The invention belongs to the filed of
subsea pipeline
recovery, in particular to a pipeline emergency
recovery device. The pipeline emergency
recovery device comprises a hydraulic
system, a lifting hook head, a toothed
propeller, a guide cone, a lifting hook, a counterweight arm, a lock catch, a pressing plate, an annular
rope, a floating ball, an O-shaped ring, a base and the like; one end of thehydraulic
system is connected with the lifting hook head through a pin shaft, the other end of the hydraulic
system is connected with the toothed
propeller through a pin shaft, and the
tail end of the toothed
propeller is connected with the guide cone; the front section of the pipeline emergency recovery device adopts a circular upper layer bracket and a circular lower layer bracket to form a rigid support, the middle section of the pipeline emergency recovery device adopts a V-shaped groove to form a flexible support, and the rear section of the pipeline emergency recovery device adopts a square upper layer bracket and a square lower layer bracket to form a rigid support. The pipeline emergency recovery device has the advantages that the recovery of an
underwater waste
subsea pipeline isachieved, the recovery device cooperates with an ROV
manipulator, a diver does not need to enter the water, thereby reducing the human capital and reducing the risks; the recovery device is utilizedto recover the
subsea pipeline, thereby being capable of reducing the
underwater operation time, and improving the construction speed and operation efficiency; a locking and self-locking device is utilized, the structure is simple and convenient, and the operation stability is improved.
