Abstract

The invention provides equipment for demarcating the zero position mounting angle of a fan blade, and belongs to the technical field of fan blade mounting. The equipment comprises an observation barrel, multiple supports and a vertical adjusting mechanism. The observation barrel is provided with an observation cavity which is through up and down, a demarcating piece and an observation piece are fixed to the observation cavity, and a comparison graph is arranged on the demarcating piece. The upper ends of the supports are used for erecting the observation barrel, and the vertical adjusting mechanism is connected to the lower ends of the supports. According to the equipment for demarcating the zero position mounting angle of the fan blade, by observing whether the projection of the fan bladein a vertical state on the demarcating piece coincides with the comparison graph or not through the observation piece, whether the error of the zero position mounting angle of the fan blade exists ornot can be judged; and the axis of the observation barrel can be in a vertical state through the vertical adjusting mechanism, and the problem about demarcating the zero position mounting angle of the fan blade is solved.

Description

technical field [0001] The invention belongs to the technical field of fan blade installation, and more specifically relates to a device for calibrating the zero installation angle of fan blades. Background technique [0002] As an important branch of new energy, wind energy has attracted widespread attention due to its clean, safe and stable characteristics. A wind turbine is a device that converts wind energy into electrical energy, and the fan blade is one of the core components of the wind turbine. At present, the zero-position installation angle of the fan blade is mainly determined through the correspondence between the fan blade installation angle scale and the fan hub blade hub pointer. However, there is a lack of equipment to calibrate the zero installation angle of the fan blades. Contents of the invention [0003] The purpose of the present invention is to provide a device for calibrating the zero-position installation angle of the fan blade, aiming at solving...
