Description

Technical Field

[0001] The present invention relates to the field of photovoltaic support technology, and more specifically, to a large-span flexible photovoltaic support system. Background Art

[0002] Flexible photovoltaic bracket is a large-span photovoltaic component support structure that is fixed at both ends, designed based on a tension structure system, and uses cables as component support members. The wide application of flexible photovoltaic brackets is mainly due to its ability to solve the problem of insufficient photovoltaic land area in large-slope mountain projects in the southwest, Yunnan and Guizhou, as well as in conventional terrain. It can also be used in projects that combine photovoltaics with other industries, such as fish-light complementarity.

[0003] At present, in the actual application of flexible photovoltaic brackets, it is found that because the photovoltaic panels of the flexible photovoltaic brackets are installed in high-altitude areas and have the characteristics of large span, the installation of photovoltaic panels requires workers to work in multiple high-altitude areas, and is affected by the sagging and shaking of the cables, the installation at high altitude is more difficult. While there are great safety hazards, the efficiency of photovoltaic laying cannot be guaranteed.

[0004] In order to solve the above problems, this application proposes a large-span flexible photovoltaic support system. Summary of the invention

[0005] The purpose of the present invention is to provide a flexible photovoltaic support system capable of laying photovoltaic panels in a large span.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] A large-span flexible photovoltaic support system, comprising a photovoltaic module and a photovoltaic panel therein, an end point fixing unit and a fixing column therein, and a flexible support unit and a cable therein, wherein the photovoltaic module is located above the flexible support unit between two adjacent end point fixing units on the left and right;

[0008] The cable passes through the curved pipe on the outer side of the upper end of the fixed column to form a circular shape. The inner side of the upper end of the fixed column is provided with two upper and lower pressing wheels for squeezing the cable and driving it to move. The photovoltaic panel is fixed on the upper part of the cable through the fixing clamp below, forming a mobile support structure and a mobile laying function;

[0009] The rigid support unit is located in the lower area of ​​the photovoltaic panel, and includes a fixing seat and a support, which are respectively located at the left and right ends of the photovoltaic panel. A slide is provided on the right side of the support, and the fixing seat and the support are connected by the connecting rod inside the slide, so that adjacent photovoltaic panels are aligned to achieve a neat laying effect;

[0010] The connecting frame is located between two adjacent front and rear fixing columns. The connecting rod is also used to connect the connecting frame with the fixing seat and the support, so that the fixing seat, the support and the connecting frame are combined with each other to form a rigid support for the photovoltaic panel, forming a double support effect with the flexible support of the cable.

[0011] Beneficial effects of the present invention:

[0012] The present invention arranges the cables in a circular shape and combines the squeezing of adjacent pressure wheels, so that after the photovoltaic panel is installed on the cables, an external driving device can be directly connected to drive the cables to drive the photovoltaic panel to move to the area between the two fixed columns. This eliminates the need for workers to perform high-altitude operations in multiple areas, and allows the photovoltaic panel to be laid in high-altitude areas, forming a movable flexible support structure, which reduces the difficulty of construction and eliminates safety hazards. At the same time, there is no need to worry about the shaking and sagging of the cables affecting the laying operation.

[0013] Before transporting the photovoltaic panels, the present invention first connects the adjacent supports to the carriage through connecting rods, so that the adjacent photovoltaic panels are neatly arranged for transport. After this arrangement, the photovoltaic panels only need to be aligned in the area where the fixing columns are located to ensure the neatness of the photovoltaic panels in the area between the two fixing columns.

[0014] In addition, each group of supports is connected to the slide to form a rigid connection, and then the connecting frames at both ends are connected to the supports and slides respectively by connecting rods, which can form a rigid support structure for the photovoltaic panels in high-altitude areas, combining flexible support and rigid support, which not only improves the stability of the installation, but also prevents the sagging and shaking of the cables, prolongs the support time and reduces the failure rate.

[0032] 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.

[0033] like Figure 1 - Figure 6As shown, the present invention provides a large-span flexible photovoltaic support system, including a photovoltaic module 100 and a photovoltaic panel 110 therein, an end point fixing unit 200 and a fixing column 210 therein, and a flexible support unit 300 and a cable 310 therein, wherein the photovoltaic module 100 is located above the flexible support unit 300 between two adjacent end point fixing units 200 on the left and right;

[0034] The cable 310 passes through the curved pipe 320 on the outer side of the upper end of the fixed column 210 to form a roundabout between the two adjacent fixed columns 210 on the left and right. The upper inner side of the fixed column 210 is provided with two upper and lower pressing wheels 520 for squeezing the lower layer of the cable 310. The cable 310 is driven to move by friction through an external rotary drive device. Prior to this, the photovoltaic panel 110 is pre-fixed on the upper part of the cable 310 by the fixing clamp 120 below, thereby forming a mobile support structure and a mobile laying function, realizing long-distance laying without the need for workers to climb high in multiple places;

[0035] The rigid support unit 400 includes a fixing seat 410 and a support 420, which are respectively located at the left and right ends below the photovoltaic panel 110. A slide 430 is provided on the right side of the support 420, and the support 420 and the slide 430 are connected by a connecting rod 432 inside thereof, so that the adjacent photovoltaic panels 110 are aligned, and then the two photovoltaic panels 110 are kept aligned during movement, thereby achieving a neat laying effect, reducing the difficulty of work and having strong practicality;

[0036] The connecting frame 220 is located in the upper area between the two adjacent front and rear fixed columns 210. The connecting rod 432 is also used to connect the connecting frame 220 at the left and right ends to the fixed seat 410 and the support 420 respectively, so that the three are combined to form a rigid support for the photovoltaic panels 110 laid throughout, and form a double support effect with the flexible support of the cable 310.

[0037] The present embodiment provides a dual support structure for a photovoltaic module, wherein a photovoltaic panel 110 is first fixed above the upper cable 310 by means of a fixing clamp 120, and then when another photovoltaic panel 110 is installed, a support 420 and a slide 430 are connected in series by means of a connecting rod 432, so that adjacent photovoltaic panels 110 are aligned and placed, and then an external device drives a pressure wheel 520 to rotate, and uses an extrusion force to move the cable 310, so as to drive the photovoltaic panel 110 to move toward a fixed column 210 at the other end, thereby forming a mobile laying operation, without the need for workers to climb high in multiple areas, and realizing long-distance photovoltaic laying construction; in addition, after the photovoltaic panel 110 is laid, the support 420 and the slide 430 are respectively connected to the connecting frame 220 by means of a connecting rod 432, thereby forming a long-distance rigid support structure, and forming a dual support effect in conjunction with a flexible support structure.

[0038] like Figure 5As shown, the bent pipe 320 is arranged in upper and lower layers, and a clamp ring 331 is provided between the two bent pipes 320 for clamping the cable 310, and an anchor cable 330 is installed on the outer side of the clamp ring 331 to connect the ground to form tension on the upper and lower layers of the cable 310, which is used to tighten and fix the circular cable 310 after the photovoltaic panel 110 is laid.

[0039] like Figure 6 and Figure 7 As shown, the transmission unit 500 on the inner side of the upper end of the fixed column 210 is provided with a first bracket 510 and a second bracket 530 divided into front and rear parts, both of which are provided with holes inside for rotating the support rod connected to the end of the pressure wheel 520, and the hole inside the upper end of the second bracket 530 is a through-type limiting hole 531, which is used to expose the positioning rod 522 at the end of the upper pressure wheel 520. The positioning rod 522 is an extended support rod, one end of which is provided with a slot 5221, which generates rotation after docking with an external active rotation drive device.

[0040] like Figure 6 As shown, a gear 521 is provided on the outer side of one end of the pressure wheel 520 adjacent to the second bracket 530, and adjacent gears 521 are meshed and connected with each other. When the upper pressure wheel 520 rotates, the two meshed gears 521 cause the two pressure wheels 520 to rotate in opposite directions at the same time, and the squeezing force and friction force on the cable 310 are combined to make it move, thereby achieving the effect of moving the photovoltaic panel 110 for laying.

[0041] As shown Figure 5 and Figure 6 As shown, side holes 421 are provided inside the fixing seat 410, inside the front and rear ends of the support 420, and inside the connecting frame 220 and are aligned with each other for docking with the connecting rod 432 to form a connection and support. A guide edge 4321 is provided at one end of the connecting rod 432, which automatically aligns the axis when contacting the side hole 421, so as to promote the alignment of the fixing seat 410 and the support 420.

[0042] like Figure 1 - Figure 4 As shown, a guide rod 431 is rotatably installed in the middle of the slide 430, and a screw 433 is provided at one end thereof and is located between adjacent connecting rods 432. Screw holes 422 are provided in the center of the support 420 and the center of the connecting frame 220 located on the right and are aligned with each other for docking the screw 433. After this arrangement, any group of fixed seats 410 and supports 420 can be separated by the slide 430, so that the upper photovoltaic panel 110 can be disassembled separately without affecting the adjacent photovoltaic panels 110, which is convenient for subsequent maintenance and replacement.

[0043] It can be understood that the present invention can transport photovoltaic panels 110 from both ends to the middle for laying construction, which reduces the difficulty of work while the photovoltaic panels 110 are laid neatly, and the bottoms of adjacent photovoltaic panels 110 form a rigid connection, combined with the cables to form a dual support effect of rigidity and flexibility, resisting sagging and wind to reduce the failure rate.
