[0037] Another core of the present utility model lies in disclosing a photovoltaic system including the above flexible tracking photovoltaic bracket.

[0038] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0039] As Figure 1 - Figure 2 shown, the embodiment of the present utility model discloses a flexible tracking photovoltaic bracket, including a main cable 100, a bracket 400, a rigid support 200, and a wind-resistant cable 300.

[0040] Specifically, the support 400 supports the main cable 100. The main cable 100 is arranged on the support 400. The main cable 100 includes at least two parallelly arranged ones. The rigid support member 200 is arranged between multiple main cables 100 and sequentially connects multiple main cables 100. The rigid support member 200 includes a plurality of spaced ones. The photovoltaic module 700 is arranged on the rigid support member 200. The rigid support member 200 is a rigid member, which can be a support rod or a support plate, and is not specifically limited as long as it can support the photovoltaic module 700. According to the number of photovoltaic modules 700, a corresponding number of rigid support members 200 are set so that the photovoltaic modules 700 are arranged in an array.

[0041] The wind-resistant cable 300 includes a wind-resistant horizontal cable 310. The wind-resistant horizontal cable 310 is respectively connected to the support 400 and the main cable 100 and is tightened with the main cable 100 to form an inverted arch shape. The inverted arch structure has strong wind resistance and can effectively disperse the wind force and reduce the influence of the sharp load on the photovoltaic module 700.

[0042] In the flexible tracking photovoltaic support disclosed in the embodiment of the present invention, the wind-resistant horizontal cable 310 is tightened with the main cable 100 to form an inverted arch structure, which has strong wind resistance, can improve the overall wind resistance of the system, can reduce the risk of the photovoltaic module 700 having hidden cracks, and ensure the stable operation of the photovoltaic module 700.

[0043] As Figure 3 shown, in some specific embodiments, the wind-resistant cable 300 further includes a wind-resistant inclined cable 320. One end of the wind-resistant inclined cable 320 is connected to the support 400, and the other end is connected to the ground foundation. The connection with the ground foundation can be in a fixed connection manner or a hinged connection manner. The setting of the wind-resistant inclined cable 320 can further improve the wind resistance of the flexible tracking photovoltaic support. It should be noted that the specific number of the wind-resistant inclined cables 320 is not limited. It can be only arranged on the support 400 located at the end of the main cable 100, or on other supports 400. Preferably, the wind-resistant inclined cables 320 are arranged on the supports 400 located at both ends of the main cable 100, and at least two wind-resistant inclined cables 320 are arranged on each end support 400.

[0044] It should be noted that the wind-resistant horizontal cable 310 and the main cable 100 form an inverted arch structure, and the span of the wind-resistant horizontal cable 310 can be specifically selected according to the actual situation.

[0045] In some specific embodiments, such as Figure 3As shown in the figure, the main cable 100 includes a first main cable 110 and a second main cable 120 arranged in parallel. The rigid support members 200 are disposed between the first main cable 110 and the second main cable 120 and are spaced apart. The spacing between adjacent two rigid support members 200 needs to ensure that it does not affect the installation of the photovoltaic module 700. As Figure 2 As shown in the figure, the first end of the rigid support member 200 is connected to the first main cable 110, and the second end is connected to the second main cable 120. Preferably, the extending direction of the rigid support member 200 is perpendicular to the extending direction of the main cable 100. In the figure, two sets of flexible tracking photovoltaic brackets are shown as an example for illustration.

[0046] As Figure 1 - Figure 2 As shown in the figure, in some specific embodiments, the wind-resistant cross cables 310 include a first wind-resistant cross cable 311 and a second wind-resistant cross cable 312. The first wind-resistant cross cable 311 is disposed below the first main cable 110 and is connected to the first main cable 110. The second wind-resistant cross cable 312 is disposed below the second main cable 120 and is connected to the second main cable 120. The settings of the first wind-resistant cross cable 311 and the second wind-resistant cross cable 312 can improve the wind resistance of the flexible tracking photovoltaic bracket.

[0047] Specifically, the first wind-resistant cross cable 311 is connected to the first main cable 110 through the first vertical connecting member 500, and the second wind-resistant cross cable 312 is connected to the second main cable 120 through the second vertical connecting member 600. Both the first vertical connecting member 500 and the second vertical connecting member 600 include a plurality of spaced-apart ones, and the specific number of settings is determined according to actual needs. The settings of the first vertical connecting member 500 and the second vertical connecting member 600 can improve the bearing capacity and anti-deformation ability of the flexible tracking photovoltaic bracket.

[0048] It should be noted that the first vertical connecting member 500 can be selected as a rigid connecting member or a flexible connecting member, and the second vertical connecting member 500 can be selected as a rigid connecting member or a flexible connecting member. Preferably, the types of both are the same type.

[0049] As Figure 1 As shown in the figure, for the flexible tracking photovoltaic bracket disclosed in the embodiment of the present invention, the bracket 400 includes a cross beam 410 and a column 420. Both the cross beam 410 and the column 420 can be provided as one. The middle of the cross beam 410 is connected to the column 420. The cross beam 410 and the column 420 can also be respectively provided as two. The two ends of one cross beam 410 are respectively connected to the lower ends of the two columns 420, and the two ends of the other cross beam 410 are respectively connected to the upper ends of the two columns 420, so that the overall bracket 400 is in a rectangular structure. This arrangement can improve the structural stability of the bracket 400. Among them, the main cable 100 is connected to the cross beam 410, and the wind-resistant cross cable 320 is connected to the column 420.

[0050] In some specific embodiments, the flexible tracking photovoltaic bracket also includes a driving device, which is transmission-connected to the rigid support member 200 to drive the photovoltaic assembly 700 to rotate, so that the photovoltaic assembly 700 rotates to adapt to the solar altitude angle and increase the illumination time of the photovoltaic assembly 700, thereby improving the photovoltaic power generation efficiency. There are multiple setting schemes for the driving device, which are not specifically limited here.

[0051] In addition, the embodiment of the present invention also discloses a photovoltaic system, including the above-mentioned flexible tracking photovoltaic bracket, and therefore has all the technical effects of the above-mentioned flexible tracking photovoltaic bracket, which will not be repeated here.
