[0022] The connecting mechanism 6 includes a sliding rod 601, a limiting rod 602, a positioning plate 603, an electric telescopic rod 604, a limiting plate 605 and an insertion rod 606. The sliding rod 601 is located in the sliding groove and is slidably connected, and the sliding rod 601 is fixedly connected with the limiting rods 602 arranged at equal distances.

[0024] The auxiliary starting device for a vertical axis wind power station is described. When the natural wind is relatively small, the fan blade connecting rod 3 drives the first gear 504 to rotate through the driving plate 503 and the rotating rod 502 during the rotation process.

Under normal wind speed, no acceleration processing is required to avoid the overload phenomenon caused by excessive speed of the wind turbine.
