[0002] With the growing demand for renewable energy worldwide, offshore wind power generation has become an important direction for energy transformation due to its abundant wind energy resources and non-land space occupation. With the development of deep sea areas, floating wind power platforms have emerged. Such platforms are supported by buoyancy and anchored to the seabed, and can operate stably in deep water, becoming the core technology for deep sea wind power development.

DETAILED DESCRIPTION

[0019] The present application will be further described below in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related application, and are not a limitation on the application. The described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application.

[0020] In order to solve the problem of low energy utilization rate of the existing floating wind power platform, the structure of the floating wind power platform is specifically introduced in combination with the drawings: As shown in Figures 1 to 3 The present application provides a floating wind power platform 10, which comprises a semi-submersible floating platform 200, a first mooring system 310, a concrete block 400, a second mooring system 320 and a roll damping power generation device 500. The main body of the roll damping power generation device 500 is arranged on the semi-submersible floating platform 200. The first power end 501 of the roll damping power generation device 500 is connected with the concrete block 400 through the first mooring system 310. The second power end 502 of the roll damping power generation device 500 is connected with the seabed through the second mooring system 320, so as to capture wave energy or tidal energy.

[0021] When deep sea wind power development is carried out, the floating wind power platform 10 provided by the scheme can be used, the anti-rolling power generation device 500 is arranged on the semi-submersible floating platform 200, the shaking of the sea surface can generate wave energy or tidal energy, under the action of the wave energy or the tidal energy, the concrete block 400 can shake relative to the semi-submersible floating platform 200, the shaking of the concrete block 400 relative to the semi-submersible floating platform 200 can drive the first power end 501 to swing through the first mooring system 310, drive the second power end 502 to swing through the second mooring system 320, and drive the anti-rolling power generation device 500 to generate power. Since the floating wind power platform 10 of the application is used, the wave energy or the tidal energy can be captured to be converted into electric energy, so that the energy utilization way of the floating wind power platform 10 is expanded, and the energy utilization is more sufficient.

[0022] It should be explained that the function of the semi-submersible floating platform 200 is to provide overall support and ensure that the floating wind power platform 10 floats on the sea surface.

[0023] As shown in Figure 1 , the semi-submersible floating platform 200 can include pontoons 201, heave plates 202, platform wind turbine bases 203, pontoon connecting beams 204, and wind turbine base connecting beams 205. The pontoons 201 are located on the heave plates 202, the pontoon connecting beams 204 connect two adjacent pontoons 201, the first end of the wind turbine base connecting beam 205 is connected to the pontoon 201, and the second end of the wind turbine base connecting beam 205 is connected to the platform wind turbine base 203.

[0024] Generally, the number of pontoons 201 corresponds to the number of heave plates 202, the number of pontoon connecting beams 204, and the number of wind turbine base connecting beams 205 one by one, and the symmetry of the overall layout needs to be ensured to cope with complex sea conditions and ensure the structural stability of the floating wind power platform 10. The number of pontoons 201 can be 3, 4, 5, etc., and is symmetrically distributed.

[0025] Referring to Figure 2 , taking the number of pontoons 201 in the embodiment as an example, the three pontoons 201 are distributed in a regular triangle, three heave plates 202 are arranged at the bottom of each pontoon 201, three pontoon connecting beams 204 are used to fixedly connect two pontoons 201, and three wind turbine base connecting beams 205 are used to fixedly connect the three pontoons 201 and the platform wind turbine base 203, so as to ensure the stability and firmness of the platform wind turbine base 203.

[0026] It should be noted that the structure of the pontoon 201 is hollow, which provides buoyancy for the whole floating wind power platform 10. The heave plate 202 is single-layer or multi-layer, arranged at the bottom of the pontoon 201, and used to suppress the heave (up and down) movement of the pontoon 201. When the pontoon 201 moves up and down with the sea water, the heave plate 202 forces the surrounding sea water to flow around the edge thereof, generating vortex or friction, consuming wave energy, thereby reducing the heave displacement of the pontoon 201, and making the floating wind power platform 10 more stable.

[0027] The heave plate 202 described above can be horizontally arranged at the bottom of the pontoon 201 (the axis of the heave plate 202 is parallel to the axis of the pontoon), or can be obliquely arranged at the bottom of the pontoon 201 (the axis of the heave plate 202 is oblique to the axis of the pontoon). When the heave plate 202 is obliquely arranged, the obliquely arranged heave plate 202 generates resistance to suppress the rotational movement of the pontoon 201 in addition to suppressing the heave movement of the pontoon 201, thereby enhancing the stability of the equipment. Thus, the inclination angle of the heave plate 202 can be flexibly set according to the characteristics of the wave main direction and frequency of the working sea area, so as to achieve optimal stability.

[0028] When the number of the pontoon 201 includes multiple, the heave plate 202 of a part of the pontoon 201 can be obliquely arranged, and the heave plate 202 of another part of the pontoon 201 can be horizontally arranged; the heave plate 202 of all the pontoon 201 can be obliquely arranged; or the heave plate 202 of all the pontoon 201 can be horizontally arranged.

[0029] In addition, the heave plate 202 under each pontoon 201 can also be provided in an inverted V-shaped structure. The inverted V-shaped structure refers to a wing surface with two sides inclined, which is made by bending a single plate or welding two plates at a certain angle. When the heave plate 202 in the inverted V-shaped structure moves, it pushes more water to participate in the movement, increases the inertia of the system, and suppresses the oscillation.

[0030] The above mainly describes the arrangement of the heave plate 202. In some examples of the present application, in order to further improve the stability of the floating wind power platform 10, a third mooring system 330 is further arranged at the bottom of the pontoon 201, and the third mooring system 330 is connected to the seabed. When the heave plate 202 arranged on the pontoon 201 is subjected to the action of waves and moves upward, the third mooring system 330 generates a reverse force, which reduces the heave amplitude, thereby further enhancing the stability of the semi-submersible floating platform 200.

[0031] The buoy connecting beam 204 and / or the wind turbine base connecting beam 205 can be solid or hollow. When the buoy connecting beam 204 and the wind turbine base connecting beam 205 are hollow cylindrical structures, while reducing the weight of the entire floating wind turbine platform 10, cables can be arranged inside them, reducing cable exposure. For example, this can reduce aging and corrosion, thereby extending the service life of the cables. When the buoy connecting beam 204 and the wind turbine base connecting beam 205 are solid structures, the connection strength between the buoy connecting beam 204 and the wind turbine base connecting beam 205 can be increased, thereby improving the impact / slap resistance of the entire floating wind turbine platform 10.

[0032] The structure of the semi-submersible floating platform 200 has been introduced above. Next, the structure of the anti-rolling power generation device 500 will be described in detail.

[0033] The function of the anti-rollover power generation device 500 is to capture wave or tidal energy, convert it into electrical energy, and provide damping torque to reduce the sway of the floating wind turbine platform 10 and improve its stability. The anti-rollover power generation device 500 is installed on the buoy connecting beam 204 and / or the wind turbine base connecting beam 205. The operating principle of the anti-rollover power generation device 500 is described in detail below, using the example of the device installed on the buoy connecting beam 204 in this embodiment.

[0034] The anti-rollover power generation device 500 may include a power assembly and a power generation assembly. The power assembly is used to convert external sway, such as sway of the first mooring system 310 and / or the second mooring system 320, into rotational motion of the power assembly. The power generation assembly is in transmission connection with the power assembly to convert the rotational motion of the power assembly into electrical energy. For example, the power assembly may include a first power end 501, a second power end 502, and a transmission shaft 503. The first power end 501 and the second power end 502 are both in transmission connection with the transmission shaft 503. The transmission shaft 503 is in transmission connection with the power generation assembly via bearings and gears. The first power end 501 swings under the action of the first mooring system 310, and the second power end 502 swings under the action of the second mooring system 320. The swinging of the first power end 501 and the second power end 502 drives the transmission shaft 503 to rotate, which is then transmitted to the power generation assembly.

[0035] Because the first power end 501 and the second power end 502 swing under the action of the mooring system, to facilitate understanding of this solution, we can define the swing plane of the first power end 501 and the swing plane of the second power end 502. To improve the ability of the anti-sway power generation device 500 to capture sway, the swing plane of the first power end 501 and the swing plane of the second power end 502 are parallel to each other. Because these two swing planes are parallel, the first mooring system 310 and the second mooring system 320 swing in the same longitudinal direction under their action, reducing energy loss caused by inconsistent swing directions.

[0036] In addition, the first end of the first mooring system 310 is movably connected with the concrete block 400, and the second end of the first mooring system 310 is movably connected with the first power end 501; the first end of the second mooring system 320 is fixedly connected with the seabed, and the second end of the second mooring system 320 is movably connected with the second power end 502. The so-called movable connection means that the first mooring system 310 has a certain degree of activity relative to the concrete block 400 while being connected, for example, the first mooring system 310 can have four degrees of freedom relative to the concrete block 400, including front, back, left and right, of course, this is only an example, and does not mean that the first mooring system 310 has only four degrees of freedom relative to the concrete block 400. Similarly, the second mooring system 320 has a certain degree of activity relative to the second power end 502.

[0037] When the wave motion causes the concrete block 400 to move relative to the anti-rolling power generation device 500, the concrete block 400 drives the first power end 501 to make a certain angle of oscillation movement with the transmission shaft 503 as the axis, and the oscillation trajectory of the first power end 501 is called the oscillation surface of the first power end 501. At the same time, due to the oscillation of the first power end 501, the second power end 502 makes an opposite angle of oscillation, and after being subjected to the reaction force of the second mooring system 320, it swings back, and thus reciprocates, the second power end 502 makes a certain angle of oscillation movement with the transmission shaft 503 as the axis, and the oscillation trajectory of the second power end 502 is called the oscillation surface of the second power end 502.

[0038] Further, the oscillation surface of the first power end 501 and the oscillation surface of the second power end 502 coincide. Under the action of the first mooring system 310 and the second mooring system 320, the directions of the two oscillations are completely consistent, and energy loss due to inconsistent oscillation directions can be avoided. The line connecting the first power end 501 and the second power end 502 is perpendicular to the transmission shaft 503, in this case, the oscillation surface of the first power end 501 and the oscillation surface of the second power end 502 are in the same plane; in some embodiments, the line connecting the first power end 501 and the second power end 502 is not perpendicular to the transmission shaft 503, in this case, the oscillation surface of the first power end 501 and the oscillation surface of the second power end 502 are not in the same plane, but are parallel to each other.

[0039] Referring to Figure 3 In this embodiment, since the anti-rolling power generation device 500 is arranged on the pontoon connecting beam 204, the above-mentioned transmission shaft 503 is perpendicular to the oscillation surfaces of the two power ends, therefore, the oscillation surfaces of the two power ends are perpendicular to the axis of the pontoon connecting beam 204. In some embodiments, the anti-rolling power generation device 500 is arranged on the fan base connecting beam 205, then the oscillation surfaces of the two power ends are perpendicular to the axis of the fan base connecting beam 205.

[0040] Due to the swing movement of the first power end 501 and the second power end 502, the wave energy or tidal energy is converted into mechanical energy, which drives the transmission shaft 503 to move axially, thereby driving the power generation assembly to rotate axially and converting the mechanical energy into electrical energy.

[0041] The power generation assembly receives the rotation torque transmitted by the power assembly to generate electricity, and the power generation assembly can include a generator capable of generating electricity. In addition, the power generation assembly of the present application can also provide directional damping for the power assembly. Specifically, the power generation assembly can include a frequency converter, which adjusts the excitation frequency to adjust the speed of the engine, thereby adjusting the damping torque of the power assembly to cope with the swing movement of the first power end 501 and the second power end 502 under different sea surface conditions, while generating electricity, it also enhances the stability of the floating wind power platform 10.

[0042] Taking the power generation assembly in the embodiment as an example, when the sea surface is relatively stable, the wave energy is small, and the swing amplitude of the first power end 501 and the second power end 502 is small, at this time the speed of the generator is low, and the damping torque is small, and the small swing can meet the power generation; when the sea surface fluctuates obviously, the swing is violent, the wave energy is large, and the swing amplitude of the first power end 501 and the second power end 502 is relatively large, at this time the generator automatically adjusts the speed to be larger, generates a larger damping torque, meets the power generation, at the same time, ensures the stability of the power generation of the power generation assembly, and reduces the swing of the floating wind power platform 10, further improves the stability of the operation.

[0043] Further, the power assembly can also include a controller which can adjust the excitation frequency of the frequency converter according to the pre-stored data. Specifically, the power assembly can also include a sensor which can detect the wind value of the sea surface; the controller pre-stores the corresponding relationship between the wind value and the excitation frequency, and the controller can obtain the target excitation frequency of the frequency converter according to the corresponding relationship between the wind value and the excitation frequency, and control the frequency converter to operate to the target excitation frequency. The structure of the anti-roll power generation device 500 is introduced above, and the structure of the wind turbine generator 100 is introduced below.

[0044] The wind turbine generator 100 is the core of the floating wind power platform 10, which functions to convert the wind energy on the sea surface into electrical energy and store it in the power grid system. Referring to Figure 1 , the wind turbine generator 100 includes a wind turbine 110 and a wind turbine rod 120, the first end of the wind turbine rod 120 is in transmission connection with the wind turbine 110, and the second end of the wind turbine rod 120 is in fixed connection with the platform wind turbine base 203, and the platform wind turbine base 203 is connected to the power grid system. The structure of the wind turbine rod 120 is a hollow cylindrical structure, and the inside of the wind turbine rod 120 can be arranged with a power transmission cable to transmit the electricity generated by the wind turbine 110 to the power grid system.

[0045] In the embodiment, the wind turbine pole 120 is a single column, which not only connects the wind turbine 110 and the platform wind turbine base 203, but also bears the load of the floating wind power platform 10 in various complex sea environments. In some embodiments, diagonal braces are arranged at the connection between the wind turbine pole 120 and the platform wind turbine base 203 to enhance the overall stability of the wind turbine pole 120.

[0046] The number of blades of the wind turbine 110 can be greater than or equal to one. The more the number of blades, the higher the wind energy capture efficiency, but the marginal benefit decreases, for example, the wind energy capture efficiency of 4 blades is only about 5% higher than that of 3 blades; the more the number of blades, the overall load and cost of the wind turbine 110 are significantly increased. In the embodiment, the wind turbine 110 has 3 blades, which has a high wind energy capture efficiency, moderate blade load and cost, and stable operation.

[0047] In some embodiments, the axis of the wind turbine generator 100 coincides with the axis of the semi-submersible floating platform 200, which can ensure the overall stable operation of the floating wind power platform 10.

[0048] The above is a specific introduction to the overall structure of the wind turbine generator 100.

[0049] In addition, it is emphasized that the axis of the concrete block 400 coincides with the axis of the semi-submersible floating platform 200. The concrete block 400 functions to suppress the vibration of the semi-submersible floating platform 200 and coordinate the stability of the floating wind power platform 10. Since the concrete block 400 is directly connected to the semi-submersible floating platform 200, ensuring that the axis of the concrete block 400 coincides with the axis of the semi-submersible floating platform 200 can make the floating wind power platform 10 run smoothly in both static and dynamic conditions. In the embodiment, the number of concrete blocks 400 is 1, and when installed, it is only necessary to ensure that the axis of the single concrete block 400 coincides with the axis of the semi-submersible floating platform 200; in some embodiments, the number of concrete blocks 400 is multiple, and when installed, it is necessary to ensure that the overall axis of the multiple concrete blocks 400 coincides with the axis of the semi-submersible floating platform 200.
