The invention discloses a seal rotating structure on a rotating shaft in a wind power generation device. The structure comprises a cabin, the rotating shaft is rotatably connected to the cabin, the rotating shaft and a hub are fixedly connected, an end cover is integrally formed on the hub, a cavity is formed in the hub, a rain cover is fixedly mounted on the cabin, a seal ring is arranged on thehub, a seal bearing is fixedly mounted on the hub, a connecting rod is rotatably connected in the seal bearing, blades are fixedly mounted on the connecting rod, when the structure encounters strong wind, and the strong wind exceeds a certain limit, centrifugal force to a sliding block is increased, elastic force of a spring, and friction force of a second sliding groove are overcome for achievingmoving, a push and pull rod is driven to move, through the lever effect, moment is increased, an arc rack is moved, finally, the aim of automatically adjusting the blades is achieved, an extra motorfor driving is not needed,
