An automatic hydrological buoy throw-in device belongs to the technical field of hydrologic automatic detection and is characterized in that the automatic hydrological buoy throw-in device is an automatic detection device which throws a buoy in a remote control manner; can throw the buoy at multiple positions and the same position for multiple times at any climate, and guarantees the hydrological survey accuracy. The device is composed of a transmission execution part, a drive part and a control part. The movement is that electromagnets 2 are electrified, the electromagnets 2 perform the movement of pushing to push ratchet wheels 14 to rotate, cylindrical cams 1 and sleeve shafts 12 rotate simultaneously, hooks 9 rotate to a drooping state by surrounding pin rolls 6 under the gravity action of the hooks 9 and the buoy 18, and thus the buoy 18 is thrown; the movements are repeated to throw eight buoys 18 in sequence; the electromagnets 2 are intermittently controlled to be electrified, at the time, cam rollers 15 enter the pressing curved segments of grooves of the cylindrical cams 1, the sleeve shafts 12 are pressed, and the hooks 9 rotate to the horizontal state; the electromagnets 2 are electrified again, the cam rollers 15 enter the lifting curved segments of the grooves of the cylindrical cams 1, and the hooks 9 return to the initial positions.
