Abstract

The invention discloses an automatic lifting rotating scanning device of a hydrophone. The automatic lifting rotating scanning device of the hydrophone comprises a rack, the rack is provided with a landing gear, a moving frame, a moving platform, a screw rod, a lifting table and a rotating spindle, the landing gear performs Z-direction lifting movement along the rack, the moving frame performs X-direction translational motion on the landing gear, the moving platform performs Y-direction translational motion on the moving frame, the screw rod is vertically installed on the moving platform, the lifting table is driven by the screw rod to perform lifting movement, the rotating spindle is vertically installed on the lifting table, the rotating spindle and the lifting table are rotatably matched with each other and axially fixed, and the bottom of the rotating spindle is used for suspending the hydrophone or a detected sample which is matched with the hydrophone. A driving mode of the screw rod and the rotating spindle includes that a screw rod driving step motor is mounted on the moving platform, the screw rod driving step motor drives the screw rod to rotate through a screw rod synchronous belt, a rotating sleeve and a step motor are arranged on the moving platform, the step motor drives the rotating sleeve to rotate, the step motor drives the rotating sleeve through a driving belt, and the rotating spindle penetrates the rotating sleeve and is circumferentially positioned and is in axial sliding fit with the rotating sleeve.

Description

technical field [0001] The invention relates to a hydrophone testing device, in particular to a hydrophone automatic lifting and rotating scanning device. Background technique [0002] Hydrophone, commonly known as sonar, is an electronic device that uses the propagation characteristics of sound waves underwater to complete underwater detection and communication tasks through electro-acoustic conversion and information processing. A hydrophone is an electronic device that uses underwater sound waves to detect, locate and communicate underwater targets. It is the most widely used and most important device in underwater acoustics. [0003] With the continuous development of hydrophone technology, the working method of hydrophone has also undergone rapid changes. The concept of hydrophone array is the latest concept in this field. As the name implies, the hydrophone array is to realize the all-round monitoring of the surrounding environment or the tracking and monitoring of a...
