Zusammenfassung: | The invention provides a buoy flow measuring instrument suitable for a mountainous area drainage basin. The buoy flow measuring instrument comprises a semi-streamline body and a buoy shell with recovery power. A GPS distance measuring module, a single-chip microcomputer timing and flow velocity calculating module and a signal receiving and displaying module are arranged in an inner cavity of the flow measuring instrument, and the flow measuring instrument is further provided with a power source and a driving wheel which are used for recycling the flow measuring instrument. The output end of the power source is connected with the driving wheel; a propeller connected with the driven wheel is arranged at the tail part of the buoy shell; a plurality of magnetic attraction pieces are uniformly arranged at the peripheries of the transmission surfaces of the driving wheel and the driven wheel; the transmission surfaces of the driving wheel and the driven wheel are opposite, and when the driving wheel rotates, the ma |
