Description

Technical Field

[0002] Power towers are tower-shaped buildings used for power transmission. Their structural characteristics are that all types of towers are space truss structures, and the rods are mainly composed of single equilateral angle steel or combined angle steel. The rods are connected by rough bolts, which are connected by shear force. The whole tower is composed of angle steel, connecting steel plates and bolts. Individual parts such as tower feet are welded from several steel plates into a combination, so hot-dip galvanizing for corrosion protection, transportation and construction are extremely convenient. In addition, power towers require a large number of angle steels, so the reinforcement of angle steels is very important. The existing publication number CN216406357U discloses a reinforcement device for power angle steel towers, which uses wind energy to generate electricity during strong winds, thereby The limiting mechanism transmits electricity, thereby realizing remote detection of the stability of the connection between the base and the angle steel body, and can promptly send out a warning signal to the outside staff when there is a large looseness between the angle steel body and the base. At the same time, when the connection between the base and the angle steel body is relatively stable, the alarm is always in a power-off state, thereby saving electric energy. However, the reinforcement device requires a large number of screws and nuts to reinforce the angle steel, which requires time-consuming and labor-intensive disassembly and assembly by the staff, thereby greatly reducing the convenience of using the reinforcement device and bringing certain adverse effects to actual use, so it needs to be improved.
