Description

Technical Field

[0001] This application relates to the field of wind power equipment technology, and in particular to an offshore wind power foundation and an offshore wind turbine generator set. Background Technology

[0002] Wind energy, as a clean and renewable energy source, is being widely used globally. Offshore wind turbines are one of the important ways to utilize wind energy, and they typically consist of offshore wind turbine foundations. Offshore wind turbine foundations are built at sea; when sea ice forms, the ice can impact the foundations, causing ice-induced vibrations that can compromise the safety and stability of both the foundations and the offshore wind turbines.

[0003] In related technologies, upright flexible foundation technology and anti-ice cone technology are commonly used. Upright flexible foundations mainly rely on their stiffness and strength to directly resist sea ice impacts, but cannot avoid the impact of ice-induced vibrations on structural stability. Anti-ice cone technology reduces the direct impact of sea ice on wind turbine foundations by installing anti-ice cones near the sea surface; however, the presence of anti-ice cones increases the waterline area of ​​the wind turbine foundation, leading to a significant increase in wave loads. Therefore, a new type of offshore wind turbine foundation is urgently needed. Utility Model Content

The sea ice detector is used to detect the sea ice coverage in the wind farm area, and the moving detector is used to detect the vibration of the foundation body. The controller is communicatively connected to an ice and snow removal device and is used to control the start and stop of the ice and snow removal device.

[0013] In one possible implementation, the offshore wind power foundation provided in this application includes multiple first injection components, each of which is spaced apart circumferentially along the foundation body, wherein the circumferential spacing angle of each first injection component is 30°-60°; and multiple second injection components, each of which is spaced apart circumferentially along the foundation body, wherein the circumferential spacing angle of each second injection component is 30°-60°.

[0044] Wind energy, as a clean and renewable energy source, is being widely used globally. Offshore wind turbines are one of the important ways to utilize wind energy, and they typically consist of offshore wind turbine foundations. Offshore wind turbine foundations are built at sea; when sea ice forms, the ice can impact the foundations, causing ice-induced vibrations that can compromise the safety and stability of both the foundations and the offshore wind turbines.

[0045] In related technologies, upright flexible foundation technology and anti-ice cone technology are commonly used. Upright flexible foundations mainly rely on their stiffness and strength to directly resist sea ice impacts, but cannot avoid the impact of ice-induced vibrations on structural stability. Anti-ice cone technology reduces the direct impact of sea ice on wind turbine foundations by installing anti-ice cones near the sea surface; however, the presence of anti-ice cones increases the waterline area of ​​the wind turbine foundation, leading to a significant increase in wave loads. Therefore, a new type of offshore wind turbine foundation is urgently needed.

[0046] In view of this, the offshore wind power foundation and offshore wind turbine provided in this application are capable of breaking up ice layers to reduce the adverse effects of ice-induced vibration on the stability of the foundation structure and to avoid increasing wave loads.

[0047] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0048] See Figures 1 to 4 This application provides an offshore wind power foundation, which may include a foundation body 10 and an ice-breaking device 20. The foundation body 10 has a predetermined height and has a first mounting portion (not shown) and a second mounting portion 11 opposite each other in its height direction X. The first mounting portion is used to connect to a generator set, and the second mounting portion 11 is used to connect to the seabed. The generator set may include components such as a tower, nacelle, generator, and rotor. The ice-breaking device 20 is disposed on the outer periphery of the foundation body 10 and includes a first spray assembly 100 and a second spray assembly 200. The first spray assembly 100 and the second spray assembly 200 are spaced apart along the height direction X. Both the first spray assembly 100 and the second spray assembly 200 are used to spray fluid onto the ice layer 50. The angle of inclination of the fluid spray direction of at least one of the first spray assembly 100 and the second spray assembly 200 relative to the height direction X is adjustable.

[0049] In practical implementation, the foundation body 10 constitutes the supporting core of the offshore wind power foundation. The foundation body 10 has a predetermined height to ensure that the generator set can be stably placed above the sea surface while maintaining an appropriate distance from the seabed. Along the vertical direction X of the foundation body 10, a first mounting part and a second mounting part 11 are provided. The first mounting part is located above the sea surface for a secure connection with the generator set, ensuring safe and efficient power generation. The second mounting part 11 is located below the sea surface for connection with the seabed, firmly installing the foundation body 10 on the seabed so that the foundation body 10 can withstand the impact of natural forces such as wind, waves, and tides.

[0050] Optionally, the first mounting part and the generator set can be fixedly connected by means of bolts, flanges, prestressed tendon riveting, welding, etc. The second mounting part 11 can be fixedly installed on the seabed by piling or drilling, and this application does not impose any restrictions on this.

[0051] It is understood that by setting up the ice-breaking device 20, the ice layer 50 on the sea surface can be broken. The ice-breaking device 20 may include a first jet assembly 100 and a second jet assembly 200 arranged at intervals along the height direction X. The first jet assembly 100 can be set above the sea surface, for example, on the working platform where the base body 10 is installed, and the second jet assembly 200 can be set below the sea surface, or it can be set according to the usage requirements. The jetting ends of the first jet assembly 100 and the second jet assembly 200 are both set towards the ice layer 50. The first jet assembly 100 and the second jet assembly 200 are used to jet high-pressure fluid onto the ice layer 50 to break up or weaken the ice layer 50. For example, the fluid may be seawater or other media that can effectively melt the ice layer 50.

[0052] Optionally, the fluids sprayed by the first spray assembly 100 and the second spray assembly 200 can be the same medium or different media. Depending on the severity of the ice condition, the first spray assembly 100 and the second spray assembly 200 can be used individually or in combination.

[0053] By setting up the ice breaking device 20, the ice layer 50 can be broken up, preventing sea ice from directly scouring the foundation body 10, reducing the sea ice load, and reducing the adverse effects of ice-induced vibration on the structural stability of the foundation body 10. At the same time, the ice breaking device 20 will not increase the area of ​​the foundation body 10 above the water surface, thus avoiding an increase in wave load.

[0054] Furthermore, at least one of the first spray assembly 100 and the second spray assembly 200 can be configured to have an adjustable fluid spray direction, meaning that its tilt angle relative to the height direction X of the base body 10 can be adjusted according to actual needs. This configuration allows for the removal of ice and snow from the base body 10 itself (e.g., the base body 10's work platform, mooring ladder, guardrails, and other auxiliary components), thus eliminating the need for manual de-icing and facilitating maintenance work, thereby improving maintenance efficiency.

[0055] See Figure 1 In some embodiments, along the height direction X, the first spray assembly 100 is disposed on the side of the second spray assembly 200 away from the second mounting portion 11. The first spray assembly 100 includes a pressure spray member 110, a first conveying member 120 and a pumping and pressurizing member 130 disposed on the first conveying member 120. One end of the first conveying member 120 is connected to the pressure spray member 110, and the other end is used to connect to seawater. At least a portion of the pressure spray member 110 has rotational freedom relative to the base body 10.

[0056] The pressure water spray component 110 is configured with a rotational degree of freedom, allowing it to adjust its spray direction as needed. When spraying ice layer 50, the spraying end of the pressure water spray component 110 can be directed towards the ice layer 50, and the spraying direction can be adjusted as required to break up or weaken the ice layer 50, thereby reducing the sea ice load. When ice forms on the working platform, mooring ladder, guardrails, and other auxiliary components of the base body 10, the spraying direction of the pressure water spray component 110 can be adjusted to achieve the de-icing function of the base body 10 itself, thereby improving operation and maintenance efficiency. For example, the pressure water spray component 110 can be a high-pressure water gun.

[0057] Optionally, when installing the pressure water spray component 110, the horizontal distance between the pressure water spray component 110 and the outer peripheral surface of the base body 10 can be 0.5m-1.5m to ensure the ice-breaking effect of the pressure water spray component 110.

[0058] In some embodiments, the first conveying member 120 may be a connecting pipe between the pressure spray member 110 and seawater. The connecting pipe may be made of a material with good sealing and corrosion resistance to ensure that the water flow does not leak or become damaged during the conveying process.

[0059] The pumping and pressurizing component 130 provides power to the first jet assembly 100. Optionally, the pumping and pressurizing component 130 may include a pumping pump and a pressurizing pump. In specific implementation, starting the pumping pump allows seawater to be pumped through the first conveying component 120 and delivered to the pressure jet component 110. The pressurizing pump drives the pressure jet component 110 to spray high-pressure water. Different pressures can be set according to the specific conditions of the ice layer 50 to break up the ice layer 50, effectively reducing the sea ice load and mitigating the adverse effects of ice-induced vibration on the structural stability of the foundation body 10. Furthermore, by pumping seawater to supply water to the first jet assembly 100, abundant seawater resources can be utilized without the need for additional fluid resources, thus reducing costs.

[0060] See Figure 1 In some embodiments, the pressure water spray component 110 includes a first connecting section 111, a second connecting section 112, and a rotating component 113. The rotating component 113 is rotatably connected between the first connecting section 111 and the second connecting section 112. The first connecting section 111 is in communication with the first conveying component 120, and the second connecting section 112 is used to spray seawater.

[0061] The rotating component 113 provides a rotatable connection between the first connecting section 111 and the second connecting section 112, allowing the second connecting section 112 to adjust its spray direction as needed, thereby achieving precise spraying to different areas or angles. This configuration enhances the spraying flexibility and practicality of the pressure water spray component 110.

[0062] The first connecting section 111 is connected to the first conveying component 120 to ensure smooth water flow. The first connecting section 111 can be a metal pipe or a plastic pipe to meet the transmission requirements.

[0063] The second connecting section 112 serves as a component for spraying water. It can be made of metal or plastic and can employ a conical nozzle or an adjustable nozzle to meet the requirements of different spray angles and intensities. By designing the nozzle structure, the second connecting section 112 can generate a uniform and stable water flow, ensuring the reliability of the spraying effect.

[0064] The rotating component 113 is used to connect the first connecting segment 111 and the second connecting segment 112. The rotating component 113 can adopt a spherical nozzle structure, which includes a fixed base and a spherical joint rotatably connected to the fixed base. The fixed base and the spherical joint have through holes to allow communication between the first connecting segment 111 and the second connecting segment 112. The fixed base can be used to connect with the first connecting segment 111, and the spherical joint can be used to connect with the second connecting segment 112 to ensure that the second connecting segment 112 can rotate smoothly and stably relative to the first connecting segment 111. Simultaneously, the rotating component 113 can also be equipped with a locking mechanism to fix the spray direction of the second connecting segment 112.

[0065] Of course, in some embodiments, the rotating member 113 may include a universal joint or other structure. The first connecting section 111 is made of rigid metal, and the second connecting section 112 may be made of flexible plastic. The second connecting section 112 is connected to the first connecting section 111. Part of the rotating member 113 is connected to the first connecting section 111, and the other part of the rotating member 113 is connected to the second connecting section 112. By making the two universally connected parts of the rotating member rotate relative to each other, the second connecting section 112 can be driven to rotate relative to the first connecting section 111.

[0066] See Figure 1 In some embodiments, the second jet assembly 200 includes a pressure jet member 210, a second conveyor member 220, and a suction pressurizing member 230 disposed on the second conveyor member 220. One end of the second conveyor member 220 is connected to the pressure jet member 210, and the other end is used to communicate with gas.

[0067] The pressure jet 210 is connected to the suction and pressurization component 230 via the second conveyor 220, together forming a jet system that enables precise control and efficient jetting of the gas. The suction and pressurization component 230 extracts and pressurizes the gas from the external environment, and then transmits it to the pressure jet 210 via the second conveyor 220 for jetting.

[0068] In practice, the pressure jet component 210 can be configured as a nozzle structure, and the material of the nozzle structure can be selected as a wear-resistant and corrosion-resistant material to ensure its long-term stable operation.

[0069] Understandably, the second conveyor 220 is used to connect the pressure jet component 210 and the vacuum pressurization component 230. The second conveyor 220 can adopt a pipeline conveying method to meet transmission requirements. One end of the second conveyor 220 can be connected to gas, and the other end can be connected to air, thereby reducing the operating cost of the second jet assembly 200.

[0070] The suction and pressurization component 230 provides power to the second jet assembly 200. The suction and pressurization component 230 may include a suction pump and a pressurization pump. Specifically, the second jet assembly 200 can be positioned below the sea surface. Activating the suction pump allows gas to be drawn through the second conveyor 220 and delivered to the pressure jet assembly 210. The pressurization pump drives the pressure jet assembly 210 to eject high-pressure gas. This high-pressure gas forms high-pressure bubbles in the seawater. These high-pressure bubbles explode upon contact with the lower surface of the ice layer 50, creating an explosive impact that breaks the sea ice or weakens its strength. Different pressures can be set according to the specific conditions of the ice layer 50 to achieve ice layer breakage, effectively reducing sea ice load and mitigating the adverse effects of ice-induced vibration on the structural stability of the foundation body 10.

[0071] In some embodiments, the second injection assembly 200 further includes an anti-corrosion layer (not shown) disposed on the pressure jet member 210; and / or, the second injection assembly 200 further includes a check valve (not shown) disposed on the jet end of the pressure jet member 210.

[0072] Understandably, by applying an anti-corrosion layer, the pressure jet component 210 can be provided with additional protection, extending the service life of the second jet assembly 200. By coating the surface of the pressure jet component 210 with an anti-corrosion layer, the corrosive effects of seawater can be effectively reduced, maintaining the integrity and performance of the second jet assembly 200. For example, the anti-corrosion layer can be made of stainless steel. Alternatively, corrosion protection can also be achieved through impressed current cathodic protection (ICCP). ICCP is a technique that utilizes the principle of electrochemical corrosion, applying a cathodic current to the protected structure via an external DC power supply to prevent corrosion.

[0073] It should be noted that the check valve enhances the safety and reliability of the second injection assembly 200. The check valve can be installed at the jet end of the pressure jet element 210. The check valve prevents seawater from flowing into the pressure jet element 210, thus improving the operational safety of the pressure jet element 210. Optionally, the check valve can include a spring-loaded check valve or a solenoid check valve, which can be selected and configured according to the specific requirements of the second injection assembly 200.

[0074] By incorporating an anti-corrosion layer and a check valve, the durability and safety of the second injection assembly 200 are enhanced. The anti-corrosion layer reduces maintenance costs due to corrosion, while the check valve prevents potential risks caused by seawater ingress.

[0075] See Figure 1In some embodiments, the base body 10 has a cavity 12 and an opening communicating with the cavity 12; a first injection assembly 100 is partially disposed in the cavity 12 and partially protrudes from the base body 10 through the opening; and / or, a second injection assembly 200 is partially disposed in the cavity 12 and partially protrudes from the base body 10 through the opening.

[0076] With this configuration, the first conveyor 120 can protrude from the base body 10 through an opening to communicate with seawater, and the second conveyor 220 can also protrude from the base body 10 through an opening to connect with gas, thereby realizing the spraying function of the first spray assembly 100 and the second spray assembly 200. The connection between the first conveyor 120 and the opening can be sealed with a sealing element, and similarly, the connection between the second conveyor 220 and the opening can also be sealed with a sealing element.

[0077] See Figure 4 In some embodiments, the system further includes a controller 30 and a detector 40. The detector 40 is disposed on the base body 10 and is communicatively connected to the controller 30. The detector 40 includes a sea ice detector and a motion detector. The sea ice detector is used to detect the sea ice coverage rate in the wind farm area. The wind farm area can be understood as the sea area within a radius of 10 km centered on the base body 10, and the sea ice coverage rate can be understood as the coverage rate of the ice layer 50 in the wind farm area. The motion detector is used to detect the vibration of the base body 10. The controller 30 is communicatively connected to the ice and snow breaking device 20 and is used to control the start and stop of the ice and snow breaking device 20.

[0078] The detector 40 is installed on the base body 10 and can collect information about the wind farm area and the base body 10 in real time and accurately. Specifically, the detector 40 may include a sea ice detector and a motion detector. The sea ice detector may be a video detector 40 or a satellite scanner, which can accurately detect the sea ice coverage in the wind farm area, providing timely and accurate data support for the operation of the ice and snow breaking device 20. The motion detector may be an accelerometer sensor, used to detect the vibration of the base body 10.

[0079] The controller 30 is responsible for receiving and processing information from the detector 40 and issuing commands based on the information. The controller 30 is communicatively connected to the ice-breaking device 20 and can precisely control the start and stop of the ice-breaking device 20 as needed. When the sea ice detector detects that the sea ice coverage in the wind farm area exceeds a preset threshold, such as exceeding 70%, the controller 30 will immediately activate the ice-breaking device 20 to break the ice layer 50, ensuring the normal operation of the wind farm. Simultaneously, if the mobile detector detects abnormal vibration of the foundation 10, the controller 30 will also respond quickly, activating the ice-breaking device 20 to break the ice layer 50, preventing the ice layer 50 from impacting and damaging the foundation 10.

[0080] In addition, the sea ice detector can also detect the icing condition of the auxiliary components of the base body 10 (such as the icing condition of the work platform, mooring ladder, and guardrail). Before going out to sea for maintenance, the staff can use the sea ice detector to check the icing condition of the auxiliary components. When icing is detected on the auxiliary components of the base body 10, the controller 30 can activate the first spray assembly 100 and adjust the pressure water spray component 110 to a suitable angle to de-ice the auxiliary components, thereby facilitating the staff to carry out maintenance work on the base body 10, ensuring maintenance safety, and improving maintenance efficiency.

[0081] See Figure 2 and Figure 3 In some embodiments, a plurality of first spraying components 100 are provided, and each first spraying component 100 is arranged at intervals along the circumferential Y direction of the base body 10, wherein the interval angle between the first spraying components 100 arranged at intervals along the circumferential Y direction is 30°-60°; a plurality of second spraying components 200 are provided, and each second spraying component 200 is arranged at intervals along the circumferential Y direction of the base body 10, wherein the interval angle between the second spraying components 200 arranged at intervals along the circumferential Y direction is 30°-60°.

[0082] In practice, the interval angle between two adjacent first spraying components 100 can be set in the range of 30° to 60°, including the two extreme values ​​of 30° and 60°, and can be selected as 45°. This setting not only ensures the uniformity and comprehensiveness of ice and snow breaking, but also improves the working efficiency of the first spraying component 100, so that the ice layer 50 around the base body 10 can be broken in a shorter time.

[0083] To further enhance the ice-breaking capability of the ice-breaking device 20, multiple second spraying components 200 can be configured, also spaced apart along the circumferential Y direction of the base body 10. The interval angle between two adjacent second spraying components 200 can be set within the range of 30° to 60°, including the two extreme values ​​of 30° and 60°, with 45° being an option. This configuration allows the second spraying components 200 to more comprehensively cover the area surrounding the base body 10, ensuring the continuity and stability of the ice-breaking process. Through the coordinated operation of the first spraying component 100 and the second spraying component 200, the ice-breaking device 20 can more efficiently and quickly break the ice layer 50 around the base body 10, thereby ensuring the normal operation and safe and stable operation of the wind farm.

[0084] Optionally, each first injection assembly 100 and each second injection assembly 200 may be aligned or staggered in the circumferential Y direction of the base body 10, and this application does not impose any restrictions on this.

[0085] In some embodiments, the distance between at least one of the first spray assembly 100 and the second spray assembly 200 and the first mounting portion is adjustable along the height direction X.

[0086] In practice, the distances between the first spray assembly 100 and the first mounting part, as well as the distances between the second spray assembly 200 and the first mounting part, can be adjusted. This improves the flexibility and adaptability of the ice and snow removal device 20. By adjusting the distances between the first spray assembly 100, the second spray assembly 200, and the first mounting part, the spray force and spray range can be optimized.

[0087] Based on the above embodiments, this application provides an offshore wind turbine generator set, including a generator set and the above-mentioned offshore wind power foundation, wherein the generator set is installed in the first mounting part of the offshore wind power foundation.

[0088] The offshore wind power foundation has been described in detail in the above embodiments and will not be repeated here.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
