[0030] 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, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. 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.

[0031] like Figures 1 to 5As shown, an embodiment of the present invention provides a flexible photovoltaic bracket, which includes a first outer cable unit 10, a second outer cable unit 20 and an inner cable unit 30. The first outer cable unit 10 includes a first rope pair 11 and a first grounding frame 12. The first grounding frame 12 is arranged in the middle of the first rope pair 11, and both ends of the first rope pair 11 are grounded. The second outer cable unit 20 includes a second rope pair 21 and a second grounding frame 22. The second rope pair 21 is arranged in parallel with the first rope pair 11, and the second grounding frame 22 is arranged in the middle of the second rope pair 21. Both ends of the second rope pair 21 are grounded. The inner cable unit 30 includes a third rope pair 31 and a supporting rope 32. The third rope pair 31 is arranged in parallel with the first rope pair 11, and the third rope pair 31 is located between the first outer cable unit 10 and the second outer cable unit 20. Both ends of the supporting rope 32 are connected to the first grounding frame 12 and the second grounding frame 22 respectively, and the middle of the third rope pair 31 is supported on the supporting rope 32.

[0032] The flexible photovoltaic bracket provided in this embodiment includes a first outer cable unit 10, a second outer cable unit 20 and an inner cable unit 30. The applicant has found that during the use of the flexible photovoltaic bracket, the first outer cable unit 10 and the second outer cable unit 20 can partially block the wind blowing toward the inner cable unit 30 to weaken the wind load received by the inner cable unit 30, so that the wind load received by the inner cable unit 30 is less than the wind load received by the outer cable unit. By connecting the two ends of the support cable 32 to the first grounding frame 12 and the second grounding frame 22 respectively, the inner cable unit 30 uses the support cable 32 to support the third rope pair 31, the first outer cable unit 10 uses the first grounding frame 12 to support the first rope pair 11, and the second outer cable unit 20 uses the second grounding frame 22 to support the second rope pair 21, so that the inner cable unit 30 has a larger grounding support span than the first outer cable unit 10 and the second outer cable unit 20, and the inner cable unit 30 can save the number of grounding support components compared with the first outer cable unit 10 and the second outer cable unit 20, reduce the support cost, and improve the economy of the flexible photovoltaic bracket without affecting the wind resistance of the flexible photovoltaic bracket.

[0033] In this embodiment, the first rope pair 11 includes a first connecting transverse plate 112 and two first ropes 111 arranged in parallel, the first connecting transverse plate 112 includes two first buckling plates, the two first buckling plates are buckled on the two first ropes 111 and connected by a first fastener, the second rope pair 21 includes a second connecting transverse plate 212 and two second ropes 211 arranged in parallel, the second connecting transverse plate 212 includes two second buckling plates, the two second buckling plates are buckled on the two second ropes 211 and connected by a second fastener, the third rope pair 31 includes a third connecting transverse plate 312 and two third ropes 311 arranged in parallel, the third connecting transverse plate 312 includes two third buckling plates, the two third buckling plates are buckled on the two third ropes 311 and connected by a third fastener.

[0034] like Figure 5 As shown, the flexible photovoltaic support also includes a tensioning member 40, which is movably disposed on the first grounding frame 12 and / or the second grounding frame 22. When the tensioning member 40 is movable, it can push the support cable 32 to adjust the tension of the support cable 32. During the use of the flexible photovoltaic support, the support cable 32 is pushed by the movable tensioning member 40, so that the support cable 32 is kept in a tensioned state, thereby improving the support effect of the support cable 32 on the third rope pair 31.

[0035] like Figure 5 As shown, the tensioning member 40 includes a screw rod 41, a slider 42 and an extrusion plate 43. The extension direction of the screw rod 41 is set at an angle to the extension direction of the support cable 32. The screw rod 41 is rotatably set on the first grounding frame 12 around its axis. The first grounding frame 12 is provided with a slide groove 121 extending along the axial direction of the screw rod 41. The slider 42 is movably set in the slide groove 121 along the extension direction of the slide groove 121. The screw rod 41 and the slider 42 are threadedly matched. The first grounding frame 12 is also provided with an extrusion channel 122. The extension direction of the extrusion channel 122 is set at an angle to the extension direction of the support cable 32. One end of the support cable 32 passes through the extrusion channel 122 and is connected to the first grounding frame 12. The slider 42 is connected to the extrusion plate 43 to drive the extrusion plate 43 to slide in the extrusion channel 122. The extrusion plate 43 abuts and cooperates with the support cable 32 in the extension direction of the extrusion channel 122. When the screw rod 41 rotates around its axis, the screw rod 41 and the slider 42 are threadedly engaged to drive the slider 42 to move along the extension direction of the slide groove 121, driving the extrusion plate 43 to move in the extrusion channel 122, so that the extrusion plate 43 is in abutment with the support cable 32, so that the support cable 32 remains tensioned.

[0036] In this embodiment, a hand wheel is provided at one end of the screw rod 41 away from the first grounding frame 12 to facilitate the rotation of the screw rod 41 .

[0037] like Figures 2 to 4As shown, the support rope 32 includes a rope body 321 and a support frame 322. The two ends of the rope body 321 are respectively connected to the first grounding frame 12 and the second grounding frame 22. The lower end of the support frame 322 is connected to the rope body 321. The upper end of the support frame 322 is connected to the middle of the third rope pair 31. The support rope 32 with the above structure is convenient for stably connecting the support rope 32 and the third rope pair 31.

[0038] like Figure 2 and Figure 3 As shown, the support frame 322 includes a first sleeve 3221, a second sleeve 3222 and a column 3223. The first sleeve 3221 is sleeved on the rope body 321 and connected to the rope body 321, the second sleeve 3222 is sleeved on the third rope pair 31 and connected to the third rope pair 31, the upper end of the column 3223 is connected to the first sleeve 3221, and the lower end of the column 3223 is connected to the second sleeve 3222. The support frame 322 with the above structure is convenient for quickly and stably connecting the support frame 322, the third rope pair 31 and the rope body 321, and the structure is simple.

[0039] like Figure 3 As shown, the first sleeve 3221 includes an externally threaded sleeve 32211, an elastic sleeve 32212 and an internally threaded sleeve 32213. The externally threaded sleeve 32211 is sleeved on the rope body 321, the elastic sleeve 32212 is sleeved on the rope body 321 and connected to the end of the externally threaded sleeve 32211, the inner hole of the internally threaded sleeve 32213 includes an extruded hole section and a threaded hole section, the aperture of the extruded hole section gradually decreases in the direction away from the externally threaded sleeve 32211, the extruded hole section is sleeved on the outside of the elastic sleeve 32212, the inner wall of the extruded hole section is slidably matched with the outer wall of the elastic sleeve 32212, and the threaded hole section is sleeved on the outside of the externally threaded sleeve 32211 and threadedly matched with the externally threaded sleeve 32211. The external threaded sleeve 32211, the elastic sleeve 32212 and the internal threaded sleeve 32213 are sequentially sleeved on the rope body 321. After the external threaded sleeve 32211 moves to the bottom of the third rope 311, the internal threaded sleeve 32213 is rotated, and the threaded hole section is threadedly matched with the external threaded sleeve 32211, so that the extrusion hole section moves relative to the elastic sleeve 32212 toward the direction close to the external threaded sleeve 32211, so that the elastic sleeve 32212 gradually hugs the third rope 311 under the extrusion action of the extrusion hole section.

[0040] Among them, the outer diameter of the elastic sleeve 32212 gradually decreases in the direction away from the external threaded sleeve 32211, thereby improving the sliding smoothness between the elastic sleeve 32212 and the extrusion hole section. A cross groove is provided at the end of the elastic sleeve 32212 facing away from the external threaded sleeve 32211 to divide the end of the elastic sleeve 32212 into four parts for easy deformation.

[0041] like Figure 2 As shown, the support frame 322 also includes a reinforcing rib 3224 disposed between the first sleeve 3221 and the column 3223 to improve the connection strength between the first sleeve 3221 and the column 3223 .

[0042] like Figure 3 As shown, the second sleeve 3222 includes a locking member 32221 and two hinge members 32222. The two hinge members 32222 have a locking state of being locked on the third rope pair 31 and an open state of being relatively opened. When the two hinge members 32222 are in the locking state, the locking member 32221 can connect the two hinge members 32222. The second sleeve 3222 with the above structure is configured to lock the two hinge members 32222 on the third rope pair 31 and connect the two hinge members 32222 using the locking member 32221, so that the two hinge members 32222 clamp the third rope pair 31, thereby fixing the axial position of the second sleeve 3222 on the third rope pair 31 and preventing the second sleeve 3222 from moving along the axial direction of the third rope pair 31.

[0043] Specifically, the support frame 322 includes two first sleeves 3221, two columns 3223 and two second sleeves 3222. The number of the support frames 322 corresponds to the number of the third rope pairs 31. The two first sleeves 3221 are respectively sleeved on the two third ropes 311 of the third rope pair 31, the two columns 3223 are arranged in a one-to-one correspondence with the two first sleeves 3221, and the two second sleeves 3222 are arranged in a one-to-one correspondence with the two first sleeves 3221.

[0044] like Figure 5 As shown, the support cable 32 further includes a first anchor plate 323 and a second anchor plate. The first end of the rope body 321 passes through the first grounding frame 12 and is connected to the first anchor plate 323. The second end of the rope body 321 passes through the second grounding frame 22 and is connected to the second anchor plate. The first anchor plate 323 is located on the side of the first grounding frame 12 away from the second grounding frame 22 and abuts against the first grounding frame 12. The second anchor plate is located on the side of the second grounding frame 22 away from the first grounding frame 12 and abuts against the second grounding frame 22. When the tensioning member 40 is used to push the support cable 32 to adjust the tension of the support cable 32, by providing the first anchor plate 323 at the first end of the rope body 321 and the second anchor plate at the second end of the rope body 321, the first anchor plate 323 can be used to abut against the first grounding frame 12, and the second anchor plate can be used to abut against the second grounding frame 22, so as to prevent the rope body 321 from slipping out of the first grounding frame 12 and the second grounding frame 22.

[0045] like Figure 1As shown, the flexible photovoltaic support also includes a grounding terminal 50, one end of the first rope pair 11 is provided with the grounding terminal 50, the grounding terminal 50 includes a grounding terminal column and an inclined cable 52, the end of the first rope pair 11 and the upper end of the inclined cable 52 are both connected to the upper end of the grounding terminal column, the inclined cable 52 is inclined in the direction away from the first rope pair 11 from top to bottom, and the lower end of the grounding terminal column and the lower end of the inclined cable 52 are both grounded. With the above-mentioned grounding terminal 50, since the inclined cable 52 is inclined in the direction away from the first rope pair 11 from top to bottom, during the use of the flexible photovoltaic support, it can reliably resist the wind force received by the first rope pair 11.

[0046] In this embodiment, two grounding end pieces 50 are respectively provided at both ends of the first rope pair 11 , and the grounding structures at both ends of the second rope pair 21 and the third rope pair 31 are the same as those of the first rope pair 11 .

[0047] In this embodiment, the grounding support span of the inner cable unit 30 is two to three times that of the first outer cable unit 10, and the grounding support span of the inner cable unit 30 is two to three times that of the second outer cable unit 20. Specifically, the grounding support span of the first outer cable unit 10 and the grounding support span of the second outer cable unit 20 are both between ten meters and twenty meters, the first outer cable unit 10 includes one or two first rope pairs 11, the second outer cable unit 20 includes one or two second rope pairs 21, the grounding support span of the inner cable unit 30 is between twenty meters and forty meters, the support cable 32 is located in the middle of the grounding support span of the inner cable unit 30, the first grounding frame 12 is located in the middle of the grounding support span of the first outer cable unit 10, and the second grounding frame 22 is located in the middle of the grounding support span of the second outer cable unit 20.

[0048] When there are two first outer cable units 10, the connection heights of the support cable 32 and the first grounding frames 12 of the two first outer cable units 10 are gradually reduced in the direction away from the third rope pair 31; when there are two second outer cable units 20, the connection heights of the support cable 32 and the second grounding frames 22 of the two second outer cable units 20 are gradually reduced in the direction away from the third rope pair 31.

[0049] Specifically, when designing a flexible photovoltaic bracket, the following steps are included:

[0050] (1) Calculate the basic load based on local meteorological parameters;

[0051] (2) calculating the wind load shielding effect of the first outer cable unit 10 and the second outer cable unit 20 on the inner cable unit 30 through numerical simulation CFD;

[0052] (3) According to the specifications, inclination angle and load model of the photovoltaic module 60, the economic span lengths of the first outer cable unit 10, the second outer cable unit 20 and the inner cable unit 30 are calculated respectively;

[0053] (4) Establishing a flexible photovoltaic bracket model, performing load verification calculations, and adjusting the span lengths and material cross-sectional specifications of the first outer cable unit 10, the second outer cable unit 20, and the inner cable unit 30 according to the calculation results until the overall economic efficiency is optimal;

[0054] (5) Make a scaled-down model of the flexible photovoltaic bracket and conduct wind tunnel test verification.

[0055] like Figures 1 to 5 As shown, another embodiment of the present invention provides a photovoltaic system, the photovoltaic system includes a photovoltaic assembly 60 and a flexible photovoltaic bracket, the photovoltaic assembly 60 is arranged on the first rope pair 11, the second rope pair 21 and the third rope pair 31 of the flexible photovoltaic bracket, and the flexible photovoltaic bracket is the flexible photovoltaic bracket provided above. The photovoltaic system provided by this embodiment is also applied, by connecting the two ends of the support rope 32 to the first grounding frame 12 and the second grounding frame 22 respectively, and using the support rope 32 to support the third rope pair 31, compared with the first outer rope unit 10 and the second outer rope unit 20, the grounding support span of the inner rope unit 30 can be increased, and the support rope 32 is used to support the third rope pair 31, compared with the first grounding frame 12 and the second grounding frame 22, The cost of supporting the third rope pair 31 can be reduced, and the economic efficiency of the photovoltaic system is improved without affecting the wind resistance of the flexible photovoltaic bracket.

[0056] By increasing the ground support span of the inner cable unit 30, when the total span of the inner cable unit 30 is greater than the total span of the first outer cable unit 10 and the total span of the second outer cable unit 20, the number of photovoltaic components 60 installed on the inner cable unit 30 can be increased.

[0057] Among them, the grounding support span refers to the distance between two adjacent grounding structures, and the total span refers to the distance between the two grounding structures set at both ends. Specifically, the grounding support span and the total span of the inner cable unit 30 are both the distances between the grounding settings at both ends. The total span of the first outer cable unit 10 refers to the distance between the grounding settings at both ends (the distance between the grounding end pieces 50 at both ends). The total span of the second outer cable unit 20 refers to the distance between the grounding settings at both ends. The grounding support span of the first outer cable unit 10 refers to the distance between two adjacent first grounding frames 12 or the distance between the grounding end piece 50 and the first grounding frame 12 adjacent to the grounding end piece 50. The grounding support span of the second outer cable unit 20 refers to the distance between two adjacent second grounding frames 22 or the distance between the grounding setting at one end of the second outer cable unit 20 and the adjacent second grounding frame 22.

[0058] like Figure 2 and Figure 3 As shown, the photovoltaic assembly 60 includes a photovoltaic panel 61, a mounting plate 62 and a fixing block 63. The lower surface of the mounting plate is provided with a first buckling groove, and the upper surface of the fixing block 63 is provided with a second buckling groove. The first buckling groove and the second buckling groove are buckled and connected to clamp the third rope 311, so that the mounting plate 62 is set on the third rope pair 31, and the photovoltaic panel 61 is installed on the upper surface of the mounting plate 62.
