Description

Technical Field

[0001] The present invention relates to the field of wind power generation, and in particular to an anti-scouring system for offshore wind power pile foundations. Background Art

[0002] Wind power generation is the world's fastest-growing green energy technology. While onshore wind farm construction is rapidly developing, concerns have been raised about limitations to onshore wind energy utilization, such as large land footprints and noise pollution. Due to the abundant offshore wind energy resources and the feasibility of current technology, the ocean is poised to become a rapidly developing wind power market. Offshore wind farms in Europe and the United States are on the verge of large-scale development. my country's eastern coast boasts vast waters within a water depth of 50 meters and close proximity to power load centers (economically developed coastal areas with power shortages). As offshore wind farm technology matures, wind power is poised to become a key energy source for sustainable development in my country's eastern coastal regions. There are two main types of offshore wind turbine support technologies: bottom-fixed support and suspended support. There are three types of bottom fixed supports: gravity caisson foundation, single pile foundation, and tripod foundation. However, no matter which type of fixed pile foundation is used, it will be threatened by undercurrent and sediment scouring. The existing anti-scouring system structure of offshore wind power pile foundation is relatively simple. Since it is located on the seabed and is inconvenient to maintain, the sediment accumulated on the pile foundation is difficult to clean. At the same time, it is also impossible to better block the sediment carried by the undercurrent. Over time, the pile foundation is seriously damaged, and the wind power equipment is prone to collapse, causing serious economic losses. Summary of the Invention

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 The present invention provides a technical solution: an anti-scour system for an offshore wind turbine pile foundation, comprising a chassis 1, the chassis 1 being in contact with the seabed, and having anti-slip edge teeth 2 fixedly connected at equal intervals around the bottom of the chassis 1. The anti-slip edge teeth 2 along the bottom edge of the chassis 1 bite into the seabed, thereby preventing the equipment from sliding and displacing due to the influence of water flow. A diversion mechanism 3 is provided on the top of the chassis 1, and a mounting mechanism 4 is provided on the top of the diversion mechanism 3. Anti-loss mechanisms 5 are provided on both sides of the chassis 1.

[0023] The guide mechanism 3 includes a base 31, a mounting rod 32, a first guide ring 33, a second guide ring 34, and a spoiler 35. The base 31 is fixedly connected to the top center of the chassis 1, and the top of the base 31 is fixedly connected to the mounting rod 32. The bottom of the outer side of the mounting rod 32 is sleeved with a first guide ring 33, and the middle of the outer side of the mounting rod 32 is sleeved with a second guide ring 34. The spoiler 35 is rotatably connected to the outer side of the mounting rod 32 and located between the first guide ring 33 and the second guide ring 34. As shown in Figure 2, when the undercurrent of seawater contacts the spoiler impeller 3 At 5 o'clock, the turbulent impeller 35 charged by the undercurrent of seawater rotates, and the turbulent impeller 35 changes the direction of seawater flow while rotating, making it flow upward or downward. When the seawater flows downward, the water is guided and diffused by the first guide ring 33, so that the water flows to the top and around the chassis 1, and the impact force of the water washes away the mud and sand on the top of the chassis 1, preventing the accumulation of mud and sand from corroding the chassis 1. When the seawater flows upward, the water pressure below the turbulent impeller 35 is less than that above, and the water flow drives the mud and sand to flow upward, and is guided and diffused to the surroundings of the chassis 1 through the second guide ring 34, thereby achieving the effect of clearing the mud and sand.

[0024] Furthermore, the mounting mechanism 4 includes mounting holes 41, connecting screws 42, embedded sleeves 43, anti-retreat caps 44, and auger 45. Three mounting holes 41 are equidistantly excavated on the top of the chassis 1. The tops of the mounting holes 41 are threadedly connected with connecting screws 42. Three embedded sleeves 43 are provided at the bottom of the chassis 1. The tops of the embedded sleeves 43 are fixedly connected with anti-retreat caps 44. The outer sides of the embedded sleeves 43 are fixedly connected with auger 45. The anti-scour system for offshore wind power pile foundations is threadedly connected to the embedded sleeves 43 after passing through the chassis 1 through the connecting screws 42, so that the anti-scour system for offshore wind power pile foundations is fixed on the seabed. The mounting mechanism 4 facilitates better fixing of the equipment on the seabed surface to prevent the equipment from shaking or detaching.

[0025] Furthermore, the anti-loss mechanism 5 includes a mounting plate 51, a mounting basin 52, an insert plate 53, and a root extension hole 54. The mounting plates 51 are fixedly connected on both sides of the chassis 1. The top of the mounting plate 51 is equidistantly inlaid with mounting basins 52. The bottom of the mounting plate 51 is symmetrically fixed with insert plates 53 on both sides of the mounting basin 52. A root extension hole 54 is provided at the bottom of the mounting basin 52. The anti-loss mechanism 5 facilitates better reinforcement of the mud and sand on the seabed near the equipment to prevent the mud and sand from loosening and causing the equipment to shake and detach.

[0026] Furthermore, the anti-slip edge teeth 2 are triangular in structure and the curvature of the outer edge matches the curvature of the edge of the chassis 1, so as to better increase the stability of the device.

[0027] Furthermore, the base 31 is a truncated cone structure, which facilitates the auxiliary diversion function.

[0028] Furthermore, the outer sides of the first guide ring 33 and the second guide ring 34 are both arc-shaped structures, and the first guide ring 33 and the second guide ring 34 are symmetrical structures relative to the spoiler impeller 35, so as to facilitate better flow guidance.

[0029] Furthermore, the bottom of the embedded sleeve 43 is a conical structure, which facilitates better installation on the seabed surface.

[0030] Furthermore, seaweed or other marine plants are planted inside the installation basin 52, and the plant roots facilitate better reinforcement of the seabed mud and sand. At the same time, the formed seaweed or other marine plants can also play a role in shielding the mud and sand, preventing the mud and sand from impacting the pile foundation and causing corrosion and wear.

[0031] Furthermore, the bottom of the mounting plate 51 and the bottom of the chassis 1 are located in the same horizontal plane, which facilitates optimization of the equipment structure.

[0032] Furthermore, the top of the installation rod 32 is fixedly connected to a generator support rod 6 to install and support the top wind power generation equipment.

[0033] Specifically, during installation, first rotate and install the embedded sleeve 43 at a designated position on the seabed, then lower the chassis 1 above the embedded sleeve 43, align the mounting hole 41 with the embedded sleeve 43, and then use the connecting screw 42 to thread the embedded sleeve 43 through the mounting hole 41 to fix the device. Figure 2 As shown, when the undercurrent of seawater contacts the spoiler impeller 35, the undercurrent of seawater charges the spoiler impeller 35 to rotate, and the spoiler impeller 35 changes the direction of the seawater while rotating, so that it flows upward or downward. When the seawater flows downward, the water flows to the top of the chassis 1 and is diffused by the first guide ring 33, and the mud and sand on the top of the chassis 1 are washed away by the impact force of the water, so as to prevent the accumulation of mud and sand from corroding the chassis 1. When the seawater flows upward, the water pressure below the spoiler impeller 35 is less than that above, and the water flow drives the mud and sand to flow upward and passes through the second guide ring 3 4 is diverted to the surroundings of the chassis 1, thereby having the effect of clearing mud and sand. The top of the mounting plate 51 is equidistantly inlaid with mounting basins 52. The bottom of the mounting basins 52 is provided with root extension holes 54. Seaweed or other marine plants are planted inside the mounting basins 52. After the plant roots grow, they extend through the root extension holes 54 into the mud and sand on the seabed, which can reinforce the seabed mud and sand, preventing the mud and sand from loosening and causing the equipment to shake and fall off. At the same time, the formed seaweed or other marine plants can also block the mud and sand, preventing the mud and sand from impacting the pile foundation and causing corrosion and wear.

[0034] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
