Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic power generation, and in particular to a corrosion-resistant structure for the pile foundation of a photovoltaic project under desert conditions. Background Technology
[0002] Photovoltaic projects are widely used in desert and arid regions. Due to the unique environmental characteristics of desert areas, such as high temperatures, dryness, and sandstorms, the corrosion prevention of photovoltaic project pile foundations presents a severe challenge. Traditional anti-corrosion technologies are insufficient to meet the needs of the desert environment, leading to susceptibility to corrosion of pile foundations, shortened service life, and impacting the stability and reliability of photovoltaic projects. Analysis of operational projects and geological survey reports in desert areas reveals that the most susceptible area to corrosion in the pile foundations of photovoltaic projects in desert regions is the surface layer in contact with the air. Due to the large diurnal temperature range in desert areas, the metal temperature of the pile foundation drops rapidly in this area. Moisture in the air easily condenses on the steel piles, and this condensation seeps down the pile foundation. This creates a complex environment involving the pile, air, desert soil, and moisture, causing electrochemical corrosion. Furthermore, the existing structure of the steel piles results in varying corrosion rates at the same depth, which, over time, can easily lead to pile collapse. Utility Model Content
[0003] The present invention aims to provide a corrosion-resistant structure for the pile foundation of photovoltaic projects under desert conditions, so as to solve the problem of uneven corrosion at different depths of existing steel piles.
[0004] This solution provides a corrosion-resistant structure for the pile foundation of a photovoltaic project under desert conditions, comprising an H-beam, a skirt component fixedly connected to the H-beam, a skirt attachment on the skirt component, and the skirt component connected to the H-beam through the skirt attachment.
[0005] Furthermore, the umbrella skirt component is 1mm thick, with an outer side length of 200mm at the large end and an outer side length of 110mm at the small end.
[0006] Furthermore, the length of the umbrella skirt attachment is 200-300mm.
[0007] Furthermore, the umbrella skirt component is made of hot-dip galvanized steel.
[0008] Furthermore, the umbrella skirt component is made of plastic.
[0009] Furthermore, the umbrella skirt attachments are made of plastic. Plastic itself has a certain strength, allowing it to penetrate 10cm to 20cm into the desert while still fitting snugly against the H-beam.
[0010] The working principle and beneficial effects of this scheme are as follows: The umbrella-shaped skirt components and their attachments are fitted into H-beams and then driven into the ground. Note that the lower part of the attachment structure should be driven 10cm to 20cm into the soil. When condensation occurs at night, the condensate on the upper part flows outward through the umbrella-shaped skirt components, preventing it from accumulating near the steel structure. This prevents the formation of an electrochemical reaction structure between the steel structure, water, air, and desert soil. Therefore, the corrosion resistance of the steel piles remains essentially consistent at different depths. Attached Figure Description

[0012] Figure 2 for Figure 1 The main view;
[0013] Figure 3 for Figure 1 Top view. Detailed Implementation
[0014] The following detailed explanation illustrates the specific implementation methods:
[0015] The reference numerals in the accompanying drawings include: H-beam 1, umbrella skirt component 2, and umbrella skirt attachment 3.
[0016] The basic implementation examples are as follows: Figures 1-3 As shown: A corrosion-resistant structure for a photovoltaic project pile foundation under desert conditions includes an H-beam 1, on which a skirt component 2 is fixedly connected. The skirt component 2 is made of hot-dip galvanized steel, with a thickness of 1mm, an outer side length of 200mm at the large end, and an outer side length of 110mm at the small end. A skirt attachment 3 is provided on the skirt component 2. The skirt attachment 3 is a hollow "H" shape, made of plastic, and has a length of 200-300mm. The skirt component 2 is connected to the H-beam 1 through the skirt attachment 3.
[0017] The umbrella skirt component 2 and umbrella skirt attachment 3 are fitted onto the H-beam 1. The umbrella skirt attachment 3 can be welded to the H-beam 1, or a sealing ring can be first fitted onto the H-beam 1 before fitting the umbrella skirt attachment 3 to secure it. Then, the pile is driven into the ground. Note that the lower part of the attachment structure should be driven into the ground to a depth of 10cm–20cm. When condensation occurs at night, the condensate on the upper part flows outward through the umbrella skirt component 2, preventing it from accumulating near the steel structure. This prevents the formation of an electrochemical reaction structure between the steel structure, water, air, and desert soil. Therefore, the corrosion resistance of the steel pile is essentially consistent at different depths.
