Description

Filling strip structure of submarine cable

Technical Field

The utility model relates to a filling structure especially relates to a packing strip structure of submarine cable.

Background

With the development of ocean wind power and national economy, the demand on submarine cables is increased, and the requirements on the working reliability and environmental protection performance are increased.

The submarine cable with the optical cable at the seabed generally uses a molding filling strip, and the submarine cable without the optical cable can adopt a polypropylene reticular tearing rope. The existing filling strip for the submarine cable is mostly processed by a returned material twice, has unsmooth surface, single weight and low strength, wastes resources, increases the manufacturing cost and does not meet the requirements of national environment-friendly development strategy.

The conventional submarine cable filling strip usually contains more substances harmful to the environment, has a heavy weight and a large smell, so that the submarine cable filling strip is harmful to the environment, wastes resources and increases the submarine cable cost; and the surface of the filling strip is not smooth, so that the phenomena of non-roundness of cabling, damage of a wrapping tape, extrusion of an optical fiber unit and the like are easily caused during cabling, great difficulty is brought to production and manufacturing, meanwhile, a quality hidden trouble is caused to a product, and the long-term operation reliability of the product is reduced.

Disclosure of Invention

The utility model aims to solve the technical problem that a packing strip structure of submarine cable that light in weight, intensity are high, environmental protection and stability can be good is provided.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a filler strip structure of submarine cable, includes first inner frame, second inner frame and exoskeleton, first inner frame the inner with the inner of second inner frame connect, first inner frame the outer end with the one end fixed connection of exoskeleton, the outer end of second inner frame with the other end fixed connection of exoskeleton, the middle part of exoskeleton be provided with inside sunken arc connection skeleton that is used for placing the optical cable, first inner frame respectively with the exoskeleton the arc connect the skeleton between the interval be provided with many spinal branchs poles, second inner frame with the exoskeleton the arc connect the skeleton between the interval be provided with many spinal branchs poles.

The inner diameter of the first inner framework and the inner diameter of the second inner framework are respectively matched with the outer diameter of the cable core. Make first inner frame and second inner frame respectively with cable core laminating effectual.

The outer diameter of the outer framework is consistent with the integral outer diameter after cabling. The outer framework is attached to the outer package of the cable, so that the whole cable is smoother.

The inner diameter of the arc-shaped connecting framework is consistent with the outer diameter of the optical cable.

The first inner frame, the second inner frame, the outer frame, the arc connection frame and the support rod are all made of PE or PVC materials. The production by adopting PE or PVC materials is more environment-friendly.

The supporting rod is obliquely arranged. The filling strip has high strength and good stability.

Compared with the prior art, the utility model has the advantages that the utility model discloses a filling strip structure of a submarine cable, because the filling strip is enclosed by a first inner framework, a second inner framework, an outer framework, an arc-shaped connecting framework and a support rod, the filling strip is a hollow structure, and the filling strip structure has the advantages of light weight and material saving;

because the arc-shaped connecting framework which is sunken inwards and used for placing the optical cable is arranged in the middle of the outer framework, the optical cable is placed in the filling strip, the optical cable is placed outside the filling strip, the stability of the optical cable can be kept, and the operation and the installation are easy in the production process, so that the working time is shortened; the length of the optical cable is increased, so that the strength is improved, the gathering margin of the optical cable is increased, the optical cable is not easy to break, and the service life of the optical cable in the cable is prolonged;

because a plurality of support rods are arranged between the first inner framework and the outer framework and between the first inner framework and the arc-shaped connecting framework respectively at intervals, and a plurality of support rods are arranged between the second inner framework and the outer framework at intervals, the strength of the filling strip is improved, and the stability of the filling strip is improved;

and the PE or PVC material is adopted for extrusion molding, so that the environment is protected.
