Fig. 2 illustrates an example configuration of a stationary photovoltaic rack assembly 100. The fixed photovoltaic rack assembly 100 can include two adaptively fixed photovoltaic racks 10 arranged in parallel, shown as adaptively fixed photovoltaic racks 10a, 10b, respectively. The fixed photovoltaic rack assembly 100 may further comprise a purlin 20, the purlin 20 straddling the oblique beams 22a, 22b of the two adaptive fixed photovoltaic racks 10a, 10b and being commonly supported by the oblique beams 22a, 22b of the two adaptive fixed photovoltaic racks 10a, 10 b. The purlins 20 can be directly fixed on and supported by the oblique beams 22a and 22b of the self-adaptive fixed photovoltaic supports 10a and 10b through fasteners, and photovoltaic modules 30 are supported on the purlins 20.

In fig. 2, as an example, the fixed photovoltaic module assembly 100 may have two supporting foundations, the base 1 may be fixed on the foundations, the column 21 may be fixed on the base 1 by two through bolts, and the auxiliary plate 23 may be respectively inserted through the fan-shaped holes 113 and 123 of the base 1 and the through hole of the column 21 and fixed on the column 21 by the first fastening member 31 in the form of a bolt, for example, fixed on the inner connection plate of the column 21. The rakes 23 may be bolted to the top 215 of the column 21, for example, and the rakes 23, column 21 and rakes 24 are relatively fixed by the cooperation of the rakes 241, 242. The purlins 20 may be fixed to the sloping beams 23.

When the settlement difference occurs between the two pillar foundations, the two fasteners penetrating through the vertical plates 11 and 12 of the base 1, namely the first fastener 31 and the second fastener 32, are unscrewed, so that the inclined beam 23, the upright post 21 and the inclined strut 24 can integrally rotate along the first fastener 31 supported by the vertical plates 11 and 12 of the base 1 to release the internal stress of the bracket generated by the settlement difference, and further, the purline 20 and the photovoltaic module 30 on the upper portion of the inclined beam 23 are prevented from deforming when the settlement difference occurs between the pillar foundations, and the photovoltaic module 30 is protected from being damaged.

In view of the fact that foundation settlement is a gradual process, in practical application, the support assembly can be subjected to self-adaptive rotation by periodically loosening the first fastening piece and the second fastening piece and keeping the first fastening piece and the second fastening piece for a period of time for locking again, so that the internal stress of the support generated by the foundation settlement is released. The self-adaptive fixed photovoltaic support can still keep a good supporting effect on the photovoltaic module after the foundation generates uneven settlement, and normal power generation of the photovoltaic module is not influenced.

With the large-scale development of photovoltaic power station construction, the construction of photovoltaic power stations by utilizing coal mining subsidence areas becomes more and more common, so that the self-adaptive fixed photovoltaic support has wide application prospect.

Although the present invention has been described with reference to the preferred embodiments, it is not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. For example, the conversion methods in the different embodiments may be combined as appropriate. Therefore, any modification, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention, all without departing from the content of the technical solution of the present invention, fall within the scope of protection defined by the claims of the present invention.
