Description

Technical Field

[0001] This utility model belongs to the field of offshore platform equipment, specifically relating to a support leg for an offshore chain stop device with an adaptive structure. Background Technology

[0002] A floating offshore platform is a structure used for offshore oil and gas extraction, wind power generation, or other marine engineering activities. It can float on the water surface and operate relatively stably. Compared with traditional fixed platforms, floating offshore platforms can operate in deeper waters, expanding the scope of oil and gas extraction.

[0003] However, floating offshore platforms face higher operational risks under storm, strong wave, and extreme weather conditions, which may lead to safety hazards. In some cases, floating platforms may drift or become unstable.

[0004] When marine chain stop devices are installed on floating offshore platforms, they are affected by external forces such as waves, wind, and currents, causing the floating offshore platform to sway and move, resulting in poor overall stability of the floating offshore platform. At the same time, it increases the stress on the marine chain stop device and the floating offshore platform itself. In extreme weather or sudden events (such as wave impact, collision, etc.), external impact forces affect the floating offshore platform and marine chain stop device, increasing the risk of failure and damage.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0022] Please see Figures 1 to 3 The embodiments of this utility model include:

[0023] A support leg for a marine chain stop device with an adaptive structure includes a mounting base and a support plate 4. The support plate 4 is connected to the bottom of the mounting base, and the support plate 4 and the mounting base are connected by an adaptive structure. The adaptive structure can overcome the impact of harsh marine environments on the marine chain stop device, improve the stability of the floating offshore platform, increase the service life of the marine chain stop device, and reduce the risk of failure and damage.

[0024] The adaptive structure includes a telescopic structure for maintaining the stability of the marine chain stop device and a protective structure for ensuring the normal operation of the telescopic structure. The telescopic structure is disposed between the mounting base and the support plate 4, and the protective structure is mounted on the mounting base.

[0025] The mounting base consists of a leveling bracket 1, a hanging plate 2, and two side plates 3. The leveling bracket 1, the hanging plate 2, and the two side plates 3 form an installation space. A fixing plate 5 is installed on the rear side of each of the two side plates 3. The support leg is installed on the marine chain stop device through the fixing plate 5.

[0026] The leveling bracket 1 has a sliding hole 16 at its center, and a guide sleeve 11 is installed on the upper surface of the sliding hole 16. The guide sleeve 11 is used to ensure the stability of the sliding cylinder 7 when it slides up and down.

[0027] The guide sleeve 11 has a first limiting ring 13 on the inner wall of the opening, and a limiting washer 10 is installed on the lower surface of the sliding hole 16. The first limiting ring 13, the sliding hole 16, the guide sleeve 11 and the limiting washer 10 form a mounting groove. A bushing 12 is installed in the mounting groove. The bushing 12 is used to reduce the friction between the sliding cylinder 7 and the guide sleeve 11, reduce wear, and thus extend the service life of the sliding cylinder 7 and the guide sleeve 11. At the same time, it can provide a stable guiding effect to ensure that the sliding cylinder 7 maintains the correct trajectory during movement and avoids deviation or unnecessary vibration.

[0028] The telescopic structure includes a fixed cylinder 6 and a sliding cylinder 7. The sliding cylinder 7 is sleeved on the fixed cylinder 6. The fixed cylinder 6 is bolted to the groove at the bottom of the hanging plate 2. A sliding rod 8 with a piston block 9 is placed in the inner cavity 23 of the fixed cylinder 6. A second limiting ring 14 is provided at the opening of the bottom inner cavity 23 of the fixed cylinder 6. The sliding rod 8 moves up and down in the inner cavity 23. Compressed air is introduced through the connecting nozzle 22, which pushes the piston block 9 to move downward, thereby increasing the distance between the support plate 4 and the adjusting bracket, thus raising the height. It adopts a one-way air intake, and compressed air can only be introduced at one end. After the piston block 9 moves in one direction, it returns to its original position by its own gravity.

[0029] The sliding cylinder 7 is bolted to the bottom of the sliding rod 8 via a connecting block on the inner bottom surface. A third limiting ring 15 is provided on the outer wall of the sliding cylinder 7 near the bottom surface. The third limiting ring 15 cooperates with the limiting washer 10. The bottom of the sliding cylinder 7 is connected to the support plate 4. The third limiting ring 15 is used to prevent the top of the sliding rod 8 from colliding with the inner cavity 23 when the sliding rod 8 returns to its original position, thereby causing damage.

[0030] A connecting nozzle 22 is provided near the top of the outer wall of the fixed cylinder 6. The connecting nozzle 22 passes through the fixed cylinder 6 and communicates with the inner cavity 23. The connecting nozzle 22 is connected to an external air compressor. The external air compressor injects compressed air into the space between the top of the piston block 9 and the top of the inner cavity 23 through the connecting nozzle 22, thereby raising the support plate 4. Then, under its own weight, it can return to its original position. This can improve the stability of the floating offshore platform in harsh environments, increase the service life of the offshore chain stop device, and reduce the risk of failure and damage.

[0031] The protective structure includes two flexible hose clamps 20 and a telescopic flexible hose 21. The telescopic flexible hose 21 is sleeved on the outer wall of the sliding cylinder 7. The upper and lower ends of the telescopic flexible hose 21 are connected to the outer wall of the upper cover of the sliding cylinder 7 and the outer wall of the guide sleeve 11 respectively through the two flexible hose clamps 20. The telescopic flexible hose 21 is used to protect the sliding cylinder 7 and the guide sleeve 11, prevent dust and debris from entering, and increase its service life.

[0032] A clearance plate 17 is provided between the leveling bracket 1 and the support plate 4. The clearance plate 17 is fixedly connected to the bottom of the leveling bracket 1. A first clearance hole 18 is provided between the clearance plates 17. The first clearance hole 18 is used to allow the bolts that fix the limiting coil to make room, so as to prevent the top of the support plate 4 from colliding with the bolts and causing damage.

[0033] The bottom of the support plate 4 is fitted with a pad, and the top of the support plate 4 is provided with a second clearance hole 19. The second clearance hole 19 is used to allow the bolts that fix the bottom of the sliding cylinder 7 and the sliding rod 8 to make room, so that the top of the support plate 4 is tightly connected to the bottom of the sliding cylinder 7.

[0034] Unlike existing technologies, this utility model provides a support leg for a marine chain stop device with an adaptive structure. This support leg has an adaptive structure that can overcome the impact of harsh marine environments on the marine chain stop device, improve the stability of floating offshore platforms, increase the service life of the marine chain stop device, and reduce the risk of failure and damage.

[0035] By absorbing and dispersing dynamic loads, the stress transmitted to the offshore chain stop device and the floating offshore platform body is reduced, thereby reducing fatigue damage to the offshore chain stop device and improving its durability and service life.

[0036] By adjusting the relative movement between the floating offshore platform and the chain stop device, the swaying and tilting of the floating offshore platform can be effectively reduced, thereby enhancing the overall stability of the floating offshore platform.

[0037] It can effectively reduce the impact of impact forces on floating offshore platforms and offshore chain stop devices, protect floating offshore platforms and offshore chain stop devices, and reduce the risk of failure and damage.
