[0002] Today, with the increasing prominence of pollution problems caused by the consumption of traditional fossil fuels, the development of new energy sources is receiving more and more widespread attention from society. Solar photovoltaic power generation, as a new and pollution-free new energy source, is being used more and more widely due to its green and environmentally friendly nature and simple production process. my country has built a large number of ground-mounted photovoltaic power stations in the western Gobi Desert, but due to the inability of local power grids to absorb and transmit excess electricity, the curtailment rate is high. Therefore, the eastern region, with its much larger electricity demand, has become the main battleground for the photovoltaic industry. Because the eastern region is densely populated and has limited land resources available for development, people have had to build photovoltaic power stations in mountainous and wasteland areas.

[0029] In this embodiment, the first tie rod 301 of the tie rod assembly 3 connects to the support leg seat 201 of one support leg assembly 2, and the second tie rod 302 connects to the support leg rod 202 of another support leg assembly 2; or, the first tie rod 301 of the tie rod assembly 3 connects to the support leg rod 202 of one support leg assembly 2, and the second tie rod 302 connects to the support leg rod 202 of another support leg assembly 2; or, the first tie rod 301 of the tie rod assembly 3 connects to the support leg seat 201 of one support leg assembly 2, and the second tie rod 302 connects to the support leg seat 201 of another support leg assembly 2. The first tie rod 301 and the second tie rod 302 provide support for either the support leg seat 201 or the support leg rod 202. It should be noted that, as... Figure 3 As shown, the side of the outrigger rod 202 is provided with a connecting end 205, which is fixed to the tie rod by fasteners. Specifically, the fasteners are bolts.

[0030] In one embodiment, such as Figure 3As shown, the first tie rod 301 and the second tie rod 302 both have a second connecting through hole 303 on their shafts, and fasteners are inserted into the second connecting through holes 303. After the lengths of the first tie rod 301 and the second tie rod 302 are adjusted, the second connecting through holes 303 of the first tie rod 301 and the second tie rod 302 are aligned accordingly, and fasteners are inserted to fix the first tie rod 301 and the second tie rod 302 in place.
