Technical Field

[0001] This utility model relates to the field of magnetic particle flaw detector technology, specifically a magnetic particle flaw detector for the main shaft of a wind turbine generator. Background Technology

[0002] A magnetic particle flaw detector is a non-destructive testing device used to detect surface and near-surface defects in ferromagnetic materials. It uses the leakage magnetic field at the defect to attract magnetic particles by magnetizing the ferromagnetic material, thereby revealing the location, shape, and size of the defect.

[0003] Magnetic particle inspection machines are usually manually adjusted during inspection to achieve a thorough inspection of the items. However, due to the large size of the wind turbine main shaft, it is difficult to adjust it manually, which makes it inconvenient to perform a thorough inspection of the wind turbine main shaft and may lead to omissions. Therefore, there is a need to provide a magnetic particle inspection machine for wind turbine main shafts. Utility Model Content

Then, the main shaft is fixed by the internal clamping plate and spring. At the same time, the annular plate can move in the annular groove. Then, the drive motor drives the threaded rod to rotate, thereby adjusting the fixing plate to the appropriate position. Then, the other end of the main shaft is clamped into the inside of the rotating shaft. When the flaw detection component at the top inspects the wind turbine main shaft, the rotating motor can drive the main shaft to rotate, which facilitates a thorough inspection of the main shaft and avoids missing any damaged areas, thus improving the practicality of the device.
