Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation equipment technology, and in particular to a floating photovoltaic support structure for marine applications and a photovoltaic array having the support structure. Background Technology

[0002] Floating photovoltaic arrays (hereinafter referred to as photovoltaic arrays) are power generation facilities that install photovoltaic panels on photovoltaic brackets and float on the water surface with the help of floating structures. They are suitable for lakes, reservoirs and near-shore waters. They get rid of the dependence of land photovoltaics on land and effectively solve the problem of land resource shortage. They are one of the important development directions of the photovoltaic industry.

[0003] Today's photovoltaic arrays mainly consist of photovoltaic panels and photovoltaic supports. Existing photovoltaic supports are composed of an outer annular float and a central float, with several spokes radiating out between the annular float and the central float. Photovoltaic panels are installed on the spokes to form a photovoltaic array (see the application for a marine floating support filed by the applicant on April 1, 2025, with the application publication number CN120156650A).

[0004] However, in existing photovoltaic (PV) mounting systems, the two ends of the spokes used for mounting the PV panels need to be installed between an outer ring float and a central float. After the PV panels are arranged, a large triangular space is formed between the PV panels on adjacent spokes (see reference). Figure 1 (Region A), therefore, the existing photovoltaic support system has the disadvantage of low space utilization.

[0005] Secondly, the existing photovoltaic mounting systems lack maintenance access, making installation and maintenance extremely inconvenient.

[0006] In summary, necessary improvements need to be made to the existing photovoltaic support system. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a floating photovoltaic support for the sea and a photovoltaic array with the support, so as to solve the problems mentioned in the background technology.

[0008] The technical solution of this utility model is as follows: a photovoltaic array, including photovoltaic panels and photovoltaic support (also called a floating photovoltaic support at sea, the same below).

[0009] The photovoltaic support structure of this utility model includes at least three coaxially arranged floating structures, which are spaced apart from each other, and an installation area for arranging photovoltaic panels is formed between adjacent floating structures.

[0010] By adopting the above technical solution: The photovoltaic bracket of this utility model is different from the existing technology. The existing technology has only two floating structures: a central floating body and an outer ring floating body. As a result, the two ends of the spokes (or support structure) used to install the photovoltaic panels can only extend from the center of the photovoltaic bracket to the outer ring floating body. This results in a large triangular space between the photovoltaic panels of adjacent spokes, so the space utilization rate is not high. The floating structure of this utility model has three or more floating structures, with an installation area formed between each pair of adjacent floating structures. The installation area is used to arrange the crossbars of this utility model. Therefore, the two ends of the crossbars (used to support the photovoltaic panels and the structure for installing the photovoltaic panels) of this utility model do not need to extend from the center of the photovoltaic bracket. This can greatly reduce the triangular space and thus improve the space utilization rate. According to tests, under the same diameter photovoltaic bracket, this utility model can accommodate 30% more photovoltaic panels than the prior art.

[0011] Secondly, the multi-ring floating structure has better structural strength than the single-ring floating structure in existing technologies.

[0012] Preferably, the floating structure of this utility model includes: Circular tube float; Several connecting components are connected to the circular tube float and are distributed circumferentially at intervals; Each floating structure has a corresponding connecting component, and the photovoltaic panels can be installed between the corresponding connecting components through a supporting structure.

[0013] Preferably, the connecting component includes: The annular connector is connected to the circular tube float. Hinged base, mounted on the annular connector; The photovoltaic panel's support structure is hinged to the hinge seat via a hinge connector.

[0014] Preferably, the support structure includes: The crossbar is hinged to the hinge seat via a hinge connector; Several photovoltaic panel frames are installed at intervals on the horizontal bar, and are used for photovoltaic panel installation.

[0015] Preferably, the hinge seat is detachably connected to the annular connector.

[0016] Preferably, the hinge seat is a U-shaped connector.

[0017] By adopting the above technical solution: This invention uses a hinged connection between the connecting component and the support structure. Under wave conditions, this hinged connection allows the support structure to swing around the hinge point, thus preventing the support structure from breaking.

[0018] Preferably, the circular tube float of the floating structure has at least two sections, and also includes a footplate installed between adjacent floating structures.

[0019] By adopting the above technical solution: The floating structure of this utility model can be composed of multiple circular tube floats. Combined with the footboard of this utility model, it solves the problem that existing photovoltaic brackets do not have maintenance access. In other words, maintenance personnel can move to any position of the photovoltaic bracket using the footboard and the circular tube floats as support. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: like Figure 2 As shown, this embodiment provides a photovoltaic array, including a photovoltaic panel 10 and a photovoltaic support.

[0024] In this embodiment, the photovoltaic support is composed of multiple coaxially arranged floating structures 2. The present invention does not limit the number of floating structures. Taking three as an example, that is, the number of floating structures 2 in this embodiment can be three, and each floating structure 2 is spaced apart, forming an installation area for arranging photovoltaic panels 10 between adjacent floating structures 2.

[0025] refer to Figure 2 In this embodiment, the photovoltaic panels can be installed on the floating structure using existing brackets (such as the bracket unit in prior art CN120156650A). Compared with the prior art, the advantage of this embodiment is that by arranging multiple floating structures, an installation area for photovoltaic panels can be formed between two floating structures. This is achieved by comparing the photovoltaic panels with existing technologies (such as...). Figure 1 ) and this embodiment (such as Figure 2 As can be seen from this, the triangular space formed between adjacent photovoltaic panels in this embodiment is smaller than that in the prior art, so the space utilization rate of this embodiment is higher.

[0026] The bracket used in this embodiment is existing technology, so it will not be described in detail here.

[0027] Example 2 differs from Example 1 in that: The support frame (i.e., the support structure of this embodiment) and the floating structure in this embodiment can be arranged as follows: refer to Figures 3-11 As shown, the floating structure 2 includes: Circular tube float 20, in this embodiment each float structure has 2 circular tube floats 20; Several connecting parts 21 are connected to the circular tube float 20 and are distributed circumferentially; Among them, the connecting parts 21 on each floating structure 2 can correspond one-to-one, and the photovoltaic panel 10 can be installed between the corresponding connecting parts 21 through the support structure.

[0028] like Figures 4-6As shown, in this embodiment: the connecting component 21 includes: The annular connector 210 is connected to the circular tube float 20. In this embodiment, the annular connector 210 has two mounting ports 211. After installation, each circular tube float 20 passes through the mounting port 211 of each annular connector 210. Hinged base 212 is mounted on annular connector 210; The photovoltaic panel's support structure is hinged to the hinge seat 212 via hinge 51.

[0029] In this embodiment, the support structure includes: The crossbar 40 is hinged to the hinge seat 212 via the hinge 51; Several photovoltaic panel frames 41 are installed at intervals on the crossbars 40, and are used for mounting photovoltaic panels 10, as shown in the reference. Figure 8 In this embodiment, one side of the photovoltaic panel frame 41 has a support leg 41a, which is installed to the crossbar 40 by bolts 212a. The other side of the photovoltaic panel frame 41 is connected to the crossbar 40 by bolts 212a and a clamping member.

[0030] like Figures 9-10 As shown, the cross section of the crossbar 40 is U-shaped, and the groove of the crossbar is rolled inward to form a folded edge 40a. The overall shape of the support leg 41a is U-shaped. The lower end 41c of the support leg 41a is connected to a limiting block 41b by a bolt 212a (the bottom of the limiting block 41b may be provided with a nut that matches the bolt 212a). The length of the limiting block is greater than the groove of the crossbar. Therefore, by adjusting the lower end 41c of the support leg... Bolt 212a can fix the support leg 41a to the crossbar 40. The upper end 41d of the support leg 41a is connected to the clamping plate 41e by bolt 212a. The clamping plate 41e and the upper end 41d of the support leg are used to fix the photovoltaic panel frame. Similarly, the clamping member 41p in this embodiment also has a limiting block 41b and a clamping plate 41e. The gap between the clamping plate 41e and the clamping member 41p is used to fix the photovoltaic panel frame 41. The cooperation of the limiting block 41b and bolt 212a can fix the clamping member 41p to the crossbar.

[0031] refer to Figures 5-6 In this embodiment, the hinge seat 212 can be detachably connected to the annular connector 210 by means of bolts 212a.

[0032] In this embodiment, the hinge seat 212 is a U-shaped connector. The U-shaped connector 212 in this embodiment is provided with a pin hole 50. The hinge 51 in this embodiment is a pin that passes through the pin hole 50. During assembly, the crossbar is also provided with a pin hole. When the pin hole on the U-shaped connector 212 and the crossbar are aligned, the pin is inserted to achieve the fit. The two ends of the pin can be inserted with limit pins 51a to prevent the pin from falling off.

[0033] In this embodiment, a footboard 3 is also included, which is installed between adjacent floating structures 2. The footboard 3 is connected to the circular tube floating body 20. (Refer to...) Figure 7 In this embodiment, the pedal 3 can also be connected to the circular tube float 20 via the crossbar 40 and the connecting component 21. The pedal 3 is installed on the crossbar 40 via bolts 212a and fasteners.

[0034] In this embodiment, a threaded hole 6 is provided on the photovoltaic panel frame 41 for the photovoltaic panel 10 to be installed with the photovoltaic panel frame 41.

[0035] refer to Figure 11 In this embodiment, the fixing member has a clamping block 70, and the clamping block 70 is connected to a bottom block 71 by a bolt 212a. The structure of the bottom block 71 can be the same as that of the limiting block 41b (the bottom of the bottom block can also be provided with a nut that mates with the bolt 212a). When fixing the pedal, the bolt 212a passes through the mesh on the pedal and connects to the bottom block. By adjusting the tightness of the bolt, the pedal is fixed to the crossbar 40 by the clamping block.

[0036] The connection method between the support structure and the circular tube float in this embodiment is different from that in Embodiment 1. In this embodiment, the crossbar and the circular tube float can be hinged by a pin. In this way, under the influence of waves, the crossbar can swing around the pin at a certain angle, thereby preventing the crossbar from breaking.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
