[0036] Embodiment 1

[0037] A fence type photovoltaic support, as shown in Figure 1 and Figure 2 , comprises a beam unit, the beam unit comprises a plurality of parallel arranged beams 1, two parallel arranged beams 1 are adopted in the embodiment, a plurality of support assemblies are arranged at the bottom of the beam 1 at equal intervals along the length direction, and purlins 5 are arranged on the side opposite to the support assemblies along the length direction.

[0038] As shown in Figure 3 , the support assembly comprises a vertical column 2, the top of the vertical column 2 is fixed with a diagonal beam 3, the lower part of the side wall of the vertical column 2 is fixed with a horizontally arranged connecting plate 4, and the end away from the vertical column 2 of the connecting plate 4 is fixed with the diagonal beam 3. The diagonal beam 3 and the vertical column 2 in the embodiment are both H-shaped section profiles, the connecting plate 4 is connected with the horizontal plane of the diagonal beam 3 and the vertical column 2 respectively, and the support assembly is an integral molding type structure. The horizontal plane away from the connecting plate 4 of the diagonal beam 3 is bolted or welded with the beam 1.

[0039] The inclination angle of the inclined beam 3 (i.e., the angle between the inclined beam 3 and the vertical line) is greater than 70° and less than 90°, so that the installation angle of the photovoltaic panel 10 tends to be vertical. The photovoltaic module is installed on the photovoltaic support, and the inclination angle of the photovoltaic module is consistent with the inclination angle of the inclined beam 3. When wind acts on the photovoltaic panel 10, the nearly vertical surface can better block the direct impact of the wind than a normal inclined surface.

[0040] like Figure 4 As shown, the purlin 5 is a C-shaped purlin. One side wall of the purlin 5 is bolted to the photovoltaic module, and the other side wall of the purlin 5 is bolted to the crossbeam 1. If the purlin 5 is not long enough, multiple purlins 5 can be spliced ​​to extend it. Two adjacent purlins 5 are connected and fixed by purlin brackets 11. The purlin brackets 11 are respectively connected to the two purlins 5 by bolts.

[0041] A fixing plate is welded to the bottom of the column 2, which is connected and fixed to the concrete foundation 6 through the fixing plate. The concrete foundation 6 is buried in the foundation pit. The support assembly provided in this embodiment is a single-row structure, that is, a single column structure in the inclination direction, which saves pile foundation, has a simple structure, and is easy to install.

[0042] The fence-type photovoltaic support provided in this embodiment has a whole row of photovoltaic modules installed on a support module with a large inclination angle, such as Figure 5 and Figure 6 As shown, it can achieve the effect of enclosing the photovoltaic field and form a barrier. When the wind comes, it can effectively disperse the wind pressure, just like a windbreak. After the wind hits the photovoltaic panels installed on the photovoltaic bracket, part of the wind is diverted upwards and to both sides, reducing the wind speed inside the photovoltaic area, thereby reducing the wind load borne by other photovoltaic brackets in the photovoltaic field, and playing a good enclosing role.

[0043] Example 2

[0044] A fence-type photovoltaic support, such as Figure 7 As shown, the technical solution in this embodiment is basically the same as that in embodiment 1, except that: a roller assembly 8 is further provided in this embodiment, so that the photovoltaic assembly can move to both sides.

[0045] like Figure 10 As shown, in this embodiment, a U-shaped guide rail 7 is provided on the crossbeam 1, and the crossbeam 1 and the guide rail 7 are an integrally formed structure. A plurality of roller assemblies 8 are installed at the bottom of the purlin 5, such as Figure 9As shown, the roller assembly 8 includes a connector and a roller 804. The connector includes a square groove 801. The bottom of the square groove 801 is provided with an opening. Two vertical plates 802 are symmetrically arranged at the opening. A roller 804 is provided between the two vertical plates 802. The roller 804 is rotatably connected to the two vertical plates 802 via a rotating shaft. When the roller assembly 8 is on the guide rail 7, the two sides of the bottom opening of the square groove 801 contact the top of the guide rail 7. The connector is an integrally formed structure. The top wall of the square groove 801 is provided with a threaded hole 803, which is fixed to the side wall of the purlin 5 by bolts, as shown in FIG. Figure 12 shown.

[0046] The guide rails 7 and roller assemblies 8 are provided to drive the purlins 5 to move, and at the same time drive the photovoltaic components to move, so that it can be used as a fence of the photovoltaic area and as a passage door to the photovoltaic area.

[0047] The length of the beam 1 is greater than the length of the purlin 5, as shown in FIG. Figure 10 As shown, the two ends of the beam 1 are fixed with limit plates 101 to prevent the roller assembly 8 from sliding off the guide rail 7. Two groups of photovoltaic brackets can be installed at a certain distance. When the photovoltaic components on the two groups of photovoltaic brackets are pushed close to each other, the access door to the photovoltaic field area is closed (such as Figure 14 As shown), when they move away from each other, the access door to the photovoltaic field area opens (as shown Figure 13 shown).

[0048] A limit block 9 is placed at one end of the beam 1 away from another set of photovoltaic brackets, such as Figure 11 As shown, a limiting bolt 901 is provided on the limiting block 9, and a limiting hole 102 is provided on the bottom wall of the beam 1. Figure 10 When the access door to the photovoltaic field needs to be closed, the two sets of photovoltaic modules on the photovoltaic brackets are pushed closer to each other, the limit block 9 is placed in the crossbeam 1, and the limit bolt 901 is tightened with the limit hole 102. Due to the obstruction of the limit block 9, the roller assembly 8 cannot slide, so the purlin 5 is fixed, and the photovoltaic module is also fixed, which can prevent the photovoltaic module from moving back and forth due to the influence of wind.

[0049] Traditional photovoltaic field fences and access gates require separate construction, which consumes additional land and material resources. However, the photovoltaic bracket provided in this embodiment uses guide rails and roller assemblies to allow the photovoltaic panels to move a certain distance to either side. This allows it to serve as both a photovoltaic field fence and an access gate, saving construction costs.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
