Description

Technical Field

[0001] The invention relates to the technical field of electric power equipment, in particular to an earthquake-resistant pressure concrete electric pole. Background Art

[0002] As the name implies, electric poles are poles for electric wires. They appear in rural areas, fields, roads, and streets, and are one of the important infrastructures in early China. Later, due to the development of steel and reinforced concrete and technical requirements, these two materials replaced most wooden poles. With the development of steel and concrete, combined with technical exploration and the use of the principle of centrifugal force, reinforced concrete tapered cement poles and equal-diameter cement poles replaced most wooden poles. Cement poles are durable, corrosion-resistant, temperature-resistant, high-strength and crack-resistant. The diameter of equal-diameter poles is 300 to 550 mm; the wall thickness of both is 30 to 60 mm.

[0003] A Chinese patent with application publication number CN118757018A and main classification number: E04H12 / 12 discloses an earthquake-resistant concrete utility pole, including a utility pole body and a utility rack, and also including a first base, multiple groups of earthquake-resistant mechanisms and a first steel wire rope. A protrusion is fixedly provided on the first base, and the bottom of the utility pole body is fixedly connected to the protrusion. The earthquake-resistant mechanism includes a bolt assembly, an elastic member and a convex structure. The elastic member is arranged in a cavity in the middle of the convex structure, and the elastic member is connected to the convex structure through a bolt assembly. One end of the first steel wire rope is connected to the first base, and the other end is connected to the bolt assembly.
