Description

Technical Field

[0001] This invention relates to the field of hydrofoil technology, and more specifically, to a ring-shaped hydrofoil and its power system. Background Technology

[0002] Currently, hydrofoils are special vessels designed based on hydrodynamics. During operation, hydrofoils utilize the lift generated by the high-speed movement of hydrofoils in the water to lift the hull off the water surface and achieve high-speed operation.

[0003] In existing technologies, electric hydrofoils suffer from difficulty in autonomously controlling their altitude during propulsion due to lift. Users often fail to notice excessive hydrofoil elevation, which can cause the underwater propeller to emerge from the water, leading to loss of power and balance, and ultimately, a fall into the water. Furthermore, the sharp wingtips of electric hydrofoils can easily injure riders. Summary of the Invention

[0004] To address this, the present invention provides a ring-shaped hydrofoil and its power assembly to solve the technical problems in the prior art where electric hydrofoils are difficult to control autonomously during flight due to lift, and where sharp wingtips can easily scratch riders, resulting in low overall controllability and safety.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A ring-shaped hydrofoil and its power system include a first wing plate, a second wing plate, and two sets of side fins disposed between the first wing plate and the second wing plate; the two ends of the first wing plate and the two ends of the second wing plate are integrally and fixedly connected by the two sets of side fins, and the first wing plate, the second wing plate, and the two sets of side fins form a closed ring structure.

[0007] Based on the above technical solution, the present invention is further described as follows:

[0008] As a further embodiment of the present invention, the second wing plate is located on the upper side of the first wing plate.

[0009] As a further aspect of the present invention, at least one connecting rod is integrally provided between the first wing plate and the second wing plate.

[0010] As a further aspect of the invention, the hydrofoil also has a forward direction.

[0011] The second wing plate is disposed on the front side relative to the first wing plate along the forward direction, and the first wing plate is disposed on the rear side relative to the second wing plate along the forward direction.

[0012] A ring-shaped hydrofoil power assembly includes the ring-shaped hydrofoil and an underwater power unit.

[0013] The underwater propulsion unit and the annular hydrofoil are connected by a transmission mechanism.

[0014] As a further aspect of the present invention, the underwater propulsion unit has a propulsion direction.

[0015] The annular hydrofoil drive is fixed to the front end and / or rear end of the underwater power unit along the power direction.

[0016] As a further aspect of the present invention, the underwater propulsion unit has a propulsion direction.

[0017] The first wing plate and / or the second wing plate are connected in a phase-transmission fixed connection to the underwater power unit.

[0018] As a further embodiment of the present invention, the second wing plate is located at the front side of the underwater propulsion unit along the propulsion direction, and the first wing plate is located at the rear side of the underwater propulsion unit along the propulsion direction.

[0019] As a further embodiment of the present invention, the second wing plate and the first wing plate are respectively located on the upper and lower sides or the lower upper side of the underwater power unit.

[0020] As a further embodiment of the present invention, the second wing plate is located on the upper front side of the underwater power unit along the power direction, and the first wing plate is located on the lower tail side of the underwater power unit along the power direction.

[0021] Alternatively, the second wingplate is located on the lower front side of the underwater propulsion unit along the propulsion direction, and the first wingplate is located on the upper tail side of the underwater propulsion unit along the propulsion direction.

[0022] The present invention has the following beneficial effects:

[0023] 1. This device, by setting up a first wing plate and a second wing plate, when the wing plate is lifted by the lift force and drives the propeller to rise to near the water surface during navigation, the second wing plate surface will emerge from the water first, causing the whole to lose part of the lift force, thereby breaking the force balance of the original navigation state, causing the hydrofoil to descend as a whole, and thus keeping the propeller underwater to continuously provide power, thereby improving the overall functionality and practicality.

[0024] 2. The entire hydrofoil is a closed ring. Since the ring hydrofoil has no tip, it is safer than traditional hydrofoils and effectively reduces the risk.

[0025] 3. During navigation, the side fins will block the vortices flowing from the high-pressure side to the low-pressure side of the first and second fins, which will reduce the lift loss caused by the vortices to a certain extent and improve the overall functional efficiency.

[0036] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] The terms "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0038] Example 1

[0039] like Figure 1 As shown, an embodiment of the present invention provides an annular hydrofoil, including a first wing plate 1, a second wing plate 2, and a side fin plate 3 disposed between the first wing plate 1 and the second wing plate 2.

[0040] Specifically, the side fins 3 are provided in two sets, and the second wing plate 2 is located on the upper side of the first wing plate 1. The two ends of the first wing plate 1 and the two ends of the second wing plate 2 are connected one-to-one by the two sets of side fins 3 to make the entire hydrofoil a closed ring. Since the ring hydrofoil has no tip, it is safer than traditional hydrofoils and effectively reduces the danger. At the same time, by setting the first wing plate 1 and the second wing plate 2, when the wing plate is lifted by the lift and drives the propeller to rise to near the water surface during navigation, the surface of the second wing plate 2 will emerge from the water first, causing the whole to lose some lift, thereby breaking the force balance of the original navigation state, causing the hydrofoil to descend as a whole, and thus keeping the propeller underwater to continuously provide power. In addition, during navigation, the side fins 3 will also block the vortex flow from the high-pressure side to the low-pressure side of the first wing plate 1 and the second wing plate 2, which will reduce the lift loss caused by the vortex to a certain extent and improve the overall functional efficiency.

[0041] As a preferred embodiment, please refer to Figure 2 At least one flat, streamlined connecting rod 4 is integrally fixed between the first wing plate 1 and the second wing plate 2 to strengthen the structural strength between the first wing plate 1 and the second wing plate 2 and improve the functional stability of the overall structure.

[0042] like Figures 3 to 4 As shown, this embodiment of the invention also provides an annular hydrofoil powertrain, including the aforementioned annular hydrofoil, an underwater power unit 5, and a tail fin 6. The underwater power unit 5 has a power direction, the tail fin 6 is driven and fixedly connected to the tail end of the underwater power unit 5 along the power direction, and the annular hydrofoil is driven and fixedly connected to the front end of the underwater power unit 5 along the power direction, thereby realizing a powertrain that uses the annular hydrofoil structure as the forewing.

[0043] Example 2

[0044] In Example 2, the same symbols are used for the same structures as in Example 1, and the same descriptions are omitted. The difference between Example 2 and Example 1 is as follows: Figures 5 to 7As shown, this embodiment of the invention provides another annular hydrofoil power assembly, wherein the first wing plate 1 and / or the second wing plate 2 are connected to the underwater power unit 5 in a phase-transmission fixed connection, and the second wing plate 2 is located at the front side of the underwater power unit 5 along the power direction, and the first wing plate 1 is located at the rear side of the underwater power unit 5 along the power direction.

[0045] The second wing plate 2 and the first wing plate 1 are respectively located on the upper and lower sides or the lower upper side of the underwater power unit 5. Specifically, the second wing plate 2 is located on the upper front side of the underwater power unit 5 along the power direction, and the first wing plate 1 is located on the lower tail side of the underwater power unit 5 along the power direction; or, the second wing plate 2 is located on the lower front side of the underwater power unit 5 along the power direction, and the first wing plate 1 is located on the upper tail side of the underwater power unit 5 along the power direction. This serves as the front wing of the power assembly via the second wing plate 2 of the annular hydrofoil, and the tail wing of the power assembly via the first wing plate 1 of the annular hydrofoil.

[0046] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
