摘要

管道猪在长远距离运输的油气管道应用逐渐成熟，然而现有的管道猪速度基本都是通过里程计采集数据计算得到，里程计采集的数据存在误差，并且该误差会随工作距离的增加而累积。本文设计了一种基于固-液摩擦纳米发电(SL-TENG)的管道猪速度传感器，通过传动装置判断速度与TENG速度传感器（VS-TENG）运动频率的关系；通过对VSTENG进行仿真模拟和材料改性，以及在不同频率和温度的工况下实验和耐久性测试，验证了VS-TENG将机械能转化为电能的可行性；拟合了发电电流与速度的函数，证明了VS-TENG作为速度传感器的可行性，为管道猪速度测量提供了新的参考和思路。

Abstract

The application of the pipeline inspection gauge(PIG)in oil and gas pipelines for long-distance transportation is gradually maturing.However

the velocity of the existing PIG is basically calculated from data collected by an odometer.There are errors in the data collected by an odometer

and the errors accumulate with the increase of working distance.In this paper

the velocity sensor of the PIG based on a solid-liquid triboelectric nanogenerator(SL-TENG)is designed.The relationship between the velocity and the motion frequency of the TENG velocity sensor(VS-TENG)is judged by the transmission device.The feasibility of the VSTENG converting mechanical energy into electrical energy is verified by the simulation and material modification for the VS-TENG

experiments and durability tests at different frequencies and temperatures.The function relating the generated current and velocity is fitted

which proves the feasibility of the VS-TENG as a velocity sensor and provides a new reference and idea for the velocity measurement of the PIG.
