Remote control submarine pipeline coupler

Abstract

The invention provides a remote-control submarine pipeline connecting device, which comprises a pipe connector, a support arranged on the pipe connector and a bottom plate arranged on the support, wherein a cylindrical piece is clamped between the pipe connector and the bottom plate; a sliding handle part of a sliding clamping jaw is arranged on a mobile hole on the support, while a sliding handle is connected with a connecting rod through a pin shaft; the other end of the connecting rod is connected with a supporting journal which is connected with a connecting block; a locating ring is sleeved outside the connecting block and is fixed on a sliding annular plate; and the sliding annular plate is connected with a double action piston of a hydraulic cylinder which is arranged on the pipe connector through a gland. The remote-control submarine pipeline connecting device can solve the automatic connection of deep-water submarine pipeline and has the advantages of accurate location and wide use range; the connecting device can be matched with the end shapes of various pipe fittings, and an adaptor and the sliding clamping jaw are matched with a shaft through an annular hole to improve stress status. Moreover, the connecting device provides the combined sealing form of a lens washer and an O-shaped ring so as to realize reliable sealing under deep water.

Description

(1) Technical field [0001] The invention relates to a pipeline coupling device, in particular to a remote-driven submarine pipeline coupling. (2) Background technology [0002] Jaw style pipe couplings are commonly used to provide remote actuated connections between pipes or other fittings. [0003] In U.S. Patent 4153278, the power is provided by a hydraulic cylinder, and the piston of the hydraulic cylinder drives the drive ring to move up and down, so that the jaws can rotate to realize opening and closing. When closing, one type is that the inner upper and lower parts of the jaws are partially spherical holes and matching pipe ends The spherical surface of the flange matches to realize the connection. Another type is that the upper taper hole on the inner side of the jaw matches the tapered surface of the matching pipe end flange, and the lower part of the spherical surface matches the spherical surface of the matching pipe end flange. There are problems of impact and i...
