Description

Technical Field

[0001] The invention relates to the technical field of offshore photovoltaics, and in particular to a three-dimensional clam-type self-balancing offshore photovoltaic power generation floating platform. Background Art

[0002] At present, offshore photovoltaic power stations are mainly divided into two types: pile-based fixed type and floating type. The pile-based fixed type is suitable for sites with shallow water levels, no geological disasters such as site subsidence, and small water level changes. The floating offshore photovoltaic power station is suitable for deep sea areas. It replaces ground piles with anchors and has higher flexibility. However, existing floating photovoltaics have problems such as low structural strength, poor stability, and poor wind and wave resistance. Therefore, how to improve the stability, wind and wave resistance, and corrosion resistance of offshore floating photovoltaics has become a technical difficulty in the development of marine floating photovoltaics. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a three-dimensional clam-type self-balancing offshore photovoltaic power generation floating platform.

[0004] The technical solution of the present invention to solve the above technical problems is as follows:

[0005] A three-dimensional clam-type self-balancing offshore photovoltaic power generation floating platform, comprising a main structure, an anchoring system, a photovoltaic module, and a buoyancy system for providing buoyancy;

[0006] The main structure includes a central frame, columns and connecting rods, wherein the columns are located inside the central frame, and the two ends of the connecting rods are respectively connected to the columns and the central frame, and the connecting rods are respectively connected to the columns and the central frame from the upper, middle and lower layers, and a gravity weight is provided below the columns;

[0007] The anchoring system is connected to the bottom of the central frame to provide anchoring for the platform;

[0008] The photovoltaic components are installed on a truss, and the truss is located on a connecting rod on the upper layer of the water.

[0009] The beneficial effects of adopting the above technical solution are: the photovoltaic components are away from the water surface layer, which reduces the impact of seawater. By setting up an anchoring system, it can serve as an anchoring point. The anchoring point serves as the anchoring point of multiple platforms, and the gravity weight is connected under the column to ensure that the entire platform is not easy to tip over, thereby helping to maintain the overall center of gravity. The overall structure of the present invention is breathable and water-permeable, with low wind resistance, low water resistance, less impact of surges, and light structure. While ensuring the stability of the overall structure, the ability of the entire floating platform to resist wind and waves is improved by adding a flexible structure. In addition, the platform also has the characteristics of factory molding, easy installation, and easy maintenance.

[0010] Furthermore, the anchoring system includes an anchor cable and an anchor rod, wherein the upper end of the anchor cable is connected to the damper, and the lower end of the anchor cable is connected to the anchor rod.

[0011] Furthermore, the damper is connected to the bottom of the central frame, and the damper is a combined tension-contraction cable damper.

[0012] The beneficial effect of adopting the above technical solution is that the damper is connected to the central frame to ensure that the entire platform can rise and fall with the sea level, and at the same time cooperates with the gravity weight to stabilize the platform.

[0013] Furthermore, the buoyancy of the buoyancy system is provided by two parts, one part is provided by the central frame, and the other part is provided by the flexible floating blocks wrapped around the central frame and the connecting rods.

[0014] The beneficial effect of adopting the above technical solution is to ensure the buoyancy of the entire platform.

[0015] Furthermore, the central frame is a hollow structure.

[0016] Furthermore, the central frame is filled with foam.

[0017] The beneficial effect of adopting the above technical solution is that the central frame is filled with foam to play a sealing role.

[0018] Furthermore, a spare airbag is provided on the central frame for temporary maintenance.

[0019] Furthermore, the central frame and columns are made of basalt fiber or anti-corrosion steel pipes.

[0020] Furthermore, the connecting rod is a rigid connecting rod made of basalt fiber or anti-corrosion steel pipe, or a structure combined with a flexible cable.

[0021] The beneficial effect of adopting the above technical solution is that the central frame and connecting rods are factory-made from basalt fiber, with a light structure, high strength and good corrosion resistance, ensuring the stability and durability of the overall structure.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] Underwater grouting anchor piles (rods) or gravity anchors, combined with gravity weights, help stabilize the floating body and provide anchoring points. At the same time, the combined tension and contraction cable damper ensures that the platform floats with the rise and fall of the water surface, allowing the platform to produce synchronous displacement under the action of wind, waves and currents.

[0028] The principles and features of the present invention are described below in conjunction with all the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0029] The embodiment of the present invention discloses a three-dimensional clam-type self-balancing offshore photovoltaic power generation floating platform.

[0030] Reference Figure 1-Figure 3 A three-dimensional clam-type self-balancing offshore photovoltaic power generation floating platform includes a main structure 1, an anchoring system 2, a photovoltaic module 3, and a buoyancy system for providing buoyancy.

[0031] The main structure 1 includes a central frame 11, columns 12 and connecting rods 13. Among them, the central frame 11 is a circular ring structure or a polygonal structure, which has a large surface area, better stability and practicality, and ensures the maximum utilization of resources. In an embodiment of the present invention, the central frame 11 is factory-made from basalt fiber, which has a light structure, high strength and good corrosion resistance, ensuring the stability and durability of the overall structure. The central frame 11 is a hollow structure, which can better provide buoyancy, or the central frame 11 is filled with foam, which can not only play a sealing role, but also further provide buoyancy. The central frame 11 is provided with a spare airbag 5 for temporary maintenance, and at the same time can ensure the buoyancy of the platform as a whole.

[0032] Ginseng Figure 1 and Figure 2 The buoyancy of the buoyancy system is provided by two parts, one part is provided by the central frame 11, and the other part is provided by the flexible floating blocks 4 wrapped around the central frame 11 and the connecting rods 13 to ensure the buoyancy of the entire platform.

[0033] It should be noted that the flexible floating block 4 and the backup air bag 5 of the present invention are only schematically drawn in the figure. Figure 1 and Figure 2As shown, the total number of flexible floats 4 and spare air bags 5 is not shown, and the number of spare air bags 5 can be flexibly set as needed. In order to provide greater buoyancy and ensure the balance of the center frame 11, the flexible floats 4 are generally chosen to be uniformly arranged around the circumference of the center frame 11.

[0034] The column 12 is a rigid column, and the column 12 is located inside the central frame 11. When the central frame 11 is a circular ring structure, the column 12 is located at the center of the central frame 11. The two ends of the connecting rod 13 are respectively connected to the column 12 and the central frame 11, and the two ends of the connecting rod 13 are connected to the column 12 and the central frame 11 in a fixed connection. The column 12 is made of basalt fiber or anti-corrosion steel pipe, and the connecting rod 13 is a rigid connecting rod made of basalt fiber or anti-corrosion steel pipe or a structure combined with a flexible cable, which has a light structure, high strength and good corrosion resistance, ensuring the stability and durability of the overall structure.

[0035] The column 12 includes a bottom column 121, a middle column 122 and an upper plate 123. The middle column 122 is located between the bottom column 121 and the upper plate 123. The bottom column 121 is a truncated cone structure, and the minimum diameter of the bottom column 121 is greater than the diameter of the middle column 122. The middle column 122 is a cylindrical structure. The upper plate 123 is higher than the top surface of the center frame 11, and the bottom column 121 is lower than the ground of the center frame 11. When the column 12 and the center frame 11 are connected by the connecting rod 13, a three-dimensional structure can be formed. The three form the column 12 structure, which is used to connect with the connecting rod 13 to achieve the purpose of fixing the column 12, the connecting rod 13 and the center frame 11. Figure 1 shown.

[0036] The connecting rods 13 connect the columns 12 and the central frame 11 from the upper, middle and lower layers respectively, so that the entire platform has a three-dimensional structure. Figure 1 As shown, a gravity weight 7 is provided under the column 12, and one end of the gravity weight 7 is fixed to the bottom of the column 12 by an iron chain, so as to ensure that the entire platform is not prone to tipping over and help maintain the overall center of gravity. The anchor system 2 is fixedly connected to the bottom of the central frame 11. When the central frame 11 is a circular ring structure, the anchor system 2 is evenly arranged along the circumference of the central frame 11 to provide anchor points and increase the stability of the overall structure.

[0037] Reference Figure 1 and Figure 3 The photovoltaic assembly 3 is installed on the truss 6, and the truss 6 is installed on the connecting rod 13 of the upper water layer. The photovoltaic assembly 3 is far away from the water surface, which reduces the impact of seawater.

[0038] The overall structure of the present invention is water-permeable, breathable and water-permeable, has small wind resistance, small water resistance, is less affected by surges, and has a light structure. While ensuring the stability of the overall structure, the ability of the entire floating platform to resist wind and waves is improved by adding a flexible structure. In addition, the platform also has the characteristics of factory molding, easy installation, and convenient maintenance and repair.

[0039] Reference Figure 1 and Figure 2 The anchoring system 2 includes an anchor cable 21 and an anchor rod 22. The upper end of the anchor cable 21 is fixedly connected to a damper 23, and the lower end of the anchor cable 21 is fixedly connected to the anchor rod 22. The damper 23 is fixedly connected to the bottom of the central frame 11 at one end away from the anchor cable 21. The damper 23 is a combined tension-reduction cable damper, and the anchor rod 22 is an underwater anchor rod. The damper 23 is used to ensure that the entire platform can rise and fall with the sea level, and at the same time cooperates with the gravity weight to stabilize the platform.
