Description

Technical Field

[0001] This utility model relates to the field of marine wind power equipment technology, and more specifically, to a marine wind turbine pile ocean current vibration reduction device. Background Technology

[0002] In recent years, against the backdrop of the global energy structure accelerating its transformation towards cleaner and lower-carbon energy, offshore wind power, as a clean energy source with abundant reserves and sustainable development, has received widespread attention and vigorous development from countries around the world. With the continuous expansion of the scale of offshore wind farm construction, the importance of offshore wind turbine piles as the basic support structure for offshore wind turbine generators is self-evident. Offshore wind turbine piles not only have to bear the huge weight of the wind turbine generators, but also have to withstand the combined effects of complex marine environmental loads such as waves, wind and currents over a long period of time.

[0003] Among numerous environmental factors, ocean currents have a particularly significant impact on offshore wind turbine piles. Ocean currents are characterized by variable velocity and direction, and their continuous and uneven impacts cause periodic vibrations in wind turbine piles. Traditional offshore wind turbine pile designs lack sufficient attention to and targeted solutions for vibrations caused by ocean currents. They typically rely solely on the pile's own structure to resist the impact of ocean currents, lacking effective vibration reduction measures. This design makes wind turbine piles highly susceptible to structural fatigue damage under long-term ocean current action. Fatigue damage not only significantly shortens the service life of wind turbine piles but may also cause loosening of connecting components, seriously threatening the operational safety of offshore wind power systems. In extreme cases, it can even cause wind turbine piles to collapse, paralyzing the entire power generation system and causing incalculable economic losses to offshore wind power projects.

[0004] Although some vibration damping devices for offshore wind turbine piles have emerged on the market, these devices generally suffer from complex installation. This complexity not only increases the manufacturing difficulty and cost of the devices but also makes subsequent maintenance extremely cumbersome, requiring significant manpower, material resources, and financial investment, and causing inconvenience to workers. Therefore, we propose an ocean current vibration damping device for offshore wind turbine piles. Utility Model Content

[0005] The purpose of this invention is to provide a current vibration reduction device for marine wind turbine piles to address the deficiencies mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A current damping device for offshore wind turbine piles includes a wind turbine pile and a fixed platform positioned at the top of the wind turbine pile. Multiple current damping components are arranged in a ring at equal intervals on the outside of the wind turbine pile. Each current damping component includes a rust-proof vertical guide rail detachably mounted on the fixed platform. A sliding sleeve is slidably connected to the rust-proof vertical guide rail. A support seat is fixedly mounted on the side of the sliding sleeve. A first damping rod is provided between the support seat and the top rod of the rust-proof vertical guide rail. An arc-shaped flexible buffer plate is provided on one side of the rust-proof vertical guide rail. A support rod is fixedly mounted on the side of the support seat. The support rod and the arc-shaped flexible buffer plate are hinged together by multiple connecting rods. A second damping rod is hinged between the upper connecting rod and the support rod.

[0008] Preferably, the rust-proof vertical guide rail is arranged vertically, and a limit base is fixedly installed at the bottom end of the rust-proof vertical guide rail.

[0009] Preferably, a fixing seat is fixedly installed at the top of the rust-proof vertical guide rail, and the fixing seat is fixedly installed on the fixing platform by multiple fastening bolts.

[0010] Preferably, the size of the sliding sleeve is adapted to the size of the rust-proof vertical guide rail, and the outer diameter of the limiting base is larger than the inner diameter of the sliding sleeve.

[0011] Preferably, one end of the connecting rod is fixedly installed on the inner side of the arc-shaped flexible buffer plate, and the other end of the support rod is fixedly installed with a hinged end, and the other end of the connecting rod is hinged to the hinged end.

[0012] Preferably, the support rod is inclined upward at 45 to 60 degrees, and the cross-section of the arc-shaped flexible buffer plate is arc-shaped.

[0013] Preferably, one end of the second damping rod is hinged to the connecting rod located above, and the other end of the second damping rod is hinged to the support rod.

[0014] Preferably, a screw plate is fixedly installed on the top surface of the support base, an upper end plate is fixedly installed on the side of the top rod of the rust-proof vertical guide rail, and the first damping rod is installed between the screw plate and the upper end plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model, by setting a combination of rust-proof vertical guide rail, sliding sleeve and first damping rod, allows the sliding sleeve to slide up and down along the rust-proof vertical guide rail when the ocean current impacts the arc-shaped flexible buffer plate, and the first damping rod to buffer and consume part of the impact energy, thus achieving the initial buffering of the ocean current impact and reducing the impact intensity of the wind turbine pile.

[0017] 2. This utility model uses a support rod, multiple connecting rods, and an arc-shaped flexible buffer plate hinged together. A second damping rod is set between the upper connecting rod and the support rod. When the arc-shaped flexible buffer plate is impacted and displaced, the connecting rods move in coordination, and the second damping rod further absorbs the impact energy, realizing secondary buffering and dispersion of the impact energy, thereby achieving the effect of weakening the impact force of ocean currents in all directions and reducing the vibration of wind turbine piles.

[0018] 3. This utility model facilitates the installation and maintenance of the device by detachably installing the rust-proof vertical guide rail on the fixed platform. The arc-shaped design of the arc-shaped flexible buffer plate increases the stress area and disperses the impact force. The components of the overall structure cooperate with each other, and the overall structure is relatively simple and easy to install. This enables the device to be used stably in the complex marine environment, thereby extending the service life of the wind turbine piles and ensuring the stable operation of marine wind power equipment.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Please see Figures 1-4 This utility model provides a technical solution: a marine wind turbine pile ocean current vibration reduction device, including a wind turbine pile 1 and a fixed platform 10 set at the top of the wind turbine pile 1. Multiple ocean current vibration reduction components 2 arranged in a ring at equal intervals are provided on the outside of the wind turbine pile 1, so that when the ocean current impacts from all directions, it can be effectively buffered by the ocean current vibration reduction components 2, thereby reducing the impact force of the ocean current on the wind turbine pile 1 in all directions and improving the comprehensiveness and stability of vibration reduction.

[0029] Specifically, the ocean current vibration damping component 2 includes a rust-proof vertical guide rail 21 that can be detachably installed on the fixed platform 10. A fixing seat 20 is fixedly installed at the top of the rust-proof vertical guide rail 21. The fixing seat 20 has a U-shaped cross section. The fixing seat 20 is first snapped onto the fixed platform 10, and then the fixing seat 20 is fixedly installed on the fixed platform 10 by multiple fastening bolts. This ensures that the structure between the fixing seat 20 and the fixed platform 10 is more robust and stable, and at the same time makes the device more convenient to install, repair and replace, greatly reducing the difficulty and cost of later maintenance.

[0030] In this embodiment, the rust-proof vertical guide rail 21 is vertically arranged, and a sliding sleeve 22 is slidably connected to the rust-proof vertical guide rail 21. A support base 221 is fixedly installed on the side of the sliding sleeve 22, and a limiting base 211 is fixedly installed at the bottom of the rust-proof vertical guide rail 21. The size of the sliding sleeve 22 is adapted to the size of the rust-proof vertical guide rail 21. The outer diameter of the limiting base 211 is larger than the inner diameter of the sliding sleeve 22, so that the sliding sleeve 22 can slide smoothly along the rust-proof vertical guide rail 21, while preventing the sliding sleeve 22 from detaching from the guide rail, thus ensuring the stability of the vibration damping structure movement.

[0031] Specifically, a first damping rod 25 is provided between the support base 221 and the top rod of the rust-proof vertical guide rail 21. When the sliding sleeve 22 slides up and down due to the impact of the ocean current, the first damping rod 25 can effectively buffer and consume part of the impact energy, reducing the impact intensity of the wind turbine pile 1.

[0032] Furthermore, an arc-shaped flexible buffer plate 27 is provided on one side of the rust-proof vertical guide rail 21, and a support rod 26 is fixedly installed on the side of the support base 221. The support rod 26 and the arc-shaped flexible buffer plate 27 are hinged together by multiple connecting rods 28. A second damping rod 29 is hinged between the upper connecting rod 28 and the support rod 26. One end of the connecting rod 28 is fixedly installed on the inner side of the arc-shaped flexible buffer plate 27, so that the arc-shaped flexible buffer plate 27 can flexibly respond to the impact of ocean currents and effectively disperse the impact force. A hinged end 261 is fixedly installed at the other end of the support rod 26, and the other end of the connecting rod 28 is hinged to the hinged end 261. One end of the second damping rod 29 is hinged to the connecting rod 28 located above, and the other end of the second damping rod 29 is hinged to the support rod 26. When the arc-shaped flexible buffer plate 27 is impacted and drives the connecting rod 28 to move, the second damping rod 29 further consumes the impact energy and works in synergy with the first damping rod 25 to significantly enhance the vibration reduction performance of the device.

[0033] Furthermore, the support rod 26 is inclined upwards at 45 to 60 degrees, making it easier for the support rod 26 to slide upwards under force. At this time, the first damping rod 25 can be used for vibration reduction protection. The arc-shaped flexible buffer plate 27 has an arc-shaped cross-section and can be made of high-strength, wear-resistant, and highly flexible rubber or polymer materials. This allows the arc-shaped flexible buffer plate 27 to deform to a certain extent under the action of water flow, converting some of the impact energy into its own elastic potential energy, thereby buffering the direct impact of ocean currents on the wind turbine piles, reducing the vibration of the pile body, and so on. Figure 4 As shown, multiple arc-shaped flexible buffer plates 27 can be joined together to form a ring, which protects the wind turbine pile 1 inside and achieves a good effect of resisting ocean currents and reducing vibration.

[0034] It is worth noting that a screw plate 24 is fixedly installed on the top surface of the support base 221, and an upper end plate 23 is fixedly installed on the side of the top rod of the rust-proof vertical guide rail 21. The first damping rod 25 is installed between the screw plate 24 and the upper end plate 23, which facilitates the fixed installation of the first damping rod 25.

[0035] When using the ocean current vibration reduction device for marine wind turbine piles of this utility model, the fixing seats 20 of multiple ocean current vibration reduction components 2 are installed on the fixing platform 10 at the top of the wind turbine pile 1 using fastening bolts, ensuring that the components are arranged in a ring with equal spacing, thus completing the installation operation of the ocean current vibration reduction components 2.

[0036] When the ocean current impacts the wind turbine pile 1, the arc-shaped flexible buffer plate 27 deforms first to absorb some of the impact energy. At the same time, the impact force drives the connecting rod 28 to move, and the second damping rod 29 consumes some of the energy. In addition, the support seat 221 slides up and down along the anti-rust vertical guide rail 21 with the sliding sleeve 22, and the first damping rod 25 further absorbs and buffers the energy, providing all-round protection for the wind turbine pile 1 and reducing the impact of the ocean current.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
