Method of On-line Obtain Energy for Medium Differential-pressure Drive In-pipe Robot
摘要
Abstract
In this study,a new research method of on-line energy obtaining with friction wheel is proposed,and the operation regulation mechanism of a new type of cone valve regulating in-pipe robot driven by medium differentialpressure is described.We analyze the relationship between operating speed,difference pressure and driving force of the in-pipe robot driving unit under working condition and obtain,the load characteristics.With modeling the fluid system by using CFD software,we establish reasonable parameters and meshing to verify the actual conditions of the load characteristics,and the simulation results show that the energy demand of in-pipe robot detection operation is no less than 200 W.Based on energy parameters and the technical requirements the inner wall pressure needed no more than 800 N in the pipeline industry,we develop a friction wheel on-line energy obtaining unit with on-demand automatically start-stop control,adjustable pressure,easily overcoming obstacles and other functions.The on-line energy obtaining unit cooperatives with the driving unit to realize the on-line energy obtaining and storage in the battery.The method provides a new solution to the energy supply of the in-pipe robot in long distance transportation pipeline.关键词
