Self -propelled submarine pipeline buries device underground

The utility model provides a self -propelled submarine pipeline buries device underground, the device includes: crawler attachment, centering mechanism, spout and break through native mechanism, body mechanism and high pressure and make a class mechanism, wherein: crawler attachment sets up in the left and right sides of body mechanism below, and centering mechanism perpendicular and set up in the front end of body mechanism centrally with body mechanism, spout and break through the below of native establishment of institution in body mechanism, the mechanism holds the pipeline tightly through the centering, spouts to break through native mechanism and break ground under crawler attachment's drive, and the cooperation crawler attachment of centering mechanism constantly adjusts, realizes that independently the walking is trailed to the pipeline, the utility model discloses a tight location is pressed from both sides to the pipeline in centering mechanism, can follow the tracks of the pipeline in real time, realizes that the self -propelled sounding follows the line, through the water route switch unit, the segmentation of carrying out the water route is switched over, realizes in the ditch of seabed not that segmentation in the co -altitude is concentrated to break ground, improves the efficiency of ditching under the condition of the water route of limited flow and lift.
