[0041] The present invention discloses an adjustable underwater acoustic test deployment device. The retractable movable component in the base 1 of the support mechanism can be conveniently moved and fixed on a ship or on shore, and the position can be conveniently adjusted. The support component is arranged on the base 1, and is used to support the test mechanism, so as to conveniently control the lifting and lowering of the test mechanism under the water surface. The sealing tube 17 can be watertight, and is used to install various electrical components. A transmitting transducer 19 is suspended at the bottom of the sealing tube 17 through a conductive first conductive rope 18, and is used to transmit and receive sound waves at different water depths to complete the underwater acoustic test. The positioning mechanism is arranged at the top of the transmitting transducer 19, and is used to position the transmitting transducer 19 on the sealing tube 17, and can conveniently position the water depth position of the transmitting transducer 19. At the same time, the initial positioning of the transmitting transducer 19 can be prompted, so as to facilitate the subsequent water immersion depth distance of the transmitting transducer 19, and the positioning is more accurate, thereby improving the efficiency of the underwater acoustic test.
