Abstract
The utility model relates to a device of pipeline, in particular to suppression device is swashed in rotatable pterygoid lamina formula pipeline whirlpool. Including sleeve shell, vortex pterygoid lamina, pipeline, the spacing closing plate of kingpin, needle roller cage, cylinder kingpin, vortex pterygoid lamina and the welding of sleeve shell, needle roller cage and the coaxial assembly of pipeline arrange in between sleeve shell and the pipeline, among the cylinder kingpin embedding needle roller cage, the spacing closing plate of kingpin hug closely the spacing closing plate of kingpin installation. Overcome the tradition and pressed down the shortcoming that whirlpool device inhibitory effect is poor, weakened the transverse force of ocean current to the pipeline to disturb pipeline rear portion ocean current, reached the effect that restraines the whirlpool and swash.
Description
Technical field
The utility model relates to a kind of device for pipeline, and particularly restraining device is swashed in one rotatable flange plate type pipeline whirlpool.
Background technique
Along with the development of China Petroleum, the exploitation of offshore oil is more and more general with exploitation, and the use of submarine pipeline is also day by day universal.But under flowing state at the bottom of Complex Sea, submarine pipeline easily produces unsettled, and produces vortex-induced vibration under action of ocean current, accelerate the fatigue damage of pipeline.With regard to current technical specifications, the pipeline of damage produces huge negative effect by offshore oil operation, and it is also abnormal difficult to change specific pipeline section.
Current existing whirlpool is swashed restraining device and is mainly concentrated on vertical standpipe, and only has some fixing disturbing flow devices to the submarine pipeline span by horizontal incoming flow, and by incoming flow angle limits, it is limited that inhibition is swashed in whirlpool.
Model utility content
The utility model is intended to solve the problem, provide a kind of rotatable flange plate type pipeline whirlpool and swash restraining device, overcome the shortcoming of traditional eddy suppressor inhibition difference, weaken the transverse force of ocean current to pipeline, and upset pipeline rear portion ocean current, reach the effect suppressing whirlpool to be swashed, its technological scheme adopted is as follows:
Restraining device is swashed in a kind of rotatable flange plate type pipeline whirlpool, comprise sleeve shell, Turbulent wing panel, pipeline, needle roller position limiting sealed plate, cages for needle, cylinder needle roller, described Turbulent wing panel welds with sleeve shell, cages for needle and pipeline coaxially assemble, be placed between sleeve shell and pipeline, described cylinder needle roller embeds in cages for needle, and described needle roller position limiting sealed plate is close to needle roller position limiting sealed plate and is installed.
Described sleeve shell inwall and pipeline outer wall are all by cylinder needle roller dimensioned needle roller groove.
Described Turbulent wing panel has many groups and length is all different, the spaced winding axle center phase difference 30 ° that Turbulent wing panel is often organized.
Beneficial effect: restraining device is swashed in a kind of rotatable flange plate type pipeline whirlpool, overcomes the shortcoming of traditional eddy suppressor inhibition difference, weakens the transverse force of ocean current to pipeline, and upset pipeline rear portion ocean current, reaches the effect suppressing whirlpool to be swashed; The flow field, seabed that change in flow is larger can be adapted to, and can tackle and carry out flow path direction arbitrarily, be applicable to the flow field, seabed flowing to change, reach best whirlpool and swash and suppress object.

Symbol description
1. sleeve shell, 2. Turbulent wing panel, 3. pipeline, 4. needle roller position limiting sealed plate, 5. cages for needle, 6. cylinder needle roller.
Embodiment
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
As Figure 1-3: restraining device is swashed in a kind of rotatable flange plate type pipeline whirlpool, comprise sleeve shell 1, Turbulent wing panel 2, pipeline 3, needle roller position limiting sealed plate 4, cages for needle 5, cylinder needle roller 6, described Turbulent wing panel 2 welds with sleeve shell 1, cages for needle 5 and pipeline 3 coaxially assemble, be placed between sleeve shell 1 and pipeline 3, described cylinder needle roller 6 embeds in cages for needle 5, and described needle roller position limiting sealed plate 4 is close to needle roller position limiting sealed plate 4 and is installed.
Above-mentioned sleeve shell 1 inwall and pipeline 3 outer wall are all by cylinder needle roller 6 dimensioned needle roller groove.
Above-mentioned Turbulent wing panel 2 has many groups and length is all different, the spaced winding axle center phase difference 30 ° of the every group of Turbulent wing panel 2.
Specific works mode: under the operating mode of seabed, ocean current constant impingement pipeline 3, after adding restraining device, the effect of ocean current makes device rotate around pipeline 3 axis, the flow field, pipeline 3 rear portion of disturbance script rule, and when this device rotates, change is continued to the disturbance of ocean current, make ocean current can not produce periodic vibration, reach the object that suppression is swashed in whirlpool.
