Description
Technical field
The present invention relates to the static seal Wedge-type docking of a kind of butt joint locking mechanism, more particularly to a kind of subsea control modules
Retaining mechanism, belongs to Offshore Engineering field.
Background technology
About 34% is Marine oil and gas resource, 100,000,000,000 tons of left sides of Global Oil resource gross reserves in Global Oil total resources
The right side, and proven reserve is just 38,000,000,000 tons or so at present, and proven reserve nearly 80% is in deep water sea area.In the last few years, with
Being continuously increased for global energy requirement and jumping up for international oil price, promotes people constantly to expand global Oil Gas exploration
(E＆P) the gross investment scale of exploitation.According to related data statistics, from 2001 to 2005, offshore oil and gas E＆P was invested from about 690
Hundred million dollars rise to about 90,000,000,000 dollars, increase 1/3rd or so；Deep-sea oil gas E＆P capital investment shares account for global offshore oil and gas
E＆P invests the ratio of total share also in increase, and deep-sea oil gas E＆P investments rise to about 14,000,000,000 dollars, growth from about 9,200,000,000 dollars
1/2nd or so.According to statistics by 2010, global deep-sea oil gas E＆P investments reach about 20,000,000,000 dollars, increase compared with 2005
43%.As can be seen here, the exploitation of deep water hydrocarbon resource has been increasingly becoming the emphasis of Global Oil resource exploitation.
Subsea control modules (SCM) are each valves on the nucleus equipment of Subsea Control Systems, SCM control subsea production trees
Door, monitors the state of production tree, and feed back undersea device information, and water surface production platform and water to the equipment on sea in time
The co-ordination of lower production system is also to be realized by subsea control modules.Usual subsea control modules are and control waterborne
Module installs basal disc and is locked and be directly installed in controlled device, such as：Subsea production tree, subsea manifold
Deng.
At present, used existing retaining mechanism under water should in the structure type of dynamic sealing, supporting diving and deepwater environment more
With, but because its is complicated, and competence exertion goes out its sealing property to many dynamic sealings only when mechanism runs at high speed,
So being not suitable for being applied on subsea control modules.Because subsea control modules sealing position just meeting only in installation and dismounting
There is relative motion, therefore use static seal structure instead, static seal structure not only significantly reduces the machining accuracy and assembling essence of part
Degree demand, moreover, when static seal retaining mechanism works, encapsulant will not be worn, therefore static seal retaining mechanism is often
There is longer service life than movable sealing structure.
At present, existing underwater mating retaining mechanism has number of different types, and control locking is conciliate lock control principle majority and adopted
Worm drive mechanism is used, either dynamic sealing or static seal, its sealing structure is mainly all arranged on lock shaft, and docking is oriented to
Guide-localization is carried out more than mechanism using multiple alignment pins, and guide finger requires that the precision of processing and assembling is very high, often occurs
The stuck situation of docking.And use more and locked by rotation lock mandrel and lifting lock shaft using stuck mechanism retaining mechanism, this knot
The lock shaft of structure will not only be moved up and down, in addition it is also necessary to carry out spinning movement, require high to underwater robot (ROV) operation；And with
The increase of the depth of water, Underwater Pressure increasing and the reduction of visibility, docking and locking and ROV operations for retaining mechanism under water
Convenience propose higher requirement.
The content of the invention
The invention aims to more facilitate the installation and dismounting of underwater robot, and efficiently solve docking
Stuck the problem of, underwater mating locking is set to be more prone to operate and provide a kind of static seal wedge of compact conformation subsea control modules
Block formula butt joint locking mechanism.
The object of the present invention is achieved like this：Main body is docked including subsea control modules and on underwater installation
Pedestal, the center of the pedestal is provided with lower sleeve, and the inner surface setting of lower sleeve has to be set on locating ring, the pedestal
Have a hydraulic pressure public plug, subsea control modules docking main body include housing and the upper plate for being separately mounted to housing top and bottom and
Lower shoe, the upper plate upper end, which is provided with suspension ring body, suspension ring body, is provided with suspension ring, and ROV rotations are additionally provided with suspension ring body
Jack, the center of suspension ring body is provided with leading screw, and the center of upper plate, which is provided with end set, the leading screw, is provided with silk
Female and leading screw is stretched in the set of end, and support tube is provided between the upper plate and lower shoe, and the support tube and leading screw are same
Installation center pipe in axle, the support tube, the upper end of the central tube and screw are connected, lower end is fixed with mandrel, the bottom
The center of plate is provided with collar bush, and the end of collar bush is provided with, and the mandrel is stretched in collar bush, and the end of mandrel
Portion is fixed with cone and guide ring successively, and collar bush inner surface is respectively arranged with moveable locating piece and guide groove, the cone
The hydraulic pressure female plug for being additionally provided with and coordinating with hydraulic pressure public plug on the feather key coordinated with guide groove, the lower shoe is provided with body
Head, the leading screw is driven by the manipulator of underwater robot by ROV rotary jacks.
Present invention additionally comprises some such architectural features：
