[0029] Sacrificial anodes are widely used in the anti-corrosion protection of the foundations of offshore wind turbines. Due to the influence of the complex marine environment, a layer of marine attachments is likely to adhere to the surface of the sacrificial anode, seriously affecting the contact area between the surface of the sacrificial anode and seawater, and greatly reducing the reliability of the sacrificial anode anti-corrosion system. In the prior art, the sacrificial anodes of the wind turbine foundation are usually cleaned by regular manual cleaning to remove the marine attachments on the surface. This method requires regular arrangement of divers to go underwater for inspection and cleaning, and the work safety risk is relatively high. Therefore, how to optimize the cleaning method of the sacrificial anode to make the cleaning of the sacrificial anode more efficient and safe has become an urgent problem to be solved in this field.

[0030] The following refers to Figure 1 - Figure 2 Describe a cleaning device for a wind turbine sacrificial anode according to an embodiment of the present invention.

[0031] The cleaning device 1 for a wind turbine sacrificial anode according to the present invention includes a wind turbine base 11, a pump body 12, a cleaning pipeline, and a sacrificial anode 16. A wind turbine platform 111 is formed on the wind turbine base 11; the pump body 12 is arranged on the wind turbine platform 111 and is connected to the wind turbine base 11; the cleaning pipeline is arranged on the wind turbine base 11 and has an input end and an output end 1433. The cleaning pipeline is connected to the pump body 12 and sucks seawater through the input end, and sprays seawater outward through the output end 1433; the sacrificial anode 16 is arranged on the wind turbine base 11 and is facing the output end 1433.

[0032] Specifically, the wind turbine base 11 serves as the basic structure of the entire cleaning device 1, is used to realize wind power generation, and supports and fixes other structures. Among them, a wind turbine platform 111 is arranged on the wind turbine base 11, and the pump body 12 is arranged on the wind turbine platform 111 and is closely connected to the wind turbine base 11. The pump body 12 can obtain power from inside the wind turbine base 11, thereby absorbing seawater through the input end of the cleaning pipeline, and spraying the seawater onto the surface of the sacrificial anode 16 through the output end 1433 to clean the marine attachments on the surface of the sacrificial anode 16. By setting the pump body 12 and the cleaning pipeline to cooperate, the surface of the sacrificial anode 16 is automatically cleaned with seawater, without the need for manual timing cleaning, making the cleaning of the sacrificial anode 16 more automated and the cleaning process safer.

[0033] The cleaning device 1 for a wind turbine sacrificial anode according to the present invention arranges the pump body 12 on the wind turbine base 11. The pump body 12 can directly obtain power from inside the wind turbine base 11. After the pump body 12 is powered on, it cooperates with the input end of the cleaning pipeline to suck seawater into the cleaning pipeline. The pump body 12 can pressurize the seawater and spray the seawater onto the surface of the sacrificial anode 16 through the output end 1433, improving the cleaning effect on the surface of the sacrificial anode 16. By setting the pump body 12 and the cleaning pipeline to automatically clean the surface of the sacrificial anode 16 with seawater, the cleaning efficiency is improved, and the safety of the cleaning process is also improved.

[0034] According to some embodiments of the present utility model, the cleaning pipeline includes an input pipeline 13 and an output pipeline. The input pipeline 13 extends along the extending direction of the fan base 11. One end of the input pipeline 13 is connected to the pump body 12, and the other end extends below the sea level and is configured as an input end; one end of the output pipeline is connected to the pump body 12, and the other end extends to at least a part of the outer periphery of the sacrificial anode 16 and is configured as an output end 1433.

[0035] Specifically, the input pipeline 13 extends along the extending direction of the fan base 11 to ensure that the pipeline can be stably fixed on the fan base 11 and change with its shape. One end of the input pipeline 13 is closely connected to the pump body 12 to ensure that the pump body 12 can smoothly suck seawater into the pipeline. The other end of the input pipeline 13 extends below the sea level and is configured as an input end. This design ensures that seawater can be effectively sucked in, providing an adequate source of seawater for subsequent cleaning. One end of the output pipeline is connected to the pump body 12. Through the pressurization of the pump body 12, seawater can flow in the pipeline and finally be ejected. The other end of the output pipeline extends to at least a part of the outer periphery of the sacrificial anode 16 and is configured as an output end 1433. This design ensures that seawater can be directly and evenly sprayed on the surface of the sacrificial anode 16 to achieve a comprehensive cleaning effect. In particular, when the output pipeline can be arranged around the outer periphery of the sacrificial anode 16, it can ensure that all parts of the sacrificial anode 16 can be fully cleaned. Such a design not only ensures the stability and reliability of the cleaning device 1, but also improves the cleaning efficiency and effect, enabling the sacrificial anode 16 to maintain its good performance and extend its service life.

[0036] According to some embodiments of the present utility model, the output pipeline includes: a main pipeline 141, the main pipeline 141 is disposed around the outer periphery of the fan base 11 and is disposed on the fan platform 111. The main pipeline 141 is connected to the pump body 12 and a first output port is provided on the main pipeline 141; an intermediate pipeline 142, the intermediate pipeline 142 extends along the extending direction of the fan base 11 and one end of the intermediate pipeline 142 is connected to the output port, and the other end forms a second output port; a branch pipeline 143, the branch pipeline 143 is configured to be multiple, one end of each branch pipeline 143 is connected to the second output port, and the other end extends to at least a part of the outer periphery of the sacrificial anode 16. A plurality of output ends 1433 facing the sacrificial anode 16 are spaced apart on each branch pipeline 143.

[0037] Specifically, the main pipeline 141 is disposed around the outer periphery of the fan base 11 and is specifically located on the fan platform 111. Such a design enables the main pipeline 141 to be conveniently connected to various parts of the fan base 11 while ensuring the compact structure of the entire cleaning device 1. The main pipeline 141 is directly connected to the pump body 12, thereby receiving the pressurized seawater from the pump body 12. A first outlet is provided on the main pipeline 141 as the starting point for the seawater to flow to the subsequent pipelines. The branch pipelines 143 are configured in multiple numbers to ensure that all parts of the sacrificial anode 16 can be fully cleaned. One end of each branch pipeline 143 is connected to the second outlet of the intermediate pipeline 142, and the other end extends to at least a part of the outer periphery of the sacrificial anode 16. On each branch pipeline 143, a plurality of output ends 1433 facing the sacrificial anode 16 are provided at intervals. These output ends 1433 can evenly spray the pressurized seawater on the surface of the sacrificial anode 16, thereby achieving a comprehensive and uniform cleaning effect. Through such a design, the entire cleaning device 1 can not only ensure that all parts of the sacrificial anode 16 can be fully cleaned, but also improve the cleaning efficiency and effect. At the same time, such a structural design also makes the entire cleaning device 1 more stable and reliable.

[0038] According to some embodiments of the present invention, the branch pipeline 143 includes: a first branch 1431, the first branch 1431 is perpendicular to the intermediate pipeline 142 and the middle part of the first branch 1431 is connected to the second outlet; a second branch 1432, the second branch 1432 is configured into two and is respectively connected to both ends of the first branch 1431, and the two second branches 1432 respectively extend along the extending direction of the fan base 11 and a plurality of output ends 1433 are respectively provided at intervals on each second branch 1432.

[0039] Specifically, the first branch 1431 extends vertically from the second outlet, and the middle part thereof is tightly connected to the second outlet of the intermediate pipeline 142. This vertical design enables the seawater to be evenly distributed into the two second branches 1432. The second branch 1432 is configured into two, and they are respectively connected to both ends of the first branch 1431. Such a design enables the two second branches 1432 to respectively extend along the extending direction of the fan base 11, ensuring that the seawater can cover different areas of the sacrificial anode 16. On each second branch 1432, a plurality of output ends 1433 are provided at intervals. These output ends 1433 ensure that the seawater can be evenly and densely sprayed on the surface of the sacrificial anode 16, achieving a comprehensive cleaning effect. Through this design, the cleaning device 1 of the sacrificial anode 16 can more effectively cover all parts of the sacrificial anode 16, improving the cleaning efficiency and effect. At the same time, such a structure also makes the entire device more stable and reliable, reducing the maintenance cost.

[0040] According to some embodiments of the present utility model, the pump body 12 is configured as a high-pressure water pump, and the output end 1433 is configured as a high-pressure nozzle.

[0041] Specifically, the pump body 12 is specially designed as a high-pressure water pump. This high-pressure water pump can generate higher water pressure, making the seawater output through the cleaning pipeline have higher impact force and cleaning effect. The output end 1433 is configured as a high-pressure nozzle, which can spray the high-pressure seawater in a finer and denser water flow form, thus ensuring that the surface of the sacrificial anode 16 can be cleaned more evenly and deeply. By adopting the design of the high-pressure water pump and the high-pressure nozzle, the cleaning device 1 can significantly improve the cleaning efficiency and effect on the sacrificial anode 16. The high-pressure water flow can not only easily remove the dirt and biological attachments on the surface of the sacrificial anode 16, but also penetrate into the inaccessible gaps and holes to achieve more thorough cleaning. In addition, the high-pressure water flow can also remove some stubborn attachments to ensure the performance of the sacrificial anode 16 is restored and maintained.

[0042] According to some embodiments of the present utility model, the first output ports are configured as multiple ones spaced along the extending direction of the main pipeline 141, and the intermediate pipelines 142 are configured as multiple ones corresponding to the first output ports.

[0043] Specifically, along the extending direction of the main pipeline 141, multiple first output ports are provided. Such a design enables seawater to enter the intermediate pipelines 142 from multiple positions simultaneously, improving the cleaning efficiency and coverage area of the entire system. The number of the intermediate pipelines 142 corresponds to that of the first output ports and is also configured as multiple ones. Each intermediate pipeline 142 is connected to a specific first output port to ensure that the seawater can be evenly distributed into each branch pipeline 143. Through this design, the cleaning device 1 can more comprehensively cover each part of the sacrificial anode 16 and improve the cleaning effect. At the same time, the arrangement of the multiple intermediate pipelines 142 and the branch pipelines 143 also makes the system more flexible and can be adjusted and optimized according to the actual position and shape of the sacrificial anode 16.

[0044] According to some embodiments of the present utility model, the cleaning device 1 further includes: a first support member 151, the first support member 151 is configured as multiple ones and is spaced on the fan platform 111, one ends of the multiple first support members 151 are arranged on the fan platform 111, and the other ends support the bottom of the output pipeline.

[0045] Specifically, the first support members 151 are designed to be multiple, and they are arranged at intervals on the fan platform 111. This layout can ensure that the output pipeline is evenly and stably supported on the fan platform 111. One end of each first support member 151 is fixed to the fan platform 111, and the other end directly supports the bottom of the output pipeline. This design ensures the stability of the output pipeline, and it can maintain its position and shape even under the action of pressurized seawater, avoiding performance degradation or damage caused by vibration or deformation. By introducing the first support members 151, the cleaning device 1 not only improves the stability of the output pipeline, but also enhances the reliability and durability of the entire system. This helps to ensure that the sacrificial anode 16 of the fan can be continuously and effectively cleaned, thereby maintaining its good performance and extending its service life.

[0046] According to some embodiments of the present invention, the cleaning device 1 further includes: a second support member 152, which is disposed on the radial outer periphery of the fan base 11 and extends perpendicular to the fan base 11, and a receiving hole for receiving the intermediate pipeline 142 is provided on the second support member 152.

[0047] Specifically, the second support member 152 is installed on the radial outer periphery of the fan base 11, and its extending direction is perpendicular to the fan base 11. Such a design enables the second support member 152 to effectively support and fix the output pipeline, especially in the intermediate pipeline 142 part, ensuring its stability during operation. On the second support member 152, receiving holes for specifically receiving the intermediate pipeline 142 are provided. The sizes and shapes of these receiving holes match those of the intermediate pipeline 142, so that the intermediate pipeline 142 can be tightly fixed therein, preventing it from moving or vibrating during use. By introducing the second support member 152 and the design of the receiving holes thereon, the cleaning device 1 further enhances the stability and reliability of the output pipeline. This not only helps to ensure that the sacrificial anode 16 is evenly and effectively cleaned, but also reduces the risk of equipment damage or performance degradation that may be caused by pipeline vibration or movement. At the same time, this design also makes the structure of the entire cleaning device 1 more compact and orderly, facilitating installation and maintenance.

[0048] According to some embodiments of the present invention, the second support member 152 is configured to be multiple.

[0049] Specifically, the second support members 152 are designed to be multiple and are distributed along the radial outer periphery of the fan base 11. Such a design ensures that the intermediate pipeline 142 is stably supported at multiple points, thereby further enhancing the stability and reliability of the entire cleaning device 1. By increasing the number of the second support members 152, the device can more evenly disperse the weight and force of the intermediate pipeline 142, reducing the damage of the support members or the deformation of the pipeline that may be caused by excessive force at a single point. At the same time, multiple support members can also provide a larger installation and adjustment space, enabling the output pipeline to be flexibly arranged according to the specific position and shape of the sacrificial anode 16 to meet different cleaning requirements. This design not only improves the cleaning effect but also enhances the adaptability and durability of the device.
