Description

Technical Field

[0001] This utility model relates to the field of marine equipment technology, specifically to a medium- and high-speed marine movable spoiler. Background Technology

[0002] In the field of ship design and manufacturing, especially in the motion control of medium and high-speed ships, traditional methods of ship attitude adjustment rely heavily on hydraulic control systems. However, these systems have revealed some obvious shortcomings in practical applications.

[0003] First, the control frequency of the hydraulic control system is relatively slow, resulting in an insufficient response to the adjustment of the ship's attitude. This makes it difficult to meet the high requirements of modern medium and high-speed ships for motion attitude control. Especially when facing complex and ever-changing sea conditions, this delay may lead to a decrease in the ship's motion performance and even threaten navigation safety.

[0004] Secondly, hydraulic control systems occupy a large space, which is difficult to implement in ships with compact space layouts, especially in areas such as the stern deck. Due to limited space, it is often difficult to meet the installation requirements of hydraulic control systems, thus limiting the widespread application of these systems on ships.

[0005] In addition, traditional ship attitude adjustment mechanisms often lack specificity in describing the structural form of spoiler mechanisms and lack detailed implementation methods, such as how the spoiler mechanism moves vertically and how it works in coordination with other ship systems.

[0006] Therefore, we have made technical improvements to the existing equipment and developed a new type of movable spoiler for medium and high speed ships to solve the above problems. Utility Model Content

[0007] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a medium- and high-speed marine movable spoiler that can improve the pitch, roll, pitch and heel of a ship and improve the ship's motion attitude.

[0010] The panel is detachably fixed to the back panel, and the center of the panel is open.

[0011] A rotary drive mechanism is located on the inner and outer sides of the stern sealing plate, respectively, and the power output end of the rotary drive mechanism passes through the stern sealing plate and the back plate in sequence. An eccentric disk is fixedly provided on the power output end of the rotary drive mechanism. The eccentric disk is placed between the back plate and the panel. An eccentric shaft is axially fixed on the eccentric disk.

[0012] A movable plate is also provided between the back plate and the front plate. The top of the movable plate has an opening for the eccentric shaft to pass through, so that when the eccentric shaft moves, the movable plate moves vertically to the drive groove outside the back plate and the front plate.

[0013] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the above-mentioned medium and high speed marine movable spoiler has several connecting studs vertically fixed on the side of the back plate facing the panel, and several guide grooves for the connecting studs to extend vertically on the movable plate. The panel, back plate and stern plate are fixed by bolts that pass through the panel, are screwed to the connecting studs and pass through the stern sealing plate.

[0014] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the above-mentioned medium and high speed marine movable spoiler has an annular groove for the movement of an eccentric shaft on the side of the panel facing the back plate.

[0015] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the above-mentioned medium and high speed marine movable spoiler, wherein the bottom of the back plate has a through groove for the movable plate to pass through the back plate and the outside of the front plate.

[0016] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the above-mentioned medium and high speed marine movable spoiler, wherein the edge of the panel is bolted to the edge of the back plate.

[0017] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the above-mentioned medium and high speed marine movable spoiler has a rotary drive mechanism including a motor, and a rotating shaft is coaxially fixed on the motor shaft. The rotating shaft sequentially connects the stern seal plate and the back plate to form the power output end. A sleeve is fitted on the outer circumferential surface of the rotating shaft, and the inner circumferential surface of the sleeve is rotatably connected to the outer circumferential surface of the rotating shaft.

[0018] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the above-mentioned medium and high speed marine movable spoiler has several sealing rings between the inner circumferential surface of the sleeve near the motor and the outer circumferential surface of the rotating shaft.

[0019] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the above-mentioned medium and high speed marine movable spoiler has a flange fixedly provided on the outer circumferential surface of the sleeve away from the motor, and the flange is bolted to the side wall of the back plate.

[0020] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the above-mentioned medium and high speed marine movable spoiler has an external thread on the outer circumferential surface of the sleeve, and several nuts that can be screwed to the external thread are also provided on the outer circumferential surface of the sleeve.

[0021] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0022] (1) By driving the eccentric disk and eccentric shaft through the rotary drive mechanism, the movable plate can be moved quickly and accurately vertically, thereby effectively adjusting the pitch, roll, trim and heel of the ship and improving the ship's motion attitude. Compared with the traditional hydraulic control, the structure of this medium and high speed marine movable spoiler is more compact, occupies less space, and has stronger adaptability. It is especially suitable for the stern sealing plate area of ​​ships with limited space.

[0023] (2) The design of connecting studs and guide grooves between the back plate, front plate and movable plate not only facilitates installation and disassembly, but also ensures the stability of the structure. The use of bolt fasteners further enhances the connection strength of the overall structure, ensuring the stable operation of the spoiler in harsh sea conditions.

[0024] (3) A sealing ring is set between the sleeve and the shaft of the rotary drive mechanism, which effectively prevents the intrusion of moisture and impurities, improves the durability and reliability of the equipment. At the same time, the sleeve is pressed against the stern sealing plate by the nut, which further enhances the sealing effect.

[0025] (4) The annular groove on the panel provides enough space for the movement of the eccentric shaft, so that the movable plate can move smoothly vertically. The through groove on the back plate ensures that the movable plate can extend completely beyond the back plate and the panel, achieving a wider turbulence effect. Attached Figure Description

[0030] The specific technical solutions of this utility model are further described below with reference to the accompanying drawings, so as to enable those skilled in the art to further understand this utility model, without constituting a limitation on its rights.

[0031] Example 1, referring to Figure 1-3 A medium-to-high speed marine movable spoiler, which is installed on the stern seal plate 1, has the following characteristics:

[0032] The back plate 2 is detachably fixed to the stern sealing plate 1, forming a roughly square plate structure. The back plate 2 is through the middle. Several connecting studs 3 are vertically fixed on the side of the back plate 2 facing the panel. Several guide grooves 5 are vertically opened on the movable plate 4 for the connecting studs 3 to extend out. The guide grooves 5 can be waist-shaped grooves. The panel 6, back plate 2 and stern sealing plate 1 are fixed by bolts that pass through the panel 6, are screwed to the connecting studs 3 and pass through the stern sealing plate 1. The number of studs 3 can be selected according to the usage requirements, for example, four studs.

[0033] It should be noted that the stud 3 can limit the left and right tilt of the movable plate 4 below, and can also connect the back plate 2 and the front panel 6 below.

[0034] Panel 6, which is detachably fixed to back plate 2, is formed into a roughly square plate structure, specifically by bolt connection. The center of panel 6 is through, and the edges of panel 6 are bolted to the edges of back plate 2.

[0035] A rotary drive mechanism is located on the inner and outer sides of the stern sealing plate 1, respectively, along with the back plate 2. The power output end of the rotary drive mechanism passes through the stern sealing plate 1 and the back plate 2 in sequence. An eccentric disk 7 is fixedly provided on the power output end of the rotary drive mechanism. The eccentric disk 7 is placed between the back plate 2 and the panel 6. An eccentric shaft 8 is axially fixed on the eccentric disk 7. An annular groove 9 for the eccentric shaft 8 to move is opened on the side of the panel 6 facing the back plate 2. The bottom of the back plate 2 has a through groove for the movable plate 4 to reach the outside of the back plate 2 and the panel 6. The through groove can be a square groove structure.

[0036] The rotary drive mechanism includes a motor 10, which uses a high-torque DC reducer as the drive source. A rotating shaft 11 is coaxially fixed on the motor shaft 10. The rotating shaft 11 forms the power output end by sequentially connecting the stern sealing plate 1 and the back plate 2. A sleeve 12 is fitted on the outer circumferential surface of the rotating shaft 11, and the inner circumferential surface of the sleeve 12 is rotatably connected to the outer circumferential surface of the rotating shaft 11. This can be achieved through bearings, but the rotatable connection method is not limited to this. Several seals are provided between the inner circumferential surface of the sleeve 12 near the motor 10 and the outer circumferential surface of the rotating shaft 11. The sealing ring can be made of multiple O-rings or multiple Glyd rings to achieve structural watertightness under the premise of torque transmission. A flange 13 is fixed on the outer circumference of the sleeve 12 away from the motor 10. The flange 13 is bolted to the side wall of the back plate 2. An external thread is provided on the outer circumference of the sleeve 12. Several nuts that can be screwed to the external thread are also provided on the outer circumference of the sleeve 12. The stern sealing plate 1 is located between the nuts and the flange 13. The nuts screwed to the external thread press the end of the sleeve 12 with the flange 13 onto the stern sealing plate 1.

[0037] It should be noted that the built-in motor 10, rotating shaft 11, eccentric shaft 8 and eccentric disk 7 are linked together to drive the movable plate 4 with the drive groove to move up and down, thus realizing the vertical movement of the single plate.

[0038] A movable plate 4 is also provided between the back plate 2 and the front plate 6. The movable plate 4 is formed into a roughly square plate structure. The top of the movable plate 4 is provided for the eccentric shaft 8 to pass through. When the eccentric shaft 8 moves, the movable plate 4 moves vertically to the drive groove 14 outside the back plate 2 and the front plate 6. The drive groove 14 is a horizontally set waist-shaped groove. The drive groove 14 and the eccentric shaft 8 roll and rub against each other. The friction is small, which reduces the probability of the mechanism jamming and can improve its reliability.

[0039] In addition, to improve the smoothness of the vertical movement of the movable plate 4, a sliding rail slider structure can be added between the movable plate 4, the back plate 2, and the front panel 6, so that the movement of the movable plate 4 is smoother and more stable.

[0040] When the movable plate 4 needs to be released, the rotary drive mechanism can drive the eccentric disk 7 to rotate, and the eccentric shaft 8 on the eccentric disk 7 pushes the waist-shaped groove to move vertically, thereby extending it from between the panel 6 and the back plate 2.
