Description

Technical Field

[0001] This utility model relates to the field of unmanned vessels, and more specifically, to an intelligent unmanned vessel. Background Technology

[0002] With continuous breakthroughs in unmanned systems and sensing technologies, the maturity of autonomous driving technology, and the increasing demands for measurement accuracy, the design requirements for unmanned vessels are constantly evolving, requiring greater maturity and precision. In fields such as environmental monitoring, marine exploration, and waterway management, the demand for high-precision measurement equipment is increasing daily. Especially in the era of big data, data-driven decision-making is becoming increasingly important, and the need for accurate data is driving the development of unmanned vessel technology.

[0003] Unmanned surface vessels (USVs) can perform a variety of tasks without human intervention, such as data collection, image capture, and location positioning, greatly improving operational efficiency and safety. Traditional USV designs are mostly simple and practical, but USVs encounter significant resistance during navigation, which not only affects their speed but also increases energy consumption, limiting their endurance and work efficiency, and making it difficult to cope with changing sea conditions and currents. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an intelligent unmanned vessel.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] An intelligent unmanned surface vessel (USV) includes a hull, a drive unit installed at the bottom of the hull, a camera, a GNSS receiver, and an antenna installed on the top surface of the hull, the hull having a streamlined overall structure, a sharp wedge-shaped bow, downward extensions on both sides of the hull extending from the bow to the stern, the stern of the hull gradually tapering, and a smooth transition at the bottom of the hull.

[0007] Trimaran buoys are fixedly installed on both sides of the unmanned vessel's hull via brackets.

[0008] As a further description of the above technical solution: the hull of the unmanned vessel is made of high-molecular polyester carbon fiber material.

[0009] As a further description of the above technical solution: a protective net is installed around the bottom of the unmanned vessel hull corresponding to the drive unit, and the protective net is a blade-type mesh structure.

[0010] As a further description of the above technical solution: the protective net is made of corrosion-resistant material.

[0011] As a further description of the above technical solution: a depth sounder is installed on the bottom of the unmanned vessel hull.

[0012] As a further description of the above technical solution: the top of the unmanned vessel hull is provided with a camera compartment for installing a camera. The camera compartment is a cylindrical structure and can be detachably installed on the hull by bolts.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] The intelligent unmanned boat in this solution adopts a streamlined design, which allows water to flow more smoothly along the surface of the hull when navigating in water, reducing turbulence and eddies, thereby effectively reducing water resistance to the hull.

[0015] The sharp bow reduces frontal drag, improving the unmanned vessel's navigation efficiency and stability. The smaller bow angle also helps to divide the water flow, allowing it to flow smoothly along both sides of the hull and reducing turbulence.

[0016] The stern tapers slightly and the bottom transitions smoothly to avoid creating excessively large tail vortices, thus improving the stability and seakeeping of the unmanned vessel.

[0017] The downward extensions on both sides of the hull further reduce underwater resistance and stabilize water flow, preventing the formation of excessive lateral vortices.

[0018] Furthermore, the trimaran buoys installed on both sides of the hull further enhance the buoyancy and stability of the vessel in complex sea conditions. The buoys can effectively disperse the pressure and impact on the hull, reducing damage caused by waves or collisions.

[0019] In summary, the intelligent unmanned vessel of this invention features a unique design, compact structure, and light weight, offering significant advantages in improving operational efficiency, enhancing navigation safety, and adapting to complex aquatic environments. It is highly suitable for modern marine operations and tasks such as waterway monitoring, surveying, and inspection. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-3 An intelligent unmanned surface vessel (USV) includes a hull 1. A drive unit 2 is mounted on the bottom of the hull 1. The drive unit 2 employs a ducted structure to enclose the propeller, protecting the blades from entanglement with seaweed and improving propulsion efficiency while optimizing water flow guidance. A camera 3, a GNSS 4, and an antenna 5 are mounted on the top surface of the hull 1. The antenna 5 is a fiberglass omnidirectional antenna. A depth sounder 9 is mounted on the bottom of the hull 1. A camera housing 10 for mounting the camera 3 is located on the top of the hull 1. The camera housing 10 has a cylindrical structure and is detachably mounted to the hull 1 using bolts.

[0027] The unmanned surface vessel (USV) hull 1 features a streamlined structure, optimized for hydrodynamics, significantly reducing water resistance during navigation and enhancing stability. The bow of USV hull 1 has a sharp wedge-shaped design, similar to a V-shape. This effectively reduces frontal drag during navigation and decreases the reaction force from water flow impact. Furthermore, the smaller bow angle facilitates water flow separation, allowing the water to be smoothly divided along both sides of the hull (e.g., ...). Figure 3 (As shown), reduce turbulence.

[0028] The lines on both sides of the unmanned vessel hull 1 are relatively straight, and both are provided with downward extensions 6. The extensions 6 start from the bow and end at the stern, blending naturally with the smooth curve of the bottom to form a narrow underwater cross-section, which can further reduce underwater resistance and stabilize the water flow, avoiding the formation of too many lateral vortices.

[0029] The stern of the unmanned surface vessel (USV) hull 1 tapers slightly but maintains a certain width to avoid forming excessively large tail vortices, thereby improving the USV's stability and seakeeping. The bottom of the USV hull 1 has a smooth transition, which optimizes the manufacturing process and reduces turbulence and current interference during navigation, thus enhancing the USV's speed performance and endurance.

[0030] Both sides of the unmanned surface vessel (USV) hull 1 are fixedly equipped with trimaran buoys 7 via brackets. These trimaran buoys work closely with the main hull structure to provide additional buoyancy, helping to stabilize the vessel and resist the effects of external forces such as wind and waves. Combined with the horizontal control of the control system, this effectively improves the stability of the USV's operational attitude, especially in wave-prone environments, significantly enhancing its anti-capsulation capability.

[0031] The hull of the unmanned surface vessel (USV) is made of high-molecular-weight polyester carbon fiber, a high-performance, high-strength, lightweight material that ensures both hull strength and weight reduction. This USV weighs only 7 kg, allowing for easy single-person operation, rapid deployment, and adaptability to various mission scenarios, enabling effective operation in extremely shallow water. Structural optimization has been implemented to reduce unnecessary materials, meeting both lightweight and environmental requirements while maintaining structural rigidity and strength. This reduces hull weight and water resistance by more than 10%. Stress testing analysis shows it can withstand external forces of ≥30 kg, effectively improving the USV's environmental adaptability.

[0032] A protective net 8 is installed around the bottom of the unmanned vessel hull 1, corresponding to the drive unit 2. The protective net 8 has a blade-type mesh structure, which facilitates water flow and reduces resistance. It is used to cover the drive unit 2 and prevent it from being affected by aquatic plants and fishing nets, effectively reducing the chance of it getting entangled in aquatic plants by 60%. The protective net 8 is made of corrosion-resistant material, which can ensure its durability in the underwater environment.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
