[0034] Offshore wind power generation platforms include fixed and floating types. Floating wind power platforms float on the sea surface through their own floating structure and are fixed in a predetermined position using a mooring system. Floating wind power platforms can adapt to deeper sea environments.

[0035] Existing floating wind turbine platforms need to be built in shipyards first. After construction, the floating wind turbine platforms need to be transported as a whole to the dock and rolled onto a large semi-submersible vessel before they can be launched. Due to the large size and weight of the floating wind turbine platforms, the overall transportation is quite difficult.

[0036] The floating wind power platform provided in this application embodiment, by dividing the floating wind power platform into a floating installation base, multiple steel columns, and multiple connecting supports, can be transported separately to the sea during construction and completed at sea, reducing transportation difficulties. The embodiments of this application will be further described below with reference to the accompanying drawings.

[0038] Combination Figure 1-4 As shown, this application embodiment provides a floating wind power platform, including:

[0039] The floating body mounting base 100 includes at least three transition columns 110, at least three concrete columns 120, and at least three pontoon supports 130. The transition columns 110 are connected to the corresponding concrete columns 120, and the two ends of the pontoon supports 130 are respectively connected to two adjacent concrete columns 120.

[0040] At least three steel reinforcement columns 200, which are detachably connected to the corresponding transition columns 110.

[0041] At least three connecting brackets 300, with each end of the connecting bracket 300 being detachably connected to two adjacent steel columns 200.

[0042] The floating body mounting base 100, steel column 200 and connecting bracket 300 can be manufactured in different factories and transported to the dock for installation by appropriate means of transportation after manufacturing.

[0043] The floating body mounting base 100 consists of three transition columns 110, three concrete columns 120, and three pontoon supports 130. The three transition columns 110 are evenly distributed, and the lower end of each transition column 110 is firmly connected to the corresponding concrete column 120 by welding, ensuring that the connection strength between them is sufficient to withstand various loads subsequently transmitted.

[0044] The pontoon support 130 is made of ultra-lightweight high-strength concrete. Its two ends are connected to two adjacent concrete columns 120 to form a closed ring structure, which makes the entire floating body mounting base 100 have good stability on the plane.

[0045] It is also equipped with three steel reinforcement columns 200, which provide a higher support structure for the entire wind power platform, facilitating the subsequent installation of wind power generation equipment. The lower end of each steel reinforcement column 200 is connected to the corresponding transition column 110 with high-strength bolts. This connection method facilitates installation, disassembly, and maintenance, and allows for appropriate adjustments as needed while ensuring a secure connection. The steel reinforcement columns 200 are made of special alloy steel resistant to seawater corrosion, capable of withstanding significant vertical pressure and lateral tensile forces generated by wind and waves in a marine environment, thus providing a reliable support frame for the entire wind power platform.

[0046] It is also equipped with three connecting brackets 300, which are also made of high-strength alloy steel. Each end of the connecting bracket is connected to two adjacent steel columns 200 by welding. The connecting brackets 300 are designed as truss structures. This structural form can effectively reduce its own weight while ensuring structural strength, thereby reducing the overall weight of the platform and improving the platform's floating stability on the sea surface.

[0047] At least one connecting bracket 300 has a support platform on its top for supporting wind power generation equipment.

[0048] When the two ends of the connecting bracket 300 are connected to the adjacent steel column 200, in addition to conventional welding and bolting, rubber vibration damping pads are also installed at the connection points. These pads effectively buffer the vibrations generated by the platform under wind and waves, reducing fatigue damage to the connection points caused by long-term vibration and extending the service life of the connection structure. The connecting bracket 300 adopts a box-type structure with multiple reinforcing baffles inside to enhance its bending and torsional resistance, thereby better maintaining the stability of the entire platform's upper structure.

[0049] By dividing the floating wind turbine platform into a floating installation base 100, multiple steel columns 200, and multiple connecting supports 300, they can be transported to the sea separately during construction and completed at sea, reducing transportation difficulties. Furthermore, the concrete columns 120 and steel columns 200 can be constructed simultaneously or separately in different manufacturing plants, reducing resource consumption and shortening the construction cycle.

[0050] In this embodiment, the pontoon support 130 and the concrete column 120 are integrally cast.

[0051] During the pouring process, the concrete mix ratio and pouring process parameters are strictly controlled to ensure the pouring quality. This makes the connection between the pontoon support 130 and the concrete column 120 seamless and without any weak connection points, effectively enhancing the overall stability of the floating body installation base 100.

[0052] In this embodiment, a hollow layer 400 is provided inside the transition column 110, the concrete column 120, and the floating box support 130.

[0053] These hollow layers 400 can not only reduce the overall weight of the platform to a certain extent, but also assist the floating wind power platform in floating.

[0054] The pontoon support 130 adopts a box-shaped cross section, and the internal hollow layer 400 is divided into multiple independent compartments. The independent compartment design ensures that when one compartment is damaged, the other compartments can still remain sealed, preventing the platform from sinking as a whole and improving safety.

[0055] The top of the 400-meter hollow layer is equipped with a maintenance manhole, a sealed cover, and a safety lock to facilitate personnel access for maintenance.

[0056] In this embodiment of the application, the float support 130 includes a float 131 and a support column 132. The float 131 is disposed inside the support column 132 and is located above the hollow layer 400 inside the float support 130.

[0057] The pontoon 131 is composed of multiple independent cylindrical aluminum alloy pontoons, and the support column 132 is provided with a channel to transport seawater into the pontoon 131.

[0058] In this embodiment, an installation platform 500 is also included, which is mounted on the transition column 110. The installation platform 500 is used for operators to stand on, so that operators can install the reinforcing steel column 200 and the connecting bracket 300.

[0059] In this embodiment, the outer surface of the reinforcing steel column 200 is provided with an anti-corrosion coating. The anti-corrosion coating is used to prevent seawater from corroding the body of the reinforcing steel column 200.

[0060] In this embodiment, the two ends of the pontoon support 130 are provided with inclined sides 133, and the inclined sides 133 of two adjacent pontoon supports 130 fit together. This inclined side design allows the inclined sides 133 to fit together when two adjacent pontoon supports are spliced, increasing the contact area and improving the tightness of the connection.

[0061] In this embodiment, a reinforcing connector 600 is also included. The reinforcing connector 600 is disposed at the connection between the connecting bracket 300 and the reinforcing column 200. One end of the connector is welded and fixed to the connecting bracket 300, and the other end is connected to the reinforcing column 200 by bolts.

[0062] Among them, the reinforcing connector 600 is used to reinforce the connection between the connecting bracket 300 and the steel column 200.

[0063] In this embodiment, the reinforcing connector 600 is arc-shaped. The arc radius is designed to fit the specific dimensions of the connecting bracket 300 and the reinforcing column 200, generally ranging from 0.5 to 1.5 meters, to ensure smooth stress distribution at the connection. The overall length of the connector along the connection direction is 0.8 to 1.2 meters, the width is 0.3 to 0.5 meters, and the thickness is 20 to 30 millimeters, ensuring a uniform internal structure and good mechanical properties.

[0064] In this embodiment, the hollow layer 400 of the outrigger, the hollow layer 400 of the connecting bracket 300, and the hollow layer 400 of the float bracket 130 are all filled with thermal insulation components.

[0065] The insulation materials filled in the hollow layer 400 of the outriggers, the hollow layer 400 of the connecting bracket 300, and the hollow layer 400 of the floating box bracket 130 can effectively block the conduction of external temperature, reduce the impact of low or high temperature environments on the platform interior, and make the ambient temperature of the platform interior structure and equipment relatively stable.

[0066] like Figure 5 As shown in the embodiments of this application, the method for constructing a floating wind power platform is applied to a floating wind power platform, and the method is as follows:

[0067] S100. First, connect the transition column 110 and the concrete column 120 on the ground, and then connect two adjacent concrete columns 120 through the floating box bracket 130 to obtain the floating body mounting base 100.

[0068] S200, then lower the floating body mounting base 100 into the sea and fill the inside of the pontoon support 130 with seawater, so that the floating body mounting base 100 sinks to the seabed.

[0069] S300. Finally, the steel column 200 is connected to the transition column 110, and two adjacent steel columns 200 are connected by the connecting bracket 300 to obtain the floating wind power platform.

[0070] Among them, high-strength steel is used to make the steel reinforcement column 200 and the connecting bracket 300. For the concrete column 120, the transition column 110 and the pontoon bracket 130, the three are prefabricated directly at the dock using concrete to obtain the floating body installation base 100, without the need for customization at the shipyard.

[0071] Specifically, the main body of concrete column 120 is made of concrete. The transition column 110 adopts a steel-concrete composite structure, with a steel core column inside and a concrete protective layer of a certain thickness on the outside. The two work together through shear connectors (such as studs) to enhance the overall load-bearing capacity. The support column 132 of the pontoon support 130 is made of concrete, and the pontoon 131 is located inside the support column 132.

[0072] The concrete column 120 and the pontoon support 130 are manufactured at the dock using an integrated casting process to reduce the overall transportation process. After casting, the concrete column 120 is connected to the transition column 110.

[0073] In step S100, a mold needs to be set up on the dock site first, and the floating installation base 100 is formed by integral casting through the mold. The weight of the floating installation base 100 is only half of the overall installation platform 500. Due to its light weight, most dock hoisting tools can lift the floating installation base 100 into the sea without the need for a semi-submersible vessel. Using hoisting tools saves time.

[0074] In step S200, after the floating body mounting base 100 is launched into the water, seawater is pumped in using temporary ballast equipment, so that the lower end of the floating body mounting base 100 slowly sits on the bottom until it is stable.

[0075] In step S300, the constructed steel column 200 and transition column 110 are hoisted above the floating body mounting base 100, the steel column 200 and the transition section are welded together, and the steel column 200 is connected through the connecting bracket 300 to form a floating wind power platform.

[0076] For example, after the floating wind power platform is assembled, the installation can be completed during the bottoming stage, depending on the actual needs of the wind turbine and its casing installation. Alternatively, the ballast water inside the floating wind power platform can be pumped out, allowing the main float to be in a self-floating state to complete the outfitting work and install the wind turbine and casing.

[0077] This application provides a floating wind power platform, including a floating mounting base 100. The floating mounting base 100 includes at least three transition columns 110, concrete columns 120, and pontoon supports 130. The transition columns 110 are connected to the corresponding concrete columns 120, and the two ends of the pontoon supports 130 are respectively connected to two adjacent concrete columns 120. At least three steel reinforcement columns 200 are connected to the corresponding transition columns 110. At least three connecting supports 300 are connected to two adjacent steel reinforcement columns 200 at their two ends. By dividing the floating wind power platform into a floating mounting base 100, multiple steel reinforcement columns 200, and multiple connecting supports 300, it can be transported separately to the sea during construction and constructed at sea, reducing transportation difficulties.
