Connecting apparatus of ultra short baseline transducer

The invention relates to a connecting apparatus of an ultra short baseline transducer. The connecting apparatus comprises a transducer and a transducer shaft; a transducer shaft sleeve is arranged at the upper end of the transducer; and the transducer and the transducer shaft sleeve are connected by a flange plate. An adjusting ring is arranged at the upper end of the transducer shaft sleeve; adjusting holes are formed in the adjusting ring; the adjusting ring passes through the adjusting holes and is connected with the transducer shaft sleeve detachably by first bolts, wherein the first bots can move in the adjusting holes. The combined body of the transducer and the transducer shaft sleeve can rotate relative to the adjusting ring. The lower part of the transducer shaft extends into the adjusting ring downwardly; the adjusting ring and the lower part of the transducer shaft are connected by a plurality of second bolts; and the adjusting ring is connected with the transducer detachably by a positioning pin. Compared with the prior art, the connecting apparatus can be adjusted conveniently; the installation precision can be improved; the operation becomes convenient; and the time and effort are saved.
