摘要
Abstract
Severe ice icing caused by extremely cold weather with ice and snow may lead to accidents such as line breakage.With the development of artificial intelligence technology,de-icing robots have become a reliable force to ensure the stable operation of power lines in extremely cold weather.In order to improve the de-icing efficiency,aimed at glaze-type icing with relatively high hardness,based on the conventional impact de-icing device of the de-icing robot,this paper proposes a design scheme of an eccentric de-icing hammer knocking de-vice,which utilizes the vibration of the line to reduce the adhesion force of the icing.At the same time,this pa-per puts forward a vibration mathematical model of the knocking de-icing robot-overhead line,and analyzes the line galloping situation when the robot is de-icing and the relationship between the rotation speed of the de-icing hammer and the line displacement.For the icing of snowflake and glaze-type icing,the knocking de-icing robot is used for de-icing in the climate laboratory,and the vibration displacement characteristics of the middle part of the line during the de-icing work of the robot are obtained.In addition,the de-icing process is simulated through ANSYS simulation,and the experimental results are compared with the calculation results.The results show that the vibration displacement and frequency of the line increase with the increase of the rotation speed of the de-icing hammer of the robot and the thickness of the ice icing;the de-icing effect is the best when the robot uses the impact of the de-icing knife in cooperation with the striking and rotation of the de-icing hammer for de-icing;in order to save energy,for the snowflake icing,the de-icing hammer can be used only for striking and ro-tating to shake it off.For the ice icing with a thickness of 0 mm～10 mm,only the impact of the de-icing knife can be used for removing it,and for the ice icing with a thickness exceeding 10 mm,the two methods need to be used in coordination for removal.关键词
