Description

Technical Field

[0001] The utility model belongs to the technical field of optical cables and electric cables, and relates to a remote supply optical cable for underwater detectors. Background Art

[0002] The cables and optical cables used for underwater detectors, especially those used for deep-water detectors, operate at great depths, and the lateral pressure and tension on the cables are very large, so the cable structure and watertight materials need to be high-strength. If it is a deep-water detector, multiple insulated wires are required as power supply units, which increases the cable diameter and reduces the ability to withstand the lateral water pressure. Usually, two or more insulated wire cores containing conductors are twisted together with an optical unit. In addition, due to the large drop and large load, more reinforcements are required, so the internal gap of the cable needs to be filled with more sealing materials, which adds unnecessary diameter and weight. In particular, medium and large-sized detectors and underwater operation robots that move underwater often require greater remote power supply capabilities and tensile strength, which makes the optical-electric composite cables used large in diameter and heavy in weight.

[0003] Therefore, providing lightweight optical cables with solid structure, small cable diameter and convenient use, as well as relatively lightweight long-distance optical cables, has become a problem that the industry needs to solve. Summary of the invention

[0004] The utility model aims to provide a remote optical cable for underwater detectors, which solves the problems of stable structure, high lateral pressure resistance and high pulling force.

[0005] According to the technical solution provided by the utility model: a remote optical cable for underwater detectors includes an insulating layer, a plurality of optical units and a plurality of conductors are arranged in the insulating layer, an elastomer is filled in the insulating layer, and an aramid layer and an outer sheath are sequentially wrapped around the outer periphery of the insulating layer.

[0006] As a further improvement of the present invention, the optical unit includes a tight-buffered optical fiber.

[0007] As a further improvement of the utility model, the conductor is made of copper-clad steel wire or copper wire or steel wire.

[0008] As a further improvement of the utility model, the elastic body is made of rubber or silicon rubber.

[0009] As a further improvement of the utility model, the insulating layer adopts fluorocarbon polymer or cross-linked polyolefin or polyolefin.

[0010] As a further improvement of the utility model, the aramid layer is spirally wrapped around the outer periphery of the insulating layer.

[0011] As a further improvement of the utility model, the sheath is made of polyurethane or polyolefin sheath material.

[0012] As a further improvement of the utility model, a plurality of longitudinal arc-shaped convex strips are evenly distributed on the surface of the sheath.

[0013] As a further improvement of the utility model, there are several color-coded lines of different colors in the longitudinal arc-shaped convex strips on the surface of the sheath.

[0014] The positive effects of this application are:

[0015] The utility model discloses a remote power supply optical cable for underwater detectors, which has a compact structure and a tightly wrapped optical fiber placed in the structural gap of the conductor. On the one hand, it can provide remote power to the detector, and on the other hand, it can utilize the stress on the optical fiber detection cable to transmit detection signals and collect data in real time.

[0016] The utility model adopts a solid elastic body of rubber or silicone rubber after natural fluidization and cross-linking, which can reduce the deformation of the cable when it is subjected to side pressure, thereby protecting the optical fiber, and has good watertight performance.

The utility model has the advantages of stable structure and reliable performance, small cable diameter, high lateral compression strength, high tension, low overall cost, easy use, suitable for industrial promotion and application, and has high industrial utilization value.
