Description

Technical Field

[0001] The present invention belongs to the technical field of underwater vehicle propulsion, and in particular relates to an underwater vehicle propulsion device with high rudder efficiency and low noise. Background Art

[0002] During high-speed movement of underwater vehicles, good maneuverability ensures that the vehicle has strong navigation control and attitude change capabilities, and the hydrodynamic layout often has a significant impact on the vehicle's maneuverability. The maneuverability of an underwater vehicle refers to the ability to change or maintain the vehicle's speed, depth, heading, and attitude through its own devices such as rudders and propellers. Motion stability, inertial characteristics, and maneuverability are three indicators that measure maneuverability. From the perspective of maneuverability, full-motion rudders can improve the vehicle's maneuverability, but stability will be reduced; cross-shaped fins can enhance the vehicle's stability, but will have a certain impact on maneuverability.

[0003] In the tail section of a vehicle, if the rudder is too close to the propeller, it will cause significant disturbances in the propeller's inlet flow field, exacerbating the mutual interference between the fin and rudder, and significantly affecting propulsion efficiency and flow noise. While moving the rudder forward can reduce the mutual interference between the fin, propeller, and rudder, it will significantly shorten the rudder's span, resulting in reduced rudder efficiency.

[0004] In summary, it is urgent to design a device that can meet the needs of the aircraft to change various navigation attitudes while ensuring high rudder efficiency and low noise. Summary of the Invention

DETAILED DESCRIPTION

[0026] To make the technical solutions and advantages of the embodiments of the present invention more clearly understood, exemplary embodiments of the present invention are further described in detail below with reference to the accompanying drawings. It should be noted that the embodiments described are only a portion of the embodiments of the present invention, and are not an exhaustive list of all embodiments. It should be noted that the embodiments of the present invention and the features thereof may be combined with each other unless they conflict.

[0028] The signal assembly and the lifting horse assembly are installed on the sealed cabin body 1, and the propeller assembly is installed at the tail of the sealed cabin body 1;

[0029] The signal assembly includes a signal transmitting component 2, a sensor component 4, an ultra-short baseline positioning component 5 and an antenna component 7, which are sequentially mounted on the sealed cabin body 1 from left to right.

[0030] The lifting horse assembly includes a bow lifting horse component 3 and a stern lifting horse component 6, the bow lifting horse component 3 is installed between the signal transmitting component 2 and the sensor component 4, and the stern lifting horse component 6 is installed between the ultra-short baseline positioning component 5 and the antenna component 7;

[0031] The propeller assembly includes a rim propeller 8, a propeller 9, a transmission shaft component 10 and a rudder component 11; the transmission shaft component 10 is installed at the tail end of the sealed cabin body 1, and the propeller 9 is installed on the transmission shaft component 10; the four rim propellers 8 are distributed in a cross shape, connected to the sealed cabin body 1 through the rudder component 11, and installed at the contraction part of the tail of the sealed cabin body 1.

[0032] Furthermore, the rim thruster 8 includes a duct 12, a rim 13, a rear stator 14, a hub 15, a rotor 16 and a front stator 17; the hub 15 passes through the duct 12 and is placed at the central axis of the duct 12, the front stator 17 is installed at the leading edge of the duct 12, the rear stator 14 is installed at the trailing edge of the duct 12, and a rotor 16 connected to the duct 12 through the rim 13 is provided between the front stator 17 and the rear stator 14.

[0033] Furthermore, a motor stator is provided inside the conduit 12 .

[0034] Furthermore, a main control board, a lithium battery pack, an electric motor and an energy distribution management board are provided inside the sealed cabin body 1. The main control board is communicatively connected to the signal component and the energy distribution management board; the lithium battery pack is electrically connected to the electric motor and the motor stator through the energy distribution management board.

[0035] Furthermore, the motor is fixedly connected to the transmission shaft component 10 .

[0036] Example 2, reference Figure 1-4 This embodiment uses a high-rudder-efficiency, low-noise underwater propulsion vehicle device. The propeller 9 serves as the main propulsion device, with the thrust vector being in the plane where the center axis of the sealed cabin hull 1 is located. The rim thruster 8 serves as the auxiliary propulsion device, with the thrust vector being in the plane where the longitudinal sections of the four rudder components 11 are located.

[0037] When the aircraft is in a straight-line state, the rim thruster 8 and the propeller 9 have thrust vectors in parallel, and the rim thruster 8 can provide additional thrust for the aircraft.

[0038] When the aircraft device is deflected, the two perpendicular rudder components 11 deflect, and the thrust vectors of the two rim thrusters 8 connected thereto deflect along with the rudder components 11, assisting the aircraft in completing the steering;

[0039] When the aircraft is in a buoyant state, the two horizontal rudder components 11 are deflected, and the thrust vectors of the two rim thrusters 8 connected thereto are deflected along with the rudder components 11, providing additional thrust for the aircraft to ascend and descend.

[0040] On the basis of the propeller assembly of the traditional aircraft, the present invention adds four rim propellers 8, and combines them with the functions of the four rudder components 11 respectively, so that the aircraft can not only obtain greater thrust, but also move in a controlled manner in six spatial degrees of freedom, and has the characteristics of strong adaptability to different navigation postures, excellent performance and high safety.

[0041] Example 3, reference Figure 1-4 This embodiment uses a high-efficiency, low-noise underwater propulsion vehicle device. When the vehicle device is in operation, part of the electrical energy generated by the lithium battery pack is directly transmitted to the motor stator of the rim propeller 8. The motor stator drives the rotor 16 to rotate through electromagnetic force. The other part of the electrical energy is transmitted to the motor, which drives the propeller 9 to rotate through the transmission shaft component 10.

[0042] The energy distribution management board sets up an independently controllable power supply channel to dynamically optimize the electric power distribution ratio of the rim thruster 8 and the propeller 9 in real time according to the navigation status and main control instructions; when the load changes or the battery is limited, it gives priority to ensuring critical propulsion needs and limits non-critical power, controls the energy distribution of the rim thruster 8 and the propeller 9, improves the working efficiency of the underwater vehicle's multi-stage thruster assembly, and enhances its operating stability.

[0043] Through the present invention, four rim thrusters are added to the traditional propeller assembly and combined with the function of the rudder component, the thrust of the aircraft is greatly improved, and controllable movement with six spatial degrees of freedom is achieved, so that it can flexibly adapt to various navigation postures, and significantly enhance navigation performance and safety; the energy distribution management board in the device of the present invention can dynamically optimize the power distribution in real time according to the navigation status and main control instructions through an independent controllable power supply channel, and give priority to key propulsion needs in scenarios where load changes or battery power is limited, avoid energy waste, effectively improve energy utilization efficiency, and extend the flight time of the aircraft.

[0044] The present invention effectively improves the unreasonable layout of the rudder and propeller in the tail retraction section of the vehicle, avoids the flow field disturbance and mutual interference caused by the rudder being too close to the propeller, improves the propulsion efficiency and reduces the flow noise.
