Abstract
The utility model discloses a self-powered submarine pipeline on-line leak test device. The self-powered submarine pipeline on-line leak test device provided by the utility model consists of a continental rise monitoring center, a plurality of water level relay stations and a plurality of flow rate detectors. The flow rate detectors send flow rate signals of pipelines to a relay station closest to the water level; the water level relay station sends the signals to the continental rise monitoring center for treatment; the continental rise monitoring center compares the flow rate measurement value with the normal flow rate value or the previous flow rate detection value; when the flow rate measurement value deviates from the normal flow rate value or the previous flow rate detection value, alarms are sent out, and the position of a leak point is determined preliminarily. According to the utility model, the submarine pipeline on-line leak test device does not need an external power supply, has a self-powered function, sends the detected flow rate value to the continental rise monitoring center, and compares the measurement value with the normal value, determine whether pipelines leak, and estimates the position of the leak point preliminarily.

Technical field
The utility model belongs to submarine pipeline leak detection technology field, is specifically related to the online submarine pipeline leak test plant of a kind of self-powered.
Background technique
Pipeline leak detection mainly contains three kinds of methods: the one, and direct-detection namely utilizes the direct measuring channel external leakage of some sensors or detecting instrument thing content to judge with this whether pipeline leaks; The 2nd, indirect detection, namely by detecting the difference in flow of pipeline, the calculation of parameter such as pressure difference judge whether pipeline exists leakage; The 3rd, pipe interior detects, and namely gos deep into pipe interior by some remotely monitored sensors or small scale robot etc. and checks the pipeline spot failure, thereby accurately judge the leak source position.
Be at present mainly in order to detect a flaw and to hunt leak for the detection of large-scale delivering pipe, the former is for pipeline is repaired, and the latter rushes to repair pipeline.For flaw detection and the leak detection on-line measuring devices such as the online survey meter of industry, pipeline robot that use more.On-line measuring device is divided into probe portion and receiving part.Receiving part is at pipeline external, and the test section is connected with receiving part by cable, and cable provides power supply to the test section, and realizes both communication.Owing to using cable to connect, its operating range is restricted.
Simultaneously large-scale delivering pipe fluid flow inside has kinetic energy, utilizes pipe generator part kinetic energy can be converted to electric energy, is stored in it in storage battery or for detection facility by suitable rectification.
At present, domestic not yet have an online submarine pipeline leak test plant of mature and stable self-powered.
