Online measuring device for icing strength on surfaces of materials and real-time monitoring system for icing process

Abstract

The invention relates to an online measuring device for the icing strength on the surfaces of materials and a real-time monitoring system for the icing process. The online measuring device for the icing strength on the surfaces of materials includes a centrifugal test module and a data collection module. The centrifugal test module includes a fixed bracket, an annular water-cooling box, a sample turntable and an icing mold arranged from bottom to top. The fixed bracket is equipped with a lifting drive mechanism, and the annular water-cooling box is connected with the lifting drive mechanism. The fixed bracket is also equipped with a stepping motor of which the output shaft passes through the annular water-cooling box to be fixedly connected with the sample turntable. The data collection module includes a metal shield and a vibration sensor, as well as a controller for collecting the speed signal of the stepping motor and the signal of the vibration sensor. In addition to accurately measuring the ice adhesion strength on the surfaces of different materials, the online measuring device can also analyze the influences of the temperature, the humidity, the raindrop size, the impact speed of raindrops, the wind speed and the wind temperature on the freezing time of water drops on the surface of a sample to be measured, the ice thickness, the ice adhesion strength and the energy consumption of ice melting and provide guidance for the research and development of anti-icing materials.

Description

technical field

[0001] The invention relates to the technical field of research and development of anti-icing materials (coatings), in particular to an on-line measuring device for the icing strength on the surface of materials and a real-time monitoring system for the icing process. Background technique

[0002] Icing will bring a lot of inconvenience to people's production and life. For example, in 2008, the South suffered from a large-scale ice and snow disaster, which was rare in history. The power grid was paralyzed, the transportation was interrupted, and the crops were not harvested. The direct economic loss exceeded 150 billion. Therefore, research on anti-icing materials (coatings) has become the focus of researchers in China, the United States, Canada and other countries that often suffer from icing hazards. Most of the existing icing tests are designed to observe the icing conditions of transmission line insulators, conductors and various roads. Since the discov...
