Description

[0002] Elbows are commonly used components in marine steam propulsion systems, connecting and arranging various flow devices within confined compartments. They are indispensable to these systems. However, due to their structural characteristics, elbows can cause uneven distribution of the working fluid's velocity and create complex secondary flows. These flow characteristics result in total fluid pressure and energy loss, which is then emitted as noise, significantly impacting system performance. Currently, vibration and noise reduction in elbow components during system operation is often achieved by fixing guide vanes or selecting elbows of specific diameters. These methods are relatively limited, have narrow applicability, and cannot adequately address the vibration and noise reduction requirements under various operating conditions.

This device features a first magnetic linkage device and a second magnetic linkage device at the bend inlet and outlet, respectively, along with a transmission mechanism connecting the two devices. When the fluid flows through the first magnetic linkage device from the bend inlet, some of its kinetic energy drives the device to rotate. This converts some of the fluid's kinetic energy into mechanical energy, which is then transferred to the second magnetic linkage device via the transmission mechanism. This reduces the flow velocity of the fluid passing through the first magnetic linkage device, thereby reducing the impact and radiated noise caused by flow-induced vibration as the fluid passes through the bend. The transferred energy is returned to the fluid via the second magnetic linkage device. In other words, the rotation of the second magnetic linkage device pressurizes and accelerates the decelerated fluid, allowing it to return to normal flow velocity and pressure after passing through the bend at low speed, ensuring the normal operation of subsequent processes.

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0029] The following is combined Figures 1 to 3 The present invention provides a detailed description of the vibration reduction and noise reduction device for fluid bends based on magnetic linkage energy migration.

[0030] Please see Figure 1 The magnetic linkage energy transfer fluid bend vibration reduction and noise reduction device of the present invention includes a first magnetic linkage device 2, a second magnetic linkage device 3 and a transmission mechanism 4. The first magnetic linkage device 2 is sleeved at the inlet of the bend 1, and the second magnetic linkage device 3 is sleeved at the outlet of the bend 1. The first magnetic linkage device 2 and the second magnetic linkage device 3 are connected by transmission mechanism 4.

[0031] It is understood that bend 1 is a pipe with a certain bending angle, such as a pipe with a 90° bending angle, but it is not limited to this.

[0032] The working fluid (such as water) flows from the inlet side of the bend 1 to the outlet side of the bend 1. When the working fluid flows through the first magnetic linkage device 2, the first magnetic linkage device 2 will rotate with the flow of the working fluid. The rotation of the first magnetic linkage device 2 is transmitted through the transmission mechanism 4 and drives the second magnetic linkage device 3 to rotate. The second magnetic linkage device 3 pressurizes and accelerates the working fluid flowing through the second magnetic linkage device 3 by rotating. In other words, when the working fluid flows from the inlet of the bend 1 through the first magnetic linkage device 2, part of the kinetic energy of the working fluid can drive the first magnetic linkage device 2 to rotate. That is, part of the kinetic energy of the working fluid is converted into the mechanical energy of the first magnetic linkage device 2 and transferred to the second magnetic linkage device 3 through the transmission mechanism 4. This reduces the flow velocity of the working fluid flowing through the first magnetic linkage device 2, thereby reducing the impact force and radiated noise caused by the flow-induced vibration when the working fluid flows through the bend 1. The transferred energy can be returned to the working fluid through the second magnetic linkage device 3. That is, the second magnetic linkage device 3 can pressurize and accelerate the decelerated working fluid by rotating, so that the working fluid can restore normal flow velocity and pressure after passing through the bend at low speed, ensuring the normal operation of subsequent processes.

[0033] Please see Figure 2 The first magnetic linkage device 2 includes a first magnetic rotation assembly 21 located inside the bend 1 and a second magnetic rotation assembly 22 located outside the bend 1. The second magnetic rotation assembly 22 is located around the first magnetic rotation assembly 21 and is connected to one end of the transmission mechanism 4. A magnetic field is formed between the first magnetic rotation assembly 21 and the second magnetic rotation assembly 22. The first magnetic rotation assembly 21 rotates with the flow of the fluid working medium, and due to the interaction of the magnetic fields, the second magnetic rotation assembly 22 rotates synchronously with the rotation of the first magnetic rotation assembly 21. The rotation direction of the second magnetic rotation assembly 22 is the same as that of the first magnetic rotation assembly 21.

[0034] Specifically, the first magnetic rotation assembly 21 is coaxially arranged with the inlet end of the bend 1, and is rotatably mounted on the inner wall of the bend 1. The first magnetic rotation assembly 21 includes multiple first rotating blades 211, multiple first magnetic bases 212, and a first fixing ring 213. The multiple first magnetic bases 212 are all magnetic, and are fixedly mounted on the first fixing ring 213 at intervals along the circumferential direction of the inner wall of the bend 1. The first fixing ring 213 is used to fix the multiple first magnetic bases 212, ensuring a certain distance between them and that they are located on the same plane. The multiple first rotating blades 211 are fixedly mounted one-to-one on the side of the multiple first magnetic bases 212 facing away from the bend 1. The flow of the fluid working medium can drive the multiple first rotating blades 211 in contact with the fluid working medium to rotate, and the rotation of the first rotating blades 211 can drive the multiple first magnetic bases 212 to rotate synchronously.

[0035] The multiple first rotating blades 211 are set at a certain tilt angle, so that the flow rate of the fluid working medium decreases after flowing through the first rotating blades 211. The specific tilt angle can be set according to the actual use.

[0036] Furthermore, the first magnetic linkage device 2 also includes a first guide groove 23 fixedly installed on the inner wall of the bend 1. The first guide groove 23 is an annular structure coaxial with the inlet end of the bend 1. Multiple first magnetic bases 212 are slidably installed on the first guide groove 23. The first guide groove 23 has a guiding function, so that the first magnetic rotation component 21 rotates circumferentially along the inner wall of the bend 1.

[0037] The second magnetic rotation assembly 22 is coaxial with the first magnetic rotation assembly 21 and is arranged around the bent pipe 1. The second magnetic rotation assembly 22 includes multiple second magnetic bases 221, multiple first transmission teeth 222, and a second fixing ring 223. The multiple second magnetic bases 221 are all magnetic, and are fixedly mounted on the second fixing ring 223 at intervals along the circumferential direction of the outer wall of the bent pipe 1. The second fixing ring 223 is used to fix the multiple second magnetic bases 221, ensuring that the multiple second magnetic bases 221 maintain a certain distance from each other and are located on the same plane. The multiple first transmission teeth 222 are fixedly mounted one-to-one on the side of the multiple second magnetic bases 211 facing away from the bent pipe 1, and the multiple first transmission teeth 222 rotate synchronously with the multiple second magnetic bases 221.

[0038] Furthermore, a first air medium layer 24 is provided between the second magnetic rotation component 22 and the bend 1, and the first air medium layer 24 is arranged around the bend 1. That is, the second magnetic rotation component 22 and the bend 1 are designed to be non-contact. Under the interaction of the magnetic field, the second magnetic rotation component 22 rotates with the rotation of the first magnetic rotation component 21. Since the second magnetic rotation component 22 and the bend 1 have no mechanical contact, the energy consumption during the energy transfer process can be reduced.

[0039] Please see Figure 3 The second magnetic linkage device 3 includes a third magnetic rotation assembly 31 located inside the bend 1 and a fourth magnetic rotation assembly 32 located outside the bend 1. The fourth magnetic rotation assembly 32 is located around the third magnetic rotation assembly 31 and is connected to the other end of the transmission mechanism 4. The rotation of the second magnetic rotation assembly 32 can drive the fourth magnetic rotation assembly 32 to rotate via the transmission mechanism 4. A magnetic field is formed between the third magnetic rotation assembly 31 and the fourth magnetic rotation assembly 32. Due to the interaction of the magnetic fields, the third magnetic rotation assembly 31 rotates synchronously with the fourth magnetic rotation assembly 32. The rotation directions of the third magnetic rotation assembly 31 and the fourth magnetic rotation assembly 32 are the same.

[0040] Specifically, the third magnetic rotation assembly 31 is coaxially arranged with the outlet end of the bend 1, and is rotatably mounted on the inner wall of the bend 1. The third magnetic rotation assembly 31 includes multiple second rotating blades 311, multiple third magnetic bases 312, and a third fixing ring 313. All of the multiple third magnetic bases 312 are magnetic, and are fixedly mounted on the third fixing ring 313 at circumferential intervals along the inner wall of the bend 1. The third fixing ring 313 is used to fix the multiple third magnetic bases 312, so that the multiple...

[0041] The third magnetic bases 312 are spaced apart and located on the same plane. Multiple second rotating blades 311 are fixedly mounted one-to-one on the side of the multiple third magnetic bases 312 facing away from the bend 1. When the third magnetic rotation assembly 31 rotates, the mechanical energy of the multiple second rotating blades 311 can be transferred to the fluid working medium, that is, the multiple second rotating blades 311 can pressurize and accelerate the fluid working medium flowing through the second magnetic linkage device 3.

[0042] The multiple second rotating blades 311 are set at a certain tilt angle, so that the second rotating blades 311 can push the fluid working medium to flow along the flow direction, thereby increasing the flow velocity of the fluid working medium. The specific tilt angle can be set according to the actual use.

[0043] Furthermore, the second magnetic linkage device 3 also includes a second guide groove 33 fixedly installed on the inner wall of the bend 1. The second guide groove 33 is an annular structure coaxial with the outlet end of the bend 1. Multiple third magnetic bases 312 are slidably installed on the second guide groove 33. The second guide groove 33 has a guiding function, so that the third magnetic rotation component 31 rotates circumferentially along the inner wall of the bend 1.

[0044] The fourth magnetic rotation assembly 32 is coaxial with the third magnetic rotation assembly 31 and surrounds the bent pipe 1. The fourth magnetic rotation assembly 32 includes multiple fourth magnetic bases 321, multiple second transmission teeth 322, and a fourth fixing ring 323. The multiple fourth magnetic bases 321 are all magnetic, and are fixedly mounted on the fourth fixing ring 323 at intervals along the circumferential direction of the outer wall of the bent pipe 1. The fourth fixing ring 323 is used to fix the multiple fourth magnetic bases 321, ensuring that the multiple fourth magnetic bases 321 maintain a certain distance from each other and are located on the same plane. The multiple second transmission teeth 322 are correspondingly mounted on the side of the multiple fourth magnetic bases 321 facing away from the bent pipe 1, and rotate synchronously with the multiple fourth magnetic bases 321.

[0045] Furthermore, a second air medium layer 34 is provided between the fourth magnetic rotation component 32 and the bend 1, and the second air medium layer 34 is arranged around the bend 1. That is, the fourth magnetic rotation component 32 and the bend 1 are non-contact designs. Since the fourth magnetic rotation component 32 and the bend 1 have no mechanical contact, the energy consumption during the energy transfer process can be reduced.

[0046] Please continue reading. Figure 1 The transmission mechanism 4 includes a first transmission shaft 41, a second transmission shaft 42, a reversing gear assembly 43, a first transmission gear 44, and a second transmission gear 45. One end of the first transmission shaft 41 is connected to one end of the second transmission shaft 42 through the reversing gear assembly 43. The first transmission gear 44 is fixedly installed at the other end of the first transmission shaft 41 and meshes with the first transmission gear of the first magnetic linkage device 2. The second transmission gear 45 is fixedly installed at the other end of the second transmission shaft 42 and meshes with the second transmission gear of the second magnetic linkage device 3.

[0047] In this embodiment, the first drive shaft 41 and the second drive shaft 42 are arranged perpendicular to each other. The first drive shaft 41 is arranged parallel to the inlet end of the bend 1, and the second drive shaft 42 is arranged parallel to the outlet end of the bend 1.

[0048] Furthermore, the reversing gear assembly 43 includes a first reversing gear (not shown) and a second reversing gear (not shown) that mesh with each other. The first reversing gear is coaxially arranged with the first drive shaft 41 and is fixedly connected to the first drive shaft 41. The second reversing gear is coaxially arranged with the second drive shaft 42 and is fixedly connected to the second drive shaft 42.

[0049] Combination Figures 1 to 3As shown, the working principle of the magnetic linkage energy transfer fluid bend vibration reduction and noise reduction device of the present invention is as follows: When the fluid working medium in the pipeline flows through the first magnetic linkage device 2, the fluid working medium impacts the first rotating blade 211 on the first magnetic linkage device 2. The first rotating blade 211 drives the first magnetic base 212 of the inner ring of the first magnetic linkage device 2 to rotate. During this process, part of the kinetic energy of the fluid working medium is converted into the mechanical energy of the first magnetic base 212. The flow velocity of the fluid working medium decreases, and it can pass through the bend 1 in a laminar or low turbulence state, which greatly reduces the influence of the bend structure on the flow of the working medium, reduces the generation of complex flow patterns such as secondary flow in the bend 1, reduces the radiated noise caused by the impact and flow-induced vibration when the fluid working medium flows through the bend 1, and improves the acoustic performance of the bend component of the steam-water circulation loop. On the other hand, due to the interaction of magnetic fields, the rotating first magnetic base 212 drives the outer ring second magnetic base 221 to rotate together. The second magnetic base 221 meshes with the first transmission gear 44 through the first transmission tooth 222, and drives the first transmission gear 44 and the first transmission shaft 41 to rotate synchronously. The first transmission shaft 41 is connected to the reversing gear assembly 43. The first transmission shaft 41 drives the second transmission shaft 42 perpendicular to it to rotate. The second transmission shaft 42 drives the fourth magnetic base 321 of the outer ring of the second magnetic linkage device 3 to rotate through the second transmission gear 45 set at the outlet of the bend. Similarly, the interaction of magnetic fields causes the third magnetic base 312 of the inner ring of the second magnetic linkage device 3 to rotate. The second rotating blade 311 on the second magnetic linkage device 3 can pressurize and accelerate the fluid working medium that is slowed down by the first rotating blade 211, so that the fluid working medium can restore its flow rate and pressure after passing through the bend at low speed, ensuring the normal operation of the subsequent steam-water circulation.

[0050] As can be seen from the above, the noise reduction device of the present invention transfers the kinetic energy of the fluid working medium at the inlet of the bend through a rotor and magnetic components, reducing the velocity of the fluid working medium as it passes through the bend, thereby weakening the influence of the bend on the flow process. Simultaneously, the transferred energy is returned to the fluid working medium at the outlet of the bend, restoring its flow velocity and pressure, ensuring its normal operation in subsequent systems. While some energy loss is unavoidable during energy transfer, compared to the energy dissipation caused by the high-speed flow through the bend leading to flow-induced oscillations and higher noise levels, the improvement in the hydraulic and acoustic performance of the system introduced by the noise reduction device of the present invention still has high engineering application value, especially in terms of system vibration reduction and noise reduction.

[0051] This invention employs a magnetically linked energy transfer vibration reduction and noise reduction device that automatically adjusts its rotational speed according to the velocity of the fluid working medium within the pipeline. Compared to traditional fixed guide vane rectification, this noise reduction device is more adaptable and can meet the needs of speed reduction and rectification of the fluid working medium in bends under different operating conditions. Secondly, the noise reduction device of this invention completes energy transfer through magnetic field action, without mechanical contact, thus reducing energy consumption during the energy transfer process compared to general gear transmission. In addition, the components of this noise reduction device do not require welding, making them easy to disassemble, inspect, and replace, resulting in lower maintenance costs and greater applicability.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
