Abstract

The invention discloses a vortex-induced vibration suppression device and method capable of being quickly assembled and disassembled. The device mainly comprises an automatic winding-unwinding storagewinch and the like. The automatic winding-unwinding storage winch is coaxially arranged on an armored cable in a sleeving mode and moves in the axial direction. A flow guide ribbon is wound and stored in the automatic winding-unwinding storage winch, the two tail ends of the flow guide ribbon are fixed to the armored cable through hoops, a rope arrangement rotating ring and a belt rope rotating ring are coaxially installed on the automatic winding-unwinding storage winch, and the flow guide ribbon is guided, positioned, released and recycled through the rope arrangement rotating ring and thebelt rope rotating ring. Vortex-induced vibration suppression effects of the diversion ribbons and the spiral strakes are comprehensively used, and vortex-induced vibration of the armored cable in water can be effectively suppressed; quick assembly and disassembly and high use efficiency are achieved; the spiral angle and the screw pitch formed by the diversion ribbons on the armored cable can beadjusted at any time, so that the applicability is high; the flow guide ribbon covers the armored cable by 360 degrees; and the vortex-induced vibration suppression device is also suitable for marinerisers, marine platform jackets and other cylindrical structures in ocean engineering and used for suppressing vortex-induced vibration.

Description

technical field [0001] The invention relates to the field of marine engineering, in particular to a vortex-induced vibration suppression device and method that can be quickly loaded and unloaded. Background technique [0002] Armored cable is a common connection method between ships and underwater towed bodies. It is used for the transmission of underwater towed power and signals. The armored cable withstands marine environmental loads such as wind, waves, and currents during the working process. Under a certain flow rate, when waves and ocean currents flow through the armored cable, alternate vortices will be generated behind the armored cable. Periodic vibration occurs in the water flow direction and the vertical water flow direction, and the vibration frequency is related to the flow rate and the diameter of the armored cable. At the same time, the vibration of the armored cable will also affect the flow field, which will increase the vortex and increase the resistance. ...
