Description

Technical Field

[0001] This utility model relates to the field of marine engineering technology, and in particular to a pipeline fixing device for marine engineering. Background Technology

[0002] Patent publication number CN221974501U discloses a marine pipeline support frame, comprising: a base, a fixing device on the base, a support block fixedly connected to the base, an adjustment mechanism on the support block, a pipe sleeve fixedly connected to the adjustment mechanism, two protruding plates fixedly connected to the upper surface of the base, and force-amplifying plates fixedly connected to the front and rear surfaces of the base. The semi-circular protruding plates guide the water flow at the seabed, changing its direction and reducing the impact force on the pipe sleeve. The triangular force-amplifying plates, when impacted by the water flow, not only change its direction but also apply force to the fixing rod, making it more securely fixed. The fixing device facilitates fixing the entire frame to the seabed, and the adjustment structure allows for adjustment of the pipe sleeve's height, increasing overall practicality.

[0003] However, the patent uses multiple bolts to connect and fix the upper and lower pipe sleeves. During installation, multiple bolts are required, which reduces the efficiency of laying the marine pipeline on the support frame. Utility Model Content

[0026] By hinged together with the upper sleeve 6 and the lower sleeve 7 and connected and fixed by fasteners, the installation and fixing efficiency between the upper sleeve 6 and the lower sleeve 7 is improved, avoiding the cumbersome installation process of the traditional multi-bolt fixing method, thereby improving the installation efficiency of marine pipelines and facilitating the disassembly and assembly of pipelines and support frames.

[0027] Working principle: During use, the support frame is placed on the sea surface, then the water inlet valve 17 is opened, and the support frame is pressed down, causing it to sink to the seabed. Simultaneously, seawater enters the water cavity 16 of the float 1 through the water inlet valve 17, increasing the counterweight of the support frame and causing it to sink rapidly to the seabed. After the float 1 reaches the seabed: the drilling rig 13 drives the anchor rod 14 to rotate; the electric push rod 11 drives the support plate 12 to descend, and the support plate 12 drives the drilling rig 13 and the rotating anchor rod 14 to descend, causing the anchor rod 14 to drill into the seabed soil layer, fixing the float 1 in place. On the seabed, by rotating handwheel 9, the handwheel 9 drives worm gear 22 to rotate via shaft 10. Worm gear 22 drives turbine gear 21 to rotate. When turbine gear 21 rotates, it drives screw 8 to rise and fall. Screw 8 drives lower sleeve 7 and upper sleeve 6 to rise and fall, adjusting the installation height of the pipe. Then, rotating block 34 drives connecting rod 32 to rotate. Connecting rod 32 drives stud 39 to rotate, causing stud 39 to unscrew from thread groove 38. At the same time, connecting rod 32 drives sleeve 31 to move appropriately, and second spring 36 moves appropriately. Compression occurs when the stud 39 exits the threaded groove 38. The external pull block 34, via the connecting rod 32, moves the sleeve 31, causing the second spring 36 to compress completely. The sleeve 31 then exits the insert block 28, and the upper sleeve 6 flips upwards to open. When the insert block 28 exits the slot 29, the compressed first spring 27 resets, causing the insert block 28 to move. The pipe is then placed inside the lower sleeve 7, and the upper sleeve 6 is closed. During closure, the insert block 28, guided by its bottom arc-shaped surface, moves... When inserted into slot 29, the insert 28 moves while the first spring 27 is compressed, causing the insert 28 to be inserted into slot 29 and the positioning hole 30 on the insert 28 to align with the through hole 33. Then, the screw block 34 is released, and the second spring 36, which is in a compressed state, is appropriately reset, so that the sleeve 31 is fitted into the positioning hole 30 in the insert 28, while the stud 39 abuts against the entrance end of the threaded groove 38. Then, the screw block 34 is rotated, so that the stud 39 is screwed into the threaded groove 38, and the sleeve 31 moves for the last time, causing the second spring 36 to finally reset.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
