Description

[0001] The present invention relates to the field of offshore new energy technology, and in particular to a floating foundation and a floating new energy device having the same. Background Art

[0002] Offshore new energy (including offshore wind power and offshore photovoltaics) is an important part of my country's renewable energy power generation. Vigorously developing offshore new energy is of great significance to my country's transformation to clean energy. my country has strong endowments of deep-sea wind power and photovoltaic resources and great potential for development. For the development of deep-water offshore wind power and photovoltaics, the use of floating foundation structures is more economical. The design and application of floating foundations mainly revolve around renewable energy power generation projects such as offshore wind power and offshore photovoltaics, especially for the development of deep or ultra-deep waters. The design concept of the floating foundation is to allow the supporting structure to float with the waves instead of being fixed to the seabed. This design can overcome the high cost and complexity of seabed construction in deepwater areas and avoid the ecological damage that may be caused by seabed construction.

[0003] In the related art, since the floating foundation is affected by waves on the sea surface, it will swing to a certain extent, causing the wind power or photovoltaic generator set installed on the floating foundation to tilt and swing periodically, which has an adverse effect on the reliable and safe operation of the generator set. In order to improve the wave stability of the floating foundation and reduce the amplitude of the floating foundation's swaying movement with waves, it is often achieved by increasing the structural size of the floating foundation, increasing the displacement, or designing a more stable anchor system.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 4 As shown, an embodiment of the present invention provides a floating foundation, which includes an underwater buoy 10, an above-water buoy 30 and at least two waist columns 20, wherein the at least two waist columns 20 are arranged in the circumferential direction of the underwater buoy 10, the lower ends of the at least two waist columns 20 are connected to the underwater buoy 10, the upper ends of the at least two waist columns 20 are connected to the above-water buoy 30, a wave-piercing space 40 is formed between the above-water buoy 30 and the underwater buoy 10, the total draft cross-sectional area of ​​the at least two waist columns 20 is smaller than the total draft cross-sectional area of ​​the above-water buoy 30, and the total draft cross-sectional area of ​​the at least two waist columns 20 is smaller than the total draft cross-sectional area of ​​the underwater buoy 10.

[0032] The floating foundation provided by this embodiment is applied, and the floating foundation includes an underwater buoy 10, an above-water buoy 30, and at least two waist columns 20. Under normal working conditions, the underwater buoy 10 is completely immersed below the waterline, and the underwater buoy 10 provides the main buoyancy and ballast force. The lower end of the waist column 20 is immersed below the waterline, and the remaining part of the waist column 20 and the above-water buoy 30 are located above the water surface, so that a wave-piercing space 40 is formed between the above-water buoy 30 and the underwater buoy 10, and the above-water buoy 30 does not bear the main buoyancy. In extreme sea conditions, if the floating foundation undergoes excessive heaving motion, the above-water buoy 30 can be quickly immersed in water to provide additional buoyancy to help the floating foundation return to its normal position. Since the above-water buoy 30 only provides spare buoyancy, does not provide overall support for the entire floating foundation, and does not bear the role of supporting the overall structural strength, the above-water buoy 30 can be designed to be light and thin, thereby reducing material consumption and saving costs.

[0033] Among them, since the total draft cross-sectional area of ​​at least two waist columns 20 is smaller than the total draft cross-sectional area of ​​the above-water floating body 30, the total draft cross-sectional area of ​​at least two waist columns 20 is smaller than the total draft cross-sectional area of ​​the underwater floating body 10. Under normal working conditions, the waist columns 20 are penetrated through the water surface, and the waves in the wave-piercing space 40 act on the waist columns 20. By reducing the total draft cross-sectional area of ​​at least two waist columns 20, the force of the shallow wave flow on the sea surface (i.e., the waves in the wave-piercing space 40) on the waist columns 20 can be reduced, and the disturbance effect of the shallow wave flow on the floating foundation is reduced, thereby increasing the stability of the floating foundation under normal working conditions (i.e., shallow waves).

[0034] Specifically, when the floating foundation undergoes an overall heaving motion at sea, if the heaving amplitude is too large, due to the effect of inertia, the floating foundation together with the generator set supported thereon will sink toward the seabed. When the sinking amplitude exceeds the height of the waist column 20, the floating body 30 on the water begins to sink into the water and generate buoyancy. Moreover, the greater the submergence amplitude of the floating body 30 on the water, the greater the buoyancy provided by the floating body 30 on the water. The additional buoyancy increased by the floating body 30 on the water is transmitted to the underwater floating body 10 through the waist column 20. At this time, the buoyancy of the entire floating foundation is already much greater than the gravity, thereby pulling the entire floating foundation back to the sea surface.

[0035] like Figure 1 and Figure 3 As shown, the floating body 30 on the water includes at least two water-surface monomers 31, and the upper ends of at least two waist columns 20 are connected to at least two water-surface monomers 31 in a one-to-one correspondence, and the draft cross-sectional area of ​​each waist column 20 is smaller than the draft cross-sectional area of ​​each water-surface monomer 31. The waist column 20 is the transition part between the underwater and the above-water part of the floating foundation under normal working conditions. Since the draft cross-sectional area of ​​each waist column 20 is smaller than the draft cross-sectional area of ​​each water-surface monomer 31, the disturbance of waves to the floating foundation can be reduced. This design greatly reduces the wave force on the waist column 20 near the waterline, because the wave force is proportional to the underwater cross-sectional area of ​​the object. Therefore, even under the action of shallow waves, the waist column 20 has a small disturbance to the overall structure, thereby improving the stability of the floating foundation in a wave environment.

[0036] like Figure 1 and Figure 3As shown, the underwater floating body 10 includes at least two underwater monomers 11, and the lower ends of at least two waist columns 20 are connected to the at least two underwater monomers 11 in a one-to-one correspondence. The draft cross-sectional area of ​​each waist column 20 is smaller than the draft cross-sectional area of ​​each underwater monomer 11. The waist column 20 is the transition part between the underwater and the above-water part of the floating foundation under normal working conditions. Since the draft cross-sectional area of ​​each waist column 20 is smaller than the draft cross-sectional area of ​​each underwater monomer 11, the disturbance of waves to the floating foundation can be reduced. This design greatly reduces the wave force on the waist column 20 near the waterline, because the wave force is proportional to the underwater cross-sectional area of ​​the object. Therefore, even under the action of shallow waves, the waist column 20 has a small disturbance to the overall structure, thereby improving the stability of the floating foundation in a wave environment.

[0037] In addition, the waist column 20 is used to connect the underwater monomer 11 and the above-water monomer 31, forming a unique "thick at both ends and thin in the middle" shape.

[0038] like Figure 1 As shown, the underwater buoy 10 further comprises a buoy frame 12, and at least two underwater monomers 11 are arranged on the upper surface of the buoy frame 12 at intervals along the circumference of the buoy frame 12. The buoy frame 12 acts as a heave plate to weaken the effect of the heave motion of the underwater buoy 10 in the water.

[0039] like Figure 1 and Figure 3 As shown, the buoy frame 12 includes at least two connected sections 121, which are arranged along the circumferential direction of the underwater buoy 10, and at least two underwater monomers 11 are arranged one by one on the at least two connecting sections 121. The buoy frame 12 acts as a heave plate to weaken the effect of the up and down heave movement of the underwater buoy 10 in the water.

[0040] like Figure 1 As shown, the buoy frame 12 adopts a radial structure, the connecting section 121 extends along the radial direction of the buoy frame 12, at least two underwater monomers 11 are arranged one by one at the first ends of at least two connecting sections 121, and the second ends of at least two connecting sections 121 are connected. The buoy frame 12 acts as a heave plate to weaken the effect of the up and down heave movement of the underwater buoy 10 in the water.

[0041] like Figure 3 As shown, the buoy frame 12 adopts a polygonal structure, the extension direction of the connecting section 121 is set at an angle with the radial direction of the buoy frame 12, the first end of one of the two adjacent connecting sections 121 is connected to the second end of the other connecting section 121, and the underwater monomer 11 is arranged at the connection of the two adjacent connecting sections 121. The buoy frame 12 acts as a heave plate to weaken the effect of the up and down heave movement of the underwater buoy 10 in the water.

[0042] In the present application, the buoy frame 12 includes three connecting sections 121, and the underwater buoy 10 includes three underwater monomers 11 arranged in a herringbone shape.

[0043] like Figure 2 As shown, the floating foundation further includes at least two first reinforcement structures 50, which are arranged one by one at the connection between the underwater floating body 10 and the at least two waist columns 20, and the first reinforcement structure 50 includes at least two first reinforcement ribs 51 arranged along the circumferential direction of the waist column 20, and the first reinforcement ribs 51 extend along the radial direction of the waist column 20. The first reinforcement structure 50 enhances the connection strength between the waist column 20 and the underwater floating body 10, ensuring the structural rigidity and stability in a wave environment.

[0044] In this embodiment, the floating foundation further includes at least two second reinforcement structures, which are arranged one by one at the connection between the floating body 30 and the at least two waist columns 20, and the second reinforcement structure includes at least two second reinforcement ribs arranged along the circumferential direction of the waist column 20, and the second reinforcement ribs extend along the radial direction of the waist column 20. The second reinforcement structure enhances the connection strength between the waist column 20 and the floating body 30, ensuring the structural rigidity and stability in the wave environment.

[0045] In this embodiment, the connecting section 121 has a first regulating chamber and a first regulating port connected to the first regulating chamber, the underwater monomer 11 has a second regulating chamber and a second regulating port connected to the second regulating chamber, the floating foundation also includes a sensor, a first regulating pump, a first switch valve, a second regulating pump, a second switch valve and a controller, the sensor is arranged on the floating foundation to detect the inclination degree of the floating foundation, the first regulating pump and the first switch valve are arranged at the first regulating port, the second regulating pump and the second switch valve are arranged at the second regulating port, and the controller is respectively connected to the sensor, the first regulating pump, the first switch valve, the second regulating pump and the second switch valve signal to control the first regulating pump, the first switch valve, the second regulating pump and the second switch valve to work according to the detection result of the sensor. When the sensor detects that the floating foundation is experiencing heaving motion or tilting, the controller controls the first regulating pump, the first switch valve, the second regulating pump and the second switch valve to operate, and dynamically fills or discharges ballast water into or out of the first regulating chamber and the second regulating chamber to adjust the distribution of the ballast water, adjust the center of gravity position and buoyancy distribution of the underwater floating body 10, affect the dynamic behavior of the underwater floating body 10 in the water, and increase the stability of the floating foundation.

[0046] In this embodiment, the cross section of the connecting section 121 is a rectangular cross section. Under the premise that the volume of the connecting section 121 is constant, the connecting section 121 has a smaller underwater cross-sectional area, reduces wave resistance, and ensures that the connecting section 121 can provide sufficient buoyancy.

[0047] In this embodiment, the cross-sectional area ratio of the floating body 30 and the waist column 20 is between 4 and 9.

[0048] Specifically, the cross-sectional area ratio of the floating body 30 and the waist column 20 can be 4, 5, 6, 7, 8, 9, and any value in between.

[0049] In this embodiment, the cross-sectional area ratio of the underwater unit 11 and the waist column 20 is between 4 and 20.

[0050] Specifically, the cross-sectional area ratio of the underwater monomer 11 and the waist column 20 can be 4, 12, 16, 20, or any value in between.

[0051] In this embodiment, the height ratio between the floating body 30 and the waist column 20 is between 0.5 and 1.

[0052] Specifically, the height ratio of the floating body 30 and the waist column 20 may be 0.5, 0.6, 0.7, 0.8, 0.9, 1, or any value between 0.5 and 1.

[0053] like Figure 5 As shown, another embodiment of the present invention provides a floating new energy device, the floating new energy device includes a power generation device 60 and a floating foundation, the power generation device is arranged on the floating foundation, and the floating foundation is the floating foundation provided above. Using the floating new energy device provided by this embodiment, under normal working conditions, the underwater floating body 10 is completely immersed below the waterline, the underwater floating body 10 provides the main buoyancy and ballast force, the lower end of the waist column 20 is immersed below the waterline, and the rest of the waist column 20 and the floating body 30 are located above the water surface, so that a wave-piercing space 40 is formed between the floating body 30 and the underwater floating body 10, and the floating body 30 does not bear the main buoyancy. Under extreme sea conditions, if the floating foundation undergoes excessive vertical movement, the floating body 30 can be quickly immersed in water to provide additional buoyancy to help the floating foundation return to its normal position. Since the floating body 30 only provides backup buoyancy, it does not provide overall support for the entire floating foundation and does not bear the role of supporting the overall structural strength. Therefore, the floating body 30 can be designed to be lightweight, thereby reducing material consumption and saving construction costs.

[0054] It should be noted that when the power generation device adopts wind power generation, the floating foundation preferably has three groups of water monomers 31, underwater monomers 11 and waist columns 20 to reduce the structural cost and ensure the stability effect to achieve the best balance. When the power generation device adopts photovoltaic power generation, multiple groups of water monomers 31, underwater monomers 11 and waist columns 20 are combined according to actual needs. Common ones include three groups of water monomers 31, underwater monomers 11 and waist columns 20, four groups of water monomers 31, underwater monomers 11 and waist columns 20, and six groups of water monomers 31, underwater monomers 11 and waist columns 20.

Therefore, they cannot be understood as limiting the scope of protection of the present invention.
