Abstract

The invention discloses an umbilical cable for ocean engineering equipment. The umbilical cable comprises a central air pipe, control cable cores, a first shielding coating layer, power cables and a second shielding coating layer, wherein the control cable cores are wound in a first groove in a peripheral surface of the central air pipe through screws, the first shielding coating layer is matched with the control cable cores exposed out of the peripheral surface of the central air pipe, the power cables are matched with a second groove spirally arranged in the peripheral surface of the first shielding coating layer, and the second shielding coating layer is matched with the power cables exposed out of the peripheral surface of the first shielding coating layer. In the structural design, the tensile strength, the compressive strength and the corrosion resistance of the cable can be effectively improved through spiral winding layer by layer.

Description

technical field [0001] The invention relates to the technical field of cables for marine engineering, in particular to an umbilical cable for marine engineering equipment. Background technique [0002] At present, the main functions of the umbilical cable are: 1. Provide power for the underwater working system, 2. Provide hydraulic channels for the underwater production control system, 3. Provide chemical agent pipelines for oil and gas field development, 4. Transmit control signals; When used in the ocean, in order to adapt to the ocean environment, the umbilical cable needs to be suitable for submarine projects such as submarine trenching, submarine salvage, submarine mining, submarine exploration, submarine robots, and large-scale submarine tourism projects. The umbilical cable used for marine engineering is generally a A high-tech comprehensive cable that integrates power transmission, digital signal transmission, video signal transmission, and gas and liquid transportat...
