Description

Technical Field

[0001] The utility model relates to the technical field of submarine pipeline fixing, in particular to a pipeline limiting bracket. Background Art

[0002] As an important component of modern energy, offshore oil development and utilization are attracting increasing attention. Compared with terrestrial oil, offshore oil resources have advantages such as abundant reserves, high quality, and relatively easy extraction.

[0003] The extraction and transportation of offshore oil requires laying pipelines on the seabed to transport the extracted oil. Pipeline supports are used to secure these pipelines. Existing pipe supports typically only provide a simple securing function, but these supports are easily affected by ocean currents and can fail, rendering them ineffective in securing the pipelines. Utility Model Content

[0004] Aiming at the problem in the prior art that submarine pipeline supports are easily ineffective under the impact of ocean currents, the utility model provides a pipeline limiting support to improve the reliability of submarine pipeline fixation.

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A pipeline limit bracket includes a limit assembly, a plug-in assembly and a buffer assembly, the limit assembly has a limit portion for matching and sleeved on the outside of the pipeline body, the plug-in assembly is fixedly connected to the limit assembly, the plug-in assembly has a connector for inserting into the seabed, the buffer assembly includes a buffer plate and an elastic buffer structure, the buffer plate is arranged on both sides of the limit portion, and one end of the elastic buffer structure is connected to the buffer plate, and the other end of the elastic buffer structure is connected to the limit portion.

[0007] In the technical solution of the application, a buffer assembly acts as a buffer against seabed currents, preventing them from significantly impacting the pipeline limit bracket. When the pipeline limit bracket is subjected to radial currents, the currents act on the buffer plate, reducing the impact of the current on the pipeline limit bracket. The vibration generated by the buffer plate is absorbed and buffered by the elastic buffer structure, thereby preventing failure of the pipeline limit bracket, achieving better support and protection for the pipeline body, and improving the reliability of submarine pipeline fixation.

[0008] Furthermore, the buffer plate has a first buffer surface and a second buffer surface, the first buffer surface is arranged on the upper side of the second buffer surface, and the angle between the first buffer surface and the second buffer surface is an obtuse angle toward the limiting portion.

[0009] In the above technical solution, the buffer plate guides the ocean current in sequence through the second buffer surface arranged on the lower side and the first buffer surface on the upper side. The angle between the first buffer surface and the second buffer surface is an obtuse angle and faces the limiting part to reduce the impact of the ocean current on the pipeline limiting bracket.

[0010] Furthermore, the distance between the first buffer surface and the limiting portion is smaller than the distance between the second buffer surface and the limiting portion, the angle between the second buffer surface and the horizontal plane is an acute angle toward the limiting portion, and the angle between the first buffer surface and the horizontal plane is smaller than the angle between the second buffer surface and the horizontal plane.

[0011] In the above technical solution, the ocean current coming from the side first contacts the second buffer surface, and then is guided by the second buffer surface to the first buffer surface. The angle between the first buffer surface and the horizontal plane is smaller, which makes it easier to guide the ocean current to flow through the top of the first buffer surface and reduce the impact of the ocean current.

[0012] Furthermore, the elastic buffer structure includes a damper and a spring sleeved on the damper, and two ends of the spring are respectively connected to two ends of the damper.

[0013] In the above technical solution, the spring and the damper play a shock-absorbing and buffering role, which can reduce the impact of the ocean current.

[0014] Furthermore, the plug-in assembly further includes a connecting plate, the plug-in component is mounted on the connecting plate, and the connecting plate is fixedly connected to the bottom of the limiting portion.

[0015] In the above technical solution, the fixing plate is used to install the limiting assembly and the connector, and the connector fixes the entire pipeline limiting bracket to the seabed.

[0016] Furthermore, the connecting plate is provided with a first through hole for the connector to pass through and screw hole columns located on both sides of the first through hole, threaded holes are provided in the screw hole columns, and second connecting ears corresponding to the positions of the screw hole columns are provided on both sides of the top of the connector, and the second connecting ears are provided with a second through hole, the connector is arranged in the first through hole, and the second through hole and the threaded hole are connected by bolts.

[0017] In the above technical solution, the bolt passes through the second through hole of the second connecting bracket and is connected to the screw hole column, so that the connection between the connecting plate and the connector is firmly connected, and disassembly and assembly are facilitated.

[0018] Furthermore, the connector has a connecting end and a plugging end, the connecting end is located on the upper side of the connecting plate, the second connecting lugs are arranged on both sides of the connecting end, and the plugging end is located on the lower side of the connecting plate.

[0019] In the above technical solution, the connecting end of the connector is used to connect to the connecting plate, and the plugging end of the connector is used to be fixedly connected to the seabed.

[0020] Furthermore, the two connectors are both obliquely arranged on both sides of the bottom of the limiting component, and the lower ends of the two connectors are close to each other.

[0021] In the above technical solution, the stability of the connection between the plug-in assembly and the seabed can be improved by using the two plug-in components with their lower ends close to each other.

[0022] Furthermore, the limiting portion includes a first enclosed portion and a second enclosed portion, the first enclosed portion and the second enclosed portion are connected to form a third through hole matching the outer side of the pipe body, and the two ends of the first enclosed portion and the second enclosed portion are respectively detachably connected.

[0023] In the above technical solution, the first enclosing part and the second enclosing part are detachably connected, so as to facilitate assembly with the pipeline.

[0024] Furthermore, the first enclosed portion and the second enclosed portion each have a first connecting lug facing the connecting plate, and the first connecting lug is connected to the connecting plate.

[0025] In the above technical solution, the first connecting lug is used to facilitate connection with the connecting plate.

[0026] Technical effect of the present invention: In the present invention, the pipeline limit bracket includes a limit component, a plug-in component and a buffer component. The pipeline is limited by the limit component, and the limit component and the pipeline are connected and fixed on the seabed by the plug-in component. The buffer component includes a buffer plate and an elastic buffer structure. The buffer plate is arranged on both sides of the limit part, and can buffer the ocean current on the seabed through the buffer component, thereby preventing the ocean current from causing a large impact on the pipeline limit bracket. When the pipeline limit bracket is subjected to radial ocean current, the ocean current will act on the buffer plate, reducing the impact of the ocean current on the pipeline limit bracket. The vibration generated by the buffer plate is absorbed and buffered by the elastic buffer structure, thereby avoiding the failure of the pipeline limit bracket, achieving a better support effect and protection effect on the pipeline body, and improving the reliability of the submarine pipeline fixation.

[0035] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0036] Example 1

[0037] like Figures 1 to 4 The figure shows the first embodiment of the pipeline limit bracket of the present invention, which includes a limit component 1, a plug-in component 2 and a buffer component 3. The limit component 1 has a limit portion 11 for matching and sleeved on the outside of the pipeline body 4. The plug-in component 2 is fixedly connected to the limit component 1. The plug-in component 2 has a connector 22 for inserting into the seabed. The buffer component 3 includes a buffer plate 31 and an elastic buffer structure 32. The buffer plate 31 is arranged on both sides of the limit portion 11, and one end of the elastic buffer structure 32 is connected to the buffer plate 31, and the other end of the elastic buffer structure 32 is connected to the limit portion 11.

[0038] In the embodiment, the pipe limit bracket is fixed to the seabed via the plug assembly 2, and the pipe body 4 is fixed in position via the limit assembly 1 connected to the plug assembly 2. The buffer assembly 3 acts as a buffer against the ocean currents on the seabed, preventing the ocean currents from causing a large impact on the pipe limit bracket. When the pipe limit bracket is subjected to radial ocean currents, the ocean currents will act on the buffer plate 31, reducing the impact of the ocean current on the pipe limit bracket. When the ocean current impacts, the vibration generated by the buffer plate 31 is absorbed and buffered by the elastic buffer structure 32, thereby preventing the pipe limit bracket from failing, achieving better support and protection for the pipe body 4, and improving the reliability of the submarine pipeline fixation.

[0039] like Figure 1 As shown, in this embodiment, the buffer plate 31 has a first buffer surface 311 and a second buffer surface 312. The first buffer surface 311 is located above the second buffer surface 312, and the angle between the first and second buffer surfaces 311 and 312 is an obtuse angle, oriented toward the stopper 11. The buffer plate 31 sequentially guides ocean currents through the second buffer surface 312 on the lower side and the first buffer surface 311 on the upper side. The ocean currents are guided by the buffer plate 31 to flow diagonally upward, thereby reducing the impact of the ocean currents on the pipeline stopper bracket. The angle between the first and second buffer surfaces 311 and 312 is an obtuse angle, oriented toward the stopper 11. Compared to an acute angle, an obtuse angle is more conducive to guiding the ocean currents along the two buffer surfaces of the buffer plate 31, thereby reducing the impact of the ocean currents. In this embodiment, the width of the buffer plate 31 along the pipeline axis is preferably not less than the width of the stopper 11 along the pipeline axis. The buffer plate 31 can cover the stopper 11, reducing the impact of the ocean currents on the stopper 11 and ensuring the stability of the pipeline stopper bracket.

[0040] like Figure 1As shown, in this embodiment, the distance between the first buffer surface 311 and the limiting portion 11 is smaller than the distance between the second buffer surface 312 and the limiting portion 11, the angle between the second buffer surface 312 and the horizontal plane is an acute angle toward the limiting portion 11, and the angle between the first buffer surface 311 and the horizontal plane is smaller than the angle between the second buffer surface 312 and the horizontal plane. The ocean current coming from the side first contacts the second buffer surface 312, and then, under the guidance of the second buffer surface 312, reaches the first buffer surface 311. The angle between the first buffer surface 311 and the horizontal plane is smaller, which facilitates guiding the ocean current to flow through the top of the first buffer surface 311 and reduce the impact of the ocean current. The transition between the first buffer surface 311 and the second buffer surface 312 is preferably rounded to reduce the impact of the ocean current.

[0041] refer to Figure 1 and Figure 2 In this embodiment, the plug assembly 2 includes a connecting plate 21 and a plug connector 22 mounted on the connecting plate 21. The connecting plate 21 is fixedly connected to the bottom of the limit assembly 1, and the plug connector 22 is mounted on the connecting plate 21. The fixing plate is used to mount the limit assembly 1 and the plug connector 22, which is used to connect and secure the pipeline limit bracket to the seabed. The plug connector 22 can be plugged and fixed to the seabed. The connecting plate 21 and the plug connector 22 can be threaded together, and the connecting plate 21 can also be threaded to the bottom of the limit assembly 1.

[0042] refer to Figure 1 and Figure 2 The two connectors 22 are arranged at an angle on either side of the bottom of the stopper assembly 1, with their lower ends close to each other. Preferably, the two connectors 22 are symmetrically arranged on either side of the bottom of the stopper assembly 1 to improve the stability of the connection with the seabed. The two connectors 22 are arranged at a certain angle, with their bottoms close to each other and tilted, making the pipeline stopper bracket more stable when subjected to lateral ocean currents.

[0043] refer to Figure 1 The elastic buffer structure 32 includes a damper 321 and a spring 322 sleeved on the damper 321. The two ends of the spring 322 are respectively connected to the two ends of the damper 321. One end of the elastic buffer structure 32 is connected to the buffer plate 31, and the other end is connected to the limiter 11. The spring 322 and the damper 321 play a shock-absorbing and buffering role, which can reduce the impact of ocean currents.

The buffer plate 31 is arranged on both sides of the limit portion 11, and one end of the elastic buffer structure 32 is connected to the buffer plate 31, and the other end of the elastic buffer structure 32 is connected to the limit portion 11.

The plug-in connector 22 is disposed in the first through-hole 211 and is connected to the second connecting lugs 223 and the screw posts 212 via bolts. The bolts pass through the second through-holes 224 of the second connecting lugs 223 and connect to the screw posts 212, thereby providing a secure connection between the connecting plate 21 and the plug-in connector 22 and facilitating disassembly and assembly.

[0047] refer to Figure 1 and Figure 2 The connector 22 has a connecting end 221 and a plug end 222, with second connecting lugs 223 on either side of the connecting end 221. The connecting end 221 and the second connecting lugs 223 are located above the connecting plate 21, while the plug end 222 is located below the connecting plate 21. The connecting end 221 of the connector 22 is used to connect to the connecting plate 21, while the plug end 222 of the connector 22 is used to securely connect to the seabed. The second connecting lugs 223 are located above the screw hole column 212 of the connecting plate 21, facilitating connection to the screw hole column 212 from above.
