Abstract
Description
An adjustable photovoltaic cast-in-place pile column verticality monitoring and fixing device Technical Field
[0001] This utility model relates to the field of photovoltaic grouting pile technology, specifically to an adjustable monitoring and fixing device for the verticality of the lower column of a photovoltaic grouting pile. Background Technology
[0002] Driven by the "dual carbon" goals, photovoltaic power plants, as an important carrier of clean energy, are experiencing accelerated large-scale construction. Due to their strong bearing capacity and high stability, cast-in-place pile foundations have become one of the mainstream foundation types for photovoltaic support installation. The verticality of the support column, as the core component connecting the photovoltaic support and the cast-in-place pile foundation, directly determines the installation accuracy and power generation efficiency of the photovoltaic modules. When the verticality deviation of the column exceeds a critical value (usually allowing an error ≤0.5% H, where H is the column height), it not only leads to inconsistent tilt angles of the photovoltaic module array, reducing light energy reception efficiency, but also causes the support structure to bear asymmetrical stress, exacerbating structural fatigue damage, and in severe cases, even causing safety accidents such as support collapse.
[0003] In existing technologies, the measurement accuracy is insufficient, and most measurements rely on manual intermittent use of tools such as theodolites and plumb lines. These measurements are susceptible to interference from factors such as ambient light and human operation, resulting in high measurement errors. Furthermore, manual measurement at multiple locations is time-consuming and labor-intensive, making it difficult to meet the requirements of high-precision construction. Therefore, this device provides an adjustable monitoring and fixing device for the verticality of the photovoltaic cast-in-place pile column. Summary of the Invention
