Bottom mud long-distance conveying protection structure

The utility model relates to the technical field of long-distance bottom mud conveying, in particular to a long-distance bottom mud conveying protection structure. According to the technical scheme, the device comprises a bottom plate, a U-shaped plate is arranged above the bottom plate, a protection mechanism used for protecting the connecting position of a pipeline is arranged at the middle end of the surface of the bottom plate, fixing and limiting mechanisms used for fixing and limiting the pipeline are arranged on the two sides of the protection mechanism, and a dismounting mechanism used for dismounting the U-shaped plate and the bottom plate is arranged on the bottom plate and located below the U-shaped plate. The pipeline fixing device has the advantages that a pipeline can be conveniently clamped and fixed through the fixing and limiting mechanism, and the situation that the stability of the connecting position of the pipeline is affected due to the fact that the position of the pipeline deviates is
