Abstract

A parallel type underwater vectored thruster mainly comprises a machine frame, a turning machine and three movement branch chains for connecting the machine frame with the turning machine. Each movement branch chain is composed of a lower connection rod, a middle connection rod and an upper connection rod, wherein the lower connection rod and the machine frame are connected through a rotary pair or a sphere pair; the lower connection rod and the middle connection rod are connected through a rotary pair or a sphere pair; the middle connection rod and the upper connection rod are connected through a rotary pair; and the upper connection rod and the turning machine are connected through a rotary pair or a sphere pair. The three movement branch chains are connected with one another through three coupling connection rods and one center connection rod, one end of each coupling connection rod is fixedly connected with the middle connection rod of the corresponding movement branch chain, and the other end of each coupling connection rod is connected with the center connection rod through a rotary pair. Two-freedom-degree rotation of the turning machine relative to the machine frame can be achieved, the parallel type underwater vectored thruster has the advantages of being small in size, large in rigidity, high in precision, large in rotary working space and the like, and the parallel type underwater vectored thruster can be widely applied to ship thrust systems.

Description

technical field [0001] The invention relates to a vector thruster, in particular to a parallel underwater vector thruster. technical background [0002] At present, the vehicles used for underwater observation, investigation and development mainly include manned submersibles and unmanned submersibles. and mobility put forward higher requirements. In this context, the submersible using the traditional fin-rudder control method has been unable to meet the task requirements to a certain extent, especially when the maneuverability of the rudder is significantly weakened when moving at low speed. In order to improve the flexibility of the submersible, developing a new type of submersible with a vector thruster is one of the effective solutions. [0003] Vector propulsion is also called thrust steering technology, which means that the propulsion system of a space moving object can not only provide forward thrust, but also simultaneously or separately provide thrust and torque in...
