Embodiment Construction
[0044] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0045] At present, with the advancement of science and technology, wind power generation is becoming more and more common. In wind power generation, the main shaft of the fan in the fan plays a key role. After long-term use, the main shaft of the fan will suffer from fatigue peeling, wear, scratches, indentation, corrosion and fracture. Therefore, the main shaft of the fan needs to be inspected regularly.

The invention discloses a detection method and device which are used for solving the problems that time and labor are consumed and the cost is high during disassembling when nondestructive detection is performed on a fan spindle in the prior art. In an embodiment, firstly, a detected spindle is detected through ultrasonic waves, a detection ultrasonic energy spectrum is obtained, pulse time domaindata corresponding to the energy concentrated position in the detection ultrasonic energy spectrum are compared with corresponding preset spindle information and pulse time domain data for detectionof a standard shaft, if the comparison result is in a preset range, the detected spindle passes detection, and otherwise, the detected spindle is determined to have defects. The detected spindle is detected through ultrasonic waves, and whether the detected shaft has defects is determined according to the comparison result of the detection result and the corresponding preset spindle information and pulse time domain data of the standard shaft, so that when nondestructive detection is performed on the fan spindle, the fan spindle is not required to be disassembled, the detection cost can be reduced, and the detection efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of wireless communication, in particular to a detection method and device. Background technique [0002] Wind energy is a green energy with the characteristics of high efficiency, cleanness, safety and sustainability. Its research and development have attracted the attention of various countries. Wind power generation is the main way to utilize wind energy, and the main shaft bearing of the wind turbine in the wind turbine is one of the key components. It mainly supports the quality of the blades, hubs and their auxiliary components and is located at a high position. The occurrence of its failure will directly cause the overall wind turbine damaged or even collapsed. Among them, the main failures of the fan shaft are fatigue spalling, wear, abrasion, indentation, corrosion and fracture. Therefore, it is very important for the non-destructive testing of the fan shaft. [0003] The traditional detection met...
