Document Type and Number:
WIPO Patent Application WO/2022/012001
Kind Code:
A1
Abstract:
Disclosed is a bridge vortex-induced vibration control device, comprising a control unit, which is arranged at the bottom of a bridge and comprises several controllers, each of which comprises a base (4) and several sliding plates (9), wherein the base (4) is provided with a sliding groove in the lengthwise direction, with a wedge block (7) being slidably arranged in the sliding groove; two sides of the base (4) are provided with several slide holes, in which the sliding plates (9) are arranged; an end of the sliding plate (9) is provided with a wedge face matching the wedge block (7); and the bottom of the sliding plate (9) is provided with a wind shield structure, which comprises a first connecting rod (15), a second connecting rod (16), a third connecting rod (17) and a wind shield curtain (18), with the first connecting rod (15) and the second connecting rod (16) both being hinged to the bottom of the sliding plate (9), two ends of the third connecting rod (17) being respectively hinged to the first connecting rod (15) and the second connecting rod (16), and the wind shield curtain (18) being quadrangular and three sides thereof being respectively arranged on the first connecting rod (15), the second connecting rod (16) and the third connecting rod (17). The device can solve the technical problem of the possible generation of vortex-induced vibration in a bridge under low wind speeds.
