[0028] The stable wind-resistant structure consists of a stabilizing mechanism, a stabilizing cable 302, and a stabilizing base 301. The first longitudinal rod 304 is rotatable relative to the support column 303, causing the first longitudinal rod 304 to form an angle relative to the support column 303. The load-bearing cable 105 moves synchronously with the first longitudinal rod 304, thus changing the tilt angle of the photovoltaic modules installed on the load-bearing cable 105, achieving tracking of the photovoltaic modules. The two ends of the stabilizing cable 302 are connected to the stabilizing base 301 at the beginning and end of each row, achieving the effect of reducing wind vibration and resisting negative winds, thereby improving the overall stability of the photovoltaic system.

The stable cable 302 passes through the U-shaped opening of the lower U-shaped lock 308, and the stable cable 302 is limited.

The load-bearing cable 105 passes through the U-shaped openings of the upper U-shaped locks 307, and the load-bearing cable 105 is limited.

[0032] Specifically, in an optional embodiment, as shown in Figure 3 As shown, the stabilizing mechanism further comprises a second longitudinal rod 306, and a plurality of reinforcing rods are connected between the first longitudinal rod 304 and the second longitudinal rod 306. By arranging the second longitudinal rod 306 and the plurality of reinforcing rods, the first longitudinal rod 304 is not easy to break and deform when rotating.
