Abstract

This utility model discloses an acoustic detection device for waterway surveying, belonging to the field of waterway surveying. It includes a mounting plate with a cutting assembly at its lower end. The cutting assembly includes a rotating base installed inside the mounting plate, a rotating roller rotatably connected inside the rotating base, a cutting blade fixedly sleeved on the outer wall of the rotating roller, and a toothed sleeve fixedly sleeved on the outer wall of the rotating roller. Through the coordinated use of these devices, the stability and efficiency of waterway detection are improved. Driven by a motor, in conjunction with the toothed sleeve, active gear, reciprocating screw, rotating roller, and cutting blade, the component rotates, allowing the cutting blade to quickly cut away roots and aquatic plants. Combined with the longitudinal displacement of the cutting blade holder, debris is quickly cut off and pushed away from the outer wall of the protective cover, preventing debris from adhering to the outer wall of the detector along with the water flow, thereby improving the detector's detection environment and increasing the accuracy of the detection data.
