Description

Technical Field

[0001] The present invention relates to the technical field of hydrofoil boat equipment, and particularly to an unmanned catamaran modular adaptive hydrofoil boat. Background Art

[0002] A hydrofoil boat is a high-speed ship that generates lift through hydrofoils to lift the hull above the water surface. Hydrofoils are wing-shaped structures installed under the hull. When the ship speed increases, the lift generated by the hydrofoils causes the hull to leave the water surface, reducing resistance and thus enhancing speed and fuel efficiency. Hydrofoil boats have the advantages of high speed, smoothness, and high efficiency. However, in actual use, there are many problems. Firstly, since the hydrofoils protrude significantly from the bottom of the hull, the hull is prone to collision and damage to the hydrofoils when used in shallow water environments. Secondly, due to the wave motion in the water, the non-steady change of the water flow velocity and pressure distribution around the hydrofoils occurs. According to Bernoulli's principle, the lift generated by the hydrofoils fluctuates accordingly, easily causing the lift imbalance of the hydrofoils and resulting in the inability of the hull to ensure the stability of navigation. Summary of the Invention

[0003] Aiming at the problems that the current hydrofoil boats are prone to collision when used in shallow waters or low water levels and cannot ensure the hull stability in water waves, the present invention provides an unmanned catamaran modular adaptive hydrofoil boat.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions:

[0005] An unmanned catamaran modular adaptive hydrofoil boat includes a hull, pontoons, a hydrofoil mechanism, and a controller. A plurality of modular cabins are detachably connected to the top of the hull. The pontoons are fixed to the bottom of the hull, and a driving assembly is arranged at the rear of the pontoons. The hydrofoil mechanism includes a first hydrofoil mechanism and a second hydrofoil mechanism. Both the first hydrofoil mechanism and the second hydrofoil mechanism include a telescopic rod and a hydrofoil plate. One end of the telescopic rod is fixedly connected to the bottom of the hull, and the other end is rotatably connected to the hydrofoil plate through a first rotating shaft. The hydrofoil plate includes a base plate and side plates located on both sides of the base plate. A first motor is fixed to the base plate, and the first motor is in transmission connection with the first rotating shaft for driving the base plate to rotate relative to the telescopic rod. Each side plate is rotatably connected to the base plate through a second rotating shaft. A second motor is fixed to the base plate, and the second motor is in transmission connection with the second rotating shaft for driving the side plate to rotate relative to the base plate.

[0006] Furthermore, there are two pontoons, and U-shaped connecting frames are fixedly connected to the tops of both. A plurality of U-shaped connecting seats are fixedly connected to the tops of the connecting frames, and the rear parts of the connecting frames protrude from the pontoons.

[0007] Further, the edges of both ends of the hull extend outward to form extension parts, and the bottoms of the ends of each extension part protrude outward to form connecting parts, and the connecting parts are adaptively arranged in the connecting seats and are connected to the connecting seats through pin shafts.

[0008] Further, the buoy is divided into a first connecting section and a second connecting section. The first connecting section is frustum-shaped, the second connecting section is cylindrical, the first connecting section is located at the front end of the second connecting section, and the first connecting section tilts upward relative to the second connecting section.

[0009] Further, handles are fixedly connected to both the front and rear sides of the top of the connecting frame.

[0010] Further, the driving assemblies are arranged at the rear parts of the two buoys. Each driving assembly includes a driving motor, a connecting rod, and a propeller. The top of the connecting rod is fixedly connected to the connecting frame, the bottom is fixedly connected to the driving motor, and the driving motor is in transmission connection with the propeller through a transmission shaft.

[0011] Further, the first hydrofoil mechanism is fixed to the rear part of the hull, and the two second hydrofoil mechanisms are respectively fixed to the left and right sides of the front part of the hull. The volume of the hydrofoil plate in the first hydrofoil mechanism is larger than the volume of the hydrofoil plate in the second hydrofoil mechanism.

[0012] Further, in the second hydrofoil mechanism, third motors are fixed to both the base plate and the side plate, and flaps are connected to the rear side edges of the base plate and the side plate through third rotating shafts. The third motors are in transmission connection with the third rotating shafts to drive the flaps to rotate.

[0013] Further, the telescopic rod includes a first sleeve, a second sleeve, and a telescopic motor. The second sleeve is sleeved outside the first sleeve, one end of the telescopic motor is fixedly connected to the first sleeve, and the other end is fixedly connected to the second sleeve.

[0014] Further, a plurality of sensors are mounted on the hull, and the controller controls the first hydrofoil mechanism, the second hydrofoil mechanism, the driving assembly, and the telescopic rod by receiving the signals of the sensors.

[0015] The beneficial effects of the present invention are as follows: By the cooperation of the first hydrofoil mechanism and the second hydrofoil mechanism, the present invention can significantly enhance the stability and seaworthiness during navigation through the wide-bottom structure formed by the two, reduce lateral sway, and optimize the lift distribution of the hydrofoil plate, effectively reducing the navigation resistance. In the present invention, the controller cooperates with the telescopic rod to flexibly adjust the positions of the first hydrofoil mechanism and the second hydrofoil mechanism according to different speeds. When navigating at low speeds or in shallow waters, the hydrofoil mechanism can be retracted to reduce resistance, reduce friction, and improve consumption efficiency. While during high-speed cruising, the hydrofoil mechanism can be quickly extended to provide sequential lift, significantly enhancing the speed and stability. In the present invention, the side plate can flexibly change the angle relative to the base plate according to information such as ship speed, load, and water conditions, enabling the hydrofoil plate to maintain appropriate lift and minimum resistance under different working conditions, thereby improving the speed and fuel efficiency of the hydrofoil ship, enhancing maneuverability and stability, and extending the service life of the equipment. In the present invention, the hydrofoil mechanism can rotate relative to the telescopic rod, and the flap can rotate relative to the base plate and the side plate. Among them, the flap can optimize the lift and resistance distribution by dynamically adjusting the hydrofoil profile shape or angle, enhance high-speed stability and low-speed maneuverability, and improve seaworthiness under complex water conditions; the overall rotation of the hydrofoil mechanism enables the hydrofoil plate to synchronously adjust the overall inclination angle according to navigation requirements (such as turning, accelerating, or wave conditions), further reducing navigation resistance, enhancing steering flexibility, while simplifying the mechanical structure and reducing energy loss. The coordinated design of the overall rotation of the hydrofoil plate and the rotation of the flap can effectively extend the service life of the hydrofoil mechanism, enhance system redundancy safety, and is used to achieve high-speed navigation and complete multifunctional tasks in complex water environments.

Detailed implementation mode

[0023] The present invention discloses an unmanned catamaran modular adaptive hydrofoil boat. The following is a specific description of an implementation mode of the present invention with reference to the accompanying drawings.

[0024] Combined with Figure 1 and Figure 2 As shown, an unmanned catamaran modular adaptive hydrofoil boat includes a hull 1, pontoons, a plurality of hydrofoil mechanisms and a controller. A plurality of modular cabins are detachably connected to the top of the hull 1. Workers can flexibly adjust the types, positions and quantities of the modular cabins according to the actual use situation of the hydrofoil boat. The edges of the front end and the rear end of the hull 1 extend outward to form extension parts, and a connecting part 2 protrudes downward from the bottom of the end of each extension part. There are two pontoons, and connecting frames 3 are fixedly connected to the tops of both. In the present invention, the cabins on the hull 1 adopt a modular design, and functional partitions such as passenger cabins and power cabins can be flexibly configured according to needs. The functional partitions such as passenger cabins and power cabins are detachably connected to the hull 1, which can facilitate the rapid replacement of each cabin of the hydrofoil boat to adapt to different waters and usage situations. Moreover, by separately manufacturing and independently maintaining the pontoons and the hull 1, the construction cost and maintenance difficulty are effectively reduced. The connecting frame 3 is U-shaped, and two U-shaped connecting seats 4 are fixedly connected to the top of the connecting frame 3. The two pontoons are respectively arranged on the left and right sides of the bottom of the hull 1 through the connecting frame 3, and the connecting part 2 is adaptively arranged in the connecting seat 4 and is detachably connected to the connecting seat 4 through a pin shaft. The front and rear sides of the top of the connecting frame 3 are fixedly connected with handles 5, which are convenient for users to hold and take through the handles 5.

[0025] As Figure 3 shown, the pontoon is divided into a first connecting section 8 and a second connecting section 9. The first connecting section 8 is frustum-shaped, and the second connecting section 9 is cylindrical. The top of the second connecting section 9 is fixedly connected to the bottom of the connecting frame 3. The first connecting section 8 is located at the front end of the second connecting section 9, and the first connecting section 8 tilts upward relative to the second connecting section 9 for reducing resistance.

[0026] As Figure 4As shown, the rear parts of the connecting frames 3 all protrude from the pontoons. Driving assemblies are provided at the rear parts of both pontoons. The driving assembly includes a driving motor, a connecting rod 7, and a propeller 6. The top of the connecting rod 7 is fixedly connected to the rear part of the protruding connecting frame 3. The bottom of the connecting rod 7 is fixedly connected to the driving motor. The driving motor is drivingly connected to the propeller 6 through a transmission shaft. The driving motor generates power by driving the propeller 6 to rotate, which is used to provide a power source for the whole.

[0027] Combined with Figure 5 and Figure 6 As shown, the hydrofoil mechanism is fixedly connected to the bottom of the hull 1. The hydrofoil mechanism includes a first hydrofoil mechanism and two second hydrofoil mechanisms. The first hydrofoil mechanism is located at the middle position of the rear part of the hull 1, and the two second hydrofoil mechanisms are respectively located on the left and right sides of the front part of the hull 1. The first hydrofoil mechanism and the second hydrofoil mechanism both include a telescopic rod and a hydrofoil plate 12. The volume of the hydrofoil plate 12 in the first hydrofoil mechanism is larger than that of the hydrofoil plate 12 in the second hydrofoil mechanism. The telescopic rod includes a first sleeve 10, a second sleeve 11, and a telescopic motor. The second sleeve 11 is sleeved outside the first sleeve 10. One end of the telescopic motor is fixedly connected to the first sleeve 10, and the other end is fixedly connected to the second sleeve 11. The top end of the first sleeve 10 is fixedly connected to the bottom of the hull 1. The bottom end of the second sleeve 11 is rotationally connected to the hydrofoil plate 12 through a first rotating shaft. The telescopic motor drives the second sleeve 11 to vertically expand and contract along the first sleeve 10. When starting, it can drive the second sleeve 11 to slide downward along the first sleeve 10, extend relative to the first sleeve 10 to provide lift, and when the hydrofoil boat is moored or enters shallow water areas, it drives the second sleeve 11 to slide upward along the first sleeve 10 and retract relative to the first sleeve 10 to avoid collision with the bottom of the water. In the present invention, the telescopic rod drives the hydrofoil plate 12 to achieve telescopic changes, and the position of the hydrofoil mechanism can be flexibly adjusted according to different sailing speeds and water conditions. When sailing at low speeds or in shallow water areas, the hydrofoil mechanism can be retracted to reduce resistance, reduce friction, and improve consumption efficiency. While when cruising at high speeds, the hydrofoil mechanism can be quickly deployed to provide sequential lift, thereby significantly improving the sailing speed and stability. The present invention utilizes the wide-bottom structure formed by the cooperation of the first hydrofoil mechanism and the second hydrofoil mechanism to enhance stability and seaworthiness, reduce lateral sway, and at the same time significantly expand the load space and utilization rate of the hull 1. Moreover, the cooperation of the first hydrofoil mechanism and the second hydrofoil mechanism optimizes the lift distribution of the hydrofoil plate 12 and reduces the sailing resistance.

[0028] In the first hydrofoil mechanism and the second hydrofoil mechanism, a second motor is fixedly connected to the substrate 1201 at a position adjacent to the side plate 1202, and a plurality of first sleeves are fixedly connected to the end face. Second rotating shafts 1203 are fixedly connected to the end faces of the side plates 1202 adjacent to the substrate 1201, and the second rotating shafts 1203 are arranged inside the first sleeves. Gears are fixed to the second rotating shafts 1203. The second motor is connected to a speed reducer, and the transmission shaft of the speed reducer is connected to a gear that can be adaptively meshed with the second rotating shaft 1203. Under the action of the second motor, the second rotating shaft 1203 and the side plate 1202 rotate relative to the substrate 1201, thereby driving the side plate 1202 to change the angle with respect to the substrate 1201, and the lift-drag ratio at different sailing speeds can be optimized. The present invention can change the angle between the side plate 1202 and the substrate 1201 according to variable working conditions such as ship speed, load, and sea conditions, so that the hydrofoil 12 can maintain the best lift and the minimum resistance under different working conditions, thereby improving the sailing speed and fuel efficiency of the hydrofoil ship, improving the maneuverability and stability, and extending the service life of the equipment.

[0029] A flap 1204 is provided in the second hydrofoil mechanism. Third motors are fixedly connected to the rear parts of the substrate 1201 and the side plates 1202, and a plurality of second sleeves are fixedly connected to the end faces of the rear ends. A third rotating shaft is fixedly connected to the end face of the front end of the flap 1204, and the third rotating shaft is arranged inside the second sleeve. A gear is fixed to the third rotating shaft. The third motor is connected to a speed reducer, and the transmission shaft of the speed reducer is connected to a gear that can be adaptively meshed with the third rotating shaft. Under the action of the third motor, the third rotating shaft and the flap 1204 rotate relative to the substrate 1201, thereby driving the flap 1204 to change the angles with respect to the substrate 1201 and the side plates 1202, enhancing the low-speed steering accuracy and the high-speed anti-wave and anti-wind ability. In the present invention, the hydrofoil mechanism can perform two rotation modes. One is that the entire hydrofoil mechanism rotates relative to the telescopic rod, and the other is that the flap 1204 can rotate relative to the substrate 1201 and the side plates 1202. Among them, by the way that the flap 1204 rotates relative to the substrate 1201 and the side plates 1202, the shape or angle of the hydrofoil profile can be dynamically adjusted, the lift and drag distribution can be optimized, the high-speed stability and low-speed maneuverability can be enhanced, and the seaworthiness under complex sea conditions can be improved. The overall rotation of the hydrofoil mechanism can enable the hydrofoil 12 to synchronously adjust the overall inclination angle according to the sailing requirements (such as turning, accelerating, or wave conditions), further reducing the sailing resistance and enhancing the turning flexibility, while simplifying the mechanical structure and reducing the energy loss. The collaborative design between the overall rotation of the hydrofoil mechanism and the rotation of the flap 1204 can effectively extend the service life of the hydrofoil mechanism, enhance the system redundancy safety, and provide efficient and reliable technical support for high-speed sailing and multifunctional tasks such as military patrol or rescue.

[0030] A number of sensors are mounted on the hull 1. The sensors are used to detect data such as the position, speed, and water conditions of the hull 1. The controller is connected to the drive assembly, the first hydrofoil mechanism, the second hydrofoil mechanism, and each sensor. The controller controls the drive assembly, the first hydrofoil mechanism, and the second hydrofoil mechanism by receiving the data from each sensor.

[0031] When the hydrofoil boat is in a stationary or low-speed floating motion, the hull 1 floats on the water surface relying on the buoyancy generated by the two pontoons. The drive motor in the drive assembly drives the propeller 6 to rotate to provide the forward power. And as the overall speed increases, the first hydrofoil mechanism and the second hydrofoil generate lift to lift the hull 1 out of the water surface and enter the high-speed gliding stage. At this time, only the first hydrofoil mechanism, the second hydrofoil mechanism, and the propeller 6 are in contact with the water body, so that the resistance of the hydrofoil boat during forward movement is greatly reduced. A number of sensors are mounted on the hydrofoil boat. During navigation, the hydrofoil boat can adjust the height of the hydrofoil plate 12, the angle of the hydrofoil plate 12, and the angle of the flap 1204 in real time through the sensors to achieve dynamic balance of lift and wave disturbance. When the drive assembly decelerates, the lift generated by the first hydrofoil mechanism and the second hydrofoil mechanism weakens, and then the whole hydrofoil boat falls back to the water surface to resume the floating state, which can take into account the high speed, stability and complex sea condition adaptability throughout the process and expand the applicable range.

[0032] Certainly, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions, or substitutions made by those skilled in the art within the essence of the present invention should also fall within the protection scope of the present invention.
