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.

Example Embodiment

[0009] The drawing shows a specific embodiment of the present invention. The embodiment includes an upper connecting plate 16, a support rod 9 connected to the left end of the connecting plate, a fairlead 10 at the lower part of the support rod, and a support seat 4 at the lower end of the connecting plate. , The right end of the connecting plate is provided with a hydraulic motor 1, the lower output shaft of the hydraulic motor is provided with a crank 2, the water injection steel pipe 5 is connected with the eccentric shaft of the crank through the connecting rod 3, and the lower part of the water injection steel pipe 5 is provided with several water injection nozzles 8. There are a number of cutter heads 6 at the depth of the submarine cable. The upper part of each cutter head is equipped with a knife handle 7. The upper part of each knife handle is pin-connected to the reaming seat A14 through a pin A12, and the middle of each knife handle passes a pin shaft. B13 is pin-connected with hinge base B15, each hinge base A is arranged at the lower part of the support rod, and each hinge base B is arranged at the lower part of the water jet steel pipe.

[0010] When working, the embedding device is supported on the working mother ship through the support base 4, and the hydraulic motor drives the crank to rotate. The crank pushes and pulls the water jet steel pipe through the connecting rod during the rotation. Since the upper end of the knife handle is hinged to the support rod and the middle is hinged to the water jet steel pipe, the water jet When the steel pipe is moving up and down, the cutter head at the lower end of the knife handle also moves up and down to cut the seabed soil layer and ditch. The high-pressure water jet enters the water jet steel pipe from the water jet hose 11, and then is ejected from the water nozzle, and the knife head works together to quickly ditch. The submarine cable is guided into the trench from the fairlead and buried in the trench.

[0011] This equipment is specially used for laying of submarine cables.
