Description
Technical field
The present invention relates to a kind of ocean platform standpipe anticollision device, collision-prevention devices, are mainly used in ice formation ocean engineering field.
Background technique
The long-term adrift sea ice on the sea of Han Qu, under the driving of wind and stream, sea ice can move therewith, and can
It can cause the destruction of offshore engineering structure.
Standpipe is the main connection between floating ocean platform and subsea wellheads, therefore in the design of the standpipe of Han Qu, is needed
Consider that sea ice influences the collision of vertical tube structure, avoids sea ice from damaging vertical tube structure, to guarantee its normal sustained service.
At the initial stage being designed, based on sea ice load data often have certain gap with actual conditions, lead to the anti-ice of standpipe
Jolt capacity is insufficient, so, it is very necessary for carrying out effective protection to ocean platform vertical tube structure.
Summary of the invention
One is provided the purpose of the invention is to improve the impact resistant capability of the standpipe between ocean platform and subsea wellheads
Kind ocean platform standpipe anticollision device, collision-prevention device.
The technical solution adopted by the present invention is that:
A kind of ocean platform standpipe anticollision device, collision-prevention device, including rolling bearing 2, buffering ring 3 and sleeve 5, the rolling bearing 2
Inner ring is connect with 1 outer wall of standpipe；The buffering ring 3 is arranged between the rolling bearing 2 and sleeve 5, and sleeve is mounted on
Outermost.
The invention also includes features some in this way:
1, the buffering ring 3 is made up of rubber pneumatic bag the link of chain 4.
2,5 outer wall surface of sleeve offers guide thread conduit 6.
Compared with prior art, the beneficial effects of the present invention are:
Sleeve outer surface of the present invention is provided with guide thread conduit, to play guiding role to sea ice, and reduces wave pair
The impact of whole device；
The present invention can carry out multistage energy consumption by rubber pneumatic bag and rotating device, when extending the effect of sea ice and standpipe
Between, greatly reduce the energy exchange between sea ice and standpipe, so that direct active force, simultaneous buffering suffered by standpipe be greatly decreased
Ring can also provide buoyancy for whole device, float on whole device always at water surface neighbouring position, to realize to standpipe
Anti-bumping protection effect；
The present invention good, safe and reliable, advantages of simple structure and simple with anti-collision effect.
Detailed description of the invention
Structure chart Fig. 1 of the invention；
Top view Fig. 2 of the invention.
Specific embodiment
Present invention is further described in detail with reference to the accompanying drawing:
As shown in Fig. 1~2: a kind of ocean platform standpipe anticollision device, collision-prevention device includes rolling bearing 2, buffering ring 3 and sleeve 5.Its
The inner ring of middle rolling bearing 2 connect installation with 1 outer wall of standpipe, to guarantee that device can be rotated under effect of impact, plays certain consumption
It can effect；Buffering ring 3 by several rubber pneumatic bags by chain connection form, and by chain 4 be connected to 2 outer ring of rolling bearing with
Between 5 inner wall of sleeve, impact buffer function can be played, moreover it is possible to provide buoyancy for whole device；Sleeve 1 is mounted on outermost,
Its outer surface is provided with guide thread conduit 6, to play guiding role to sea ice, and reduces impact of the wave to whole device.
A kind of ocean platform standpipe anticollision device, collision-prevention device, the multistage annular anticollision device, collision-prevention device that consumes energy arranged along standpipe lateral profile,
It can float automatically across the sea.When device by sea ice hit when, sea ice acted on sleeve outer wall before this, make whole device along
Crash direction continues to move, while the buffering ring being located on the inside of sleeve can play buffer function, and carry out jointly with rolling bearing
Multistage energy consumption, extends the action time of sea ice and standpipe, substantially reduces the energy exchange between sea ice and standpipe, be greatly decreased vertical
The suffered active force of pipe is realized and is acted on the Anti-bumping protection of standpipe.
The present invention can carry out multistage energy consumption by buffering ring and rotating device, so that sea ice suffered by standpipe be greatly reduced
Direct active force, simultaneous buffering ring can also provide buoyancy for whole device, whole device made to float on water surface neighbouring position always
Place acts on the Anti-bumping protection of standpipe to realize；The present invention good, safe and reliable, advantages of simple structure and simple with anti-collision effect.
