Abstract

The invention discloses a flexible zero-buoyancy photoelectric composite trailing cable, which comprises an optical unit arranged in the center, and an inner sheath layer, a power unit, a middle sheath layer, a flexible reinforcing unit and an outer sheath layer which are sequentially coated outside the optical unit, and the power unit is spirally twisted at the periphery of the inner sheath layerin the extending direction of the inner sheath layer by taking the inner sheath layer as an axis; the flexible reinforcing unit is made of non-metal yarns, the non-metal yarns are wound outside the middle sheath layer in a layered twisting mode, and the density of materials of the inner sheath layer, the middle sheath layer and the outer sheath layer is smaller than that of water, so that the specific gravity of the photoelectric composite trailing cable is balanced, and the density of the cable is approximate to that of seawater. The density of the cable is approximate to that of seawater through the comprehensive structural design, high-speed dragging of the whole water area depth can be achieved, and the requirement for repeated winding and unwinding can be met while the tensile strength of the whole cable is improved through the flexible reinforcing units.

Description

technical field [0001] The invention relates to the field of cable design and manufacture, in particular to a flexible zero-buoyancy photoelectric composite towing cable. Background technique [0002] In underwater detection work such as marine scientific research and defense, ships need to transmit power and signals to underwater working equipment, and at the same time, underwater signals are transmitted back to ships through optical fiber or electrical signal units. Part of the detection work requires high-speed towed equipment to patrol the sea area. Considering water resistance and equipment weight, the cable should have sufficient tensile strength. At the same time, the density of the cable should be similar to that of sea water, and it should be able to stay at the depth of the entire water area. The tow cable should be soft and durable. Grinding, it is convenient to return the equipment and instruments to the deck of the ship after work. [0003] The zero-buoyancy ca...
