Abstract

The present invention relates to a kind of standpipe vortex-induced vibration Omnidirectional rotation turbine flow-disturbing vibration-repressing device, the invention belongs to marine riser vibration suppression field, it is related to one kind effectively to suppress standpipe vortex-induced vibration, increases the vibration-repressing device in riser fatigue life-span.The device includes polyvinyl chloride sleeve, and blade, bearing, 3 blades are symmetrically arranged on sleeve outside, are 60 ° with the angle of pipeline tangential direction, and the bearing of built-in compressible steel ball, bearing inner side fixed riser are installed in sleeve inner side.The device is not limited by direction of flow, to complicated well adapting to property of deepwater environment.It is out-of-date to circulate outside, and disturbance flow field, destruction vortex shedding are reached by rotating freely, and reduces standpipe vibration amplitude, improves the purpose of fatigue life.Simple structure of the present invention, installation procedure is simple, has good suppression efficiency to the vortex-induced vibration of marine riser.

Description

A kind of standpipe vortex-induced vibration Omnidirectional rotation turbine flow-disturbing vibration-repressing device

Technical field

The invention belongs to marine riser vibration suppression field, and in particular to a kind of standpipe vortex-induced vibration Omnidirectional rotation turbine flow-disturbing vibration-repressing device.

Background technology

In deepwater field development system, marine riser is the connecting pipe of offshore platform and subsea wellheads, generally has more than ten standpipes on a platform, and length can reach several kms, Deepwater Risers slenderness ratio is very big, and center section is again without other any fixed supports in addition to upper and lower side;Also allowing for standpipe has work under bad environment, and stress is extremely complex, is the high-tech job facilities of deep-sea engineering the features such as construction cost is huge, is also one of job facilities of weak rapid wear.Under the external environment condition load action such as wave, ocean current, standpipe can occur vortex-induced vibration, be the main inducing that riser fatigue is damaged though vortex-induced vibration will not destroy at once standpipe.And standpipe is once destroyed, huge economic loss will be caused and trigger serious marine pollution and secondary disaster.Therefore, in the design of standpipe, how to mitigate vortex-induced vibration, extend the tired service life of marine riser, be the focus of various countries' engineering circles concern.It is main using the additional vibration-repressing device on the outside of standpipe in the world at present, i.e., the formation of whirlpool is destroyed by changing works surface configuration or adding other devices on works surface, so as to suppress vortex-induced vibration.

The content of the invention

The object of the invention is directed to riser vortex excited vibration, designs a kind of Omnidirectional rotation turbine flow-disturbing vibration-repressing device, realizes good suppression efficiency, effectively reduces standpipe amplitude.

To achieve the above object, the technical solution adopted by the present invention is:The device includes polyvinyl chloride sleeve, blade, bearing, 3 blades are symmetrically arranged on sleeve outside, it it is 60 ° with the angle of pipeline tangential direction, the bearing of built-in compressible steel ball, bearing inner side fixed riser are installed in sleeve inner side, the device is not limited by direction of flow, to complicated well adapting to property of deepwater environment.When outflow is acted on, disturbance flow field, destruction vortex shedding are reached by rotating freely, reduce standpipe vibration amplitude, improve the purpose of fatigue life.

Brief description of the drawings

Fig. 1 is overall structure diagram of the invention.

Wherein 1-polyvinyl chloride sleeve, 2-blade, 3-bearing, 4-standpipe.

Specific embodiment

As shown in figure 1, a kind of standpipe vortex-induced vibration Omnidirectional rotation turbine flow-disturbing vibration-repressing device, device includes polyvinyl chloride sleeve 1, blade 2, bearing 3.Blade 2 is symmetrically arranged on sleeve outside, totally 3, after blade 2 is connected with vinyl chloride sleeve 1 using built-in mantle fiber, surface junction is fixed using high-strength and waterproofing glue, and blade 2 is 60 ° with the angle of pipeline tangential direction, and the bearing of built-in compressible steel ball is installed in sleeve inner side, bearing inner side fixed riser, when there is outflow to pass through, device is free to rotate, realizes omni-directional flow-disturbing.
