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.
