Embodiment Construction

[0012] The invention provides a method for long-distance optical fiber penetration into capillary, comprising the following steps:

[0013] (1) After attaching the front end of the optical fiber to the magnetic point, insert it into the capillary;

[0014] (2) Bring the strong magnet close to the magnetic point, and then move the strong magnet forward to drive the optical fiber into the capillary.

[0015] In addition, before the step (1), it also includes: putting the optical fiber into a lubricating pool, so that the lubricating mesons are attached to the optical fiber. It can reduce the forward resistance of the optical fiber penetration process.

[0016] In addition, in the step (1), a smooth cap is provided at the entrance of the capillary to prevent the entrance of the capillary from being scratched and damaged.

[0017] Also provided is a device for long-distance optical fiber penetration into the capillary, from figure 1 It can be seen from the figure that this long...

Abstract

The invention discloses a method for long-distance optical fiber threading into a capillary tube, which has the advantages of convenient implementation, good protection performance and effect, low cost, simple structure, simple operation, high efficiency and energy saving. This method of long-distance optical fiber penetration into capillary includes steps: (1) insert the front end of the optical fiber into the capillary after attaching the magnetic point; (2) move the strong magnet close to the magnetic point, and then move the strong magnet forward to drive the optical fiber Introduce capillary. Also provided is a device for threading an optical fiber over a long distance into a capillary.

Description

technical field [0001] The invention belongs to the technical field of optical fiber protection, and in particular relates to a method for long-distance optical fiber penetrating capillary tubes and a device using the method. Background technique [0002] With the rapid development of science and technology, optical fiber technology has been widely used in many fields. However, the use of optical fiber over long distances is limited by the disadvantages of the fiber itself being easily damaged, making it difficult. [0003] Especially in the application fields of long-distance monitoring and detection of oil wells, coalbed methane wells, shale gas wells, marine structures, ships, and seabeds, optical fibers are widely used as monitoring and transmission tools for environments and working conditions. Optical fibers require strength and a certain degree of sealing. Protection, and to avoid collisions and scratches, so there is an urgent need for a long-distance optical fiber ...
