Embodiment 1

[0034] Such as Figure 1-3 As shown, in this embodiment, the universal joint includes a universal joint a 14 and a universal joint b 15 hinged with the universal joint a 14, the propulsion motor 13 is arranged on the universal joint a 14, and the universal joint b 15 is hinged In the lower middle part of the bracket 10; thus, the propeller rotation motion transmission mechanism includes a propulsion motor 13, a propeller 12, and the like. The propeller 12 is connected with the propulsion motor 13 to form a tail propeller, and is fixedly connected to the external universal joint a14. The propulsion motor 13 directly transmits the rotational motion to the propeller 12 to make it generate rotational motion to provide propulsion for the underwater robot. The tail thruster uses the universal joint a14 as a platform, and realizes all-round rotation in space through the yaw mechanism and the slewing mechanism described below.

Abstract

The invention discloses a fully deflected propeller vector propulsion mechanism and an underwater vehicle with the mechanism, belonging to the technical field of underwater vehicles. The full-deflection propeller vector propulsion mechanism includes a support, a disk used as a static platform is arranged above the support, and a universal joint used as a moving platform is arranged below the support, wherein: the moving platform is provided with a propeller and the propulsion motor, the propeller and the propulsion motor are connected to form a tail thruster; a yaw mechanism and a slewing mechanism are arranged between the moving platform and the static platform. In the present invention, through the kinematic synthesis of two relatively independent or completely independent kinematic chains of the yaw mechanism and the slewing mechanism, the tail thruster can realize omni-directional rotation at any yaw angle. It has the characteristics of convenient installation, convenient control, and good low-speed steering performance.

Description

technical field [0001] The invention relates to the technical field of underwater vehicles, in particular to a fully deflected propeller vector propulsion mechanism and an underwater vehicle with the mechanism. Background technique [0002] The development of underwater robots in our country is still in its infancy. Although some products have been developed, there is still a long distance from practical application. On the other hand, the need for underwater robots in my country's ocean development, offshore oil extraction and military fields is increasing and becoming increasingly urgent. [0003] At present, most underwater robots use propeller propellers as propulsion devices. A single-dimensional propeller propeller can only produce propulsive force with variable magnitude in one direction, and when the robot needs to perform multi-direction oriented manipulation movements, such as pitch and yaw, it is necessary to install multiple single-dimensional propeller propell...
