Fabricated assembled truss type ultrahigh tower for wind turbine generator installation
The invention belongs to the field of wind power towers, and particularly relates to an assembly type truss ultrahigh tower for wind turbine generator installation, which comprises a pile foundation section, an assembly mechanism and a wind turbine generator reserved table, the assembling mechanism comprises a plurality of vertical truss vertical rods, connecting bases used for matching are arranged on the upper portions and the lower portions of the truss vertical rods, and the adjacent truss vertical rods are connected through truss transverse rods. The combined mechanism is additionally arranged to utilize the ends of the truss vertical rods, external double reinforcement between the adjacent truss vertical rods can be achieved through the combined mechanism, and the connection stability is improved. The direction adjusting mechanism and the anti-vibration mechanism are arranged, the direction adjusting mechanism and the anti-vibration mechanism are both designed in a rotating mode and rotate in a self-direction-adjusting mode under the influence of airflow, the self-excited vibration frequency generated by rotation of the direction adjusting mechanism and the anti-vibration mechanism at all point positions is disordered and is opposite to the vibration frequency generated by rotation of part of fan blades of the wind turbine generator set, and the problem that a fixed tower and the wind turbine generator set generate resonance can be solved; and the damage to the tower connecting structure caused by resonance loss is reduced.
本发明属于风电塔架领域，具体涉及一种风电机组安装用装配式拼装型桁架式超高塔架，包括分段设置的桩基段、装配机构和风电机组预留台；装配机构包括若干个竖直的桁架竖杆，所述桁架竖杆的上下部设置有用于配合的连接座，相邻的所述桁架竖杆之间通过桁架横杆连接；增设组合机构对桁架竖杆端部利用，组合机构可实现相邻桁架竖杆之间的外部双重加固，提升了连接稳定性。设置调向机构和防振机构，两者均为旋转设计，受气流影响自身调向旋转，各点位调向机构和防振机构旋转产生的自激振动频率是无序的，与风电机组部分风叶旋转产生的振动频率对冲，可解决固定的塔架与风电机组部分发生共振的问题，降低了共振损耗塔架连接结构的危害。
