Spraying arm assembly and cleaning device

The invention relates to the field of electrical equipment, and discloses a gushing arm assembly and a cleaning device, the water spraying direction of a second gushing arm spraying hole in the gushing arm assembly always faces the required direction, the relative angle between the gushing arm spraying water flow and a to-be-cleaned part is not changed, and the cleaning effect is remarkably enhanced. The spraying arm assembly is applied to the cleaning device. The spraying arm assembly comprises a spraying arm base, a first spraying arm, a second spraying arm and a transmission structure. The first gushing arm is rotatably arranged on the gushing arm seat; the second gushing arm is arranged at one end of the first gushing arm and provided with a plurality of second gushing arm spraying holes, the first gushing arm drives the second gushing arm to revolve around a rotating shaft of the first gushing arm, and the water spraying direction of the second gushing arm spraying holes is always unchanged; the transmis
