Integrated profile flow measuring instrument

The utility model relates to an integrated section flow measuring instrument, and belongs to the technical field of water conservancy river channel or channel flow velocity monitoring. According to the technical scheme, a plurality of floating bodies (2) are assembled together through a connecting frame (3) to form a multi-body ship (1), the tail of the multi-body ship (1) is connected with a tail vane floater (5) through a tail vane connecting rod (4), and a tail vane plate (6) is arranged below the tail vane floater (5); a two-dimensional stable steering engine (9) and a solar cell panel (13) are arranged on the multi-body ship, a sensor (10) is arranged below the two-dimensional stable steering engine (9), and the two-dimensional stable steering engine can adjust the sensor below the two-dimensional stable steering engine to keep the sensor vertically downward all the time; and the traction rope is matched on the multi-body ship. Manual charging is not needed, the sensor is kept to face the water flow dire
