This disclosure provides a water tank assembly, a cleaning device, and a cleaning system. The water tank assembly is installed on the cleaning device and includes a water tank and an overflow structure. The water tank includes a receiving cavity. The overflow structure includes an overflow pipe and a first overflow port and a second overflow port respectively disposed at both ends of the overflow pipe. The first overflow port and at least a portion of the overflow pipe are disposed within the receiving cavity, and the first overflow port is located at a predetermined overflow height within the receiving cavity. The second overflow port is positioned below the first overflow port and connects to the outside of the receiving cavity.

This application discloses a planetary gear assembly, a gearbox, and a wind turbine. The planetary gear assembly includes a planet carrier, a sun gear, and a stop. The planet carrier has an external spline and a mounting groove on its outer circumferential surface, with the external spline and mounting groove arranged axially along the planet carrier. The sun gear is fitted onto the outer circumferential surface of the planet carrier, and has an internal spline on its inner circumferential surface, which meshes with the external spline. The stop is detachably located at one end of the sun gear and has a protrusion protruding towards the axis of the planet carrier and beyond the inner circumferential surface of the sun gear. The protrusion is located within the mounting groove, which restricts the stop's axial movement along the planet carrier. The technical solution provided by this application allows for the design width of the internal spline to be unrestricted, fully utilizing available space to optimize the internal spline dimensions and improve load-bearing capacity.
