Problems solved by technology

Urban buried thermal pipelines are laid near the main roads of the city, and the impact of various production and living noises in the city also greatly interferes with audio detection, so audio detection technology is not suitable; the biggest technical defect of temperature-sensing optical fibers and temperature-sensing cables is non-heating Seasons cannot detect water leaks

Abstract

The invention discloses a buried heat distribution pipeline water leakage detection device and method. The device comprises four composite sensors arranged at the joint of the ith section of heat distribution pipeline and the (i + 1)th section of heat distribution pipeline of two adjacent sections, and each composite sensor comprises a connecting rod, a composite sensor box, a composite sensor, and a composite sensor box cover plate, and each composite sensor box is filled with a water swelling water stop strip. The method comprises the following steps of 1, laying a communication cable; 2, welding the connecting rods; 3, spraying and connecting polyurethane heat insulation layers; 4, installing a water leakage detection device; 5, burying the heat distribution pipeline and installing a data acquisition device on the ground; and 6, carrying out data acquisition and early warning of the composite sensors. The device and the method are reasonable in design and convenient and quick to install, can achieve the detection of water leakage in heating seasons, also can achieve the detection of water leakage in non-heating seasons, and improves the accuracy of water leakage detection.

Description

technical field [0001] The invention belongs to the technical field of pipeline detection, and in particular relates to a water leakage detection device and method for buried thermal pipelines. Background technique [0002] Urban buried thermal pipelines make full use of urban underground space to save ground space, but the problem of buried pipeline leakage is becoming more and more prominent. It has not only caused energy waste and increased heating costs, but also affects the heating of heat users. Therefore, the leak detection of buried pipelines has been troubled by heating companies. Thermal pipelines generally use spiral seam submerged arc welded steel pipes for ordinary fluid conveying pipelines, referred to as spiral steel pipes. The leakage accidents caused by the quality defects of the spiral welds are very small. During the construction of municipal buried heating pipelines, 2 ~After the assembly welding and flaw detection of 3 spiral steel pipes are completed,...
