For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] The following is combined with Figure 1 To Attachment Figure 6 , some embodiments of the present invention are described in detail. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0048] A hydrofoil boat comprises a hull 4, a wing plate 2, a rotating strut 3 and a water jet propulsion device 1; the water jet propulsion device 1 is arranged on the hull 4; the wing plate 2 is rotatably arranged on the hull 4 by means of the rotating strut 3, the wing plate is a U-shaped plate, the two ends of the wing plate are respectively connected to the two ends of the rotating strut, and the wing plate can be rotated from the bottom of the hull to the front end or the rear end of the hull.

[0049] When traveling in deep water, the water jet propulsion device 1 serves as the power of the hydrofoil boat and can drive the hull 4 to move. The provision of the wing plate 2 can increase the balance of the hull 4.

[0050] When the hydrofoil boat reaches a shallow beach, the wing plate 2 rotates around the rotating strut 3, thereby driving the rotating strut 3 to rotate upward, thereby reducing the draft of the hull 4, so that the hull 4 can continue to travel on the shallow beach through the water jet propulsion device 1, or continue to travel using oars, and thus the hull 4 can be moved to the shore, which is convenient for people to enter and exit the boat, and also convenient for loading and unloading of goods on the boat.

[0051] In this embodiment, the wing plate 2 is in the shape of a U-shaped plate. Through the U-shaped setting, the two ends of the wing plate 2 are respectively connected to the rotating strut 3, thereby ensuring the balance of the wing plate 2 on the rotating strut 3, and further ensuring the balance of the connection of the wing plate 2 to the hull 4.

[0052] In this embodiment, the cross section of the wing plate 2 is a hydrofoil with a cross section similar to that of a wing, that is, the upper surface of the wing plate is an arc surface, the lower surface of the wing plate is a plane or an arc surface, the area of ​​the upper surface of the wing plate is larger than the area of ​​the lower surface of the wing plate, the upper surface of the hydrofoil is upwardly convex, and the area of ​​the upper surface of the hydrofoil is larger than the area of ​​the lower surface. When the electric water jet propulsion device is running, the boat drives the wing plate forward in the water. Due to the difference in the upper and lower surface areas of the wing plate, the speed of water flowing through the upper surface of the hydrofoil is different from the speed of water flowing through the lower surface, and the speed of water flowing through the upper surface of the hydrofoil is greater than the speed of water flowing through the lower surface. Since the flow velocity of the upper surface of the hydrofoil is greater than the flow velocity of the lower surface, the hydrofoil generates upward buoyancy in the water. Then, the hull is propped up by the wing plate, the contact area between the hull and the water is reduced, the resistance of wind and waves to the hull is reduced, and the boat moves faster.

[0053] In a preferred embodiment of the present invention, specifically, when the wing panel 2 is horizontal, the wing panel 2 is below the hull 4 .

[0054] That is to say, the axis of the rotating strut 3 is not in the width direction of the wing plate 2, but in the thickness direction of the wing plate 2. When the horizontal wing plate is set horizontally, it can have a larger buoyancy, thereby ensuring the stability of the hull 4 during driving.

[0055] In a preferred embodiment of the present invention, there are two rotating struts 3 , which are respectively arranged at two ends of the hull 4 , and wing plates 2 are arranged on both rotating struts 3 .

[0056] There are two rotating struts 3, which are respectively arranged at the front end and the rear end of the hull 4, and the two rotating struts 3 are arranged in parallel. The two wing plates 2 are respectively arranged on the two rotating struts 3. When the hull 4 travels on the shallows, the two wing plates 2 are flipped toward the front and rear ends respectively to achieve the effect of reducing the draft depth.

[0057] In a preferred embodiment of the present invention, a first positioning device is further provided on the hydrofoil boat, and the first positioning device is connected to the rotating strut to position the rotating angle of the wing plate.

[0058] Specifically, in a preferred embodiment of the present invention, the first positioning device includes a first lifting motor 7, a driving gear 8 and a transmission gear 9; the driving gear 8 is coaxially arranged on the motor shaft of the first lifting motor 7, and the transmission gear 9 is coaxially arranged on the rotating support rod 3, and the driving gear 8 is meshed with the transmission gear 9; the wing plate 2 is fixedly arranged on the rotating support rod 3.

[0059] like Figure 5 As shown, specifically, in this embodiment, the first lifting motor 7 is fixedly arranged on the hull 4, the driving gear 8 is coaxially arranged on the motor shaft of the first lifting motor 7, and is coaxially arranged with the motor shaft of the first lifting motor 7, and the transmission gear 9 is coaxially fixedly arranged on the transmission strut, the transmission gear 9 is meshed with the driving gear 8, and the wing panel 2 and the rotating strut 3 are fixedly connected.

[0060] When the first lifting motor 7 rotates forward, it drives the driving gear 8 to rotate forward, further drives the transmission gear 9 to rotate reversely, and then the rotating support rod 3 also rotates reversely, and finally drives the wing panel 2 to rotate reversely, so that the wing panel 2 is flipped to the rear end or the front end, and the wing panel 2 is folded.

[0061] When the first lifting motor 7 rotates in the reverse direction, it drives the driving gear 8 to rotate in the reverse direction, further drives the transmission gear 9 to rotate forward, and then the rotating strut 3 also rotates forward, and finally drives the wing panel 2 to rotate forward, so that the wing panel 2 rotates downward, and the folded wing panel 2 is put down to support the hull 4.

[0062] In a preferred embodiment of the present invention, the hydrofoil boat further comprises a second positioning device, which is respectively connected to the wing plate and the rotating strut, and is used for positioning the rotating angle of the wing plate.

[0063] In a preferred embodiment of the present invention, the positioning device includes multiple groups of positioning marble assemblies; the positioning marble assemblies include a compression spring 13 and a marble body 12; a positioning groove 14 is provided on the side wall of the rotating support rod 3, a rotating hole is provided at the end of the wing plate 2, a sliding groove 11 is provided on the side wall of the rotating hole, and a positioning hole 10 is provided at the bottom of the sliding groove 11; the compression spring 13 is provided in the positioning groove 14, and one end of the compression spring 13 is abutted against the bottom of the positioning groove 14, and the other end is abutted against one side of the marble body 12, and the other side of the marble body 12 is abutted against the bottom of the sliding groove 11, and the marble body 12 can extend outward from the positioning hole 10 under the action of the compression spring 13, so as to realize the positioning of the wing plate 2 on the rotating support rod 3.

[0064] like Figure 6As shown, specifically, in this embodiment, a plurality of groups of positioning marble assemblies are evenly arranged around the rotating support rod 3, or are arranged around the rotating support rod 3 and the intervals between adjacent positioning marble assemblies are the same, or a plurality of groups of positioning marble assemblies are respectively arranged at specific positions to achieve specific angle limiting of the wing plate 2.

[0065] More specifically, a rotating hole is provided at the end of the wing plate 2, the rotating support rod 3 is inserted into the rotating hole, and has a transition or clearance fit with the rotating hole, a sliding groove 11 is provided on the side wall of the rotating hole, the sliding groove 11 extends along the side wall of the rotating hole to form a circle, and a positioning hole 10 is provided at the bottom of the sliding groove 11 for positioning the rotation angle between the rotating support rod 3 and the wing plate 2.

[0066] In this embodiment, a plurality of positioning grooves 14 are provided on the side wall of the rotating support rod 3, and a group of positioning marble assemblies are provided in each positioning groove 14, that is, a compression spring 13 and a marble body 12 are provided in each positioning groove 14, one end of the compression spring 13 is abutted against the bottom of the positioning groove 14, and the other end is abutted against one side of the marble body 12, and the other side of the marble body 12 is abutted against the bottom of the sliding groove 11 under the action of the compression spring 13.

[0067] When the wing plate 2 rotates, all the elliptical bodies 12 slide in the sliding groove 11 under the action of the compression springs 13 that resist each other. When a elliptical body 12 rotates to the position of the positioning hole 10 during the rotation of the wing plate 2, under the action of the compression spring 13, the elliptical body 12 enters the positioning hole 10 away from the side of the compression spring 13 and extends a part of it from the positioning hole 10, that is, a part of the elliptical body 12 is inserted into the positioning hole 10, connecting the wing plate 2 and the rotating support rod 3 together to form a whole, so that the wing plate 2 cannot rotate, thereby realizing the rotation positioning of the wing plate 2.

[0068] When the wing plate 2 needs to continue to rotate, press the marble body 12 extending from the positioning hole 10 to press the marble body 12 back into the sliding groove 11. At this time, the wing plate 2 can continue to rotate until the next marble body 12 extends from the positioning hole 10 to position the rotation angle of the wing plate 2.

[0069] Specifically, in this embodiment, the rotational positioning angle of the wing panel 2 at least includes the angle when the wing panel 2 is horizontally set, and the angle when the wing panel 2 is vertically set, that is, the angle when the wing panel 2 is set directly below the hull 4, and the angle when the wing panel 2 is set at the front end or rear end of the hull 4.

[0070] When the wing plate 2 is arranged at the bottom of the hull 4, it can ensure the balance of the hull 4 to the greatest extent; when the wing plate 2 is arranged at the front end or the rear end of the hull 4, it can reduce the draft depth to the minimum.

[0071] In a preferred embodiment of the present invention, the water jet propulsion device 1 includes a shell, a driving assembly, a driving shaft, a first impeller and a second impeller; a fluid channel and a tank body are provided in the shell, and the fluid channel includes a water inlet and a drain outlet; a pressurization zone is provided in the fluid channel near the drain outlet, and the diameter of the inner wall of the pressurization zone decreases along the drainage direction; the driving shaft is provided inside the shell and connected to the driving assembly; the driving assembly is provided in the tank body, and is used to drive the driving shaft to rotate; the first impeller is fixedly connected to the driving shaft, and the second impeller is rotatably connected to the driving shaft, and the first impeller is located upstream of the second impeller, and the second impeller is located inside the pressurization zone.

[0072] The shell is set to be cylindrical, and the front end (upstream position) and the rear end (downstream position) of the shell are both set to be conical, and a fluid channel and a silo are set in the shell; the fluid channel is used for passing water flow, and the fluid channel includes a water inlet and a drain port; preferably, the water inlet is set at the bottom of the shell, and the drain port is set at one end of the shell in the axial direction; a pressurization zone is set near the drain port in the above-mentioned fluid channel, and the diameter of the inner wall of the pressurization zone decreases along the drainage direction. Since the diameter of the pressurization zone decreases, it can play a role in pressurizing the water flow, thereby increasing the flow rate; the drive shaft is set inside the shell and connected to the drive assembly; the drive assembly is set in the silo, and is used to drive the drive shaft to rotate; the first impeller is fixedly connected to the drive shaft and can rotate synchronously with the drive shaft, and the second impeller is rotatably connected to the drive shaft, so as to rectify the water flow discharged by the first impeller; and the first impeller is located upstream of the second impeller, and the second impeller is located inside the pressurization zone.

[0073] In the underwater propeller of the present application, since a pressurization zone is provided in a position near the drain outlet in the fluid channel in the shell, the diameter of the inner wall of the pressurization zone decreases along the drain direction; the second impeller is located inside the pressurization zone, and the first impeller is located upstream of the second impeller. When the driving assembly drives the first impeller to rotate through the driving shaft, the first impeller propels the water flow into the pressurization zone, and the diameter of the inner wall of the pressurization zone decreases along the drain direction; the second impeller located in the pressurization zone accelerates the water flow and sprays it out of the drain outlet, thereby increasing the propulsion force, thereby enhancing the propulsion power of the underwater propeller and improving the driving effect.

[0074] In a preferred embodiment of the present invention, Figure 7 As shown, the hydrofoil boat also includes a vertical rotating shaft 6 and a rotating motor 15. The rotating motor 15 is arranged on the hull 4. The vertical rotating shaft 6 is rotatably arranged on the hull 4. The rotating motor 15 is connected to one end of the vertical rotating shaft 6. The other end of the vertical rotating shaft 6 is connected to the water jet propulsion device 1, which is used to drive the water jet propulsion device 1 to rotate through the rotating motor 15 to realize the change of direction of the hull 4.

[0075] By setting the vertical rotating shaft 6 and the rotating motor 15, a steering mechanism of the light wing hydrofoil boat is formed, which can make the water jet propulsion device 1 rotate in the horizontal direction, that is, the direction of the rotating shaft is the vertical direction, thereby realizing the change of direction of the hull 4.

[0076] Specifically, the rotating motor 15 is fixedly disposed on the hull 4 , and is connected to one end of the vertical rotating shaft 6 , and can drive the vertical rotating shaft 6 to rotate, while the other end of the vertical rotating shaft 6 is connected to the water jet propulsion device 1 .

[0077] When the rotating motor 15 rotates forward, it drives the vertical rotating shaft 6 to rotate forward, further drives the water jet propeller 1 to rotate forward, and then rotates the water spraying direction of the water jet propeller 1 to the left side of the hull 4, and then sprays water from the rear end of the hull 4 to the left, so that the rear end of the hull 4 rotates around the hull 4 to the right, and finally realizes the left turn of the hull 4; when the rotating motor 15 rotates reversely, it drives the vertical rotating shaft 6 to rotate reversely, further drives the water jet propeller 1 to rotate reversely, and then rotates the water spraying direction of the water jet propeller 1 to the right side of the hull 4, and then sprays water from the rear end of the hull 4 to the right, so that the rear end of the hull 4 rotates around the hull 4 to the left, and finally realizes the right turn of the hull 4.

[0078] In a preferred embodiment of the present invention, the hydrofoil boat also includes a second lifting motor 16 and a swing seat 5; the second lifting motor 16 is arranged on the hull 4, the rotating motor 15 is arranged on the swing seat 5, and the end of the vertical rotating shaft 6 away from the water jet propulsion device 1 is rotatably arranged on the swing seat 5; the second lifting motor 16 is connected to the swing seat 5, and is used to drive the swing seat 5 to rotate, thereby driving the water jet propulsion device 1 to swing upward.

[0079] When the light wing hydrofoil boat is traveling in a shallow beach, its draft is relatively small. At this time, in order to ensure the draft and prevent the water jet propeller 1 from contacting the bottom of the water and causing the hull 4 to run aground, in this embodiment, the water jet propeller 1 is also provided with a flippable structure, that is, it can drive the water jet propeller 1 to flip, raise the horizontal height of the water jet propeller 1, and then reduce the draft of the hull 4, thereby avoiding the hull 4 running aground due to the water jet propeller 1.

[0080] Specifically, in this embodiment, when the second lifting motor 16 rotates forward, it drives the swing seat 5 to rotate forward. At this time, the vertical rotating shaft 6 and the rotating motor 15 rotate forward following the swing seat 5, thereby driving the water jet propulsion device 1 arranged at the lower end of the vertical rotating shaft 6 to rotate forward and upward, thereby realizing the increase in the height of the water jet propulsion device 1.

[0081] When the second lifting motor 16 rotates in the reverse direction, it drives the swing seat 5 to rotate in the reverse direction. At this time, the vertical rotating shaft 6 and the rotating motor 15 rotate in the reverse direction following the swing seat 5, thereby driving the water jet propeller 1 arranged at the lower end of the vertical rotating shaft 6 to rotate in the reverse direction downward, thereby achieving a reduction in the height of the water jet propeller 1 and a lowering of the water jet propeller 1, thereby ensuring the thrust effect of the water jet propeller 1 and the balance of the thrust of the water jet propeller 1.

[0082] Specifically, in the present embodiment, when the water jet propulsion device 1 is being raised in height, the swinging direction thereof is left and right, that is, the water jetting direction of the water jet propulsion device 1 is always kept horizontal, thereby ensuring the moving effect of the hull 4.

[0083] In a preferred embodiment of the present invention, the hydrofoil boat further comprises a controller, which is respectively connected to the positioning device and the water jet propulsion device 1 and is used to control the positioning position of the wing plate 2 and the driving direction and speed of the hull 4.

[0084] Specifically, the controller is connected to the first lifting motor 7, the second lifting motor 16 and the rotating motor 15 by signals, respectively, and controls the rotation angle and rotation speed of the first lifting motor 7, the second lifting motor 16 and the rotating motor 15, respectively, thereby realizing the control of the position of the wing panel 2, the driving direction of the hull 4 and the driving speed of the hull 4.

[0085] More specifically, the controller can be automatic control or manual control.

[0086] The beneficial effects of the embodiments of the present invention are:

[0087] While it provides the hydrofoil boat with moving power through the water jet propulsion, it ensures the balance of the hydrofoil boat on the water surface by setting a horizontal plate-shaped wing under the hull. It can also rotate the wing upward by rotating the strut to reduce the draft of the hydrofoil boat, so that the hydrofoil boat can be driven to the shallows, reducing the manual labor and reducing the labor cost.

[0088] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
