AI Technical Summary

Problems solved by technology

The use of anti-corrosion coatings and galvanized layers to prevent corrosion of iron towers has the following disadvantages: (1) It cannot adapt to the humid and salty environment in coastal areas, and the service life of transmission towers in coastal areas is significantly shortened

And it cannot solve the problem that the corrosion of transmission towers is aggravated by factors such as air pollution caused by industrial development

(2) It is easy to cause various damages in the process of construction, handling, welding, etc., and the galvanized layer or paint layer loses its protective effect, which will accelerate the corrosion of the iron tower and form pitting corrosion

(3) Concrete is a porous material, and the junction between the root of the iron tower and the concrete foundation is most severely corroded. Oxidation and spalling of the foundation concrete, exposed ribs, and corrosion of foundation bolts are prone to occur. Hot-dip galvanizing and anti-corrosion coatings cannot affect the iron tower. to effective protection

However, this patent has the following disadvantages: (1) the device structure is complicated, installation is inconvenient, and it is not conducive to construction and maintenance; (2) the insulation cost of the high-voltage transmission line vibration power generation device is relatively high, and the economic benefit is poor; (3) the potential of the iron tower cannot be guaranteed to be maintained at all times Within the range of protection potential
