The invention discloses an inclination angle measuring and rechecking method for a floating type wind turbine generator without a yaw structure, which comprises the following steps of: manufacturing a U-shaped piece, tightly attaching the top of the laterally placed U-shaped piece to the lower end surface of a basic flange in the front-back direction, welding and fixing the U-shaped piece, and mounting two same double-shaft inclination angle sensors on the mounting surface of the U-shaped piece, the inclination angle value of the double-shaft inclination angle sensor completely represents the inclination angle of the flange face, a suspension support is installed at the height of the flange face of the foundation, the center of the suspension support is the center of the cross section of the foundation, a steel wire is suspended at the center of the suspension support, and the lower end of the steel wire is connected with a pendant. The center of the reference bracket is the center of a basic section, and the inclination angles of the two sensors are used as reference when the unit normally operates; when the inclination angles of the two sensors are deviated, which abnormity cannot be judged, a mechanical stable reference object is used as a reference. According to the invention, the inclination angle measurement and recheck of the floating wind turbine generator without the yaw structure can be accurately completed.
本发明公开了一种无偏航结构的漂浮式风电机组的倾角测量和复核方法,制作一个U型件,将侧放的U型件顶部紧贴到基础法兰前后方向的下端面并焊接固定,U型件的安装面上安装两个相同的双轴倾角传感器,双轴倾角传感器的倾角数值将完全代表法兰面的倾角,基础的法兰面高度安装一个悬挂支架,悬挂支架中心为基础截面中心,在悬挂支架中心悬挂一根钢丝,钢丝下端连接一个吊坠,在悬挂支架下方安装一个参考支架,参考支架中心为基础截面中心,机组在正常运行时,将使用两个传感器的倾角作为参考;当两个传感器的倾角出现偏差,无法判断哪个异常时,有机械式的稳定的参照物作为参考。本发明可以准确无误地完成无偏航结构的漂浮式风电机组的倾角测量和复核。
