Description

Technical Field

[0001] This utility model relates to an unmanned vessel, specifically a hydrofoil unmanned vessel. Background Technology

[0002] Unmanned surface vessels (USVs) offer advantages such as low cost and high maneuverability, and are gradually permeating all aspects of people's lives, bringing convenience in areas such as fisheries surveying, power line inspection, disaster relief, water quality monitoring, and express delivery. However, current USV applications in express delivery and disaster relief require high speed and long endurance, which are currently limited.

[0003] Traditional unmanned vessels mostly use propeller propulsion. The principle is that the propeller generates thrust as it rotates in the water, propelling the vessel forward. This is based on Newton's third law—the propeller pushes water backward, and the water exerts a reaction force on the propeller and the hull. The power system of traditional unmanned vessels is driven by an electric motor or engine, with speed controlled by adjusting the motor speed or engine throttle. Their large hull-to-water contact area results in significant wave resistance, limiting speed increases. High-speed navigation leads to rapid energy consumption and reduced range. When navigating in waves, the hull experiences severe pitching, affecting stability and mission execution. Utility Model Content

[0004] The purpose of this invention is to provide a hydrofoil unmanned surface vessel that improves the vessel's speed and load-bearing capacity.

[0005] The technical solution to achieve the purpose of this utility model is as follows: a hydrofoil unmanned surface vessel, comprising a hull, a tail rudder, a motor, a hydrofoil, a motor connecting frame, and a servo motor, wherein the hull is streamlined and has an interface for the hydrofoil; a servo motor is installed at the stern of the hull, and a rocker arm is installed on the servo motor to control the tail rudder; a through hole is provided on the bottom surface of the hull, and the upper and lower surfaces of the motor connecting frame are respectively connected to the hull and the motor; a circular through hole is provided inside the hull to cooperate with the hydrofoil so as to connect it through a short pin, thereby realizing the cooperation between the hydrofoil and the hull.

[0006] Compared with the prior art, the significant advantages of this utility model are: 1) This utility model has a simple structure. When the hydrofoil unmanned surface vessel is in wing-wing mode, the combined action of the rudder and the tail rudder enables the hull to produce a safe inward tilting turn, thus exhibiting good turning performance. 2) This utility model uses a hydrofoil with a certain angle of attack to the incoming current, and the wing section has an camber, thus generating lift and enhancing the vessel's load-bearing capacity. At the same time, in wing-wing mode, the hull is lifted off the water surface. At this time, only the wing column is in contact with the water surface, and only the wing surface is underwater. This results in low drag, higher speed with the same power, lower energy consumption, and better endurance. Attached Figure Description

[0012] like Figures 1-4 As shown, a hydrofoil unmanned surface vessel (USV) design includes a hull 1, a tail rudder 2, a motor 3, hydrofoils 4, a motor mounting bracket 6, and a servo motor 9. The hull 1 has a streamlined design and an interface for the hydrofoils 4. The servo motor 9 is located at the stern of the hull 1, and a rocker arm 10 is mounted on the servo motor 9 to control the tail rudder 2. Through holes are provided on the bottom surface of the hull 1, and through holes are provided on both the top and bottom surfaces of the motor mounting bracket 6. The mounting bracket 6 is connected to the hull 1, and the motor 3 is connected to the mounting bracket 6, using screws 7 and nuts 8. Inside the hull, through holes are provided to mate with the hydrofoils, allowing connection via short pins 5 to achieve the engagement between the hydrofoils 4 and the hull 1. During movement, the servo motor 9 controls the rocker arm 10 to control the tail rudder 2, achieving steering of the USV. The motor 3 rotates to generate propulsion, controlling the ship's speed and thus controlling the lift gained by the hydrofoils 4 and the tail rudder 2.

[0013] Furthermore, the hull 1 includes two hydrofoil splicing interfaces, a rudder mounting groove, a stern rudder connection hole, and a bottom circular through hole, and is streamlined in shape. The hydrofoil splicing interfaces are located at the front fifth of the hull, and each hydrofoil splicing interface has the same shape and height and is an elliptical cylinder with a circular through hole. The rudder mounting groove has the same shape as the bottom surface of the rudder and is used to install the rudder. The stern rudder connector is located at the stern of the hull.

[0014] Furthermore, the tail rudder 2 includes a wing surface and a wing post, which have connection holes and are connected to the hull 1 via a pivot shaft. An interface for the rocker arm 10 is provided on its upper part.

[0015] Furthermore, the hydrofoil 4 includes a wing column and a wing surface. The wing column has an elliptical cross-sectional shape, and the wing surface has a streamlined shape. The chord length of the wing surface should be the same as the chord length of the wing surface of the tail rudder 2.
