[0002] The rotating mechanism of an underwater unmanned vehicle (UAV) is one of the core components enabling its flexible movement and precise operation. Its role extends to multiple dimensions, including navigation control, mission execution, and environmental adaptation, directly impacting the vehicle's functionality and operational efficiency. It is not only a component for motion control but also a crucial guarantee for adapting to complex underwater environments and completing diverse tasks. From basic navigation to high-precision operational control, the performance of the rotating mechanism directly determines the UAV's operational capabilities and reliability, making it a key area requiring optimization in underwater equipment design.

Furthermore, due to the high integration rate of underwater unmanned vehicles, their rotating mechanisms are difficult to assemble, affecting the disassembly and assembly of other equipment. This results in increased product weight, difficulty in repairing and replacing equipment parts, and safety hazards such as easy interference between internal components and high failure rate.

[0004] Therefore, there is an urgent need to propose a rotating mechanism for use in underwater unmanned vehicles to solve the problems of complex internal structure, poor maintainability, high cost, and interference with other structures during rotation in existing technologies.

[0028] The terms "set up," "connect," and "fix" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] The preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0031] Example: A rotating mechanism applied to an underwater unmanned vehicle according to this example includes a support base 1, a rotating shaft 2, an upper bearing on the rotating shaft 5, a rotating motor 7, a driving gear 9, a driven gear 10, a gear ring 11, a rotating shaft 12, a platform 13, and a lower bearing on the rotating shaft 15.

[0032] The base plate of the support seat 1 is fixedly connected to the interior of the underwater unmanned vehicle. The bottom of the rotating shaft 2 is installed inside the cylinder 14 of the support seat 1. The upper and lower ends of the rotating shaft 2 are installed with the cylinder 14 through the upper bearing 5 and the lower bearing 15 of the rotating shaft.

[0033] The drive shaft of the rotary motor 7 is fixed in the bottom blind hole of the rotary shaft 2 by a flat key 8 to fix the rotary motor 7, thereby driving the device to be rotated to rotate and realizing the rotation function of the mounted device. The drive gear 9 is fixed to the top of the rotary shaft 2 by a flat key 8. The drive gear 9 meshes with the driven gear 10. The rotating shaft 12 is fixed on the platform 13. The driven gear 10 is set on the rotating shaft 12 and meshes with the gear ring 11. The platform 13 is installed on the rotary shaft 2 and connected to the gear ring 11.

[0034] More specifically: the support base 1 also includes stiffening plates;

[0035] The cylinder 14 is welded to the base plate, and the stiffening plate is welded to the outside of the cylinder 14;

[0036] Based on the dimensions of the steering mechanism and the interface location of the underwater unmanned vehicle, a corresponding support base 1 is designed.

[0037] More specifically: the cylinder 14 is provided with drainage holes to ensure the underwater application of the rotating mechanism.

[0038] More specifically: a shaft elastic retaining ring 4 is provided on the upper side of the upper bearing 5 of the rotating shaft and the lower side of the lower bearing 15 of the rotating shaft;

[0039] A bearing retaining ring 3 is provided on the lower side of the rotating shaft lower bearing 15, and a hole elastic retaining ring 6 is connected below the bearing retaining ring 3. The upper end of the hole elastic retaining ring 6 abuts against the lower end face of the bearing retaining ring 3.

[0040] More specifically: the specifications of the elastic retaining ring 4 for the shaft are GB / T 894.1, which is a national standard product that is readily available in the market;

[0041] The specifications of the elastic retaining ring 6 for the hole are GB / T 893.1, which is a national standard product that is readily available in the market.

[0042] More specifically: the specifications of the upper bearing 5 and the lower bearing 15 of the rotating shaft are GB / T 276, which are national standard products that are readily available in the market.

[0043] More specifically: the specifications of the flat key 8 are GB / T 1096, which is a national standard product that is readily available in the market.

[0044] More specifically: the upper bearing 5, the lower bearing 15, the bearing retaining ring 3, and the rotating shaft 2 are coaxial with the cylinder 14.

[0045] More specifically: the upper shaft is limited by the elastic retaining ring 4 to the rotating shaft bearing 5 and the rotating shaft 2, for axial positioning of the rotating shaft 2, and the rotating shaft bearing 5 for radial positioning of the rotating shaft 2 and for controlling the rotation of the rotating shaft 2.

[0046] More specifically: the lower shaft elastic retaining ring 4 limits the rotation shaft lower bearing 15 and the rotation shaft 2, the bearing retaining ring 3 axially limits the rotation shaft lower bearing 15, and the hole elastic retaining ring 6 is used to support the bearing retaining ring 3, thus axially limiting the rotation shaft 2, the bearing retaining ring 3, the shaft elastic retaining ring 4, the rotation shaft upper bearing 5, the rotation shaft lower bearing 15 and the cylinder 14.

[0047] More specifically: the rotary motor 7 drives the rotary shaft 2 to rotate, which in turn drives the drive gear 9 to rotate. Since the drive gear 9 meshes with the driven gear 10, the driven gear 10 rotates. Since the driven gear 10 meshes with the gear ring 11, the gear ring 11 rotates, which in turn drives the platform 13 to rotate.

[0048] More specifically: even after disassembling the drive gear 9, driven gear 10, gear ring 11, rotating shaft 12, and platform 13, the rotating mechanism can still perform its rotational function.

[0049] More specifically: The rotating shaft 2 can not only directly mount the equipment that needs to rotate, but also upgrade the rotation function through the driving gear 9, driven gear 10, gear ring 11, rotating shaft 12 and platform 13 on the rotating shaft 2. It has a simple structure, is easy to replace, and can be used in two rotation environments.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
