Description

Technical Field

[0001] The utility model relates to the technical field of generator filter cleaning, in particular to an ultrasonic generator filter cleaning device for a wind turbine generator set. Background Art

[0002] As a special type of power generation equipment, wind turbines generally work in very harsh environments and are mostly built in deserts, Gobi, plateaus and other areas where few people go. Due to the high concentration of wind turbine components, especially the cabin part, many components such as gearboxes, generators, main control cabinets and brakes are installed in a limited space. Dust and other particulate impurities have a great impact on the normal operation of the unit components. If they enter the electrical components, they may cause malfunctions or failures, seriously affecting the normal operation of the unit. Therefore, most wind turbines are equipped with cylindrical filters. However, during long-term use, the cylindrical filter needs to be cleaned. Most existing filter cleaning devices use high-pressure water flushing, which is not uniform and has poor cleaning effect. In addition, the cleaned filter needs to be left to stand for a long time before it can be dried and used again, resulting in a long cleaning time, which affects the power generation of the wind turbine.
