[0002] A motor yacht is a high-end durable consumer product for water entertainment. It integrates functions such as sailing, sports, entertainment, and leisure to meet the needs of individuals and families to enjoy life.
[0003] However, in complex sea conditions, strong winds and waves can bring lateral thrust to the ship, causing the hull to tilt; traditional solutions include timely adjusting the bow direction, reducing speed, adjusting the rudder angle, etc. to increase stability.
[0004] The wing is an extended structure located on the side of the motor yacht hull, similar to the wing of an airplane. They are usually designed with a streamlined shape and are connected to the motor yacht hull and fixed to the side of the hull through a support and connection system. The main function of the wing is to increase lateral stability and reduce roll and sway during sailing.
[0005] A hydrofoil is a design feature of a watercraft or aircraft that provides lift and stability by adding a horizontal or vertical airfoil structure under the hull of a ship or outside the wing of an aircraft. The main principle of a hydrofoil is to use the lift generated by water or air flowing over the airfoil structure to improve the performance of a ship or aircraft.
[0006] Based on this, there is a need for a power yacht with improved hull stability, which can achieve good anti-roll and anti-tilt effects under a range of complex sea conditions through the design of side wings and hydrofoils. Utility Model Content

[0029] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.
[0030] The following describes the implementation methods of the present invention through specific concrete examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The present invention can also be implemented or applied through other different specific implementation methods, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0031] In order to enhance the stability of the hull 1 and reduce the roll, the motor yachts in the prior art all use the motor yachts with the side wing 21 structure, and the lift of the side wing 21 reduces the resistance of the hull 1 to the water body. However, under different sea conditions, the resistance brought by the side wing 21 itself may be greater than the resistance reduced by the lift, which increases the resistance of the motor yacht and increases the energy consumption. Under this premise, how to use only the adjustable side wing 21 structure to reduce energy consumption and cost has become an urgent problem to be solved in the industry.
[0032] Based on this, the embodiment of this specification proposes a solution for the wing 21: this solution only uses the adjustment mechanism 5 to adjust the angle of attack of the wing 21.
[0033] like Figure 1 As shown, an embodiment of the present application provides a power yacht for improving hull stability, including a hull 1, a power device 4, a hydrofoil assembly 2, and a tail wing assembly 3 arranged on the stern of the hull 1; the hydrofoil assembly 2 includes side wings 21 and fixing parts thereof, and the side wings 21 are fixed to both sides of the hull 1 through the fixing parts; the side wings 21 are arranged obliquely relative to the water surface.
[0034] In this solution, the structural design of the tail assembly 3 and the hydrofoil assembly 2 can significantly improve the maneuverability of the power yacht. The tail assembly 3 is similar to the horizontal tail assembly 3 of an aircraft, which can provide additional lift on the water surface to help adjust the attitude and heading of the power yacht. The hydrofoil assembly 2 increases the lateral stability of the power yacht and reduces the impact of side winds and side waves on the power yacht. This combination makes the power yacht more flexible and easy to control when turning, avoiding obstacles or dealing with complex sea conditions; at the same time, the tail assembly 3 reduces the contact area between the power yacht hull 1 and the water surface by generating lift, thereby reducing friction resistance; the hydrofoil assembly 2 reduces roll and roll, allowing the power yacht to travel more smoothly and reducing hydrodynamic resistance; the power yacht can sail at a higher speed with the same power input, or maintain the same speed with lower power consumption, thereby saving fuel costs and reducing the impact on the environment.
[0035] It should be pointed out that Figure 1 The number of the side wings 21 shown in the figure is 2, but in actual application, more than 2 side wings 21 can be provided to further enhance the stability of the motor yacht; Figure 1 The installation position and specifications of the side wings 21 shown in the figure are only preferred. In actual application, the specifications and installation position of the side wings 21 can be adjusted according to environmental factors such as sea conditions.
[0036] In a preferred embodiment, the cross section of the wing 21 is streamlined.
[0037] In this solution, the design of the streamlined cross section can reduce the turbulence and eddy currents generated when the side wing 21 moves, making the side wing 21 more stable, helping to ensure that the side wing 21 maintains a good working condition under various sailing conditions and improving the overall stability of the power yacht.
[0038] It should be pointed out that Figure 1 The shape of the wing 21 shown in the figure is only preferred. In actual application, the streamlined structure of the wing 21 can be adjusted according to environmental factors such as sea conditions.
[0039] In a preferred embodiment, the fixing portion is a detachable structure, and the side wing 21 is detachably connected to the hull 1 through the fixing portion.
[0040] In this solution, the detachable side wings 21 design allows the power yacht to choose whether to install the side wings 21 as needed; when a higher speed or better maneuverability is required, the side wings 21 can be installed; when a simpler driving or sailing in narrow waters is required, the side wings 21 can be removed, increasing the flexibility and versatility of the power yacht; at the same time, the detachable side wings 21 can be easily unloaded and stored, saving transportation space and storage space. This is particularly important for power yachts that need to be frequently transferred between different waters, which can reduce transportation costs and reduce the demand for storage facilities.
[0041] Furthermore, the detachable wing 21 makes maintenance and repair work more convenient; if the wing 21 needs to be maintained or repaired, it can be easily disassembled and necessary work can be carried out without large-scale repair of the entire motor yacht; the detachable wing 21 design allows the motor yacht to be adjusted according to different sailing conditions and uses; when long-distance sailing or sea cruising is required, the wing 21 can be installed to improve stability and efficiency; when sailing in shallow water or docking, the wing 21 can be disassembled to reduce the water depth requirement and increase the flexibility of the hull 1; the detachable wing 21 design can also improve the appearance design of the motor yacht. When the wing 21 is not in use, the motor yacht can present a more concise and elegant appearance, and when necessary, the wing 21 can be installed to increase the dynamic and technological sense of the motor yacht.
[0042] In a preferred embodiment, the motor yacht further comprises two adjusting mechanisms 5 ; the side wing 21 is connected to the adjusting mechanism 5 , and the adjusting mechanism 5 can adjust the angle of attack of the side wing 21 .
[0043] In this solution, the adjustable wing 21 can be adjusted according to different sailing conditions and requirements, thereby improving the maneuverability of the power yacht. By adjusting the angle or position of the wing 21, the attitude and heading of the power yacht can be adjusted, making it easier to drive and control, especially when turning a curve or sailing at a variable speed.
[0044] It should be noted that the number of the adjustment mechanisms 5 should be equal to the number of the side wings 21, so Figure 1-Figure 3 The number of the adjusting mechanisms 5 of the medium-powered yacht is 2; when the number of the side wings 21 is multiple, the number of the adjusting mechanisms 5 should be set to be equal to the side wings 21.
[0045] In a preferred embodiment, the adjustment mechanism 5 includes a motor, a gear, an adapter block 53, an input shaft 51 and an output shaft 52; the motor is connected to the input shaft 51 to drive the output shaft 52 to rotate; the output shaft 52 is connected to the adapter block 53, and the side wing 21 is fixed at the adapter block 53; the angle adjustment of the side wing 21 is achieved by rotating the output shaft 52 and thereby driving the adapter block 53 to rotate.
[0046] In this solution, the adapter block 53 is designed to allow the wing 21 to rotate independently of the hull 1 without causing conflict with the hull 1; specifically, a hole is opened in the hull 1 to allow the output shaft 52 to extend and connect to the adapter block 53, and the wing 21 is rotated by rotating the adapter block 53 without affecting the hull 1.
[0047] Furthermore, the adjustment mechanism 5 can also be connected to an automatic control system, and the angle of attack of the wing 21 can be automatically adjusted through the environmental variables obtained by the automatic control system; the automatic control system can continuously monitor environmental variables, such as wind speed, wave height, water flow, etc., and adjust the angle of attack of the wing 21 according to real-time data; the power yacht can maintain optimal performance under different sea conditions and sailing conditions to ensure the safety and comfort of sailing; the automatic control system can automatically adjust the angle of attack of the wing 21 according to different sailing environments and conditions, and has strong adaptability and flexibility. Whether facing strong winds, big waves, complex water flow or other different environmental factors, the power yacht can adapt to and maintain a good sailing state by automatically adjusting the angle of attack of the wing 21.
[0048] In a preferred embodiment, the hydrofoil assembly 2 further includes a hydrofoil 22 disposed on the bottom of the ship.
[0049] In this solution, the design of the hydrofoil 22 can reduce the frictional resistance of the water surface, so that the hull 1 can sail at a higher speed; by generating lift underwater, the hydrofoil 22 can lift the hull 1 above the water surface, reducing the contact between the hull 1 and the water, thereby reducing frictional resistance and improving navigation speed and efficiency.
[0050] In a preferred embodiment, Figure 6 As shown, the hydrofoil 22 is a symmetrical wing-shaped hydrofoil, and the cross-sectional shape of the hydrofoil 22 is similar to a symmetrical wing, such as an elliptical or trapezoidal wing of an aircraft; a symmetrical wing-shaped hydrofoil generally has a higher lift coefficient and a lower drag.
[0051] In a preferred embodiment, two groups of hydrofoils 22 are provided, and the two groups of hydrofoils 22 are respectively arranged on the front and rear sides of the bottom of the ship.
[0052] In this solution, the front hydrofoil 22 and the rear hydrofoil 22 can be distributed in front and behind the hull 1 to provide a wider support area, thereby reducing the roll and rolling of the hull 1 and making the hull 1 more stable, especially in the face of sea conditions with strong winds and waves.
[0053] Furthermore, three or more hydrofoils 22 may be provided on the bottom of the boat to further enhance the stability of the motor yacht; however, in actual applications, considering factors such as energy consumption, it is not advisable to provide too many hydrofoils 22, and the number of hydrofoils 22 may be reasonably set according to actual use requirements.
[0054] In addition, under the spirit of the utility model of the utility model, the specific embodiment of the power yacht of the utility model can also add new variations on the basis of the above embodiments, for example: the hull 1 can be provided with no side wings 21, but only with the tail wing assembly 3 and the hydrofoil 22. The other components and the connection methods between the components are the same as the above embodiments of the utility model, and will not be repeated here due to space reasons. However, it should be understood that these components and the connection methods between the components can be introduced into the variation as equivalent embodiments.
[0055] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
