Novel full-automatic positioning buoy device and using method thereof

The invention provides a novel full-automatic positioning buoy device and a using method thereof, which relate to the field of water conservancy. The novel full-automatic positioning buoy device comprises a main buoy body, a circular plate is fixedly connected to the bottom of the main buoy body, two symmetrically-arranged side wing plates are fixedly connected to the outer surface of the main buoy body, a rudder-like empennage is fixedly connected to the outer surface of the main buoy body, and a position recording device is fixedly installed in the main buoy body. According to the novel full-automatic positioning buoy device and the using method thereof, the defects that a common buoy flow measuring method is inaccurate and depends on manpower are overcome, the characteristic that RTK can record the position in real time is utilized, the average flow velocity of the water surface within the range of 10 cm of the water surface is automatically measured in real time, and the accuracy of water flow surface flo
