Description

Technical Field

[0001] The present invention relates to hydrofoil storage technology, and particularly to a lifting and storage assembly for hydrofoils on hydrofoil boats. Background Art

[0002] The design of hydrofoil boats indeed makes ingenious use of the lift generated by hydrofoils, enabling the hull to partially or completely lift out of the water. This not only significantly reduces the resistance during navigation but also improves the ship's ability to resist wave impacts. However, the design of hydrofoil boats also comes with some challenges, especially in adapting to different water depths and environmental conditions.

[0003] First, regarding the length of the struts on hydrofoil boats, longer struts do provide sufficient lift for the hull, but this also limits the navigation and docking capabilities of hydrofoil boats in certain shallow water areas or complex waters. To overcome this limitation, modern hydrofoil boat designs have started to adopt adjustable-height hydrofoil struts. This design allows hydrofoil boats to flexibly adjust the height of the hydrofoils according to water depth, navigation mode, and docking requirements, thus ensuring the safe and efficient operation of the vessel in various environments.

[0004] Second, there is indeed a risk of corrosion when hydrofoils are immersed in water for a long time. To extend the service life of hydrofoils, corrosion-resistant materials need to be used and regular maintenance and servicing are required. In addition, some advanced hydrofoil boat designs have also introduced automatic cleaning systems to reduce the biological and sediment deposits attached to the hydrofoils, further reducing the possibility of corrosion.

[0005] Furthermore, to meet the requirements of hydrofoil boats in different navigation modes, the position of the hydrofoil struts also needs to be adjusted accordingly. For example, in high-speed navigation mode, the hydrofoils may require higher lift to reduce resistance; while in docking or low-speed navigation, the hydrofoils may need to be lowered to reduce interference with the surrounding environment. Therefore, modern hydrofoil boats are usually equipped with advanced control systems that can automatically adjust the position and angle of the hydrofoil struts according to the navigation mode and environmental conditions.

[0006] Finally, for the application requirements of hydrofoil boats in different scenarios, such as navigating in areas with different water depths, docking at piers, performing maintenance or transportation, etc., the adjustable-height hydrofoil design is particularly important. This design not only improves the adaptability and flexibility of hydrofoil boats but also reduces the operation difficulty and cost. At the same time, to ensure the stability of the hydrofoils at different heights, reliable fixing devices and locking mechanisms are also required to prevent accidental movement or detachment of the hydrofoils during navigation.

[0007] Existing hydrofoil lifting and stowing means cover a variety of technical solutions aimed at meeting the requirements of hydrofoil boats under different sailing conditions. Among them, the rotating shaft folding solution and the rotating shaft flipping and lifting design achieve the stowing and deployment of the hydrofoil through rotational movements. Although this design saves space to a certain extent, it places strict requirements on the strength of the rotating shaft to ensure the stability of the hydrofoil during navigation. A high-strength rotating shaft not only increases the manufacturing cost but also may affect the overall reliability of the system. In addition, such solutions often cannot achieve precise height adjustment, limiting the flexible application of hydrofoil boats at different water depths.

[0008] The gear and rack up-and-down lifting solution relies on precise gear meshing to achieve the smooth lifting of the hydrofoil. Although this method can theoretically provide high positioning accuracy, embedding the metal rack undoubtedly increases the weight of the hydrofoil strut, not only increasing the manufacturing cost but also making transportation and installation more difficult. More importantly, once the rack is damaged, the repair cost will be quite high, and the repair process may be relatively complex, affecting the operation efficiency of the hydrofoil boat.

[0009] The hydraulic mechanical lifting solution drives the hydraulic rod through a hydraulic cylinder to move the hydrofoil up and down under the guidance of a guide rod. Although the hydraulic system can provide powerful power and maintain high precision at the same time, this solution also has significant disadvantages. The volume of the hydraulic cylinder and its auxiliary components is relatively large, occupying valuable space inside the hydrofoil. This not only increases the overall weight of the hull but also may have an adverse impact on the sailing performance. In addition, design elements such as guide rods increase the structural complexity while also increasing the resistance during operation, affecting the energy efficiency of the hydrofoil boat.

[0036] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will further introduce the present invention in detail in conjunction with the accompanying drawings.

[0037] Embodiment 1:

[0038] Please refer to Figures 1-3, A lifting and retracting assembly for the hydrofoils on a hydrofoil boat, including a hull 1. A front wing 3 is arranged in front of the hull 1, and the front wing 3 is connected to the hull 1 through a mounting bracket 21.

[0041] A lifting rope 43, which is wound around the outside of the wire winding drum 42, and one end of the lifting rope 43 is arranged at the top of the hydrofoil.

[0042] The specific implementation method is as follows: The lifting unit 4 is the core of the entire assembly. The lifting unit 4 is arranged at both the bow and the stern of the hull 1.

The lifting rope 43 is wound around the outside of the wire winding drum 42. When the driving source 41 drives the wire winding drum 42 to rotate, the wire winding drum 42 rolls up or releases the lifting rope 43, thereby driving the hydrofoil fixed at one end thereof, such as the front hydrofoil 32 or the rear hydrofoil 22, to rise or fall, realizing the lifting and lowering of the hydrofoil;

[0043] The tail wing 2 includes a rear support column 22, a rear hydrofoil 23 and a propeller 24. The rear support column 22 is arranged at the bottom of the mounting bracket 21 located behind the hull 1 and extends to the top of the mounting bracket 21. The outside of the rear support column 22 is slidably connected to the inside of the mounting bracket 21. A propeller 24 is arranged at the bottom of the rear support column 22. A rear hydrofoil 23 is arranged above the propeller 24. The rear hydrofoil 23 is fixedly connected to the rear support column 22. The top of the rear hydrofoil 23 is connected to the bottom end of the lifting rope 43, and the lifting rope 43 is located on the side of the rear support column 22.

[0044] The front wing 3 includes a front support column 31 and a front hydrofoil 32. The front support column 31 is arranged at the bottom of the mounting bracket 21 located in front of the hull 1 and extends to the top of the mounting bracket 21. A front hydrofoil 32 is arranged at the bottom of the front support column 31. The top of the front hydrofoil 32 is connected to the bottom end of the lifting rope 43, and the lifting rope 43 is located on the side of the front support column 31.

[0045] A fixed end head 211 is fixedly installed at the top of the rear hydrofoil 23, and the rear hydrofoil 23 is fixedly connected to the lifting rope 43 through the fixed end head 211.

[0046] The specific implementation is as follows: the tail wing 2 and the front wing 3 have the same orientation and structure, and are respectively installed at the stern and bow of the hull 1 through the mounting bracket 21. The tail wing 2 and the front wing 3 both include pillars, the pillar located at the bow is the front pillar 31, the pillar located at the stern is the rear pillar 22, and hydrofoils, the hydrofoil located at the bow of the hull 1 is the front hydrofoil 32, the hydrofoil located at the stern of the hull 1 is the rear hydrofoil 23, the propeller 24 is installed at the bottom of the rear pillar 22 of the tail wing 2, for providing propulsion power, the propeller 24 includes but is not limited to a fuel propeller, and in this embodiment, the lifting rope 43 is located behind the pillar side.

[0047] Embodiment 2:

[0048] See also Figure 3 and Figure 4 This embodiment provides a technical solution based on the first embodiment: it also includes a locking unit 5, and the locking unit 5 includes:

[0049] A rotating shaft 52, which is fixedly mounted on a side of the mounting bracket 21 close to the hull 1;

[0050] A locking block 51 is rotatably mounted on the outer side of the rotating shaft 52;

[0051] A torsion spring 53 is sleeved on the outside of the rotating shaft 52, one end of the torsion spring 53 is fixedly connected to the mounting bracket 21, and the other end of the torsion spring 53 is fixedly connected to the locking block 51;

[0052] A limit block 54, which is fixedly mounted on the inner side of the mounting bracket 21, and is used to block the locking block 51;

[0053] The locking pin 55 is fixedly mounted on one side of the rear pillar 22 .

[0054] The specific implementation is as follows: the locking unit 5 is a mechanical locking method. The position of the hydrofoil needs to remain unchanged when the hydrofoil boat is traveling. When the lifting rope 43 pulls the rear hydrofoil 23 upward to drive the rear pillar 22 to move upward, it is necessary to rotate the locking block 51 first to separate it from the locking pin 55. When the locking pin 55 is at the locking block 51, the lifting rope 43 can pull the rear hydrofoil 23 upward to move. The size of the top of the rear pillar 22 is larger than the size of the mounting bracket 21. Therefore, when the driving source 41 drives the winding drum 42 to rotate to release the lifting rope 43, the rear hydrofoil 23 moves downward, and the top of the locking block 51 is in an inclined arc shape. The rear pillar 22 moves downward to drive the locking pin 55 to move downward and drive the top of the locking block 51 to move outward. When the locking pin 55 moves to below the inclined position of the locking block 51, the torsion spring 53 drives the locking block 51 to reset, and the locking pin 55 is stuck. The position of the rear pillar 22 is fixed. The locking principle of the front wing 3 is the same as that of the tail wing 2.

[0055] Embodiment three:

[0056] Please refer to Figure 5 : The rear strut 22 includes a strut side surface 222, a rounded corner 223, and a strut rear surface 224. The strut side surface 222 has a hydrodynamic curve. The strut rear surface 224 is located behind the rear strut 22. The strut rear surface 224 is a plane. There is a rounded corner 223 between the strut rear surface 224 and the strut side surface 222.

[0057] In this embodiment, the rear strut 22 is wider at the front and narrower at the rear. The design of the rear strut 22 not only takes into account the structural strength but also fully considers the hydrodynamic performance. The strut side surface 222 adopts a hydrodynamic curve to reduce the water flow resistance and improve the navigation efficiency. The strut rear surface 224 is designed as a plane, and there is a smooth transition between the strut rear surface 224 and the strut side surface 222 through the rounded corner 223, further reducing eddies and turbulence and lowering energy consumption.

[0058] Embodiment Four:

[0059] Please refer to Figure 6 : The strut rear surface 224 is elliptical.

[0060] In this embodiment, on the basis of Embodiment Three, the strut rear surface 224 is designed to be elliptical. This design further optimizes the hydrodynamic performance, reduces the impact and resistance of the water flow on the strut. Especially when sailing at high speed, it can significantly improve the navigation efficiency and stability of the hydrofoil boat.

[0061] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
