Problems solved by technology
However, when measuring the length of pipelines buried underground, in rivers, buildings or even under mountains, it is impossible to directly use conventional rulers for accurate measurement
The existing measurement technology is to conduct indirect calculation and measurement by inputting quantitative water and other measurable media, or to carry out line inspection measurement through special equipment. The problems brought about are high requirements on geological conditions, low measurement accuracy, and inability to measure Pipelines made of other materials, pipelines that cannot measure media such as water or a large amount of water vapor

The invention discloses a waterproof small-bore pipeline length measuring system and a method. The waterproof small-bore pipeline length measuring system comprises a vehicle body matched with a small-bore pipeline and a length measuring mechanism installed at the tail end of the vehicle body, and the length measuring mechanism comprises a base connected with the vehicle body, and further comprisesa supporting wheel and two measuring wheels arranged on the base; the method includes the steps: firstly, a waterproof small-bore pipeline length measuring system body is installed; secondly, a high-pressure power source start-up system is introduced; thirdly, small-bore pipeline length data are collected; fourthly, the small-bore pipeline length data are derived; and fifthly, the small-bore pipeline length is estimated. According to the waterproof small-bore pipeline length measuring system and the method, the vehicle body and the length measuring mechanism are sealed, the pipeline length ismeasured through the two measuring wheels, the precision is high, the pipeline lengths of metal pipe pipelines and non-metal pipepipelines which are empty or contains liquid are measured, the vehiclebody is pushed through the external high-pressure power source, the electric energy consumed by additionally installing a driving device on the vehicle body is reduced, the battery life is prolonged,and the waterproof small-bore pipeline length measuring system can smoothly pass through drift diameter elbows with 1.5 times.
Description
technical field [0001] The invention belongs to the technical field of measuring the length of small-diameter pipelines, and in particular relates to a waterproof small-diameter pipeline length measuring system and method. Background technique [0002] In industry and daily life, steel pipes are mainly used to transport various fluid media, including sewage, clean water, oily water, crude oil, etc. Often, it is necessary to measure the length of a certain section of pipeline, such as pipeline anti-corrosion construction. However, when measuring the length of pipelines buried underground, in rivers, buildings or even under mountains, it is impossible to directly use conventional rulers for accurate measurement. The existing measurement technology is to conduct indirect calculation and measurement by inputting quantitative water and other measurable media, or to carry out line inspection measurement through special equipment. The problems brought about are high requirements on...
