For those skilled in the art, the specific meanings of these terms in this utility model can be understood according to specific circumstances.

[0032] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0033] See also Figure 1 The embodiment of the present application provides a self-balancing photovoltaic bracket, including a central column 1, side columns 2 and a flexible support net 3. Multiple side columns 2 are arranged around the central column 1 to form a polygon or a circle. The flexible support net 3 includes radial flexible cables 31, annular supports 32 and reinforced flexible cables 33. Radial flexible cables 31 are connected between the central column 1 and each side column 2; along the circumferential direction of the central column 1, the annular supports 32 are arranged around multiple radial flexible cables 31, and the radial flexible cables 31 and the annular supports 32 form a mesh structure, which is used to support photovoltaic modules 30; the reinforced flexible cables 33 are respectively connected to the side columns 2 and the radial flexible cables 31.

[0034] In practical applications, the central column 1 and the side column 2 are used as the main vertical force-bearing components, and multiple side columns 2 are connected in sequence to form an integral annular bracket. The annular bracket can be polygonal or circular. The annular bracket can evenly distribute stress on the structure, reduce local pressure concentration, and is suitable for soft foundations. It reduces the impact of uneven foundation settlement. The annular bracket can also resist strong winds on the sea surface and reduce shaking caused by wave movement. The central column 1 is located at the center of the annular bracket to enhance the vertical rigidity of the bracket. The radial flexible cable 31 and the annular support 32 form a mesh structure, which is used to support the photovoltaic module 30 for installation of the photovoltaic module 30. At the same time, the flexible support net 3 also includes a reinforcing flexible cable 33, which is connected to the side column 2 and the radial flexible cable 31 respectively, to tighten the radial flexible cable 31, to prevent the mesh structure composed of the radial flexible cable 31 and the annular support 32 from shaking due to wind load, thereby preventing the photovoltaic module 30 from shaking up and down and causing unstable connection, reducing the impact of wind load on the flexible support net 3, and improving the stability of the photovoltaic bracket.

[0035] It should be noted that the annular support member 32 may be a flexible cable or a rigid purlin.

[0036] See also Figure 2 The self-balancing photovoltaic bracket also includes a connector 4. The radial flexible cable 31 is connected with multiple connectors 4 along its extension direction. Along the extension direction of the radial flexible cable 31, multiple annular support members 32 are connected to the multiple connectors 4 one by one; along the circumferential direction of the central column 1, the annular support members 32 are sequentially passed through the connectors 4 in the multiple radial flexible cables 31.

[0037] Specifically, each radial flexible cable 31 is connected with a plurality of connectors 4 along its extension direction, and an annular support 32 passes through the connectors 4 in the plurality of radial flexible cables 31 respectively to form a complete ring; the plurality of annular support 32 is arranged in the same manner along the extension direction of the radial flexible cable 31 to form a plurality of annular structures; thus, the plurality of annular support 32 and the plurality of radial flexible cables 31 form a mesh structure. The connector 4 mainly serves to fix the annular support 32 and the radial flexible cable 31 together, and the annular support 32 and the radial flexible cable 31 can be separated by disassembling the connector 4, which is beneficial to the construction of the operator in actual engineering, and is also beneficial to the later maintenance and replacement.

[0038] See also Figure 3 The above-mentioned connecting member 4 includes a fixing splint 41 and a fixing member 42. The two fixing splints 41 are respectively squeezed on the radial flexible cable 31 from opposite sides, and the fixing members 42 are respectively connected to the two fixing splints 41 to fix the fixing splints 41 and the radial flexible cable 31; the fixing splint 41 is provided with a through hole 43, and the annular support member 32 passes through the through hole 43.

[0039] In actual application, the fixing member 42 fixes the two fixing clamps 41 on the radial flexible cable 31. The two fixing clamps 41 squeeze the radial flexible cable 31 from opposite sides, and the friction force prevents the fixing clamps 41 from moving on the radial flexible cable 31. The fixing clamps 41 are provided with through holes 43, and the through holes 43 are used for the annular support member 32 to pass through, so as to realize the connection between the annular support member 32 and the radial flexible cable 31.

[0040] It is understandable that the number of the through-hole 43 may be one or more, and the plurality of through-holes 43 may be respectively provided for the plurality of annular support members 32 to pass through, that is, the annular support members 32 may adopt a multi-row or multi-layer structure to improve the supporting effect of the flexible support net 3. The fixing member 42 may adopt a screw or a bolt.

[0041] See again Figure 3 The connecting member 4 includes an extrusion member 44 , which is sleeved on the outer circumference of the radial flexible cable 31 , and two fixing clamps 41 are respectively pressed on the extrusion member 44 from opposite sides to fix the extrusion member 44 and the radial flexible cable 31 .

[0042] The extrusion piece 44 is sleeved on the outer circumference of the radial flexible cable 31 and is used to extrude the radial flexible cable 31. The fixed clamp 41 is clamped on the extrusion piece 44 to increase the extrusion force between the extrusion piece 44 and the radial flexible cable 31, further preventing the extrusion piece 44 from moving on the radial flexible cable 31, and strengthening the connection stability between the connecting piece 4 and the radial flexible cable 31.

[0043] In one embodiment, see Figure 4 The extrusion piece 44 may include a plurality of extrusion portions 441 spaced apart along its circumference, wherein the plurality of extrusion portions 441 are circumferentially arranged to form an extrusion hole 442, and the radial flexible cable 31 passes through the extrusion hole 442. With this arrangement, when the fixing splint 41 presses the extrusion piece 44, the mutually spaced extrusion portions 441 have a better extrusion effect on the radial flexible cable 31, further enhancing the fixing ability of the connector 4.

[0044] See also Figure 6 The self-balancing photovoltaic bracket also includes a first fixing component 5, which includes a U-shaped member 51, an anti-detachment cover 52 and a first anchor 53. The first anchor 53 is sleeved on the outer periphery of the radial flexible cable 31, and the anti-detachment cover 52 is connected to the first anchor 53. One end of the U-shaped member 51 is connected to the central column 1, and the other end is connected to the anti-detachment cover 52.

[0045] In order to achieve the fixation of the radial flexible cable 31, the present application provides a first fixing component 5, which is used to fix the radial flexible cable 31 to the central column 1. Specifically, the first fixing component 5 includes a U-shaped part 51, an anti-detachment cover 52 and a first anchor 53. The first anchor 53 is sleeved and tightly embraced on the radial flexible cable 31. The anti-detachment cover 52 is connected to the first anchor 53. The U-shaped part 51 usually has an open end and a closed end. The open end of the U-shaped part 51 can be welded to the anti-detachment cover 52, and the closed end only needs to pass through the fixing hole of the central column 1 to achieve the fixed connection between the radial flexible cable 31 and the central column 1. With this arrangement, the structure is simpler and the construction is convenient in actual construction, which improves engineering efficiency.

[0046] See again Figure 6 More specifically, the anti-detachment cover 52 is detachably connected to the first anchor 53, and the anti-detachment cover 52 and the first anchor 53 can be threadedly connected. After long-term use, the operator can remove the anti-detachment cover 52 to release the fixed connection between the radial flexible cable 31 and the center column 1, which is convenient for the operator to replace and repair the radial flexible cable 31 and extend the service life of the photovoltaic bracket.

[0047] It is understandable that the anti-drop cover 52 and the first anchor 53 may also be connected in other ways, which is not limited in the present application.

[0048] See also Figure 7 The self-balancing photovoltaic bracket also includes a second fixing component 6, which includes an end plate 61, an anchor plate 62 and a second anchor 63. The end plate 61 is fixed to the top of the side column 2, the anchor plate 62 is connected to one side of the end plate 61, the radial flexible cable 31 passes through the anchor plate 62, the second anchor 63 is sleeved on the outer periphery of the radial flexible cable 31 and is located on the side of the anchor plate 62 away from the end plate 61, and the second anchor 63 is in contact with the anchor plate 62.

[0049] In practical applications, the first fixing assembly 5 is used to fix the radial flexible cable 31 on the central column 1, and the second fixing assembly 6 is used to fix the radial flexible cable 31 on the side column 2. Specifically, the second fixing assembly 6 includes an end plate 61, an anchor plate 62 and a second anchor 63. The end plate 61 and the second anchor 63 are respectively located on opposite sides of the anchor plate 62. The second anchor 63 is sleeved and tightly embraced on the radial flexible cable 31. The second anchor 63 and the anchor plate 62 are mainly used to lock the radial flexible cable 31. In engineering, the radial flexible cable 31 needs to be pre-tensioned. The tensioned radial flexible cable 31 can bear the load. In order to prevent the tensioned radial flexible cable 31 from retracting, the second anchor 63 is locked to the radial flexible cable 31, and the second anchor 63 is in contact with the anchor plate 62 to prevent the radial flexible cable 31 from slipping. The present application uses different fixing assemblies at both ends of the radial flexible cable 31, which is beneficial to the installation and disassembly of the radial flexible cable 31 on the one hand, and is beneficial to the tensioning process of the radial flexible cable 31 on the other hand, reducing the construction difficulty.

[0050] See also Figure 7 and Figure 8 , the opposite ends of the reinforced flexible cable 33 are connected with the first fixing assembly 5; the first anchor 53 is sleeved on the outer periphery of the reinforced flexible cable 33, the anti-detachment cover 52 is connected to the first anchor 53, one end of the U-shaped member 51 is connected to the anti-detachment cover 52, and the other end is connected to the connecting member 4 or the side column 2.

[0051] Different from the above-mentioned radial flexible cable 31, the opposite ends of the reinforced flexible cable 33 are fixed by the first fixing assembly 5, the first anchor 53 is sleeved and tightly embraced on the reinforced flexible cable 33, the anti-detachment cover 52 is threadedly connected to the first anchor 53, the open end of the U-shaped member 51 on one side of the reinforced flexible cable 33 is welded to the anti-detachment cover 52, and the closed end passes through the fixing hole of the side column 2 to complete the fixation of the reinforced flexible cable 33 to the side column 2, and the closed end of the U-shaped member 51 on the other side passes through the through hole 43 on the fixing clamp 41 of the connecting member 4 to complete the fixation of the reinforced flexible cable 33 to the connecting member 4, that is, the fixation of the radial flexible cable 31 and the annular flexible cable. With such a configuration, the present application can achieve the fixation of the radial flexible cable 31, the annular flexible cable and the reinforced flexible cable 33 through the connecting member 4, and the structure is simple and the operation is convenient.

[0052] See again Figure 7 The self-balancing photovoltaic bracket also includes a crossbeam 7, a cross portion 8, a first fixing portion 10 and a second fixing portion 20. The crossbeam 7 is connected between two adjacent side columns 2; the side column 2 is connected to the cross portion 8, the first fixing portion 10 is circumferentially connected to one end of the cross portion 8 close to the crossbeam 7, and the second fixing portion 20 is circumferentially connected to one end of the cross portion 8 close to the cross portion 8. The first fixing portion 10 is connected to the second fixing portion 20 to fix the crossbeam 7 and the side column 2.

[0053] In actual application, adjacent side columns 2 are connected by the cross beam 7 to form a complete annular bracket. Specifically, a cross portion 8 is connected to the side column 2, and the cross portion 8 extends in a direction close to the cross beam 7 and parallel to the cross beam 7, which is beneficial to the relative connection between the cross portion 8 and the cross beam 7. The first fixing portion 10 is annularly connected to the cross portion 8, and the first fixing portion 10 increases the connection area of ​​the cross portion 8. Similarly, the second fixing portion 20 is annularly connected to the cross beam 7, and the second fixing portion 20 increases the connection area of ​​the cross beam 7. The first fixing portion 10 and the second fixing portion 20 are relatively fixed together, and the connection area between the cross portion 8 and the cross beam 7 is increased by the first fixing portion 10 and the second fixing portion 20, thereby improving the connection stability between the two, thereby improving the stability of the bracket.

[0054] It is understandable that the first fixing portion 10 and the second fixing portion 20 may be connected together by welding or bolting, and the present application does not limit this.

[0055] See also Fig. 9 The embodiment of the present application also provides a photovoltaic device, including the above-mentioned self-balancing photovoltaic bracket and photovoltaic module 30, the photovoltaic module 30 is mounted on the self-balancing photovoltaic bracket, specifically, the photovoltaic module 30 is fixed on the annular support 32, and the photovoltaic module 30 is used to receive sunlight and convert it into electrical energy.

[0056] In practical applications, in order for the radial flexible cable 31 to bear the load of the photovoltaic module 30, it is necessary to apply pre-tension to the radial flexible cable 31 to make the entire structure rigid. The load of the photovoltaic module 30 is transmitted to the side column 2 and the beam 7 through the radial flexible cable 31, so that the beam 7 bears axial pressure; by arranging multiple side columns 2 in a ring around the central column 1, the structure is arranged into a polygon or a circle, so that a closed loop is formed between the beams 7, and the axial forces of the beams 7 are balanced with each other to achieve the self-balancing requirement of the structure; since the cable force of this photovoltaic bracket will not be transmitted to the foundation, compared with the traditional flexible photovoltaic bracket, the use of this device has lower requirements on the foundation, and the pre-tension balancing device can be eliminated, which expands the application range of flexible photovoltaics.

[0057] It should be noted that the number of self-balancing photovoltaic brackets can be one or more. When the number of self-balancing photovoltaic brackets is more than one, two adjacent self-balancing photovoltaic brackets share two adjacent side columns 2. Multiple self-balancing photovoltaic brackets can be used to assemble large-area photovoltaic modules 30, expand the installation range of photovoltaic modules 30, and two adjacent self-balancing photovoltaic brackets share two side columns 2, thereby enhancing the connection stability between the two self-balancing photovoltaic brackets and saving economic costs.

[0058] See also Fig.10 The photovoltaic device also includes a photovoltaic fixing component 40, which includes a fixing bolt 401, a clamping member 402 and a locking member 403. The locking member 403 is provided with a locking hole 4011, and the annular support member 32 passes through the locking hole 4011. The locking member 403 hugs the annular support member 32 to achieve the fixation of the locking member 403 and the annular support member 32; the clamping member 402 is used to press the photovoltaic component 30 against the locking member 403, and the fixing bolt 401 passes through the clamping member 402 and is fixedly connected with the locking member 403. The fixing bolt 401 fixes the clamping member 402 to the locking member 403 to achieve the effect of the clamping member 402 clamping the photovoltaic component 30. It also includes an adjusting bolt 404, and the locking piece 403 is also provided with a long adjusting hole 4012. The photovoltaic component 30 is also provided with a fixing hole. The adjusting bolt 404 passes through the fixing hole and is fixedly connected to the adjusting hole 4012 to fix the photovoltaic component 30 and the locking piece 403. At the same time, the position of the photovoltaic component 30 can be fine-tuned.

[0059] Different from the prior art, the embodiment of the present application provides a photovoltaic device and a self-balancing photovoltaic support thereof, and a photovoltaic module 30 is mounted on the self-balancing photovoltaic support. The self-balancing photovoltaic support includes a central column 1, a side column 2 and a flexible support net 3, a plurality of side columns 2 are arranged around the central column 1, and the flexible support net 3 includes radial flexible cables 31, annular supports 32 and reinforcing flexible cables 33. The central column 1 and each side column 2 are connected with radial flexible cables 31; along the circumferential direction of the central column 1, the annular supports 32 are arranged around the plurality of radial flexible cables 31, and the radial flexible cables 31 and the annular supports 32 form a mesh structure, which is used to support the photovoltaic module 30; the reinforcing flexible cables 33 are respectively connected to the side columns 2 and the radial flexible cables 31. Compared with the prior art, the flexible support net 3 of the present application also includes a reinforced flexible cable 33, which is respectively connected to the side column 2 and the radial flexible cable 31, so as to tighten the radial flexible cable 31, thereby preventing the mesh structure composed of the radial flexible cable 31 and the annular support member 32 from shaking due to wind load, thereby preventing the photovoltaic component 30 from shaking up and down and causing an unstable connection, reducing the impact of wind load on the flexible support net 3, and improving the stability of the photovoltaic bracket. In the photovoltaic equipment using the above-mentioned self-balancing photovoltaic bracket, the load of the photovoltaic module 30 is transmitted to the side column 2 and the beam 7 through the radial flexible cable 31, so that the beam 7 bears axial pressure; by arranging multiple side columns 2 in a ring around the central column 1, the structure is arranged into a polygon or a circle, so that a closed loop is formed between the beams 7, and the axial forces of the beams 7 are balanced with each other to achieve the self-balancing requirement of the structure; since the cable force of this photovoltaic bracket will not be transmitted to the foundation, compared with traditional flexible photovoltaic brackets, the use of this device has lower requirements on the foundation, and the pre-tension balancing device can be eliminated, thereby expanding the application range of flexible photovoltaics, and can be suitable for soft foundations or terrains with large wind loads, and fewer steel cables can be used to achieve good support, thereby improving the practicality of photovoltaic equipment and reducing construction costs.

[0060] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
