A modular adjustable fixing device for an underwater acoustic transducer array includes a main support rod, a central structural component, a transducer fixing ring, and a sliding connector. One end of the main support rod is fixedly connected to the interior of the central structural component through three sets of square holes. The other end extends to form a Y-shaped array frame. The extended end of the main support rod is used to fix the transducer fixing ring, which is fixed to the main support rod by the sliding connector and suspended from the rear side of the central structural component. The sliding connector is slidably fitted onto the main support rod and positioned by fasteners, with its end connected to the transducer fixing ring. The central transducer fixing ring is fixed to the top of the central structural component. This invention allows for flexible adjustment of the baseline length of the underwater acoustic transducer array by adjusting the position of the sliding connector, meeting the acoustic testing requirements of different array models. Furthermore, its modular design facilitates easy disassembly and is suitable for stable fixing of transducer arrays in complex aquatic environments.
