A flushing and burying equipment for submarine cable laying

Abstract

The invention relates to the technical field of submarine cable laying equipment, and discloses a flushing and embedding equipment for laying submarine cables, which includes an upper bracket, a fixed bracket is fixedly installed on the top of the upper bracket, and both sides of the bottom end of the upper bracket are passed through pins. The side baffles are connected, and the upper bracket and the side baffles are connected through hydraulic piston transmission. The flushing and burying equipment used for submarine cable laying uses the high-pressure water flow generated by the fixed bracket to impact the sea mud through the setting of the side baffle and the sealing connecting plate, and at the same time, the side baffle blocks the flow of the sea mud, so that the sea mud can be Form a stable ditch, and use guide wheels and pre-embedded guide wheels to pull the cables laid on the surface of the seabed into the ditch, and automatically bury them under the flow of sea mud, eliminating the need to use dredger pumps to flush water and absorb more fluidity The sea mud is used to bury the cable, which effectively reduces the power consumption of the burial equipment, and at the same time improves the work efficiency of the cable burial protection.

Description

technical field [0001] The invention relates to the technical field of submarine cable laying equipment, in particular to a flushing and burying equipment used for laying submarine cables. Background technique [0002] Submarine cable is used as a power transmission and communication trunk line connecting cities, mainlands, islands, and even internationally. It is the most reliable, safe and effective means of telecommunication transmission at present. The laying of the entire submarine cable is difficult and dangerous, so the laying operation cannot be completed at one time. It needs to be divided into three stages: line survey and cleaning, cable laying, and burial protection. [0003] Among them, as the last link in the whole cable laying process, the burial protection is mainly to bury the cable 1 to 1.5 meters below the sea mud, so as to prevent the cable from being pulled on the seabed surface due to the flow of seawater or between the rocks. Scratch damage and other ...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a burial equipment for submarine cable laying, which has the advantages of low power consumption for the equipment and high burial efficiency of the cable, and solves the problem of using a dredge pump to flush and absorb sea mud, thereby forming The trench buries the cable to the specified depth. Due to the high fluidity of the sea mud and the seawater is always in a flowing state, the sea mud will be filled by other sea mud immediately after being extracted, which will consume a lot of power for the equipment and Most of the work done is useless, which leads to the low efficiency of the entire flushing and suction mud, and the problem of low work efficiency in cable burial protection
