Description

Technical Field

[0001] The utility model relates to the technical field related to steel pipe poles, and more specifically, to a high-voltage overhead power transmission and transformation steel pipe pole. Background Art

[0002] Transmission lines can be divided into overhead transmission lines and underground transmission lines according to their structures. Overhead transmission lines are composed of line towers, conductors, insulators, etc., erected on the ground to transmit alternating current. High-voltage overhead transmission and transformation steel pipe poles are a new type of power equipment for erecting power lines that have emerged in recent years. They are an alternative to traditional cement column line towers.

[0003] For the convenience of transportation and installation, the current power transmission and transformation steel pipe poles generally adopt an assembled structure. Multiple sections of power transmission and transformation steel pipe poles are combined into line pole towers to replace traditional cement column poles. The power transmission and transformation steel pipe poles are connected by flanges and bolts. However, in the existing power transmission and transformation steel pipe poles connected by flanges and bolts, the strength of the flange connection part cannot be guaranteed, and the protection effect of the flange connection part is poor. After long-term use, the flange connection part is prone to oxidation and rust, which is prone to safety hazards. Utility Model Content

[0034] In this embodiment, preferably, a hexagonal groove 208 is opened on the first edge 204, and a nut 209 is fixedly provided in the hexagonal groove 208; the nut 209 is placed in the hexagonal groove 208, and the hexagonal groove 208 makes it difficult for the nut 209 to rotate.

[0038] The working principle and use process of this utility model:

[0039] During on-site construction, the transmission and transformation steel pipe pole bodies 100 are butted together through the connecting flange 101 and locked with the first bolt 102. The ring 207 at the middle position of the first reinforcement side plate 201 and the second reinforcement side plate 202 is aligned with the connecting flange 101 and snapped onto the connecting flange 101. The limiting column on the second edge 205 can be inserted into the limiting groove 2012 on the first edge 204 for positioning.

[0040] Subsequently, the nut 209 is placed in the hexagonal groove 208, and the second bolt 206 passes through the receiving groove 2010 and is threadedly connected to the nut 209, so that the first reinforcement side plate 201 and the second reinforcement side plate 202 are combined together and locked on the outside of the power transmission and transformation steel pipe pole body 100, and the first reinforcement side plate 201 and the second reinforcement side plate 202 are provided with a reinforcement horizontal plate 301 and a reinforcement vertical plate 302 to strengthen the force strength of the connection part of the power transmission and transformation steel pipe pole body 100, so that when the upper power transmission and transformation steel pipe pole body 100 is subjected to external force, the connection part between it and the lower power transmission and transformation steel pipe pole body 100 is not easy to break;

[0041] Moreover, when the second bolt 206 and the nut 209 are tightened, the sealing rings 203 on the inner sides of the first reinforcing side plate 201 and the second reinforcing side plate 202 contact each other, so that the connection part of the power transmission and transformation steel pipe pole body 100 is sealed, thereby preventing external precipitation from flowing into the connection part along the gap between the power transmission and transformation steel pipe pole body 100 and the first reinforcing side plate 201 and the second reinforcing side plate 202, causing corrosion of the connecting flange 101 and the first bolt 102.
