DETAILED DESCRIPTION

[0047] The core of this application is to provide a wind power floating platform to improve the construction convenience of offshore floating wind power foundations.

[0048] Another core of the present application is to provide a wind power floating platform construction method for the above-mentioned wind power floating platform.

[0049] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0050] Offshore floating wind turbine foundations primarily include column-type and semi-submersible foundations. The center of gravity of a column-type floating wind turbine foundation must be significantly lower than its buoyancy. When the turbine tilts due to horizontal forces, the restoring torque is generated primarily by the shift in the center of gravity. Semi-submersible floating wind turbine foundations rely primarily on widely spaced side columns along the turbine perimeter. When the turbine tilts due to horizontal forces, the restoring torque is generated primarily by the changes in the buoyancy of the surrounding columns.

[0051] With the trend toward larger wind turbines, the use of column-based floating wind turbine foundations requires greater draft depth to meet operational stability requirements. This limits their applicability. Furthermore, their long lengths make their manufacture and installation more challenging. Semi-submersible floating wind turbine foundations require greater spacing between the side columns and require more steel, resulting in poor economic efficiency and higher costs for offshore floating wind turbines.

[0052] For this reason, Figure 1 As shown, an embodiment of the present application discloses a floating wind power platform, comprising a wind turbine platform 10, a floating body 20, and a first support column 30, wherein the first support column 30 comprises a ballast section and a floating chamber section connected to the ballast section. By integrating the ballast system onto the first support column 30, precise control of the ascent and descent of the floating wind power platform 100 can be achieved through a water pump. Furthermore, by prefabricating the wind turbine platform 10, the floating body 20, the ballast section, the floating chamber section, and the connector 40 into an integral unit, rapid assembly of the wind turbine platform 10, the floating body 20, and the first support column 30 can be achieved at the installation site of the floating wind power platform 100, thereby improving the construction convenience of the offshore floating wind power foundation, simplifying the installation process, and reducing costs.

[0053] The following will be combined Figures 1 to 6 The wind power floating platform disclosed in the embodiment of the present application is specifically explained and illustrated.

[0054] Among them, the wind turbine platform 10, the floating body 20, the ballast section, the floating bunker section and the connecting piece 40 can all be prefabricated and formed into an integral piece, so that the wind turbine platform 10, the floating body 20 and the first supporting column 30 can be quickly assembled at the installation site of the wind power floating platform 100, thereby improving the construction convenience of the offshore floating wind power foundation, simplifying the installation process and reducing costs.

[0055] like Figure 1 and Figure 4As shown, multiple first support columns 30 may be used, i.e., three, four, or more first support columns 30 may be used. Each first support column 30 is spaced apart around the wind turbine platform 10 and connected between the wind turbine platform 10 and the buoyancy member 20 to form a floating wind turbine platform. The ballast section and the buoyancy section of the first support columns 30 may be connected using fasteners such as bolts, or may be welded to form the first support columns 30. At the same time, the ballast section of the first support column 30 can be detachably connected to the float member 20 by fasteners such as bolts, or can be connected and fixed by welding. At the same time, the floating section of the first support column 30 can be connected to the wind turbine platform 10 through the connecting member 40 by fasteners such as bolts, or can be connected and fixed by welding, so that the two ends of the first support column 30 are respectively connected to the wind turbine platform 10 and the float member 20 to form a wind power floating platform, and the wind turbine 200 can be installed on the wind turbine platform 10, and the float member 20 provides buoyancy for the wind power floating platform to ensure that the wind turbine 200 operates stably at sea level.

[0056] The ballast section of the first support column 30 may have a first cavity, and the floating section of the first support column 30 may have a second cavity, and a water pump is provided in the second cavity. When the horizontal force of the wind turbine causes tilting, water can be transported to the first cavity or discharged from the first cavity by the water pump to achieve the floating and diving of the wind power floating platform 100, thereby generating a restoring torque to ensure the stable operation of the wind turbine 200 at sea level. It should be noted that the first cavity and the second cavity can be separated by a partition to prevent water in the first cavity from entering the second cavity, thereby damaging the electronic components in the second cavity, and the water pump can be a diesel water pump.

[0057] In some embodiments, as Figure 1 and Figure 4 As shown, the first support columns 30 can be circular columns to reduce wave resistance, reduce the scouring effect of seawater on the first support columns 30, and ensure the stability of the wind turbine floating platform 100. Three first support columns 30 can be used, and the three first support columns 30 are evenly spaced around the wind turbine platform 10 to form a triangular distribution. At the same time, adjacent first support columns 30 are connected by a connector 40, and the connector 40 is connected to the wind turbine platform 10, thereby ensuring that the force generated by the wind turbine 200 can be transmitted from the connector 40 to the float 20 through the first support columns 30, and balanced with the buoyancy generated by the float 20.

[0058] In some embodiments, as Figure 5As shown, the connecting member 40 can adopt a rectangular structure, and the two ends of the connecting member 40 can form symmetrically arranged inclined surfaces to ensure that there is a larger contact area between the two ends of the connecting member 40 and the first support column 30, thereby ensuring the reliability of the connection between the connecting member 40 and the first support column 30.

[0059] In some embodiments, as Figure 2 As shown, the wind turbine platform 10 may include a support platform 11 and a connection platform 12 connected to the support platform 11. The cross-sectional shape of the support platform 11 may be circular, and the cross-sectional shape of the connection platform 12 may be rectangular. At the same time, the connection platforms 12 may be multiple and evenly spaced along the circumference of the support platform 11. Figure 1 As shown, wind turbine 200 can be installed on support platform 11. One end of connecting platform 12 is connected to support platform 11, and the other end of connecting platform 12 can be connected to the middle position of connecting member 40 near the side of support platform 11, so that wind turbine platform 10, connecting member 40 and first support column 30 are arranged in the same plane. That is, the upper surface of wind turbine platform 10, the upper surface of connecting member 40 and the top surface of first support column 30 are on the same plane. It should be noted that the cross-sectional shape of support platform 11 can also adopt other geometric shapes such as rectangle and triangle, which is not limited here.

[0060] In order to ensure the overall stability of the wind power floating platform 100, Figure 1 As shown, the wind power floating platform 100 may further include a second support column 50, and the second support column 50 may be multiple, that is, the second support column 50 may be three, four or more, and each second support column 50 is distributed around the wind turbine platform 10 at intervals, and the second support column 50 is connected between the connecting member 40 and the floating member 20 to improve the overall stability and strength of the wind power floating platform 100.

[0061] In some embodiments, as Figure 6 As shown, the second support columns 50 can be circular columns to reduce wave resistance, reduce the scouring effect of seawater on the first support columns 30, and ensure the stability of the wind turbine floating platform 100. The diameter of the second support columns 50 can be smaller than the diameter of the first support columns 30. Three first support columns 30 can be used, and the three second support columns 50 are respectively connected to corresponding positions on the connection platform 12. That is, one end of the second support column 50 is connected to the middle position of the connecting member 40 on the side close to the floating member 20, and the other end of the second support column 50 is connected to the floating member 20. This allows part of the force generated by the wind turbine 200 to be transmitted from the connecting member 40 to the floating member 20 through the second support columns 50, thereby reducing the force applied to the first support columns 30, ensuring the overall stability and strength of the wind turbine floating platform 100, and improving the service life of the wind turbine floating platform 100.

[0062] In some embodiments, the second support column 50 may be provided with a weight-reducing cavity to reduce the weight of the second support column 50 , thereby improving the overall stability and strength of the wind turbine floating platform 100 while ensuring that the float 20 can provide a large buoyancy, so that the wind turbine 200 can be stably installed on the wind turbine platform 10 . The weight-reducing cavity may be provided along the height direction of the second support column 50 , and one or more weight-reducing cavities may be used to reduce the weight of the second support column 50 . The specific number and size of the weight-reducing cavities may be determined according to actual conditions.

[0063] In some embodiments, as Figure 1 and Figure 3 As shown, the float member 20 can adopt a triangular ring structure to reduce the weight of the float member 20, thereby enabling the float member 20 to provide greater buoyancy. The first support column 30 can be connected to the corner of the float member 20. The float member 20 has a contact surface 21 and a connection surface 22 disposed opposite each other. The contact surface 21 can contact the water. The first support column 30 is connected to the connection surface 22. The first support column 30 and the connection surface 22 are arranged at a predetermined angle. The predetermined angle can be 90°, 120°, 135°, 150°, etc. It should be noted that the float member 20 can also adopt a circular ring structure or other polygonal ring structure.

[0064] like Figure 3 As shown, the float member 20 has a loading cavity to which a load can be applied, so that the float member 20 can float up and dive down by applying a load to the loading cavity.

[0065] In some embodiments, a heavy object such as a concrete block can be placed in the loading chamber to apply a fixed load to the float member 20, thereby enabling the float member 20 to provide fixed buoyancy support. Alternatively, a diesel water pump can be placed in the loading chamber to deliver water to the loading chamber of the float member 20, thereby applying a dynamic load to the float member 20 and adjusting the buoyancy of the float member 20 according to actual needs.

[0066] In some embodiments, as Figure 1 、 Figure 3 and Figure 4As shown, the end of the first support column 30 connected to the connector 40 is positioned away from the center of the connection surface 22, while the end of the first support column 30 connected to the connection surface 22 is positioned closer to the center of the connection surface 22. This means that the preset angle is greater than 90°, resulting in a structural system in which the cross-sectional area of ​​the wind turbine floating platform 100 gradually decreases from top to bottom. This ensures that the wind turbine floating platform 100 is less likely to tilt, thereby improving the stability of the wind turbine floating platform 100. Furthermore, both ends of the first support column 30 have elliptical cross-sections to ensure that the upper surface of the wind turbine platform 10, the upper surface of the connector 40, and the top surface of the first support column 30 are on the same plane. This also allows the connection surface 22 of the first support column 30 to the float member 20 to have a larger connection area, thereby ensuring the reliability of the connection between the first support column 30 and the float member 20.

[0067] In some embodiments, the wind turbine platform 10 may have a hollow structure, and the connector 40 may include a connection cavity. The connection cavity may communicate with the wind turbine platform 10 and a second cavity, respectively, to form a power supply channel through which a cable can be passed. The two ends of the cable may be connected to the output of the wind turbine 200 and the water pump, respectively, thereby directly providing power to the water pump using the electricity generated by the wind turbine 200. Furthermore, the electricity generated by the wind turbine 200 may be transmitted to submarine power transmission equipment via a dynamic cable.

[0068] In some embodiments, the floating bin section may include an upper floating bin section and a lower floating bin section. The upper floating bin section and the lower floating bin section may be detachably connected by fasteners such as bolts, or may be fixedly connected by welding. At the same time, the upper floating bin section may be connected to the connector 40, and the lower floating bin section may be connected between the upper floating bin section and the ballast section. The upper floating bin section has an upper cavity, and the lower floating bin section has a lower cavity, so that a second cavity can be formed by the upper cavity and the lower cavity, and the water pump can be located in the lower cavity. At the same time, the cable can pass through the upper cavity and be connected to the water pump in the lower cavity. The upper cavity of the upper floating bin section can serve as an isolation chamber to prevent water from flowing from the first cavity of the ballast section through the lower cavity into the power supply channel and causing a safety accident.

[0069] It should be noted that in the above embodiment, the wind turbine platform 10, the floating body 20, the first support column 30 and the second support column 50 are all made of metal materials to ensure greater strength, so that the wind power floating platform 100 can bear the torque transmitted by the wind turbine 200, thereby improving the stability and strength of the wind power floating platform 100.

[0070] To ensure the stability of the floating wind turbine platform 100 in the water, it may also include a mooring assembly. This assembly may include an anchor foundation and an anchor chain. The anchor foundation may be made of carbon steel or stainless steel, but it may also be made of concrete or prestressed concrete. The anchor foundation may be fixed to the seabed, while the ends of the anchor chain may be connected to the anchor foundation and the buoy 20, respectively. This anchor chain allows the floating wind turbine platform 100 to be towed, thereby enhancing its scour resistance.

[0071] In some embodiments, the contact surface 21 of the floating body 20 may be provided with a connecting lug, and the connecting lug may be provided with a connecting hole, so that one end of the anchor chain can be connected to the mooring foundation, and the other end of the anchor chain can be connected to the connecting hole of the connecting lug via an anchor. Multiple anchor chains may be used, that is, three, four, or more anchor chains may be used, each evenly spaced below the floating body 20. The connecting lugs can be adapted to the anchor chains, that is, each anchor chain corresponds to a connecting lug, to ensure the reliability of the connection between the floating body 20 and the anchor chains. The use of multiple anchor chains can also improve the anti-scour performance of the wind power floating platform 100 in multiple directions.

[0072] In some embodiments, the anchor chain may include a floating section, a reinforcement section, and a loading device. The reinforcement section is disposed at both ends of the floating section, and the loading device is disposed on the floating section. The loading device applies a load to the floating section, thereby changing the shape of the anchor chain, ensuring the stability of the anchor chain force transmission, and thereby improving the anti-scour performance of the floating wind turbine platform 100. It should be noted that the floating section of the anchor chain can be made of materials such as nylon, ultra-high molecular weight polyethylene, polyoxymethylene, polyester, polyetheretherketone, or polyurethane, and the reinforcement section can be made of metal materials such as carbon steel, stainless steel, alloy steel, or high-strength steel.

[0073] In some embodiments, the loading device may include a buoy, and loading the buoy enables the floating section of the anchor chain to rise and dive. The buoy may be equipped with an inlet control valve to control the amount of water entering, and a water outlet control valve to control the amount of water leaving. This allows the load applied to the buoy to be controlled by controlling the amount of water entering and leaving the buoy. Of course, a water pump may also be provided within the buoy to deliver water to the buoy, thereby enabling loading of the buoy, but this is not limited herein.

[0074] The floating wind turbine platform 100 disclosed in the embodiments of the present application prefabricates the wind turbine platform 10, the buoyancy member 20, the ballast section, the floating chamber section, and the connector 40 into an integral unit. This allows for rapid assembly of the wind turbine platform 10, the buoyancy member 20, and the first support column 30 at the installation site of the floating wind turbine platform 100. Simultaneously, a water pump located within the second chamber of the floating chamber section of the first support column 30 pumps water into the first chamber of the ballast section, enabling the floating wind turbine platform 100 to float and dive.

[0075] The wind power floating platform 100 disclosed in the embodiment of the present application integrates the ballast system on the first support column 30, and can achieve precise control of the floating and diving of the wind power floating platform 100 through a water pump. At the same time, by prefabricating the wind turbine platform 10, the floating body 20, the ballast section, the floating bunker section and the connecting piece 40 into an integral body, it can achieve rapid assembly between the wind turbine platform 10, the floating body 20 and the first support column 30 at the installation site of the wind power floating platform 100, thereby improving the construction convenience of the offshore floating wind power foundation, simplifying the installation process and reducing costs.

[0076] like Figure 7 As shown, the embodiment of the present application also discloses a method for constructing a wind power floating platform. With respect to the wind power floating platform disclosed in the above embodiment, it has all the technical effects of the above wind power floating platform, which will not be described in detail herein. The method for constructing a wind power floating platform may include step S100 of prefabricating platform components, step S200 of assembling the first supporting column, step S300 of assembling the platform foundation, and step S400 of assembling the floating platform. Figures 1 to 9 The wind power floating platform construction method disclosed in the embodiment of the present application is specifically explained and illustrated.

[0079] Step S200, assembling the first supporting column;

[0080] The ballast section and the floating section are connected to form a first support column 30. The ballast section and the floating section can be detachably connected and fixed with fasteners such as bolts, or can be connected together by welding to form the first support column 30.

[0081] Step S300, assembling the platform foundation;

[0082] The ballast section of the first support column 30 is connected to the floating body 20 to form a platform foundation. Figure 1 and Figure 3 As shown, the end face of the ballast section of the first support column 30 can be detachably connected to the connection surface 22 of the float member 20 using fasteners such as bolts, or the end face of the ballast section of the first support column 30 can be connected to the connection surface 22 of the float member 20 by welding to form a platform foundation.

[0083] Step S400, assembling a floating platform;

[0084] The platform foundation, wind turbine platform 10, and connector 40 are transported by barge to the assembly area for assembly to form the floating platform. The end faces of the floating section of the first support column 30 of the platform foundation are connected to the ends of the connector 40 using bolts or other fasteners or welding. Furthermore, the connection platform 12 of the wind turbine platform 10 is fixed to the middle of the side of the connector 40 using bolts or other fasteners or welding to complete the assembly of the floating platform.

[0085] The platform components may also include an anchor foundation and an anchor chain, that is, the anchor foundation and the anchor chain may also be prefabricated in a factory.
