[0044] As a first aspect of this embodiment, Figures 1 to 4 As shown, as a first aspect of the utility model, a support structure 1 is used to support a dual-axis tracking photovoltaic device, comprising:

[0045] The first support member 11 and the second support member 12 are symmetrical.

[0046] The first support member 11 is in an isosceles trapezoidal shape, and its upper surface is a mounting surface 111. The shorter side of the two parallel sides of the trapezoidal first support member 11 is a first mounting portion 112, and the other side is a second mounting portion 113. The two oblique sides extend toward the outside of the first mounting portion 112 to form a first extension section 114. The extension end of the first extension section 114 is used to connect with the second support member 12.

[0047] It also includes at least four support rods 13, wherein at least two of the support rods 13 are used to support the first support member 11 and one end of the support rods 13 is connected to the first support member 11, and at least two of the support rods 13 are used to support the second support member 12 and one end of the support rods 13 is connected to the second support member 12.

[0048] One of the support rods 13 is supported at the bottom of one end of the second mounting portion 113, and another of the support rods 13 is supported at the bottom of the other end of the second mounting portion 113.

[0049] The other ends of the plurality of support rods 13 are connected.

[0050] It should be noted that the symmetry of the first support member 11 and the second support member 12 means that when in use, when the first support member 11 and the second support member 12 are matched and clamped on the vertical pole 5, the first support member 11 and the second support member 12 are symmetrical with the axis of the vertical pole 5 as the axis of symmetry, that is, the first support member 11 and the second support member 12 have the same structure. For the convenience of expression, only the first support member 11 is described in this embodiment.

[0051] It should be noted that in order to facilitate the connection of the support structure 1 of this embodiment to the vertical pole 5 and to make the hoop more stable, the following is specifically described: the opposite surfaces between the two first extension sections 114 of the first support member 11 and the outer side surface 112 of the first mounting portion form an arc shape. At this time, the first support member 11 forms a circle that matches the main body through the first extension section 114 and the second support member 12, so that the first support member 11 and the second support member 12 are matched to be hooped on the vertical pole 5, thereby improving the convenience of use and installation.

[0052] By using multiple support rods 13, one end of the multiple support rods 13 is respectively connected to the first support member 11 and the second support member 12, and the other end is connected and supported on the vertical pole 5, thereby improving the overall stability of the support structure 1 proposed in this embodiment. Furthermore, one end of the support rod 13 connected to the first support member 11 and the second support member 12 is respectively connected to the two ends of the second mounting portion 113, thereby improving the load capacity of the second mounting portion 113. When the dual-axis tracking photovoltaic device is set on the second mounting portion 113 through the powertrain 2, the support structure 1 proposed in this embodiment can support the photovoltaic device more stably.

[0053] It should be noted that, in this embodiment, in order to improve the overall strength of the first support member 11 and enhance its bending resistance, Figure 1 As shown, when the first support member 11 is placed horizontally and the mounting surface 111 faces upward, the edge of the first support member 11 extends downward, wherein the edge of the first support member 11 may be the entire edge or a portion thereof.

[0054] Extending the edge of the first support member 11 downward not only avoids the first support member 11 from bending under force, increases its overall strength and bending resistance, but also increases the connection area between the first extension section 114 and the vertical pole 5, as well as the connection area between the first support member 11 and the second support member 12, thereby improving the stability of the connection between the first support member 11 and the second support member 12, the first support member 11 and the vertical pole 5, and the second support member 12 and the vertical pole 5.

[0055] Furthermore, in this embodiment, the first support member 11 further includes a reinforcing portion 115, such as Figure 1 and Figure 2 As shown, the reinforcing portion 115 is a depression and / or protrusion arranged on the mounting surface 111, and the above-mentioned depression and / or protrusion can be regular shapes such as long strips, squares, diamonds, etc., or can be irregular shapes such as circles and arcs; the reinforcing portion 115 further enhances the overall strength of the first support member 11 and improves its bending resistance, especially enhances the strength of the mounting surface 111 and improves its bending resistance.

[0056] It should be noted that when using the support structure 1 proposed in this embodiment, the extension end 114 of the first extension section 114 can be directly fixedly connected to the vertical pole 5 by welding or the like, or can be connected to the vertical pole 5 by connecting parts such as bolts, screws or rivets.

[0057] Furthermore, in order to facilitate the connection of the first support member 11, the second support member 12 and the vertical pole 5 in the support structure 1 proposed in this embodiment, as shown in FIG. Figure 1 , Figure 3 and Figure 4 As shown, the support structure 1 also includes two groups of first connecting members 14, and the first supporting member 11 and the second supporting member 12 are both connected to the first connecting member 14. Similarly, the first connecting member 14 can be fixedly connected to the vertical pole 5, for example, directly welded to the vertical pole 5; or the first connecting member 14 can be detachably connected to the vertical pole 5 by bolts, screws or rivets.

[0058] It should be noted that, in the present embodiment, the other end of the support rod 13 may be directly connected to the upright pole 5 by welding or the like, or may be connected to the upright pole 5 by a connecting member such as a bolt, a screw or a rivet.

[0059] Furthermore, in order to facilitate the connection of the plurality of support rods 13 in the support structure 1 proposed in this embodiment with the vertical rods 5, as shown in FIG. Figure 1 , Figure 3 and Figure 4 As shown, the support structure 1 also includes a second connecting member 15, and the other ends of the plurality of support rods 13 are connected to the second connecting member 15; the second connecting member 15 can be fixedly connected to the vertical pole 5, for example, directly welded to the vertical pole 5, or the second connecting member 15 can be detachably connected to the vertical pole 5 by bolts, screws or rivets.

[0060] It should be noted that, in the present embodiment, the first support member 11 and the second support member 12 are sheet metal members, that is, the first support member 11 and the second support member 12 are both made by sheet metal processing. Compared with ordinary plate connection or combination, the first support member 11 and the second support member 12 made by sheet metal processing are higher in strength and easier to process in batches because they are integrally formed. At the same time, they are lighter in weight because less material is used.

[0061] As a second aspect of this embodiment, Figures 3 to 5As shown, a photovoltaic tracking system includes a photovoltaic device, which includes a photovoltaic panel 4, a powertrain 2 for driving the photovoltaic panel 4 to rotate, a booster 3 for assisting the powertrain 2, and a vertical pole 5; it also includes the support structure 1 as described above, the support structure 1 is connected to the second support member 12 through the extended end of the first extension section in the first support member 11 and then is hooped on the vertical pole 5; four groups of first fixing members 16 are respectively arranged on the first support member 11 and the second support member 12, and are arranged on the mounting surface 111, located at both ends of the first mounting portion 112, and are used to connect the booster 3; four groups of second fixing members 17 are respectively arranged on the first support member 11 and the second support member 12, and are arranged on the mounting surface 111, located at both ends of the second mounting portion 113, and are used to connect the powertrain 2.

[0062] Among them, the four sets of second fixing members 17 respectively arranged on the first support member 11 and the second support member 12 can connect two sets of power assemblies 2. The second fixing members 17 can be connected to the power assembly 2 by using two sets of second fixing members 17 simultaneously arranged on the first support member 11 to connect one set of power assembly 2, or as Figure 5 As shown, one end of a power assembly 2 is connected to a second fixing member 17 on the first support member 11 , and the other end is connected to a second fixing member 17 disposed on the second support member 12 .

[0063] It should be noted that the booster 3 used to assist the power assembly 2 means that when the photovoltaic tracking system proposed in this embodiment is performing dual-axis tracking, the booster 3 can provide auxiliary force for the power assembly 2 to drive the photovoltaic panel 4 to move. The detailed function and structure of the booster 3 have been described in detail in the Chinese patents previously submitted by the applicant (such as application numbers: CN202420340371.3; CN202410203081.9), which will not be repeated here.

[0064] When the booster 3 assists the power assembly 2, there will be a certain force between the two, so that the booster 3 will be offset to a certain extent in the direction away from the power assembly 2, thereby affecting the working efficiency and stability of the booster 3. To solve this problem, the two groups of the first fixing members 16 are connected. The implementation method of the connection of the first fixing members 16 is as follows:

[0065] In the first embodiment, the two groups of first fixing members 16 are fixedly connected, for example, by welding; or the two groups of first fixing members 16 are integrated into one body, that is, the two groups of first fixing members 16 are formed into one body at one time.

[0066] In the second embodiment, the two groups of first fixing members 16 are detachably connected. For example, the two groups of first fixing members 16 are connected via a connecting block 161. In order to enable the connecting block 161 to be connected to the first fixing member 16 more quickly and conveniently, plug-in parts can be provided on both sides of the connecting block 161, and plug-in grooves matching the plug-in parts can be provided on the first fixing member 16. The connecting block 161 is respectively connected to the first fixing members 16 on both sides via the plug-in parts.

[0067] Furthermore, in this embodiment, since the axial length of the booster 3 is relatively long, in order to further ensure that the relative position between the booster 3 and the power assembly 2 does not change, a limit member 18 is also provided on the second mounting portion 113. The limit member 18 is used to limit the booster 3 extending to the second mounting portion 113, thereby further improving the working efficiency and stability of the booster 3.

[0068] It should be noted that, in this embodiment, the connection methods between the first fixing member 16 and the second fixing member 17 and the mounting surface 111 include but are not limited to:

[0069] First, the first fixing member 16 and the second fixing member 17 are fixedly connected to the mounting surface 111 , for example, by welding.

[0070] Second, the first fixing member 16 and the second fixing member 17 are movably connected to the mounting surface 111 , for example, by bolts, screws or rivets.

[0071] When the first fixing member 16 and the second fixing member 17 are movably connected to the mounting surface 111, in order to facilitate and quickly position and connect the first fixing member 16 and the second fixing member 17, as shown in FIG. Figure 3 and Figure 4 As shown, the first mounting portion 112 is further provided with a first positioning portion for positioning the first fixing member 16 , and / or the second mounting portion 113 is further provided with a second positioning portion for positioning the second fixing member 17 .
