Problems solved by technology

[0002] At present, the maintenance method of submarine pipelines is mainly to cut off the damaged pipelines, and then use pipeline connectors or underwater welding to connect the new pipelines to the cut pipelines. Because this method needs to cut the pipelines, the repair process is cumbersome and expensive. , Time-consuming, fast repair cannot be achieved in an emergency, and the possibility of failure is high, hindering the efficient and reliable repair of submarine pipelines

Abstract

The invention aims to provide a submarine pipeline clamp repairing connector comprising a first half-shell, a second half-shell, a first hydraulic cylinder and a second hydraulic cylinder. The first half-shell comprises a first gripping shell, a second gripping shell, a first compressing shell, a second compressing shell and a middle shell which are transversely arranged and connected in order; the middle shell is provided with a main radial seal groove and au auxiliary radial seal groove; the first gripping shell and the second gripping shell are provided with a first ball cage and a second ball cage, respectively; one side of the middle shell is provided with a connecting plate provided with a through hole. The first half-shell and the second half-shell are identical in structure; the first half-shell and the second half-shell are connected together through shell aligning pins inserted into through holes of respective connecting plates. The submarine pipeline clamp repairing connector allows a submarine pipeline to be quickly and reliably repaired without cutting it and is also suitable for connection of the submarine pipeline.

Description

technical field [0001] The invention relates to a submarine pipeline connection or repair device. Background technique [0002] At present, the maintenance method of submarine pipelines is mainly to cut off the damaged pipelines, and then use pipeline connectors or underwater welding to connect the new pipelines to the cut pipelines. Because this method needs to cut the pipelines, the repair process is cumbersome and expensive. , Time-consuming, fast repair cannot be achieved in an emergency, and the possibility of failure is high, which hinders efficient and reliable repair of submarine pipelines. Contents of the invention [0003] The object of the present invention is to provide a subsea pipeline clip repair connector that can quickly and reliably repair the subsea pipeline without cutting the pipeline, and can also be used for subsea pipeline connection. [0004] The purpose of the present invention is achieved like this: [0005] The seabed pipeline clamp repair con...
