Heat supply pipeline leakage detector based on magnetism, heat, sound, electricity and humidity trenchless detection

Abstract

The invention provides a heat supply pipeline leakage detectorbased on magnetism, heat, sound, electricity and humidity trenchless detection, which is used for solving a problem that time, manpower and material resources are wasted because the detection angle is single and a trenchless heat supply pipeline leakage point is not easy to quickly and accurately judge. Three metal wheels which are arranged in a triangular shape of the detector are installed on a structural member, and a pickup is connected with the metal wheels; a data acquisition center is mounted on the thin bottom plate and consists of a battery power supply, a collector assembly, a sensor assembly and a wireless routing module; the collector assembly is composed of a central processing unit, a weak magnetic collection module, an infrared collection module, an audio collection module, an electric field collection module and a humidity collection module. The sensor assembly is composed of a weak magnetic sensor, an infrared temperature sensor and a humidity sensor. The detector is advantaged in that accuracy of heat supply pipeline leakage point judgment can be greatly improved, a large amount of manpower and material resources are saved, and leakage point searching efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of pipeline detection, in particular to a non-excavation detection instrument for heating pipeline leakage based on magnetism, heat, sound, electricity and wetness. Background technique [0002] With the rapid and stable development of my country's economy and the rapid advancement of rural urbanization, the penetration rate of urban heating systems has increased rapidly. The urban heating pipeline system will inevitably face a variety of problems. Because the thermal pipeline is often affected by various factors such as traffic load, it is prone to cracks and other situations. Various reasons lead to the frequent occurrence of pipeline leakage accidents. But because they are all laid underground, it brings inconvenience to the daily thermal pipeline inspection. [0003] At present, the leakage detection of heating enterprises mainly uses water leakage detectors, leak detectors, or pressure pipe leak teste...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem that due to the single detection angle, it is difficult to quickly and accurately judge the leakage point of the non-excavation heating pipeline, resulting in the waste of time, manpower and material resources, and the low efficiency of the repair work of the leakage of the heating pipeline, the embodiment of the invention provides a Based on the magnetic, thermal, acoustic, electric and wet non-excavation detection heating pipeline leak detector, it can comprehensively judge the leakage point of the heating pipeline from five aspects, which can greatly improve the accuracy of the judgment of the leakage point of the heating pipeline, fast and accurate Find the leakage point of the heating pipeline, save a lot of manpower and material resources, and improve the work efficiency of the leakage repair of the heating pipeline
