Autonomous underwater vehicle (AUV) vector thrust device

Abstract

The invention discloses an autonomous underwater vehicle (AUV) vector thrust device. The AUV vector thrust device comprises a connecting frame, a pitch transmission mechanism and a steering transmission mechanism, wherein the pitch transmission mechanism comprises a pitch drive device, a pitch cylindrical gear transmission mechanism and a pitch screw transmission mechanism which are connected in sequence; and the steering mechanism comprises a bracket, and a steering drive device, a bevel gear wheel transmission mechanism, a steering cylindrical gear transmission mechanism, a steering screw transmission mechanism, an operating force delivery mechanism, a main thrust motor and a propeller which are connected in sequence. According to the AUV vector thrust device, control surfaces such as a rudder are eliminated by adopting vector thrust, so that an AUV has a compact overall structure, complete and smooth appearance and low resistance; compared with the control surfaces such as the rudder, the direction of thrust force is changed directly by vector thrust, and great operating force can be obtained even at a low speed, so that the AUV has high low-speed maneuverability; and compared with the same type of devices abroad, the vector thrust device provided by the invention has the advantages of larger steering engine swinging angle and larger operating torque.

Description

technical field [0001] The invention relates to an autonomous underwater vehicle propulsion device, which can manipulate an underwater robot to realize space movement and navigation attitude control. Background technique [0002] In order to better protect the marine environment and efficiently utilize marine resources, marine detection equipment is essential. As the carrier of ocean detection sensors, autonomous underwater vehicle (AUV) has become more and more important and has broad application prospects in ocean engineering. [0003] The power and control mode of the traditional underwater robot is: propeller propulsion device + pitch and steering steering gear. Due to the small force on the control rudder surface and the small control moment at low speed, the maneuverability of the vehicle with traditional propulsion device is poor at low speed. Moreover, due to the limitation of the area of ​​the rudder surface, the size of the rudder stern often exceeds the diameter...

Problems solved by technology

Due to the small force on the control rudder surface and the small control moment at low speed, the low-speed maneuverability of the vehicle using traditional propulsion devices is poor

Moreover, due to the limitation of the area of ​​the rudder surface, the size of the rudder stern often exceeds the diameter range of the vehicle body, and the operation and use are limited by the application occasions, and the larger rudder surface also greatly increases the resistance of the vehicle body
