Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a photovoltaic spiral steel pile. Background Technology

[0002] In photovoltaic (PV) power generation systems, helical steel piles are widely used as an important foundation support structure for the installation and fixation of PV brackets. Traditional PV helical steel piles are typically a single helical structure, providing support through helical blades screwed into the ground. However, in practical applications, especially in areas with relatively loose soil, traditional PV helical steel piles present numerous problems.

[0003] During the driving process of traditional photovoltaic spiral steel piles, the lack of effective reinforcement devices or the direct exposure of reinforcement devices in the structure can increase the resistance between the pile and the soil, making the driving process laborious. Utility Model Content

[0004] The purpose of this utility model is to provide a photovoltaic spiral steel pile to solve the technical problem that the protruding reinforcing components of traditional photovoltaic spiral steel piles increase the resistance between the pipe pile and the soil during the pile driving process, resulting in a laborious pile driving process.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a photovoltaic spiral steel pile, the photovoltaic spiral steel pile comprising:

[0006] The pipe pile has a hollow structure, and the inner wall of the pipe pile is provided with internal threads and grooves. Several through holes are provided around the pipe pile.

[0007] The reinforcement part includes a connecting plate and a reinforcing nail disposed on the connecting plate. The connecting plate is located inside the pipe pile, and the reinforcing nail is slidably engaged in the through hole of the pipe pile. Before the pile is driven, the reinforcing nail is hidden inside the pipe pile.

[0008] The connecting rod has an external thread on its exterior, a connecting seat at the top for connecting to the photovoltaic support, and a tapered guide structure at the bottom. The connecting rod is threadedly engaged with the pipe pile.

[0009] In one embodiment, the pipe pile is provided with a plurality of the reinforcing parts, which are evenly arranged around the center line of the pipe pile.

[0010] In one embodiment, the reinforcing nail has a pointed, conical end and is made of a high-strength, corrosion-resistant metal material.

[0011] In one embodiment, the outer wall of the pipe pile is provided with an anti-corrosion coating.

[0012] In one embodiment, the anti-corrosion coating consists of an inorganic zinc-rich primer layer, an epoxy micaceous iron oxide intermediate paint layer, and an acrylic polyurethane topcoat layer, arranged from the inside out, with a thickness ratio of 1:1.5:2 between each layer.

[0013] The above-described technical solutions in the embodiments of this utility model have at least the following technical effects or advantages:

[0014] The photovoltaic spiral steel pile provided in this embodiment of the utility model, by setting a reinforcement part, after the pipe pile is driven into the ground, uses the threaded engagement between the connecting rod and the pipe pile to convert the downward pressure into an outward compressive force through the conical guide structure at the bottom of the connecting rod, pushing the connecting plate outward. This causes the reinforcement nails, which were originally hidden inside the pipe pile, to extend and insert into the soil around the pipe pile, thereby effectively reinforcing the pipe pile. This significantly improves the stability of the photovoltaic spiral steel pile in areas with loose soil, ensuring that the photovoltaic bracket can stably support the photovoltaic panels and guarantee the normal operation of the photovoltaic power generation system.

[0015] Furthermore, before the pile is driven, the reinforcing nails are hidden inside the pipe pile, which avoids the protruding reinforcing nails from obstructing the driving of the pipe pile. This effectively reduces the resistance when driving the pipe pile, making the driving process of the pipe pile less labor-intensive than that of traditional spiral steel piles, reducing the labor intensity of construction workers and improving construction efficiency.

[0029] Please see Figures 1 to 6This application provides a photovoltaic spiral steel pile, including a pipe pile 1, a reinforcing part 2, and a connecting rod 3. The pipe pile 1 has a hollow structure, with internal threads 11 and grooves 12 on its inner wall, and several through holes 13 around its perimeter. The reinforcing part 2 includes a connecting plate 21 and reinforcing nails 22 mounted on the connecting plate 21. The connecting plate 21 is located inside the pipe pile 1, and the reinforcing nails 22 are slidably fitted within the through holes of the pipe pile 1. Before the pile is lowered, the reinforcing nails 22 are concealed inside the pipe pile 1. The connecting rod 3 has external threads 31 on its exterior, a connecting seat for connecting to a photovoltaic support is located at the top of the connecting rod 3, and a tapered guide structure 33 is located at the bottom of the connecting rod 3. The connecting rod 3 is threadedly engaged with the pipe pile 1.

[0030] The photovoltaic spiral steel pile provided by this utility model, during installation, first drives the pipe pile 1 into the ground at the installation location. Since the reinforcing nail 22 is hidden inside the pipe pile 1, protruding reinforcing nails 22 are prevented from obstructing the driving of the pipe pile 1. After the pipe pile 1 is driven into the ground, as... Figure 2 As shown, the connecting rod 3 is screwed into the pipe pile 1 through a threaded connection. When the connecting rod 3 moves downward, the tapered guide structure 33 at the bottom of the connecting rod 3 acts as a guide, transforming the downward pressure originally exerted by the connecting rod 3 on the connecting plate 21 into an outward compressive force. Under this compressive force, the connecting plate 21 moves outward, causing the reinforcing nails 22, which were originally hidden inside the pipe pile 1, to extend and insert into the soil around the pipe pile 1, thereby reinforcing the pipe pile 1. Figure 5-6 As shown, the connecting plate 21 moves into the groove 12 on the inner wall of the pipe pile 1 (the groove 12 on the inner wall of the pipe pile 1 can accommodate the connecting plate 21, so that the connecting plate 21 will not obstruct the connecting rod 3 from penetrating into the pipe pile 1). Then, the photovoltaic panel mounting frame can be fixed to the connecting seat at the top of the connecting rod 3 to install the photovoltaic panel. This improves the stability of the photovoltaic spiral steel pile, making it particularly suitable for areas with relatively soft soil. Furthermore, before lowering the pipe pile 1, the reinforcing nail 22 is hidden inside the pipe pile 1, which reduces the resistance to lowering the pipe pile 1, making the process of lowering the pipe pile 1 more labor-saving compared to traditional spiral steel piles.

[0031] In one embodiment, the pipe pile 1 is provided with multiple reinforcing parts 2, which are evenly arranged around the center line of the pipe pile 1. By providing multiple reinforcing parts 2 on the pipe pile 1 and making them evenly arranged around the center line of the pipe pile 1, the pipe pile 1 can be reinforced from multiple directions. Compared with a single reinforcing part 2, this design can make the force borne by the pipe pile 1 more uniform in all directions, greatly enhancing the stability of the pipe pile 1. Especially in areas with loose soil, it can effectively prevent the pipe pile 1 from tilting or sinking due to uneven force, thereby providing a more stable support foundation for the photovoltaic bracket and ensuring the normal operation of the photovoltaic power generation system.

[0032] In one embodiment, the reinforcing nail 22 has a pointed, conical end and is made of a high-strength, corrosion-resistant metal material. This pointed, conical end design makes it easier to insert into the soil, reducing insertion resistance. Simultaneously, the high-strength, corrosion-resistant metal material (specifically stainless steel) ensures that the nail is not easily deformed or broken under significant external forces, enabling it to provide long-term, stable reinforcement. Corrosion resistance extends the service life of the nail, reducing the risk of performance degradation or even failure due to corrosion, thus lowering maintenance costs.

[0033] In one embodiment, the outer wall of the pipe pile 1 is provided with an anti-corrosion coating. This coating effectively prevents moisture, oxygen, chemicals, and other external environmental substances from eroding the pipe pile 1, slowing down its corrosion rate. During long-term use, this prevents the pipe pile 1 from thinning and losing strength due to corrosion, thereby ensuring its structural integrity and load-bearing capacity and extending the overall service life of the photovoltaic spiral steel pile.

[0034] Specifically, the anti-corrosion coating consists of, from the inside out, an inorganic zinc-rich primer layer, an epoxy micaceous iron oxide intermediate coat layer, and an acrylic polyurethane topcoat layer, with a thickness ratio of 1:1.5:2 between each layer. This multi-layered structure leverages the advantages of each layer to create a synergistic protective effect. The inorganic zinc-rich primer layer provides excellent adhesion and cathodic protection, offering fundamental corrosion protection for the pipe pile 1. The epoxy micaceous iron oxide intermediate coat layer increases the coating thickness and shielding performance, further preventing the penetration of corrosive media. The acrylic polyurethane topcoat layer possesses excellent weather resistance, chemical resistance, and decorative properties, protecting the intermediate coat layer.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
