Description

Technical Field

[0001] This utility model relates to the field of marine equipment technology, and in particular to a wave-suppressing device and a boat. Background Technology

[0002] When a boat travels at high speed, it is prone to violent pitching and rolling due to the wind and waves. In severe cases, the bow may bounce violently or even lift up and capsize, which has an adverse effect on the comfort and safety of the boat.

[0003] To address these issues, wave-suppressing devices are often used in the high-speed boat industry to reduce the hull's pitching and rolling, thereby reducing bow bounce and allowing the boat to navigate in a relatively stable manner. Wave-suppressing devices primarily adjust attitude parameters such as pitch and roll by altering the water pressure distribution at the stern or bottom of the hull.

[0004] Existing wave-damping devices generally include a drive structure and flow-blocking plates. The drive structure moves the flow-blocking plates to change their angle in the water. However, existing wave-damping devices typically use reciprocating structures such as electric actuators or hydraulic cylinders as the drive structure. These reciprocating structures require forced reversal when they reach their travel limits. Due to mechanical inertia and control delay, "overshoot" is prone to occur. That is, the moving parts exceed their limit positions and impact the mechanical structure, leading to increased vibration, noise, and component wear. This also affects the accuracy of attitude control and may even cause the flow-blocking plates to go out of control due to overshoot.

[0005] Therefore, the above problems urgently need to be solved. Utility Model Content

[0006] The purpose of this invention is to provide a wave-damping device and a boat to avoid the "overshoot phenomenon" of traditional reciprocating motion, thereby eliminating the vibration, wear and control deviation problems caused by overshoot in principle.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] A wave-suppressing device includes a six-bar linkage, a flow-blocking plate, and a rotary drive component. The rotary drive component drives the flow-blocking plate to rotate via the six-bar linkage, so that the flow-blocking plate has a working position that extends into the water.

[0009] The hinged six-bar linkage includes a frame, a first link, a second link, a third link, a fourth link, and a fifth link, wherein:

[0010] The frame is used to fix the wave-suppressing device to the stern of the hull. The first link, the third link, and the fifth link are respectively hinged to the frame. The fourth link is respectively hinged to the third link and the fifth link. One end of the second link is hinged to the first link, and the other end is hinged to the third link and / or the fourth link.

[0011] The rotary drive component is fixedly installed on the frame. The rotary drive component is used to drive the first link to rotate, and to drive the third link and the fifth link to swing through the second link.

[0012] The flow-blocking plate is located at the end of the fifth link away from the frame, and the flow-blocking plate can be inserted into or removed from the water surface as the fifth link swings.

[0013] Preferably, when the fifth link swings down to the lowest point, the third link and the fourth link are collinear, and the first link (12) and the second link (13) are collinear, so that the six-bar linkage forms a dead point.

[0014] Preferably, the wave-suppressing device further includes a control component and an angle sensor. The angle sensor and the rotary drive component are both electrically connected to the control component. The angle sensor is configured to detect the rotation angle of the first connecting rod and feed the detection result back to the control component. The control component controls the rotary drive component to operate according to the feedback signal from the angle sensor, so as to regulate the rotation angle of the flow-blocking plate.

[0015] Preferably, the wave-damping device further includes a posture sensor configured to detect the posture of the hull during navigation and feed the detection result back to the control unit. The control unit controls the rotation drive to operate based on the feedback signal from the posture sensor, so as to adjust the posture of the hull during navigation by regulating the rotation angle of the flow-damping plate.

[0016] Preferably, the fifth link and the flow-blocking plate are arranged at an angle, so that the flow-blocking plate extends downward on the side away from the fifth link.

[0017] A vessel, the vessel comprising a hull and the aforementioned wave-damping device, the wave-damping device being disposed at the stern of the hull.

[0018] Preferably, two wave-suppressing devices are provided, and the wave-suppressing devices are distributed on both sides of the hull's forward direction.

[0019] The beneficial effects of this utility model are:

[0020] This invention employs a continuous rotation drive for the rotating component. Through the hinged transmission between the connecting rod and the baffle plate, the swing angle of the baffle plate is naturally limited by the rotation range of the rotating component. There is no need to set a rigid stroke end, allowing the rotating drive component to rotate continuously without reversing direction. This avoids the "overshoot phenomenon" of traditional reciprocating motion and eliminates the vibration, wear, and control deviation problems caused by overshoot in principle.

Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0032] In this application, the term "and / or" describes a relationship between related objects, indicating that three relationships can exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent: the existence of only one centrifugal vortex magnetic pump, the simultaneous existence of one centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump, or the existence of only one centrifugal vortex magnetic pump. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints.

Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0035] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts.

[0037] Please see Figures 1 to 5 This embodiment provides a wave-suppressing device, which includes a hinged six-bar linkage 1, a flow-blocking plate 2, and a rotary drive 3. The rotary drive 3 drives the flow-blocking plate 2 to rotate through the hinged six-bar linkage 1, so that the flow-blocking plate 2 has a working position that extends into the water.

[0038] Specifically, the hinged six-bar linkage 1 includes a frame 11, a first link 12, a second link 13, a third link 14, a fourth link 15, and a fifth link 16. The frame 11 is used to fix the wave-damping device to the stern of the hull 10. The first link 12, third link 14, and fifth link 16 are hinged to the frame 11, and the fourth link 15 is hinged to both the third link 14 and the fifth link 16. One end of the second link 13 is hinged to the first link 12, and the other end is hinged to the third link 14 and / or the fourth link 15. A rotary drive 3 is fixedly mounted on the frame 11. The rotary drive 3 drives the first link 12 to rotate and drives the third link 14 and the fifth link 16 to swing via the second link 13. A flow-blocking plate 2 is disposed at the end of the fifth link 16 away from the frame 11. The flow-blocking plate 2 can be inserted into or removed from the water surface as the fifth link 16 swings.

[0039] With this configuration, the first connecting rod 12 is continuously rotated by the rotary drive 3, and the fourth connecting rod 15 converts the circular motion of the first connecting rod 12 into the reciprocating oscillation of the baffle plate 2. Specifically, the rotation center of the first connecting rod 12 and the hinge point of the fourth connecting rod 15 form an eccentricity, causing the first connecting rod 12 to rotate and drive the fourth connecting rod 15 to perform reciprocating linear motion, thereby pulling or pushing the baffle plate 2 to rotate around the fulcrum of the frame 11, changing the water entry angle and depth of the baffle plate 2, and suppressing pitching and rolling by adjusting the water pressure distribution at the stern of the hull 10. It can be understood that by using the continuous rotation drive of the first connecting rod 12, and through the hinge transmission between the fourth connecting rod 15 and the baffle plate 2, the oscillation angle of the baffle plate 2 is naturally limited by the rotation range of the first connecting rod 12. There is no need to set a rigid stroke end, allowing the rotary drive 3 to rotate continuously without reversing direction, avoiding the "overshoot phenomenon" of traditional reciprocating motion, and eliminating the vibration, wear, and control deviation problems caused by overshoot in principle.

[0040] It is understandable that the second link 13 serves as an intermediate transmission component between the first link 12 and the fourth link 15, forming a three-stage transmission link consisting of the first link 12, the second link 13, the fourth link 15, and the baffle plate 2. Specifically, when the first link 12 rotates around a fixed axis, it drives the second link 13 to move through a hinge point. The other end of the second link 13 is hinged to the fourth link 15, transmitting its own motion to the fourth link 15, which ultimately drives the baffle plate 2 to swing. By adding the second link 13, compared to the motion transmission path where the first link 12 directly drives the fourth link 15, a six-bar linkage 1 with a composite structure, similar to a "double rocker mechanism," is formed. If the first link 12 directly drives the fourth link 15, the swing angle of the baffle plate 2 is limited by the geometric relationship between the crank radius and the length of the fourth link 15.

[0041] It should be noted that the length and hinge position of the second link 13 can be used as design variables, and combined with the parameters of the first link 12 and the fourth link 15, to form different transmission ratios, that is, the ratio of the rotation angle of the first link 12 to the swing angle of the baffle plate 2. For example, if the baffle plate 2 needs to respond quickly to high-frequency waves, it can be designed as an "acceleration transmission", that is, the small-angle rotation of the first link 12 drives the baffle plate 2 to swing at a large angle; if it is necessary to precisely control the small angle of the baffle plate 2, it can be designed as a "deceleration transmission", that is, the large-angle rotation of the first link 12 corresponds to the small-angle swing of the baffle plate 2.

[0042] Generally, when the fourth link 15 is driven solely by the second link 13, the fourth link 15 has a high degree of freedom of motion and is prone to lateral swaying under high-speed swinging or wave impact, leading to loss of attitude control of the flow deflector plate 2. Therefore, the third link 14 is hinged to the frame 11 to form a fixed fulcrum, constituting a rigid triangular structure with the second link 13 and the fourth link 15. This restricts the lateral displacement of the fourth link 15, strictly constraining the swing trajectory of the flow deflector plate 2 within the design plane. For example, when waves impact the flow deflector plate 2 and generate lateral force, the third link 14 can transmit the reaction force through the frame 11 to offset the impact load and prevent the fourth link 15 from shifting due to unilateral force.

[0043] When the fifth link 16 swings down to its lowest point, the third link 14 and the fourth link 15 are collinear, as are the first link 12 and the second link 13, so that the six-bar linkage 1 forms a dead point. Therefore, when the third link 14 and the fourth link 15 are collinear, the torque generated by the wave impacting the flow-damping plate 2 is directly transmitted to the frame 11 through the rigid linear structure formed by the fourth link 15 and the third link 14, avoiding the bending moment borne by the second link 13 and the first link 12, thus ensuring the transmission accuracy of the second link 13 and the first link 12.

[0044] To improve the accuracy of the adjustment of the flow-blocking plate 2, the wave-suppressing device also includes a control component 4 and an angle sensor 5. The angle sensor 5 and the rotary drive component 3 are both electrically connected to the control component 4. The angle sensor 5 is configured to detect the rotation angle of the first connecting rod 12 and feed the detection result back to the control component 4. The control component 4 controls the rotary drive component 3 to work according to the feedback signal of the angle sensor 5, so as to regulate the rotation angle of the flow-blocking plate 2.

[0045] With this setup, the angle sensor 5 continuously monitors the actual rotation angle of the first link 12 and transmits the data to the control unit 4 in real time. The control unit 4 uses a preset algorithm (such as PID control) to compare the deviation between the target angle and the actual angle, dynamically adjusting the rotational speed of the rotary drive 3 to eliminate overshoot or lag caused by mechanical inertia. It should be noted that the specific models of the control unit 4 and the angle sensor 5 can be selected according to the actual application scenario; this embodiment does not impose specific requirements or limitations on this. In addition, the working principles of the control unit 4 and the angle sensor 5 are existing technologies and will not be described in detail.

[0046] To further improve the accuracy of the adjustment of the flow deflector plate 2, the wave suppressor also includes a position sensor. The position sensor is configured to detect the position of the hull 10 during navigation and feed the detection results back to the control unit 4. The control unit 4 controls the rotation drive unit 3 to work according to the feedback signal of the position sensor, so as to adjust the position of the hull 10 during navigation by adjusting the rotation angle of the flow deflector plate 2.

[0047] Understandably, by continuously collecting pitch and roll angle data and combining it with the ship dynamics model, the position sensor can dynamically adjust the water depth and angle of the two side baffle plates 2, specifically in the following two control methods.

[0048] Roll control: When a roll of the hull 10 to one side is detected, the control unit 4 increases the extension of the baffle plate 2 on that side while decreasing the extension on the other side. This generates a counter-righting torque through the difference in lift between the two sides, quickly suppressing the roll amplitude. For example, when the hull 10 lists to the right, the baffle plate 2 on the right side enters the water more deeply, generating a greater upward lift. Combined with the smaller lift on the left side, this creates a righting torque to the left.

[0049] Pitch control: When the bow rises (positive pitch) is detected, the control unit 4 synchronously increases the extension of the two side baffles 2, thereby increasing the total lift to raise the stern and reduce the pitch angle; conversely, when the bow sinks, the extension is reduced.

[0050] It should be noted that the specific model of the pose sensor can be selected according to the actual application scenario. This embodiment does not make specific requirements or restrictions on this. For example, the pose sensor adopts an inertial navigation system.

[0051] Specifically, the fifth link 16 and the baffle plate 2 are set at an angle, so that the baffle plate 2 extends downward on the side away from the fifth link 16. This arrangement, with the angle between the fifth link 16 and the baffle plate 2, allows the tilt angle of the baffle plate 2 to guide the water flow at the stern of the hull 10 to generate an upward lift component or a rearward drag component. Compared to a traditional planar baffle plate 2, this angled structure can more precisely control the angle of attack when the water flow impacts the baffle plate 2. During high-speed navigation, by changing the water entry depth and water flow contact area, it dynamically adjusts the stern water pressure distribution, effectively suppressing pitch (e.g., reducing bow lift) or roll (e.g., balancing the heel of the hull 10).

[0052] In this embodiment, the rotary drive 3 is a servo motor. The rotation speed and direction can be adjusted in real time through the servo control system, achieving precise control of the rotation angle and speed of the flow-blocking plate 2. For example, when wind and waves change, the servo motor can quickly respond to control signals, dynamically adjust the attitude of the flow-blocking plate 2, and promptly change the water pressure distribution at the stern or bottom of the hull 10, more effectively suppressing pitching and rolling, and improving the stability and safety of the ship's navigation.

[0053] This embodiment also provides a boat, which includes a hull 10 and the aforementioned wave-damping device, the wave-damping device being disposed at the stern of the hull 10. It is understood that boats including the aforementioned wave-damping device significantly reduce maintenance frequency and improve operational stability and lifespan.

[0054] Specifically, two wave-damping devices are provided, distributed on both sides of the hull 10 in the forward direction. It should be noted that the specific placement of the wave-damping devices on both sides can be determined according to the shape of the stern bottom, ensuring that the bottom of the wave-damping devices is flush with the stern bottom so that they can effectively block water flow from the hull bottom when the flow-blocking plates 2 are extended. Figure 5 As shown, the bottom of the stern is V-shaped, so the devices on both sides are distributed at an angle. In different ship types, the bottom of the stern may also be horizontal or other irregular structures, and the layout of the wave-suppressing devices will be adjusted accordingly. With this setting, by controlling the extension stroke of the baffle plates 2 of the wave-suppressing devices on the left and right sides, different pressure distributions are formed on both sides of the bottom of the ship, resulting in greater lift on one side and less lift on the other side. The resulting difference can be used to suppress the roll or pitch of the hull 10.

It is neither necessary nor possible to exhaustively describe all embodiments here.
