Description

Technical Field

[0001] This invention belongs to the field of pipeline vibration control technology, and specifically relates to a vibration control device for suspended pipelines. Background Technology

[0002] In recent years, with the continuous development of the oil and gas industry, more and more stations and offshore platforms are being built, and an increasing number of gathering and transportation pipelines are experiencing vibration problems during operation after construction. For pipelines close to the ground or other fixed installations, vibration reduction can be achieved by adding external supports. However, many suspended pipelines also suffer from vibrations that cannot be effectively addressed due to the lack of surrounding support devices. Furthermore, many publicly available patents related to pipeline vibration reduction rely primarily on fixing the locally vibrating parts of the pipeline and supporting them with other fixed surfaces, or altering the internal flow field to eliminate vibrations caused by flow patterns. However, these two methods are not suitable for gathering and transportation pipelines on suspended stations or offshore platforms, as they are difficult to construct and have low returns. Therefore, adopting reliable vibration reduction devices and self-fixing devices to protect suspended pipelines on station platforms is extremely important for the long-term safe service of gathering and transportation pipelines and for reducing operational and maintenance pressures. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a vibration control device for suspended pipelines, comprising a pipeline wrapping cylinder and a rubber ball; the pipeline wrapping cylinder wraps around the suspended pipeline, and a plurality of telescopic rods are connected between the pipeline wrapping cylinder and the rubber ball; one end of each telescopic rod is slidably connected to the outer surface of the rubber ball via an arc-shaped plate, and the other end of each telescopic rod is rotatably connected to the pipeline wrapping cylinder; magnetorheological fluid is disposed inside the rubber ball, and circuitry is disposed inside or outside the rubber ball.

[0004] Furthermore, the inner surface of the pipe wrapping cylinder is provided with a plurality of sequentially connected rubber arc plates along the axial direction, and the rubber arc plates are in contact with the suspended pipe.

[0005] Furthermore, a fixing ring is provided on the outer surface of the pipe wrapping cylinder, and the fixing ring is connected to the end of the telescopic rod.

[0006] Furthermore, the pipe wrapping cylinder is formed by joining the two ends of a rolled plate.

[0007] Furthermore, connecting rings are respectively provided on both ends of the outer surface of the coil.

[0008] Furthermore, the coil is made of rubber.

[0009] Furthermore, the rubber ball includes a first shell and a second shell, the second shell being located outside the first shell and having a groove formed on it; the first shell is a sealed shell and contains magnetorheological fluid inside; a slide rail is provided outside the first shell, and the slide rail is slidably connected to the arc-shaped plate.

[0010] Furthermore, the first housing and the second housing are joined by thermal fusion.

[0011] Furthermore, the vibration control device also includes a fixing plate, one end of which is rotatably connected to the end of the telescopic rod away from the rubber ball, and the other end is connected to the fixing ring by bolts.

[0012] Furthermore, the vibration control device also includes a fixed base, which is fixedly connected to the rubber ball.

[0013] Beneficial effects:

[0014] 1. This invention uses several telescopic rods connected between the pipe wrapping cylinder and the rubber ball to limit the movement of the suspended pipe. Simultaneously, by placing a magnetorheological fluid inside the rubber ball, a magnetic field is generated through an electrical circuit, causing the magnetorheological fluid to change its viscosity. The telescopic rods push the rubber ball to deform, and the resulting force acts on the magnetorheological fluid, hindering vibration, reducing amplitude and frequency, and thus reducing the vibration of the suspended pipe. This facilitates practical engineering applications, reduces the difficulty of maintenance and repair, and effectively improves the service life of the pipe.

[0015] 2. The present invention reduces the vibration of the suspended pipe by wrapping the suspended pipe with a rubber arc plate inside the pipe wrapping cylinder.

[0016] 3. The pipe wrapping cylinder of the present invention is formed by joining the two ends of a roll plate. Suspended pipes of different diameters are installed inside the pipe wrapping cylinder. The distance between the two ends of the roll plate is adjusted by adjusting the distance between the two corresponding connecting rings, thereby adapting to suspended pipes of different diameters.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0024] For collection and transportation pipelines that run in mid-air without intermediate support, making it inconvenient to connect with fixed structures, this invention can be applied to the straight and elbow sections of the suspended pipeline 1. This invention can be installed as a small structure near any local vibration location of the suspended pipeline 1, or it can be used for self-fixation (i.e., the horizontal section of the suspended pipeline 1 is connected to a rubber ball 8 by two or more sets of telescopic rods 6 to form a similar "triangle" fixing method). It only needs to be connected to the rubber ball 8 with a slide rail through the telescopic rods 6 and the connecting ring 5.

[0025] like Figure 1 As shown, Figure 1 A schematic diagram of the vibration control device for suspended pipelines in an embodiment of the present invention is shown. (Reference) Figure 1 A vibration control device for a suspended pipeline includes a pipeline wrapping cylinder 2 and a rubber ball 8. The pipeline wrapping cylinder 2 wraps around the suspended pipeline 1. Several telescopic rods 6 are connected between the pipeline wrapping cylinder 2 and the rubber ball 8. One end of the telescopic rod 6 is slidably connected to the outer surface of the rubber ball 8 through an arc plate 7, and the other end of the telescopic rod 6 is rotatably connected to the pipeline wrapping cylinder 2. A magnetorheological fluid 9 is provided inside the rubber ball 8, and a circuit is provided inside or outside the rubber ball 8. The circuit is connected to a power supply and a switch.

[0026] Specifically, the pipe wrapping sleeve 2 should be made of rubber, bendable and torsion-resistant, possess a certain degree of toughness, and not be too dense. The arc-shaped plate 7 should be made of steel, with smooth edges, and have at least two bolt holes for connecting the telescopic rod 6. The telescopic rod 6 can be adjusted in angle and length according to the pipe's suspended state and the amplitude and frequency of vibration.

[0027] This device helps to mitigate the vibration of the suspended pipe 1, provides support for the suspended pipe 1, increases the motion damping of the suspended pipe 1, and reduces the amplitude of the suspended pipe 1. It is highly applicable to suspended pipes 1 that are not suitable for support. When the suspended pipe 1 vibrates, the telescopic rod 6 pushes the rubber ball 8 to deform, and the force generated acts on the magnetorheological fluid 9 (because the viscosity of the magnetorheological fluid 9 changes after being energized), which hinders the vibration and reduces the amplitude frequency.

[0028] Damping and providing fixed support for the straight and curved sections of the suspended pipeline 1 can effectively reduce the vibration amplitude of the suspended pipeline 1, facilitate practical engineering applications, reduce the difficulty of maintenance and repair, and effectively improve the service life of the suspended pipeline 1.

[0029] Specifically, the telescopic rod 6 is a hydraulic rod, which should be composed of three hydraulic devices of different thicknesses. The thickest part is close to the vibrating suspended pipe 1, and the thinnest part is close to the rubber ball with the slide rail 81. It can extend and retract freely, and each part has enough length for connection.

[0030] Specifically, the arc-shaped plate 7 should be made of steel with smooth edges and at least two bolt holes for connecting the telescopic rod 6. The surface of the arc-shaped plate 7 must have a wear-resistant coating to ensure the service life of the workpiece. The arc-shaped plate 7 should have a certain rigidity, preferably made of steel, but its edges must be smooth and have a wear-resistant coating. It must also be able to slide normally on the slide rail 81. The arc-shaped plate 7 with bolt holes allows the direction of action of the telescopic rod 6 to be changed, better adapting to vibrations in different directions in the pipeline and giving the pipeline a certain degree of freedom.

[0031] refer to Figure 2 The pipe wrapping cylinder 2 is formed by rolling the plate 21 into a cylindrical shape, that is, by bending the plate 21 and then joining the left and right ends together.

[0032] Specifically, suspended pipes 1 of different diameters are installed inside the pipe wrapping cylinder 2, and the distance between the two opposite connecting rings 5 ​​is adjusted to adjust the distance between the two ends of the roll plate 21, so as to adapt to suspended pipes 1 of different diameters.

[0033] In this invention, a plurality of sequentially connected rubber arc-shaped plates 10 are arranged along the axial direction on the inner surface of the pipe wrapping cylinder 2, and the rubber arc-shaped plates 10 are in contact with the suspended pipe 1. Specifically, the rubber arc-shaped plates 10 are installed on the inner side of the pipe wrapping cylinder 2, such as... Figure 2 ,exist Figure 2 The rubber arc plate 10 is divided into four sections to wrap the suspended pipe 1. The suspended pipe 1 is used to transport oil and gas. The four rubber arc plates 10 and the suspended pipe 1 form a supporting function and are tightly connected to the pipe wrapping cylinder 2.

[0034] The pipe wrapping cylinder 2 is made entirely of rubber and has several fixing rings 4 and connecting rings 5, which are arranged sequentially along the axial direction of the pipe wrapping cylinder 2, with their through holes facing the radial direction of the pipe.

[0035] In the above embodiments, another optional implementation is that the rubber arc plate 10 and the pipe wrapping cylinder 2 are made of the same material. The rubber arc plate 10 is installed inside the pipe wrapping cylinder 2 and is tightly connected end to end. The rubber arc plate 10 must meet at least one-sixth of the arc length, and the protrusion height should not be too low. It is advisable to fully compress the suspended pipe 1 inside the pipe wrapping cylinder 2.

[0036] The plan view of the pipe wrapping tube 2 is as follows Figure 2 Except for the connecting ring 5 and the fixing ring 4, all are made of rubber material, and the rubber arc plates 10 are connected by heat fusion to ensure the overall consistency of the rubber material. The connecting ring 5 is distributed on both sides and can be covered according to different pipe shapes. Then, the connection and fixation are completed by bolts to ensure its sealing.

[0037] The suspended pipe 1 is wrapped with a rubber arc plate 10, which completes the first layer of damping for the suspended pipe 1. The combined action of rubber and air effectively reduces vibration. The rubber material of the pipe wrapping cylinder 2 allows it to completely cover the suspended pipe 1 at various angles, including straight pipes and bends.

[0038] In this invention, a fixing ring 4 is provided on the axis of the pipe wrapping cylinder 2, and the fixing ring 4 is connected to one end of the telescopic rod 6. Specifically, the fixing ring 4 should be made of steel, and the fixing ring 4 is installed on the outside of the pipe wrapping cylinder 2 along the axial direction of the suspended pipe 1, forming three rows, and is installed in any three of the four 90° included directions of the axial direction of the pipe wrapping cylinder 2.

[0039] The spacing between the fixing rings 4 should be small, but they should not touch each other when the pipe wrapping sleeve 2 bends. The spacing between the fixing rings 4 can be appropriately increased, but the connection stability of the device must be ensured and cracking must be avoided. The connection point of the fixing plate 3 can be freely selected through the fixing rings 4, and the installation position of the fixing plate 3 can be determined according to the actual vibration conditions.

[0040] The fixing ring 4 and the telescopic rod 6 are fixedly connected by bolts, and the fixing plate 3 and the telescopic rod 6 are rotatably connected, which helps the pipeline to form a self-fixing structure. This solves the problem of the suspended pipeline 1 having no effective support in the suspended position, and provides the suspended pipeline 1 with its own support point, thus reducing vibration to a certain extent. The positional spacing of the fixing ring 4 ensures that the pipeline wrapping cylinder 2 will not collide during bending, and effectively installs the fixing plate 3.

[0041] By selecting materials for the fixing plate 3, including steel and rubber, and choosing different materials according to different angles, a tight connection with the telescopic rod 6 is ensured. Several fixing rings 4 are used to fix the telescopic rod 6 to stabilize the device and support the suspended pipe 1.

[0042] In this invention, connecting rings 5 ​​are respectively provided on both ends of the outer surface of the roll plate 21. Specifically, the connecting rings 5 ​​are distributed on both sides, which can cover different pipe shapes, and then the connection and fixation are completed by bolts to ensure its sealing.

[0043] In this invention, the rolled plate 21 is made of rubber. The connecting ring 5 is installed on the outer axial direction of the pipe wrapping cylinder 2, at 90°, 90° and 180° angles with the fixing rings 4 respectively, and its size should be much larger than the fixing rings 4. Both the fixing rings 4 and the connecting ring 5 are designed with a rectangular plus semi-circular integral welded opening, and it is necessary to ensure that there is a certain distance between the opening and the boundary, and the direction of the through hole is directly opposite to the radial direction of the pipe.

[0044] refer to Figure 3 The rubber ball 8 includes a first shell 82 and a second shell 83. The second shell 83 is located outside the first shell 82 and has a groove. The first shell 82 is a sealed shell and contains magnetorheological fluid 9. A slide rail 81 is provided in the groove and is slidably connected to the arc plate 7.

[0045] Specifically, in the rubber ball 8, the first shell 82 contains a certain amount of magnetorheological fluid 9, and the first shell 82 has a slide rail 81 on its outside, on which the arc plate 7 with bolt holes is installed.

[0046] The rubber ball 8 should be made of the same material as the pipe wrapping tube 2. The first shell 82 is filled with magnetorheological fluid 9. The second shell 83 is closely attached to the outside of the first shell 82. There is a slide rail 81 on the outside of the first shell 82. The arc plate 7 is installed on the slide rail 81 to form a whole.

[0047] The first housing 82 and the second housing 83 inside the rubber ball 8 with the slide rail should be connected by heat fusion to ensure that they do not separate during deformation. The slide rail 81 is installed in the middle of the first housing 82 and should have a certain degree of elasticity and wear resistance.

[0048] The magnetorheological fluid 9 needs to be filled from inside the first housing 82, and it must be ensured that the rubber ball 8 does not leak after filling. After filling by needle injection, the magnetorheological fluid 9 is sealed inside the rubber ball 8 by heat fusion. The magnetorheological fluid 9 changes viscosity and increases damping when an external current is applied. The external current can be applied by ground power, the battery of the device, or vibration power generation, all of which are within the protection range.

[0049] In this invention, the first housing 82 and the second housing 83 are connected by heat fusion. Specifically, the connection between the first housing 82 and the second housing 83 inside the rubber ball 8 with the slide rail should be heat fusion to ensure that they do not separate during deformation.

[0050] In the above embodiments, another optional implementation includes a fixing plate 3, one end of which is rotatably connected to the end of the telescopic rod 6 away from the rubber ball 8, and the other end is connected to the fixing ring 4 by bolts.

[0051] Specifically, the fixing plate 3 should be a steel structure, rectangular in shape, with two bolt through holes at the bottom for connecting two adjacent fixing rings 4, and an extended top with one bolt through hole for fixing the telescopic rod 6. That is, the fixing plate 3 has three bolt through holes, ensuring that the spacing between two of these holes matches the fixing ring 4. Each fixing plate 3 can only connect one telescopic rod 6 and two fixing rings 4.

[0052] In the above embodiments, another optional implementation includes a fixing seat 11, which is fixedly connected to the rubber ball 8. Specifically, the fixing seat 11 is fixedly connected to the connecting body or the plane, serving to support the fixing seat 11.

[0053] Working principle: For some suspended pipes that are prone to vibration, a roll plate 21 is wrapped around the vibrating part of the suspended pipe 1 (the distance between the two ends of the roll plate 21 is adjusted by adjusting the distance between the two corresponding connecting rings 5 ​​to adapt to suspended pipes 1 of different diameters). Then, the fixing plate 3 is connected to the fixing ring 4 with bolts, and the fixing plate 3 is fixedly connected to one end of the telescopic rod 6. The other end of the telescopic rod 6 is connected to the arc plate 7, which is slidably installed on the slide rail 81 of the rubber ball 8. The magnetorheological fluid 9 is injected into the first housing 82. The circuit on the outside or inside of the rubber ball 8 is connected to the power supply. The magnetic field generated by the circuit changes the viscosity of the magnetorheological fluid 9. The telescopic rod 6 pushes the rubber ball 8 to deform. The force generated acts on the magnetorheological fluid 9 (because the viscosity of the magnetorheological fluid 9 changes after being energized), which hinders the vibration and reduces the amplitude frequency.

[0054] When the suspended pipe 1 vibrates, the rubber arc plate 10 inside the pipe wrapping cylinder 2 increases the first layer of damping of the pipe, and the full wrapping rubber reduces the vibration in all directions of the suspended pipe 1; the combination of multiple telescopic rods 6 and rubber balls 8 ensures that the shape of the pipe wrapping cylinder 2 does not change significantly, thereby increasing the second layer of damping control; the telescopic rods 6 squeeze the rubber balls 8 to increase the third layer of damping control; the viscosity is changed by the magnetorheological fluid 9, and the telescopic rods 6 will push the rubber balls 8 to deform. The force generated acts on the magnetorheological fluid 9 (because the viscosity of the magnetorheological fluid 9 is changed after being energized), which hinders the vibration and reduces the amplitude frequency to increase the fourth layer of damping.

[0055] The pipe wrapping cylinder 2 is fixed to other fixed surfaces by fixing rings 4 on both sides, and the rubber ball 8 is fixed to the fixing seat 11. The fixing seat 11 is then used to fix it to the external structure to increase the stability of the suspended pipe 1. This effectively solves the problems of difficulty in finding support points for vibration of the suspended pipe 1, difficulty in maintenance, and low efficiency.

[0056] 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.
