Abstract

The invention discloses a single-mode surface-mounted piezoelectric-driven swing fin device and a working method thereof. The single-mode surface-mounted piezoelectric-driven swing fin device comprises a support guide rail, a piezoelectric transducer, an elastic thin plate, a first limiting plate, a second limiting plate and a swing fin. According to the invention, the elastic connecting thin plate, the piezoelectric transducer and the working track are matched, and the patch type piezoelectric transducer acts in a longitudinal vibration single mode and is in inclined contact with the guide rail under the bending pressure action of the elastic thin plate, so that the swinging fin can be driven to perform automatic reciprocating swinging and automatic reversing on the working track. The piezoelectric excitation and friction driving structure can be opened to seawater, strict sealing is not needed, and the restriction of deep sea high water pressure on a driving system is relieved.

Description

technical field [0001] The invention relates to the fields of friction driving and piezoelectric transducers, in particular to a single-mode patch piezoelectric driving swing fin device and a working method thereof. Background technique [0002] Whether it is marine health monitoring, marine resource development, or the maintenance of marine rights and interests, the acquisition of marine information is the most basic work. In recent years, due to the advancement of computer-aided design, advanced manufacturing technology, sensors and other technologies, the underwater mobile unmanned and cableless detection equipment represented by autonomous underwater vehicles (AUV) is moving towards the direction of miniaturization and miniaturization. For development, it is necessary to carry underwater propellers with compact structure, small mass and safe operation. However, traditional propellers with electromagnetic motors and propellers are difficult to adapt to the deep-sea envir...
