Description
Technical field
A kind of a kind of gear-driving docking the present invention relates to butt joint locking mechanism, more particularly to subsea control modules is locked
Tight mechanism, belongs to Offshore Engineering field.
Background technology
With the recovery and constantly growth of global economy, people are also continuously increased for oil demand.International Energy Agency
(IEA) the world energy sources development prediction of issue, from 2000~the year two thousand thirty, world petroleum demand amount can be entered with the speed in year 1.6%
Row increases, and 57.69 hundred million tons are up to the year two thousand thirty；The demand of natural gas will be increased with the speed in year 2.4%, to the year two thousand thirty
It is up to equivalent to 42.03 hundred million tons of oil masses.The energy on conventional land can not meet what the mankind brought by social development
Great demand, therefore the paces of the mankind have also progressively marched toward ocean from land.
In recent years, global ocean oil-gas exploration development is swift and violent, and the neritic area within 300 meters is increasingly turned to blue water
(the defined above as deep-sea of the depth of water 500) is expanded.Up to 3053 meters, the exploitation depth of water reaches the deepwater drilling maximum water depth being currently known
2292 meters.But at present from the point of view of the whole world, the country for really possessing seafari equipment and possessing development ability cans be counted on one's fingers.Just
For submerged production production system, its production supplier has focused largely on the Systems in Certain Developed Countries such as the U.S., Norway.
Subsea control modules (SCM) are the nucleus equipment of Subsea Control Systems, each valve on SCM control subsea production trees
Door, monitors the state of production tree, and in time to the equipment feedback undersea device information on sea, and water surface production platform and water
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, locked using middle lock shaft using the structure type of dynamic sealing more than existing retaining mechanism under water,
Applied in supporting diving and deepwater environment, but due to its complex structure, and many dynamic sealings are only when mechanism runs at high speed
Wait competence exertion and go out its sealing property, so being not suitable for being applied on subsea control modules.Static seal structure can not only be effective
Ground reduces the machining accuracy and assembly precision of part, and, when static seal retaining mechanism works, encapsulant will not be ground
Damage, therefore static seal retaining mechanism often has 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 the precision of guide finger requirement processing and assembling is very high, often occurs
The stuck situation of docking.And lock shaft is lifted more than retaining mechanism using rotation lock mandrel, this kind of locking mechanism structure is complicated, holds
Easily there is stuck situation.
The content of the invention
It is a primary object of the present invention to the above-mentioned technical disadvantages for overcoming prior art to exist, and provide a kind of underwater control
The gear-driving butt joint locking mechanism of module, can not only cancel the lock shaft in subsea control modules, but also save
Two seals devices, improve system reliability.
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 hydraulic pressure public plug and pedestal electric connection are provided with the pedestal, and
The lower end of pedestal is also equipped with lock sleeve, and locking slot is provided with lock sleeve, and the subsea control modules docking main body includes shell
Body, the upper plate installed in housing upper end and the lower shoe installed in housing lower end, suspension ring body is provided with the upper plate, is hung
Suspension ring are installed, the lower shoe outer ring is provided with retaining ring in ring body, locking pin are installed in retaining ring, the locking pin with
Locking slot coordinates, and the outer surface of the retaining ring is provided with tooth-shape structure, and the tooth-shape structure is by underwater robot by installing
Tool drives, the center of the lower shoe is provided with positioning sleeve, and the end of positioning sleeve is provided with blocking ring, the positioning sleeve
Feather key is provided with outer surface, the inner surface setting of the lower sleeve has gathering sill, and feather key coordinates with gathering sill, described
Be additionally provided with lower shoe respectively with pedestal on hydraulic pressure public plug and pedestal electric connection coordinate hydraulic pressure female and lower shoe electricity
Joint.
Present invention additionally comprises such some architectural features：
