Embodiment 1

[0023] see figure 1 As shown: the present invention is a mooring cable for a shipboard platform, and the mooring cable includes an optical signal transmission unit 1, a power transmission unit 2, a tensile strength member 3, a water-blocking yarn 4, a water-blocking tape 5 and an outer sheath6. The present invention not only adopts the design of the tensile reinforcement 3 to improve the tensile performance, but also adopts the design of the water-blocking yarn 4 and the water-blocking tape 5 to improve the waterproof performance.

[0024] The number of groups of the above-mentioned optical signal transmission units 1 is one group, and the group of optical signal transmission units 1 includes a bending-resistant optical fiber 101 and a high-temperature-resistant tight cladding 102 and a stainless steel tape spiral armor that are sequentially coated on the outside of the bending-resistant optical fiber 101 The sheath layer 103, the high temperature resistant tight cladding lay...

Embodiment 2

[0030] see figure 2 As shown: the other structure of this embodiment 2 is the same as that of embodiment 1, the difference is that: the mooring cable also includes a tapered roller bearing 9 and a connecting belt 10,

[0031] The power transmission units 7 are arranged parallel to each other along the length direction of the cable and evenly arranged around the optical signal transmission unit 11, which are respectively the first power transmission unit 701, the second power transmission unit 702, and the third power transmission unit 703. and a fourth power transmission unit 704 . Wherein, the power transmission unit 7 and the optical signal transmission unit 11 are also parallel to each other along the length direction of the cable.

[0032] There are multiple tapered roller bearings 9, which are evenly and spaced fixedly sleeved on the outer peripheral wall of the optical signal transmission unit 11 of the tethered cable. Tensile reinforcements 8 and water-blocking yarns...

Abstract

The invention discloses a mooring cable for a ship-borne platform. The mooring cable comprises an optical signal transmission unit, a power supply transmission unit, a tensile reinforcer, a water-blocking yarn, a water-blocking tape and an outer sheath. The group number of the optical signal transmission units is one. The group number of the power supply transmission units is an even number, and the number is at least four groups. The power supply transmission units are mutually and uniformly twisted around the optical signal transmission unit. The power transmission units are mutually and uniformly stranded around the optical signal transmission unit to form a stranded gap, the stranded gap is filled with a tensile reinforcer and a water-blocking yarn to form a cable core of the mooring cable, and the cable core of the mooring cable is sequentially wrapped by a water-blocking tape and an outer sheath. The mooring cable not only has good tensile performance, but also has good waterproof performance.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a mooring cable for a shipboard platform. Background technique [0002] Traditional ship-borne platforms use tethered cables as the connection channel between the ship-borne platform and aerial drones or underwater robots, carrying the key role of power supply and monitoring signal transmission. Specifically, it is mainly used in the transmission of power and monitoring signals between high-altitude tethered drones with a suspension height of about 100m or less or underwater robots with a suspension height of about 100m or less and a ship-borne platform. It has the characteristics of good maneuverability, convenient use, no risk of casualties, low cost, and good cost-effectiveness ratio. [0003] However, the traditional mooring cables for shipboard platforms generally have problems such as low tensile strength and poor watertightness, which seriously affect the safety of power t...
