[0002] In the field of motor maintenance technology, the cleaning process of the motor cooling backpack is a necessary maintenance technology link. The motor cooling backpack is the main cooling device for cooling the motor. Once the motor is used online in an environment with a lot of dust and a long motor service life, it is bound to cause excessive dust and oil on the motor cooling backpack, causing the motor backpack cooling pipeline to be blocked. Finally, the cooling effect of the motor backpack is poor, resulting in excessive temperature rise of the motor, affecting the motor's use effect and online service life. In addition, the motor water-cooling backpack often leaks during online use. Once the motor water-cooling backpack leaks, the cooling water enters the motor stator, which can easily cause the motor winding to burn, seriously affecting the normal production order. Summary of the invention
