Pulling tool capable of generating power of pipeline detector

Abstract

The invention discloses a pulling tool capable of generating power of a pipeline detector, and the pulling tool is used for pulling the pipeline detector. The pulling tool consists of a supporting body, a power generating system and a speed regulating system, wherein the two ends of a framework are provided with leather cups to form the supporting body; a motor is sequentially connected to a speed reducer and a speed regulating valve so as to form the speed regulating system with a speed sensor and a control unit; a pressing wheel mechanism, a power generator gearbox and a power generator are sequentially connected so as to form the power generating system with a storage battery. The control unit, the power generator, the storage battery and the motor are sealed in a sealed cabin; and the sealed cabin is mounted in the framework. Under the action of a tension spring, a pressing wheel clings to a pipeline inner wall; when a fluid in a pipeline drives the pulling tool to move, the pressing wheel is driven to rotate, and the power generator is driven to generate powder after the speed of the pulling tool changes, and the electric energy is stored in the storage battery. Under the action of the speed regulating system, the whole detector is almost stable in operation speed, so that the detection data is more precise and reliable; and meanwhile, in the operation process of the detector, the power generating system is always in a power generating state, so that sufficient electric quantity is provided for the whole detector.

Description

technical field [0001] The invention relates to pipeline detector technology, in particular to a traction tool for pipeline detectors capable of generating electricity. Background technique [0002] As an efficient, safe and economical means of transportation for fluids such as oil, natural gas, and tap water, pipelines are affected by galvanic corrosion, fatigue damage, fluid erosion, defects in the pipeline itself, and damage from third-party construction, as well as natural disasters such as mountain torrents, debris flows, and earthquakes. After running for a period of time, problems such as corrosion and perforation, mechanical cracks, and pipeline deformation will inevitably occur, resulting in reduced pipeline delivery capacity and efficiency, pipeline leakage, and even fires, explosions and other vicious accidents, which will not only cause huge economic losses and impact Normal production and living order will damage the credibility of the government, and it will al...

AI Technical Summary

Problems solved by technology

However, due to the wide range of fluid flow velocity in the pipeline, especially when the flow velocity is low, the detector's operating speed and power generation cannot be guaranteed

In addition, the rotation of the impeller will affect the stability of the detector's running speed, thereby reducing the accuracy and reliability of the detected data.
