Description

Photovoltaic spiral steel pile Technical Field The utility model relates to the field of building construction, in particular to a photovoltaic spiral steel pile. Background In a photovoltaic power generation system, a photovoltaic spiral steel pile is used as an important basic supporting structure and is widely applied to the installation and fixation of a photovoltaic bracket. Conventional photovoltaic screw steel piles are typically of a single helical structure that is screwed into the ground by helical blades to provide support. However, in practical applications, particularly in areas with relatively soft soil properties, conventional photovoltaic spiral steel piles have a number of problems. In the pile-down process of the traditional photovoltaic spiral steel pile, due to the fact that an effective reinforcing device is lacked structurally or the reinforcing device is directly exposed outside, the convex reinforcing part can increase the resistance between the pipe pile and soil when the pile is down, and the pile-down process is laborious. Disclosure of utility model The utility model aims to provide a photovoltaic spiral steel pile, which is used for solving the technical problem that the convex reinforcing part of the traditional photovoltaic spiral steel pile can increase the resistance between a pipe pile and soil in the pile-discharging process, so that the pile-discharging process is laborious. In order to achieve the purpose, the technical scheme adopted by the utility model is that a photovoltaic spiral steel pile is provided, and the photovoltaic spiral steel pile comprises: The tubular pile is of a hollow structure, an inner thread and a groove are formed in the inner wall of the tubular pile, and a plurality of through holes are formed in the periphery of the tubular pile; The reinforcing part comprises a connecting plate and reinforcing nails arranged on the connecting plate, the connecting plate is positioned in the tubular pile, the reinforcing nails are in sliding fit in through holes of the tubular pile, and before the tubular pile is placed, the reinforcing nails are hidden in the tubular pile; the connecting rod, the outside of connecting rod is provided with the external screw thread, the connecting rod top is provided with the connecting seat of being connected with photovoltaic support, the bottom of connecting rod is provided with toper guide structure, the connecting rod with tubular pile screw thread fit. In one embodiment, the tubular pile is provided with a plurality of reinforcing parts, and the reinforcing parts are uniformly arranged around the central line of the tubular pile. In one embodiment, the tail ends of the reinforcing nails are pointed, and the reinforcing nails are made of high-strength corrosion-resistant metal materials. In one embodiment, the outer wall of the tube stake is provided with an anti-corrosion coating. In one embodiment, the anti-corrosion coating is internally and outwards provided with an inorganic zinc-rich primer layer, an epoxy cloud iron intermediate paint layer and an acrylic polyurethane top paint layer in sequence, and the thickness ratio between the coating layers is 1:1.5:2. The above-mentioned one or more technical solutions in the embodiments of the present utility model at least have the following technical effects or advantages: According to the photovoltaic spiral steel pile provided by the embodiment of the utility model, the reinforcing part is arranged, after the pile is completely arranged, the conical guide structure at the bottom of the connecting rod converts downward pressure into outward extrusion force by utilizing the threaded cooperation of the connecting rod and the pile, so that the connecting plate is pushed to move outwards, and the reinforcing nails originally hidden in the pile are extended out and inserted into soil around the pile, thereby effectively reinforcing the pile, remarkably improving the stability of the photovoltaic spiral steel pile in a soft soil area, ensuring that the photovoltaic support can firmly support the photovoltaic plate, and ensuring the normal operation of a photovoltaic power generation system. And before the pile is driven, the reinforcing nails are hidden inside the pipe pile, so that the pile driving of the pipe pile is prevented from being blocked by the protruding reinforcing nails, the resistance of the pipe pile during pile driving is effectively reduced, the pile driving process of the pipe pile is more labor-saving compared with the traditional spiral steel pile, the labor intensity of constructors is reduced, and the construction efficiency is improved.
