Abstract
The utility model discloses a direct-buried optical cable laying machine cable depth monitor which is formed by a fixation support body, a test rod and an alarm. The test rod passes through the fixation support body; the test rod stretches into an optical cable trench; the top end of the test rod is provided with a reset spring; the top portion of the reset spring is fixedly arranged under the fixation support body; the lower end of the test rod is equipped with an optical cable guide wheel which contacts with a direct-buried optical cable; the upper end of the test rod is equipped with a pad which is connected with the bottom of the reset spring, thereby enabling the test rod to be tightly contacted with an optical cable to be tested; and one trigger end of an alarm trigger switch is fixedly arranged on the fixation support body, and the other trigger end is fixedly arranged on the pad. The cable depth monitor not only can detect whether the cable depth reaches the standard, but also can send an alarm for reminding when the cable buried depth is not deep enough, thereby meeting the requirement for qualified whole-course optical cable buried depth, preventing reworking, saving a large quantity of manpower, and improving work efficiency.
Description
Technical field
When the utility model relates to a kind of instruction optical fiber cable for direct burial placing in machine operation, the device of monitoring optical cable buried depth situation up to standard.
Background technology
At Northern China Plains, the optical fiber cable for direct burial construction optical fiber cable for direct burial machines that adopt are implemented more, and this machinery is by optical fiber cable for direct burial ditching and lay optical cable two procedures and once merged, and operating efficiency is very high.Known at present, the dark measuring method of optical fiber cable for direct burial cable is to use tape measure, is measured piecemeal, records and checked on along direct-burried circuit by supervising engineer, adopts for the location that cannot directly measure the digging mode that breaks ground, and samples witness.This mode is feasible for the mode that lays again optical cable with artificial and excavator excavation optical cable ditch, but just produce problem for adopting optical fiber cable for direct burial machine to lay mode, because the furrow width of optical fiber cable for direct burial machine excavation is very narrow, while using tape measure, ditch depth reaches below one meter, ditch is interior just pitch-dark, cannot observe the state of tape measure, while usually causing measuring, can produce tape measure bending in ditch, or do not detect the phenomenon of bottom of trench at all, and cause producing measuring error, can say and cannot measure with tape measure; And adopt the digging mode that breaks ground, and needing to select a large amount of sampling spots, this need spend a large amount of manpowers, time and excavate, measures, and affects project progress; And can be large because of excavation face, cause land owner's claim, produce enormous expenditure, bring very large difficulty to the work of supervisor's scene evidence taking.
Summary of the invention
The purpose of this utility model is: overcomes existing measurement difficulty, provides a kind of cable dark monitor,
The utility model is made up of fixed support body, reference test bar and alarm, reference test bar of fixed support body inner passing-setting, reference test bar stretches in optical cable ditch, reference test bar top is provided with back-moving spring, fixed support body below is fixed at back-moving spring top, reference test bar lower end is equipped with optical cable guide wheel and contacts with optical fiber cable for direct burial, pad is installed in reference test bar upper end and back-moving spring bottom links, make reference test bar and tested optical cable close contact, one trigger end of alarm trigger switch is fixed in fixed support body, and another trigger end is fixed on pad.
Fixed support body described in the utility model is arranged on the reel stent car of optical fiber cable for direct burial placing in machine rear dragging.
Deeply whether the utility model can not only test out cable up to standard, and can in the time that optical cable buried depth is not enough, send to report to the police and give and point out, and reaches the qualified requirement of omnidistance optical cable buried depth, avoids doing over again, and has saved a large amount of manpowers, has improved work efficiency.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
The utility model is made up of fixed support body 1, reference test bar 3 and the alarm 5 of N shape fixed support.Fixed support body 1 is arranged on the reel stent car of optical fiber cable for direct burial placing in machine rear dragging, reference test bar 3 of fixed support body 1 inner passing-setting, reference test bar 3 stretches in optical cable ditch, it gos deep into partial-length and can adjust according to buried depth requirement, reference test bar 3 tops are provided with back-moving spring 2, fixed support body 1 below is fixed at back-moving spring 2 tops, reference test bar 3 lower ends are equipped with optical cable guide wheel 7 and contact with optical fiber cable for direct burial, play the effect of test optical fibre cables buried depth, reference test bar 3 upper ends are installed pad 6 and are linked with back-moving spring 2 bottoms, make reference test bar 3 and tested optical cable close contact, thereby measure the true buried depth of optical cable, one trigger end of alarm 5 trigger switches is fixed in fixed support body 1 by bolt 4, another trigger end is fixed on pad 6.In the time that optical cable buried depth is not enough, pad 6 separates with fixed support body 1, by trigger alarm, reaches monitoring optical cable degree of depth object whether up to standard.Make supervisor effectively supervise the buried depth of optical cable construction, increase work efficiency.
Claims (2)
