Description

Technical Field

[0001] The utility model belongs to the technical field of adjustable photovoltaic brackets, and in particular relates to a three-column type adjustable photovoltaic bracket. Background Art

[0002] At present, adjustable photovoltaic brackets are usually supported by multiple columns. These columns are arranged in a row in the east-west direction, and a rotatable main beam is horizontally mounted on the top of the columns. All photovoltaic modules, purlins and diagonal braces for installing photovoltaic modules are all fixedly installed on the main beam, and push rods, diamond jacks or disc gears are used to promote the rotation of the main beam to achieve the purpose of angle adjustment.

[0003] However, in some existing adjustable photovoltaic brackets, the main beam and the column are vertically connected, and there is no corresponding structure between the main beam and the column to adjust the angle between the two, so that the adjustable photovoltaic bracket has no terrain adaptability; in another part of the existing adjustable photovoltaic brackets, the main beam and the column are connected by a specific structure. This specific structure has a certain rotation function in the east-west direction, which can change the angle between the main beam and the column, but its angle adjustment ability is poor.

[0004] In addition, the adjustable photovoltaic bracket is greatly affected by the quality of foundation construction. If the foundation construction quality is not good, the error will be magnified when the column is installed on the foundation, resulting in the top of the column not being in a straight line, which in turn makes it difficult to install the main beam. On-site installation requires a lot of manpower and material resources to correct the quality of foundation construction. In addition, the installation inconvenience caused by poor foundation construction quality is often accompanied by unreasonable installation methods, which worsens the stress of the bracket structure and increases safety risks.

[0005] At the same time, all the columns of the adjustable photovoltaic support are in a straight line, and its east-west load-bearing capacity and stability are acceptable, but its north-south rotation can only be stabilized by structures such as drive arms, push rods or jacks. It has poor stability and can be easily damaged by wind. Utility Model Content
