Vibration reduction early warning device and early warning method used outside stay cable plane
The invention belongs to the technical field of stay cable damping vibration attenuation, and particularly relates to a vibration attenuation early warning device and early warning method used outside a stay cable plane. The device comprises a damping box, wherein a planetary gear train is arranged in a cylindrical cavity of the damping box; the rotating shaft radially extends to form a lower connecting rod, the extending section of the lower connecting rod is hinged to an upper connecting rod, the upper connecting rod is hinged to a connecting block fixed to the stay cable, and the axis of each hinged position is parallel to the axis of the rotating shaft; the rotating shaft is also provided with conductive energy-consuming rotors, and the energy-consuming rotors and the rotating shaft are insulated from each other. In the axial direction of the rotating shaft, a cylinder cavity space between the adjacent conductive energy-consuming rotors is filled with damping liquid; the two ends of the rotating shaft are further provided with magnets for the conductive energy consumption rotor to cut magnetic induction lines, and the magnitude of current generated after the magnetic induction lines are cut is obtained through the current sensor. A basic platform can be provided for monitoring and early warning of the vibration amplitude of the stay cable in the working process, so that the purpose of ensuring stable and reliable operation of the stay cable is achieved, and safety accidents caused by over-amplitude vibration of the stay cable are avoided.
本发明属于斜拉索阻尼减振技术领域，具体涉及一种用于斜拉索平面外的减振预警装置及预警方法。本发明包括阻尼箱，阻尼箱的筒腔内布置行星轮系；转轴处径向延伸有下连杆，下连杆的延伸段铰接上连杆，上连杆铰接于固定在斜拉索上的连接块处，各铰接处轴线均平行转轴轴线；转轴上还设置导电耗能转子，且各耗能转子与转轴之间彼此绝缘；在转轴轴向上，相邻导电耗能转子之间的筒腔空间填充阻尼液；转轴两端还布置有可供导电耗能转子切割磁感线的磁铁，并通过电流传感器获得切割磁感线后产生的电流量。本发明能为斜拉索在工作过程中的振动幅度的监控和预警提供基础平台，从而确保斜拉索的稳定可靠运行目的，避免因斜拉索超幅振动而发生安全事故。
