Description

The gear-driving butt joint locking mechanism of subsea control modules
Technical field
The present invention relates to a kind of butt joint locking mechanism, particularly relate to a kind of gear-driving butt joint locking mechanism of subsea control modules, belong to Offshore Engineering field.
Background technology
Along with recovery and the constantly growth of global economy, people also constantly increase for oil demand.The world energy sources development prediction that International Energy Agency (IEA) is issued, from 2000 ~ the year two thousand thirty, world petroleum demand amount can increase with the speed in year 1.6%, will reach 57.69 hundred million tons to the year two thousand thirty; The demand of natural fuels will increase with the speed in year 2.4%, will reach be equivalent to 42.03 hundred million tons of oil masses to the year two thousand thirty.The energy on conventional land can not meet the great demand that the mankind bring because of social development, and therefore the paces of the mankind have also progressively been marched toward from land ocean.
In recent years, global ocean oil-gas exploration development is swift and violent, has turned to region, deep-sea (depth of water more than 500 is defined as deep-sea) to expand gradually from the neritic area within 300 meters.Deepwater drilling maximum water depth known has at present reached 3053 meters, and the exploitation depth of water reaches 2292 meters.But at present from the whole world, really have seafari equipment and the country possessing development ability cans be counted on one's fingers.With regard to submerged production production system, its production supplier concentrates on the Systems in Certain Developed Countries such as the U.S., Norway mostly.
Subsea control modules (SCM) is the nucleus equipment of Subsea Control Systems, SCM controls each valve on subsea production tree, the state of monitoring christmas tree, and in time to the equipment feedback undersea device information on sea, and the co-ordination of water surface production platform and subsea production system is also realized by subsea control modules.Usual subsea control modules installs basal disc carry out locking with control module waterborne and be directly installed on the equipment that will control, as: subsea production tree, subsea manifold etc.
At present, the version of the existing many employings of catch gear under water dynamic seal, medium lock mandrel is utilized to lock, apply in supporting diving and deepwater environment, but due to its complex structure, and a lot of dynamic seal only when mechanism's high-speed operation competence exertion go out its sealing property, so be not suitable for being applied on subsea control modules.Static seal structure can not only reduce working accuracy and the assembly precision of part effectively, and when static seal catch gear works, leakproofing material can not be worn, therefore static seal catch gear often has longer service life than movable sealing structure.
At present, existing underwater mating catch gear has number of different types, control locking and conciliate lock control principle majority employing worm drive mechanism, no matter be dynamic seal or static seal, its hermetically-sealed construction is mainly all arranged on lock shaft, the multiple locating dowel pin of the docking many employings of guiding mechanism carries out guide-localization, and guide finger requires that the precision of processing and assembling is very high, often occurs the situation that docking is stuck.And catch gear many employings rotation lock mandrel promotes lock shaft, easily there is stuck situation in this kind of locking mechanism structure complexity.
Summary of the invention
Main purpose of the present invention is the above-mentioned technical disadvantages overcoming prior art existence, and a kind of gear-driving butt joint locking mechanism of subsea control modules is provided, not only can cancel the lock shaft in subsea control modules, but also eliminate two seals device, improve system reliability.
The object of the present invention is achieved like this: the pedestal comprising subsea control modules docking main body and be arranged on subsea equipment, the center of described pedestal is provided with lower sleeve, described pedestal is provided with hydraulic pressure public plug and pedestal electric connection, and the lower end of pedestal is also provided with lock sleeve, lock sleeve is provided with locking slot, described subsea control modules docking main body comprises housing, be arranged on the upper plate of housing upper end and be arranged on the lower shoe of housing lower end, described upper plate is provided with suspension ring body, suspension ring body is provided with suspension ring, described lower shoe outer ring is provided with binding ring, binding ring is provided with locking pin, described locking pin coordinates with locking slot, the outside face of described binding ring is provided with tooth-shape structure, described tooth-shape structure is driven by mounting tools by under-water robot, the center of described lower shoe is provided with locating bush, the end of locating bush is provided with stifled ring, the outside face of described locating bush is provided with feather key, the inside face of described lower sleeve is provided with guide groove, and feather key coordinates with guide groove, described lower shoe is also provided with and coordinates hydraulic pressure female and lower shoe electric connection with the hydraulic pressure public plug on pedestal and pedestal electric connection respectively.
