Dischargeable passive optical cable pavement device special for underwater vehicle

Abstract

The invention provides a dischargeable passive optical cable pavement device special for an underwater vehicle, and belongs to the technical field of oceaneering. The dischargeable passive optical cable pavement device comprises a main body framework, a floatage material, an anti-collision beam, a drum supporting beam, a valve box support, a sacrificial anode, a cable pavement functional component and a hydraulic control device; the optical cable pavement device is overlapped on the underwater vehicle; and the dischargeable passive cable pavement functional component controlled by the hydraulic control device is adopted to finish short-distance and high-precision underwater optical cable seabed pavement work. After the optical cable pavement task is finished, the cable pavement functionalcomponent is discharged to the seabed instead of being recycled, so that the underwater vehicle finishes connection between the optical cable and a target node. The dischargeable passive optical cable pavement device has a simple structure and is efficient; as a tension control device is arranged in the cable pavement functional component, the tension of the optical cable can be adjusted effectively; and due to adoption of the hydraulic control device and rational utilization of a hydraulic power system adopted by the modern underwater vehicle, the dischargeable passive optical cable pavementdevice special for the underwater vehicle is more economic and secure than an underwater motor.

Description

technical field [0001] The invention relates to a special optical cable laying device for underwater vehicles, in particular to a detachable passive optical cable laying device for underwater vehicles for short-distance, high-precision underwater optical cable laying tasks, It belongs to the field of marine engineering technology. Background technique [0002] At present, the laying of underwater optical cables is mainly completed by submarine cable laying operation vessels, towed submarine cable burying systems and other equipment. For long-distance underwater optical cable laying, the accuracy requirements are not high. However, when it is applied to the task of laying short-distance and high-precision optical cables on the seabed, the use of large-scale equipment such as laying ships or submarine cable burying systems is inefficient. For underwater short-distance, high-precision optical cable deployment, it is necessary to use underwater special detection and operation e...

AI Technical Summary

Problems solved by technology

A cable guide pulley is installed at the front end of the cable drum to assist cable laying, but there is no submarine cable tension control device, and the cable tension cannot be adjusted

The cable routing of the cable routing chassis can be precisely controlled by manipulating the movement of the underwater vehicle, but it is bulky, complicated to process and assemble, and the cost of the underwater motor is high
