[0002] In power systems, steel pipe poles are a common support structure, primarily used to support transmission lines. Steel pipe poles are generally made of metal, possessing good mechanical strength and stability. However, traditional installation methods often suffer from low efficiency due to the difficulty of drilling holes at high altitudes when installing stringer bolts on steel pipe poles. Furthermore, because some distribution poles have relatively thin arms, in actual use, the tightening of the bolts can sometimes cause localized instability in the pole arm. Utility Model Content

[0003] The purpose of this utility model is to provide a perforated structure for power steel pipe poles to solve the problems mentioned in the background art.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-2 This utility model provides a technical solution: a perforated structure for an electric steel pipe pole, including a round tube 1, which is welded into the through hole 3 of the steel pipe pole body 2. The round tube 1 extends along the axial direction of the through hole 3, ensuring its stability and firmness.

[0024] The two ends of the round tube 1 are aligned with the two ends of the steel pipe pole body 2, and the round tube 1 is used to install the hanging screws 4. The precise alignment of the two ends of the round tube 1 with the two ends of the steel pipe pole body 2 is not only aesthetically pleasing but also ensures the symmetry and balance of the overall structure. Furthermore, the main function of the round tube 1 is to install the hanging screws 4. The installation position and method of the hanging screws 4 are carefully designed to ensure that the wires or other related equipment can be safely and stably fixed to the steel pipe pole.

[0025] This perforated internal structure design of the power steel pipe pole not only improves the pole's load-bearing capacity and stability but also facilitates the installation and maintenance of power lines and other equipment. This structural design extends the pole's service life and enhances the overall safety of the power system. Furthermore, this design provides excellent wind resistance and corrosion resistance, ensuring good performance even in harsh environments.

[0026] Specifically, the circular tube 1 is made of high-strength steel, and its wall thickness is 1 / 2 to 2 / 3 of the steel pipe rod's wall thickness, ensuring its strength and durability. High-strength steel possesses excellent tensile strength and toughness, capable of withstanding large loads without deformation. To further ensure the structural strength and durability of the circular tube 1, its wall thickness is designed to be between 1 / 2 and 2 / 3 of the steel pipe rod's wall thickness. This wall thickness setting ensures the robustness of the circular tube 1 in practical applications while avoiding unnecessary material waste, thus meeting performance requirements while also considering economy. Through this meticulous design, the circular tube 1 can maintain stable performance in various harsh working environments, ensuring long-term reliability.

[0027] Specifically, both ends of the circular tube 1 are chamfered, with the chamfer depth being 1 / 4 to 1 / 3 of the wall thickness of the circular tube 1. This design is not only for aesthetic purposes, but more importantly, it effectively prevents stress concentration. By reducing stress concentration, the structural stability of the circular tube 1 is significantly improved, thereby ensuring its reliability and durability in various applications.

[0028] Specifically, the interior of the circular tube 1 is provided with at least one reinforcing rib 5 along its axial direction. The reinforcing rib 5 is welded to the inner wall of the circular tube 1 to enhance its structural strength and stability. Through this welding process, the reinforcing rib 5 is tightly bonded to the inner wall of the circular tube 1, ensuring the overall structural robustness and durability. Specifically, both ends of the circular tube 1 are provided with anti-slip grooves 6, which extend along the axial direction of the circular tube 1. This design effectively prevents the hanging screw 4 from slipping during installation, ensuring the reliability of the installation. This unique design concept aims to effectively prevent the hanging screw 4 from slipping during installation, thereby greatly improving the stability and reliability of the installation process. Through this meticulous design, the smoothness and safety of the entire installation process are ensured, while also improving the durability and service life of the overall structure.

[0029] Specifically, an anti-corrosion coating 7 is applied to the inner wall of the circular pipe 1. The thickness of this anti-corrosion coating 7 is strictly controlled between 0.1 mm and 0.3 mm to ensure that it is neither too thick, affecting the normal use of the pipe, nor too thin, losing its protective effect. The choice of material for the coating 7 is very particular; it can be an epoxy resin layer or a galvanized layer. Both materials have good anti-corrosion properties, effectively extending the service life of the circular pipe 1 and preventing internal corrosion by corrosive substances.

[0030] Specifically, a gap of 0.5mm to 1.0mm is provided between the outer wall of the circular tube 1 and the inner wall of the steel pipe pole body 2. A sealing element 8 is installed within this gap. This design effectively prevents rainwater and dust from entering the interior of the steel pipe pole, protecting the internal structure from corrosion and damage. This design arrangement has multiple functions and advantages. First, it effectively prevents external impurities such as rainwater and dust from intruding into the internal space of the steel pipe pole, thereby avoiding corrosion or damage to the internal structure caused by these external factors. This design not only improves the service life of the steel pipe pole but also ensures the stability and reliability of its internal structure, thus providing strong protection for the safety and functionality of the entire structure.

[0031] Specifically, flanges 9 are provided at both ends of the steel pipe pole body 2. Each flange 9 has through holes that connect to the through holes 3. These through holes ensure smooth connection between the steel pipe pole and other structural components, thereby enhancing the stability and reliability of the overall structure. Through these through holes, the steel pipe pole can be fixedly connected to other components using bolts or other fasteners, ensuring the robustness and safety of the entire system.

[0032] Working principle: In operation, the circular tube 1 is made of high-strength steel, with a wall thickness designed to be 1 / 2 to 2 / 3 of the wall thickness of a steel pipe rod, to ensure structural strength and reduce weight. Both ends of the circular tube 1 are chamfered, with a chamfer depth of 1 / 4 to 1 / 3 of the tube wall thickness. This helps reduce stress concentration and improve the structure's fatigue resistance.

[0033] The round tube 1 has at least one reinforcing rib 5 along its axial direction, welded to the inner wall of the tube, to enhance its bending and torsional resistance. Anti-slip grooves 6 are provided at both ends of the round tube 1, extending along the axial direction of the tube to facilitate the fixing of the hanging screw 4 and prevent slippage. The inner wall of the round tube 1 is coated with an anti-corrosion coating 7 with a thickness of 0.1 mm to 0.3 mm. The coating material can be an epoxy resin layer or a zinc plating layer to improve the corrosion resistance of the round tube.

[0034] A gap of 0.5mm to 1.0mm is left between the outer wall of the circular tube 1 and the inner wall of the steel pipe rod body 2. The gap is filled with a sealing element 8 to prevent moisture and impurities from entering, while ensuring relative movement between the circular tube and the steel pipe rod. Flanges 9 are provided at both ends of the steel pipe rod body 2. The flanges have through holes that communicate with the through holes 3, which facilitates installation and maintenance.

[0035] Through the above structural design, the perforated structure inside the power steel pipe pole can effectively support power cables and has good corrosion resistance, fatigue resistance and structural stability.
