The utility model provides a flow velocity measuring device for hydraulic engineering, which comprises a mobile main body, a flow velocity measuring instrument, a vertical rod, a horizontal rod, a first electric push rod and an orientation adjusting mechanism, and the orientation adjusting mechanism comprises a sleeve, a rotating rod and a pushing plate. A first electric push rod descends the flow velocity measuring instrument into a river through a sleeve and a rotating rod, the situation that a worker is too close to the river is avoided, the personal safety of the worker is guaranteed, after the flow velocity measuring instrument descends into water, a push plate is also located underwater, and under the impact of water flow, the push plate rotates and drives the rotating rod to rotate; and finally, the pushing plate is parallel to the water flow direction, and the flow velocity measuring instrument faces the water flow direction, so that the flow velocity can be accurately measured, repeated adjustment of
