A bridge cable that can suppress wind and rain-induced vibration

Abstract

The invention discloses a bridge cable capable of suppressing wind-induced vibration. The bridge cable comprises a stay cable body, wherein the stay cable body is provided with a plurality of windshield wiper devices in sequence in the length direction of the stay cable body, each windshield wiper device comprises a shell sleeving the stay cable body and a power supply device, a rain sensor, a driving device and a brush body which are arranged on the corresponding shell; the driving devices are connected with the shells and the brush bodies separately and drive the brush bodies to rotate around the surface of the stay cable body; the driving device and the rain sensors are connected with the power supply devices separately. The bridge cable capable of suppressing the wind-induced vibrationhas the advantages that the windshield wiper devices can be widely applied to the stay cable bodies of different diameters and different inclination angles, the windshield wiper devices are not turned on when it does not rain, the windshield wiper devices are turned on when it rains, the rotation speed can be automatically adjusted according to the rainfall amount, and the windshield wiper devices continuously damage the formation of water lines on the stay cable body, thereby reducing or even avoiding the damage to the stay cable body of the wind-induced vibration.

Description

technical field [0001] The invention relates to the technical field of bridge cables, in particular to a bridge cable capable of suppressing vibration induced by wind and rain. Background technique [0002] As a cable system, the cable-stayed bridge has a larger spanning capacity than the girder bridge, and is the most important type of long-span bridge. At present, the cable-stayed bridge with the largest span built in the world is Russia's Russky Island Bridge, with a main span of 1,104 meters, and the main span of my country's Sutong Yangtze River Bridge is also 1,088 meters. With the continuous increase of the span of cable-stayed bridges and the length of cables (the longest length is about 578m), the problem of wind-induced vibration of cables of cable-stayed bridges is becoming more and more serious, especially the problem of wind and rain-induced vibration of cables. The vibration of the cable will cause a series of serious consequences such as fatigue damage of the...
