Abstract

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.

Description

technical field [0001] The invention belongs to the field of submarine pipeline recovery, and in particular relates to a pipeline emergency recovery device. Background technique [0002] Pipeline emergency recovery devices are widely used in the field of submarine pipeline recovery. At present, there is no self-developed recovery device in my country. The method of recovery of submarine pipelines mainly adopts the method of punching holes and pins. It is necessary to drill holes at appropriate positions from the cross section and insert high-strength pins. This method requires divers to work underwater, which consumes manpower; and it is easy to cause stress concentration to tear the sea pipe. This method is not suitable for large pipe piles and has low work efficiency and high cost. Contents of the invention [0003] The purpose of the present invention is to provide a pipeline emergency recovery device with simple principle and high efficiency. [0004] An emergency r...
