Problems solved by technology
[0004] In practical applications, if the airflow or water flow stability is required to be high, the requirements for the change of the inner diameter of the pipe are relatively high. At this time, the detection of the inner diameter of the pipe is very important; The wall thickness of the pipe wall becomes thinner, etc., so that the pipeline has certain potential dangers, such as corrosion and cracking of oil pipelines and natural gas pipelines, etc.
However, there is no effective technical means in the prior art for detecting changes in the inner diameter of the pipeline.

The invention belongs to the field of pipeline detection and in particular provides a pipeline internal diameter change detection device and method. The pipeline internal diameter change detection device comprises an elastic ball, wherein the diameter of the elastic ball is greater than the internal diameter of a pipeline; an even number of laser emitters are arranged on the surface of the elasticballs in a uniformly-spaced manner; the even number of laser emitters can be located at the two ends of the same diameter of the elastic ball in pairs; the elastic ball is provided with a support atthe center position; the support is provided with a plurality of laser receivers correspondingly; the laser emitters and the laser receivers jointly achieve measurement of the distance between the surface of the elastic ball and the center of the elastic ball. The device and the method can effectively detect the change conditions of the internal diameters of various kinds of pipelines.
Description
technical field [0001] The invention belongs to the field of pipeline detection, and in particular relates to a pipeline inner diameter change detection device and detection method. Background technique [0002] A pipeline is a device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high-pressure part of the pipeline to the low-pressure part, and it can also be transported by the pressure or gravity of the fluid itself. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. [0003] The pipeline may be subjected to many kinds of external forces, including its own weight (the weight of the pipe, valve, pipe coupling, insulation layer and fluid in the pipe), the...
