Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure: 1-optical fiber, 2-stainless steel loose tube, 3-fiber paste, 4-steel wire reinforcement and 5-outer sheath.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the optical cable applicable to a wide area provided by the present invention includes an optical unit, two steel wire reinforcements 4, and an outer sheath 5, where the optical unit is composed of a plurality of optical fibers 1, a fiber paste 3, and a stainless steel loose tube 2, the two steel wire reinforcements 4 are arranged in parallel on two sides of the optical unit, and the outer sheath 5 wraps the optical unit and the outer sides of the two steel wire reinforcements 4.
As a further preferred embodiment of the present invention, in the present invention, a plurality of optical fibers 1 are sleeved inside a stainless steel loose tube 2, and the stainless steel loose tube 2 is filled with a fiber paste 3. Wherein the stainless steel loose tube is formed by welding 314 stainless steel bands through the curling deformation of laser welding equipment, and the thickness of the 314 stainless steel bands is preferably selected to be 0.2 mm.
As a further preferred embodiment of the present invention, the steel wire reinforcement 4 of the present invention is a galvanized steel wire having a diameter of 0.6 to 1.2mm
As a further preferred embodiment of the present invention, the outer sheath 5 of the present invention is formed by molding a PE sheath material.
The preparation process of the present invention is further illustrated below:
according to the production process requirement, optical fibers and coiled 314 stainless steel bands with different colors in proper quantity are respectively installed on an optical fiber pay-off rack and a stainless steel band pay-off rack at one end of a laser welding production line, the laser welding production line is started, the optical fiber pay-off rack and the stainless steel band pay-off rack execute an automatic wire-defense function, the stainless steel bands are curled and deformed into stainless steel tubes through a deformation processing device carried by the laser welding production line, meanwhile, fiber paste is injected into the stainless steel tubes, the optical fibers penetrate through the stainless steel tubes, the laser welding production line executes an online welding function, and therefore a stainless steel loose sleeve structure of an optical unit is formed. And the other end of the laser welding production line is used for accommodating the processed and molded optical unit into a special disc tool through an automatic take-up stand.
And moving the processed optical unit to a sheath process, and mounting the optical unit on a pay-off stand of a sheath production line. And the two steel wire pay-off racks which are arranged in front of the pay-off racks and close to the position of the sheath production line host are respectively provided with a coiled steel wire (namely a steel wire reinforcing piece). Sufficient PE sheath materials are added into a hopper of a sheath production line host, relevant parameters are set through a host control panel, the sheath production line host is started, an automatic paying-off function is realized by a paying-off rack and a steel wire paying-off rack, an optical unit wraps extruded sheath materials on the outer sides of the optical unit and the steel wire reinforcing piece under the limiting action of a sheath die through a sheath line host machine head under the action of traction force of a steel wire reinforcing piece, and therefore the outer sheath is formed. And after the outer sheath which is just extruded and molded is cooled by a water tank under the action of traction force, winding the processed optical cable on a special disc tool through an automatic take-up stand at the other end of the sheath production line. Thus, the optical cable is completed.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
