Abstract
Disclosed is an underwater laying device for offshore oil and gas pipelines. By using a steel cuboid as the main body, a first mud-plowing rake, a first mud-plowing hoe, a second mud-plowing rake, a second mud-plowing hoe, and a mud delivery plate are disposed on the lower surface of the cuboid main body. Further, by cooperation of a mud collection hood and an elongated pipeline-delivery cylinder, and according to structural characteristics of traditional farming tools, submarine trenching, pipeline laying, and pipeline burying can be successively performed and all implemented by the device of the present invention. Further disclosed is a pipeline laying method of the device of the present invention. The device of the present invention has a simple structure, and overcomes the structural complexity of the conventional underwater robot on the premise of achieving the function requirements, thus greatly reducing the manufacturing cost and being mass-producible.
