Description

Technical Field

[0001] This invention relates to the field of sand throwing equipment technology, and in particular to a tipping bucket sand throwing device for marine engineering. Background Technology

[0002] The seabed environment in the Chengdao waters is complex. Parts of the seabed are affected by ocean dynamics and changes in seabed topography, causing extensive erosion, especially near platforms where the presence of platforms and other structures exacerbates the erosion. These factors have resulted in the exposure and suspension of some subsea pipelines.

[0003] Currently, the industry commonly uses sand-filling operations to address exposed and suspended subsea pipelines. This involves dumping sand and gravel into the exposed or suspended areas of the pipeline to fill depressions caused by seabed erosion, providing stable support for the pipeline, covering the exposed outer wall, and thus eliminating safety hazards. However, in actual offshore construction, previous offshore sand-filling operations mainly relied on ordinary barges carrying sand and gravel, using manual dumping methods. This method is constrained by the complex offshore construction environment of the Chengdao sea area, resulting in many drawbacks, making sand-filling construction difficult and yielding poor results.

[0051] The ejection mechanism 2 consists of a plurality of ejection plates 201 that slide vertically on the first slide plate 18, a second motor 202 that is mounted on the fixed guide rail 3, a first lead screw 203 that is rotatably mounted on the fixed guide rail 3, the output shaft of the second motor 202 that is fixedly connected to one end of the first lead screw 203, and the first lead screw 203 that is threadedly connected to the first slide plate 18.

The tipping sand box 4 is in the tipping operation state as follows. Figure 10As shown, the output shaft of the fifth motor 15 drives the fourth gear 14 to rotate. The fourth gear 14 drives the fifth gear 17 to rotate through meshing with the fifth gear 17. The fifth gear 17 drives the tipping sand box 4 on the fixed plate 6 to rotate, adjusting the position of the tipping sand box 4 in the circumferential direction.

[0053] Multiple guide sand-throwing boxes 13 connected end to end are fixed on the support plate 12. The output end of the fourth electric cylinder 9 drives the bottom bracket 11, the support plate 12 and the guide sand-throwing boxes 13 to move, adjusting the position of the guide sand-throwing boxes 13 in the tilt direction. The output shaft of the sixth motor 21 drives the sixth gear 22 to rotate. The sixth gear 22 drives the gear ring 20 to rotate through meshing with the gear ring 20. The gear ring 20 drives the connecting ring 8 to rotate on the sand box base 7. The connecting ring 8 drives the multiple fixed guide sand-throwing boxes 13 connected end to end to rotate through the L-shaped connecting plate 10, the bottom bracket 11 and the support plate 12, adjusting the position of the guide sand-throwing boxes 13 in the circumferential direction. The output end of the fifth electric cylinder 23 drives the support plate 12 to slide on the bottom bracket 11, moving the inlet end of the guide sand-throwing box 13 located at the top to the outlet end aligned with the tipping sand box 4.

[0054] The method for fixing multiple guide sand-throwing boxes 13 connected end to end is as follows: the multiple guide sand-throwing boxes 13 connected end to end are connected by bolts 33 respectively. The output shafts of the sixth electric cylinders 29 located on both sides of the guide sand-throwing box 13 drive multiple third plugs 34 on the third connecting plate 30 to plug into the third plug hole 37 of the guide sand-throwing box 13 located at the top. The guide sand-throwing box 13 located at the top is fixedly connected to the support plate 12. The output end of the seventh motor 27 drives the second lead screw 28 to rotate. The second slide plate 32 slides on the second slide groove 26 of the second lead screw 28 and the slide hole 24. The second protrusions 35 at the top and bottom of the second slide plate 32 slide in the second slide groove 26 respectively. The second slide plate 32 slides to the position where the guide sand-throwing box 13 needs to be fixed. The output end of the seventh electric cylinder 31 drives the fourth connecting plate 39 to slide in the second slide plate 32. The fourth connecting plate 39 drives multiple fourth plugs 36 to move to engage with the third plug hole 37 of the guide sand-throwing box 13.

[0055] During the sand-throwing operation, the output shafts of the first electric cylinders 104 on both sides drive the positioning plates 105 to move. The positioning plates 105 on both sides separate from the internal baffles 101. The output end of the first motor 106 drives the first gear 107 to rotate. The first gear 107 drives the second gear 108 to rotate through meshing transmission. The second gear 108 drives the internal baffles 101 to open through the first rotating shaft 103. At the same time, the second electric cylinders 110 on both sides drive the first connecting plate 111 to move. The first connecting plate 111 drives multiple first plugs 112 to move. The multiple first plugs 112 separate from the first plug holes 113 of the side baffles 102. The second drive assembly drives the second rotating shaft 109 to rotate. The second rotating shaft 109 drives the side baffles 102 to rotate, opening the internal baffles 101 and side baffles 102 inside the tipping sand box 4, adjusting the outflow speed of the sandbags in the tipping sand box 4, and effectively solving the problem of all sandbags being thrown into the sea at once.

[0056] In a humid marine environment, sandbags are prone to sticking together on their surface. Furthermore, due to mutual compression and friction within the tipping sand box 4, they easily adhere to the walls of the box, preventing smooth discharge. The output shaft of the fourth motor 210 drives multiple second connectors 208 to slide horizontally via the second connecting plate 209. The second connectors 208 separate from the second insertion holes 207 of the ejector plate 201. The output shaft of the third motor 206 drives the third gear 205 to rotate. The third gear 205, through meshing with the rack 204, drives the rack 204 to slide vertically on the first sliding plate 18. The output shaft of the second motor 202 drives the first lead screw 203 to rotate. The first sliding plate 18 slides horizontally within the first lead screw 203 and the first sliding groove 19, pushing the sandbags out of the tipping sand box 4. The sandbags then enter multiple end-to-end connected guide sand-throwing boxes 13, which throw the sandbags into the seabed.
