Description

Technical Field

[0001] The present invention relates to the technical field of marine equipment, and specifically provides a marine vertical motion spoiler. Background Art

[0002] A marine spoiler is a device used to improve the hydrodynamic performance of a ship. It mainly plays a role by changing the water flow state of the ship. When a ship is traveling at high speed on the sea, it faces an extremely complex driving environment. When the ship is traveling, it is affected by factors such as the depth of the water flow, wind speed, and water flow velocity, and will experience rolling and heeling phenomena, that is, the ship will rock from side to side. This has a significant impact on ships, especially large-tonnage ships. It not only easily causes damage to the ship, but there is even a risk of the ship capsizing. For example, for a high-speed car, in order to reduce the lift generated by the air on the vehicle body, a rear wing is often added to the rear of the car to increase the handling and safety of the car during driving. However, a high-speed ship is different from a high-speed car. It not only faces the influence of wind speed, but also faces factors such as water flow. There are many types of marine spoilers. Common ones include vertical motion spoilers. Its structure is simple and it is installed under the stern seal plate of the ship, but its effect is very obvious. It mainly drives the spoiler to move up and down through a cylinder or an electric telescopic rod, so that the movable plate continuously makes vertical up and down movements in the water flow, so as to suppress the formation of stern vortices and turbulence, and optimize the boundary layer flow. Just as described in the patent No. 201910666149.6 for the prior art: Compared with the traditional vertical telescopic spoiler...

[0003] Although the technology disclosed in the patent No. 201910666149.6 overcomes the deficiencies of the traditional vertical motion spoiler, for both of these technologies, a power device is required to continuously drive the spoiler to move in the water flow. Although the formation of vortices and turbulence is reduced, and the occurrence of rolling and heeling phenomena of the ship is reduced, due to the spoiler constantly rising out of the water and entering the water, it also brings a certain resistance to the ship's travel and has a certain impact on the ship's travel.

A set of fixing columns are provided on the first vertical plate. A second vertical plate is provided on the fixing columns. A flow deflecting plate is movably arranged between the first vertical plate and the second vertical plate. The flow deflecting plate is of the same length as the second vertical plate. The second vertical plate and the bottom of the base are on the same horizontal plane. A sliding hole is provided on the first vertical plate. A connecting plate is provided in the sliding hole. One end of the connecting plate is connected to the flow deflecting plate and the other end is provided with a rack, and the rack is engaged with the gear.

[0009] Furthermore, the weight mechanism includes a weight ball arranged on the sliding plate. A set of elastic members are provided at the center of the weight ball. A sliding member is provided on the weight ball above the elastic members.

[0010] Furthermore, the elastic member includes a limiting rod arranged at the center of the weight ball. A spring is provided on the limiting rod.

[0014] The present invention has the following advantages: when the ship is traveling smoothly in water, the counterweight mechanism remains in the neutral position. When the ship is traveling in water and tilting to the left, the entire spoiler tilts to the left with the hull, the left spoiler device tilts to the left, the counterweight mechanism drives the rotating mechanism to rotate, the rotating mechanism drives the lifting mechanism to lift, the lifting mechanism drives the spoiler to lift, and the spoiler lifts and descends in water to achieve spoiler effect and make the hull stable. Similarly, when the ship tilts to the right, the spoiler of the right spoiler device lifts and descends in water to achieve spoiler effect. When the hull of the present invention is traveling smoothly, the spoiler does not lift or descend, and only when the hull tilts will the spoiler perform a vertical spoiler movement, which greatly reduces the resistance brought by the vertical movement of the spoiler during smooth travel of the hull. Moreover, according to the amplitude of the hull tilt, the lifting distance of the lifting mechanism driven by the counterweight mechanism also changes accordingly, reducing the resistance of the hull during tilting and when the spoiler is performing spoiler action.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figure 1 , the present invention provides a marine vertical motion spoiler, including a base 1. A groove 2 is provided inside the base 1. A set of left and right spoiler devices arranged in opposite directions are provided in the groove 2. When the hull is tilted to the left, the left spoiler device deflects the water flow on the left side, and when the hull is tilted to the right, the right spoiler device deflects the water flow on the right side. The left and right spoiler devices have the same structure. Therefore, the following description will mainly focus on the left spoiler device, and the principle of the right spoiler device is the same. The left spoiler device includes a rotating mechanism and a lifting mechanism. The rotating mechanism is fixed inside the groove 2, and the lifting mechanism is fixed on one side of the base 1. The lifting mechanism is engaged with the rotating mechanism. A spoiler plate 3 is provided on the lifting mechanism. When the rotating mechanism rotates, it drives the lifting mechanism to move up and down, and the lifting mechanism drives the spoiler plate 3 to move up and down, that is, the spoiler plate 3 makes a vertical motion. A set of cross beams 4 are provided in the groove 2. A sliding groove 5 is provided on the cross beam 4. A sliding plate 6 is provided at the center of the sliding groove 5. The sliding plate 6 is located at the center of the groove 2 when the hull is running smoothly. When the hull is tilted, it moves left or right in the sliding groove 5. A weight mechanism is provided on the sliding plate 6. The weight mechanism moves its position as the center of gravity changes. The two ends of the weight mechanism are respectively slidably connected to the left and right spoiler devices. The left or right movement of the weight mechanism drives the left or right spoiler device to move.

[0022] Please refer to Figure 2 , the rotating mechanism includes a first gantry 7. The first gantry 7 is arranged on the inner wall of the groove 2 and fixed to the inner wall of the groove 2. A first bearing 8 is embedded in the first gantry 7. A rotating shaft 9 is provided on the first bearing 8. The rotating shaft 9 rotates on the first bearing 8. One end of the rotating shaft 9 is located on the left side of the first gantry 7, and the other end is located on the right side of the first gantry 7. A spiral slider 10 is provided at the bottom of the part of the rotating shaft 9 located on the right side of the first gantry 7. When the spiral slider 10 rotates, it drives the rotating shaft 9 to rotate. A gear 11 is provided at the left end of the rotating shaft 9. The rotating shaft 9 drives the gear 11 to rotate. The gear 11 is engaged with the lifting mechanism, and the gear 11 drives the lifting mechanism to move up and down. A second gantry 12 is provided on the inner wall of the groove 2. A second bearing 13 is embedded in the second gantry 12. The rotating shaft 9 is connected to the second bearing 13. Similarly, the rotating shaft 9 rotates on the second bearing 13. The setting of the second gantry 12 is used to strengthen the strength and stability of the rotating shaft 9 and better adapt to the change of the water flow velocity at sea.

[0023] Please refer to Figure 3, the lifting mechanism includes a limiting member disposed on the base 1. The limiting member includes a first vertical plate 14 disposed on the base 1. A set of fixing posts 15 are provided on the first vertical plate 14. A second vertical plate 16 is provided on the fixing posts 15. The first vertical plate 14 is fixed to the base 1. A spoiler 3 is movably disposed between the first vertical plate 14 and the second vertical plate 16, so that the spoiler 3 is limited in the front-rear direction by the first vertical plate 14 and the second vertical plate 16. The spoiler 3 is of the same length as the second vertical plate 16. The second vertical plate 16 and the bottom of the base 1 are both at the same horizontal plane. When the ship is traveling smoothly, the base 1 just contacts the horizontal plane. Therefore, the second vertical plate 16 and the spoiler 3 are also just in contact with the horizontal plane at this time, but do not extend into the water, so as to avoid forming resistance to the hull when the hull is traveling smoothly in the water. A sliding hole 17 is provided on the first vertical plate 14. A connecting plate 18 is disposed in the sliding hole 17. The sliding hole 17 limits the left-right position of the connecting plate 18. One end of the connecting plate 18 is connected to the spoiler 3, and the other end is provided with a rack 19. The rack 19 meshes with the gear 11. The forward and reverse rotation of the gear 11 drives the lifting of the rack 19. The rack 19 drives the connecting plate 18, and the connecting plate 18 drives the spoiler 3 to lift, that is, to perform a vertical movement.

[0024] Please refer to Figure 4 , the counterweight mechanism includes a counterweight ball 20 disposed on the sliding plate 6. A set of elastic members are provided at the center of the counterweight ball 20. A sliding member is provided on the counterweight ball 20 above the elastic member. The elastic member includes a limiting rod 21 disposed at the center of the counterweight ball 20. A spring 22 is provided on the limiting rod 21. When the counterweight ball 20 moves, it drives the spring 22 to compress or stretch. A limiting block 23 is also provided on the limiting rod 21. A limiting hole 24 is provided on the limiting block 23. The limiting rod 21 movably passes through the limiting hole 24. The limiting block 23 is fixed to the inner wall of the first gantry 7. One end of the spring 22 is fixed to the limiting block 23 and the other end is fixed to the counterweight ball 20. When the counterweight ball 20 moves, it drives the limiting rod 21 to move. The limiting rod 21 passes through the limiting hole 24. A through hole 25 is provided between the first gantry 7 and the limiting block 23.

[0025] It is worth noting that the settings of the counterweight ball 20 and the spring 22 ensure that when the hull is sailing smoothly, the counterweight ball 20 is elastically restricted by the two-side springs 22, and it is not easy for the counterweight ball 20 to shift left and right, which may affect the smooth sailing of the hull. Second, when the hull is tilted, the hull does not remain in a tilted position. Affected by many factors such as wind force and water force, it makes a certain range of left and right tilting movements in the general direction of tilting. The spring 22 continuously compresses or stretches to adapt to a certain range of changes in the hull, causing the rotating shaft 9 to rotate forward and backward repeatedly, and then driving the spoiler 3 to lift and lower repeatedly, forming a spoiler to the water body, making the hull gradually tend to be stable. Third, due to the certain weight of the spoiler 3, when the hull is sailing smoothly, it tends to fall under the influence of its own gravity, which will drive the rack 19 to move downward, and then cause the gear 11 and the rotating shaft 9 to rotate. And the elastic force of the spring 22 in this design is much greater than the gravity of the spoiler 3. When the hull is sailing smoothly, it ensures that the counterweight ball 20 is at the center, and the moving plate 26, the first fixed rod 27 and the second fixed rod 28 will not shift, thus hindering the tendency of the spoiler 3 to fall. The entire counterweight structure is equivalent to a self-locking mechanism for the spoiler 3.

[0026] The sliding member includes a moving plate 26 provided on the counterweight ball 20. When the counterweight ball 20 moves, it drives the moving plate 26 to move. The first fixed rod 27 and the second fixed rod 28 are arranged side by side on the moving plate 26. The moving plate 26 drives the first fixed plate 27 and the second fixed rod 28 to move. The spiral slider 10 is slidably arranged between the first fixed rod 17 and the second fixed rod 28. When the first fixed rod 27 and the second fixed rod 28 move, they always clamp the spiral slider 10 in the middle. The spiral slider 10 rotates along its own shape trajectory to adapt to the movement of the first fixed rod 27 and the second fixed rod 28, and drives the rotating shaft 9 to rotate. One end of the moving plate 26 passes through the through hole 25. The counterweight ball 20 is made of solid metal material to ensure a certain weight of the counterweight ball 20. The base 1 is provided with a transverse stern seal plate 29 and a longitudinal stern seal plate 30. The entire spoiler is fixed on the hull by fixing to the stern seal plate of the hull through the transverse stern seal plate 29 and the longitudinal stern seal plate 30.

[0027] Working principle of the present invention: When the ship is sailing smoothly, it is restricted by the elastic force of a set of left and right springs 22. The counterweight ball 20 is at the center position in the groove 2. When the hull tilts to the left, the entire spoiler also tilts to the left. The counterweight ball 20 tilts to the left, driving the slide plate 6 to move left and downward in the chute 5. The counterweight ball 20 drives the limit rod 21 to move left and downward. The left spring 21 is compressed between the limit block 23 and the counterweight ball 20. The counterweight ball 20 also drives the moving plate 26, the first fixing rod 27 and the second fixing rod 28 on the moving plate 26 to move left and downward. When the first fixing rod 27 and the second fixing rod 28 move, they always sandwich the spiral slider 10 in the middle. The spiral slider 10 rotates along its own shape trajectory to adapt to the movement of the first fixing rod 27 and the second fixing rod 28, and drives the rotating shaft 9 to rotate on the first bearing 8 and the second bearing 13. The rotating shaft 9 drives the gear 11 to rotate. The gear 11 drives the rack 19 to descend. The rack 19 drives the connecting plate 18 to slide downward in the sliding hole 17. The connecting plate 18 drives the spoiler 3 to descend between the first vertical plate 14 and the second vertical plate 16, so that the spoiler 3 moves vertically into the water. Since the hull has small left and right shakes in the general direction of tilting to the left, when the counterweight ball 20 also moves left and right with the left and right shakes, it drives the rotating shaft 9 to rotate forward and backward continuously, and then realizes the vertical reciprocating movement of the spoiler 3 in the water to disturb the water body at the stern of the ship, making the ship gradually tend to sail smoothly. Moreover, the greater the leftward tilt amplitude of the hull, the greater the left and downward movement distance of the counterweight ball 20, the more turns the rotating shaft 9 rotates, and the greater the depth of the spoiler 3 inserted into the water each time during the vertical movement, and the more obvious the spoiler effect. On the contrary, the smaller the leftward tilt amplitude of the hull, the smaller the depth of the spoiler 3 inserted into the water. On the premise of realizing the spoiler effect on the water flow, the resistance to the water body is reduced as much as possible during the spoiler. When the hull tilts to the right, the principle is the same.

[0028] The present invention is simple to operate and convenient to use, and is suitable for comprehensive promotion and application. Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
