本发明公开了一种用于防止农药喷雾漂移的矢量控制装置,包括检测装置、喷雾装置和控制装置;所述检测装置用于检测植保无人机飞行时的风向和风速;所述喷雾装置包括支架、喷雾机构以及用于调节喷雾机构的喷雾角度的喷雾调节机构;所述喷雾机构包括球形全向喷头和供液模块;所述喷雾调节机构包括设置在所述球形全向喷头上的全向摆动致偏环以及用于驱动全向摆动致偏环竖向摆动的竖向摆动机构;所述控制装置根据所述检测装置检测出的植保无人机飞行时的风力和风向,控制多组竖向摆动机构工作,以此调节所述球形全向喷头的喷雾角度。本发明的矢量控制装置可以减小与自然风和植保无人机旋翼产生的下洗风场之间的迎风角,从而减少农药漂移。
The invention discloses a vector control device for preventing pesticide spraying drift. The vector control device comprises a detection device, a spraying device and a control device, the detection device is used for detecting the wind direction and the wind speed when the plant protection unmanned aerial vehicle flies; the spraying device comprises a support, a spraying mechanism and a spraying adjusting mechanism used for adjusting the spraying angle of the spraying mechanism. The spraying mechanism comprises a spherical omni-directional nozzle and a liquid supply module; the spray adjusting mechanism comprises an omni-directional swing deflection ring arranged on the spherical omni-directional spray head and a vertical swing mechanism used for driving the omni-directional swing deflection ring to vertically swing; the control device controls the multiple sets of vertical swing mechanisms to work according to the wind power and the wind direction detected by the detection device when the plant protection unmanned aerial vehicle flies, so that the spraying angle of the spherical omni-directional spray head is adjusted. According to the vector control device, the windward angle between natural wind and a downwash wind field generated by the rotor wing of the plant protection unmanned aerial vehicle can be reduced, so that pesticide drifting is reduced.
