[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0037] Example 1:

[0038] like Figures 1-6 As shown, a multi-functional unmanned surface vessel platform includes a hull 1, and also includes:

[0039] Battery 2 and propulsion mechanism 3;

[0040] The battery 2 is installed on the top platform of the hull 1. The battery 2 is preferably a waterproof battery. Placing the battery 2 at a high position can reduce the risk of the hull's center of gravity shifting and ensure the balance of the hull during navigation. The propulsion mechanism 3 is installed at the bottom of the hull 1. Two sets of the battery 2 and the propulsion mechanism 3 are symmetrically installed. The propulsion mechanism 3 is electrically connected to the battery 2, providing electrical power to the propulsion mechanism 3 to drive the hull 1 to sail.

[0041] The two sets of batteries 2 symmetrically arranged on the hull 1 not only ensure that the weight distribution on both sides of the hull is uniform during navigation, avoiding navigation deviation caused by uneven weight, but also, when carrying heavier equipment, such as large water quality monitoring equipment or high-precision underwater mapping sonar, in order to avoid the hull's navigation stability being affected by the shift in the center of gravity, the batteries 2 can be moved away from the equipment, thereby restoring the hull to a balanced state. Conversely, if carrying lighter equipment, in order to maintain the balance of the hull, the batteries 2 can be moved appropriately towards the side carrying the equipment. This method of dynamically adjusting the position of the batteries 2 according to the weight of the equipment can effectively maintain the stability of the unmanned vessel's center of gravity and improve the stability and reliability of battery power supply.

[0042] The symmetrically installed propulsion mechanism 3 enables the unmanned vessel to obtain more balanced propulsion force during navigation, thereby improving navigation stability and maneuverability.

[0043] A mounting slot 10 is provided through the center of the hull 1 along its height direction. When the hull 1 is running at low speed, it is usually necessary to perform detailed data collection tasks such as water quality monitoring and underwater topographic mapping. Test equipment is detachably installed in the mounting slot 10 through the mounting plate 11.

[0044] When the hull 1 is running at high speed, in order to reduce fluid resistance during navigation and ensure the stability and speed of the hull, foam is installed in the mounting slot 10. The foam is made of a material with good buoyancy and water resistance, and its density and structure have been optimized. It can effectively fill the space of the mounting slot 10, reduce the turbulence formed by the water flow in the slot, and play a certain role in buffering and protection without adding too much weight. A sealing plate 12 is detachably installed at the bottom of the hull 1 corresponding to the opening of the mounting slot 10 to prevent the foam from falling out of the mounting slot 10. This ensures that even when facing complex flow conditions and strong water flow impacts during high-speed navigation, the foam can always be firmly filled in the mounting slot 10, maintain the smooth shape of the hull, reduce navigation resistance, and ensure the high-speed and stable operation of the unmanned vessel.

[0045] The hull 1 is recessed inward from the middle to the stern, which allows water to flow more smoothly onto the hull surface, effectively suppressing boundary layer separation, reducing eddy current generation, lowering pressure drag and friction drag, thereby improving the hull's propulsion efficiency and achieving a good effect of drag reduction and efficiency enhancement.

[0046] Furthermore, the propulsion mechanism 3 includes a propeller 31, a connecting plate 32, and a protective cover 33 disposed at the stern of the hull 1. The propeller 31 is mounted on the hull 1 via the connecting plate 32. The propeller 31 is preferably an electric propeller.

[0047] One end of the connecting plate 32 is connected to the hull 1, and the other end of the connecting plate 32 is connected to the protective cover 33. This connection method not only ensures the stability of the connection and can withstand the huge reaction force generated when the thruster 31 is running, but also facilitates maintenance and replacement operations in the later stage.

[0048] The protective cover 33 is arranged in a ring shape and is fitted onto the output end of the thruster 31. The main function of the protective cover 33 is to protect the thruster 31 and prevent debris in the water, such as branches and stones, from hitting the thruster 31 during navigation, causing damage to the blades and affecting the normal operation of the thruster. The protective cover 33 is connected to the hull 1 through a connector 34, and the protective cover 33 and the connector 34 are connected by bolts. The advantage of this connection method is that the installation and disassembly process is simple and quick, which greatly facilitates the maintenance, repair and replacement of parts of the thruster 31 and the protective cover 33 in the later stage.

[0049] Furthermore, this unmanned surface vessel (USV) employs a dual-power system and differential steering technology. When the USV needs to turn, the control system 5 reduces or reverses the rotational speed of the thruster 31 on one side of the propulsion mechanism 3 based on preset steering commands or real-time monitored navigation data, while maintaining the other thruster 31 at its normal speed. For example, when performing a left turn, the right thruster 31 maintains its original speed, while the left thruster 31 appropriately reduces its speed. At this time, the thrust on the left side of the hull is less than that on the right side, causing the hull to turn left. This differential steering method eliminates the need for traditional mechanical steering mechanisms, such as rudders. Traditional mechanical steering mechanisms, including the engine and its associated complex mechanical components such as linkages and gears, are not only structurally complex, increasing the weight of the hull and maintenance costs, but are also prone to wear, jamming, and other malfunctions during operation, affecting the reliability and accuracy of steering. In contrast, differential steering technology reduces the use of these mechanical components, simplifies the hull structure, and lowers the complexity of the system and the probability of failure. At the same time, differential steering can achieve faster and more precise steering response, which can significantly improve the operational efficiency and navigation safety of unmanned vessels, especially in narrow waters or operational scenarios that require frequent turning.

[0050] Furthermore, a limiting groove 13 is provided at the bottom of the hull 1 corresponding to the propulsion mechanism 3. The limiting groove 13 is contoured to the propulsion mechanism 3. This contoured design allows the propulsion mechanism 3 to be embedded in the limiting groove 13 during installation. On the one hand, this greatly improves the accuracy and convenience of installing the propulsion mechanism 3, allowing installers to quickly position the propulsion mechanism 3 in the correct position, reducing installation time and operational difficulty. On the other hand, the contoured limiting groove 13 provides a stable support and positioning foundation for the propulsion mechanism 3, effectively limiting the displacement and swaying of the propulsion mechanism 3 during operation. This ensures that it can maintain a stable working posture even under complex water flow impacts and hull pitching conditions, thereby ensuring stable power output from the propulsion system and maintaining the normal navigation of the unmanned vessel.

[0051] The connector 34 is L-shaped, with one end connected to the hull 1 and the other end connected to the protective cover 33. This design cleverly utilizes the space layout, achieving a stable connection without taking up too much of the limited space at the bottom of the hull.

[0052] Meanwhile, the connection between the connector 34 and the outer wall of the protective cover 33 is designed in a contour-like manner, which can ensure that the two fit tightly. In this way, when bearing the huge reaction force generated by the operation of the thruster 31 and the impact force of the water flow on the propulsion mechanism 3, the connection between the connector 34 and the protective cover 33 can evenly distribute the stress, avoiding the loosening or damage of the connection caused by local stress concentration.

[0053] In addition, the connecting plate 32 is provided with several sets of guide plates 321. The connecting plate 32 is inclined along the length direction of the hull 1, and the guide plates 321 are equidistantly distributed along the width direction of the connecting plate 32. The guide plates 321 are vertically arranged on the connecting plate 32. In actual navigation, when the water flows through the inclined connecting plate 32, it can be naturally guided along the inclined direction, thereby reducing the impact angle between the water flow and the connecting plate 32, reducing the turbulence of the water flow, and allowing the water flow to the propeller 31 in a smoother state, creating favorable flow field conditions for the efficient operation of the propeller 31.

[0054] It is worth mentioning that the obliquely arranged connecting plate 32 can increase the draft of the propulsion mechanism 3 and prevent insufficient water flow from causing a reduction in power.

[0055] Furthermore, a guide channel 322 is provided between adjacent guide plates 321, allowing water to flow more concentratedly and faster within the guide channel 322, further improving the flow velocity and stability. Through the synergistic effect of the guide plates 321 and the guide channel 322, the thruster 31 can operate in a more stable and efficient water flow environment, thereby improving the propulsion efficiency of the entire propulsion system, reducing energy consumption, enhancing the navigation performance and handling stability of the unmanned vessel under different operating conditions, and providing power support for the unmanned vessel to perform its missions.

[0056] In addition, the mounting plate 11 is installed on the top surface of the hull 1. The mounting plate 11 is set in relation to the mounting groove 10. When installing the mounting equipment, the equipment can be stably connected to the mounting groove 10 through the mounting plate 11, which enhances the stability and reliability of the equipment installation and prevents the equipment from being displaced or damaged due to shaking or turbulence during the unmanned vessel's navigation.

[0057] The mounting plate 11 has several through holes 14. When installing the mounting equipment, bolts, screws and other connectors can be used through these through holes 14 to firmly fix the equipment to the mounting plate 11, ensuring the stability of the equipment installation. In addition, the through holes 14 can reduce the weight of the mounting plate 11 itself without affecting the structural strength of the mounting plate 11, thereby reducing the impact on the navigation performance of the hull 1 and improving energy utilization efficiency.

[0058] Furthermore, a slot 15 is provided at the bottom of the hull 1, and the sealing plate 12 is installed in the slot 15. The sealing plate 12 is connected to the hull 1 by bolts. When the sealing plate 12 is installed in the slot 15, it can ensure that it is flush with the bottom surface of the hull 1. This will not disrupt the streamline of the hull 1 when it is sailing in the water and reduce the sailing resistance. At the same time, the sealing plate 12 can effectively block the intrusion of water flow. The bolt connection can provide sufficient fastening force to prevent the sealing plate 12 from loosening or falling off due to water flow impact, hull turbulence and other factors during navigation.

[0059] Furthermore, a camera 4 is installed on the hull 1. The camera 4 is connected to the movable mounting plate 41 by bolts. This connection method is not only stable, but also facilitates the later maintenance, replacement, or angle adjustment of the camera 4. The movable mounting plate 41 is connected to the hull 1 through a fixed mounting plate 42. The shape of the fixed mounting plate 42 is precisely adapted to the installation position on the hull 1 and the contour of the movable mounting plate 41. The movable mounting plate 41, the fixed mounting plate 42, and the hull 1 are connected by bolts. This multi-level connection method enables the camera 4 to remain stable when the unmanned vessel is navigating, clearly capture the surrounding environment, provide accurate visual data for the control system 5, and assist the unmanned vessel in autonomous navigation, obstacle avoidance, and mission execution.

[0060] It should be further explained that a control system 5 is also installed on the hull 1, and the control system 5 is electrically connected to the battery 2, the camera 4 and the propulsion mechanism 3 respectively.

[0061] The control system 5 can monitor key parameters such as battery power, voltage, and current of battery 2 in real time. During the unmanned vessel's mission, the control system 5 intelligently adjusts the output power of battery 2 according to the power demand of the onboard equipment and the navigation conditions, striving to maximize battery endurance while ensuring the normal operation of each device and avoiding unnecessary energy loss.

[0062] The camera 4 quickly transmits the high-definition images captured in real time to the control system 5. The control system 5 can perform in-depth analysis and recognition of these images. Through this process, the unmanned vessel can accurately perceive the surrounding environment, identify obstacles in front, recognize waterway markings, or monitor abnormal conditions on the water surface.

[0063] The electrical connection between the control system 5 and the propulsion mechanism 3 is the core of the unmanned vessel's flexible control. Based on the preset navigation path planning, real-time collected environmental data, and remote commands from the operator, the control system 5 can precisely adjust parameters such as the rotation speed and steering angle of the thruster 31 in the propulsion mechanism 3. In complex and changeable aquatic environments, such as narrow rivers and areas with rapid currents, the control system 5 can quickly and accurately adjust the propulsion force of the two propulsion mechanisms 3, thereby enabling the unmanned vessel to perform operations such as smooth turning, precise acceleration and deceleration, and stable course maintenance.

[0064] It should be noted that the hull 1 is provided with a hatch 21 for installing the battery 2 and the control system 5. A sealing plate 22 is correspondingly provided on the hatch 21. The sealing plate 22 is connected to the hull 1 by a hand-tightening screw 23. A sealing ring is provided between the sealing plate 22 and the hatch 21. The sealing plate 22, the hull 1 and the sealing ring are tightly connected by the hand-tightening screw 23. When the hand-tightening screw 23 is tightened, the sealing plate 22 applies pressure to the sealing ring under the action of the hand-tightening screw 23, so that it tightly fills the gap between the sealing plate 22 and the hull 1, thereby forming an effective sealing barrier to prevent moisture, dust and corrosive substances from entering the cabin and to create a stable and safe operating environment for the internal equipment.

[0065] The design of the hand-tightening screw 23 allows operators to quickly install and disassemble it on-site without the need for additional tools, greatly improving maintenance efficiency. At the same time, operators can accurately control the tightening degree by hand, ensuring a tight connection without damaging the components.

[0066] In addition, a radar 16 is also embedded in the hull 1. The radar is located in the area of ​​the central axis of the hull 1 to ensure that it can monitor the surrounding environment in all directions without blind spots. The radar 16 is firmly embedded in the hull to ensure that the radar 16 can maintain a stable working state even when encountering severe turbulence or water flow impact during navigation.

[0067] Example 2:

[0068] The difference between the unmanned vessel platform in this embodiment and that in embodiment 1 is:

[0069] In this embodiment, the bottom sealing plate 13 can be designed with multiple mounting holes for the installation of other equipment.

[0070] It should be noted that the installation holes enable the equipment installed on the bottom sealing plate 13 to work in conjunction with the hull, helping the unmanned vessel to complete various tasks more comprehensively and efficiently, and expanding the application functions and operating range of the unmanned vessel. For example, in actual operation scenarios, when the unmanned vessel needs to perform aquatic environment monitoring tasks, multi-parameter water quality monitoring instruments can be conveniently installed through these installation holes to collect data such as pH, dissolved oxygen, and ammonia nitrogen content of the water in real time.

[0071] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
