Description

Technical Field

[0001] This utility model relates to the field of photovoltaic booster station construction technology, specifically to a modular prefabricated booster station. Background Technology

[0002] A photovoltaic (PV) booster station is a crucial component of a PV power generation system. Its primary function is to convert the low-voltage direct current (DC) generated by PV modules into high-voltage alternating current (AC) that meets grid standards, enabling successful grid connection. This process involves multiple aspects, including voltage transformation, inversion, control, and protection, ensuring the safe and stable output of PV power. The booster station foundation is typically constructed using cast-in-place concrete, with pre-installed connectors for subsequent installation of inverters and other equipment. However, for PV power generation systems built in desert sites, the presence of aeolian sand presents significant challenges. Aeolian sand is characterized by its uniform particle size, lack of cohesion, loose structure, poor plasticity, and poor gradation. Furthermore, its low cohesion, high compressibility, and poor self-stability make it difficult to construct the booster station foundation using cast-in-place concrete. During the drilling of holes for the reinforcing cage and subsequent concrete pouring, the surrounding aeolian sand can easily collapse into the pile holes, affecting the quality of the pile foundation construction. Additionally, cast-in-place concrete involves extensive wet work, resulting in poor environmental impact, long construction periods, and high pile foundation costs. Utility Model Content

The mounting plate 703 and positioning column 701 are pre-set according to the arrangement of each piece of equipment. During the hoisting process, the mounting plate 703 can be rotated to adjust the position of the connecting column 801, so as to facilitate the connection between the connecting column 801 and the inverter and other equipment. After the position of the mounting plate 703 is determined, the locking sleeve 901 is rotated to fix the position of the mounting plate 703, thereby fixing the position of the connecting column 801. The inverter and other equipment are then connected to the connecting column 801 and fixed with the locking sleeve 1001.

[0060] In this embodiment, support columns 101 are inserted into the ground to provide support, and multiple sets of support columns 101 are connected by bottom connecting plate 202, top connecting plate 302, and reinforcing rod 402.
