[0002] Riser pipes are essential drilling equipment for offshore drilling. Currently, conventional methods for improving the riser's structural resistance to wind, waves, currents, and ice are to use larger riser sizes or increase the riser's wall thickness to improve its overall mechanical properties. However, this type of structure increases the steel content of the riser, significantly increasing offshore operating costs.

[0003] An existing patent (Announcement No.: CN202090847U) discloses a reinforced riser assembly structure that can reduce the size of the riser assembly while ensuring safe drilling operations. While maintaining the same mechanical properties as a larger riser assembly, it significantly reduces the amount of steel used, saving significant engineering costs while not impacting the drilling schedule. During the implementation of this solution, the following problems were discovered in the prior art that have not been adequately addressed:

[0004] During use, the device realizes a combined structure through a snap-fit ​​structure, but the watertight duct is often used in the ocean, where the direction of water flow often changes, and there are a large number of waves impacting the watertight duct, which can easily cause changes in the tightness of the connection, thereby deteriorating the sealing performance.

[0031] Working principle: When in use, first, engage the first protective block 2 and the second protective block 3 with each other, then install the threaded block 8 and the nut 11 in sequence to complete the fixing and installation of the threaded block 8. At this time, the sliding block 9 and the bottom of the threaded block 8 are engaged with the inside of the sliding groove 10. Then, rotate the second protective block 3 so that the sliding block 9 slides to the bottom of the sliding groove 10, completing the preliminary fixing work;

[0032] As mentioned above, after the second protective block 3 is fixed and installed, the limiting rod 4 enters the anti-slip groove 6. Once the waves hit the first protective block 2, the limiting rod 4 and the anti-slip groove 6 slide, squeezing the first spring 5. The first spring 5 performs preliminary buffering.
