Wind turbine generator meteorological mast convenient to maintain

The invention discloses a wind turbine generator meteorological mast convenient to maintain, which is mainly characterized in that through reasonable arrangement of the positions and the number of connecting points of the meteorological mast, diagonal draw bars and a mounting plane, a stable loading state similar to a triangle is presented in each direction, and meanwhile, at least one bracket bears a tension load, so that the material consumption is reduced, and the maintenance cost is reduced. The bending resistance of the whole structure can be improved; besides, a rotating pair is arranged at each connecting point of the support, the support is allowed to rotate integrally or partially, free switching between the normal working posture and the maintenance posture is achieved, and the difficulty of later operation and maintenance work is reduced. 本发明公开了一种便于维护的风电机组气象桅杆，主要特点在于，通过对气象桅杆、斜拉杆以及安装平面联接点位置及数量的合理布置，在各个方向呈现出类似三角形的稳定受载状态，同时至少有一根支架承受拉力载荷，既减少材料使用量，又能提高整个结构的的抗弯能力；另外，本发明在支架各个联接点设置了转动副，允许支架整体或部分转动，实现正常工作和维
