The invention discloses a turbulent flow type multi-stage spring damping wind resistance and vibration reduction device, and belongs to high-rise structure wind resistance and vibration reduction equipment. A traction adjusting mechanism composed of a left shaft seat, a left inner threaded sleeve, a left ring, a non-conductive left rope, a left thrust bearing, a left outer threaded shaft, a right shaft seat, a right ring, a right inner threaded sleeve, a right outer threaded shaft and a non-conductive right rope is installed on an H-shaped frame composed of a transverse plate, an upper longitudinal plate and a lower longitudinal plate. The second-stage damping vibration attenuation system is composed of a T-shaped plate, transverse shafts A and B, longitudinal shafts A and B, first-stage spring damping sleeves A and B, first-stage spring damping cover plates A and B, first-stage springs A, B, C and D, guide rail plates A, B, C and D, second-stage spring damping rods A and B, second-stage spring damping sleeves A and B, second-stage springs A and B and damping oil; when the device is used for wind resistance and vibration reduction of a high-rise structure, the change of lateral dynamic stiffness of the high-rise structure is realized, the whole device can synchronously rotate by 360 degrees around the axes of the left non-conductive rope and the right non-conductive rope under the action of natural wind, and the turbulent flow effect is good.
扰流式多级弹簧阻尼抗风减振装置属于高耸结构抗风减振设备；在由横板与上、下纵板组成H型框架上分别安装由左轴座、左内螺纹套、左环、非导电左绳索、左推力轴承、左外螺纹轴和右轴座、右环、右内螺纹套、右外螺纹轴、非导电右绳索组成的牵拉调节机构，由T型板及横轴A、B、纵轴A、B、一级弹簧阻尼套筒A、B、一级弹簧阻尼盖板A、B、一级弹簧A、B、C、D和导向轨道板A、B、C、D、二级弹簧阻尼杆A、B、二级弹簧阻尼套筒A、B、二级弹簧A、B及阻尼油组成的二级阻尼减振系统；本装置在进行高耸结构的抗风减振时，实现了高耸结构侧向动刚度的变化，在自然风作用下整个装置可同步绕非导电左、右绳索轴线360°回转，扰流效果好。
