DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0029] Please refer to Figures 1-4 , Figure 6 and Figure 8As shown, the present application is a kind of variable balance wing structure for yacht, including hull 1 and side plate 2, side plate 2 is fixedly installed on the upper end of hull 1, side plate 2 both sides are provided with accommodating groove 21, accommodating groove 21 is rotatably installed with balance wing plate 3, the inside of side plate 2 is provided with mounting groove 22, mounting groove 22 is provided with opening and closing drive assembly 4 for controlling balance wing plate 3 unfolding or folding, the inside of hull 1 is provided with installation shell 5, installation shell 5 is fixedly connected to the bottom of side plate 2, the inside of installation shell 5 is symmetrically provided with L-shaped piston pipe 6 at both ends, the bottom of balance wing plate 3 is fixedly provided with buoyancy air bag 31, buoyancy air bag 31 is communicated with the top end of corresponding L-shaped piston pipe 6 through air hose 32, the outside of vertical section of L-shaped piston pipe 6 is extendedly provided with extension housing 61, drive fan wheel 611 is rotatably installed in extension housing 61, piston rod 62 is slidably arranged in the inside of horizontal section of L-shaped piston pipe 6, the inside of installation shell 5 is centrally suspendedly provided with inclined damping block 7, the end of piston rod 62 is always abutted on the inclined wall of inclined damping block 7.

[0030] Specifically, by setting balance wing plate 3, during sailing, balance wing plate 3 is folded and folded in accommodating groove 21, so that hull 1 can maintain smoothness and reduce resistance during sailing, when the yacht is parked on the water surface, the opening and closing drive assembly 4 is used to control the balance wing plate 3 on both sides to gradually unfold, so that a stable triangular support structure is formed between the balance wing plate 3 and the stern, and the buoyancy of buoyancy air bag 31 can effectively reduce the left and right shaking of hull 1, so that the side plate 2 remains balanced and stable, and people can easily carry out leisure activities when the yacht is parked.

[0031] More specifically, as shown, Figure 9 By setting L-shaped piston pipe 6 and inclined damping block 7, when the yacht is parked, the suspended inclined damping block 7 will slightly swing in the opposite direction of the ship's swing under the action of mass inertia, which can effectively offset the vibration energy, thereby reducing the shaking amplitude of hull 1, and in the process of swinging of the piston rod 62 on both sides relative to the inclined damping block 7, the end of the piston rod 62 will move against the inclined wall of the inclined damping block 7, so that the inclined end of the piston rod 62 will be pushed inward, and the raised end of the piston rod 62 will be pulled outward, between pushing and pulling, the air pressure in the buoyancy air bag 31 at the inclined end increases to make the volume expand, and its buoyancy increases, the air pressure in the buoyancy air bag 31 at the raised end decreases to make the volume shrink, and its buoyancy decreases, thereby generating a buoyancy difference between the two ends of the buoyancy air bag 31, so that the hull 1 is more easily overcome by the tilting effect, which is conducive to inhibiting the tilting tendency of the hull 1.

[0032] As shown, Figure 5 The inclined damping block 7 is fixedly arranged in the fixed frame 71, the fixed frame 71 is fixedly connected with the lifting rope 72 at both sides, and the top end of the lifting rope 72 is connected with the bottom of the side plate 2.

[0033] Specifically, the inclined damping block 7 is installed in a suspended manner through the hanging rope 72. When the hull 1 swings, the inclined damping block 7 will swing in the opposite direction under the action of mass inertia, so as to slow down the vibration amplitude. In actual application, a hydraulic damper can be additionally arranged at the bottom of the fixed frame 71, so that the mechanical energy generated by the swing can be converted into heat energy or other forms of energy by the damper to dissipate it.

[0034] As shown in Figure 6 and Figure 8 , one end of the piston rod 62 extends into the horizontal section of the L-shaped piston pipe 6 and is fixedly connected with a piston. The piston is adapted to be slidingly installed in the horizontal section of the L-shaped piston pipe 6. The other end of the piston rod 62 is fixedly connected with a rotating frame 621. The rotating frame 621 is rotatably installed with a synchronous roller 622. A baffle 623 is arranged on the outer wall of the piston rod 62. A compression spring 624 is arranged between the baffle 623 and the end of the L-shaped piston pipe 6. The synchronous roller 622 is always abutted against the side wall of the inclined damping block 7 under the pushing force of the compression spring 624.

[0035] Specifically, the compression spring 624 is always in a compressed state, so that the synchronous roller 622 is always abutted against the side wall of the inclined damping block 7 under the pushing force of the compression spring 624. When the piston rod 62 swings relative to the inclined damping block 7, the synchronous roller 622 will roll along the side wall of the inclined damping block 7, so that the piston rod 62 can perform a corresponding linear pulling movement in the L-shaped piston pipe 6, thereby changing the air pressure in the two-end floating air bag and the generated buoyancy.

[0036] As shown in Figures 6-9 , the extension housing 61 is internally provided with a driving fan wheel 611. The driving fan wheel 611 is fixedly sleeved on a driving shaft 612. The driving shaft 612 is in rotational sealing fit with the extension housing 61. The driving shaft 612 is fixedly provided with a winding disc 613 at both ends. The winding disc 613 is wound with a pull rope 614. One end of the pull rope 614 is connected with the counterweight 8.

[0037] Further, the mounting shell 5 is fixedly provided with a fixed seat 51 on the inner walls of both sides. The L-shaped piston pipe 6 is fixedly installed in the fixed seat 51. The mounting shell 5 is internally provided with a guide wheel 52 fixedly arranged at the bottom. The pull rope 614 passes through the guide wheel 52 and is connected with the counterweight 8. The mounting shell 5 is internally horizontally fixedly provided with a sliding rod 53. The counterweight 8 is linearly slidingly installed on the sliding rod 53.

[0038] Specifically, by setting the drive fan wheel 611, when the hull 1 is tilted to the right, the right end of the piston rod 62 will push inward, at this time the airflow in the right end of the L-shaped piston pipe 6 will flow upwards, driving the drive fan wheel 611 to rotate clockwise, the right end of the winding reel 613 starts to unwind, at the same time the left end of the piston rod 62 will pull outward, the airflow in the left end of the L-shaped piston pipe 6 will flow downwards, driving the drive fan wheel 611 to rotate clockwise synchronously, at this time the left end of the winding reel 613 starts to wind, so that the pull rope 614 pulls the counterweight 8 to slide along the slide rod 53 left and right between winding and unwinding, and the same applies when the hull 1 is tilted to the left, the left end of the winding reel 613 starts to unwind, while the right end of the winding reel 613 starts to wind, the pull rope 614 will pull the counterweight 8 to slide along the slide rod 53 to the right, so that the airflow generated by the piston push-pull process, combined with the winding reel 613 and the pull rope 614, can pull the counterweight 8 to slide in the opposite direction of the tilt direction all the time, to balance the center of gravity of the two ends of the hull 1, further slowing down the swing trend, which is conducive to keeping the hull 1 balanced and stable.

[0039] As shown in Figure 7 and Figure 9 , the drive shaft 612 at both ends is rotatably connected to the extension shell 61 through a torsion spring (not shown in the figure), and the pull rope 614 is always kept taut under the action of torsion, and the taut pull rope 614 exerts a pulling force on the counterweight 8 in a force direction that is always parallel to the slide rod 53 after passing through the guide wheel 52.

[0040] Specifically, in the initial state, the hull 1 remains balanced, and the drive shaft 612 at both ends maintains the tension of the pull rope 614 under the action of torsion, at this time the counterweight 8 is located at the central position, when the hull 1 swings, the drive shaft 612 at one end starts to rotate so that the winding reel 613 starts to wind, while the drive shaft 612 at the other end also rotates in the same direction so that the winding reel 613 on it starts to unwind, in this process the pull rope 614 remains taut and parallel to the slide rod 53, thereby ensuring the correct force direction on the counterweight 8 and avoiding the influence of the vertical component force on the sliding process of the counterweight 8.

[0041] As shown in Figure 3 and Figure 5 , the opening and closing drive assembly 4 includes a telescopic cylinder 41, which is fixedly arranged in the mounting groove 22, and the output end of the telescopic cylinder 41 is fixedly connected with a connecting plate 42, both ends of the connecting plate 42 are fixedly provided with tooth groove plates 43, the tooth groove plates 43 are slidably installed in the mounting groove 22, a guide rod 23 is fixedly arranged in the mounting groove 22, the guide rod 23 slidably penetrates through the connecting plate 42, and the edge of the end of the balance wing plate 3 is provided with a transmission tooth 33 which is engaged with the tooth groove plate 43.

[0042] Specifically, the telescopic air cylinder 41 is started to push the tooth groove plates 43 at both ends forward, at this time the tooth groove plates 43 will drive the balance wing plates 3 to rotate inward and fold until completely hidden in the accommodating grooves 21, when it is needed to unfold the balance wing plates 3, the telescopic air cylinder 41 pulls the tooth groove plates 43 at both ends backward, at this time the tooth groove plates 43 will drive the balance wing plates 3 to rotate outward until completely unfolded, thereby realizing the opening and closing process of the balance wing plates 3, the control is flexible and simple, and the transmission is reliable and stable.

[0043] In the embodiment, the maximum unfolding angle of the balance wing plates 3 is 90°, and the unfolded balance wing plates 3 are perpendicular to the length direction of the hull 1.

[0044] The working principle of the application is as follows: Figures 1-9As shown, in use, during sailing, the balance wings 3 are folded and stored in the accommodating grooves 21, so that the hull 1 can maintain smoothness and reduce resistance during sailing. When the yacht is parked on the water surface, the balance wings 3 on both sides are gradually unfolded by the opening and closing driving assembly 4, so that a stable triangular support structure is formed between the balance wings 3 and the stern, and the left and right shaking of the hull 1 is effectively reduced by the buoyancy of the buoyancy air bags 31, so that the hull 2 maintains balance and stability. When the yacht shakes left and right due to waves on the water surface when parked, the suspended inclined damping blocks 7 will slightly swing in the opposite direction of the ship's swing under the action of mass inertia, which can effectively offset the vibration energy and slow down the shaking amplitude of the hull 1. Meanwhile, during the swinging process of the piston rods 62 on both sides relative to the inclined damping blocks 7, the end of the piston rod 62 will move against the inclined wall of the inclined damping block 7, so that the inclined end of the piston rod 62 will be pushed inward, and the raised end of the piston rod 62 will be pulled outward. Between the pushing and pulling, the air pressure in the inclined end of the buoyancy air bag 31 increases to make the volume expand, and the buoyancy increases, and the air pressure in the raised end of the buoyancy air bag 31 decreases to make the volume shrink, and the buoyancy decreases, so that the buoyancy difference between the two ends of the buoyancy air bag 31 is generated, so that the hull 1 is more easily overcome by the shaking and tilting effect, which is conducive to suppressing the tilting trend of the hull 1. When the hull 1 tilts to the right, the right end of the piston rod 62 will be pushed inward, at this time the airflow in the right end of the L-shaped piston pipe 6 will flow upward, driving the driving fan wheel 611 to rotate clockwise, and the right end of the winding reel 613 starts to unwind, while the left end of the piston rod 62 will be pulled outward, and the airflow in the left end of the L-shaped piston pipe 6 will flow downward, driving the driving fan wheel 611 to rotate clockwise synchronously, at this time the left end of the winding reel 613 starts to wind, so that the pulling rope 614 pulls the counterweight 8 to slide to the left along the slide rod 53 between winding and unwinding. Similarly, when the hull 1 tilts to the left, the left end of the winding reel 613 starts to unwind, and the right end of the winding reel 613 starts to wind, and the pulling rope 614 pulls the counterweight 8 to slide to the right along the slide rod 53. By using the airflow generated by the piston pushing and pulling process, combined with the winding reel 613 and the pulling rope 614, the counterweight 8 can always slide in the opposite direction of the tilting direction, so as to balance the center of gravity of the hull 1 at both ends, and further slow down the swinging trend.

[0045] The above describes one embodiment of the present application in detail, but the above description is only a preferred embodiment of the present application, and cannot be considered as limiting the scope of the present application. Any equivalent changes and improvements made within the scope of the present application should still belong to the patent scope of the present application.
