Zero-setting clamp for wind vane of wind generating set and clamping method

The invention discloses a zero-setting clamp for a wind vane of a wind generating set and a clamping method. At present, in the installation of the wind vane of the wind generating set, the wind vane is observed by naked eyes, so that the position deviation is easy to occur, and the power generation efficiency of the wind generating set is influenced. The zero setting device comprises a wind indicator (9), a zero setting clamp is installed on a supporting rod frame of the wind indicator, the zero setting clamp is composed of a fixing base (7) and a supporting base (5), installation holes are formed in the fixing base and the supporting base, long-rod bolt assemblies (8) are inserted into the installation holes, the supporting base and the fixing base are fixedly connected through the long-rod bolt assemblies, a Y-shaped support (1) is connected to the supporting base, and the Y-shaped support (1) is fixedly connected to the supporting base. The supporting seat is connected with a laser generator fixing frame
