Description

Technical Field

[0001] The invention relates to the technical field of ships, and in particular to a ship tail wing. Background Art

[0002] The marine empennage is an important hydrodynamic structure, which is widely used in various types of ships and vessels to improve navigation performance and handling stability. With the continuous development of shipping and marine engineering technology, the design and application of empennages have gradually become a key research direction in the field of navigation. In the early days of navigation, ships mainly relied on the power of sails and water flow, and the concept of empennages was not obvious. With the introduction of steam engines and internal combustion engines, the power and speed of ships have been greatly improved, and the empennage has begun to receive attention as an auxiliary structure to improve navigation performance. The main function of the empennage is to enhance the maneuverability and stability of the ship by adjusting the flow direction and speed of the water flow. Especially in high-speed navigation and complex waters, the empennage can effectively reduce the swaying and bumping of the ship, and improve the safety and comfort of navigation; There are still the following defects in specific use: 1. Rolling and pitching will affect the ship's controllability, resulting in unstable heading and difficulty in precise control; violent shaking will make passengers feel uncomfortable and even cause seasickness, reducing the riding experience. In addition, shaking may cause cargo to shift, be damaged or capsize, affecting cargo safety and transportation efficiency.

[0003] 2. In addition, the increased resistance makes it impossible for the ship to maintain the designed speed, affecting navigation efficiency and time scheduling. In order to overcome the greater resistance, the engine requires additional power, resulting in a significant increase in fuel consumption and increased operating costs. At the same time, the huge resistance will affect the ship's maneuverability, making it more difficult to maintain a stable course in waves.

This is particularly important for ships that need to overcome greater resistance; by adjusting the expansion degree of the wingspan, the aerodynamic or hydrodynamic performance of the tail wing plate can be optimized, making the ship more efficient during navigation; the tail wing plate is one of the important components for maintaining the stability of the ship's heading. The expansion of the wingspan can increase the lateral stability of the tail wing plate, making it more difficult for the ship to deviate from the heading due to the influence of side wind or water flow during navigation; in sea conditions with strong winds and waves, the ship is prone to swaying. Through the dynamic wingspan expansion mechanism, the damping effect of the tail wing can be increased, the roll and pitch of the ship can be reduced, and the navigation stability can be improved; when the heading needs to be changed, the dynamic wingspan expansion mechanism can quickly adjust the force area and angle of the tail wing plate, thereby generating a greater steering torque, helping the ship to complete the steering action faster, thereby improving maneuverability and increasing steering energy.

[0017] (2) The present invention utilizes the coordination of the guide plate and the arc rod.

[0018] (3) The present invention utilizes the adsorption hood and the outer groove plate to cooperate with each other, and the capture screen wing mechanism can more efficiently capture pollutants generated during the navigation of the ship. Through its staggered movement design, the contact area and contact time with the pollutants are increased, thereby improving the capture efficiency; the result of efficient capture of pollutants directly reduces the amount of pollutants discharged into the ocean by the ship.

Through its unique structure and dynamic adjustment ability, it can disperse and weaken the impact of wind and waves on the ship and improve the navigation stability of the ship.

[0024] The complete working principle and steps of the above embodiment are as follows: Initial qualification: Figure 1 As shown, the tail wing body 13 is an important structure of the stern, which is mainly used to improve the stability and maneuverability of the ship. During navigation, the tail wing body 13 generates lift and resistance through interaction with the water flow, thereby helping the ship to maintain its course and attitude. Especially when sailing at high speed, the tail wing body 13 can effectively prevent the ship from bumping and improve the stability of driving.

[0025] When the ship is sailing, water flows through the tail wing body 13, forming a certain hydrodynamic force. According to the design, the angle and shape of the tail wing body 13 will affect the flow of water, thereby adjusting the lift and stability of the ship. The coordinated use of the rudder makes the control more precise, and the ship can turn and adjust the route more quickly.

[0026] In addition, the tail wing body 13 also plays a key role in reducing the water resistance of the ship, helping the ship to maintain good performance under different sailing conditions. When the ship breaks through the waves, the water flows through the hull at a very high speed, especially when it reaches the stern, the tail wing body 13 becomes the key regulator of this force. The water flow separates on the surface of the tail wing body 13, forming two different flow paths. The upper water flow is guided to flow upward due to the shape of the tail wing body 13, generating downward lift, which helps to improve the stability of the stern. The lower water flow is hindered by the tail wing body 13, forming a backward thrust, which is opposite to the direction of the forward power of the hull, but this resistance also helps the ship to maintain a straight line or achieve a turn.

[0027] Hull 1: As the outermost layer of the hull, the hull 1 not only protects everything inside the ship, but also reduces water resistance and increases the speed through its streamlined design. The smooth transition between the hull 1 and the tail wing body 13 ensures the continuity of the water flow during passage, reduces the generation of turbulence and vortices, and further improves the sailing efficiency; Deck 11: Deck 11 is the platform for crew members to work and live, and is also the main area for cargo loading and unloading. During navigation, the stability and safety of deck 11 are of vital importance. The tail wing 13 indirectly ensures the safety of personnel and cargo on deck 11 by maintaining the stability of the hull; Cabin 12: The cabin 12 is loaded with cargo, fuel, mechanical equipment, etc. Its layout and weight distribution have a direct impact on the stability of the ship. The tail wing body 13 helps the ship maintain balance under different loading conditions and prevents capsizing by adjusting the buoyancy distribution at the stern; Radar tower 14: As the "eyes" of the ship, the radar tower 14 is responsible for detecting the surrounding navigation environment and obstacles to ensure navigation safety. The tail wing body 13 improves the maneuverability of the ship, allowing the captain to more accurately adjust the route according to the radar information and avoid danger.

[0028] When using: The steps of the dynamic wingspan expansion mechanism 2 for improving the ship's ability to resist crosswind by increasing the hydrodynamic area of ​​the tail wing plate 13 are as follows: like Figure 3 to Figure 4 As shown, when encountering complex water flow conditions and strong wind conditions, the operator presses the controller switch electrically connected to the upper end of the electric telescopic rod 24, and then the controller switch is activated to drive the electric telescopic rod 24 to retract backward. Therefore, the backward movement and contraction of the electric telescopic rod 24 will drive the connecting rod 25 fixedly connected to one end of the electric telescopic rod 24 to deflect downward. The downward deflection of the connecting rod 25 will pull the external rod 26, which is rotatably connected to one end of the connecting rod 25, to deflect upward. In this way, the upward deflection of the external rod 26 will cause the rotating shaft 212, which passes through one end of the external rod 26 and is rotatably connected, to rotate. The rotation of the moving shaft 212 will drive the fixed block 211 fixedly connected to one end of the rotating shaft 212 to flip backwards, so the rod block 210 fixedly connected to the upper end of the fixed block 211 will flip backwards together with the backward flipping of the fixed block 211. The backward flipping of the rod block 210 will cause the plate wing 29, which is rotatably connected to one end of the rod block 210, to open to the side close to the tail wing body 13. In this way, when the plate wing 29 opens to one side, the rotating block 28 will be horizontally deflected on the outer wall of one end of the wedge block 27. In summary, the deflection and opening of the plate wing 29 enhance the controllability and stability of the ship. When the plate wing 29 is unfolded, it can change the fluid dynamic characteristics of the tail wing, increase lift, and thus improve the performance of the ship when sailing at high speed or turning; The cambered wing guide mechanism 3 steps of optimizing the hydrodynamic performance of the tail wing body 13 by changing the relative angle and position between the tail wing body 13 and the water flow: like Figure 5As shown in the figure 6, when the rotating shaft 212 rotates, the crank 31 rotatably connected to the outer wall of the rotating shaft 212 will also reciprocate back and forth. The back and forth reciprocating deflection of the crank 31 will cause the sleeve shaft 33 slidably connected to the outer wall of the fixed shaft 32 to reciprocate on the fixed shaft 32. In this way, the reciprocating movement of the sleeve shaft 33 will pull the rotating rod 35 rotatably connected to the outer wall of the connecting shaft 34 to drive the short shaft 36 to rotate. The rotation of the short shaft 36 will cause the longitudinal bevel gear 38 fixedly connected to one end thereof to rotate, and then the transverse bevel gear 311 meshing with the longitudinal bevel gear 38 will rotate synchronously with the rotation of the longitudinal bevel gear 38, and the outer wall of the transverse bevel gear 311 fixedly connected to one side of the transverse bevel gear 311 will rotate synchronously. The circular column 312 of the wall will rotate with the rotation of the transverse bevel gear 311, so that the inclined rod 313 fixedly connected to the outer wall of the bottom end of the circular column 312 will rotate, and the guide plate 315 fixedly connected to the outer wall of the inclined rod 313 will rotate with the rotation of the inclined rod 313. In addition, the arc rod 314 rotatably connected to the outer wall of the bottom end of the inclined rod 313 will also deflect with the rotation of the inclined rod 313. The deflection of the arc rod 314 will cause the block 317 fixedly connected to one end of the inner shaft 316 to slide on the outer wall surface of the fan-shaped plate 318, thereby limiting the rotation offset trajectory of the guide plate 315 to be an arc shape, thereby optimizing the flow of water on the tail wing plate body 13 and reducing resistance; The capture screen wing mechanism is used to capture and collect floating impurities on the water surface. 4 steps: like Figures 7 and 8 As shown, when the connecting rod 25 is deflected, the short rod 41 connected to one end of the connecting rod 25 will also be deflected downward, and then the deflection of the short rod 41 will pull the long rod 42 to deflect downward, and as the long rod 42 deflects downward, the moving block 43 fixedly connected to one end of the long rod 42 will be pulled to slide on the outer groove plate 46, so the vertical block 44 fixedly connected to the outer wall of the moving block 43 will pull the adsorption cover 45 to move horizontally first synchronously, and the outer groove plate 46 is provided with a staggered slide groove, so when one end of the vertical block 44 is slidably connected to the staggered slide groove provided in the outer groove plate 46, the moving trajectory of the vertical block 44 will change, so that the change of the moving trajectory of the vertical block 44 will cause the moving block 43 to drive the moving trajectory of the adsorption cover 45 to change synchronously, so that the circular through holes provided on the surface of the adsorption cover 45 can collect and capture impurities in multiple directions on the surface of the water area along the staggered moving trajectory of the moving block 43; Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
