Embodiment 1

[0034] Such as Figure 1-3 As shown, in this embodiment, the universal joint includes a universal joint a14 and a universal joint b15 hinged with the universal joint a14, the propulsion motor 13 is arranged on the universal joint a14, and the universal joint b15 is hinged under the bracket 10 Middle; In this way, the propeller rotation motion transmission mechanism includes the propulsion motor 13, the propeller 12 and so on. The propeller 12 is connected with the propulsion motor 13 to form a tail thruster, which 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 slewing mechanism described below.

[0035] A yaw motor 16 and a rotary motor 17 are arranged on the static...

Embodiment 2

[0044] Such as Figure 4-7 As shown, the second embodiment has many similarities with the first embodiment. Wherein, the universal joint includes universal joint a14' and universal joint b15' hinged with the universal joint a14', the propulsion motor 13' is arranged on the universal joint a14', and the universal joint b15' is hinged on the support 10' The lower middle part; in this way, the propeller rotation motion transmission mechanism includes the propulsion motor 14, the propeller 17, the universal joint a14' and so on. The propulsion motor 13' is placed on the universal joint a14' and can transmit motion to the propeller through a pair of meshing gears.

[0045] The static platform is provided with a yaw motor 16' and a rotary motor 17', and the middle part of the static platform is provided with a first annular connecting piece 210' driven by the yaw motor 16' (specifically, a pair of meshing gears 113' and a gear 114 'to drive) and the second ring-shaped connecting p...

Abstract

The invention discloses an all deflection propeller vector boost mechanism and an underwater navigation vehicle provided with the same and belongs to the technical field of underwater navigation vehicles. The all deflection propeller vector boost mechanism comprises a support, wherein a disk serving as a static platform is arranged above the support, and a cardan joint serving as a dynamic platform is arranged below the support; a propeller and a boost motor are arranged on the dynamic platform and connected to form a tail thruster; a deflecting mechanism and a slewing mechanism are arranged between the dynamic platform and the static platform. Through motion synthesis of two relatively or completely independent motion chains, namely the deflecting mechanism and the slewing mechanism, the tail thruster can rotate in all directions at any deflecting angle. The all deflection propeller vector boost mechanism has the advantages of being convenient to install and control, good in low-speed steering performance and the like.

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...
