Description

Technical Field

[0001] The utility model relates to the technical field of cableway optical cables, in particular to an optical cable for a cableway with strong weather resistance. Background Art

[0002] Cableway is a kind of transportation, usually carrying passengers or goods up and down the rugged hillside. Optical cable is a necessary facility for cableway and plays a role in auxiliary communication. Currently, the common cableway optical cable is mainly a cylindrical cable with a built-in optical fiber core and an external insulating water-blocking layer, which is installed by erection. The above common types of cableway optical cables have the following shortcomings in actual applications:

[0003] Since the optical cable needs to be installed by laying, the middle part of the cable needs to be suspended in the air. The optical cable is bent in the air for a long time, and wrinkles and cracks are prone to appear at the center of gravity. In addition, the optical cable is exposed for a long time and is exposed to the sun and scratched by birds, so the service life of the optical cable is short. Utility Model Content

[0004] The utility model aims to provide a cableway optical cable with strong weather resistance, so as to solve the problem of short service life of the existing cableway optical cable proposed in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a weather-resistant optical cable for cableways, comprising a steel stranded cable, a plurality of evenly distributed load-bearing rings are sleeved on the steel stranded cable, a plurality of the load-bearing rings are fixedly provided with connecting pieces at their bottom ends, a main optical cable is fixedly provided between the plurality of connecting pieces, an outer sheath is fixedly provided on the outer side of the steel stranded cable, an arc-shaped cover is fixedly provided on both sides of the bottom of the outer sheath, the main optical cable is arranged at the bottom of the arc-shaped cover, the main optical cable comprises an outer sheath and a water-blocking inner sheath fixedly provided on the inner side of the outer sheath, an insulating filler is fixedly provided on the inner side of the water-blocking inner sheath, two optical fiber cores, two filling ropes and a non-metallic strengthening core are provided on the inner side of the insulating filler; the problem of long-term bending, wrinkling and cracking at the center of gravity of the suspended part of the optical cable can be reduced, the service life is long, and maintenance is convenient.

[0006] Preferably, the optical fiber core includes an optical fiber sleeve and a shielding layer fixedly arranged on the inner side of the optical fiber sleeve, a sleeve filler is fixedly arranged on the inner side of the shielding layer, and an optical core is fixedly arranged on the inner side of the sleeve filler; the communication is smooth and the anti-interference ability is strong.

[0007] Preferably, a plurality of evenly distributed aramid filaments are fixedly disposed inside the outer cladding, which can improve the bending and stretching resistance of the optical cable.

[0008] Preferably, the outer covering layer is made of polyethylene material, which is waterproof, corrosion-resistant and weather-resistant.

[0009] Preferably, the water-blocking inner sheath is water-blocking petroleum jelly, which is beneficial to improving the waterproofness of the optical cable.

[0010] Preferably, a plurality of evenly distributed reflective strips are fixedly provided on the outer side of the outer sheath, which can play a role of reflecting and driving away birds.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The cableway optical cable adopts a double-wire design, with a steel stranded cable on the top and the main optical cable on the bottom. The steel stranded cable is used for suspension installation to assist in bearing the weight and reduce the sagging and bending of the main optical cable, thereby reducing the problem of long-term bending, wrinkling and cracking at the center of gravity of the suspended part of the optical cable, and has a stronger load-bearing capacity.

[0013] Since there is a steel stranded cable above the optical cable, birds and other animals will not perch directly on the main optical cable, thus preventing them from pecking at the optical cable. Adding an arc cover on the outside of the main optical cable can reduce the probability of the main optical cable being exposed to the sun and rain, which is beneficial to increase the service life of the optical cable.
