Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, and in particular to a photovoltaic support anti-vibration base. Background Technology

[0002] Photovoltaics, or photovoltaic power generation, is a clean energy technology that uses the photovoltaic effect of semiconductors to directly convert sunlight into electrical energy. Based on the photovoltaic effect of semiconductor materials, when sunlight shines on a photovoltaic cell, the energy carried by photons is absorbed by the semiconductor, allowing electrons to gain enough energy to jump from the valence band to the conduction band, thereby generating electron-hole pairs. There is a built-in electric field inside the photovoltaic cell, which drives electrons and holes to move towards the two poles of the cell, thus creating a potential difference between the poles. When the positive and negative poles of the cell are connected by wires, current flows through them, thus realizing the conversion of light energy into electrical energy. When it is necessary to support and place the photovoltaic modules, a photovoltaic support structure is required.

[0003] Currently available photovoltaic (PV) support systems mainly consist of columns, beams, diagonal braces, and connectors. During use, these components are assembled to support the PV modules. However, under long-term exposure to alternating loads and environmental factors, critical parts of the support system are prone to structural fatigue, leading to micro-cracks that gradually propagate and ultimately cause component failure, affecting overall stability. To address these issues, existing technologies only select steel or aluminum alloys with good fatigue resistance and strictly control material quality testing to ensure compliance with relevant standards. However, no improvements have been made in vibration resistance, making the system susceptible to structural damage during vibrations, resulting in module failure. Utility Model Content

[0039] Working principle: When vibration occurs during use, the vibration is generated by the springs 5 ​​on both sides of the connecting rod 4 in the middle of the support column 3 fixed on the top surface of the base plate 1. The force is generated by the sliding block 6, which stretches the push rod 7 and pushes the sliding block 8 to move to the far side, thus compressing the spring 10. This cancels out the vibration and avoids damage to the photovoltaic device and waste of resources.
