The invention relates to a floating type draught fan foundation, a draught fan and a construction method. The floating type draught fan foundation comprises a tower barrel supporting piece and a plurality of stand column type buoyancy tanks which are arranged below the tower barrel supporting piece and are uniformly distributed by taking the tower barrel supporting piece as a center. Each stand column type buoyancy tank comprises a bottom buoyancy tank and an upper buoyancy tank arranged on the bottom buoyancy tank, and the cross section of the bottom buoyancy tank is larger than that of the upper buoyancy tank. A transverse supporting piece is connected between every two adjacent bottom floating boxes, and an anchor chain is connected on the bottom buoyancy tank. An inclined supporting piece is connected between the upper buoyancy tank and the tower barrel supporting piece. According to the floating type draught fan foundation, the cross section of the bottom buoyancy tank is larger than that of the upper buoyancy tank and the cross section of the stand column type buoyancy tank changes in a stepped mode so that the bottom buoyancy tank can provide large buoyancy, the load actingforce of wave flow on the upper buoyancy tank is reduced, the vertical motion damping of the floating type draught fan foundation is increased and the hydrodynamic performance of the floating type draught fan foundation is optimized.

    本发明涉及一种漂浮式风机基础、风机及施工方法,漂浮式风机基础包括:塔筒支撑件;及多个立柱型浮箱,设于塔筒支撑件的下方并以塔筒支撑件为中心均匀分布;立柱型浮箱包括底部浮箱及设置在底部浮箱上的上部浮箱,底部浮箱的横截面大于上部浮箱的横截面;相邻两个底部浮箱之间连接有横向支撑件,底部浮箱上还连接有锚链;上部浮箱与塔筒支撑件之间连接有斜向支撑件。上述漂浮式风机基础,底部浮箱的横截面大于上部浮箱的横截面,使得立柱型浮箱的横截面呈阶梯式变化,使得底部浮箱可提供较大的浮力,有助于减少波浪流对上部浮箱的载荷作用力,从而有利于增加漂浮式风机基础的垂向运动阻尼,优化了漂浮式风机基础的水动力性能。
