Navigation cabin device for unmanned underwater vehicle

Abstract

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.
