Description

Technical Field

[0001] The utility model relates to the technical field of solar photovoltaic power stations, in particular to a flat single-axis sun-chasing bracket and a steel frame connection structure for a solar photovoltaic power station. Background Art

[0002] Photovoltaic modules, also known as solar panels, are the core part of solar power generation systems. Their function is to convert solar energy into electrical energy and send it to batteries for storage or to drive loads.

[0003] The flat single-axis sun-tracking bracket is a photovoltaic bracket whose main feature is that it can rotate along the sun's sunshine trajectory to maximize the capture of sunlight. This bracket rotates only on one axis, that is, the horizontal axis, and is parallel to the ground, so it is called "flat single axis". It allows the solar panel to rotate along one axis within a day so that it always faces the sun.

[0004] Photovoltaic modules are generally installed on flat single-axis sun-tracking brackets. The existing installation method is threaded connection. Photovoltaic modules rotate on the brackets for a long time under alternating loads, and the bolts are very likely to loosen, causing module damage and affecting power station operation. Secondly, bolt installation is inconvenient. The installation of a module requires three workers to work together at the same time. Two people tighten the bolts at the upper and lower ends, and one person holds the photovoltaic module. The installation efficiency is low, and stainless steel bolts are prone to sticking. When sticking, the bolts need to be cut off by equipment and replaced with new bolts, which reduces the installation speed and increases the investment cost of the power station.
