Description

Technical Field

[0001] This invention relates to the field of marine equipment technology, specifically to a marine vertical motion spoiler. Background Technology

[0002] Marine spoilers are devices used to improve the hydrodynamic performance of ships. They primarily function by altering the ship's current state. Ships traveling at high speeds at sea face extremely complex navigational environments. Affected by water depth, wind speed, and current velocity, ships may experience rolling and heeling, meaning they will sway from side to side. This has a significant impact on ships, especially large vessels, easily causing damage and even posing a risk of capsizing. For example, to reduce the lift generated by airflow on a high-speed car, a tail fin is often added to improve handling and safety. Ships differ from high-speed cars in that they are affected not only by wind speed but also by water currents. There are many types of marine spoilers, the most common being the vertically moving spoiler. Its structure is simple, installed below the stern plate, yet its effect is significant. It primarily uses a cylinder or electric telescopic rod to move the spoiler up and down, causing the movable plate to continuously move vertically in the water flow. This suppresses the formation of stern eddies and turbulence, optimizing boundary layer flow. As described in patent number 201910666149.6, compared to traditional vertically telescopic spoilers...

[0003] Although the technology disclosed in patent number 201910666149.6 overcomes the shortcomings of traditional vertical motion spoilers, both technologies require a power device to continuously drive the spoiler to move in the water flow. Although this reduces the formation of eddies and turbulence and reduces the occurrence of ship roll and heel, the continuous rising and falling of the spoiler also brings certain resistance to the ship's movement, thus affecting the ship's navigation. Summary of the Invention

[0004] To address the technical problems mentioned in the background section, the present invention provides a marine vertical motion spoiler, employing the following technical solution:

[0005] The device includes a base with a groove on its inner side. Inside the groove are a set of left-hand and right-hand spoilers arranged in opposite directions. The left-hand and right-hand spoilers have the same structure. The left-hand spoiler includes a rotating mechanism and a lifting mechanism. The rotating mechanism is fixed inside the groove, and the lifting mechanism is fixed to one side of the base. The lifting mechanism meshes with the rotating mechanism. A spoiler is installed on the lifting mechanism, which drives the spoiler to rise and fall. A set of crossbeams is installed inside the groove. A slide is installed on the crossbeams, and a slide plate is installed at the center of the slide plate. A counterweight mechanism is installed on the slide plate, and the two ends of the counterweight mechanism are slidably connected to the left-hand and right-hand spoilers, respectively.

[0006] Furthermore, the rotating mechanism includes a first gantry frame, which is disposed on the inner wall of the groove. A first bearing is embedded in the first gantry frame, and a rotating shaft is disposed on the first bearing. One end of the rotating shaft is located on the left side of the first gantry frame, and the other end is located on the right side of the first gantry frame. A spiral slider is disposed at the bottom of the part of the rotating shaft located on the right side of the first gantry frame, and a gear is disposed at the left end of the rotating shaft. The gear meshes with the lifting mechanism.

[0007] Furthermore, a second gantry frame is provided on the inner wall of the groove, and a second bearing is embedded in the second gantry frame, with the rotating shaft connected to the second bearing.

[0008] Furthermore, the lifting mechanism includes a limiting member mounted on the base. The limiting member includes a first vertical plate mounted on the base. A set of fixed columns are mounted on the first vertical plate, and a second vertical plate is mounted on the fixed columns. A spoiler is movably mounted between the first and second vertical plates. The spoiler has 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, and a connecting plate is provided in the sliding hole. One end of the connecting plate is connected to the spoiler, and the other end is provided with a rack, which meshes with a gear.

[0009] Furthermore, the counterweight mechanism includes a counterweight ball mounted on the slide plate, a set of elastic elements at the center of the counterweight ball, and a sliding element mounted on the counterweight ball above the elastic elements.

[0010] Furthermore, the elastic element includes a limiting rod disposed at the center of the counterweight ball, a spring disposed on the limiting rod, a limiting block disposed on the limiting rod, a limiting hole disposed on the limiting block, the limiting rod movably passing through the limiting hole, the limiting block being fixed to the inner wall of the first gantry frame, one end of the spring being fixed to the limiting block and the other end being fixed to the counterweight ball, and a through hole being disposed between the first gantry frame and the limiting block.

[0011] Furthermore, the sliding component includes a movable plate disposed on the counterweight ball, a first fixed rod and a second fixed rod disposed side by side on the movable plate, a spiral slider slidably disposed between the first fixed rod and the second fixed rod, and one end of the movable plate passing through a perforation.

[0012] Furthermore, the counterweight ball is made of solid metal.

[0013] Furthermore, the base is equipped with a transverse stern sealing plate and a longitudinal stern sealing plate.

[0014] This invention has the following advantages: When the boat is sailing smoothly in the water, the counterweight mechanism remains in a neutral position. When the boat rolls to the left, the entire spoiler rolls to the left with the hull, causing the left-hand spoiler to roll to the left as well. The counterweight mechanism drives the rotating mechanism to rotate, which in turn drives the lifting mechanism to rise and fall. The lifting mechanism then drives the spoiler to rise and fall, causing the spoiler to rise and fall in the water, thus creating a turbulent current and stabilizing the boat. Similarly, when the boat rolls to the right, the spoiler of the right-hand spoiler moves up and down in the water to create a turbulent current. In this invention, the spoiler does not rise or fall when the boat is sailing smoothly; it only moves vertically when the boat rolls. This greatly reduces the resistance caused by the vertical movement of the spoiler when the boat is sailing smoothly. Furthermore, the lifting distance driven by the counterweight mechanism changes according to the degree of the boat's roll, reducing the resistance of the boat when it is rolling and the spoiler is creating a turbulent current.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please refer to Figure 1 This invention provides a marine vertical motion spoiler, including a base 1. A groove 2 is formed on the inner side of the base 1. A set of left-hand and right-hand spoilers are arranged in opposite directions within the groove 2. When the ship rolls to the left, the left-hand spoiler disrupts the water flow on the left side; when the ship rolls to the right, the right-hand spoiler disrupts the water flow on the right side. The left-hand and right-hand spoilers have the same structure; therefore, the following description focuses on the left-hand spoiler. The right-hand spoiler operates on the same principle. The left-hand spoiler includes a rotating mechanism and a lifting mechanism. The rotating mechanism is fixed inside the groove 2, and the lifting mechanism is fixed to one side of the base 1. The lifting mechanism engages with the rotating mechanism, and the lifting mechanism... The mechanism is equipped with a spoiler 3. When the rotating mechanism rotates, it drives the lifting mechanism to move, which in turn drives the spoiler 3 to move up and down, i.e., the spoiler 3 moves vertically. A set of crossbeams 4 are set in the groove 2. A slide 5 is set on the crossbeams 4. A slide plate 6 is set at the center of the slide 5. When the hull is running smoothly, the slide plate 6 is located at the center of the groove 2. When the hull tilts, it moves to the left or right in the slide 5. A counterweight mechanism is set on the slide plate 6. The counterweight mechanism moves its position as the center of gravity changes. The two ends of the counterweight mechanism are slidably connected to the left-hand spoiler and the right-hand spoiler, respectively. The left-hand or right-hand movement of the counterweight mechanism drives the left-hand spoiler or the right-hand spoiler to move.

[0022] Please refer to Figure 2 The rotating mechanism includes a first gantry 7, which is fixed to the inner wall of the groove 2. A first bearing 8 is embedded in the first gantry 7, and a rotating shaft 9 is mounted 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 mounted at the bottom of the right side portion of the rotating shaft 9. When the spiral slider 10 rotates, it drives the rotating shaft 9 to rotate. A gear 11 is mounted on the left end of the rotating shaft 9. The rotating shaft 9 drives the gear 11 to rotate. The gear 11 meshes with the lifting mechanism, and the gear 11 drives the lifting mechanism to lift. A second gantry 12 is mounted on the inner wall of the groove 2, and a second bearing 13 is embedded in the second gantry 12. The rotating shaft 9 is connected to the second bearing 13, and the rotating shaft 9 also rotates on the second bearing 13. The second gantry 12 is used to strengthen the strength and stability of the rotating shaft 9, making it more adaptable to changes in the flow velocity of the sea.

[0023] Please refer to Figure 3The lifting mechanism includes a limiting member mounted on the base 1. The limiting member includes a first vertical plate 14 mounted on the base 1, a set of fixing posts 15 mounted on the first vertical plate 14, and a second vertical plate 16 mounted on the fixing posts 15. The first vertical plate 14 is fixed to the base 1. A spoiler 3 is movably mounted between the first vertical plate 14 and the second vertical plate 16, limiting the spoiler 3 in the forward and backward direction. The spoiler 3 and the second vertical plate 16 have the same length. The second vertical plate 16 and the bottom of the base 1 are both on the same horizontal plane. When the boat is sailing smoothly, the base 1 is exactly level with the horizontal plane. Therefore, the second vertical plate 16 and the spoiler 3 are in contact with the horizontal surface at this time, but do not extend into the water, so as to avoid creating resistance to the hull when the hull is sailing smoothly in the water. The first vertical plate 14 is provided with a sliding hole 17, and a connecting plate 18 is provided in the sliding hole 17. The sliding hole 17 limits the left and right positions 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 rack 19 to rise and fall. The rack 19 drives the connecting plate 18, and the connecting plate 18 drives the spoiler 3 to rise and fall, that is, to make vertical movement.

[0024] Please refer to Figure 4 The counterweight mechanism includes a counterweight ball 20 mounted on the slide plate 6. A set of elastic elements is located at the center of the counterweight ball 20. A sliding element is located on the upper side of the elastic elements on the counterweight ball 20. The elastic elements include a limiting rod 21 located at the center of the counterweight ball 20. A spring 22 is mounted on the limiting rod 21. When the counterweight ball 20 moves, it causes the spring 22 to compress or stretch. A limiting block 23 is also mounted on the limiting rod 21. A limiting hole 24 is provided on the limiting block 23. The limiting rod 21 moves through the limiting hole 24. The limiting block 23 is fixed to the inner wall of the first gantry frame 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 causes 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 frame 7 and the limiting block 23.

[0025] It is worth noting that the arrangement of the counterweight ball 20 and spring 22 serves two purposes: First, when the hull is sailing smoothly, the counterweight ball 20 is elastically restricted by the springs 22 on both sides, preventing it from shifting left or right and affecting the smooth sailing of the hull. Second, when the hull is heeling, it does not remain in a single heeling posture. It is affected by wind, water force, and other factors, and undergoes a certain degree of left and right heeling movement in the general direction of heeling. The spring 22 adapts to the changes in the hull's range of motion by continuously compressing or stretching, causing the rotating shaft 9 to continuously rotate in both directions. This, in turn, drives the spoiler 3 to repeatedly rise and fall, thus affecting the water... The spoiler 3 creates a turbulence, gradually stabilizing the ship. Thirdly, because the spoiler 3 has a certain weight, it tends to sag under its own weight when the ship is sailing smoothly. This causes the rack 19 to move downwards, which in turn causes the gear 11 and shaft 9 to rotate. The spring 22 in this design has a much greater elastic force than the weight of the spoiler 3. When the ship is sailing smoothly, the counterweight ball 20 is kept in the center, and the moving plate 26, the first fixed rod 27, and the second fixed rod 28 do not shift. Therefore, the tendency of the spoiler 3 to sag is hindered. The entire counterweight structure is also equivalent to the self-locking mechanism of the spoiler 3.

[0026] The sliding component includes a movable plate 26 mounted on the counterweight ball 20. When the counterweight ball 20 moves, it drives the movable plate 26 to move. A first fixed rod 27 and a second fixed rod 28 are arranged side by side on the movable plate 26. The movable plate 26 drives the first fixed plate 27 and the second fixed rod 28 to move. The spiral slider 10 is slidably mounted 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, the spiral slider 10 is always clamped 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 movable plate 26 passes through the through hole 25. The counterweight ball 20 is made of solid metal to ensure a certain weight. A transverse stern sealing plate 29 and a longitudinal stern sealing plate 30 are provided on the base 1. The transverse stern sealing plate 29 and the longitudinal stern sealing plate 30 are fixed to the stern sealing plate of the hull to realize the entire spoiler is fixed to the hull.

[0027] The working principle of this invention: When the ship is sailing smoothly, it is restricted by the elastic force of a set of springs 22 on the left and right sides. The counterweight ball 20 is located in the center of the groove 2. When the ship tilts to the left, the entire spoiler also tilts to the left. The counterweight ball 20 tilts to the left, and the counterweight ball 20 drives the slide plate 6 to move to the lower left in the slide groove 5. The counterweight ball 20 drives the limiting rod 21 to move to the lower left. The spring 21 on the left side is compressed between the limiting block 23 and the counterweight ball 20. The counterweight ball 20 also drives the moving plate 26 and the first fixed rod 27 and the second fixed rod 28 on the moving plate 26 to move to the lower left. 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 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. 9 drives the connecting plate 18 to slide down within 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, causing the spoiler 3 to move vertically into the water. Since the hull is also slightly swaying left and right in the direction of left-right heeling, when the counterweight ball 20 also moves left and right with the left-right swaying, it drives the rotating shaft 9 to continuously rotate forward and backward, thereby realizing the spoiler 3 to move vertically up and down in the water, disturbing the water at the stern, and making the ship gradually move more steadily. The greater the left-right heeling of the hull, the greater the distance the counterweight ball 20 moves to the left and downward, the more rotations the rotating shaft 9 makes, and the greater the depth of the spoiler 3 when it moves vertically into the water each time, and the more obvious the disturbance effect. Conversely, the smaller the left-right heeling of the hull, the shallower the depth of the spoiler 3 into the water. Under the premise of realizing the disturbance effect on the water flow, the resistance to the water body during the disturbance is minimized as much as possible. When the hull is right-right heeling, the principle is the same.

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