Mine water inflow measuring device based on buoy method

The utility model provides a mine water inflow measuring device based on a buoy method, which comprises an electric control box, a flow measuring box and a buoy, a first photoelectric sensor, a second photoelectric sensor and a liquid level sensor are fixedly arranged on the flow measuring box, and a guide plate and a baffle plate are movably arranged on the flow measuring box. The control box is electrically connected with the first photoelectric sensor, the second photoelectric sensor and the liquid level sensor through wires, and the buoy is arranged in the flow measuring box and connected with the flow measuring box through a silk thread. The A/D conversion module can convert analog signals detected by the first photoelectric sensor, the second photoelectric sensor and the liquid level sensor into digital signals and upload the digital signals to the single-chip microcomputer control panel, then the single-chip microcomputer control panel calculates the flow according to the uploaded signals, and the calc
