In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0061] During the construction of a photovoltaic power station, it is necessary to first lay out photovoltaic brackets, and then build photovoltaic modules for photovoltaic power generation on the photovoltaic brackets. In the prior art, photovoltaic brackets usually use steel as the main material, and use the advantages of steel's high structural strength and hardness to support photovoltaic modules. However, photovoltaic brackets made of steel are all rigidly connected internally. During the actual construction of photovoltaic brackets and photovoltaic modules, it is necessary to adjust the inclination angle of the supporting surface of the photovoltaic bracket for supporting the photovoltaic modules, but the existing photovoltaic brackets cannot meet the angle adjustment requirements.

[0062] Embodiment 1

[0063] In order to solve the above problems, Figure 1 to Figure 4 As shown, this embodiment provides a photovoltaic bracket 1000. The photovoltaic bracket 1000 includes a fixing frame, a column 300, a diagonal bracing beam 400 and a three-way joint 500, wherein the photovoltaic assembly is fixed on the fixing frame, the column 300 and the diagonal bracing beam 400 are both configured to support the fixing frame, and the columns 300, the diagonal bracing beam 400 and the fixing frame are connected and fixed in pairs through the three-way joint 500, and the three-way joint 500 includes three branch joints, at least two of the three branch joints are pivotally fixed, and the column 300, the diagonal bracing beam 400 and the fixing frame arranged on the pivotally fixed branch joints can rotate along the pivot axis 540.

[0064] The photovoltaic bracket 1000 can achieve stable support for the photovoltaic assembly by setting up a fixing frame and fixing the photovoltaic assembly on the fixing frame; the fixing frame is supported by setting columns 300 and diagonal bracing beams 400, and a three-way joint 500 with three branch joints is set between the columns 300, the diagonal bracing beams 400 and the fixing frame to ensure that at least two of the three branch joints are pivotally fixed. By adjusting the rotation angle of the columns 300, the diagonal bracing beams 400 and the fixing frame arranged on the pivotally fixed branch joints, the relative rotation angle between the fixing frame and the installation base surface can be adjusted, and then the relative rotation angle between the photovoltaic assembly fixed on the fixing frame and the installation base surface can be adjusted, so as to meet the requirements of different fixing angles of the photovoltaic assembly and improve the installation efficiency of the photovoltaic assembly.

[0065] Specifically, the photovoltaic bracket 1000 includes a transverse beam 100 extending in the transverse direction and a longitudinal beam 200 extending in the longitudinal direction. The transverse beam 100 extending in the transverse direction and the longitudinal beam 200 extending in the longitudinal direction are interconnected and fixed to form a fixing frame, which has a simple structure, is easy to assemble, and can ensure the structural strength of the fixing frame.

[0066] As an optional solution, the column 300 includes a column body 310 and a base 320, wherein the column body 310 is connected to the diagonal bracing beam 400 and the fixing frame in pairs, the base 320 is fixed on the mounting base, and the column body 310 is fixed on the base 320. By configuring the column 300 as the base 320 fixed on the mounting base and the column body 310 arranged on the base 320, and by connecting and fixing the column body 310 to the diagonal bracing beam 400 and the fixing frame, the support stability of the column 300 to the fixing frame and the photovoltaic module can be improved.

[0067] In addition, in order to further improve the supporting effect of the fixing frame and the photovoltaic module, a plurality of groups of columns 300 and diagonal bracing beams 400 are arranged in the photovoltaic support 1000, with one column 300 and one diagonal bracing beam 400 as a group, and the plurality of groups of columns 300 and diagonal bracing beams 400 jointly support the fixing frame. Specifically, in the present embodiment, the fixing frame is rectangular, and four groups of columns 300 and diagonal bracing beams 400 are arranged in the photovoltaic support 1000, and the four groups of columns 300 and diagonal bracing beams 400 are respectively arranged at the four end points of the rectangular fixing frame to achieve stable support for the fixing frame. In other embodiments, in order to further facilitate the adjustment of the inclination angle of the fixing frame, the specific number of groups of columns 300 and diagonal bracing beams 400 can also be adjusted according to actual needs, and this embodiment does not make specific limitations.

[0068] In addition, if Figure 1As shown, since the photovoltaic bracket 1000 in this embodiment only has the need for angle adjustment along the left-right direction, the diagonal bracing beams 400 in this embodiment are all connected to the cross beam 100 in the fixing frame, and the rotation angle of the fixing member along the left-right direction is adjusted by adjusting the rotation angle between the column body 310, the diagonal bracing beam 400 and the cross beam 100. In other embodiments, one column 300 and two diagonal bracing beams 400 can also be used as a group, so that one of the two diagonal bracing beams 400 is connected to the column body 310 and the cross beam 100, and the other is connected to the column body 310 and the longitudinal beam 200, so as to meet the needs of adjusting the angle of the fixing frame along the left-right direction and along the front-back direction.

[0069] Combination Figure 2 to Figure 4 The specific structure of the three-way joint 500 is described. The three-way joint 500 includes a first branch joint 510, a second branch joint 520 and a third branch joint 530, wherein the first branch joint 510 is provided with a first fixing member 511, the second branch joint 520 is provided with a second fixing member 521, and the third branch joint 530 is provided with a third fixing member 531. The first branch joint 510, the second branch joint 520 and the third branch joint 530 are connected to each other, and at least two of the three are pivotally connected along the pivot axis 540. The first fixing member 511, the second fixing member 521 and the third fixing member 531 are respectively used to connect and fix any two of the three columns 300, the diagonal bracing beam 400 and the cross beam 100. By setting a first fixing member 511 on the first branch joint 510, a second fixing member 521 on the second branch joint 520, and a third fixing member 531 on the third branch joint 530, a stable connection between the column body 310, the diagonal bracing beam 400 and the cross beam 100 can be achieved by using the first fixing member 511, the second fixing member 521 and the third fixing member 531.

[0070] As an alternative, Figure 2 to Figure 4As shown, the first branch joint 510 and the second branch joint 520 are connected and fixed to each other, and the third branch joint 530 is pivoted with the first branch joint 510 and the second branch joint 520 that are connected and fixed together along the pivot axis 540, so as to achieve the effect that the first branch joint 510 and the second branch joint 520 rotate relative to the third branch joint 530 along the pivot axis 540. In other embodiments, according to actual needs, the first branch joint 510 and the third branch joint 530 can be connected and fixed, and the second branch joint 520 can be pivoted with the first branch joint 510 and the third branch joint 530 that are connected and fixed together along the pivot axis 540; or the second branch joint 520 and the third branch joint 530 can be connected and fixed, and the first branch joint 510 can be pivoted with the second branch joint 520 and the third branch joint 530 that are connected and fixed together along the pivot axis 540, which is not specifically limited in this embodiment. The first branch connector 510 , the second branch connector 520 and the third branch connector 530 are all pivotally connected along the pivot axis 540 .

[0071] In this embodiment, if Figure 2 to Figure 4 As shown, the use of a three-way joint 500 to connect the column body 310 and the crossbeam 100 is used as an example for explanation. The first branch joint 510 and the second branch joint 520 are only connected to each other but not pivoted, and the third branch joint 530 is pivoted to the first branch joint 510 and the second branch joint 520 fixed together through the pivot shaft 540. When it is necessary to adjust the adjustment angle of the fixing frame in the left and right direction, the first branch joint 510 and the second branch joint 520 are adjusted so that the first branch joint 510 and the second branch joint 520 rotate relative to the third branch joint 530 along the pivot shaft 540 to achieve the angle adjustment of the fixing frame in the left and right direction. It should be noted that after adjusting the three-way joint 500 between the column body 310 and the crossbeam 100, in order to prevent interference between the column body 310 and the diagonal bracing beam 400 and interference between the diagonal bracing beam 400 and the crossbeam 100, and to ensure the normal assembly of the photovoltaic bracket 1000, it is also necessary to adjust the three-way joint 500 between the column body 310 and the diagonal bracing beam 400, as well as the three-way joint 500 between the diagonal bracing beam 400 and the crossbeam 100.

[0072] It can be understood that the specific structure of the three-way joint 500 between the column body 310 and the diagonal bracing beam 400 and the specific structure of the three-way joint 500 between the diagonal bracing beam 400 and the cross beam 100 are the same as the specific structure of the three-way joint 500 between the column body 310 and the cross beam 100. In order to ensure the simplicity of the text, they will not be repeated here.

[0073] In order to further reduce the overall weight of the photovoltaic support 1000, in this embodiment, the cross beam 100, the longitudinal beam 200, the column body 310 and the diagonal bracing beam 400 are all made of basalt fiber material, and the cross beam 100, the longitudinal beam 200, the column body 310 and the diagonal bracing beam 400 are all square tube structures, so as to effectively reduce the overall weight of the photovoltaic support 1000 and ensure the structural strength of the cross beam 100, the longitudinal beam 200, the column body 310 and the diagonal bracing beam 400. In addition, due to the low density and high strength of the basalt fiber material, the cost of the basalt fiber material required in the production process is lower than the conventional steel cost, saving production costs. In addition, for the photovoltaic support made of steel in the prior art, since the photovoltaic support is used in an open-air environment, it is also necessary to regularly perform anti-rust treatment on the photovoltaic support made of steel, and the maintenance cost is high. The photovoltaic support made of basalt fiber material can utilize the high corrosion resistance of the basalt fiber material itself, without the need for subsequent anti-rust treatment, reducing the subsequent maintenance cost.

[0074] As an optional solution, the inner cavity wall of the free end of the first branch joint 510 is sleeved and fixed with the outer peripheral wall of the column body 310, the diagonal bracing beam 400 or the cross beam 100, and the free end of the first branch joint 510 is the end of the first branch joint 510 away from the second branch joint 520 and the third branch joint 530. By sleeved and fixedly fixing the inner cavity wall of the free end of the first branch joint 510 away from the second branch joint 520 and the third branch joint 530 with the outer peripheral wall of the column body 310, the diagonal bracing beam 400 or the cross beam 100, the first branch joint 510 can be firmly connected with the column body 310, the diagonal bracing beam 400 or the cross beam 100 of the column body 310, thereby improving the structural strength.

[0075] like Figure 5 As shown, the first fixing member 511 includes a fixing bolt 5111 and a fixing nut 5112. The fixing bolt 5111 penetrates and extends out of the first branch joint 510 and the column body 310, the diagonal bracing beam 400 or the cross beam 100, and the fixing nut 5112 is threadedly fixed to the protruding end of the fixing bolt 5111. By using the fixing bolt 5111 to penetrate and extend out of the first branch joint 510 and the column body 310, the diagonal bracing beam 400 or the cross beam 100, and using the fixing nut 5112 to threadably fix to the protruding end of the fixing bolt 5111, the first branch joint 510 and the column body 310, the diagonal bracing beam 400 or the cross beam 100 can be detachably fixed, which is convenient for the subsequent inspection and maintenance of the column body 310, the diagonal bracing beam 400 and the cross beam 100.

[0076] It should be noted that, in this embodiment, the specific structure between the second fixing member 521 in the second branch joint 520 and the column body 310, and the specific structure between the third fixing member 531 in the third branch joint 530 and the beam 100 are the same as the specific structure between the first fixing member 511 in the first branch joint 510 and the beam 100. To ensure the conciseness of the text, they will not be repeated here.

[0077] Combination Figure 6 The specific structure between the cross beam 100 and the longitudinal beam 200 is described. Figure 6 As shown, the photovoltaic support 1000 also includes a first fixing structure 600, wherein the first fixing structure 600 includes an L-shaped connector 610 and a first locking member 620, the cross beam 100 and the longitudinal beam 200 overlap each other, the two straight portions 611 of the L-shaped connector 610 abut against the cross beam 100 and the longitudinal beam 200 respectively, and the first locking member 620 is configured to lock and fix the two straight portions 611 of the L-shaped connector 610 with the cross beam 100 and the longitudinal beam 200. By providing the L-shaped connector 610, the two straight portions 611 of the L-shaped connector 610 abut against the overlapped cross beam 100 and the longitudinal beam 200 respectively, and the first locking member 620 is used to lock and fix the cross beam 100 and the straight portion 611 and the longitudinal beam 200 and the straight portion 611 respectively, the structure is simple, the design is ingenious, and the fixing effect is good.

[0078] In order to further improve the fixing effect of the cross beam 100 and the longitudinal beam 200 , first fixing structures 600 are provided on both sides of the overlapped cross beam 100 and the longitudinal beam 200 , and the two first fixing structures 600 simultaneously connect and fix the cross beam 100 and the longitudinal beam 200 .

[0079] It should be noted that the specific structure of the first locking member 620 is the same as the specific structure of the first fixing member 511 , and will not be described in detail here to ensure brevity.

By arranging the protruding end of the fixing bolt 5111 and the fixing nut 5112 in the inner cavity of the first branch joint 510 and the column body 310, the diagonal bracing beam 400 or the cross beam 100, the overall aesthetics of the photovoltaic bracket 1000 can be further improved.

Compared with the first fixing structure 600 in the first embodiment, the second fixing structure 700 does not need to provide two L-shaped connectors 610, reduces the number of parts for fixing the cross beam 100 and the longitudinal beam 200, and improves the fixing efficiency.

[0086] It should be noted that, in this embodiment, the longitudinal beam 200 is overlapped on the top of the cross beam 100, and the longitudinal beam 200 is accommodated in the receiving groove 7111 of the bent portion 711, and the straight portion 712 is in contact with the cross beam 100, so that the second locking member 720 can lock and fix the bent portion 711 with the longitudinal beam 200, and the straight portion 712 with the cross beam 100. In other embodiments, the cross beam 100 can also be overlapped on the top of the longitudinal beam 200, and the cross beam 100 is accommodated in the receiving groove 7111 of the bent portion 711, and the straight portion 712 is in contact with the longitudinal beam 200, so that the second locking member 720 can lock and fix the bent portion 711 with the cross beam 100, and the straight portion 712 with the longitudinal beam 200, which is not specifically limited in this embodiment.

[0087] In addition, the specific structure of the second locking member 720 is the same as the specific structure of the first fixing member 511 in the first embodiment, and will not be described again for simplicity.

[0088] As an alternative, Fig. 9 As shown, the photovoltaic support 1000 further includes a support sleeve 800, which is fixedly disposed on the bending portion 711 and the longitudinal beam 200 in the receiving groove 7111, and the second locking member 720 is fixedly disposed in the inner cavity of the support sleeve 800. By disposing the support sleeve 800 through the bending portion 711 and the longitudinal beam 200 received in the receiving groove 7111, and by disposing the second locking member 720 in the inner cavity of the support sleeve 800, the locking force of the second locking member 720 can be absorbed by the support sleeve 800, thereby preventing the locking force of the second locking member 720 from crushing the longitudinal beam 200.

[0089] It can be understood that the support sleeve 800 can also be applied to the assembly structure of the first fixing member 511 and the column body 310, the diagonal bracing beam 400 or the cross beam 100 in Example 1, the assembly structure of the second fixing member 521 and the column body 310, the diagonal bracing beam 400 or the cross beam 100, and the assembly structure of the third fixing member 531 and the column body 310, the diagonal bracing beam 400 or the cross beam 100, and this embodiment does not make specific limitations.
