Description

Technical Field

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

[0002] A flexible photovoltaic support is a large-span photovoltaic module support structure with both ends fixed, designed based on a tension structure system, and using cables as component support members; the wide application of flexible photovoltaic supports mainly benefits from their ability to solve problems in large-slope mountain projects in the southwest, Yunnan, Guizhou, etc., and insufficient photovoltaic land area in conventional terrains, and can also be used in projects combining photovoltaic with other industries, such as fish-light complementary.

[0003] Currently, in the actual application of flexible photovoltaic supports, it is found that due to the installation of photovoltaic panels on the flexible photovoltaic support in high-altitude areas and the characteristics of large spans, the installation of photovoltaic panels requires workers to operate in multiple high-altitude areas. Affected by the sag and sway of the cables, etc., the installation difficulty in high-altitude operations is greater, posing great safety hazards, and at the same time, the photovoltaic laying efficiency cannot be guaranteed.

[0004] To solve the above problems, a large-span flexible photovoltaic support system is proposed in this application. 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] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0007] A large-span flexible photovoltaic support system includes a photovoltaic module and the photovoltaic panels inside it, an end-point fixing unit and the fixing columns inside it, and a flexible support unit and the cables inside it. The photovoltaic module is located above the flexible support unit between the left and right adjacent end-point fixing units;

[0008] The cable passes through a bent pipe outside the upper end of the fixing column to form a loop. There are two upper and lower pressing wheels inside the upper end of the fixing column for squeezing the cable and driving its movement. The photovoltaic panel is fixed above the cable through a fixing clip below, forming a mobile support structure and a mobile laying function;

[0009] A rigid support unit is located in the lower area of the photovoltaic panel, including a fixing base and a support. They are respectively located at the left and right ends of the photovoltaic panel. There is a sliding frame on the right side of the support, and the fixing base and the support are connected through a connecting rod inside it, so that adjacent photovoltaic panels are aligned to achieve a neat laying effect;

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

[0011] Advantages of the present invention:

[0012] Through the loop arrangement of the cable and the extrusion of adjacent pressure wheels, after the photovoltaic panel is installed on the cable, it can be directly externally connected to a driving device to drive the cable to transmit, so as to drive the photovoltaic panel to move to the area between the two fixed columns. Workers do not need to perform high-altitude operations in multiple areas, and the photovoltaic panel can also be laid in the high-altitude area to form a movable flexible support structure, which not only reduces the construction difficulty, eliminates potential safety hazards, but also does not need to worry about the shaking and sagging of the cable affecting the laying operation;

[0013] Before transmitting the photovoltaic panel, the present invention first connects the adjacent support seats and the sliding frames through the connecting rods, so that the adjacent photovoltaic panels are neatly arranged for transmission. After this arrangement, only by aligning the photovoltaic panels in the area where the fixed columns are located can the laying neatness of the photovoltaic panels in the area between the two fixed columns be ensured;

[0014] In addition, after the support seat and the sliding frame of each group are connected, a rigid connection is formed. Then, the connecting rods connect the connecting frames at both ends with the support seat and the sliding frame respectively, which can form a rigid support structure for the photovoltaic panels in the high-altitude area, so that the flexible support and the rigid support are combined, which not only improves the installation stability, but also prevents the sagging and shaking of the cable, prolongs the support time and reduces the failure rate.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] As Figure 1 - Figure 6As shown in the figure, the present invention provides a large-span flexible photovoltaic support system, which includes a photovoltaic module 100 and the photovoltaic panels 110 inside it, an end fixing unit 200 and the fixing columns 210 inside it, and a flexible support unit 300 and the cables 310 inside it. The photovoltaic module 100 is located above the flexible support unit 300 in the middle of the left and right adjacent end fixing units 200;

[0034] The cable 310 passes through the elbow 320 on the outer side of the upper end of the fixing column 210 and forms a loop between the left and right adjacent fixing columns 210. There are two upper and lower pressing wheels 520 on the inner side of the upper end of the fixing column 210 for pressing the lower cable 310. Through an externally connected rotary drive device, the cable 310 is driven to move by means of friction. Before that, the photovoltaic panel 110 is pre-fixed above the cable 310 through the fixing clip 120 below, thus forming a mobile support structure and a mobile laying function, realizing long-distance laying without workers climbing heights in multiple places;

[0035] The rigid support unit 400 includes a fixed seat 410 and a support 420, which are respectively located at the left and right ends below the photovoltaic panel 110. There is a carriage 430 on the right side of the support 420, and the support 420 and the carriage 430 are connected through the connecting rod 432 inside it, so that the adjacent photovoltaic panels 110 are aligned. Furthermore, when moving, the two photovoltaic panels 110 remain aligned, thus achieving the effect of neat laying, reducing the working difficulty and having strong practicability;

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

[0037] This embodiment provides a double support structure for a photovoltaic module. First, the photovoltaic panel 110 is fixed above the upper cable 310 through the fixing clip 120. Then, when installing another photovoltaic panel 110, the support 420 and the carriage 430 are connected in series through the connecting rod 432, so that the adjacent photovoltaic panels 110 are aligned. Subsequently, an external device drives the pressing wheel 520 to rotate, and the cable 310 is moved by the extrusion force to drive the photovoltaic panel 110 to move towards the fixing column 210 at the other end. Through this, a mobile laying operation can be formed, and long-distance photovoltaic laying construction can be realized without workers climbing heights in multiple areas; in addition, after the photovoltaic panels 110 are laid, the support 420 and the carriage 430 are respectively connected with the connecting frame 220 through the connecting rod 432 again, thus forming a long-distance rigid support structure, which cooperates with the flexible support structure to form a double support effect.

[0038] As Figure 5As shown, the elbow pipe 320 is arranged in upper and lower layers, and a clamping ring 331 is provided between the two elbow pipes 320 for clamping the cable 310. An anchor cable 330 is installed outside the clamping ring 331 to connect to the ground to form a tensile force on the upper and lower layers of the cable 310, which is used to tighten and fix the loop-shaped cable 310 after the photovoltaic panel 110 is laid.

[0039] As Figure 6 and Figure 7 As shown, in the transmission unit 500 inside the upper end of the fixed column 210, there are a first bracket 510 and a second bracket 530 partitioned front and back, and holes are opened inside both of them for rotatably connecting the support rods at the ends of the pressing wheels 520. The hole inside the upper end of the second bracket 530 is a through-type limiting hole 531 for exposing the positioning rod 522 at the end of the upper pressing wheel 520. The positioning rod 522 is an extended support rod, and a clamping groove 5221 is opened at one end of it, which rotates after being connected to an external active rotary driving device.

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

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

[0042] As Figure 1 - Figure 4 As shown, a guide rod 431 is rotatably installed in the middle of the carriage 430, and a screw rod 433 is provided at one end of it between the adjacent connecting rods 432. Threaded holes 422 are opened at the center of the support 420 and at the center of the connecting frame 220 on the right and are aligned with each other for docking the screw rod 433. After this arrangement, any group of the fixed seat 410 and the support 420 can be separated through the carriage 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 and other processing and use.

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