The invention provides an offshore floating type draught fan platform and offshore draught fan equipment. The offshore floating type draught fan platform comprises a first stand column, at least two second stand columns, a supporting rod set, a buoy and stand column sleeves. The tops of the first stand column and the second stand column define a supporting plane, and the fan is connected to the top of the first stand column. The first stand column and the second stand column are connected into a whole through the supporting rod set. The buoy is used for providing buoyancy for the platform. And the stand column sleeve sleeves the outer side of the second stand column. Surface vortexes appearing around the stand column are caused by front-back reciprocating oscillating motion of waves around the column body, the effect of oscillating flow can be described by the number # imgabs0, # imgabs1 # and # imgabs2 # are the maximum speed of oscillating water flow, # imgabs3 # is the oscillating period, and # imgabs4 # is the diameter of the stand column. The stand column sleeve is arranged outside the second stand column, so that the diameter # imgabs5 of the position, provided with the stand column sleeve, of the second stand column is increased, the diameter # imgabs6 of the position, provided with the stand column sleeve, of the second stand column is reduced, the energy of waves acting on the surface of the second stand column is reduced, the wave climbing amplitude and the wave disturbance effect are correspondingly reduced, and the air gap response can be effectively reduced.
本发明提供一种海上漂浮式风机平台和海上风机设备,包括第一立柱、至少两个第二立柱、支撑杆组、浮筒和立柱套筒。第一立柱和第二立柱的顶部围成一个支撑平面,风机连接在第一立柱的顶部。支撑杆组将第一立柱和第二立柱连接成一个整体。浮筒用于为平台提供浮力。立柱套筒套设在第二立柱的外侧。立柱周围出现的表面漩涡由波浪绕柱体做前后往复振荡运动所引起的,振荡流的作用可用#imgabs0#数描述,#imgabs1#,其中#imgabs2#为振荡水流的最大速度,#imgabs3#为振荡周期,#imgabs4#为立柱直径。通过在第二立柱的外部设置立柱套筒,使第二立柱设置立柱套筒的位置的直径#imgabs5#增大,#imgabs6#数减小,波浪作用在第二立柱表面的能量减小,波浪爬升幅度和波浪扰动效应也相应减小,可有效减小气隙响应。
