The invention relates to an underwater vehicle and a sonar transducer protection device thereof, the underwater vehicle comprises the sonar transducer protection device, and the sonar transducer protection device comprises a mounting base, a transducer mounting seat, a protection plate, a transducer driving mechanism and a protection plate driving mechanism; the transducer mounting seat is provided with an outward extending position and an inward retracting position in the reciprocating motion stroke, the transducer is enabled to extend outwards from the retracting opening of the underwater vehicle shell when the transducer mounting seat is in the outward extending position, and the transducer is enabled to retract inwards from the retracting opening when the transducer mounting seat is in the inward retracting position; the protection plate is provided with a sealing position and an avoiding position in the reciprocating motion stroke, and the protection plate is used for moving to the sealing position to seal and cover the retracting and releasing opening of the underwater vehicle shell after the transducer retracts inwards and avoiding the retracting and releasing opening when the protection plate is located in the avoiding position so that the transducer can extend outwards; the energy converter is retracted into the underwater vehicle shell, and the protection plate covers the retracting opening, so that the energy converter is prevented from being damaged due to contact and collision between the energy converter and the recovery platform.
本发明涉及一种水下航行器及其声呐换能器防护装置,水下航行器包括声呐换能器防护装置,声呐换能器防护装置包括安装基座、换能器安装座、防护板、换能器驱动机构、防护板驱动机构;换能器安装座在其往复移动行程上具有外伸位和内缩位,在外伸位时使换能器从水下航行器壳体的收放口向外伸出,在内缩位时使换能器从收放口向内缩回;防护板在其往复移动行程上具有封盖位和让开位,防护板用于在换能器向内缩回后移动到封盖位以封盖水下航行器壳体的收放口,在处于让开位时让开收放口以供换能器向外伸出;将换能器收回到水下航行器壳体内,并将防护板封盖在收放口处,避免换能器与回收平台发生接触碰撞而导致换能器损坏。
