Description

Fan blade root crack detection device Technical Field The utility model belongs to the technical field of fan detection equipment, and particularly relates to a device for detecting cracks at the root of a fan blade. Background The root of the wind driven generator is used as a key bearing part of a connecting hub, is subjected to alternating load, environmental corrosion and extreme climate impact for a long time, and is easy to generate fatigue cracks between composite material layers or around bolt holes, so that periodic cleaning and detection are core links for guaranteeing safe operation of the wind driven generator, especially in the daily monitoring process, if cracks generated at the root of a blade can be found in time, the occurrence of accidents can be avoided to a great extent, however, the existing blade root detection flaw detection device only detects the blade through a flaw detector in the working process by adsorbing the crack on the blade of the wind driven generator, the outdoor wind driven generator blade is subjected to wind blowing and sun-curing all the year round, more bird droppings and stains are attached to the blade, the flaw detection effect can be influenced in the flaw detection process, and the tiny cracks are not easy to find to have potential safety hazards. Therefore, it is desirable to design a device that can clean blade stains and impurities when detecting a crack in a fan blade. Disclosure of utility model The utility model aims at the technical problem, and provides a device capable of cleaning blade stains and impurities during crack detection of a fan blade so as to solve the problem that the existing detection flaw detection device cannot remove the impurities on the surface of the blade.
