Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle cleaning, and more specifically, to an unmanned aerial vehicle cleaning nozzle for wind power generation blades. Background Art

[0002] Wind turbine blades need to be cleaned regularly when in use. At present, when cleaning the blades, most of them are first suspended by their own control devices to prevent them from rotating during the cleaning process, and then the drone drives the nozzle to move and clean the blade surface. The blades are generally arranged with three equidistant intervals along the circumference, that is, the angle between two adjacent blades is 120 degrees. At present, there are generally several cleaning nozzles on the drone, so as to spray and clean various positions on one side of the blade at the same time, but most of the cleaning nozzles are generally matched with the vertical blades. When cleaning the inclined blades, the connection direction of the cleaning nozzle and the axis direction of the blade form a certain angle, resulting in the cleaning nozzle unable to cover the edge position of the blade, and the number of drone flights needs to be increased, and the cleaning efficiency is low; in addition, the cleaning nozzles are generally arranged with several intervals. When the interval between the cleaning nozzles is large, it is easy to cause the area between the two cleaning nozzles to be unable to spray. When the interval between the cleaning nozzles is small, there will be more overlapping areas in the coverage area, which will cause a waste of cleaning fluid and water. Utility Model Content
