A turntable-driven swirling device for spud shoe lifting on an offshore drilling platform

Abstract

The present invention provides a turntable-driven rotary jetting device for spud shoe lifting on an offshore drilling platform. There is a valve chamber, the upper end of the shell is provided with an interface pipe, the lumen of the interface pipe communicates with the valve chamber, the lower end of the valve chamber is connected with an end cover through threads, the center of the end cover is vertically opened with a through hole, and the middle of the valve chamber is set There is an annular piston, and a protruding ring is arranged in the middle hole of the annular piston. The valve stem and the rotary jet drive plate are composed of the valve core and the rotary spray drive plate. The valve core and the rotary spray drive plate are arranged at the upper and lower ends of the valve stem. There is a vortex spray hole horizontally, and the vortex spray hole is connected to the water inlet hole through the outlet pipe. The valve core rotates automatically during the spraying process, which increases the spraying area and improves the spraying effect, and can quickly remove the seabed sludge. The package adsorption of the spud can accelerates the lifting of the spud can and shortens the transfer period of the work area of ​​the oil platform.

Description

technical field [0001] The invention relates to the technical field of offshore oil drilling platforms, in particular to a turntable-driven swirling device for lifting boots of offshore drilling platforms. Background technique [0002] The direction of the water column sprayed out by the jetting head of the jetting device in the prior art is fixed, so the action range of the jetting sediment is distributed in a point line, and the jetting area is small, and it is impossible to quickly remove the adsorption of the seabed sediment on the outer surface of the spud can. Can not reach the best rapid spraying and boosting effect. Contents of the invention [0003] The technical task of the present invention is to solve the deficiencies of the prior art, and provide a turntable-driven swirling device for spud shoe lifting of an offshore drilling platform. [0004] The technical scheme of the present invention is realized in the following manner. The rotary spray flushing device ...
