[0033] like Figure 1 and Figure 2 As shown, the catheter assembly of this embodiment includes: a support pile 10, a mounting column 20, a lifting assembly 30 and a driving structure 40. The mounting column 20 is located above the support pile 10. The lifting assembly 30 is arranged on the top of the support pile 10, and the bottom of the mounting column 20 is lifted and lowered on the lifting assembly 30. The driving structure 40 is arranged between the support pile 10 and the mounting column 20, so that the mounting column 20 can be lifted and lowered relative to the support pile 10.

[0034] Applying the technical solution of the present invention, the catheter assembly includes 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 a lifting assembly 30, and the bottom of the mounting column 20 is provided on the lifting assembly 30. A driving structure 40 is provided between the support pile 10 and the mounting column 20, and the driving structure 40 can drive the mounting column 20 to rise and fall relative to the support pile 10. Through the above-mentioned setting, the support pile 10 can support the mounting column 20. The driving structure 40 can drive the mounting column 20 to rise and fall 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 toward the support pile 10, thereby reducing the overall height of the catheter assembly, thereby making the rigidity of the catheter assembly better, reducing the overall load, and improving the anti-deformation ability of the catheter assembly, and because the overall height of the catheter assembly can be reduced, the force on the support pile 10 can also be reduced, thereby making the stability of the support pile 10 better, thereby making the stability of the catheter assembly better. Therefore, the technical solution of the present application effectively solves the problem that the pile legs of the catheter assembly in the related art are subjected to greater force in harsh environments.

[0035] The harsh environment mainly refers to the offshore storm environment and the environment with large waves, of course, it can also be other environments.

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

[0037] like Figure 2 and Figure 3 As shown, in this embodiment, the lifting assembly 30 includes an outer cylinder 31, and the driving structure 40 includes 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 to the mounting column 20. The outer cylinder 31 can protect the jack 41 arranged in the outer cylinder 31 to prevent the jack 41 from being corroded. The jack 41 is arranged on the support pile 10, so that the support pile 10 can support the jack 41, and then when the telescopic rod of the jack 41 moves, it can drive the mounting column 20 to move. The telescopic rod of the jack 41 drives the mounting column 20 to move, so that the overall height of the catheter assembly can be raised or lowered, and then the catheter assembly can reduce the force on the support pile 10 by lowering the overall height of the catheter assembly in a harsh environment, thereby improving the resistance of the catheter assembly. The jack 41 can not only provide sufficient driving force to ensure the smooth lifting of the mounting column 20, but also the built-in design of the jack 41 can protect the jack 41 from erosion by the external environment, prolong the service life, and is suitable for the catheter assembly exposed to seawater for a long time. In practical applications, the built-in jack 41 can effectively resist seawater corrosion and marine biological erosion, reduce maintenance frequency, and reduce operating costs. Especially in deep sea and extreme climate conditions, the advantages of this design are more obvious.

[0038] A first partition plate is provided on the top of the support pile 10, and the outer periphery of the first partition plate contacts 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 winds, the telescopic rod of the jack can be moved down to reduce the overall height of the duct assembly and reduce the overall wind load. When the wind load is small, the telescopic rod of the jack can be moved up to increase the height of the rotating shaft of the wind turbine's impeller, thereby increasing power generation and improving efficiency.

[0040] The jack can also be a threaded sleeve and a screw rod, through which the installation column is driven to rise and fall.

[0041] The catheter assembly further comprises a controller, which can control the operation of the jack 41 so as to extend and retract the telescopic rod of the jack.

[0042] like Figure 3 As shown, in this embodiment, the lifting assembly 30 also includes 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 to 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 is extended and retracted, the mounting column 20 can be driven to rise and fall through the inner cylinder 32. The coordinated use of the inner cylinder 32 and the outer cylinder 31 can effectively enhance the overall stability of the catheter assembly, prevent deviation or shaking during the lifting process, and is suitable for offshore environments with large winds and waves. This double cylinder structure of the inner cylinder 32 and the outer cylinder 31 can significantly improve the ability of the catheter assembly to resist wind and waves, and can ensure the stability and safety of the installation platform even under harsh offshore conditions, and is suitable for offshore wind farms and oil drilling platforms, etc., which need to maintain stable operation in wind and waves.

[0043] A second partition plate is provided at the bottom of the inner cylinder 32 , and the second partition plate abuts against the inner surface of the outer cylinder 31 , and the telescopic rod of the jack 41 abuts against the second partition plate, so that seawater can be isolated and prevented from entering between the first partition plate and the second partition plate and corroding the jack 41 .

[0044] Welding can be used to connect the outer cylinder to the supporting piles and the inner cylinder to the mounting columns.

[0045] like Figure 4 As shown, a connecting plate and a sliding plate are provided on the outer periphery of the inner cylinder 32, the connecting plate is connected between the sliding plate and the outer surface of the inner cylinder 32, a first sliding groove and a second sliding groove are provided on the inner surface of the outer cylinder 31, 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] like Figure 2 and Figure 3 As shown, in this embodiment, the lifting assembly 30 also includes a reinforcing rib 33, which is arranged between the side of the first mounting column 20 and the inner wall of the inner cylinder 32. By setting the reinforcing rib, the connection strength between the first mounting column 20 and the inner cylinder 32 is better, and then the telescopic rod of the jack 41 can drive the mounting column 20 to move more stably through the inner cylinder 32. The setting of the reinforcing rib 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 is suitable for the duct assembly that bears heavy loads, such as the support of large offshore wind power equipment. By setting the reinforcing rib 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 duct assembly can be more stable when bearing the weight of large equipment, reducing the risk of structural deformation, and is suitable for the support of offshore wind power towers and heavy oil equipment, etc., to ensure the safe operation of the equipment.

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

[0048] It should be noted that multiple reinforcing ribs 33 are evenly distributed. The even distribution of multiple reinforcing ribs 33 can make the load more evenly dispersed, further improve the stability and bearing capacity of the structure, and is suitable for offshore oil drilling platforms that require high stability. This design enables the catheter assembly to withstand greater lateral and longitudinal loads, especially during the installation and use of the drilling platform, which can effectively reduce the structural tilt or damage caused by uneven loads and improve the reliability and safety of the platform.

[0049] Concrete grouting is performed 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 carrying out concrete grouting, it can be completed through a pipeline. Both the outer cylinder 31 and the inner cylinder 32 are provided with a pipeline opening to facilitate the flow of concrete.

[0051] like Figure 2As shown, in this embodiment, the lifting assembly 30 further includes a gear 34 and a rack meshed 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, so that when the inner cylinder 32 slides relative to the outer cylinder 31, the relative sliding between the inner cylinder 32 and the outer cylinder 31 is smoother.

[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-stopping structure is provided between the top of the outer cylinder 31 and the outer surface of the inner cylinder 32 to prevent moisture from entering between the inner cylinder 32 and the outer cylinder 31 and corroding the gear 34 and the rack.

[0054] Gears and racks do not need to be arranged between the inner cylinder and the outer cylinder, and other structures such as chains, slide rails or rollers may be arranged.

[0055] like Figure 3 As shown, in this embodiment, the jacks 41 include a plurality of jacks 41 arranged at intervals. The plurality of jacks 41 arranged at intervals can simultaneously drive the inner cylinder 32 to move relative to the outer cylinder 31, so that the inner cylinder 32 can move relative to the outer cylinder 31 more easily. By using a plurality of jacks 41 arranged at intervals, a more uniform supporting force can be provided when the installation column 20 is raised or lowered, reducing the concentration of structural stress, and being suitable for the precise installation of offshore wind power towers.

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

[0057] A reinforcement space is formed between any two adjacent reinforcement ribs 33, and a jack 41 is disposed below each reinforcement space, so that the force applied by the jack 41 is more stable.

[0058] Strain sensors are arranged on the telescopic rod of the jack 41 and on the bottom of the inner cylinder 32 to detect the stress of the catheter assembly and prevent buckling caused by stress concentration.

[0059] like Figures 5 to 8As shown, the catheter rack of this embodiment includes a mounting platform 100 and a plurality of catheter assemblies arranged below the mounting platform 100, and the catheter assembly is the above-mentioned catheter assembly. When the above-mentioned catheter assembly is in use, the driving structure 40 can drive the mounting column 20 to rise and fall relative to the support pile 10, so that when the catheter assembly is in a harsh environment, the mounting column 20 can be close to the support pile 10, so that the height of the catheter assembly can be reduced, and then the force of the catheter assembly in the harsh environment can be reduced, so that the force of the support pile 10 can be reduced, that is, the position of the support pile 10 is more stable. The catheter rack with the above-mentioned catheter assembly also has the above-mentioned advantages.

[0060] When the jacket is installed, a plurality of mounting columns 20 and the inner cylinder 32 can be connected on land, and then transported as a whole to the sea and connected to the support piles 10. The mounting columns can also be connected to the inner cylinder at sea.

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

[0062] For deep sea areas, a multi-layer stacking method is adopted, that is, multiple lifting components are used and installed in a stacked manner to facilitate installation in deep sea areas. The height of the jacket is changed by multiple jacks to effectively reduce the load and the overall stress on the jacket. In addition, grouting is performed in multiple places to reduce the amount of steel used.

[0063] The existing jackets are expensive and close to the shore, so they cannot be deployed in deep sea areas. Due to the strong waves, strong winds and harsh environment in the deep sea, the jacket foundation bears a large load and the wave load is significantly increased. Compared with other structures, the jacket foundation is often used in places with a water depth of more than 30m. In addition, the maintenance cost of the jacket is high.

[0064] The power generation device of this embodiment includes a conductor frame and a power generation structure arranged on the conductor frame, and the conductor frame is the conductor frame mentioned above. When the conductor frame mentioned above is in use, the driving structure 40 can drive the installation column 20 to rise and fall relative to the support pile 10, so that when the conductor assembly is in a harsh environment, the installation column 20 can be close to the support pile 10, so that the height of the conductor assembly can be reduced, and then the force on the conductor assembly in the harsh environment can be reduced, so that the force on the support pile 10 can be reduced, that is, the position of the support pile 10 is more stable. The power generation device with the conductor frame mentioned above also has the above advantages.
