Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic support brackets, in particular to a purlin support system for photovoltaic brackets. Background Art

[0002] Currently, photovoltaic modules are usually installed on 2×13 module frames.

[0003] According to the current photovoltaic support design specifications, when the purlin width is greater than 4m, it is recommended to add lateral support systems such as straight braces and diagonal braces in the mid-span. The lateral support system should act directly on the compressed part of the purlin.

[0004] At present, the mainstream scheme of purlin support system is as follows: the stability of the upper flange is constrained by the component frame. The stability of the lower flange is constrained by the straight brace and the diagonal brace. The straight brace and the diagonal brace are generally made of 10mm diameter round steel, and the support rod is made of 30mm diameter and 2mm wall thickness steel pipe. The diagonal brace needs to be bent twice before connecting with the purlin, and the processing process is relatively complicated. During the on-site installation process, there is also the problem of difficulty in installation. Utility Model Content

[0037] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0038] First see Figure 1 , Figure 1 FIG. 1 is a schematic structural diagram of an embodiment of a purlin support system for a photovoltaic support according to the utility model. Figure 1 As shown, the system includes four purlins 1 arranged at intervals. 26 component frames 2 for placing photovoltaic components are connected to the upper edge of the purlin 1. The component frames 2 are divided into two rows, with 13 components in each row. The first row of component frames 2 is connected to the upper ( Figure 1 The second row of component frames 2 are connected to the lower ( Figure 1 On two purlins 1 in the direction of the center.

[0039] Four oblique beams 3 are connected to the lower edges of the four purlins 1, and the arrangement direction of the oblique beams 3 is perpendicular to the purlins 1. Those skilled in the art can determine the spacing and number of the oblique beams 3 according to the length of the purlins 1.

[0040] See next Figure 2 and Figure 3 And continue to read Figure 1 , Figure 2It is a structural schematic diagram of another embodiment of the purlin support system for a photovoltaic support of the utility model. Figure 3 It is a schematic diagram of the structure of the connection between the purlin and the first diagonal brace. Figure 2 The structure of the upper edge of the purlin 1 is shown. Figure 1 and Figure 2 As shown, two first inclined braces 41 and two second inclined braces 42 are arranged on the upper edge of the purlin 1 between the two inclined beams 3. A first straight brace 43 is connected between the two middle purlins 1.

[0041] Specifically, since the two upper purlins 1 are connected to the first row of component frames 2, and the two lower purlins 1 are connected to the second row of component frames 2, that is, the two middle purlins 1 provide connection strength only through the diagonal beams 3. In order to further improve the connection strength of the two middle purlins 1, two first straight braces 43 are connected to the upper edges of the two middle purlins 1 between every two diagonal beams 3. In order to avoid interference between the first straight braces 43 and the component frames 2, the first straight braces 43 can be connected to the inner wall of the upper edge of the purlin 1 by bolts 6.

[0042] The two first inclined braces 41 are symmetrically arranged, and each first inclined brace 41 connects the two upper purlins 1. The span of the first inclined brace 41 is between the adjacent inclined beams 3 and the first straight brace 43. In order to avoid interference between the first inclined brace 41 and the component frame 2, the span of the first inclined brace 41 can be within the two side edges of the corresponding component frame 2.

[0043] The two second inclined braces 42 are symmetrically arranged, and are symmetrically arranged with the two first inclined braces 41. Each second inclined brace 42 connects two purlins 1 below.

[0044] like Figure 3 As shown, the first diagonal brace 41 and the second diagonal brace 42 can be directly connected to the upper edge of the purlin 1 by bolts 6 .

[0045] See next Figure 4 and Figure 5 And continue to read Figure 1 , Figure 4 This is a structural schematic diagram of another embodiment of the purlin support system for a photovoltaic support of the utility model; Figure 5 It is a schematic diagram of the structure of the connection between the purlin and the third diagonal brace. Figure 4 The figure shows the connection structure of the lower edge of the purlin. Figure 1 and Figure 4 As shown, the lower edge of the purlin 1 in the middle of two adjacent inclined beams 3 is connected with a second straight brace 53. The second straight brace 53 connects four purlins 1. Two symmetrically arranged third inclined braces 51 and two symmetrically arranged fourth inclined braces 52 are arranged between two adjacent inclined beams 3.

[0046] The two third inclined braces 51 may be symmetrically arranged relative to the second straight brace 53. Each third inclined brace 51 connects the lower edges of the two upper purlins 1. Therefore, the span of the third inclined brace 51 may be between the inclined beam 3 and the second straight brace 53.

[0047] The two fourth inclined braces 52 are symmetrically arranged relative to the second straight braces 53, and are also symmetrically arranged with the third inclined braces 51. Each fourth inclined brace 52 is connected to two purlins 1 below.

[0048] like Figure 4 As shown, the third oblique brace 51 , the fourth oblique brace 52 and the second straight brace 53 can be directly connected to the lower edge of the purlin 1 by bolts 6 .

[0049] The second straight brace 53 can further improve the connection strength of the four purlins 1 on the basis of the inclined beam 3. The third inclined brace 51 and the fourth inclined brace 52 can support the purlin 1, thereby improving the reliability of the support system.

[0050] In addition, the first oblique brace 41, the second oblique brace 42, the third oblique brace 51, the fourth oblique brace 52, the first straight brace 43 and the second straight brace 53 can be made of thin-walled flat steel, angle steel, channel steel or C-shaped steel, thereby replacing the implementation method of using round steel in the relevant support system. In this way, the amount of steel used can be reduced.

[0051] Finally, the diagonal braces in the related support system are usually bent twice, which not only complicates the processing process but also makes installation difficult. However, the first diagonal brace 41, the second diagonal brace 42, the third diagonal brace 51, and the fourth diagonal brace 52 in the present application do not need to be bent, and are directly connected to the upper edge or the lower edge of the purlin 1 by bolts 6, thereby reducing the difficulty of installation.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this 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 make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
