The invention discloses a combined mechanism for measuring depth of a longitudinal flow bow ship. The combined mechanism belongs to an auxiliary mechanism for measuring depth of the ship. The combined mechanism comprises a lifting mechanism and an air deflector, wherein the lifting mechanism comprises a movable rod. The movable rod is arranged in a cylinder. Furthermore the starting end of the movable rod is connected with the output end of a hydraulic cylinder through a connecting board. One end, which corresponds with the starting end of the movable rod, of the cylinder is mounted on the connecting board through a transition shaft. The end of the movable rod is also provided with a transducer. The air deflector is provided with a through hole and an arc-shaped contour. The end of the cylinder is communicated with the through hole on the air deflector. Through mounting the transducer on the end of the movable rod, and driving the transducer to be lifted through the hydraulic cylinder, controllability for the underwater real-time position of the transducer is improved. Furthermore the flow field in front of the transducer of a depth finder can be improved through the arc-shaped contour on the air deflector, thereby reducing an effect of objects such as a vortex to the ultrasonic wave, so that the influence by the water current at the ship bottom can be prevented on any condition, thereby ensuring accurate and reliable data of the depth finder.
