Description

Technical Field

[0001] The present invention relates to the field of marine photovoltaic technology, and in particular to a radiation reinforced floating marine photovoltaic power generation support system. Background Art

[0002] Due to the scarcity of land resources, photovoltaic power generation is gradually shifting from land to the ocean. Currently, marine photovoltaic power generation technologies are mainly divided into two types: fixed-pile photovoltaic power generation technology and floating photovoltaic power generation technology. Fixed-pile photovoltaic power generation technology is mainly suitable for areas such as shallow lakes and near-shore mudflats, while floating photovoltaic power generation is not only suitable for these areas, but also for deep sea and offshore areas.

[0003] Existing floating photovoltaic power generation systems typically consist of a ring-shaped float made of HDPE (high-density polyethylene) engineering plastic. A film is placed inside the float, and photovoltaic panels are mounted on the film. Together, the float and the film allow the entire system to float on the sea surface. Because the film adheres closely to the water's surface, this photovoltaic power generation system effectively adapts to surface fluctuations, allowing the entire system to rise and fall with the waves. However, when overtopping waves occur, water easily accumulates inside the float, making it difficult to drain. Summary of the Invention

DETAILED DESCRIPTION

[0023] The following embodiments of the technical solution of the present invention will be described in detail with reference to specific embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only used as examples and are not intended to limit the scope of protection of the present invention.

[0024] It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0025] See also Figures 1 to 4 The present application provides a radiation reinforced floating offshore photovoltaic power generation support system, including a floating structure and a thin film. The floating structure is a conical body whose height gradually decreases from the center to its radial direction. It includes an outer floating body 1, an inner floating body 3 and a connecting structure 2 that are coaxially arranged and have an annular structure. The connecting structure 2 includes a tensioning tendon 21, which is connected between the outer floating body 1 and the inner floating body 3; the thin film includes a top membrane 5 and a bottom membrane 6, the top membrane 5 is laid on the top surface of the floating structure, and the bottom membrane 6 is laid on the bottom surface of the floating structure.

[0026] The present application adopts a double concentric ring float structure consisting of an outer float 1 and an inner float 3. The inner and outer floats 1 are connected by a connecting structure 2. The float structure is a cone whose height gradually decreases from the center to its radial direction. This allows the support system of the present application to dissipate the force of waves through its own flexible deformation under the action of small waves. In large wave sea conditions, the effect of waves on the structure can be reduced through overall movement. When local overtopping occurs, the height difference of the top surface of the float can be used to achieve rapid discharge of seawater. This ensures that the photovoltaic panels are always above the water surface, thereby achieving more stable power generation of the photovoltaic panel structure.

[0027] The floating structure is a cone structure as a whole, and the height of the floating structure gradually decreases from the center to its radial direction, so that its top surface is a cone surface, with a structure that is thick in the middle and thin at the edges.

[0028] The outer floating body 1 includes an outer outer tube 11, an outer inner tube 12, an outer radial fixing plate 14 and an outer reinforcing main beam 13. The outer outer tube 11 and the outer inner tube 12 can be hollow tubes made of HDPE (high-density polyethylene) material, which can be directly purchased as finished products to provide overall buoyancy; the outer reinforcing main beam 13 can be made of metal material, which is connected to the outer outer tube 11 and the outer inner tube 12 through the outer radial fixing plate 14.

[0029] Specifically, the outer tube 11, the outer inner tube 12, and the outer reinforcing main beam 13 are all annular structures and coaxially arranged. The outer reinforcing main beam 13 is located between the outer tube 11 and the outer inner tube 12. Multiple outer radial fixing plates 14 are spaced apart along the circumference of the outer buoy 1. Each outer radial fixing plate 14 is arranged radially along the outer buoy 1. A through hole is provided at one end of each outer radial fixing plate 14 for the outer tube 11 or the outer inner tube 12 to pass through. The outer tube 11 or the outer inner tube 12 passes through this through hole to connect with the corresponding outer radial fixing plate 14. The other end of each outer radial fixing plate 14 is welded to the corresponding side of the outer reinforcing main beam 13.

[0030] The inner floating body 3 includes an inner outer tube 31, an inner inner tube 32, an inner radial fixing plate 34 and an inner reinforcing main beam 33. The inner outer tube 31 and the inner inner tube 32 can be hollow tubes made of HDPE (high-density polyethylene) material, which can be directly purchased as finished products to provide overall buoyancy; the inner reinforcing main beam 33 can be made of metal material, which is connected to the inner outer tube 31 and the inner inner tube 32 through the inner radial fixing plate 34.

[0031] Specifically, the inner outer tube 31, inner inner tube 32, and inner reinforcing main beam 33 are all annular structures and are coaxially arranged. The inner reinforcing main beam 33 is located between the inner outer tube 31 and the inner inner tube 32. Multiple inner radial fixing plates 34 are spaced apart along the circumference of the inner buoy 3. Each inner radial fixing plate 34 is arranged radially along the inner buoy 3. One end of the inner radial fixing plate 34 is provided with a through hole for the inner outer tube 31 or the inner inner tube 32 to pass through. The inner outer tube 31 or the inner inner tube 32 passes through this through hole to connect with the corresponding inner radial fixing plate 34. The other end of the inner radial fixing plate 34 is welded to the corresponding side of the outer reinforcing main beam 13.

[0032] The connecting structure 2 includes tensioning tendons 21 and foam 22. A plurality of tensioning tendons 21 are arranged at circumferential intervals along the connecting structure 2. Each group of tensioning tendons 21 includes a first tensioning tendon 211 and a second tensioning tendon 212 arranged in an X-shaped cross. The inner end of the first tensioning tendon 211 is hinged to the top of the inner outer tube 31, and its outer end is hinged to the bottom of the outer inner tube 12. The inner end of the second tensioning tendon 212 is hinged to the bottom of the inner outer tube 31, and its outer end is hinged to the top of the outer inner tube 12. By arranging the tensioning tendons 21 of the above structure, when the inner float 3 and the outer float 1 have relative movement, the relative movement of the inner float 3 and the outer float 1 can be resisted by the tension of the first tensioning tendon 211 or the second tensioning tendon 212, thereby ensuring the integrity of the support system. The foam 22 is filled between the top membrane 5 and the bottom membrane 6 to provide further buoyancy for the support system and greatly improve the rigidity of the top membrane 5, thereby facilitating the installation of the photovoltaic panels.

[0033] The top membrane 5 is used to lay photovoltaic panels. The outer edge of the top membrane 5 can be fixedly connected to the top of the outer outer tube 11 of the outer floating body 1, or to the top of the outer reinforcing main beam 13. The center of the top membrane 5 can be fixedly connected to the top of the inner reinforcing main beam 33. Several radial and circumferential tensioning ropes 4 are arranged inside the top membrane 5 to increase its support strength. The photovoltaic panels are laid on the top membrane 5.

[0034] The bottom membrane 6 is used to reduce the impact of waves on the floating body during the movement of the floating body. The edge of the bottom membrane 6 can be fixedly connected to the bottom surface of the outer inner tube 12 of the outer floating body 1, and can also be fixedly connected to the bottom surface of the outer reinforcing main beam 13; the position near the center of the bottom membrane 6 can be fixedly connected to the bottom surface of the inner reinforcing main beam 33, and a number of radial and circumferential tensioning ropes 4 can be arranged inside the bottom membrane 6.

[0035] In order to facilitate later maintenance, an operation and maintenance platform is also included, which is arranged on the top membrane 5. The operation and maintenance platform includes an annular platform 71 and a radial platform 72. The annular platform 71 is installed on the inner side of the corresponding outer floating body 1, and the radial platform 72 is a cross-shaped structure, and its outer end is connected to the annular platform 71.
