Detailed Implementation

[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0050] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, and "at least one" can mean one, two, or more, unless otherwise explicitly specified.

[0051] With the booming development of shipbuilding and civil shipping, the vibration problem of ship structures has attracted increasing attention. Vibration phenomena in ship structures are very common, including vibrations caused by water currents during navigation, vibrations caused by the operation of engines, gearboxes, and hydraulic pumps, vibrations caused by ship piping systems, and vibrations caused by the engine's intake and exhaust systems. These vibrations make ships easily detectable by sonar during navigation, cause noise pollution to marine life, and if the natural frequency of the ship's vibration is the same as the natural frequency of a local structure, resonance will occur, leading to fatigue damage and affecting the overall stability of the ship's structure. Vibration also affects the performance and reliability of shipboard instruments and equipment.

[0052] Currently, vibration on pipelines is generally controlled using vibration-absorbing devices (which are electromagnetic actuators; their working principle is that the electromagnetic actuator generates a magnetic field through an electromagnetic coil. When current passes through the coil, the magnetic field applies an electromagnetic force to the mover, pushing or pulling it to achieve mechanical movement). The vibration-absorbing device generates a force at its designated location that is equal in amplitude but opposite in phase to the vibration signal, thereby counteracting the vibration at the target point. However, the force generated by the vibration-absorbing device cannot be adjusted according to the pipeline's vibration frequency, and the output force generated during the movement of the mover inside the device is not transmitted smoothly enough.

[0053] In view of this, embodiments of this application provide a vibration-absorbing device to overcome at least one of the above-mentioned technical problems.

[0054] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment of the application, the vibration absorption device includes a shell assembly 10, a moving part assembly 20, and an elastic component 30.

[0055] The shell assembly 10 has a receiving cavity 11. The mover assembly 20 is disposed within the receiving cavity 11 and has a mounting cavity 21. The elastic assembly 30 includes an elastic portion 31 and a pressing portion 32. The elastic portion 31 is disposed within the mounting cavity 21 and connected to the mover assembly 20. At least a portion of the pressing portion 32 is disposed within the mounting cavity 21 and connected to both the elastic portion 31 and the shell assembly 10. The pressing portion 32 is used to move along the height direction X to press the elastic portion 31.

[0056] It is understood that the shell assembly 10 of the device includes two parts: a frame and a top cover. The frame has an internal cavity 11, and the top cover is located on top of the frame to seal the cavity 11, thus providing a certain degree of protection for the structure within the cavity 11 (e.g., Figure 1 As shown, Figure 1 (The top cover of the shell assembly 10 is not shown). Inside the receiving cavity 11, a mover assembly 20 and a stator assembly 50 are disposed. When the stator assembly 50 is energized and generates a magnetic field, it can apply an electromagnetic force to the mover assembly 20, causing the mover assembly 20 to reciprocate in the height direction X, thereby generating a certain force to counteract vibrations generated in the corresponding pipeline. A mounting cavity 21 is provided on the mover assembly 20, extending along the height direction X. There can be one or multiple mounting cavities 21. An elastic component 30 is disposed inside each mounting cavity 21, connecting the shell assembly 10 and the mover assembly 20. Specifically, the top cover of the shell assembly 10 can be connected to the support portion 24 of the mover assembly 20 via the elastic component 30. An elastic portion 31 on the elastic component 30 is disposed within the mounting cavity 21, and a pressing portion 32 on the elastic component 30 is at least partially embedded within the mounting cavity 21 and connected to the inner wall of the mounting cavity, allowing it to move along the height direction X within the mounting cavity 21. One end of the elastic part 31 along the height direction X can abut against the inner wall of the mounting cavity 21, and the other end of the elastic part 31 along the height direction X can be spaced apart from the pressing part 32, or it can be attached to the pressing part 32, or it can press against the pressing part 32. The state between the two depends on the height of the pressing part 32 in the height direction X. When the moving part assembly 20 moves along the height direction X, it will press the elastic part 31 on the elastic part assembly 30, causing the elastic part 31 to deform, thereby changing the movement frequency of the moving part assembly 20.

[0057] During operation, different pipelines may generate different vibration frequencies. When the moving part 20 moves along the height direction X, its motion frequency is affected by the elastic component 30. Therefore, for different vibration frequencies on different pipelines, the squeezing part 32 can be moved along the height direction X to adjust the squeezing force of the squeezing part 32 on the elastic part 31, thereby adjusting the deformation degree of the elastic part 31 and achieving the effect of adjusting the preload of the elastic part 31. Different preload degrees of the elastic part 31 result in different reciprocating frequencies of the moving part 20 along the height direction X. Therefore, the motion frequency of the moving part 20 along the height direction X can be adjusted by the elastic component 30, thus adapting to pipelines with different vibration frequencies and improving the applicability of the device.

[0058] Please see Figure 2 and Figure 4 In conjunction with the above embodiments, in some embodiments, the pressing part 32 includes a pressing block 321 and a connecting rod 322.

[0059] The pressure block 321 is disposed in the mounting cavity 21 and connected to the elastic part 31. The connecting rod 322 is at least partially disposed in the mounting cavity 21 and connected to the moving part assembly 20. The connecting rod 322 passes through the pressure block 321 and is connected to the pressure block 321. The connecting rod 322 is used to raise and lower the pressure block 321 so that the pressure block 321 presses the elastic part 31.

[0060] It is understood that the pressure block 321 on the extrusion section 32 can be disposed inside the mounting cavity 21. By adjusting the position of the pressure block 321 in the height direction X, the extrusion pressure of the pressure block 321 on the elastic part 31 can be adjusted, thereby adjusting the degree of deformation of the elastic part 31. The connecting rod 322 on the extrusion section 32 can penetrate the interior of the pressure block 321 along the height direction X and be connected to the pressure block 321. At the same time, the connecting rod 322 can be a screw structure, which is connected to the mover assembly 20 by threads. Rotating the connecting rod 322 can move the connecting rod 322 in the height direction X, thereby driving the pressure block 321 to move in the height direction X, thereby adjusting the extrusion pressure of the pressure block 321 on the elastic part 31. The connecting rod 322 and the moving part assembly 20 can also be connected by equally spaced teeth or buckle structures, so that the connecting rod 322 can move along the height direction X and can be limited to a certain extent, so that the connecting rod 322 can drive the pressure block 321 to squeeze the elastic part 31 in the height direction X.

[0061] Please see Figure 2 and Figure 3In conjunction with the above embodiments, in some embodiments, the shell assembly 10 has a first groove 12, and the pressing part 32 passes through the bottom wall of the first groove 12 to the mounting cavity 21; the elastic component 30 also includes a cover part 33, which covers the first groove 12 and is connected to the shell assembly 10.

[0062] Understandably, a first groove 12 is provided on the shell assembly 10. Specifically, the first groove 12 can be provided on the upper cover of the shell assembly 10. The pressing part 32 can pass through the bottom wall of the first groove 12 and be embedded into the interior of the mounting cavity 21, so that the top end of the pressing part 32 can be located inside the first groove 12. The cover part 33 can seal the first groove 12, which can reduce the probability of foreign objects falling into the first groove 12. At the same time, it can also prevent the top end of the pressing part 32 from being accidentally rotated, causing the pre-tightening degree of the elastic part 31 to change, thus providing a certain degree of protection for the pressing part 32.

[0063] Please see Figure 2 and Figure 5 In conjunction with the above embodiments, in some embodiments, the mover assembly 20 has a through hole 22 communicating with the receiving cavity 11; the vibration damping device further includes a bearing assembly 40, which passes through the through hole 22 and is connected to the housing assembly 10, and the bearing assembly 40 is used to guide the mover assembly 20.

[0064] Understandably, through holes 22 can be provided along the height direction X on the mover assembly 20. The number of through holes 22 can be one or more. Each through hole 22 houses a bearing assembly 40, the top and bottom of which are connected to the housing assembly 10. The housing assembly 10 can guide the movement of the mover assembly 20 in the height direction X, preventing it from moving in a direction inclined to the height direction X, thus ensuring the smoothness of the mover assembly 20's movement.

[0065] Connecting the bearing assembly 40 and the elastic assembly 30 to the mover assembly 20 allows the force generated by the mover assembly 20 during movement to be smoothly transmitted to the corresponding pipeline, thereby improving the vibration absorption effect.

[0066] Please see Figure 2 , Figure 5 and Figure 6 In conjunction with the above embodiments, in some embodiments, the mover assembly 20 has a stepped groove 23 communicating with the through hole 22. The bearing assembly 40 includes a bushing portion 41 and a shaft body portion 42. The bushing portion 41 is disposed within the stepped groove 23 and is connected to the mover assembly 20. The shaft body portion 42 passes through the bushing portion 41 and the through hole 22, and is slidably connected to the bushing portion 41.

[0067] Understandably, the mover assembly 20 is also provided with stepped grooves 23, which are located at both ends of the through hole 22 and communicate with it to facilitate the insertion of the bearing assembly 40. The bearing assembly 40 includes bushing portions 41, the number of which is the same as the number of stepped grooves 23. Each stepped groove 23 has a bushing portion 41 inside, and the bushing portion 41 is connected to the inner wall of the stepped groove 23 by bolts. The shaft body portion 42 passes through the interior of the bushing portion 41 and the interior of the through hole 22, and both ends of the shaft body portion 42 are connected to the housing assembly 10 to ensure the stability of the shaft body portion 42 installation. The bushing portion 41 and the shaft body portion 42 can slide relative to each other in the height direction X, so that the mover assembly 20 connected to the bushing portion 41 can also slide relative to the shaft body portion 42 in the height direction X. By using the bushing portion 41 and the shaft body portion 42 together, the stability of the mover assembly 20 in the height direction X can be improved, and the risk of the mover assembly 20 shifting position during movement can be reduced.

[0068] Please see Figure 2 and Figure 3 In conjunction with the above embodiments, in some embodiments, the shell assembly 10 has a second groove 13 communicating with the receiving cavity 11; the bearing assembly 40 further includes a first fixing part 43 and a second fixing part 44.

[0069] One end of the shaft portion 42 is connected to the housing assembly 10 via the first fixing portion 43. The second fixing portion 44 includes a cover plate 441 and a locking pin 442. The cover plate 441 is disposed in the second groove 13, and the cover plate 441 is connected to the other end of the shaft portion 42 via the locking pin 442.

[0070] Understandably, to ensure the stability of the shaft portion 42, the bottom end of the shaft portion 42 can be connected to the housing assembly 10 via a first fixing part 43. The first fixing part 43 can be a bolt structure, which can stably connect the bottom end of the shaft portion 42 to the housing assembly 10. The top end of the shaft portion 42 is connected to the housing assembly 10 via a second fixing part 44 to further improve the stability of the shaft portion 42. The shaft portion 42 includes a cover plate 441 and a locking pin 442. The cover plate 441 is disposed in the second groove 13 on the housing assembly 10, and the cover plate 441 and the top end of the shaft portion 42 are connected by the locking pin 442, thereby ensuring the stability of the top end of the shaft portion 42.

[0071] Please see Figure 2 , Figure 3 and Figure 6 In conjunction with the above embodiments, in some embodiments, the shell assembly 10 has a positioning groove 14 communicating with the through hole 22, and the shaft part 42 passes through the through hole 22 into the positioning groove 14 and is connected to the shell assembly 10.

[0072] It is understood that a positioning groove 14 can be provided on the housing assembly 10, and the position of the positioning groove 14 corresponds to the end position of the shaft part 42. When the shaft part 42 is installed, its top or bottom end can be embedded into the corresponding positioning groove 14 to ensure the accuracy of the installation position of the shaft part 42 and prevent it from shifting during the installation process. The positioning groove 14 can be provided on the bottom wall of the receiving cavity 11, so that the bottom end of the shaft part 42 is embedded into the positioning groove 14 to achieve the positioning effect of the shaft part 42; the positioning groove 14 can also be provided on the top wall of the receiving cavity 11, so that the top end of the shaft part 42 is embedded into the positioning groove 14, which can also achieve the positioning of the shaft part 42.

[0073] Please see Figure 1 and Figure 7 In conjunction with the above embodiments, in some embodiments, the mover assembly 20 includes a support portion 24 and two magnet portions 25.

[0074] A support portion 24 is disposed within the receiving cavity 11. The support portion 24 has first placement grooves 241 on both sides in the width direction Y, and also has a mounting cavity 21. Two magnet portions 25 are respectively disposed within the corresponding first placement grooves 241 and connected to the support portion 24. The width direction Y intersects the height direction X; preferably, the width direction Y and the height direction X are perpendicular to each other.

[0075] Understandably, the mover assembly 20 includes a support portion 24, which has through holes 22 along the height direction X. The support assembly 40 passes through the corresponding through holes 22, allowing the support portion 24 to move along the height direction X. The support portion 24 has first placement grooves 241 on both sides of its width direction Y. Each first placement groove 241 contains a magnet portion 25, which can be glued to the inner wall of the first placement groove 241 to ensure its stability. Under the action of the stator assembly 50, an electromagnetic force is generated on the magnet portion 25, causing it to move the support portion 24 along the height direction X.

[0076] Please see Figure 1 and Figure 7 In conjunction with the above embodiments, in some embodiments, the vibration absorption device further includes a stator assembly 50, which includes two silicon steel sections 51 and a coil section 52.

[0077] Two silicon steel portions 51 are respectively disposed on both sides of the mover assembly 20 in the width direction Y and connected to the housing assembly 10. The silicon steel portions 51 have a second placement groove 511. A coil portion 52 is disposed around the mover assembly 20, passes through the second placement groove 511, and is connected to the silicon steel portions 51.

[0078] Understandably, the stator assembly 50 of the vibration damping device is arranged around the rotor assembly 20. Two silicon steel portions 51 on the stator assembly 50 are positioned on both sides of the rotor assembly 20 along the width direction Y. A second placement groove 511 is formed on the side of the silicon steel portion 51 facing the rotor assembly 20. When arranging the coil portion 52 on the stator assembly 50, the coil portion 52 can be arranged to pass through the corresponding second placement groove 511 while surrounding the rotor assembly 20, and is connected to the inner wall of the second placement groove 511 by adhesive. This arrangement of passing through the second placement groove 511 reduces the space occupied by the coil portion 52 within the receiving cavity 11, improves space utilization, and avoids increasing the size of the vibration damping device.

[0079] After the two silicon steel parts 51 are installed inside the receiving cavity 11, gaskets 80 can be placed on top of them. The gaskets 80 can be squeezed by the top cover on the housing assembly 10, so that the gaskets 80 squeeze the silicon steel parts 51, thereby pressing the silicon steel parts 51 tightly inside the receiving cavity 11 and improving the stability of the silicon steel parts 51 during use.

[0080] Please see Figure 8 and Figure 9 In conjunction with the above embodiments, the pipeline system in this application includes a pipe body 60, a connecting assembly 70, and the vibration-absorbing device mentioned above.

[0081] The connecting assembly 70 includes a surrounding portion 71 and a flexible portion 72. The flexible portion 72 is arranged circumferentially around the tube body 60 and connected to the tube body 60. The surrounding portion 71 is arranged circumferentially around the flexible portion 72 and connected to the flexible portion 72. A vibration damping device is provided on at least one side of the surrounding portion 71.

[0082] It is understandable that when the vibration-absorbing device is connected to the tube body 60, a connecting assembly 70 can be first installed on the tube body 60, with the connecting assembly 70 surrounding the tube body 60. Then, a vibration-absorbing device can be installed on one side of the connecting assembly 70, or vibration-absorbing devices can be installed on multiple sides of the connecting assembly 70. Preferably, multiple vibration-absorbing devices are arranged around the connecting assembly 70. The movement direction of the moving part assembly 20 on the vibration-absorbing device is perpendicular to the axial direction of the tube body 60. The flexible part 72 on the connecting component 70 can be wrapped around the tube body 60 (the flexible part 72 can be a flexible structure such as rubber or silicone). Then, the surrounding part 71 on the connecting component 70 is arranged around the flexible part 72 (the surrounding part 71 can be composed of two structures with semi-circular inner sides. After the two are connected, the inner sides just form a circular structure, which is convenient to wrap around the surface of the flexible part 72). The flexible part 72 is arranged between the surrounding part 71 and the tube body 60, which can make the connection between the surrounding part 71 and the tube body 60 tighter, which can facilitate the transmission of the force on the vibration absorption device to the tube body 60 and improve the vibration absorption effect.

[0083] Please see Figure 9 , Figure 10 and Figure 11 In conjunction with the above embodiments, in some embodiments, the surrounding portion 71 includes a first connecting block 711 and a second connecting block 712 connected together. The inner sides of both the first connecting block 711 and the second connecting block 712 have semi-circular spaces. When the inner sides of the first connecting block 711 and the second connecting block 712 are connected relative to each other, the two semi-circular spaces form a circular fixing cavity 717 (that is, the first connecting block 711 and the second connecting block 712 enclose and form the fixing cavity 717). The tube body 60 can pass through this fixing cavity 717, allowing the surrounding portion 71 to be installed on the tube body 60. During the processing of the surrounding portion 71, the structural dimensions of the surrounding portion 71 can be flexibly changed, such as changing the inner diameter of the fixing cavity 717. Since the fixing cavity 717 is a circular structure, its inner diameter can be changed by altering the wall thickness during processing. This allows it to adapt to tube bodies 60 of different diameters on ships, facilitating the installation of the surrounding portion 71 on tube bodies 60 of different diameters and improving the applicability of the project.

[0084] Multiple first connecting holes 713 are provided on the first connecting block 711. The first connecting holes 713 are generally located on the side of the first connecting block 711 opposite to the second connecting block 712, or on the side of the first connecting block 711 facing the second connecting block 712, and extend through the entire first connecting block 711 in that direction. Similarly, multiple second connecting holes 714 are provided on the second connecting block 712.
