Description

Technical Field

[0001] The utility model relates to the technical field of trench landfilling, in particular to a marine pipeline trench siltation promoting device. Background Art

[0002] Submarine pipelines are pipelines that continuously transport large amounts of oil and gas on the seabed through closed pipes. They are currently the fastest, safest, most economical and reliable way to transport offshore oil and gas. They are widely used in today's marine engineering and have become an important part of offshore oil and gas development. After the pipeline is laid, seabed soil backfill is required to prevent sand from being washed away by sea currents, ensure the stability of the pipeline, and increase the service life of the pipeline.

[0003] After searching, the Chinese patent with the publication number CN218543393U discloses a marine pipeline trench siltation promoting device, including a support frame, an adjustment frame, and a guide wheel assembly. The top surface of the support frame is slidably connected with two slides; a width adjustment assembly is installed between the support frame and the two slides; the bottom surfaces of the two slides are fixed with supports, blades, and soil covering assemblies; the adjustment frame includes two horizontal plates and two vertical plates; the two horizontal plates and the two vertical plates are hinged end to end and enclosed to form a frame; one of the horizontal plates is hinged to the support frame through a hinge assembly; the guide wheel assembly is installed at the bottom of the two vertical plates; wherein the two blades are located between the guide wheel assembly and the soil covering assembly, and the blades and the soil covering assembly are both located between the two supports. The utility model can guide the running direction when the submarine pipeline trench is buried, flexibly turn, improve the burial effect and efficiency, and adapt to trenches of different widths.

[0004] However, in the above technical solution, the blade is adjusted by a width adjustment assembly to adapt to grooves of different widths. When the groove widths are different, the diameters of the pipes prevented therein are also different, resulting in the guide wheel spacing being unable to be adjusted when the guide wheel contacts a pipe with a larger diameter. When encountering a pipe with a smaller or larger diameter, the length of the first rotating shaft cannot be adjusted, making it impossible for the guide wheel to contact the pipe or the guide wheel lifts the support frame, affecting normal burying and guiding work.

[0020] Embodiment 1

[0021] like Figure 1-Figure 4 As shown, the utility model proposes a marine pipeline groove siltation promoting device, including a support frame 1, a sliding plate 2, a lifting ear 3, a width adjustment component and a burying component. A plurality of equidistant and evenly distributed sliding plates 2 are arranged below the support frame 1. The support frame 1 is connected to the ship through the lifting ear 3 connected in front thereof. The power generated by the movement of the ship drives the support frame 1 to move on the seabed through the sliding plate 2. When the support frame 1 moves, the width adjustment component below it will slide along the groove. The width adjustment component maintains close contact with the groove so that it can guide the movement of the support frame 1 to keep it consistent with the direction of the groove. When the support frame 1 moves, the burying component always maintains contact with the seabed soil, and the soil is lifted up by the burying component to bury the pipeline in the groove.

[0022] In an optional embodiment, the cross section of the support frame 1 is an I-shaped one when viewed from above, and the cross bars at both ends of the support frame 1 are connected to symmetrically arranged support rods 20, which are used to connect the sliding plate 2. The I-shaped support frame 1 makes the force more uniform, and the multiple support rods 20 prevent the support frame 1 from tilting forward or backward, so as to prevent the burying component from entering the soil too deep or too shallow to play a burying role.

[0023] Embodiment 2

[0024] like Figure 2-Figure 4As shown, a marine pipeline groove siltation promoting device proposed by the utility model, compared with the first embodiment, in this embodiment, the width adjustment component includes a fixed plate 4, a guide groove 5, a guide rod 6, a connecting rod 7, a guide plate 8 and an elastic member 9, the guide groove 5 is symmetrically arranged on both sides of the bottom of the fixed plate 4, the guide groove 5 is connected with the guide rods 6 stacked up and down in parallel, the connecting rod 7 with a plurality of through holes is slidably connected to the guide rod 6, the guide plates 8 are detachably connected on both sides of the connecting rod 7, and the bottom of the connecting rod 7 is used to connect the guide plate 8 in contact with the seabed groove. When the support frame 1 is driven by the ship to move along the seabed groove through the lifting ear 3, the guide plate 8 will contact the two side walls of the groove. When the groove is too wide or too narrow, the elastic member 9 will push the connecting rod 7 to move along the axis of the guide rod 6 in the guide groove 5, so that the guide plate 8 keeps in contact with the side wall of the groove, thereby guiding and limiting the movement of the support frame 1, and can drive the buried component to move through the movement of the connecting rod 7, so as to avoid the problem that the buried component cannot contact the ground due to the excessive width of the groove.

[0025] In an optional embodiment, the elastic member 9 includes a U-shaped plate 14, a sliding block 15, a spring 17 and a fixing bolt 18. The two ends of the guide groove 5 are provided with sliding grooves 16, and the sliding grooves 16 are used for sliding connection with the sliding blocks 15. A plurality of evenly distributed springs 17 are provided on both sides of the connecting rod 7. The two ends of the spring 17 are connected with U-shaped plates 14. The U-shaped plates 14 near the two ends of the guide groove 5 are used to connect with the sliding blocks 15. The fixing bolts 18 pass through the U-shaped plate 14 with the sliding blocks 15 to connect the U-shaped plate 14 with the guide groove 5. When one side of the connecting rod 7 is subjected to external force and the other side loses external force, the spring 17 will push the U-shaped plate 14 to drive the connecting rod 7 to move to the side that wants to lose the external force, so that the connecting rod 7 drives the guide plate 8 to be close to the inner wall of the seabed groove, and the fixing bolts 18 make the U-shaped plate 14 able to be disassembled and replaced, so as to avoid seawater corrosion causing the spring 17 to be damaged and unable to play the role of width adjustment.

[0029] The blade 11 is connected to the other end of the fixed rod 10. When the connecting rod 7 is driven by the support frame 1 to move along the groove, the fixed rod 10 and the blade 11 will also move synchronously.
