Description

Technical Field

[0001] The utility model belongs to the technical field of machinery, and particularly relates to an adjustable bracket. Background Technique

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect at the semiconductor interface. It mainly consists of three major parts: solar panels, controllers, and inverters. Among them, solar panels are the core components that receive light and convert light energy into electrical energy. In order to fully ensure the light energy utilization rate, it is necessary to maintain a large light-receiving area and a relatively vertical light-receiving angle during operation. Therefore, in the field of photovoltaic power generation, the bracket structure for carrying solar panels plays an important role, which is applicable to both the photovoltaic power generation system itself and the optical power prediction system.

[0003] In the prior art, photovoltaic brackets can be divided into three types: fixed type, tilt-adjustable type, and automatic tracking type. Their connection methods are generally two forms: welding and assembly. Fixed brackets are further divided into roof brackets, ground brackets, and water surface brackets; automatic tracking brackets are divided into single-axis tracking brackets and double-axis tracking brackets. Taking the double-axis tracking bracket with more degrees of freedom as an example, its typical structure consists of rear columns, front columns, cross beams, inclined beams, connectors, etc., and is connected by bolts and plastic wing nuts to form a framework. The battery components are connected to the bracket cross beam by pressing blocks to form a set of unit wholes. This structure has good stability and is particularly suitable for large-scale arranged solar panels, but the structure is relatively heavy, often bringing a large self-weight and installation cost in the optical power prediction system, and it is not convenient for replacement and maintenance.

After the angle of the first rotating shaft is adjusted, the second hydraulic rod can be used to push the top frame to complete the adjustment of the angle of the second rotating shaft. The present utility model can not only efficiently and multi-angularly achieve the adjustment function of the photovoltaic panel, but also has a relatively small bottom support structure, does not require a large bearing area, is convenient for installation, and can be used in a light power prediction system.
