A line patrol protecting device used for underwater pipeline tracking in the technical field of ocean engineering comprises a limiting mechanism, a force measuring mechanism and a pipeline position measuring mechanism. The limiting mechanism is connected with the force measuring mechanism and the pipeline position measuring mechanism. The limiting mechanism comprises a lifting mechanism, a left limiting unit and a right limiting unit. The left limiting unit and the right limiting unit are provided with driving mechanisms. One end of the lifting mechanism is connected with a ditcher. The other end of the lifting mechanism is connected with the left limiting unit and the right limiting unit. The driving mechanisms drive the corresponding left limiting unit and the corresponding right limiting unit to be opened and closed. Pipelines at different depths can be laid and buried through lifting control, pipeline centering efficiency is improved through pipeline position measurement, the pipelines can be effectively clamped and protected through pressure detection, and therefore pipeline deep burying efficiency is improved, and the construction period can be shortened.
Description
technical field [0001] The invention relates to a technique in the technical field of marine engineering, in particular to a line-observing protection device for underwater pipeline tracking. Background technique [0002] At present, the post-ditching method is generally used in the trench excavation of submarine pipelines. Its main form is that the trencher straddles the submarine pipeline and advances along the pipeline, and uses the trenching device on the trencher to dig out on the seabed below the pipeline. pipe ditch. In applications such as sea pipe detection, an important application method is that the submarine self-propelled submersible straddles the sea pipe and advances along the pipe, and uses the on-board detection equipment to detect the sea pipe. In these applications, a device is required to provide the following functions: 1) limit the trencher within a certain range of the submarine pipeline route; 2) measure the relative position between the pipeline and...
