Description

Technical Field

[0001] The utility model relates to the technical field of supporting devices, and more specifically, to a counterweight-stabilized photovoltaic bracket. Background Art

[0002] In the field of photovoltaic power generation, the stability of photovoltaic brackets is crucial to the safe operation and power generation efficiency of photovoltaic panels. However, the existing counterweight-stabilized photovoltaic brackets have some shortcomings in ground stability, counterweight protection and angle adjustment, which affect the performance and life of the photovoltaic system.

[0003] First of all, existing photovoltaic brackets usually only fix the support frame to the ground through fixing rods. However, when the ground soil is relatively loose, the connection stability between the fixing rods and the ground is poor, which may cause the support frame to shift or tip over under wind load or other external forces, thereby affecting the support stability of the photovoltaic panel. This instability may cause damage to the photovoltaic panel and even affect the safe operation of the entire photovoltaic system.

[0004] Secondly, in existing devices, the counterweight is usually exposed to the outside, which can easily cause the counterweight to be corroded during long-term use, such as weathering and rusting, thereby affecting its stability and service life. In order to protect the counterweight, sealing protection is required, but the connection operation between the existing sealing bin body and the sealing cover is usually cumbersome and cannot be quickly disassembled and assembled. This cumbersome connection method not only increases the difficulty of maintenance, but may also lead to a decrease in sealing performance, thereby affecting the long-term stability of the counterweight and the overall performance of the bracket.

[0005] In addition, most existing brackets are of fixed structure design, which cannot be flexibly adjusted or can only adjust the angle of the photovoltaic panel. This design limits the adaptability of the photovoltaic panel to the angle of the sun, and may cause the photovoltaic panel to not always be at the optimal power generation angle, thereby affecting the power generation efficiency. Especially in different seasons and different time periods, the altitude and azimuth of the sun will change, and the fixed bracket cannot adapt to these changes, resulting in reduced power generation efficiency of the photovoltaic system at some times.
