The invention relates to the technical field of wind driven generators, and discloses a main shaft protection device for preventing transverse wind shaking. The main shaft protection device comprisesa cabin, wherein a mounting frame is fixedly connected to the interior of the cabin, a supporting frame is fixedly connected to the interior of the mounting frame, a rotating shaft is rotatably connected to the interior of the supporting frame, fan blades are fixedly connected to the end of the rotating shaft, a coil is fixedly connected to the end, away from the fan blades, of the rotating shaft,permanent magnets are fixedly connected to the two sides of the mounting frame, weather foils are rotationally connected to the two ends of the surface of the cabin, and transmission gears are fixedly connected to the lower ends of the weather foils. A rolling gate is opened, the fan blades rotate to drive the coil to rotate, the permanent magnets are movably connected to the two sides of the coil, the coil is connected with an electromagnetic column, and a magnetic block is fixedly connected to the side, close to the electromagnetic column, of a fan blade frame, so that when transverse windoccurs, the fan blade frame can be retracted, the contact area between the fan blade frame and the cabin is increased, and the vibration effect of rotor blades is reduced.
本发明涉及风力发电机技术领域，且公开了一种防止横向风抖动的主轴保护装置，包括机舱，所述机舱的内部固定连接有安装架，所述安装架的内部固定连接有支撑架，所述支撑架的内部转动连接有转轴，所述转轴的端部固定连接有扇叶，所述转轴远离扇叶的一端固定连接有线圈，所述安装架的两侧固定连接有永磁体，所述机舱表面的两端转动连接有风标，所述风标的下端固定连接有传动齿轮。通过卷闸门打开，扇叶转动带动线圈转动，线圈的两侧活动连接有永磁体，线圈与电磁柱连接，风叶架靠近电磁柱的一侧固定连接有磁块，从而达到了在发生横向风时，能够将风叶架收回，增加了风叶架与机舱接触面积，减少了转子叶片震动的效果。
