APPARATUS OF MEASURING CENTER OF GRAVITY OF WIND POWER GENERATOR BLADE

摘要

The purpose of the present invention is to provide a device to measure a center of gravity of an aerogenerator blade which measures the center of gravity of a blade in a state of more stably support the blade, and increases a measuring accuracy. A weight measuring unit for a root part measures a weight of a root part by mounting the root part of the aerogenerator blade. Moreover, a weight measuring unit for a tip part is spaced from a weight measuring unit for the root part, and measures a weight of a tip part by mounting the tip part of the blade. In regards to this, the weight measuring unit for the tip part, comprises: a mounting element for the tip part; a plurality of sling bars arranged along a longitudinal direction of the tip part, and mounted on the mounting element for the tip part to cover and support a lower surface of the tip part along with both side surfaces; and a weight measuring part for the tip part mounted on a lower side of the mounting element of a tip part to measure the weight of the tip part supported by the sling bars. In addition, a distance measuring unit measures each distance of a weight measuring position of the root part and a weight measuring position of the tip part from an edge part of the root part. Also, a controller calculates the center of gravity of the blade based on the weight data measured from the weight measuring unit for a root part and the weight measuring unit for a tip part respectively, and the distance data measured from the distance measuring unit.
