[0029] As Figures 1 to 11As shown, it shows the adjustable photovoltaic support in an embodiment of the present application, including the base 1, a plurality of base 1 is equidistantly provided, the upper part of a plurality of base 1 is provided with support frame 2, further comprising support assembly, photovoltaic panel 3, angle adjusting assembly, locking assembly, support sleeve 4, sliding sleeve 5 and height adjusting assembly, the top of each support frame 2 is installed with support assembly, the upper part of each support assembly is fixedly installed with a plurality of photovoltaic panels 3, the support assembly comprises support beam 6, cross beam 7, connecting beam 8 and butt joint part, the top of each support frame 2 is provided with a group of support beams 6, each group of support beams 6 is symmetrically provided with two, the two symmetrically arranged support beams 6 are arranged in parallel, wherein a plurality of photovoltaic panels 3 are fixedly installed on each group of support beams 6, the two support beams 6 between the top of each support frame 2 are fixedly installed with cross beam 7, the two sides of each cross beam 7 are provided with connecting beam 8, the two ends of connecting beam 8 are respectively fixedly connected with the corresponding position of support beam 6, wherein the cross beam 7 is rotatably connected with the top of support frame 2, the butt joint part is installed between every two groups of support assemblies, for connecting the support beams 6 in each support assembly.

[0030] Specifically, when installing the photovoltaic support, first, the size, slope and orientation of the site are measured, then the positions between a plurality of bases 1 are designed, after the support sleeve 4 and the sliding sleeve 5 are installed, the photovoltaic support can be installed, at this time, the support frames 2 are installed on the top of a plurality of sliding sleeves 5 (which can be connected by bolts or welded), in order to adapt to the installation requirements of different sites, when the height of the photovoltaic support needs to be adjusted, the height of the support frame 2 can be adjusted through the setting of the height adjusting assembly, so as to adjust the height of the photovoltaic panel 3, then the support beams 6, cross beams 7 and connecting beams 8 in the support assembly are assembled (which can be assembled together by screw connection or welding), then the assembled support assembly is installed on the top of the corresponding support frame 2, that is, the cross beam 7 of the support assembly is rotatably connected with the top of the support frame 2 through the hinge, after the corresponding support assembly is installed on the top of a plurality of support frames 2, the plurality of support assemblies are connected together, then the angle adjusting assembly and the locking assembly are installed, and the photovoltaic panels 3 are installed on the plurality of support assemblies in a certain order.

[0031] When the included angle between the support assembly and the ground needs to be adjusted, the angle position of the support assembly can be adjusted by driving the angle adjusting assembly, through the setting of the locking assembly, after the angle of the support assembly is adjusted, the relative position of the support assembly and the support frame 2 can be further fixed, so as to further improve the stability of the whole photovoltaic support.

[0032] In some examples, as Figure 3 , Figure 4As shown, the abutting portion comprises a connecting frame 9 and connecting bolts 10, each set of support beams 6 is provided with two, the end of the support beams 6 of each adjacent two sets of components is arranged in abutment, the connecting frame 9 is arranged between each two abutting support beams 6, and two sets of connecting bolts 10 are fixedly installed on each connecting frame 9, and each set of connecting bolts 10 is fixedly connected with two support beams 6 respectively.

[0033] Specifically, after the corresponding support assembly is installed on the top of each support frame 2, at this time, the two support beams 6 in each support assembly correspond to and abut against the two support beams 6 in an adjacent support assembly, as shown in Figure 3 As shown, the two ends of each support beam 6 are provided with through holes to facilitate the installation of the connecting bolts 10, when the two end-abutted support beams 6 need to be connected together, the connecting frame 9 is placed at the abutting position of the two support beams 6, the through holes on the connecting frame 9 are overlapped with the through holes at the ends of the support beams 6, and then the two end-abutted support beams 6 are fixed by the connecting bolts 10.

[0034] In some examples, as shown in Figures 5 to 8 Each support frame 2 is provided with an angle adjusting assembly for adjusting the angle between the support assembly and the photovoltaic panel 3, the angle adjusting assembly comprises a screw jack 11 and a connecting portion, the screw jack 11 is rotatably installed on each support frame 2, the output end of each screw jack 11 is rotatably connected with the bottom of the corresponding cross beam 7, wherein the bottom of each screw jack 11 is provided with a driving structure, and the driving structures of every two screw jacks 11 are provided with a connecting portion, which is used to synchronously drive other screw jacks 11 when the outermost screw jack 11 is driven.

[0035] Specifically, when the screw jack 11 is installed, the base 1 of the screw jack 11 is rotatably installed on the corresponding support frame 2 by hinging, and the height of each screw jack 11 is kept consistent, then the output end of the screw jack 11 is rotatably connected with the corresponding cross beam 7 by hinging, and the installation of the screw jack 11 is completed, then the connecting portion is installed between the driving structures of every two adjacent screw jacks 11, as shown in Figure 5 and Figure 6 As shown, the output end of the driving structure of the outermost screw jack 11 is provided as a square column, when the screw jack 11 needs to be driven to stretch and contract to adjust the angle of the support assembly, the crank 25 as shown in Figure 6 is installed on the output end of the driving structure of the outermost screw jack 11, then the crank 25 is rotated to drive the output end of the screw jack 11 to rotate, and thus the screw jacks 11 are synchronously driven to stretch and contract through the connecting portion, so as to adjust the angle of the support assembly.

[0036] In some examples, as shown in Figure 5 The connecting part includes connecting shafts 12 and universal couplings 13. Each two driving structures of each two screw jacks 11 are provided with a set of connecting shafts 12. Each set of connecting shafts 12 is provided with two connecting shafts 12 arranged coaxially. The two connecting shafts 12 between each two screw jacks 11 are fixedly connected with the driving structures of the corresponding screw jacks 11 respectively. Inside each set of connecting shafts 12, i.e. between each two connecting shafts 12, a universal coupling 13 is coaxially fixedly installed.

[0037] Specifically, with the rotation of the handle 25, the multiple screw jacks 11 connected with the connecting shafts 12 and the universal couplings 13 can be driven to extend and retract through the arrangement of the connecting shafts 12 and the universal couplings 13. Even if the butt joint positions of the connecting shafts 12 have different angles, the torque can still be effectively transmitted through the arrangement of the universal couplings 13.

[0038] As shown in Figures 7 to 10 The locking assembly is installed between the support assembly and the support frame 2 and is used to lock the relative position between the support assembly and the support frame 2. The locking assembly includes arc-shaped positioning frames 14, arc-shaped sliding frames 15, and locking parts. Each support frame 2 is fixedly installed with an arc-shaped positioning frame 14 on the side away from the screw jack 11. Each arc-shaped positioning frame 14 is slidingly installed with an arc-shaped sliding frame 15 inside. The top end of each arc-shaped sliding frame 15 is fixedly connected with the corresponding cross beam 7. The sliding direction of the arc-shaped sliding frame 15 is a circular track with the rotation center of the cross beam 7 as the origin. The arc-shaped positioning frame 14 is installed with a locking part for fixing the relative position between the arc-shaped positioning frame 14 and the arc-shaped sliding frame 15.

[0039] Specifically, when the angle position of the support assembly is adjusted, the arc-shaped sliding frame 15 slides in the arc-shaped positioning frame 14 as the support assembly swings. Since the center positions of the arc-shaped positioning frame 14 and the arc-shaped sliding frame 15 coincide with the rotation center of the cross beam 7, the sliding of the arc-shaped sliding frame 15 is not affected. When the position of the support assembly is adjusted, the relative position between the arc-shaped positioning frame 14 and the arc-shaped sliding frame 15 can be fixed through the arrangement of the locking part.

[0040] In some examples, as shown in Figures 8 to 10 The locking part includes V-shaped sliding grooves 16, V-shaped positioning blocks 17, and position adjusting members. Each arc-shaped sliding frame 15 is provided with a V-shaped sliding groove 16 on the outer side. Each arc-shaped positioning frame 14 is slidingly installed with a V-shaped positioning block 17. The V-shaped positioning block 17 is adapted to the V-shaped sliding groove 16. Each arc-shaped positioning frame 14 is provided with a position adjusting member for adjusting the position of the V-shaped positioning block 17.

[0041] Specifically, when it is necessary to fix the relative position between the arc-shaped positioning frame 14 and the arc-shaped sliding frame 15, the V-shaped positioning block 17 is pushed into the V-shaped sliding groove 16 by setting the adjustment component. The part of the V-shaped positioning block 17 that contacts the V-shaped sliding groove 16 is made of a flexible material (such as rubber). When the V-shaped positioning block 17 abuts against the V-shaped sliding groove 16, the relative position between the arc-shaped positioning frame 14 and the arc-shaped sliding frame 15 can be fixed by setting the V-shaped sliding groove 16. When it is necessary to adjust the relative position between the arc-shaped positioning frame 14 and the arc-shaped sliding frame 15, the adjustment component can be released.

[0042] In some examples, such as Figure 9 As shown, the adjustment component includes adjustment screws 18 and adjustment nuts 19. Each arc-shaped positioning frame 14 is rotatably mounted with an adjustment screw 18, and each adjustment screw 18 is threaded with an adjustment nut 19. Several adjustment nuts 19 correspond one-to-one with several V-shaped positioning blocks 17 and are fixedly connected.

[0043] Specifically, when adjusting the position of the V-shaped positioning block 17, the adjusting screw 18 is turned to rotate, thereby pushing the V-shaped positioning block 17 to move through the setting of the adjusting nut 19. When the V-shaped positioning block 17 is pressed against the V-shaped slide groove 16, the relative position between the arc-shaped positioning frame 14 and the arc-shaped sliding frame 15 can be fixed. When the V-shaped positioning block 17 is not in contact with the V-shaped slide groove 16, the relative position between the arc-shaped positioning frame 14 and the arc-shaped sliding frame 15 will not be fixed.

[0044] like Figure 10 , Figure 11 As shown, a support sleeve 4 is fixedly installed on each base 1, and a sliding sleeve 5 is fixedly installed at the bottom of the support frame 2 set on the upper part of each base 1. Several sliding sleeves 5 correspond one-to-one with several support sleeves 4. Several sliding sleeves 5 are coaxially slidably installed inside the support sleeves 4. A height adjustment component is installed inside the support sleeves 4 to control the movement of the sliding sleeves 5. The height adjustment component includes an adjusting screw 20 and a drive unit. An adjusting screw 20 is rotatably installed inside each support sleeve 4. An adjusting nut 21 is threaded onto each adjusting screw 20. The adjusting nut 21 is fixedly connected to the sliding sleeve 5. A drive unit is installed inside each support sleeve 4 to drive the adjusting screw 20 to move.

[0045] Specifically, when adjusting the height of the support frame 2, the adjusting screw 20 is driven to rotate by the drive unit, thereby pushing the corresponding adjusting nut 21 to move. In turn, the adjusting nut 21 pushes the corresponding sliding sleeve 5 to move, thereby adjusting the height position of the support frame 2.

[0046] The above, such as Figure 11As shown, the drive unit includes a first helical gear 22, a second helical gear 23, and a connector 24. The first helical gear 22 is rotatably mounted on the inner bottom wall of each support sleeve 4. The first helical gear 22 is coaxially and fixedly connected to the adjusting screw 20. The second helical gear 23 is rotatably mounted on the side wall of each support sleeve 4. The second helical gear 23 meshes with the first helical gear 22. The connector 24 is rotatably mounted on each support sleeve 4. Several connectors 24 correspond one-to-one with several second helical gears 23 and are fixedly connected.

[0047] Specifically, when it is necessary to drive the adjusting screw 20 to rotate, first use a matching tool (such as a handle) to connect the connecting end of the handle to the connector 24, and then rotate the handle to drive the second helical gear 23 to rotate. Through the rotation of the second helical gear 23, the first helical gear 22 can be driven to rotate, thereby driving the adjusting screw 20 to rotate.

[0048] The working principle or usage process of this application is as follows: When installing photovoltaic (PV) brackets, the dimensions, slope, and orientation of the site must first be measured. Then, the positions of multiple bases 1 are designed. After the support sleeves 4 and sliding sleeves 5 are installed, the PV brackets can be installed. At this time, support frames 2 are installed on the top of multiple sliding sleeves 5 respectively. To adapt to the installation requirements of different sites, when the height of the PV bracket needs to be adjusted, the connecting end of the handle is connected to the connector 24, and then the handle is turned, which drives the second helical gear 23 to rotate. The rotation of the second helical gear 23 drives the first helical gear 22 to rotate, which drives the adjusting screw 20 to rotate, thereby pushing the corresponding adjusting nut 21 to move. By setting the adjusting nut 21, the corresponding sliding sleeve 5 is pushed to move, thereby adjusting the height position of the support frame 2, and thus adjusting the height of the PV panel 3.

[0049] Then, the support beams 6, crossbeams 7, and connecting beams 8 in the bracket assembly are assembled together (they can be assembled together by spiral connection or welding). The assembled bracket assembly is then installed on the top of the corresponding support frame 2, that is, the crossbeam 7 of the bracket assembly is rotatably connected to the top of the support frame 2 by hinges. After the corresponding bracket assemblies are installed on the tops of multiple support frames 2, the multiple bracket assemblies need to be connected together. At this time, the two support beams 6 in each group of bracket assemblies correspond one-to-one with the two support beams 6 in the adjacent group of bracket assemblies and abut against each other. Then, the connecting frame 9 is placed at the abutting position of the two support beams 6, so that the through hole on the connecting frame 9 coincides with the through hole at the end of the support beam 6. Then, by setting the connecting bolts 10, the two abutting support beams 6 at the ends can be fixed by the connecting frame 9.

[0050] Then install the screw jack 11, the arc-shaped positioning frame 14, and the arc-shaped sliding frame 15. Then install the connecting shaft 12 and the universal coupling 13 between every two adjacent screw jacks 11. The photovoltaic panels 3 can then be installed on multiple support components in a certain order. When it is necessary to adjust the angle between the support component and the ground, the V-shaped positioning block 17 does not contact the V-shaped sliding groove 16. Then, install the crank handle 25 at the output end of the drive structure of the outermost screw jack 11. Then turn the crank handle 25, thereby driving the output end of the screw jack 11 to rotate. As the crank handle 25 rotates, through the setting of the connecting shaft 12 and the universal coupling 13, multiple screw jacks 11 connected by the connecting shaft 12 and the universal coupling 13 can be driven to extend and retract, thereby synchronously driving all the screw jacks 11 to extend and retract, thereby adjusting the angle of the support component. As the support component swings, the arc-shaped sliding frame 15 slides within the arc-shaped positioning frame 14.

[0051] When it is necessary to fix the relative position between the arc-shaped positioning frame 14 and the arc-shaped sliding frame 15, the adjusting screw 18 is turned to rotate, thereby pushing the V-shaped positioning block 17 to move through the setting of the adjusting nut 19. When the V-shaped positioning block 17 abuts against the V-shaped sliding groove 16, the relative position between the arc-shaped positioning frame 14 and the arc-shaped sliding frame 15 can be fixed, thereby further improving the overall stability of the photovoltaic support.
