[0033] like Figure 1 and Figure 2 As shown, the conduit assembly of this embodiment includes: a support pile 10, a mounting column 20, a lifting assembly 30, and a drive structure 40. The mounting column 20 is located above the support pile 10. The lifting assembly 30 is disposed at the top of the support pile 10, and the bottom of the mounting column 20 is movably disposed on the lifting assembly 30. The drive structure 40 is disposed between the support pile 10 and the mounting column 20 to allow the mounting column 20 to move relative to the support pile 10.

[0034] The technical scheme of the present application is applied to a guide pipe assembly, which comprises a support pile 10, a mounting column 20, a lifting assembly 30 and a driving structure 40. The top of the support pile 10 is provided with the lifting assembly 30, and the bottom of the mounting column 20 is arranged on the lifting assembly 30. The driving structure 40 is arranged between the support pile 10 and the mounting column 20, and can drive the mounting column 20 to lift relative to the support pile 10. Through the above arrangement, the support pile 10 can support the mounting column 20. The driving structure 40 can drive the mounting column 20 to lift relative to the support pile 10, so that when in a harsh environment, the mounting column 20 can be driven by the driving structure 40 to move towards the support pile 10, thereby reducing the overall height of the guide pipe assembly, so that the rigidity of the guide pipe assembly is better, the overall load is reduced, the anti-deformation ability of the guide pipe assembly is improved, and because the overall height of the guide pipe assembly can be reduced, the stress on the support pile 10 can also be reduced, thereby the stability of the support pile 10 is better, so that the stability of the guide pipe assembly is better. Therefore, the technical scheme of the present application effectively solves the problem of large stress on the pile leg of the guide pipe assembly in the related art in a harsh environment.

[0035] The harsh environment mainly refers to a stormy sea environment and an environment with large waves, of course, it can also be other environments.

[0036] The length of the mounting column is between 10 meters and 15 meters.

[0037] As shown in Figure 2 and Figure 3 in the present embodiment, the lifting assembly 30 comprises an outer cylinder 31, and the driving structure 40 comprises a jack 41 located in the outer cylinder 31. The jack 41 is arranged on the support pile 10, and the telescopic rod of the jack 41 is connected with the mounting column 20. The outer cylinder 31 can protect the jack 41 arranged in the outer cylinder 31 from corrosion. The jack 41 is arranged on the support pile 10, so that the support pile 10 can support the jack 41, and when the telescopic rod of the jack 41 moves, the mounting column 20 can be driven to move. The telescopic rod of the jack 41 drives the mounting column 20 to move, so that the overall height of the guide pipe assembly can be raised or lowered, and then in a harsh environment, the overall height of the guide pipe assembly can be reduced, so that the stress on the support pile 10 can be reduced, thereby improving the resistance of the guide pipe assembly. The jack 41 not only can provide sufficient driving force to ensure the mounting column 20 to lift stably, but also can protect the jack 41 from external environment erosion, prolong the service life, and be suitable for the guide pipe assembly exposed to seawater for a long time. In actual application, the built-in jack 41 can effectively resist seawater corrosion and marine biological erosion, reduce the maintenance frequency, and reduce the operating cost. Especially in deep sea and extreme climate conditions, the advantages of this design are more obvious.

[0038] A first partition plate is arranged at the top of the support pile 10, and the outer periphery of the first partition plate is in contact with the inner surface of the outer cylinder 31. In this way, seawater can be isolated to prevent seawater from entering the outer cylinder 31 and corroding the jack 41.

[0039] When encountering severe wind, the telescopic rod of the jack can be lowered to reduce the overall height of the guide pipe assembly and reduce the overall wind load. When the wind load is small, the telescopic rod of the jack can be raised to increase the height of the rotating shaft of the impeller of the wind turbine, thereby increasing the power generation and improving the efficiency.

[0040] The jack can also be a threaded sleeve and a threaded rod to drive the mounting column to rise and fall.

[0041] The guide pipe assembly further comprises a controller capable of controlling the operation of the jack 41 to extend and retract the telescopic rod of the jack.

[0042] As shown in Figure 3 In the present embodiment, the lifting assembly 30 further comprises an inner cylinder 32, the bottom of the mounting column 20 is arranged on the inner cylinder 32, the bottom of the outer cylinder 31 is connected with the support pile 10, and the inner cylinder 32 is connected between the telescopic rod of the jack 41 and the bottom of the mounting column 20. The inner cylinder 32 is movably arranged in the outer cylinder 31, and the bottom of the mounting column 20 is arranged on the inner cylinder 32, so that when the telescopic rod of the jack arranged in the outer cylinder 31 extends and retracts, the inner cylinder 32 can drive the mounting column 20 to rise and fall. The cooperation of the inner cylinder 32 and the outer cylinder 31 can effectively enhance the overall stability of the guide pipe assembly, prevent deviation or shaking during lifting, and be suitable for offshore environments with large waves. The double-cylinder structure of the inner cylinder 32 and the outer cylinder 31 can significantly improve the ability of the guide pipe assembly to resist waves, ensuring the stability and safety of the installation platform even in severe offshore conditions, and being suitable for offshore wind farms and oil drilling platforms that need to work stably in waves.

[0043] A second partition plate is arranged at the bottom of the inner cylinder 32, the second partition plate is in abutment with the inner surface of the outer cylinder 31, and the telescopic rod of the jack 41 is in abutment with the second partition plate, so that seawater can be isolated to prevent seawater from entering between the first partition plate and the second partition plate and corroding the jack 41.

[0044] When the outer cylinder and the support pile are connected and the inner cylinder and the mounting column are connected, welding can be used.

[0045] As shown in Figure 4 The outer periphery of the inner cylinder 32 is provided with a connecting plate and a sliding plate, the connecting plate is connected between the sliding plate and the outer surface of the inner cylinder 32, the inner surface of the outer cylinder 31 is provided with a first sliding groove and a second sliding groove, the width of the second sliding groove is smaller than the width of the first sliding groove, the sliding plate slides in the first sliding groove, and the connecting plate slides in the second sliding groove.

[0046] As Figure 2 and Figure 3 shown, in this embodiment, the lifting assembly 30 further includes reinforcing ribs 33 arranged between the side of the first mounting column 20 and the inner wall of the inner cylinder 32. By arranging the reinforcing ribs, the connection strength of the first mounting column 20 and the inner cylinder 32 is better, and then the telescopic rod of the jack 41 can more stably drive the mounting column 20 to move through the inner cylinder 32. The arrangement of the reinforcing ribs 33 can significantly improve the connection strength between the mounting column 20 and the inner cylinder 32, enhance the rigidity of the overall structure, and be suitable for supporting the guide pipe assembly bearing heavy load, such as large offshore wind power equipment. By arranging the reinforcing ribs 33, not only the load-bearing capacity of the inner cylinder 32 is improved, but also the force transmission path is optimized, so that the guide pipe assembly can be more stable when bearing the weight of large equipment, reducing the risk of structural deformation, suitable for supporting offshore wind towers and heavy oil equipment, and ensuring the safe operation of the equipment.

[0047] As Figure 3 shown, in this embodiment, the reinforcing ribs 33 include a plurality of reinforcing ribs 33, each of which extends along the radial direction of the inner cylinder 32. By arranging a plurality of reinforcing ribs 33, the connection between the bottom of the mounting column 20 and the inner cylinder 32 is more stable, and then the jack 41 can more stably drive the inner cylinder 32 to move, so that the inner cylinder 32 can drive the outer cylinder 31 to move when moving.

[0048] It should be noted that the plurality of reinforcing ribs 33 are arranged uniformly. The uniform distribution of the plurality of reinforcing ribs 33 can make the load more evenly distributed, further improve the stability and load-bearing capacity of the structure, and be suitable for offshore oil drilling platforms that require high stability. This design makes the guide pipe assembly can bear greater transverse and longitudinal load, especially during the installation and use of the drilling platform, which can effectively reduce the structural inclination or damage caused by uneven load, improve the reliability and safety of the platform.

[0049] Concrete grouting is carried out between the plurality of reinforcing ribs 33, the inner surface of the inner cylinder 32 and the outer surface of the mounting column 20, which makes the connection between the mounting column 20 and the inner cylinder 32 more stable.

[0050] When concrete grouting is carried out, it can be completed through pipes. The pipe openings are reserved on the outer cylinder 31 and the inner cylinder 32 to facilitate the flow of concrete.

[0051] As Figure 2As shown, in this embodiment, the lifting assembly 30 further includes a gear 34 and a rack meshing with the gear 34. The gear 34 is rotatably disposed on the outer surface of the inner cylinder 32, and the rack is disposed on the inner surface of the outer cylinder 31. The gear 34 and the rack can mesh, and the gear 34 can slide on the outer surface of the inner cylinder 32, thus making the relative sliding between the inner cylinder 32 and the outer cylinder 31 smoother when the inner cylinder 32 slides relative to the outer cylinder 31.

[0052] Of course, in other embodiments, the gear 34 may also be rotatably disposed on the inner surface of the outer cylinder 31, and the rack may be disposed on the outer surface of the inner cylinder 32.

[0053] A water-stop structure is provided between the top of the outer cylinder 31 and the outer surface of the inner cylinder 32 to prevent water from entering between the inner cylinder 32 and the outer cylinder 31 and corroding the gear 34 and rack.

[0054] Gears and racks may not be used between the inner and outer cylinders; instead, chains, slide rails, rollers, or other structures can be used.

[0055] like Figure 3 As shown, in this embodiment, the jacks 41 include multiple jacks spaced apart. These multiple spaced jacks 41 can simultaneously move the inner cylinder 32 relative to the outer cylinder 31, making the movement of the inner cylinder 32 relative to the outer cylinder 31 easier. By using multiple spaced jacks 41, a more uniform supporting force can be provided when the mounting column 20 is raised and lowered, reducing structural stress concentration and making it suitable for the precise installation of offshore wind turbine towers.

[0056] It should be noted that multiple jacks 41 are evenly distributed on top of the support pile. The number of jacks is between three and eight, specifically, it can be three, four, six, or eight; in this embodiment, four jacks are used. Of course, other numbers are also possible.

[0057] A reinforcing space is formed between any two adjacent reinforcing ribs 33, and a jack 41 is installed below each reinforcing space. This makes the force applied by the jack 41 more stable.

[0058] Strain sensors are installed on the telescopic rod of the jack 41 and at the bottom of the inner cylinder 32 to detect the stress of the conduit assembly and prevent stress concentration from causing buckling.

[0059] like Figures 5 to 8As shown, the pipe rack of the embodiment includes a mounting platform 100 and a plurality of pipe assemblies arranged below the mounting platform 100, the pipe assemblies being the pipe assemblies described above. In use, the driving structure 40 can drive the mounting column 20 to ascend or descend relative to the support pile 10, so that when the pipe assemblies are in a harsh environment, the mounting column 20 can be close to the support pile 10, so that the height of the pipe assemblies can be reduced, thereby reducing the stress of the pipe assemblies in the harsh environment, so that the stress of the support pile 10 can be reduced, that is, the position of the support pile 10 is more stable. The pipe rack with the pipe assemblies described above also has the advantages described above.

[0060] In the installation of the pipe rack, the plurality of mounting columns 20 and the inner cylinder 32 can be connected on land, and then transported to the sea as a whole and connected with the support pile 10. Alternatively, the mounting column can be connected to the inner cylinder at sea.

[0061] It should be noted that the pipe rack also includes a plurality of diagonal braces, at least one diagonal brace being connected between adjacent two mounting columns 20, so that the connection of the plurality of pipe assemblies is more stable.

[0062] For deep-sea areas, a multi-layer stacking method is used, that is, a plurality of lifting assemblies are used for stacking installation, which facilitates installation in deep-sea areas, and the height of the pipe rack is changed by a plurality of jacks to effectively reduce the load and reduce the overall stress of the pipe rack. In addition, multiple grouting is also used to reduce the amount of steel used.

[0063] The pipe rack in the prior art has high cost, is close to the shore, and cannot be arranged in deep-sea areas. Due to large waves and strong winds in deep-sea areas, the environment is harsh, and the pipe rack foundation bears a large load, and the wave load borne is significantly increased. Compared with other structures, the pipe rack foundation is often applied to places with a water depth of more than 30 m. Moreover, the maintenance cost of the pipe rack is large.

[0064] The power generation device of the embodiment includes a pipe rack and a power generation structure arranged on the pipe rack, and the pipe rack is the pipe rack described above. In use, the driving structure 40 can drive the mounting column 20 to ascend or descend relative to the support pile 10, so that when the pipe assemblies are in a harsh environment, the mounting column 20 can be close to the support pile 10, so that the height of the pipe assemblies can be reduced, thereby reducing the stress of the pipe assemblies in the harsh environment, so that the stress of the support pile 10 can be reduced, that is, the position of the support pile 10 is more stable.
