[0065] Since one of the first connecting member 4 and the second connecting member 5 is provided with an arc-shaped through hole 6 used to connect the other, when the first connecting member 4 and the second connecting member 5 are coaxially arranged and connected through the fixing member, the relative rotation between the two can be allowed to adjust the relative angular position relationship therebetween; when the relative angular position relationship between the first connecting member 4 and the second connecting member 5 is adjusted, the azimuth of the photovoltaic module arranged on the support 2 is synchronously changed, so that the azimuth adjustment process of the photovoltaic module is realized, which not only ensures the safety of the photovoltaic device, but also reduces the workload and saves the installation or maintenance cost.

[0066] It should be noted that in the embodiment, the protruding part 41 and the insertion part 51 are used to define the axis of the relative rotation between the first connecting member 4 and the second connecting member 5, so that the relative rotation between the first connecting member 4 and the second connecting member 5 is allowed; under the premise of meeting the action of the protruding part 41 and the insertion part 51, the cross section of one of the protruding part 41 and the insertion part 51 can be circular, and the other can be a regular polygon matched therewith, or as shown in Figure 7 , Figures 2 to 5 , the cross sections of the protruding part 41 and the insertion part 51 can both be circular; by increasing the friction between the first connecting member 4 and the second connecting member 5, the stability of the connection between the first connecting member 4 and the second connecting member 5 is improved, and the axial deviation of the first connecting member 4 relative to the second connecting member 5 is avoided.

[0067] Further, in the embodiment, when the cross section of the protruding part 41 is circular, as shown in Figure 7As shown, the protrusion 41 can be frustum-shaped, frustum-shaped, hemispherical, or any other shape that satisfies the function of the protrusion 41; and the insertion part 51 matches the shape of the protrusion 41.

[0068] Furthermore, in this embodiment, when the protrusion 41 is in the shape of a frustum or a hemisphere, and one of the first connector 4 and the second connector 5 is connected to the bottom end of the column 1 while the other is connected to the installation position, the installation state between the first connector 4 and the second connector 5 can be adjusted according to the horizontal state of the installation position, thereby adjusting the verticality of the column 1 and increasing the safety and stability of the support structure.

[0069] Furthermore, in this embodiment, to increase the friction between the first connector 4 and the second connector 5, a first anti-slip portion 411 can be provided on the outer surface of the protrusion 41, and / or a second anti-slip portion 511 can be provided on the inner surface of the insertion portion 51. The anti-slip portion can be an anti-slip pad, an anti-slip coating, or an anti-slip protrusion. The anti-slip protrusion can also be, for example, Figures 2 to 7 The convex edge shown.

[0070] Furthermore, in this embodiment, the insertion part 51 may be as follows: Figure 7 and Figure 3 The recess of the corresponding shape on the second connector 5 shown; or it can be as follows Figure 4 The corresponding shape of the through hole is shown.

[0071] like Figure 7 As shown, it should be noted that in this embodiment, to increase the strength and reliability of the connection between the first connector 4 and / or the second connector 5 and the column 1, based on the different positions of the first connector 4 and the second connector 5, it can be achieved in the following ways:

[0072] The first implementation method, such as Figures 1 to 7 As shown, when the first connecting member 4 and the second connecting member 5 are disposed between the column 1 and the support member 2, the support structure proposed in this embodiment also includes a clamping member.

The clamping member can also extend from the edge of the first connecting member 4 towards the bottom end of the column 1, and / or extend from the edge of the second connecting member 5 towards the bottom end of the column 1. The clamping member assists the first connecting member 4 and the second connecting member 5 in connecting the support member 2 to the column 1. When the clamping member is an independent component, based on satisfying the function of the clamping member, the clamping member can be a claw-type clamp, which clamps the column 1. Figures 1 to 5 As shown, the clamping member can also be a sleeve 31, which is sleeved on the column 1.

[0073] Further, in the present embodiment, when the clamping member adopts the sleeve 31, in order to improve the clamping force of the clamping member on the stand 1, at least one u-shaped notch 311 can be arranged on the sleeve wall of the sleeve 31, at this time, the support structure proposed in the present embodiment further comprises a hoop 32 arranged at the axial position of the sleeve 31 provided with the notch 311, for abutting the sleeve wall of the sleeve 31 against the outer circumferential surface of the stand 1, thereby increasing the stability of the sleeve 31 connected to the stand 1, and preventing the support member 2 from being circumferentially deviated relative to the stand 1.

[0074] It should be noted that, in order to increase the stability of the sleeve 31 connected to the stand 1, and prevent the azimuth angle of the photovoltaic module from being undesirably changed due to external force acting on the photovoltaic module, a third anti-skid part can be arranged on the sleeve wall of the sleeve 31, thereby increasing the friction between the clamping member and the stand 1, and further increasing the stability of the support member 2 connected to the stand 1, and preventing the support member 2 from being circumferentially deviated relative to the stand 1. Similarly, the third anti-skid part can be an anti-skid pad, an anti-skid coating or an anti-skid protrusion.

[0075] The second implementation mode is shown in Figures 1 to 5 and Figure 6 When the first connecting member 4 and the second connecting member 5 are arranged between the stand 1 and the mounting position, at this time, the support structure proposed in the present embodiment further comprises a plurality of reinforcing ribs 8, the plurality of reinforcing ribs 8 are arranged in a ring array along the stand 1, one end of each of the reinforcing ribs 8 is connected to the stand 1, and the other end of each of the reinforcing ribs 8 is connected to the first connecting member 4 or the second connecting member 5 connected to the bottom end of the stand 1. As shown in Figure 7 and Figure 6 Figure 7 The reinforcing rib 8 is a triangular metal block.

[0076] It should be noted that, in the present embodiment, the fixing member cooperates with the connecting part 7 on the first connecting member 4 to connect the second connecting member 5 to the first connecting member 4 from the arc-shaped through hole 6, and the implementation mode of the connecting part 7 includes but is not limited to the following modes:

[0077] The first mode is that the connecting part 7 is a screw rod on the first connecting member 4 or the second connecting member 5, and the fixing member is a nut matched with the screw rod.

[0078] The second mode is that the connecting part 7 can be a connecting hole penetrating through the first connecting member 4 or the second connecting member 5, at this time, the fixing member is a combination of a bolt and a nut; or the connecting part 7 can be a threaded hole, at this time, the fixing member is a bolt matched with the threaded hole, and the bolt passes through the arc-shaped through hole 6 and is connected to the threaded hole.

[0081] First, the support structure of the present application uses the first connecting member 4 and the second connecting member 5 to fix one of them at the mounting position or the support member 2, and the other one at the bottom end or the top end of the stand column 1, and the relative rotation of the two can adjust the azimuth angle of the photovoltaic module. The fixing member cooperates with the connecting part 7 to connect the first connecting member 4 to the second connecting member 5 at the arc-shaped through hole 6. Since the arc-shaped through hole 6 is provided, the fixing member only needs to be loosened to accurately adjust the azimuth angle of the photovoltaic module. After the adjustment is completed, the fixing member is tightened to fix the first connecting member 4 and the second connecting member 5. The adjustment process ensures the safety of the photovoltaic device, reduces the workload, and saves the installation or maintenance cost.

[0083] Especially when the outer surface of the protruding part 41 is provided with the first anti-skid part 411, and / or the inner surface of the insertion part 51 is provided with the second anti-skid part 511, the stability of the connection between the first connecting member 4 and the second connecting member 5 is further increased.

[0084] When the protruding part 41 is in the shape of a spherical platform or a hemisphere, and one of the first connecting member 4 and the second connecting member 5 is connected to the bottom end of the stand column 1, and the other one is connected to the mounting position, the mounting state between the first connecting member 4 and the second connecting member 5 is adjusted according to the horizontal state of the mounting position, so as to adjust the verticality of the stand column 1.

[0085] Third, when one of the first connecting member 4 and the second connecting member 5 is connected to the support member 2, the sleeve 31 is used to assist the connection of the support member 2 to the stand column 1, so as to increase the stability of the connection of the support member 2 to the stand column 1. In use, the hoop 32 is clamped at the notch 311 of the sleeve 31, so that the cylinder wall of the sleeve 31 is pressed against the stand column 1, thereby increasing the friction between the sleeve 31 and the stand column 1, and increasing the stability of the connection of the support member 2 to the stand column 1.

[0086] Fourth, when one of the first connecting member 4 and the second connecting member 5 is connected to the installation position, by setting a plurality of reinforcing ribs 8, one end of the reinforcing rib 8 is connected to the stand column 1, and the other end is connected to the first connecting member 4 or the second connecting member 5 connected to the bottom end of the stand column 1, by setting the reinforcing rib 8 on the outer circumferential surface of the stand column 1, the reinforcing rib 8 is connected to the first connecting member 4 or the second connecting member 5 connected to the installation position, and the stability of the stand column 1 is increased under the action of the reinforcing rib 8.
