As shown in fig. 1, the floating offshore wind power platform with the wave energy device at least comprises:
the floating type offshore wind power platform is a floating type wind power single-column structure 100, and comprises a thin single-column section 110, a transition section 120 and a thick single-column section 130 which are sequentially and coaxially connected in the vertical direction, wherein the top end of the thin single-column section 110 is connected with an offshore wind power device;
the wave energy power generation system comprises a driving piston rod 310 and a power generation assembly, wherein the power generation assembly is fixed in the floating wind power single-column structure 100, one end of the driving piston rod 310 is connected with the power generation assembly, and the other end is connected with the wave energy absorption plate 200;
the wave energy absorbing plates 200, at least three wave energy device energy absorbing plates 200 are uniformly arranged at the same height of the floating wind power single-column structure 100 in the circumferential direction through the driving piston rods 310, and the water plane of the floating wind power single-column structure 100 is in the height range of the wave energy absorbing plates 200;
a mooring system 400 fixed to the bottom of the thick single-column section 130 to limit the range of motion of the floating offshore wind platform;
the wave energy absorbing plates 200 are in one-to-one correspondence with the driving piston rods 310, and are combined with the power generation assembly to form the wave energy device.
Specifically, the floating wind power single-column structure 100 comprises a thin single-column section 110, a transition section 120 and a thick single-column section 130 which are sequentially and coaxially connected in the vertical direction, so that the whole gravity center of the single-column structure can be downwards moved through the thick single-column section 130 arranged below, a similar tumbler structure is formed, the stability is improved, and the overturning risk is reduced. When waves propagate to the wave energy absorbing plate 200 under the environment condition suitable for the water depth, a part of wave energy is born by the wave energy absorbing plate 200 and pushes the driving piston rod 310 to perform extrusion or stretching motion relative to the power generation assembly, the power generation assembly absorbs mechanical energy transmitted by the driving piston rod 310 and converts the mechanical energy into electric energy, power generation by utilizing the wave energy is realized, a multi-energy complementary system of 'offshore wind energy and wave energy' is formed, the wave energy is developed while wind power generation is performed, and the utilization rate of offshore renewable energy sources is improved.
Two kinds of compound motions can occur to the wave energy absorbing plate 200 under the effect of wave, on the one hand the wave energy absorbing plate 200 extrudes inwards or stretches outwards along the horizontal direction and drives the piston rod 310 so as to enable the power generation assembly to generate power, and meanwhile, the wave energy power generation system also outputs additional rigidity and damping on degrees of freedom such as swaying and pitching, so that the motion amplitude in the horizontal direction is reduced, the requirement on a mooring system is reduced, and therefore the overall manufacturing cost is reduced.
On the other hand, the water plane is located within the height range of the wave energy absorbing plate 200, and when the integral platform encounters extreme sea conditions, the top section of the wave energy absorbing plate 200 cannot be immersed in water, and the bottom cannot cross the water surface no matter what the integral platform moves. Since the water surface is at a particular height of the wave energy absorber plate 200, the waves will cause the wave energy absorber plate 200 to torque about the drive piston rod 310. The wave energy absorbing plate 200 has a water plane and is far away from the whole gravity center, so that a certain restoring moment can be provided, the design difficulty of the whole stability of the single-column platform structure is reduced, and the whole steel consumption is reduced to reduce the system cost. If the wave energy absorber plate 200 is floated or fully immersed in the water, the restoring moment provided by the wave energy absorber plate is lost, and the change of the water plane area is caused, so that the non-linear change of the motion performance is generated, and the change of the water plane area directly influences the change of the motion performance due to the direct relation between the water plane area and the motion response performance such as heave.
As shown in fig. 3, the general symbol is used to indicate that the wave power generation system provides damping and rigidity in the horizontal direction for the whole platform, and the displacement response of the whole platform in the horizontal direction is reduced, which can be understood as increasing the friction force. The restoring moment is mainly the concept of the stability of the whole system, namely, the stability of the whole system cannot be turned over in stormy waves, and the larger the water plane area of the whole structure is, the better the stability is; the larger the static moment of the waterline surface to the axis of the floating center is, the better the stability is. Because the wave energy absorbing plate 200 has a water plane and is far from the center of buoyancy, the wave energy absorbing plate has better stability performance compared with a traditional single-column floating fan.
By way of example, the wave energy absorber plate 200 is secured to the thin single column section 110 by driving the piston rod 310. In general, in order to increase the stability of the floating offshore wind platform, the overall center of gravity is set to be relatively low, and the thick single-column section 130 is immersed in the sea, the water plane is located in the thin single-column section 110, so that the wave energy absorbing plate 200 is fixed on the thin single-column section 110 by driving the piston rod 310, as shown in fig. 1-2. Of course, the height of the wave energy absorbing plate 200 is increased, or the thick single-column section 130 has enough weight to realize the water plane thereon, and the wave energy absorbing plate 200 can be fixed on the thick single-column section 130 by driving the piston rod 310, as shown in fig. 3, and the arrangement is specifically performed according to practical requirements.
By way of example, the profile depth of the thick single column section 130 can be adjusted according to the site of application and the capacity of the offshore wind plant, and the water plane area of the wave energy absorber plate 200 can be adjusted. Typically, the floating wind power single-column structure 100 needs to be disposed in a sea area with a water depth of at least 155-200 m, providing enough underwater space to dispose the thick single-column section 130 to lower the center of gravity, and providing the floating wind power single-column structure 100 with sufficient stability. When placed in a relatively shallow sea area, it is desirable to relatively shorten the vertical length of the thick single column section 130. While this inevitably results in a heavy center moving upwards, in order to continue to ensure that the floating wind power single-column structure 100 has sufficient stability, the cross-sectional area of the wave energy absorbing plate 200 may be increased simultaneously to provide sufficient water plane area to maintain stability, i.e. the thickness and/or length of the wave energy absorbing plate 200 needs to be increased. In addition, when the capacity of the offshore wind turbine is large, a thick single column section 130 with a sufficient length needs to be arranged in the underwater space to lower the gravity center so as to ensure stability, and when the capacity of the offshore wind turbine is small, a thick single column section 130 with a relatively short length needs to be arranged in the underwater space. Therefore, the depth of the thick single-column section 130 can be adjusted according to the applied site and the capacity of the offshore wind turbine, and the water plane area of the wave energy absorbing plate 200 can be adjusted, so that the applicable sea area range and the applicable capacity range of the offshore wind turbine of the floating wind power single-column structure 100 can be increased, and the applicability is improved. The length and width adjustment may be performed by arranging a combination of a telescopic motor and a telescopic rod inside the thick single column section 130 and the wave energy absorbing plate 200, or may be performed by other manners, which are not limited herein.
The power generation assembly includes, as an example, a hydraulic power generation assembly or a pneumatic power generation assembly. The rigidity of the wave energy device power generation system can be improved by reducing the flow rate of liquid or gas in the pipeline corresponding to the hydraulic power generation assembly or the pneumatic power generation assembly so as to improve the stability of the platform; the power generation efficiency of the wave energy device power generation system can be improved by improving the flow rate of liquid or gas in the pipeline corresponding to the hydraulic power generation assembly or the pneumatic power generation assembly. Therefore, the rigidity of the wave energy power generation system can be adjusted by adjusting the flow rate of liquid or gas in the corresponding pipeline of the hydraulic power generation assembly or the pneumatic power generation assembly so as to cooperatively improve the power generation efficiency and the platform stability under different sea conditions.
As an example, a control system (not shown) is further included, and the control system is disposed in the thin single column section 110 or the transition section 120, and is electrically connected with the floating wind power single column structure 100, the wave energy device power generation system and the wave energy absorbing plate 200 for controlling and automatically adjusting.
In an embodiment, as shown in fig. 4, the power generation assembly is a hydraulic power generation assembly, and includes a hydraulic cylinder 321, a first electromagnetic proportional valve 324, a second electromagnetic proportional valve 325, a third electromagnetic proportional valve 326, a fourth electromagnetic proportional valve 327, a hydraulic motor 328, and a generator 329, wherein a piston of a piston rod 310 is driven in the hydraulic cylinder 321 to perform extrusion stretching motion, and the piston rod passes through the hydraulic cylinder 321 and the floating wind power single-column structure 100 and is fixedly connected with the wave energy absorbing plate 200. For the piston hydraulic cylinder 321 both ends bottom all is provided with liquid oil interface 322, and liquid oil interface 322 passes through pipeline 323 and hydraulic motor 328 formation liquid way, and hydraulic motor 328 is connected with generator 329 transmission in order to drive generator 329 and generate electricity. The first electromagnetic proportional valve 324 is communicated with the second electromagnetic proportional valve 325 in series, and the third electromagnetic proportional valve 326 is communicated with the fourth electromagnetic proportional valve 327 in series and then communicated with the liquid path in parallel, wherein the parallel end of the first electromagnetic proportional valve 324 and the third electromagnetic proportional valve 326 is communicated with the inlet of the hydraulic motor 328 through a pipeline 323, and the parallel end of the second electromagnetic proportional valve 325 and the fourth electromagnetic proportional valve 327 is communicated with the outlet of the hydraulic motor 328 through a pipeline 323. One liquid-oil interface 322 is communicated between the first electromagnetic proportional valve 324 and the second electromagnetic proportional valve 325, the other liquid-oil interface 322 is communicated between the third electromagnetic proportional valve 326 and the fourth electromagnetic proportional valve 327, and the first electromagnetic proportional valve 324, the second electromagnetic proportional valve 325, the third electromagnetic proportional valve 326 and the fourth electromagnetic proportional valve 327 are electrically connected with the control system.
When the piston rod 310 is driven to perform stretching motion in the hydraulic cylinder 321, the control system controls the second electromagnetic proportional valve and the third electromagnetic proportional valve to be closed, and the liquid in the hydraulic cylinder 321 flows through the hydraulic motor 328 through the first electromagnetic proportional valve 324 and flows back to the hydraulic cylinder 321 through the fourth electromagnetic proportional valve 327. When the piston rod 310 is driven to perform squeezing motion in the hydraulic cylinder 321, the control system controls the first electromagnetic proportional valve 324 and the fourth electromagnetic proportional valve 327 to be closed, and liquid in the hydraulic cylinder 321 flows through the hydraulic motor 328 through the third electromagnetic proportional valve 326 and flows back to the hydraulic cylinder 321 through the second electromagnetic proportional valve 325. Regardless of stretching or squeezing, liquid can flow through the hydraulic motor 328 from the same direction, so that the hydraulic motor 328 can continuously drive the generator 329 to rotate for generating electricity.
When the hydraulic system specifically works, the rigidity of the hydraulic system can be changed according to the data of the environment monitoring system, and when the environment condition is severe, the rigidity can be improved to keep the motion response amplitude of the whole system, so that the motion amplitude of the whole structure is kept stable. Preferably, the rigidity of the hydraulic system is combined with monitoring data such as sense wave height, wave direction and the like of waves, and if the sense wave height of the waves becomes high, the rigidity of the hydraulic system can be improved, and the horizontal displacement of the platform can be reduced; due to the presence of multiple wave energy absorber plates 200, the stiffness of the main wave direction corresponding hydraulic system can be increased according to the wave direction monitoring result without increasing all the stiffness. The control system receives sense wave height and wave direction monitoring signals of waves, and controls the main wave direction to correspond to the opening degrees of a first electromagnetic proportional valve 324, a second electromagnetic proportional valve 325, a third electromagnetic proportional valve 326 and a fourth electromagnetic proportional valve 327 in the power generation system of the wave energy device so as to adjust rigidity.
