3. the whirlpool vibration suppressing method that a kind of magnetic force swing is combined with water conservancy diversion rotation, is revolved using magnetic force as described in claim 1
It puts the whirlpool vibration combined with water conservancy diversion rotation and inhibits device, it is characterised in that: deposited between the embedded wavy water-stop sheet of magnet (15) and ocean current
In the angle of attack, the embedded wavy water-stop sheet of magnet (15) rotates under the impact of ocean current, while postposition sleeve (4) and windowing are drawn
Flow preposition sleeve (3) rotation, until the embedded wavy water-stop sheet of magnet (15) around to marine riser (1) back stream side and with ocean current stream
To in same plane；Ocean current is flowed into from the drainage window (10) of the preposition sleeve of Fenestration drainage (3), by fish mouth branching block (12)
Water conservancy diversion convergence effect, seawater flow to the drainage conduit of postposition sleeve (4) along the interior empty channel of the preposition sleeve of Fenestration drainage (3)
(9) it in, impacts on impeller (13), impeller (13) rotation drives screw rod (6) rotation；Since fish mouth branching block (12) is to introducing
Ocean current play convergence effect, into drainage conduit (9) water velocity increase, make impact screw rod (6) fluid dynamic energy increase
By force；The screw rod (6) of rotation brings disturbance to back wake flow, and screw rod (6) is in marine riser (1) around plane of flow
It is the boundary layer point that middle high reynolds number marine riser streams herein at 120 ° (angle with incoming flow immediately ahead of marine riser (1))
From point, thus the screw rod (6) rotated disturbs the separation in boundary layer；The ocean current for flowing through impeller (13) is finally exported from aerial drainage
(11) it sprays, the wake zone that the ocean current ejected carries on the back stream side to marine riser (1) is filled with momentum, rushes tail portion vortex
It hits, destroys the development of vortex；In addition, ocean current impacts on the embedded magnet swinging mounting for be equipped with bar magnet (7) (5),
Push embedded magnet swinging mounting (5) to slide to the wavy water-stop sheet of embedded magnet (15), with embedded magnet swinging mounting (5) with
The spacing of the embedded wavy water-stop sheet of magnet (15) constantly reduces, and the bar magnet (7) for embedding (15) on the wavy water-stop sheet of magnet is right
The repulsive force that bar magnet (7) on embedded magnet swinging mounting (5) generates is bigger, pushes embedded magnet swinging mounting (5) anti-
To sliding, the embedded magnet swinging mounting (5) in swinging sliding slot (8) toward polyslip destroys falling off and sending out for wake zone vortex
Exhibition, while the flow-disturbing column (14) of embedded magnet swinging mounting (5) end produces depth disturbance to wake zone flow field；Part sea
Water is directed to the adjacent embedded magnet swinging mounting (5) of screw rod (6) under the centrifugal force effect of the screw rod (6) of rotation
Near, deploy seawater spatially；The embedded wavy water-stop sheet of magnet (15) separates back side water flow, has divided tail
The development space of area's vortex is flowed, to inhibit the development of vortex, and near the embedded wavy water-stop sheet of magnet (15) running surface
Flow direction constantly adjusted；Thus, it is ejected in drainage window (10) and drainage conduit (9) water conservancy diversion, aerial drainage outlet (11)
Stream, screw rod (6) rotation, embedded magnet swinging mounting (5) reciprocally swinging, the embedded wavy water-stop sheet of magnet (15) segmentation flowing are empty
Between and adjustment flow direction collective effect under, make marine riser (1) around laminar boundary layer by depth destroy, change boundary layer separation
Point destroys the three-dimensional structure of wake flow vortex, it is suppressed that the formation and development of vortex, to realize the vortex-induced vibration of Non-energy-consumption
Inhibit.
