Description

Technical Field

[0001] The utility model relates to the technical field of motor stator cleaning, in particular to a dust removal device for cleaning the stator of a hydropower plant generator. Background Art

[0002] With the rapid development of modern industrialization, hydropower, as a clean and renewable energy form, has become increasingly prominent in the global energy structure. As the main production unit of hydropower energy, the operating efficiency and stability of hydropower plants are directly related to the supply of energy and economic benefits. However, during the long-term operation of hydropower plants, dust is easily accumulated inside the generator stator. This dust not only affects the heat dissipation effect of the generator, but also may damage the insulation performance of the generator, thus seriously affecting the normal operation and life of the generator. Therefore, it is necessary to use a dust removal device for cleaning the stator of the hydropower plant generator to clean the outer surface of the motor stator.

[0003] The traditional way of cleaning the generator stator mainly relies on manual cleaning, however, this cleaning method has many disadvantages. First, manual cleaning is inefficient and takes a long time to clean, which cannot meet the needs of efficient operation of large hydropower plants. Second, manual cleaning is difficult to completely remove the stubborn dust inside the stator, especially in some hard-to-reach corners and gaps, where dust easily accumulates and forms dead corners. In addition, metal debris or dust on the outer surface of the motor stator may fall into the wind tunnel during cleaning and cannot be collected manually.

[0004] In summary, it is necessary to develop a dust removal device for cleaning the stator of a hydropower plant generator to solve the above problems. Utility Model Content
