Abstract

A submarine cable burying device is capable of ditching the hard soil layer and burying a submarine cable under the combined action of tool bits and high pressure water jetting and has a high efficiency. The submarine cable burying device comprises a connection board on the upper portion, a supporting rod, a fairlead groove, a supporting seat, a hydraulic motor, a crank, a water jetting steel pipe and water jetting nozzles, wherein the supporting rod is connected with the left end of the connection board, the fairlead groove is arranged on the lower portion of the supporting rod, the supporting seat is arranged at the lower end of the connection board, the hydraulic motor is arranged at the right end of the connection board, the crank is arranged on an output shaft at the lower end of the hydraulic motor, the water jetting steel pipe is connected with an eccentric shaft of the crank through a connecting rod, and a plurality of the water jetting nozzles are arranged on the lower portion of the water jetting steel pipe. The burying device is provided with a plurality of the tool bits according to buried depth of the submarine cable, a tool shank is arranged on the upper portion of each of the tool bits, the upper portion of each tool shank is connected with a hinged support A through a pin shaft A in a pin joint mode, the middle of each tool shank is connected with a hinged support B through a pin shaft B in a pin joint mode, each pin shaft A is arranged on the lower portion of the supporting rod, and each pin shaft B is arranged on the lower portion of the water jetting steel pipe. The device is specially used for burying submarine cables.

Description

[0001] The invention relates to an embedding device, in particular to a submarine cable embedding device for embedding a submarine cable. 1. Background technology [0002] At present, most of the embedding devices used for laying submarine cables are hydraulic jet embedding devices, which just use high-pressure jets of water to punch out a groove in the seabed stratum, and then lay the submarine cable. High-pressure water jets are difficult and inefficient to penetrate through hard soil layers. 3. Contents of the invention [0003] The invention provides a submarine cable embedding device, which works together with a cutter head and a high-pressure water jet, and can dig trenches and embed submarine cables in a hard soil layer with high efficiency. [0004] The present invention is achieved through the following technical solutions: [0005] A submarine cable embedding device, comprising an upper connecting plate, a support rod connected to the left end of the conn...
