DETAILED DESCRIPTION

[0035] The invention discloses a floating platform to reduce the construction cost of wave energy power generation, improve power generation efficiency, and thus promote the development of offshore wave energy. The invention also discloses an offshore photovoltaic and wave energy power generation floating system.

[0036] In the description of the invention, the orientations or positional relationships indicated by the terms "upper", "lower", "side", etc. are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the invention rather than requiring the invention to be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the invention.

[0037] 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, not all of the embodiments. 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.

[0038] Please refer to the attached Figure 1 -Attached Figure 4 The present invention discloses a floating platform, which includes a platform body 1, on which a photovoltaic panel 2 can be placed, thereby realizing offshore photovoltaic power generation.

[0039] The hydraulic wave energy power generation device 10 is a device for generating electricity using wave energy. The hydraulic wave energy power generation device 10 mainly includes a connecting rod 5 and a power output device 6. The power output device 6 is provided with a hydraulic cylinder, a hydraulic motor and a generator. The inner end of the connecting rod 5 is arranged in the hydraulic cylinder, and the connecting rod 5 can make a piston movement relative to the hydraulic cylinder under the drive of the waves. When the connecting rod 5 moves, the connecting rod 5 drives the hydraulic fluid in the hydraulic cylinder into the hydraulic motor, and the hydraulic motor drives the generator to generate electricity.

[0040] The present invention is provided with a first hinge assembly 3 at the first end A of the platform body 1, and a second hinge assembly 4 at the second end B. The first hinge assembly 3 is used to hinge the outer end of the connecting rod 5 of a hydraulic wave energy power generation device 10, and the outer end of the power output device 6 of the hydraulic wave energy power generation device 10 is hinged on the second hinge assembly 4 of another platform body 1 adjacent to the first end A. The second hinge assembly 4 at the second end B of the platform body 1 is used to hinge the outer end of the power output device 6 of another hydraulic wave power generation device, and the outer end of the connecting rod 5 of the other hydraulic wave power generation device is hinged on the first hinge assembly 3 of another platform body 1 adjacent to the second end B. The first end A and the second end B of the platform body 1 are opposite.

[0041] The first end A of the platform body 1 of the present invention is provided with a first hinge assembly 3, and the second end B is provided with a second hinge assembly 4, so that a hydraulic wave energy power generation device 10 can be installed between any two adjacent platform bodies 1. The floating platform of the present invention is a modular floating platform, which is convenient for mass production. The floating platform is interchangeable, thus reducing the difficulty of assembling the floating system, and any number of floating platforms can be easily assembled.

[0042] From the above description, it can be seen that the connecting rod 5 and the power output device 6 of the hydraulic wave energy power generation device 10 are arranged on two adjacent platform bodies 1. The first end A and the second end B of the platform body 1 are placed along the propagation direction of the wave, and then the two adjacent platform bodies 1 will rotate relative to each other under the drive of the wave, and then the connecting rod 5 will extend relative to the power output device 6. After the wave passes, the two adjacent platform bodies 1 will reset, thereby rotating in the opposite direction, and then the connecting rod 5 will shrink relative to the power output device 6. In this way, the connecting rod 5 forms a piston motion, so that the power output device 6 outputs electrical energy.

[0043] In the present invention, the photovoltaic panel 2 and the hydraulic wave energy power generation device 10 can be integrated on the platform body 1, so that the photovoltaic panel 2 and the hydraulic wave energy power generation device 10 share the platform body 1, the mooring system, and the power transmission setting, thereby reducing the cost of the entire power generation system, and also reducing the subsequent operation and maintenance costs. In addition, the hydraulic wave energy power generation device 10 generates electricity by rotating two adjacent platform bodies 1. Then, according to the principle of action and reaction force, the hydraulic wave energy power generation device 10 forms a damping effect on the relative rotation between the two adjacent platform bodies 1, reduces the relative rotation response between the two adjacent platform bodies 1, and improves the stability of the platform body 1, which is conducive to photovoltaic panel 2 to generate photovoltaic power.

[0044] The platform body 1 in the specific embodiment of the present invention is welded from steel plates, and the platform body 1 is in the shape of a flat plate with a rectangular parallelepiped structure. Such a design ensures that the platform body 1 has a large projected area, thereby providing sufficient installation space for the photovoltaic panel 2. In addition, the plate-shaped platform body 1 has a large waterline surface, so it has good stability, thereby providing a safe power generation site for the photovoltaic panel 2.

[0045] Please refer to the attached Figure 2 , Attachment Figure 3 , Attachment Figure 5 In order to further improve the stability of the platform body 1, a damping pool 7 is provided on the platform body 1 in the specific embodiment of the present invention, and the damping pool 7 is connected to the upper surface and the lower surface of the platform body 1. The seawater entering the damping pool 7 will slosh in the damping pool 7, dissipating the wave energy, increasing the additional damping of the platform body 1, and thus improving the stability of the platform body 1.

[0046] In the present invention, a circle of heave plates 20 are arranged in the damping pool 7 along the periphery of the bottom pool opening of the damping pool 7. The existence of the heave plates 20 will not seriously increase the steel consumption of the platform body 1, but can significantly increase the additional mass of the platform body 1, thereby further improving the stability of the platform body 1.

[0047] In order to improve the strength of the heave plate 20 in the damping pool 7, the present invention further provides a stiffening rib 21, one side of the stiffening rib 21 is connected to the heave plate 20, and the other side is connected to the side wall of the damping pool 7. There are multiple stiffening ribs 21, and the multiple stiffening ribs 21 are evenly arranged along the heave plate 20.

[0048] The present invention further provides support columns 8 on the platform body 1, and the support columns 8 are used to support the photovoltaic panels 2. The support columns 8 have a preset height. The preset height of the support columns 8 is determined according to the sea conditions of the sea area where the platform body 1 is located, ensuring that waves will not impact the photovoltaic panels 2 under extreme sea conditions. The presence of the support columns 8 allows the freeboard height of the platform body 1 to only meet the stability requirements under extreme sea conditions. Even if there are waves on the deck of the platform body 1, the waves will not impact the photovoltaic panels 2 on top of the support columns 8. The presence of the support columns 8 reduces the freeboard height of the platform body 1, thereby significantly reducing the cost of the platform body 1.

[0049] The first end A and the second end B of the platform body 1 are two ends in the length direction of the platform body 1. The length direction of the damping pool 7 in the present invention is perpendicular to the length direction of the platform body 1, and the length direction of the damping pool 7 extends along the width direction of the platform body 1. There are multiple damping pools 7, and the multiple damping pools 7 are arranged along the length direction of the platform body 1.

[0050] There are multiple groups of support columns 8, which are arranged along the width direction of the platform body 1. Each group of support columns 8 is used to support a group of photovoltaic panels 2, and the photovoltaic panels 2 extend along the length direction of the platform body 1. Multiple photovoltaic panels 2 are arranged along the width direction of the platform body 1. Such an arrangement increases the surface area of ​​the photovoltaic panels 2, which is conducive to the photovoltaic panels 2 to fully receive light, thereby facilitating photovoltaic power generation.

[0051] Each group of support columns 8 includes multiple pairs of support columns 8 arranged along the length direction of the platform body 1. In the length direction of the platform body 1, multiple pairs of support columns 8 and damping pools 7 are arranged alternately. In other words, the damping pool 7 is located between two adjacent pairs of support columns 8. Each pair of support columns 8 includes two support columns 8 arranged along the width direction of the platform body 1.

[0052] The present invention also provides a photovoltaic inverter 22 on the platform body 1. The output end of the photovoltaic panel 2 is electrically connected to the input end of the photovoltaic inverter 22. The photovoltaic inverter 22 converts the direct current of the photovoltaic panel 2 into alternating current. The output end of the photovoltaic inverter 22 and the output end of the power output device 6 are both electrically connected to the power transmission equipment, and the power transmission equipment outputs the electric energy generated by the photovoltaic panel 2 and the hydraulic wave energy power generation device 10.

[0053] From the above description, it can be seen that the hydraulic wave power generation device 10 generates electricity by the relative rotation of two adjacent platform bodies 1. In order to facilitate the rotation required by the hydraulic wave power generation device between the two adjacent platform bodies 1, the present invention makes the following design, please refer to the attached Figure 4 , Attachment Figure 6 , Attachment Figure 7: An articulated connector 11 is provided between two adjacent platform bodies 1. The articulated connector 11 specifically comprises: a double pin ear 16, a single pin ear 17 and a pin shaft 19. The double pin ear 16 and the single pin ear 17 are provided on two adjacent platform bodies 1, the single pin ear 17 is located in the cavity of the double pin ear 16, and the pin shaft 19 passes through the double pin ear 19 and the single pin ear 17.

[0054] In the specific embodiment of the present invention, a stopper 18 is provided on the upper part of the double pin ear 16, and the stopper 18 protrudes into the cavity of the double pin ear 16. The stopper 18 is located above the single pin ear 17. When the single pin ear 17 rotates to a certain extent relative to the double pin ear 16, the single pin ear 17 will be limited by the stopper 18 and cannot continue to rotate, so that the platform body 1 can be prevented from rotating greatly under extreme sea conditions and causing collision.

[0055] In a specific design, the position of the limiter 18 can be set according to the maximum angle allowed for the single pin ear 17 to rotate. If the maximum angle allowed for the single pin ear 17 to rotate is large, the limiter 18 is set away from the platform body 1 where the single pin ear 17 is located; if the maximum angle allowed for the single pin ear 17 to rotate is small, the limiter 18 is set close to the platform body 1 where the single pin ear 17 is located. In a specific embodiment of the present invention, the maximum angle allowed for the single pin ear 17 to rotate is limited to 20°. Specifically, two limiters 18 can be set on the double pin ear 16, and the two limiters 18 are symmetrical about the single pin ear 17. The limiter 18 can specifically be a limit stopper.

[0056] In a specific embodiment of the present invention, a double pin ear 16 of an articulated connector 11 is provided on the side end surface of the first end A of the platform body 1, and a single pin ear 17 of the articulated connector 11 is provided on another platform body 1 adjacent to the first end A of the platform body 1. A single pin ear 17 of another articulated connector 11 is provided on the side end surface of the second end B of the platform body 1, and a double pin ear 16 of the other articulated connector 11 is provided on another platform body 1 adjacent to the second end B of the platform body 1. Such a design improves the modularity of the platform body 1, so that any two adjacent platform bodies 1 can be articulated through the articulated connector 11.

[0057] The double pin ears 16 and the single pin ears 17 are arranged on the side end surfaces of the corresponding platform bodies 1, and the double pin ears 16 and the single pin ears 17 both protrude in the direction away from the platform bodies 1 where they are located, so that there is sufficient rotation space between the two adjacent platform bodies 1 after being hinged by the hinge connector 11, so as to allow relative rotation between the two adjacent platform bodies 1, thereby ensuring that the connecting rod 5 of the hydraulic wave energy power generation device 10 can be smoothly extended and retracted.

[0058] From the above description, it can be seen that the first end A of the platform body 1 is provided with a first hinge assembly 3, and the first hinge assembly 3 is used to hinge the outer end of the connecting rod 5 of a hydraulic wave energy power generation device 10. The second end B of the platform body 1 is provided with a second hinge assembly 4, and the second hinge assembly 4 is used to hinge the outer end of the power output device 6 of another hydraulic wave energy power generation device 10. For details, please refer to the attached Figure 6 and attached Figure 7 The first hinge assembly 3 includes a first hinge 13 and a first fixing seat 12. The first fixing seat 12 is arranged on the upper end surface of the first end A of the platform body 1. The outer end of the connecting rod 5 is hinged to the first fixing seat 12 through the first hinge 13. The second hinge assembly 4 includes a second hinge 15 and a second fixing seat 14. The second fixing seat 14 is arranged on the upper end surface of the second end B of the platform body 1. The outer end of the power output end is hinged to the second fixing seat 14 through the second hinge 15.

[0059] For the same hydraulic wave energy power generation device 10, the outer end of its connecting rod 5 and the outer end of the power output device 6 are respectively hinged on the first fixing seat 12 and the second fixing seat 14 of the two platform bodies 1, and the first fixing seat 12 and the second fixing seat 14 are respectively arranged on the upper end surfaces of the two platform bodies 1, thereby ensuring that there is a sufficient distance between the first fixing seat 12 and the second fixing seat 14 to ensure that the connecting rod 5 has a sufficient telescopic stroke to improve the power generation efficiency.

[0060] The articulated connector 11 is used to promote the required rotation of the hydraulic wave energy power generation device 10 between two adjacent platform bodies 1. If two articulated connectors 11 are provided between two adjacent platform bodies 1, the two articulated connectors 11 are provided at both ends of the width direction of the platform body 1, so that the platform body 1 can be promoted to rotate smoothly as a whole.

[0061] The present invention also provides a control cabinet 23 on the platform body 1, and the control cabinet 23 controls the hydraulic wave energy power generation device 10, for example, by controlling the flow of the hydraulic fluid to avoid rapid expansion and contraction of the connecting rod 5 under extreme sea conditions, thereby avoiding damage to the hydraulic wave energy power generation device 10. Further, the photovoltaic inverter 22 and the control cabinet 23 are respectively arranged at the first end A and the second end B of the platform body 1. The photovoltaic inverter 22 is located between the two first hinge assemblies 3, and the control cabinet 23 is located between the two second hinge assemblies 4.

The above-mentioned floating platform has the above-mentioned effects. The offshore photovoltaic and wave energy power generation floating system having the above-mentioned floating platform also has the above-mentioned effects, so it will not be repeated in this article.

[0063] Specifically, multiple (two or more) floating platforms in the floating system are arranged in a row along the propagation direction of the waves. Figure 1 The mid-floating system consists of four floating platforms. Figure 2 The mid-floating system consists of two floating platforms.

[0064] In a row of floating platforms, mooring cables 9 are provided on the floating platforms at both ends.

[0065] Finally, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the phrase "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.
