Embodiment 1

[0027] Embodiment one: if Figure 1-3 As shown, the three-dimensional vector propulsion device for the submersible of the present embodiment includes a prime mover 1, a reduction transmission mechanism, four sets of thrust mechanisms, a column base (gear box) 14, the gear box 14 is a square column, and the cross section is back-shaped. The inner ring is called the inner wall, and the outer ring is called the outer wall. The four groups of thrust mechanisms have the same structure and are symmetrically arranged around the outer wall of the gear box 14 . Each set of thrust mechanisms includes a rotating disk main gear (transmission bevel gear) 6, a rotating disk main shaft 7, a thrust direction controller 8, a transmission shaft 9, a central gear 10, a bridge gear 11, a paddle gear 12, a rotating disk 13, and a paddle Blade 16, paddle shaft 17, bridge gear shaft 18. The reduction transmission mechanism includes a shaft coupling 2, a driving gear 3, a planetary gear 4, an inner...

Embodiment 2

[0032] Embodiment two: see Figure 8 , the prime mover 1 of this embodiment is linked with the driving gear 3 in the gearbox 14 through the coupling 2, the driving gear 3 is meshed with the driven gear 4, and the driven gear 4 is linked with the bevel gear 5, so that the driven gear 4 can drive the bevel gear 5 to rotate; and the bevel gear 5 is meshed with the four rotating disk main gears 6 around, so that the bevel gear 5 can simultaneously drive the four rotating disk main gears 6 to rotate. The other content of this embodiment is the same as that of Embodiment 1, please refer to Embodiment 1.

Embodiment 3

[0033] Embodiment three: see Figure 9 , 10 , the present embodiment adopts a single prime mover drive mode, that is, each prime mover drives a group of thrust mechanisms. The prime mover 1 adopts a direct-drive motor, which is installed in the gear box 14, and its output shaft directly drives the rotating disk main shaft 7, thereby eliminating the reduction transmission mechanism and further simplifying the structure of the propulsion device. Since the rotational speed of each thruster rotating disk 13 can be adjusted arbitrarily, this technical solution can make the change of the thrust magnitude and direction of the three-dimensional vector propulsion device more flexible. For other content of this embodiment, refer to Embodiment 1.

Abstract

The invention relates to a three-dimensional vector thrusting device for a submersible. The three-dimensional vector thrusting device for the submersible comprises a prime motor, a base, and at least three groups of thrusting mechanisms which have the same structure and are uniformly distributed on the periphery of the base, wherein a main shaft is driven by the prime motor, and is in rotational fit with the base; the outer end of the main shaft penetrates the outer wall of the base and is fixedly connected with the inner bottom surface of a rotating disc; the main shaft is hollow; a transmission shaft is inserted into the main shaft in an axial direction; the inner end of the transmission shaft extends out of the main shaft and the inner wall of the base and is connected with a thrust direction controller; the other end of the transmission shaft penetrates the inner bottom of the rotating disc, is linked with a center gear and is arranged on the outer bottom of the rotating disc in a rotatable way; the center gear is positioned inside the rotating disc; a plurality of paddle shafts are in rotational fit inside the rotating disc; the paddle shafts penetrate and are linked with a paddle gear; the paddle gear is connected with the center gear through a transmission component; the paddle shafts extend out of the outer bottom of the rotating disc and are fixedly connected with one end of each of paddles; and when the rotating disc rotates a circle, the paddles rotate half a circle around the axes of the paddles. The size and direction of thrust can be arbitrarily changed within a three-dimensional space.

Description

technical field [0001] The invention belongs to the technical field of propulsion and manipulation of submersibles, in particular to a three-dimensional vector propulsion device for submersibles which converts the effective power emitted by the main engine into the thrust required for the submersible to advance and turn. Background technique [0002] At present, the propulsion control devices related to ships mainly include: propeller-rudder system, full-turn propeller (rudder oar), water jet propeller, straight wing propeller, etc. However, the propulsion and manipulation forces of the above-mentioned devices are limited to two-dimensional planes. For equipment such as submarines, torpedoes, submersibles, robots, and underwater detection, it is necessary to install multiple sets of the above-mentioned propulsion devices to meet the needs of underwater three-dimensional maneuvering. Therefore, the existing propulsion device complicates the structure of the submersible and i...
