[0003] The existing flexible photovoltaic support system based on a single-layer cable system has been found to have shortcomings during use. First, for a single-layer double-row photovoltaic panel assembly, each row of photovoltaic panel assemblies needs to be supported by two suspension cables, and a double-row photovoltaic panel assembly requires a total of four suspension cables. In addition, each suspension cable needs to be provided with an independent support assembly at a certain distance, resulting in a large number of overall support component consumables and a high assembly cost of the flexible photovoltaic support system; second, for a single-layer double-row photovoltaic panel assembly, it cannot achieve automatic adjustment of the inclination angle of the photovoltaic panel assembly, affecting the photovoltaic power generation efficiency; third, the edge of the photovoltaic panel assembly is wrapped and fixed by an aluminum alloy frame to play an insulating and load-bearing role, and the bottom area of ​​the photovoltaic panel is covered by dust and gray water on the photovoltaic panel due to the aluminum alloy lower frame blocking it, which affects the power generation efficiency and may cause hot spot effect to damage the photovoltaic panel.

DETAILED DESCRIPTION

[0021] 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.

[0022] like Figure 1-Figure 6 As shown, this embodiment provides a three-cable two-longitudinal flexible photovoltaic support system, which includes a single-layer cable system, a photovoltaic panel assembly 3, a cross-row support 4, an end tracking support 5 and an intermediate support 6. The single-layer cable system is composed of two side suspension cables 1 and an intermediate suspension cable 2 arranged side by side; each side suspension cable 1 is installed with at least two photovoltaic power generation units, and each photovoltaic power generation unit includes a number of photovoltaic panel assemblies 3 arranged side by side; a number of cross-row support members 4 are installed on the intermediate suspension cable 2, and the cross-row support members 4 are used to connect two opposite photovoltaic panel assemblies 3; the outer ends of the side suspension cables 1 and the intermediate suspension cables 2 are supported by the end tracking support 5, and the cable bodies of the side suspension cables 1 and the intermediate suspension cables 2 located between two adjacent photovoltaic power generation units are supported by the intermediate support 6.

[0023] like Figure 2 As shown, the end tracking bracket 5 includes an end column 501, a movable horizontal axis 502, an end beam 503, a cantilever 504 and a driving push rod 505. The top of the end column 501 is movably supported by the movable horizontal axis 502, the inner end of the movable horizontal axis 502 is fixed with an end beam 503 for installing a single-layer cable system, the outer side of the movable horizontal axis 502 is vertically fixed with a cantilever 504, and a driving push rod 505 for adjusting the inclination angle of the end beam 503 is installed between the cantilever 504 and the column 501, and the two ends of the driving push rod 505 are respectively connected to the cantilever 504 and the column 501 by a hinged manner.

[0024] The working principle of the end tracking bracket 5 is as follows: when it is necessary to adjust the inclination angle of the end beam 503 (that is, the inclination angle of the photovoltaic panel assembly 3), the driving push rod 505 is started, and the distance between the first hinge point (that is, the hinge point between the cantilever 504 and the driving push rod 505) and the second hinge point (that is, the hinge point between the column 501 and the driving push rod 505) is changed, so that the movable horizontal axis 502 and the end beam 503 rotate synchronously to achieve inclination adjustment.

[0025] like Figure 5As shown, the intermediate support 6 includes an intermediate column 601 and an intermediate beam tube 602. The upper end of the intermediate column 601 is provided with a boss 603 extending into the intermediate beam tube 602. Three cable sleeves 604 are fixed in the inner cavity of the intermediate beam tube 602 for the single-layer cable system to pass through. The boss 603 is provided with a support bearing that cooperates with the intermediate cable sleeve 604. The bottom plate of the intermediate beam tube 602 is provided with a strip hole that facilitates its own rotation around the axis of the support bearing. The width of the strip hole cooperates with the thickness of the boss 603.

[0026] The working principle of the middle bracket 6 is as follows: when the end tracking bracket 5 drives the end beam 503 to adjust the inclination angle, the end beam 503 can drive the middle beam tube 602 to rotate around the axis of the support bearing through the single-layer cable system.

[0027] In this embodiment, when the number of photovoltaic power generation units is large, in order to ensure the synchronization of the tilt adjustment of the photovoltaic panel assembly 3, part of the intermediate bracket 6 can be replaced by an active driving mechanism similar to the end tracking bracket 5.

[0028] like Figure 7-Figure 9 As shown, the cross-row support member 4 is composed of two opposite support members connected by fasteners 405, and the support member is composed of a longitudinal beam 401, a clamping half pipe 402, an end plate 403 and a dust collector 404. One end of the longitudinal beam 401 is connected to the clamping half pipe 402, and both ends of the clamping half pipe 402 are provided with end plates 403.

[0030] The working principle of the ash cleaner 404 is as follows: the gap between the bending strip of the upper clamping plate 404a and the outer frame 301 of the photovoltaic panel assembly 3 is a gradually opening gap, which has the function of using the capillary principle to guide water, thereby forming a siphon effect, which is convenient for quickly discharging the gray water accumulated on the photovoltaic panel. The water suction port 404e is an inverted U-shaped opening, which is used to assist the ash cleaner 404 to guide rainwater or gray water mixture into it. The concave support portion 404d is used to support the optimal gap between the ash cleaner plate wall and the outer frame 301 of the photovoltaic panel assembly 3 to form a drainage channel. The bottom position of the concave support portion 404d is tightly fitted with the outer frame 301 of the photovoltaic panel assembly 3. Multiple drainage channels are formed between the two sides of the concave support portion 404d on the inner side of the ash cleaner 404 and the outer frame 301 of the photovoltaic panel assembly 3 to achieve the drainage function. The connecting plate portion 404b is provided with a drainage hole 404g, which is used to suck the water into the ash cleaner 404. The gray water in the part is discharged; a plurality of self-cleaning flushing holes 404f are evenly arranged on the upper clamping plate portion 404a, and the self-cleaning flushing holes 404f are used to provide a channel for rainwater to impact foreign objects inside the ash cleaner 404. When it rains, raindrops can frequently pass through the self-cleaning flushing holes 404f to impact the inside of the gap of the ash cleaner 404, driving the foreign objects in the gap of the drainage channel to move downward and be discharged from the ash cleaner 404. A clamping structure is provided at the ends of the upper clamping plate portion 404a and the lower clamping plate portion 404c, and the clamping structure is used to fix the ash cleaner.

[0032] like Fig.11 As shown, the two outermost photovoltaic panel assemblies 3 in the same photovoltaic power generation unit are connected to the side suspension cable 1 through a first mounting member 7, and a second mounting member 8 connected to the side suspension cable 1 is installed between two adjacent photovoltaic panel assemblies 3 in the same photovoltaic power generation unit.

[0033] like Fig.12As shown, the photovoltaic panel assembly 3 includes a photovoltaic panel and an outer frame 301 serving as its mounting carrier. The outer frame 301 is generally a rectangular structure, and the bottom end of the outer frame 301 extends inward to form a rectangular frame edge 302. Two mounting holes 303 are symmetrically provided in the middle of the rectangular frame edge 302 for facilitating the installation of the first mounting member 7 or the second mounting member 8.

[0034] like Fig.13 and Fig.14 As shown, the first mounting member 7 includes a first upper piece 701 and a first lower piece 702, and the first upper piece 701 and the first lower piece 702 together form a first cable clamping groove 703 for clamping the side cable 1, and the first upper piece 701 and the first lower piece 702 are provided with a first rivet hole for installing a first rivet 704, and the first upper piece 701 and the first lower piece 702 clamped on the outside of the side cable 1 are fixedly connected to the rectangular frame edge 302 of the photovoltaic panel assembly 3 by riveting.

The cross-row support 4 can be used to connect two opposite photovoltaic panel assemblies 3 in different rows, and the end tracking bracket 5 and the middle bracket 6 are used to meet the support requirements of the single-layer cable system. In this way, only three cables are needed to realize the assembly of the single-layer double-row photovoltaic panel assembly, reducing the material consumption of the overall supporting components and reducing the assembly cost of the flexible photovoltaic support system.

[0038] For the single-layer double-row photovoltaic panel assembly 3, the end tracking bracket 5 and the middle bracket 6 are used to drive the single-layer cable system to flip, thereby realizing automatic adjustment of the inclination angle of the photovoltaic panel assembly 3 to ensure the efficiency of photovoltaic power generation.

[0039] The connecting parts at both ends of the cross-row support members 4 are set as dust cleaners 404. The dust cleaners 404 can cooperate with the adjustable inclination angle of the photovoltaic panel assembly 3 to solve the problem of strip-shaped dust accumulation at the bottom of the photovoltaic panel assembly 3 that partially blocks sunlight, avoid the conduction of the bypass diode in the photovoltaic panel, and then eliminate the hot spot effect of the photovoltaic panel, thereby greatly improving the power generation.
