[0002] Power line steel pipe poles are made of steel materials such as polygonal steel pipes and round steel pipes, and are treated with hot-dip galvanizing or hot-spray zinc coating for corrosion protection; they are mainly used for power line erection and are a replacement for traditional cement poles.

[0003] Chinese Utility Model Announcement No. CN218408060U includes an upper rod and a lower rod, with a first flange and a second flange respectively provided at opposite ends of the upper and lower rods. A connecting assembly is provided between the upper and lower rods, the connecting assembly including an inner clamping ring and an inner insert rod, the inner insert rod being located at the center of the inner clamping ring, with its upper and lower ends respectively inserted into the interior of the upper and lower rods. This utility model improves overall strength by providing a connecting assembly inserted into the interior of the upper and lower rods; furthermore, the inner insert rod significantly improves the alignment and installation efficiency of the upper rod; and the retaining ring covering the outer ring side of the first and second flanges further improves overall stability and reliability, and reduces the burden on bolts.

[0004] The applicant discovered some shortcomings in the use of the patent: the combination of the retaining ring and the flange forms a protruding position, which can easily become a temporary foothold for birds. Bird droppings are corrosive, and long-term contact with droppings may damage the retaining ring and the flange.

[0005] Therefore, this utility model designs an assembled modular steel pipe pole to solve the problems existing in the prior art. Utility Model Content

[0008] Preferably, the fixing assembly includes two flange grooves, which are respectively opened at the top and bottom of the disc, and the flange grooves and the flange are inserted into each other. Insert blocks are installed at the middle of the top and bottom of the disc, and the two insert blocks are slidably connected to the inner walls of the main steel pipe rod and the auxiliary steel pipe rod, respectively. Several threaded holes communicating with the flange grooves are opened on the outer side of the disc. The flange and the threaded holes are connected by hexagonal bolts. The insert block at the bottom of the disc is inserted into the top of the main steel pipe rod, so that the flange at the top of the main steel pipe rod is inserted into the flange groove at the bottom of the disc. Then, the flange at the bottom of the auxiliary steel pipe rod is inserted into the flange groove at the top of the disc, so that the insert block at the top of the disc is inserted into the bottom of the auxiliary steel pipe rod. Finally, the hexagonal bolts are screwed between the two flanges and the threaded holes to complete the assembly of the main steel pipe rod and the auxiliary steel pipe rod. This installation method reduces the burden on the hexagonal bolts.

[0009] Preferably, the connecting assembly includes four screw holes, which are respectively opened at both ends of the left and right protective covers. The two screw holes at both ends are connected by a stainless steel screw. The left and right protective covers can be fixed by turning the stainless steel screw into the screw hole.

[0010] Preferably, the outer walls of the left and right protective covers are provided with a waterproof coating, which is a polyurethane waterproof coating, to improve the waterproof effect of the left and right protective covers.

[0011] Preferably, the top of both the left and right protective covers is provided with threaded grooves that are threaded to the protective cone, and the lower side of the outer wall of the protective cone is provided with threads. When a protective cone is damaged, it can be rotated out of the threaded groove, making it convenient to replace the damaged protective cone individually.

[0012] Preferably, the left and right protective covers are provided with sealing strips on the sides that are close to each other, which can improve the sealing between the left and right protective covers.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses left and right protective covers to completely cover the flange and disc, which can reduce dust and impurities adhering to the flange and disc. Then, by installing several protective cones on the top of the left and right protective covers, there are no footholds for birds on the top of the left and right protective covers, thus avoiding the corrosion of the flange and disc by bird droppings.
