Description

Technical Field

[0001] The utility model relates to the technical field of iron tower lightning protection, in particular to a lightning protection device for an iron tower of a power transmission line. Background Art

[0002] Transmission line towers are tower-shaped structures used for power transmission. Their structural characteristics are that all tower types are spatial trusses, with members primarily composed of single equilateral angle steel or composite angle steel. Members are connected using crude bolts, which are shear-resistant. The entire tower is composed of angle steel, connecting steel plates, and bolts. Some components, such as the tower foot, are welded together from several steel plates. Therefore, hot-dip galvanizing is used for corrosion protection, making transportation, construction, and erection extremely convenient.

[0003] According to application number 202321061483.7, a lightning protection device for a transmission tower is disclosed. The device comprises a mounting plate, on which a lightning rod body is mounted, and further comprises: a positioning seat integrally connected to the mounting plate; a socket fixed to the lower end of the lightning rod body, the socket being insertable into the positioning seat and secured via a threaded ring; a fastening assembly arranged at an angle, one end of which is connected to the middle of the lightning rod body via a positioning ring; and a hook fixed to the mounting plate, with the other end of the fastening assembly hooked to the hook.

[0004] The device's positioning base and socket cooperate to connect, initially securing the lightning rod. A threaded ring is then used to reinforce the connection. Multiple fastening components simultaneously exert tension on the rod in multiple directions, enhancing the rod's restraining effect and ensuring its stability. However, the device requires four bolts to secure the lightning rod, making installation cumbersome and inconvenient. Utility Model Content
