Figure 4 A schematic diagram of the three-dimensional structure of a limiting ring piece used in a photovoltaic support foundation provided in one embodiment of the present application.

[0031] The embodiment of the present application provides a photovoltaic support foundation, such as Figure 1 As shown, it includes a basic body 100, a connecting rod 200 and a bolt 400, wherein the basic body 100 is a structure for installing and supporting other components, the connecting rod 200 is a structure connected to the photovoltaic bracket, and the bolt 400 is used for fastening.

[0032] like Figure 2 As shown, two mounting plates 110 are provided at the top of the basic body 100, and the two mounting plates 110 are respectively located at the two ends of the top of the basic body 100. A mounting shaft 120 is provided between the two mounting plates 110, and the mounting shaft 120 can be detachably connected to facilitate the installation of other components.

[0033] like Figure 2 As shown, an arc-shaped long hole 130 is provided on the mounting plate 110 , and the center of the arc-shaped long hole 130 is on the axis of the mounting shaft 120 , that is, the arc-shaped long hole 130 is coaxially arranged with the mounting shaft 120 .

[0034] like Figure 3 As shown, a mounting hole 210 is provided at the lower end of the connecting rod 200 , and the connecting rod 200 is rotatably connected to the mounting shaft 120 through the mounting hole 210 , thereby realizing the rotatable connection between the connecting rod 200 and the mounting shaft 120 .

[0035] like Figure 3 As shown, a through hole 220 is provided above the mounting hole 210, and the distance between the center of the through hole 220 and the center of the mounting hole 210 is equal to the radius of the arc-shaped long hole 130, that is, when the connecting rod 200 rotates, the through hole 220 can always be opposite to the arc-shaped long hole 130.

[0036] like Figure 1As shown, a connecting plate 300 is provided at the upper end of the connecting rod 200, and the connecting plate 300 can be connected to the photovoltaic support.

[0037] like Figure 1 As shown, the bolt 400 passes through the arc-shaped long hole 130 and the through hole 220 on the two mounting plates 110 and is fastened by a nut. The end of the bolt 400 abuts against one mounting plate 110 and the nut abuts against the other mounting plate 110, thereby fixing the position of the connecting rod 200.

[0038] It should be noted that the arc-shaped long hole 130 can realize continuous adjustment of the position of the connecting rod 200 within a certain range, and the position of the connecting rod 200 can be fixed by the tightening force of the bolt 400 and the nut. In specific implementation, the arc-shaped long hole 130 can also be set as a plurality of fixing holes, and these plurality of fixing holes are spaced apart along the circumferential direction of the arc-shaped long hole 130 to realize the interval adjustment of the position of the connecting rod 200. At the same time, the mutual cooperation between the fixing hole and the through hole 220 can also improve the reliability of the position of the connecting rod 200.

[0039] When in use, at least two photovoltaic bracket foundations are generally used together to support different positions of the photovoltaic bracket. During installation, the connecting rod 200 can be rotated around the installation axis 120 to change the position and angle of the connecting rod 200. The connecting plate 300 on the connecting rod 200 can be connected to various types of photovoltaic brackets. After the connecting rod 200 is adjusted into place, the bolt 400 can be passed through the arc-shaped long hole 130 and the through hole 220, and tightened with a nut, thereby keeping the position of the connecting rod 200 fixed and ensuring the reliability of the connection.

[0040] Compared with the prior art, the connecting rod 200 of the photovoltaic bracket base can be rotated to achieve position and angle adjustment, so that different types of photovoltaic brackets and complex on-site installation environments can be connected, thereby reducing installation difficulty and expanding the scope of application.

[0041] In some embodiments, Figure 1 and Figure 4As shown, the photovoltaic support foundation also includes a limiting ring piece 500, and a limiting shaft 510 is provided on the edge of the limiting ring piece 500, and the limiting shaft 510 extends along the axial direction of the limiting ring piece 500. A plurality of limiting holes 140 are provided on the outer side of the arc-shaped long hole 130, and the outer side here refers to the side away from the center of the arc-shaped long hole 130. The plurality of limiting holes 140 are arranged at intervals along the circumferential direction of the arc-shaped long hole 130. The limiting ring piece 500 is arranged on the bolt 400, and the two sides of the limiting ring piece 500 are respectively abutted against the mounting plate 110 and the bolt 400, and the limiting shaft 510 is plugged into a limiting hole 140. When the connecting rod 200 is adjusted into position, the limiting ring piece 500 can be plugged into a limiting hole 140 through the limiting shaft 510, so as to fix the position of the limiting ring piece 500, that is, to keep the position of the bolt 400 fixed, and keep the position of the connecting rod 200 fixed, thereby preventing the connecting rod 200 from tilting.

[0042] In some embodiments, Figure 4 As shown, a guiding slope is provided at the end of the limiting shaft 510 to facilitate the limiting shaft 510 to be inserted into the limiting hole 140 for easy operation.

[0043] In some embodiments, the thickness of the limiting ring piece 500 is at least 2 mm, so that the limiting ring piece 500 has sufficient structural strength to withstand the extrusion of the bolt 400 and ensure the connection strength of the bolt 400.

[0044] In some embodiments, the mounting plate 110 is provided with a scale, and the scale can show the angle between the connecting rod 200 and the horizontal plane. When the connecting rod 200 rotates to a certain position, the angle of the connecting rod 200 can be observed through the scale, which is convenient to use.

[0045] In some embodiments, Figure 1 As shown, the photovoltaic support foundation also includes a spacer 600, which is sleeved on the mounting shaft 120, and the two sides of the spacer 600 are respectively in contact with the mounting plate 110 and the connecting rod 200. There are two spacers 600, which are respectively located on both sides of the connecting rod 200. The spacer 600 separates the connecting rod 200 from the mounting plate 110, and can keep the axial position of the connecting rod 200 fixed along the mounting shaft 120. At the same time, the connecting rod 200 and the mounting plate 110 are not in contact, which facilitates the rotation of the connecting rod 200.

[0046] In some embodiments, Figure 1 As shown, the connecting plate 300 is rotatably connected to the top end of the connecting rod 200, so that the connecting plate 300 can be adjusted in angle and can be connected to different types of photovoltaic brackets, thereby reducing the difficulty of installation and increasing the scope of application.

[0047] In some embodiments, Figure 1As shown, a plurality of connection holes 310 are provided on the connection plate 300, and the connection holes 310 cooperate with the holes on the photovoltaic bracket to achieve connection by sampling bolt connection.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
