Offshore wind power jacket structure with additional viscous dampers
The invention discloses an offshore wind power jacket structure with additional viscous dampers, and relates to the field of offshore wind power. The offshore wind power jacket structure comprises four jacket leg columns which are uniformly distributed by taking a wind turbine tower as a center, the jacket leg columns are obliquely arranged outwards from top to bottom to form a square conical structure, transition connecting sections used for supporting a wind turbine are fixed to the top ends of the jacket leg columns through inclined supporting rod pieces connected to the viscous dampers in series, and any two adjacent jacket leg columns serving as main supports are connected into a whole through a plurality of inclined supporting sets arranged in the height direction, the each inclined supporting set is composed of two inclined supporting rod pieces which are connected to the viscous dampers in series and arranged in a crossed mode in a welding mode, flange plates are arranged at one ends of the inclined supporting sets and one ends of the viscous dampers in the inclined supporting rod pieces, the ends of the viscous dampers in the inclined supporting rod pieces are connected to the viscous dampers in series, flange plates are arranged at one ends of the inclined supporting rod pieces in a casting mode, the flange plates and the flange plates are connected bolts, the other ends of the viscous dampers are piston rods, and the other ends of the viscous dampers and the other ends of the inclined supporting rod pieces are connected to the jacket leg columns in a welded mode. According to the offshore wind power jacket structure, the anti-vibration performance is obviously improved with lower cost.
一种附加粘滞阻尼器的海上风电导管架结构涉及海上风电领域，包括四个以风机塔筒为中心均匀分布的导管架腿柱，导管架腿柱由上至下向外倾斜设置成方锥形结构，用于支撑风机的过渡连接段与导管架腿柱顶端通过与粘滞阻尼器串联的斜撑杆件固定，任意相邻的两个作为主支撑的导管架腿柱之间通过沿高度方向设置的多个斜撑组连接成整体，斜撑组由两个与粘滞阻尼器串联的斜撑杆件采用焊接方式交叉设置组成。斜撑组及用于固定过渡连接段的与粘滞阻尼器串联的斜撑杆件中的粘滞阻尼器一端为法兰盘，斜撑杆件一端铸有法兰盘，二者通过螺栓相连接；粘滞阻尼器的另一端为活塞杆，与斜撑杆件的另一端分别与导管架腿柱焊接连接。本发明以较低成本显著提高抗振性能。
