The invention relates to the technical field of navigation cabins of unmanned underwater vehicles, in particular to a navigation cabin device for an unmanned underwater vehicle. The device comprises an upper end cover, a main shell, a lower end cover, an inertial navigation mounting ring and an inertial navigation device, wherein the main shell is fixedly connected with the upper end of the upper end cover; the lower end cover is fixedly connected with the lower end of the upper end cover; the inertial navigation mounting ring is fixedly connected with the inner side of the main shell; the inertial navigation device is fixed at the lower end of the inertial navigation mounting ring. According to the navigation cabin device of the unmanned underwater vehicle, through reasonable structural design, two types of Doppler log, a depth gauge and an inertial navigation device can be integrated in one cabin, and a high-precision navigation positioning function under deep and shallow water conditions is realized through cooperative work of the two types of Doppler log, the depth gauge and the inertial navigation device. Calibration and debugging work can be carried out in advance without depending on a platform. A watertight cable can be connected through a watertight connector on the side face of the main shell to supply power to the navigation cabin, and a corresponding input and output signal cable is connected to carry out underwater debugging work.
本发明涉及水下无人潜航器的导航舱技术领域,特别是涉及一种用于水下无人潜航器的导航舱装置。本发明包括上端盖、主壳体、下端盖、惯导安装环、惯性导航装置,主壳体与所述上端盖的上端固定连接;下端盖与所述上端盖的下端固定连接;惯导安装环与所述主壳体的内侧固定连接;惯性导航装置固定于所述惯导安装环的下端。本发明的水下无人潜航器的导航舱装置通过合理的结构设计,可以在一舱内集成两型多普勒计程仪、深度计和惯性导航装置,其协同工作实现深浅水条件下的高精度导航定位功能。本发明可不依赖于平台提前开展标定调试工作。且可通过主壳体侧面水密接插件接入水密电缆为导航舱供电,并接入相应的输入输出信号电缆,进行水下调试工作。
