Wherein Figure 1 A photovoltaic support in a common structure in the prior art is shown, the photovoltaic support 1 is provided with a plurality of longitudinally extending inclined beams 5 and a plurality of purlins 3 (i.e. cross beams) vertically intersecting and fixed above the plurality of inclined beams, the inclined beams 5 are supported below by columns 4, the bottom of the column 4 is connected with a foundation 6, and the component pressing block fixing device 1 is installed on the purlin 3.

[0039] The component pressing block fixing device 1 comprises a lower pressing block 12 supported on the purlin, an upper pressing block 11 arranged above the lower pressing block 12, and a bolt assembly. The bottom of the upper pressing block 11 is provided with a threaded hole 114, and the bolt assembly comprises a bolt 13, the bolt 13 passes through the purlin 3 from bottom to top and is connected with the threaded hole 114. The bolt 13 is fixed on the lower side of the purlin, and the lower pressing block 12 and the upper pressing block 11 are matched to clamp the photovoltaic component frame. Since the bolt is fixed on the lower side of the purlin, the component pressing block fixing device and the photovoltaic component can be fixed, and vice versa, the bolt can be loosened on the lower side of the purlin during disassembly, so that the problem that the construction personnel has to step on the component during construction can be avoided, the safety of the construction personnel and the physical integrity of the photovoltaic component can be effectively ensured, and the component can be conveniently installed and dismounted, time and manpower can be saved, and the construction period of the project can be shortened, thereby solving the problem that the construction period of the traditional photovoltaic power station is long, resulting in high cost of the photovoltaic power station.

Although a clearance is provided between the bottom portion and the side portion of the slide rail and the slide groove to facilitate relative sliding, the clearance between the bottom portions can be relatively large so that the upper pressing block can move downward until the pressing portion presses the upper side of the frame.

[0043] Specifically, the upper pressing block 11 includes a mounting portion 111 and a pressing portion 112, the mounting portion 111 passes through the gap between two adjacent photovoltaic modules, the pressing portion 112 protrudes outward from the top of the mounting portion, and the pressing portion 112 is used to press on the upper side of the frame, and the sliding rail 113 is connected with the bottom surface of the mounting portion.

When disassembled, the eye nut is withdrawn from the bolt, and the gasket and the nut are removed, so that the connection relationship between the components, the pressing block and the photovoltaic support is convenient to disassemble.

[0045] Preferably, the upper pressing block 11 and the lower pressing block 12 are profiled materials, such as aluminum alloy profiled materials.
