Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of unmanned aerial vehicle high-pressure water spraying equipment, in particular to an unmanned aerial vehicle airborne high-pressure water spraying device. Background Art
[0002] UAVs are unmanned aircraft controlled by radio remote control equipment and self-contained program control devices. UAVs can be divided into military and civilian applications according to their application areas. At present, agricultural UAVs are often used to spray water and pesticides on large areas of crops. When spraying water, due to the large spraying area and the limited load capacity of the UAV, it is generally necessary to use a longer water pipe to supply water on the ground. This method mostly involves binding ordinary water pipes or water guns to the frame of the UAV. When the angle needs to be adjusted, it is generally necessary to operate the UAV for adjustment. When spraying water on a large area of the ground, the efficiency is low and it has certain limitations. To this end, we propose a UAV-mounted high-pressure water spraying device.
