capable of locating the break point of the fiber core of the plastic optical fiber, so as to facilitate the location and maintenance of the break point of the fiber core of the faulty plastic optical fiber.
Plastic optical fiber breakpoint detection device includes: the device comprises a handle, a middle shaft, a track cam, a rotating wheel and a puncture needle assembly; the handle is fixedly connected with the track cam through a center shaft, and the rotating wheel is rotatably connected with the handle through the center shaft; the rotating wheel is a disc-shaped container, the outer surface of the outer edge of the rotating wheel is provided with a concave clamping groove, and a plurality of thorn pinholes are uniformly distributed on the outer edge wall; the needle assembly consists of a needle body, a needle tail and a needle optical fiber, wherein the front end of the needle body is provided with a cavity, the needle optical fiber is led out backwards from the cavity, the rear end of the needle body is connected with the needle tail, a needle tail connector is arranged on the needle tail and is connected with the track cam in a sliding fit manner, the needle body is installed in a needle hole in a sliding manner, the tail end of the needle optical fiber is connected with the side wall of the rotating wheel and penetrates out from the side wall of the rotating wheel, and a light sensing probe is arranged on the handle and positioned outside the tail end of the needle optical fiber.
When detecting a fault optical fiber, the optical fiber is clamped in a concave clamping groove, an optical signal is input at one end of the optical fiber, a hand-held handle dragging device slides along the optical fiber, the concave clamping groove is matched with the optical fiber to synchronously move, a rotating wheel rotates relative to a handle, in the process, a needle assembly rotates relative to a center shaft and reciprocates along a needle hole under the matching of a needle tail and a track cam, the optical fiber jacket is punctured, and the top of the needle optical fiber is contacted with an optical fiber cladding; when the equipment passes through the optical fiber damaged section, the damaged fiber core can leak light to the cladding, the pricker optical fiber contacting the optical fiber cladding can receive and transmit stronger optical signals, and the pricker optical fiber is received and alarmed by the optical sensing probe when the pricker optical fiber passes through the optical sensing probe, so that the damaged position of the optical fiber is determined, and the function of the equipment is realized.
Preferably, the outer edge wall of the rotating wheel protrudes inwards at the position of the puncture needle hole to form a puncture needle guide rail, so that the limiting stability of the puncture needle assembly is improved, and the puncture needle assembly is prevented from shaking and breaking.
The design also comprises an optical fiber limiting clamping wheel, wherein the optical fiber limiting clamping wheel is connected on the center shaft through a bracket, and the optical fiber limiting clamping wheel is positioned on the outer side of the concave clamping groove of the rotating wheel, so that the optical fiber is clamped between the optical fiber limiting clamping wheel and the concave clamping groove, and the optical fiber and the concave clamping groove are prevented from sliding relatively to damage the puncture needle assembly.
Preferably, the design further comprises a marking device, wherein the marking device is fixedly connected to the handle and is positioned at the outer side of the concave clamping groove of the rotating wheel, and when the photosensitive probe receives a detection light signal, the marking device automatically marks a corresponding optical fiber area, so that subsequent processing is facilitated.
