Description
Technical Field
The invention relates to the technical field of optical cable down-guiding, in particular to a guiding tube for optical cable down-guiding.
Background
The guiding optical cable is used as a connection part between the OPGW or the ADSS optical cable line side and the transformer substation communication machine room and is used for carrying the transmission of important information such as dispatching data network, relay protection and the like. The construction of the guiding optical cable sleeve in the transformer substation is a common fault point mainly because a unified, effective and standard waterproof blocking measure and a technological mode of the protective tube are not available at present. The current national network companies mostly adopt cement to plug, after the outdoor operation is carried out for several years, the blocking mud is often cracked and falls off after air drying, rain and insolation, so that the major operation hidden trouble of the guide optical cable is caused, and in order to effectively isolate and avoid rainwater, moisture, salt fog, dust, sundries, rodents and the like from entering the guide optical cable protection tube, the guide optical cable is caused to fail, thereby causing the power communication service to be not normally transmitted, and reasonable plugging methods and measures must be considered.
Thus, when the optical cable is guided into the machine room, it is connected to the machine room by means of the guide pipe in an "L" -shaped underground laying manner. A part of the guide pipe is buried in a backfill ditch under the ground, the overground part of the guide pipe is arranged on a transformer substation framework column, and one end bending part exists between the overground part and the underground part of the guide pipe. At present, the guide tube mainly adopts a steel tube, and when the steel tube is constructed, the steel tube is bent and extended to form a bending part through a process.

Detailed Description
The following description of the embodiments of the present invention will clearly and fully describe the technical aspects of the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, are intended to fall within the scope of the present invention.
As shown in fig. 1, the guiding tube for guiding down an optical cable of the present invention includes a tube body 1, a fixing assembly 2, a joint unit 3 and a sealing strip 4.
Wherein, the radial section of the first half pipe 11 and the radial section of the at least one second half pipe 12 enclose a radial section of the pipe body 1, and adjacent first half pipes 11 are matched with adjacent edges of the second half pipe 12 or two adjacent second half pipes 12 along the extending direction. In short, the pipe body 1 is formed by assembling the first half pipe 11 and at least one second half pipe 12 in a matched manner, and in actual construction, the first half pipe 11 and the second half pipe 12 are actually identical semicircular groove pipes. In addition, the edges of the first half pipe 11 and the second half pipe 12 are typically fastened by means of a snap fit or interference fit.
By adopting the technical scheme, when the optical cable is taken out from the steel pipe and the guide pipe is re-paved for reconstruction, the first half pipe 11 is put into the backfill ditch, the optical cable is put in the first half pipe 11 in a penetrating way, and the second half pipe 12 is buckled and spliced on the first half pipe 11, so that the optical cable is put in the new guide pipe in a penetrating way to realize the re-paving of the guide pipe; the transformation mode does not need to disconnect the optical cable to stop service in the construction process, so that transformation cost and transformation difficulty are greatly reduced.
Meanwhile, in order to facilitate subsequent maintenance and reduce maintenance cost, the technical scheme of the invention also adopts the following means.
The pipe body 1 further comprises pipe units 13, the pipe units 13 are sequentially arranged at intervals along the extending direction of the pipe body 1, each pipe unit 13 is formed by matching and enclosing a first half pipe 11 and at least one second half pipe 12, and the adjacent pipe units 13 are communicated with the joint unit 3.

By adopting the technical scheme, the pipe body 1 is formed by splicing a plurality of pipe units 13 in sequence, so that when damage occurs to one or more pipe units 13 of the guide pipe, maintenance can be completed by disconnecting the damaged pipe unit 13 from other adjacent pipe units 13 and replacing the new pipe unit 13.
It should be noted that, preferably, the pipe body 1 further includes a straight line section 14 and a curved section 15, the two straight line sections 14 are respectively disposed at two ends of the curved section 15 in the extending direction, a joint unit 3 is disposed between the straight line section 14 and the curved section 15, and the straight line section 14 includes at least two pipe units 13.
