Description

TECHNICAL FIELD

[0002] In the field of renewable energy, the application of solar photovoltaic panels is increasingly widespread, but the severe weather conditions in areas with strong winds pose a serious challenge to their stable operation. Strong winds not only directly exert strong wind pressure on the surface of the photovoltaic panel, but also cause severe vibration through complex aerodynamic effects, accelerating structural fatigue, and even causing damage to the photovoltaic panel and supporting structure, affecting the safety and economy of the overall system. Although existing designs have focused on photoelectric efficiency and structural stability, they still fall short in dealing with the wind dynamic load vibration effect under strong wind pressure. Traditional fixed support systems are difficult to adapt to rapid changes in wind direction, and the added wind-blocking structure, while providing protection, may also be damaged due to excessive wind pressure. In recent years, although there have been attempts to optimize the layout, improve the support, or use intelligent control, these methods often face problems such as high cost, difficulty in implementation, or limited adaptability.

[0027] As Figures 1-4 Indicated, the device for reducing the vibration effect of solar photovoltaic panel wind load includes bottom support 1, support beam 2, damping assembly, safety cover 5 and photovoltaic panel 20.

[0028] Support beam 2 is fixed on bottom support 1 by bolt, and support beam 2 is provided with a plurality of damping assemblies and photovoltaic panels 20 are connected between two adjacent support beams 2 in turn.

[0029] The damping assembly comprises an elastic left arm 11, an elastic right arm 12, a bolt fixing cylinder 13, a bolt 3 and a nut 16. The elastic left arm 11, the elastic right arm 12 and the bolt fixing cylinder 13 are of an integrated structure, wherein the elastic left arm 11 and the elastic right arm 12 are both triangular ring-shaped and symmetrically connected to the two sides of the bolt fixing cylinder 13.

[0030] The upper end surface of the support beam 2 is provided with a clamping assembly comprising fixed clamping teeth 6 and a track plate 7, both of which are vertically fixed on the upper end surface of the support beam 2, and a clamping opening is formed between the fixed clamping teeth 6 and the track plate 7, and the track plate 7 is provided with a splicing track groove 8 towards the side of the damping assembly. The safety cover 5 comprises a top plate 51 and two side plates 52 provided on both sides of the top plate 51, and a clamping plate 53 is arranged outside the two side plates 52 (with the side towards the bolt 3 as the inner side and the side away from the bolt 3 as the outer side), and the clamping plate 53 is clamped in the splicing track groove 8.

[0031] The fixed clamping teeth 6 are provided with through grooves for avoiding the elastic left arm 11 and the elastic right arm 12, and the elastic left arm 11 and the elastic right arm 12 pass through the through grooves and are arranged in the clamping opening. After the safety cover 5 is connected with the clamping assembly, the two side plates 52 press the elastic left arm 11 and the elastic right arm 12 tightly in the clamping opening, and the top plate 51 abuts against the upper end surface of the bolt 3. The top plate 51 is a trapezoidal plate with a wide upper end and a narrow lower end. This structure not only abuts against the bolt 3, but also provides sufficient elastic space for the elastic left arm 11 and the elastic right arm 12, effectively disperses and absorbs wind load, greatly reduces vibration effect, and guarantees long-term stable operation of the photovoltaic panel. The bolt 3 is a high-strength bolt.

[0032] The damping assembly and the support beam 2 are precisely fixed and tightly locked by the high-strength bolt 3, thereby building a stable connection foundation and effectively resisting wind load impact. In addition, the innovative rigid safety cover 5 is designed to seamlessly connect the unique splicing track and the support beam 2, which not only facilitates installation but also stably locks, fundamentally solves the problem of bolt 3 loosening, and further improves the installation stability. The overall structure design greatly improves the wind pressure resistance performance, guarantees the normal operation of the photovoltaic panel 20 in extreme environments, prolongs the service life, and reduces the maintenance cost. Therefore, the utility model not only solves the technical difficulties of photovoltaic panel installation in high wind pressure areas, but also provides a solid backing for the stable operation of the solar power generation system, and exhibits significant technical progress and wide application potential.

[0033] As a preferred scheme, the abutting surfaces of the photovoltaic panel 20, the support beam 2 and the track plate 7 are paved with flexible material 9 such as elastic rubber, which has good damping effect and improves the damping effect of the photovoltaic panel 20.

[0034] The bottom support 1 is a plate structure, and as a preferred solution, the outer side (the side facing the side where the photovoltaic panel is located is the outer side) of the upper end of the support beam 2 is also provided with an extension plate A14 to increase the support area of the photovoltaic panel 20; the outer side of the lower end of the support beam 2 is provided with an extension plate B15 to increase the connection area of the support beam 2 and the bottom support 1.

[0035] Finally, it should be pointed out that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not limiting.
