Abstract The present invention discloses a UAV anti-sway device with variable capacity, which belongs to the technical field of agricultural aviation plant protection machinery equipment. It includes a number of vertically stacked tanks; each tank has a separate liquid inlet, a separate liquid outlet and a built-in liquid level sensor; each liquid outlet is connected to an electromagnetic directional valve through a pipeline and is led out by a main pipeline; the electromagnetic directional valve determines the connection and disconnection of the pipeline corresponding to each liquid outlet in accordance with the liquid level information detected by each liquid level sensor and controls the output of liquid from the main pipeline. Changes of liquid level in all liquid tanks are detected in real time through the adoption of the liquid sensor installed in each tank, and signals are fed back to the electromagnetic directional valve. These signals are then used by the electromagnetic directional valve for controlling the liquid discharge sequence of the liquid tanks, starting from the upper and lower ends to the middle so as to achieve the effect of stabilizing the center of gravity of the liquid tank. At the same time, the number of the tanks can be controlled in accordance with different operating conditions, thereby changing the capacity of the entire device, which can bring great convenience for plant protection operations with UAV.
