The invention provides a self-adjusting eddy current damping vibration attenuation device for a water surface platform. The self-adjusting eddy current damping vibration attenuation device comprises a bracket, an input shaft, a damping shaft, a copper plate, a plurality of permanent magnets, a chain, a chain wheel and a mass block I, an input shaft and a damping shaft are arranged on the support in parallel, and the input shaft is connected with the damping shaft through a transmission mechanism. A chain wheel is fixedly installed on the input shaft and meshed with a chain, and the two ends of the chain are connected with the mass block I and the seabed respectively. A circular copper plate is fixedly installed on the damping shaft, a plurality of permanent magnets are installed on the support and are close to the copper plate, and the magnetic poles, facing the copper plate, of every two adjacent permanent magnets are opposite. The device is simple and compact in structure, good in reliability, small in occupied space and convenient to install in scenes such as a floating platform with small space; a gear-gear transmission mechanism with two gears is adopted, the cost is reduced through standardized and modularized production of the gears, and meanwhile later maintenance and replacement are facilitated.
本发明提供了一种水面平台自调节式电涡流阻尼减振装置,包括支架、输入轴、阻尼轴、铜板、多个永磁铁、链条、链轮及质量块I;所述的支架上平行设有输入轴和阻尼轴,输入轴与阻尼轴通过传动机构连接;所述的输入轴上固定安装有链轮,链轮与链条啮合,链条的两端分别连接质量块I和海床;所述的阻尼轴上固定安装有圆形的铜板,支架上安装有多个永磁铁,多个永磁铁靠近铜板设置,相邻的两个永磁铁朝向铜板的磁极相反。本发明结构简单、紧凑,可靠性好,占用空间小,便于漂浮平台等空间较小的场景安装;本发明采用两齿轮的齿轮齿轮传动机构,齿轮的标准化和模块化生产降低成本的同时,也方便了后期维护和更换。
