Underwater tail vane turning die and underwater navigation device containing the same

Abstract

The invention discloses an underwater stern rudder steering module, which comprises a steering mechanism fixedly connected with a rudder. The steering mechanism is arranged in a stern shell and comprises a rudder shaft which extends out of the stern shell and is fixedly connected with the rudder shaft; a sealed structure is arranged between the rudder shaft and the stern shell; the steering mechanism also comprises a motor, a screw rod connected with an output shaft of the motor, a screw nut arranged on the screw rod, a rotating seat fixedly connected with the screw nut, a vertically outward rotating part connected with the rotating seat, and a deflector rod inserted in the rotating part and fixedly connected with the rudder shaft; and the steering mechanism is fixedly connected to a fixed disk which is fixedly connected with the stern shell, and the fixed disk is fixedly connected with a control device of the steering mechanism. The invention also discloses an underwater running vehicle comprising the underwater stern rudder steering module. The underwater stern rudder steering module adopts a linkage mechanism and mechanical seal to realize stern rudder steering, and adopts the modularization design to ensure that the module has small volume and a compact structure which is easy to replace, dismount and mount; and the structure is simple and reliable, the driving torque is large, and the sealed structure has small frictional resistance and strong bearing capacity.

Description

technical field [0001] The invention relates to a tail rudder steering device, in particular to an underwater tail rudder steering module. The invention also relates to underwater vehicles. Background technique [0002] At present, in order to protect the marine environment and efficiently utilize marine resources, ocean detection is essential, and underwater vehicles are particularly important as the carrier of ocean detection sensors. The tail rudder steering device is used for attitude adjustment and heading change of the autonomous underwater vehicle. Most of the rudder steering mechanisms of current underwater vehicles adopt gear transmission, synchronous belt transmission, and hydraulic transmission. These mechanisms are generally large in size and mass, and are inconvenient to install and disassemble. The rudder shaft sealing structure of the current underwater vehicle also adopts a mechanical seal, but its entire structure is not easy to be quickly installed and di...
