Description

Technical Field

[0001] This utility model relates to a spiral anchor foundation structure for rapid leveling of photovoltaic brackets. Background Technology

[0002] With the rapid development of the global new energy industry, the scale of photovoltaic power plant construction is constantly expanding. Photovoltaic sites are often located in areas with complex terrain such as mountains, slopes, and wastelands. These areas generally have problems such as uneven terrain and large changes in ground elevation.

[0003] Spiral anchors, a common type of foundation for photovoltaic (PV) systems, offer advantages such as convenient construction and minimal environmental impact. Traditional spiral anchors have a fixed, integrated top connector and anchor rod. During installation, precise control of the screw-in depth of each anchor is crucial to ensure consistent height across all anchor foundations, thus meeting the requirements for level installation of PV systems. However, factors such as undulating terrain and uneven soil density make it difficult to achieve uniform top height with traditional spiral anchors in a single screw-in operation. This often results in connector height deviations after installation, necessitating extensive on-site cutting (cutting down excessively tall anchor rods) or shimming (placing steel plates or concrete blocks under excessively short connectors) to adjust the height.

[0004] The above-mentioned leveling method has the following problems: First, the construction efficiency is extremely low. On-site cutting requires professional equipment and personnel, and the elevation work requires repeated measurement and adjustment, which greatly prolongs the construction period. Second, the installation accuracy of the photovoltaic bracket is difficult to guarantee. Errors are prone to accumulate during the cutting or elevation process, resulting in the flatness of the photovoltaic bracket installation surface not meeting the design requirements, which affects the installation quality and service life of the photovoltaic modules. Third, the cost is high. The additional labor, auxiliary materials (such as pads and cutting materials) consumption, as well as the management costs caused by the extended construction period, all increase the construction investment of the photovoltaic power station.

[0005] Therefore, there is an urgent need for a spiral anchor foundation structure that can adapt to uneven terrain and achieve rapid leveling, in order to solve the problems of fixed height and difficulty in leveling traditional structures, and meet the needs of efficient, precise and low-cost construction of photovoltaic power plants.

The pin 6 is made of No. 45 steel to improve the overall structural strength of the pin 6.

[0042] Furthermore, the surfaces of anchor bolt 1, anchor plate 2, and top connector 5 are all hot-dip galvanized, with a galvanized layer thickness of 85μm.

[0043] In this embodiment, the entire outer surface of the anchor rod 1, anchor plate 2, and top connector 5 is hot-dip galvanized with a zinc coating thickness of 85μm to improve the corrosion resistance of the anchor rod 1, anchor plate 2, and top connector 5.

[0044] In use, first use the spiral anchor screwing device to screw the anchor rod 1 of the spiral anchor into the designated position in the photovoltaic field, ensuring that the length of the top connecting section of the anchor rod 1 protruding above the ground meets the adjustment requirements. Then, fit the sleeve 7 of the top connector 5 onto the smooth section 3 at the top of the spiral anchor rod 1 to achieve initial positioning of the spiral anchor height. Next, use a level to measure the height, move the top connector up and down to the target height, and align the second through hole 8 on the sleeve 7 with the first through hole 4 on the smooth section 3 at the top of the anchor rod 1. Then, insert the pin 6 through the aligned second through hole 8 and the second through hole 8. Finally, insert the cotter pin 11 into the pin hole 10 to lock the pin 6.
