Submarine optical cable burying and crossing equipment

Abstract

The invention relates to the field of submarine optical cable laying, in particular to submarine optical cable burying and crossing equipment which comprises a machine body, two footstands are symmetrically arranged on the two sides of the machine body respectively, a water passing pipe is connected between the two footstands on the same side, and an equipment foot is arranged on the side, away from the water passing pipe, of each footstand. An optical cable opening is formed in the upper portion of the front side of the machine body, a scanning head is installed in the machine body below the optical cable opening, two water inlets are symmetrically formed in the two sides of the optical cable opening in the machine body, and a high-pressure injection tail is arranged behind the machine body. After a sensor arranged in front of the equipment scans the terrain, data is transmitted to a mechanical arm below the sensor, supporting legs of an optical cable protection mechanism preset at the bottom of the equipment are positioned, and the optical cable protection mechanism is inserted into the ground after the supporting legs pass through a place where the protection mechanism needs to be inserted, so that the optical cable is clamped and protected and is prevented from being suspended or bent.

Description

Technical field [0001] The present invention belongs to the field of submarine cable laying, in particular to a submarine cable buried spanning equipment. Background [0002] Generally, the burial of submarine optical cables is through the equipment to bury the optical cables in the place to dig a gully, so that the optical cables are placed in the gully, in the process of burying the optical cables, the direction of the ship is the direction of equipment movement, but the seabed situation is complex, obstacles will affect the burial of optical cables, but there are the following problems: [0003] (1) When the optical cable is buried on the seabed, it is sometimes necessary to cross the complex terrain, if the terrain gap is too large or the gully occurs, the method of deep burial or increase of the optical cable is often used, but the small gully will be suspended, and the optical cable is vulnerable to impact and water cut when the cable is suspended, resulting in a decrease ...

AI Technical Summary

Problems solved by technology

[0003] ① When the optical cable is buried on the seabed, it sometimes needs to cross complex terrain. If the terrain drop is too large or the gully occurs, the method of deep burying or adding the optical cable is often used, but the small ravine will appear suspended, and the optical cable is vulnerable to impact and water flow when suspended Cutting results in reduced life;

[0004] ②Using the casing method to protect the optical cable, although it can play a certain protective role, but the tubular structure is limited by the shape and cannot well buffer the bending of the optical cable in the protection section;
