Abstract

The invention relates to a pressure-resistant type underwater sound cylindrical transducer array. The pressure-resistant type underwater sound cylindrical transducer array comprises an upper cover housing, a cylindrical part and a lower cover housing, the upper cover housing and the lower cover housing are respectively and fixedly connected to the upper end and the lower end of the cylindrical part, the cylindrical part comprises an aluminum inner cylinder, an array rack, a rubber outer wall and a plurality of transducer array elements, the array rack is an annular cylinder, the array rack isprovided with a plurality of installing holes matched with the transducer array elements, the plurality of transducer array elements are respectively arranged in the installing holes, and the array rack is arranged between the aluminum inner cylinder and the rubber outer wall in a sealed manner. According to the technical scheme, the plurality of transducer array elements form a cylindrical transducer array, the cylindrical transducer array has high pressure resistance and small fluctuation of sound pressure in a horizontal wave beam, and the technical problem that the detection effect of a cylindrical sonar is influenced due to poor pressure resistance and large fluctuation of the directivity of the horizontal wave beam of the conventional cylindrical array transducer is solved.

Description

technical field [0001] The invention relates to an underwater acoustic transducer array, in particular to a pressure-resistant underwater acoustic cylindrical transducer array. Background technique [0002] Sonar detection is the use of underwater sound waves to detect underwater targets. It is widely used in torpedo guidance, mine fuzes, fish detection, offshore oil exploration, ship navigation, underwater operations, hydrographic surveys, and surveys of submarine geology and landforms. Sonar is composed of a transmitter, a transducer, a receiver, a display, a timer, a controller and other main components. The transmitter produces an electrical signal and passes through the transducer to convert the electrical signal into a sound signal and transmit it to the water. When the sound signal is transmitted in the water If you encounter targets such as submarines, mines, fish schools, etc., they will be reflected back. The reflected sound waves are received by the transducer and...
