Description

Technical Field

[0001] This utility model relates to the field of submarine pipelines, and in particular to a stabilizing device for submarine pipeline construction that resists the impact of undercurrents. Background Technology

[0002] Submarine pipelines are tubular engineering facilities laid on the seabed, including coastal and shallow waters. They are mainly used to transport fluid media such as oil, gas, water, and mud, and are an indispensable key infrastructure in marine resource development, especially oil and gas extraction and marine engineering construction.

[0003] In submarine pipeline construction projects, the impact of undercurrents is one of the core factors threatening pipeline stability. However, current submarine pipeline supports have poor resistance to undercurrent impacts. When the undercurrent velocity exceeds the design value, stress concentration is likely to occur at the pipeline connection points, which can easily lead to displacement and leakage of the pipeline connection points, affecting transportation safety. To address this issue, we propose an undercurrent impact-resistant stabilization device for submarine pipeline construction. Utility Model Content

[0004] The purpose of this invention is to provide a stabilizing device for submarine pipeline construction that resists the impact of undercurrents, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A stabilizing device for subsea pipeline installation that resists the impact of undercurrents includes a stabilizing base plate. Two fixing seats are fixedly connected to the upper surface of the stabilizing base plate. A subsea pipeline is mounted on the upper surface of both fixing seats. An arc-shaped fixing plate is positioned above each of the two fixing seats, and both arc-shaped fixing plates are located above the subsea pipeline. Two buffer plates are positioned above the stabilizing base plate. A fixing plate is fixedly connected to the bottom surface of the stabilizing base plate. Two sets of springs are fixedly installed on the outer surface of the fixing plate. A sliding plate is fixedly connected to one end of each set of springs. The top ends of the two sets of sliding plates are fixedly connected to the outer surfaces of the two buffer plates. Two fixing members are fixedly connected to the bottom surface of the stabilizing base plate, and each fixing member has a fixing opening on its bottom surface.

[0007] In a further embodiment, the upper surface of the stable base plate is provided with two sets of sliding holes, the outer surfaces of the two sets of sliding plates are slidably connected to the inner walls of the two sets of sliding holes, and buffer pads are fixedly connected to the inner walls of the two sets of sliding holes. The side of the two sets of buffer pads that are close to each other are in contact with the side of the two sets of sliding plates that are far apart from each other.

[0008] In a further embodiment, two fixing holes are provided on the outer surfaces of the two arc-shaped fixing plates, and fixing screws are provided above the two fixing holes. Two threaded grooves are provided on the upper surfaces of the two fixing seats, and the outer surface of the fixing screws is adapted to the inner wall of the threaded grooves.

[0009] In a further embodiment, two of the fixed seats and two of the arc-shaped fixed pressure plates are fixedly connected to arc-shaped fixing pads on their adjacent sides, and anti-slip protrusions are provided on the adjacent sides of the two sets of arc-shaped fixing pads.

[0010] In a further embodiment, two anchor plates are fixedly connected to one side of the two sets of fasteners that are close to each other, and two anchor holes are opened on the upper surface of each of the two anchor plates.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention, through the setting of a fixed base and an arc-shaped fixed pressure plate, and the cooperation of fixed screws, fixed holes and threaded grooves, can firmly fix the subsea pipe body, avoiding displacement of the subsea pipe body caused by the impact of undercurrents. The connection stability with the seabed is enhanced by the fixing parts, fixing ports, anchor plates and anchor holes, preventing the overall sinking of the device.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 In this utility model, an anti-current impact stabilization device for subsea pipeline construction includes a stabilizing base plate 1. Two fixing seats 2 are fixedly connected to the upper surface of the stabilizing base plate 1. A subsea pipe body 3 is mounted on the upper surface of the two fixing seats 2. An arc-shaped fixing pressure plate 4 is located above each of the two fixing seats 2, both positioned above the subsea pipe body 3. Two buffer plates 9 are located above the stabilizing base plate 1. A fixing plate 5 is fixedly connected to the bottom surface of the stabilizing base plate 1. Two sets of springs 6 are fixedly installed on the outer surface of the fixing plate 5. Sliding plates 7 are fixedly connected to the ends of the two sets of springs 6 that are mutually perpendicular. The top ends of the two sets of sliding plates 7 are respectively connected to the outer surfaces of the two buffer plates 9. The bottom surface of the stable base plate 1 is fixedly connected to two fasteners 15. The bottom surface of each fastener 15 is provided with a fixing port 16. The two sets of fasteners 15 are fixedly connected to two anchor plates 17 on their adjacent sides. The upper surface of each anchor plate 17 is provided with two anchor holes 18. Through the setting of the fixing seat 2 and the arc-shaped fixing pressure plate 4, and with the cooperation of fixing screws 12, fixing holes 11 and threaded grooves 10, the seabed pipe 3 can be firmly fixed, avoiding displacement of the seabed pipe 3 caused by the impact of undercurrents. The connection stability with the seabed is enhanced by the fasteners 15, fixing ports 16, anchor plates 17 and anchor holes 18, preventing the overall sinking of the device.

[0020] In a further embodiment, the upper surface of the stable base plate 1 is provided with two sets of sliding holes 8. The outer surfaces of the two sets of sliding plates 7 are slidably connected to the inner walls of the two sets of sliding holes 8 respectively. The inner walls of the two sets of sliding holes 8 are fixedly connected with buffer pads 14. The side of the two sets of buffer pads 14 that are close to each other are in contact with the side of the two sets of sliding plates 7 that are far from each other. Through the buffer assembly composed of buffer plate 9, sliding plate 7, spring 6 and sliding hole 8, when the current impacts the buffer plate 9, the sliding plate 7 slides along the sliding hole 8 and squeezes the spring 6 on the fixed plate 5. The spring 6 deforms and absorbs the impact force, while the buffer pad 14 in the sliding hole 8 can buffer the reaction force when the sliding plate 7 resets. Thus, through buffering, the transmission of impact force to the seabed pipe 3 is reduced, and the risk of stress concentration is reduced.

[0021] In a further embodiment, two fixing holes 11 are provided on the outer surface of each of the two arc-shaped fixing plates 4, and fixing screws 12 are provided above each of the two fixing holes 11. Two threaded grooves 10 are provided on the upper surface of each of the two fixing seats 2, and the outer surface of the fixing screws 12 is adapted to the inner wall of the threaded grooves 10. Arc-shaped fixing pads 13 are fixedly connected to the side of each of the two fixing seats 2 and the two arc-shaped fixing plates 4 that are close to each other. Anti-slip protrusions are provided on the side of each of the two sets of arc-shaped fixing pads 13 that are close to each other. Through the fixing plate 5, the fixing member 15 and the anchor plate 17, it can be connected and fixed to the seabed. In addition, the anchor hole 18 of the anchor plate 17 can be used to insert anchors to enhance the grip. The two work together to improve the overall connection strength between the device and the seabed.

[0022] The working principle of this utility model is as follows: First, the fixed seat 2 and the arc-shaped fixed pressure plate 4 pass through the fixed hole 11 through the fixed screw 12, and then are screwed into the inside of the threaded groove 10, which can fix the seabed pipe 3 and prevent the seabed pipe 3 from shifting. Then, the fixing member 15 is fixed to the seabed through the fixing port 16, the anchor plate 17 and the anchor hole 18. When the undercurrent impacts, the buffer plate 9 is first subjected to force, pushing the sliding plate 7 to slide along the sliding hole 8, squeezing the spring 6 on the fixed plate 5, and using the deformation of the spring 6 to absorb the impact force and reduce the stress concentration of the seabed pipe 3. In addition, the buffer pad 14 in the sliding hole 8 further buffers the impact force when the sliding plate 7 is reset, and then the overall structure disperses the impact force of the undercurrent.
