Abstract

The invention relates to the technical field of the detection of wind driven generator blades, and in particular to a wind driven generator blade surface defect detection method and detection apparatus. The wind driven generator blade surface defect detection method comprises the following steps: acquiring a pressure difference preset value; setting a standard pressure value of a pressure detection module; placing the pressure detection module at an area to be detected of the blade surface, moving the pressure detection module along a set track at the area surface to be detected, and detecting a real-time pressure value of the area surface to be detected by virtue of the pressure detection module; calculating a pressure difference between the real-time pressure value and the standard pressure value; comparing the pressure difference with the pressure difference preset value, and judging a blade surface defect type; and marking the blade surface defect type. The detection method is low in cost, simple in operation, accurate and rapid in detection, and capable of preventing the long detection time of the surface defect from reducing the production of the wind driven generator blade.

Description

technical field [0001] The invention relates to the technical field of detection of wind power generator blades, in particular to a detection method and detection device for surface defects of wind power generator blades. Background technique [0002] With the expansion of my country's wind energy market, the fan manufacturing industry has gradually entered a period of rapid development. Blades are the core components of wind turbines. Blades have technological requirements for surface flatness. The appearance of surface defects such as unqualified air bubbles will change the shape of the blades, thereby affecting the aerodynamic performance of the blades and reducing the power generation efficiency of the unit. [0003] The existing production technology with glass fiber reinforced plastics as the main structure is to first spray a release agent on the molding surface of the mold, apply a gel coat, and then lay the blade shell, and then spread the release cloth on the blade...
