Description

Technical Field

[0001] The present application relates to the technical field of hydrofoil vessels, and in particular to a hydrofoil vessel. Background Art

[0002] A hydrofoil boat is a high-speed boat that uses lifting columns at the bottom of the hull to install hydrofoils. When the speed of the boat increases, the buoyancy provided by the hydrofoil will lift the hull off the water surface, thereby increasing the sailing speed by reducing the resistance of the water. Generally, the hydrofoil of a hydrofoil boat is relatively large and the lifting columns are long, which requires that the hull has sufficient immersion depth when sailing on the wing. However, when the boat is in a moored state, due to the large depth of the hydrofoil and the lifting columns, high requirements are placed on the depth of the water area at the dock. At the same time, if the hydrofoil and the lifting columns are immersed in water for a long time, especially in seawater, it is easy for algae and barnacles to grow on the hydrofoil and the lifting columns, which will corrode the hydrofoil and the lifting columns. Therefore, it is necessary to store the hydrofoil and the lifting columns in the moored state to ensure that they are above the horizontal plane to prevent problems such as rust and reduce the depth requirements for the dock port. The hydrofoils of existing hydrofoil boats are generally not retractable. On the other hand, there are various navigation conditions for hydrofoil vessels during navigation, such as submerged navigation, wing navigation, and wave-resistant wing navigation. Different navigation conditions have different requirements for the immersion depth of the hydrofoil, so the immersion height of the hydrofoil also needs to be adjusted to adapt to different navigation conditions.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0046] The following is attached to the instruction manual Figures 1 to 6 The embodiments of the present application are further described in detail.

[0047] A first exemplary embodiment of the present application provides a hydrofoil vessel, which includes: a hull 1 and at least one lifting mechanism 2 , wherein the at least one lifting mechanism 2 is located on the hull 1 .

[0048] The number of lifting mechanisms 2 can be set according to actual needs. In specific implementation, only one lifting mechanism 2 can be set on the hydrofoil vessel, which can be set at the bow or the stern; two lifting mechanisms 2 can also be set, for example, one lifting mechanism can be set at the bow and the stern respectively, or both can be set at the stern, or both can be set at the bow; three lifting mechanisms 2 can also be set, two of which are set at the bow and one at the stern, or one is set at the bow and two are set at the stern. When two lifting mechanisms 2 are set at the stern, the two lifting mechanisms 2 are symmetrically arranged along the central axis of the hull 1. Similarly, when two lifting mechanisms 2 are set at the bow, the two lifting mechanisms 2 are symmetrically arranged along the central axis of the hull 1. It should be noted that the above lifting mechanism 2 is set at the bow or the stern only for example, not for limiting the position of the lifting mechanism, and the lifting mechanism 2 can also be set at other positions of the hull in the boat.

[0049] The lifting mechanism 2 includes a bracket 24 , a transmission assembly 22 , a lifting column 23 , a driving device 21 , a first turntable 25 , a second turntable 26 , a first traction structure 27 and a second traction structure 28 .

[0050] The bracket 24 is fixedly mounted on the hull 1 by bolts, and the bracket 24 is used to provide support for the transmission assembly 22, the driving device 21, the first turntable 25 and the second turntable 26. In addition, the part of the bracket 24 protruding from the hull 1 is provided with a hollow structure in the vertical direction, and the hollow structure is used to accommodate the lifting column 23.

[0051] The driving device 21 is arranged outside the bracket 24, and the output end of the driving device 21 has an output shaft, which is connected to the transmission assembly 22 through the output shaft. The driving device 21 is used to provide power and transmit the power to the transmission assembly 22, and the transmission assembly 22 further transmits the power to the first rotating disk 25 and the second rotating disk 26 through two paths, driving the first rotating disk 25 and the second rotating disk 26 to rotate.

[0052] One end of the first traction structure 27 is connected to the first turntable 25, and the other end of the first traction structure 27 is connected to the top end of the lifting column 23. One end of the second traction structure 28 is connected to the second turntable 26, and the other end of the second traction structure 28 is connected to the bottom end of the lifting column 23. The rotation of the first turntable 25 can drive the extension or shortening of the first traction structure 27, and the rotation of the second turntable 26 can drive the extension or shortening of the second traction structure 28, thereby driving the lifting column 23 to move up and down through the extension or shortening of the first traction structure 27 and the second traction structure 28.

[0053] The first traction structure 27 and the second traction structure 28 may be transmission belts such as ropes, belts or chains.

[0054] Taking the first traction structure 27 and the second traction structure 28 as ropes for example, the first traction structure 27 is used as a descending rope for descending the lifting column 23, and the second traction structure 28 is used as an ascending rope. One end of the descending rope is fixedly connected to the top of the lifting column 23, and the other end of the descending rope is fixedly connected to the first turntable 25, and the excess rope is wound around the first turntable 25. In actual implementation, a groove for accommodating the rope drum can be provided along the circumference of the first turntable 25, and the excess rope is wound in the groove. The connection between the descending rope and the lifting column 23 and the connection between the descending rope and the first turntable 25 can be connected by a snap connection through a connector. One end of the ascending rope is fixedly connected to the lower end of the lifting column 23, and the other end is fixedly connected to the second turntable 26, and the excess rope is wound around the second turntable 26. Similar to the setting of the first turntable 25, a groove for accommodating the rope drum can be provided along the circumference of the second turntable 26. The connection relationship between the ascending rope and the lifting column 23 and the connection relationship between the ascending rope and the second turntable can be connected by a snap connection through a connector. It is understandable that the winding direction of the descending rope on the first turntable 25 and the winding direction of the ascending rope on the second turntable 26 can be the same or opposite. It is only necessary to set the winding direction so that when the descending rope is shortened, the ascending rope is extended, so as to drive the lifting column 23 to descend; or when the descending rope is extended, the ascending rope is shortened, so as to drive the lifting column 23 to rise.

[0055] In some embodiments, the transmission assembly 22 includes a first transmission element 221, a second transmission element 222 and a third transmission element 223; the axis of the first transmission element 221 is connected to the output end of the driving device 21, and the second transmission element 222 and the third transmission element 223 rotate under the drive of the first transmission element 221, the second transmission element 222 drives the rotation of the first turntable 25, and the third transmission element 223 drives the rotation of the second turntable 26.

[0056] In one embodiment, the first transmission element 221, the second transmission element 222 and the third transmission element 223 are all gears. Specifically, the first transmission element 221 is called the first gear, the second transmission element 222 is called the second gear, and the third transmission element 223 is called the third gear. The axis of the first gear is connected to the output end of the driving device 21, the second gear is meshed with the first gear, and the third gear is meshed with the first gear.

[0057] The first gear is located inside the bracket 24, the output shaft of the driving device 21 extends through the side wall of the bracket 24, and the axis of the first gear is sleeved on the output shaft of the driving device 21. The sleeve arrangement of the first gear and the output shaft of the driving device 21 can be a nested arrangement, that is, there is an aperture at the center of the first gear, and the shape and size of the aperture are the same as the cross-sectional shape and size of the output shaft of the driving device 21. The first gear can also be connected to the output shaft of the driving device 21 through a connecting piece such as a spline, a tapered sleeve, etc. The second gear is meshed with the first gear, and the third gear is meshed with the first gear. The rotation of the first gear can drive the second gear and the third gear to rotate in the same direction.

[0058] The first turntable 25 and the second gear are arranged as coaxial axes, that is, the first turntable 25 and the second gear rotate around the same axis, and the axis of rotation of the first turntable 25 and the second gear is perpendicular to the lifting column 23. The second gear and the first turntable 25 are located on the side away from the hull 1, and the second gear is located on the side close to the driving device 21. The second gear is rotatably connected to the bracket 24 through a connecting member; the first turntable 25 is located on the side away from the driving device 21, and is rotatably connected to the bracket 24 through a connecting member. The second gear is connected to the first turntable 25, and there is no relative displacement between the second gear and the first turntable 25, so that the second gear can drive the first turntable 25 to rotate.

[0059] The second turntable 26 and the third gear are arranged as coaxial axes, that is, the second turntable 26 and the third gear rotate around the same axis, and the axis of rotation of the second turntable 26 and the third gear is perpendicular to the lifting column 23. The second turntable 26 and the third gear are located on the side away from the hull 1. The third gear and the second gear are located in the same vertical plane, and the second turntable 26 and the first turntable 25 are located in the same vertical plane. The third gear is connected to the second turntable 26, and there is no relative displacement between the third gear and the second turntable 26, so that the third gear can drive the second turntable 26 to rotate.

[0060] It can be understood that the driving device 21 provides power and drives the first gear to rotate. Since the first gear is meshed with the second gear and the third gear respectively, the first gear, as the driving gear, transmits power to the second gear and the third gear as the driven gear through meshing, driving the rotation of the second gear and the third gear, and then the second gear drives the first turntable to rotate, and the third gear drives the second turntable to rotate. The first turntable drives the extension or shortening of the first traction structure, and the second turntable drives the shortening or elongation of the first traction structure to achieve the rise or fall of the lifting column. As described above, the same driving device controls the rise or fall in two directions. At the same time, the design of double turntables can avoid problems such as overlapping and crossing of the traction device when the lifting height is too large, if there are many winding circles on the same turntable, and the length of the contraction and extension of the two traction structures in the rise and fall is not matched due to the different winding positions from the center and the different number of winding layers, which makes it easier to cross and overlap.

[0061] In another embodiment, the first transmission element 221 is a worm, the second transmission element 222 is a worm wheel (referred to as the first worm wheel), and the third transmission element 223 is a worm wheel (referred to as the second worm wheel). One end of the worm is connected to the output end of the driving device 21, and the first worm wheel and the second worm wheel are respectively meshed and connected with the worm. The first worm wheel and the first turntable 25 are arranged with coaxial axes, that is, they rotate around the same axis, and the axis around which the first worm wheel and the first turntable 25 rotate is perpendicular to the lifting column 23. The axis of the first worm wheel is connected to the axis position of the first turntable 25 to ensure that there is no relative displacement between the two. The second worm wheel and the second turntable 26 are arranged with coaxial axes, that is, they rotate around the same axis, and the axis around which the second worm wheel and the second turntable 26 rotate is perpendicular to the lifting column 23. The axis of the second worm wheel and the axis of the second turntable 26 are connected to ensure that there is no relative displacement between the two.

[0062] It can be understood that the driving device 21 provides power and drives the worm to rotate, and the worm transmits power to the first worm wheel and the second worm wheel, driving the first worm wheel and the second worm wheel to rotate, and then the first worm wheel drives the first rotating disk 25 to rotate, and the second worm wheel drives the second rotating disk 26 to rotate. The rotation of the first rotating disk 25 causes the first traction structure 27 to be wound (shortened) or loosened (extended) on the first rotating disk 25, and the rotation of the second rotating disk 26 causes the second traction structure 28 to be loosened (extended) or wound (shortened) on the second rotating disk 26, so as to achieve the traction of the lifting column 23 to be lifted and lowered.

[0063] In one embodiment, the bracket 24 includes a first transverse axis 241 and a second transverse axis 242 . Both ends of the first transverse axis 241 pass through the bracket 24 , and both ends of the second transverse axis 242 pass through the bracket 24 .

[0064] In actual implementation, when the first transmission element 221, the second transmission element 222 and the third transmission element 223 are respectively the first gear, the second gear and the third gear, the second gear and the first turntable 25 are sleeved on the first transverse axis 241, the second gear is located on the side close to the drive device 21, and the first turntable 25 is located on the other side. The sleeve mode of the second gear and the first turntable 25 and the first transverse axis 241 is a nested mode, that is, the center of the second gear and the first turntable 25 is provided with an aperture matching the first transverse axis 241. The side of the second gear and the first turntable 25 close to each other is fixedly connected so that there is no relative movement between the two. The fixing mode of the second gear and the first turntable 25 can be a welding mode, that is, the surfaces of the second gear and the first turntable 25 close to each other are welded and fixed. It can also be connected by screws. This embodiment does not limit the fixing mode of the second gear and the first turntable 25. The third gear and the second turntable 26 are sleeved on the second transverse axis 242, the third gear is located on the side close to the drive device 21, and the second turntable 26 is located on the other side. The third gear and the second turntable 26 are nested with the second transverse axis 242, that is, the center of the third gear and the second turntable 26 is provided with an aperture matching the second turntable 26. The third gear and the second turntable 26 are fixedly connected to the opposite sides so that there is no relative movement between the two. The third gear and the second turntable 26 can be fixed by welding, that is, the surfaces of the third gear and the second turntable 26 close to each other are welded and fixed. Screws can also be used for connection. This embodiment does not limit the fixing method of the third gear and the second turntable 26. By setting two transverse axes, the power of the driving mechanism can be more stably transmitted to the two turntables, and the lifting column 23 can be further stably driven to rise and fall smoothly.

[0065] In another embodiment, when the first transmission element 221, the second transmission element 222 and the third transmission element 223 are respectively a worm, a first worm wheel and a second worm wheel, the first worm wheel and the first turntable 25 are mounted on the first horizontal axis 241, and the second worm wheel and the second turntable 26 are mounted on the second horizontal axis 242.

[0066] In one embodiment, the hydrofoil boat further includes a transmission mechanism 32, which is located on a side surface perpendicular to the hull 1, and the input end of the transmission mechanism 32 is connected to the output end of the driving device 21, and the output shaft of the transmission mechanism 32 is connected to the transmission assembly 22. The transmission mechanism 32 can transfer the power generated by the driving device 21 to the transmission assembly 22 after certain adjustments, so that the power transferred to the transmission assembly 22 is more stable, thereby ensuring the stability of the lifting process of the lifting column 23.

[0067] In one embodiment, the transmission mechanism 32 is a planetary reducer with a deceleration torque amplification function, thereby achieving the effect of reducing the rotation speed and increasing the output torque.

[0068] In another embodiment, the transmission mechanism 32 is a worm gear self-locking transmission structure, which can achieve self-locking stop at any position to prevent the lifting column 23 from falling when the power is off.

[0069] In one embodiment, a first fixing member 232 is provided at the upper end of the lifting column 23, and a second fixing member 233 is provided at the lower end of the lifting column 23; one end of the first traction structure 27 is fixed to the first fixing member 232, the other end of the first traction structure 27 is fixedly connected to the first turntable 25, and the excess traction structure is wound around the first turntable 25; one end of the second traction structure 28 is fixedly connected to the second fixing member, the other end of the second traction structure 28 is fixedly connected to the second turntable 26, and the excess traction structure is wound around the second turntable 26. In actual implementation, a blocking block 231 may also be provided at the upper end of the lifting column 23 to prevent the lifting column 23 from falling off the bracket 24 during the lifting process.

[0070] In one embodiment, at least one guide wheel 29 is installed on the side of the bracket 24 close to the hull 1 and the same number of at least one guide wheel 29 is installed on the side away from the hull 1. The guide wheels 29 are rotatably connected to the bracket 24 through a connecting piece. The axial direction of the guide wheels 29 is perpendicular to the bracket 24, and the guide wheels 29 are rollingly connected to the lifting column 23. It should be noted that the guide wheels 29 on the side close to the hull 1 and the guide wheels 29 on the side away from the hull 1 can be installed symmetrically or asymmetrically. The guide wheels 29 can convert the sliding friction of the lifting column 23 during the rising and falling process into rolling friction, effectively reducing the resistance of the lifting column 23 during the lifting process.

[0071] In one embodiment, two guide wheels 29 are installed on the side of the bracket 24 close to the hull 1, respectively located at the upper end and the lower end of the same vertical plane, and two guide wheels 29 are installed on the side away from the hull 1, and the two guide wheels 29 are located at the upper end and the lower end of the same vertical plane. The four guide wheels 29 are all rotatably connected to the bracket 24 and rollingly connected to the lifting column 23. Preferably, the two guide wheels 29 on the side close to the hull 1 and the two guide wheels 29 on the side away from the hull 1 are installed in a symmetrical form.

[0072] The setting of the guide wheel 29 can limit the shaking amount of the lifting column 23 during the lifting process, thereby making the lifting process more stable.

[0073] In one embodiment, considering that the traction device is wound around the turntable too many times, the left and right swing range of the traction device will also increase. Therefore, the outer circumference of the two guide wheels 29 on the side away from the hull 1 is provided with guide wheels with grooves, and the grooves of the guide wheels 29 are used to limit the traction device. Specifically, the guide wheel 29 at the upper end limits the first traction structure 27, and the guide wheel 29 at the lower end limits the second traction structure 28. The grooves can guide the traction device to move along a specific path, reducing the deviation during the ascent and descent process.

[0074] In one embodiment, when the lifting mechanism 2 is arranged at the stern, an inverted L-shaped structure is arranged on the side of the bracket 24 close to the hull 1, and the inverted L-shaped structure is clamped on the hull 1 to be fixedly connected to the hull 1. This makes the connection between the lifting mechanism 2 and the hull 1 more stable. The bracket 24 can be fixed to the hull 1 by screws and bolts.

[0075] In one embodiment, when the lifting mechanism 2 is arranged at the bow, a beveled surface structure is arranged on one side of the bracket 24 close to the hull 1, and the bracket 24 is fixedly connected to the hull 1 through the beveled surface structure. The bracket 24 can be fixed to the hull 1 by screws and bolts.

[0076] In one embodiment, the hydrofoil boat further comprises a propulsion device 30 or a hydrofoil 31, and the propulsion device 30 or the hydrofoil 31 is connected to the bottom end of the lifting column 23. The lifting column 23 drives the propulsion device 30 or the hydrofoil 31 to rise and fall.

[0077] In one embodiment, the propulsion device 30 is a propeller propeller, which includes a propeller and a drive motor connected to the propeller. The drive motor provides electricity to drive the propeller to rotate, and the interaction between the propeller and water generates thrust to propel the hydrofoil craft forward.

[0078] In one embodiment, the angle between the hydrofoil and the horizontal plane is 0 to 5 degrees. That is, the angle of attack of the hydrofoil (the angle between the line connecting the trailing edge and the leading edge of the hydrofoil and the horizontal line) is 0 to 5 degrees, at which time the hydrofoil can generate sufficient lift to support the hull 1 while maintaining low resistance. The hydrofoil 31 is clamped at the lower end of the lifting column 23, and a U-shaped opening matching the shape of the lifting column 23 is provided in the middle of the hydrofoil 31. The hydrofoil 31 is clamped with the lifting column 23 through the U-shaped opening and fixed by screws or welding.

[0079] In one embodiment, the hydrofoil 31 is in the shape of a straight line or a dovetail. The straight line or dovetail hydrofoil design helps to maintain the heading stability.

[0080] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0081] Those skilled in the art can clearly understand that for the convenience and simplicity of description, only the division of the above-mentioned functional units and modules is used as an example. In actual applications, the above-mentioned functions can be distributed and completed by different functional units and modules as needed, that is, the internal structure of the system described in the present application is divided into different functional units or modules to complete all or part of the functions described above.
