Description

Submarine cable trench excavating device and system

Technical Field

Background

With the growing demand for global communications and power transmission, the laying of submarine cables is an important task in the field of marine engineering, which involves transporting submarine cables or pipes from one end to the other and placing them in place, a process that requires not only high precision positioning, but also the excavation of suitable trenches in the seabed in order to safely and stably embed the cables therein to protect the submarine cables. In the prior art, the excavation of submarine cable trenches mainly depends on two types of submarine plow-type trenchers and high-pressure jet-type trenchers.

The submarine plow-type ditcher cuts the submarine rock stratum into grooves by utilizing mechanical force under the dragging of a tugboat through a coulter, and is suitable for harder submarine strata; the high-pressure jet ditcher utilizes high-pressure water flow to flush the seabed so as to dig the grooves, is suitable for softer seabed strata, and can not effectively dig the grooves on the hard seabed or can take a long time to finish the digging task.

The traditional submarine cable slot excavating device adopts the cutting knife to excavate the submarine cable slot when the submarine cable is laid on the surface of the rock layer, adopts the high-pressure water gun to excavate the submarine cable slot when the surface of the soft covering layer, only has a single cutting mode or a single high-pressure water gun mode, and if the submarine cable excavating device needs to be replaced when the rock layer and the softer seabed are switched, if the submarine cable route is encountered, the submarine cable cannot be buried smoothly because the submarine cable route has two geology of the rock layer and the soft covering layer. Because the submarine environment has complexity and submarine geology has diversity, the submarine cable trench excavation device with a single function mode often has the problems of low efficiency, high cost and the like when the submarine cable trench is excavated.
