[0026] 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.

[0027] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an offshore multi-energy integrated power generation device, which includes a floating platform 10, an anchor 20, a wind turbine 30, a tidal energy capture component 40 and a wave energy capture component 50. The anchor 20 includes an anchor chain 21 and a seabed anchor body 22. Both ends of the anchor chain 21 are respectively connected to the floating platform 10 and the seabed anchor body 22. The wind turbine 30 is arranged on the floating platform 10, the tidal energy capture component 40 is connected to the seabed anchor body 22, and the wave energy capture component 50 is arranged on the floating platform 10.

[0028] The offshore multi-energy integrated power generation device provided by this embodiment includes a floating platform 10, an anchor 20, a wind turbine 30, a tidal energy capture component 40, and a wave energy capture component 50. The wind turbine 30, the tidal energy capture component 40, and the wave energy capture component 50 are used to comprehensively capture offshore wind energy, wave energy, and tidal energy. Each energy resource complements each other, thereby improving the energy utilization rate and economy of the offshore multi-energy integrated power generation device. In addition, the seabed anchor 22 is connected to the seabed so that the anchor 20 provides the floating platform 10 with the necessary resistance to resist the influence of wind, waves, and tidal currents. By connecting the tidal energy capture component 40 to the seabed anchor 22, the weight and structure of the tidal energy capture component 40 can be used to increase the stability of the anchor 20 fixed point on the seabed. This layout method helps to optimize the gravity distribution of the entire system, making the floating platform 10 more stable when impacted by tidal currents. In addition, the wave energy capture component 50 is disposed on the floating platform 10 . The wave energy capture component 50 captures wave energy and at the same time reduces the shock effect of waves on the floating platform 10 , thereby further enhancing the stability of the floating platform 10 .

[0029] like Figure 1 As shown, the wave energy capturing member 50 is disposed on the side of the floating platform 10 .

[0030] like Figure 1 As shown, the offshore multi-energy integrated power generation device includes three wave energy capturing elements 50 , and the three wave energy capturing elements 50 are arranged along the circumference of the floating platform 10 .

[0031] By adopting the above layout, the gravity distribution of the three wave energy capture components 50 on the floating platform 10 remains relatively balanced, and when the offshore multi-energy integrated power generation device is subjected to waves in different directions, the risk of tilting or rotating the floating platform 10 due to unilateral force is reduced.

[0032] Furthermore, the three wave energy capture components 50 form a multi-point support structure for the floating platform 10, which can not only absorb wave energy from multiple directions, but also disperse the wave force acting on the floating platform 10 to multiple points, thereby avoiding severe shock caused by excessive force on a single point.

[0033] like Figure 1 As shown, the wave energy capture component 50 includes a linear generator and a buoy 51. The linear generator is arranged on the side of the floating platform 10. The buoy 51 is movably arranged on the floating platform 10 along the vertical direction. The buoy 51 is connected to the rotor drive of the linear generator.

[0034] Specifically, the float member 51 floats with the change of waves, and the float member 51 is drivingly connected to the mover of the linear generator, so that the linear generator converts the kinetic energy of the up and down movement of the float member 51 into electrical energy.

[0035] In the above process, the wave energy is absorbed and converted into the kinetic energy of the float member 51 , and then the kinetic energy of the float member 51 is converted into electrical energy, reducing the energy of the wave directly acting on the floating platform 10 , thereby weakening the up and down oscillation of the floating platform 10 .

[0036] In addition, when the wave energy capture component 50 is in operation, the mechanical structure (such as the hydraulic system, etc.) inside the wave energy capture component 50 will produce a damping effect. When the wave hits the floating platform 10, the damping effect can consume part of the impact energy and suppress the vibration of the floating platform 10.

[0037] like Figure 1 and Figure 2 As shown, the tidal energy capturing member 40 includes a fairing 41, a capturing member 42 and a tidal energy generator. The fairing 41 is arranged on the seabed anchor body 22. The fairing 41 has a fairing channel 43 running through both ends thereof. The capturing member is rotatably arranged in the fairing channel 43. The tidal energy generator is arranged on the seabed anchor body 22. The capturing member is connected to the rotor drive of the tidal energy generator.

[0038] Specifically, the fairing 41 serves as a tidal current collecting device, which collects tidal currents into the rectifying channel 43 and accelerates the tidal currents collected in the rectifying channel 43. The collected and accelerated tidal currents drive the capturing member 42 to rotate, and the capturing member 42 drives the rotor of the tidal current energy generator to rotate, so that the tidal current energy generator generates electricity.

[0039] In this embodiment, the tidal energy capture component 40 also includes a detection component, an adjustment component and a control component. The detection component is arranged on the seabed anchor body 22 to detect the tidal conditions at the seabed anchor body 22. The adjustment component is arranged between the seabed anchor body 22 and the fairing 41, and / or the adjustment component is arranged on the capture component 42 to adjust the working state of the tidal energy capture component 40. The control component is respectively connected to the detection component and the adjustment component signal to control the operation of the adjustment component according to the detection result of the detection component.

[0040] Among them, the detection component detects the tidal conditions (such as the speed, direction, temperature, salinity and other parameters of the tidal current) at the seabed anchor body 22, and the detection component transmits the detection result to the control component. The control component automatically controls the adjustment component to adjust the working state of the tidal energy capture component 40 according to the detection result through the preset algorithm and model, so that the tidal energy capture component 40 can efficiently capture energy under different tidal conditions.

[0041] like Figure 2As shown, the capture member 42 includes a rotating frame and a capture blade 421, the rotating frame is rotatably disposed in the fairing 41, the capture blade 421 is swingably disposed on the rotating frame, the adjusting member includes a first adjusting element, the first adjusting element is disposed on the rotating frame and is drivingly connected to the capture blade 421 to adjust the blade attack angle of the capture blade 421, and the control member is respectively connected to the detection member and the first adjusting element signal.

[0042] Specifically, the tidal current collected and accelerated by the fairing channel 43 pushes the capture blade 421, so that the capture blade 421 drives the rotating frame to rotate in the fairing 41. In this process, the speed and direction of the tidal current are detected by the detection element, and the first regulating element adjusts the blade attack angle of the capture blade 421 according to the speed and direction of the tidal current. When the tidal current speed increases, the blade attack angle of the capture blade 421 changes to maximize the energy captured by the capture blade 421; when the tidal current speed slows down, the blade attack angle of the capture blade 421 changes to reduce resistance and keep the tidal current energy capture element 40 running effectively.

[0043] In this embodiment, the fairing 41 is rotatably disposed on the seabed anchor body 22, and the rotation axis of the fairing 41 is disposed at an angle to the extension direction of the fairing channel 43. The adjusting member includes a second adjusting element, which is disposed on the seabed anchor body 22 and is drivingly connected to the fairing 41 to drive the fairing 41 to rotate, and the control member is respectively connected to the detection member and the second adjusting element signal.

[0044] Specifically, the detection component is used to detect the direction of the tidal current. When it is detected that the direction of the tidal current has changed, the control component controls the second adjusting element to drive the fairing 41 to rotate, so as to change the extension direction of the fairing channel 43, so that the tidal current energy can enter the fairing channel 43 at the most efficient angle, thereby improving the energy capture efficiency of the tidal current energy capture component 40.

[0045] In this embodiment, the fairing 41 includes an elastic cover, which is arranged to form a fairing channel. The adjusting part includes a third adjusting element, which is arranged on the seabed anchor body 22 and is drivingly connected to the fairing 41 to adjust the radial and axial dimensions of the fairing channel 43. The control part is respectively connected to the detection part and the third adjusting element signal.

[0046] Specifically, the speed of the tidal current is detected by the detection device. When a change in the direction of the tidal current is detected, the control device controls the third adjusting element to adjust the radial and axial dimensions of the rectifying channel 43 to change the shape of the rectifying channel 43. If the detection device detects that the tidal current speed is slow, the third adjusting element adjusts the rectifying channel 43 to further accelerate the tidal current, thereby improving the energy capture efficiency of the tidal current energy capture device 40.

[0047] like Figure 1As shown, the wind turbine group 30 includes three wind turbines 31 , which are arranged along the circumference of the floating platform 10 and are arranged on the floating platform 10 in an equilateral triangle layout.

[0048] like Figure 1 As shown, the floating platform 10 includes a connecting member 12 and three pontoons 11, the three pontoons 11 are arranged in an equilateral triangle, three wind turbines 31 are arranged on the three pontoons 11 in a one-to-one correspondence, and the connecting member 12 is respectively connected to the three pontoons 11. The three pontoons 11 provide support for the three wind turbines 31 respectively, and the connecting member 12 is used to maintain the support strength and stability of the floating platform 10.

[0049] In this embodiment, the wind turbine 31 adopts a vertical axis wind turbine, which lowers the center of gravity of the wind turbine 31 and reduces the capsizing risk of the offshore multi-energy integrated power generation device.
