Leaking stoppage pipe clamp device and locking device for leaking stoppage pipe clamp

Abstract

The invention relates to a leaking stoppage pipe clamp device and a locking device for a leaking stoppage pipe clamp. The locking device comprises at least one locking unit. The locking units are arranged on an opening in one side or openings in two opposite sides of the leaking stoppage pipe clamp. Each locking unit comprises a first locking module and a second locking module which are arranged in a spaced manner and can move in the opposite direction. Each first locking module comprises a first clamping groove. Each second locking module comprises a second clamping groove. Each second clamping groove and the corresponding first clamping groove cooperate mutually to be arranged on the leaking stoppage pipe clamp in a clamped manner. A first locking and connecting part arranged in a wedgeshape is arranged on at least one side wall, arranged in the moving direction, of each first clamping groove. A second locking and connecting part arranged in a wedge shape and arranged in the direction opposite to the corresponding first locking and connecting part is arranged on at least one side wall, arranged in the moving direction, of each second clamping groove. The first locking and connecting parts and the second locking and connecting parts cooperate with the leaking stoppage pipe clamp for locking. The locking device has the advantages of being high in automation degree, simple in structure, easy to operate, high in installing efficiency and high in success possibility.

Description

technical field [0001] The invention relates to the maintenance technology of sea pipes, more specifically, to a leak-stopping pipe clamping device and a locking device for leak-stopping pipe clamping. Background technique [0002] In recent years, the number of deep-water marine pipelines has been increasing. Due to the long-term design and construction of marine pipelines, marine environment, pipeline corrosion, and changeable media, accidents of deep-water marine pipeline leakage have become more and more frequent. This sudden leakage of deep-water sea pipelines poses a huge threat to oil and gas field production and the marine environment. Once the sea pipeline is damaged, it will cause great losses to the operation of deepwater oil and gas fields. In order to reduce huge economic losses such as marine environmental pollution and crude oil production shutdown, it is particularly important to repair damaged pipelines safely, quickly and reliably. However, since the main...

Problems solved by technology

However, since the maintenance of deep water pipelines is difficult and the cost is several times higher than that of shallow water pipelines, research on corresponding emergency maintenance plans and development of supporting maintenance tools for the leakage of deep water pipelines are of great importance to ensure the safe production of oil and gas fields. important meaning

[0003] At present, the plugging pipe clips for sea pipes operated by divers within 300 meters and the plugging pipe clips for deep-water sea pipes operated by ROVs above 300 meters in China are all fixed by bolt locking. When installing by ROV in waters above 300 meters, due to the large number of them, ROV operation torque wrenches are required to install one by one. The underwater operation is very difficult and the efficiency is extremely low. Card test failure and other risks, the effect is very poor
