Description

Technical Field

[0001] The present invention relates to the technical field of underwater vehicles, and in particular to a power system for delivering multiple loads to an underwater vehicle. Background Art

[0002] With the continuous development of modern science and technology, underwater vehicles (UVs) are increasingly being used in both military and civilian sectors due to their numerous advantages, such as high concealment, long latency, and wide applicability. Typically, most UVs carry payloads (such as exploration and reconnaissance equipment, and weapons for combat) to complete underwater payload deployment missions in specific sea areas. This requires high efficiency, and such tasks are difficult to complete manually. Therefore, it is of great significance to conduct research on the overall layout design of UVs for the multi-payload deployment process, in order to achieve efficient payload delivery.

[0003] Typically, to better complete deployment tasks in a designated area, an underwater vehicle will carry multiple delivery payloads. Existing delivery methods primarily fix the payloads at designated locations. Once the vehicle reaches the designated delivery area, the payloads are released from their storage locations. This means the payload's storage location is the final delivery location. This delivery method limits the number of payloads an underwater vehicle can carry. Therefore, by installing a multi-payload delivery power system within the vehicle, the payloads can be transferred within the vehicle's cabin, ensuring they reach the designated delivery area and complete the delivery operation. This can significantly improve the delivery efficiency of underwater vehicles. Therefore, a power system for delivering multiple payloads from underwater vehicles is needed.

[0004] In the prior art, some solutions provide internally mounted payload compartments suitable for underwater vehicles. These compartments include a payload compartment, a stirrup mechanism, a release mechanism, and so on. However, there is no power system inside the compartment for changing the load's position. Therefore, the vehicle primarily carries two payloads, which are arranged on the left and right sides of the compartment. Once the payload reaches the drop zone, it is released via a release mechanism. This solution does not incorporate a power system inside the vehicle to change the drop zone. Furthermore, for devices equipped with a power system, the objects they release are often relatively small, placing less demanding requirements on the layout of the power system inside the compartment. However, for large, heavy-mass drop payloads, such devices are no longer suitable.

[0005] Therefore, those skilled in the art are committed to providing a power system for delivering multiple payloads to an underwater vehicle, which can maximize the use of the storage space inside the vehicle and carry as much payload as possible. Summary of the Invention

[0006] In view of the defects in the prior art, the technical problem to be solved by the present invention is how to provide a power system for multi-load delivery of an underwater vehicle that can carry as much load as possible.

DETAILED DESCRIPTION

[0030] The following describes preferred embodiments of the present invention to make its technical content clearer and easier to understand. The present invention can be embodied in many different forms of embodiments, and the scope of protection of the present invention is not limited to the embodiments mentioned herein.

[0031] In the drawings, components with identical structures are denoted by the same reference numerals, and components with similar structures or functions are denoted by similar reference numerals. The size and thickness of each component shown in the drawings are arbitrary and are not limited by the present invention. For clarity, the thickness of components in some places in the drawings is appropriately exaggerated.

[0032] The present invention provides a power system for delivering multiple loads to an underwater vehicle, which enables the carrying and delivery of multiple loads by the underwater vehicle.

[0033] like Figure 1 As shown, the power system for multiple payload delivery from an underwater vehicle in this embodiment includes a motor 4, a speed changer 5, a main rotating shaft 1, a suspension device 7, and a hatch crank 10. The motor 4 is mounted at the bow of the vehicle. The output of the motor 4 is connected to the input of the speed changer 5, and the main rotating shaft 1 is connected to the output of the speed changer 5. The rotation output of the motor 4 is regulated by the speed changer 5 and then transmitted to the main rotating shaft 1, driving the main rotating shaft 1 to rotate. The suspension device 7 is mounted on the main rotating shaft 1 and rotates with it. The suspension device 7 carries a payload 9, and the rotation of the suspension device 7 enables the payload 9 to be transferred within the cabin. The main rotating shaft 1 is also mounted with a hatch crank 10, which is used to control the opening and closing of the vehicle's hatch.

[0034] To enable rotation of the main rotating shaft 1, a tail bearing 2 and a fore bearing 3 are mounted on the shaft. The fore bearing 3 is connected to the output of the speed change device 5, while the tail bearing 2 is connected to the transverse bulkhead 8 of the vehicle. The main rotating shaft 1 is fixed to the center of the vehicle's cross section by the fore and aft bearings 3 and 2. Driven by a motor 4, the main rotating shaft 1 rotates perpendicular to the vehicle's cross section. In this embodiment, the main rotating shaft 1 has a hollow hexagonal structure, which accommodates the wiring required for the vehicle's electrical equipment.

[0035] The suspension device 7 is provided with a number of clamps along the circumference, forming a structure similar to a propeller. In this embodiment, the number of clamps is 3, and the load 9 is clamped between two adjacent clamps. There are multiple suspension devices 7, which are distributed along the axial direction of the main rotating shaft 1. In order to achieve the positioning of the suspension device 7, a fastening flange 6 is also provided on the main rotating shaft 1. The suspension device 7 is limited by the fastening flange 6 to ensure the axial position of the suspension device 7 on the main rotating shaft 1. Figure 1 As shown, a through hole is opened on the clamp of the suspension device 7 for reducing weight and allowing water to pass through, thereby facilitating the communication of internal fluid.

[0036] like Figure 2 As shown, a ball bearing 12 and a bearing flange 11 are provided at the head end bearing 3 of the main rotating shaft 1, and a transmission shaft 13 passes through the ball bearing 12. A fastening screw hole 14 is opened on the bearing flange 11 for fastening the bearing flange 11.

[0037] like Figure 3As shown, the transmission 5 is fixedly connected to the cabin via a transmission flange 15. The transmission 5 houses a multi-gear transmission mechanism that reduces the speed of the motor 4 and increases the torque, thereby protecting the motor 4. The gear design of the transmission 5 can be tailored to the actual parameters of the motor 4. The transmission drive shaft 16 of the transmission 5 drives the drive shaft 13 to rotate.

[0038] like Figure 4 As shown, motor 4 is fixedly connected to the hull via motor flange 18 and is controlled according to the launch requirements. A bracket 17 is attached to the exterior of motor 4, securing it to the bow of the vehicle. Bracket 17 is a rectangular cage that protects motor 4 and reduces vibration. Motor output 19 is connected to the speed changer 5 for outputting the motor's power. In this embodiment, motor 4 is waterproof and deep-water pressure-resistant, adapting to the operating environment of underwater vehicles.

[0039] like Figure 5 As shown, the door crank 10 is an L-shaped crank with a sleeve 20 at one end, which allows the door crank 10 to be mounted on the main rotating shaft 1. A bearing is disposed within the sleeve 20, allowing the door crank 10 to rotate relative to the main rotating shaft 1. A lock slot 22 is disposed at the other end of the door crank 10, within which is a lock tongue 21 connected to the door. When the vehicle reaches the payload delivery area, the door crank 10 rotates, causing the lock tongue 21 to move relative to the lock slot 22. When the lock tongue 21 reaches the notch of the lock slot 22, it separates from the lock slot 22, releasing the door and the lock tongue 21 together, completing the next step of payload delivery.

[0040] The preferred embodiments of the present invention have been described in detail above. It should be understood that numerous modifications and variations based on the concepts of the present invention can be made by one of ordinary skill in the art without inventive effort. Therefore, any person skilled in the art can arrive at a solution based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the prior art.
