Description

Technical Field

[0002] How to install photovoltaic power generation equipment in complex environments such as oceans, mountains, and lakes has become one of the current research hotspots in the field of renewable energy power generation. To this end, engineers have come up with a variety of technical solutions, including floating, flexible film, and bracket types.

[0003] Among them, the existing common photovoltaic support structures include: a large-span photovoltaic steel truss structure disclosed in the Chinese invention patent with publication number CN116623798A, a large-span offshore photovoltaic truss support structure disclosed in the utility model patent with publication number CN220935052U, a large-span offshore photovoltaic support and its transportation method disclosed in the Chinese invention patent with publication number CN118508842A, a pile foundation fixed offshore photovoltaic array support disclosed in the Chinese utility model patent with publication number CN219697529U, etc.

[0004] The above patents all use multiple support piles to support the truss structure, and the photovoltaic panels are installed on the truss structure. This solution is feasible in shallow seas and shallow lakes, but when the water depth increases, all the support piles must be lengthened and thickened, resulting in a sharp increase in costs. Ultimately, due to economic reasons, it cannot be used in deeper oceans and lakes.

[0005] To this end, the Chinese utility model with announcement number CN220746998U discloses a single-pile offshore photovoltaic support structure, which adopts a single pile support to solve the technical defect of the small application range of multi-pile support. However, the single-pile offshore photovoltaic support structure is relatively high in height, the structure is relatively complex, and the overall setting is inclined. This structural form has poor stability, resulting in the area of ​​the photovoltaic support structure cannot be too large, and the application scenarios are still greatly limited. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a single-pile large-area truss-type regular polygonal photovoltaic support, a photovoltaic system and a construction method, so as to solve the technical defects in the prior art that the application scope of multi-pile supports is small, the structural stability of single-pile supports is poor, and the area of ​​the supporting structure is small.

[0007] In order to solve the above technical problems, the technical solution provided by the present invention is as follows: a single-pile large-area truss regular polygon photovoltaic support, comprising at least:

The diameter of the inscribed circle of the regular polygon can be large or small, generally 5-300 meters; since the center of gravity of the photovoltaic support is concentrated on the central tube, only one support pile is needed, which not only saves costs but also reduces the use of land. It can be flexibly used in places where piling construction is difficult, such as oceans, hills, and river valleys.

[0014] In addition, the setting of upper and lower cables effectively shares the force borne by the radial truss and improves the reliability of the overall structure.

[0060] Embodiment 1

[0061] A single pile large area truss regular polygon photovoltaic support in this embodiment, such as Figure 1-Figure 3 As shown, it includes a central tube 5 , a circumferential truss 1 , a radial truss 2 , a lower cable 41 and an upper cable 42 . The axial length of the central tube 5 is greater than the height of the circumferential truss 1 and the radial truss 2 .

[0062] The lower end of the central tube 5 is provided with a lower mounting structure 51, and the upper end is provided with an upper mounting structure 52. It should be noted that in this embodiment, only the lower end of the central tube 5 may be provided with the lower mounting structure 51, and no mounting structure may be provided at the upper end.

[0063] In this embodiment, as a preference, the main body of the central tube 5 is a hollow steel tube structure, the diameter of which is generally greater than 1 meter and less than 15 meters; the height is generally greater than 1 meter and less than 20 meters. As a preference, in this embodiment, the lower mounting structure 51 and the upper mounting structure 52 are flanges. Of course, the flange is only a preferred implementation scheme in this embodiment, and other mounting structures of existing engineering installation fields may also be used.

[0064] In this embodiment, ten radial trusses 2 with the same structure extend along the radial direction of the central tube 5, wherein one end of the radial truss 2 is fixedly connected to the central tube 5, and the ten radial trusses 2 with the same structure are evenly distributed around the central tube, that is, the angles between two adjacent radial trusses 2 are equal.

[0065] It should be noted that, in this embodiment, ten radial trusses 2 are a preferred implementation scheme of this embodiment. Usually, at least four radial trusses 2 need to be provided.

[0066] In this embodiment, the circumferential trusses 1 are installed between two adjacent radial trusses 2, and a plurality of unilaterally connected circumferential trusses 1 form a regular polygon. A plurality of regular polygons with different sizes of inscribed circles formed by the circumferential trusses 1 are arranged along the radial direction of the central tube 5, and the circumferential trusses 1 between two adjacent radial trusses 2 are parallel to each other. In this embodiment, the diameter of the inscribed circle of the regular polygon is generally 5 meters to 300 meters.

[0067] In this embodiment, a plurality of the upper cables 41 are arranged directly above the radial trusses 2 . Preferably, the upper cables 41 correspond one-to-one to the radial trusses 2 . One end of the upper cables 41 is fixed to the central tube 5 , and the other end is fixed to the radial trusses 2 .

[0068] It should be noted that, when the diameter of the inscribed circle formed by the outermost circumferential trusses 1 is relatively large, a plurality of upper cables 41 may also be provided above each radial truss 2 .

[0069] In this embodiment, the lower cables 42 have multiple ends and are located below the radial trusses 2 and the circumferential trusses 1. The lower cables 42 include radial cables 421 corresponding to the radial trusses 2 and multiple groups of oblique cables 422 arranged crosswise with each other. One end of the radial cables 421 is fixed to the central tube 5, and the other end is fixed to the radial trusses 2; one end of the oblique cables 422 is fixed to the central tube 5, and the other end can be fixed to either the radial trusses 2 or the circumferential trusses 1.

[0070] It should be noted that, since the photovoltaic panel 3 needs to be arranged on the upper part of the photovoltaic support, in order to avoid blocking the photovoltaic panel, the upper cable 41 is arranged directly above the radial truss 2. However, since the lower cable 42 has no possibility of blocking the photovoltaic panel, the lower cable 42 can be fixed on the radial truss 2 or on the circumferential truss 1, and its arrangement is more flexible according to the structural strength requirements. In particular, the cross-arranged oblique cables 422 can improve the torsional strength of the photovoltaic support, thereby improving the stability of the overall structure.

[0071] In this embodiment, the upper cables 41 and the lower cables 42 share a portion of the force acting on the radial trusses 2, thereby improving the overall structural strength of the photovoltaic support.

[0072] Embodiment 2

[0073] The single pile large area truss regular polygon photovoltaic support of this embodiment is as follows Figure 5 As shown, the difference from the first embodiment is that in the first embodiment, the circumferential truss 1 and the radial truss 2 are both plane trusses. In this embodiment, the circumferential truss 1 is a plane truss, and the projection surface 21 of the radial truss 2 is triangular, which is a space truss.

[0074] It should be noted that both the plane truss and the space truss are prior art, and the specific structure is not described in detail in this embodiment. In this embodiment, the space truss with a triangular projection surface is the preferred implementation of this embodiment. Of course, other structural forms of space trusses in the prior art can also be used, such as a space truss with a rectangular projection surface.

[0075] Preferably, in this embodiment, the circumferential truss 1 may also be a space truss.

[0076] As is known to all, the structural strength of the space truss is greater than that of the plane truss. Therefore, the single-pile large-area truss-type regular polygon photovoltaic support of this embodiment usually adopts a space truss when the area is large, and adopts a plane truss when the area is small. For example, when the diameter of the inscribed circle of the regular polygon composed of the outermost circumferential trusses is less than 60 meters, the radial trusses 2 and the circumferential trusses 1 generally adopt plane trusses, and of course, space trusses can also be used. When the diameter of the inscribed circle of the regular polygon composed of the outermost circumferential trusses is greater than 80 meters, the radial trusses 2 and the circumferential trusses 1 generally adopt space trusses. Of course, when the structural strength meets the application environment, plane trusses can also be used. When the diameter of the inscribed circle of the regular polygon composed of the outermost circumferential trusses is between 60 meters and 80 meters, the radial trusses and the circumferential trusses can adopt plane trusses or space trusses.

[0077] Embodiment 3

[0078] A photovoltaic system of this embodiment, such as Figure 6 As shown, it includes a support pile 6 and a single pile large-area truss regular polygon photovoltaic support installed on the upper end of the support pile 6 through a lower mounting structure 51. Among them, the support pile 6 is a single one, fixedly set in the target construction area, such as the ocean, hills, river valleys, etc.

[0079] In this embodiment, the support pile 6 is a single one, which not only saves costs but also reduces the use of land, and can be flexibly applied to places where piling construction is difficult, such as oceans, hills, and river valleys.

[0080] In this embodiment, a plurality of photovoltaic panels 3 are arranged flat on the circumferential truss 1. Of course, the photovoltaic panels 3 being arranged flat on the circumferential truss 1 is a preferred implementation of this embodiment, and a plurality of support frames may be arranged on the circumferential truss 1, and the photovoltaic panels 3 are mounted on the support frames, and the mounting surfaces of the support frames are arranged at an angle, so that the photovoltaic panels 3 are arranged at an angle relative to the upper surface of the circumferential truss 1, thereby improving the efficiency of photovoltaic power generation.

[0081] It should be noted that the tilted arrangement of the photovoltaic panels by means of a support frame is a conventional arrangement in the art, and its specific structure will not be described in detail in this embodiment.

[0082] The construction method of the photovoltaic system of this embodiment includes the following steps:

[0083] S1 manufactures the single pile large area truss regular polygon photovoltaic support according to the design requirements.

[0084] S2 installs the photovoltaic panel 3 on the single pile large area truss regular polygon photovoltaic support.

[0085] S3: manufacturing the support pile 6 according to the design requirements.

[0086] S4: transport the support pile 6 to the target construction area and complete the installation.

[0087] S5: transport the component structure of step S2 to the target construction area and install it on the top of the support pile 6 by hoisting.

[0088] In this embodiment, the assembly formed in step S2 is produced in a factory as an integral structure and then transported to a designated area for installation. There is no need to install brackets on site in the construction area. The construction method is quick and convenient, reducing labor costs.

[0089] Embodiment 4

[0090] A photovoltaic system of this embodiment, such as Figure 7 As shown, the difference from the third embodiment is that a wind power generation system is also installed at the upper end of the central tube 5, and the wind power generation system includes a mounting column 71 and a wind turbine 7 located at the top of the mounting column. The lower end of the mounting column 71 is mounted on the upper end of the central tube 5 through the upper mounting structure 52.

[0091] In this embodiment, the photovoltaic power generation system and the wind power generation system are organically combined to achieve multi-energy complementarity. Taking Zhejiang as an example, a 5-megawatt wind turbine is installed on a photovoltaic bracket whose inscribed circle of the outermost regular polygon is directly 100 meters. Because the wind turbine blocks sunlight, photovoltaic power generation loses about 4.8% of its power generation throughout the year, but photovoltaic and wind turbines share the same pile foundation and power transmission equipment, saving about 20% of the cost. On the other hand, this photovoltaic bracket can be installed on the basis of existing wind power generation to save construction costs and achieve multi-energy complementarity.

[0092] The construction method of the photovoltaic system in this embodiment includes the following steps:

[0093] S1, manufacturing the single pile large area truss regular polygon photovoltaic support according to the design requirements;

[0094] S2 installs photovoltaic panels on the single pile large-area truss regular polygon photovoltaic support;

[0095] S3, manufacturing the support pile according to the design requirements;

[0096] S4, manufacturing the wind power generation system according to the design requirements;

[0097] S5: transporting the support piles to the target construction area and completing the installation;

[0098] S6: transporting the component structure of step S2 to the target construction area and installing it on the top of the support pile by hoisting;

[0099] S7: transport the wind power generation system to the target construction area and install it on the top of the central pipe by hoisting.

[0100] In short, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
