The utility model relates to a weather-resistant steel tower corrosion resistance monitoring device

About: The technology provides a corrosion resistance monitoring device for a weather-resistant steel tower, including a drone and a corrosion thickness gauge. A corrosion thickness gauge is installed under the center of gravity of the drone body, and the probe of the corrosion thickness gauge is connected to the corrosion thickness gauge body through the probe telescopic cylinder. A camera is installed on the front side of the drone, and the corrosion thickness gauge and camera are connected to the controller of the drone through the data line. The controller is connected to a portable monitoring terminal via a wireless module. The technology realizes the remote monitoring and remote control of the corrosion resistance of the tower, saving time and effort, and the operation is safe. The UAV is used to fly and move the corrosion thickness gauge, which can quickly measure the corrosion resistance layer thickness of the weather-resistant steel tower, and can measure the corrosion resistance thickness at different height positions. The telescopic cylinder is used, and the cylinder has an elastic buffer effect during the expansion process. When the probe touches the Angle steel of the tower, it can play a role in protecting the probe.

The utility model relates to a shock absorber for monitoring the corrosion resistance layer of a weather-resistant steel tower

About: The technology provides a damping device for monitoring the corrosion resistant layer of a weather-resistant steel tower UAV, including a damping device installed between the body of a corrosion thickness gauge and the body of the UAV. The damping device comprises a damping rubber pad and a damping groove. Flannel is arranged on the upper side of the body of the corrosion thickness gauge, and the flange is fixed on the UAV through screws. It is connected on the screw and located between the flange and the UAV. The shock absorber groove is arranged on the upper end face of the corrosion thickness gauge body, and the shock absorber steel ball layer is arranged in the groove. The technology is equipped with a shock absorber, which can avoid the small shaking of the UAV or the vibration generated by the flight component to isolate the shock absorber, and improve the measurement accuracy of the probe. The shock absorber rubber pad and the shock absorber groove structure equipped with shock absorber beads can play a double shock absorber role, and better avoid the vibration of the probe measurement accuracy.

8 A weather-resistant steel tower and its formulation technology

The technology provides a weather-resistant steel tower. The weather-resistant steel comprises the following components according to mass fraction :C: ≤0.16%, Si: ≤0.65%, Mn: ≤1.5%, P: ≤0.020%, S: ≤0.010%, Cu: 0.25‑0.55%, Cr: 0.30‑1.25%, Ni: ≤0.65%, Sb: ≤0.2%, and Ti, V, Nb and Alt alloys, the total amount of Ti, V, Nb and Alt alloys does not exceed 0.22%, the rest is Fe and unavoidable impurities. Weathering steel profiles are obtained by putting the concentrate into the furnace, smelting, refining, continuous casting, rolling and cooling, and the profiles are formed into the iron tower after drilling and forming and splicing or welding. The technology enables the self-protective oxide layer thickness of weather-resistant steel to reach 0.5mm, which can be used in the complex climate environment of Guizhou. The process research of weather-resistant steel for the steel tower can optimize the process flow, save weather-resistant steel materials and production costs, and improve production efficiency.
